31107117 Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks are electrical connectors designed to connect two or more electrical lines or wires. They are equipped with two or more sets of terminals: a male terminal and a female terminal, and usually come in a variety of styles. The most popular types of terminal blocks are headers, plugs and sockets.

Header

Headers are two level or two row flat terminal blocks, widely used to interconnect wires in high density applications such as automotive, industrial, audio and telecommunications applications. Headers are normally designed to be mounted into a printed circuit board. Header connection styles include direct solder, crimp, IDC, and screws. These terminal blocks are designed so that wires can be quickly and conveniently connected, and are often used to link boards in a system together.

Plug

Plugs are rectangular terminal blocks with screw terminal connection styles. The two rows of plug terminal blocks are typically used to make male-to-female connections when connecting wires to other electrical or electronic components. These blocks generally provide a secure and efficient connection between wires, allowing their connections to be changed quickly and easily.

Socket

Sockets are single row terminal blocks that are designed to be mounted in housings, such as DIN or panel mounting rails. They are usually used to make female-to-male connections and can be quickly released or locked into position. These blocks are used in low level applications, such as the connection of light fittings, as well as in higher level applications, such as the connection of transformers.

31107117 Terminal Blocks - Application and Working Principle

Terminal blocks are used in a wide range of applications to make secure and reliable connections. These include the connection of two or more electrical wires, the connection of two or more electrical components, and the connection of two or more electrical circuits. The working principle of terminal blocks is simple: terminals are connected by inserting the correct type of connector into the corresponding female terminal, and tightening it to make a secure connection.Terminal blocks are designed with a variety of connection styles, such as screw, crimp, IDC, and direct solder. These connection methods offer a secure connection and can be used for both low and high voltage applications, including AC/DC power supply, control circuits, and audio/telecommunications.In addition to providing a secure physical connection, terminal blocks, such as headers, plugs, and sockets, also provide an electrical connection. The electrical connection between two terminals is made by joining the two opposite terminals with an appropriate electrical component, such as a resistor or capacitor, and then tightening the connection. This creates an electrical path between the two terminals, allowing current to flow from one terminal to the other.Terminal blocks are designed with safety features to protect from electric shocks. For example, they are designed with insulated materials to prevent electric current from flowing between terminals and human hands, and with shock-resistant clamps to prevent wiring from coming loose and causing electric shock.Terminal blocks are a reliable and cost-effective solution for connecting two or more wires, components, or circuits. They provide a secure physical and electrical connection, while also offering flexibility and a range of connection styles to suit a variety of applications.
