DETAILED DESCRIPTION

[0022] 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.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0025] like Figures 1 to 4 As shown, this embodiment provides a universal circuit breaker mask, including a mask body 1, the mask body 1 is provided with a through mounting hole 11, the mounting hole 11 is provided with a pointer-type measuring instrument 2, the pointer-type measuring instrument 2 has a header 21 exposed outside the mask body 1, and the pointer-type measuring instrument 2 is used to measure temperature or humidity or temperature and humidity. The through mounting hole 11 is provided on the mask body 1, and the pointer-type measuring instrument 2 is installed through the mounting hole 11, which expands the function of the universal circuit breaker mask. When installed and used, the pointer-type measuring instrument 2 can measure the temperature and humidity inside the universal circuit breaker in real time, and display it through the pointer of the header 21, so that the staff can know it conveniently and take necessary measures in time when problems occur. The pointer-type measuring instrument 2 described in this embodiment can be directly purchased from the market, and its structure is not described in detail here.

[0026] As a further improvement, Figure 1 As shown, the inner side of the mask body 1 is provided with a temperature measuring area 12, and the temperature measuring area 12 is provided with a thermochromic material layer. In this embodiment, at least the temperature measuring area 12 is made of a transparent material so that the thermochromic material layer can be seen from the outside. By setting the thermochromic material layer, when the internal temperature of the universal circuit breaker changes in actual use, the color of the thermochromic material layer changes, so that the staff can judge the internal temperature of the universal circuit breaker by observing the color of the thermochromic material layer; thus, a more accurate judgment can be made in combination with the pointer measuring instrument 2. For example, the thermochromic material layer can use commercially available thermochromic ink.

[0027] In some embodiments, the mask body 1 is made of a transparent material as a whole, such as a transparent PC material. In this way, 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 transparent mask 1.

[0028] Furthermore, a secondary wiring mark 13 is provided on the inner side surface of the upper front part of the mask body 1. The staff can refer to the secondary wiring mark 13 when connecting the wires to prevent wrong connection. In this embodiment, the secondary wiring mark 13 is set to a convex rib structure, and the convex rib structure is integrally formed on the inner side surface of the mask body 1, which is convenient for processing and will not cause the secondary wiring mark 13 to fall off; the convex rib structure increases the thickness of the corresponding part on the mask body 1, and the clarity is good; as a variation, the secondary wiring mark 13 can also be set to a concave rib structure.

[0029] In some embodiments, Figure 1 , Figure 3 and Figure 4 As shown, a status indication area 14 is provided on the front of the mask body 1, and a perspective window 16 is provided within the range of the status indication area 14. When the mask is installed and used, the status indication area 14 corresponds to the position of the status indicator board (such as the opening and closing indicator board / energy storage and release status indicator board) in the universal circuit breaker, and the staff reads the status indicator board information through the perspective window 16 to know the corresponding state of the circuit breaker; since the mask body 1 is set to be transparent as a whole, the mask body 1 has a certain perspective, and in order to prevent the staff from making misjudgments when viewing the status indicator board, a sight blocking structure 15 is provided on the mask body 1 at the periphery of the status indication area 14; the sight blocking structure 15 has a certain effect of blocking the sight around the status indication area 14, so that the staff can only see the status indicator board through the perspective window 16; two perspective windows 16 are provided, corresponding to the opening and closing indicator board and the energy storage and release status indicator board respectively.

[0030] For example, see Figure 3 and Figure 4As shown, the outer side surface of the status indication area 14 is recessed to form a first groove portion 17, and the side walls of the first groove portion 17 are expanded from the bottom of the groove to the outside of the groove to form the line of sight blocking structure 15. By setting the first groove portion 17 and setting the side walls as the expanded structure, the corresponding structure is increased, the permeability of the corresponding part is reduced, and the line of sight blocking effect is achieved; by the same token, further, in order to increase the line of sight blocking effect around the perspective window 16, the inner side surface of the status indication area 14 is set to protrude inward to form a raised portion 18, and a second groove portion 19 is formed on the inner surface of the raised portion 18 at the perspective window 16, and the side walls of the second groove portion 19 are expanded from the bottom of the groove to the outside of the groove, and the side walls of the second groove portion 19 can play a certain blocking role, and the thickness of the perspective window 16 is thinner and the permeability is better.

[0031] As another implementation scheme of the line of sight blocking structure 15, the line of sight blocking structure 15 is a concave-convex pattern arranged on the periphery of the status indication area 14, or the line of sight blocking structure 15 is a frosted surface arranged on the periphery of the status indication area 14, or the line of sight blocking structure 15 is an ink layer (such as black ink) arranged around the status indication area 14, and the line of sight is blocked by setting a concave-convex pattern (such as a grid) or a frosted surface or an ink or sticker layer.

[0032] In some embodiments, in order to improve the transparency of the perspective window 16 and enhance the visual clarity of the area, the inner and outer surfaces of the perspective window 16 are set to be planes.

[0033] In some embodiments, the pointer-type measuring instrument 2 is a columnar structure, and a buckle is provided on its side wall for engaging with the edge of the mounting hole 11, that is, when the pointer-type measuring instrument 2 is installed, it is inserted into the mounting hole 11, and the buckle is engaged with the edge of the mounting hole 11 to achieve quick installation.

[0034] As an implementation scheme of a pointer-type measuring instrument, the pointer-type measuring instrument 2 adopts a cylindrical structure, an external thread is arranged on its outer peripheral wall, and a locking nut is screwed on. During installation, the pointer-type measuring instrument 2 is inserted into the mounting hole 11 outwardly and inwardly, and then the locking nut is screwed onto the pointer-type measuring instrument 2 from the inner side of the mask body 1, thereby fixing the pointer-type measuring instrument.

[0035] 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.
