On the terminal block, we're actually on the insulator, the effect of which is actually keeping the touch in the right direction. In fact, you can touch and touch yourself. Insulation between touch and case is done.

This is also why, for the insulator of the terminal block, it should actually have better electrical function, actually should have better mechanical function and process forming function. Especially with the wide application of high-density and miniaturized terminals, the useful wall thickness of insulators will become thinner and thinner.

In terms of the insulating material on the Cord End Terminals, as well as the precision and molding process of the injection mold, in fact, stricter requirements are put forward due to the appearance of the insulator or the presence of more metal residues inside, its appearance dust and flux are also Relatively simple, one-time pollution and dampness.

The terminal is an ion conduction channel formed by the separation of organic matter and the fusion of the harmful gas adsorption film and the external water film. In addition, the terminal is faced with hygroscopicity and fungal properties, so it becomes the aging of the insulating material, etc. There are many reasons. For the terminal block, it is generally possible to have poor insulation.
