USB 3.1: Intel’s new type C connector


In the context of the Intel Developer Forum 2014, the chipgigant had introduced a new USB port, Apple now also installed it in its new MacBooks and even goes so far as to forgo the new models on all previous interfaces and connect them with a single connector of the new Type. All data (video, I / O and so on) as well as the required current are entered into the device via this connection. If multiple devices are to be connected at the same time, customers will have to resort to adapters or docking stations in the future – a finding for the accessories industry.


We had already reported on the type C connection in December 2013. It supports USB 3.1 and is smaller than all previous USB plugs and sockets. The opening of a Type C socket measures only 2.5 by 8.3 millimeters. In addition, the edges are rounded, which makes them easier to insert.

In addition, Intel and the USB consortium have probably been inspired by Apple’s Lightning port. As with the proprietary cupertino connector, it will not matter how plugged into the corresponding socket for Type C connectors. This should also simplify the handling of the plug.


Thanks to the new USB 3.1 standard, data transfer rates of up to ten gigabits per second should be possible. Type C connectors also support the 2011 USB A / V standard for the transmission of sound and images. In addition, the new plug will allow more power to be transmitted than the USB standard so far. Devices connected via USB 3.1 therefore do not require any additional power supply in the ideal case. There is probably no one to complain about less than a few cables.


The new Usb type C plug could become the standard for smartphones and tablets in the long term. This would make the handling of the USB connectors much easier. But of course, type C ports – as Apple has now shown – could also be installed directly into computers and other peripherals.
