Title
(EN) NON-CONTACT POWER SUPPLY COIL AND BURIED STRUCTURE THEREOF
(FR) BOBINE D'ALIMENTATION ÉLECTRIQUE SANS CONTACT ET STRUCTURE ENFOUIE ASSOCIÉE
(JA) 非接触給電用コイル及びその埋設構造
Abstract
(EN) A non-contact power supply coil (1) comprises a coiled conductor (2) and a magnetic plate (3) formed from ferrite and the like. The magnetic plate is placed adjacent to the coiled conductor so as to be generally orthogonal to an axis line (7) of the coiled conductor (2). An opening (4) is provided in the magnetic plate (3), and the axis line (7) of the coiled conductor (2) is positioned in the vicinity of the center of the opening. The opening and a hollow space (5) of the coiled conductor (2) are continuously integrated so as to form, in the vicinity of the center of the non-contact power supply coil (1), a through-hole (6) extending along the axis line (7).
(FR) Une bobine d'alimentation électrique sans contact (1) comprend un conducteur enroulé (2) et une plaque magnétique (3) formée à partir de ferrite et similaire. La plaque magnétique est placée adjacente au conducteur enroulé de manière à être généralement orthogonale à une ligne d'axe (7) du conducteur enroulé (2). Une ouverture (4) est disposée dans la plaque magnétique (3), et la ligne d'axe (7) du conducteur enroulé (2) est positionnée à proximité du centre de l'ouverture. L'ouverture et un espace creux (5) du conducteur enroulé (2) sont intégrés en continu de manière à former, à proximité du centre de la bobine d'alimentation électrique sans contact (1), un trou traversant (6) s'étendant le long de la ligne d'axe (7).
(JA) 非接触給電用コイル(1)は、コイル状導体(2)と、フェライト等で形成された磁性板(3)とを備える。該磁性板は、コイル状導体(2)の軸線(7)に対し概ね直交するように、該コイル状導体に隣接して配置されている。磁性板(3)には開口(4)が設けられており、コイル状導体(2)の軸線(7)は該開口の中心の近傍に位置決めされている。該開口とコイル状導体(2)の中空空間(5)とは、軸線(7)に沿って延びる貫通孔(6)を非接触給電用コイル(1)の中央近傍に形成するように連続一体化している。
