Transformer Terminal Blocks

The terminal block 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 for the wire to be inserted. There are screws for fastening or loosening, such as two wires. Sometimes Need to connect, sometimes need to disconnect, then you can use the terminal to connect them, and can be disconnected at any time, without having to weld or twist them together, it is very convenient and quick. And it is suitable for a large number of wire interconnections. In the electric power industry, there are special Terminal Blocks and terminal boxes, all of which are connected terminals, single-layer, double-layer, current, voltage, ordinary, breakable, and so on. A certain crimping area is to ensure reliable contact and to ensure that sufficient current can pass.

Product application: Mainly used in lighting, communications, security and other industries. The application industries of plug-in terminals are the most dominant, such as frequency conversion, vandal-proof, numerical control panels, access controllers, sensors, PLCs, instruments, power supplies, and servo drives. These application industries have common to plug-in terminals. The requirements are: the insertion and extraction force must be stable, the contact resistance must be small, and a certain life and fatigue must be met, so the requirements for the hardware shrapnel material are higher. This requires product designers to have certain experience in structure and material selection. The main applications of barrier terminals are: power supplies, relays (especially double-layer terminals), frequency converters, elevator industry (less), air conditioners.
