<p>PROBLEM TO BE SOLVED: To provide an attachment plug that can be plugged into an electrical outlet easily even by a frail elderly, woman or children.SOLUTION: In an attachment plug 1, an insertion blade 3, an ultrasonic oscillator 6 and a piezoelectric ceramics 7 are installed in a plug case 2, and connected electrically. The piezoelectric ceramics 7 is abutting against the insertion blade 3, and when the insertion blade 3 is inserted into the receptacle 10 of an electrical outlet 8, power is supplied by a switch 11 and the ultrasonic oscillator 6 is driven to cause high frequency vibration of the piezoelectric ceramics 7, that is propagated to the insertion blade 3.</p> |
