Microsoft has so far resisted attempts to move to USB-C on Surface tablets, possible due to the real security and durability benefits of the magnetic surface contact and possibly the additional revenue generated by having proprietary accessories.
However, there is considerable pressure to support the increasingly prevalent standard, which may explain Microsoft's latest patent, deceptively called MAGNETIC ACTIVATED LATCH MECHANISM. The invention uses magnets on each end of the cable and plug ( yellow in the picture above and
. The invention would as standard have a locking clip (456) in the cable that would hold a conventional USB C-cable in place, but when a special magnetic USB-C port is brought closer, it will pull the magnets (440) into the springs (438) which will allow the locking lock (456) to loosen, resulting in the cable only b The magnetic force between magnets 440 and 430 keeps it in place.
In this way, the particular magnetic cable, such as current surface couplings or Apple's old Magsafe cable, will disconnect and be detachable without damaging the connector or pulling the table. on a table if you pull over the cable. On the other hand, a regular USB-C cable will still continue to work as usual, including remaining firmly attached as expected.
The patent was filed in May 2018 and published for some days ago, so it might be an idea Microsoft works actively.
