basic introduction

Definition of connector: CONNECTOR. Domestically also known as connectors, plugs and sockets. Generally refers to electrical connectors. That is, a device that connects two active devices, transmitting 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

purpose:

1. Check whether the appearance of the sample will affect the product performance or affect the product test results.

2. Check whether the product specifications and sizes meet the product requirements and related standards or association specifications

Plug force test

Reference standard: EIA-364-13

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

Principle: fully insert or pull out the connector at the specified rate, and record the corresponding force value

Durability test

Reference standard: EIA-364-09

Purpose: To evaluate the impact of repeated insertion and removal on the connector, and to simulate the actual insertion and removal of the connector

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

Insulation resistance test

Reference standard: EIA-364-21

Purpose: To verify whether the insulation performance of the connector meets the requirements of the circuit design or when it is subjected to environmental stresses such as high temperature and humidity, and whether its resistance value meets the requirements of the relevant technical conditions.

Principle: The voltage is applied to the insulated part of the connector, so that the resistance value is caused by the leakage current generated on the surface or inside of the insulated part.

Withstand voltage test

Reference standard: EIA-364-20

Purpose: To verify whether the connector can work safely at rated voltage and to withstand the ability of overpotential, so as to assess whether the connector insulation material or insulation gap is appropriate. Principle: Between the connector contact and the contact, the contact Apply the specified voltage between the shells and keep it for a specified time, and observe whether the sample has a breakdown or discharge phenomenon.

Contact resistance test

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

Purpose: To verify the principle of the resistance value generated when the current flows through the contact surface of the contact: By applying a prescribed 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 impact 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 the connector and its components or to assess whether the structure is strong

Test waveform: half sine wave, square wave

Thermal shock test

Reference standard: EIA-364-32

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

Temperature and humidity combined cycle test

Reference standard: EIA-364-31

Objective: To evaluate the impact of the connector on the performance of the connector after being stored in a high temperature and high humidity environment

High temperature test

Reference standard: EIA-364-17

Purpose: To evaluate whether the performance of the terminal and insulator has changed after the connector is exposed to 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 corrosion by salt spray

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 the impact on their performance

Wire swing test

Reference standard: EIA-364-41

Purpose: To evaluate the ability of the connector to withstand repeated response forces and to evaluate the 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 passing the rated current
