Abstract
The utility model discloses a communication cable for audio transmission. The communication cable comprises three wire cores, and each wire core comprises a conductor, a foaming plastic layer and an insulation layer from inside to outside. A hollow tube is arranged between the foaming plastic layer and the insulation layer, and the thickness of the hollow tube is not less than 0.8 mm. The hollow tube is spirally wound on the outer side of the foaming plastic layer, and the spiral winding spacing is not more than 3 mm. The three wire cores covered with insulation layers are arranged in a delta shape by an elastic tube being the center to form a cable core. The cable core is sequentially coated with a fastening layer, a braiding layer and an outer sheath layer. The communication cable is of new structure design, the compactness of the structure of the cable is improved through the fastening layer and the braiding layer, and air dielectric going into the cable can be increased through the hollow tube, so that the transmission quality is improved. Furthermore, the total weight of the cable is effectively reduced by the hollow tube, the foaming plastic layer and the elastic tube, so that the cable is convenient to install and lay.
Description
Technical field:
The utility model relates to communication cable, relates in particular to a kind of audio transmission communication cable.
Background technology:
Communication cable is mainly used in transmission of audio, 150kHZ and following analog signal and 2048kbit/s and following digital signal.Certainly under certain condition, also can be used for transmitting the above digital signal of 2048kbit/s.Be applicable in the built on stilts or pipeline laying circuit in city, the suburbs and some areas, but also direct-burried.
For traditional audio transmission cable, have the following disadvantages: be at first that structural compactness is poor; Secondly, be the stability deficiency of the signal transmission of cable; Be finally in the cable installation process because weight is larger, wasted a large amount of manpower and materials.
The utility model content:
In order to make up the prior art problem, the purpose of this utility model is to provide a kind of audio transmission communication cable, and structural compactness is good, and the audio transmission signal stabilization is strong, is convenient to mounting and installation.
The technical solution of the utility model is as follows:
The audio transmission communication cable, comprise three cores, it is characterized in that: described three cores are coated with foamed plastic layer, insulating barrier formation outward successively by conductor, between foamed plastic layer and insulating barrier, be provided with hollow pipe, the thickness of hollow pipe is not less than 0.8mm, the hollow pipe spiral winding is in the foamed plastic layer outside, the spacing of spiral winding is not more than 3mm, three cores of coated insulation layer are placed and are formed cable core in a triangle centered by elastic tube, cable core is coated with outward successively tightens layer, braid, external sheath layer.
Described audio transmission communication cable is characterized in that: the described layer of tightening adopts thickness to be not less than the overlapping wrapped formation of PTFE film band of 0.2mm, and wrapped Duplication is not less than 18%.
Described audio transmission communication cable is characterized in that: described braid adopts the overlapping wrapped formation of silver-plated copper strips, and the thickness of silver-plated copper strips is not less than 0.55mm.
The utility model has the advantages that:
The utility model structural design novelty, by tightening layer, braid etc., improve the structural compactness of cable, the while hollow pipe can increase and decrease air dielectric and enter, and improves transmission quality, hollow pipe, foamed plastic layer and elastic tube can effectively reduce the total weight of cable, are convenient to mounting and installation.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
The audio transmission communication cable, comprise three cores, three cores are by outer foamed plastic layer 2, the insulating barrier 3 of being coated with successively of conductor 1, between foamed plastic layer 2 and insulating barrier 3, be provided with hollow pipe 4, the thickness of hollow pipe 4 is not less than 0.8mm, hollow pipe 4 spiral windings are in foamed plastic layer 2 outside, the spacing of spiral winding is not more than 3mm, three cores of coated insulation layer 3 are placed in a triangle and are formed cable core centered by elastic tube 5, cable core is coated with outward successively tightens layer 6, braid 7, external sheath layer 8.
Tighten layer 6 and adopt thickness to be not less than the overlapping wrapped formation of PTFE film band of 0.2mm, wrapped Duplication is not less than 18%.
