How to distinguish from attribution

① "Connector = connector" is the first category, and the terminal block is only one of the "connector" category. The connector is the connection between lines; The connector is the connection between line, board and box. In practical application, it is often classified into one category.
② The terminal is part of the connector. Connector is a general term. In fact, connectors commonly used by us usually include two parts: housing and terminal. Housing is mostly plastic, which plays a protective role, and terminal is metal, which plays a conductive role.
③ In the electrical field:

Connectors, connectors and connectors are the same product. Generally speaking, it means that the male and female heads can be quickly connected by inserting or screwing without tools.

The wiring terminal, popularly understood, is the kind of thing that requires tools such as screwdriver and cold pressing pliers to connect two things together. It is generally used for power input and output. English name terminal.

How to distinguish from practical application

Electrical connector, also called connector for short, is a subdivision of electronic components and is mainly used for the connection between circuits. In industrial production, line connection can be said to be everywhere, so the scope of use of connectors is of course very wide, applied in various industries.

Connectors can be divided into many categories, such as rectangular connectors, circular connectors, stepped connectors, etc. terminal strip is a kind of connectors, which generally belongs to rectangular connectors. The scope of use of the terminal strip is also relatively simple. It is generally used in the electronic and electrical field, for internal and external wiring of PCB circuit boards, printed boards and distribution cabinets.

More and more terminals are used, and there are more and more types. At present, in addition to PCB board terminals, hardware terminals, nut terminals, spring terminals, etc. are most widely used. In the power industry, there are special terminal strips and terminal boxes, all of which are wiring terminals, single-layer, double-layer, current, voltage, common, breakable, etc.
