technical field

The utility model relates to the technical field of distribution boxes, in particular to an indoor concealed assembly distribution box.

Background technique

With the development of electric power technology, the application of distribution box is more and more extensive. The distribution box can distribute electric energy reasonably, facilitate the opening and closing operation of the circuit, have a high level of safety protection, and can intuitively display the conduction of the circuit. state, easy to manage, and convenient for maintenance when a circuit failure occurs. In today's building power installation process, the indoor wire routing method is generally a concealed wire routing method, that is, the wires are buried in the wall, and in the prior art, most of the indoor distribution boxes are external power distribution The distribution box, that is, the distribution box is directly installed on the wall through bolts. In this way, when the wires in the wall are connected to the external distribution box, it will bring a lot of inconvenience to the circuit installers and affect the appearance of the wall. On the other hand, the wire inlet holes of existing indoor distribution boxes are generally preset at the factory, and the circuit installers only need to insert the wires through the wire inlet holes. However, the wire inlet holes that the circuit installers need to use The holes are not completely determined. Sometimes more wire inlet holes are needed, and sometimes fewer wire inlet holes are needed. When fewer wire inlet holes are used, indoor dust and debris can easily enter the distribution box through the redundant wire inlet holes Inside. On the other hand, the existing indoor power distribution boxes generally have a single-layer door structure, and the user is likely to touch the metal conductive components in the power distribution box after opening the door of the power box, resulting in a risk of electric shock.
