Some practitioners in the connector industry can't distinguish the conceptual differences between the "connectors", "terminals" and "connectors", the difference in attribution range, and the actual application differences. This article gives you a detailed introduction to the differences between the three:

First, the concept difference

1 connector, CONNECTOR. Also called the connector connector. It is a component that electronic engineering technicians often come into contact with. Domestically referred to as connectors, plugs and sockets. Generally refers to electrical connectors. That is, a device that connects two active devices to transmit current or signals.

2 Connector is a kind of positioning connector for connecting electronic circuits. It is composed of two parts, namely, the plug-in, and the connector. In general, it can be completely separated. The same place of the switch and the connector lies in the contact state through the contact pair. The change, the purpose of the conversion of the connected circuit, and the essential difference is that the plug is only inserted and removed, the switch can realize the conversion of the circuit on its body, and the connector can not achieve the conversion on the body. There is a fixed correspondence between the contact pairs of the connectors. Therefore, the connectors can also be called connectors.

3 terminal block, English name Terminal (terminal). It is an accessory product for electrical connection, which is industrially divided into connectors. The terminal block is used to facilitate the connection of the wire. It is actually a piece of metal that is sealed inside the insulating plastic. There are holes at both ends to insert the wire. The terminal blocks can be divided into WUK terminal blocks, European terminal blocks series, and plug-in terminal blocks.

Second, distinguish from the scope of attribution

1 "Connector = Connector" is the first category, and the terminal block is just one of the "connectors" category. The connector is a wire-to-wire connection; the connector is the wire-to-board connection. In practice, it is often classified into one category.

The 2 terminal is part of the connector. Connectors are a general term. In fact, the connectors we usually use usually include two parts: housing and terminal. Housing is mostly plastic, plays a protective role, terminal is a metal, which acts as a conduction.

3 In the field of electrical and electrical:

Connectors, connectors, connectors are the same product. It is a common understanding that the male and female heads can be quickly connected by hand or by twisting without tools.

Terminals, commonly understood, are the kind of tools that can be used to connect two Dongdong tools, such as screwdrivers and cold-pressing pliers, which are generally used for power input and output. English name Terminal (terminal).

Third, the actual application of differentiation

The electrical connector is referred to as a connector, also called a connector, and is a subdivision of electronic components, mainly used for the connection between circuits and circuits. In industrial production, the line connection can be said to be ubiquitous, so the range of use of the connector is of course very extensive, and it is applied in various industries.

The connector is divided into many categories, such as a rectangular connector, a circular connector, a stepped connector, etc., and the terminal block is a type of connector, generally belonging to a rectangular connector. The terminal block is also used in a single range, and is generally used in the field of electronic and electrical, and is used for connecting internal and external wiring of PCB circuit boards, printed boards and power distribution cabinets.

The use of terminal blocks is increasing and the variety is increasing. At present, in addition to PCB board terminals, there are also hardware terminals, nut terminals, spring terminals, etc. In the power industry, there are special terminal blocks, terminal boxes, all of which are terminal blocks, single-layer, double-layer , current, voltage, normal, breakable, etc.

In general, "connectors", "terminals", and "connectors" are different application manifestations that belong to the same concept and are named according to different practical applications.
