Patent number: 5850135Abstract: To facilitate the charging of an electric automotive vehicle, a primary coil 31 connected with a charging power source is so provided as to project from a wall surface W of a parking space. An electric automotive vehicle E is advanced toward the wall surface W and parked in a position where the primary coil 31 is accommodated in a receptacle 11 provided below a front bumper B of the vehicle E. Then, a pressure switch 40 provided in a shock absorbing material 39 operates to detect the presence of the vehicle E, and the primary coil 31 is excited. A secondary coil 14 is provided above the receptacle 11. A voltage is generated in the secondary coil 14 by action of electromagnetic induction, thereby charging a battery 19.Type: GrantFiled: January 30, 1997Date of Patent: December 15, 1998Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Heiji Kuki, Sho Miyazaki, Tsutomu Tanaka, Kunihiko Watanabe, Shuichi Kanagawa, Tomohiro Keishi, Hiroshige Deguchi, Shuji Arisaka

Patent number: 5807129Abstract: To securely lock connectors for charging, a charging connectors 1 is engaged with a vehicle-side connector 25, lock balls 9 are engaged with an engaging groove 28 and a locking member 10 is engaged with the lock balls 9. As a result, the connectors 1 and 25 are locked. Since the connectors 1 and 25 are locked by a ball lock mechanism taking advantage of the engagement of the lock balls 9, the connectors can be more securely locked even if the connectors and wires are heavy as compared to a prior art locking mechanism adopting an elastically deformable resin lance or engaging member and, therefore, a better reliability can be ensured.Type: GrantFiled: August 9, 1996Date of Patent: September 15, 1998Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Kazumoto Konda, Sho Miyazaki, Shuichi Kanagawa, Tsutomu Tanaka, Kunihiko Watanabe
