Description

Technical Field

[0001] This utility model relates to the field of concrete MIC prefabricated modular building construction, and in particular to a junction box connector. Background Technology

[0002] In the construction of prefabricated modular concrete buildings, in order to solve the problem of no connection between junction boxes or mismatch between short pipe connections, a junction box connector was specially invented. It can not only ensure a tight and leak-proof connection between junction boxes, but also prevent wires from being exposed in the concrete and damaged. It can also be used directly instead of lock nuts. Its material is PVC polyvinyl chloride, which is economical and widely used.

[0003] Currently, during the installation of pre-embedded concrete and secondary structure junction boxes, the junction boxes are connected by a short conduit or not connected at all. The short conduit connection method has the problem of inconsistent conduit length. If it is too long, it will affect the wiring and panel installation. If it is too short, it will be easy to fall off. If the conduit is not used for connection, the wires will come into direct contact with the concrete, causing damage to the wires.

[0032] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0033] like Figures 1 to 4 As shown in the figure, the present invention provides a junction box connector, including a connecting tube 100 and an adjusting device 200. The connecting tube 100 is used to connect the junction boxes at both ends, so that the wires in one junction box are connected to the other junction box through the connecting tube 100.

[0034] Because the distance between multiple junction boxes is unstable, the length needs to be adjusted by the adjustment device 200 in this application to accommodate the connection of wires between two junction boxes with different spacing.

[0035] In this application, connectors 300 are provided at both ends of the connecting pipe 100. The connectors 300 are used to connect the connecting pipe 100 and the junction box. A through hole 110 is provided inside the connecting pipe 100. An inner tube 310 is formed on the connector 300 corresponding to the through hole 110. The inner tube 310 on the connector 300 is located inside the through hole 110, and the inner diameter of the inner tube 310 is equal to the inner diameter of the through hole 110. Under this structure, the connecting pipe 100 can be sleeved on the outside of the inner tube 310 for connection.

[0036] An abutment ring 320 is provided at one end of the connector 300 away from the connecting pipe 100, and the outer diameter of the abutment ring 320 is larger than the outer diameter of the connecting pipe 100.

[0037] In this embodiment, an abutment groove is provided on the junction box at the position corresponding to the abutment ring 320. The abutment groove connects to the interior of the junction box, and the shape of the abutment groove corresponds to the shape of the abutment ring 320, so that the abutment ring 320 is located in the abutment groove, which facilitates the fixing of the abutment ring 320 in the abutment groove. In this embodiment, the abutment ring 320 can be set as a flange structure and fixed in the abutment groove by screws.

[0038] In this embodiment, the connecting pipe 100 includes two parts, namely a first pipe 120 and a second pipe 130. One end of the first pipe 120 is connected to the junction box through the inner pipe 310 on the connector 300. The end of the first pipe 120 away from the connector 300 is connected to the second pipe 130 through the adjusting device 200. The end of the second pipe 130 away from the adjusting device 200 is also connected to the junction box through the connector 300, so as to facilitate the connection of the two junction boxes.

[0039] In the above, the distance between the first pipe 120 and the second pipe 130 is set by the adjusting device 200, specifically as follows:

[0040] The adjusting device 200 includes a first adjusting member 210 and a second adjusting member 220. The first adjusting member 210 is connected to the first pipe 120, and the second adjusting member 220 is connected to the second pipe 130. The connection method is a threaded rotation connection, so that when the first adjusting member 210 rotates on the first pipe 120, the first adjusting member 210 moves linearly relative to the first pipe 120. Similarly, when the second adjusting member 220 rotates on the second pipe 130, the second adjusting member 220 moves linearly relative to the second pipe 130.

[0041] In this embodiment of the application, the first adjusting member 210 has a first channel 211 and the second adjusting member 220 has a second channel 221. The first channel 211 and the second channel 221 are both connected to the through hole 110, so that the wire in the wire box can pass through the first channel 211 and the second channel 221.

[0042] In the above structure, the first adjusting member 210 is threadedly connected to the first pipe 120; the second adjusting member 220 is threadedly connected to the second pipe 130, and the threads on the first adjusting member 210 and the second adjusting member 220 have opposite directions of rotation.

[0043] To facilitate adjustment of the length of the connecting pipe 100, a connecting member 230 is provided on the first adjusting member 210 and the second adjusting member 220. The connecting member 230 connects the first adjusting member 210 and the second adjusting member 220, so that the first adjusting member 210 is connected to the second adjusting member 220.

[0044] In this embodiment of the application, the docking member 230 mainly includes a first adjusting ring 231 and a second adjusting ring 232. The first adjusting ring 231 and the second adjusting ring 232 are connected through the through cavity of the docking member 230, so that the first adjusting member 210 and the second adjusting member 220 are connected through the through cavity.

[0045] Specifically:

[0046] The first adjusting ring 231 is sleeved on the first adjusting member 210, and the first adjusting member 210 is rotatably connected within the first adjusting ring 231. During rotation, the first adjusting ring 231 and the first adjusting member 210 do not produce relative displacement. The rotation of the first adjusting member 210 within the first adjusting ring 231 allows the first adjusting member 210 to rotate relative to the first pipe 120, resulting in a positional offset between the first adjusting member 210 and the first pipe 120. To facilitate the rotation of the first adjusting member 210, a first rotating groove 2311 is provided within the first adjusting ring 231 at a position corresponding to the first adjusting member 210. A first rotating ring 212 is provided within the first rotating groove 2311. Through the positional relationship between the first rotating groove 2311 and the first rotating ring 212, the first adjusting member 210 does not shift within the first adjusting ring 231 during rotation, facilitating the rotation of the first adjusting member 210.

[0047] Similarly, the second adjusting ring 232 is sleeved on the second adjusting member 220, and the second adjusting member 220 is rotatably connected within the second adjusting ring 232. During rotation, the second adjusting ring 232 and the second adjusting member 220 do not produce relative displacement. The rotation of the second adjusting member 220 within the second adjusting ring 232 allows the second adjusting member 220 to rotate relative to the second pipe 130, resulting in a positional offset between the second adjusting member 220 and the second pipe 130. To facilitate the rotation of the second adjusting member 220, a second rotating groove 2321 is provided within the second adjusting ring 232 at a position corresponding to the second adjusting member 220. A second rotating ring 222 is provided within the second rotating groove 2321 on the second adjusting member 220 at a position corresponding to the second rotating groove 2321. The second rotating ring 222 is located within the second rotating groove 2321. Through the positional relationship between the second rotating groove 2321 and the second rotating ring 222, the second adjusting member 220 does not shift within the second adjusting ring 232 during rotation, thus facilitating the rotation of the second adjusting member 220.

[0048] In the above structure, sealing rings are provided in both the first rotating groove 2311 and the second rotating groove 2321, and the sealing rings seal the first rotating ring 212 and the second rotating ring 222.

[0049] The threads of the first adjusting member 210 and the second adjusting member 220 are opposite in direction, and the outer surface of the mating member 230 is provided with anti-slip texture. When the mating member 230 is rotated synchronously, the first pipe 120 and the second pipe 130 move in opposite directions symmetrically.

[0050] A first scale mark is provided at the connection between the first adjusting member 210 and the first pipe 120, and a second scale mark is provided at the connection between the second adjusting member 220 and the second pipe 130.

[0051] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
