Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, in particular to a spliced ​​junction box. Background Art

[0002] A junction box is a device for electrical connection, usually installed in a circuit, used to connect and distribute wires, cables or other electrical equipment. Announcement No. CN220711055U announces a junction box, including a base, a box body is fixedly connected at the midpoint of the upper end surface of the base, and connecting mechanisms are fixedly arranged on both sides of the box body near the front and rear ends, and the connecting mechanism includes a threaded sleeve and a threaded tube, a connecting tube is fixedly sleeved on the inner side of the threaded tube, and a combined tube is fixedly sleeved on the inner side of the threaded sleeve. In this utility model, when the wire is connected to the box body, the rubber sleeve is used to fill the gap between the connecting tube and the wire through the connecting mechanism and the rubber sleeve to prevent water vapor and dust from entering the box body through the connecting mechanism, thereby improving the sealing of the junction box. At the same time, multiple positioning blocks are used to stably fix wires of different specifications on the upper end of the second arc plate in the fixed cavity through the adjustment mechanism and the fixing mechanism, which not only prevents the wires from easily falling off from the box body, but also facilitates the arrangement of the lines in the box body. However, the box body and the box cover on the junction box are fixed by bolts, so that when opening the junction box, a tool needs to be used to tighten the bolts, which is troublesome to operate and reduces the opening efficiency of the junction box. The junction box still has shortcomings and needs to be improved. Utility Model Content
