[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Cable is usually a rope-like cable made of several or several groups of wires twisted together. 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. When the wires and cables are in the state of being transported and dragged along the ground, it will cause more or less wear on the outside of the cable.

[0003] The utility model with announcement number CN218866764U discloses a fire-resistant and moisture-proof cable, including mutually wound and insulated wire cores and an outer layer arranged outside the wire cores, the outer layer including a wear-resistant layer, a moisture-proof layer, a fire-proof layer, an anti-tensile layer and a protective layer arranged in sequence from the outside to the inside, the protective layer including a rubber layer, and an inner film layer is arranged between the rubber layer and the wire core.

[0004] In the process of implementing this application, it was found that the technology has the following problems: in the above patent documents, the cable is mainly protected by the polyurethane moisture-proof paint of the moisture-proof layer. When the cable encounters a sharp object that pierces the wear-resistant layer and the moisture-proof layer, the inside of the cable may be affected by water seepage or water vapor, and the overall waterproof structure is relatively simple.

[0005] For this reason, a moisture-proof and wear-resistant cable is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a moisture-proof and wear-resistant cable in order to provide multiple waterproof protections for the cable, prevent the cable from being short-circuited due to water immersion, and improve the waterproof effect of the cable.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A moisture-proof and wear-resistant cable, comprising a polyethylene jacket, a rubber pressure-resistant layer fixedly connected to the inner surface of the polyethylene jacket, a waterproof layer arranged on a side of the rubber pressure-resistant layer away from the polyethylene jacket, a PE waterproof layer arranged on a side of the waterproof layer away from the rubber pressure-resistant layer, the interior of the PE waterproof layer is filled with waterproof grease, and a cable core mechanism and a supporting mechanism are arranged inside the waterproof grease;

[0010] Furthermore, the supporting mechanism is located in the middle of the waterproof grease, the number of the cable core mechanisms is four, and the four cable core mechanisms are arranged around the supporting mechanism.

[0011] Furthermore, the cable core structure includes a copper tape shielding layer, an insulating shielding layer is arranged on the inner surface of the copper tape shielding layer, and a conductor is arranged inside the insulating shielding layer.

[0012] Furthermore, the supporting mechanism comprises a rubber insulating sleeve, and an inner surface of the rubber insulating sleeve is fixedly connected with an inner steel wire reinforcement rib.

[0013] Furthermore, external steel wire reinforcement ribs are arranged inside the polyethylene outer jacket.

[0014] Furthermore, the number of the external steel wire reinforcement ribs is four, and the four external steel wire reinforcement ribs are equidistantly arranged inside the polyethylene outer jacket.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] 1. In the utility model, when the polyethylene jacket and the rubber pressure-resistant layer of the cable are damaged, the waterproof canvas layer inside the polyethylene jacket has good mildew resistance and waterproofness, which prevents water stains from flowing into the cable and affecting the use of the cable; and when the waterproof canvas layer is damaged, the aluminum-plastic composite belt layer with good waterproofness can also prevent water from radially entering the cable; on the other hand, the PE waterproof layer is also a high-density polyethylene, which has the characteristics of being waterproof, moisture-proof, and resistant to acid and alkali corrosion. When the waterproof layer is damaged, the PE waterproof layer can further block the water vapor overflowing into the cable; the mineral oil and wax in the waterproof ointment inside the polyethylene jacket have waterproof properties, which can effectively prevent the penetration of water molecules. When the PE waterproof layer is also damaged, the cable core mechanism can still be waterproofed; through the cooperation of the above structures, the cable can be provided with multiple waterproof protections to prevent the cable from being short-circuited due to water immersion, thereby improving the waterproof effect of the cable.

[0017] 2. In the utility model, the polyethylene high molecular weight in the polyethylene sheath outside the cable is wear-resistant and low-friction, ensuring the overall wear resistance of the cable, and the external steel wire reinforcement inside the polyethylene sheath can improve the overall strength and tensile resistance of the cable. At the same time, it can provide good support for the cable in conjunction with the supporting mechanism inside the cable to prevent excessive bending of the cable, and the rubber pressure-resistant layer has good flexibility and can withstand a certain amount of pressure, thereby providing better protection for the cable.
