  • Patent number: 4780095
    Abstract: An edge connector for electrically connecting and mechanically securing a daughter board to a mother board. The edge connector includes an insulator body with a pair of stalks spaced apart so as to accomodate a daughter board therebetween. The insulator body is provided with a number of contacts, each of which is housed inside a contact slot inside the insulator body. Each contact has a surface pressure contact area for electrically connecting to the mother board to which the edge connector is attached. Each contact also has a contact area that extends into the daughter board slot. The contacts are arranged so that in each pair of adjacent contacts one contact has an upper contact area and the other a lower contact area. The upper contact areas are located above the lower contact areas. This makes it possible to use a daughter board with two rows of offset contact pads with this edge connector.
