Connecting device for supplying electric power from an outside power supply to a vehicle
First Claim
1. A connecting device comprising:
- a shaft;
a drum that has a container defined therein, the drum being rotatably disposed on said shaft;
a stator that is fixed to said shaft and is contained inside of said container;
a rotator that is;
i) fixed to said drum, ii) rotatably disposed on said shaft, and iii) contained inside of said container separated by an interval from said stator;
first terminals that are disposed in said stator;
second terminals that are disposed in said rotator and are brought into contact with said first terminals, respectively;
a connecting cord that is wound around said drum, the connecting cord having one end that includes a connecting plug configured to be connected to a vehicle, the cord having another end configured to be electrically connected to said second terminals;
a power supply cord having a power source plug configured to be connected to an outside power supply disposed at one end thereof;
a leakage detector that is;
i) configured to be connected to the other end of said power supply cord and said first terminals, and ii) contained inside of said container;
a controller, that is i) contained inside of said container, and ii) configured to control a drive of said leakage detector;
a first signal terminal that is disposed in said stator and is electrically connected to said controller; and
a second signal terminal that is;
i) disposed in said rotator, ii) brought into contact with said first signal terminal, and iii) electrically connected to said connecting plug;
whereinsaid stator and said rotator are arranged in such a manner that their end surfaces arranged in an axial direction of said shaft face each other,said first terminals and said first signal terminal are disposed in said stator at the end surface facing said rotator, serving as an annular metallic ring annularly extending on said shaft,said second terminals and said second signal terminal are disposed in said rotator at the end surface facing said stator, andsaid first signal terminal is positioned outward of said first terminals whereas said second signal terminal is positioned outward of said second terminals.
