AI Technical Summary
Technical Problem
The existing electrical box front cover has a simple design, resulting in insufficient overall strength and affecting the assembly effect of the electrical box.
Method used
The box cover design features curved surfaces on the first and second sides with a smooth transition. The curved surface on the second side evenly distributes stress, reduces stress concentration, and enhances resistance to deformation and load-bearing capacity.
Benefits of technology
The overall strength of the electrical box has been improved, its bending and compressive strength has been enhanced, the possibility of local deformation and cracking has been reduced, and the sealing effect and appearance recognition have been improved.

Abstract
The application relates to an electrical box, and belongs to the technical field of electrical equipment. The electrical box comprises a box body, a box cover, the box cover is arranged on the box body, the box cover comprises a first surface and a second surface which is arranged around the first surface and is connected with the first surface, at least part of the first surface is a curved surface, the first surface and the second surface are arranged on the side of the box cover which is away from the box body, the second surface is a curved surface and is smoothly connected with the first surface, the second surface is a curved surface and is smoothly connected with the first surface in the application, stress can be uniformly dispersed, stress concentration can be reduced, external load can be transmitted to the whole box cover, a high stress area is prevented from being formed at a certain point, and the anti-deformation performance and the load-carrying performance of the box cover are improved, so that the strength of the whole electrical box is improved after the box cover is combined with the box body.
