Abstract
The utility model discloses a dual-branch line, which comprises two parallel cables which are connected with each other and of which the sections are '8'-shaped. The dual-branch line is characterized in that: four core wire pairs are arranged in each cable; each core wire pair comprises two core wires which are stranded with each other; each core wire comprises a middle conductor and an insulation layer wrapped on the outer side of the conductor; an aluminum foil layer is wrapped on the outer side of each core wire pair; a ground wire is positioned among the four core wire pairs; a woven layer is wrapped at the peripheries of the core wire pairs and the ground wire; a sheath is wrapped on the outer side of the woven layer; and the two cables are connected with each other through a connection part integrated with the sheath. According to the dual-branch line, internal crosstalk during signal transmission can be prevented, and external interference can be avoided; furthermore, the sheath of the dual-branch line is easy to stripe and difficult to damage; and the high-frequency signal transmission performance during data transmission can be well guaranteed.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to the shadow data telecommunication cable that a kind of 10G Ethernet is used.
Background technology
Along with the high speed development of information technology need; The speed that needs network faster, that capacity is bigger carries; And the existing Class 6 cable that is widely used in market can't satisfy on four pairs of cables the 100m Distance Transmission that every pair transmission rate all reaches 2.5Gb/s; Bandwidth also has only 250MHz, uses the bandwidth minimum requirements of 10G technology to be 500MHz, and under such high frequency; Noise jamming problem during wiring between the line group is difficult to solve through the simple numerical signal processing technology, therefore needs a kind of cable of design to solve the inside and outside and crosstalks and guarantee the performance under the high frequency.
Summary of the invention
The utility model technical problem to be solved provide a kind of anti-principal vertical line group and external interference can transmitting high-frequency signal seven types of two branch lines.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of pair of branch line; Comprise that two cross sections that are parallel to each other and link together are the cable of the figure of eight, is characterized in that: it is right all to have four pairs of heart yearns in the every cable, and every pair of heart yearn is to comprising two heart yearns stranded forming each other; Conductor in the middle of every heart yearn comprises and the insulating barrier that is wrapped in the conductor outside; Every pair of right outside of heart yearn is surrounded by aluminium foil layer, and ground wire is positioned at four pairs of centres that heart yearn is right, and said heart yearn is surrounded by braid to the periphery with ground wire; The outside of braid is surrounded by sheath, between said two cables through linking to each other with the integrated connecting portion of sheath.
Preferably, the width of said connecting portion is 0.1mm.
Compared with prior art; The advantage of the utility model is so two branch lines; Not only can prevent the internal crosstalk in the stop signal transmission; Also can prevent outside interference, and the sheath of this pair branch line is prone to peel off and not fragile, guaranteed transfer of data medium-high frequency signal transmission performances better.
Description of drawings
Fig. 1 is the schematic cross-section of the two branch lines of the utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Two branch lines of the utility model; As shown in Figure 1; Comprise that two cross sections that are parallel to each other and link together are the cable of the figure of eight; Every cable all has four pairs of heart yearns to 4 in each self-enclosed and every cable, and every pair of heart yearn comprises two heart yearns stranded forming each other, conductor 1 in the middle of every heart yearn comprises and the insulating barrier 2 that is wrapped in conductor 1 outside to 4.Said every pair of heart yearn is surrounded by aluminium foil layer 3 to 4 the outside, and ground wire 5 is positioned at four pairs of heart yearns to 4 centre.Heart yearn is surrounded by braid 6 to 4 with the periphery of ground wire 5, and braid 6 outsides are surrounded by sheath 7.The sheath 7 of two cables interconnects, and middle connecting portion 8 is one-body molded with sheath 7.
Preferably; In this pair branch line, conductor 1 adopts 99.99% oxygenless copper material, and insulating barrier 2 adopts the HDPE-3364 of U.S.'s import; Aluminium foil adopts the specification of 13mm*0.07mm; Braid is that copper wire or the aluminum-magnesium alloy wire braiding of 16mm*6mm*0.12mm processed, and sheath adopts LSZH (low smoke zero halogen, low smoke and zero halogen combustion cable material).
And the external diameter of two branch lines is 7.2mm, the distance between two cables, and promptly the width d of connecting portion 8 is 0.1mm.The thickness of sheath 7 is 0.5mm, and promptly the diameter that surrounds of braid 6 is 6.2mm.
Two branch lines so not only can be prevented the internal crosstalk in the stop signal transmission, also can prevent outside interference, and the sheath of this pair branch line is prone to peel off and not fragile, have guaranteed transfer of data medium-high frequency signal transmission performances better.
Claims (2)
1. two branch line; Comprise that two cross sections that are parallel to each other and link together are the cable of the figure of eight, is characterized in that: all have four pairs of heart yearns in the every cable to (4), every pair of heart yearn comprises two heart yearns stranded forming each other to (4); Conductor (1) in the middle of every heart yearn comprises and the insulating barrier (2) that is wrapped in outside the conductor (1); The every pair of heart yearn is surrounded by aluminium foil layer (3) to the outside of (4), and ground wire (5) is positioned at the centre of four pairs of heart yearns to (4), and said heart yearn is surrounded by braid (6) to the periphery of (4) and ground wire (5); The outside of braid (6) is surrounded by sheath (7), between said two cables through linking to each other with the integrated connecting portion of sheath (7) (8).
