What is the clamping mechanism of the terminal

The principle and method of marking the terminal with alphanumeric symbols, the two end points of a single component are indicated by two consecutive numbers.

The middle terminals of a single element are indicated by numbers in natural increasing order. The same component group is prefixed with letters before the numbers, such as the letters U1, V1, W1, etc. that mark the three-phase communication system.

If there is no need to distinguish the same, the numbers 1.1, 2.1, 3.1 can be used to sign. Groups of similar components.

The mark of the electrical terminal connected to a specific wire. The compression organization of the terminal is the organization that generates pressure between the wire and the conductive strip. Only when a satisfactory pressure occurs can it ensure a low contact resistance and form an outstanding connection. Therefore, the reliability of the compression organization directly affects the connection of the wires. Good or bad.

For threaded terminals, screws, copper posts and pressure plates are important components of the compression organization; for non-threaded terminals, the tension spring or tension spring card is an important component of the compression organization.

Without threaded terminals, the compression organization is mainly tension springs, so the selection of tension springs is very important. It is necessary to ensure that there is a satisfactory contact pressure and to ensure that the wires will not be damaged by overheating. The tension spring terminals are now relatively reliable without threads. Terminal.

When entering the wire, the tension spring can be pressed by a push block or a screwdriver. After entering the wire, loosen the tension spring, use the tension of the tension spring to tightly press the wire, and generate a satisfactory contact pressure, and then use the edge of the tension spring Strangle the wire so that it will not loosen or be pulled out artificially.
