Abstract
The utility model relates to a symmetric paralleled network cable, which comprises conductors, insulation layers, auxiliary shields, winding layers, a main shield and a sheath, wherein the conductors are covered with the insulation layers; the two conductors with the insulation layers are straightly placed in parallel, and an earth wire is additionally arranged, so that the auxiliary shields are wound by hot-melting aluminium foil, and then are wound by hot-melting Nylar; core wires adopt the parallel structure during pair twisting process, and adopts the back-twist cabling method during cabling process; and the sheath adopts an uvioresistant sheath material. The utility model belongs to the filed of communication cables, is an ultra-high frequency symmetric paralleled network cable, and reduces total difference value of the twisting coefficients between line pairs, the distances of the conductors keep good consistent; and the impedance, the attenuation, the distance and the internal delay skew can be improved effectively.
Description
Technical field
The utility model relates to a kind of symmetrical parallel network cable, belongs to the energising field of cables.Can be widely used in the Network Transmission cable, when hyperfrequency, improve the transmission performance of Network Transmission.
Background technology
The initial progress of ethernet technology comes from many pioneer's technological projects of Xerox's palo alto research centre.It is conventionally believed that Ethernet invented in 1973, then the Robert. Metcalfe (Robert Metcalfe) has write the memorandum of one piece of relevant Ethernet potentiality for the boss of his PARC.But the Metcalfe it will be argued that Ethernet is just appearance in several years afterwards, and in 1976, the assistant David Boggs of Metcalfe and Ta delivered the article of a piece " Ethernet: the distributed packet technology of local area computer network " by name.Henceforth ethernet technology has just obtained fast development, and in the process that network constantly spreads, the user continues to develop into 100Mb/s from 3Mb/s, up-to-date 10G Ethernet under the surging situation to the requirement of bandwidth and network interconnection.
Cable is as the carrier of transmission signals, also in continuous renewal, to satisfy transmission requirements, phase delay is one of key parameter of decision high frequency symmetrical cable communication distance, some communication protocol has clearly regulation to the minimum length of Frame, if the phase delay of link excessive (relevant with equipment time-delay on the phase delay of cable and the link) easily causes losing of Frame when conflict takes place, line to the phase delay difference excessive, can cause the mistake of parallel transmission data time frame.
Simultaneously, institute's employing construction of cable grid line adopts stranded mode pair twist mostly in the market, cause the consistency of conductor spacing bad easily, thereby transmission performance is restricted when hyperfrequency.
Therefore, need a kind of line that can effectively reduce to a total stranded coefficient difference, to impedance, decay, to, internally delay inequality all obtains effective improved technology, solves the limited defective of transmission performance, improve transmission speed, solved losing and a wrong difficult problem of Frame.
The utility model content
The utility model has been done technological improvement at the losing of Frame in the transmission course in the ethernet technology, mistake and the limited defective of transmission speed to existing cable technique.
In order to realize this purpose, the utility model is finished by following measure: the utility model provides a kind of symmetrical parallel network cable, specifically comprise conductor, insulation, branch shielding, wrapped, total shielding, sheath composition, adopt parallel construction during the conductor core wire pair twist, divide shielding to adopt the hot melt aluminium foil wrapped, reusable heat fusibleness wheat is drawn wrapped, adopts the stranding mode of not back twist during stranding.
Further, described conductor is coated on the inside of insulating barrier, and two straight parallel are put and added a ground wire, form one group of pair twist split screen line;
Further, described branch shielding adopts the hot melt aluminium foil wrapped;
Further, it is wrapped that described lapping layer adopts the hot melt wheat to draw, and can effectively reduce the relative displacement between pair twist two heart yearns, to impedance, to, internally the improvement of delay inequality performance is obvious;
Further, vertical two-sided aluminium foil copper wire braiding is adopted in described total shielding;
Further, described stranding mode adopts not back twist cabler stranding.
The utility model has the following advantages with respect to existing technology:
1, reduced stranded coefficient difference: because the utility model adopts the hyperfrequency symmetrical parallel network cable of unique parallel construction, the spacing high conformity between two pair twist heart yearns;
2, transmission performance improves: because the high conformity of conductor spacing, transmission performance can be significantly improved when hyperfrequency;
3, prevent losing and mistake of Frame: because of the phase delay of link excessive or line to the phase delay difference excessive, easily cause losing or mistake of Frame, the utility model just in time to impedance, decay, to, internally delay inequality has all effectively been improved;
4, to impedance, to, internally the delay inequality performance all has clear improvement: split screen adopts the wrapped shielding of hot melt aluminium foil, draw wrapped with the hot melt wheat again then, effectively reduced the relative displacement between pair twist two heart yearns, to impedance, to, internally the delay inequality performance all has clear improvement;
5, prevent the twisted pair wire upset: adopted the stranding mode of not back twist, and pitch is arranged, can solve flexibility, the bending property problem of cable.
