Description
Technical field
The present invention relates to the data cable of electronic information technical field, relate in particular to the high speed transmission data cable of data-signals such as being used for audio frequency, video, image.
Background technology
Along with the continuous development of information network, information communication is more and more frequent, and the information exchange capacity is also increasing.Data cable is the important transmission medium of the network information, is faced with new technological change and innovation, will improve transmission rate on the one hand, satisfies the transmission and the exchange of big capacity information, will improve transmission stability on the other hand, guarantees the quality of message transmission.
Ethernet came out over more than 30 year; Network transmission speed has improved nearly thousand times; FDX Ethernet (10Mbps), 100 m ethernet (100Mbps), 802.3u Fast Ethernet (1000Mbps) have been experienced; Ten thousand mbit ethernets (10Gbps) till now, also will develop to 100,000 mbit ethernets (100Gbps) future.See that from present information transmission technology development ten thousand mbit ethernets will be the direction and the trend of the networking coming years, the demand that in the coming five years, is fit to the high-speed data transmission cable of ten thousand mbit ethernets will increase fast.
The development of the research and development of data cable and manufacturing and Ethernet synchronously, manufacturer releases 3 types (10Mbps), 5 types (100Mbps) earlier and surpasses 5 types and 6 types (1000Mbps), for information network construction and upgrading play an important role.Have now and surpass 6 types of data cables generally with solid skeleton and smooth type jacket structure; Such structural design; Cause easily in use inside and outside interference signal go here and there each other around and the not enough problem of decay surplus, thereby each item performance when influencing ten thousand mbit ethernet networks and using.
Summary of the invention
For solve inside and outside interference signal go here and there each other around and the not enough problem of decay surplus; The purpose of this invention is to provide a kind of super-six type unshielded data cable; This data cable improves the anti-cross-talk performance of cable, improved line to the cross-talk performance, improved the decay surplus.
In order to realize above-mentioned purpose, the technical scheme below the present invention has adopted:
A kind of super-six type unshielded data cable; This data cable isolates skeleton by insulation outer jointing jacket, cross and four groups of non-shielded pairs constitute; The inner ring of insulation outer jointing jacket is provided with and is the sawtooth pattern groove, and cross is isolated skeleton and adopted the expansion type cross to isolate skeleton, and cross is isolated will the insulate inner chamber of outer jointing jacket of skeleton and is isolated into four cavitys; Four groups of non-shielded pairs are separately positioned in four cavitys; And in a cavity, tear line is set, described non-shielded pair is made up of two leads, and lead is made up of copper conductor and the insulating barrier that is wrapped on the copper conductor.
As preferably, described insulating barrier adopts the HDPE insulating material.
As preferably, the foam degrees that skeleton isolated in described cross is 15%～35%.Preferred again, the foam degrees that skeleton isolated in described cross is 15%～25%.As further improvement, the length that skeleton isolated in described cross is 4.0～6.0mm, and cross is isolated the wideest of skeleton and is of a size of 0.4～0.8mm.
As preferably, the facewidth A of described groove is 1.0～2.0mm, and tooth depth is that H is 0.4～0.8mm, and groove is 0.3～0.6mm apart from the thinnest distance h of insulation outer jointing jacket outer wall.
As preferably, the pitch proportioning value of described four groups of non-shielded pairs is 13.0～13.5,9.0～9.4,16.0～16.5,10.0～10.5, and four groups of non-shielded pair pitch proportioning numerical value, the vertical mean pitch value of control twisted wire maximum deviation are below 1.5%.Above-mentioned structure reduced the error of pitch numerical value and actual pitch value, widened line to difference, improved the cross-talk index of product.
The present invention has following characteristics owing to adopted above-mentioned technical scheme;
1, the design oversheath adopts the purpose of degree of depth sawtooth pattern groove structure, is in order to make the right position of 4 groups of lines more fixing relatively, the distortion that is not easy to be moved, thereby make line between the distance maintenance more uniform and stable.Simultaneously, also can increase the cable volume inside, improve the anti-cross-talk performance of cable, solve cable problem of high-frequency signal phase mutual interference between cable in practical application.
2, skeleton employing foaming structure isolated in cross; Can reduce cross and isolate the dielectric constant of skeleton; Thereby improve the insulation characterisitic that skeleton isolated in cross; Guarantee cable under solid insulation and non-shielding construction, improved line to the cross-talk performance, keep the anti-combustion characteristic of safety of products and enough decay surpluses.
3, the pitch system of twisted pair wire process equipment transforms; Again the pitch proportioning value that design lines is right simultaneously; Reduced the error of pitch numerical value and actual pitch value, widened line to difference, further effectively improve the cross-talk performance between cable inside and cable and the cable.
The key technical indexes of product of the present invention is following:
(1) decay (ATT) :≤45.3dB/100m (500MHz)
(2) near-end crosstalk (NEXT): >=33.8dB/100m (500MHz)
