[0026] Embodiment 1

[0027] like Figures 1 to 4 As shown, the first embodiment of the present invention provides a smart IoT type stable circuit breaker, and the circuit breaker 1600 structure has the advantages of high installation stability and preventing the wiring harness from falling off; specifically, it includes a base 100 and a cover 200; the front side of the base 100 is provided with a mounting groove 110 for fixing the circuit breaker 1600, and the circuit breaker 1600 can be placed in the mounting groove 110 during installation. In order to prevent the circuit breaker 1600 from falling off, each side wall of the mounting groove 110 is provided with a positioning column 300 that penetrates the outer side of the base 100, and the positioning column 300 A spring member is sleeved on the upper part, and a supporting end is provided at one end of the positioning column 300, and a positioning end is provided at the other end. When the face shell 200 is inserted into the outer side of the base 100, the supporting end of the positioning column 300 abuts against the inner wall of the face shell 200, and the positioning end is inserted into the positioning hole on the periphery of the circuit breaker 1600; after the face shell 200 and the base 100 are assembled, the inner wall of the rear shell 200 abuts against the supporting end of the end of the positioning column 300, so that the positioning end at the other end of the positioning column 300 can be inserted into the positioning hole on the periphery of the circuit breaker 1600 to prevent the circuit breaker 1600 from falling off.

[0028] like Figures 1 to 4As shown, in order to provide protection for the circuit breaker 1600, in this embodiment, the cover 200 is covered on the outside of the base 100 to cover the circuit breaker 1600, and the end of the cover 200 is provided with an L-shaped wiring slot 210 corresponding to the wiring terminal of the circuit breaker 1600, and the wiring slot 210 extends along the outer side of the cover 200 to the upper end surface; the bottom wall of the wiring slot 210 is provided with a lower pressing plate 400, and the upper end of the lower pressing plate 400 is provided with a plurality of spaced pressing grooves 410, and the upper end of the wiring slot 210 is hinged with an L-shaped inspection device for opening and closing the wiring slot 210. A repair cover 500, wherein an upper wire pressing plate 600 is disposed on the inner wall of the inspection cover 500, and a wire pressing protrusion 610 arranged one-to-one with the wire pressing groove 410 is disposed on the side of the upper wire pressing plate 600 opposite to the lower wire pressing plate 400, and the wire pressing protrusion 610 is elastic, and a lead-out wire groove 510 arranged opposite to each wire pressing groove 410 is disposed at the end of the inspection cover 500, and when the inspection cover 500 closes the wiring slot 210, the wire pressing protrusion 610 is inserted into each wire pressing groove 410, and at the same time, each lead-out wire groove 510 is arranged one-to-one opposite to the wire pressing groove 410.

[0029] like Figures 1 to 4 As shown, through the above-mentioned arrangement, the base 100 and the face shell 200 in this embodiment are assembled for sealing and installing the circuit breaker 1600, so as to protect the installed wiring harness and prevent the circuit breaker 1600 from being exposed in the installation environment. The wiring slot 210 arranged on the face shell 200 is used to lead out the wiring harness connected to the circuit breaker 1600. After the wiring harness is led out, it can be inserted into each wire pressing groove 410. When the inspection cover 500 is closed, each wire pressing protrusion 610 on the inner side of the inspection cover 500 is used to be inserted into the wire pressing groove 410, so as to fix the wiring harness and prevent the wiring harness from falling off. The wiring harness is led out from each lead-out wire groove 510 of the inspection cover 500, which reduces the risk of the wiring harness of the circuit breaker 1600 falling off and the risk of foreign matter adhering to the wiring position of the circuit breaker 1600, thereby improving the reliability of the operation of the circuit breaker 1600.

