[0002] The circuit breaker refers to a switch device capable of closing, carrying and opening the current under normal circuit conditions and capable of closing, carrying and opening the current under abnormal circuit conditions within a specified time.

[0003] The circuit breaker can be used to distribute electric energy, start the asynchronous motor infrequently, and protect the power supply line and motor, etc. when serious overloads or short circuits and under-voltage faults occur, it can automatically cut off the circuit, and its function is equivalent to the combination of the fuse-type switch and the over-voltage and under-voltage relay. Moreover, it generally does not need to change parts after breaking the fault current. At present, it has been widely used.

[0004] At present, the wiring terminal of the circuit breaker on the market is fixed by using a screw. This way needs to be used with a screwdriver, and most of the wiring places are narrow in space, which is very inconvenient to use and troublesome to operate. Moreover, when the screw extrudes the wire, the wire may be extruded to one side, and the screw does not press the wire, which causes the wire to be not fixed firmly, and causes the wire to be easily disconnected to cause power failure, and even causes short circuit due to poor contact, and damages the line and the circuit breaker. SUMMARY

[0005] In view of the problems in the prior art, the present application provides a grounding circuit breaker.

[0007] The present application has the following beneficial effects:

[0008] (1) The use of the box body structure can not only limit the sliding of the fixing piece, but also make the clamping piece tighten, so as to clamp the wire and avoid the wire from falling off and skewing.

[0009] (2) The use of the fixing piece replaces the original screw fixing mode of the wire, simplifies the operation steps, makes the wire fixing more quick and convenient, and effectively prevents the wire from sliding left and right, avoids causing unstable installation of the wire, and causes problems such as disconnection and poor contact.

DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, purposes and effects of the application easy to understand, the application will be further described below in combination with specific embodiments.

[0016] As Figures 1-5As shown, the grounding circuit breaker comprises a box structure 1, a fixing member 2 and a clamping member 3; the box structure 1 and the fixing member 2 are in sliding connection for limiting the position of the fixing member 2 and making the clamping member 3 clamped; the fixing member 2 is in contact with the inside of the box structure 1 for fixing the wire and pushing the clamping member 3 to slide; the clamping member 3 is in sliding connection with the box structure 1 for clamping and avoiding the wire from running around; the use of the box structure 1 can not only limit the sliding of the fixing member 2, but also make the clamping member 3 tighten, so as to clamp the wire and avoid the wire from falling off and skewing; the use of the fixing member 2 instead of the original screw fixing mode of the wire simplifies the operation steps and makes the wire fixing more convenient and fast, and effectively prevents the wire from sliding left and right, avoids causing unstable installation of the wire, causes the problems of disconnection and poor contact and the like; the use of the clamping member 3 can not only clamp the wire, improve the stability of the fixing member 2 in fixing the wire and prevent the wire from disconnection, but also wrap the wire, so that the wire cannot run around left and right, makes the fixing member 2 accurately clamp the wire and improves the reliability of the fixing member 2; the mutual cooperation of the box structure 1, the fixing member 2 and the clamping member 3 improves the wire fixing speed, simplifies the installation steps of the wire and makes the circuit breaker wiring more convenient and fast, and at the same time, ensures that the wire will not skew, avoids the problems of poor contact between the wire and the conductive structure and disconnection caused by the loosening of the wire and the like.

