Description

Technical Field

[0001] This utility model relates to the field of high-temperature cable technology, specifically to a splicing high-temperature cable. Background Technology

[0002] A cable is a device composed of conductors used to transmit electrical signals, electrical energy, or data. It consists of one or more electrical conductors (usually metal wires) and insulating materials, used to transmit electrical signals from one place to another while protecting them from interference and loss. Spliced ​​high-temperature cables are cables assembled from multiple high-temperature cables using a special connection method. They typically consist of high-temperature cables, insulating materials, metal connectors, and insulating sleeves. A search revealed existing technology (publication number: CN202420303356.1) for a spliced ​​high-temperature cable, which describes how "the deformation displacement of the elastic protective element compresses the misaligned cavity, and the interference generated by the mutual compression of the medium on the elastic protective element when it deforms is achieved by the misaligned cavity, thus ensuring both wiring stability and good deformation space for the high-temperature cable body, improving the versatility and convenience of the device in use." However, in existing technology, the misaligned cavity on the outer side of the high-temperature cable is prone to deformation and collapse when subjected to radial compression, affecting the cable's compressive strength and protective effect. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a spliced ​​high-temperature cable is provided to solve the problem that the elastic protective component of the misaligned cavity on the outside of the high-temperature cable is prone to deformation and collapse when subjected to radial compression, which affects the pressure resistance and protection effect of the high-temperature cable.

[0004] To achieve the above objectives, a splicing high-temperature cable is provided, comprising: a high-temperature cable body, wherein plug ends are provided on the left and right sides of the high-temperature cable body, and a socket end is provided on the right side of the high-temperature cable body. The high-temperature cable body has a first TPU semi-ring and a second TPU semi-ring sleeve attached to its outer end face. A composite support is bonded to the inner ring surface of the first TPU semi-ring and the second TPU semi-ring sleeve. The composite support is located around the high-temperature cable body and the distance between the first TPU semi-ring and the second TPU semi-ring. A left outer sheath and a right outer sheath are fixedly distributed at the left and right ends of the first TPU semi-ring and the second TPU semi-ring sleeve. A plug end and a socket end are covered on the inner side of the right outer sheath and the left outer sheath.

[0005] Furthermore, the right outer sheath, left outer sheath, first TPU semi-ring sleeve and second TPU semi-ring sleeve are fixed symmetrically at the outer end of the high-temperature cable body by fastening bolts.

[0006] Furthermore, the first TPU semi-ring and the second TPU semi-ring are provided with heat dissipation grooves at equal intervals on their annular surfaces; and the heat dissipation grooves are located outside the spacing of the composite support.

[0007] Furthermore, an externally threaded right ring is fixed to the outer surface of the right end of the right outer sheath, and an externally threaded left ring is fixed to the outer surface of the left end of the left outer sheath. A groove is formed on the surface of the externally threaded right ring.

[0008] Furthermore, the outer ring surfaces of the right and left external threaded rings are connected by a splicing ring via threads, and a limiting cable tie is fixed at the groove; the limiting cable tie is located on the side of the splicing ring.

[0009] Furthermore, sealing gaskets are bonded to the inner end faces of the right outer sheath and the left outer sheath, and a heat insulation layer is bonded to the inner side of the sealing gaskets.

[0010] Furthermore, the sealing gasket is wrapped and bonded to the high-temperature cable body through a heat insulation layer.

[0011] The beneficial effects of this utility model are as follows: the spliced ​​high-temperature cable utilizes a first TPU semi-ring, a second TPU semi-ring, and a composite support component surrounding the outer surface of the high-temperature cable. The composite support component, with its own compressive strength and buffering properties, provides support and resists external impacts and pressures, significantly reducing deformation and collapse of the outer TPU ring of the high-temperature cable, enhancing the overall compressive strength of the spliced ​​high-temperature cable, reducing the degree of damage, and improving its durability. The high-temperature cable connects to adjacent high-temperature cables via plug and socket ends, and the splicing ring is protected by the left and right outer sheaths, facilitating the protection of the spliced ​​ends and enabling rapid splicing. This also allows for convenient replacement of faulty ends in case of partial damage, reducing maintenance costs and time. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a splicing high-temperature cable, including: a high-temperature cable body 1, with plug ends 11 on the left and right sides of the high-temperature cable body 1, and a socket end 12 on the right side of the high-temperature cable body 1. The outer end face of the high-temperature cable body 1 is fitted with a first TPU semi-ring sleeve 2 and a second TPU semi-ring sleeve 21. The inner ring surface of the first TPU semi-ring sleeve 2 and the second TPU semi-ring sleeve 21 is bonded with a composite support 24. The composite support 24 is located around the high-temperature cable body 1 and the distance between the first TPU semi-ring sleeve 2 and the second TPU semi-ring sleeve 21. The left outer sheath 31 and the right outer sheath 3 are fixedly distributed on the left and right ends of the first TPU semi-ring sleeve 2 and the second TPU semi-ring sleeve 21. The plug end 11 and the socket end 12 are covered on the inner side of the right outer sheath 3 and the left outer sheath 31.

