Abstract: An extension module is provided for tandem connection to a base circuit card having an external sheet material jacket girding said card. The module includes a module housing and a pair of spaced apart parallel support fingers extending from the housing. The outer sides of said support fingers are configured for slidable insertion into corresponding spaced apertures 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 is located between the support fingers and is adapted for mating connection with a corresponding electrical connector 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.
