20150249305 | POWER SUPPLY CONNECTOR AND METHOD FOR UNLOCKING POWER SUPPLY CONNECTOR - According to the present invention, the pin, which is provided on the link member that links the lock lever and the electromagnetic solenoid, can be removed from both sides of the power supply connector. Thus, the pin can be removed from the side that allows workspace, regardless of the side on which the openable lid of the power reception connector is positioned. Thus, even when the electromagnetic solenoid malfunctions, the pin can be extracted with certainty, and the lock can be released. Thus, the power supply connector can be pulled out from the power reception connector. Further, because a cover is provided on the grasping member, the pin extraction workability is also excellent. | 09-03-2015 |
