Description

Cable easy to store

Technical Field

The utility model belongs to the technical field of cables, and particularly relates to an easy cable.

Background

A cable is an electrical energy or signal transmission device, usually a rope-like cable made up of several or groups of conductors (at least two in each group) twisted together, each group being insulated from the other and often twisted around the center, the whole being covered with a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. Ordinary electric wires become rigid in cold regions such as the hokkaido, and if they are stored forcibly, they will cause some damage.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an easy-to-store cable which is easy to store in a cold region.

According to an aspect of the present invention, there is provided an easy-to-store cable, including:

the conductor is formed by stranding and pressing a plurality of bare copper wires, and the number of the conductors is two;

the insulating layer is coated outside the conductors to form cable cores, and the two cable cores are arranged in a tangent mode;

the fiber yarn is provided with two strands, the two strands of fiber yarns are distributed on two sides of the cable core, and each strand of fiber yarn is tangent to the cable core;

and the outer tegument layer is coated outside the cable core and the fiber yarns and is made of a low-temperature elastomer flexible material.

In some embodiments, the conductor is formed by stranding and compacting a plurality of bare copper wires with the diameter of 0.12 mm.

In some embodiments, the conductor has an S-direction twisting direction, and the conductor has a twisting pitch of 32mm or less.

In some embodiments, each of the fiber filaments is formed by twisting four fibers, and each of the fibers has a linear density of 1000D.

In some embodiments, the material of the outer layer is nitrile rubber/polyvinyl chloride blend rubber.

The beneficial effects are as follows: the conductor is formed by twisting the thin bare copper wires with a large number, so that the softness of the conductor can be increased, and the softness of the cable can be increased; the outer layer of the cable is made of low-temperature elastomer flexible materials, so that the cable can easily keep flexibility in a low-temperature state; the pitch of the cable is small, so that the flexibility and the winding resistance of the cable can be increased; the 1000D fiber yarn with the tensile structure is added, so that the overall strength and the winding resistance of the cable can be improved; the cable core and the fiber yarns are arranged in a tangent mode, so that the thickness of the outer tegument layer can be guaranteed to be thick under the condition that the overall diameter of the cable is small, and the flexibility of the overall cable is improved. The cable provided by the utility model can be kept soft in cold regions, is easy to store, has certain strength, and does not crack in cold and winding environments.

Fig. 1 is a schematic cross-sectional view of an easy-to-store cable according to an embodiment of the present invention.

Detailed Description

Fig. 1 schematically illustrates an easy-to-store cable according to an embodiment of the present invention. As shown in fig. 1, the easy-to-store cable includes a sheath layer 1, an insulating layer 2, a conductor 3, and a fiber filament 4.

Two conductors 3 are provided. Each conductor 3 is formed by stranding and compressing a plurality of bare copper wires. In this embodiment, the conductor 3 is formed by twisting and compressing 67 bare copper wires having a diameter of 0.12 mm. The flexibility of the cable is increased by using a plurality of bare copper wires with thin diameters to twist and compress the conductor 3. The direction of twist of the conductor 3 is the S direction, and the pitch of twist of the conductor 3 is not more than 32 mm. The reduction of the stranding pitch increases the flexibility and the winding resistance of the cable. The conductor 3 is coated with the insulating layer 2 to form a cable core. The cable core is provided with two. The two cable cores are arranged in a tangent mode. The insulating layer 2 is made of polyvinyl chloride. The fiber yarn 4 is provided with two strands, and each strand of the fiber yarn 4 is formed by twisting four fibers. The stranding direction of each fiber filament is S direction, and the stranding pitch of each fiber filament 4 is less than or equal to 47 mm. The linear density of each fiber was 1000D. Two strands of fiber yarns 4 are distributed on two sides of the two cable cores. Each fiber 4 is respectively tangent with the two cable cores. This ensures that the diameter of the entire cable is kept as small as possible, while the thickness of the outer layer 1 is as large as possible. The insulating layer 2 and the fiber yarn 4 are externally covered with the outer covering layer 1. The outer layer 1 is made of low-temperature elastic flexible material. The cable can keep enough flexibility under the low-temperature environment. In this embodiment, the material of the outer layer 1 is nitrile rubber/polyvinyl chloride blend rubber. The nitrile rubber/polyvinyl chloride blended rubber is prepared by blending nitrile rubber and polyvinyl chloride. The outer layer 1 is thick. During manufacturing, the insulation thickness is poor. In conventional fabrication, the thickness of the outer layer is 8.95 ± 0.2 mm. In this embodiment the thickness of the outer layer 1 is 9.15mm, thereby increasing the softness of the cable.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
