Electric vehicle charging cord set
First Claim
1. An electric vehicle charging cord set, comprising:
- a housing containing an interrupting device therein, the interrupting device being provided with a pair of terminal units and adapted to disconnect the terminal units from each other at the occurrence of electric leakage;
a first cord provided at one end with a plug connectable to an outlet installed on a wall surface of a building, the first cord being connected at the other end to one of the terminal units of the interrupting device; and
a second cord provided at one end with a connector connectable to an inlet of an electric vehicle, the second cord being connected at the other end to the other of the terminal units of the interrupting device,wherein the housing includes a storage unit for extendibly storing the second cord, a stand for stably placing the housing on a ground surface and a transportation handle, and wherein the storage unit includes a drum rotatably attached to the housing for rotation about a rotational axis and provided with an outer circumferential surface, the second cord being wound on the outer circumferential surface of the drum along a plane perpendicular to the rotational axis,wherein the interrupting device includes;
a switching mechanism configured to perform switching operation between the terminal units;
a control unit configured to control the switching mechanism; and
a power supply unit configured to supply a power to the control unit,wherein the housing is provided with a holder portion for holding the connector in place,wherein the holder portion includes a box-shaped holding part protruding from the housing, the holding part having flat rectangular surfaces and an opening on an upper surface of the holding part, andwherein the holder portion is configured such that the connector is held within the holder portion in a state that a tip end portion of the connector is inserted into the holder portion through the opening.

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.

9. An electric vehicle charging cord set, comprising:
-
a plug removably connectable to an outlet supplied with a commercial electric power; a plurality of vehicle-couplable connectors each removably connectable to a connector of an electric vehicle to feed a charging current therethrough to a battery of the electric vehicle; and a selector unit to which the vehicle-couplable connectors and the plug are connected through a charging cable, the selector unit being configured to select one of the vehicle-couplable connectors and to allow the charging current to be fed to the selected vehicle-couplable connector, wherein the selector unit includes; at least one changeover contact switch each being configured to connect the plug to one of at least three contact points including one dummy contact point connected to none of the vehicle-couplable connectors; an electric leakage detector unit configured to detect an electric current leakage from the charging cable when the charging current is fed to the selected vehicle-couplable connector; and a control unit configured to control each changeover contact switch to connect the plug to the dummy contact point when the electric current leakage is detected by the electric leakage detector unit. - View Dependent Claims (10)
