PROBLEM TO BE SOLVED: To provide a power source connecting equipment such as an outlet, etc., preventing heat generation and ignition caused even when dust piles on it. SOLUTION: When an AC adapter 14 is put in a second area 22, of a cap 21 of an exposed square triple outlet, in an inclined state forming a clearance gap in the upper part, then comparatively massive dust 19 piles up on it as time goes by. A second movable member 32 is mounted to the cap 21 so as to move back and forth, and it blocks the upper part of the clearance gap. Thereby, the dust is prevented from piling up on the place where a pair of plug blades 14A of the AC adapter 14 exists. This eliminates the risk of electrification of the dust and sparkling between the pair of plug blades 14A or between second plug blade sockets.
