Terminal Blocks, Headers, Plugs and Sockets

Terminal blocks, headers, plugs and sockets are used in various fields of industry, such as electrical, electronic and network engineering. They are also common components in many machines. They all have different shapes and sizes, but all have a common purpose: they are used to make the connection between two or more wires or cables, and to make the assembly easier for an electrical engineer.

What are Terminal Blocks?

Terminal blocks are devices used to connect two or more wires or cables. They are typically used when a large number of wires need to be connected in a small space. Terminal blocks come in a variety of shapes and sizes, and some include additional components such as jumpers or grounding lines. The most common types of terminal blocks are barrier-type terminal blocks, which use an internal “barrier” to help protect the connection from damage, and screw-type terminal blocks, which use a screw-like mechanism to securely clamp the wires.

What are Headers and Plugs?

Headers and plugs are primarily used in electronic and network engineering applications. A header is a type of electrical socket that has one or more pins that receive electrical signals; however, the connectors on the pins are not necessarily connected to each other, as a cable or board may have multiple, different types of pins. A plug is a type of connector used to connect two wires, cables or boards together. Plugs are inserted into either side of a header and secured with a latch or screw.

What are Sockets?

Sockets are similar to plugs, but instead of being used to connect two wires or cables together, they are used to connect a device to a power source. Like plugs, sockets are designed to be inserted into a header or power port and secured with a latch or screw.

1975888 Application Field and Working Principle

Terminal blocks, headers, plugs and sockets are used in a variety of application fields, including telecommunications, computers, industrial equipment, and home electronics, among others. The working principles of these components vary according to the purpose they serve. Terminal blocks generally provide mechanical and electrical support to wires and cables while protecting them from overvoltage and short circuits. Headers and plugs are mainly used for data transmission between two or more devices, while sockets are primarily used to connect devices to a power source.
