  • Patent number: 9614307
    Abstract: A connector in an electronic device includes a case, a supporting element, and an elastic element. The case defines a through hole and a plurality of latching portions protruding from an inner surface of the case surrounding the through hole. The latching portions include an engaging surface and a guiding surface adjacent to the engaging surface. The supporting element is partially received in the through hole. The supporting element includes terminal recesses and resisting pieces engaging with the engaging surface. The elastic element is partially received in the supporting element and supplied a resilient force. When the supporting element is moved away from the case, the resisting piece is separated from the engaging surface to make contact with the guiding surface under the resilient force. If reassembly of the connector contacts is not in the predetermined order the electronic device will be locked down.

  • Patent number: 9385522
    Abstract: A low fault current isolation arrangement senses a loss of voltage and automatically isolates and de-energizes a down live primary wire if overcurrent protection devices have not cleared the high impedance fault in an electric power distribution network. Incorporating an operator selectable time delay response, the low fault current isolation arrangement permits overcurrent protection devices to attempt to detect and shut down the affected conductor, and then isolates and shuts down the low current fault if the overcurrent devices are not successful. The isolation arrangement continuously monitors AC voltage as remotely provided by smart meters even after a fault location is de-energized, and serves as a back up, and not as a replacement, for existing overcurrent protection schemes. A host computer operates in conjunction with plural smart meters each coupled to an associated customer distribution transformer in conjunction with the fault isolator to detect and shut down high impedance faults.

  • Patent number: 7775814
    Abstract: Shipment and storage of systems poses integrity and economical issues. Such systems may require substantial packaging to protect components of the system during shipment and storage. Some components, such as a battery, may need to be separated from the system during shipment to prevent either actual or perceived damage by the user of the system. A battery directly connected to a system may discharge so as to be incapable of providing sufficient power to the system. Users may erroneously believe that the system is defective and place unnecessary service calls. Such service calls increase costs and affect future business activity. Configuring the terminals of high current connectors coupled to the battery and the system allow for an isolator to be inserted between the high current connectors to prevent conduction while allowing the connectors to mate which results in feasibly shipping the battery in tact within the system.
