The basic performance of connectors is divided into mechanical performance, electrical performance, and environmental performance.
1. Mechanical performance
In terms of connection function, insertion and extraction force is an important mechanical performance. The insertion and extraction forces are divided into insertion force and extraction force (also known as separation force), and their requirements are different.
2. Electrical performance
The main electrical properties of connectors include contact resistance, insulation resistance, and electrical strength High quality electrical connectors with contact resistance should have low and stable contact resistance. The contact resistance of connectors varies from a few milliohms to tens of milliohms The insulation resistance is an indicator that measures the insulation performance between the contact parts of an electrical connector and between the contact parts and the shell, with an order of magnitude ranging from hundreds of megaohms to thousands of megaohms Electrical strength, also known as voltage resistance or dielectric withstand voltage, is the ability of a connector to withstand the rated test voltage between its contacts or between the contacts and the housing Other electrical performance.
3. Environmental performance
Common environmental performance includes temperature resistance, humidity resistance, salt spray resistance, vibration and impact resistance, etc; The surface treatment layer of its metal structural components and contact parts may cause electrochemical corrosion, affecting the physical and electrical performance of the connector.
