Abstract

The present invention provides a unitary, compact telecommunications interface adapter system. The adapter system comprises a bifurcated housing structure enclosing a modular connector and associated elements. The housing structure has a plug end constructed and arranged for connection to a 110-type telecommunications interface. The adapter further has an internal printed circuit board interface between the modular connector and a plurality of contact blades which are connected to and extend horizontally beyond the perimeter of the printed circuit board through channels so that they are exposed for contact outside the housing structure at the plug end. The telecommunications interface adapter system additionally comprises a support structure which has top and bottom spacially parallel extension members integrally formed with the housing structure at the plug end and disposed respectively above and below the contact blades.
