New smaller USB Type-C connector to replace Type-A and Type-B

New smaller USB Type-C connector to replace Type-A and Type-B
(Phys.org) —The USB Implementation Forum has announced at the Intel Developer Forum in China, that the proposed Type-C USB connector has been approved—it will be finalized later this summer with products using the new standard out, likely before the holiday season. It is intended to replace both the Type-A and Type-B USB connector.

The USB (Type A and B) port has been with us now for a long enough time that we've all become numb to its imperfections—cords have to be plugged right side up and the right end into the right device. All that is about to change now as the new cords will have identical connectors on both ends and can be plugged in regardless of orientation.

The Implementation Forum first began considering the changeover this past December—now just four months later, they've come to a decision. The only drawback to the new connector standard appears to be a lack of backwards compatibility.

USB Type-C will be much smaller than the current standard, though not as small as the micro sized cable connectors used on many smartphones. Whether device makers will deem it small enough for phones and tablets remains to be seen. Also, there appears to be a very good chance that computer makers will retain some of the old standard ports and simply add some of the new as well, making sure consumers can use either if they so choose.

In addition to its small size (just 8.3x2.5mm) the new standard will also allow for the maximum USB 3.1 specification throughput rate of 10Gps (and still allow for higher rates in the future). Also, in another nod to user complaints, the new connectors will make an audible click when fully inserted. Certified plugs must also be able to last up to 10,000 plug/unpluggings. One small challenge for the new standard will be a renewed push by some in the industry to settle on a wireless USB standard, which could at some point make all cable USB connectors moot.

The new standard isn't likely to revolutionize the , but it will almost assuredly bring smiles to the faces of those in the future remembering the ire at having to make several attempts at simply plugging in a device with the old cable

Yes, getting rid of unhandy USB connectors and replacing them with one, easy and simple to use connector is amazing.


The only worry is that it's too small to be reliable. Regular USB-A connector is pretty rugged, whereas the micro connectors are flimsy and feel like you could just yank the whole socket off the board or snap it if you accidentally pull on the cord the wrong way.

Things like USB bluetooth of wifi adapters fit almost entirely inside the USB-A connector, whereas with a micro size connector you would be left with a protruding dongle hanging off the side of the laptop on a thin piece of metal that surely can't take very much mechanical stress.

Looks very, very flimsy. I've had problems with the weeny plugs on digital camera interface cables working loose. Bad enough for data transfers, but when you come back to find an essential charge cycle was lost at ~ 10%, you have a problem.

How will it handle the weight of its own cable ? Or the weight and size of a USB stick or widget ??

I had to get short AM/AF 'pigtails' to avoid leverage on my PC's USB sockets after incautiously leaning across case and knocking a memory stick...

As someone who began his career wiring and troubleshooting RS232 connectors with a $250 breakout box filled with dazzling red and green LED's, I think the current USB connectors are just fine as they are. If someone is having that much trouble figuring out how to orient them, then perhaps they should move to the wilderness and master the art of creating useful tools from flakes of stone.
