Chip mechanism and bridge rectifier

The utility model discloses a chip mechanism and a bridge rectifier, and relates to the technical field of rectifier bridges. The chip mechanism comprises an electrode assembly, a first insulating part and a second insulating part, the electrode assembly comprises a first electrode layer and a second electrode layer, the first electrode layer is attached to the second electrode layer, the first insulating part penetrates through the first electrode layer and extends into the second electrode layer, and the second insulating part penetrates through the second electrode layer. The first insulating part divides the first electrode layer into a first electrode and a second electrode which are independent from each other; the second insulating part is attached to the first insulating part and the first electrode layer, and the orthographic projection, facing the first insulating part, of the second insulating part covers the first insulating part. According to the utility model, the technical problems that the ind
