Abstract:
A low profile contact means stamped from a section of flat stock material and comprising an incomplete cylindrical portion having a C-shaped cross-sectional configuration and further having a flanged portion at one end thereof. A terminal pin extends from the other end of said cylindrical portion. The contact is inserted through an aperture in a printed circuit board with the flanged portion seated on the surface of said circuit board. A tang formed from the cylinder wall extends downwardly into said cylindrical section and towards the gap created by the incomplete cylindrical section. A male pin inserted in said cylindrical section will be pressed by said tang into said gap in said cylindrical section and against the wall of the printed circuit board aperture.
Abstract:
A method and machine is provided to serially supply a plurality of workpieces to a work station where each workpiece is individually subjected to a forming operation that conditions the workpiece for an interference fit when inserted within an aperture of a workpiece holder such as a card or printed circuit board. Each workpiece is individually and sequentially subjected to the forming operation, then segregated from the remaining workpieces and precisely positioned for automatic insertion into the apertured card or board by a transfering mechanism. The occurence of a malfunction in the automatic insertion operation will automatically shut off the machine enabling correction of the malfunction.
Abstract:
A wiring machine for bridging a discrete length of electrical wire between selected point-to-point locations of a printed circuit board and a mechanical analogue computer used to compute the length of wire required to bridge between the point-to-point locations. The machine includes a table which carries the printed circuit board for displacement along each of two orthogonal axes. The computer is responsive to displacement of the table and includes a system of gear trains for driving a wire feeding mechanism to feed a discrete length of wire corresponding to the length of table displacement along either of said orthogonal axes. When said table is diagonally displaced with respect to the orthogonal axes, the computer will drive the wire feeding mechanism to provide a length of wire equivalent to the length of such diagonal displacement, thereby providing discrete point-topoint wiring on the printed circuit board.
