Abstract

There is shown and described a technique for mounting, locating and restraining circuit boards in a printer base plate, requiring a minimum number of parts. The bottom cover 2 of a device is provided with molded-in parts for receiving and retaining circuit board 3. Molded guides 4 include slots through which card 3 slides. Base plate 2 includes a molded U-shaped receiver 6. Receiver 6 is provided with cross pieces 8. These pieces 8 are adapted to enter cutouts 10 in circuit board 3 through entrance channels 14. Card 3 is automatically locked in position because guides 4 are positioned off-center relative to cross pieces 8 so that cross pieces 8 are wedged into the side of openings 10, as shown in Fig. 2. Cards may be removed by urging them rightwardly while lifting.

Molded Circuit Board Restraint

There is shown and described a technique for mounting, locating and restraining circuit boards in a printer base plate, requiring a minimum number of parts. The bottom cover 2 of a device is provided with molded-in parts for receiving and retaining circuit board 3. Molded guides 4 include slots through which card 3 slides. Base plate 2 includes a molded U-shaped receiver 6. Receiver 6 is provided with cross pieces 8. These pieces 8 are adapted to enter cutouts 10 in circuit board 3 through entrance channels 14. Card 3 is automatically locked in position because guides 4 are positioned off-center relative to cross pieces 8 so that cross pieces 8 are wedged into the side of openings 10, as shown in Fig. 2. Cards may be removed by urging them rightwardly while lifting. This particular configuration is advantageous in convection-cooled devices since air flow is not blocked; the flow of air through holes 12 in base 2 is restricted only by U-shaped receiver 6.
