Description

本発明は、複数巻き接点を有するワイヤ端子構造に関する。   The present invention relates to a wire terminal structure having a plurality of winding contacts.

従来、充電機器（例えば、コードレス子機の充電台等）の端子構造は、単一接点の板バネ端子又はワイヤ端子構造が一般的である（例えば、特許文献１）。   Conventionally, a terminal structure of a charging device (for example, a charging stand of a cordless slave unit) is generally a single contact leaf spring terminal or a wire terminal structure (for example, Patent Document 1).

しかしながら、特許文献１に記載された端子構造は、端子が単一接点の為、充電される相手側の端子との接触面積が小さく、端子の充電部と同じサイズの小さい異物が挟んだ場合、充電不良が発生してしまうという問題がある。   However, since the terminal structure described in Patent Document 1 is a single contact, the contact area with the other terminal to be charged is small, and when a small foreign object having the same size as the charging part of the terminal is sandwiched, There is a problem that charging failure occurs.

以下に、充電機器を例に、図面を参照しながら、本発明の実施の一形態について説明する。ただし、以下の説明は、あくまでも本発明の例示にすぎず、以下の記載によって発明の技術的範囲が限定されるものではない。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings by taking a charging device as an example. However, the following description is merely an example of the present invention, and the technical scope of the invention is not limited by the following description.

図１は、本発明の実施の一形態に係る充電機器１の外観図である。充電機器１の筐体は上ケース３と下ケース４から構成される。充電端子２は充電機器１の内部から外部へ突出している構造である。   FIG. 1 is an external view of a charging device 1 according to an embodiment of the present invention. The casing of the charging device 1 includes an upper case 3 and a lower case 4. The charging terminal 2 has a structure protruding from the inside of the charging device 1 to the outside.

図２(ａ)は、本発明の実施の一形態に係る充電機器１の構成を示す分解図である。図示するように充電機器１は、充電端子２と、上ケース３と、下ケース４と、端子ホルダ５と、回路基板６と、から構成される。図２(ｂ)は、複数巻き接点を有するワイヤ端子、充電端子２の拡大図である。   Fig.2 (a) is an exploded view which shows the structure of the charging device 1 which concerns on one Embodiment of this invention. As illustrated, the charging device 1 includes a charging terminal 2, an upper case 3, a lower case 4, a terminal holder 5, and a circuit board 6. FIG. 2B is an enlarged view of the charging terminal 2 and the wire terminal having a plurality of winding contacts.

充電機器１は、充電される機器(例えばコードレス子機)に搭載される二次電池を充電する機器である。   The charging device 1 is a device that charges a secondary battery mounted on a device to be charged (for example, a cordless child device).

充電端子２は、複数巻き接点を有するワイヤ端子である。充電端子２は充電端子接点２０と充電端子位置決め孔２１と充電端子挿入部２２が設けられている。   The charging terminal 2 is a wire terminal having a plurality of winding contacts. The charging terminal 2 is provided with a charging terminal contact 20, a charging terminal positioning hole 21, and a charging terminal insertion portion 22.

上ケース３と下ケース４は、充電機器１を構成する筐体である。上ケース３は充電端子孔３０が設けられている。   The upper case 3 and the lower case 4 are housings that constitute the charging device 1. The upper case 3 is provided with a charging terminal hole 30.

端子ホルダ５は、樹脂成形品である。端子ホルダ５は位置決め軸５０と嵌合爪５１が設けられている。   The terminal holder 5 is a resin molded product. The terminal holder 5 is provided with a positioning shaft 50 and a fitting claw 51.

回路基板６は、電力を供給する回路が搭載され、嵌合孔６０と貫通孔６１が設けられている。   A circuit for supplying power is mounted on the circuit board 6, and a fitting hole 60 and a through hole 61 are provided.

充電端子２の中央部に設けられている円状の充電端子位置決め孔２１を端子ホルダ５の左右対称に設けられている十字位置決め軸５０に合わせ、端子ホルダ５の左右に充電端子２を１本ずつ装着する。   The circular charging terminal positioning hole 21 provided at the center of the charging terminal 2 is aligned with the cross positioning shaft 50 provided symmetrically with respect to the terminal holder 5, and one charging terminal 2 is provided on the left and right sides of the terminal holder 5. Wear one by one.

