Abstract
It the utility model is related to one kind and surpass six class electricity comprehensive digital communication cables, the section of center framework is provided with arc shirt rim in cross and periphery termination, twists and cored wire is located in the groove position of center framework, arc shirt rim periphery is enclosed with restrictive coating.The utility model causes cored wire to be completely fixed in groove position using frame center's baffle and skeleton peripheral skirt, it ensure that the strand in center framework is fixed to cored wire position, twist to not misplaced between cored wire, cable core overall structure is more stable, cross talk resistance can substantially improve with return loss, and transmission frequency is more than 500MHz.Twist to cored wire and twist to resistance to crosstalk more excellent performance between cored wire.Center framework periphery arc shirt rim is in certain arc, and opening direction makes strand enter groove to cored wire more convenient with twisting that to enter groove direction to cored wire identical.
Description
Technical field
Digital communication technology is the utility model is related to, more particularly to one kind surpasses six class electricity comprehensive digital communication cables.
Background technology
Six class digital cable speed are high.In high-speed transfer, due to reasons such as electromagnetic coupling effects between line pair, hold
Signal cross-talk is also easy to produce, influences laser propagation effect.Therefore, six class digital cables typically use skeleton structure, by line to being fixed on bone
Rack slot position class, reduce the signal cross-talk between line pair.Six traditional class electricity comprehensive digital communication cables, using simple crossing skeleton structure,
Line by mould to being positioned in four quadrants of crossing skeleton.In actual production manufacturing process, line is to being that rotation mode enters
Groove, skeleton follows line, and to rotation, and in rotary course, skeleton muscle once deviates positioning or flanging, cored wire are easy to partially
From groove position, skeleton is caused to lose barrier and locating effect；Even if line is smooth to entering groove, because groove position is open type, line is to it
Between resistance to crosstalk effect do not reach still most preferably.
Utility model content
The utility model provides a kind of communications cable, and the groove position of skeleton is semi-enclosed, makes the skeleton grooves position of cable independent
Property it is stronger, cable core structure is more stable, and cross talk resistance can be more preferable between cored wire.
The utility model realizes above-mentioned purpose using following technical scheme.One kind surpasses six class electricity comprehensive digital communication cables, including in
Heart skeleton and the copper core conductor by being enclosed with polyolefin insulation layer form strand to cored wire, and the section of the center framework is in ten
Font and periphery termination is provided with arc shirt rim, twists and cored wire is located in the groove position of center framework, arc shirt rim periphery is enclosed with
Restrictive coating.
Further, the center framework arc shirt rim peripheral with it forms " ten thousand " word overall structure.
Further, the strand is consistent with the direction of rotation of the arc shirt rim of center framework periphery to the direction of lay of cored wire.
Further, the strand to cored wire or is shielded pair.
Further, the strand to cored wire or is surrounded with aluminum foil shielded band or braid shielded band.
The utility model causes cored wire to be completely fixed in groove position using frame center's baffle and skeleton periphery arc shirt rim,
It ensure that the strand in center framework is fixed to cored wire position, twist to not misplaced between cored wire, cable core overall structure is more stable, resists
Crosstalk performance and return loss substantially improve, and meet six class cable maximum transmission rate 250MHz standard requirement, adjacent strand
It is more excellent to cross talk resistance between cored wire.Center framework periphery arc shirt rim is in certain arc, and opening direction is with twisting to cored wire
It is identical to enter groove direction, strand is entered groove to cored wire more convenient.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram that the utility model surpasses six class electricity comprehensive digital communication cables.
In figure：1. copper core conductor, 2. polyolefin insulation layers, 3. center frameworks, 4. arc shirt rims, 5. restrictive coatings, 6. strands pair
Cored wire.
Embodiment
Utility model is described further below in conjunction with drawings and examples.Referring to Fig. 1, one kind surpasses six class digital communications
Cable, including center framework 3 and the copper core conductor 1 by being enclosed with polyolefin insulation layer 2 form strand to cored wire 6, in described
The section of heart skeleton 3 is provided with arc shirt rim 4 in cross and periphery termination, twists the groove position for being located at center framework 3 to cored wire 6
Interior, the periphery of arc shirt rim 4 is enclosed with restrictive coating 5.The arc shirt rim 4 peripheral with it of center framework 3 forms " ten thousand " word structure.Strand pair
The direction of lay of cored wire 6 is consistent with the direction of rotation of the arc shirt rim 4 of the periphery of center framework 3.Strand is to cored wire 6 or is shielding line
It is right.Strand is surrounded with aluminum foil shielded band or braid shielded band to cored wire 6.
Embodiment：Four pairs of copper core polyolefin insulations twist rotates into " ten thousand " word structure to cored wire 6 with certain twisting pitch
Skeleton, four pair twists is individually positioned in cored wire 6 center framework 3 and four groove positions of " ten thousand " word structure that arc shirt rim 4 is formed
It is interior, twist consistent with the direction of rotation of arc shirt rim 4 to the direction of lay of cable core 6, twist to can be with wrapped strata ester outside cable core 6
Band, it can also be shielded pair, it is necessary to during cable core bulk shielding to twist to cable core 6, can be with wrapped aluminum foil shielded band or using weaving
Shield band.Cable core skeleton uses " ten thousand " word structure, i.e. center framework 3 is common crossing skeleton, and four outsides of skeleton attach arc
Shirt rim 4, the direction of arc shirt rim 4 is identical, and arc shirt rim 4 not exclusively coats area of isolation, and center framework 3 uses polyolefine material
Overall time is extruded.Cored wire shields and cable core bulk shielding can optionally increase aluminum foil shielded band or braid shielded band.
