[0002] In power transmission and distribution systems, crosslinked rubber wire as a key electrical connection element, its performance is directly related to the safety and reliability of the whole system. The traditional crosslinked rubber wire design often only focuses on the basic insulation and conduction function, and there are deficiencies in anti-breaking, bending resistance and laying convenience. Especially in some complex laying environment, such as corners, inside pipes, etc., the traditional crosslinked rubber wire often can not meet the actual demand.

[0003] Specifically, the traditional crosslinked rubber wire is easy to break or bend when subjected to external force, resulting in a decrease in insulation performance, and even causing safety hazards such as electric leakage and short circuit. In addition, the traditional crosslinked rubber wire often needs to use additional fixing parts or adhesives to ensure its stability when laying, which not only increases the laying cost, but also reduces the construction efficiency.

[0004] Therefore, the market urgently needs a crosslinked rubber wire with anti-breaking structure, strong bending resistance and convenient laying to meet the growing demand for power transmission and distribution. SUMMARY

[0005] The utility model aims at providing a crosslinked rubber wire with anti-breaking structure to solve the problems raised in the background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a crosslinked rubber wire with anti-breaking structure, comprising an outer insulation layer, an inner insulation layer is arranged on the inner side of the outer insulation layer, a plurality of insulation limit strips are fixed inside the inner insulation layer, a wrapping layer is arranged between adjacent two insulation limit strips, a conductor is wrapped inside the wrapping layer, a connecting surface is arranged on the outer ring surface of the outer insulation layer, and a glue clamping groove is arranged on the surface of the connecting surface.

[0007] Preferably, the outer ring diameter of the inner insulation layer is smaller than the inner ring diameter of the outer insulation layer, an annular groove is reserved between the outer insulation layer and the inner insulation layer, a plurality of connecting glue strips are fixed inside the annular groove, the plurality of connecting glue strips are distributed at equal distances and equal sizes in a circle with the inner insulation layer as the center axis, and the wire lengths of the outer insulation layer, the connecting glue strips and the inner insulation layer are equal.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] The crosslinked rubber wire with the anti-breaking structure provided by the utility model is provided with a reserved annular groove between the outer insulation layer and the inner insulation layer, and a plurality of connecting rubber strips are fixed, thereby forming a plurality of anti-bending structures. This design enables the wire body to disperse stress when subjected to external force, thereby avoiding breakage caused by excessive stress on a single point.

[0019] Please refer to Figs. 1-3 The utility model provides a technical scheme: a crosslinked rubber wire with anti-breaking structure, which comprises an outer insulation layer 1, the inner side of the outer insulation layer 1 is provided with an inner insulation layer 3, the outer ring diameter of the inner insulation layer 3 is less than the inner ring diameter of the outer insulation layer 1, an annular groove is reserved between the outer insulation layer 1 and the inner insulation layer 3, a plurality of connecting rubber strips 2 are fixed in the annular groove, the plurality of connecting rubber strips 2 are circumferentially distributed at equal distances and equal sizes with the inner insulation layer 3 as the central axis, and the wire lengths of the outer insulation layer 1, the connecting rubber strips 2 and the inner insulation layer 3 are equal.

[0020] In use, the outer insulation layer 1, the connecting rubber strips 2 and the inner insulation layer 3 form a protective layer against breaking, that is, an annular groove body is formed between the outer insulation layer 1 and the inner insulation layer 3, even if the outer insulation layer 1 breaks, the inner insulation layer 3 on the inner side of the outer insulation layer 1 will not be damaged, even if both the outer insulation layer 1 and the inner insulation layer 3 are damaged in extreme cases, however, the annular groove between the outer insulation layer 1 and the inner insulation layer 3 leaves a separation distance between the inner insulation layer 3 and external objects, thereby avoiding direct contact of the leakage hidden danger existing in the inner insulation layer 3 with external objects, and after the outer insulation layer 1 and the inner insulation layer 3 are additionally provided with the connecting rubber strips 2, a plurality of anti-bending structures are formed between the outer insulation layer 1 and the inner insulation layer 3.

