[0042] Working principle:

[0043] Please refer to Figures 1 to 6 , assemble the device as shown in the figure;

[0044] Embodiment 1: The relay protector 1 is directly installed inside the mounting frame 2, and then the relay protector 1 is fixed by rotating the top plate 5, fixing the connecting plate 6 and the adaptor pressure plate 7; in this embodiment, the adaptor pressure plate 7 is made of rubber with good ductility, and the adaptor pressure plate 7 is used to squeeze the relay protector 1, and then the relay protector 1 is fixed inside the mounting frame 2; the installation method of this embodiment is simple and quick, but the installation of the relay protector 1 is not stable enough.

[0045] Embodiment 2: The mounting slide plate 21 is fixed to the back of the relay protector 1 by bolts, and then the mounting slide plate 21 is clamped into the inside of the adapting slide groove 20, and finally the relay protector 1 is fixed by rotating the top plate 5, fixing the connecting plate 6 and the adapting pressure plate 7; in this embodiment, the adapting pressure plate 7 is made of a plate with excellent thermal conductivity, such as a copper alloy plate, an aluminum alloy plate, a thermally conductive ceramic plate, etc., and the adapting pressure plate 7 is attached to the top of the relay protector 1; the installation method of this embodiment is simple, and the installation of the relay protector 1 is sufficiently stable, but the relay protector 1 is connected to the mounting slide plate 21 by bolts, which is relatively troublesome to disassemble and repair.

[0046] Embodiment three: The relay protector 1 is clamped and fixed by two clamping angle seats 25 and the bottom clamping arm 28, and then the mounting slide plate 21 is fixed to the back of the fixed arm plate 22 by bolts, and then the mounting slide plate 21 is clamped into the inside of the adapting slide groove 20, and finally the relay protector 1 is fixed by rotating the top plate 5, fixing the connecting plate 6 and the adapting pressure plate 7; in this embodiment, the adapting pressure plate 7 is the same as the adapting pressure plate 7 of embodiment two; the installation method of this embodiment is more complicated than that of embodiments one and two, but the operation is also very convenient, and the installation stability and disassembly convenience of the relay protector 1 are greatly improved.

[0047] For the above-mentioned embodiments 1 to 3, when disassembling the relay protector 1, first press the two control links 11 to release the restriction of the rotating block 9 on the fixed block 8. Under the elastic force of the spring 2 18, the limit ring 2 19 drives the sliding column 2 17 to slide upward, pushing the connecting arm to deflect upward, and the connecting arm drives the rotating top plate 5 to deflect synchronously, so that the fixed block 8 deviates from the rotating block 9, and then release the control link 11, open the rotating top plate 5, and take the relay protector 1 out from the inside of the installation frame 2, thus completing the disassembly of the relay protector 1; when fixing the relay protector 1, directly engage the fixed block 8 of the rotating top plate 5 with the rotating block 9.
