Conductive bus board for punching process in liquid heating PTC (Positive Temperature Coefficient)

The utility model provides a conductive bus board for a punching process in liquid heating PTC (Positive Temperature Coefficient), the electrode slices of a heating unit are connected, the claws are contacted with the electrode slices to conduct current so as to realize heating of the PTC, and the whole copper electrode is put into a mold in an injection molding process, so that the whole copper electrode is formed. The plastic fixing frame and the whole copper electrode are combined into a whole through the injection molding process, high voltage is directly and physically isolated, safety and reliability are achieved, and the problems of poor production efficiency and poor overall position degree are solved; the copper electrodes are electrified with high voltage during working, each copper electrode is physically isolated, and meanwhile, the copper electrodes are isolated from other parts of the PTC, so that absolute insulativity and safety are ensured; redundant copper pole pieces are removed at the punch
