Module for an integrated circuit system

Abstract

A module containing an integrated circuit, such as a read-only memory (ROM), includes an essentially box-shaped plastic housing having an internal chamber in which the integrated circuit is located. Positioned within the chamber is a printed circuit board on which the integrated circuit is mounted. Also mounted on the printed circuit board and adjacent to an elongated narrow slot located in one side of the housing are a plurality of electrical spring contacts electrically connected to the integrated circuit by means of electrical conductors on the printed circuit board. Upon insertion of the module into an electronic apparatus, edge connectors of a printed circuit board of the electronic apparatus extend through the narrow slot and engage the electrical spring contacts, thereby electrically connecting the integrated circuit to the apparatus. The module is designed so that its insertion into and removal from an electronic apparatus is by way of a receptacle which houses the battery power supply for the apparatus. This arrangement requires that the batteries be removed and thus the power disconnected, before the module is insertable into or removable from the apparatus to prevent damage to the integrated circuit from insertion with power on.
