With the rapid advancement of the automotive industry, various functional components and parts within vehicles are continuously evolving toward greater intelligence, precision, and reliability. Consequently, this trend imposes increasingly stringent requirements on the structural design, aesthetic design, and material selection of automotive connectors.
Automotive connectors must comply with the USCAR-20 standard-a performance benchmark for automotive electrical connector systems. This standard mandates that the contact interfaces of automotive connectors remain consistently reliable throughout their entire service life, encompassing the following key factors:
- Stable and reliable materials for the connector contacts;
- Stable contact normal force;
- Stable circuit voltage and current;
- Temperature requirements maintained within a specified range, accounting for both ambient temperature and the connector's own temperature rise;
- Superior robustness;
- A standard equivalent to that of connectors used in high-speed, long-distance data communication systems; specifically, automotive connectors must be capable of operating reliably under harsh environmental conditions;
- Connector Insertion Force: Less than 20.5 kg;
- Connector Retention Force: Greater than 2.5 kg;
- Heat Resistance: -40°C to 120°C.
