[0002] During the design and construction of outdoor concealed wire pipelines in buildings, when a branch line is separated from the main line, a branch junction box needs to be installed. If the line is long, even if there is no joint or branch on it, an intermediate junction box must be installed according to the specifications to facilitate the construction of the wire box and maintenance after power is supplied. At present, the junction box is mainly composed of a box body and a box cover. The box body is provided with a wiring hole and a wiring terminal is installed inside. The wire passes through the wiring hole on the box body and enters the junction box and is electrically connected to the corresponding wiring terminal. At present, the box cover of the junction box is fixed with the box body, which is very inconvenient to disassemble and assemble. Moreover, the wiring holes on the junction box are generally of fixed specifications. However, there are differences in the thickness of the wires used in the actual construction process. When the wire is thicker, it cannot be inserted into the wiring hole. When the wire is thinner, it cannot be effectively fixed after passing through the wiring hole and is easy to shake, resulting in poor universality of the junction box. Therefore, a new type of junction box for building electrical design is developed. Utility Model Content
