First, distinguish the concept of "connector", "terminal" and "connector"
①Connector, namely CONNECTOR. Also called plug-in connector. It is a component that electronic engineering and technical personnel often contact. Also known as connectors, plugs and sockets in China. Generally refers to electrical connectors. That is, a device that connects two active devices to transmit current or signal.
②The connector is a positioning connector for connecting electronic circuits. It is composed of two parts, namely the plug and the connector. Under normal conditions, they can be completely separated. The similarity between the switch and the connector lies in the contact state of the contact pair. The change to achieve the conversion purpose of the connected circuit, and the essential difference is that the connector has only two states of insertion and removal. The switch can realize the conversion of the circuit on its body, while the connector cannot realize the conversion on the body. , The contact pair of the connector has a fixed corresponding relationship, so 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 classified as a connector in the industry. The terminal block is used to facilitate the connection of the wire. It is actually a piece of metal enclosed in insulating plastic, with holes at both ends, which can be inserted into the wire. Terminals can be divided into WUK terminal, European terminal series, plug-in terminal series, etc.
2. Distinguish "connectors", "terminals" and "connectors" from the scope of ownership
①"Connector=Connector" is the first category, and the terminal block is only one of the "connector" categories
What is the difference between a connector and a connector?
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 real life people often refer to the same thing vaguely.
②The terminal is part of the connector. Connector is a general term. In fact, the connectors we commonly see usually include two parts: housing and terminal. Housing is mostly plastic, which plays a protective role, and the terminal is metal, which is universal.
③In the electrician and electrical fields:
Connectors, connectors, and connectors are the same product. In layman's terms, it is the kind of stuff that can be quickly connected to the male and female heads with one hand or one screw without tools.
Terminals are commonly understood as the kind of stuff that requires tools such as screwdrivers and cold press pliers to connect two stuff together. They are generally used for power input and output. English name Terminal (terminal).
3. Distinguish the actual applications of "connectors", "terminals" and "connectors"
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 single, and it is generally used in the electronic and electrical field, and used for 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 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, "connector", "terminal", and "connector" are different application manifestations that belong to the same concept, and are commonly called according to different practical applications.
