What Is The Clamping Mechanism For Terminal Blocks?
The clamping mechanism of the terminal block refers to the mechanism that generates pressure between the wire and the conductive strip, and its reliability and design directly affect the quality of the wire connection. The following is a detailed introduction to the clamping mechanism of the terminal block:
1、 Definition and Function
The main function of the clamping mechanism is to ensure a good electrical connection between the wire and the conductive strip. By applying sufficient pressure, the contact resistance can be reduced to ensure stable transmission of current.
2、 Type and Structure
Depending on the type of terminal, the clamping mechanism also varies. It is mainly divided into the following two categories:
Threaded terminal clamping mechanism: usually composed of screws, copper columns, and pressure plates. When tightening the screw, the tightening force of the screw acts on the clamping piece, and through the principle of automatic step locking, the friction force of the thread gradually increases, achieving screw self-locking and ultimately clamping the wire onto the conductive strip.
Non threaded terminal clamping mechanism: mainly relies on springs or spring cards to apply pressure. When entering the wire, you can press the spring with a push block or screwdriver, release the spring after entering the wire, use the spring's pulling force to tightly press the wire, and then use the blade of the spring to fix the wire to prevent it from loosening.
3、 Importance
The reliability of the clamping mechanism directly affects the quality of the wire connection. If the clamping force is insufficient, it may lead to an increase in contact resistance, causing problems such as heating, arcing, and even circuit failure in severe cases.
In summary, the clamping mechanism of terminal blocks is an indispensable part of electrical connections, and its design and selection need to be comprehensively considered based on specific application scenarios and wire specifications.
