Connector is a device connecting two active devices to transmit current or signal. It is also called connector and socket in China, which generally refers to electrical connector. So what should connector design meet?

1. Connector insertion force: below 20.5kg;

2. Connector retention force: more than 2.5kg;

3. Heat resistance: - 40 ~ 120 ℃

4. The contact material of connector is stable and reliable.

5. The positive force is stable.

6. The voltage and current of the circuit are stable.

7. The temperature should be within the specified range, including the surrounding temperature and its own temperature rise.

8. Good robustness.

9. It must be the same as the connector used in high-speed long-distance communication computer, and the automobile connector must be able to work reliably under harsh conditions.

There are different classifications of connectors. According to the frequency, there are high-frequency connector and low-frequency connector; according to the shape, there are circular connector and rectangular connector; according to the purpose, there are PCB connector, cabinet connector, audio equipment connector, power connector, special purpose connector, etc.
