Contact resistance will affect the service life of car connectors, so today we are going to look at what factors can affect the contact resistance of the automotive connector terminal. 1. Influence of terminal materials Different terminal materials have different hardness and conductivity. According to the analysis of action principle of contact resistance, different hardness results in different actual contact areas of each contact point on the terminal contact interface, thus resulting in the different actual total contact areas of terminal contact interface. The effect of the actual contact area on the additional resistance at the contact interface is equivalent to the effect of the conductor sectional area on the conductor resistance. Therefore, the additional resistance of terminal contact interface will be influenced by different hardness of terminal materials. To go further, different conductivity directly affects the resistance of the terminal contact area. When it comes to automotive connector terminal options, materials with appropriate conductivity and hardness should be selected in accordance with the design targets. Meanwhile, the material with stable electrical conductivity and mechanical properties is worth considering to ensure the stability of contact resistance. 2. Influence of terminal contact interface geometric shape The effect of terminal contact interface geometric shape on contact resistance is mainly due to the fact that different geometric shapes will form different macroscopic contact areas. The difference of macroscopic contact areas results in different number of contact points, which causes the difference of the actual contact area. In practice, different contact interface geometric shapes should be selected according to different requirements. The line contact and surface contact will be affected by the terminal specification and shape, forming different macroscopic contact areas. 3. Influence of terminal positive force Terminal positive force refers to the force generated from the contact surface between the male and the female terminals and the force perpendicular to the contact surface at the same time. With the increase of terminal positive force, the actual contact point amount and area of terminal contact interface also increase gradually, according to the analysis of action principle of contact resistance. Therefore, the actual contact area increases with the increase of positive force. 4. Influence of terminal contact interface surface state The influence of contact interface surface state of the automotive connector terminal on contact resistance is mainly manifested in the influence of surface roughness and oxidation film condition at the contact interface on contact resistance. The roughness of contact interface has an effect on contact resistance, mainly because the difference in roughness will lead to the different amount of microscopic contact points at the contact interface and ultimately affects the size of contact resistance. The surface oxide film at the contact interface is produced by the contact between the contact interface and the atmosphere. Chemical and electrical corrosion during use will make the situation worse. The thickness and the state of the surface oxide film determine the size of the film resistance. Therefore, the surface oxide film at the contact interface has a certain influence on the contact resistance.

1. Application of automobile nylon cable ties With the rapid development of the automobile industry, the speed of automobile production is very alarming. Generally, there are many automobile wiring harnesses in the interior of the car. The automobile wiring harness is equivalent to the neural network of the automobile used to convey various instruction information and telecommunication signals, so that the whole vehicle is in a better control and running state. However, the existing automobile wiring harnesses are scattered in the interior of the automobile, and it is difficult to assemble the scattered wiring harnesses together, but the stability after assembly is not high and it is prone to failure. 2. The use of car nylon cable ties These wiring harnesses are fixed on the automobile sheet metal by auto harness, and the safety and reliability of the wiring harness fixing is very important to the electrical safety of the whole vehicle. With the increase of vehicle engine functions, the wiring in the car cab and the engine need to communicate in real time, and more and more wiring harnesses need to be connected to the engine. The engine is a vibrating part, and the vehicle body also vibrates, so the wiring harness arranged on the car will also vibrate, which requires special attention by nylon cable tie manufacturer. Therefore, the fixing stability of the wire harness depends not only on the ability of the wire tie to fix the wire harness, but also on the stability of the wire tie on the vehicle body. However, the connection structure of the traditional automobile wire harness tie and the body is too simple, and the tie is easy to loosen, which causes the wiring harness and the nylon cable tie to shake as a whole, which seriously affects the stability of the wiring harness fixing. In response to the above-mentioned shortcomings, a new type of automotive wire tie has been developed, which not only improves the stability of the wire tie on the car body, but also has no looseness between the wire tie and the car body, reducing the sway of the wire tie relative to the car body, ensuring the stability of the wiring harness, and improving the flexibility of the connection.

