The difference between connectors, terminals, and connectors

  • DATE:2018/4/14 15:42:20

Connectors, terminals, connectors three concepts attribution range, application difference?

Some practitioners in the first entry connector industry can not distinguish between the conceptual differences between the "connector", "terminal" and "connector", the difference in the scope of belonging and the difference in practical application between the three. This article gives a detailed description of the differences between the three.

First, the difference of concept

(1) connector, that is, CONNECTOR. Also called the connector connector. It is a component frequently contacted by electronic engineering technicians. It is also known as plug in, plug and socket in China. Generally, it refers to electrical connector. A device that connects two active devices to transmit current or signal.

The connector is a position connector that connects the electronic circuit. It is composed of 2 parts, namely, the plug-in and the connector. In general, the connector can be completely separated. The same place of the switch and the connector is to change the contact state of the contact to realize the transfer purpose of the circuit, and its essential difference is that the essential difference lies in the connection. Only by inserting two kinds of state, the switch can realize the conversion of the circuit in its ontology, and the connector can not achieve the transformation in the body. The contact of the connector has a fixed corresponding relationship, so the connector can also be called the connector.

Connection terminal, English name Terminal (Zhong Duan). It's an accessory product for electrical connection, which is divided into connectors in industry. The terminal is used to facilitate the connection of the wire. It is actually a piece of metal sealed in the insulating plastic. It has holes at both ends and can be inserted into the wire. The terminals can be divided into WUK terminals, European connection terminals, plug and pull terminal blocks, etc.

Two. Distinguish from the scope of ownership

The connector is the first class, and the terminal is only one of the connectors. Connector is the connection between line and line. Connector is the connection between line and plate and box. In practical applications, it is often classified as a class.

The terminal is part of the connector. Connector is a general term. In fact, the connectors we usually use usually consist of two parts: housing and terminal (terminal). Housing is mostly plastic. It plays a protective role. Terminal is a metal and plays a leading role.

In the electrical and electrical fields:
Connectors, connectors and connectors are the same products. Popular understanding is the kind of tool that does not need tools, and can be quickly connected by hand or plug.
Connection terminals, popular understanding, is the kind of tool, such as a screwdriver, cold pressure tongs to the East and east of the two East and East, generally used for power input, output. English name Terminal (Zhong Duan).

Three. Actual application differentiation

The electrical connector is also called the connector. It is a subdivision area of electronic components. It is mainly used for the connection between circuits and circuits. In industrial production, line connection can be said to be everywhere. Therefore, the range of connectors is certainly very extensive and applied in various industries.

Connector is divided into many categories, such as rectangular connector, circular connector, ladder type connector and so on. The terminal line terminal is one kind of connector, generally it belongs to the rectangular connector. The use of terminal row is also relatively simple. It is commonly used in the field of electronics and electrical field, and is used for internal wiring of PCB circuit boards, PCB and distribution cabinets.

The use of terminals is more and more, and there are more and more kinds. In addition to the most widely used PCB terminal, there are hardware terminals, nut terminals, spring terminals, etc. in the power industry, there are special terminals and terminal boxes, all of which are terminal terminals, single layer, double layer, current, voltage, ordinary, broken, etc.

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