Abstract

A physical/electrical media jack is configured for electrically coupling with a physical/electrical media plug. The jack includes a housing having an interior chamber communicating with the exterior through an opening. Positioned on opposing sides of the opening are a pair of blocking ridges each having an inside sloping edge. In one embodiment, dovetailed splines are positioned on the exterior surface of the housing for receipt in complementary keyways formed in the border frame of a PC Card or the casing of an electrical apparatus. The jack further includes a retractable access portion having an aperture formed therein for receiving a media plug. The second end of the retractable access portion is slidably received within the opening in the housing. Outwardly projecting from opposing sides of the retractable access portion at the second end are a pair of retention lips. The retention lips bias against the blocking ridges to prevent unwanted removal of the retractable access portion from the housing. The retention lips and blocking ridges, however, are configured to enable removal of the retractable access portion through the opening without mechanical failure of the jack when sufficient outward force is applied to the retractable access portion.

(b) a contact wire attached to the retractable access portion, the contact wire having an end positioned to bias against the transition wire when the retractable access portion is in the first position.

13. A physical/electrical media jack as recited in claim 11, wherein the coupling means comprises:

(a) an aperture formed in the retractable access portion, the aperture being configured to receive the media plug; and

(b) a contact wire mounted to the retractable access portion and projecting into the aperture.

14. A physical/electrical media jack as recited in claim 13, further comprising means for preventing passage of the media plug completely through the aperture.
