Material, performance and structural requirements of contact parts

The author of this article has been committed to research on high -pressure connectors in new energy vehicles. In R & D, not only should we avoid similar patents, but also to find suitable parts. And the core structure is its contact parts, for them, especially the structure, performance, and material of its jack, which has a significant impact on the corresponding performance.

The structure of the contact part

In general, the structure of new energy vehicles is not complicated. Basically, the circular connector with metal shells is basically used. With the development of various engineering materials in recent years, plastic connectors are also common. However, its basic structure is basically the same, and generally includes two parts: pins and jacks, which are connected by insertion. In order to pursue its connection performance, generally used pins are basically adopted rigid pins and elastic jacks. Of course, for some contacts with special needs, plating is also required, and silver plated or gold -plated.

The performance of the electric connector contact part

Basic properties are electrical, machinery, and environmental resistance. The former must meet the three aspects of contact resistance, insulation resistance, and insulation resistance. This is also the guarantee of the reliable transmission of light and electrical signals. In terms of machinery, it is necessary to consider the factors of plug -in and mechanical life. Most of the overall life span of this type of component is inserted 50 times.

Materials of Electric Connectors

The selection of pins and jack materials must first ensure that it has a high mechanical strength. Secondly, in order to prevent damage and loosening; the contact force must be strong, and the jack material also needs to ensure that it has high elasticity. The anti -fatigue resistance of the two and the performance of processing and molding require a certain guarantee. Most of the pins materials selected at present are brass.
