Abstract: The integrated shielding and mechanical support simultaneously addresses the problems of providing RF shielding for an electronic device such as a radio transceiver and providing a rigid mechanical assembly for the electronic device. Two conductive rails (120, 130) hold together multiple printed circuit boards (PCBs) (140, 160) having conductive layers (145, 165) to produce a four-sided shielding box (180) that protects certain electronic circuits on the PCBs from electromagnetic interference. An internal conductive shield (150) subdivides the inside of the shielding box to provide additional protection for sensitive circuitry. The shielding box inserts into an opening in a five-sided housing section (110) using guides (112, 114, 116, 118), which simplifies assembly of PCBs in the housing and facilitates automated assembly. A second housing section (190) attaches to the shielding box (180) once it is inserted into the five-sided housing section (110).

The connecting direction between the PC card and the circuit board is perpendicular to the insertion direction of the PC card.

Each cam plate has a continuously recessed guide path for guiding the PC card. The guide path has a guiding portion and a stop portion wherein the transition of the pivot pin from the guiding portion to the stop portion causes a defined rotation of the plug-in package about the pivot point wherein the plug-in package is rotatably arranged at the pivot point. This allows the PC card to make a pivot motion in order to accomplish the connection between the plug-in package and the circuit board.
