Due to the diversification of the structure of the electronic cable, new structures and application areas are emerging. And it is difficult to solve the classification and naming problems with a fixed pattern. However, some basic categories are still valid.

The level of interconnection is divided into five levels based on the capabilities of the internal and external connections.

1. The chip encapsulates the internal connection

2. IC package pin and PCB connection. Typical connector IC socket.

3. A printed circuit is connected to a wire or printed circuit board. Printed circuit connector typical connector.

4. Baseplate and connection. Cabinet connector typical connector.

5. Device to device connection. Typical products are round connectors.

Cable specifications according to the International Electrotechnical Commission (IEC) For example, electronic equipment is a connector, electromechanical components Category: SPECIFICATIONS Level: Subcategory: Connector Circular Connector Type: YB Circular Connector Species: yb3470 Specifications

In the management of electronic connector in China, connectors, switches, keyboards, etc. are collectively referred to as electrical connector components, while electrical connector components and relays are collectively referred to as electromechanical components.
