Description

Technical Field

[0001] The utility model relates to the technical field of waterproof cables, in particular to a multi-core waterproof and anti-corrosion cable. Background Technique

[0002] Electric wires and cables are wire products used to transmit electrical energy, information and realize the conversion of electromagnetic energy. In a broad sense, electric wires and cables are also simply referred to as cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as: an aggregate composed of the following parts, one or more insulated wire cores, and their respective possible coating layers, general protective layer and outer protective layer. A cable can also have additional uninsulated conductors. However, existing cables are relatively lacking in terms of waterproofing and anti-corrosion, greatly reducing their service life. Existing patent documents have made improvements in this regard.

[0003] Such as Chinese Patent CN209962746U, a multi-core waterproof and anti-corrosion cable, which relates to the technical field of multi-core cables, in particular to a multi-core waterproof and anti-corrosion cable, including an outer layer. An inner layer is provided inside the outer layer, a waterproof layer is fixedly connected to the outer surface of the inner layer, an anti-corrosion layer is fixedly connected to the outer surface of the waterproof layer, the anti-corrosion layer includes an anti-corrosion outer lining layer, an anti-corrosion middle layer and an anti-corrosion inner lining layer, and a gap is left between the anti-corrosion outer lining layer and the anti-corrosion middle layer. In this multi-core waterproof and anti-corrosion cable, through the setting of the waterproof layer, it is prevented that water directly contacts the wires inside the cable, affecting its normal operation, and in severe cases, it may cause damage to it, extending the service life and achieving the purpose of waterproofing. Through the setting of the anti-corrosion layer, the purpose of anti-corrosion is achieved.

[0004] Although the equipment in the above document can effectively protect the inside of the electric wire, it still has obvious defects in actual use, such as:

[0005] When the cable is buried underground, in most cases, it will be resisted by hard objects such as stones. As the soil compacts, the stones will cause scratches on the surface of the cable, and at the same time, multiple internal protective layers will also be damaged. This cable does not have a function setting for surface protection and cannot protect the cable more comprehensively;

[0006] Therefore, a multi-core waterproof and anti-corrosion cable that can improve the protection performance is now designed to solve such defects. Content of the Utility Model

[0007] In view of the deficiencies of the prior art, the utility model provides a multi-core waterproof and anti-corrosion cable, which solves the problem that existing cables are easily damaged by external objects.

[0008] To achieve the above object, the present utility model is realized through the following technical solutions: A multi-core waterproof and anti-corrosion cable, including an insulating sleeve located inside a rubber outer sheath. Inside the insulating sleeve, a plurality of core bodies are installed, and the core bodies are provided with a filling layer that is used in cooperation with the core bodies and is in close contact with the core bodies.

[0009] Preferably, an inner anti-corrosion layer is installed on the surface of the insulating sleeve. A support ring cylinder is sleeved on the surface of the inner anti-corrosion layer, and a plurality of support ring cylinders are provided. An outer anti-corrosion layer is provided on the surface of the support ring cylinder.

[0010] Preferably, a toothed ring that is used in cooperation with the outer anti-corrosion layer is fixedly connected to the surface of the support ring cylinder, and a plurality of toothed rings are provided.

[0011] Preferably, an arc-shaped winding groove is formed on the surface of the rubber outer sheath, and a steel wire is installed inside the arc-shaped winding groove.

[0012] Preferably, both the inner anti-corrosion layer and the outer anti-corrosion layer are anti-static gas-phase rust-proof films.

[0013] Preferably, the filling layer is soft polyvinyl chloride small particles.

[0014] Beneficial effects

[0015] The present utility model provides a multi-core waterproof and anti-corrosion cable. Compared with the existing technologies, it has the following beneficial effects:

[0016] (1). For this multi-core waterproof and anti-corrosion cable, by forming an arc-shaped winding groove on the surface of the rubber outer sheath and providing a steel wire inside the arc-shaped winding groove, and the winding spacing of the steel wire is relatively close. The setting of this structure can use the winding of the steel wire to protect the surface of the rubber outer sheath, avoiding damage to the rubber outer sheath caused by large solid objects with cutting force such as large stones. Coupled with the inner anti-corrosion layer and the outer anti-corrosion layer, it can effectively protect the core body from waterproofing and anti-corrosion, meeting the current use requirements.

[0017] (2). For this multi-core waterproof and anti-corrosion cable, by installing a support ring cylinder between the inner anti-corrosion layer and the outer anti-corrosion layer and installing a toothed ring on the surface of the support ring cylinder, the settings of these structures can effectively fit the inner anti-corrosion layer and the outer anti-corrosion layer to the insulating sleeve and the rubber outer sheath respectively, and can prevent accumulation and wrinkles, improving the stability of the internal structure and effectively extending the service life.
