  • Patent number: 4773872
    Abstract: In a high-voltage bushing insert having a moving, piston-operated, female contact assembly electrically coupled to an interior metallic sleeve by means of a louvered contact ring, the improvement comprising a static metallic contact member providing an alternative electrical path from said female contact assembly to said metallic sleeve. The static contact member is generally circular and substantially closed at a first end and is multiply slotted adjacent its second end to provide a series of bulbous, spring fingers thereat. The spring fingers making intimate electrical contact with the interior of the female contact assembly in its static position and for a portion of its travel away from the closed end of the metallic sleeve. An exterior ring at the contact's first end assures good electrical contact with the metallic sleeve.

  • Patent number: 4768966
    Abstract: A lampholder for a screw-in lightbulb has a body supporting two cable terminals for connection to an electrical supply, and a contact carrier mounted on the body and defining a bulb receiving socket, the contact carrier being movable between first and second positions relative to the body in a direction parallel to the insertion direction of a bulb and supporting terminals which connect an inserted bulb to the cable terminals when the carrier is in the first position but are spaced from the cable terminals when the carrier is in the second position. A spring pushes the carrier to the second position. When a bulb is screwed part-way into the carrier socket it bears against a fixed abutment so that the carrier is moved from the second to the first positions as the bulb is screwed fully into the socket.

  • Patent number: 4764132
    Abstract: A connector block assembly for electrically connecting a proximal ring electrode of a bipolar pacemaker lead to the pacemaker. The connection is made in a way that maintains secure electrical contact and that prevents the delicate proximal ring electrode from being damaged or deformed. The pacemaker includes a connector block having a channel therethrough into which the proximal ring electrode is inserted. A C-ring is sandwiched between the ring electrode and an inner wall of the connector block's receiving channel. A setscrew adjustably forces the C-ring against the ring electrode. Mechanical stop means limit the transverse movement of the C-ring, thereby preventing the ring electrode from being deformed, while still maintaining a firm grasp of the ring electrode between the C-ring and the connector block. An alternative embodiment employs a resilient spring to firmly hold the ring electrode in electrical contact with the connector block.

  • Patent number: 4759722
    Abstract: A plug for coaxial cable of the type used for wire broadcasting transmission or multiplex communication system comprising a shielding cap. The shielding cap molded from a conducting material is connected to the cable without stripping the outer insulating material because several sharp-edged sector-shaped projections formed at the end of the shield cap penetrate into the outer insulation of the cable and their tips stick in the shielding net of the cable. A socket or other contact elements of other electrical circuits may or may not have a thread for engaging the assembled plug since the shielding cap itself is made of an elastic material which allows sliding fit instead of thread engagement.

  • Patent number: 4755152
    Abstract: A system for protecting exposed portions of an electric cable mounted in an electrical connector from detrimental components, such as liquids and gases, by inserting a movable sealing material into a cavity in the electrical connector and displacing the movable sealing material during the insertion of the electrical cable into the electrical connector so as to form an effective seal between the outer surface of the electrical cable and the inner surface of the electrical connector to prevent any detrimental components from entering into the electrical connector and attaching a continuous glob of movable sealing material to close an opening in the electrical connector so that, when an electrical cable is mounted in the electrical connector with the bared end portion passing through the glob of movable sealing material, exposed portions of the electrical cable will be protected by the movable sealing material.

  • Patent number: 4753606
    Abstract: A telephone connector block having improved means for temporarily retaining the ends of individual subscriber pairs adjacent the open ends of quick-clip connectors prior to engagement therewith using an installation tool. This is accomplished by a strain relief means which engages an individual conductor as the same is bent to substantially a right angle relative to the axis of the opening in the adjacent quick clip terminal whereby upon bending the end of the conductor and the engagement of a short projection on the strain relief means, the conductor remains in desired position prior to full engagement with the quick-clip terminal.

  • Patent number: 4753609
    Abstract: The present invention is directed to a ganged lamp socket device especially applicable for a bank of LED's. The apparatus includes a housing having a row of sockets with a groove and first pockets on one side of the row and a plurality of second pockets on the other side. A common terminal strip fits in the groove and first pockets, while a plurality of contact members fit in the second pockets. The apparatus is easily assembled using the common strip and plurality of contact members formed in a single conductive sheet. The strip is inserted in the groove and broken from the sheet and then the contact members which are held together by a carrier are inserted in the second pockets. The carrier is broken from the contact members and all the items are pressed into place. The apparatus reduces the number of piece parts normally needed for this type of device and increases system reliability.
