The power distribution cabinet is usually used in the occasions with dispersed loads and less loops; the power provided by a certain circuit of the upper-level power distribution equipment is distributed to the nearby loads. This level of equipment should provide protection, monitoring and control of the load.

The switch board has certain installation requirement, specifically is switch board application incombustible material preparation. An open-type power distribution cabinet can be installed in places with small electric shock danger or offices; however, in places such as processing workshops, castings, forgings, heat treatments, boiler rooms, etc. where the risk of electric shock is high or the working environment is poor, closed cabinets should be installed. Of course, in other dangerous work places where, for example, conductive dust exists or flammable and explosive gas is generated, explosion-proof type electric equipment must be installed.

Taking a closed power distribution cabinet as an example, after the electric elements in the power distribution cabinet are installed, a sealing plate must be used for sealing the power distribution cabinet; of course, the power distribution cabinets have front opening doors, and the closing plate can be referred to as a rear closing plate. Can avoid the inside electric elements of switch board to expose like this, avoid electrocuteeing danger, improve safety in utilization.

The vertical channel length of present switch board is 1800mm usually, but in some non-standard design's switch board, vertical channel length also has 1600mm, 1400mm or 1200 mm's switch board, and the back shrouding that needs to produce different specifications like this is installed on the switch board, leads to production specification to be non-uniform, and manufacturing cost is higher.

Therefore, the rear sealing plate is designed into a standardized module with the thickness of 200mm, so that the production specification is unified, and the production cost is reduced. However, in the actual installation process, as the length of the vertical channel of the cabinet body of the power distribution cabinet is longer (1200-1800 mm), the installation of the rear sealing plate needs to be carried out for 6 times at most, and the installation time reaches 9 times in most cases; the installation times are many, and a large amount of installation time and labor cost are consumed. And the rear sealing plates and the cabinet body are installed and connected through screws, and the number of the screws is at least 24 according to the calculation of 4 installation screws of each rear sealing plate, so that the installation time is further consumed.

Therefore, the power distribution cabinet provided by the embodiment of the application has the main idea that the cabinet body of the power distribution cabinet is provided with the first mounting structure, the sealing plate is provided with the second mounting structure, and the sealing plate is hung on the first mounting structure through the second mounting structure. Like this, when the installation shrouding, directly with the shrouding articulate on the cabinet body can, improved the installation effectiveness of shrouding, saved installation time.

Referring to fig. 1, fig. 1 is a schematic view of an overall structure of a power distribution cabinet provided in an embodiment of the present application. The embodiment of the application provides a switch board includes: the cabinet 10 comprises a cabinet body 10, wherein an opening 11 is formed in one side of the cabinet body 10, a first mounting structure 12 is arranged on the cabinet body 10, and the first mounting structure 12 is adjacent to the opening 11.

Specifically, in the embodiment of the present application, the cabinet 10 may be the same cabinet as a power distribution cabinet in the related art, for example, the cabinet may be made of a non-flammable material. Since the switch cabinet usually has a front opening door, the opening 11 may particularly be an opening on the side opposite to the front opening door.

Alternatively, the first mounting structure 12 may be a post structure, a hook structure, a snap structure, or other structure capable of providing a point of support.

The switch board that this application embodiment provided still includes: at least one closure plate 20, the closure plate 20 having second mounting structure 21 thereon. The closure plate 20 closes the opening 11 when the second mounting structure 21 is hung from the first mounting structure 12. Like this, can improve the installation effectiveness of shrouding, save installation time to the installation effectiveness of whole switch board installation has been improved.

As the vertical channel length of the switch cabinet may have different lengths, for example 1800mm, 1600mm or 1200 mm; accordingly, the size of the cover plate 20 in the embodiment of the present application may also correspond to different length dimensions. The width of the sealing plate 20 is substantially the same as or identical to the width of the opening 11.

