[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs. The terms used in this specification in the description of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0029] The present application provides an electrical device, and the electrical device includes a power distribution device 1000. Among them, the electrical device is used to supply power to other electrical devices.

[0030] For the aforementioned power distribution device 1000, please refer to Figure 1And Figure 2 The power distribution device 1000 includes a housing 100, a first power distribution module 200, a second power distribution module 300, and a plug module 400.

[0031] In some embodiments, the housing 100 is provided with a receiving cavity 110.

[0032] In some embodiments, the first power distribution module 200 is received in the receiving cavity 110. The first power distribution module 200 includes a first switch 210 and a first socket 220. The first switch 210 and the first socket 220 are at least partially exposed on the surface of the housing 100, and the first switch 210 and the first socket 220 are connected in series.

[0033] In some embodiments, the second power distribution module 300 is received in the receiving cavity 110. The second power distribution module 300 includes a second switch 310 and a second socket 320. The second switch 310 and the second socket 320 are at least partially exposed on the surface of the housing 100, and the second switch 310 and the second socket 320 are connected in series.

[0034] In some embodiments, the plug module 400 is received in the receiving cavity 110. The first power distribution module 200 and the second power distribution module 300 are respectively connected to the plug module 400. The plug module 400 is further provided with a neutral line, and the first power distribution module 200 and the second power distribution module 300 are both connected in parallel to the neutral line.

[0035] With the above structure, the first switch 210 independently controls the first socket 220, the second switch 310 independently controls the second socket 320, and both are electrically connected to the same plug module 400, so that it is not necessary to cut off all the power supplies, improving the work efficiency.

[0036] And the above housing 100 serves as the installation base of the power distribution device 1000. Please refer to Figures 1 to 3 , which includes a bottom case 120 and an upper cover 130.

[0037] In some embodiments, the upper cover 130 is buckled on the bottom case 120, and the upper cover 130 and the bottom case 120 together enclose the receiving cavity 110. The first switch 210, the first socket 220, the second switch 310, and the second socket 320 are sequentially installed on the upper cover 130 along a preset direction F. Through the buckled upper cover 130 and bottom case 120, the internal structure is protected. Among them, the bottom case 120 is arranged in a cuboid shape, and the preset direction F is the extending direction of the longest edge of the bottom case 120, so that the above first switch 210, first socket 220, second switch 310, and second socket 320 can be arranged along the preset direction F, facilitating the arrangement and electrical connection of other electrical devices. The first switch 210 controls the first socket 220, and the first socket 220 can be electrically connected to an electrical device; the second switch 310 controls the second socket 320, and the second socket 320 can be electrically connected to an electrical device.

[0038] It should still be noted that the first socket 220 is provided with a first live wire, and the first live wire is electrically connected to the plug module 400 through the first switch 210; the second socket 320 is provided with a second live wire, and the second live wire is electrically connected to the plug module 400 through the second switch 310. It can be understood that since the two are connected to the same plug module 400, the voltages between the first socket 220 and the second socket 320 are equal, so as to facilitate the unified management of the voltages of electrical equipment.

[0039] Regarding the above-mentioned bottom case 120 and upper cover 130, it should still be noted that the cross-sectional area of the bottom case 120 perpendicular to the preset direction F is not a regular square frame, but is recessed towards the receiving cavity 110 on the side away from the bottom of the bottom case 120, so that when the upper cover 130 is buckled on the bottom case 120, its side is set as a straight edge. Thereby reducing the protruding distance of the upper cover 130 relative to the bottom case 120, and thus making the outer surface of the housing 100 flat, so as to facilitate installation and fixation as well as aesthetics. Optionally, the bottom case 120 and the upper cover 130 can be in the form of snap connection, screw connection, etc. Here, welding or integral molding is not adopted mainly to facilitate the separation of the upper cover 130 from the bottom case 120, so as to facilitate the repair of other internal parts.

[0040] In some embodiments, please refer to Figure 2 , the power distribution device 1000 further includes an insulating member 700. The insulating member 700 is attached to the bottom case 120 and / or the upper cover 130.

[0042] In some embodiments, the mounting member 140 is mounted on the side of the bottom case 120 facing away from the upper cover 130, and the mounting member 140 is used to mount the power distribution device 1000 on a cabinet or other external structure. It can be understood that the mounting member 140 only needs to mount the power distribution device 1000 on other cabinets or external structures. In some preferred embodiments, the mounting member 140 can be a spring washer, so as to facilitate snap connection or buckling on a cabinet or other external structure; in some other embodiments, the mounting member 140 can also be a bolt, a magnetic attracting member, or a structure that cooperates with other structures for fixation, which will not be elaborated here one by one. Since the housing 100 composed of the above-mentioned bottom case 120 and upper cover 130 is a cuboid, the number of the mounting members 140 can be multiple, so as to improve the installation stability of the power distribution device. In some embodiments, the number of the mounting members 140 can be two, three, four, etc., and their distribution forms can be equally spaced, or changed according to the actual situation and specific installation environment.

In the embodiment of the present application, the number of openings in the first opening group 131 is three, and the number of the first sockets 220 is two groups. Among them, the first switch 210, one group of the first sockets 220, and the other group of the first sockets 220 are respectively arranged in the openings of the three first opening groups 131. The thickness of the portion of the first clamping portion 221 close to the opening of the first opening group 131 is greater than the thickness of the portion of the first clamping portion 221 away from the opening of the first opening group 131, so that when the first socket 220 is inserted into the opening of the first opening group 131, it can be gradually inserted and clamped to the opening. And the thickness of the portion of the second clamping portion 211 close to the opening of the first opening group 131 is greater than the thickness of the portion of the second clamping portion 211 away from the opening of the second opening group 132, so that when the first switch 210 is inserted into the opening of the first opening group 131, it can be gradually inserted and clamped to the opening.

And the thickness of the part of the fourth clamping portion 311 close to the opening of the second opening group 132 is greater than the thickness of the part of the fourth clamping portion 311 away from the opening of the second opening group 132, so that when the second switch 310 is inserted into the opening of the second opening group 132, it can be gradually inserted and clamped into the opening.
