<p>PROBLEM TO BE SOLVED: To obtain an electromagnetic type connector which can supply power with a stable power supply efficiency. SOLUTION: A secondary core 25 has a cylinder 25A and a back wall 25B, the back wall 25B is formed with a shaft insert hole 25C, and a primary core 28 has a circular closure plate 23A a shaft member 28B projected therefrom. The both cores 25 and 28 are set so that, in a connector coupled state, the closure plate 23A is positioned at a side deeper than a front end face 25D of the cylinder 25A, and a tip end of the shaft member 28B is projected as passed through the back wall 25B. As a result, even when the both cores 25 and 28 vary in their length dimensions or in the insertion depths of the cores, there will occur no variations in the junction area of the both cores 25 and 28 magnetically coupled and in the gap dimension between junction faces, whereby power supply can be carried out with a stable efficiency.</p> |