Optionally, because the shrouding 20 of the not unidimensional needs of adaptation different switch boards needs production, can increase shrouding 20's the production degree of difficulty and cost like this. Thus, in the embodiment of the present application, the length dimension of the cover plate 20 is designed to be 200mm, 400mm or 600mm standardized modules, respectively. For example, in some production batches all production is on the 200mm scale, while in other production batches all production is on the 400mm or 600mm scale. The opening 11 is then closed by splicing of different standardized module closure plates 20 (e.g. 2x600mm +400mm, for a vertical channel length of 1600 mm). Thus simplifying the production flow of the sealing plate 20 and saving the production cost; moreover, when the sealing plate 20 is installed, the number of the sealing plates 20 to be installed is reduced, and only three sealing plates 20 are needed to be installed at most, so that the installation efficiency of the sealing plates 20 is improved.

Alternatively, referring to fig. 2, the first mounting structure 12 may be a hook 121, and the hook 121 extends outward from the edge of the opening 11 (for example, as shown in fig. 2, it may extend in a direction close to the closing plate 20).

Wherein, the hook 121 can be fixedly connected to the cabinet 10. For example, in some possible ways, the hook 121 may be a hook that is reserved on the cabinet 10 when the cabinet 10 is produced, i.e., the hook 121 and the cabinet 10 may be integrally formed. In other possible ways, the hook 121 may be detachably connected to the cabinet 10. For example, mounting screw holes may be reserved when the cabinet 10 is produced, and one end of the hook 121 facing away from the sealing plate 20 may be threaded, so that the hook 121 may be screwed onto the cabinet 10. It is understood that the hook 121 may be disposed on the cabinet 10 by clipping.

The second mounting structure 21 may be a mounting buckle 211. Specifically, the mounting fasteners 211 may be through holes extending through two opposing surfaces of the cover plate 20. Thus, the through-hole can be directly hung on the hook 121.

Wherein, the cross section of the mounting buckle 211 can be round, gourd-shaped, semicircular, oval or runway type. This can facilitate the installation of shrouding 20 and connect, especially under the condition that needs a plurality of shrouding of installation, can improve the installation effectiveness.

In some possible ways, referring to fig. 3-5, fig. 3 is a partial enlarged view at a in fig. 2, fig. 4 is a left side view of fig. 2, and fig. 5 is a partial enlarged view at B in fig. 4. In the embodiment of the present application, the hook 121 is L-shaped, and a side of the vertical section of the hook 121 facing the opening 11 has a slope 1211, and the slope 1211 extends from the top end to the bottom end of the hook 121.

The slope 1211 may be integrally formed on the hook 121 by chamfering; in some possible designs, the sloped surface 1211 may be formed by cutting after the hook 1211 is formed.

In the embodiment of the present application, the slope 1211 is provided at the vertical section of the hook 121. Therefore, after the sealing plate 20 is hung on the hook 121, the sealing plate 20 can slide downwards along the slope 1211 under the action of self gravity, so that the sealing plate 20 can be tightly attached to the cabinet 10, and the situation of looseness or shaking is avoided.

Further, the number of the hooks 121 is at least four, and the four hooks 121 are arranged at the edge of the opening 11 in a matrix. For example, when the size of the sealing plate 20 is produced according to the size of a power distribution cabinet (the length of the sealing plate 20 is substantially the same as or approximately the same as the length of the vertical channel of the power distribution cabinet), the sealing plate 20 can be hooked by four hooks 121. Need not install shrouding 20 through self-tapping screw like this, improved shrouding 20's installation effectiveness to, fix shrouding 20 through four couples 121, make shrouding 20 can be by stable fixing on the cabinet body 10, improved the stability after shrouding 20 installs.

It will be appreciated that where the opening 11 is closed by a standard modular closure plate 20, the number of hooks 121 may be four hooks 121 per closure plate 20. In this way, each sealing plate 20 can be stably fixed to the cabinet 10.

