To sum up, the embodiment of the present invention provides a pair of rotation type anti-disengaging structure 100 and electric cabinet, has the following several beneficial effects:

this rotation type anti-disengaging structure 100 sets up reinforcement 210 on transitional coupling platform 20, and reinforcement 210 has the portion of bending 213 and the portion of inserting 211 that form the angle of predetermineeing, and reinforcement 210 can rotate in spliced eye 310 after inserting the spliced eye 310 of PCB board 30 to make portion of bending 213 and PCB board 30 joint, and will bend 213 and PCB board 30 welding, form stable connection structure, prevent that vibration in-process transitional coupling platform 20 and PCB board 30 from separating. The length of the insertion portion 211 is smaller than the thickness of the PCB 30, so that the clamping force of the bending portion 213 and the PCB 30 is larger, the structure is more stable, the transitional connection platform 20 is tightly attached to the PCB 30, the reduction of line resistance is facilitated, and the heat loss of electric energy is reduced. OT link 10 fastens to the surface of transitional coupling platform 20 through the bolt, and stable in structure is reliable, also is favorable to reducing the circuit resistance.

This electric cabinet includes foretell rotation type anti-disengaging structure 100, is adapted to the operational environment of heavy current, strong vibration, connects reliably, stable in structure, and the anticreep is effectual, can ensure that the circuit is unobstructed, and equipment reliability is high, long service life.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
