Anti-twisting cable with high mechanical strength

Abstract

The invention discloses an anti-twisting cable with high mechanical strength. The anti-twisting cable with the high mechanical strength comprises an outer protecting jacket (1), an inner protecting jacket (3), cable protecting jackets (4) and cable cores (5), wherein the inner surface of the outer protecting jacket (1) is provided with a plurality of grooves A; the outer surface of the inner protecting jacket (3) is provided with grooves B corresponding to the grooves A one to one; the grooves A cooperate with the grooves B to form cavities; reinforcements (2) are mounted in the cavities; the outer side of the outer protecting jacket (1) is provided with an armoring layer (8); the outer side of the armoring layer (8) is coated with a cooling coating layer; a central reinforcement (9) is arranged in the inner protecting jacket (3). The anti-twisting cable with the high mechanical strength has the beneficial effects that, according to the anti-twisting cable with the high mechanical strength, the outer protecting jacket and the inner protecting jacket can be prevented from generating relative rotation through using the reinforcements; thus, the anti-twisting ability is improved; the wear generated between the inner protecting jacket and the outer protecting jacket is avoided; through arranging the reinforcements, the mechanical strength of the anti-twisting cable with the high mechanical strength can be also increased; through arranging the armoring layer, the mechanism strength of the cable can also be increased; the anti-erosion ability is improved; the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the field of cables, in particular to a twist-resistant cable with high mechanical strength. Background technique [0002] With the rapid development of electronic communication technology, the requirements for spring telephone cables for various electronic communication systems are getting higher and higher. Not only must they have high elasticity, high wear resistance and softness, but they should also be miniaturized and lightweight. , Anti-interference characteristics. The currently used telephone cables have four cores insulated and extruded elastomeric sheaths; there are also two pairs of conductors twisted after insulation and then extruded elastomeric sheaths. The above two structures can meet the requirements of high elasticity and high wear resistance when the material is suitable, but they cannot resist the interference of external electromagnetic waves, and there is mutual interference between the two pairs. In or...

Problems solved by technology

The above two structures can meet the requirements of high elasticity and high wear resistance under the condition of suitable materials, but they cannot resist the interference of external electromagnetic waves, and there is mutual interference between the two pairs

In order to prevent interference, some cables have been adjusted in structure. After the insulating core is cabled, the shield is woven, and finally the elastomer sheath is extruded. This structure not only has a large overall size, but the interference between the core pairs still exists. Some cable pairs Each pair weaves split screens, and then weaves the total screen after the split screens. Although this structure can resist external electromagnetic wave interference and eliminate the mutual interference between each pair, it has a large structure size, heavy weight, poor elasticity and bendability. Unsuitable for laying in narrow spaces
