Description

Technical Field

[0001] This utility model relates to cable junction boxes, specifically to a low-voltage cable junction box with one inlet and multiple outlets. Background Technology

[0002] Low-voltage cable junction boxes typically consist of a primary copper busbar installed in the junction box. The primary copper busbar has multiple holes for connecting the incoming and outgoing cables, enabling the cable lines to be branched, connected, and switched.

[0003] Currently, the copper busbars of low-voltage cable junction boxes (A, B, C, N, PE) are basically installed vertically on the same plane from left to right or horizontally from front to back. This results in multiple cables being stacked on site, making it inconvenient to install and fix the cable lugs.

[0004] Therefore, how to solve the problem of on-site cable installation and reasonable cable layout is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] Except for the two mounting holes at the bottom, insulators are installed in the mounting holes on each step riser.

[0009] A copper busbar is installed between two insulators at the same height.

[0010] Furthermore, the first support is a metal support formed by continuously bending a strip plate, or the first support is an integral insulating support.

[0011] Furthermore, the low-voltage cable junction box also includes a PE copper busbar, which is installed in two mounting holes at the bottom.

[0012] Furthermore, the low-voltage cable junction box also includes an insulating beam assembly, which is fixed inside the box and located below the first support.

[0013] Furthermore, the insulating beam assembly includes a second bracket laterally fixed inside the housing and an insulating beam fixed to the second bracket, both the second bracket and the insulating beam having a plurality of linearly distributed binding holes.

[0014] Furthermore, the insulating beam is an epoxy board insulating beam.

[0015] Furthermore, the bottom plate of the enclosure is provided with multiple cable passage holes, and each of the multiple copper busbars is provided with a splice lug hole during installation. The multiple cable passage holes are aligned with the multiple splice lug holes.

[0016] Furthermore, the multiple copper busbars are fitted with heat shrink tubing of different colors.

[0018] 1.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Example 1: The specific structure of this utility model is as follows:

[0028] Please refer to the appendix. Figure 1-3 The present invention provides a low-voltage cable junction box with one inlet and multiple outlets, comprising a box body 1 and multiple copper busbars 5. The low-voltage cable junction box also includes two first supports 2, which are installed inside the box body 1 at a distance from each other.

[0029] The first bracket 2 is a stepped, curved mounting component with mounting holes along the stepped risers. Except for the two mounting holes at the bottom, each stepped riser has an insulator 3 installed in its mounting holes; a copper busbar 5 is installed between two insulators 3 at the same height. The low-voltage cable junction box also includes a PE copper busbar 4, which is installed in the two mounting holes at the bottom. Figure 2 As shown, there are four copper busbars 5, plus one PE copper busbar 4, forming a five-phase copper busbar. The five-phase copper busbars are distributed in a staggered manner from high to low in space, that is, the distance between the five-phase copper busbars and the front plate of the housing 1 gradually increases from top to bottom.

[0030] The first support 2 is a metal support formed by continuously bending a strip of plate, or the first support 2 is an integral insulating support. Preferably, in this embodiment 1, the first support 2 is configured as a metal support.

[0031] The low-voltage cable junction box also includes an insulating beam assembly, which is fixed inside the box body 1 and located below the first support 2. The insulating beam assembly includes a second support 7 horizontally fixed inside the box body 1 and an insulating beam 6 fixed to the second support 7. Both the second support 7 and the insulating beam 6 have multiple linearly distributed binding holes. The bottom plate of the box body 1 has multiple cable passage holes. Each of the multiple copper busbars 5 has pre-drilled lap joint lug holes during installation. The multiple cable passage holes are aligned with the multiple lap joint lug holes to reduce cable stress during cable connection. Figure 1As shown, the multiple lap lug holes are linearly distributed wiring holes on copper busbar 5 and PE copper busbar 4, and the wiring holes on copper busbar 5 and PE copper busbar 4 are all aligned. When connecting cables, the 10 cables pass through the cable guide holes, and when passing through the insulation beam assembly, the cables are tied one-to-one with cable ties. The cables are pulled upwards so that their copper lugs align with the corresponding lap lug holes, and then tightened with screws. All 10 cables can be pulled straight without overlapping or bending. The cables inside the entire enclosure are neat and aesthetically pleasing.

[0032] The multiple copper busbars 5 are fitted with heat shrink tubing of different colors. Different colors of heat shrink tubing indicate different functions of the copper busbar 5. For example, red heat shrink tubing indicates that the copper busbar 5 is connected to the live wire, black heat shrink tubing indicates that the copper busbar 5 is connected to the neutral wire, and blue heat shrink tubing indicates that the copper busbar 5 is connected to the ground wire.

[0033] The insulating beam 6 is an epoxy board insulating beam. The epoxy board insulating beam is used to prevent eddy currents from forming when multiple cables pass through it.

[0034] In summary, this utility model's low-voltage cable junction box, through its stepped structure and two first supports, staggers the distribution of multiple copper busbars and one PE copper busbar in the front-to-back direction, preventing cable overlap during connection. The wiring inside the box is neat and aesthetically pleasing. This utility model's low-voltage cable junction box is easy to install and maintain. The copper busbars in this utility model's low-voltage cable junction box do not obstruct each other, facilitating cable installation and removal. Multiple copper busbars are installed horizontally, with each circuit's inlet and outlet cables vertically connected to the copper busbars, resulting in a clear and non-overlapping arrangement.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
