  • Patent number: 4570338
    Abstract: A screw terminal (14) is formed on a circuit board (12) by inserting a typical terminal screw (22) in a thread-forming operation into a tube (27) of a rim-like seat (21). The screw (22) is inserted into the tube (27) to a predetermined depth which is equal to or greater than the thickness of the circuit board (12). After the insertion of the screw (22) into the seat (21), the seat (21) is inserted into an aperture (16) in the circuit board (12). The aperture (16) is of circular cross section of a diameter such that the wall of the aperture engages the edges of the tube (27) in interfering contact. In a preferred embodiment, the wall of the aperture (16) is metallized and the seat (21) is of a copper coated, low carbon steel. After insertion of the seat (21) into the aperture (16), the seat (21) is soldered to the aperture (16) in an operation which fills any gaps between the circuit board and the seat and fixes the position of the walls with the confines of the circuit board.

  • Patent number: 4280746
    Abstract: A connector 10 (FIG. 1) is arranged with two hinged arms 30, 40 for protecting the terminations of electrical conductors 18 in the connector. Each of the two arms includes hood sections 31, 41, collar sections 32, 42 and clinching means 36, 46 arranged to mate with each other. As the arms 30, 40 are pivoted back over the termination end 21 of the connector, the clinching means 36, 46 mate with each other securely locking the collar section 32, 42 about the electrical conductors 18 thereby aligning the hood portions 31, 41 over the termination end 21 of the connector.
