Abstract

A modular jack, for coupling with a physical/electrical media plug, comprises a frame, a rocker arm, electrical contacts, and a retractable cover guard for protecting the electrical contacts during nonuse. The retractable cover guard moves from a protective position to a retracted position when a physical/electrical media plug is inserted into the modular jack and returns to the protective position when the physical/electrical media plug is removed. While only a shallow insertion depth of the physical/electrical media plug is permitted, the rocker arm aligns and mechanically secures the physical/electrical media plug within the modular jack.

a base that is sized and configured to engage the RJ-series connector plug when the RJ-series connector plug is inserted into the opening, the engagement of the RJ-series connector plug with the base causing the rocker arm to pivot relative to the retractable connector;

first and second alignment arms extending from the base, the first and second alignment arms including alignment surfaces that are sized and configured to slidably engage the retention clip of the RJ-series connector plug; and

a retractable cover guard that is sized and configured to cover at least a portion of the opening in the frame, the retractable cover guard movable between a first position in which at least a portion of the opening is covered and a second position in which at least a portion of the opening is exposed to allow the RJ-series connector plug to be inserted into the opening.

19. The communications device as in claim 18, wherein the engagement of the media plug with the retractable cover guard when the media plug is being inserted into the opening causes the retractable cover guard to move from the first position to the second position.

20. The communications device as in claim 18, further comprising a storage position for the rocker arm when the RJ-series connector plug is not inserted into the opening and a use position in which at least a portion of the RJ-series connector plug is inserted into the opening.

21. The communications device as in claim 18, further comprising one or more locking ears extending from the first and second alignment arms of the rocker arm, the locking ears being sized and configured to secure the RJ-series connector plug in a fixed location.
