  • Patent number: 3964813
    Abstract: A connector for connecting 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 conductive, 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 of the conductor. The conductor has a slightly larger outside diameter than the diameter 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 connection between the circuits.
