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 insulation displacement 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; and
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 insulation displacement contacts in said internal chamber.

Abstract
A connector for a communications system provides desired levels of crosstalk by controlling the positions and lengths of the wires. The connector has an internal chamber opening on the rear end of the plug housing and defined by housing walls. A plurality of slots extend through one of the housing walls adjacent its front end and into the internal chamber. A plurality of insulation displacement contacts are mounted in the slots for movement between retracted positions and inserted positions extending into the internal chamber. A first insert is disposed in the internal chamber. The first insert has a front end proximal the front end of the plug housing. A first passageway extends from the front end of the first insert to the rear end of the first insert. A plurality of openings in a first insert wall adjacent the front end are aligned with the plurality of slots in the plug housing and extend into the first passageway. A second insert is partially disposed in the internal chamber and has a front end proximal the first insert rear end. The second insert has first, second, third and fourth channels extending from the rear end to the front end of the second insert. Four pairs of wires extend from a cable sheath. Each pair of wires pass through one of the first, second, third and fourth channels of the second insert and through the first passageway to the insulation displacement contacts in the internal chamber.
