First Claim
Patent Images
1. A connector for a communications system, comprising:
- a plug housing having front and rear ends, an internal chamber opening on said rear end and defined by housing walls, and a plurality of slots extending through one of said housing walls adjacent said front end and into said internal chamber;
a plurality of contacts mounted in said slots for movement between retracted positions spaced from said internal chamber and inserted positions extending into said internal chamber;
a first insert disposed in said internal chamber having a front end proximal said front end of said plug housing, a first passageway extending from said front end of said first insert to said first insert rear end, a plurality of openings in a first insert wall adjacent said front end and aligned with said plurality of slots in said plug housing and extending into said first passageway;
a second insert disposed in said internal chamber having a front end proximal said first insert rear end, said second insert having first, second, third and fourth channels extending from a rear end to said front end of said second insert;
four pairs of wires extending from a cable sheath, each pair of wires passing through one of said first, second, third and fourth channels of said second insert and through said first passageway to said contacts in said internal chamber; and
an insert assembly having at least one insert member disposed adjacent at least one of said plurality of contacts, said insert assembly having a higher dielectric value than said plug housing.

Abstract
A connector for a communications system concentrates crosstalk in the front of a plug housing. The plug housing has front and rear ends. An internal chamber opens on the rear end and is defined by housing walls. A plurality of slots extend through one of the housing walls adjacent the front end and into the internal chamber. A plurality of contacts are mounted in the slots for movement between retracted positions spaced from the internal chamber and inserted positions extending into the internal chamber. An insert assembly has at least one insert member disposed adjacent at least one of the plurality of contacts. The insert assembly is made of a higher dielectric material than the plug housing.
