  • Charging apparatus
    Patent number: 8961216
    Abstract: When a power supply plug 40 is inserted into a case 20, a swing pin 43 of the power supply plug 40 pushes a slidable pin 57 in the case 20. Then, when an engaging part 45 of the power supply plug 40 provided at the tip end of the swing pin 43 is engaged with an engaging part 59, the slidable pin 57 is restored to its original position at a mouth, and the periphery of the swing pin 43 abuts against the periphery of the slidable pin 57, and thus the power supply plug 40 and the case 20 are locked. In addition, a locking device 50 having the slidable pin is disposed at the back of the case 20, and a first waterproof wall 30 and a second waterproof wall 34 are provided at positions closer to the mouth than the locking device 50.
