Abstract

The invention relates to a tool which is used for dismounting a plum blossom contact for switching in a high voltage electrical product, comprising a retaining base, top plates and an adjusting rod; the retaining base is provided with a centre hole, the adjusting rod penetrates through the centre hole and is extended out of the retaining base and is movably arranged with the retaining base, a plurality of the top plates are circumferentially and movably arranged on the end surface of the retaining base by taking the adjusting rod as the axle to form a top plate group, an elastic reset device is circumferentially arranged on the top plate group, an inclined surface is arranged at one side of top plate, which is toward to the axle, the inclined surfaces on a plurality of top plates which form the top plate group circumferentially form a cone-shaped adjusting cavity, the end part of the adjusting rod is arranged in the cone-shaped adjusting cavity, and the diameter of the end part of the adjusting rod is more than the diameter of the top part of the cone-shaped adjusting cavity. The tool has the advantages that: the plum blossom contact is dismounted conveniently and quickly, the plum blossom contact can be effectively protected from not being damaged, the passing percent of the product is increased, the manufacturing efficiency is increased and the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to a frock for disassembling and assembling a plum blossom contact of a switch in a high-voltage electric appliance product. Background technique [0002] As we all know, in high-voltage electrical products, the plum blossom contact is famous for its product performance, product capacity and reliability, such as figure 1 As mentioned above, the plum blossom contact uses the contact spring to clamp the main current-carrying contact finger on the conductor. This structure is compact and reliable, but it is inconvenient to disassemble and assemble. Generally, two methods are used for disassembly and assembly: the first is to use Special pliers are used to disassemble and assemble. The end of the contact finger 13 of the plum blossom contact is clamped by the special pliers, so that when the diameter of the tail of the plum blossom contact is larger than the diameter of the step of the conductor 14, the plum blossom contact is taken o...
