Abstract
The utility model discloses a kind of composite cable integrating video, audio frequency and digital data transmission; relate to field of cable technology; comprise cable core and external protection; described external protection is coated on outside described cable core; described cable core comprises a coaxial cable, a data cable; 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.The utility model composite cable, owing to can transmission video signal, various cables that audio signal is different with the function of digital signal gather together, therefore can meet the needs of the line arrangements such as digital signal, transmission of video and voice transfer simultaneously, multi-purpose, make cable laying operation more convenient and quicker, also significantly reduce construction cost.
Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of composite cable integrating video, audio frequency and digital data transmission.
Background technology
In circuit cable laying operation, owing to will meet the needs of the line arrangements such as digital signal, transmission of video and voice transfer simultaneously, will simultaneously by together with the multi-cable parallel layings such as coaxial cable, data cable and power line, so just bring inconvenience to cable laying operation, also add construction cost.Meanwhile, coaxial cable and data cable are 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 frequency and digital data transmission.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of composite cable integrating video, audio frequency and digital data transmission; comprise cable core and external protection; described external protection is coated on outside described cable core; described cable core comprises a coaxial cable, a data cable; 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.
Described inner wire is single naked copper free wire, and insulating barrier is the little and stable low density polyethylene (LDPE) insulating barrier of dielectric constant, and outer conductor is the naked soft copper silk woven shield of high count, and sheath is pvc sheath.
Described data cable is made up of the insulating barrier of eight single anaerobic bare copper wires and outer cladding thereof and sheath.
Insulating barrier be dielectric constant little and stable high density polyethylene (HDPE) insulation, sheath is pvc sheath.
Described separator is high abrasion nonwoven fabrics separator.
The utility model beneficial effect is: because the utility model is made up of the multiple transmission line structure such as coaxial cable, data cable, and by oversheath, they are wrapped in one, the needs of the line arrangements such as digital signal, 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 frequency and digital data transmission; comprise a cable core and a protective sleeve 5; protective sleeve 5 is coated on outside cable core; cable core comprises coaxial cable 1, data cable 2, is provided with a packed layer 3, separator 4 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, data cable 2, to make whole composite cable outward appearance rounding.Described separator 4 is made up of the nonwoven cloth material of high abrasion, for coaxial cable 1, data cable 2 and packed layer 3 being wrapped in one, preventing cable core loose, making cable laying operation more convenient and quicker.
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 data cable 2 is made up of the insulating barrier 22 of eight core conductors 21 and outer cladding thereof and sheath 23, and conductor 21 is single naked copper free wire, and insulating barrier 22 is the little and stable high density polyethylene (HDPE) insulating barrier of dielectric constant, and sheath 23 is pvc sheath.The data cable be made up of above material ensure that the reliable and stable of the transmission performance parameters such as its decay, impedance, return loss and near-end crosstalk.
Because said structure can transmission video signal, various cables that audio signal is different with the function of digital signal gather together, therefore cable can meet the needs of the line arrangements such as digital signal, transmission of video and voice transfer simultaneously, multi-purpose, make cable laying operation more convenient and quicker, also significantly reduce 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.
