Terminal storage life can be long or short, long months years, short days, weeks, some need to make long-term inventory plan for customers, while others order production immediately out of storage. Terminal reliability and storage life can be improved by adopting a first-in, first-out inventory strategy, a traceability label system, proper packaging, corrosion prevention, improved storage conditions, and proper terminal material and design. https://www.bossgoo.com/product-detail/insulated-female-connectors-connector-copper-lugs-61373843.html Terminals are often exposed to a number of different environmental factors, such as during transportation and storage, during manufacturing, during installation, maintenance and end-customer use. These environmental factors can be understood as given conditions, which can be subdivided into temperature, humidity, corrosion, pollution, internal and external conditions, and human factors. The duration of exposure to changing conditions from these environmental factors must also be defined. Storage, high-current terminal storage environments vary from controlled clean, heated or air-conditioned, damp warehouses, offices or factories to uncontrollable corresponding environments. The service life of the terminal is seriously affected by heat, humidity, or corrosion. In these uncontrolled environments, weldability storage life is greatly reduced by oxidation, corrosion, and increased metallization; The surface and function of metal devices are affected by rust, patina and other forms of corrosion; Plastic as an insulating material can also be affected by deterioration of its flexibility, strength and shape. Wiring terminals are generally composed of shrapnel, conductive parts and insulating parts (plastic case). When wiring, the screwdriver import plastic shell on the right side of a square hole, upward tilt screwdriver, give a downward pressure shrapnel, shrapnel square hole can be aligned with the conductive wire frame of holes, again from plastic shell hole into the wire, make it into the conductive parts so as to realize the connection of wires and terminals, wire connection, then the terminal plug and fixed on the circuit board supporting the socket connection, Can realize the circuit board to transmit signal function. It should be pointed out that when the socket of the wiring terminal block is connected with the plug, the solder feet (or conductive parts) in the socket can achieve seamless contact with the conductive parts in the plug, so as to ensure good conductive effect. The unwiring process is similar to the wiring process. Press the spring downward with a screwdriver and pull out the conductor directly from the conductive part.

Contact force is one of the basic elements in terminal blocks. If there is not enough contact pressure, a good conductive material is of no use. Because, if the contact force is too low, there will be displacement between the wire and the conductive sheet, resulting in oxidative pollution, so that the contact resistance increases and lead to overheating. In the case of the DRTB2.5 pressed wire frame assembly, an actual contact force of up to 750N can be generated by applying only 0.8Nm of torque to the screw, independent of the wire cross section. Therefore, the use of terminal crimping frame has no environmental influence, large contact area, large contact force permanent connection. Voltage drop small contact voltage drop size is also one of the dimensions to identify the quality of the wiring block. Even with a small force distance applied to the screw, the voltage drop value is still significantly lower than the limit required by VDE0611. Meanwhile, the applied torque varies over a wide range and the voltage drop is almost constant. Therefore, although different operators use different amounts of torque, it does not affect the quality of the connection. This is another proof of the reliability of the crimping frame at the terminal. A contact force with a large self-locking function is meaningful only if it is persistently applied to the wire. https://www.bossgoo.com/product-detail/non-insulated-spade-terminals-61374045.html The terminal uses the crimping frame for maximum reliability in this respect. During the screw tightening process, the threaded tongue on the crimping frame springs up, resulting in a reaction force against the screw. The change in wire diameter due to temperature is offset by the elastic action of the wire pressing frame itself, so there is no need to tighten the screw again. The wire frame was subjected to an aging test for 168 hours at 130oC, followed by a vibration test for 168 hours at 20 times the acceleration of gravity. After completing these more rigorous tests than VDE0611, the wire pulling force from the wire frame is still more than VDE0611 specified As much as six times higher, and the voltage drop remains constant. This shows unequivocally the maintenance-free nature of the crimping frame at the terminal. Air-tightness various environmental factors, such as temperature and humidity of the air a definitive effect on the terminal, terminal must have the ability to endure the test of adverse environmental factors, according to the regulation of DIN41640. 76 of the test and practical experience has shown that even in connection with no end of pressure under the condition of soft wire, wire frame can maintain its airtight performance.

