Abstract
Abstract An improved electrical connector for use in both a communications card or a communication or computing device for fusibly interfacing between a media connector and a downsized computer or communication device is provided. In a first embodiment, the communications card comprises a retractable access portion and a fixed portion. In a second embodiment, the fixed portion is a communication or computing device without an intermediary communication card. The retractable access portion has an aperture formed therein configured to receive the media connector. A fusible link is formed by a fusible pin block which includes a conductive terminal having a first and a second end mates with both the retractable access portion and the fixed portion. The first end makes electrical contact with the media connector while, simultaneously, the second end slidingly makes electrical contact with the fixed portion as the retractable access portion is extended beyond the computer housing during use. The conductive terminal has a fuse region within the pin block that can be formed by necking-down the conductive terminal to create a current restriction. Alternatively, a fuse material having fixed fusing characteristics may electrically bridge a first end portion and a second end portion of the conductive terminal. The fusible link protects equipments and persons from spurious electrical conditions introduced into the communications card via the media connector.
