Technical Field

[0001] The utility model relates to the technical field of cable protective sleeves, in particular to an aging-resistant cable protective sleeve. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating covering. Cables have the characteristics of internal power supply and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and an insulating layer, and are used to connect circuits, electrical appliances, etc.

[0003] A cable insulation protective cover is disclosed in a Chinese utility model patent with publication number CN219626340U, including a cable protective cover, a first corrosion-resistant layer is arranged on the outer side of the inner part of the cable protective cover, a second corrosion-resistant layer is arranged on the inner side of the first corrosion-resistant layer, a first insulating layer is arranged on the inner side of the second corrosion-resistant layer, a flame-retardant layer is arranged on the inner side of the first insulating layer, a high-temperature resistant layer is arranged on the inner side of the flame-retardant layer, a heat dissipation layer is arranged on the inner side of the high-temperature resistant layer, a heat-conducting layer is arranged on the inner side of the heat-dissipating layer, a second insulating layer is arranged on the inner side of the heat-conducting layer, a cable storage hole is opened on the cable protective cover, an anti-slip pad is fixedly arranged on the inner wall of the cable storage hole, and a cable storage groove is opened inside the cable protective cover.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device protects the cable by setting a cable protective cover on the outside of the first corrosion-resistant layer. After a period of use, the cable protective cover is prone to wear. At this time, the staff can extend the service life of the cable by replacing the cable protective cover. However, in actual operation, it is difficult to detect the degree of wear of the cable protective cover. The staff needs to use tools such as calipers to measure the thickness of the cable in order to judge the wear of the cable protective cover. In most cases, the degree of wear of different positions of the cable is different, which is not conducive to improving the user experience of the staff. Utility Model Content

[0005] In order to solve the above problems, the utility model provides an aging-resistant cable protective cover.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: an aging-resistant cable protective cover, comprising three cable bodies, a first protective layer is commonly installed on the side walls of the three cable bodies, a filling layer is arranged on the inner wall of the first protective layer, a first insulating layer is arranged on the side wall of the first protective layer, a fluorescent layer is arranged on the side wall of the first insulating layer, and a second protective layer is arranged on the side wall of the fluorescent layer.

[0007] By adopting the above technical solution, after the cable has been used for a period of time, the outermost second protective layer is prone to wear and tear. The staff only needs to illuminate the second protective layer with a flashlight when leaving get off work every day to detect the wear and tear of the second protective layer. When the second protective layer in the area illuminated by the flashlight is severely worn, the thickness of the second protective layer there is relatively small, and the light can directly pass through the second protective layer and contact the fluorescent layer, thereby generating fluorescence. At this time, the staff only needs to observe whether the area illuminated by the flashlight generates fluorescence to roughly judge the degree of wear of the second protective layer, thereby reducing the difficulty for the staff to detect the second protective layer.

[0008] Furthermore, the fluorescent layer includes a transparent protective layer arranged on the side wall of the first insulating layer and a fluorescent powder layer arranged in the transparent protective layer.

[0009] By adopting the above technical solution, when the staff replaces the second protective layer, the transparent protective layers on both sides of the phosphor layer protect the phosphor layer, thereby reducing the probability of damage to the phosphor layer when the staff replaces the second protective layer, thereby improving the staff's user experience.

[0010] Furthermore, the transparent protective layer is made of silica gel.

[0011] By adopting the above technical solution, the silica gel is a transparent solid with a soft texture. The transparent protective layer made of silica gel is a transparent solid, which can protect the phosphor layer and transmit light, thereby helping to extend the service life of the cable.

[0012] Furthermore, a tin foil layer is provided between the first protective layer and the first insulating layer, and the tin foil layer is wound around the side wall of the first protective layer.

[0013] By adopting the above technical solution, the probability of cable signal interference is reduced, which is beneficial to improving the user experience of the staff.

[0014] Furthermore, a steel belt armor layer is provided between the first insulating layer and the transparent protective layer.

[0015] By adopting the above technical solution, the structural strength of the cable is improved, thereby reducing the probability of irreversible deformation of the cable when subjected to external force, thereby increasing the service life of the cable.

[0016] Furthermore, the first insulating layer is made of Teflon.

[0017] By adopting the above technical solution, polytetrafluoroethylene, abbreviated as PTFE, also known as Teflon, commonly known as the "King of Plastics", is a high molecular polymer prepared by polymerization of tetrafluoroethylene as a monomer. It has excellent chemical stability, corrosion resistance, sealing, high lubricity and non-stickiness, electrical insulation and good anti-aging resistance, which is beneficial to improve the use experience of the cable.

[0018] Furthermore, a second insulating layer is provided between the first insulating layer and the tin foil layer.

[0019] Furthermore, the second insulating layer is made of silicone rubber.

[0020] By adopting the above technical solution, silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and the silicon atom is usually connected to two organic groups. Ordinary silicone rubber is mainly composed of silicon-oxygen chain segments containing methyl and a small amount of vinyl. Silicone rubber has excellent insulation properties, and its corona resistance and arc resistance are also very good. The cooperation between the second insulation layer and the first insulation layer can help improve the insulation effect of the cable protective sheath, thereby improving the use experience of the cable.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, after the cable has been used for a period of time, the outermost second protective layer is prone to wear. The staff only needs to illuminate the second protective layer with a flashlight when leaving get off work every day to detect the wear of the second protective layer. When the second protective layer in the area illuminated by the flashlight is severely worn, the thickness of the second protective layer there is relatively small, and the light can directly pass through the second protective layer and contact the fluorescent layer, thereby generating fluorescence. At this time, the staff only needs to observe whether the area illuminated by the flashlight generates fluorescence to roughly judge the degree of wear of the second protective layer, thereby reducing the difficulty for the staff to detect the second protective layer;

[0023] 2. In this application, when the staff replaces the second protective layer, the transparent protective layers on both sides of the phosphor layer protect the phosphor layer, thereby reducing the probability of damage to the phosphor layer when the staff replaces the second protective layer, thereby improving the staff's use experience;

[0037] The second insulating layer 8 is arranged between the first insulating layer 3 and the tin foil layer 6, and the second insulating layer 8 is made of silicone rubber. Silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and the silicon atom is usually connected to two organic groups. Ordinary silicone rubber is mainly composed of silicon oxygen chain segments containing methyl and a small amount of vinyl. Silicone rubber has excellent insulation properties, and its corona resistance and arc resistance are also very good. The cooperation between the second insulating layer 8 and the first insulating layer 3 can help improve the insulation effect of the cable protective sheath, thereby improving the use experience of the cable.

[0038] The use principle of an aging-resistant cable protective cover in this embodiment is as follows: after a period of use, the outermost second protective layer 5 is prone to wear. The staff only needs to illuminate the second protective layer 5 with a flashlight when leaving get off work every day to detect the wear of the second protective layer 5. When the second protective layer 5 in the area illuminated by the flashlight is severely worn, the thickness of the second protective layer 5 there is small, and the light can directly pass through the second protective layer 5 and contact with the fluorescent layer 4, thereby generating fluorescence. At this time, the staff only needs to observe whether the area illuminated by the flashlight generates fluorescence to roughly judge the degree of wear of the second protective layer 5, thereby reducing the difficulty for the staff to detect the second protective layer 5.