嵌合爪５１は、それぞれ対向する位置に設けられた嵌合孔６０と嵌合し、端子ホルダ５は回路基板６の中央部付近に固定する。尚、本実施例において嵌合爪５１と嵌合孔６０は上下２箇所ずつ設けているが、位置と数は問わない。   The fitting claws 51 are fitted into fitting holes 60 provided at positions facing each other, and the terminal holder 5 is fixed near the center of the circuit board 6. In the present embodiment, the fitting claw 51 and the fitting hole 60 are provided at two places on the upper and lower sides, but the position and number are not limited.

充電端子挿入部２２は、それぞれ対向する位置に設けられた貫通孔６１に挿入し、半田付けすることにより、充電端子２は回路基板６に搭載されている電力を供給する回路と接続される。   The charging terminal insertion portion 22 is inserted into a through-hole 61 provided at an opposing position and soldered, whereby the charging terminal 2 is connected to a circuit for supplying power mounted on the circuit board 6.

回路基板６は、充電端子２と端子ホルダ５を装着した状態で上ケース３の所定位置に装着し、充電端子接点２０は充電端子孔３０より充電機器１の内部から外部へ突出させる。充電端子接点２０は外部へ突出している為、充電される機器の端子と接触可能となる。充電端子接点２０は、充電される機器の端子と接触し、充電電流を充電される機器に伝達する。   The circuit board 6 is mounted at a predetermined position of the upper case 3 with the charging terminal 2 and the terminal holder 5 mounted, and the charging terminal contact 20 protrudes from the inside of the charging device 1 to the outside through the charging terminal hole 30. Since the charging terminal contact 20 protrudes to the outside, it can come into contact with the terminal of the device to be charged. The charging terminal contact 20 contacts the terminal of the device to be charged, and transmits the charging current to the device to be charged.

充電端子２の素材はワイヤ線の為、板バネ端子に比べると、安価である。尚、バネ定数が小さい為、充電端子の動作領域に対して、端子の接触圧の変動量が少なく、常に理想的な接点圧を与えられる利点がある。   Since the material of the charging terminal 2 is a wire, it is less expensive than the leaf spring terminal. In addition, since the spring constant is small, there is an advantage that an ideal contact pressure can always be applied with a small amount of variation in the contact pressure of the terminal with respect to the operating region of the charging terminal.

充電端子２は一本のワイヤ線のフォーミング加工により形成している為、加工がし易い。   Since the charging terminal 2 is formed by forming a single wire, it is easy to process.

充電端子２は同一面に複数巻き接点を有する為、充電される機器の端子との接触面積が大きく、小さい異物が挟んでも、充電可能であり、充電性能が従来品より優れている。且つ、横方向の面積を増やすことにより、充電端子２は横方向の耐力が従来品より優れている。   Since the charging terminal 2 has a plurality of winding contacts on the same surface, the charging terminal 2 has a large contact area with the terminal of the device to be charged, and can be charged even when a small foreign object is caught, and the charging performance is superior to the conventional product. In addition, by increasing the lateral area, the charging terminal 2 is superior in lateral strength to the conventional product.

本実施例において充電端子接点２０は２重であるが、充電性能及び横方向に対する強度に応じて、２重巻き以上であれば、端子の接点数は問わない。   In this embodiment, the charging terminal contact 20 is double, but the number of contact points of the terminal is not limited as long as it is not less than double winding depending on the charging performance and the strength in the lateral direction.

以上説明した通り、本発明によれば、同一面に複数の接点が形成されるように一本のワイヤ線をフォーミング加工した充電性能が優れ、且つ横方向の耐力が優れる複数巻き接点を有するワイヤ端子構造を提供できる   As described above, according to the present invention, a wire having a plurality of winding contacts with excellent charging performance and excellent lateral strength, which is formed by forming a single wire to form a plurality of contacts on the same surface.
