Terminal Blocks - Headers, Plugs and Sockets

In simple terms, a terminal block is an electrical connection device that assigns a common point for two or more wires. The terminal block functions to ensure a reliable, secure and safe connection between each wire in the circuit. Although terms are often used interchangeably, headers, plugs and sockets are all types of terminal blocks in their own right. They are commonly found in an industrial setting where it\'s essential to keep components in electrical communication with one another in the most efficient manner possible.

Headers

At the core of many electrical circuits are terminal headers. These are usually a series of plastic housing units containing a large number of metal contact pins. They have geometrical shapes such as square, rectangular or circular. Inside each housing unit, the pins are neatly arranged in columns and rows, with the underside of each pin having electric contact points. This design makes headers perfect for attaching multiple wires and highly conductive power sources to a printed circuit board (PCB).

Plugs and Sockets

Plugs and sockets are particular types of headers that are often used to make connections to external devices. Connecting plugs are connected to pins from the header and consist of two or more wires. At the other end of the wires sits a ‘socket’ - usually a female variant - which allows those plugs to slot securely into the socket. This type of connection ensures communication between the plug and socket is achieved with minimal risk and is often employed in electrical appliances, machines or control systems.

1899919 application field and working principle

At the most basic level, terminal blocks tend to comprise of three components: an insulator, a conductor, and a fastener. These are all used to complete an electrical connection between two or more wires. The most commonly used type of terminal block is the through-hole terminal block, which is found in digital and analogue circuits. It uses a solder to secure the wires to a terminal, which makes it ideal for applications such as power transfer or signal connections.

In more advanced types, such as spring connection or screw connection terminal blocks, the wires are connected using a mechanical-type fastening system. This is achieved either by pushing the wires into the contact points, or by tightening the terminals with a screwdriver or nut. The key benefit here being that the connection point is often re-enable, allowing it to be disconnected for maintenance or for upgrades. These types of terminal block are often used in appliances, medical scanning equipment or motors.

1899919 terminal blocks are specific types of terminal blocks, with their application field primarily in industrial and residential automation. Designed to achieve a reliable signal connection while using a minimum amount of space, 1899919 terminal blocks are a great choice for those looking for an efficient connection device for their system. The working principle remains essentially the same as all other terminal blocks, with the pins creating a reliable and secure connection, while a fastener keeps the wires firmly fixed in place.

When it comes to headers, plugs and sockets, 1899919 terminal blocks excel in using the most amount of space with the least amount of effort. Those looking to upgrade their system with an efficient connection device can rely on the performance and reliability of 1899919 terminal blocks.
