Locking USB Cords
Pinch the sides on the USB type A plugs to insert them; they lock in place to prevent the cord from detaching. Shielding blocks signal interference from nearby equipment and devices. These cords are backward compatible, so they work with cords and connectors that meet the same or lower USB standard.
A plug × A plug cords lock on both ends.
A plug × B plug cords lock only on the type A plug end.
