Abstract: Through the wall hot and ground type stud connectors are disclosed for use being positioned through truck and other heavy duty motor vehicle battery box side walls, engine firewalls, dashboards and the like. The stud connector includes a unitary conductive connector element with opposed first and second male connector ends and a radially enlarged central segment therebetween. In the hot type stud connector an overmold insulative member extends around part of the enlarged central segment and has a face that abuts a surface of a wall member and an annular flange that extends through a wall aperture to insulate the connector from the wall. An insulative nut member has a face for abutting an opposing surface of a wall member. A complementary cylindrical recess in the nut member slidingly receives the annular flange for fitting through various thicknesses of walls. The ground connector has a smaller overmold insulative member with a face for abutting one surface of a wall member.
Abstract: A mating terminal structure includes a generally box-shaped female terminal defining a receptacle with a flexible cantilevered contact beam formed from a bottom wall thereof. The beam includes a radiused contact portion. A male terminal is insertable into the receptacle in a given insertion direction (A) and includes a contact cam for deflecting the cantilevered contact beam and engaging the contact portion thereof. The contact cam has a leading ramp surface extending at a relatively small acute angle relative to the insertion direction for engaging the contact portion and gradually deflecting the cantilevered contact beam. The contact cam also has a trailing locking surface extending at a relatively larger acute angle relative to the insertion direction for providing locking interference between the contact portion of the cantilevered beam and the contact cam of the male terminal to thereby removably lock the male terminal to the female terminal.
Abstract: An electrical contact has a general flat sheet metal support with a pad portion that is twisted (e.g., by about 90 degrees) out of the plane of the metal support, and a contact body attached to the pad portion. The contact may be made by welding a contact body on a pad portion of the contact support while the contact support is essentially in its original flat state; and using one progressive stamping die to isolate the pad portion, form a twist, and stamp out the contact, so that the pad portion is in a plane that is generally perpendicular to the plane of the contact support.
Abstract: The invention is a modular cross-connect system which has a connector block having an array of connector jacks therein and which is mountable on a panel. The block has pivot pins for pivotally mounting it in an aperture in the panel, and the rear of the block has connectors thereon for connecting wires or other signal carriers to the connector jacks. The block can be pivoted to give access to the connectors from in front of the panel so that connections can be made, after which the block can be pivoted back to its operative position and latched in place. In a second embodiment of the invention, the block is supported by retaining clips extending from the front of the panel so that it can be supported in front of the panel during wiring after which it is inserted into an aperture in the panel and pivotally supported therein, with means on the block for latching it in place.

Abstract: A pluggable male terminator for use with a female ribbon cable connector. The terminator is comprised of three basic parts that can snap together. The three members are a shroud having openings in the top, a PC board with pins extending from opposed surfaces, and a cover with recesses therein. The pins are complementary in shape and size to the openings in the shroud and the recesses in the cover. Further, the pins are aligned with the openings in the shroud and the recesses. For assembly, the pins on the PC board are inserted into the recesses in the cover openings in the shroud and the parts are pushed together. The pins extending from the shroud are adapted to be inserted into recesses in the female ribbon cable connector.
Abstract: A female connector and a male connector engageable with each other are paired. Fixing shafts are projected from both lateral sides of the male connector. The female connector has a retaining lever being pivotable about pivots arranged on both lateral sides thereof. Rail portions are arranged on a front surface of the lever, each rail portion having a predetermined surface of curvature. When the male connector is inserted into the female connector, shaft portions of the fixing shafts are abutted against the rail portions and bias the rail portions, so that the surfaces of curvature produce resisting forces, each having a component for pivoting the lever.
Abstract: A waterproof structure of a connector comprises a rubber waterproof plug (17, 61, 67, 71) engaged with a rear end portion (24) of a connector (23) for waterproofing of the connector, the rubber waterproof plug being formed with a plurality of wire insertion holes (27) through which wires (31) led out of the connector are passed under airtight condition. The plug is also provided with at least one non-used wire insertion hole (35) and with a waterproof plug cover (19, 63) also engaged with the rear end portion (24) of the connector for covering the rubber waterproof plug, the waterproof plug cover being formed with a plurality of wire leading holes (45) through which the wires (31) passed through the wire insertion holes (27) are led out to the outside.
Abstract: The locking lever of a detachable electrical plug connection can be produced cost-effectively and makes it possible to lock the plug connection securely. The locking lever is manufactured completely from a sheet-metal part, first guide elements, by means of which the locking lever is mounted on a plug housing such that it can rotate, being produced on the one hand, and second guide elements, by means of which the locking lever engages in guide tracks of a plug receptacle, being produced, for example via a deep-drawing or thermoforming process on the other hand. For functionally secure guidance of the locking lever, the first guide elements preferably have stamped projections as an axial withdrawal protection device, which secure the position of the locking lever even when forces are applied in this position which are directed transversely with respect to the pivoting direction. The locking lever is preferably used in the case of multipole elongated electrical plug connections.
Abstract: The expandable jack has first and second members attached by a pivotal connection. The members can be expanded about the pivotal connection to form a receptacle for receiving a plug and, when not in use, the members can be collapsed about the pivotal connection to fit into storage spaces of reduced size. The jack is of particular use in application interface cards for laptop, notebook and palmtop computers. In such cards, the jack is mounted on a platform which is movable between an exposed position, external of the card, and a retracted storage position within the body of the card. A plug can be inserted into the expandable jack while avoiding interference with obstructions, such as a cable extending from an adjacent card in the computer.
