[0002] With the rapid development of the Internet of Things (IoT) and smart home technologies, the market demand for smart electrical equipment is constantly increasing. The emergence of smart circuit breakers is precisely to address the shortcomings of traditional circuit breakers, achieving comprehensive monitoring and management of the power system by integrating advanced sensors, communication modules, and intelligent algorithms.

[0003] The current intelligent circuit breaker is installed on a track within the distribution box using a mounting structure consisting of a mounting port and a sealing plate. The sealing plate is connected to the intelligent circuit breaker via an elastic structure. Under the elastic support of this structure, the sealing plate flexibly controls the opening size of the mounting port, thus enabling the intelligent circuit breaker to be installed and removed from the track. However, the existing connection between the elastic structure and the sealing plate is closed. Replacing or adjusting the elastic structure requires disassembling the entire backplate of the intelligent circuit breaker, which is not only cumbersome but also damages the electrical connection structure. Therefore, this solution proposes a smart electrical circuit breaker to address these issues. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: This utility model provides the following... Figure 1 - Figure 3 The smart circuit breaker device shown includes a smart circuit breaker body 1. The back of the smart circuit breaker body 1 has an installation port 102. The top and bottom of the smart circuit breaker body 1 both have wiring holes 101. Multiple wiring holes 101 are used for electrical connection of connecting wires. An antenna 3 is provided on the top of the smart circuit breaker body 1. A control switch 2 is provided on the front of the smart circuit breaker body 1.

[0031] It should be noted that the design of the intelligent circuit breaker body 1 in this solution is the same as that of the intelligent air switch with model AXB2-63-2LD (RS485). Its DC rated voltage is 1000V and below, the rated current of the trip unit is 1321A, and the leakage current action time is 0.26s. A threaded connection structure is set on the front of the intelligent circuit breaker body 1 at the wiring hole 101, so as to fix the threaded part inserted into the wiring hole 101, ensuring that the connector can achieve a stable electrical connection with the intelligent circuit breaker body 1 after being inserted into the wiring hole 101.

[0032] Specifically, a placement groove is provided on the back of the intelligent circuit breaker body 1, and the inner wall of the bottom of the mounting port 102 is connected to the placement groove. The placement groove is located at the bottom of the intelligent circuit breaker body 1 and in the middle area.

[0033] Example 2: This utility model provides the following... Figure 4 - Figure 5 The sealing plug 4 and the elastic adjustment mechanism shown are applied to a smart circuit breaker device in Embodiment 1. Multiple sets of sealing plugs 4 are horizontally and symmetrically connected to both ends of the bottom of the mounting port 102. The top of the sealing plug 4 is inserted through the bottom end of the smart circuit breaker body 1 and the placement groove and then passes into the mounting port 102. The sealing plug 4 is used to adjust the opening size of the mounting port 102.

[0034] It should be noted that the sealing plate 4 is a rectangular plate structure with a hook-shaped top, which can better hook onto the side wall of the track plate. This, together with the inner wall of the top of the mounting port 102, enables the connection between the intelligent circuit breaker body 1 and the track. The middle part of the sealing plate 4 is inserted into the placement groove, and after passing through the placement groove, the sealing plate 4 can slide at the bottom of the intelligent circuit breaker body 1.

[0035] Specifically, the side wall of the slot is provided with a support groove, and a support slider 401 is fixedly connected to one side of the sealing plate 4. The support slider 401 is slidably inserted into the support groove. A pull port 403 is provided at the bottom of the sealing plate 4. The pull port 403 is used for the insertion and pulling of the sealing plate 4.

[0036] It should be noted that the contact surface between the supporting slider 401 and the supporting groove is an arc-shaped surface. This reduces the contact area between the supporting slider 401 and the supporting groove, ensuring that the supporting slider 401 slides with the least possible friction. When the blocking plate 4 is in its natural state, the pull port 403 is located at the bottom of the intelligent circuit breaker body 1, which facilitates the operation of pulling the blocking plate 4 through the pull port 403. This also makes it easy to remove the locking mechanism between the blocking plate 4 and the track, and facilitates the disassembly of the intelligent circuit breaker body 1 at the track.

[0037] The elastic adjustment mechanism is located at the intersection of the sealing plate 4 and the mounting port 102. The elastic adjustment mechanism is used to elastically support the sealing plate 4 near the center of the mounting port 102. The elastic adjustment mechanism is located in the placement groove.

[0038] Specifically, a sliding plate 402 is provided on the other side of the blocking plate 4, and an opening is provided in the middle of the sliding plate 402. The sliding plate 402 is slidably sleeved with the elastic adjustment mechanism, which includes:

[0039] Guide slide rod 6, one end of which is fixedly connected to the inner wall of the bottom of the placement groove, and sliding plate 402 is slidably sleeved with guide slide rod 6 through an open opening;

[0040] The top support spring 7 is sleeved on the outer wall of the guide slide rod 6, and the top support spring 7 is used to push the sliding plate 402 upward.

[0041] It should be noted that after the sliding plate 402 is slidably connected to the guide slide rod 6 through the open opening, it prevents the sliding plate 402 from tilting when it moves vertically under the elastic support of the top support spring 7. At the same time, it provides an opening for disassembling the sliding plate 402 and the guide slide rod 6, so as to facilitate the disassembly, replacement and maintenance of the top support spring 7. Under the action of the top support spring 7, the sealing plate 4 is in the state of being closest to the installation opening 102 in its natural state, that is, the installation opening 102 is in the state of being fully open at its minimum.

[0042] Example 3: This utility model provides the following... Figure 6 The sealing cover 5 shown is applied in Embodiment 1 and Embodiment 2. The sealing cover 5 is detachably connected to the bottom of the intelligent circuit breaker body 1. The sealing cover 5 is used to block the opening and closing of the insertion plate 4 and the installation port 102. The sealing cover 5 is sleeved on the groove of the placement slot.

[0043] Specifically, a pressing strip 501 is fixedly connected to one side of the closed cover plate 5. The pressing strip 501 is inserted into the inner wall of the placement groove, and the pressing strip 501 is used to press the sliding plate 402 to move closer to the supporting slider 401. Mounting plates 502 are fixedly connected to both sides of the closed cover plate 5. The mounting plates 502 are used for the detachable fixing of the closed cover plate 5 and the intelligent circuit breaker body 1.

[0044] It should be noted that the mounting plate 502 can be disassembled and installed from the intelligent circuit breaker body 1 by means of screws. With this setting, the sealing structure at the mounting plate 502 is separated from the back plate structure of the intelligent circuit breaker body 1, and the structure of other parts of the intelligent circuit breaker body 1 will not be affected when the mounting plate 502 is disassembled.

[0045] The sealing cover 5, through the setting of the extrusion strip 501, allows the extrusion strip 501 to press the sliding plate 402 towards the support slider 401 after the sealing cover 5 is connected to the intelligent circuit breaker body 1. This ensures that the support slider 401 makes stable contact and slides with the support groove, further preventing the sealing plate 4 from tilting when sliding with the assistance of the top support spring 7, and ensuring a stable connection between the intelligent circuit breaker body 1 and the track.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
