Detailed Description of the Embodiments

A clear and complete description of the technical solutions of the present invention will be given below in combination with the accompanying drawings and specific embodiments.

Please refer to FIG. 1 to FIG. 3, the present invention provides a distribution box, including a box body. The box body includes a bottom plate 1 and side plates, and at least one side plate is a wire passing side plate 2 where wire passing holes are provided. The wire passing side plate 2 includes an outer plate 3 disposed on the outer side and an inner plate 4 disposed on the inner side, and a plurality of through holes 302 are provided on the outer plate 3. The inner plate 4 includes a base part 41 and removable shielding parts 42, and the removable shielding parts 42 are fixed at the base part 41 through a plurality of connecting points 43. The removable shielding parts 42 are disposed corresponding to the through holes 302, and the removable shielding parts 42 shield the through holes 302. The base part 41, the removable shielding parts 42, and the connecting points 43 are integrally formed, and thus the manufacture procedure is simple. When the connecting points 43 are disconnected, the removable shielding parts 42 can be taken away from the base part 41, and the through holes 302 are exposed to serve as the wire passing holes to allow wires to pass through them. A gap is reserved between the removable shielding parts 42 and the base part 41, the removable shielding parts 42 and the base part 41 are connected only via the connecting points 43, and the connecting points 43 can be disconnected by applying a certain external force to the removable shielding parts 42, so as to take away the removable shielding parts 42 from the base part 41. Then the through holes 302 can be exposed, i.e. making holes on the wire passing side plate 2 is completed, so that the hole-making process is very convenient and no special perforation tool is needed, thereby effectively saving the time and hole-making costs. The distribution box provided by the present invention is made of a metal material, preferably made of iron, and a rigid structure is better.

In the embodiment, the removable shielding parts 42 are circular, the through holes 302 are circular holes, and the diameters of the removable shielding parts 42 are larger than those of the through holes 302, such that the removable shielding parts 42 can completely shield the through holes 302 to prevent dust from entering into the box body from the through holes 302. Therefore the dustproof effect is good, and the dust is prevented from entering into the part without holes. However, the shapes of the removable shielding parts 42 and the through holes 302 are not limited hereto and can also be a variety of shapes such as squares, ellipses and polygons and the like, as long as the removable shielding parts 42 can shield the through holes 302. Arc-shaped gaps 412 are formed between the base part 41 and the removable shielding parts 42 to allow a force to be conveniently applied to the removable shielding parts 42 to disconnect the connecting points 43, which facilitates simplifying the hole-making process. Any one of the removable shielding parts 42 can be connected with the base part 41 through two to four connecting points 43. In this embodiment, any one of the removable shielding parts 42 is connected with the base part 41 through three connecting points 43, and when hole-making is not needed, the removable shielding parts 42 can be firmly fixed at the base part 41; and when a hole is needed, the three connecting points 43 can be easily disconnected. Thus the hole-making is very convenient.

The side plate adjacent to the wire passing side plate 2 is a positioning side plate 5, which is used for connecting the wire passing side plate 2 to form a side face of the box body. The positioning side plate 5 is fixed at the edge of the bottom plate 1. The inner plate 4 can be fixed at the bottom plate 1 and/or the positioning side plate 5 in a manner such as welding, adhering, or screw locking, and the inner plate 4 is disposed on the inner side of the wire passing side plate 2 for shielding the through holes 302. In the embodiment, the inner plate 4, the positioning side plate 5, and the bottom plate 1 are an entirety. However, the invention is not limited thereto. In another embodiment (not shown), the inner plate 4, the positioning side plate 5 and the bottom plate 1 can be individual bodies which are separately disposed, the inner plate 4 can be fixed at the outer plate 3, and the outer plate 3 is then fixed at the positioning side plate 5 or the bottom plate 1 thus to form a complete distribution box.
