, the filling member 100 is used for the parallel lines in core group 200 to being isolated, and makes each parallel lines to right
Claim setting；The core group 200 is for realizing the data and signal for transmitting high frequency；The outer layer external member 300 is for playing protection
Effect, and then improve the service life of data cable.
Referring to Fig. 1, the filling member 100 includes solid support item 110 and multiple extension isolating bars 120, it is described solid
Several continuous support concave surfaces 111 are provided on support bar 110, each extension isolating bar 120 is set to two neighboring described
The junction of continuous support concave surface 111.It should be noted that the solid support item 110 is used to support entire data cable；Institute
It states and extends isolating bar 120 for the parallel lines in two core groups 200 to being isolated, to can be effectively avoided and be misplaced
Phenomenon.The continuous support concave surface 111 is used to carry the parallel lines pair in each core group 200.
Referring to Fig. 1, the core group 200 includes several parallel lines to 210, each continuous support concave surface 111 is used
In one parallel lines of corresponding support to 210, the extension isolating bar 120 is for being isolated two pairs of adjacent parallel lines pair
210；The outer layer external member 300 is coated on outside the core group 200.
In this way, passing through filling member, core group and outer layer external member, it is ensured that the symmetry of wire rod structure avoids line to hair
Raw inconsistent phenomenon；And due to being provided with solid support item and extending isolating bar, by two parallel lines to being isolated, Ke Yiyou
Effect reduces the electromagnetic interference between line pair, improves the structural stability of cable.
It should be noted that there are four continuous support concave surface 111, the parallel lines for setting on the solid support item 110
To there are four settings, four parallel lines are to being arranged in a one-to-one correspondence respectively on four continuous support concave surfaces.In this reality
It applies in example, the continuous support concave surface is arc-shaped concave.In this way, four can be formed by setting four continuous support concave surfaces
The inner cavity of parallel lines pair is accommodated, that is, four parallel lines being coated in outer layer external member are continuous at four to setting is respectively corresponded
Support concave surface, and again by extending isolating bar for adjacent parallel lines to being spaced one from so that each parallel lines to
There is independent space；On the one hand parallel lines pair can be fixed by extending isolating bar by setting, guarantee the structural symmetry of wire rod, separately
On the one hand 4 pairs of parallel lines pair can be effectively isolated, reduce electromagnetic interference mutual between 4 pairs of parallel lines pair, guarantee data line
Cable has higher speed rates；Importantly, can be to avoid subsequent by setting solid support item and extension isolating bar
The problem of each parallel lines are to occurring dislocation, weighing wounded during extruding cable.
It is appreciated that in the prior art, although some wire rods with central filler structure and by line to being placed on
In central filler structure, but since it is there is no that, to separating, still can generate dislocation for both threads, either
The central filler structure of setting still will appear the case where misplacing and interfering with each other without completely cutting off line pair completely；At some
In existing wire rod, also some are provided with central filler structure, but in existing many central filler structures, center is
Central filler structure with through-hole, this central filler structure for having through-hole are when coating outer layer external member, i.e., peripheral
Line is to can squeeze central filler structure, and since central filler structure has through-hole, thus its structural strength can not keep out it is outer
The line enclosed is to the extruding force to it, that is to say, that central filler structure can bear maximum pressure and also be less than what external belt was come
Extruding force, so that serious deformation can occur for existing central filler structure, structural intergrity is seriously damaged, and is caused not
The structure of each line pair can be supported, so that wire rod is not able to maintain symmetry, while its electric property carried is complete
It destroys, so can not reach the transmission requirement of high-frequency data completely；In addition, in some existing wire rods, since centre is filled out
The hardness for filling structure is harder so that coat each line to when, provide biggish upward top power due to abutting against part, from
And it is possible that top power is excessive, not there is buffering effect.
