In the process of providing electrical solutions to customers, it is often encountered that customers do not know the differences in the use of connectors, terminals, and connectors when purchasing.

Today, based on my own professional experience and industry knowledge, I would like to share and explore the similarities and differences among the three.

The difference between defining "connector", "terminal block" and "plug-in" in the industry

1. Connector CONNECTOR. Also known as connectors, plugs, and sockets domestically. It is a component that electronic engineering technicians often come into contact with. Generally refers to electrical connectors. A device that connects two active components and transmits current or signals.

2. Terminal for wiring. It is a type of accessory product used to achieve electrical connections. It is applied for the convenience of wire connection. It is actually a metal sheet sealed in insulating plastic, with holes at both ends for inserting wires.

Wiring terminals can be divided into rail mounted terminals, plug-in terminals, European style terminals, etc.

3. A connector is a positioning joint that connects electronic circuits, consisting of two parts: a plug and a connector. In general, they can be completely separated. Therefore, a connector can also be called a connector.

From the perspective of belonging scope, connectors and connectors are a general term and the first major category, with terminals being a part of it.

Distinguish the application of "connectors", "terminal blocks", and "connectors"

A connector can be understood as a component that can be quickly connected with a male or female head by hand without the need for tools. It is mainly used for connecting circuits.

In industrial production, circuit connections can be said to be ubiquitous, so the use of connectors is certainly very extensive and applied in various industries.

There are many categories of connectors, such as rectangular connectors, circular connectors, stepped connectors, and so on. Wiring terminals generally belong to rectangular connectors and require tools such as screwdrivers to connect two components together. There are categories such as spring terminals, screw terminals, PCB board terminals, hardware terminals, etc.

Generally used in the field of electronics and electrical engineering, it is used for internal and external wiring of distribution cabinets, PCB circuit boards, and printed boards, such as Supu spring terminal blocks and UK screw terminal blocks.

The difference between connectors and connectors is that the latter is the connection between wires, while the former is the connection between wires, boards, and boxes.

In general, "connector", "terminal block", and "plug-in" are different forms of application that belong to the same concept and are commonly referred to according to different practical applications.