[0017] It should be noted that the box structure 1 includes a box body 11, a slot 12, a switch 13, a tensioning groove 14, a first biting tooth 15, a first limiting tooth 16, a sliding groove 17, a spring 18, a release tooth 19, and a second spring 19a. The fixing member 2 is slidably connected to the box body 11. The slot 12 is located on the back of the box body 11, the switch 13 is located on the front of the box body 11, and the tensioning groove 14, which has different sizes at both ends, is located at the top and bottom of the box body 11. At the bottom, the first biting tooth 15 is disposed inside both ends of the box body 11, and the first biting tooth 15 is electrically connected to the internal circuit of the box body 11. The first limiting tooth 16 is fixed inside both ends of the box body 11. The sliding groove 17 is disposed inside the box body 11. The spring 18 is fixed inside the sliding groove 17. The release tooth 19 is slidably connected inside the sliding groove 17, and one end of the spring 18 is fixed to the release tooth 19. On the side wall, one end of the second spring 19a abuts against the interior of the housing 11; the wire is passed through the clamping member 3 in the tensioning groove 14 into the interior of the housing 11, and then the button 21 is pressed, causing the fixing member 2 to move the wire closer to the first biting tooth 15, the second spring 19a is compressed, and the fixing member 2 and the first biting tooth 15 cooperate to fix the wire; during the process of the fixing member 2 pressing the wire, the second limiting tooth 25 and the first limiting tooth 16 engage and connect, so that the fixing member 2 can firmly press the wire; when removing the wire, the button 21 is pressed again, the fixing member 2 continues to enter the interior of the housing 11, the second spring 19a continues to be compressed, the fixing member 2 abuts against and passes the release tooth 19, and then the fixing member 2 is released, the fixing member 2 rebounds, moving the release tooth 19 closer to the first limiting tooth 16, and the release tooth 19 slides to the right side of the slide groove 17 (according to the appendix). Figure 3 (The direction is the same below), and squeeze the spring 18. When the release tooth 19 abuts against the first limiting tooth 16, the fixing member 2 will easily pass over the first limiting tooth 16. The release tooth 19 loses the abutment of the fixing member 2 and slides to the left end of the slide groove 17 under the action of the spring 18 until the release tooth 19 is reset, the fixing member separates from the first biting tooth 15, and the wire is loosened.

[0018] Furthermore, the fixing component 2 includes a button 21, a slide cylinder 22, a torsion spring 23, a third spring 24, a second limiting tooth 25, a limiting block 26, a fourth spring 27, a sliding column 28, a limiting strip 29, a second biting tooth 29a, a pushing groove 29b, and an anti-loosening texture 29c. The slide cylinder 22 is slidably connected to the inside of the housing 11, and the other end of the second spring 19a is fixed to the side wall of the slide cylinder 22. The button 21 is slidably connected to the inside of the slide cylinder 22, and the button 21 and the slide cylinder 22 are... The torsion spring 23 is sleeved on the outer wall of the button 21, and one end of the torsion spring 23 is fixed to the inner wall of the slide cylinder 22. The spring 24 is installed inside the slide cylinder 22. The second limiting tooth 25 is slidably connected to the inside of the slide cylinder 22, and one end of the spring 24 is fixed to the bottom surface of the second limiting tooth 25. The top end of the second limiting tooth 25 abuts against the first limiting tooth 16 and the release tooth 19. The two limiting blocks 26 are symmetrically fixed to the button 21. The bottom outer wall of button 21 has one end of spring 27 fixed to the bottom end of button 21, the interior of sliding post 28 slidably connected to the outer wall of button 21, and the other end of spring 27 fixed to the interior of sliding post 28. Two limiting strips 29 are spaced apart at the top of sliding post 28, and the two limiting strips 29 abut against limiting block 26. The second bit 29a is fixed to the bottom end of sliding post 28, and the second bit 29a abuts against the first bit 15. The push groove 29b is symmetrically arranged on the side wall of the sliding column 28, and the limiting block 26 is slidably connected to the push groove 29b. The anti-slip texture 29c is provided on the surface of the first bite tooth 15 and the second bite tooth 29a. When the second bite tooth 29a does not abut against the first bite tooth 15, the bottom surface of the limiting block 26 at the bottom end of the button 21 always abuts against the top surface of the sliding column 28, and under the action of the torsion spring 23, the side wall of the limiting block 26 always abuts against one end of the limiting strip 29.When button 21 is pressed, button 21 drives the slide cylinder 22 to slide into the housing 11. The slide cylinder 22 causes the second limiting tooth 25 to abut against the first limiting tooth 16. The second limiting tooth 25 slides into the slide cylinder 22 and compresses the spring 3 24. The second limiting tooth 25 slides into the slide cylinder 22, causing the second limiting tooth 25 to pass over the first limiting tooth 16. After that, the first limiting tooth 16 no longer abuts against the second limiting tooth 25, and the second limiting tooth 25 is pushed out by the spring 3 24. The sidewall of the first limiting tooth 16 abuts against the sidewall of the second limiting tooth 25, preventing the slide cylinder 22 from retracting. Simultaneously, the limiting block 26 pushes the sliding column 28 to slide together. The sliding column 28 drives the second bit 29a to approach the first bit 15, clamping the wire between the first bit 15 and the second bit 29a. The first bit 15 and the second bit 29a bite each other, so that the wire fits the first bit 15 and the second bit 29a. Moreover, with the inverted triangular anti-detachment texture 29c, the wire is less likely to fall off and fits more tightly with the first bit 15, making the conductivity more stable. During the movement of the second bit 29a, it will also drive the clamping member 3 to move, so that the clamping member 3 gradually clamps the wire.When removing the wire, first turn the button 21. The button causes the limiting block 26 to rotate, compressing the torsion spring 23. When the side wall of the limiting block 26 abuts against the other end of the other limiting strip 29, press the button 21. The button 21 causes the limiting block 26 to enter the pushing groove 29b and continue to slide within it, compressing the spring 27. As the button 21 continues to slide into the housing 11, the slide cylinder 22 moves along with the button 21, driving the second limiting... As tooth 25 moves, the second limiting tooth 25 abuts against the release tooth 19, and the release tooth 19 slides into the slide cylinder 22. The spring 3 24 is compressed, and then the second limiting tooth 25 passes over the release tooth 19. The spring 3 24 pushes out the second limiting tooth 25, causing the side wall of the second limiting tooth 25 to engage with the release tooth 19. After releasing the button 21, the spring 2 19a pushes the slide cylinder 22, the button 21, and the second biting tooth 29a back, causing the second limiting tooth 25 to move the release tooth 19 closer to the button 22. When the first limiting tooth 16 approaches, the spring 18 is compressed. When the release tooth 19 abuts against the first limiting tooth 16, the second limiting tooth 25 is pressed into the slide cylinder 22 by the release tooth 19, and the spring 24 is compressed. The second limiting tooth 25 passes over the release tooth 19 and the first limiting tooth 16. The release tooth 19 loses the contact of the second limiting tooth 25 and slides towards the left end of the slide groove 17 under the action of the spring 18 until the release tooth 19 returns to its original position. The second limiting tooth 25 is then pressed into the slide cylinder 22 by the spring 24. Pushed by 4, the button 21 slides out of the slide cylinder 22, and the second bit 29a separates from the first bit 15, loosening the wire. Simultaneously, pushed by the spring 27, the limiting block 26 at the bottom of the button 21 slides out of the pushing groove 29b. When the limiting block 26 slides out of the pushing groove 29b, under the action of the torsion spring 23, the button 21 immediately rotates until the side wall of the limiting block 26 again abuts against the side wall of the limiting strip 29. During the return of the second bit 25, the clamping member 3 will slide.

