  • Patent number: 8736226
    Abstract: A charging cable for an electric vehicle includes a power plug adapted to be detachably connected to a power socket of a commercial power source; a temperature detecting unit for detecting a temperature of the power plug; a cable connector adapted to be detachably connected to an electric vehicle for supplying a charging current to a battery of the electric vehicle; and a switching unit for opening and closing a current path between the power plug and the cable connector. The charging cable further includes a leakage detecting unit for detecting an electric leakage based on a current flowing through the current path; and a power cutoff unit for opening the switching unit when the detected temperature of the temperature detection means exceeds a threshold value or when the leakage detection means detects the electric leakage.

  • Patent number: 8737026
    Abstract: An electric vehicle charging cord set includes a housing containing an interrupting device therein and a first cord provided at one end with a plug connectable to an outlet installed on a wall surface of a building and at the other end connected to one of the terminal units of the interrupting device. An electric vehicle charging cord set further includes a second cord provided at one end with a connector connectable to an inlet of an electric vehicle and at the other end connected to the other of the terminal units of the interrupting device. The housing includes a storage unit for extendibly storing the second cord, a stand for placing the housing on a ground surface and a transportation handle. The storage unit includes a drum rotatably attached to the housing. The second cord is wound on the outer circumferential surface of the drum.

  • Patent number: 5331302
    Abstract: A miniature transfer relay has a base mounting a contact assembly and an electromagnet. The contact assembly includes a normally-open (NO) fixed contact, a normally-closed (NC) fixed contact, a common conductor, and a movable spring extending from the common conductor and carrying first and second movable contacts engageable respectively with the NO and NC contacts. The electromagnet block includes an armature which is movable between set and reset positions and is connected to the movable spring for making and breaking the NO and NC contacts simultaneously in response to the armature movement. The NO fixed contact and the common conductor are molded in an upper surface of the base, while the NC fixed contacts has a portion molded in the base.
