Connectors are also called connectors. Also known as connectors and sockets in China, they generally refer to electrical connectors. A device that connects two active components and transmits current or signals.   

Among all the electronic components that make up the entire system, connectors may seem structurally simple and often go unnoticed, but their failure probability is the highest.

The three basic performance characteristics of connectors

1. In terms of connection function, insertion and extraction force is an important mechanical performance; Another important mechanical performance is the mechanical lifespan of the connector.

The main electrical performance of electrical connectors includes contact resistance, insulation resistance, and electrical strength.

3. Common environmental performance includes resistance to temperature, humidity, salt spray, vibration, and impact.

There are three common forms of fatal faults in terminal blocks:

1. Poor contact

2. Poor insulation

3. Poor fixation

The quality of the gold plating layer on connectors is one of the important parameters for evaluating the quality of connectors. The base material of the connector is copper alloy, and the surface coating is gold and its alloys. Nickel plating is applied between the base copper and the surface gold coating.
