[0002] Electronic circuit breakers are devices capable of monitoring tasks in automated and digital production processes. They are primarily used for selective protection of DC circuits, protecting power supplies and distribution systems by precisely preventing overcurrent and short circuits. Electronic circuit breakers are designed to provide more precise protection than traditional miniature circuit breakers, especially in scenarios requiring monitoring of 24V control voltage levels and power distribution. They not only provide overload and short-circuit protection but also have diverse remote signaling functions, allowing users to monitor system status anytime, anywhere, thereby achieving fault protection for system components and switch-mode power supplies.

[0022] Beneficial effects

[0023] This invention provides a stability mechanism for an electronic circuit breaker. Compared with the prior art, it has the following advantages:

[0024] (1) The stability mechanism of this electronic circuit breaker involves the circuit breaker body driving the outer wall of the positioning seat to fit into the receiving groove, the circuit breaker body driving the bottom wall of the lower limiting seat to fit into the inner wall of the lower positioning groove, the rear bottom wall of the circuit breaker body to fit into the top wall of the lower moving seat, the lower positioning rod entering the inner wall of the bottom limiting hole through the through-hole for limiting, the adjusting handle driving the fastening screw to rotate, the upper moving seat driving the upper limiting slider to slide downward in the inner wall of the limiting slide groove, the upper moving seat driving the upper positioning rod to enter the inner wall of the top limiting hole, the inner wall of the upper positioning groove at the bottom of the upper moving seat fitting into the inner wall of the top limiting seat, and the upper moving seat... The descent of the screw causes the circuit breaker body to slide downwards. The circuit breaker body then causes the lower moving seat to slide within the inner wall of the mounting bracket and the lower limit slider to slide downwards within the inner wall of the limit groove. This causes the lower moving seat to compress the spring and enter the mounting groove. As the fastening screw descends further, the spring's elasticity pushes the lower moving seat and the circuit breaker body to move, simultaneously abutting and fixing the circuit breaker body from both the top and bottom. When installing and fixing the electronic circuit breaker, this abutting and fixing mechanism improves the overall installation stability and prevents it from shaking or becoming unstable. It also maintains a stable installation posture even under external forces. Attached Figure Description

At the same time, the fastening screw 514 drives the upper moving seat 513 to abut and fix the top of the circuit breaker body 2, which can maintain the overall stability of the circuit breaker body 2. When subjected to external force, it can prevent it from shaking, maintain its stable installation posture, and reduce the occurrence of safety hazards.

[0035] Example 2:

[0036] Please see Figure 1-4This embodiment provides a technical solution based on Embodiment 1: the inner wall of the through 53 is slidably connected to the outer wall of the corresponding lower positioning rod 57, the outer wall of the lower positioning rod 57 is in contact with the inner wall of the lower limiting hole 511, the outer wall of the lower moving seat 51 is slidably connected to the inner wall of the mounting bracket 4, the outer wall of the lower moving seat 51 is fixedly installed with a lower limiting slider 52, the outer wall of the lower limiting slider 52 is slidably connected to the inner wall of the corresponding limiting groove 58, the outer wall of the lower limiting seat 510 is in contact with the inner wall of the lower positioning groove 55, and the upper moving seat 513...

[0037] In this embodiment of the utility model, the purpose of this arrangement is that a fixing plate 1 is fixedly installed on the rear wall of the mounting bracket 4 and is screwed into the screw groove 3 for screwing and fixing. The entire device can be installed and fixed in a fixed position. The top of the adjustment handle 517 has a hexagonal groove, and the adjustment handle 517 can also be operated and rotated with the help of tools such as screwdrivers.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] During operation, when installing and fixing the circuit breaker body 2, first move the circuit breaker body 2 to move the positioning seat 518 close to the inner wall of the receiving groove 59 at the front of the mounting bracket 4, so that the outer wall of the positioning seat 518 fits against the inner wall of the receiving groove 59. Then slide the circuit breaker body 2 downward to move the bottom wall of the lower limiting seat 510 to fit against the inner wall of the lower positioning groove 55 on the top wall of the lower moving seat 51. The bottom wall of the rear of the circuit breaker body 2 fits against the top wall of the lower moving seat 51. The lower positioning rod 57 enters the inner wall of the limiting hole 511 at the bottom through the through hole 53 and is limited. Rotate the adjusting handle 517 to drive the fastening screw 514 to rotate. When the fastening screw 514 rotates, it drives the upper moving seat 513 to slide downward along the inner wall of the mounting bracket 4 and drives the upper limit slider 512 to slide downward in the inner wall of the limiting slide groove 58. When the upper moving seat 513 slides downward, it drives the upper positioning rod 516 to enter the top. The upper positioning groove 515 at the bottom of the upper moving seat 513 is in contact with the inner wall of the upper positioning groove 510 at the top. As the upper moving seat 513 descends, it causes the circuit breaker body 2 to slide downward. The circuit breaker body 2 causes the lower moving seat 51 to slide in the inner wall of the mounting bracket 4 and causes the lower limiting slider 52 to slide downward in the inner wall of the limiting groove 58. This causes the lower moving seat 51 to squeeze the spring 54 into the mounting groove 56. As the fastening screw 514 descends further, the lower moving seat 51 and the circuit breaker body 2 are pushed back to move under the elastic action of the spring 54. The circuit breaker body 2 is simultaneously abutted and fixed from the top and bottom. The movable fixing plate 1 drives the entire device to place the circuit breaker body 2 into the installation position. It is then fixed by screws through the screw groove 3. After the circuit breaker body 2 is installed, the overall stability is high and there will be no shaking under the action of external force.
