摘要

An identification system includes a mobile communications device and an accessory having a connection plug with a conical tip. An insulating ring extends about the conical tip portion to define a tip detection contact. The device includes a tip detection pin positioned adjacent to an interior end portion of a connection socket on the device. The tip detection pin engages the tip detection contact to enable identification of the accessory by the mobile communications device. An improved accessory is for use with a mobile communications device. A method identifies an accessory which has its connection plug inserted into a socket on a mobile communications device.
