1955730000 Application Field and Working Principle

Terminal blocks, headers, plugs and sockets are components found in numerous electronic circuits and systems. These parts are used to secure and protect electrical and electronic connections. Terminals, plugs and headers also allow for adjustments to electronic and electrical components without having to disassemble parts of the system. In this article we\'ve outlined the application field and working principle of these components.

Terminal blocks

Terminal blocks are simply insulation-displacement connection (IDC) technology devices used to make quick, secure electrical connections. The idea is that two insulated wires simply need to be pushed into the contact and the insulation will automatically be pierced in order to create a connection. This technology saves time and labor costs, because the connection does not require additional stripping of insulation, crimping, or the use of any other type of special tool.

Materials used for Terminal Blocks

Terminal blocks are typically made from plastic or metal. Plastic blocks are usually made from polyamide or nylon and have a protective coating that prevents the contact from being damaged when operating in extreme temperatures. Metal blocks are often machined and are available in aluminium, brass, and nickel-plated copper. Because of their accuracy and insulation properties, nickel-plated blocks are often used in high-temperature applications.

Applications for Terminal Blocks

Terminal blocks can be used in a variety of settings such as motor vehicle wiring, power circuits, sensors and control systems in industrial equipment, and monitoring equipments in electrical distribution systems. In industrial settings, these components are used to make connections between motors, switches, and other devices. In more recent years, terminal blocks have also been used to create connections with printed circuit boards.

Headers, Plugs and Sockets

Headers, plugs and sockets are connectors used to make electrical connections between devices. Headers are generally rectangular in shape and have one or more pins, or contacts, protruding from the header housing. Plugs are sockets that are inserted into the header to make the connection. They have corresponding pins inserted into the socket that make an electrical contact with the header pins. Finally, sockets are headers that have a large number of poles that allow multiple connections to be made at once.

Materials Used for Headers, Plugs and Sockets

These parts are commonly made from plastic, metal and rubber. Plastic parts are usually injection molded from materials like nylon or ABS. Metal parts are made from brass, stainless steel, and aluminium. Rubber parts are usually made of synthetic rubber or thermoplastic elastomer.

Applications for Headers, Plugs and Sockets

Headers, plugs and sockets are used in a vast array of applications. Examples include automotive electrical systems, home appliance connections, LED lighting systems, power supply connections and more. In most cases, these parts are designed for quick and easy connections and disconnections of components, without having to disassemble parts or use special tools. They are also used in high voltage and extreme temperature conditions.

Working Principle of Headers, Plugs and Sockets

The working principle of these components is based on the concept of contact resistance. When a plug is inserted into a header or socket, the contact between the two parts creates an electrical connection. The header or socket must provide enough resistance to the current to ensure that a desired current is properly conducted through the connection. The contact resistance is also important to ensure that the connection will remain stably in place.

Conclusion

Terminal blocks, headers, plugs and sockets are commonly used in electrical and electronic circuits and systems. They provide a reliable, secure and adjustable connection that don’t need to be disassembled in order to be adjusted. These parts are typically made from plastic, metal, and rubber, and are used in almost any setting that requires connections between electronic components.
