Abstract
Device modules of an electrical system are slidably fitted in an enclosure and integrated therein as a part of an air duct system for cooling the modules. Other modules such as air mover modules, for the air duct system, are also slidably fitted in the enclosure to move air in the air ducts and the device modules. Each module carries a pivotally mounted flat latch lever in a recess in a surface at one end of the module. A latch member on one end of the latch lever engages a catch member on the enclosure as the module approaches its fully inserted position. Movement of the latch lever to latched position, when the latch member and catch member are engaged, pivots the latch lever about the catch member and applies force to the module at the pivotal mount, to drive the module into its fully inserted position. The mechanical advantage provided by the latch lever minimizes the manually applied forces acting on the module which significantly reduces the likelihood of damaging any device within the module. Reverse pivotal movement of the latch lever about the catch member withdraws the module from its fully inserted position. The mechanical advantage provided by the latch lever minimizes …
