[0025] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0026] To address the problems existing in the background art, this application proposes the following technical solution: a grounding circuit breaker with a compact internal structure.

[0027] The specific technical solution includes a housing 1 and a clamping assembly 3;

[0028] like Figures 1-4As shown, a through hole 2 is provided on the side wall of the outer casing 1, which facilitates the installation of the wire 9. A clamping assembly 3 is installed on one side of the outer casing 1 and is used to reinforce the wiring. The clamping assembly 3 includes two clamping structures symmetrically installed on both sides of the through hole 2. Each clamping structure includes a fixing box 301 and a pressure plate 302. The fixing box 301 can easily limit the pressure plate 302. The pressure plate 302, which is away from the through hole 2, cannot slide within the fixing box 301. The pressure plate 302 passes through the fixing box 301 between itself and the side wall of the outer casing 1. The pressure plate 302 is away from the fixing box 301. The side wall of 01 is provided with a sliding groove 4, which can facilitate the installation of a gasket 303. The gasket 303 is installed in the sliding groove 4, which can increase the friction between the pressure plate 302 and the wire 9. The two ends of the side wall of the pressure plate 302 on one side are fixedly installed with a pull plate 304 and a limiting plate 305. The pull plate 304 can easily pull the pressure plate 302, and the limiting plate 305 can be inserted into the through hole 2 5 to limit the pressure plate 302 and prevent the pressure plate 302 from sliding out of the fixing box 301. The side wall of the fixing box 301 is provided with a through hole 2 5 that is sleeved on the outside of the limiting plate 305.

[0029] according to Figure 4 As shown, the lower pressure plate 302 is fixed inside the lower fixing box 301. Therefore, the lower pressure plate 302 drives the lower gasket 303 to be fixed below the wire 9 via the lower sliding groove 4. By pressing the pull plate 304 by hand, the pull plate 304 pulls the upper pressure plate 302, allowing the upper pressure plate 302 to move closer to the wire 9 within the upper fixing box 301. Simultaneously, the movement of the upper pressure plate 302 pulls the limiting plate 305, which can then... The through hole 2 5 slides within the through hole 2 5, which can limit the limiting plate 305. The limiting plate 305 can limit the upper pressure plate 302, preventing the upper pressure plate 302 from sliding out of the upper fixing box 301. The movement of the upper pressure plate 302 can drive the upper pad 303 to approach the wire 9 through the upper sliding groove 4. The upper pad 303 can squeeze the wire 9, and the other side of the wire 9 squeezes the lower pad 303, which can fix the wire 9 between the pads 303 on both sides.

[0030] like Figures 1-4 As shown, a fixing component 6 is installed on a fixing box 301 with a through hole 5. The fixing component 6 is used to fix the movable pressure plate 302. The side wall of the pressure plate 302 has multiple slots 7 located between the pull plate 304 and the limiting plate 305. The slots 7 can be connected to the card plate 602. The fixing component 6 includes a limiting box 601 fixedly installed on the fixing box 301 and a card plate 602 passing through the slots 7. The limiting box 601 can limit the card plate 602 and the spring piece 603. The card plate 602 can limit the slot 7 to prevent the slot 7 from moving. The limiting box 601 is equipped with a spring piece 603 fixedly connected to the side wall of the card plate 602. The spring piece 603 can push the card plate 602.

[0031] When the pressure plate 302 moves, it can drive the slot 7 to move. The movement of the slot 7 can squeeze the inclined surface of the plate 602. After the inclined surface of the plate 602 is squeezed, it can drive the plate 602 to move. The plate 602 can move into the limiting box 601 and squeeze the spring 603. The continuous movement of the pressure plate 302 can drive different slots 7 to squeeze the plate 602 in sequence. When the pressure plate 302 can no longer move, the spring 603 can push the pressure plate 302 after being squeezed by the plate 602. At this time, the plate 602 can be pushed and inserted into the slot 7 that is opposite to it. The plate 602 is fixed by the limiting box 601 and can fix the slot 7 connected to it. The fixed slot 7 can fix the pressure plate 302. The pressure plate 302 can drive the pad 303 to be fixed through the sliding groove 4, and can clamp the wire 9 between the two pads 303.

[0032] like Figure 1 and Figure 4 As shown, two card boxes 8 are symmetrically installed on the side wall of the outer shell 1. The card boxes 8 can fix the fixing box 301. Each card box 8 is respectively fitted onto both ends of the fixing box 301 on both sides.

[0033] By pulling the fixing box 301, the fixing box 301 can be pulled out of the card box 8. The movement of the fixing box 301 can drive the pressure plate 302 and the through hole 5 to move. The movement of the pressure plate 302 can drive the pull plate 304, the limiting plate 305 and the slide groove 4 to move. The slide groove 4 can drive the gasket 303 to move, which can facilitate the disassembly of the clamping component 3. By inserting the fixing box 301 into the card box 8, the clamping component 3 can be installed according to the above steps.

[0034] like Figure 1 and Figure 4 As shown, a wire 9 is threaded through the through hole 2, which allows the circuit breaker to be energized easily.

[0035] like Figure 1 As shown, a screw 10 is provided on the side wall of the outer casing 1, which is movably connected to the wire 9. The screw 10 can easily fix the wire 9 in the through hole 2.

[0036] like Figure 1 As shown, a switch 11 is installed on the housing 1. The switch 11 can be used to control the circuit breaker's open and closed states.

[0037] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
