Open the CIPO recordAbstract From the Canadian patent
A connector for circuits located on different layers of a multilayer printed circuit board through a hole in the board. The connector is a hollow cylindrical conductor made from a metallic, springy material. A slit in the conductor and a plurality of sharp teeth located on the outside of the conductor extend the full length thereof. The conductor has a slightly larger outside diameter than that of the hole. Consequently when the connector is forced into the hole the, springback (resiliency) of the connector forces the teeth against the circuits on the printed circuit board thereby providing a positive contact.
