Modular enclosure elements employing cams forming detent features with latches

摘要

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.

主权项

1. A modular element removable from an enclosure during an unlocked mode and secured in the enclosure during a locked mode, the modular element comprises:
a chassis body supporting electronic components; at least one latch in pivoting communication with the chassis body and configured to engage the enclosure during the lock mode; and at least one cam in pivoting communication with the chassis body and each including a shape having a catch cam extending in one direction and a cam arm extending in another direction, the catch cam and the cam arm are configured together to form a detent feature with the at least one latch during the lock mode, wherein the detent feature secures the at least one latch with respect to the chassis body, wherein the at least one cam includes an actuating surface configured to receive a disengagement motion that results in the cam arm slidably engaging the at least one latch in a manner that moves the at least one latch relative to the chassis body to facilitate the disengagement of the chassis body from the enclosure.
