The connector test generally involves the following items: insertion  force test, durability test, insulation resistance test, withstand  voltage test, vibration test, mechanical impact test, hot and cold  impact test, mixed gas corrosion test

Connector specific test items are as follows:

(A) insertion force test

Reference standard: EIA-364-13

Purpose: Verify that the insertion force of the connector complies with the product specifications

Principle: the connector at a specified rate of complete insertion or removal, record the corresponding force value

(2) durability test

Reference standard: EIA-364-09

Objective: To evaluate the effect of repeated insertion and tear on  the connector, to simulate the actual use of the connector in the plug

Principle: According to the required rate of continuous connection of the connector until the required number of times.

(C) insulation resistance test

Reference standard: EIA-364-21

Purpose: To verify that the insulation performance of the connector  conforms to the requirements of the circuit design or subjected to  environmental stress such as high temperature and humidity, whether the  resistance meets the relevant technical conditions.

Principle: Apply a voltage to the insulating part of the connector so  that the leakage current is generated on the surface or inside of the  insulating part.
The same time as the above-
   (D) withstand voltage test

Reference standard: EIA-364-20

Purpose:  To verify that the connector is able to operate safely at rated voltage  and to withstand the ability to withstand potentials to assess the  suitability of the connector insulation or insulation gap: Between the  connector contacts and the contacts, Apply a specified voltage between the shell and maintain a specified  time to observe whether the sample breakdown or discharge phenomenon.

(5) contact resistance test

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

Purpose: To verify the resistance of the current flowing through the  contact surface of the contact. Principle: By setting the current  through the connector, measure the voltage drop across the connector to  derive the resistance

(6) vibration test:

Reference standard: EIA-364-28

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

Vibration type: random vibration, sinusoidal vibration

(7) mechanical impact test

Reference standard: EIA-364-27

Purpose: To verify the ability of the connector and its components to  withstand impact or to determine whether the structure is secure

Test waveform: half sine wave, square wave

(8) hot and cold impact test

Reference standard: EIA-364-32

OBJECTIVE: To evaluate the effect of the connector on its functional quality under rapid temperature variation

(Nine) temperature and humidity combined cycle test

Reference standard: EIA-364-31

OBJECTIVE: To evaluate the effect of the connector on the performance  of the connector after storage in a high temperature and high humidity  environment

(10) high temperature test

Reference standard: EIA-364-17

Purpose: To assess whether the performance of the terminals and  insulators changes after a specified period of time in a high  temperature environment

(Eleven) salt spray test

Reference standard: EIA-364-26

Objective: To evaluate the corrosion resistance of connectors, terminals and coatings

(12) mixed gas corrosion test

Reference standard: EIA-364-65

OBJECTIVE: To evaluate the corrosion resistance of connectors exposed  to different concentrations of mixed gases and their effects

(13) wire swing test

Reference standard: EIA-364-41
