ABSTRACT:
An anti-slamming latch is described for removably installing a module housing into a bay in a frame having a predetermined width. The module housing has a guide pin on a front portion thereof projecting from said housing. The latch apparatus comprises a latch body supported from the frame allowing straightforward removal and insertion of a rear portion of the module housing into said bay. The latch body has a first channel therein adapted to receive and engage the guide pin when the body is in a first position. This channel has a closed end engaging the pin to prevent insertion of said module housing past a predetermined intermediate position in the bay. The latch body has a second channel intersecting the first channel forming a rounded protuberance therebetween.
The module may not be further inserted by pushing on the module. It may only be fully inserted in the bay by moving the latch body from the first position to dislodge the pin from the closed end of the first channel, move the pin over the rounded protuberance, and into the second channel in the body. Movement of the latch body levers the pin along the second channel, and thus the module into full insertion, to a second closed position wherein the pin is fully within in the second channel in the latch body.
