Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit breaker technology, specifically to a circuit breaker that is easy to wire. Background Technology
[0002] In modern power systems, circuit breakers, as the core components of circuit protection, play an important role in controlling and protecting circuits. Their performance directly affects the safe and stable operation of the power system. In the wiring process of traditional circuit breakers, wires are usually connected by screw fastening or clamping with pressure plates. However, this wiring method has many limitations.
[0003] When wiring existing circuit breakers, wires are usually fixed in the wiring holes of the circuit breaker with screws. Tightening the screws requires repeated tightening with screwdrivers and other tools, which is a cumbersome and time-consuming process.
[0004] According to the description in the patent announcement (authorization announcement number: CN216145574U) of a circuit breaker that is easy to wire, the circuit breaker includes a "body, wiring frame" etc. to realize the wiring work.
[0005] Regarding the above description, the applicant believes the following issues exist:
[0006] This circuit breaker, designed for easy wiring, utilizes its body and wiring frame for wiring operations. During operation, the main gear rotates, driving the central front connecting plate to rotate, which in turn drives the driven gear to rotate. The driven gears then drive the front connecting plates on both sides to rotate. When the main gear drives the driven gears, the left and right driven gears rotate in opposite directions. When the rear connecting plate rotates, driving the transmission screws to rotate, the left and right transmission screws rotate in opposite directions, preventing the extruded copper plates from moving in the same direction and causing jamming. Therefore, this circuit breaker needs improvement. Utility Model Content

[0009] The wiring mechanism includes a circuit breaker body, which is slidably connected to the periphery of a mounting plate. A support frame is fixedly connected to the top of the front surface of the circuit breaker body. A first adjusting shaft is rotatably connected inside the support frame. A movable frame is threadedly connected to the periphery of the first adjusting shaft. A connecting rod is fixedly connected to the rear side of the movable frame. An extruded copper sheet is fixedly connected to the rear side of the connecting rod. A fixed frame is fixedly connected to the top of the circuit breaker body.

[0010] Preferably, the rear side of the first adjusting shaft is rotatably connected to the top of the front surface of the circuit breaker body, the movable frame is slidably connected to the inner side of the support frame, and the connecting rod and the extruded copper sheet are slidably connected to the inside of the circuit breaker body, so as to fix the cable connected to the circuit breaker body by extruding the copper sheet.
[0011] Preferably, there are three sets of connecting rods and extruded copper sheets, which are symmetrically distributed on the rear side of the movable frame to facilitate the simultaneous fixing of multiple sets of cables.
[0012] Preferably, the bottom of the protective cover is in contact with the top of the circuit breaker body, and an insulating pad is provided on the inner side of the clamping block to facilitate the protection of the wiring positions on the upper and lower sides of the circuit breaker body through the protective cover.
[0013] Preferably, the support frame, fixing frame, first adjusting shaft, moving frame, connecting rod, extruded copper sheet, rotating rod, protective cover, second adjusting shaft, rectangular plate and clamping block are provided in two sets and symmetrically distributed on the upper and lower sides of the circuit breaker body.

[0016] Compared with the prior art, this utility model provides a circuit breaker that is easy to wire and has the following features:
[0017] Beneficial effects:
[0018] 1. This easy-to-wire circuit breaker, through its wiring mechanism, allows for easy connection during use. First, the cables to be connected to the circuit breaker body are inserted into the top of the circuit breaker body. Rotating the first adjusting shaft drives the moving frame to slide along the support frame, moving the connecting rod and the pressing copper plate. This allows the pressing copper plate to contact and press the cables. The rectangular bottom of the pressing copper plate ensures the stability of the cables inside the circuit breaker body, accurately and quickly pressing and fixing the wires inside the circuit breaker body without the need for complex manual winding or screw tightening operations. This significantly shortens wiring time. Three sets of symmetrically distributed connecting rods and extruding copper sheets can simultaneously and stably extrude and fix multiple wires, meeting various wiring requirements. When the fixing is complete, the cable is bent backward at the top of the circuit breaker body. At this time, the protective cover is outside the rotating rod and slidably connected to the outside of the cable, protecting the top of the circuit breaker body. When the second adjusting shaft is rotated, the rectangular plate slides along the inside of the protective cover, causing the clamping block to descend and clamp the wire. The insulating pad inside the clamping block not only increases the friction with the wire to prevent the wire from loosening, but also plays an insulating protection role, avoiding the risk of leakage.
[0019] 2. This circuit breaker, which is easy to wire, has a fixed mechanism in place. The connecting block is connected to the rotating rod. By inserting the first plug into the connecting block, the second plug on the fixed plate is inserted into the fixed frame. The fixed frame is connected to the fixed shaft by thread. This ensures the stability of the protective cover when it is on the upper and lower sides of the circuit breaker body and is outside the cable for protection. When wiring is required, simply unscrew the fixed shaft and pull out the first and second plugs for easy operation. Attached Figure Description

