Abstract

The invention belongs to the field of cables, in particular to a double-tube cable. The cable comprises an outer protective layer and a plurality of electric units, and is characterized in that the outer protective layer is composed of two outer protective layer main bodies and a connecting part; the outer protective layer main body has a large head part and a small tail part; a clamping groove isformed in the head part of the outer protective layer main body; the tail part is provided with a clamping part; the head part and the tail part of the two outer protective layer main bodies are respectively connected with the tail part and the head part of the other outer protective layer main body in a clamping way through clamping grooves and the clamping parts, two staggered semicircular accommodating cavities are formed between the two outer protective layer main bodies and one connecting part, and at least one electric unit is arranged in each accommodating cavity. The invention also discloses a double-tube optical cable. The problems that a double-core cable or an optical cable is poor in tensile and compression resistance and inconvenient to maintain a broken circuit are solved; and the cable has the beneficial effects of being simple in structure, easy to maintain, good in compression resistance, good in tensile property, good in torsion resistance and the like.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a double-tube cable or an optical cable. Background technique [0002] In the prior art, CN204242668U discloses a double-core compact signal cable, which includes two copper core conductors with a semicircular cross-section, and the copper core conductors are sequentially coated with polytetrafluoroethylene film tape around the cladding, polyethylene The insulating layer constitutes the insulating wire core, and the two insulating wire cores are placed opposite to each other on both sides of the expandable graphite pad to form the cable core. Outer sheath. [0003] For another example, CN103093890A discloses a filler-free double-core semicircular conductor photovoltaic cable, which belongs to the technical field of wire and cable. The structure is composed of a conductor, an insulating layer, a sheath, and a tape layer. Insulation layer, tape layer inside the sheath, conductor and insulat...
