Abstract: An electrical connector is attachable to an insulated electrical conductor wire and insertable partially through a hole defined through a printed circuit board after attachment of the connector to the wire in order to retain a bared end portion of the wire in a desired predetermined position between the sidewalls of the hole and substantially below the top surface of the board prior to the formation of an electrical solder connection between the bared end portion of the wire and an electrical conductor formed on the bottom surface of the board. The connector is comprised by a base having rearward and forward portions, a first pair of sidewalls extending outwardly from opposed longitudinal sides of the rearward base portion, a second pair of sidewalls extending outwardly from opposed longitudinal sides of the forward base portion, and a pair of resiliently flexible hook-like members projecting from the second pair of sidewalls.

Abstract: A free standing all metal contact, which, when mounted on a first board with other similar contacts, all in a straight line, will mechanically receive and hold, and make electrical contact with a second circuit board. Each contact has U-shaped configuration with the two legs of the U having a width which is normal to the plane of the U. The edges of each of the two legs are bent back in a direction away from the other leg to form an I beam type cross-sectional configuration to provide structural strength. Two of the bent back edges which are diagonally positioned are extended beyond the closed end of the U to form a pair of posts which fit into mating holes in the first circuit board to securely mount the contact thereon. The free end of one of the legs is bent downwardly into the U and towards the other leg to provide a spring-like gripping effect upon the edge of the second board when it is inserted into said U.
