Terminal Blocks - Headers, Plugs and Sockets

The 1637990000 terminal block is a multifunctional wiring component used to connect electrical wires to one another within a system. It consists of a basic block with two posts that can accommodate wires, plugs and other parts. The main purpose of 1637990000 terminal blocks is to provide a secure and reliable connection for power and signal transmission. They come in a variety of sizes and materials, and can be used for a variety of applications in a variety of industries.

Application Field

Terminal blocks are widely used in various industrial fields such as automotive, electrica, temperature controlling, and building lights. In automotive industry, terminal blocks are used to connect the wires for conducting electricity. In electrical engineering, the terminal blocks are used in connecting wires in various equipment. In building lights, the terminal blocks are used in cable wiring system to ensure safety. Moreover, terminal blocks are usually used in temperature controlling system. Temperature controllers use the terminal blocks to measure and control temperature and humidity parameters in a wide range of applications, such as air conditioning, medical equipment, metrology, environmental control and many more.

Working Principle

Terminal blocks rely on mechanical contact to achieve electrical communication. They have contact points that make contact with the wire, thus creating an electrical connection between the two points. This contact can either be positive or negative, depending on the type of terminal block.Positive contact terminal blocks use a spring loaded arm to secure a wire in place. The spring-loaded arm is driven into the contact post to securely fit a wire in place. Once the arm is pressed against the contact, it creates an electrical connection and power can be transferred.Negative contact terminal blocks use a sleeve to secure a wire in place. The sleeve is placed around a wire and pushed into the contact post to securely fit a wire in place. This type of connection eliminates the need for a spring loaded arm, as the sleeve securely holds the wire in place.

Conclusion

The 1637990000 terminal block is a multi-function wiring component used to connect electrical wires to one another within a system. It comes in a variety of sizes and materials, and can be used for a variety of applications in a variety of industries. Terminal blocks rely on mechanical contact to achieve electrical communication, and can have either positive or negative contact points. They are widely used in various industrial fields such as automotive, electrica, temperature controlling, and building lights.
