  • Patent number: 6227888
    Abstract: An interchangeable plug device includes an electrical plug detachably mountable to a casing and movable between a detached and an operative position relative to the casing, and a releasable locking mechanism integral with the electrical plug to maintain the plug in an operative position. The locking mechanism can be released by a user to allow the plug to be moved to the detached position. A preferred form of locking mechanism is a depressible lock bar connected to or integral with an electrical plug body, which is designed to engage a detent in a casing. A preferred form of electrical connection between the plug and any casing comprises a submerged pin and sleeve configuration to protect the user or passerby from electric shock if the plug is detached from its operative position but remains a source of live current. A variety of interchangeable electrical plugs can preferably be fitted to the same casing.

  • Patent number: 6155857
    Abstract: A connector for making electrical connection between electrical terminals held in each of a female electrical terminal member and a male electrical terminal member of the connector by mechanically connecting both the female electrical terminal member and the male electrical terminal member. Both of the female electrical terminal member and the male electrical terminal member of the connector are attached to solid structures directly, instead of being attached to tip portions of flexible electric cables extended from outside of the solid structures. The solid structures are parts such as auto-parts or a partial assembly composed of a plurality of the parts or a body such as a body of an automobile which are to be assembled together and which have a larger size than the size of the connector.

  • Patent number: 6022225
    Abstract: An electrical assembly and actuating mechanism for use therewith in which conductor pairs of two circuit members (e.g., printed circuit board and electronic module or semiconductor chip) are effectively electrically coupled. A rigid plate is fixedly positioned relative to a first of the circuit members (e.g., using upstanding pins), a pressure plate is movably oriented relative to the rigid member, and an actuator (e.g., screw) moves within the rigid member to cause the pressure plate to engage the second circuit. Such engagement in turn causes the conductors of the second circuit member to forcibly engage the first circuit member's conductors. Solder balls and dendritic members can also be used for providing enhanced coupling without harm to either structures. The resulting assembly affords a low profile when in final position, as highly desired in the design of microelectronic packaging structures which the present invention is particularly related to.

  • Patent number: 6010369
    Abstract: Male and female connectors of an extremely small size, while having a number of connection terminals, are provided. The male connector consists of a cylindrical cable-supporting member, a cylindrical conductive-wire guide member, and a core member for coupling the two with each other. The conductive-wire guide member has partitions and holding sections. The conductive wire of the cable passing through the cable-supporting member is folded on the holding section from outside to inside so that the exposed portion of the conductive wire forms a connection terminal of the male connector. The female connector consists of a casing having an insertion hole to be inserted by the male connector, a locking member for locking the male connector, projected from the end of the casing, and female side connection terminals, each to be fitted to a terminal retaining section of the casing so that the leading end thereof is exposed in the insertion hole.

  • Patent number: 5980268
    Abstract: A unique dual beam contact (30) for coupling elements on opposite sides of a dividing element (68) preferably comprises a single piece of metal or other conductive material to provide a contact portion on either side of the dividing element (14). Each beam of the dual beam contact can be specifically shaped or formed to provide the preferred contact pressure depending upon the application the dual beam contact. The dual beam contact includes an attachment member (34, 35) to provide easy attachment to an element of the device. Alternatively, the elbow portion (38) between the two beams could be used to attach the dual beam contact to the dividing element. The dual beam contact of the present invention reduces cost, inventory requirements, and complexity in manufacturing.

  • Patent number: 5971793
    Abstract: A connector for high density multi-conductor ribbon cable. The connector has a base member, a cover member and a retainer interposed therebetween. The cover member and the retainer collectively define a ribbon cable receiving area and the mating surfaces on the cover member and the retainer have indentations that urge the conductors of the ribbon cable so as to center the conductors in a conductor space defined by the indentations. A plurality of contacts are positioned in the base and an insulation displacement ends of the contacts extend through openings in the retainer into the conductors that are centered in the conductor receiving space defined by the indentations. The base member exerts force against the contacts so that compression of the cover and the base results in the conductors simultaneously being centered in the conductor receiving space and the contacts being urged into the conductors.
