ABSTRACT:
An improved modular telephone-style jack featuring an improved contact configuration. The modular jack directly couples a modular male plug to a printed circuit board. The jack features a contact having a lower linear beam in combination with an glide dimple so that the contact can extend forwardly once its upward movement during mating with a modular plug is restrained. The lower linear beam is lifted during engagement and remains lifted while mated with a contact in a modular male plug. As a result of lifting, the free end of the contact also lifts in a typically unrestrained manner. However, the space above a mounted jack may be limited by multiple boards stacked in close proximity or the jack may be adjacent a mounting bracket located around the jack. If the space above the jack is limited, the contact will only be able to lift to a height less than its unrestrained lifted height. In one embodiment, the glide dimple is an arcuate shape whose open side faces downward so that its uppermost curved surface is tangent to the underside of the cover or upper wall of the modular jack. As the cover lifts in concert with the free end of the contact, when the cover hits a physical stop and thus is restrained from further lift, the glide dimple slides forward along the underside of the cover. The contact extends forward as the contact in the male plug lifts the lower linear beam further to a fully mated position so as to absorb the additional lift via extension in a direction generally parallel with the lower linear beam.
