Abstract
The utility model discloses a flexible telephone communication cable comprising eight circular metal conductors. The external surfaces of the circular metal conductors are all covered by inner insulating layers. Each two adjacent eight circular metal conductors are intertwisted with each other to form a first twisted wire set, a second twisted wire set, a third twisted wire set and a fourth twisted wire set. The first twisted wire set, the second twisted wire set, the third twisted wire set and the fourth twisted wire set are sequentially arranged at intervals in a parallel mode. The external surfaces of the first twisted wire set, the second twisted wire set, the third twisted wire set and the fourth twisted wire set are all respectively covered by elliptical external insulation layers. The elliptical outer insulating layers of each two adjacent twisted wire sets are connected through connecting ribs. Several cavities are arranged in foaming layers. The volumes of the several cavities account for 40-60% of the volume of the whole foaming layers. Several polyester fiber wires are arranged in the elliptical insulating layers along the circumferential directions of the elliptical insulating layers. According to the flexible telephone communication cable of the utility model, wire broking and shedding due to that wire rods are fixed at a bent portion for a long time can be easily prevented; and intangible and tangible good match between network space and indoor space forms.
Description
Technical field
The utility model relates to telephonic communication cable field, is specifically related to a kind of flexible telephonic communication cable.
Background technology
Telephone wire is that single line is through twisting operation, then several groups of strands will be twisted into circular configuration with certain laying up pitch to line and carry out sheath again, this structure not only can be because workmen's pulling force is excessive, undue force causes the pitch that cable inner wire is right to change because stretching in the time of construction wiring, thereby have influence on digital cable to every electric transmission performance, and the cable of this circular configuration is also unfavorable for indoor wiring and finishing.
The structure of cable: the structure of common cable is that single line as the circular configuration of sheath, is mainly laid in residence interior trims netting twine or computer local area machine room to use PVC after stranding through strand.
Due to the limitation of the said structure of cable, in residence interior trims netting twine or computer local area machine room, the wiring of cable and finishing bring many inconvenience, suffer distortion, bending, the digital cable processed roughly when construction, cause quality unstable, unreliable; Lack certain ability that prevents from affecting because of force-extension ability serviceability, repeatedly wiring has increased production cost, has increased heavy burden and the mounting and installation cost of building structure, has promotion prospect widely.
Summary of the invention
The utility model object is to provide a kind of flexible telephonic communication cable, this flexible telephonic communication cable can easily reduce the dielectric constant of insulating barrier, thereby and then reach and reduce electric capacity and improved the transmission performance of cable, prevent that cable cross-talk simultaneously, also prevent from causing broken string to come off because wire rod is fixed on turning point for a long time, frivolous good arrangement, is easy to storage and is easy to carry.
For achieving the above object, the technical solution adopted in the utility model is: a kind of flexible telephonic communication cable, comprise: eight circular metal conductors, this circular metal conductor outer surface is all coated with foaming layer, described eight circular metal conductors are the stranded first twisted wire group that forms respectively between two, the second twisted wire group, the 3rd twisted wire group and the 4th twisted wire group, the first twisted wire group, the second twisted wire group, the 3rd twisted wire group and the 4th twisted wire group are arranged on parallel interval ground successively, the first twisted wire group, the second twisted wire group, the 3rd twisted wire group and the 4th twisted wire group separately outer surface are all coated with oval insulating barrier, adjacent twisted wire group connects by dowel between oval insulating barrier separately,
If there is individual cavity in described foaming layer, if the volume in this individual cavity accounts for 40 ~ 60% of whole foaming layer volume; In oval insulating barrier, circumferentially all have and be provided with some polyester fiber lines along it.
In technique scheme, further improvement project is as follows:
In such scheme, described oval insulating barrier length and height ratio are 10:3 ~ 6.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The flexible telephonic communication cable of the utility model, can easily reduce the dielectric constant of insulating barrier, thereby and then reach and reduce electric capacity and improved the transmission performance of cable, prevent that cable cross-talk simultaneously, also prevent from causing broken string to come off because wire rod is fixed on turning point for a long time, frivolous good arrangement, is easy to storage and is easy to carry.
