Terminal Blocks - Headers, Plugs and Sockets

1618040000 Application Field and Working Principle

Terminal blocks are classified as headers, plugs and sockets according to their shape. Terminal blocks are widely used in many areas, such as rail transportation, automation, aviation, electronics, military, communication and medical equipment. The most common type is the 2.54mm pitch type, and the contact terminal is made of copper, with good electrical, thermal and mechanical properties.

The Working Principle of Headers

Headers are mainly used for wiring connection of electronic products during equipment installation. Generally, the bottom of the header has two rows of heads or directly has holes and nuts for mounting on the PCB board. Inside the header, there are two rows of contacts connected to each other. Each contact is usually made of a silver plated or tinned copper shell, and a stainless steel spring body is hinged inside, which could be used to make electrical connection with flat pins or other terminals. When in use, the internal spring will push and press the connected terminals tightly to make the best electrical contact.

The Working Principle of Plugs and Sockets

Plugs and sockets are mainly used as terminals for wiring connection of electronic products during equipment installation. Generally, a plug or a socket is a metal terminal. A row of metal shells of the plug or socket can be crimped on the wire and can be connected firmly. The contact terminal has teeth for locking and ensuring secure connection. When the plug is inserted into the socket, the teeth will be engaged to ensure stable connection. There is also a cold-pressed terminal inside, which can connect the plug and socket firmly. The cold-pressed terminal has a good electrical and thermal conductivity, so the plug and the socket have low contact resistance.

Conclusion

Terminal blocks are widely used in many areas, such as rail transportation, automation, aviation, electronics, military, communication and medical equipment. The most common type is 2.54mm pitch type, and the contact terminal is made of copper. Headers are mainly used for wiring connection of electronic products during equipment installation and the internal spring pushes and presses the connected terminals to make the best electrical contact. Plugs and sockets are mainly used as terminals for wiring connection of electronic products during equipment installation, and when the plug is inserted into the socket, the teeth will be engaged to ensure stable connection and lower contact resistance.