Therefore, adjacent parallel lines get up to isolation completely in order to enable extending isolating bar, guarantee is not in dislocation
The case where with weighing wounded, reduces electromagnetic interference mutual between adjacent parallel lines pair, is further ensured that the structural symmetry of cable, mentions
The high-frequency transmission ability of high cable；In order to guarantee the structural strength of central filler part, the anti-extrusion ability of cable is improved, is avoided out
The case where malformation of existing central filler part, guarantees the structural intergrity of filling member, allows to support each parallel lines pair,
So that data cable can keep the symmetry of height, guarantees the superiority of the electric property of data cable, reach high frequency
The transmission requirement of data guarantees that data cable has higher speed rates；In order to enable filling member has the same of buffer function
When, and can be improved whole structural strength.In one embodiment, referring to Fig. 1, the width for extending isolating bar is
Between it is narrow, and extend the structure that broadens, and the extension elongated end of the isolating bar far from the solid support item from centre to both ends
It is connected to the outer by shielded layer of the outer layer external member, the fixing end and institute for extending isolating bar close to the solid support item
Solid support item is stated to fix；The solid support item is solid construction, and the structural rigidity of the solid support item is greater than institute
The structural rigidity for extending isolating bar is stated, and the structural rigidity of the solid support item is less than central filler in the prior art again
The structural strength of layer.In this way, the extension isolating bar is connected to the outer layer external member far from the elongated end of the solid support item
It is outer on shielded layer, can be made extend isolating bar completely by adjacent parallel lines to isolation, guarantee is not in mistake
Position and the case where weighing wounded, electromagnetic interference mutual between adjacent parallel lines pair is reduced, is further ensured that the structural symmetry of cable,
Improve the high-frequency transmission ability of cable；By the way that solid solid support item is arranged, it is ensured that the structural strength of central filler part,
The anti-extrusion ability of cable is improved, the case where avoiding the occurrence of the malformation of central filler part, guarantees the structural integrity of filling member
Property, allow to support each parallel lines pair, so that data cable can keep the symmetry of height, guarantees data cable
Electric property superiority, reach the transmission requirement of high-frequency data, guarantee that data cable has higher speed rates；Simultaneously
Structural rigidity by the way that solid support item is arranged is greater than the structural rigidity for extending isolating bar, and the structure of the solid support item
Hardness is less than the structural strength of intermediate filling layer in the prior art again, while can making filling member that there is buffer function,
It can be improved whole structural strength again.In addition, be intermediate narrow by the width that setting extends isolating bar, and from centre to both ends
Extend the structure to broaden, on the one hand on the other hand can also guarantee structure by adjacent parallel lines to being isolated completely
Symmetry, improve the high-frequency transmission ability of cable, improve the structural stability of cable.
It should also be noted that, the elongated end for extending isolating bar far from the solid support item and the outer layer external member
It is outer gap is had by shielded layer, but the gap is not enough to that adjacent parallel lines is caused to show to occur misplacing when being squeezed
As.
It should be noted that the solid support item be polyethylene interstitital texture, polypropylene interstitital texture or polyethylene and
Polypropylene mixes interstitital texture.In this way, by setting PE, PP or the two mixture material, it is ensured that filling member it is soft
Soft and toughness, also, since intermediate filling member is more soft, it can be while fixed wire rod, so that it has centainly
Buffer function.In this way, the hatching solid part more soft by setting, can both guarantee the flexibility of cable entirety, effectively
Reduce the minimum bending radius of cable, so that cable is more soft, and can guarantee the supporting role of center-filled part again, improves
To the buffer function of each parallel lines pair.
Referring to Fig. 2, the parallel lines include two core wires 211 to 210 and are coated in the parallel lines pair
Metal screen layer 212 outside two core wires.The parallel lines further include insulation wrapping layer 213 to 210, and the insulation is wrapped
Layer is coated on outside the metal screen layer.The parallel lines further include at least one ground wire 214 to 210, and the ground wire is set to
In region between two core wires and the metal screen layer.It should be noted that the core wire 211 is used for transmission high frequency
Signal or data；The metal screen layer 212 is used to shield the interference signal outside core wire, improves the stability of core wire transmission；
The insulation wrapping layer 213 plays the role of improving parallel lines to structural stability for fixing entire parallel lines pair；Describedly
Line 214 acts on for realizing the ground connection of parallel lines pair.In the present embodiment, the metal screen layer is aluminium foil layer, copper foil layer, gold
Any one in layers of foil and silver foil layer.
It should also be noted that, guarantee the symmetry of parallel lines pair to further increase the structural stability of cable, into
And the transmittability of parallel lines pair is improved, the parallel lines further include the glue layer being coated in the insulation wrapping layer to 210,
The glue layer is attached between the insulation wrapping layer and the metal screen layer.In this way, by setting glue layer, Ke Yijin
One step improves the structural stability of cable, guarantees the symmetry of parallel lines pair, and then improve the transmittability of parallel lines pair.At this
In embodiment, the insulation wrapping layer can be PET band, be also possible to the type insulating wrapping strip of other materials.