[0019] In this invention, the clamping member 3 includes a clamping plate 31, an anti-slip strip 32, a slider 33, and a second sliding groove 34. Two arc-shaped clamping plates 31 are slidably connected to the inside of the tension groove 14. The anti-slip strip 32 is located on the front of the clamping plate 31. The slider 33 is fixed to the back of the clamping plate 31 and to the side wall of the second bite tooth 29a. The second sliding groove 34 is located on the side wall of the tension groove 14, and the slider 33 is slidably connected to the inside of the second sliding groove 34. When the fixing member 2 slides into the box body 11, it pushes the slider 33 to slide within the second sliding groove 34. The slider 33 drives the clamping plate 31 to slide. Since one end of the tension groove 14 is larger than the other end... When the fixing member 2 enters the box 11, the clamping plate 31 slides from the larger end of the tension groove 14 to the smaller end, so the clamping plate 31 gradually tightens and wraps around the wire. The anti-slip strip 32 tightly abuts against the wire, which not only makes it difficult for the wire to fall off, but also prevents the wire from swinging back and forth. When the fixing member 2 slides out of the box 11, it also drives the slider 33 to slide in the second slide groove 34, so that the clamping plate 31 slides from the smaller end of the tension groove 14 to the larger end. During this process, the clamping plate 31 can still fix the wire and prevent the wire from swinging wildly. The clamping plate 31 gradually loosens, and finally, the wire can be easily taken out from the clamping plate 31.

