Abstract

An electromagnetic induction-type connector for feeding electric power or a signal by a mutual induction action, includes a first connector, including a first core member which has a primary-side core and a primary-side coil, a second connector, including a second core member which has a secondary-side core and a secondary-side coil, the second core member producing an induction electromotive force in accordance with the first core member, and at least one of a first metal case and a second metal case. The first metal case is directly contacted with the first core member, and includes a receiving portion receiving a circuit board to which the primary-side coil is electrically connected and includes a contact portion contacting with a connector mounting portion. The second metal case is directly contacted with the second core member, and includes a receiving portion receiving a circuit board to which the secondly-side coil is electrically connected and includes a contact portion contacting with a connector mounting portion. A heat produced in the first core member and the second core member by the mutual induction action is radiated to the connector mounting portion through the contact portion.

Claims

1. An electromagnetic induction-type connector for feeding electric power or a signal by a mutual induction action, comprising:

a first connector, including a first core member which has a primary-side core and a primary-side coil;

a second connector, including a second core member which has a secondary-side core and a secondary-side coil, the second core member producing an induction electromotive force in accordance with the first core member; and

at least one of a first metal case and a second metal case,

wherein the first metal case is directly contacted with the first core member, and includes a receiving portion receiving a circuit board to which the primary-side coil is electrically connected and includes a contact portion contacting with a connector mounting portion;

wherein the second metal case is directly contacted with the second core member, and includes a receiving portion receiving a circuit board to which the secondly-side coil is electrically connected and includes a contact portion contacting with a connector mounting portion; and

wherein a heat produced in the first core member and the second core member by the mutual induction action is radiated to the connector mounting portion through the contact portion.

2. The electromagnetic induction-type connector as set forth in claim 1, wherein a thermal conductive filler is filled in a gap between the primary-side core and the primary-side coil.

3. The electromagnetic induction-type connector as set forth in claim 1, wherein a thermal conductive filler is filled in a gap between the secondary-side core and the secondary-side coil.

4. The electromagnetic induction-type connector as set forth in claim 1, wherein the first metal case has a thermal conductive portion directly contacting the primary-side coil.

5. The electromagnetic induction-type connector as set forth in claim 1, wherein the second metal case has a thermal conductive portion directly contacting the secondary-side coil.

6. The electromagnetic induction-type connector as set forth in claim 1, wherein a waterproof and heat radiation sheet is provided on the contact portion so that the sheet is held between the contact portion and the connector mounting portion.

7. The electromagnetic induction-type connector as set forth in claim 1, wherein the contact portion is fixed on the connector mounting portion by a connector fixing member.

8. The electromagnetic induction-type connector as set forth in claim 1, wherein a electronic part mounted on the circuit board is contacted with the first metal case.

9. The electromagnetic induction-type connector as set forth in claim 1, wherein a electronic part mounted on the circuit board is contacted with the second metal case.
