The utility model is used to enable the circuit breakers inside the cabinet to be managed in a unified manner, and the cables can be hidden in the box body, thereby improving the overall tightness and safety of the device while making the interior of the cabinet more beautiful.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned easy-to-use LPWAN power circuit breaker has the following problems: the box body of the circuit breaker device is composed of an integrated structure, which is inconvenient to disassemble after installation and fixation. At the same time, there is no corresponding dust-proof structure on the top of the box body, and dust can easily generate static electricity, causing a short circuit. For this reason, we propose an easy-to-use LPWAN power circuit breaker. Utility Model Content

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. In the utility model, through the provided jack, positioning pin and movable slot, when rerouting, it is necessary to remove the main body of the circuit breaker from the slot, manually pull the main body of the circuit breaker outward, use the positioning pin to compress the limit block and the spring to make the conical pin provided at the front end of the limit block leave the notch provided on the outer wall of the positioning pin, and pull the positioning pin out from the inner wall of the slot to separate the main body of the circuit breaker from the outer wall of the mounting base, so that the structure is convenient for adjusting the line without disassembling the circuit breaker as a whole, and the operation is convenient.

[0026] Example 1: Figure 1 to Figure 5 As shown, the present embodiment proposes a convenient-to-use LPWAN power circuit breaker, comprising a mounting base plate 1, a transparent dust cover 3 and a circuit breaker body 5. A card slot 11 is provided at the center of the mounting base plate 1, and jacks 10 are symmetrically provided around the inner wall of the card slot 11. The side walls of the jacks 10 are provided with movable slots 15. The inner walls of the movable slots 15 are provided with limit blocks 13, and the outer walls of the limit blocks 13 are provided with springs 14. The mounting base plate 1 is movably provided with a circuit breaker body 5 through the card slot 11, and a main switch 6 is provided on the outer wall of the circuit breaker body 5. The outer wall of the circuit breaker body 5 close to the card slot 11 is provided with a positioning pin 12, and the positioning pin 12 matches the jack 10. The outer wall of the mounting base plate 1 is movably provided with a transparent dust cover 3 through a bearing.

[0027] In this embodiment, the outer wall of the positioning pin 12 is provided with a concave structure, and the front end of the limiting block 13 is provided with a conical locking pin, and the locking pin and the concave structure fit each other.

[0028] In this embodiment, the slot 11 is a rectangular groove structure, and the outer wall of the switch body 5 close to the installation base plate 1 fits with the slot 11 .

[0029] In this embodiment, the outer wall of the mounting base plate 1 is provided with thread holes, and the mounting base plate 1 is mounted and fixed by means of bolts 2 and the thread holes.

[0030] Specific as Figure 1 , Figure 4 and Figure 5 As shown, when the structure is used, when the circuit breaker body 5 needs to be disassembled, the circuit breaker body 5 is manually pulled outward, and the positioning pin 12 is used to compress the limit block 13 and the spring 14 so that the conical pin set at the front end of the limit block 13 leaves the recessed position set on the outer wall of the positioning pin 12, and the positioning pin 12 is pulled out from the inner wall of the slot 11, so that the circuit breaker body 5 is separated from the outer wall of the mounting base 1, so that the structure is convenient for adjusting the line without disassembling the circuit breaker as a whole, and the operation is convenient.

[0031] Embodiment 2: A fixing block 4 is provided at one end of the transparent dust cover 3 , and a fixing hole 9 matching the fixing block 4 is provided on the outer wall of the mounting base plate 1 .

[0032] In this embodiment, the front end of the fixing block 4 is rounded, and the fixing block 4 is made of magnetic material.

[0033] In this embodiment, the outer walls on both sides of the transparent dust cover 3 are provided with heat dissipation openings 8 at equal intervals, and the heat dissipation openings 8 are in a straight line shape and tilted downward.

[0034] In this embodiment, the circuit breaker body 5 is composed of two upper and lower box bodies, which are fixed together by screws 7 .

[0035] Specific as Figure 1 , Figure 2 and Figure 3 As shown, when using this structure, the transparent dust cover 3 is flipped over so that the fixing block 4 is magnetically engaged with the inner wall of the fixing hole 9, so that the transparent dust cover 3 completely covers and isolates the circuit breaker body 5, thereby protecting the internal electronic components from dust and preventing static electricity caused by dust from causing a short circuit in the circuit. At the same time, the heat dissipation port 8 arranged on the side wall of the transparent dust cover 3 can dissipate heat therefor. Through the inclined I-shaped structure of the heat dissipation port 8, dust, water vapor, etc. can be effectively prevented from flowing back into the interior of the transparent dust cover 3. This structure can effectively prevent dust and heat dissipation of the circuit breaker components and prevent static electricity from affecting the operation of the internal electronic components.

[0036] Working principle: Fix the installation base plate 1 in the cabinet by bolts 2, manually align the positioning pin 12 set on the back of the air switch body 5 with the socket 10 and insert it, so that the outer walls on both sides of the positioning pin 12 compress the limit block 13 and the spring 14, and wait for the groove set on the outer wall of the positioning pin 12 to move to the side of the limit block 13. The pressure generated by the deformation of the spring 14 makes the conical bayonet pin set at the front end of the limit block 13 engage in the groove to fix the positioning pin 12, so that the air switch body 5 is fixed on the inner wall of the slot 11, and then flip it over. The transparent dust cover 3 magnetically engages the fixing block 4 with the fixing hole 9, so that the transparent dust cover 3 completely covers the card slot 11 to prevent the air switch body 5 from dust. At the same time, the heat dissipation ports 8 arranged on both sides of the transparent dust cover 3 are used for heat dissipation. The device can prevent dust and dissipate heat for the air switch to avoid short circuit caused by static electricity. At the same time, when it is necessary to disassemble the wiring, you only need to pull the air switch body 5 out of the card slot 11, remove the screws 7 to open the air switch body 5, so as to facilitate the wiring and repair of the internal lines of the air switch body 5.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
