How to test the connector? What are the main equipment for testing?

Connector is an important component used to connect electronic components, circuit boards, cables and other electrical equipment. The stability and reliability of its performance are very important for the normal operation of the whole system. In order to ensure that the quality and performance of the connector meet the design requirements, it is necessary to carry out appropriate testing. Next, the detection method and related equipment of the connector will be described. 1. Connector inspection method 1. Appearance inspection: mainly check the surface and shape of the connector, including whether the size, shape, color and material of the connector meet the requirements, and whether there are obvious damage, deformation, scratches, etc. 2. Electrical performance test: The electrical performance of the connector is one of its most important performances, including the test of contact resistance, insulation resistance, dielectric withstand voltage, current capacity and other indicators. Among them, contact resistance is an important index to detect the quality of connectors, which is generally required to be less than 5 milliohms. 3. Mechanical performance test: including the test of insertion and extraction force, insertion and extraction times, wear resistance, etc. The stability and reliability of mechanical properties are essential for the life and reliability of the connector. 4. Environmental test: mainly including salt spray test, high temperature test, low temperature test, damp heat test, etc., to test the performance of the connector in different environments to ensure its stability and reliability. 5. Functional test: For some connectors with special functions, such as sensor connectors, optical fiber connectors, etc., specific functional tests are required to ensure their normal functions. 2. Connector testing equipment 1. Contact resistance tester: It is used to test the contact resistance of connectors and is one of the main equipment for connector testing. 2. Universal electrical tester: It can test the electrical parameters of connectors, such as insulation resistance, dielectric withstand voltage, current capacity, etc. 3. Load plug tester: used to test the mechanical properties of the connector, such as plug force, plug times, etc. 4. Salt spray test chamber, high and low temperature test chamber, damp heat test chamber and other environmental test equipment: used to test the performance of connectors in different environments. 5. Optical microscope, magnifying glass and other observation equipment: used to check the appearance and details of the connector. 6. Function tester: used to test the functional performance of connectors with special functions.
