US Patent 11425838 Swappable electronic device and shelf systems

An electronic module, such as a power module, may include a latch having two or more protrusions where a first protrusion can fix the electronic module into a shelf and the second protrusion can be a curved protrusion that activates the latch when an adjacent electronic module is inserted into or removed from the shelf. In some embodiments, a third protrusion may be included, where the first protrusion and the third protrusion both fix the electronic module to the shelf and are activated by the latch. Also, a shelf may include a partition between two electronic module receptacles that has a width that is less than a protrusion extending from a side wall of one of the electronic modules.