Generally, there are corrugated pipes, PVC tubes, sponges, tapes, etc. on the outside of automobile wiring harnesses for wrapping and protection. For the entire automobile wiring harness assembly, different types of via rubber parts, cable ties, wiring harness buckles, wiring harness brackets and tapes are needed to limit the relative position of wiring harness products. Since automotive wiring harness products are generally supplied to the automaker in the form of assembly supply, this article mainly introduces fixed protection parts from the perspective of fixed protection of automotive wiring harnesses. The following is various types of automotive cable ties and their use environment and application examples. 1. Ordinary plastic cable tie According to different structures, there are two types: one-piece type and split type with movable fixed end. Ordinary cable ties are used in places where the wiring harness and pipeline have no specific location requirements relative to the vehicle and the space is relatively open. If you want to limit the position of the wire harness assembly, you need to use it with a fixed bracket or with various types of cable tie connectors. 2. Screw-fixed plastic cable tie This type of cable tie is mainly used in areas where holes cannot be opened to strictly prevent rain, dust, etc. from entering the passenger compartment. Used in conjunction with bolts or screws, the general specification of screws is M5~M8. 3. Arrowhead mount cable tie for round hole This type of cable tie is used with round holes. The hole diameter is generally φ5~φ8 mm. The disk at the end of the arrow can play a role in dust prevention. Arrow ties can only be used for single-layer boards, and the board thickness is usually less than 3 mm, which is different from the elliptical hole fixed plastic ties. This type of plastic ties allows the wire harness to be twisted after installation, and is mostly used for flat metal sheets, and used in places where the wiring space is large and the wiring harness direction is relatively gentle. 4. Arrowhead mount cable tie for oval hole This type of plastic cable tie can prevent the wire bundle from twisting after the installation is completed. It has a better effect on the environment where the direction of the wire harness needs to be strictly limited, and has a strong fixing stability after the installation is completed.

In a complete set of automotive wiring harnesses, there are generally more than a thousand parts, and the car cable tie is one of the most inconspicuous parts among the thousand. Regarding automotive wiring harness ties, many people can't help but think that this small product is not worth talking about. Some people even think that the integration of electronic products is becoming more and more advanced, and automotive wiring harness ties are optional! This view is inevitably biased. In fact, in developed countries such as Europe, America and Japan, there are many large enterprises specializing in the production and research and development of various wire harness ties. At present, there is a dedicated wire harness and tie department, which specializes in the production and sales of such fastener products, which are widely used in aviation, automobiles, electronics, networks, electrical, military, toys and other industries. It can be seen that wire cable ties are still essential and important products in industrial production. 1. The importance of automotive wiring harness cable ties Although the product of automotive wiring harness tie is small, its importance cannot be ignored. The main function of the wire tie is to integrate, fix and arrange the wire harness. The quality of automobile wiring harness straps is not good, and they become loose or broken during use. In the slightest, the wiring harness is entangled, which affects the appearance and product image. In the worst case, the circuit is short-circuited and fires, the aircraft falls to the ground, and the car is destroyed. Therefore, those cable tie manufacturers that attach importance to product quality tend to be very rigorous in the selection of wire ties. 2. The choice of material for automotive wiring harness ties When selecting automobile wire harness ties, the application should be considered first, mainly due to factors such as temperature and light. The wire ties of general cable tie companies use nylon as the raw material, which has the characteristics of large applicable temperature range and corrosion resistance. Nylon cable ties has the characteristics of fast lashing, good insulation, self-locking forbidden, convenient use, etc., and different ingredients are added in the production process to make the product suitable for different occasions. In places where the temperature of the car is not high, such as inside the car, we can choose the general cable tie of -40-85℃. However, in the engine compartment, there are certain temperature requirements for the cable tie of the wire harness. Generally, we choose the cable tie of -40-105°C. At this time, it is necessary to add heat-resistant materials.

