Description

本発明は、携帯用電子機器に使用される電池を充電するものに関するものである。   The present invention relates to a battery for charging a battery used in a portable electronic device.

近年、電子機器の安全性が高まる中、デジタルスチルカメラなどにおける携帯用電子機器の充電式機器の充電装置において、充電器本体と充電池を内蔵した機器との接続に関しては電気的接点を有して接続し充電する方式が一般的である。   In recent years, as the safety of electronic devices has increased, charging devices for rechargeable devices for portable electronic devices such as digital still cameras have electrical contacts for connection between the charger body and devices with built-in rechargeable batteries. The method of connecting and charging is generally used.

しかしながら、電気的接点を有する接続においては、外的要因によるショートによる破損、発熱および塵埃などによる接触不良など品質不良が発生する可能性がある。   However, a connection having an electrical contact may cause quality defects such as damage due to a short circuit due to external factors, contact failure due to heat generation, dust, and the like.

上記を実現するため、トランスの電磁誘導の原理を応用し１次側と２次側を独立させて充電器を構成した無接点化を実現していた（例えば、特許文献１および２参照）。
特開２００５−１３７１７３号公報 特開２００２−２６２４６８号公報 In order to realize the above, the principle of electromagnetic induction of a transformer is applied to realize a contactless configuration in which a charger is configured by making the primary side and the secondary side independent (see, for example, Patent Documents 1 and 2).

しかしながら前記従来例の１次、２次の分離方式ではコアの同一軸上にコイルが巻回されて無いか、コアを使用していないため、１次、２次間の結合度が低く変換効率が悪いため、低コスト、高効率の充電システムの実現は困難であった。   However, in the conventional primary and secondary separation methods, the coil is not wound on the same axis of the core or the core is not used, so the degree of coupling between the primary and secondary is low and the conversion efficiency is low. Therefore, it has been difficult to realize a low-cost, high-efficiency charging system.

本発明は、上記課題を解決し、低コストかつ高効率の充電を実現するものである。   This invention solves the said subject and implement | achieves low-cost and highly efficient charge.

上記従来の課題を解決するために、本発明の充電器は、スイッチング電源用のトランスの１次側と２次側を分離し１次側では、１次側コアの軸部を中心に１次コイルを巻回し１次側ケース覆い、２次側では、２次側コア軸部を中心に２次コイルを巻回し２次側ケースで覆い、１次側と２次側の結合時では１次側コアの軸部と２次側コア軸部が磁気結合したことを特徴とする充電器。   In order to solve the above-described conventional problems, the charger of the present invention separates the primary side and the secondary side of the transformer for the switching power supply, and on the primary side, the primary side is centered on the shaft portion of the primary side core. The coil is wound to cover the primary side case, and on the secondary side, the secondary coil is wound around the secondary side core shaft portion and covered with the secondary side case, and the primary side and the secondary side are primary when coupled. A charger characterized in that the shaft portion of the side core and the secondary core shaft portion are magnetically coupled.

本発明よると、１次コイルと、２次コイルを近接させ、コアの同一軸線上に配置させることで、１次コイル、２次コイル間の結合度を飛躍的に増加させることが可能なため、充電器を高効率化することが可能となる。   According to the present invention, it is possible to dramatically increase the degree of coupling between the primary coil and the secondary coil by placing the primary coil and the secondary coil close to each other and arranging them on the same axis of the core. It becomes possible to increase the efficiency of the charger.

以下本発明を実施するための最良の形態について、図面を参照しながら説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

（実施の形態１）
図１は本発明の実施の形態１におけるの構成図である。図１において１次側は、１次側コア４の１次側コア軸部４ａを中心に１次コイル７が巻回されており、１次側ケース２によって覆われている。また、２次側は、２次側コア３の２次側コア軸部３ａを中心に２次コイル６が巻回されており、２次側ケース１によって覆われている。 (Embodiment 1)
FIG. 1 is a configuration diagram according to Embodiment 1 of the present invention. In FIG. 1, a primary coil 7 is wound around the primary side core shaft portion 4 a of the primary side core 4 on the primary side, and is covered with the primary side case 2. A secondary coil 6 is wound around the secondary side core shaft 3 a of the secondary side core 3 on the secondary side, and is covered with the secondary case 1.

この様な構成において、２次側と１次側が結合した場合、１次側コア軸部４ａと２次側コア軸部３ａは磁気的に同一軸となり１次コイル７と２次コイル６は同一軸線上に配置され結合度を上げることが出来る為、低コスト、高効率の充電制御の出来る無接点充電器を提供することができる。   In such a configuration, when the secondary side and the primary side are coupled, the primary side core shaft portion 4a and the secondary side core shaft portion 3a are magnetically on the same axis, and the primary coil 7 and the secondary coil 6 are the same. Since it is arranged on the axis and the degree of coupling can be increased, it is possible to provide a non-contact charger capable of charge control with low cost and high efficiency.

（実施の形態２）
図２は本発明の実施の形態２における構成図である。図２においては１次側は、１次側コア４の内部に１次コイル７が巻回されており、１次側ケース２によって覆われている。また、２次側は、２次側コア３の２次側コア軸部３ａを中心に２次コイル６が巻回されており、２次側ケース１によって覆われている。 (Embodiment 2)
FIG. 2 is a configuration diagram according to the second embodiment of the present invention. In FIG. 2, the primary side is covered with a primary side case 2, in which a primary coil 7 is wound inside a primary side core 4. A secondary coil 6 is wound around the secondary side core shaft 3 a of the secondary side core 3 on the secondary side, and is covered with the secondary case 1.

この様な構成において、２次側と１次側が結合した場合、１次コイル７は２次側コア軸部３ａを中心に巻回されたものと同等になり、１次コイル７と２次コイル６は２次側コア軸部３ａ上で磁気結合し結合度を上げることが出来る為、低コスト、高効率の充電制御の出来る無接点充電器を提供することができる。   In such a configuration, when the secondary side and the primary side are coupled, the primary coil 7 is equivalent to that wound around the secondary core shaft portion 3a, and the primary coil 7 and the secondary coil 6 can be magnetically coupled on the secondary core shaft portion 3a to increase the degree of coupling. Therefore, it is possible to provide a contactless charger capable of charge control with low cost and high efficiency.

本発明にかかる充電器は、携帯用電子機器に使用される電池を充電するものであり、高い効率性を実現に有用である。   The charger according to the present invention charges a battery used in a portable electronic device, and is useful for realizing high efficiency.