Further, in order to improve the structural symmetries of parallel lines pair, the high-frequency transmission ability of parallel lines pair is improved, may be used also
To improve the high-frequency transmission stability of parallel lines pair, for example, in one embodiment, the metal screen layer is longitudinally coated on two
Outside core wire described in root, and the inner sidewall of the metal screen layer is fitted closely on the lateral wall of two core wires；In this way,
By setting metal screen layer longitudinal direction clad structure, the structural symmetry of parallel lines pair can be improved, improve the height of parallel lines pair
Movement Capabilities are kept pouring in, the stability of the high-frequency transmission of data cable can also be effectively improved.
Further, in order to improve the structural stabilities of parallel lines pair, the structural strength of parallel lines pair is improved, and then guarantee
The data transmission stability of parallel lines pair；For example, the insulation wrapping layer 213 is coated on the metal in a manner of spiral winding
Outside shielded layer；In this way, be coated on outside metal screen layer in the case where metal screen layer longitudinal wrap, then in wrapped form, thus
The structural stability of parallel lines pair can be improved, and strong around the structure that the set-up mode of cladding winding can also improve parallel lines pair
Degree, it can guarantee the symmetry of wire rod, and can guarantee the structural strength of wire rod, thereby may be ensured that the data of parallel lines pair
The stability of transmission.
Referring to Fig. 2, the core wire 211 includes insulating layer 211a and center conductor 211b, the insulation extrusion cladding
In outside the center conductor.It should be noted that the insulating layer 211a is used to play the role of insulation, and can also protect
Center conductor；The center conductor 211b is used for transmission high-frequency data.It should also be noted that, the insulating layer of two center conductors
It is by insulating cement together extrusion molding, also, the thickness of two insulating layers is identical.In this way, passing through setting together extrusion molding
Insulating layer can not only guarantee that the difference of two core wires minimized, but also can guarantee the symmetry of two center conductors, while also setting
Set is in that thickness is identical, and may further ensure that the high symmetry of two core wires, and then improves center conductor to high-frequency data
With the stability of the transmission of signal.
Further, in order to guarantee the symmetry of parallel lines pair, the transmission reliability of parallel lines pair is improved, and then improve flat
The high-frequency transmission ability of line pair；For example, in one embodiment, the central axis of the ground wire and two center conductors
Line be in isosceles triangle, the central axis of the ground wire is located at the apex of the apex angle of the isosceles triangle, two institutes
State center conductor central axis be located at the isosceles triangle two base angles apex.In this way, by by ground wire and two
Root center conductor is arranged on three vertex of isosceles triangle, thereby may be ensured that two center conductors are symmetric relation, and
And ground wire is also on the symmetry axis of two center conductors, i.e., symmetry axis passes through on the central axis of ground wire, while making ground wire
Also there is symmetrical relationship, therefore, the position of two center conductors and ground wire can both guarantee the height of the structure of parallel lines pair
Symmetry, and the transmission reliability of parallel lines pair can be improved, the high-frequency transmission ability of parallel lines pair can also be improved.Compared to
For existing twisted pair, i.e., for existing cable, the structure height of this programme is symmetrical, and may also reach up higher frequency
Data transmission.
It is appreciated that in the prior art, ground wire is set to the middle section of both threads pair by some wire rods, and by ground
Line is positioned close at filled layer position, i.e., ground wire is positioned close in entire wire rod by each line to after circle setting
The position of mandrel line is then positioned close to ground wire the position of intermediate filling layer for the application, and such bring is asked
Topic is, when carrying out coating entire wire rod, then two core wires can be made to squeeze the position of ground wire, so that ground wire cannot
It is symmetricly set between two core wires, thereby reduces the high-frequency transmission ability of wire rod；Also, ground wire meeting during extruding
Keep the patch and property of two core wires bad, that is, it is possible that there is gap, so that the symmetry of wire rod between two core wires
It is bad, further such that the performance of wire rod is unstable.Therefore, in embodiments, for example, the ground wire is set to described in two
Between core wire, and the ground wire is located remotely from the position of the filling member.In this way, through the position of setting ground wire far from
The vertex of the apex angle of isosceles triangle can then be guaranteed that ground wire is being maintained at two far from intermediate filling member by heart filling member
On the symmetry axis of root core wire, the case where squeezing ground wire will not occur in two core wires, ensure that the symmetry of two core wires, in turn
Improve the high-frequency transmission ability of cable；Simultaneously when coating outer layer external member, it is mutual that two core wires can also be avoided the occurrence of
The case where separation, guarantees that the lateral wall of two core wires is bonded to each other, and avoiding the occurrence of has gap between two core wires, guarantees cable
High symmetry, further improve the structural stability and reliability of cable.
