Photoelectric hybrid cable

Abstract

The invention discloses a photoelectric hybrid cable, which comprises a hybrid cable core part and a transparent flame-retardant self-adhesive coating adhesive layer, wherein the hybrid cable core part comprises a plurality of optical fibers, a transparent second sheath and a support framework, and the plurality of optical fibers are fixed in the support framework; the flame-retardant self-adhesive coating adhesive layer wraps the outer surface of the hybrid cable core part; each of the two ends, with the smallest thickness, of the flame-retardant self-adhesive coating adhesive layer is provided with an arch-shaped self-adhesive coating adhesive part formed in an outwards-protruding mode. The arch belly part of the self-adhesive coating adhesive part is provided with a grey white conductive wire harness, and the outer surface of the conductive wire harness is wrapped by a transparent first sheath. A strip-shaped gas capsule filled with nitrogen is arranged on the inner side of the conductive wire harness; one side of the strip-shaped gas capsule abuts against the conductive wire harness, and the other side of the strip-shaped gas capsule abuts against the hybrid cable core part. The tensile capacity of the invisible photoelectric hybrid cable is improved, and the gas capsule is arranged between the first sheath and the second sheath, so that the overall bending resistance is improved; and the cable can be ensured to be effectively fused into the environment background color.

Description

technical field [0001] The invention relates to the field of optical cable production, in particular to a photoelectric hybrid cable. Background technique [0002] The existing invisible optical cable is basically a single optical fiber coated with transparent self-adhesive coating glue, which has the disadvantages of poor tensile strength, bending resistance, and poor flame retardancy; moreover, it can only transmit optical signals and has a single function .
