Concept and application of connector, connector and terminal
2018-09-10

Today, based on my own experience and industry knowledge, I will discuss the commonalities and differences of the three.


1. The industry defines the difference between "connector", "terminal" and "connector"


1. CONNECTOR. Also known as connectors, plugs and sockets in China. It is a component that electronic engineering and technical personnel often contact. Generally refers to electrical connectors. That is, a device that connects two active devices to transmit current or signal.


2. Terminal. It is an accessory product used to realize electrical connection. It is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic with holes at both ends for inserting wires.

Terminals can be divided into rail-mounted terminal blocks, plug-in terminal blocks, European-style terminal blocks, etc.


3. The connector is a positioning connector for connecting electronic circuits. It is composed of two parts, namely the connector and the connector. Under normal conditions, they can be completely separated. Therefore, the connector can also be called a connector.

From the perspective of the scope of attribution, connectors and connectors are a general term, the first category, and terminals are part of it.


2. Distinguish the application of "connector", "terminal" and "connector"


Connectors can be understood as components that can be quickly connected without tools, male and female plugs by hand or screwed, and are mainly used for the connection between circuits.


In industrial production, line connections can be said to be ubiquitous, so the scope of use of connectors is of course very wide, used in various industries.


Connectors are divided into many categories, such as rectangular connectors, circular connectors, stepped connectors and so on. Terminals are generally rectangular connectors and require tools, such as a screwdriver, to connect two components together. There are spring terminals, screw terminals, PCB board terminals, hardware terminals, and so on.


Generally used in the field of electrical and electronics, used for internal and external wiring of power distribution cabinets, PCB circuit boards and printed boards, such as Supu spring terminals and UK screw terminals.


The difference between the connector and the connector is that the latter is the connection between the line and the line, and the former is the connection between the line and the board and the box.


In general, "connector", "terminal", and "connector" are different application manifestations that belong to the same concept, and are commonly called according to different practical applications.
