Detailed Description

The present invention will now be described more fully hereinafter with reference to the accompanying examples.

Referring to the attached drawing 1, the intelligent miniature circuit breaker based on the internet of things comprises a shell and a circuit breaker main body structure positioned in the shell, wherein the shell comprises a base 1 and an upper cover 2.

With reference to fig. 2, the two opposite sides of the base 1 and the upper cover 2 are respectively formed with a sealing groove 3, the corresponding sealing grooves 3 are connected with each other and are inserted with sealing pieces 4, and the bottom of the sealing groove 3 is fixedly provided with a sealing strip. When the circuit breaker is assembled, the sealing sheet 4 is firstly inserted into the sealing groove 3 in the base 1, then the upper cover 2 is buckled on the base 1, the sealing sheet 4 is also inserted into the sealing groove 3 of the upper cover 2, and at the moment, the two sides of the sealing sheet 4 are abutted against the sealing strips at the bottom of the corresponding sealing groove 3, so that the upper cover 2 and the base 1 can be well sealed.

Referring to fig. 3, C-shaped slots 5 are formed in the other two opposite sides of the base 1 and the upper cover 2, and strip-shaped rubber pads 6 are fixedly arranged on the sides, contacting with each other, of the openings of the slots 5. The one end of draw-in groove 5 is sealed and the other end runs through, and the shaping has sliding groove 7 on the base 1, and sliding groove 7 and the open end of draw-in groove 5 intercommunication combine figure 4, and it is provided with shutoff board 8 to slide in the sliding groove 7, and the shaping has anti-skidding stripe 9 on the shutoff board 8, fixedly connected with thrust spring 10 between the one end inner wall of shutoff board 8 and sliding groove 7. The blocking plate 8 abuts against one end of the sliding groove 7 under the pushing of the thrust spring 10, so that one end of the opening of the clamping groove 5 is blocked.

After the upper cover 2 is fastened on the base 1, the corresponding openings of the two clamping grooves 5 are connected, and the corresponding rubber pads 6 are also abutted. The two corresponding clamping grooves 5 are internally provided with H-shaped connecting strips 11 in a penetrating manner, the connecting strips 11 are made of metal, and the end parts of the connecting strips 11 are provided with hooking holes 12. After the assembly personnel inserted connecting strip 11 in the draw-in groove 5 that corresponds, connecting strip 11 can be connected upper cover 2 and base 1, when maintenance personal torn open the casing, can utilize hooked instrument to hook the hook and get hole 12 and pull out connecting strip 11, and assembly and dismantlement are all comparatively convenient.

The working principle of the embodiment is as follows: in this embodiment, the connecting strip 11 first plays a role of connecting the upper cover 2 and the base 1, and since the rubber pad 6 has elasticity, the connecting strip 11 will apply pressure to the rubber pad 6 after connecting the upper cover 2 and the base 1, so that the rubber pad 6 is in tight contact and has high sealing performance, and meanwhile, the rubber pad 6 will apply a reaction force to the connecting strip 11, so that the connecting strip 11 is kept stable; secondly, the connecting strip 11 also seals the gap between the upper cover 2 and the base 1, thereby ensuring good sealing performance. Simultaneously the other both sides of casing provide good leakproofness by the cooperation of gasket 4 and seal groove 3, prevent that the dust from entering into in the casing, cause the influence to the heat dissipation of this circuit breaker. The circuit breaker in the embodiment is not suitable for bolt connection, and is very convenient to assemble or disassemble.

The above, only do the preferred embodiment of the present invention, not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
