Distinguishing connectors, plugins, and terminals

1、Distinguish the concepts of "connector", "terminal block", and "connector"

①Connector, also known plug-in connectors. It is a component that electronic engineering technicians often come into contact with. Also known as connectors, plugs, and sockets. Generally refers to electrical connectors. A device that connects two active devices to transmit current or signals.

②A connector is a positioning connector that connects electronic circuits, consisting of two parts: a connector and a connector. Generally, they can be completely separated. The similarity between a switch and a connector is that they change the contact state of their contact pairs to achieve the purpose of converting the circuit they are connected to. The essential difference is that the connector only has two states: insertion and removal, and the switch can convert the circuit on its body, However, connectors cannot achieve conversion on the ontology, and there is a fixed correspondence between the contact pairs of connectors. Therefore, connectors can also be called connectors.

③Terminal block is a type of accessory product used to achieve electrical connections, which is classified as a connector in industry. Terminal blocks are used for the convenience of connecting wires. They are actually a piece of metal enclosed in insulating plastic, with holes at both ends for inserting wires. Wiring terminals can be divided into WUK wiring terminals, European wiring terminal series, plug-in wiring terminal series, etc.

2、Distinguish between "connectors", "wiring terminals", and "connectors" based on their scope of ownership

①"Connector=connector" is the first major category, and wiring terminals are just one type of "connector" category

What is the difference between connectors and connectors?

A connector is a connection between wires; A connector is a connection between wires, boards, and boxes. In real life, people often refer vaguely to the same thing.

The terminal is part of the connector. A connector is a general term, which usually includes two parts: a rubber shell and a terminal. Housing is mostly made of plastic for protective purposes, while terminal is made of metal for conductivity purposes.
