PURPOSE:To free a user's mind from a feeding of uneasiness about an electric shock even when electricity charged by a movable plug by providing a movable cover which blocks a fixed socket while interlocking with switching to a projection/service condition of a movable plug. CONSTITUTION:A case 10 wherein a fixed socket and a movable plug 9 are incorporated is installed on the bottom of a body case 1. A socket pin 14 is inserted into a plate 17 and a substrate 18 and passed through them. The plug 9 is made up of a pair of plug blades 21 and a base of blades 22, and the base is moved smoothly and freely right and left. A plug cover 24 keeps a blade retreat port 23 in a normally closed position by a spring 25. When the plug 9 is not used, it is prevented from projection by holding an operation button 28 at the right side of a positioning projection 33 located on a cover plate 26 with a coiled spring 32 between the blade base 22 and the operation button 28. Disengagement can be made by pushing the button 28 in. A movable terminal block 34 is attached to the plate 17 and the substrate 18, a pair of terminals 39 are installed on the under face of the terminal block 34, and connected to an electric circuit 5 through two circuits 10 on the substrate 18. |
