Abstract
The utility model discloses a flexible cable of a multilayer and multi-core structure, which is characterized by comprising a central support cord (3), a main conductor (1) and a sheath (5). The central support cord (3) is positioned at the most central position, the main conductor (1) is arranged around the central support cord (3), the sheath (5) is enclosed to the outermost layer, the central support cord (3) is two-layered, the inner layer of the central support cord (3) is formed by a central stranded core (6) and a plurality of inner layer auxiliary stranded wires (7) twisted around the central stranded core, the outer layer of the central support cord (3) is formed by a plurality of outer layer auxiliary wires (10) twisted around the inner layer, the outer layer auxiliary wires (10) and the inner layer auxiliary stranded wires (7) are different in twisted length and direction, and thereby the flexible cable has relatively high ductility and tensile strength.
Description
Technical field
The utility model relates to field of cables, particularly a kind of flexible cable.
Background technology
The cable that uses on mechanically moving, the cable as occasions such as elevator, mining are used needs high extension characteristics and tensile strength.
The utility model content
The purpose of this utility model is to provide a kind of cable of reeling that is used for electric energy transmitting or transfer of data, has higher ductility and tensile strength.
For achieving the above object, the utility model is by the following technical solutions:
A kind of flexible cable, adopt multilayer, multicore structure, by the center support rope, main heart yearn, three layers of formation of crust, most crucial place is the center support rope, the main heart yearn that the thin wire of many tape insulation skins constitutes is centered around on this center support rope, plastic peel is wrapped in outermost layer, the center support rope is a double-layer structure, the auxiliary twisted wire of internal layer on the stranded core in this center constitutes internal layer by stranded core in center and many twisteds, skin is made of the auxiliary twisted wire of the skin of a large amount of twisteds on internal layer, and the twisted direction and the twisted length of outer auxiliary twisted wire and the auxiliary twisted wire of internal layer are different.
Further technical scheme is, is provided with the littler twisted wire of diameter in the gap of the auxiliary twisted wire of described internal layer, and these twisted wires assist twisted wire all tangent with enveloping outer enclosure internally with internal layer.
Further technical scheme is, is mounted with ground lead between the described main heart yearn.
Further technical scheme is, described crust is made of two-layer rubber, is embedded with the antitorque braid that is made of the high-tensile fiber between two-layer rubber.
Adopt the flexible cable of this structure, even through using for a long time, the center support rope ruptures, and heart yearn can not damage yet, and has higher ductility and tensile strength.
Description of drawings
Fig. 1 is a schematic cross-section of the present utility model;
Fig. 2 is the cross section enlarged diagram of the utility model center support rope.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, this cable has three main heart yearns 1 that are made of the thin copper conductor 1a of the high flexibility that is coated with EPR insulated hull 1b, between main heart yearn 1, ground lead 2 is arranged, these lead-in wires are similarly the structure that EPR insulated hull 2b coats the thin copper conductor 2a of high flexibility, at the center of cable is exactly center support rope 3, center support rope 3 is coated with electro-insulating rubber skin 3b, cable sheath is made up of two-layer rubber 5a and 5b, be provided with antitorque braid 4 between two-layer rubber 5a and the 5b, this antitorque braid 4 is a high strength tensile plastic fiber, main heart yearn 1, ground lead 2 twisteds are on center support rope 3.
As shown in Figure 2, the stranded core 6 in the center of center support rope 3a is made of seven monofilament lines, the stranded core 6 in this center is centered on by the auxiliary twisted wire 7 of four internal layers, be provided with four thinner twisted wires 8 in the space between the auxiliary twisted wire 7 of internal layer, twisted wire 7 and 8 is coordinated coupling mutually, make it together tangent with enveloping outer enclosure 9 internally, the skin of center support rope 3a is made of the outer auxiliary twisted wire 10 of ten six roots of sensation, and the stranded core in these outer auxiliary twisted wires and center 6 is the same to be made of seven monofilament lines.The auxiliary twisted wire 7 of internal layer with the twisted length twisted of 36mm to the stranded core 6 in center, outer auxiliary twisted wire 10 with the twisted length twisted of 50mm to the auxiliary twisted wire 7 of internal layer.
