[0002] Miniature circuit breakers play a vital role in modern electrical systems. They must be able to quickly cut off the current when the circuit is overloaded or short-circuited to protect electrical equipment and personal safety. With the advancement of technology, miniature circuit breakers are becoming more and more intelligent and sophisticated, which requires their matching components to also be improved accordingly to adapt to these changes.

[0003] In the process of moving the fork of the circuit breaker, the metal frame is one of the indispensable components, which can greatly reduce the difficulty of moving the fork. The traditional metal frame design usually relies on the mechanical connection of multiple screws and metal parts. These connections may loosen due to vibration, thermal expansion and contraction in long-term work. Looseness will not only cause unstable movement of the fork, but also cause poor contact, which will affect the power-off capability and reliability of the circuit breaker.

[0004] In addition, since small circuit breakers usually need to be small and light, the metal frame structure must meet the compact design requirements, and it is also required to have anti-loosening and limiting structures to improve the stability of the connection. However, the existing conventional metal frames are difficult to achieve the above effects, which often causes position deviation, loose connection, and even separation of the metal frame and the fork from each other and loss of function during the fork movement process.

[0023] Embodiment 1

[0024] See also Figure 1 and Figure 2 As shown, the present embodiment provides a circuit breaker opening bracket, which includes: a body 100, one end of which is provided with a baffle mounting opening 110; a mounting groove 200, which is arranged inside the body 100, and the mounting groove 200 is connected to the outside world toward the side of the circuit breaker handle to be connected, and the mounting groove 200 includes a receiving portion 210 and at least one clamping portion 220 that are connected to each other, and the circuit breaker handle is inserted into the receiving portion 210 and abuts against the clamping portion 220; a first baffle 300, which is connected to the body 100 and is arranged at one end of the mounting groove 200 in the length direction away from the baffle mounting opening 110; a second baffle, which is detachably connected to the baffle mounting opening 110 through a connecting member, and the first baffle 300 and the second baffle block the two ends of the circuit breaker handle from the first direction X.

[0025] The circuit breaker bracket described in this embodiment can connect the body 100 and the circuit breaker handle through the installation groove 200, so that it is integrated with the circuit breaker, wherein the installation groove 200 is fixed and closed by the first baffle 300 on one side, and the circuit breaker handle is flexibly installed on the other side through the removable second baffle, thereby cooperating with the installation groove 200 to improve the stability of the application process while expanding the scope of use of the application. Compared with the conventional bracket structure at this stage, the present application has significant advantages such as good connection stability, high connection strength, flexible installation and disassembly, simple structure, easy production and processing, low cost and wide application range, and has broad application prospects in this industry.

[0026] See also Figure 1 and Figure 2 As shown, for the convenience of description, in this application, the length direction of the body 100 is defined as the first direction X, the width direction of the body 100 is defined as the second direction Y, and the height direction of the body 100 is defined as the third direction Z, wherein the first direction X, the second direction Y and the third direction Z are mutually perpendicular, and the first direction X and the second direction Y are located in the same horizontal plane. In this application, the body 100 is preferably a steel columnar element, and the mounting groove 200 is provided at the bottom thereof. In actual use, the handle of the circuit breaker can be inserted into the mounting groove 200 by horizontal movement, thereby realizing the connection between the circuit breaker handle and the metal frame of the circuit breaker.

[0027] In this embodiment, a circuit breaker handle is correspondingly inserted into a circuit breaker mouth frame. Specifically, in the installation slot 200 in the present application, the accommodating portion 210 is arranged above the clamping portion 220, wherein the accommodating portion 210 is used to provide a accommodating space for the circuit breaker handle and limit the circuit breaker handle in the second direction Y. The clamping portion 220 is used to cooperate with the circuit breaker handle to achieve the fixation of the relative positions of the two in the third direction Z. Specifically, in order to improve the degree of cooperation between the installation slot 200 and the circuit breaker handle and increase the contact area between the two, the interior of the accommodating portion 210 in this embodiment is configured as a contoured structure identical to the outer surface of the circuit breaker handle, specifically configured as an arc-shaped structure recessed from the installation slot 200 toward the direction away from the circuit breaker. Correspondingly, two clamping parts 220 are provided inside the mounting groove 200 in this embodiment, and the two clamping parts 220 are symmetrically arranged on both sides of the accommodating part 210 along the second direction Y, and the clamping parts 220 extend from the inner surface of the mounting groove 200 toward the direction away from the mounting groove 200. The two clamping parts 220 are located at the same horizontal height. When the circuit breaker handle is inserted into the mounting groove 200, at least part of the circuit breaker handle can be clamped in the two clamping parts 220, thereby realizing the limiting effect of the circuit breaker mouth frame and the circuit breaker in the second direction Y, thereby improving the connection strength and connection stability between the two.

[0028] See also Figure 2 As shown, the first baffle 300 is fixedly connected to the edge of the mounting groove 200. In this embodiment, the first baffle 300 is fixedly connected to the body 100, and is actually an integral arrangement, which can limit the circuit breaker handle in the first direction X. Further, the first baffle 300 can completely cover the end of the mounting groove 200, or can partially cover the end of the mounting groove 200, as long as it can achieve the stop and limit effect on the circuit breaker handle inside it. In other embodiments, the first baffle 300 can also be fixedly connected to the body 100 in other ways, and the utility model does not make specific restrictions on this. In actual use, the circuit breaker handle needs to be horizontally inserted into the mounting groove 200 along the first direction X from the side away from the first baffle 300. When the circuit breaker handle and the first baffle 300 abut against each other, they are moved into place, and the next installation process can be carried out at this time.

[0029] See also Figure 2 As shown, a baffle mounting opening 110 is provided at one end of the main body 100 away from the first baffle 300. The baffle mounting opening 110 is preferably a blind hole, and the baffle mounting hole is arranged above the mounting groove 200. Since the second baffle and the main body 100 are detachably connected, a connecting part is required to plug the second baffle onto the main body 100 through the baffle mounting opening 110. Furthermore, the second baffle in the present embodiment is preferably a steel baffle with the same cross-sectional area as the mounting groove 200, and the connecting piece is preferably a bolt. When the circuit breaker handle is inserted into the mounting groove 200, the connecting hole on the second baffle is aligned with the baffle mounting port 110, and then fixed by bolts, thereby completing the installation process of the second mounting plate. At this time, the circuit breaker handle can be fixed by the side wall of the mounting groove 200, the first baffle 300 and the second baffle at the same time, thereby fundamentally eliminating the problem of relative displacement between the circuit breaker handle and the circuit breaker port metal frame during actual use. In addition, the connecting piece can also be set to other elements or structures that can realize the connection between the second baffle and the body 100, and the utility model does not make specific restrictions on this.

[0030] See also Figure 1 and Figure 2 As shown, the body 100 further includes an extended end bar 130, and the extended end bar 130 extends from the body 100 in a direction away from the mounting groove 200 along a first direction X. In this embodiment, the extended end bar 130 extends horizontally from the upper surface of the body 100 in a direction away from the body 100. For ease of processing and manufacturing, the shape of the extended end bar 130 matches the shape of the upper surface of the body 100, and the extended end bar 130 is fixedly connected to the body 100, and is actually an integral arrangement. In actual use, the extended end bar 130 is used to assist in pushing the circuit breaker handle to close, and the utility model does not impose specific restrictions on the specific shape and structure of the extended end bar 130.
