Abstract
The utility model relates to a tension cable, which comprises an insulation blanket sheath and a metal mask packed by the insulation blanket sheath. Two core wires and a ground wire stranded with each other are packed in the metal mask, wherein the two core wires comprise solid conductors and insulators packing the solid conductors, the ground wire at least comprises a plurality of conductors stranded with each other, and at least one strand of polyester wire, which is liable to curve and is high in tensile strength, is arranged between the stranded conductors. The utility model is characterized in that the tensile strength of the cable is improved as the high tensile strength and elastic-free polyester wire is adopted in the stranded ground wire; and the thickness of the insulator can be decreased on the premise of shielding effect, the space which the insulator takes up can be effectively reduced.
Description
[technical field]
The relevant a kind of transmission medium of the utility model, the cable of the strong tensile characteristics of especially a kind of tool.
[background technology]
Clamshell electronic device on the market as notebook computer, cover-lifting type mobile phone etc., adopts body and display to be articulated mostly, and both connect the mode of communication with cable.When the function of these electronic equipments from strength to strength, also increase as the number of cables of data transmission media, space layout is produced harmful effect; In addition; the outer skin protective layer of cable is except the function with the interference of shielding outer signals; in order to make cable in the bending process, be unlikely broken string; it should have certain elasticity and thickness; under the situation of cable constancy of volume; it takes up room also more and more, and this overall goal with present electronics miniaturization is conflicted mutually.
In addition; because position (as the corner of the housing) negotiation that cable and body are articulating; the volume of its contact-making surface is less; long-time folding wearing and tearing down; outer skin protective layer is aging; in case mechanism design runs into interference, be a kind of baptism to the tension and the anti-characteristic of waving of cable inner conductor, also can influence and use this cable to carry out the useful life of the clamshell electronic device of communication.
In view of this, the cable that is necessary to develop the strong tension of a kind of tool in fact and takies less space promotes the useful life of clamshell electronic device, and makes space layout more reasonable.
[summary of the invention]
Therefore, the purpose of this utility model promptly provides the strong tension of a kind of tool and takies the cable in less space, can promote the useful life of clamshell electronic device, and make space layout more reasonable.
For reaching above-mentioned purpose, the insulation sheath coated metal veil of cable of the present utility model, this metal veil coat two heart yearns and the mutual stranded entanglement of a ground wire, wherein, and the insulator that this two heart yearn comprises solid conductor and wraps up this solid conductor.This ground wire comprises mutually some strands of stranded leads at least, and stranded between these leads one Teduolong wire flexible, high stretch breaking strength is at least arranged.
Compared to prior art, the utility model utilization integrates the high stretch breaking strength of the Teduolong wire in ground wire, nonelastic characteristic, disperseed cable heart yearn stressed when receiving that external force is interfered, improve the tensile strength of this cable, but proper extension is used the useful life of the electronic equipment of this tension cable; Simultaneously, under the prerequisite that guarantees shield effectiveness, can suitably reduce the thickness of insulator, effectively reduce its footprint, make space layout more be tending towards reasonable.

Fig. 3 is the section structure schematic diagram of ground wire of twisted-pair feeder of an embodiment of tension cable of the present utility model.
[embodiment]
Describe as example with the cable 7-standard category 5 twisted pair 71 (consulting the finished product schematic diagram of the tension cable of Fig. 1) that generally uses at present, its by 4 pairs of twisted-pair feeders 71 by outward by 72 coat and constitute.As shown in Figure 2, sectional schematic diagram for a pair of twisted-pair feeder in the standard category 5 twisted pair, this twisted-pair feeder 71 is screen type twisted-pair feeder (Shieled Twisted Pair), isolated outside electromagnetic interference (the EMI of its insulation sheath 8 parcels, Electromagnetic Interference) metal veil 3, this metal veil 3 coats two heart yearns 1 and a ground wire 2 mutual stranded entanglement, wherein, the insulator 12 that this two heart yearn 1 comprises solid conductor 11 and wraps up this solid conductor 11, and load positive direction current signal and negative direction current signal on this two solid conductor 11 respectively, the electromagnetic field that utilizes this two electric current to produce interacts and offsets, and reduces the interference that comes from the outside.
Consult Fig. 3, enlarged diagram for above-mentioned ground wire 2, this ground wire 3 comprises the some strands of leads 4 that are coated in the insulating barrier 6, and these leads 4 adopt multiply (13/0.08) stranded in present embodiment, thereby breaks the stranded of the similar proper circle of the normally used 7 strands of conductors of present industry (7/0.127); Again, stranded between these leads 4 have one filiform 5 flexible, high stretch breaking strength at least, in present embodiment, this filiform 5 is the many dragons of 250D spy (tetoron) silks, and this Teduolong wire has the characteristic of flexible, high stretch breaking strength, nonelastic and high abrasion, and it is entangled with between each lead 4, guaranteeing present ground wire 2 specifications, and carry under the situation that its total overall diameter is constant after stranded, promoted the process capability of cable on tensile property greatly.
In the present embodiment, this heart yearn 1 adopts conventional UL1571 32AWG wire rod, but the thickness of insulator 12 is owing to the high stretch breaking strength of Teduolong wire, inelastic characteristic, under the prerequisite that guarantees shield effectiveness, can select the lower limit of UL1571 specification (0.05mm-2.54mm), then the external diameter of heart yearn 1 is 0.42 ± 0.03mm, effectively reduces its footprint.
Compared to prior art, the utility model utilization integrates the high stretch breaking strength of the Teduolong wire in ground wire, nonelastic characteristic, disperseed cable heart yearn stressed when receiving that external force is interfered, improve the tensile strength of this cable, but proper extension is used the useful life of the electronic equipment of this tension cable; Simultaneously, under the prerequisite that guarantees shield effectiveness, can suitably reduce the thickness of insulator, effectively reduce its footprint, make space layout more be tending towards reasonable.
