<p><P>PROBLEM TO BE SOLVED: To reduce the thickness, size and weight of a magnetic coupler without causing abnormal overheat of a core or a coil nor degradation of power transmission efficiency. <P>SOLUTION: In this magnetic coupler where a primary unit and a secondary unit are arranged oppositely to each other through a nonmagnetic body and can be magnetically coupled to each other, both the units 100, 200 include coils 103, 203 each formed of a flat braided wire, respectively, and further include cores 101, 201 relatively movable for winding coils 103, 203 therearound, respectively; and so-called dust core and dust material are used as material of the cores 101, 201. The primary unit is fixed, and a reciprocating conductor formed of a pair of conductors is arranged in a part of the coil constituting the primary unit; and the secondary unit can be moved along the longitudinal direction of the reciprocating conductor. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
