Abstract: A part of an electric contact is specified, which is formed from a sheet, is constructed in the shape of a box, has at least four side walls and is assembled in such a way that there is located in one side wall a seam a which opposite edges of the sheet abut one another. The opposite edges are of counterbalanced configuration, and two projections are provided on the edge, and two recesses on the edge. A depression in the shape of half a spherical cap is located on the edge between the recesses. Depressions in the shape of half a spherical cap are arranged on the edge in the projections. The arrangement is intended to prevent the two edges from overlapping by virtue of a lateral effect of force.

Abstract: A panel mounted electrical connector is disclosed in combination with an equipment rack, multiple units of electronic equipment arranged in the rack, each unit having a connector in mating engagement with the connector mounted on the back panel of the rack. The panel mounted connector is arranged to align and hold in proper position multiple connectors, thereby forming a composite connector that mates with a mating composite connector on the unit of electronic equipment. Cutouts are provided in a surface of the composite connector so that cabling that is terminated to the connector may exit the connector at right angles thereto substantially parallel with the back panel.

Abstract: A connector is provided whose plastic housing includes downwardly-depending pegs for insertion in a circuit board to hold the connector in place, which provides for secure holding of the pegs in the circuit board holes by merely pressing the connector down into place. A spring clip (32, FIG. 2) is mounted on each peg, each clip having outwardly-bowed arms (36, 38) whose middle can press against the walls of the circuit board hole (14) to securely hold the peg in the hole, and whose lower ends are supported by the peg.

Abstract: A novel adapter for interfacing vintage oil fuse cutout devices with modern high-voltage cable terminations embodying a modern-standard bushing well at one end and a conductive member for mating with a cable entrance terminal of the cutout at the other end, and with mechanical (threaded) coupling to the device.

Abstract: A connector is made up of a connector housing including terminal accommodating chambers each of which has a first flexible locking piece for locking a metal terminal; and a terminal locking member which is engaged with the connector housing temporarily and finally, and which has second flexible locking pieces provided for locking the metal terminals in the terminal accommodating chambers, respectively. Each of the second flexible locking pieces has a locking protrusion which, when the metal terminal is inserted in a reverse way, is engaged with the protrusion of the metal terminal, or each of the second flexible locking pieces is adapted to push, when the metal terminal is inserted in a reverse way, the metal terminal against the wall of the terminal accommodating chamber, to interrupt the insertion of the metal terminal. Each terminal accommodating chamber may hve a terminal guide to smoothly guide the metal terminal thereinto.

Abstract: An electrical connector includes a socket housing (3) having a mounting portion (8) to be mounted on a metallic panel (50), and outer and inner tubular portions (6,7) extending forwardly from the mounting portion to form a plug fitting recess (12) between them; a lock recess (13) formed on the outer tubular portion for engagement with a lock arm (45) of a connector plug (2); a contact terminal assembly (4) inserted into the inner tubular portion and having a shield jacket (24) around the contact terminal assembly, the contact terminal assembly comprising an insulation body (27) and a ground plate (30) mounted on the mounting portion such that a shield terminal (39) with a contact portion (40) is brought into contact with the shield jacket within the terminal housing.
