Electronic device having a dual key connector
First Claim
1. An electronic device having an electronic connector, the electronic connector comprising:
- a keying arrangement having first and second sets of keys, the first set of keys being spaced apart by a first length and the second set of keys being spaced apart by a second length different than the first length; and
a plurality of contacts including first, second and third ground contacts, first and second power contacts, an accessory power contact, a USB power contact, a plurality of USB signal contacts and left and right audio out contacts;
wherein when the electronic connector mates with a corresponding second connector associated with an accessory device, at least one of the contacts is active and the first, second and third ground contacts make contact with ground contacts in the second connector before the accessory power contact makes contact with an accessory power contact in the second connector.

Abstract
A connector interface system for a communication device is disclosed. The interface includes a docking connector. The docking connector includes first make/last break contacts that minimize internal damage to the internal electronics. The docking connector also includes specific keying arrangement to prevent noncompliant connectors from being plugged in, and thereby minimizes potential damage to the multi-communication device. The connector interface system also includes a remote connector which provides for the ability to output audio, input audio, provides I/O serial protocol, and to provide an output video. Embodiments of the present invention allow for a standard headphone cable to be plugged in but also for special remote control cables, microphone cables, video cables could be utilized in such a system. The connector interface system also includes a serial protocol to control device features. These controls help a user sort and search for data more efficiently within the device.

34. An electronic device having an electronic connector, the electronic connector comprising:
-
a keying arrangement having first and second sets of keys, the first set of keys arranged at a top of the connector and spaced apart by a first length and the second set of keys arranged at a bottom of the connector and spaced apart by a second length different than the first length; and a plurality of contacts including first, second and third ground contacts, first and second power contacts, an accessory power contact, a USB power contact, a plurality of USB signal contacts and left and right audio out contacts; wherein the accessory power contact provides power out at a first power level and the first and second power input contacts receive a power in at a second power level that is higher than the first power level; and wherein the ground contacts are longer than the accessory power contact so that when the electronic connector mates with a corresponding second connector associated with an accessory device, the ground contacts make contact with ground contacts in the second connector before the accessory power contact makes contact with an accessory power contact in the second connector. - View Dependent Claims (35, 36, 37, 38)
