    Abstract: A connector for use with printed circuit boards is described. For use with boards having contacts arranged, for example, along an edge, the connector has a number of spaced apart flexible conductive rings supported on a common elastomeric core. The rings make contact with the board contacts and, through corresponding contacts of at least two boards, provide external interconnections between boards. The connectors may be supported by an internal support, such as a reinforcing rod, or they may be located by, for example, recesses formed in their ends. The rings are preferably very thin walled to provide flexibility, the necessary mechanical support for the rings being provided by the core. To produce rings having a sufficiently thin wall, a thicker-walled tube may be internally etched to reduce the wall thickness to the required dimension.
