Introduction to Terminal Blocks - Wire to Board

Terminal blocks are a type of electrical connector typically used in the industry to securely and rapidly connect wires between two devices in a process. When it comes to electrical wiring, terminal blocks are the best option for connecting multiple wires at once. Terminal blocks come in a variety of models and sizes to fit the needs of a variety of applications. Terminal blocks are broadly categorised into two types: the wire to board and board to board types. The most common type of terminal block is the wire to board terminal block, which allows the connection of multiple wires to a board, such as a printed circuit board. This type of terminal block is designed to simplify the management of complex wiring arrangements and enables the use of power, data and control signals in a single connection.The wire to board terminal block is a two-component assembly, which consists of a housing and the contact itself. The housing secures the contact within the board while the contact provides the electrical connection. These terminal blocks are constructed out of high-grade metal, plastic or other materials depending on the application and application area.

A-TB381-ED22SB: Overview and Features

The A-TB381-ED22SB is a type-of wire-to-board terminal block manufactured by COMTEC Corporation, Inc. This terminal block is a 3.81mm PITCH, 22 way 2.70mm HIGH 2.54mm HOLE PITCH Panel Assembly. It comes with a high-temperature rating of 105°C and is a UL 94V-0 approved product. It has a wide range of operating voltages from 72VAC to 392VAC and a high current rating of 15A per terminal. It also has excellent dielectric strength, with a rated voltage of 1500VAC and a rated impulse withstand voltage of 6kV.

A-TB381-ED22SB: Application Field and Working Principle

The A-TB381-ED22SB is used in a variety of electrical applications, including industrial machinery, electrical control, automotive electronics, telecommunications, medical electronics, and more. This terminal block is designed for increasingly demanding applications, including high-voltage and high-current applications, and can handle currents up to 15A. The operating principle of the A-TB381-ED22SB is quite straightforward. The terminal block body is constructed to house and electrically connect the various wires together with the pluggable contacts. The contacts are inserted into the block by a small spring-loaded device which is operated by a cam. Once the wires are inserted, the contacts are then locked into place mechanically and electrically. The contact has a notch at the top, which accommodates the wire insulator, creating environmental protection against dust particles and other foreign particles. The contact also has a spring back feature, which allows the contact to vibrate with the wire while not affecting its electrical connection. The contact also provides a secure and solid electrical connection which is reliable and hard wearing.

Conclusion

The A-TB381-ED22SB wire-to-board terminal block is an excellent solution for high-current and high-voltage electrical connections. It is an excellent choice for a wide range of applications, including automotive electronics, industrial machinery, electrical control, telecommunications, and medical electronics. With its high temperature rating, UL94V-0 approved rating, and excellent dielectric strength, the A-TB381-ED22SB is an ideal solution for reliable and safe wiring connections.
