[0002] Junction boxes are common accessories used in house construction to install electrical wiring, switches, and other components.

[0003] When in use, the junction box is fixed in the mounting groove on the wall, and the cable is threaded into the junction box. In concrete buildings, the distance between the conduit from the junction box and the finished wall surface varies. On the construction site, wet operations such as plastering are generally used to seal the gap.

[0004] However, in new modular buildings, prefabricated panels are generally used for encapsulation. The existing junction boxes have a fixed depth, and the opening positions cannot be effectively connected and coordinated with the panel thickness, which affects the installation and construction. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the fixed depth of existing junction boxes makes it difficult to coordinate with the thickness of modular building panels in modular buildings, thereby providing a junction box and a modular building having it.

[0006] To solve the above-mentioned technical problems, this utility model provides a junction box, comprising:

[0007] The outer box is used for fixed connection with the wall, and the outer box has an opening on the side facing the outside of the wall;

[0008] The mounting frame is slidably disposed at the opening of the outer box. The mounting frame moves along the opening direction of the outer box. When adjusted to a suitable depth, the mounting frame is connected and fixed to the outer box. The mounting frame is used to install the panel.

[0009] Optionally, the mounting frame is provided with a plurality of fixing holes, and the outer box is provided with a plurality of connecting holes opposite to the fixing holes. Some of the fixing holes are used to pass fasteners through and connect with the connecting holes so that the mounting frame and the outer box are connected and fixed. Some of the fixing holes are used to install a panel.

[0010] Optionally, the cross-section of the outer box and the mounting frame is set to square, and each of the four side walls of the mounting frame is provided with a fixing hole, and each of the four side walls of the outer box is provided with a connecting hole.

[0039] This embodiment provides a junction box structure suitable for modular buildings, used for wiring and connection in circuits.

[0040] like Figure 1-3 The diagram shows a specific implementation of a junction box provided in this embodiment, comprising: an outer box 1 and a mounting frame 2. The outer box 1 is used for fixed connection with a wall, and the outer box 1 has an opening on the side facing the outside of the wall. The mounting frame 2 is slidably disposed at the opening of the outer box 1, and the mounting frame 2 moves along the opening direction of the outer box 1. When adjusted to a suitable depth, the mounting frame 2 is connected and fixed to the outer box 1, and the mounting frame 2 is used for mounting a panel.

[0041] In use, the outer box 1 is installed in the mounting groove on the wall. The mounting frame 2 is pulled outward or pushed inward along the opening direction of the outer box 1 to adjust the depth of the junction box so that the end of the mounting frame 2 away from the outer box 1 is flush with the finished surface of the wall. The mounting frame 2 is then connected and fixed to the outer box 1. The panel is installed on the mounting frame 2. Since the depth of the junction box is adjustable, it can be flexibly adjusted according to different wall thicknesses and the space required for the wiring in the junction box, making installation easier and facilitating the coiling and storage of wires. The junction box provided in this embodiment solves the problem that the fixed depth of existing junction boxes makes it difficult to coordinate with the thickness of modular building panels in modular buildings.

[0042] like Figure 1 , Figure 2 As shown, in the junction box provided in this embodiment, the mounting frame 2 is provided with multiple fixing holes 4, and the outer box 1 is provided with multiple connecting holes 5 opposite to the fixing holes 4. Some of the fixing holes 4 are used for fasteners to pass through and connect to the connecting holes 5, so as to connect and fix the mounting frame 2 and the outer box 1. Some of the fixing holes 4 are used for mounting the panel. The fastener passes through the fixing holes 4 and the connecting holes 5 at one time to connect and fix the mounting frame 2 and the outer box 1, so as to prevent the mounting frame 2 from moving during use and causing changes in the depth of the junction box. The remaining fixing holes 4 are used for mounting the panel. In addition, as an alternative embodiment, the connecting holes 5 can be omitted, and a snap-fit ​​structure is provided on the mounting frame 2 and the outer box 1, and the fixing holes 4 are used for mounting the panel.

