The specific test items of the connector are as follows:

1. Connector plugging force test

Reference standard: EIA-364-13

Purpose: To verify whether the plug-in force of the connector meets the requirements of product specifications.

Principle: fully insert or pull out the connector at the specified rate, and record the corresponding force value.

2. Connector durability test

Reference standard: EIA-364-09

Purpose: To evaluate the impact of repeated plugging on the connector and simulate the plugging condition of the connector in practical use.

Principle: continuously plug and unplug the connector at the specified rate until the specified number of times is reached.

3. Connector insulation resistance test

Reference standard: EIA-364-21

Purpose: To verify whether the insulation performance of the connector meets the requirements of circuit design or whether the resistance value meets the provisions of relevant technical conditions when it is subjected to environmental stress such as high temperature and humidity.

Principle: apply voltage to the insulating part of the connector to generate leakage current on the surface or inside of the insulating part.

4. Connector withstand voltage test

Reference standard: EIA-364-20

Purpose: To verify whether the connector can work safely under rated voltage and withstand overvoltage, so as to evaluate whether the insulation material or insulation gap of the connector is appropriate.

Principle: apply the specified voltage between the connector contact and the contact, and between the contact and the shell for the specified time, and observe whether the sample has breakdown or discharge.

5. Connector contact resistance test

Reference standard: EIA-364-06 / EIA-364-23

Purpose: To verify the resistance value generated when the current flows through the contact surface of the contact.

Principle: measure the voltage drop at both ends of the connector by applying the specified current to the connector, so as to obtain the resistance value.

6. Connector vibration test

Reference standard: EIA-364-28

Purpose: To verify the effect of vibration on the performance of the electrical connector and its components.

Vibration type: random vibration, sinusoidal vibration.