Optionally, as shown in fig. 6 to 8, fig. 6 is an exploded structural schematic view of a power distribution cabinet provided in another embodiment of the present application, fig. 7 is a partially enlarged view at C in fig. 6, and fig. 8 is a structural schematic view of a buckle in the power distribution cabinet provided in the embodiment of the present application. In the embodiment of the present application, the first mounting structure 12 may be a mounting through hole 122. Wherein, the mounting through hole 122 may be a tapping screw hole on the cabinet 10.

Specifically, referring to fig. 6, the opening of the cabinet 10 has a curled edge, and a tapping screw hole may be formed in the curled edge.

The second mounting structure 21 may be a snap 212 affixed to the cover plate 20. Specifically, clasp 212 may be integrally formed on plate 20, such as a protrusion from a surface of plate 20. In some possible ways, the clip 212 may also be a plastic screw embedded into an original self-tapping screw hole of the sealing plate 20, so that the clip 212 can be quickly fixed on the sealing plate 20 without changing the original structure of the sealing plate 20.

Specifically, the snap 212 is inserted into the mounting through hole 122 when the cover plate 20 is mounted on the cabinet 10.

Thus, the sealing plate 20 can be quickly installed on the cabinet body 10 without changing the original structure of the cabinet body 10, and the production cost of the cabinet body 10 is saved.

Further, referring to FIG. 8, the clip 212 includes a connecting end 2121 and a clip end 2122, and the connecting end 2121 is connected to the cover plate 20. Specifically, the connecting end 2121 may be clamped to the sealing plate 20, or may be welded to the sealing plate 20 by electric welding or the like.

The clip end 2122 has a resilient clip arm 2122 a. The elastic clip arm 2122a may be one, or may be a plurality of elastic clip arms encircling the periphery of the clip end 2122. The plurality of elastic clip arms 2122a and the clip end 2122 may be integrally formed, so as to ensure that the elastic clip arms 2122a have sufficient elastic restoring force and strength.

It will be appreciated that when the clip 212 is inserted into the mounting through hole 122, the resilient clip arms 2122a abut against the inner side walls of the opening 11. Specifically, referring to fig. 6, the elastic clip arm 2122a may abut against an inner sidewall of the curl.

In this way, the elastic clip arm 2122a abuts against the inner side wall of the opening 11, so that the close installation of the sealing plate 20 and the cabinet 10 is ensured, and the loosening is avoided.

It should be further noted that, since various electrical components are usually disposed in the power distribution cabinet, when a current flows through the electrical components, the electrical components have certain resistance; that is, the electrical components themselves generate a certain amount of heat. The power distribution cabinet is used for protecting the electrical elements and also needs to be capable of timely evacuating heat generated by the electrical elements.

Thus, referring to fig. 9, fig. 9 is a front view of fig. 6. In the embodiment of the present application, the sealing plate 20 has a plurality of heat dissipating through holes 22 thereon, and the plurality of heat dissipating through holes 22 are arranged in a matrix on the sealing plate 20. In this way, by arranging the plurality of heat dissipation through holes 22, heat generated by the electric elements in the power distribution cabinet can be timely evacuated, and danger is avoided; meanwhile, the plurality of heat dissipation through holes 22 are arranged on the sealing plate 20 in a matrix manner, so that the standardized production of the sealing plate 20 is facilitated, and the attractiveness of the sealing plate 20 is ensured.

Optionally, the width L of the heat dissipation through holes 22 is 5-10 mm, the length D1 is 20-30 mm, and the distance D2 between adjacent heat dissipation through holes 22 is 15-25 mm. Therefore, the sealing plate 20 is guaranteed to have enough heat dissipation area, and meanwhile, the overall strength of the sealing plate 20 can be guaranteed.

In one implementation, the cross-section of the heat dissipating through-holes 22 is rectangular, oval, or racetrack.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
