Backward compatible extended USB plug and receptacle with dual personality
First Claim
1. An extended Universal-Serial-Bus (USB) socket comprising:
- an extended socket pin substrate made of non-conducting material, having an upper socket-substrate portion and a lower socket-substrate portion forming a cavity between, the cavity being an opening sized to accept a standard connector pin substrate or an extended connector pin substrate, where the standard connector is a standard USB connector plug, wherein the extended connector is an extended USB connector plug;
an extended socket metal cover that partially surrounds the extended socket pin substrate, wherein an upper gap between the upper socket-substrate portion and an upper portion of the extended metal cover is sized to accept a standard connector metal cover or an extended connector metal cover, the extended socket metal cover having an opening to allow the standard connector pin substrate or the extended connector pin substrate to fit through when being inserted into the cavity;
standard metal contact pins, mounted on the upper socket-substrate portion, located to make physical and electrical contact with metal contact pins of the standard connector when inserted; and
extended metal contact pins, mounted on the socket pin substrate without making physical and electrical contact with the standard connector metal cover and the metal contact pins of the standard connector when the standard connector is inserted,wherein the extended metal contact pins make physical and electrical contact with metal contact pins of the extended connector when the extended connector is inserted.

Abstract
An extended Universal-Serial-Bus (USB) connector plug and socket each have a pin substrate with one surface that supports the four metal contact pins for the standard USB interface. An extension of the pin substrate carries another 8 extension metal contact pins that mate when both the connector plug and socket are extended. The extension can be an increased length of the plug'"'"'s and socket'"'"'s pin substrate or a reverse side of the substrate. Standard USB connectors do not make contact with the extension metal contacts that are recessed, retracted by a mechanical switch, or on the extension of the socket'"'"'s pin substrate that a standard USB connector cannot reach. Standard USB sockets do not make contact with the extension metal contacts because the extended connector'"'"'s extension contacts are recessed, or on the extension of the connector pin substrate that does not fit inside a standard USB socket.

7. An extended Universal-Serial-Bus (USB) connector plug compatible with an extended USB socket and a standard USB socket, the extended USB connector plug comprising:
-
an extended pin substrate that has an extended length that is longer than or equal to a standard length of the pin substrate of the standard USB connector plug; plug standard metal contact pins on the pin substrate, wherein, when the standard pin substrate of the extended USB connector plug is inserted into a cavity of the standard USB socket, the plug standard metal contact pins make physical and electrical contact with socket standard metal contact pins on a socket pin substrate; and plug extended metal contact pins on the extended pin substrate, wherein when the extended pin substrate of the extended USB connector plug is inserted into a cavity of the extended USB socket, the plug extended metal contact pins on the extended pin substrate make physical and electrical contact with socket extended metal contact pins on the extended USB socket, wherein the plug extended metal contact pins make contact when the extended USB connector plug is inserted into the extended USB socket, but do not make contact when inserted into the standard USB socket, wherein the plug standard metal contact pins carry standard USB signals during an initialization phase after receiving a switch command sequence to switch to an extended mode, wherein the plug standard metal contact pins carry extended-mode signals after the switch command sequence is received, and wherein the plug extended metal contact pins carry the extended-mode signals after the switch command sequence is sent over the standard metal contact pins. - View Dependent Claims (8, 9, 10)
