  • Patent number: 4226494
    Abstract: Disclosed herein is a circuit panel connector for electrically connecting a circuit panel, such as a printed circuit board, with an insulated wire. The panel connector comprises a one-piece connector body of dielectric material having a main portion and a cover portion. The main portion includes a socket for receiving the panel, a rear wall, a floor, a pair of spaced side walls ech unitary with the rear wall and with the floor and providing the main portion with a cell. The main portion also has an opening in open communication with the cell and the socket and each side wall has a corner provided with a projection having an eave confronting the floor. The cover portion is hingedly connected to the rear wall and is movable between an open position in which the cover portion does not cover the cell and a closed position in which the cover portion covers the cell. The cover portion also has latching and strain relief resilient projection means.

  • Patent number: 4221249
    Abstract: An elongated sleeve or tubular member is provided concentrically fixed about the shank of a screwdriver with the sleeve having an axially flexible section between its opposed ends to facilitate axial shortening of the sleeve when the screwdriver is used to rotate a fastener the head of which is captured within the open end of the sleeve proximal to the blade of the screwdriver. Such axial shortening of the sleeve automatically seats the screwdriver blade within the slot in the head of the fastener when the frictional force between the screw's threads and those of the tapped hole into which it is being driven overcomes the interference fit between the free end of the sleeve and the screw head.

  • Patent number: 4174147
    Abstract: A circuit panel connector for enabling the connection of a plurality of circuit terminals at the edge of a circuit panel, such as a printed circuit board, with external conductors includes a unitary block of dielectric material with an elongate slot and self-aligning unitary electrical contact members each having opposed tines for receiving the edge of the circuit panel and a terminal portion with a platform and a clamping screw for selectively securing an external conductor to the electrical contact member.

  • Patent number: 4099826
    Abstract: A dual orientation feed-through terminal block capable of being mounted selectively in either one of two orientations and including an electrical terminal member affixed in the block and having a contact extending through a slot in the block, the contact being permanently deformable into remains affixed in the block, to provide a feed-through in a direction appropriate to the selected mounting orientation.

  • Patent number: 4089612
    Abstract: An improved cylindrical interference fit for joining and fastening synthetic polymeric material connecting members comprises a smooth surfaced shaft and a complementary internally ridged recess. The shaft, during insertion into the recess, shears away the tips of two spaced longitudinal ridges positioned within an 180.degree. angular segment of the recess and bindingly engages the sheared tips and a portion of the internal surface of the recess thereby forming a three-point interference fit, interlocking joint between the joined members.

  • Patent number: 4027940
    Abstract: In an electrical connector of the type in which an electrical conductor is clamped between the end of a clamping screw and a clamping surface in an electrical contact member, a cup-like clamping jaw carried at the end of the clamping screw, the clamping jaw including a clamping base and a circumferentially continuous generally tubular wall having circumferentially spaced portions permanently deformed radially inwardly to capture the clamping jaw upon the clamping screw while enabling relative rotation between the clamping screw and the clamping jaw, and circumferentially spaced lobes projecting radially outwardly between the radially inwardly directed permanently deformed portions.
