[0030] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a circuit breaker device with optimized operating force through lever design, including a first housing 1, a second housing 2 detachably mounted on the side of the first housing 1, a handle 3 rotatably connected to the inner wall of the first housing 1, a control plate 4 rotatably connected to the inner wall of the first housing 1, an iron suction column 6 installed inside the first housing 1, a coil 5 sleeved on the surface of the iron suction column 6, a release plate 7 rotatably connected to the inner wall of the first housing 1, a fixed column 8 fixedly connected to the inner wall of the first housing 1, a rotating plate 9 rotatably connected to the surface of the fixed column 8, a lever 10 fixedly connected to the side of the rotating plate 9 near the control plate 4, and an arc-shaped rod 12 mounted on the lower surface of the rotating plate 9. By setting the fixed column 8, the rotating plate 9 can be connected to the first housing 1, while ensuring that the rotating plate 9 can rotate. By setting the arc-shaped rod 12, the rotating plate 9, the fixed column 8, and the lever 10, the rotation of the control plate 4 can be controlled through the lever action of the release plate 7.

[0031] The following is a detailed explanation of its overall setup and function.

[0032] Reference Figures 1-5 As shown in this embodiment: A rectangular plate 11 is fixedly connected to the side of the rotating plate 9 near the arc-shaped rod 12. The rectangular plate 11 is fixedly connected to the arc-shaped rod 12 and fits tightly against the inner wall of the first housing 1. By setting the rectangular plate 11, the arc-shaped rod 12 and the rotating plate 9 can be connected, thereby controlling the rotation of the rotating plate 9 through the arc-shaped rod 12. A fixed plate 13 is fixedly connected to the inner wall of the first housing 1. A bent rod 14 is slidably connected to the inner wall of the fixed plate 13 and is fixedly connected to the rectangular plate 11. The bent rod 14, which is slidably connected to the inner wall of the fixed plate 13, can move. By setting the bent rod 14, the position of the rectangular plate 11 can be restricted. A spring 15 is sleeved on the surface of the bent rod 14. The two ends of the spring 15 are fixedly connected to the rectangular plate 11 and the fixed plate 13, respectively. By setting the bent rod 14, the position of the spring 15 can be restricted, and by setting the spring 15, the position of the rectangular plate 11 can be restricted.

[0033] Both sides of the first housing 1 are fixedly connected to a first arc-shaped plate 16. The first arc-shaped plate 16 facilitates the positioning of the first housing 1 during circuit breaker assembly. Both sides of the second housing 2 are fixedly connected to a second arc-shaped plate 18. The second arc-shaped plate 18 facilitates the positioning of the second housing 2 during circuit breaker assembly. A positioning rod 17 is fixedly connected to the side of the first arc-shaped plate 16 closest to the second arc-shaped plate 18, and the positioning rod 17 is slidably connected to the inner wall of the second arc-shaped plate 18. The positioning rod 17 allows for control of the relative position between the first arc-shaped plate 16 and the second arc-shaped plate 18, and also restricts their positions.

[0034] The working principle is as follows: During the assembly of the circuit breaker, the second housing 2 is moved, causing the second arc-shaped plate 18 to move closer to the positioning rod 17 on the first arc-shaped plate 16, thus positioning the first housing 1 and the second housing 2. Then, the first housing 1 and the second housing 2 are fixed. When a short circuit occurs in the circuit, the coil 5 generates a magnetic force that attracts the iron-attracting column 6, thereby controlling the iron-attracting column 6 to move closer to the release plate 7, pushing the release plate 7 to rotate closer to the arc-shaped rod 12. At this time, the arc-shaped rod 12 pushes the rotating plate 9 to rotate on the surface of the fixed column 8 through the rectangular plate 11. Simultaneously, the lever 10 moves the control plate 4, causing the handle 3 to rotate on the inner wall of the first housing 1 and the second housing 2, thus cutting off the circuit. Afterwards, the coil 5 loses its magnetic force, and under the action of the spring 15, the bent rod 14 slides on the inner wall of the fixed plate 13, simultaneously pushing the rectangular plate 11 back to its original position. By setting up the arc-shaped rod, the rectangular plate 11, and the rotating plate 9, the lever 10 can be driven to move the control plate 4 during the movement of the iron suction column 6, thereby achieving the effect of circuit breaking. This reduces the complexity of the circuit breaker control circuit disconnection mechanism and facilitates the process of controlling the circuit disconnection. By setting up the first arc-shaped plate 16, the positioning rod 17, and the second arc-shaped plate 18, it is convenient to position the first housing 1 and the second housing 2 during the assembly of the circuit breaker. At the same time, it is convenient to restrict the position of the first housing 1 and the second housing 2, thereby improving the efficiency of assembling the circuit breaker.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
