Abstract

A communications card capable of being mounted in electrical communications with a computer has formed therethrough an aperture so sized and shaped as to be capable of receiving a physical/electrical media connector. The media connector has a biased retention clip, a contact pin block, and contact pins. The retention clip has several standardized characteristics including a broad fixed end protruding from an outer surface of the contact pin block. The broad fixed end tapers abruptly at a transition notch down to a narrow free end, capable of being manipulated by a user to remove the physical/electrical media connector from the aperture in the communications card. In use, a media connector is inserted directly into the aperture in the communications card, the aperture being in contact with a plurality of contact wires fixed within the communications card. The communications card is divided into a retractable access portion of the communications card which can be directly accessed by manipulating an actuating mechanism releasing a retention means thereby allowing a spring to push the retractable access portion of the card outside of the computer housing. The retractable access portion of the communications card may be reinserted back into the computer housing to be carried internally when not in use.
