Description

Technical Field

[0001] The utility model relates to a visual transparent mask of a universal circuit breaker and belongs to the field of universal circuit breaker structure design. Background Art

[0002] A universal circuit breaker is a switching device that can connect, carry and disconnect current under normal circuit conditions, and can also connect, carry for a certain time and disconnect current under specified abnormal circuit conditions. Existing universal circuit breaker masks are usually made of non-transparent materials. When in use, such masks block the internal structure of the universal circuit breaker, so that the operation status of the internal mechanism cannot be directly observed from the outside. If the mask is made of transparent material, the user can see the operation status of the internal mechanism of the universal circuit breaker through the mask, but this will also result in some obvious defects, such as the status indicator (such as the opening and closing indicator / energy storage and release indicator) can be seen from multiple different directions, which is prone to misjudgment and poor user experience. Utility Model Content

[0003] The utility model provides a visual transparent mask of a universal circuit breaker to solve the problems pointed out in the background technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model provides a visual transparent mask for a universal circuit breaker, comprising a mask body, the mask body is made of transparent material, a status indication area is arranged on the front of the mask body, a perspective window is arranged within the range of the status indication area, and a sight shielding part is arranged on the mask body at the periphery of the status indication area.

[0006] In some embodiments, the outer surface of the status indication area is recessed to form an outer groove portion, and the side wall of the outer groove portion is expanded from the groove bottom to the outside of the groove to form the sight blocking portion.

[0007] In some embodiments, the inner side surface of the status indication area protrudes inward to form a protrusion, and an inner groove portion is provided on the inner surface of the protrusion at the perspective window, and the side wall of the inner groove portion is expanded from the bottom of the groove to the outside of the groove.

[0008] In some embodiments, inner and outer surfaces of the perspective window are plane.

[0009] In some embodiments, the sight blocking portion is a concave-convex texture or a frosted surface or an ink layer or a sticker layer or a film layer arranged around the status indication area.

[0010] In the universal frame circuit breaker mask provided by the utility model, a status indication area is provided on the front of the mask body, and a perspective window is provided within the range of the status indication area. When installed and used, the status indication area corresponds to the position of the status indicator board in the universal circuit breaker, so that the staff can view the circuit breaker status indicated by the status indicator board through the perspective window; since the mask body is transparent and has good perspective, in order to prevent the staff from making misjudgments when viewing the status indicator board, a sight shielding part is provided on the mask body; the sight shielding part plays a role in shielding the sight line around the status indication area, so that the staff can only see the status indicator board clearly through the perspective window.

[0016] 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.

[0017] This embodiment provides a visual transparent mask for a universal circuit breaker, the structure of which is as follows: Figures 1 to 3 As shown, it includes a mask body 1, which is made of a transparent material, such as a transparent PC material. During installation and use, the staff can observe the operation of the internal operating mechanism of the circuit breaker, the operation of the motor, the operation of the auxiliary contacts, etc. through the visualized transparent mask 1.

[0018] The front of the mask body 1 is provided with a status indication area 11, and a perspective window 13 is provided within the scope of the status indication area 11. When installed and used, the status indication area 11 corresponds to the position of the status indicator board in the universal circuit breaker, and the staff can view the circuit breaker status indicated by the status indicator board (such as the opening and closing indicator board / energy storage and release indicator board) through the perspective window 13; since the mask body 1 is transparent as a whole and has a certain perspective, in order to prevent the staff from making misjudgments when viewing the status indicator board, a sight blocking portion 12 is provided on the mask body 1 at the periphery of the status indication area 11; the sight blocking portion 12 serves to block the sight line around the status indication area 11, so that the staff can only see the status indicator board through the perspective window 13. Two perspective windows 13 are provided, corresponding to the opening and closing indicator board and the energy storage and release status indicator board respectively.

[0019] In one embodiment, if Figure 2 and Figure 3 As shown, the outer surface of the status indication area 11 is recessed to form an outer groove portion 14, and the side walls of the outer groove portion 14 are flared from the bottom of the groove to the outside of the groove to form the line of sight blocking portion 12. By setting the outer groove portion 14 and setting the side walls as a flared structure, the corresponding structure is increased and the permeability of the corresponding part is reduced; in order to enhance the line of sight blocking effect, further, in order to increase the line of sight blocking effect, the inner side surface of the status indication area 11 is provided to protrude inwardly to form a raised portion 15, and an inner groove portion 16 is provided on the inner surface of the raised portion 15 at the perspective window 13, and the side walls of the inner groove portion 16 are flared from the bottom of the groove to the outside of the groove, and the side walls of the inner groove portion 16 can play a certain shielding role, and the thickness of the perspective window 13 is relatively thin and the permeability is good.

[0020] In another embodiment, the sight blocking portion 12 is a concave-convex pattern arranged around the status indicating area 11, or the sight blocking portion 12 is set to be a frosted surface arranged around the status indicating area 11. Of course, the sight blocking portion 12 can also be set to an ink layer (such as a black ink layer) or a sticker layer or a film layer, and the sight blocking portion 12 is played by the setting of concave-convex pattern (such as mesh) / frosted surface / ink layer / sticker layer / film, etc.

[0021] In some embodiments, in order to further improve the transparency of the perspective window 13 and enhance the visual clarity of the area, the inner and outer surfaces of the perspective window 13 are set to be planes.

[0022] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
