DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1-2 As shown, a position judgment structure for the handle 2 of a 5G1U circuit breaker in an embodiment of the present utility model includes a circuit breaker body 1, and the circuit breaker body 1 includes a first housing 10 and a second housing 11 that are spliced together. The first housing 10 and the second housing 11 are spliced to form an activity interval 12 for accommodating the handle 2. A through port 20 communicating with the activity interval 12 is formed on the left side of the circuit breaker body 1. The handle 2 is movably arranged in the through port 20, and the inner end of the handle 2 extends into the activity interval 12 to control the opening and closing of the circuit breaker body 1. A signal element 3 is arranged at the corresponding position of the handle 2 in the activity interval 12.

[0022] During use, the opening and closing of the circuit breaker body 1 are controlled by pressing or pulling out the handle 2. A signal element 3 is arranged at the corresponding position of the handle 2 in the activity interval 12. The signal element 3 and the handle 2 cooperate to output an external signal, transmitting the working state of the circuit breaker. The staff can remotely manage multiple circuit breakers through a signal receiver, effectively improving the use convenience and flexibility of the product.

[0023] The signal element 3 is a micro switch, and the micro switch is electrically connected to a circuit board 30 inside the circuit breaker body 1; the right insertion end of the circuit breaker body 1 has a first electrode interface 31, a second electrode interface 32, and a signal terminal interface 33, and the signal terminal interface 33 is electrically connected to the circuit board 30.

[0024] During use, the micro switch is electrically connected to the circuit board 30 inside the circuit breaker body 1. The insertion end of the circuit breaker has a terminal interface electrically connected to the circuit board 30. When the circuit breaker body 1 is in the inserted state, the terminal interface is connected to an external signal unit to output an external signal.

[0025] The handle 2 includes an operation part 21 for driving the opening and closing, a contact part 22 cooperating with the signal element 3, and a driving part 23; a fitting groove 24 is formed in the driving part 23, and a driving rod 25 is movably connected in the fitting groove 24. The driving rod 25 is drivingly connected to the opening and closing mechanism inside the circuit breaker body 1.

[0026] In use, the opening and closing of the handle 2 is driven by the operation part 21. The handle 2 is drivingly connected to the opening and closing mechanism inside the circuit breaker body 1 through the driving rod 25. When the handle 2 is opened and closed, the microswitch is pressed by the contact part 22, so that the microswitch is turned on or off, thereby outputting the opening and closing signal externally and transmitting the working state of the circuit breaker;

[0027] The connection and driving mode of the driving part 23 to the opening and closing mechanism belong to the prior art and will not be elaborated here.

[0028] A cavity 4 is formed inside the handle 2, and an indicating window 40 communicating with the cavity 4 is opened outside. An indicating ornament 41 is movably arranged in the cavity 4, and an indicating plate 42 is formed at the position corresponding to the indicating window 40 on the indicating ornament 41; the indicating ornament 41 has a pivot part 43 rotatably matched with the handle 2 and a matching part 44 for driving its swing. A matching block 45 is formed at the bottom inside the moving interval 12 corresponding to the matching part 44.

[0029] In use, when the handle 2 is pressed inward, the indicating ornament 41 is driven to move. The indicating ornament 41 rotates around the pivot part 43 through the cooperation between the cooperation part 44 and the cooperation block 45. Specifically, the cooperation block 45 is provided with an inclined waist. When the cooperation part 44 contacts the cooperation block 45, the indicating ornament 41 is guided to rotate around the pivot by the inclined waist. The rotation of the indicating part drives the indicating plate 42 to swing and switch the indicating state, that is, one of the indicating marks corresponds to the indicating window 40. The staff can know the current opening and closing state of the device by observing the indicating mark displayed in the indicating window 40, which is convenient for the daily management and operation of the circuit breaker; when the handle 2 is pulled outward, the indicating ornament 41 swings back and switches to another indicating state.

[0030] At the same time, it should be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the protection scope of the present invention.

[0031] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
