Abstract

The utility model relates to a cable sheath comprising a sheath layer wrapping a cable core, wherein the sheath layer is spirally wrapped by a reflective tape, and the sheath layer spirally wrapped by the reflective tape is wrapped by a transparent sheath; and the transparent sheath is made of thermoplastic polyurethane rubber sheath. The cable sheath has the advantages that the color of the external surface of the cable takes the shape of striature so as to be easy to be identified and distinguished from ambient environment, thereby preventing the cable from being grinded and damaged by passing vehicles; due to the arrangement of the reflective tape, the cable is provided with a reflective layer so that the cable can be easily identified at night or under the environment with dim light, thereby preventing the cable from being grinded and damaged by the passing vehicles and greatly reducing the rate of damage of the cable; and the transparent sheath is made of the thermoplastic polyurethane rubber sheath so that the higher corrosion resistance and toughness of polyurethane materials can be utilized for reducing the rate of damage caused by the reciprocating movement of the cable used as a traveling cable, thereby prolonging the service life and reducing the risk of damage.

Description

A kind of cable cover(ing)

Technical field

The utility model relates to a kind of jacket structure, especially a kind of cable cover(ing).

Background technology

Domestic existing cable cover(ing), color in particular for the cable cover(ing) of minings such as colliery all is made up of single color, as black, yellow or redness etc., the shortcoming of this kind cable cover(ing) is to make cable in mine uses such as colliery, be not easy to make a distinction, can often suffer passing haulage vehicle to roll and damage with on every side environmental colors; Simultaneously because cable cover(ing) does not have reflector layer, when night or light are faint, be subjected on every side rolling of vehicular traffic especially easily and damage.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of cable cover(ing), can solve the cable identification problem, overcome the shortcoming of existing cable sheath, easily distinguish with environment on every side, when night or light are faint, distinguish easily, greatly reduce the damage probability.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of cable cover(ing), comprise being wrapped in the outer restrictive coating of cable conductor, and the restrictive coating external spiral is surrounded with reflective tape, and the restrictive coating of the wrapped reflective tape of spiral is wrapped with transparent sheath.

The thickness of reflective tape is 25～30 μ m.

The wrapped band gap of reflective tape is 30～60%.

Transparent sheath is the thermoplastic polyurethane rubber sheath.

The thickness of thermoplastic polyurethane rubber sheath is 0.5～1.2mm, and Shore hardness is at 60～65A.

The cable cover(ing) that the utility model provides, because after the existing restrictive coating external spiral that is wrapped in outside the cable conductor is surrounded with reflective tape, wrap up transparent sheath again, thereby make the color of outer surface of cable be striated, identification easily, easily distinguish, avoid rolling of vehicular traffic and damage with environment on every side; Simultaneously the cable that is arranged so that of reflective tape has had reflector layer, distinguishes easily when night or light are faint, avoids rolling of vehicular traffic and damages; Greatly reduce the damage probability of cable; Transparent sheath adopts the thermoplastic polyurethane rubber sheath, has utilized higher resistance to wear of polyurethane material and toughness, because of the damaged probability that moves around, has prolonged useful life in the time of can reducing the cable quilt as the removal cable use, has reduced the damage risk.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a left view of the present utility model.

Embodiment

As depicted in figs. 1 and 2, the utility model comprises the restrictive coating 2 that is wrapped in outside the cable conductor 1, and restrictive coating 2 external spirals are surrounded with reflective tape 3, and the restrictive coating 2 of the wrapped reflective tape 3 of spiral is wrapped with transparent sheath 4.

The thickness of reflective tape 3 is 25～30 μ m.

Reflective tape 3 wrapped band gaps are 30～60%.

Transparent sheath 4 is the thermoplastic polyurethane rubber sheath.

Manufacture process of the present utility model is as follows:

At first, extrude the restrictive coating 2 of solid color in cable conductor 1 outside, at the wrapped layer thickness of the restrictive coating 2 external spirals reflective tape 3 that is 25～30 μ m, the band gap of wrapped reflective tape 3 is 30～60%, and then extrude the transparent thermoplastic polyurethane rubber sheath that a layer thickness is 0.5～1.2mm, the reflective tape 3 of any color can make up with the restrictive coating 2 of different colours, forms different types of striped recognition effect.
