New energy electric vehicle connector performance

With the development of the new energy electric vehicle industry in recent years, connectors, as important parts of energy storage systems and new energy vehicles, have ushered in a golden period of development. If you want to know the basic performance of the new energy connector, you can continue to read this article, and Elecbee electronics engineer will introduce you the relevant knowledge.

Mechanical properties

As far as the connection function is concerned, the mechanical performance of the connector is the important mechanical performance. Insertion and extraction force is divided into insertion force and extraction force. From the perspective of use, the insertion force should be small, resulting in a structure with low insertion force and no insertion force. If the separation force is too small, it will affect the reliability of contact. The influencing factors of the plugging force and mechanical life of the connector are related to the coating of the contact part, that is, the mass sliding friction coefficient and the dimensional accuracy of the contact part arrangement.

Electrical performance

1.Electrical connectors with high-quality contact resistance should have low and stable contact resistance.

2.Insulation resistance is an index to measure the insulation performance between the contacts of electrical connectors and between the contacts and the shell.

3.Dielectric strength, or withstand voltage, dielectric withstand voltage, is the ability to withstand the rated test voltage between the connector contacts or between the contacts and the shell.

Environmental performance

The environmental performance of the connector is affected by factors such as temperature, humidity, salt spray, vibration and shock, and other air, liquid, and air pressure.

The basic performance of the connector can be divided into three categories: mechanical performance, electrical performance and environmental performance. Another important mechanical property is the mechanical life of the connector. Mechanical life is actually an indicator of durability. It takes one engagement and separation as a cycle, and judges whether the connector can normally complete its connection function after the specified engagement and separation cycle.
