description The utility model relates to a self-positioning pipe shell, belongs to the technical field of semiconductor device pipe shells and mainly aims to solve the problems that the existing thyristor or diode encapsulated in the pipe shell is difficult to position, is complex in structure and is slightly thick. The self-positioning pipe shell is mainly characterized by comprising an upper encapsulating component and a lower encapsulating component, wherein the upper encapsulating component comprises a cathode copper block and a cathode oxygen-free copper sheet; and the lower encapsulating component comprises a copper block, a porcelain piece and an oxygen-free copper sheet, wherein the outer circumference of the copper block is provided with a convex ring, a groove for fixing a pipe core is formed in the convex ring, and the center of the copper block is provided with an outward convex base. The self-positioning pipe shell provided by the utility model has the characteristics that the thyristor or diode core can be
