The invention is a shaped base plate assembly onto which one or more separate units may be detachably mounted. One common latch plate, bolted to the base plate, fixes all the separate units in place in fixed relation to each other and to the base plate. The invention may be employed to mount four separate transformers to a common base plate. Each transformer is fitted with appendages such as four cylindrical legs, each leg being shaped with a circular undercut of reduced cross-section adjacent the free end of the leg. The base plate is formed with sets of keyhole-shape or teardrop-shape holes, with each set of holes located to accommodate the legs of a given transformer. When all four transformers have been inserted and then slid into the latched position, a latch plate is fastened by one latch screw to the base plate. The latch plate is of a shape and size to abut against at least one leg of each transformer and to bias the undercut section of each transformer leg snugly against an edge of a base plate hole. By preventing each transformer from being slid towards the latch plate, the undercut section of each transformer leg is latched in place against the edge of a base plate holes, and all four transformer units are held in place on the plate. The latch plate may be slidably mounted to the base plate and shaped so that it does not abut against the transformer legs when slid to an unlatched position and conversely abuts firmly against at least one leg each of a pair of mounted transformers when slid into a latched position.

Slide lock mechanism

The invention is an enclosure for containing several printed circuit boards. Detechable brackets for mounting the enclosure to a rack, detachable latching door hinges and a combination of detachable members are assembled in an improved housing for detachably enclosing mounted printed circuit boards and other modular components and includes a base, a cover having a top and depending sides provided with slots; and vertical card guide brackets and a pivotable door. These detachable members are formed so as to to latch together into an integral assembly. The door when pivoted to the open position is held as a tray in the horizontal plane of the base and does not drop below the base, with a peripheral rim of the door serving as sides of the tray.
