Assembling jig of conductive elastic sheet

The utility model provides an assembling jig for a conductive elastic sheet. The assembling jig comprises a jig body, wherein the cross section size of the jig body is smaller than the size of the inner side wall of a cylinder. One end of the jig body is used for abutting against the circular ring piece, and the jig body is provided with a limiting part used for limiting the connecting part or the conductive contacts, so that when the negative electrode elastic piece is arranged in the barrel, the barrel or the jig body rotates, the barrel and the negative electrode elastic piece can rotate relatively, the conductive contacts are located in holes in the two sides of the barrel, and the negative electrode elastic piece is clamped in the holes in the two sides of the barrel. The problem that an existing negative electrode elastic piece is inconvenient to align and assemble is solved, and the assembling speed of a vehicle-mounted charger used on an automobile cigarette lighter jack is increased. 本实用新型提供了一种导电弹片的装
