The utility model discloses a laminated busbar structure comprising a positive plate equipped with multiple positive threaded holes, a negative plate equipped with multiple negative threaded holes, a top surface insulating film, and a bottom surface insulating film. The positive plate and the negative plate are symmetric in profile. The inner side of the positive plate and the inner side of the negative plate are connected through a bar-shaped insulating strip. The positive threaded holes and the negative threaded holes are in one-to-one correspondence. The top surfaces of the positive plate and the negative plate are connected with the top surface insulating film. The bottom surfaces of the positive plate and the negative plate are connected with the bottom surface insulating film. The laminated busbar structure has characteristics of few material varieties, low material cost, and prevented electrical hidden danger caused by an insulating pad, and can be widely used in the application field of power electronics.
