[0001] The present application relates to the technical field of electrical components, and in particular to a direct current inductor box with a dustproof function. Background Art

[0002] The inductor is one of the important components of switching power supplies and power conversion equipment. The inductor is usually placed in an inductor box. The inductor box is responsible for placing the inductor, helping the inductor to dissipate heat, and enabling the inductor to work normally. Existing inductor boxes can usually be divided into two categories based on process materials: sheet metal splicing or aluminum die-casting.

[0003] However, the existing inductor box has the following defects: the connection between the inductor box and the device is generally installed through threaded fasteners, and the inductor box will scatter a lot of dust during long-term use. The dust may enter the inductor box from the installation of the threaded fasteners or the gap between the other inductor box and the device, affecting the normal operation of the device. Summary of the invention

[0004] One object of the present application is to provide a DC inductor box with good dustproof sealing effect and convenient installation and dustproof function.

[0005] To achieve the above objectives, the technical solution adopted in the present application is: a DC inductor box with a dustproof function, comprising a shell, one side of the shell being a mounting surface, a cavity and a mounting hole being provided on the mounting surface, a first seal being provided around the mounting surface, the mounting hole and the first seal being provided circumferentially around the cavity, the first seal being located on a side of the mounting hole away from the cavity, a second seal being provided on the mounting hole, at least a portion of the second seal extending toward one side of the first seal, a coupling groove being provided on the first seal, and when the mounting surface is attached to the surface of an object, the second seal is suitable for being deformed and embedded in the coupling groove, so that both the first seal and the second seal contact the surface of the object.

[0006] In some embodiments, a plane where the top of the second sealing member is located is higher than a plane where the top of the first sealing member is located.

[0007] In some embodiments, the main body of the second sealing member is in the shape of a trumpet-shaped structure with its opening facing upward.

[0008] In some embodiments, at least one reinforcing rib is disposed on the outer side of the second sealing member.

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0025] The present application is further described below with reference to the accompanying drawings:

[0026] like Figures 1 to 4 As shown, the present application provides a DC inductor box with dustproof function, including a shell 1, one side of the shell 1 is a mounting surface 11, the mounting surface 11 is suitable for being attached to the surface of an object, and a cavity 111 and a mounting hole 112 are provided on the mounting surface 11, the cavity 111 is suitable for accommodating the inductor, and the mounting hole 112 is used to fix the shell 1 to the surface of the object.

[0027] It is worth noting that the mounting surface 11 is usually set to be a plane, and the surface of the object to which the mounting surface 11 is attached is also correspondingly a plane, ensuring that the mounting surface 11 and the surface of the object can fit as closely as possible.

[0028] The first sealing member 2 is arranged around the mounting surface 11, and the mounting hole 112 and the first sealing member 2 are arranged circumferentially around the cavity 111. The housing 1 can be fixed to the surface of an object or equipment through the mounting hole 112. The first sealing member 2 is located on the side of the mounting hole 112 away from the cavity 111. The first sealing member 2 can play a sealing role, isolating the outside world from the cavity 111, and reducing the probability of external dust entering the cavity 111.

[0029] A second seal 3 is provided on the mounting hole 112. The second seal 3 can be used to isolate the mounting hole 112 from the cavity 111, reducing the probability of external dust entering the cavity 111 from the mounting hole 112. At least part of the second seal 3 extends to one side of the first seal 2 and limits the first seal 2 from being away from the mounting hole 112. The second seal 3 can also play a limiting and fixing role, helping the first seal 2 to be fixed on the mounting surface 11, so that the shell 1 does not need to be positioned for the first seal 2 during installation, which can reduce the difficulty of installing the shell 1.

[0030] In some embodiments, an auxiliary fixing tool such as an adhesive may be provided between the first seal 2 and the mounting surface 11 to help position and fix the first seal 2 and reduce the probability of deformation and slippage of the first seal 2.

[0031] In some embodiments, the second sealing member 3 is preferably made of a flexible rubber material, which is easy to shape and can provide a better dustproof sealing effect.

[0032] like Figures 2 to 3 In the illustrated embodiment, a coupling groove 21 is provided on the first seal 2. When the mounting surface 11 is attached to the surface of an object, the second seal 3 is adapted to be deformed and fitted into the coupling groove 21, so that both the first seal 2 and the second seal 3 contact the surface of the object. The deformation and fitting of the first seal 2 and the second seal 3 can reduce space occupancy and achieve synchronous sealing in a smaller space. At the same time, the sealing effect can be improved, and the mounting hole 112 can be better dust-proof sealed.

