[0002] A cable is a collection of electrical conductors used for the transmission of electricity, communication, or signals. It consists of one or more conductors (usually copper or aluminum) and an outer insulating protective layer, designed to safely and efficiently transmit electrical energy or signals under various environmental conditions. Based on their application and structure, cables can be classified as power cables, communication cables, control cables, and special cables. Cable insulation is a crucial component ensuring the safe and efficient operation of cables. It involves different levels of materials and design to protect the internal conductors of the cable from current leakage, external interference, mechanical damage, and environmental influences.

[0003] Cables installed outdoors in certain locations are exposed to extreme temperature changes due to the lack of shelter, which can cause the outer insulation material to age or become brittle, thus affecting its insulation performance. Prolonged exposure to sunlight (ultraviolet radiation) can also cause the insulation material to degrade, becoming brittle and prone to breakage, easily reducing the service life of the cable and its outer insulation layer. Utility Model Content

[0004] The purpose of this utility model is to provide a cable welding insulation protection structure, which solves the problem that existing cable welding insulation protection structures are prone to aging or embrittlement of the cable's outer insulation layer material due to extreme changes in high and low temperatures, and degradation of the insulation material due to prolonged exposure to sunlight, making it fragile and easy to break, thus easily reducing the service life of the cable and its outer insulation layer.

[0042] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0043] In this embodiment of the utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used to describe the relative positional relationships of the components in relation to the directions shown in the accompanying drawings or in relation to the vertical, perpendicular, or gravitational directions.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0045] Figure 1 This is a schematic diagram of an insulating protection structure according to one embodiment of the present invention. Figure 2 This is a schematic diagram of an insulating protective structure according to one embodiment of the present invention. In this figure, the insulating protective structure includes two sets of arc-shaped protective shells 1 and an insulating component 5. The two sets of arc-shaped protective shells 1 are fitted onto the outside of the cable, and a splicing component 2 is disposed at the junction of the two sets of protective shells 1 to connect them. Further, to ensure the stability of the connection, the splicing component 2 also includes a connecting strip 21 and a connecting post 22. The connecting strip 21 connects to one set of the two sets of protective shells 1 and has an axially penetrating hollow portion. The connecting post 22 connects to the other set of the two sets of protective shells 1 and is staggered with the connecting strip 21, used to insert into the hollow portion to connect the two sets of protective shells 1. The insulating protective structure, by fitting the two sets of arc-shaped protective shells 1 onto the outside of the cable and utilizing the staggered insertion of the connecting strip 21 and the connecting post 22 of the splicing component 2, achieves axial locking and radial fixation of the two sets of arc-shaped protective shells 1, forming a tightly wrapped insulating layer around the cable, preventing loosening and isolating it from external electric shock or environmental erosion. The use of splicing component 2 enables the rapid assembly and disassembly of the cable and protective shell 1, facilitating the regular replacement of protective shell 1.

[0046] In this embodiment, the specific structure of the connecting post 22, provided that it can be engaged with the connecting strip 21, can be of various types known to those skilled in the art. In one example of this utility model, such as... Figure 3 As shown, the connecting column 22 includes a base 221, an elastic element 222, a splicing column 223, and a force-blocking element 224. The base 221 has a groove. The elastic element 222 is disposed within the groove, with one end fixedly connected to the bottom of the base 221 and the other end fixedly connected to the splicing column 223. The force-blocking element 224 is fixedly connected to the top of the elastic element 222 and the top of the splicing column 223. During assembly, the force-applying shield 224 pulls the splicing column 223 into the groove of the base 221 and compresses the elastic element 222. The elastic element 222 compresses and stores energy, then brings the two arc-shaped protective shells 1 together. Because the connecting column 22 and the connecting strip 21 are interlaced, when the force-applying shield 224 is released, the elastic element 222 releases its elastic force, allowing the splicing column 223 to enter the hollow part of the connecting strip 21, and the two sets of arc-shaped protective shells 1 are assembled. When the elastic element 222 is at its original length, one end of the splicing column 223 extends to the outside of the base 221, and the force-applying shield 224 seals the opening of the groove in the base 221 to prevent foreign objects from entering the groove.

[0047] In this embodiment, the type of elastic element 222 can be various that are known to those skilled in the art, provided that restoring force is provided. In one example of this utility model, the elastic element 222 can be a spring.

