Abstract

Abstract The present invention provides a shielded circuit board module comprising a conductive frame and conductive cover for substantially shielding an entire circuit board. Apertures are provided in the frame so that connectors on the circuit board are exposed through these apertures rather than shielded by the conductive frame. The assembled conductive frame, cover and circuit board form a shielded circuit board connector module. According to the invention the shielded circuit board connector module can be mated with another circuit board in a parallel configuration. A receptacle frame is preferably mounted on the other circuit board to permit the module to be easily inserted therein so that the circuit boards can be connected. The receptacle frame provides for easy extraction of the module from its connection with another circuit board. In particular an eject handle and cam bars are coupled to the receptacle frame according to the invention to assist in extracting the module from its connection with another circuit board. A method of connecting the conductive frame and cover to the circuit board to assemble the shielded circuit board connector module is also provided.
