Automotive connectors some basic testing items

Automotive connector reliability testing generally touches on the following items: insertion and extraction force testing, durability testing, insulation resistance testing, voltage testing, oscillation testing, mechanical shock testing, thermal shock testing, mixed gas corrosion testing. So these automotive connector test items intended to detect the principle, intent and reference specifications and what are they? Briefly organized part of the automotive connector test content, the first is as follows:

Insertion and extraction force test reference specification: EIA-364-13 intention: to verify that the connector insertion and extraction force is in line with the product specification requirements principle: the automotive connector according to the rules of the rate of complete insertion and removal, record the corresponding force value durability test reference specification: EIA-364-09 intention: to detect the impact of repeated insertion and removal of the connector to mimic the actual use of connector insertion and removal of the situation principle: according to the rules of the rate of continuous insertion and removal of automotive connectors until the number of times the rules. Principle: according to the rules of the rate of continuous plugging and unplugging of automotive connectors until it reaches the rules of the number of times. Insulation resistance test reference standard: EIA-364-21 intention: to verify that the insulation function of the automotive connector is in line with the requirements of the circuit design or full of high temperature, humidity and other environmental stresses, its resistance value is in line with the rules of the relevant technical conditions. Principle: Apply voltage to the insulating part of the connector, and then make the surface of the insulating part or the internal leakage current and the resistance value. Withstand voltage test reference standard: EIA-364-20 intention: to verify the automotive connector in the extra voltage can be safe operation, can withstand over-potential ability, and then determine the connector insulation materials or insulation space is suitable for the principle: in the connector between the contact parts and contacts, contacts and shells between the application of the rules of the voltage and adhere to the rules of the moment, to observe the sample whether there is a breakdown or discharge phenomenon. Contact resistance test reference specification: EIA-364-06 / EIA-364-23 intention: to verify the current flow through the contact surface of the contact occurs when the resistance value principle: through the connector through the rules of the current, measuring the connector voltage drop on both sides and then derive the resistance value of the oscillation test reference specification: EIA-364-28 intention: to verify that the oscillation of the electrical automotive connector and its components function of the impact Oscillation type: random oscillation, sinusoidal oscillation mechanical shock test reference standard: EIA-364-27 intention: to verify the automotive connector and its components shock resistance or determine whether the structure is strong test waveform: half-sine wave, square wave thermal shock test reference standard: EIA-364-32 intention: to detect the automotive connector in the rapid change of temperature difference, the impact on the quality of its function. Temperature and humidity combined cycle test reference specification: EIA-364-31 intention: to detect the automotive connectors in the high temperature and high humidity environment through the storage of the connector function of the impact of high-temperature test reference specification: EIA-364-17 intention: to detect automotive connectors exposed to high temperatures in the environment in the rule of the time after the terminals and the insulator function of the change occurs in salt spray test reference specification: EIA-364-36 intention: to test the automotive connectors, terminals, insulators, and the quality of the connector function, the quality of the connector function. 26 Intent: To test the salt spray corrosion resistance of automotive connectors, terminals and plating, mixed gas corrosion test reference specification: EIA-364-65 Intent: To test the corrosion resistance of automotive connectors exposed to different concentrations of mixed gases and the effect on their function Wire shaking test reference specification: EIA-364-41
