Connector reliability testing items and testing standards

Connector reliability testing items and testing standards

Connector testing generally involves the following items: insertion and extraction force test, durability test, insulation resistance test, vibration test, mechanical impact test, cold and hot impact test, mixed gas corrosion test, etc.

The specific testing items for connectors are as follows:

(1) Connector insertion and extraction force test

Reference standard: EIA-364-13

Purpose: To verify whether the insertion and extraction force of the connector meets the product specifications.

Principle: The connector is fully inserted or pulled out at the specified rate, and the corresponding force value is recorded.

(2) Connector durability test

Reference standard: EIA-364-09

Purpose: To evaluate the impact of repeated insertion and removal on connectors and simulate the actual insertion and removal of connectors in use.

Principle: Continuously plug and unplug connectors 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 circuit design requirements or whether its resistance value meets relevant technical conditions when withstanding environmental stresses such as high temperature and humidity.

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

（4） Connector voltage test

Reference standard: EIA-364-20

Purpose: To verify whether the connector can work safely at rated voltage and withstand overvoltage, in order to evaluate whether the insulation material or gap of the connector is suitable.

Principle: Apply a specified voltage between the connector contactor and the contactor, and maintain it for a specified time to observe whether the sample has been broken down or discharged.

（5） Connector contact resistance test

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

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

Principle: By measuring the voltage drop at both ends of the connector, the resistance value is obtained.

(6) Connector vibration test

Reference standard: EIA-364-28

Purpose: To verify the impact of vibration on the performance of electrical connectors and their components.

Vibration type: random vibration, sinusoidal vibration.

(7) Connector mechanical impact test

Reference standard: EIA-364-27

Purpose: To verify the impact resistance of connectors and their components or evaluate their structural stability.

Test waveform: half sine wave, square wave.

（8） Cold and hot impact test

Reference standard: EIA-364-32

Purpose: To evaluate the impact of connectors on their functional quality under rapid temperature difference changes.

（9） Connector temperature and humidity combination cycle test

Reference standard: EIA-364-31

Purpose: To evaluate the impact of connectors stored in high temperature and humidity environments on their performance.

（10） High temperature testing of connectors

Reference standard: EIA-364-17

Purpose: To evaluate whether the performance of terminals and insulators has changed after being exposed to high temperature environments for a specified period of time.

(11) Connector salt spray test

Reference standard: EIA-364-26

Purpose: To evaluate the salt spray corrosion resistance of connectors, terminals, and coatings.

（12） Connector mixed gas corrosion test

Reference standard: EIA-364-65

Purpose: To evaluate the corrosion resistance and performance of connectors exposed to different concentrations of mixed gases.

（13） Connector wire sway test
