Modular enclosure elements employing cams forming detent features with latches

Modular elements removable from enclosures and employing cams forming detent features with latches are disclosed. A modular element may include a chassis body supporting electronic components. The modular element is removable from or secured to an enclosure using a latch. The latch may engage the enclosure and may remain engaged with the enclosure by being secured by interfacing with a cam. By forming the cam with a predetermined shape, a detent feature may be established with the latch to secure the latch and maintain the modular element locked to the enclosure. The latch may be disengaged from the cam by applying a disengagement motion to the cam and allow the latch to move relative to the chassis body and disengage from the enclosure. In this manner, the modular element is efficiently secured and removed from the enclosure with minimum obstruction to airflow to the electronic components.