[0043] like Figure 1 , Figure 2 As shown, in the junction box provided in this embodiment, the outer box 1 and the mounting frame 2 have square cross-sections. Each of the four side walls of the mounting frame 2 has a fixing hole 4, and each of the four side walls of the outer box 1 has a connecting hole 5. Compared to other shapes, the square outer box 1 and the mounting frame 2 provide a larger internal space. By providing a fixing hole 4 and a connecting hole 5 on each of the four sides of the square shape, the connection between the mounting frame 2 and the outer box 1 can be made more stable. Alternatively, as an alternative implementation, the outer box 1 and the mounting frame 2 can also be made into other shapes such as circles or polygons, depending on the design requirements.

[0044] like Figure 1-3As shown, in the junction box provided in this embodiment, the mounting frame 2 is provided with a mounting plate 6 extending towards the inner side of the mounting frame 2, and the fixing hole 4 is provided on the mounting plate 6. By using the mounting plate 6 on the mounting frame 2, the fixing hole 4 is located on the inner side of the mounting frame 2, facilitating installation and avoiding occupying space outside the junction box. Alternatively, as an alternative implementation, the mounting plate 6 can also extend towards the outer side of the mounting frame 2.

[0045] like Figure 1-3 As shown, in the junction box provided in this embodiment, a connecting plate 7 extending inward is provided at the opening of the outer box 1, and the connecting hole 5 is provided on the connecting plate 7. By using the connecting plate 7 on the outer box 1, the connecting hole 5 is located inside the outer box 1, facilitating installation and avoiding occupying space outside the junction box. Alternatively, as an alternative implementation, the connecting plate 7 can also extend outward from the outer box 1.

[0046] like Figure 1 , Figure 2 As shown, in the junction box provided in this embodiment, the mounting frame 2 is provided with a guide portion 3 extending towards the outer box 1. The guide portion 3 is slidably inserted into the interior of the outer box 1. The guide portion 3 slides within the outer box 1, guiding the movement of the mounting frame 2 and causing it to move along the opening direction of the outer box 1, preventing the mounting frame 2 from shifting and affecting installation. Alternatively, as an alternative implementation, the guide portion 3 can be omitted, and the mounting frame 2 moves along a mounting groove on the wall.

[0047] like Figure 1 , Figure 2 As shown, in the junction box provided in this embodiment, the guide portion 3 is configured as a bent structure. The bent structure of the guide portion 3 has better bending resistance, preventing deformation of the guide portion 3 during the sliding of the mounting frame 2, which would cause the mounting frame 2 to shift. Specifically, one guide portion 3 is provided at each of the four corners of the square mounting frame 2. Alternatively, as an alternative implementation, the guide portion 3 can also be configured as a plate-like structure or a column-like structure, etc.

[0048] like Figure 1-3 As shown, in the junction box provided in this embodiment, a plurality of wire-passing holes 8 are provided on the side wall of the outer box 1, and the wire-passing holes 8 are used to pass cables through. The cables are connected to the inside of the junction box through the wire-passing holes 8 on the outer box 1. Specifically, at least one wire-passing hole 8 is provided on each of the four sides of the square outer box 1. In addition, as an alternative implementation, the cables can also be connected through the gap between the mounting frame 2 and the outer box 1.

[0049] like Figure 1-3 As shown, in the junction box provided in this embodiment, a clearance notch 9 is formed between two adjacent guide portions 3. The clearance notch 9 is used to avoid the wire hole 8. The clearance notch 9 can avoid the wire hole 8, preventing the wire hole 8 from being blocked and thus preventing the cable from being connected.

[0050] How to use:

[0051] like Figure 1-3 As shown, in this embodiment, the junction box is installed in the mounting groove on the wall. The mounting frame 2 is pulled outward or pushed inward along the opening direction of the outer box 1 to adjust the depth of the junction box so that the end of the mounting frame 2 away from the outer box 1 is flush with the finished surface of the wall. The mounting frame 2 is connected and fixed to the outer box 1 by fasteners, and the panel is installed on the mounting frame 2.

[0052] In addition, this embodiment also provides a modular building, including a wall and a junction box as described in the above embodiments. The wall is provided with a mounting groove, and the junction box is embedded in the mounting groove.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
