The insert socket is a housing that is placed over the existing socket and fastened thereto. The insert socket consists of a lower threaded segment that is threaded into the existing socket. There is an upper threaded segment that will receive the light bulb. When the light bulb is threaded into the upper segment it will encounter a plate there below and will cause the upper threaded segment to slide upwardly together with a bracket to which it is attached. There is a sliding hot prong and a sliding neutral prong which will make contact when the bracket moves upwardly and will convey electric current to the light bulb.

  • Patent number: 7637755
    Abstract: In a vehicle audio apparatus, the detection switch is turned off when the lock claw is released from the lock-claw holder to open the front panel. The bi-directional switches are thereby turned off, disconnecting the data lines SD+and SD? between the USB interface unit of the main unit and the USB socket of the front panel. Thereafter, the front panel is opened, releasing the connector (22) from the connector 13 and ultimately disconnecting the power-supply lines (VBUS and GND). Hence, the vehicle audio apparatus is prevented from being abruptly disconnected from the power supply. This prevents the data stored in the USB memory from being destroyed.

Thus, users can lock or unlock the optical module without other additional operation while transporting the scanner. It avoids possible damages to the optical module.

  • Patent number: 6817882
    Abstract: The apparatus (2) for vibrationproof locking of a plug (3) in its plugged-in position inside a unit, in particular inside a clutch actuator (1), encompasses a housing (4) that has a housing top shell (16) and a housing bottom shell (6), by means of at least one locking element (30) that engages the plug (3). The locking element (30) has a blocking section (52), which is kept in a blocking position by the plug (3) when this plug is not completely plugged in—thus preventing the housing shells (6) from being joined—and which can be brought into a position that permits the housing shells (6) to be joined only when the plug (3) is completely plugged in.

  • Patent number: 6817873
    Abstract: A blocking outlet and corresponding locking plug provide a completely enclosed safety electrical connection system for supplying electrical power from a wall fixture. The blocking outlet installs in a conventional wall-mounted electrical box, providing access to building electrical wiring. The outlet has receptacles that retain spring-loaded covers, which have a closed position generally flush with the front side of the face plate. The springs provide sufficient tension to the covers to block small children from inserting fingers or foreign objects into a receptacle, preventing inadvertent exposure to hazardous voltage. Yet adults can easily insert a corresponding locking plug directly into a receptacle without cover removal. Regardless, the interior of a receptacle has no exposed contacts. Small access apertures in the interior of an outlet receptacle contain recessed contacts.

  • Patent number: 6634898
    Abstract: A telecommunications server comprises a switch/larch mechanism for use in online removal or insertion of a peripheral card, such as a PCI card. A bulkhead is adapted for mating engagement with a bulkhead mounting bracket of the peripheral card when the peripheral card is installed in the switch/latch mechanism. A doorbell switch having a vertical range of motion is manually depressed to signal the server and commence an orderly shutdown of the peripheral card in advance of online replacement of the peripheral card. A panel switch provides a mechanical lock retaining the peripheral card in place, and also function as a backup power interrupt device to protect the peripheral card in the event that depression of the doorbell button does not result in an orderly shutdown of the peripheral card.

  • Patent number: 6523960
    Abstract: The invention provides a light source device of an easy maintenance, and a projector using the light source device. The light source device includes a light source lamp, a reflector, a lamp housing for covering substantially entirely almost the outer surface except for an opening plane of the reflector and a front glass for covering the opening plane of the reflector. The light source device is formed so as to be integrally exchangeable as a unit in the projector. Since the lamp housing covers almost the whole surface of the reflector, even if the light source lamp and the reflector burst, fragments thereof do not scatter to the inside of the projector, there is no need to remove the outer casing to clean the inside of the device, and maintenance of the projector can be facilitated.

  • Patent number: 6439917
    Abstract: An electronic unit having an electric connecting part connectable with a plug is accommodated in a housing of an electronic equipment so that the electronic unit can be attached to and detached from the housing. An engaging arm is rotatably mounted on one face of the electronic unit on which the electric connecting part is provided. When a plug is connected to the electric connecting part of the electronic unit, one end of the engaging arm is engaged with the engaging portion of the housing, whereby the electronic unit can be prevented from being pulled out from the housing. When the plug is detached from the electric connecting part of the electronic unit, the engaging portion of the engaging arm can be disengaged from the housing by the rotation of the engaging arm. Therefore, if the plug is detached from the electric connecting part of the electronic unit, the electronic unit can be pulled out from the housing.
