Evaluating the reliability of connecting wires requires testing and validation from multiple aspects. The following is an evaluation method compiled based on the latest information

：

1. Insertion and extraction force test

Purpose: To verify whether the insertion and extraction force of the connecting wire meets the product specification requirements.

Method: Fully insert or remove the connecting wire at the specified speed, and record the corresponding force value.

Reference standard: EIA-364-13.

2. Durability testing

Purpose: To evaluate the impact of repeated plugging and unplugging on connecting wires and simulate the plugging and unplugging conditions in actual use.

Method: Plug and unplug the connection cable continuously at the specified rate until the specified number of times is reached.

Reference standard: EIA-364-09.

3. Insulation resistance test

Purpose: To verify whether the insulation performance of the connecting wire meets the requirements of the circuit design, especially whether its resistance value meets the technical conditions under high temperature, humidity and other environmental stresses.

Method: Apply voltage to the insulation part of the connecting wire, measure the leakage current generated on the surface or inside of the insulation part, and obtain the resistance value.

Reference standard: EIA-364-21.

4. Voltage endurance test

Purpose: To verify whether the connecting wire can work safely under rated voltage, whether it can withstand overpotential, and thus evaluate whether the insulation material or insulation gap of the connecting wire is suitable.

Method: Apply a specified voltage between the connecting wire contacts and between the contacts and the housing, and maintain it for a specified time to observe whether the sample has breakdown or discharge phenomena.

Reference standard: EIA-364-20.

5. Contact resistance test

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

Method: By passing a specified current through the connecting wire and measuring the voltage drop at both ends of the wire, the resistance value can be obtained.

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

6. Vibration testing

Purpose: To verify the effect of vibration on the performance of connecting wires and their components.

Method: Apply random vibration or sine vibration to the connecting wire and evaluate its performance changes under vibration conditions.

Reference standard: EIA-364-28.

7. Mechanical impact test

Purpose: To verify the impact resistance of the connecting wire and its components, and evaluate whether their structure is firm.

Method: Apply a specified shock waveform (such as half sine wave, square wave) to the connecting wire and record the tolerance of the connecting wire.

Reference standard: EIA-364-27.

8. Environmental adaptability testing