[0030] like Figure 1 to Figure 2As shown, in actual application, in addition to connecting the power harness, the circuit breaker 1600 also needs to connect the communication line to control the circuit breaker 1600. In order to improve the stability of the connection of the communication harness, in this embodiment, a communication bayonet 220 is provided on the outer side of the surface shell 200 opposite to the wiring slot 210. The communication bayonet 220 is arranged opposite to the communication interface located on the end face of the circuit breaker 1600. The communication bayonet 220 is provided with a detachable elastic card block 700. Both sides of the card block 700 are provided with V-shaped buckle parts 710 that fit the locking grooves of the side walls of the communication bayonet 220. The card block 700 is also provided with a harness opening 720 that passes through the card block 700. After the card block 700 is inserted into the communication bayonet 220, the harness opening 720 is shrunk due to lateral pressure. In this way, the communication harness used to connect the communication interface of the circuit breaker 1600 can pass through the harness port 720. After the connector on the communication harness is inserted into the communication interface, the card block 700 can be inserted into the communication card port 220, and the buckle portion 710 is used to fix the card block 700 to prevent the installation structure of the communication harness from falling off. At the same time, after the card block 700 is inserted into the communication card port 220, the harness port 720 is subjected to lateral pressure, which can form a lateral limit on the harness to prevent the harness from loosening, thereby achieving the purpose of tightening the harness.

[0031] like Figure 4 As shown, in order to improve the stability of the card block 700 being inserted into the communication card port 220, one end of the buckle part 710 in this embodiment is connected to the side of the card block 700 inserted into the communication card port 220, and the other end is provided with a locking card protrusion 711, and the locking card protrusion 711 can be inserted into the buckle lock groove 221 located on both sides of the opening of the communication card port 220. In this way, after the buckle part 710 is inserted into the engaging groove of the side wall of the communication card port 220, the locking card protrusion 711 can be inserted into the buckle lock groove 221, which can prevent the buckle part 710 from being loosened on the one hand, and facilitate the technician to clamp the two buckle parts 710 with the help of tools so that the card block 700 can be taken out smoothly on the other hand. At the same time, in this embodiment, an elastic telescopic column 800 is also provided in the card block 700, and the two ends of the telescopic column 800 pass through the side wall of the card block 700 and abut against the inner side of the buckle part 710. When the buckle part 710 is inserted into the engaging groove, the elastic telescopic column 800 elastically supports the side wall of the buckle part 710, thereby preventing the buckle part 710 from being separated from the engaging groove. During disassembly, the technician can use a clamping tool to clamp the two buckle parts 710 to smoothly remove the card block 700, which is convenient for repairing the line.

[0032] like Figures 1 to 3As shown, the circuit breaker 1600 will generate a lot of heat when used for a long time, especially when the ambient temperature is high, the heat cannot be dissipated and will cause the circuit breaker 1600 to be damaged. In this embodiment, heat dissipation ports 230 are provided on the outer surfaces of the face shell 200 corresponding to both sides of the wiring slot 210. The heat dissipation ports 230 are provided with a filter 900. A sealing plate 1000 is slidably provided in the heat dissipation port 230 corresponding to the outer side of the filter 900, and a sliding portion is provided on the outer side of the sealing plate 1000. When the circuit breaker 1600 is used in a high temperature environment, the sealing plate 1000 can be opened to dissipate the internal heat, which is beneficial to cooling. When the circuit breaker 1600 is used in a low temperature environment, the sealing plate 1000 can be slid to close the heat dissipation port 230 to keep a certain temperature inside the circuit breaker 1600.

[0033] like Figures 1 to 3 As shown, when the face shell 200 and the base 100 are assembled, the abutting end of the positioning column 300 needs to be inserted into the inner wall of the face shell 200. In this embodiment, an assembly bevel 240 is provided on the inner side of the opening of the face shell 200 corresponding to the position of each positioning column 300. When the face shell 200 and the base 100 are assembled, the abutting end of each positioning column 300 is inserted into the inner wall of the face shell 200 along the assembly bevel 240. Each edge of the inner top wall of the face shell 200 is provided with a fixing platform that abuts against the upper edge of the circuit breaker 1600, and the fixing platform is a right-angle structure. The assembly bevel 240 can make the abutting end of the face shell 200 and the end of the positioning column 300 cooperate more smoothly, avoiding jamming during assembly. After the face shell 200 is installed in the base 100, each fixing platform in the face shell 200 can stably abut against the upper end of the circuit breaker 1600, further improving the stability of the circuit breaker 1600.

