1. First, distinguish the concepts of "connector", "terminal" and "connector"

①Connector, namely CONNECTOR. Also called plug-in connector. It is a component that electronic engineering and technical personnel often contact. Also called connectors, plugs and sockets. Generally refers to electrical connectors. That is, a device that connects two active devices to transmit current or signal.

②The connector is a positioning connector for connecting electronic circuits. It is composed of two parts, namely the plug and the connector. Under normal conditions, they can be completely separated. The switch and the connector are similar in the contact state of the contact pair. The change to achieve the conversion purpose of the connected circuit, and the essential difference is that the connector has only two states of insertion and removal. The switch can realize the conversion of the circuit on its body, but the connector cannot realize the conversion on the body. , The contact pair of the connector has a fixed corresponding relationship, therefore, the connector can also be called a connector.

③Connecting terminal, English name Terminal (terminal). It is an accessory product used to realize electrical connection, which is divided into the category of connectors in industry. The terminal block is used to facilitate the connection of the wire. It is actually a piece of metal enclosed in insulating plastic, with holes at both ends, which can be inserted into the wire. Terminals can be divided into WUK terminal, European terminal series, plug-in terminal series, etc.

2. Distinguish "connectors", "terminals" and "connectors" from the scope of attribution

①"Connector=connector" is the first category, and the terminal block is only one of the "connector" categories

What is the difference between a connector and a connector?

The connector is the connection between the line and the line; the connector is the connection between the line and the board and the box. In real life people often refer to the same thing vaguely.

②The terminal is part of the connector. Connector is a general term. In fact, the connectors we commonly see usually include two parts: housing and terminal. Housing is mostly plastic, which plays a protective role, while the terminal is metal, which is universal.
