So far, Microsoft has refused to try to use the USB-C fast charger interface on its Surface tablet, probably because of the true security and durability advantages of the magnetic Surface charger. And may be due to additional income from this patented accessory. However, compatibility with the popular USB-C interface standard puts tremendous pressure on Microsoft, which may explain Microsoft’s latest patent, which is named the magnetically activated latch mechanism.

Patent documents show that Microsoft uses magnets on both ends of cables and plugs and is compatible with conventional USB-C cables.

There is a locking latch (456) in the cable that holds the conventional USB-C cable in place, but when the special magnetic USB-C port is close, it pulls the magnet (440) into the spring (438) which will allow The locking latch (456) is disengaged so that only the magnetic force between the magnets 440 and 430 is used to hold the cable in place.

This special magnetic cable is somewhat similar to Apple’s Magsafe cable, can be connected without any insertion force, and can be removed without damaging the connector, Pulling the cable will not drag the entire machine off the table. In the face of the conventional USB-C interface, you can continue to work as usual, including continuing to maintain a strong connection. The patent was filed in May 2018 and was disclosed a few days ago, and we should see it in Microsoft products in the future.
