When the cold-pressed terminal has bad contact, it is basically because there is pressure in the external cable, and the touch part is very good in structure and its function is relatively stable. Why does the insulation performance of cold-pressed terminals deteriorate?

In cold-pressed terminals, contact force is one of the basic elements. If there is not enough contact pressure, no matter how good the conductive material is, it will not help. Because if the contact force is too low, there will be displacement between the wire and the conductive sheet, resulting in oxidation pollution, increasing the contact resistance and causing overheating.

　　 If the structure of the touch part is unreasonable, and the mold is not very stable, then the performance of the insulating part in the cold-pressed terminal is definitely degraded, which will eventually lead to poor touch.

If it is an insulating part with relatively good insulation performance, it can ensure the placement of the touch part and ensure that the touch part and the shell are insulated from each other. Many small cold-pressed terminals with relatively high density are because the insulating parts are not very good. Many metal components are damaged. If harmful gases appear in the body, there will be conductive channels on the surface of the film, and severe poor insulation will eventually occur. These phenomena are inevitable.

If the solid insulation is not very good, it will basically not have any insulation effect. The solid insulation can protect the touch parts and lock the positioning of the device. If the fixing is not very good If it is light, there will be an instantaneous power failure, and if it is serious, it will cause the entire product to be directly damaged.
