It Is Dangerous If The Terminal Block Is Not Fixed Properly

First of all, we should pay attention to the fact that the insulator on the terminal not only plays an insulating role, but also provides accurate alignment and protection for the protruding contact parts to a large extent. At the same time, to a large extent, it also has installation positioning and locking fastening The function fixed on the device.

If the terminal is not fixed properly, it will directly affect the contact reliability. At this time, to a great extent, it will cause instantaneous power failure. In fact, it means that the product disintegrates. If it is disassembled, it means that the terminal is in the plug-in state. Because of the material, design, process and other reasons, the structure will be unreliable, that is, the abnormal separation between the plug and socket, and between the pin and the jack will result in serious consequences of the interruption of power transmission and signal control of the control system.

The poor fixation of the terminal, that is, the design is not reliable, and then, it is because of the wrong material selection. Moreover, it is because of the improper selection of the molding process, or due to the heat treatment, mold and its assembly and welding process quality is relatively poor, and the assembly is not in place, which will directly cause the poor fixation.

In addition, when it comes to the poor fixation of the terminal, that is to say, the appearance is not good due to peeling, corrosion, bumping on the coating, or the flash or fracture of the plastic shell, or the rough processing and deformation of the contact parts.

Finally, the poor fixation on the terminal, that is, the poor positioning and locking fit size, poor consistency in processing quality, and large total separation force, will cause poor interchangeability, which is actually a common disease and frequently occurring disease. These kinds of faults are usually found and eliminated in time in the process of inspection and use of terminal blocks.
