Why does the insulation of cold pressed terminals deteriorate?

I. Why does the insulation performance of the cold pressed terminal deteriorate? When the cold pressed terminals in the contact on the bad phenomenon, basically because of the external cable in the pressure, and the touching parts in the construction is very good, the function is also more stable. If the touching part is not reasonable in the construction, and the mold is not very stable, then the performance of the insulating part of the cold pressed terminal is sure to deteriorate, and eventually lead to the occurrence of bad contact. If the insulation performance is relatively good insulation parts, is to ensure that the placement of the touch parts, to ensure that the touch parts and the shell is insulated from each other, a lot of density is relatively large small cold pressed terminals, because the insulation parts are not very good, resulting in a lot of metal parts appear to be damaged, if there are harmful gases in the body, then the surface of the film there will be a conductive channel, and ultimately there will be a serious insulation of bad These phenomena are inevitable. Set up solid insulation is not very good, then basically does not play any insulation effect, solid insulation is to the touch parts can play a protective role, as well as the device in the positioning of the locking function, if the fixation is not very good, then the light will be an instantaneous power failure, and serious, it will lead to the entire product directly destroyed. In cold pressed terminals, contact force is one of the basic elements. If there is not enough contact pressure, the use of even the best conductive material is not helpful. Because, if the contact force is too low, there will be displacement between the wire and the conductive sheet, which will result in oxidized contamination, increasing the contact resistance and leading to overheating.
