Abstract

The utility model provides an elevator cable which belongs to the technical field of optical communication transmission and helps to the solve the problems of poor material flexibility and weak anti-external-electromagnetic-interference performance of a conventional data cable. The elevator cable comprises fiber bushings from the first fiber bushing to the eighth fiber bushing and a sheath assembly sleeved outside the fiber bushings from the first fiber bushing to the eighth fiber bushing. The fiber bushings from the first fiber bushing to the eighth fiber bushing respectively comprises a cable core formed by stranding a plurality of metal wires and a cable core bushing arranged around the cable core. Each fiber bushing of the fiber bushings from the first fiber bushing to the fourth fiber bushing is closely attached to the adjacent two fiber bushings and the fiber bushings from the first fiber bushing to the fourth fiber bushing are arranged to be rectangular in shape with the circle center of the sheath assembly being the center. The sheath assembly comprises an outer sheath, a signal shielding layer and an inner sheath, wherein the inner sheath, the signal shielding layer and the outer sheath are wrapped on the fiber bushings in sequence from the inside out; and the signal shielding layer is internally provided with a ground wire. The elevator cable has the advantages of being good in material flexibility, strong in external electromagnetic interference resistance and long in service life.

At present, patent publication No. is that CN202711846U discloses a kind of data cable, this data cable comprise a hollow insulating sleeve, be located at isolation skeleton and four groups of twisted pair wires of insulating sleeve inside, insulating sleeve interior separation is gone out four cavitys by isolation skeleton, four groups of twisted pair wires are arranged in corresponding cavity, adopt that isolation frame design causes that wire rod pliability is poor, a little less than the anti-outside electromagnetic interference of cable.

Summary of the invention

The purpose of this utility model is to have the problems referred to above for existing technology, has proposed that a kind of lightweight, pliability are high, long service life, a kind of elevator cable that anti-outside electromagnetic interference ability is strong.

The purpose of this utility model can realize by following technical proposal: a kind of elevator cable, comprise the first to the 8th ferrule and be sleeved on the first jacket assembly to the 8th ferrule outside, the first to the 8th described ferrule includes the cable core being twisted into by strands of metal wire and the cable core sleeve pipe arranging around cable core, in first to fourth ferrule, each ferrule and the tight welt of adjacent two ferrule and first to fourth ferrule are arranged in a rectangle centered by the jacket assembly center of circle, and the 5th to the 8th ferrule is respectively near each angle of rectangle;

Described jacket assembly comprises oversheath, signal shielding layer and inner sheath, and described inner sheath, signal shielding layer and oversheath is coated on ferrule successively from the inside to the outside, in described signal shielding layer, is also provided with ground wire.

In above-mentioned a kind of elevator cable, in first to fourth described ferrule, in any two ferrules, be provided with support bar, in the 5th to the 8th described ferrule, in any two ferrules, be provided with support bar.

In above-mentioned a kind of elevator cable, the angle that described ferrule and described rectangle diagonal are is α, and described α angular range is 0 degree to 30 degree.

Compared with prior art, the utility model arranges ferrule and is the arrangement of " X " type, and four support bars are separately positioned in four ferrules, have strengthened optical cable tensile anti-pressure ability; Adopt aluminium foil to add tinned copper wire as signal shielding layer material, the anti-outside electromagnetic interference of optical cable is strengthened; Cable core sleeve pipe adopts polyethylene foamed to make wire rod pliability better and extend wire rod useful life.
