Abstract

The invention relates to an anti-deformation communication cable which comprises a cable outer cover, wherein a first filling layer is arranged in the cable outer cover, a plurality of first wire cores which are circumferentially distributed around the rotation center of the cable outer cover are arranged in the first filling layer, a plurality of wire core units which are circumferentially distributed around the rotation center of the cable outer cover are arranged in the cable outer cover, and a supporting area which is used for enhancing the bearing capacity of the cable outer cover and limiting the positions of the wire core units is arranged between every two adjacent wire core units. The position of the wire core unit is limited by the supporting area, and meanwhile, the bearing capacity of the second filling layer is improved by the supporting area, so that the first wire core and the second wire core are protected.

Description

Anti-deformation communication cable

Technical Field

The invention relates to the field of cable production and processing, in particular to an anti-deformation communication cable.

Background

Along with the automation level is higher and higher, large-scale electric automation equipment is applied to various factories and mines, in order to ensure that the internal communication and operation in the mine are normal, a large number of communication cables need to be laid, the mine environment is complex, workers often trample the communication cables, and engineering vehicles roll the communication cables, so that the communication cables are often damaged and broken, the normal operation of the communication cables cannot be influenced, the traditional communication cables cannot adapt to the complex environment, the bearing capacity is poor, the communication cables are easy to damage and break, and the deformation-resistant communication cables are provided for improving the reliability of the cables to solve the problems.

Disclosure of Invention

In order to solve the above technical problems, the present invention provides a communication cable with deformation resistance. The technical problem to be solved by the invention is realized by adopting the following technical scheme:

the utility model provides a communication cable of resistance to deformation, includes the cable dustcoat, be equipped with the filling layer in the cable dustcoat, be equipped with a plurality of wire core that is the circumference and distributes around cable dustcoat center of rotation in the filling layer, be equipped with the support area that is equipped with reinforcing cable dustcoat bearing capacity and restriction wire core unit position around a plurality of wire core unit, two adjacent wire core units that are the circumference and distribute around cable dustcoat center of rotation in the cable dustcoat.

The cable core unit comprises second-line cores symmetrically distributed in the radius direction of the cable housing, and a protective layer for preventing the second-line cores from being broken is sleeved on the second-line cores.

The two sides of the supporting area, which are distributed in parallel along the radius direction of the cable cover, are concentrically distributed with the cable cover, and the two opposite sides are concentrically distributed with the outline of the corresponding wire core unit.

The cable is characterized in that a fireproof layer is distributed in the cable outer cover, and a shielding layer is distributed in the fireproof layer.

And a second filling layer is arranged between the wire core unit and the first filling layer.

The invention has the beneficial effects that: the position of the wire core unit is limited by the supporting area, and meanwhile, the bearing capacity of the second filling layer is improved by the supporting area, so that the first wire core and the second wire core are protected.

Drawings

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

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

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be described more clearly and more completely with reference to the drawings in the following embodiments, and it is understood that the described embodiments are only a part of the present invention, rather than all of the present invention, and based on the embodiments, other embodiments obtained by those skilled in the art without inventive exercise are within the protection scope of the present invention.

As shown in fig. 1, a communication cable of resistance to deformation, including cable dustcoat 1, be equipped with a filling layer 5 in the cable dustcoat 1, be equipped with a plurality of wire core 2 that is the circumference distribution around cable dustcoat 1 rotation center in the filling layer 5, be equipped with in the cable dustcoat 1 around being a plurality of wire core unit 3 that the circumference distributes around cable dustcoat 1 rotation center, be equipped with between two adjacent wire core unit 3 reinforcing cable dustcoat 1 bearing capacity and restriction wire core unit 3 position's supporting area 4.

The core unit 3 includes the second core 31 along the radial direction symmetric distribution of cable dustcoat 1, second core 31 cover is equipped with and prevents the cracked protective layer 32 of second core 31.

The two sides of the supporting area 4, which are distributed in parallel along the radius direction of the cable housing 1, are concentrically distributed with the cable housing 1, and the two opposite sides are concentrically distributed with the corresponding line core unit 3 to limit the position of the line core unit 3 and prevent the line core unit 3 from shifting when receiving pressure; the arc lengths of two sides of the supporting area 4 concentrically distributed with the cable housing 1 are gradually increased along the radius direction of the cable housing 1; two sides of the supporting area 4, which are not concentrically distributed with the cable housing 1, are concentrically distributed with a second wire core 31 in the wire core unit 3.

A fireproof layer 6 is distributed in the cable housing 1, and a shielding layer 7 is distributed in the fireproof layer 6.

A second filling layer 8 is arranged between the wire core unit 3 and the first filling layer 5; the bearing capacity of the first filling layer 5 and the shielding layer 7 is enhanced on two side edges of the supporting area 4 concentrically distributed with the cable housing 1, and the first filling layer 5 and the shielding layer 7 are prevented from excessively deforming and damaging the first wire core 2 and the second wire core 31 due to overlarge external pressure.

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.
