Terminal Blocks - Wire to board 1771101 application field and working principle

Terminal blocks, also referred to as wire to board connectors, are devices that serve to connect electrical circuits with a variety of signal types. Since its inception in the early days of the Industrial Revolution, the design and utilization of terminal blocks has remained fairly consistent; however, the technology continues to evolve, offering more sophisticated solutions for industrial and commercial applications. This article will explain the application field and working principle of the 1771101 type of terminal blocks, which are widely used for transferring signals of different types.

Application Field

Terminal blocks are widely used in the electronics industry for connecting wires to circuit boards and other electrical equipment. When connecting wire with a terminal block, the wire is typically inserted in a low-resistance socket that may either be spring-loaded or screw-tightened, depending on the type of terminal block. Compared to soldering, the use of terminal blocks can reduce installation time and labour cost.1751101 type of terminal blocks are suitable for applications that require a higher degree of performance, reliability and safety, such as in medical devices, process control systems, power supplies, network communication systems, etc. Their main advantage against other connector systems is that they are easy to install and maintain, and offer a secure connection to both the wire and the circuit board.

Working Principle

The 1771101 terminal blocks are made up of a shell or body and an internal connector, which is usually made of metal or plastic. The shell is designed to provide mounting points on the circuit board or panel and keep out dust and moisture. The internal connector is made up of two parts: the plug and the socket. The plug is made from metals such as brass or copper and provides multiple contacts for connecting wires. The socket is made from a conductive material such as a ceramic, which ensures efficient electrical connection with the plug.When a wire is inserted in the terminal block’s socket, the plug’s contacts will mate with the socket’s contacts. This establishes a secure electrical connection between the wire and the circuit board, where the expanded current will flow. As well, the spring-loaded contacts maintain a low contact resistance, which ensures a reliable connection over time.

Conclusion

Terminal blocks are an efficient and secure way of connecting wire to circuit boards, offering a reliable and hassle-free connection for various types of signals. 1771101 type of terminal blocks use a plug and socket design for reliable electrical connections, and can be employed in a wide range of applications, such as medical devices, process control systems, power supplies, and network communication systems.
