I. First, let's distinguish the concepts of "connector", "terminal", and "plug".
① Connector, i.e., CONNECTOR. Also called a plug connector. It is a component frequently encountered by electronic engineering personnel. Also known as a plug, jack, and socket. It generally refers to an electrical connector, i.e., a device that connects two active devices to transmit current or signals.
② A plug is a positioning connector that connects electronic circuits. It consists of two parts: a plug and a receptacle. They are generally completely separable. The similarity between a switch and a plug lies in achieving the purpose of switching the connected circuit through changes in the contact state of their contact pairs. The essential difference is that the plug only has two states: insertion and removal, while the switch can switch the circuit on its body, but the plug cannot. The contact pairs of the plug have a fixed correspondence, so the plug can also be called a connector.
③ Terminal, English name Terminal. It is an accessory product used to achieve electrical connection. In industry, it is classified under the category of connectors. Terminals are used for convenient wire connection. It is actually a piece of metal enclosed in insulating plastic, with holes at both ends for inserting wires. Terminals can be divided into WUK terminals, European terminals, and pluggable terminals, etc.
II. Distinguishing "connector", "terminal", and "plug" from the scope of their affiliation
① "Connector = Plug" is the first major category. Terminals are just one type within the larger category of "connectors".
What's the difference between a plug and a connector?
A connector connects wire to wire; a plug connects wire to board and box. In real life, people often vaguely refer to the same thing.
② Terminals are part of a connector. Connector is a general term. In fact, the connectors we usually see typically consist of two main parts: housing and terminals. The housing is mostly plastic and provides protection, while the terminal is metal and is used for conduction.
