  • Communication device having a coupler with a connection point
    Patent number: 6658275
    Abstract: A communication device (1) comprising a first part (2); a second part (3); coupling means (4) for coupling the first (2) and the second part (3) and allowing a mutual movement about a hinged joint (AA); and a connection point (5) for an insertable plug. Said point of connection (5) is arranged to said coupling means (4) and it substantially coincides with the hinged joint (AA) of the device (1). Consequently, the external connection will not interfere with the pivoting movement nor will it complicate handling and holding of the device.
