Electronic device with circuit board latching and retaining structure

Abstract

An enhanced accessibility router includes an outer housing with a side wall opening through which a support tray man be inserted into the housing interior and removed therefrom. A variety of printed circuit boards, including a system I/O board, a CPU card, and various option cards are mounted on the tray for movement therewith. At the back end of the support tray is a specially designed latch and card support member which functions to releasably hold the tray in an outwardly withdrawn position thereof and to receive and support edge portions of the CPU card and option cards. The CPU card is captively retained on the tray by an elongated card retaining member that may be quickly and easily installed on and removed from the tray without tools. A front housing wall has an opening disposed therein and facing a PCMCIA card support structure mounted on the inner end of the support tray. When the tray is fully inserted into the housing interior the PCMCIA card support structure enters the front housing wall opening and is positioned to receive a PCMCIA card inserted rearwardly therethrough. Accordingly, access to the PCMCIA card support structure is provided through the front side of the housing when the tray is fully inserted, and from the rear side of the housing when the tray is pulled outwardly from the housing.
