Distinction between connectors, terminals and connectors

Some practitioners who are new to the connector industry cannot distinguish the differences in concepts, ownership scopes, practical applications, etc. of "connectors", "terminal blocks" and "connectors". This article mainly introduces the following three differences.

1. Conceptual differences 1. Connectors, also known as connectors connectors. It is a component that electronic engineers and technicians often come into contact with. In China, it is also called plug-in, plug and socket. Generally refers to electrical connectors. A device that connects two active devices, transmits electrical currents, or signals. 2. The connector is a position connector that connects electronic circuits. It consists of two parts: a plug-in and a connector, which can usually be completely separated. The switch and connector are in the process of changing the contact state through contact. To achieve the purpose of connecting circuit conversion, the essential difference is that the plug can only be inserted into two states, and the switch can perform circuit conversion on the main body, so the connector can also be called a connector. 3. Wiring terminals are accessory products that realize electrical connections, and are industrially divided into connectors. Terminal blocks are applied to facilitate wiring. That is, there are holes at both ends to insert the metal sheet surrounded by the insulating plastic of the wire. The terminal block can be divided into WUK terminal block, European terminal block series, plug connection terminal series, etc. 2. Practical application distinction Electrical connectors are sometimes called connectors, sometimes called connectors, which are subdivided areas of electronic parts and are mainly used for connections between circuits. In industrial production, line connections can be said to be ubiquitous, so connectors are of course widely used and suitable for all walks of life. Connectors are divided into rectangular connectors, circular connectors, ladder connectors and other categories, and terminal blocks usually belong to rectangular connectors. The application range of terminal blocks is also relatively simple. They are generally used in electronic and electrical fields and are used for internal and external connections of PCB circuit boards, printed boards and distribution boxes. Terminal blocks are being used more and more, and there are more and more varieties. At present, the most widely used in addition to PCB board terminals, there are also hardware terminals, nut terminals, spring terminals, etc. The power industry has special terminal blocks, terminal boxes, all with terminal blocks, single-layer, double-layer, current, voltage, conventional, detachable, etc. Generally, "connector", "terminal block" and "connector" are different representations belonging to the same concept and are named according to different practical applications.
