Description

Contact pressing fixture Technical Field

[0001] This utility model relates to the field of tooling fixtures, specifically to a contact pressing fixture. Background Technology

[0002] Contacts are components of circuit breakers, including moving contacts and stationary contacts. The contact shown in Figure 1 is a moving contact, which mainly includes a busbar 12 and a contact seat 11. The busbar 12 and the contact seat 11 are connected by two pairs of side plates 13. The side plates 13 are connected to the contact seat 11 by two first pins 14, and the side plates 13 are connected to the busbar 12 by a second pin 15. Multiple springs are installed on the contact seat 11. When the busbar 12 and the contact seat 11 form a contact, the busbar 12 can rotate relative to the contact seat 11.

[0003] Because there are multiple springs between the busbar 12 and the contact seat, the assembly of the contacts is quite difficult and requires the assistance of special tooling. The previous tooling fixtures were based on a simple principle, which resulted in slow clamping, inconvenient changeover, high requirements for workers' assembly skills, high workload for operators, and the need for full-time on-site operation. The fixtures did not have limit fixation and the entire process was manually pressed together, which was inefficient. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a contact pressing fixture to solve the technical problem of low contact assembly efficiency in the past.
