Terminal blocks, or sometimes referred to as terminal strips, are specialized electrical or electronic connectors widely used in a variety of applications. They provide an interface between electrical wiring and equipment. Headers, plugs, and sockets are the three types of terminal blocks commonly used in applications. This article will discuss the application field and working principle of 1723719 terminal blocks - headers, plugs, and sockets.

Application Fields

1723719 terminal blocks - headers, plugs, and sockets - are found broadly in lighting control, signaling, and grounding applications. In residential and industrial lighting, terminal blocks are used to provide the connection between electric wires and lighting components, such as light bulbs, drivers, and CFLs. They also serve as a junction for specialized lighting control systems where switches, sensors, and timers can interact with one another.

Terminal blocks are widely employed in signal transmission applications. They are used to route and connect signals between transducers and amplifiers, while also providing protection against noise, static, and other elements that can cause interference.

Moreover, they are also employed in grounding applications. In electric equipment, terminal blocks provide the mechanical connection and conductive surface that are required to ground the components. This helps protect user safety, as the ground will remove any electrical shock.

Components of a Terminal Block

1723719 terminal blocks consist of two components - the housing and the contacts. The housing is an insulative plastic molded piece that contains the internal contacts, while the terminations are metal components designed to hold the wires.

The contacts serve three functions - it provides the path for electrical current, it accepts the wiring, and it spaces the contacts apart. The housing is the structure that supports and separates the contacts, and its structure is designed to provide reliable and secure assembly.

Working Principle

1723719 terminal blocks are engineered to make the connection between wires and electrical equipment. Initially, the wires are brought into the terminal block through openings in the housing. Inside the housing, the wire is clamped by a metal contact, thus making an electrical contact. This type of connection is also known as a “screw-clamp” connection.

To secure and ensure the connection is sound, a mechanical clamping force is applied when the wire is inserted into the contact. This force compresses the conductor strands and helps prevent them from coming loose while also providing superior electrical contact. Once the connection is completed, the force supplied by the contact is not required to maintain the connection.

The housing is cut into segments, which act as insulation barriers. This separation ensures that direct contact is not established between the different terminals on the same block, thus reducing the risk of short circuits.

Conclusion

1723719 terminal blocks - headers, plugs and sockets - are important components found in a variety of applications. They serve as an connection interface between electrical wiring and equipment, and are found in lighting control, signaling, and grounding installations. The terminal blocks consist of two components - the housing and the contacts - and the working principle is based on “screw-clamp” connection.
