Description

Technical Field

[0001] The utility model relates to the field of junction boxes, in particular to an assembled junction box. Background Art

[0002] In home decoration, the junction box is one of the electrical auxiliary materials, because the wires used for decoration are passed through the wire conduit, and the junction box is used as a transition at the joint of the wires (for example, the line is relatively long, or the wire conduit needs to turn a corner). The wire conduit is connected to the junction box, and the wires in the conduit are connected in the junction box, which plays the role of protecting the wires and connecting the wires. This is the junction box.

[0003] After extensive searching, it was found that the prior art publication number is CN218549422U, which discloses a junction box comprising a box body, a cover body and a force-applying member. The box body has a accommodating cavity with a front opening; the cover body can selectively cover or open the front opening; the outer surface of the box body and the outer surface of the cover body are respectively provided with at least one force-applying member. The embodiment of the present application provides a junction box, by respectively providing at least one force-applying member on the outer surface of the force-applying member box body and the outer surface of the cover body. In the process of disassembling and assembling the junction box, the force-applying members respectively provided on the box body and the cover body can provide a fulcrum for disassembling and assembling the junction box, and the operator can more conveniently achieve the closing or separation between the box body and the cover body by touching the force-applying members on the box body and the cover body respectively.

[0004] Therefore, based on the above search and in combination with the existing ones, the junction boxes in the above patents are not convenient for assembling multiple junction boxes together during use, and most of the existing junction boxes are assembled together by directly snapping together without further fixing. During the use of the junction boxes, there are situations where multiple junction boxes need to be used at one time. If the junction boxes are not assembled together, the placement of the junction boxes will appear to be messy, affecting the appearance. It is also inconvenient to classify the junction boxes. Moreover, the wiring holes in the above patents do not have a mechanism for fixing and limiting the cables connected to the junction boxes. As a result, during use, there is a situation where the cables are subjected to external force or long-term use, causing them to fall off from the wiring terminals. Utility Model Content
