Abstract

A connector system having a plurality of high-speed connector modules, an anti-decoupling connector shell, and a multi axis backshell is provided. The high-speed module provides a low signal degradation electrically conductive signal path for terminated wires of twisted pairs of wires. The high-speed module additionally provides for dense placement of the terminated wires within the connector shell. The connector shell provides an anti-decoupling mechanism to prevent decoupling of the connector shell from a socket type connector shell resulting from typical forces applied to the connector shell. The multi-axis backshell provides mechanisms to toollessly adjust the angle of the various components making up the backshell which in turn provides a specifically angled path for cables contained within the backshell.

Claims
