Terminal blocks, also known as terminal boards or strips, are electrical connectors typically used to connect wiring on printed circuit boards and other electrical systems. The terminal blocks are particularly useful in applications where flexibility is required, such as on assembly lines where certain components must be replaced quickly. The other main advantage of terminal blocks is that they are usually made from robust materials for long-term applications.

The main types of terminal blocks – headers, plugs and sockets – each have a different purpose. Terminal blocks can be further categorized according to their function and usage.

headers

Header blocks are most often used in manufacturing and wiring, especially in electronic circuits. When used as part of the electrical system during the wiring process, they help to organize the circuit’s wires, and can also be used to route signals. They are typically made of high-quality economic thermoplastics.

Plugs

Plugs are typically used to make quick connections through the wiring of two or more components. These connectors are widely used in the manufacture and assembly of printed circuit boards. They are also suitable for connecting vibration sensors, signal connections, motor connectors, actuator connections, and other cable companions.

Sockets

Sockets are a type of terminal block with pins that enable it to connect wires easily. Depending on the specific application, they are either soldered or force-fitted onto the end of a cable for easy connection. In some cases, they are used to couple sections of a connector or jumper cable. They are also commonly found in electric outlets and are used as interconnections in some types of power supply systems. These connectors are available in many sizes, shapes, and material specifications, and they are frequently used in home appliances, electronic devices, and other wiring systems.

5452447 Applications

Terminal blocks have a wide range of applications in the electrical and engineering industries. They are used to provide permanent wiring of components within an integrated system, and are also commonly used as a method of connecting modules to printed circuit boards. Other applications include wiring external cables to the electrical system, connecting multiple cables within an assembly, or connecting multiple electronic circuits, sockets, and plugs.

Working Principle

The working principle of a terminal block is relatively simple – a terminal block allows signals or electrical power to be transported between two or more electrical components. The terminal block itself consists of two or more metallic or plastic components that have an electrical contact on one end. The other end of the terminal block is where the cable, connector, or wire is attached, and it is usually securely fixed to the electrical system.

When the two components connect, electricity flows between them through the terminal block. This is also known as a “continuity” connection, and it is the main working principle of terminal blocks. This process is used in all types of wiring from automotive, consumer electronics, industrial automation, and more.
