[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] The utility model provides an intelligent automatic circuit breaker, such as Figure 1-Figure 4 As shown, the circuit breaker includes a circuit breaker body 1, on which is a socket 11 for connecting a wire; the circuit breaker also includes a mounting frame 2 arranged at a position of the circuit breaker body 1 corresponding to the socket 11, a through hole 21 opened at a position of the mounting frame 2 corresponding to the socket 11, a rubber sleeve 3 fixedly connected in the through hole 21 and connected to the socket 11 for protecting the wire and the socket 11, and a closing structure 4 arranged at the outer edge of the circle of one end of the rubber sleeve 3 away from the socket 11 for tightening the circle of the rubber sleeve 3.

[0029] When in use, the mounting frame 2 is first placed on the circuit breaker body 1, and the rubber sleeve 3 set in the through hole 21 is aligned with the socket 11, and then the connected wire is passed through the rubber sleeve 3 and inserted into the corresponding socket 11. Then, according to the thickness of the rubber sleeve 3, the closing structure 4 is adjusted, and the ring of the rubber sleeve 3 away from the socket 11 is tightened by the closing structure 4 and tightly attached to the wire. At this time, under the firm fit of the rubber sleeve 3, it can be ensured that the wire can be firmly plugged into the corresponding socket 11 to reduce the risk of the wire falling off. At the same time, the tightening of the rubber sleeve 3 can achieve the sealing of the socket 11, thereby reducing the entry of external dust or other impurities into the socket 11, so as to reduce the damage to the circuit breaker body 1, and further reduce the occurrence of problems such as poor electrical contact and reduced insulation performance. When it is necessary to remove the wire, it is only necessary to tighten the rubber sleeve 3 ring by the contact closing structure 4, and then pull the rubber sleeve 3 to expand the rubber sleeve 3 ring, so that the wire can be easily pulled out from the corresponding socket 11, and the use process is convenient and simple.

[0030] Specifically, the closing structure 4 includes an elastic connecting ring 41 fixedly sleeved at the outer edge of the ring opening of the rubber sleeve 3, an inelastic pull rope 42 movably arranged in the elastic connecting ring 41, an inelastic fixing frame 43 fixedly mounted on the mounting frame 2 and connected to the outer side of the elastic connecting ring 41, and a reeling component 44 arranged on the inelastic fixing frame 43 for retracting and releasing the inelastic pull rope 42; the reeling component 44 includes a reeling roller 441 symmetrically arranged at the notch 45 and respectively fixedly connected to the two ends of the inelastic pull rope 42, and a reeling roller 442 respectively fixedly mounted at the notch 45 and respectively fixed to the two ends of the inelastic pull rope 42. A gear 442 is mounted on one end of the two winding rollers 441 and is meshed with the gear 442, and a motor 443 is fixedly connected to the side of the non-elastic fixing frame 43 and is connected to the elastic connecting ring 41 and is used to drive one of the winding rollers 441 to rotate. The ends of the two winding rollers 441 that are connected to the non-elastic pulling rope 42 are both rotatably connected to the non-elastic fixing frame 43. When the ring opening of the rubber sleeve 3 needs to be tightened, the motor 443 can be started to drive the winding roller 441 connected to it to rotate. At this time, the two gears 442 are fixedly connected to the side of the non-elastic fixing frame 43 and are connected to the non-elastic fixing frame 43. Under the meshing action, the other winding roller 441 will also rotate synchronously towards each other. Since the two winding rollers 441 are fixedly connected to the two ends of the inelastic pull rope 42 respectively, when the two winding rollers 441 rotate towards each other, the two ends of the inelastic pull rope 42 will be respectively wound onto the two winding rollers 441. When the two ends of the inelastic pull rope 42 are stretched and wound, it will synchronously drive the side of the elastic connecting ring 41 connected to the rubber sleeve 3 to close to each other, so that the ring opening of the rubber sleeve 3 can be contracted. When it is small enough to be tightly attached to the outer wall of the wire, the operation of the motor 443 can be suspended. When the ring of the rubber sleeve 3 needs to be loosened, the motor 443 can be operated in the direction to drive the two winding rollers 441 to rotate in the opposite direction. Then, the two winding rollers 441 will gradually loosen the wound inelastic pull rope 42. When the inelastic pull rope 42 is gradually loosened, the side where the elastic connecting ring 41 is connected to the inelastic fixed frame 43 will automatically restore the ring shape under the elastic action of the elastic connecting ring 41, thereby achieving the loosening of the ring of the rubber sleeve 3.

[0031] Among them, in order to facilitate the installation of the winding component 44 and the inelastic pull rope 42, a notch 45 is opened at the position of the elastic connecting ring 41 corresponding to the winding component 44, and both ends of the inelastic pull rope 42 pass through the elastic connecting ring 41 and are located at the notch 45; the design of the notch 45 can simplify the installation steps of the winding component 44 and the inelastic pull rope 42, thereby improving the convenience of installation.

[0032] Example 2

[0033] Different from the first embodiment, in order to facilitate the maintenance of the mounting frame 2 and the structure arranged on the mounting frame 2, locking bolts 22 are arranged on both sides of the mounting frame 2, and the mounting frame 2 is fixedly connected to the circuit breaker body 1 through the locking bolts 22; when the circuit breaker body 1 needs to be connected to the wire, the mounting frame 2 can be aligned with the position of the jack 11, and then the user only needs to simply rotate the locking bolts 22 to fix the mounting frame 2 and the rubber sleeve 3 and the closing structure 4 arranged on the mounting frame 2 on the circuit breaker body 1 for use. When the mounting frame 2 and the structure on the mounting frame 2 need to be maintained later, the user only needs to simply rotate the locking bolts 22 to remove the mounting frame 2 from the circuit breaker body 1, so that the mounting frame 2 and the structure arranged on the mounting frame 2 can be separately maintained, making it more convenient to use.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
