Abstract: Disclosed is an electrical card guide or edge connector for mechanically and electrically connecting two printed circuit boards. The connector has an elongated body with an insertion slot at the top for receiving a circuit board and having mechanical snap-type fasteners at the bottom for mechanically securing the connector to a base board. Cross slots are provided in the connector body to receive contacts which are exposed in their mounted positions but which lie within the peripheral profile of the connector body in its fastened position. The contacts are configured with a U-shaped base portion permitting the contacts to be assembled by lateral movement onto the connector body for automatic locking action to secure the contacts into assembled position. The profile of the connector body has a height lower than its width. Pins are provided for locking the mechanical fasteners.