Automotive connectors are an indispensable and particularly important part of both traditional and new energy vehicles. This is because the entire interior of the car plays a relevant and important role. So let's talk about the role and performance of automotive connectors. 1. Car connector plays a role in ensuring car safety For automotive connectors, since many parts are related to safety, it is very important to select automotive connectors. Among those different car connector types, the part of the connector near the engine should have a temperature resistance of 150℃ or higher, and the other connectors should withstand a temperature of 105℃ or 85℃. Therefore, the temperature resistance of car connectors is higher than that of ordinary connectors. 2. The performance of the car connector during use The harsh environment of the car during driving will affect the use of the product. For example, the line is short-circuited after the car is washed, or the camera is blurred, etc. This is because the connector is not waterproof. In order to avoid the impact on safety and performance, the waterproof of the car connector is another important performance, which means waterproof automotive connectors are required. Between the male connector and the device, between the female connector and the cable, between the male connector and the cable, and between the female connector and the cable, the four types of connections need to be waterproofed. The international automotive connector waterproof standard is IP67, which is also the industry's waterproof standard. According to different car parts, there will be different waterproof requirements. There are three main types of waterproofing for automotive connectors: (1) Structural waterproofing; (2)Sealing ring (silicone ring) for waterproofing; (3) Use waterproof glue for waterproofing. In order to ensure that the electronic circuit technology can work better, car connectors are generally designed for shielding. The function of shielding can firstly protect the electronic circuit of the car, and secondly, it also has the effect of anti-interference and radiation on other parts. The shielding technology is divided into two types: inner shielding and outer shielding. The inner shield is to shield the influence of the radiation generated by itself on other parts; while the outer shield is to prevent the radiation interference of other parts from affecting its performance.

1. Types of automotive wiring harness terminal According to the shape, the terminals can be divided into slice series, cylindrical series, and wire connector series. 1) The slice series terminals are made of H65Y or H70Y material, and the material thickness is 0.3-0.5. 2) Cylindrical series terminals are made of H65Y or Qsn6.5-0.1 material, and the material thickness is 0.3-0.4. 3) Wire automotive connector terminals are divided into three types: U-shaped, fork-shaped and hole-shaped. ① The U-shaped terminal is made of H62Y2, H65Y, H68Y or Qsn6.5-0.1 material, and the material thickness is 0.4~0.6; ②Fork-shaped terminals are also called Y-type terminals. Y-type terminals are made of H62Y2 with a thickness of 0.4-0.6. Part of the surface is nickel-plated with good conductivity; ③ Hole terminals generally use H65Y and H65Y2 as the base material, and the material thickness is 0.5 to 1.0. 2. Selection principle of automotive wiring harness terminal It needs to choose terminals with different coatings according to different connectors and different needs. For equipment that requires high performance, such as airbags, ABS, car ECU connector, terminals should be gold-plated to ensure safety and reliability. However, for cost considerations, partial gold-plating can be selected on the premise of meeting performance requirements. The specific selection principles are: ① Ensure that the terminals are reasonably matched with the selected connectors. ②Choose the appropriate terminal for the wire diameter of the crimped wire. ③For single-hole waterproof connectors, choose a terminal whose tail can crimp the waterproof plug. ④Ensure the reliability of the connection. When selecting automobile wiring harness terminals, ensure good contact with electrical components and plug-ins, so as to minimize contact resistance and improve reliability. For example, surface contact is better than point contact, and pinhole type is better than leaf spring type. In the design, the connector with double spring compression structure (with very low contact resistance) should be preferred. ⑤ Impedance matching. Some signals have impedance matching requirements, especially radio frequency signals, which have stricter requirements for impedance matching. When the impedance is not matched, signal reflection will be caused, which will affect signal transmission. Therefore, when selecting automotive wiring harness terminals, you must choose impedance-matched terminals.

