Abstract

Abstract A support assembly for a printed circuit (PC) module card comprises a pair of elongated metal channels and respective thermoplastic liners. One end of each channel is mounted around the respective end of a plate-mounted cardedge receptacle by means of guide and locking fingers which extend through apertures in the plate and lock the channel thereto. The rest of the channel extends upwardly to provide an insertion guide and mounting support for ''''tall'''' module cards. The lower end of each liner is inserted between the bottom portion of the channel and the end of the receptacle to rigidify the channel. Near the top of each liner is a boss which fits into a mating hole in the channel and at the upper end of each liner is a shoulder which mates with a respective shoulder on the channel, thereby releasably to lock the liner to the channel. The liner insulates the card from the channel and insures a tight fit between the card and the channel.