[0031] This utility model provides the following technical solution:
[0032] Example 1
[0033] Please see Figure 1-7 This utility model provides a technical solution: a circuit breaker that is easy to wire, including a mounting plate 1, a wiring mechanism 2 is provided on the front side of the mounting plate 1, and a fixing mechanism 3 is provided on the right side of the wiring mechanism 2;
[0034] The wiring mechanism 2 includes a circuit breaker body 21, which is slidably connected to the periphery of the mounting plate 1. A support frame 22 is fixedly connected to the top of the front surface of the circuit breaker body 21. A first adjusting shaft 24 is rotatably connected inside the support frame 22. A movable frame 25 is threadedly connected to the periphery of the first adjusting shaft 24. A connecting rod 26 is fixedly connected to the rear side of the movable frame 25. An extruded copper sheet 27 is fixedly connected to the rear side of the connecting rod 26. A fixed frame 23 is fixedly connected to the top of the circuit breaker body 21. A rotating rod 28 is rotatably connected inside the fixed frame 23. A protective cover 29 is fixedly connected to the periphery of the rotating rod 28. A second adjusting shaft 291 is threadedly connected inside the protective cover 29. A rectangular plate 292 is rotatably connected to the periphery of the bottom of the second adjusting shaft 291. The rectangular plate 292 is slidably connected to the inner side of the protective cover 29. A clamping block 293 is fixedly connected to the bottom of the rectangular plate 292.
[0035] The first adjusting shaft 24 is rotatably connected to the top of the front surface of the circuit breaker body 21. The moving frame 25 is slidably connected to the inside of the support frame 22. The connecting rod 26 and the extruded copper sheet 27 are slidably connected to the inside of the circuit breaker body 21, so that the cables connected to the circuit breaker body 21 can be fixed by extruding the copper sheet 27.
[0036] There are three sets of connecting rods 26 and extruded copper sheets 27, which are symmetrically distributed on the rear side of the movable frame 25, so as to facilitate the simultaneous fixing of multiple sets of cables.
[0037] The bottom of the protective cover 29 is in contact with the top of the circuit breaker body 21. An insulating pad is provided on the inner side of the clamping block 293 to facilitate the protection of the wiring positions on the upper and lower sides of the circuit breaker body 21 through the protective cover 29. The support frame 22, the fixing frame 23, the first adjusting shaft 24, the moving frame 25, the connecting rod 26, the extruded copper sheet 27, the rotating rod 28, the protective cover 29, the second adjusting shaft 291, the rectangular plate 292 and the clamping block 293 are provided in two sets and are symmetrically distributed on the upper and lower sides of the circuit breaker body 21. By setting two sets, the convenience of connecting the incoming and outgoing lines of the circuit breaker body 21 can be further improved.
[0038] Example 2
[0039] Please see Figure 1-7 Furthermore, based on Embodiment 1, the fixing mechanism 3 further includes a connecting block 31, which is fixedly connected to the right side of the rotating rod 28. A first insert block 32 is inserted inside the connecting block 31. A fixing plate 33 is fixedly connected to the front side of the first insert block 32. A second insert block 35 is fixedly connected to the rear side of the fixing plate 33. A fixing shaft 34 is threaded inside the fixing plate 33.
[0040] The second insert 35 is inserted into the inside of the fixing frame 23, and the rear side of the fixing shaft 34 is threaded into the inside of the fixing frame 23, so as to ensure the stability of the fixing plate 33 through the fixing shaft 34.
[0041] In actual operation, when this device is in use, when the circuit breaker body 21 needs to be wired, firstly, the cables that need to be connected to the circuit breaker body 21 are inserted into the top of the circuit breaker body 21. Rotating the first adjusting shaft 24 can drive the moving frame 25 to slide along the support frame 22, which drives the connecting rod 26 and the pressing copper sheet 27 to move, so that the pressing copper sheet 27 contacts the cable and presses it. The bottom of the pressing copper sheet 27 is rectangular, which can ensure the stability of the cable inside the circuit breaker body 21. It can accurately and quickly press and fix the wire inside the circuit breaker body 21 without complicated manual winding or screw tightening operations, which greatly shortens the wiring time. The three sets of symmetrically distributed connecting rods 26 and pressing copper sheets 27 can simultaneously press and fix multiple wires stably, meeting various wiring needs.
[0042] When the fixing is completed, the cable is bent backward at the top of the circuit breaker body 21. At this time, the protective cover 29 rotates around the rotating rod 28 and slides to the outside of the cable to protect the top of the circuit breaker body 21. When the second adjusting shaft 291 is rotated, the rectangular plate 292 slides along the inside of the protective cover 29, which drives the clamp 293 to descend and clamp the wire. The insulating pad on the inside of the clamp 293 can not only increase the friction with the wire to prevent the wire from loosening, but also play an insulating protection role to avoid the risk of leakage. The two sets of symmetrically distributed support frames 22, clamps 293 and other components can fix the wire from the top and bottom sides, further enhancing the stability of the wire fixing and ensuring that the circuit connection is firm.
[0043] After the protection is completed, insert the first plug 32 into the connecting block 31, so that the second plug 35 on the fixing plate 33 is inserted into the fixing frame 23, and use the fixing shaft 34 to thread the fixing frame 23. This can ensure the stability of the protective cover 29 when it is on the upper and lower sides of the circuit breaker body 21 and is located outside the cable for protection. When wiring is required, simply unscrew the fixing shaft 34 and pull out the first plug 32 and the second plug 35 for easy operation. After the wiring and fixing are completed, the circuit breaker body 21 can be fixed on the mounting plate 1 by external fixing equipment, and the mounting plate 1 can be fixed in the position where the circuit breaker body 21 is used by external fixing equipment.
[0044] The wiring steps and methods at the bottom of the circuit breaker body 21 are the same as those at the top;
[0045] The circuit breaker body 21 is existing technology. Those skilled in the art are well aware of the specific operating steps and usage methods of this device. This case will not describe the usage methods in detail.
