What’s scope and application difference between connector and terminal block?

Some practitioners in the connector industry can not distinguish the concept difference between "connector "," terminal" and "connector ", the difference of ownership range, and the difference of practical application. This article gives you a detailed introduction of the following three differences:

I. Conceptual distinctions

1 connector, it is a component that electronic engineering technicians often contact. Domestic also known as connectors, plugs and sockets. Generally refers to electrical connectors. A device that connects two active devices to transmit current or signal.

A connector is a positioning connector connected to an electronic circuit, which is composed of two parts, namely, a plug-in and a connector, which can be completely separated in general. The same part of the switch and the connector is to realize the purpose of switching the connected circuit by changing the contact state of the contact pair.

3 terminal, it is a kind of accessory product used to realize electrical connection, which is divided into connector category in industry. The terminal is used to facilitate the connection of conductors. It is actually a piece of metal sealed in insulating plastic with holes at both ends and can be inserted into the wire. Terminal can be divided into WUK terminal, European terminal series, plug-in terminal series.

II. Distinction from scope of attribution

1" Connector = Connector "is the first category, terminals are only one of the" connector "categories. The connector is the connection between the line and the line; the connector is the connection between the line and the board and the box. In practical application, it is often classified as a class.

Terminal 2 is part of the connector. Connectors are a general term, in fact, we often see connectors, usually including shell (housing) and terminal (terminal) two parts. housing is plastic in the majority, play a protective role, terminal is metal, play a conductive role.

3. In the electrical and electrical fields:

Connectors, connectors, connectors are the same product. Popular understanding, is the kind of tools, male head, female head with a hand or a twist can quickly connect things.

Wiring terminals, popular understanding, is the kind of tools, such as screwdrivers, cold-pressing forceps to connect two things together, generally used for power input, output. English name Terminal (terminal).

III. Distinction between practical applications

Electrical connectors, also known as connectors, are a subdivision of electronic components, mainly used in the connection between circuits. In industrial production, line connections can be said to be ubiquitous, so connectors are of course widely used in various industries.

Connectors are divided into many categories, such as rectangular connectors, circular connectors, ladder connectors and so on, wiring terminal row is one of the connectors, generally belong to rectangular connectors. Terminal row is also relatively single, generally used in the field of electronics and electrical, used to PCB circuit boards, printed boards and distribution cabinets inside and outside the line.

The use range of terminal is more and more, and the variety is more and more. At present, the most widely used in addition to PCB board terminals, there are hardware terminals, nut terminals, spring terminals and so on, in the power industry has a special terminal row, terminal box, above are all wiring terminals, single-layer, double-layer, current, voltage, ordinary, breakable and so on.

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