Terminal blocks are an accessory product used to achieve electrical connections, and are classified as connectors in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks has gradually increased. With the development of the electronics industry, the use of terminal blocks has become more and more diverse. In addition to PCB board terminals, the most widely used ones include hardware terminals, nut terminals, spring terminals, and so on.

Definition

Terminal blocks are used to facilitate the connection of wires. They are actually a piece of metal sealed in insulating plastic. There are holes at both ends for inserting wires, and screws for tightening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and can be disconnected at any time without welding or twisting them together. It is very convenient and fast. It is also suitable for interconnecting a large number of wires. In the power industry, there are special terminal blocks and terminal boxes, which are all terminal blocks, single-layer, double-layer, current, voltage, ordinary, breakable, etc. A certain crimping area is to ensure reliable contact and ensure that enough current can pass.

Classification

Terminal blocks can be divided into , European terminal block series, plug-in terminal block series, transformer terminal block, building wiring terminal, fence terminal block series, spring terminal block series, track terminal block series, through-wall terminal block series, photoelectric coupling terminal block series, 110 terminals, 205 terminals, 250 terminals, 187 terminals, OD2.2 ring terminals, 2.5 ring terminals, 3.2 ring terminals, 4.2 ring terminals, 2 ring terminals, 6.4 ring terminals, 8.4 ring terminals, 11 ring terminals, 13 ring terminals, flag-type series terminals and sheath series, various types of ring terminals, tubular terminals, terminal blocks, copper strips and iron strips (2-03, 4-03, 4-04, 6-03, 6-04), etc.
