Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker contact riveting, in particular to a riveting die for a circuit breaker contact assembly. Background Art

[0002] In the existing circuit breaker contact assemblies, the contacts are mostly fixed on the elastic pieces by riveting. However, when the elastic pieces are arranged in parallel and the contacts have irregular curved surfaces, as Figure 1-2 shown, the front ends of two adjacent elastic pieces 101 are respectively riveted with contacts 102. The shapes of the contacts 102 on two adjacent elastic pieces 101 are recessed in the adjacent directions. Therefore, when the contacts 102 on two adjacent elastic pieces 101 are riveted synchronously, the two contacts 102 will be extruded and expanded in the opposite directions, thus dispersing the riveting force in the vertical direction, resulting in the phenomenon that the contacts 102 are skewed during riveting, and further affecting the quality of the circuit breaker contact assembly. The existing method is to only rivet the contacts 102 on a single elastic piece separately, and the contacts 102 on the next elastic piece 101 can be riveted only after the contacts 102 on one elastic piece 101 are riveted. However, this greatly affects the riveting efficiency.

[0053] The riveting die for the circuit breaker contact assembly according to an embodiment of the present application is used to simultaneously rivet the contacts 102 to the juxtaposed elastic pieces 101, and the surface of the contact 102 is recessed towards the adjacent contact 102 for the riveting of the circuit breaker contact assembly.

[0054] In an exemplary embodiment, the elastic piece 101 is provided with a through hole at one end, the contact 102 is provided with a contact post 103, the contact 102 passes through the through hole on the elastic piece 101 through the contact post 103, and then the contact post 103 is deformed by squeezing the contact post 103 to realize riveting the contact 102 to the elastic piece 101.

[0075] In an exemplary embodiment, a pressure head 204 is further provided on the upper plate corresponding to the position of the contact 102.

[0076] In an exemplary embodiment, when the upper plate moves in the direction of the base plate 201, the pressure head 204 squeezes the contact post 103 in the vertical direction, and the purpose of riveting the contact 102 is achieved by deforming the contact post 103 protruding from the surface of the elastic piece 101.