[0019] When installing the high-temperature cable body 1, firstly, the plug ends 11 and socket ends 12 at both ends of the high-temperature cable body 1 are distributed and connected to the adjacent high-temperature cable plug ends on the left and right sides. The first TPU semi-ring sleeve 2 and the second TPU semi-ring sleeve 21 are screwed and fixed on the outer surface of the high-temperature cable body 1 of equal length. The composite support 24 inside the first TPU semi-ring sleeve 2 and the second TPU semi-ring sleeve 21 is supported on the outside of the high-temperature cable body 1 to support and resist external impact and pressure, enhance the overall compressive strength of the spliced ​​high-temperature cable, and reduce the degree of damage to the spliced ​​high-temperature cable. Then, the splicing ring 5 at the right ring 33 of the external thread of the right outer sheath 3 is rotated so that the splicing ring 5 is screwed at the junction of the right outer sheath 3 and the left outer sheath 31. The right outer sheath 3 and the left outer sheath 31 cover and protect the plug ends of the high-temperature cable body 1, thus completing the splicing installation of the current high-temperature cable body 1.

[0020] In this embodiment, the right outer sheath 3, the left outer sheath 31, the first TPU semi-ring sleeve 2, and the second TPU semi-ring sleeve 21 are symmetrically fixed at the outer end of the high-temperature cable body 1 by fastening bolts 23. The first TPU semi-ring sleeve 2 and the second TPU semi-ring sleeve 21 have heat dissipation grooves 22 at equal intervals on their annular surfaces; and the heat dissipation grooves 22 are located outside the spacing of the composite support member 24.

[0021] As a preferred implementation, the right outer sheath 3, the left outer sheath 31, the first TPU semi-ring 2, and the second TPU semi-ring 21 constitute the external protective structure of the high-temperature cable body 1. This significantly reduces the deformation and collapse of the outer TPU ring of the high-temperature cable, enhances the overall compressive strength of the spliced ​​high-temperature cable, reduces the degree of damage to the spliced ​​high-temperature cable, and improves the durability of the spliced ​​high-temperature cable. The composite support 24 is made of graphene-reinforced silicone material with a convex curved surface, which has excellent compressive strength and wear resistance, and is not easy to crack, further supporting and resisting external impacts and pressures.

[0022] In this embodiment, a right threaded right ring 33 is fixed to the outer surface of the right end of the right outer sheath 3, and a left threaded left ring 32 is fixed to the outer surface of the left end of the left outer sheath 31. A groove 34 is formed on the surface of the right threaded right ring 33. A splicing ring 5 is threadedly connected to the outer ring surfaces of the right threaded right ring 33 and the left threaded left ring 32. A limiting cable tie 4 is fixed at the groove 34, and the limiting cable tie 4 is positioned against the side of the splicing ring 5. A sealing gasket 6 is bonded to the inner end face of the right outer sheath 3 and the left outer sheath 31, and a heat insulation layer 61 is bonded to the inner side of the sealing gasket 6. The sealing gasket 6 is wrapped and bonded to the high-temperature cable body 1 through the heat insulation layer 61.

[0023] As a preferred implementation, the external thread right ring 33 and external thread left ring 32 facilitate the screwing of the splicing ring 5 at the joint of the right outer sheath 3 and the left outer sheath 31. At the same time, the sealing gasket 6 is located in the gap inside the right outer sheath 3 and the left outer sheath 31, so that the joint space of the right outer sheath 3 and the left outer sheath 3 is sealed, preventing external moisture, foreign objects, etc. from interfering with the plug end of the high-temperature cable body 1, and ensuring the stable connection of the plug end of the spliced ​​high-temperature cable.

[0024] This invention provides a spliced ​​high-temperature cable that effectively solves the problem in existing technologies where the misaligned elastic protective component on the outer side of the high-temperature cable easily deforms and collapses under radial compression, affecting the cable's compressive strength and protection. It significantly reduces the deformation and collapse of the outer TPU ring of the high-temperature cable, enhances the overall compressive strength of the spliced ​​high-temperature cable, reduces the degree of damage, and improves its durability. It also facilitates the protection of the splicing ends of the high-temperature cable, enables rapid splicing, and allows for easy replacement of faulty ends in case of localized damage, reducing maintenance costs and time. This invention is suitable for spliced ​​high-temperature cables.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
