With the rapid development of the automotive industry, various functional parts and various components on automobiles are continuously developing in the direction of intelligence, refinement and reliability. The structural design, appearance design and materials of automotive connectors have also been proposed. higher requirement.

Automotive connectors must meet the USCAR-20 standard, which is the performance standard for automotive electrical connector systems. It requires that the electrical connector contact surface of the automotive connector be reliable throughout the entire life cycle, including the following factors:

First, the material of the connector contacts is stable and reliable

2. Stable forward force

Three, the voltage and current of the circuit are stable

Fourth, the temperature requirements are within the specified range, including the surrounding temperature and its own temperature rise

5. Better robustness

6. It must be the same as the connector for high-speed long-distance communication computer. The automotive connector must be able to work reliably under harsh conditions.

Connector insertion force: below 20.5kg;

8. Connector holding force: 2.5kg or more;

9. Heat resistance: -40 ~ 120 ℃
