Connector inspection certification

Basic introduction

Definition of connector: CONNECTOR. It is also called as connector, plug and socket in China. Generally refers to electrical connectors. That is, a device that connects two active devices and transmits current or signals.

Basic performance

The basic performance of connectors can be divided into three categories:
1. Mechanical properties
2.Electrical performance
3. Environmental performance

Common tests and reference standards

Appearance size test
Reference standard: EIA-364-18
1. Check whether the appearance of the sample has an effect on product performance or abnormal product test results
2. Check whether the product specifications meet the product requirements and relevant standards or association specifications
Insertion force test
Reference standard: EIA-364-13
Purpose: To verify that the mating force of the connector meets the product specifications
Principle: Fully insert or pull out the connector at the specified rate, and record the corresponding force value
Endurance test
Reference standard: EIA-364-09
Purpose: To evaluate the impact of repeated plugging on the connector and simulate the plugging and unplugging of the connector in actual use
Principle: The connector is continuously plugged and unplugged at the specified rate until the specified number of times.
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 whether the resistance value meets the requirements of relevant technical conditions when subjected to environmental stresses such as high temperature and humidity.
Principle: Apply a voltage to the insulation part of the connector, so that the surface or the inside of the insulation part generates a leakage current and the resistance value appears.
Withstand voltage test
Reference standard: EIA-364-20
Purpose: To verify whether the connector can work safely under rated voltage, and whether it can withstand overpotential, so as to evaluate whether the connector insulation material or insulation gap is suitable Apply a specified voltage between the shells and hold it for a specified time, and observe whether the sample has breakdown or discharge.
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. Principle: By applying a specified current to the connector, measuring the voltage drop across the connector to obtain the resistance value
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
Mechanical shock test
Reference standard: EIA-364-27
Purpose: To verify the impact resistance of connectors and their components or to evaluate whether their structures are firm
Test waveform: half sine wave, square wave
Cold and hot shock test
Reference standard: EIA-364-32
Purpose: Assess the impact of connectors on their functional quality under rapid large temperature changes
Temperature and humidity combined cycle test
Reference standard: EIA-364-31
Purpose: To evaluate the effect of connectors on connector performance after storage in high temperature and high humidity environments
High temperature test
Reference standard: EIA-364-17
Purpose: To evaluate whether the performance of the terminal and the insulator changes after the connector is exposed to a high temperature environment for a specified time
Salt spray test
Reference standard: EIA-364-26
Purpose: To evaluate the resistance of connectors, terminals, and coatings to salt spray corrosion
Mixed gas corrosion test
Reference standard: EIA-364-65
Purpose: To evaluate the corrosion resistance of connectors exposed to different concentrations of mixed gases and their effects on their performance
Wire swing test
Reference standard: EIA-364-41
Purpose: Assess the connector's ability to withstand repeated back and forth stress and evaluate electrical continuity in the process
Temperature rise test
Reference standard: EIA-364-70
Purpose: To evaluate whether the temperature rise of the terminal exceeds the specified value when the terminal is subjected to the rated current
