[0003] As for the existing distribution box structure for construction sites, its internal terminals are generally fixed side by side on the electrical installation board, or directly fixed on the inner wall of the electrical box in an embedded manner. The above installation method is easy to cause interference when subsequent electrical components such as circuit breakers and circuit breakers are brought into the site. Secondly, no matter whether it is the electrical installation board or the inner wall of the electrical box, the installation process is not directly positioned from the front, which is inconvenient. For this reason, we propose a distribution box for construction sites to solve the above problems. Utility Model Content
