Tandem Circuit Cards

摘要

An extension module 40 is provided for tandem connection to a base circuit card 1 having an external sheet material jacket 4 girding said card. The module includes a module housing 4a, 4b and a pair of spaced apart parallel support fingers 45 extending from the housing. The outer sides of said support fingers are configured for slidable insertion into corresponding spaced apertures 50 in the rearward end of the base circuit card to engage inner surfaces of the jacket adjacent opposite side edges of the jacket of the card. An electrical connector 49 is located between the support fingers and is adapted for mating connection with a corresponding electrical connector 3 located at the rearward end of the base circuit card, when the extension module is connected to the base circuit card. When the extension module is connected to the base circuit card by substantially full insertion of the support fingers into the base circuit card the engagement of said jacket embracing the fingers rigidly joins the extension module to the base card to form an integral extended circuit card.
