[0002] A frame circuit breaker is a mechanical switching device that can connect, carry, and disconnect current under normal circuit conditions, and can also connect, carry, and disconnect current for a certain time under specified abnormal circuit conditions. It is an important power equipment in the power grid.

[0003] Currently, frame-type circuit breakers have many connected wires, which often leads to misalignment of the wires at the terminals. This can easily cause safety accidents after power is applied and requires rewiring, which is time-consuming and laborious, thus affecting the ease of installation and use of frame-type circuit breakers. To address this, we propose a frame-type circuit breaker designed to prevent installation misalignment. Utility Model Content

Two corresponding connecting holes 24 are opened on the front of the slide plate 23, and a first slot 25 is opened on the upper side of the slide plate 23, communicating with the two connecting holes 24. A connecting component 4 is installed on the rear side of the slide plate 23, connecting to the frame-type circuit breaker 1. The slide plate 23 corresponds to the wiring component 5. Evenly distributed snap-fit ​​components 3 are installed on the front of the support frame 21, corresponding to the slide grooves 22. The snap-fit ​​components 3 include chucks 31, limit plates 32, and a first spring 33. Evenly distributed openings are opened on the front of the support frame 21, and chucks 31 are slidably connected inside the openings. All chucks 31 are located at all... Inside the slide groove 22, the front end of the chuck 31 is fixed with a limiting plate 32. A first spring 33 is sleeved on the circumferential surface of the chuck 31. The front end of the first spring 33 is fixed to the rear end of the limiting plate 32, and the rear end of the first spring 33 is fixed to the front side of the support frame 21. The connecting component 4 includes a connecting groove 41, a slide plate 42, a connecting block 43, a guide port 44, and a second spring 45. The upper side of the frame circuit breaker 1 is provided with evenly distributed connecting grooves 41. The slide plate 42 is slidably connected inside the connecting groove 41. The lower end of the slide plate 42 is fixed with a second spring 45. The second spring 45 is fixed inside the connecting groove 41. The front end of the connecting groove 41 is provided with a guide port 44. The connecting block 43 is slidably connected inside the guide port 44.

[0025] The working principle of the frame-type circuit breaker for preventing installation misalignment provided by this utility model is as follows: First, insert the wires to be connected one by one into all the connection holes 24. At this time, the rubber rings 6 located inside the connection holes will wrap around the wires, thus preventing them from falling off. Then, pull the two wires on the same sliding plate 23 and insert them into the corresponding two wiring holes 52. After insertion, press the sliding plate 23 downwards to make it enter the corresponding slide groove 22. During this process, the two wires on the sliding plate 23 will pass through the two second slots opened in the two rubber rings 6 and the first slot opened on the upper side of the sliding plate 23, separating from the sliding plate 23 and the two rubber rings 6. After the sliding plate 23 enters the corresponding slide groove 22, the chuck 31 corresponding to the slide groove 22 will enter the connection hole 24 on the lower side of the sliding plate 23 under the action of the first spring 33 connected to it, fixing the sliding plate 23. Then, install the remaining wires on the sliding plate 23 one by one. After each pair of wires is installed, the corresponding sliding plate 23 can be inserted into the corresponding slide groove 22. In this way, installation misalignment can be avoided when installing wires.
