First, distinguish the concepts of "connector", "wiring terminal" and "connector"

① CONNECTOR, namely CONNECTOR. Also called connector connector. Electronic engineers often contact with a component. Also called connectors, plugs and sockets. This usually refers to electrical connectors. A device that connects two active devices and transmits current or signals.

(2) the connector is a kind of connection circuit, the positioning of the joint is made up of two parts, namely the plug-in, and fittings, general condition can be completely separated, switches and connectors in the same through its contact with the change of contact state, the transition of the connect circuit of purpose, and is the essential difference between plug only insert pulling two states, A switch can convert a circuit on its own body, but a connector cannot. The contact pair of a connector has a fixed correspondence. Therefore, a connector can also be called a connector.
③ Wiring Terminal, English name Terminal. Is used to achieve electrical connection of a kind of accessory products, industry divided into the category of connector. A terminal is a piece of metal enclosed in insulating plastic with holes at both ends for insertion of wires. Terminal blocks can be divided into WUK terminal block, European terminal block series, plug plug terminal block series and so on.
Ii. Distinguish "connectors", "wiring terminals" and "connectors" from the owning range
① "connector = connector" is the first category, and terminal is only one of the "connector" categories
What is the difference between a connector and a connector?
A connector is a wire to wire connection; A connector is a connection between wire and board and box. In real life people often refer vaguely to the same thing.
② The terminal is part of the connector. Connector is a general term, in fact, we commonly see connectors, usually including housing and terminal two parts. Housing is mostly plastic, which plays a protective role, while terminal is metal, which plays a guiding role.
