USB Reversable Cable Images Emerge

Lucas123 writes: "A presentation released today by Intel revealed images of the USB 3.1 Type-C cable and connectors, which is symmetrical and will no longer require a user to correctly orient the plug. Initially, the USB 3.1 Type-C specification will support up to 10Gbps data transfer speeds. The Type-C connectors resemble those of Apple's Thunderbolt cabling in that they are much smaller than today's USB SuperSpeed connectors. The receptacle opening is 8.3mm x 2.5mm.The first iteration will have a 5 volt power transfer rate, but it is expected to deliver up to 100 watts for higher power applications in the future."

      The problem with MicroUSB and even full-sized USB is that stupid tongue in the middle of the socket that goes inside the plug on the cable. That tongue can be easily broken by moving the device with the cable plugged in. I've snapped that off a phone and a desktop now. And there's no way to fix it without replacing the entire socket ... not easy when it's soldered to the motherboard.

      The Lightning socket/plug is going in the right direction. The contacts should be on the outside of the plug on the cable, and along the inside walls of the socket. The plug should be solid (no holes), and the socket should be just a hole (no pins, tongues, or whatnot).

      Compare the headphone jack/socket. Connectors around the inner wall of the socket and on the outside of the plug. Plug is solid. Socket is a hole. Impossible to plug it in wrong. Take design cues from that, from the Lightning connector, hell even the old mini Christmast lights got it right.

      Pins and tongues inside of sockets that a plug has to go around is just dumb. Didn't we have enough issues with bent pins on VGA/Serial/Parallel/PS2 ports to realise that was the wrong way to do things?

  52. USB B plug is D shaped by sjbe · · Score: 1

    A D-shaped connector - instead of a square one - would not have cost any more, and would have eliminated a LOT of frustration over the past 18 years.

    The USB B plug is D shaped and it's just as annoying as the A plug. In fact instead of 2 possible orientations to choose from I have 4 with the B plug.

    That's the RCA connection. Composite is the standard, RCA is the connector. Component is technically RCA as well, but I consider it a bit different because you need 3 of them.

    My iPhone 5 connector is no longer reliable. Half the time it is plugged in and the iPhone does not get charged. Tolerances are tight on the tiny thing and its socket loosens up with time, allowing just enough play to disconnect if the phone is even breathed on. 2-sided, yes. Bipolar would be a better description.

    MagSafe patent should never have been issued. I have a ten year old water heater with a MagSafe connector. It falls out if it gets bumped instead of the water heater falling off the table and spilling hot water all over everything.
