What is the connector inspection standard? What aspects of the connector need to focus on inspection?

Connectors are essential components in modern electronic devices. They can connect different circuit boards, cables and devices to achieve functions such as signal transmission and power supply. In the production and maintenance of electronic equipment, the quality and reliability of connectors have a very important impact on the performance and life of the whole system. Therefore, during the production, installation and maintenance of the connector, a series of inspections and tests are needed to ensure the quality and reliability of the connector. Connector inspection standards can be developed and implemented according to different applications and industry requirements. Generally speaking, the inspection standards of connectors shall meet the following requirements: 1. Appearance inspection: This is the most basic inspection, which is mainly used to check whether the appearance of connectors meets the requirements of manufacturing standards and specifications. Appearance inspection usually includes the inspection of shell, pin, socket, interface and other components, as well as the inspection of connector size, color, surface quality and other aspects. 2. Mechanical performance test: This is one of the important performances of the connector, which is used to test the mechanical strength, durability, contact pressure and other indicators of the connector. Mechanical performance inspection usually includes insertion and extraction force test, locking force test, friction test, etc., to ensure that the connector will not appear loose, wear and other problems in long-term use. 3. Electrical performance test: This is one of the most important performances of the connector, which is used to test the electrical characteristics and signal transmission performance of the connector. Electrical performance inspection usually includes contact resistance test, insulation resistance test, signal transmission test, etc., to ensure that the connector has good performance and stability in signal transmission and power supply. 4. Environmental adaptability test: This is a test for the use requirements of connectors in different environments. Environmental adaptability test usually includes temperature resistance test, moisture resistance test, corrosion resistance test, etc. To ensure that the connector can maintain stable performance and reliability under different environmental conditions. In addition to the above inspections, different inspections and tests are required for specific connector types and application scenarios. For example, for connectors with high-speed signal transmission, signal integrity test and crosstalk test are also required; for waterproof connectors, water tightness test and water resistance depth test are also required. At the same time, the packaging, marking, packaging and transportation of connectors also need to be inspected.
