A power connector (also commonly known as a circuit connector or electrical connector) is a type of connector used to transmit electronic signals or electrical energy. For example, there are many connectors on computer motherboards, such as your USB interface and the power interface on the chassis, which are connectors. However, they are different connectors when subdivided. When it comes to the internal connection, the connection between boards, such as the card slot of a graphics card, is also a connector. That form should be called a golden finger. Connectors are widely used in various fields, such as automobiles, industrial computers, personal computers, communication, and many other areas.

A power connector is a device that transmits electronic signals (analog or digital), providing a separate interface for connecting two secondary electronic systems. It is a component used to complete electrical connections between circuits or electronic machines. For example, power plugs/sockets, IC sockets, telephone line plugs, etc. are all included. Widely used in the electronics industry.

1. Temperature: Accelerated corrosion, surface formation, oxidation, contact pressure loss;

2. Adverse environment: pore corrosion, edge deformation, surface particle corrosion;

3. Vibration: making noise, data bit loss, wear and tear;

4. Humidity: accelerates corrosion, forms surface, oxidizes, degrades plastic film;

5. Usage time: Wear and tear.
