Abstract

A PC card of limited height (5 or 10 mm) is constructed with an extendable connector at its rear end for connection to a tall plug such as an RJ (telephone-type) plug that is designed to fit into a receptacle of large height. The connector apparatus is formed by a plastic molded rear end cap (22) at the rear of the PC card, with the cap having a slot (102) and with an adaptor platform (52) being slidable in the slot between an extended position wherein a rear portion of the platform projects a plurality of millimeters rearward of the end cap, and a stored position wherein the platform rear end is about flush with the cap rear surface. A hold-down (54) is pivotally mounted on the platform, the hold-down being pivoted down into a platform recess in the stored position and being pivoted up above the top of the PC card (10) to form a receptacle for receiving the plug in the deployed position. The slot in the cap has cap slot walls extending 360° around the slot axis (104), to provide a rugged support for the platform. The hold-down has a middle portion that lies uppermost when receiving a plug, with the middle portion lying forward of the hold-down pivot axis in the stored position of the platform, and with the middle portion forming a handle (100) to help pull out the platform.
