Abstract
The utility model relates to a coaxial cable for an automobile sounder, which comprises a conductor, a polyethylene insulation layer, a braiding and shielding layer and a polyvinyl chloride sheath, wherein the conductor is arranged in the polyethylene insulation layer; the braiding and shielding layer is arranged outside the polyethylene insulation layer, and the polyvinyl chloride sheath is arranged at outermost layer; the conductor is a straight single wire, and the polyethylene insulation layer is a physical foaming polyethylene insulation layer. The straight single wire conductor with 0.19MM diameter replaces a jagged single wire conductor of the prior art, the physical foaming polyethylene insulation layer replaces a tubular polyethylene insulation layer of the prior art, thereby, the utility model makes the cable structure and performance stable, and enhances the transmission performance.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of electric performance stablity, the automobile audio coaxial cable that transmission signals is good.
Background technology
As shown in Figure 2, existing a kind of automobile audio with the structure of coaxial cable is, be provided with a conductor 5, it is the zigzag monofilament of 0.19mm that this conductor 5 adopts diameter, this conductor 5 is to insert in the tubular polyethylene insulating barrier 6, being provided with woven shield 7 outside tubular polyethylene insulating barrier 6, is pvc sheath 8 outside the woven shield 7.Above-mentioned existing automobile audio with the shortcoming that coaxial cable exists is, the electrical property instability, and decay is high, causes transmission signals not good.
The utility model content
Technical problem underlying to be solved in the utility model is, overcomes the defective that existing automobile audio exists with coaxial cable, and a kind of improved automobile audio coaxial cable is provided, and it has electric performance stablity, the advantage that transmission signals is good.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of automobile audio coaxial cable comprises conductor, polyethylene layer, woven shield and pvc sheath, and this conductor is inserted in the polyethylene layer, is provided with woven shield outside polyethylene layer, and outermost layer is a pvc sheath; It is characterized in that described conductor is straight monofilament; Described polyethylene layer is the physically foamed pe insulation layer.
The utility model adopts the straight monofilament conductor of diameter 0.19mm, substitutes the zigzag monofilament conductor of prior art; Adopt the physically foamed pe insulation layer to substitute the tubular polyethylene insulating barrier of prior art, make the construction of cable and performance more stable, transmission performance improves greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a sectional structure chart of the present utility model
Fig. 2 is the sectional structure chart of existing automobile audio with coaxial cable
Embodiment
As shown in Figure 2, the utility model is to be made of conductor 1, physically foamed pe insulation layer 2, woven shield 3 and pvc sheath 4, conductor 1 is inserted polyethylene foamed insulating barrier 2, is provided with woven shield 3 outside this polyethylene foamed insulating barrier 2, and this woven shield 3 is pvc sheaths 4.The conductor 1 of present embodiment is to adopt the straight monofilament of diameter 0.19mm to make, and the external diameter of circular physical blowing polyethylene layer 2 is 3.1mm, and foam degrees is 69.1%.
The utility model adopts the straight monofilament conductor of diameter 0.19mm, substitutes the zigzag monofilament conductor of prior art; Adopt the physically foamed pe insulation layer to substitute the tubular polyethylene insulating barrier of prior art, make the construction of cable and performance more stable, transmission performance improves greatly.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
In sum, the utility model is on structural design, use practicality and cost benefit, it is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, have novelty, creativeness, practicality, the regulation that meets relevant novel patent requirement is so mention application in accordance with the law.
