Terminal Blocks - Headers, Plugs and Sockets 5452198 Application Field and Working Principle

Terminal blocks are connection components used to terminate or electrically connect conductor wires and cables. They are important components in low-voltage electrical circuits and enable a convenient and reliable connection of conductor wires. Terminal blocks can be broadly classified into three types - headers, plugs and sockets. Terminal blocks type 5452198 are headers.

Headers are fixed connection components which are installed directly onto a printed circuit board. In comparison to their counterparts, plugs and sockets, terminal blocks of this type are also characterized by a high degree of mechanical robustness. This can be achieved through their robust plug-in connections that do not loosen after long-term use. They are used in applications such as factory automation, process control, machine equipment, power supply, communications control, welding and electrical automation.

Working Principle of 5452198 Terminal Blocks

5452198 terminal blocks feature plug-in design. The contacts on the terminal blocks are a combination of terminals with insulation displaceable connectors andare wired directly onto the PCB. An insulation displacement connection (IDC) is an electrical connection strategy for connecting two conductive materials. It works by precisely positioning two conductive materials, a wire and a terminal, in such a way that a thin metal rivet displaces the insulation around the wire and allows contact to be made. This allows for easier and faster installation of electrical components as no additional tools or solder are required.

The core of this terminal block type consists of a u-shaped contact spring which contacts the inserted PCB. This contact spring is made from a tin coated spring steel in order to ensure a stable, reliable and constant contact over time. After installing the two terminals on the PCB using solder, the cable is inserted into the header. The steel contact spring is shaped so that it applies a spring force, pushing up against the conductor wires to create a secure electrical contact.

The conductor is securely held in place in the header by the action of two sprung contact arms in the contact chamber. The two contact arms that are pressed against the conductor are made from tin-plated brass. The contact surfaces of the contact chamber are wider than those of the conductor wires, ensuring maximum contact pressure and secure contact.

Summary

Terminal blocks can be broadly classified into three types – headers, plugs and sockets – and these terminal blocks type 5452198 are headers. Headers are fixed connection components which are installed directly onto a printed circuit board and are characterized by a high degree of mechanical robustness. The core of this terminal block type consists of a u-shaped contact spring which contacts the inserted PCB, with two sprung contact arms which are pressed against the conductor to create a secure electrical contact. This type of terminal block is used for a variety of applications such as factory automation, process control, machine equipment, power supply, communications control, welding and electrical automation.