[0034] like Figures 1 to 3 As shown, in order to prevent the face shell 200 from being separated from the base 100 after being assembled, the present embodiment provides locking columns 1400 on two opposite outer sides of the periphery of the base 100, and the locking columns 1400 are sleeved with return springs to make the locking columns 1400 protrude from the outer peripheral surface of the base 100, and the inner wall of the face shell 200 is provided with a locking groove corresponding to the position of the locking column 1400, and the outer side surface of the face shell 200 is provided with an unlocking button 1500 that passes through the locking groove. After the face shell 200 and the base 100 are assembled, the ends of each locking column 1400 are inserted into a corresponding locking groove, and pressing the unlocking button 1500 can make the locking column 1400 withdraw from the locking groove; in this way, by locking the automatically locked face shell 200, the stability of the face shell 200 is improved, and when disassembly is required, the face shell 200 can be unlocked by pressing the unlocking button 1500 so as to disassemble the face shell 200, which is convenient for technicians to operate.

[0035] Embodiment 2

[0036] like Figures 1 to 3As shown, the present embodiment further optimizes the inspection cover 500 for opening and closing the wiring slot 210. As mentioned above, the inspection cover 500 provided on the face shell 200 in the present embodiment is used for opening and closing the wiring slot 210. In order to improve the stability of the inspection cover 500 in closing the wiring slot 210, the present embodiment provides tightening bolts 1100 on both sides of the opening of the wiring slot 210 corresponding to the end surface of the face shell 200. The tightening bolts 1100 are sleeved with isolation rings, and the lower end of the inspection cover 500 is provided with a locking groove 530 for the tightening bolts 1100 to be inserted into. That is, when the inspection cover 500 is closed, the tightening bolts 1100 are inserted into the locking groove 530. After the tightening bolts 1100 are pre-tightened, the inspection cover 500 is fixed through the isolation ring to prevent the inspection cover 500 from opening. A torsion spring can also be provided at the position where the inspection cover 500 and the face shell 200 are rotatably assembled, so that the inspection cover 500 can be automatically opened after the tightening bolts 1100 are loosened.

[0037] like Figures 1 to 3 As shown, in order to prevent external moisture and the like from invading the interior of the circuit breaker 1600 when in use, the present embodiment provides sealing protrusions 520 on both sides of the inner wall of the inspection cover 500. When the inspection cover 500 is closed, the sealing protrusions 520 can be inserted into the sealing grooves 250 provided on both sides of the corresponding wiring grooves of the face shell 200. The sealing protrusions 520 and the sealing grooves 250 are utilized to achieve sealing of the interior of the face shell 200, thereby achieving a higher installation sealing performance.

[0038] like Figures 1 to 3 As shown, since the wiring harness of the circuit breaker 1600 needs to be led out from the lead-out wire slot 510, in some embodiments, the lead-out wire slot 510 needs to be in a closed state when it is idle without wiring. Therefore, in this embodiment, a closing piece 1200 is slidably provided in each lead-out wire slot 510 of the inspection cover 500, and an elastic member for elastically supporting the closing piece 1200 is provided in the inspection cover 500. The closing piece 1200 closes the lead-out wire slot 510 under the action of the elastic member. In this way, the closing piece 1200 can automatically close or open the lead-out wire slot 510 according to whether the lead-out wire slot 510 is connected to a line, thereby automatically closing the lead-out wire slot 510, which is convenient for operation and use.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
