Introduction

Terminal blocks - headers, plugs and sockets are widely used in the proper instrumentation, at an exact point. The 1891ed electrical terminal block is invented to solve the problem of soldered wire splicing. It is used to connect two or more electrical wires by clamping them together without soldering. This connection established is durable, secure and easy to maintain thereby making it the preferred choice when digital technology is used for application.

Applications

Terminal blocks are used in many different industrial and electrical applications such as instruments and electronic measuring systems, automation and control systems and power distribution. It is ideally suited for use in vertical or horizontal profile wiring applications and for production line testing. Terminalblocks are used in system like any other component. Terminal blocks are installed in the right place for the desired function. The wider application areas vary from terminal blocks used in a truck, a telephone exchange, computers, electronic devices, lighting systems, office machines to safety and security system.Furthermore, there is an extensive range of stand-alone terminal blocks in the industry which allows user to for quickly select and install electricity in any project. This stand-alone modular terminal block system enables the user to connect and disconnect energy quickly while improving safety of the system.

Working Principle

Terminal blocks consist of two inner pieces which have a metal contact. These contact halves slide in and then lock together to clamp the cable and produce the electrical connection. After connecting the two connection parts, the lower part is tensioned. A special contact spring is mounted, which is operated by a hexagonal shaft. Its function is to apply force to create a spring tension . This ensures a secure electrical connection between the cable and the contact elements. The current rate of an electrical connection from a terminal block considerably depends on the design. Depending upon the terminal block current rating, user should take an appropriate selection of terminal blocks.

Conclusion

Terminal blocks - headers, plugs and sockets are important and widely used tools in the electronics industry. They provide an efficient way of connecting electrical devices without having to solder the connection. They are safe as long as the correct type of terminal block is used. The main working principle is the tension between the two connection parts that is created by the contact spring. Accordingly, the electrical connection quality as well as its current rate really depends on terminal block design.
