Abstract

The invention relates to a cable, in particular to a load-bearing compression-resisting cable for moving occasions and a manufacturing method thereof. When insulation wire cores of the cable are cabled and twisted, aramid tensile pieces consisting of bundled aramid and rubber thickening layers are arranged in the gaps; a liner layer made of butyronitrile rubber is extruded outside the cabled and twisted insulation wire cores; the outer side of the liner layer is coated with a shielding layer formed by braiding tin-plated copper wires; a sheath layer made of chloroprene rubber is extruded outside the shielding layer; and a layer of armoured layer which is armoured by means of metal bands in an internal interlocking manner is covered outside the sheath layer. The cable can ensure that the self weight of the cable and the weight of corollary equipment in specified range can be loaded under the condition of bending at high frequency, and the damage of external tension to the cable is reduced. Meanwhile, the load-bearing compression-resisting cable can prevent the damage of other external radial pressure to the inner side of the cable, has the advantages of super softness, high tensile, easy assembly, high physical compression resistance and simple production method, and facilitates large-scale industrial production.

Description

technical field [0001] The invention relates to cables, in particular to a load-bearing and compression-resistant cable for mobile occasions used in an environment of super softness, high tensile strength, high resistance to physical compression, and high-frequency repeated bending, and a manufacturing method thereof. Background technique [0002] Existing cables for mobile applications mainly use copper wires with a diameter of 0.5mm or less (which can be plated with a metal layer) for bundle twisting, and then perform twisted-pair cabling, braided shielding, steel wire armor and sheath. In the jacket layer, it mainly plays the role of tensile strength. The characteristic of this kind of cable is that its flexibility is weakened by the influence of the shielding layer and armor layer; at the same time, the cable itself is heavy and inconvenient to use; it is easy to be damaged especially when it is impacted by physical external force, and it cannot meet the high-frequency r...
