Abstract
The utility model discloses an anti-electromagnetic-interference flat data cable, comprising eight bunch-stranded cores each consisting of seven flexible round wires. The eight bunch-stranded cores are respectively wrapped by insulating layers to form eight bunch-stranded lines. The eight bunch-stranded cores are stranded in pairs to form four pairs of shielding stranded groups, outer surfaces of which are wrapped with one-sided aluminum foil tapes, respectively. The four pairs of shielding stranded groups are placed in parallel and are located in the same plane. A polyvinyl chloride layer wraps the outer surfaces of the four pairs of shielding stranded groups. Adjacent shielding stranded groups are isolated by the polyvinyl chloride layer. With super flexibility, the anti-electromagnetic-interference flat data cable of the utility model prevents wires from being broken or falling off at bent parts due to long-term fixation, and effectively prevents outside electromagnetic interference from entering in the cable and meanwhile internal signals from being radiated out.
Description
Technical field
The utility model relates to the high-speed data cable field, is specifically related to a kind of flat data cable of anti-electromagnetic interference.
Background technology
The structure of existing data cable is an extrusion foaming polyolefin insulation on silver-plated annealed copper wire conductor, and wrapped aluminium-plastic tape forms shielded pair outside two insulated heart yearns.Behind a plurality of shielded pairs set strandings, wrapped non-hygroscopic insulating tape, aluminium-plastic tape (aluminium lamination is outwardly) outside cable core, tin annealed copper wire braid shielded then, PVC material oversheath.
Summary of the invention
The utility model purpose provides a kind of flat data cable of anti-electromagnetic interference; This flat data cable has ultra flexible nature; Prevent to cause broken string to come off because of wire rod is fixed in the turning point for a long time; Can prevent effectively that external electromagnetic interference from getting into cable, also stops internal signal to radiate simultaneously.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of flat data cable of anti-electromagnetic interference; Said flat data cable comprises: eight bundle twisted wire cores of forming by 7 strands of soft round conductors, and these eight bundle twisted wire cores are coated with insulating barrier respectively and form eight bundle twisted wires; Four pairs of shieldings of the stranded in twos formation of these eight bundle twisted wires pair twist group; Said four pairs of shielding pair twist groups outer surface separately all is surrounded with the single face aluminium foil strip; And this four couple shields the parallel placement of pair twist group and is positioned at same plane; One polyvinyl chloride layer is coated on said four pairs of shielding pair twist group outer surfaces, and isolates through this polyvinyl chloride layer between the adjacent shields pair twist group.
Further improvement project is following in the technique scheme:
1. in the such scheme, said flat data cable length is 6.4 ~ 6.8mm, highly is 1.8 ~ 2.0mm.
2. in the such scheme, said single face aluminium foil strip by laminated polyester film and the thin aluminium lamination that is overlying on the polyester film laminar surface outward form, this aluminium lamination is positioned at the inboard.
3. in the such scheme, the diameter of said soft round conductor is 0.175mm.
Because the technique scheme utilization, the utility model compared with prior art has advantage and effect:
The flat data cable of the anti-electromagnetic interference of the utility model; Because the every pair of line is to all having adopted ultrathin single face aluminium foil, therefore every pair of line all has extremely strong metal screen layer protection, successful solution the particularity of traditional flat data cable owing to its structure; Make each line between the crosstalk problem of the signal problem that is difficult to overcome; And the introducing of extra-thin single face aluminium foil structure utilizes reflection, absorption and the skin effect principle of metal screen layer, realizes preventing electromagnetic interference and electromagnetic radiation; Prevent that effectively external electromagnetic interference from getting into cable; Simultaneously also stop internal signal to radiate, disturb the purpose of miscellaneous equipment work, therefore really realized flat data cable antijamming capability; And because this product structure is a platypelloid type, the outer quilt of wire rod of the gross thickness collocation 6.4mm width of 1.8mm will not take any unnecessary interior space, and migration accurately is arbitrary narrow corner in family; In addition, the ultra pliable and tough material of the outer quilt of wire rod can easily prevent to cause broken string to come off because of wire rod is fixed in the turning point for a long time, becomes good collocation invisible and tangible in the cyberspace and the interior space.At last, the frivolous good arrangement of this wire rod is easy to take in and be easy to carry.
Description of drawings

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: a kind of flat data cable of anti-electromagnetic interference, said flat data cable 7 comprises: eight bundle twisted wire cores of forming by 7 strands of soft round conductors 10 1, these eight bundle twisted wire cores 1 are coated with insulating barrier 2 respectively and form eight bundle twisted wires 3; Four pairs of shieldings of the stranded in twos formation of these eight bundle twisted wires 3 pair twist group 4; Said four pairs of shielding pair twist groups 4 outer surface separately all is surrounded with single face aluminium foil strip 5; And this four couple shields pair twist group 4 parallel placements and is positioned at same plane; One polyvinyl chloride layer 6 is coated on said four pairs of shielding pair twist group 4 outer surfaces, and isolates through this polyvinyl chloride layer 6 between the adjacent shields pair twist group 4.
Be specially: (the concrete specification requirement of conductor sees the following form the zinc-plated soft round conductor of bundle twisted wire core buying 7 dish ￠ 0.175mm; Be placed on the pay off rack of bundle strand equipment; According to " 1+6 " structure; It is stranded to adopt bundle strand pitch to be that 9.8mm carries out, and obtains bundle strand conductor, and average diameter of this bundle strand conductor is at ￠ 0.525mm.
Following table 1 is the specification requirement of the zinc-plated soft round conductor of ￠ 0.175mm:
