Description

Anti-extrusion and flame-retardant cable

Technical Field

The utility model relates to a cable field specifically is an anti extrusion and fire-retardant cable.

Background

Cable is a generic term for optical cables, electrical cables, and the like. The cable has many purposes, is mainly used for controlling installation, connecting equipment, transmitting power and other multiple functions, and is a common and indispensable object in daily life.

Cable among the prior art still has the following problem, receives when rolling of external great power in the use when the cable, inside fibre core is breakable, and its anti extruded performance is low, and the fire-retardant performance of preventing fires is low, and joint strength between the inside key layer of cable is not enough simultaneously, easily leads to the superior performance decline of cable, and life is short.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an anti extrusion and fire-retardant cable to solve the problem that proposes in the above-mentioned background art.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides an anti extrusion and fire-retardant cable, includes sinle silk group, interior protective sheath and outer protective sheath from inside to outside, the sinle silk that the sinle silk group set up including the interval and fill the flexbile layer between the sinle silk, interior protective sheath is from inside to outside including fire-retardant layer, internal insulation layer and first elastic layer, the internal insulation layer includes insulating waterproof layer and insulating ageing resistance layer, first elastic layer includes the elastic ball that the interval set up and fills the second elastic layer between the elastic ball, outer protective sheath includes the embedded elastic bead on the external insulation layer in external insulation layer and interval.

And connecting blocks are arranged between the insulating waterproof layer and the insulating anti-aging layer at intervals.

Compared with the prior art, the utility model discloses the beneficial effect who reaches is:

1. the utility model discloses molded lines core group includes the sinle silk that the interval set up and fills the flexible layer between the sinle silk, and the flexible layer can play the effect of protection to the sinle silk, unloads external force buffering, and protection sinle silk in the at utmost does not receive the influence of external force, further improves the anti extrusion performance of cable.

2. The inner protective sleeve of the utility model comprises a flame-retardant layer, an inner insulating layer and an elastic layer from inside to outside, which can realize the effects of flame retardance, insulation and compression resistance and ensure the normal use of the cable under various external environments; the inner insulating layer comprises an insulating waterproof layer and an insulating anti-aging layer, so that waterproof and anti-aging effects can be realized, the performance of the cable is further improved, the cable can be normally used in more severe environments without influencing the inner wire core, and the connecting blocks are arranged between the insulating waterproof layer and the insulating anti-aging layer at intervals, so that the connecting strength between the two layers can be improved, and the superior performance of the cable is ensured; the elastic layer includes the elastic ball that the interval set up and fills the elastic layer between the elastic ball, can cushion the pressure that outside produced, and more external forces can be offset off to the elastic ball, and then reach the protection to the inner protective sheath.

3. The outer protective sheath includes that outer insulating layer and interval embed the elasticity pearl on the outer insulating layer, and the elasticity pearl can carry out first buffering with external force, prevents that external force is too big direct to the inside production effect of cable, can make cable body and ground have certain distance simultaneously, prevents that the moist moisture on ground and high temperature from to the influence of cable body, having prolonged the life of cable.
