Abstract

The utility model relates to a composite cable which comprises coaxial cables and a jacket, wherein two or more coaxial cables are arranged; a novel optical cable is arranged in the gap between adjacent coaxial cables; all the coaxial cables and the novel optical cables are coated by the jacket; each coaxial cable comprises a wire core conductor and a wire core insulator; the wire core conductor is coated by the wire core insulator; the novel optical cable comprises a fiber core, an internal coating and an outer jacket; the fiber core is coated by the internal coating; and the internal coating is coated by the outer jacket. According to the composite cable provided by the utility model, the novel optical cables and the coaxial cables are compounded and located in the gaps between the adjacent coaxial cables, so that the interior core of each cable is not needed to be reinforced. The composite cable is small in outside diameter, simple in production process and low in cost.

Description

A kind of composite cable

Technical field

The utility model relates to a kind of cable, and especially a kind of production cost is low, production process is controlled easily, the not easily broken core of optical cable, and satisfies the composite cable that under frequent mobile status, uses, and belongs to the cable technology field.

Background technology

At present, the electrical control insulated wire cores of flat type elevator trailing cable, insulation video monitoring cable adopts the various videos of transmission, data-signals such as coaxial cable, Shielded Twisted Pair.

And the structure of coaxial cable is solid insulation, shown in accompanying drawing 1, comprises cable cover(ing) 1, coaxial cable 2; Said coaxial cable has 2 or many, is wrapped up by cable cover(ing); Said coaxial cable 2 comprises core conductor 3, core insulator 4; Said core insulator 4 parcel core conductors 3; The coaxial cable of this structure causes technical indicators such as the decay, impedance of solid coaxial cable to be difficult to meet the requirements because of its reasons in structure, particularly poor anti jamming capability.

The utility model content

The utility model purpose is to have proposed for the deficiency that overcomes prior art that a kind of production cost is low, production process is controlled easily, the not easily broken core of optical cable, and satisfies the composite cable that under frequent mobile status, uses.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of composite cable comprises coaxial cable, sheath; Said coaxial cable has 2 or many; Be provided with novel optical cable in the space between the said adjacent coaxial cable; Said sheath wraps all coaxial cables, novel optical cable; Said coaxial cable comprises core conductor, core insulator; Said core insulator parcel core conductor; Said novel optical cable comprises fibre core, interior tegillum, oversheath; Tegillum parcel fibre core in said; Tegillum in the said oversheath parcel.

Preferably, said coaxial cable has 3, roughly is the isosceles triangle setting; Be provided with novel optical cable in the space between the said adjacent coaxial cable.

Because the utilization of technique scheme, the utility model compared with prior art has advantage:

The described composite cable of the utility model, with novel optical cable and coaxial cable is compound and space between adjacent coaxial cable in, need not inner separately core is strengthened, the external diameter of the composite cable of the utility model is little, production process is simple, cost is low.
