  • Publication number: 20120094549
    Abstract: An objective is to produce the plug-in-connector for DC-wiring with safety by preventing degradation of contact points by shortening of period when arc is caused due to detaching and attaching the plug. An electrical outlet comprises an inversion-spring electrically connected to the plug's blade inserted from the insertion-hole. Both the ends of the inversion-spring are fixed to the inversion-spring's body, whereby the inversion-spring's intermediate-portion is moved between the contact position of making an elastically contact with the blade and the non-contact position of making a space having a predetermined distance or more for cutting the arc. The blade pushes the intermediate-portion to move it to the non-contact position by twisting the plug having a contact condition between the intermediate-portion and the blade. The intermediate-portion is inverted to have an elastic contact to the blade by pushing the push button to move the intermediate-portion, with non-contact position, by the driving member.

    Abstract: The power supply apparatus includes a first power device, a second power unit, and controlling means. Each of the first power device and the second power unit supplies DC power to a DC supply line. The first power device makes constant voltage control. The second power unit includes a second power device configured to make inclination control of monotonically decreasing its output voltage with an increase of its output current, and of monotonically increasing its output voltage with a decrease of its output current. Upon acknowledging that a measurement (a magnitude of a current flowing through the DC supply line) exceeds an optimal current magnitude (a magnitude of a current supplied to the DC supply line from the first power device operating at maximum conversion efficiency), the controlling means outputs an instruction such that a magnitude of a current supplied to the DC supply line from the second power unit is identical to a difference between the measurement and the optimal current magnitude.