[0048] Considering the need to prevent performance degradation or damage to the cable due to high temperatures, this embodiment further includes a pure aluminum reflective film 3 in the insulation protection structure. Compared to ordinary reflective films, the pure aluminum reflective film 3 can save 20% of heat loss. This reflective film not only has excellent heat reflection performance, effectively reflecting and reducing heat generated by solar radiation or other heat sources, but also effectively enhances the cable's shielding, lightning protection, and corrosion resistance. This improves the cable's efficiency and extends its service life, ensuring the cable's stability and safety in various environments. The pure aluminum reflective film 3 can be installed in various ways known to those skilled in the art. In one example of this invention, such as... Figure 4 As shown, the protective shell 1 is provided with an attachment groove 11 along the axial direction, and the attachment groove 11 is snapped into the pure aluminum reflective film 3.

[0049] In this embodiment, the relative position of the fixed pure aluminum reflective film 3 and the attachment groove 11 can be varied as known to those skilled in the art. In one example of this invention, a limiting strip 12 is provided inside the attachment groove 11, which can block and limit the pure aluminum reflective film 3. To make the pure aluminum reflective film 3 more securely attached, adhesive can be applied to both sides of the pure aluminum reflective film 3 to more firmly attach it to the attachment groove 11.

[0050] In this embodiment, the number of limiting strips 12 can be multiple as known to those skilled in the art. In one example of this utility model, the number of limiting strips 12 can be 10.

[0051] To further prevent performance degradation or damage to the cable due to high temperatures, in this embodiment, the insulation protection structure also includes a pure arc-shaped heat insulation layer 4. The specific location of this arc-shaped heat insulation layer 4 can be various as known to those skilled in the art; in one example of this invention, it is disposed between the protective shell 1 and the cable.

[0052] In this embodiment, the material of the arc-shaped heat insulation layer 4 can be any of those known to those skilled in the art. In one example of this utility model, the material of the arc-shaped heat insulation layer 4 can be polyurethane foam. Polyurethane foam has good insulation properties, moisture resistance, corrosion resistance, temperature adaptability, and heat transfer reduction. It helps prevent current leakage, prevents moisture from penetrating into the cable interior, reduces the risk of insulation failure, protects the cable in harsh environments, maintains its performance over a wide temperature range, adapts to various environmental conditions, and its low thermal conductivity can reduce heat transfer caused by current flow to a certain extent, extending the service life of the cable and the cable outer insulation component 5.

[0053] In this embodiment, to ensure the insulation performance of the insulation protection structure, in addition to the arc-shaped protective shell 1 being made of insulating material, the insulation protection structure also includes an insulating component 5. Further, the insulating component 5 includes an outer sheath, an armor layer, and an inner liner. The outer sheath is disposed between the arc-shaped heat insulation layer 4 and the cable, the armor layer is disposed between the outer sheath and the cable, and the inner liner is disposed between the armor layer and the cable. The outer surface of the cable is sequentially wrapped with the inner liner, the armor layer, and the outer sheath. The main function of the inner liner is to prevent corrosion of the cable's inner sheath. The function of the armor layer is to reduce the impact of mechanical forces on the cable; the mechanical forces applied to the cable are borne by the armor layer. The function of the outer sheath is to prevent the armor layer from being eroded. This layered design achieves multiple layers of protection, improving the overall reliability and safety of the protection.

[0054] In this embodiment, the material of the insulating component 5 can be any of those known to those skilled in the art, provided that multiple protections are achieved. In one example of this utility model, the inner lining layer is made of industrial non-woven fabric, the armor layer is made of steel wire or steel strip, and the outer sheath layer is made of polyethylene.

[0055] Through the above technical solution, this utility model provides a cable welding insulation protection structure. Two sets of arc-shaped protective shells are sleeved on the outside of the cable, and splicing components are set at the junction of the two sets of arc-shaped protective shells. The two sets of arc-shaped protective shells are connected by the interlocking of the hollow part of the connecting strip and the splicing column of the connecting post, realizing the rapid installation and disassembly of the protective shells. Furthermore, a pure aluminum reflective film, an arc-shaped heat insulation layer, and an insulating component are added between the protective shell and the cable, further reducing heat loss and blocking high-temperature conduction. This utility model takes into account both sealing performance and stability, allowing the cable to maintain its performance over a wide temperature range, adapting to various environmental conditions, extending the service life of the cable, effectively reflecting and reducing heat generated by solar radiation or other heat sources, and reducing the rate of performance degradation or damage to the cable and insulation protection structure caused by high temperatures.
