[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-6 A plug-in capacitor includes a mounting base 1, a plurality of support columns 102 are fixedly connected inside the mounting base 1, a cover plate 3 is fixedly connected inside the mounting base 1 through the cooperation of the support columns 102 and bolts, a capacitor slot is provided inside the cover plate 3 and the mounting base 1, a capacitor assembly is movably plugged inside the capacitor slot, and a plug-in assembly for fixing the capacitor assembly is provided below the cover plate 3;

[0025] The plug-in assembly includes four groups of semi-annular fixing parts 4, which cooperate with each other to clamp and fix the capacitor assembly. The two groups of fixing parts 4 on the same side are fixedly connected by the cooperation of the connecting rod 401. The outer end surface of the connecting rod 401 is fixedly connected with a pull rod 5 extending to the outside of the mounting seat 1. The capacitor assembly is fixed by the plug-in assembly to prevent the capacitor assembly from falling off. At the same time, the capacitor assembly is inserted into the mounting seat 1 and fixed, which facilitates the insertion and removal of the capacitor assembly.

[0026] One inner end of the pull rod 5 is fixedly connected to the connecting piece 502, and the connecting piece 502 is fixedly connected to the connecting rod 401 by means of bolts, which facilitates the assembly and disassembly of the device.

[0027] One outer end of the pull rod 5 is fixedly connected with a pull plate 501 by means of bolts. The pull plate 501 can be provided to facilitate the movement of the pull rod 5.

[0028] An elastic member 6 is sleeved on the outer end surface of the pull rod 5 . The pull rod 5 moves inwardly through the cooperation of the elastic member 6 , and can abut against the fixing member 4 to reset under the action of the elastic member 6 .

[0029] The mounting base 1 is internally fixedly connected to a limiting block 101, and the inner end face of the connecting rod 401 is fixedly connected to an abutting rod 7 that penetrates the limiting block 101. The outer end of the abutting rod 7 movably abuts against another set of connecting rods 401. Through the cooperation of the abutting rod 7 and the limiting block 101, the movement of the fixing part 4 can be limited, the capacitor assembly will not be excessively squeezed, and at the same time, the fixing part 4 can be prevented from being misplaced, thereby ensuring the stable operation of the device.

[0030] The capacitor assembly includes a capacitor body 2 that is movably plugged into the inside of the mounting base 1, and two groups of plug pins 201 are fixedly connected to the lower end surface of the capacitor body 2. The plug pins 201 are movably plugged into the inside of the capacitor slot. When the plug pins 201 are inserted into the capacitor slot, the plug pins 201 can be locked and fixed by the fixing member 4 so that they cannot be pulled out.

[0031] A supporting edge 103 for supporting the cover plate 3 is fixedly connected to the interior of the mounting seat 1. Through the cooperation of the supporting edge 103, the cover plate 3 can be well supported to ensure the stability of the device.

[0032] Working method: When working, by pulling the pull plate 501 outward, the pull rod 5 and the connecting rod 401 are driven, and cooperate with each other to drive the fixing part 4 on the same side to move outward, so that the spacing between the opposite fixing parts 4 is expanded, and the plug pin 201 can be inserted. After the plug pin 201 of the capacitor body 2 is inserted into the capacitor slot, the pull plate 501 can be released, and under the action of the elastic part 6, it can abut against the fixing part 4 to reset. At this time, the fixing part 4 engages and fixes the plug pin 201, so that the capacitor body 2 cannot be pulled out. The device is simple to assemble, can well fix the capacitor body 2 to prevent loosening, and has good safety and stability.
