Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1 and 2, the present embodiment provides an electric distribution box including a cover 10, a housing 20, and a back plate 30. The cover 10 is hinged to the housing 20, the cover 10 can cover one side of the housing 20, the housing 20 is sleeved on the back plate 30, the back plate 30 is provided with a fixing portion 32, and the back plate 30 is mounted on a wall through the fixing portion 32.

First embodiment

Specifically, in the present embodiment, as shown in fig. 2 to 5, the fixing portions 21 are respectively fixedly installed at four corner portions of one side of the back plate 30, the fixing portions 21 can be inserted into holes pre-opened on the wall so as to install the back plate 30 on the wall, the extending portion 31 extends upward from the edge of the back plate 30, the extending portion 31 is located at the other side of the back plate 30, preferably, a groove 311 is provided on the extending portion 31, and the rubber strip 40 is provided in the groove 311.

In the present embodiment, as shown in fig. 6 to 8, the housing 20 is sleeved outside the extension portion 31, and the bottom wall portion of the housing 20 is provided with a threading hole 21 for gathering the wire harness. In addition, because the rubber strip 40 is arranged on the extension portion 31, after the housing 20 is sleeved on the extension portion 31, the rubber strip 40 is also compressed between the housing 20 and the extension portion 31, so that the rubber strip 40 plays a role in sealing, and meanwhile, the connection tightness between the back plate 30 and the housing 20 is also enhanced.

The specific use method of the embodiment is as follows: firstly, arranging four holes at corresponding positions of a wall body; then, the fixing portion 32 of the back plate 30 is inserted into the hole, thereby mounting the back plate 30 on the wall; next, the relevant electrical components are mounted on the back plate 30; finally, the housing 20 is assembled to the back plate 30, completing the assembly of the entire electrical box.
