Terminal Blocks - Headers, Plugs and Sockets 0395232802

Terminal blocks are an electro-mechanical device which mechanically secures, and electrically connects electrical wiring. Generally they are used to connect two or more wires together and provide an electrical connection in order to join two or more circuits. This process is also referred to as the act of “jumpering”. Terminal blocks are available in a variety of configurations, from plugs to headers and from sockets to jumpers.

Application Field

Terminal blocks are applied in a wide variety of applications, ranging from industrial processes to consumer electronics. Industrial processes involve the use of terminal blocks mainly as a means of isolating wiring from the control software, allowing it to have its own circuit designs and its own power circuit. Consumer electronics such as audio/video and security systems can also benefit from the use of a terminal block, as it allows complex systems to be wired with minimal effort.

Working Principle

The basic working principle of a terminal block consists of two parts - the base terminal block and the terminal strip. The base terminal block is securely fixed onto an insulated surface or panel. It acts as a point of connection for all wiring, similar to a foundation block. The terminal strip then connects to the base terminal block and provides the mechanical and electrical connection between circuits. The terminal strip has a series of connection points which wires can be secured to.

The electrical connection between the wires and the terminal strip is made using either a screw or terminal block connector. A screw connection is made by inserting the bare end of a wire into a hole in the terminal strip. The screw is then tightened, securing the wire and creating an electrical connection. A terminal block connector connection is made using small plastic pieces with metal contacts. Wires are secured in the plastic blocks, and these blocks are then inserted into the holes in the terminal strips. The contact points then make the electrical connection, securing the wires and the terminal strip.

In addition to the secure mechanical and electrical connection, a terminal block can provide other benefits, such as polarity protection and short-circuit protection. In both of these cases, the current of the connection is secured and protected from any accidental or intentional damage. In polarity protection, special terminals are provided which ensure that the positive and negative connection points cannot be crossed, avoiding any potential accidental shorts. In the case of short-circuit protection, special terminals are designed to ensure that the current is always routed correctly, protecting the wires from high current or voltage damage.

In conclusion, terminal blocks are an essential element in any electrical system, as they provide a secure and reliable means of connecting two or more circuits. With the variety of terminal blocks available, from plugs to headers and sockets to jumpers, users can easily find the right configuration for their application. In addition, with the use of polarity protection and short-circuit protection, users can trust that their electrical connections are safe and secure.