It is stipulated that when stripping the sheath of the conductor (cable), the conductor core shall not be harmed and the metal material of the conductor core shall be exposed. The length of cable sheath to be peeled off when using cage terminal cold-end terminal should comply with the requirements of Table 1; Is a face of wiring and his cage play yellow cabling is not clear when the length of the wire stripping, the special screwdriver inserted into the first cold pressing terminal processing technology of square hole, make cold end Huang Kong stretches out of bullets, plug the cable into deep cold-press terminal round hole met frictional resistance (by), remove the special screwdriver, plugged into a special screwdriver, remove the wire, In this case, the length of wire imprinting distance is the length of the end line of the cord end terminal. Step 2 Clean the surface https://www.bossgoo.com/product-detail/vinyl-wire-end-caps-insulated-terminal-61373436.html Before installing cord end terminals and wires, carefully clean the strip cores and cord end terminals. Ensure that smooth exposed wires are only conductive materials and dirt. Clean the cord end terminals inside. The detection method is estimation. Step 3 Insert the core wire into the cord end terminal cover When inserting the stripped core into the cord end terminal cover, insert all the cores into the terminal. The detection method is estimation. Cord end terminal Cord end crimping The conductor terminal to the conductor must be crimped with a special network cable pliers. The detection methods in this section are all estimation. The cross section of the conductor must conform to the specifications and models of cord end terminals. The shaft rod of the special crimping tool should be consistent with the cross section of the wire, and the network cable pliers must be within a relatively limited time limit. The crimping part is in the middle of the cord end terminal cover. The crimping part is properly specified. When using v-shaped rod crimping pliers, it should be imprinted on the bottom of the cord end terminal cover. The crimping part is properly specified. When using the special tool of endless bit equipment, the rocker of the special tool must be pressed to the bottom to achieve the physical properties specified in Note 3. Specify rocker thorough pressure exactly. 66mm2 and above tubular terminal cord end terminal crimping end when inserting the terminal into the spring yellow terminal, touch the large cross-section of the tubular terminal with the spring yellow metal sheet. The large-cross section housing is oriented toward the cord end terminal management center. Step 4 Installation of wire identification (line number) When the heat-shrinkable casing is used as wire marking, the wire marking should be set on the wire before crimping, and then the crimping work should be carried out. Do not use the heat shrink tubing on the one-sidedness of the cord end terminal. If a yellow cage terminal is used, the heat shrink tubing should be used at the place where the cable jacket is removed from the distance of 11mm. The insertion of wire marking shall be the insertion of marking data or English letters along the radial direction of wire. When marking the horizontal position, the data or English letters should be aligned (to the operator), and the data bits (the last bit) should be away from the cord end terminal, as shown in Figure 7 to Figure 8. The standard mark is symmetrical and clear, and the orientation is appropriate. The fifth step is detection method The detection method is meter scale estimation. Suitable cord end terminals should be used according to the cross section of the wire, and the specifications and models should be exactly the same. The length of cable sheath stripped meets the requirements and the specified length is appropriate. All the wires of the wires are completely wrapped in the cord end terminal, and there is no scattered copper wire. The crimping part meets the requirements, and the specified crimping part is appropriate.

We usually say Insulated Terminals have what bad problems, there are many reasons is caused by improper use, terminal plastic insulation materials and conductive parts is directly related to the quality of the terminal, a lot of the time our technical operation error, terminal blocks appear problem, must touch the part of the conduction conduction, and secure touch firmer. Insulation parts should not be conductive must be insulated. Most of the time the problem of the terminal is poor contact, there will be a touch layout planning is not very reasonable. https://www.bossgoo.com/product-detail/insulated-spade-type-crimp-on-connectors-61372438.html We are used when you need to pay attention to the Connecting Terminals, the insulation of the terminal needs to be considered bad problems, in order to make the insulation effect is good, must adhere to the correct orientation, terminal has good electrical connection function, if improper operation, will cause the terminal leakage phenomenon, also can cause terminals in advance ageing, as well as the short circuit phenomenon. Xiaobian in the design and manufacturing process, all kinds of problems in the process of use were tested in practice, so as to prevent problems in the first, and develop detailed specifications for customers.

