USB Type-C Next Generation Connector Design Revealed

The USB connector as we know it today has been with us since the mid-to-late 1990s. The things we find on the other end of those USB connectors are radically changed in the past decade; we wouldn't have even imaged charging our smartphones from our computers using the USB cable. Now it's time for USB to modernize itself with the rest of the industry. The USB-IF today unveiled renderings that show what the new Type-C connector will look like.

Announced late last year, USB Type-C will have the handy feature of being reversible, meaning that you'll never have a failed connection again for plugging it in upside down.

Design Characteristics

Entirely new design
•          Tailored for emerging product designs
•          Robust enough for laptops and tablets; slim enough for mobile phones

New smaller size
•          Similar to size of USB 2.0 Micro-B
•          Listen for the “click”

Usability enhancements
•          Reversible plug orientation & cable direction

Supports scalable power charging

Future Scalability
•          Designed to establish future USB performance needs


Mechanical specs (preliminary):
•          Receptacle opening: ~8.3mm x ~2.5mm
•          Durability: 10,000 cycles
•          Improved EMI and RFI mitigation features

Power delivery capacity:
•          3A for standard cables
•          5A for connectors

Functional capabilities:
•          USB 2.0: LS/FS/HS
•          USB 3.1: Gen1 (5Gbps)/Gen2 (10Gbps)

Enhanced power delivery options:
•          Extended 5V current ranges plus USB PD

Docking support:
•          USB PD-based interface configuration option

Keep in mind that these are just the early planned specifications. The final specs for USB Type-C are expected to be published sometime in July 2014.

    Looks ok to me. Whats this "Listen for the 'Click'". I'd rather have feedback I can feel.

    The EU has passed a law stating all phones (including Apple) must use the same charging cable by 2016 (i think). I heard Apple, Samsung, Nokia, HTC.etc were taking part in the design process as well. I wonder if this is the design that will be used, it being reversible being the key thing Apple was pushing for, or whether we will see a proprietary USB phone connection

    Any word on how many pins are in there? Previous reports said that they would have more than the current 9 for future-proofing.
