Abstract

An apparatus for conveying signals between a communications card and a signal utilization device or network. In one form (FIGS. 1,2), structures are provided for receiving one or more RJ series plugs and for making electrical connection with at the contacts on the plug and conveying any signals on the contacts to a communications device such as a telephone, facsimile machine, modem, or a local area network adapter. A body (102) includes one or more recesses (106) which receive the plug. An expandable and stretchable membrane (114) isolates the contacts in the plug from electrical contact with an object in a surrounding environment such that passage of current from one or more of the electrical contacts to an object present in the surrounding environment is prevented. Also provided (FIGS. 7, 14) is a replaceable direct access arrangement (151, 258) which is replaceably held within the communications device (150, 250). Both the structures providing the receptacles and the direct access arrangement are easily removable in case of damage or if other functions are desired. The replaceable direct access arrangement allows operation in countries having different telecommunications standards and allows operation with many different communications devices. Alternative structures for allowing connection to RJ series plugs are described. Wireless communication structures are also described.
