How to choose terminal material?
When selecting a terminal material, the following characteristics should be considered: ① Mechanical properties of materials. Strength, ductility, yield strength, hardness, etc. ②Electrical conductivity and thermal conductivity of the material. The electrical conductivity is directly proportional to the thermal conductivity, the thermal conductivity is related to the electrical conductivity of the terminal and its own […]
What is the difference between different plating materials of terminals？
Electroplating on the surface of the terminal is a technical method to solve the oxidation and corrosion of the metal on the surface of the terminal, enhance the conductivity of the terminal, and reduce the contact resistance. Besides gold, silver, and nickel or chrome plating, tin plating is most commonly used in terminal plating. Gold […]
Effect of Crimp Height on Mechanical Properties of Terminals
The tensile strength of the terminal mainly depends on the contact pressure between the terminal and the wire. The contact pressure is mainly provided by the elastic deformation and plastic deformation of the terminal and the wire. An important factor that determines the elastic deformation and plastic deformation of the terminal and the wire is […]
Environmental Performance of Connectors
① Temperature resistance: At present, the maximum working temperature of the connector is 200°C (except for a few high-temperature special connectors), and the minimum temperature is -65°C. When the connector is working, the current generates heat at the contact point, causing the temperature to rise. Therefore, it is generally believed that the working temperature should […]

Electrical performance of the connector
The main electrical properties of connectors include contact resistance, insulation resistance and electric strength. ① Contact resistance: High-quality electrical connectors should have low and stable contact resistance. The contact resistance of the connector ranges from a few milliohms to tens of milliohms. ②Insulation resistance: It is an index to measure the insulation performance between the […]
Mechanical Properties of Connectors
As far as the connection function is concerned, the mating force is an important mechanical property. The insertion force is divided into insertion force and pull-out force (pull-out force is also called separation force), and their requirements are different. There are regulations on the maximum insertion force and the minimum separation force in the relevant […]
What is the significance of the existence of the connector?
Imagine what it would be like without the connector. At this point, the circuits should be permanently connected together with continuous conductors. For example, if you want to connect an electronic device to a power source, the ends of the connecting wire must have some method (such as soldering) to hold the electronic device and […]
Factors that affect wire resistance are as follows
1. Temperature The effect of temperature on various materials is different. For example, the electrical resistance of copper and steel increases with temperature. For some materials, the resistance of the material decreases with temperature. When conducting wire resistance measurements, we need to disconnect the wire under test from the circuit. 2. Cross-sectional area The larger […]
The standard of Cat8 network cable
In the field of ethernet communication, when it comes to ethernet cables, it is often mentioned that the Cat5e ethernet cables, the Cat6 ethernet cables and the seven types of ethernet cables are mentioned. However, in recent years, Cat8 cables have begun to be mentioned more, so what is the difference between Cat8 ethernet cables […]
