Abstract

The invention relates to a novel compression-resistant, deformation-resistant and wear-resistant cable which comprises wire cores, a shielding layer, a flame-retardant layer, an armor layer and a wear-resistant outer cladding layer, wherein the shielding layer, the flame-retardant layer, the armor layer and the wear-resistant outer cladding layer are sequentially coated outside the wire cores from inside to outside, a plurality of wire cores are uniformly distributed on the circumference of each wire core, and a toughness framework for separating and fixing adjacent wire cores for enhancing the deformation-resistant capacity of the cable is arranged in. On the basis of the existing cable, the tough framework with the spacer strip and the arc inclusion strip is additionally arranged at the center of the cable to inclusion and fix the wire core, and when the wire core is extruded from the outside, the tough framework plays a role in absorbing and buffering extrusion force, so that the deformation prevention capability of the cable is enhanced; secondly, through the armor layer that forms around the package by the steel wire of high strength, strengthened the compressive capacity of cable greatly, and then avoided the cable to receive the damage easily, improved the life of cable.

Description

Novel compression-resistant anti-deformation wear-resistant cable

Technical Field

The invention relates to the technical field of cables, in particular to a novel compression-resistant, deformation-resistant and wear-resistant cable.

Background

With the continuous development and expansion of the scale of industries such as the Chinese power industry, the communication industry, the traffic industry and the like, the requirements on cables are also continuously improved. After the cable is extruded by external force in the using process, the filling material in the cable can be extruded and deformed and is difficult to restore to the original shape, and meanwhile, the cable core of the cable is extremely easy to damage during the extrusion by the external force, so that the cable is damaged, and the service life of the cable is shortened.

Disclosure of Invention

In order to solve the technical problems, the invention provides a novel compression-resistant, deformation-resistant and wear-resistant cable.

The technical problem to be solved by the invention is realized by adopting the following technical scheme:

novel resistance to compression wear-resisting cable of preapring for an unfavorable turn of events shape, including sinle silk, from interior to exterior in proper order the cladding at outside shielding layer, fire-retardant layer, armor, the wear-resisting surrounding layer of sinle silk, sinle silk circumference equipartition has a plurality of, and the center department of cable is equipped with and separates adjacent sinle silk and fixes its toughness skeleton in order to be used for reinforcing the cable anti-deformation ability.

Further, the toughness skeleton includes the toughness skeleton main part that sets up in cable center department, distributes along toughness skeleton main part circumference and is used for the frame strip that separates adjacent sinle silk.

Furthermore, arc-shaped inclusion strips which are bent along the same direction and used for fixing the wire cores are arranged at the end parts of the spacer strips.

Further, the armor layer is a high-strength steel wire wrapping tape.

The invention has the beneficial effects that:

on the basis of the existing cable, the tough framework with the spacer strip and the arc inclusion strip is additionally arranged at the center of the cable to inclusion and fix the wire core, and when the wire core is extruded from the outside, the tough framework plays a role in absorbing and buffering extrusion force, so that the deformation prevention capability of the cable is enhanced; secondly, through the armor layer that forms around the package by the steel wire of high strength, strengthened the compressive capacity of cable greatly, and then avoided the cable to receive the damage easily, improved the life of cable.

Drawings

The invention is further illustrated with reference to the following figures and examples:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural diagram of a ductile skeleton according to the present invention.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained in the following with the accompanying drawings and the embodiments.

As shown in fig. 1, the novel compression-resistant deformation-resistant wear-resistant cable comprises a wire core 1, and a shielding layer 3, a flame-retardant layer 4, an armor layer 5 and a wear-resistant outer cladding layer 6 which are sequentially coated outside the wire core from inside to outside. The cable core 1 is composed of a copper conductor and an insulating sleeve coated outside the copper conductor, the armor layer 5 is formed by winding a high-strength steel wire wrapping tape, and the armor layer 5 and an inner coating layer form a compression-resistant combination body so as to improve the compression resistance of the cable.

The utility model discloses a cable, including sinle silk 1, the center department of cable is equipped with the toughness skeleton 2 that separates adjacent sinle silk 1 and fix it in order to be used for reinforcing the cable to prevent deformation ability, toughness skeleton 2 adopts elastic insulation rubber material to process into shape through the integrative technology of moulding plastics.

As shown in fig. 2, toughness skeleton 2 is including the toughness skeleton main part 21 that is located cable center department, the equipartition has six and is used for the shelf strip 22 that separates adjacent sinle silk 1 on the periphery of toughness skeleton main part 21, all be equipped with on the tip of six shelf strips 22 along the arc inclusion strip 23 of same clockwise bending, can fix sinle silk 1 between adjacent shelf strip 22 through arc inclusion strip 23, the fixed effect of inclusion has been played, when external extrusion simultaneously, shelf strip 22 can receive the extrusion force earlier, and transmit toughness skeleton main part 21 with the extrusion force on, avoided the extrusion force to extrude sinle silk 1 on, thereby lead to the cable damage.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
