Abstract
An internal rotational locking device prevents separation of a front cover and a rear cover of a user device. The internal rotational locking device includes a rotational bracket coupled to the rear cover. The rotational bracket includes a locking tab to overhang a locking edge of the front cover. The internal rotational locking device further includes a compression spring to maintain a distance between the rotational bracket and the rear cover. The internal rotational locking device further includes a torsion spring to maintain a first rotational position of the rotational bracket, where the locking tab overhangs the locking edge in the first rotational position.