Automotive wiring harness connectors are used to connect the connection points of automotive circuits, which are important parts of automobiles. Their quality directly affects the transmission effect of power or signals. Connectors account for a small proportion of the cost in automobiles, but if quality problems occur in automobile use, serious consequences will often occur, and maintenance costs will increase significantly. Therefore, the quality of connectors requires more attention by automobile manufacturers and auto parts suppliers. 1. The invalidation of automotive wiring harness connector terminal The pin retraction of automotive wiring harness connector terminal is a relatively common failure form of automotive wiring harness connectors. It means that after the connector is assembled, the terminal and the sheath are abnormally separated, thereby causing the connector to lose its function. The reasons for this failure form generally include three aspects: ①The retention of the terminal in the sheath is unqualified; ②Interference in terminal of plug-in connectors; ③Product application problems. According to these three reasons, automotive connector supplier LR analyzes the pin withdrawal of the connector terminal and proposes a solution. 2. Analysis of the causes of pin retraction of automotive wiring harness connector terminals (1) The retention of the terminal in the sheath is unqualified The retention of the terminal in the sheath refers to the force required to separate the terminal from the sheath in the axial direction. In order to avoid the phenomenon of terminal withdrawal, the performance test standard of the connector sets strict regulations on the retention force of the terminal in the sheath: ①The retention of the connector with a specification not greater than 2.8 is greater than 40N; ②The retention of connector with a specification greater than 2.8 is greater than 60N. In practice, most of the phenomenon of terminal withdrawal is because the retention does not meet the requirements. Generally speaking, the reasons for the unqualified retention of the terminal in the sheath are: structural design problems; material selection problems. (2) Interference in terminal of plug-in connectors Interference in terminal of plug-in connectors means that the male terminal and the female terminal of the connector are inserted into the ineffective area of the female terminal during the mating process, so that the connector has a failure form such as terminal withdrawal. Generally speaking, the reasons for this are: ①Structural design problem; ②Terminal insertion force problem. (3) Product application The product application related to the return of connector terminals mainly refer to the problem that may cause the withdrawal of the terminals during the wiring harness production process. Generally include terminal crimping problems and terminal assembly problems. It is mainly caused by improper use method during product use. After adjusting the terminal crimping, this problem can be solved. Related Blogs A Carefully Made Car Cable Tie What Capabilities Should an Automotive Connector Manufacturer Have?

The fixed design of automobile wiring harness is a very important item in the design of wiring harness layout, and its main forms are auto cable ties, buckles, and brackets. Ⅰ. The role of automotive cable ties Automotive cable ties are the most used wire harness fixing and protective materials, mainly made of PA66. Most of the fixing of automobile wire harnesses is done with cable ties. The function of the automotive cable tie is to fasten the wire harness and make it firmly and reliably fixed on the body sheet metal holes, bolts, steel plates and other parts to prevent the wire harness from vibration, displacement or interference with other parts and damage the wire harness. Ⅱ. The classification of automotive cable ties Although there are many types of cable ties, they can be divided into the following types according to the type of sheet metal: card round hole type cable tie, card waist round hole type cable tie, card bolt type cable tie, card steel plate type cable tie, etc. 1. The round hole type cable tie is mostly used in places where the sheet metal is relatively flat and the wiring space is large and the wiring harness is smoothly routed, such as the cab, the diameter of the round hole is generally 5-8 mm. The card-waist round-hole cable tie is mostly used for the thick trunk or branch of the wire harness. After installation, this cable tie cannot be rotated at will, and has strong fixed stability. It is mostly used in the front compartment. The aperture is generally 12×6 mm, 12× 7 mm) 2. Bolt-type cable ties are mostly used in places where the sheet metal is thick or where the uneven wiring harnesses are irregular, such as firewalls. The apertures are generally 5mm or 6 mm. 3. The steel plate type cable tie is mainly used on the edge of the steel sheet metal to jam the sheet metal, so that the wire harness transitions smoothly, and at the same time, to prevent the sheet metal edge from piercing the wire harness.
