The material, performance and structural requirements of the contact

In the relevant aspects of the energy storage connector of new energy vehicles, it is necessary not only to avoid similar patents, but also to find suitable components, and the most core structure is the contact. For them, especially the structure, performance and material of the jack have a significant impact on the corresponding performance.

The structure of the contact

The overall structure of the energy storage connector of new energy vehicles is not complicated, and basically all circular connectors with metal shells are used. With the development of various engineering materials in recent years, plastic connectors are also more common. But the basic structure is basically the same, generally including two parts, pins and sockets, and the connection is achieved by plugging. In order to pursue its connection performance, the commonly used pins are basically rigid pins and flexible sockets. Of course, for some contacts with special needs, electroplating is required, mostly silver or gold plating.

Performance of electrical connector contacts

The basic performance includes three aspects: electrical, mechanical, and environmental resistance. The former is to meet the requirements of contact resistance, insulation withstand voltage, and insulation resistance, and the latter is to ensure the reliable transmission of optical and electrical signals. Mechanically, factors such as plug-in force and mechanical life need to be considered. The overall life of this type of component is mostly more than 50 times the number of plug-in and pull-out times.

Material of electrical connector contacts

The materials of pins and sockets should have high mechanical strength and elasticity to prevent damage and loosening, have strong contact force, fatigue resistance, and guaranteed processing and molding capabilities. Brass is generally used as the material of the pin.
