Description

Technical Field

[0001] The utility model relates to the technical field of industrial loading tools, in particular to an industrial loading tool for a magnetic system. Background Art

[0002] The magnetic system is a component used to be installed in a circuit breaker. When the current transformer detects an abnormal current, it impacts the free tripping module in the circuit breaker to achieve tripping. As Figure 1 shown, the existing magnetic system includes an iron core assembly 100, a coil 200, a static contact 300, a wiring board 400, and a wiring terminal 500. The coil 200 is movably sleeved on the iron core assembly 100. One end of the coil 200 is connected to the static contact 300, and the other end is connected to the wiring board 400. The end of the wiring board 400 is connected to the wiring terminal 500. A threaded hole is provided on the wiring terminal, and a screw 600 is screwed in and tightened from the threaded hole.

[0003] In the prior art, in order to improve work efficiency and accuracy, manual assembly is changed to automatic assembly. Generally, an assembly device is used to assemble the magnetic system. First, the coil 200, the static contact 300, and the wiring board 400 are assembled. Then, the iron core assembly 100 is inserted into the coil 200, and the assembled magnetic component is clamped to an industrial loading tool. Then, the screw 600 is assembled onto the wiring terminal 500. Finally, the wiring terminal 500 is clamped to the industrial loading tool to be assembled with the wiring board 400. However, in the existing assembly devices, usually only one industrial loading tool is provided, and the assembly can only be carried out one by one, resulting in relatively low assembly efficiency. Moreover, during assembly, the stability of the magnetic component is poor, which easily affects the assembly effect. Summary of the Utility Model
