It after eliminating ground wire, and regard shielding band 210 as ground wire, optimizes the utilization rate of wire internal structure；Cancel ground wire simultaneously
Afterwards, core wire will not be scalded when processing to wire rod, so that signal transmission is more stable, signal can also reach the biography of higher frequency
It is defeated.The application uses shielding band longitudinally to coat and without ground configurations, and keeps stable physical structure and electric property,
To realize finished wire rod high-frequency transmission and processing practicability, meets a variety of process requirements, greatly improve generalization.
It should be noted that first glue layer is glue, that is, the glue being coated on shielding band.Specifically, institute
It states the first glue layer full coat to be overlying on the shielding band, passes through the full coating glue on shielding band, after high-temperature heating, glue
Water, that is, fusible for the shielding band compared to half traditional coating glue, can more firmly fix the structure of core wire,
Avoid the occurrence of loosely organized situation；It is directly contacted at the same time it can also to shield band, does not influence signal transmission, accelerated high
The transmission rate of frequency signal, and then the high frequency performance of high speed data cable is improved, stable parallel lines be both able to satisfy to realize
Finished product structure improves wire rod pliability, and is able to satisfy the transmission of the performances such as high frequency insertion loss.
It is appreciated that when the outer layer band 220 to high-frequency data cable carries out wrapped, it may appear that certain overlapping,
In the outer layer band 220 and unfolded outer layer band 220 of lap, it just will appear certain whole ask that be uneven