[0020] The wire is passed through the clamp 31 in the elastic groove 14 into the interior of the housing 11. Then, the button 21 is pressed, which drives the slide cylinder 22 to slide into the housing 11. The slide cylinder 22 causes the second limiting tooth 25 to abut against the first limiting tooth 16. The second limiting tooth 25 slides into the slide cylinder 22 and compresses the spring 34. The second limiting tooth 25 slides into the slide cylinder 22, so that the second limiting tooth 25 passes over the first limiting tooth 16. After that, the first limiting tooth 16 no longer abuts against the second limiting tooth 25. The second limiting tooth 25 is pushed out by the spring 34. The sidewall of the first limiting tooth 16 abuts against the sidewall of the second limiting tooth 25, making the slide cylinder 22 unable to retract. At the same time, the limiting block 26 pushes the sliding column 28 to slide together. The sliding column 28 drives the second biting tooth 29a to approach the first... A tooth 15 clamps the wire between the first tooth 15 and the second tooth 29a, and the first tooth 15 and the second tooth 29a interlock, so that the wire fits the first tooth 15 and the second tooth 29a. It also fits with the triangular anti-detachment texture 29c, making the wire less likely to fall off and fits more tightly with the first tooth 15, making the conductivity more stable. During the movement of the second tooth 29a, it will also drive the slider 33 to slide in the second groove 34. The slider 33 drives the clamping plate 31 to slide. Since the tension groove 14 is larger at one end and smaller at the other end, when the fixing member 2 enters the box 11, the clamping plate 31 slides from the larger end of the tension groove 14 to the smaller end. Therefore, the clamping plate 31 gradually tightens and wraps the wire. The anti-slip strip 32 tightly abuts against the wire, which not only makes the wire less likely to fall off, but also prevents the wire from shaking back and forth.When removing the wire, first turn the button 21. The button causes the limiting block 26 to rotate, compressing the torsion spring 23. When the side wall of the limiting block 26 abuts against the other end of the other limiting strip 29, press the button 21. The button 21 causes the limiting block 26 to enter the pushing groove 29b and continue to slide within it, compressing the spring 27. As the button 21 continues to slide into the housing 11, the slide cylinder 22 moves along with the button 21. The slide cylinder 22 causes the second limiting tooth 25 to move, and the second limiting tooth 25 abuts against the release tooth 19. The release tooth 19 slides into the slide cylinder 22, the spring 24 is compressed, and then the second limiting tooth 25 passes over the release tooth 19. The spring 24 pushes out the second limiting tooth 25, so that the side wall of the second limiting tooth 25 engages with the release tooth 19. Then the button 21 is released, the spring 29a pushes the slide cylinder 22, the button 21, and the second biting tooth 29a to rebound, so that the second limiting tooth 25 drives the release tooth 19 closer to the first limiting tooth 16, the spring 18 is compressed, and when the release tooth 19 abuts against the first limiting tooth 16, the second limiting tooth... The tooth 25 is pressed into the slide cylinder 22 by the release tooth 19, the spring 3 24 is compressed, the second limiting tooth 25 passes over the release tooth 19 and the first limiting tooth 16, the release tooth 19 loses the contact of the second limiting tooth 25, and slides to the left end of the slide groove 17 under the action of the spring 18 until the release tooth 19 is reset, the second limiting tooth 25 slides out of the slide cylinder 22 under the push of the spring 3 24, and the second biting tooth 29a separates from the first biting tooth 15, the wire is loosened, and at the same time, under the push of the spring 4 27, the limiting block at the bottom of the button 21 is released. 26 slides out of the pushing groove 29b. When the limiting block 26 slides out of the pushing groove 29b, under the action of the torsion spring 23, the button 21 immediately rotates until the side wall of the limiting block 26 abuts against the side wall of the limiting strip 29 again. During the process of the second biting tooth 25 springing back, it also drives the slider 33 to slide in the second sliding groove 34, so that the clamping plate 31 slides from the smaller end of the tensioning groove 14 to the larger end. During this process, the clamping plate 31 can still fix the wire and prevent the wire from swinging wildly. The clamping plate 31 gradually loosens, and finally, the wire can be easily removed from the clamping plate 31.
