Description

Technical Field

[0001] This invention relates to the field of cable plug-in technology, specifically an insulating, wear-resistant, and weather-resistant cable plug-in. Background Technology

[0002] Cable plugs are key components used to connect or disconnect cables from electrical equipment in high-voltage power systems. They are characterized by full insulation, full sealing, and live operation capabilities, and are widely used in equipment such as distribution transformers, ring main units, and cable branch boxes.

[0003] However, the existing cable plug-in structure, which is integrally bonded to plastic, while improving its wear and weather resistance, makes it difficult to dissipate heat generated during operation. This can easily soften the integrally bonded solid plastic, reducing its service life. Furthermore, the large area of ​​solid plastic not only fails to meet practical requirements but also increases the cost of plastic usage. Therefore, to address these issues, an insulated, wear-resistant, and weather-resistant cable plug-in is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an insulated, wear-resistant, and weather-resistant cable plug to solve the above-mentioned problems.

[0005] The present invention achieves the above-mentioned objective through the following technical solution: an insulating, wear-resistant, and weather-resistant cable plug, comprising a cavity portion located inside a plastic insulating component and an insulating finned tube, wherein the cavity portion is provided with an insulating filler, and the insulating finned tube is partially distributed in the insulating filler, and one side of the conductive core portion located in the cavity portion is configured as an arched section, and both ends of the insulating finned tube are located in the space outside the plastic insulating component.

[0006] In a further technical solution, the cavity is connected to the surface of the plastic insulating component through a threaded interface, and a short plastic cylinder is integrally provided on the inner port edge of the threaded interface.

[0007] A further technical solution is that the surface of the plastic short cylinder is provided with arc-shaped holes, and the bottom of the plastic short cylinder is provided with an internally threaded protrusion tube, wherein the height dimension between the upper and lower inner walls of the arc-shaped hole is smaller than the wall thickness dimension of the plastic short cylinder.

[0008] In a further technical solution, the internally threaded protruding tube is connected to one end of the screw, and the other end of the screw passes through the threaded interface and is fixedly connected to the middle position inside the threaded cover.

[0009] In a further technical solution, the surfaces of other parts of the conductive core are integrally connected with parts of the plastic insulating component.

[0010] In a further technical solution, the two ends of the plastic insulating component are respectively configured as a first plug-in end and a second plug-in end.

[0011] A further technical solution is that a retractable part is provided on one side of the plastic insulating component.

[0012] In a further technical solution, the insulating filler is not limited to mineral insulating oil. The beneficial effects of this invention are: Hollow section: It can reduce the amount of plastic used, and can be filled with insulating filler for insulation and cooling; Insulated finned tubes: Insulated finned tubes are placed in insulating filler, with both ends of the insulated finned tubes placed in the external space, so that the external air flows into the interior of the insulated finned tubes and then flows out, dissipating heat. The heat absorption and dissipation are fast. The arched section located on the conductive core has the structural function of elastic deformation, which can elastically adjust the orientation of the first plug-in end and the second plug-in end, and better cope with the complex plug-in connection space structure. Plastic insulation components: Made of EPDM rubber, which has good adhesion to the conductive core, ensuring the integration of cable accessories, and has excellent wear resistance and weather resistance. By tightly closing the arc-shaped hole and combining it with a threaded cap, a double seal is achieved, preventing leakage of the insulating filler inside the cavity after injection.

[0020] Please see Figure 1-3 As shown, an insulating, wear-resistant, and weather-resistant cable plug includes a cavity 110 located inside a plastic insulating component 1 and an insulating finned tube 5. The cavity 110 is provided with an insulating filler 6, and the insulating finned tube 5 is partially distributed in the insulating filler 6. One side of the conductive core 2 located in the cavity 110 is provided with an arched section 210. Both ends of the insulating finned tube 5 are located in the space outside the plastic insulating component 1. Cavity 110: It can reduce the amount of plastic used and can be filled with insulating filler 6 for insulation and cooling. Insulating finned tube 5: The insulating finned tube 5 is placed in the insulating filler 6, and the two ends of the insulating finned tube 5 are placed in the external space so that the external air flows into the interior of the insulating finned tube 5 and then flows out, dissipating the heat. The heat absorption and heat dissipation are fast. The arched segment 210 located on the conductive core 2 has an elastic deformation structure, which can elastically adjust the orientation of the first plug-in end 130 and the second plug-in end 140 to better cope with the complex plug-in connection space structure. Plastic insulation component 1: Made of EPDM rubber, it has good adhesion to the conductive core 2, ensuring the integration of cable accessories and possessing excellent wear resistance and weather resistance.

[0021] The cavity 110 is connected to the surface of the plastic insulating component 1 through the threaded interface 120, and a plastic short tube 3 is integrally provided on the inner port edge of the threaded interface 120.

[0022] like Figure 2 As shown, the surface of the plastic short tube 3 is provided with arc-shaped holes 310, and the bottom of the plastic short tube 3 is provided with an internally threaded protruding tube 320, wherein the height dimension between the upper and lower inner walls of the arc-shaped hole 310 is smaller than the wall thickness dimension of the plastic short tube 3. The internally threaded protruding tube 320 is connected to one end of the screw 410, and the other end of the screw 410 passes through the threaded interface 120 and is fixedly connected to the middle position inside the threaded cover 4. The specific implementation steps for the plastic short tube 3 are as follows: The threaded cap 4 is first gradually screwed onto the threaded interface 120, and one end of the screw 410 gradually approaches the inside of the contact hole of the internal threaded protrusion tube 320. The threaded cap 4 is always rotating in the original position, so that the driven screw 410 is threadedly connected to the inside of the internal threaded protrusion tube 320. At the same time, it achieves the effect of shrinking and squeezing the plastic short tube 3 connected to the internal threaded protrusion tube 320. By tightly closing the arc-shaped hole 310, it plays a double sealing role inside and outside, preventing the leakage of the insulating filler 6 inside the cavity 110 after it is injected.

[0023] The other parts of the conductive core 2 are integrally connected to a portion of the plastic insulating component 1.

[0024] The two ends of the plastic insulating component 1 are respectively configured as a first plug-in end 130 and a second plug-in end 140.

[0025] like Figure 3 As shown, a telescopic part 150 is provided on one side of the plastic insulating part 1. The telescopic part 150 is used to increase the displacement of the second plug-in end 140 and reduce the degree of pulling and tearing.

[0026] The insulating filler 6 is not limited to mineral insulating oil.
