6) gap location between each described heart yearn is provided with yarn spare, and being arranged so that between each described heart yearn of described yarn spare is more firm.
Description of drawings
Fig. 1 is the utility model embodiment coaxial cable structure schematic diagram.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to Fig. 1, the utility model embodiment provides a kind of coaxial cable 1, comprises many heart yearns 11, and each described heart yearn 11 can be enclosed to form two-layer at least circular ring structure and stranded in a wrapper 12, between each of adjoining layer for stranded in the same way.Like this, each described heart yearn 11 of the utility model can be enclosed to form two-layer at least circular ring structure and stranded in a wrapper 12, between each of adjoining layer for stranded in the same way, compared with prior art, obviously reduced the impression between each heart yearn 11, obviously solve the distortion of internal layer coaxial inner conductor 11, obviously promoted the performance of product, do not influenced all the other product processing techniques simultaneously.
Further, in the utility model specific embodiment structure, each described heart yearn 11 can be enclosed to form three layers circular ring structure, and the twisting pitch multiple between each layer is 20-35 times.According to the characteristics of production process equipment, take three-decker lay configuration in the same way, for the stranding equipment of coaxial cable 1, multistage strand cage rotates in the same way.
Further, as shown in Figure 1, described heart yearn 11 comprises the inner wire 111 that coats successively from inside to outside, insulating barrier 112, and, outer conductor 113 and sheath 114.Particularly, the material of described inner wire 111 is solid bare copper wire, or copper covered steel wire, or tinned wird, or silver-coated copper wire, or silver-copper plated steel clad wire.
