      Electronic connector reliability test and test method thereof

      source:YUAN TAI ELECTRICAL CO .,LTDrelease time:2018.10.17 17:17:26 attention:1,578

      In a variety of military aircraft and weaponry, the amount of electrical connectors is large, especially the amount of electrical connectors used on aircraft is extremely large. Generally speaking, the use of an aircraft electrical connector can reach hundreds to thousands of pieces, involving tens of thousands of lines. Therefore, in addition to meeting the general performance requirements of the electrical connector, a particularly important requirement is that the electrical connector must have good contact, reliable operation, convenient maintenance, and reliable operation of the aircraft circuit directly affects the normal operation of the aircraft circuit, involving the entire host. safety. To this end, the host circuit has very strict requirements on the quality and reliability of the electrical connector, and because of the high quality and high reliability of the electrical connector, it is also widely used in military systems such as aerospace, aerospace, and defense.


      Connector testing generally involves the following items:

      Insertion force test, durability test, insulation resistance test, withstand voltage test, vibration test, mechanical impact test, thermal shock test, mixed gas corrosion test, etc.

      The specific test items of the connector are as follows:

      (1) Insertion force test

      Reference standard: EIA-364-13

      Purpose: To verify that the connector's insertion force meets product specifications

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

      (2) Durability test

      Reference standard: EIA-364-09

      Purpose: To evaluate the effect of repeated insertion and removal on the connector, and simulate the plugging and unplugging status of the connector in actual use.

      Principle: The connector is continuously inserted and removed at a specified rate until the specified number of times is reached.

      (3) 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 when subjected to environmental stress such as high temperature and humidity, whether the resistance value meets the requirements of relevant technical conditions.

      Principle: A resistor is applied to the insulating portion of the connector to cause a leakage current to appear on the surface or inside of the insulating portion.

      (4) Withstand voltage test

      Reference standard: EIA-364-20

      Purpose: To verify whether the connector can work safely at rated voltage and whether it can withstand the potential of overpotentials, so as to evaluate whether the connector insulation or insulation gap is suitable: between the connector contacts and the contacts, the contacts and A specified voltage is applied between the outer casings for a predetermined period of time to observe whether the sample has breakdown or discharge.

      (5) 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 contact: by measuring the current through the connector, measuring the voltage drop across the connector to obtain the resistance value

      (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 impact resistance of connectors and their components or to assess their structural strength

      Test waveform: half sine wave, square wave

      (8) Thermal shock test

      Reference standard: EIA-364-32

      Objective: To evaluate the effect of connectors on their functional quality under rapid changes in temperature.

      (9) Temperature and humidity combined cycle test

      Reference standard: EIA-364-31

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

      (10) High temperature test

      Reference standard: EIA-364-17

      Purpose: To evaluate whether the performance of the terminal and insulator changes after the connector is exposed to high temperature for a specified period of time.

      (11) Salt spray test

      Reference standard: EIA-364-26

      Purpose: To evaluate the salt spray 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 on performance.

      (13) Wire Swing Test