To solve the problem when using the terminal, pay attention to the following phenomena: The first phenomenon: the wiring terminal is not in good contact. The metal conductor inside the wiring Connecting Terminals is the core part of the terminal. It transfers the voltage, current or signal from the external wire or cable to the contact corresponding to its matching connector. Therefore, the contact must have excellent structure, reliable contact holding force and good electrical conductivity. The second phenomenon: poor insulation of the terminals: the function of the insulator of the Insulated Terminals is to keep the contacts in the correct position, and to insulate each other between the contacts and the contacts and between the contacts and the shell. Therefore, the insulating parts must have excellent electrical properties, mechanical properties and process forming properties. Especially with the widespread use of high-density and miniaturized terminal blocks, the effective wall thickness of insulators is getting thinner and thinner. Third phenomenon: Poorly fixed terminal block insulators not only insulate, but also usually provide accurate neutralization protection for extended contacts, and also have the function of installation, positioning, locking and fixing to the equipment. Bad fixation, light influence contact reliability resulting in instant power failure, serious is product disintegration. https://www.bossgoo.com/product-detail/electrical-copper-pre-insulated-ring-terminal-61372108.html

Screw connection terminals have been playing an important role in the electronic industry and have now become an important component of printed circuit boards. Its structure takes into account the characteristics of convenient wiring and firm screw connection. Spring connection terminals, spring connection PCB terminals are divided into two types: pull-back spring connection and butterfly spring connection. The pull-back spring terminal and screw terminal can be compatible with each other, greatly increasing the flexibility. Reliable connection, front connection, visible connection, low maintenance, no tightening required. https://www.bossgoo.com/product-detail/insuated-ring-copper-terminals-and-connectors-61372253.html The wiring terminal uses the existing rail type wiring Insulated Terminals RTB connection technology, and adds the circuit composed of electronic components, to realize the transmission and coupling of photoelectric process. Automatic control is the core of the control unit must be isolated from various sensors and actuators in a reliable way, in order to avoid interference, the RPC light insulation terminal is able to accomplish this function, and to ensure that the signal with the electronic control device of low voltage required to match, can also be peripheral devices and control of the process control, signal and regulator device interfaces between components, And suitable for different voltage and power range.

Once the copper pipe terminal fire, the fire fierce, agile extension, when burning a lot of harmful gas, constitute a difficult remedy. After the copper tube terminal is burned out, the correction time is long and the loss is severe. Therefore, great attention must be paid to prevent the copper tube terminals fire. So what are the factors that lead to high voltage copper pipe terminal accidents? https://www.bossgoo.com/product-detail/ks-tinned-copper-cable-terminal-lugs-61371147.html 1. The site conditions are relatively poor. The environment and technical requirements of copper pipe terminals and joints are very high when they are manufactured in the factory, while the temperature, humidity and dust at the construction site are not well controlled. 2. The installation is not strictly in accordance with the technical construction or technical rules without considering the questions that may be presented. Dc withstand voltage test is selected for completion inspection to constitute anti-electric field in the joint, resulting in insulation damage. 3, due to poor sealing treatment. The center joint must choose the metal copper shell plus PE or PVC insulation anticorrosive layer of the sealing structure, in the field construction to ensure the tightness of the lead seal, so effectively ensure the sealing waterproof function of the joint. 4, copper pipe terminal construction process in the insulation surface will inevitably leave subtle skid marks, semi-conductive particles and sand on the emery cloth may also be embedded in the insulation, other joint construction process because of insulation exposure to the air, insulation will also inhale water, these leave danger for long time safe operation. 5, the brass terminals material itself and the brass terminals manufacturing, installation, inevitably exist in the process of terminal manufacturing defects, the operation of the electric heating, chemical, environmental factors influence, the insulation of the brass terminals will attack different degree of aging, the aging will eventually led to the outbreak of the brass terminals with.

Terminals are anti-oxidation and anti-corrosion. Part of the circular, fork terminal in the same specification and electrical connection part is divided into different widths, to adapt to different customer width needs. The terminal insulation sleeve is funnel-shaped, easy for wire insertion, and the color is divided according to the international code area, can clearly distinguish the wire range. Selection of fine thick copper plate to ensure user safety. The thickness of the terminal will directly affect the current load, temperature and pressure strength. High quality welding terminal, to ensure that there will be no crack after pressing, in the harsh use of the environment, still can have a strong and reliable pulling force. Terminal is able to achieve safe, reliable, effective connection, especially in the use of high current, high voltage environment is widely used. Spring type, is the use of spring device of the new type of terminal, has been widely used in the world electrical and electronic engineering industry, lighting, elevator control, instrumentation, power supply, chemistry and automotive power.