[0033] like Figures 2 to 3 In the illustrated embodiment, the plane where the top of the second seal 3 is located is higher than the plane where the top of the first seal 2 is located, ensuring that the second seal 3 can contact the surface of the object before the first seal 2, so that it can be deformed by the pressure of the object surface and fit into the coupling groove 21.

[0034] like Figures 2 to 3 In the illustrated embodiment, the main body of the second seal 3 is a trumpet-shaped structure with its opening facing upward. The second seal 3 designed in this way can not only obtain an all-round dustproof sealing effect on the mounting hole 112, but also guide and help the threaded fastener to enter the mounting hole 112.

[0035] In some embodiments, at least one reinforcing rib 31 is disposed on the outer side of the second sealing member 3 , and the reinforcing rib 31 is used to improve the fit between the second sealing member 3 and the surface of the object after deformation, thereby further improving the sealing performance.

[0036] In some embodiments, there are multiple reinforcing ribs 31 , and the reinforcing ribs 31 are arranged circumferentially along the second sealing member 3 to ensure that the second sealing member 3 can fit the surface of the object as fully as possible after deformation.

[0037] like Figure 4 In the illustrated embodiment, the reinforcing ribs 31 are evenly arranged on the side of the second seal 3 away from the first seal 2. Since the side of the second seal 3 close to the first seal 2 can be supported and fitted by engaging with the coupling groove 21, and there is no corresponding support on the side of the second seal 3 away from the first seal 2, the reinforcing ribs 31 are arranged on the side of the second seal 3 away from the first seal 2 to improve the fit between this side and the surface of the object, thereby improving the dustproof sealing performance.

[0038] like Figures 2 to 3 In the illustrated embodiment, the mounting hole 112 protrudes from the mounting surface 11 , and the first sealing member 2 is interference-fittedly arranged on the side of the mounting hole 112 away from the cavity 111 . The mounting hole 112 can be used to clamp and fix the first sealing member 2, thereby reducing the probability of movement of the first sealing member 2 .

[0039] In some embodiments, the first seal 2 is preferably made of a flexible rubber material. The rubber material is flexible and can provide a better sealing and dustproof effect. By utilizing the deformation generated by the rubber material, the first seal 2 can be mounted on all mounting holes 112 away from the side of the cavity 111, thereby achieving a certain fixing effect. At the same time, with the help of the second seal 3, the positional relationship between the seal and the mounting hole 112 is maintained, and it is not easy to separate from the mounting hole 112, thereby reducing the difficulty of installation.

[0040] like Figures 2 to 3 In the illustrated embodiment, blocking edges 113 are provided around the mounting surface 11, and the first seal 2 is adapted to be embedded between the blocking edge 113 and the mounting hole 112 at the mounting hole 112. The blocking edge 113 can protect the first seal 2 and reduce the probability of damage to the first seal 2 and the speed of aging.

[0041] like Figures 2 to 3 In the illustrated embodiment, the plane where the top of the blocking edge 113 is located is not lower than the plane where the top of the mounting hole 112 is located, ensuring that the blocking edge 113 can completely cover and protect the mounting hole 112 .

[0042] like Figures 2 to 3In the illustrated embodiment, the plane where the top of the first sealing member 2 is located is not lower than the plane where the top of the blocking edge 113 is located, ensuring that the first sealing member 2 can be squeezed and fitted with the surface of the object, thereby obtaining sufficient sealing.

[0043] In some embodiments, the housing 1 is provided with heat dissipation fins 12 on at least one side other than the mounting surface 11 , so as to help the cavity 111 to dissipate heat passively.

[0044] like Figure 1 In the illustrated embodiment, due to the presence of the mounting hole 112, the area of ​​the mounting surface 11 is larger than the cross-section of the cavity 111, and the housing 1 is provided with a plurality of heat dissipation fins 12 on adjacent sides of the mounting surface 11, i.e., around the cavity 111, so as to make full use of the space around the cavity 111 left due to the excessively large area of ​​the mounting surface 11, thereby improving the heat dissipation efficiency.

[0045] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
