Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of composite cable integrating video, audio signal transmission.
Background technology
In circuit cable laying operation, owing to will meet the needs of the line arrangement such as transmission of video and voice transfer simultaneously, will simultaneously by coaxial cable together with the multi-cable parallel layings such as audio signal wire, so just bring inconvenience to cable laying operation, also add construction cost.Meanwhile, coaxial cable is subject to the tractive of external force unavoidably in construction laid processes, and the effect of this external force may cause the deterioration of cable transmission performance.Therefore, the reliability that cable uses can not ensure, cable will shorten useful life greatly.
Utility model content
The defect that the utility model overcomes prior art provides a kind of composite cable integrating video, audio signal transmission.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of composite cable integrating video, audio signal transmission; comprise cable core and external protection; described external protection is coated on outside described cable core; described cable core comprises a coaxial cable and an audio signal wire; be provided with a separator between described cable core and described external protection, between described cable core and described separator, be also provided with a packed layer.
Described coaxial cable comprises inner wire, insulating barrier, outer conductor and sheath composition.
Described audio signal wire comprises conductor, polyvinyl chloride insulation layer, screen and inner restrictive coating.
The naked soft copper skein silk of described conductor multiply is combined into.
Described separator is high abrasion nonwoven fabrics separator.
The utility model beneficial effect is: a kind of composite cable integrating video, audio signal transmission of the utility model, be made up of the multiple transmission line structure such as coaxial cable, audio signal wire, and by oversheath, they are wrapped in one, the needs of the line arrangement such as transmission of video and voice transfer can be met simultaneously, multi-purpose, make cable laying operation more convenient and quicker, also significantly reduce construction cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention will be further described:
Fig. 1 is the utility model composite cable structural representation.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth further below in conjunction with concrete diagram.
With reference to Fig. 1, a kind of composite cable integrating video, audio signal transmission, comprise a cable core and an external protection 5, external protection 5 is coated on outside cable core, and cable core comprises coaxial cable 1, audio signal wire 2.A packed layer 3, separator 4 is provided with between described cable core and described protection jacket layer.
Described packed layer 3 is made up of polypropylene mesh tearing film, for filling the space between coaxial cable 1, audio signal wire 2, to make whole composite cable outward appearance rounding.Described separator 4, by the nonwoven fabrics separator of high abrasion, for coaxial cable 1, audio signal wire 2 and packed layer 3 being wrapped in one, preventing cable core loose, making cable laying operation more convenient and quicker.Described protective sleeve 5 is by elastomeric polyvinyl chloride sheath.
Described coaxial cable 1 is made up of inner wire 11, insulating barrier 12, outer conductor 13 and sheath 14, inner wire 11 is single naked copper free wire, insulating barrier 12 is the little and stable low density polyethylene (LDPE) insulating barrier of dielectric constant, outer conductor 13 is the naked soft copper silk woven shield of high count, and sheath 14 is pvc sheath.The coaxial cable be made up of above material ensure that the reliable and stable of the transmission performance parameters such as its decay, impedance.
Described audio signal wire 2 is made up of the insulating barrier 22 of conductor 21 and outer cladding thereof, screen 23 and inner sheath 24, conductor 21 is multiply naked anaerobic soft copper silk, insulating barrier 22 material is polyvinyl chloride insulation layer, screen 23 is the naked soft copper silk woven shield of high count, and sheath 24 is pvc sheath.
Said structure can transmission video signal, various cables that the function of audio signal is different gather together, therefore cable can meet the needs of the line arrangement such as transmission of video and voice transfer simultaneously, multi-purpose, makes cable laying operation more convenient and quicker, also significantly reduces construction cost.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-mentioned example and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
