Description
Technical field
This utility model is related to a kind of data cable, is specifically related to a kind of data cable of triangle oversheath.
Background technology
With social development, Development of Communication is increasingly swift and violent, and the continuous lifting with network speed, to network cable
Require also to improve gradual.On market, cable is modal is exactly circular cable, internal frame, thin one layer of oversheath.Circle
In the close and numerous rectangular trough laying of shape cable, each area shared by circular cable is a foursquare face
Long-pending.When being laid using circular cable, the volume of trough will have 21.5% wasted by circular cable.Simultaneously when perhaps
When how circular cable lays simultaneously, alien cross-talk between cable for the cable is unavoidable.Such alien cross-talk is to line
The transmission performance of cable is that have very serious impact.It is not subjected to AXT to reduce cable, can only reduce in trough
Circular cable lay quantity.
And typically 20 pounds of the pulling force of circle cable.In construction, slightly cable will be broken by overexertion, and result is exactly
Do over again, increasing construction cost and engineering time is huge economic loss.The crush resistance of circular cable is poor, and cable is easily subject to
Crimp, has influence on the lay of inner wire pair.Such situation has tremendous influence to cable itself and network stabilization.
For the high engineering project of corresponding technical requirements, the drawbacks of in order to overcome existing cable, have using shielded cable
Way, but this way is expensive, and difficulty of construction is big.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of data cable of triangle oversheath, this data
The above-mentioned problem such as the transmission performance of the existing cable of cable effectively solving is poor, stretching resistance is weak.
Technical problem to be solved in the utility model employs the following technical solutions to realize:
A kind of data cable of triangle oversheath, it includes insulating sheath, isolation skeleton and some groups of twisted pair wires；And it is each
Group twisted pair wire all carries out keeping apart being placed in insulating sheath by isolating skeleton；Described insulating sheath is triangular in shape, wherein, isolation
Skeleton includes some separation retaining sheet, and this isolation skeleton is in the shape of a spiral.
This utility model further improvement is that: the cross section of described isolation skeleton is in " x " type.
This utility model further improvement is that: described twisted pair wire be four groups, and each group twisted pair wire be respectively placed in " x " type every
Between the separation retaining sheet of skeleton.
This utility model further improvement is that: described separation retaining sheet is insulator.
This utility model further improvement is that: described isolation skeleton is formed in one.
The beneficial effects of the utility model are: this data cable, and insulating sheath adopts triangular structure, and in insulating sheath
Portion is provided with spiral separation retaining sheet；Thus realizing cable structure stably firmly, and when cable receives external force extruding, triangle
The internal twisted pair wire of the structural defence of shape is not subject to external influence.The setting of spiral separation retaining sheet, it is right not only to eliminate
Twisted wire, to outside electromagnetic interference, improves performance and the safety of network cable；And resistance to tension is strong.For same body
Long-pending trough, can lay more cables using this data cable；Then reduce the cost laying trough, also improve sky
Between utilization rate.
This data cable high bandwidth, high safety, utilization rate are high, and anti-extrusion, resistance to tension is strong, high stability.
Brief description
Fig. 1 is this utility model cross-sectional structure schematic diagram.
Wherein: 1- insulating sheath, 2- isolates skeleton, 3- twisted pair wire, 4- separation retaining sheet.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that this utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and this utility model is expanded on further.
As shown in figure 1, a kind of data cable of triangle oversheath, it includes insulating sheath 1, isolation skeleton 2 and some
Group twisted pair wire 3；And each group twisted pair wire 3 all carries out keeping apart and is placed in insulating sheath 1 by isolating skeleton 2；Described insulating sheath 1
Triangular in shape, wherein, isolation skeleton 2 includes some separation retaining sheet 4, and this isolation skeleton 2 is in the shape of a spiral；Thus increased cable
Resistance to tension.
The cross section of described isolation skeleton 2 is in " x " type；And twisted pair wire 3 is four groups, and each group twisted pair wire 3 is respectively placed in " x "
Type is isolated between the separation retaining sheet 4 of skeleton 2.Then that four groups of twisted pair wires 3 can be allowed to carry out is stranded for " x " type isolation skeleton 2, right to eliminate
The external electromagnetic radiation of twisted wire 3, reduces between every group of twisted pair wire 3 while improving safety, tensile property to a greater extent
Crosstalk.
Described separation retaining sheet 4 is insulator；The electromagnetic radiation external to eliminate twisted pair wire 3, reduces every group to a greater extent
Crosstalk between twisted pair wire 3.
Described isolation skeleton 2 is formed in one；It is further ensured that the stability of this cable structure.
Because triangle is the most stable firm result, thus the crush resistance of cable is very high.Due to internal insulation bone
The setting of frame 2, the structure of Internal cable and lay will not be changed because of external force.
Meanwhile, the area of triangle is foursquare 1/2nd, then can make full use of the space in trough, heap
Space in trough after folded will not have gap.The trough of same volume, triangle cable lays than circular cable more
21.5% number of cables.Thus reducing the cost laying trough, also improve space availability ratio.
Before twisted pair wire 3 strand, carry out rolling shape by the requirement to lay for the twisted pair wire 3 to solid wire, then twisted again
Right, so ensure finished product twisted pair wire 3 when being affected (as pulling force is excessive, bending, construction) by external force, in every group of twisted pair wire 3
Lay will not produce displacement, so that it is guaranteed that the lay in every group of twisted pair wire 3 remains equilibrium, network service is then completely secured
Quality.
Isolated using " x " type separation retaining sheet 4 between every group of twisted pair wire 3, and reach balance and unification using this technology.
And separation retaining sheet 4 is in the shape of a spiral, " x " type isolation skeleton 2 can allow four groups of twisted pair wires 3 carry out twice stranding then, to eliminate externally
Electromagnetic radiation, reduce crosstalk between every group of twisted pair wire 3 while improving safety, tensile property to a greater extent.
The data cable of this triangle insulating sheath 1, increased the pulling force of cable, can reach 30 pounds nearly 14 kilograms；
Reduce the probability that cable is done over again in construction.
A kind of this utility model data cable of triangle oversheath of offer, this data cable, high bandwidth, high safety,
Utilization rate is high, and anti-extrusion, resistance to tension is strong, high stability.
Of the present utility model ultimate principle, principal character and advantage have been shown and described above.The technical staff of the industry
It should be appreciated that this utility model is not restricted to the described embodiments, the simply explanation described in above-described embodiment and description is originally
The principle of utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has various change
And improvement, these changes and improvements both fall within the range of claimed this utility model.This utility model claims scope
By appending claims and its equivalent thereof.
