Communication jack having a dielectric film between plug interface contacts

摘要

Embodiments of the present invention relate to designs for network jacks which can be used for cable connectivity. In an embodiment, the present invention is an RJ45 jack that utilizes a thin dielectric film between two layers of PICs that provide crosstalk compensation by way of their geometry. Compensation is achieved by way of capacitor plates which sandwich a thin dielectric film. This allows for the layers of PICs to be in close proximity and achieve higher coupling where desired, allowing a greater amount of compensation to occur close to the plug/jack contact point. This can have the effect of moving compensation closer to the plug/jack contact point, which in turn may reduce the amount of compensation needed further along the data path.

主权项

1. A communication jack for mating with a communication plug, said communication jack comprising:
a housing having an aperture for receiving said communication plug; a sled positioned at least partially inside said housing, a first end of said sled being proximate said aperture and having a mandrel, a second end being distal said aperture; a first plurality of plug interface contacts (PICs), each of said first plurality of PICs having a first section extending along a side of said sled and a second section formed around said mandrel; a second plurality of PICs, each of said second plurality of PICs having a first section extending along said side of said sled and a second section formed around said mandrel; and a dielectric film positioned between at least some of said first sections of said first plurality of PICs and at least some of said first sections of said second plurality of PICs, said dielectric film being further positioned between at least some of said second sections of said first plurality of PICs and at least some of said second sections of said second plurality of PICs.
