1. Difference in concept
(1) CONNECTOR. Also known as a plug-in connector, plug, or socket, it is a type of component that is often touched by electronics and technical personnel and generally refers to an electrical connector. That is, a device that connects two active devices to transmit current or a signal. Connectors are mainly used for connections between circuits. It is the basic element of the core required for the electrical connection of circuit systems. The main application areas for connectors are smart home and automotive. , communications, computers and peripherals, industrial, military and aerospace. With development, the scope of application will become wider and wider. They are basically used in various industries. Connectors come in many categories, such as circular connectors, rectangular connectors, and stepped connections. Terminal blocks generally belong to rectangular connectors, and the scope of application of terminal blocks is relatively single. It is commonly used in the electronic and electrical fields, for internal and external wiring of PCB circuit boards, printed circuit boards, and power distribution cabinets.
(2) Connectors are positioning connectors for connecting electronic circuits. It consists of two parts: connector and connector. Under normal conditions they can be completely separated. Therefore, connectors are sometimes called connectors. switches and connectors. The analogy of a plug-in unit is that it achieves the conversion purpose of the connected circuit by changing the contact state of the contact pair. The essential difference is that the plug-in only has two states, inserted and removed, and the switch can realize the transformation of the circuit of the body. However, the connector cannot achieve conversion on the body, and the contact pairs of the connector are in fixed correspondence. Therefore, connectors are also called connectors.
③ Terminal, English name Terminal (Terminal). It is an accessory product used to make an electrical connection and falls under the connector category in the industry. Terminals are used to facilitate the connection of wires. They are actually strips of metal surrounded by insulating plastic, with holes at each end to allow wires to be inserted. Terminals can be divided into WUK terminals, European terminal series, plug-in terminal series and so on. terminal. Accessories for realizing electrical connection. Used to facilitate the connection of wires. It's actually a piece of metal surrounded by insulating plastic. There are holes for inserting wires on both ends. The terminal is currently in use. The most widely used are PCB board terminals, in addition to hardware terminals, nut terminals, spring terminals, rail mount terminal blocks, plug-in terminal blocks, European style terminal blocks, etc.
Electrical connectors, also known as connectors, are a subdivision of electronic components and are primarily used to connect circuits. Line connections are ubiquitous in industrial production, so the scope of use of connectors is of course very wide and they are used in a wide variety of industries.
Connectors fall into many categories, such as rectangular connectors, circular connectors, and stepped connectors. A terminal block is a type of connector, usually a rectangular connector. The scope of use of terminal blocks is relatively simple, commonly used in the field of electronics and electricity, used for internal and external wiring of PCB circuit boards, printed circuit boards, power distribution cabinets.
The range of use of terminal blocks has expanded, and the number of types has also increased. In addition to PCB terminals, the most widely used terminals include hardware terminals, nut terminals, spring terminals, etc. The power industry has special terminal blocks and terminal boxes, all terminal blocks, single layer and duplex. layer, current, voltage, common, fragile, etc.
In general, "connector", "terminal" and "connector" are manifestations of different applications belonging to the same concept and are named according to different actual applications. I'm here.
