First, the basic structure of the electric connectors:

In general, the connector consists of contacts, insulators, housings, seals, connecting rings (or guide keys), and cable accessories. as the picture shows:

However, this basic structural form is not static. For example, some printed board connectors have no housing and cable clamps due to space and environmental constraints.

Second, the basic performance:

1, electrical performance
The electrical performance is to check whether the electrical parameters meet the requirements after the electrical connector is normally connected. When selecting the electrical connector, the user pays more attention to the rated current, withstand voltage, contact resistance, insulation resistance, and electrical continuity of the casing.

2, mechanical properties
Mechanical properties are considered to be the degree of structural and electrical properties affected by mechanical stress. Users should pay more attention to vibration, shock, acceleration, mechanical life, collision and other indicators when choosing.

3, environmental performance
The environmental performance is to investigate the degree of structural and electrical performance affected by the environment. Users should pay more attention to temperature shock, humidity, high temperature, low temperature, water pressure seal, salt spray and other indicators when choosing.
