USB 3.1: Intel announces new details on the Type C connector

Thanks to USB 3.1 and its new type C connector, the alignment issues are finally to be completed: Intel has introduced the new USB standard along with the appropriate type C connector on the IDF 2017, with which it no longer plays a role and

Up to now, Type A has been widely used for USB connections. In contrast, USB 3.1 is significantly more compact. With a width of approximately 8.3 millimeters and a height of 2.5 millimeters, the type C plug is only slightly larger than a USB 2.0 mini plug.

In addition, the USB 3.1 cable not only fits into the connector in either plug-in direction but also has the same connector on both ends of the cable.


In contrast to Apple's Lightning cable, which offers a similar function, the type C plug as in the previous connections, the contacts inside are hidden. Inside the socket is a centrally placed tongue, on both the top and the bottom of which there are contact strips with 12 contacts per side.


In addition, the electromagnetic shielding for USB 3.1 has been improved. This advantage was achieved by recesses on the collar. Nevertheless, the type C plug should be plugged securely into the socket: Two springs on the side of the tongue snap into place when connecting. This security has been enhanced by a metal core which is designed to run along the entire width, as well as the shield.


There are also advances in the endurance compared to older models. For example, both the jacks and the plugs should be able to withstand at least 10,000 plug connections with the USB 3.1 standard - about seven times more than with the type A plug. The lifetime of the new connector should be around 15 years.


Furthermore, the components should be more stable against distortions. Optionally, a clamp can also be attached to the bushing to increase the resistance force.


However, the speed of the new standard is not necessarily at the USB 3.0 level. Manufacturers are allowed to develop USB 2.0 cables with Type C connectors, which then contain fewer wires. Thus, the mode called "Superspeed +", with which transfer rates of up to 10 gigabits per second are possible, is no duty. However, a certification program should provide clarity.
