Terminal Blocks - Headers, Plugs and Sockets

Terminal Blocks are mechanical connectors which securely electrically connect two or more wires. By connecting wires to a common electrical point, the terminal blocks are used to build electrical circuits. Primarily used in the electronic systems and machine tools industries, terminal blocks are constructed from three parts – plated steel lugs, a metal body, and springs. Terminal Blocks are found in a variety of formats and sizes, all of which are designed to suit specific current, voltage, and wire gauge requirements. Common Terminal Blocks include headers, plugs, and sockets.

Headers

The header is a terminal block with no spring, and is typically used as a mounting base for a PCB (Printed Circuit Board). This block is constructed from two components – the header itself and the housing. The header is a set of electrical terminals that are divided into two sections; an upper section, which is mounted on the headers and an underside section which contains the contacts. The header housing is a plastic moulding which fits over the header terminals and connects to the board, enclosing both the upper and underside sections.

Plugs

The plug is a small terminal block which fits into a header. Commonly referred to as the male connector, the plug typically has two to three rows of terminals. The Plug is generally composed of a shell and a contact terminal. It is typically installed onto the PCB, and is used to connect the board’s circuitry to external circuitry.

Sockets

The socket is the female counterpart to a plug. It typically has two to three rows of terminals and can accommodate most types of cables, depending on the need. Generally composed of a shell and contact terminal, the Socket is usually installed onto the PCB and is an excellent choice for internal wiring.

1612040000 Application Field and Working Principle

Terminal Blocks are used in a wide variety of industries and electronic applications. They are most widely used in the industrial automation, home appliance, medical device, automotive, and telecommunications sectors as well as in energy distribution systems. Terminal Blocks are also popular for simple wiring applications such as lighting systems, emergency systems, clocks, transformers, etc. Terminal blocks can be fitted to separate and protect electrical components and wires, as well as to expand an existing electrical system. They are designed to provide insulation and protection for wires in the form of an enclosure or a connector, thus providing connection points for the wires and components. The Working Principle of Terminal Blocks is based on the contact between the metal lugs and the springs on either side of the block. When a wire is inserted into a terminal block, the lugs force the spring to compress, thus making an electrical connection. This connection is then carried on to other components or systems. The connection is held in place due to the fact that these springs are designed to hold the lug firmly in place when connected. The insulation and metal lugs inside the Terminal Blocks also prevent short circuits and ensure reliable electrical connections. Terminal Blocks are an essential part of any electrical system and provide a secure point of connection for wires and components. Their ability to be scaled for different electrical requirements, as well as the insulation, robustness, and reliability they offer make them an ideal choice for a wide variety of applications.
