Connector assembly for flexible circuits

The present invention generally relates to the field of circuit board connectors and more particularly relates to a flex connector for making high speed, high density, shielded, electrical interconnections. A flex connector assembly is provided having a plug assembly and a receptacle assembly for electrically connecting with the plug assembly. The plug assembly includes a plug housing, a first plug interface surface and a plug flex connector having a first portion with a plurality of conductive protrusions thereon, wherein the plug flex connector is fixed in the plug housing such that the conductive protrusions are positioned on the first plug interface surface. The receptacle assembly includes a receptacle housing, a first receptacle interface surface and a receptacle flex connector having a plurality of conductive protrusions thereon, wherein the receptacle flex connector is fixed in the receptacle housing such that the conductive protrusions are positioned on the first receptacle interface surface. The conductive protrusions of the plug assembly are aligned to contact conductive protrusions on the receptacle assembly when the plug assembly and receptacle assembly are connected. To provide EMI and RFI shielding, the housing of the plug and receptacle assemblies are preferably made of conductive metallic material.