Unswerving, professional quality. https://www.bossgoo.com/product-detail/insulated-socket-connectors-f5-5b-61373726.html The important role of wiring terminals. Terminal it is the use of the latest connection technology developed and become, which adds a lot of electronic application components. Contains a highly complex circuit system to achieve photoelectric transmission. In fact, the core of the terminal is the control element inside, it is well isolated from the sensor and the actuator, do not interfere with each other, can be very good to ensure that the signal is consistent with low voltage, but also can be very good control of other equipment, can also apply to different working voltage. In addition, the terminal also has a strong ability to control the signal, no mechanical jitter, high frequency, no switching wear and other advantages, but also because of these high performance advantages, it makes this kind of automatic control device can be widely used.

As we know, terminal blocks are part of connector devices, but there is a big difference between terminal blocks and connectors in marketing mode. Connector practitioners mainly appear as traders. And wiring terminals mostly appear in the manufacturer's situation. This illustrates the hierarchical difference between connectors and terminal blocks. In terms of technology, the production technology requirements of connector products are high, and the testing environment is harsh. Many businesses cannot meet the production and monitoring requirements of products. Many large connector manufacturers have established networks all over the world, so connector practitioners can spend their time acting as agents, earning commissions and certain rewards without investing too much technical capital. https://www.bossgoo.com/product-detail/longyi-nylon-female-spade-connector-insulated-61372472.html For wiring terminals, the need for a slightly lower technology, but because of the sale of wiring terminals, wiring terminals to manufacturers of the situation, so in the market, wiring terminals are not inferior to connectors. Terminals and connectors have their own industry rules. The sales mode of wiring terminal is mainly manufacturer, connector processing manufacturer/connector trading manufacturer - connector terminal customer, connector sales mode is mainly connector trader - connector manufacturer/connector trader - to connector terminal customer.

Terminal crimping is usually the use of special terminal machine for operation, it has very strict technical standards, mainly including: pull force size, symmetry... And so on. https://www.bossgoo.com/product-detail/insulated-pin-terminals-pin1-25f-terminal-61373688.html A well-crimped terminal can not only ensure the integrity of mechanical strength but also meet the requirements of electronic aspects, the following will be introduced in the form of pictures in general naked eye conditions can be identified by the improper crimping terminal products. If the terminals are not crimped correctly on the cable, you will forget all the hard work that went into selecting the right terminals. While there are common crimping height issues that can reduce the reliability of your product, they can be easily avoided with a little knowledge and foresight. The crimp height is the cross section height of the body crimp area after crimp, and it is the most important feature of good crimp. Terminal manufacturers have increased the crimp height for each cable size designed for the terminal. The correct crimp height range or tolerance for a given cable may be as small as 0.002 ". Under such strict specifications, it is important to verify that the crimp machine is set up correctly to obtain good crimp. If the crimping height is too small or too large, the crimping strength (holding force against the cable terminal) cannot be provided. As a result, the drawing force and rated current of the cable are reduced, and the performance of the crimping terminal is degraded in abnormal working conditions. Too small crimping height can also crush the conductor core or just break the metal in the conductor crimping area.

The copper terminal must withstand the high temperature in the preheating zone and the temperature transmitted to the terminal body by wave soldering during the whole assembly process. Flux must not affect terminals and must be easily removed without any residue. The entire assembly process must be water-washable. Preheating temperatures are often 100°C or higher, and peak temperatures of 280°C are not uncommon. Perforated soldering pins must be accurately positioned, of suitable size, evenly placed, and of good solderability to facilitate insertion and welding. In the whole assembly process must withstand the heat treatment of high temperature impact, in welding mainly used infrared preheating and convection preheating heat conduction to the solder needle and tin plate interface to melt solder paste. Contact anti-fusion welding performance is poor, in the start of the motor or circuit short circuit, large current to contact. The head is welded firmly and cannot be released. The pure silver contact is easier to fuse and weld. The main contact of ac contactor should choose the silver base alloy with strong fusion welding ability, such as silver iron, silver nickel and so on. https://www.bossgoo.com/product-detail/longyi-insulated-copper-terminal-connector-fork-61370833.html The copper terminal has good connection characteristics even when the temperature fluctuates greatly. Because this can avoid different degrees of thermal expansion due to the difference of thermal expansion coefficient of the material, so it can avoid mechanical stress in the terminal, to avoid the loosening of the connection. Use "Reakdyn principle" to prevent terminal screw from loosening. In the preferred terminal series with rated cross sections up to 10mm2, the crimping frame adopts the lifting cylinder structure. Their principle of action is based on the so-called "lifting drum principle". The constant improvement of circuit board technology has greatly increased the amount of current that can be carried by the copper tube terminals mounted on the panel.