[0021] A plurality of insulation limiting strips 4 are fixed in the inner insulation layer 3, a wrapping layer 6 is arranged between adjacent two insulation limiting strips 4, the insulation limiting strip 4 has a triangular prism structure, one side of the insulation limiting strip 4 is a circular arc curved surface, is fixed to the inner wall of the inner insulation layer 3, the other two sides of the insulation limiting strip 4 are circular arc curved surfaces, are fixed to the outer wall of the wrapping layer 6, a through hole 5 is formed in the surface of the insulation limiting strip 4, and the inner insulation layer 3 is wrapped with a conductor 7.

[0022] In use, a plurality of insulation limiting strips 4 are arranged in the inner insulation layer 3, not only realizing the separation of a plurality of conductors 7, but also forming an anti-breaking structure in the inner insulation layer 3.

[0023] The outer ring surface of the outer insulation layer 1 is provided with a connecting surface 8, the long side length of the connecting surface 8 is equal to the long side length of the outer insulation layer 1, a groove 9 is formed in the surface of the connecting surface 8, the groove 9 is a circular arc curved surface, the long side length of the groove 9 is equal to the long side length of the connecting surface 8, a rubber clamping groove 10 is formed in the surface of the connecting surface 8, the rubber clamping groove 10 is provided with two groups, the two groups of rubber clamping grooves 10 are symmetrically distributed about the groove 9, each group of rubber clamping grooves 10 is provided with a plurality of rubber clamping grooves 10, and the plurality of rubber clamping grooves 10 are arranged and distributed at equal distances and equal sizes along the long side of the connecting surface 8.

[0024] When in use, the connecting surface 8 and the glue slot 10 are arranged on the outer wall of the outer insulation layer 1. When laying the glue slot 10, the connecting surface 8 is in contact with the wall surface or other laying substrates, thereby increasing the contact area between the outer insulation layer 1 and the wall surface. When the outer insulation layer 1 is bonded to the wall surface by using glue, the glue extends into the glue slot 10. After the glue solidifies, the connection between the outer insulation layer 1 and the wall surface is improved. The groove 9 is arranged on the surface of the connecting surface 8. When the wire body is coiled, the groove 9 is arranged on the outer side of the outer insulation layer 1, thereby facilitating the overall coiling of the wire body.

[0025] The use process of the wire body specifically includes the following steps:

[0026] The anti-breaking principle is that the outer insulation layer 1 cooperates with the inner insulation layer 3. The annular groove between the outer insulation layer 1 and the inner insulation layer 3 is designed to ensure that even if the outer insulation layer 1 is damaged, the inner insulation layer 3 can still remain intact and provide continuous insulation protection. The connecting glue strip 2 is arranged between the outer insulation layer 1 and the inner insulation layer 3 at equal distances and sizes to form multiple anti-bending structures, effectively absorb and disperse bending stress, and prevent the wire body from breaking.

[0027] The insulation and separation principle is that the insulation limiting strip 4 has a three-prism structure, which can be firmly fixed to the inner wall of the inner insulation layer 3 and the outer wall of the wrapping layer 6 to effectively separate and insulate the conductor 7. Meanwhile, the perforations 5 on the insulation limiting strip 4 (if used for fixation or insulation enhancement) further improve the overall insulation performance. The wrapping layer 6 tightly wraps the conductor 7 and cooperates with the insulation limiting strip 4 to ensure that the conductor does not loosen or expose, thereby providing additional insulation protection.

[0028] The connection and fixation principle is that the connecting surface 8 is arranged on the outer ring surface of the outer insulation layer 1 to facilitate the contact and connection between the wire body and the wall surface or other substrates. The glue slot 10 provides additional fixation points for the glue, thereby making the connection between the outer insulation layer 1 and the wall surface more stable. After the glue extends into the glue slot 10 and solidifies, the stability and durability of the connection are significantly improved. The groove 9 facilitates the coiling of the wire body when needed, thereby reducing the occupied space and facilitating the carrying and transportation. The design of the groove 9 also enables the wire body to be more tightly fitted when coiled, thereby avoiding looseness and disorder.

[0029] The cross-linked rubber wire has excellent insulation performance, anti-breaking ability, and convenient laying mode through the cooperation of the outer insulation layer 1, the connecting glue strip 2, the inner insulation layer 3, the insulation limiting strip 4, the wrapping layer 6, and the conductor 7. The design of the connecting surface 8 and the glue slot 10 further improves the connection stability and durability of the wire body and the wall surface or other substrates.

[0030] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
