Description

Technical Field

[0001] This application relates to the field of junction box technology, and more specifically, to a split-type junction box. Background Technology

[0002] In building construction, sockets are usually installed by pre-embedded junction boxes. For example, the most common 86 box refers to a junction box with a cross-sectional size of 86mm×86mm.

[0003] In existing technologies, power cables, network cables, etc., are installed in conduits, which then connect to pre-embedded junction boxes. However, the number and power of electrical equipment vary in different buildings or locations within buildings, resulting in differences in the number and thickness of cables. This leads to corresponding variations in the diameter of the conduits used to run these cables. (For example, the number and power of electrical equipment installed on piers in public areas such as stations and subways are relatively large, thus requiring larger conduit diameters.) Junction boxes typically require two conduits connected as input and output terminals respectively. When the conduit diameter is too large (e.g., 44mm in some scenarios), it is impossible to install two conduits on the same side of an 86mm junction box. In this case, custom-made junction boxes of special dimensions are needed to meet the requirements. In other words, existing junction boxes cannot accommodate conduits of different diameters according to actual conditions, causing inconvenience during construction and increasing production costs.

[0004] Therefore, it was necessary for the inventor to design a new junction box to overcome the above problems. Summary of the Invention

[0005] The main objective of this application is to provide a split-type junction box to solve the problem in related technologies that junction boxes cannot accommodate conduits of different diameters according to actual needs.

[0006] To achieve the above objectives, this application provides a split-type junction box, comprising a junction box base plate and several junction box frames, the junction box frames being connected end to end, the junction box base plate covering the innermost junction box frame, and the junction box base plate being fixedly connected to all the junction box frames; a large-diameter connection port and two small-diameter connection ports are fixedly provided on each junction box frame, a large-diameter sealing plate is fixedly provided at the large-diameter connection port, and a small-diameter sealing plate is fixedly provided at each of the small-diameter connection ports, and the large-diameter connection port and the large-diameter sealing plate, as well as the small-diameter connection port and the small-diameter sealing plate, are fixedly connected by a connecting structure.

[0007] Optionally, one end of the junction box frame has a plug-in portion, and the outer wall of the plug-in portion abuts against the inner wall of the junction box frame.

[0008] Optionally, the wire box frame is rectangular.

[0009] Optionally, the bottom plate of the junction box has a mating portion adapted to the plug-in portion, and the outer side of the plug-in portion abuts against the inner wall of the mating portion.

[0010] Optionally, a number of locking structures are provided between the bottom plate of the junction box and all the junction box frames.

[0011] Optionally, the locking structure includes a threaded cylinder, a plug-in sleeve, and a screw. The threaded cylinder is fixedly mounted on the bottom plate of the junction box, the plug-in sleeve is fixedly mounted on the inner wall of the junction box frame, and the screw passes through all the plug-in sleeves and is threadedly connected to the threaded cylinder.

[0029] like Figures 1 to 4 As shown, a split-type junction box includes a junction box base plate 1 and several junction box frames 2, which are connected end to end. The junction box base plate 1 covers the innermost end of the junction box frame 2, and the junction box base plate 1 is fixedly connected to all the junction box frames 2. A large-diameter connection port 3 and two small-diameter connection ports 4 are fixedly provided on the junction box frame 2. A large-diameter sealing plate 5 is fixedly provided at the large-diameter connection port 3, and a small-diameter sealing plate 6 is fixedly provided at the small-diameter connection ports 4. The large-diameter connection port 3 and the large-diameter sealing plate 5, as well as the small-diameter connection port 4 and the small-diameter sealing plate 6, are all fixedly connected by a connecting structure.

[0030] Specifically, the number of junction box frames 2 is selected according to actual needs. When there are many cables in the conduit and the conduit diameter matches the large-diameter connection port 3, two or more junction box frames 2 can be connected end to end in a direction perpendicular to the wall. When connecting large-diameter conduits, disconnect the connection structure between the large-diameter sealing plate 5 and the large-diameter connection port 3, remove the large-diameter sealing plate 5, and then connect the conduit to the large-diameter connection port 3 for installation. When the required conduit diameter is small, only one junction box frame 2 can be pre-embedded. When connecting small-diameter conduits, disconnect the connection structure between the small-diameter sealing plate 6 and the small-diameter connection port 4, remove the small-diameter sealing plate 6, and then connect the conduit to the small-diameter connection port 4 for installation. During assembly, simply fix the junction box frame 2 to the junction box base plate 1. Here, the junction box base plate 1 and junction box frame 2 are set separately, which makes the mold for these two components simpler during production and also makes it easier for workers to select and install them according to actual needs.

[0031] One end of the junction box frame 2 has a plug-in portion 7, the outer wall of which abuts against the inner wall of the junction box frame 2. Specifically, the plug-in portion 7 and the junction box frame 2 are integrally formed. When the plug-in portion 7 is inserted into the junction box frame 2, the outer walls of two adjacent junction box frames 2 transition smoothly, facilitating subsequent assembly and disassembly. Besides this structure, other structures that allow the junction box frames 2 to be connected end-to-end can also be used here.

[0032] The junction box frame 2 is rectangular. Specifically, most junction boxes are rectangular, but for aesthetic purposes, the junction box frame 2 can be set to hexagonal, octagonal, or other shapes.

[0033] The junction box base plate 1 has a mating part 8 that matches the plug-in part 7, and the outer side of the plug-in part 7 abuts against the inner wall of the mating part 8. Specifically, the mating part 8 and the plug-in part 7 are matched in size, and after mating, the outer wall of the plug-in part 7 and the outer wall of the junction box frame 2 have a smooth transition, resulting in a more aesthetically pleasing and standardized appearance.

[0034] Several locking structures are provided between the junction box base plate 1 and all the junction box frames 2. Each locking structure includes a threaded cylinder 9, a plug-in sleeve 10, and a screw 11. The threaded cylinder 9 is fixedly mounted on the junction box base plate 1, the plug-in sleeve 10 is fixedly mounted on the inner wall of the junction box frame 2, and the screw 11 passes through all the plug-in sleeves 10 and is threadedly connected to the threaded cylinder 9. Specifically, after the screw 11 and the threaded cylinder 9 are threadedly locked, the larger end of the screw 11 presses against the plug-in sleeve 10 on the outermost junction box frame 2, pressing all the junction box frames 2 into a single unit, thus achieving a stable connection between all the junction box frames 2 and the junction box base plate 1.

[0035] Both the large-diameter sealing plate 5 and the small-diameter sealing plate 6 are integrally formed with the junction box frame 2. The connection structure includes multiple connection points 12 formed when the junction box frame 2 is cut discontinuously. During actual assembly, construction workers can destroy the connection points 12 by knocking or other means, thereby knocking off the large-diameter sealing plate 5 and the small-diameter sealing plate 6.

[0036] The small-diameter connection port 4 is fixedly mounted on the large-diameter sealing plate 5. Specifically, the small-diameter sealing plate 6 is a part of the large-diameter sealing plate 5. This design reduces the machining surface area and improves machining efficiency.

[0037] The cable box frame 2 and the cable box base plate 1 are made of either plastic or metal.

[0038] This embodiment sets up a junction box frame 2 with the ends connected, and sets large-diameter and small-diameter mating interfaces of different diameters on the junction box frame 2, so that users can select the number of junction boxes and the diameter of the mating interface with the conduit according to the actual situation when pre-burying the junction boxes.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