The following Jin Longyi Xiaobian to tell you what the terminal line tension standard is, I hope to help you oh. The pulling force data between terminal and wire can ask your supplier for, what the supplier provides is reliable and persuasive. Or you test the standard set by the original manufacturer (MOLEX,JST,AMP). In fact, our company can develop: each terminal model to the sample of 30, or more, of course, the more the better, of course, to meet the terminal pressure high standards, can be tested.

Copper tube terminal production and manufacturing precautions in the scientific research of copper tube terminal quality assurance problems are will take into account the various natural environment it encountered, then, in the design of the terminal will fully consider all raw materials including metal composite materials and raw materials. The raw material will harm the quality of wiring terminals, this problem is all the design staff in the design of copper terminal to take into account. The quality characteristics of the terminal insulation layer shell are as high as the metal structure, the vast majority of the insulation layer shell is made of PA66, PC, PP and other plastic. No matter which kind of raw material, the shell is stipulated to achieve the corresponding fire grade, temperature resistance, environmental protection characteristics, dielectric strength and impact toughness. The key of the brass terminals metal material components of the electrical conductivity, screws and clamping piece, in which the key is the conductivity of the copper content is how much, in the national standard "household and similar use plug socket (GB2099) and the fixed device of the electrical switches for household and similar purposes" (GB16915), clearly stipulates composition of copper is 58% less. Copper has very good metal material laser cutting processing characteristics and high corrosion resistance characteristics; Copper is only second to silver in conductivity. Therefore, copper is particularly suitable for the composition of electrical and mechanical connection components such as terminals. Copper metal products and copper wire have basically the same linear expansion coefficient, to prevent the temperature fluctuation caused by different levels of thermal deformation, so it can prevent the copper tube terminals caused by mechanical equipment stress, prevent the resulting loosening of the connection. Screws and clamping pieces of copper alloy is commonly used in raw materials, or surface plating process antirust treatment of steel raw materials, the key is to have the corrosion features and plenty of impact toughness, under normal circumstances do not apply an surface plating process antirust treatment of steel raw materials, it can prevent the steel metal products and copper wires in a damp condition of rechargeable batteries, To prevent the occurrence of unreliable electrical connection and screw rust caused by electrical erosion. The surface of the general steel component must be plated with nickel, which can have a certain anti-corrosion effect.

The failure rate of terminals increases exponentially with the rise of temperature, and the service life decreases exponentially with the rise of temperature. The service life of terminals will be halved when the ambient temperature increases by 10 ° C. General installation environment requirements for terminals are as follows: Low ambient temperature -5 ° C, high ambient temperature 40 ° C.

Terminal blocks are the most basic items for purchasing personnel working in the electrical field. Because of the function of transmitting signals, any electrical can not do without terminal blocks. The appearance of terminal products can not be described by color, but you can see the shape, color, smoothness and other factors of the appearance. Generally speaking, the terminal shape is regular, no concave and convex plane, no burr is preferred; Color check whether it is the color you need, there is no color difference; Whether the coating of conductive parts is uniform, whether due to the bad storage time or storage environment rust; Terminal needle distance size is consistent with the national standard creepage distance, needle distance is uniform. To smell means to smell. In order to save cost, some businesses will be used for many times to do the production of raw materials to shape the terminal, in order to cover up the taste of the material, add aromatic agent in it, this terminal will smell a light fragrance after getting. Encounter this kind of terminal, should distinguish seriously.

To solve the problem when using the terminal, pay attention to the following phenomena: The first phenomenon: the wiring terminal is not in good contact. The metal conductor inside the wiring terminal is the core part of the terminal. It transfers the voltage, current or signal from the external wire or cable to the contact corresponding to its matching connector. Therefore, the contact must have excellent structure, reliable contact holding force and good electrical conductivity. The second phenomenon: poor insulation of the terminal: the function of the insulator of the terminal is to keep the contacts in the correct position, and to insulate each other between the contacts and the contacts and between the contacts and the shell. Therefore, the insulating parts must have excellent electrical properties, mechanical properties and process forming properties. Especially with the widespread use of high-density and miniaturized terminal blocks, the effective wall thickness of insulators is getting thinner and thinner. Third phenomenon: Poorly fixed terminal block insulators not only insulate, but also usually provide accurate neutralization protection for extended contacts, and also have the function of installation, positioning, locking and fixing to the equipment. Bad fixation, light influence contact reliability resulting in instant power failure, serious is product disintegration.

