  • Patent number: 5639268
    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.

  • Patent number: 5639270
    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.

  • Patent number: 5639271
    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.

  • Patent number: 5634804
    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.

  • Patent number: 5634802
    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.
