Concept difference
①Connector, namely CONNECTOR. Also called plug-in connectors, plugs and sockets, are a kind of components that electronic engineering and technical personnel often touch, generally referring to electrical connectors. That is, a device that connects two active devices to transmit current or signal. The connector is mainly used in the connection between the circuit and the circuit. It is the core basic element necessary for the electrical connection of the circuit system. The main application areas of the connector are smart homes and automobiles. , Communications, computers and peripherals, industry, military and aerospace. With the development, the application range will become wider and wider. They are basically used in various industries. There are many categories of connectors,M5/M8/M12/M16/M23/7/8" and other common connectors by size. including circular connectors, rectangular connectors, and stepped connections. The terminal block generally belongs to the rectangular connector, and the application range of the terminal block is relatively single. It is generally used in the electronic and electrical field, and is used for the internal and external wiring of PCB circuit boards, printed boards and power distribution cabinets.
②The connector is a positioning connector for connecting electronic circuits. It is composed of two parts, namely the connector and the connector. Under normal conditions, they can be completely separated. Therefore, the connector can also be called a connector in some occasions; a switch and a connector. The similarity of the plug-in unit is that it realizes the conversion purpose of the connected circuit through the change of the contact state of its contact pair. The essential difference is that the plug-in has only two states of insertion and removal, and the switch can realize the conversion of the circuit on its body. However, the connector cannot realize the conversion on the body, and the contact pair of the connector has a fixed corresponding relationship. Therefore, the connector can also be called a connector.
③Terminals, English name Terminal (terminal). It is an accessory product used to realize electrical connection, which is divided into the category of connectors in industry. Terminals are used to facilitate the connection of wires. They are actually a piece of metal enclosed in insulating plastic, with holes at both ends to allow wires to be inserted. Terminals can be divided into WUK terminal, European terminal series, plug-in terminal series, etc. Terminal. It is an accessory product used to realize electrical connection. It is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends to insert wires. Terminals are currently used. The most widely used are PCB board terminals, in addition to hardware terminals, nut terminals, spring terminals, rail-mounted terminal blocks, plug-in terminal blocks, European-style terminal blocks, and so on.
Electrical connector is abbreviated as connector, also called connector, which is a subdivision of electronic components and is mainly used for the connection between circuits. In industrial production, line connections can be said to be ubiquitous, so the scope of use of connectors is of course very wide, used in various industries.
Connectors are divided into many categories, such as rectangular connectors, circular connectors, stepped connectors, and so on. The terminal block is a type of connector, which is generally a rectangular connector. The use range of the terminal block is relatively simple, and it is generally used in the field of electronic and electrical, and used for the internal and external wiring of PCB circuit boards, printed boards and power distribution cabinets.
The use range of terminal blocks is increasing, and the types are also increasing. In addition to PCB terminals, the most widely used terminals include hardware terminals, nut terminals, spring terminals, etc. In the power industry, there are special terminal blocks and terminal boxes, all of which are terminal blocks, single-layer and double-layer , Current, voltage, common, 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.
