Abstract
The invention discloses a rolled reinforced seal type binding post for a power capacitor. The rolled reinforced seal type binding post for the power capacitor comprises a wiring assembly, a porcelain insulator and an installation assembly. An annular locating boss protruding in the radial direction is arranged on the outer wall of the lower portion of the insulator. The installation assembly comprises a metal base, an annular seal ring and a base tube, wherein the annular seal ring is arranged on the outer wall of the lower portion of the insulator in a sleeved mode and is adjacent to the bottom wall of the annular locating boss. The metal base comprises a compression connection portion, a sleeved connection portion and a rolled ring, wherein the rolled ring is formed in the mode that the top end of the sleeved connection portion of the base is rolled inwards. The base tube comprises a welding portion and a sleeve portion. The welding portion of the base tube is fixedly welded to and connected with the compression connection portion of the metal base. The wiring assembly comprises a sealing gasket, a bolt and a rolled connecting piece. The bottom end of the rolled portion of the rolled connecting piece is rolled to deform and protrudes inwards, so that a rolled buckle ring is formed. The rolled reinforced seal type binding post for the power capacitor is compact and reasonable in structure and capable of effectively preventing the phenomenon that the metal base slides in the circumferential direction of the insulator, and therefore the sealing performance of the rolled reinforced seal type binding post is guaranteed.