For threaded terminals, screws, copper posts and platen are important components of the clamping mechanism. For non-threaded terminals, springs or spring cards are important components of the clamping mechanism. No thread terminal, the pressing mechanism is mainly spring, so the selection of spring is very important, both to ensure that there is enough contact pressure, to ensure that the wire will not be too damaged, spring terminal is currently more reliable without thread terminal. When entering the line, you can press the spring by pushing the block or screwdriver, after entering the line, loosen the spring, use the spring back tension to press the wire tightly, produce enough contact pressure, and then use the edge of the spring to choke the wire, so that it will not loose or artificially pull out. During the use of terminal blocks, a large torque is generated to ensure sufficient contact pressure for the wire. As specified in GB2099 and GB16915, tightening or loosening the clamping screw does not cause loosening of the terminal. Threaded terminal, screw self-locking ability to play a decisive factor, the general principle of terminal screw self-locking is based on the "lifting cylinder principle". When tightening the screw, the screw tightening force does not directly act on the wire, but on the clamping part. The resulting automatic step self-locking makes the screw friction gradually increase, realizes the screw self-locking, and finally clamps the wire on the conductive strip. There are different torque requirements for different thread diameters, such as M3 pressure screw, requiring a torque of 80N will not cause damage to the terminal. There is no air gap in the column of wiring terminal magnetic system, and the remanence is too large. Part of the pole surface at the remanent magnetic gap is filed away to make the gap 0.1-0.3mm, or a 0.1uF capacitor is connected in parallel at the two ends of the coil. The surface of the contactor core is oily or greasy after a period of use. Wipe the rust proof grease on the surface of the iron core. The surface of the iron core should be smooth, but it should not be too bright, otherwise it is easy to cause delayed release. During the entire assembly process, it must withstand the high temperature of the preheating zone and the temperature transmitted to the terminal body by wave soldering. Flux must not affect terminals and must be easily removed without any residue. The entire assembly process must be water-washable.

The working characteristic of conductor terminals is to connect and conduct electricity, so the material of the terminals should also meet its working conditions. Conductivity is one of the best gold, silver, copper, the former two cost is too high, pure copper relative cost is low, can satisfy its technical requirements, so now the conductor terminal are mostly choose pure copper stainless steel because joined the chromium, niobium, nickel alloy elements, such as increased resistance to electric conductivity drops greatly, not suitable for used as conductor terminal wire terminals of hardness shoulds not be too big, Hardness is too large combination is not good, the effective contact surface of the terminal will become smaller, the cross-sectional area of the conduction current will be limited, this is why to hang tin on the terminal surface, tin hardness is soft, can make the terminal surface fully combined.

We need to pay attention to when using Insulated Terminals several advisory principles, according to the different aspects of these can be better to use, as a user for these different aspects are the principle on the need knowledge, in order to we can more rational in using the above to operate it is necessary, In the use of the principle of insulation terminal above has the following points related to the introduction: 1, our choice of terminals must be authentic, above the use of the overall need to use safe products that meet the national standard is necessary, for these different manufacturer's product is we try to choose standard GB14048.7/8 such a product, for different standards on the terminal itself makes the function is different also, Try to be considerate in your choices. 2, the product material is an important factor directly affects the performance of the product, at the time of use need to relative specifications according to their own needs to consider, the insulation of the terminal on the market most of the material is plastic or plastic material, for different material makes itself the above related performance has a certain influence, It is necessary for us to have a corresponding understanding so as to be able to use it more reasonably in the overall operation. Try not to choose second-hand products in the use of products. There are certain hidden dangers in the use of products. 3, due to the Insulated Terminals itself above parts also determines its function, the material we is necessary for it to have a choice, a good material can provide a great help to its function, and determines whether it can at the time of environment can be safe, it is necessary to for us to use, We need to make relevant judgments according to the elasticity and hardness of the relevant accessories, so that it can effectively improve its function. When we use insulation terminals, we can help us to use such products more effectively. Above 4, due to the outside of the terminal plating film is decided the product life one of the factors above, we are in for the use of such a product when it is necessary to use more solid, it plating film can be somewhat isolated from the rest of the world conditions make use of time can be longer and more stable, It can be used effectively for general environmental conditions. 5, the structure of the product itself above the different to its function will also have an effect, is necessary before using the terminal to its own to realize the above structure, the different materials and related to its above the function structure of the above will have relations, we are in the process of use of such products to its different structures above above should have certain judgement, This can improve its performance to some extent.
