1935860 Application Field and Working Principle

Terminal blocks are a board-level and cable-level electrical connection devices, which securely hold electrical wires in place, forming permanent connectivity in a circuit. They provide simple and effective ways to bridge the gap between different components, servers, and computers, and make the circuits possible. The following is an overview of terminal blocks - wire to board connectors, their application fields, and workings.

Application Fields

Terminal blocks - wire to board connectors, as their name suggests, are used in applications where the wires have to be connected to the boards. Examples include computers, household appliances, laboratory and medical equipment, aerospace and military-grade electronics, automotive, and industrial machines. They have been used to connect wires to a range of circuit boards, such as microprocessors, microcontrollers, DSPs, memory functions, power management, Ethernet controllers, and analog-to-digital converters. Their applications are far and wide, usually used in applications where the safety, performance, and reliability matters.

Working Principles

Terminal blocks - wire to board connectors are typically constructed from two main components: a connector part and a terminal part, held together to form a simple "snap & lock" system. The connector part is the body, and it is composed of a plastic shell and internal contacts which connect to the wires. The terminal part is the metal clip, which is usually used to secure and bind the wires together. The connectors are typically secured onto the board using U-nuts or screws.

The terminal block is connected to the board by inserting the connector part into the board’s receptacle and then fixing it in place with the terminal part, using the U-nuts or screws. When connected properly, the spring-loaded design of the connector will make a reliable electrical connection and maintain the connection even under the most demanding environmental conditions. The wires can also be taken apart from the board without any damage, making them perfect for prototyping or any adjustable, reconfigurable circuit.

Conclusion

As one of the most common electrical connectors, terminal blocks - wire to board connectors play a critical role in the connection between the wires and the boards, and in the manufacturing of various circuit boards. By allowing high-efficiency, reliable connections between the two components, they make the circuits possible and fulfill different application requirements in computers, household appliances, industrial machines, and other electronic devices.
