The following description is presented to enable any person skilled in the art to make and use the application. In the following description, details are set forth for the purpose of explanation. It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known structures and processes are not set forth in detail in order to avoid obscuring the description of the present application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

In the related art, the fireproof structure on the electrical box is usually fixed on the electrical box body by welding or screw fastening, so that a connection gap exists between the fireproof structure and the electrical box body. For example, welding can easily result in a weld gap between the fire-resistant structure and the electrical enclosure, and threaded fastening can easily result in a butt joint gap between the fire-resistant structure and the electrical enclosure. Accordingly, when a fire occurs in the electrical box, the flame may jump out of the connection gap to the outside of the electrical box, causing other components outside the electrical box to fire, resulting in the occurrence and further spread of the fire. Meanwhile, the connection mode easily causes the bulge to be generated between the fireproof structure and the electrical appliance box body, and when the contact of an electronic device in the electrical appliance box is poor, the arc discharge phenomenon easily occurs between the contact of the electronic device and the bulge, the high-temperature ignition of the electronic device is caused, and the risk of arc discharge and ignition is generated. In summary, the fire-proof safety performance of the electrical box in the related art is insufficient.
