Patent number: 10020681Abstract: A coupling electrode of a communication coupler is installed at an opening of a substrate and is, viewed from an orthogonal direction orthogonal to a coil axial direction of a power transmission coil, positioned to the substrate side in the coil axial direction than a coil end portion of the power transmission coil opposite side to the substrate. For example, an end portion of the coupling electrode on a communication side in the coil axial direction positions, viewed from the orthogonal direction, at the same position as a surface of the substrate opposite to the power transmission coil, in the coil axial direction.Type: GrantFiled: August 18, 2016Date of Patent: July 10, 2018Assignee: YAZAKI CORPORATIONInventors: Tatsuo Toba, Kyoko Furuhashi, Kenji Matsushita, Yuta Nakagawa, Shingo Tanaka, Yoichi Ido, Noritaka Taguchi

Patent number: 9893566Abstract: Provided is a power supply system which can reduce a decrease in transmission efficiency caused by displacement of a power supply side coil with respect to a power reception side coil and which can supply power from a power supply unit to a power reception unit with high efficiency. A power supply part includes a power supply side helical coil (33) to which power is supplied. A power reception part includes a power reception side helical coil (51) which electromagnetically-resonates with the power supply side helical coil (33) and receives power from the power supply side helical coil (33). Impedances of the power supply part and the power reception part are matched at position where center axes (Z1, Z2) of the power supply side helical coil (33) and the power reception side helical coil (51) are displaced with respect to each other.Type: GrantFiled: September 22, 2014Date of Patent: February 13, 2018Assignee: Yazaki CorporationInventors: Masamitsu Ookawa, Shingo Tanaka, Noritaka Taguchi
