[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of "a plurality" is two or more.

[0028] Referring to Figures 1 to 4 A fully insulated cable branch box shown in the figure includes a cabinet 10, which is assembled and spliced by several side plates. A plurality of reinforcing ribs 20 are provided on at least two opposite side plates, and both ends of all the reinforcing ribs 20 are respectively connected and fixed to the corresponding side plates; a plurality of through holes 11 are provided on both of the two opposite side plates without the reinforcing ribs 20. Cable supports 30 are installed in all the through holes 11. All the cable supports 30 on the same side plate are pressed and fixed on the outer side wall of the corresponding side plate by a mounting pressure plate 40. Sealing rings are provided on the outer sides of all the through holes 11, and the mounting pressure plate 40 presses the sealing ring against the corresponding side plate.

[0029] Among them, the cable support 30 can be replaced with a conventional series joint. Among them, the installation pressing plate 40 can increase the thickness of the corresponding side plate, thereby extending the length of the through hole 11, and to a certain extent, the installation stability of the cable support 30 can be improved. In the above embodiments, all side plates are made of stainless steel. At the same time, for the overall sealing performance, all side plates are fixed by welding, and such a design can improve the strength of the corresponding side plates to a certain extent. The sealing rings can be arranged at both ends of the through hole 11. Among them, the inner side is pressed by the cable support 30, and then cooperates with the outer sealing ring, so as to ensure the connection sealing performance between the cable support 30 and the side plate.

[0030] In some embodiments, in order to facilitate hoisting during the production and assembly process, avoidance holes 21 are provided at both ends of the reinforcing rib 20.

[0031] This fully insulated cable branch box is obtained by welding or connecting multiple side plates, which is convenient for disassembly and assembly and has a simple structure. At the same time, reinforcing ribs 20 are provided on two opposite side plates. By using the reinforcing ribs 20, the strength of the entire box body 10 can be effectively improved. At the same time, the two ends of the reinforcing ribs 20 are respectively connected and fixed to the corresponding side plates, further improving the strength of the box body 10. At the same time, by using the installation pressing plate 40 to press and fix all the cable supports 30 on the outer side wall of the corresponding side plate, the connection stability and dynamic stability of the cable supports 30 can be effectively ensured, avoiding loosening between the cable supports 30 and the through holes 11 caused by the plugging and unplugging actions during practical use. At the same time, the strength of the corresponding side plates is also improved, avoiding deformation due to excessive plugging and unplugging during use, and thus affecting the normal position of the corresponding cable supports 30. At the same time, a sealing ring is also provided between the end face of the through hole 11 on the side plate and the installation pressing plate 40. Such a setting can further improve the insulation strength and water leakage prevention ability of the interface.

[0032] In some possible implementation manners, for the convenience of assembly, the box body 10 is composed of a front plate 12, a rear plate 13, a top plate 14, a bottom plate 15 and two side panels 16 spliced and fixed. The reinforcing ribs 20 are provided on the top plate 14 and the bottom plate 15, and through holes 11 are provided on both the front plate 12 and the rear plate 13. Among them, the reinforcing ribs 20 can be external structures or structures integrally formed with the top plate 14 and the bottom plate 15. Since all the above side plates are made of stainless steel, in order to ensure airtightness and the strength of the side plates, all the reinforcing ribs 20 are bent from metal materials and fixedly connected to the outer walls of the corresponding side plates.

[0033] Among them, in the above embodiments, in order to facilitate understanding the air pressure value of the SF6 filled inside the entire box body 10, mounting holes 17 are provided on the front plate 12 or the rear plate 13. Pressure gauges 50 are respectively installed in the mounting holes 17, and a sealing ring is provided between the installation end of the pressure gauge 50 and the mounting hole 17.

[0034] In the improvement scheme of the above embodiment, in order to avoid damaging the box body 10 due to overvoltage, mounting holes 17 are provided on the bottom plate 15, and a pressure relief valve 60 is installed in the mounting holes 17. A sealing ring is provided between the pressure relief valve 60 and the mounting holes 17.

[0035] Among them, both the pressure relief valve 60 and the pressure gauge 50 are connected to the mounting holes 17 through sealing rings, which overall ensures the sealing performance of the box body 10.

[0036] See Figure 3 , the cable supports 30 installed on the front plate 12 and the rear plate 13 are correspondingly connected through copper bars 31. In this embodiment, the number of cable supports 30 installed on the rear plate 13 is a multiple of the cable supports 30 on the front plate 12, so that multiple cable supports 30 on the rear plate 13 can be connected to a cable support 30 on the front plate 12 at the same time.

[0037] See Figures 1 to 4 , in order to facilitate fixing the cable supports 30 on the side plates, that is, fixing them on the front plate 12 and the rear plate 13, a plurality of through holes 41 are provided on the mounting pressing plate 40. The mounting pressing plate 40 is installed on the corresponding side plate by means of screws passing through the through holes 41. Among them, a plurality of clamping holes 42 adapted to the through holes 11 are provided on the mounting pressing plate 40. The outer end of the cable support 30 passes through the clamping holes 42 movably, and an opening 43 is provided on one side of the clamping holes 42. Among them, the design of the opening 43 can, to a certain extent, provide a certain amount of movement space between the cable support 30 and the mounting pressing plate 40, avoiding excessive friction between the cable support 30 and the inner wall of the clamping holes 42 due to force deformation during the plugging and unplugging process and causing damage.

[0038] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
