SMALL-SIZED ELECTRICAL EQUIPMENT

摘要

PURPOSE:To prevent a heat generation accident misconceiving a foreign matter disposed while being adjoined to a power supply body as an equipment body by mutually constituting the power supply body supplying power and the equipment body with load detachably. CONSTITUTION:A primary coil 14 is arranged at an internal position magnetically separated from a main body case 22 during a time when an equipment body 20 is detached from a power supply body 12. Consequently, magnetic flux density by a magnetic field 107 output from the primary coil 14 is maintained at a sufficiently small value at the peripheral position of the main body case 22 for example, no eddy current is generated even when a foreign matter such as a metallic piece is placed on the main body case 22. Accordingly, a heat generation accident misconceiving the foreign matter disposed while being adjoined to the power supply body 12 as the equipment body 20 can be prevented.
