Description

本発明は、たとえば単３電池と単４電池のように、長さが異なる二次電池を充電できる充電器に関する。   The present invention relates to a charger capable of charging secondary batteries having different lengths, such as AA batteries and AAA batteries.

単３電池と単４電池の両方を脱着できるように装着して充電できる充電器は開発されている。この充電器は、長さが異なる二次電池を装着して、両端の電極に充電端子を接触できる構造としている。たとえば、二次電池を装着する嵌着凹部に、二次電池の縦方向に移動できるホルダーを設け、このホルダーに充電端子を固定したものが開発されている。ホルダーは弾性的に縦方向に移動して、単３電池と単４電池の電極に接触される。さらに、充電端子を設けているホルダーを回転できる構造として、単３電池と単４電池の電極に接触するものも開発されている。

単３電池と単４電池の両方を充電するために、ホルダーを摺動させ、あるいは回転させる充電器は、充電端子を設けているホルダーの機構が複雑になって製造コストが高くなる。また、摺動したり回転したりするホルダーは、接触不良による故障が多くなる。それは、ホルダーの充電端子を充電回路に接続するためのブラシと摺動接点とが接触不良を起こし、あるいはリード線が切断して通電できなくなるからである。   In order to charge both AA batteries and AAA batteries, a charger that slides or rotates the holder is complicated in the mechanism of the holder provided with the charging terminal, and the manufacturing cost increases. In addition, the holder that slides and rotates frequently increases due to poor contact. This is because the brush for connecting the charging terminal of the holder to the charging circuit and the sliding contact cause a contact failure, or the lead wire is cut and cannot be energized.

この欠点は、たとえば、単３電池と単４電池を脱着できるように嵌着する専用の嵌着凹部を設けることで解消できる。ただ、この構造にすると充電器が大きくなる欠点がある。大きな充電器は持ち運びに不便であるばかりでなく、ケースが大きくなって製造コストも高くなる。   This drawback can be eliminated by providing a dedicated fitting recess for fitting so that the AA battery and the AAA battery can be detached. However, this structure has a drawback that the charger becomes large. A large charger is not only inconvenient to carry, but also increases the case size and manufacturing cost.

The short battery fitting recess 5 is provided with the bottom surface of the long battery fitting recess 4 inclined downward from the first charging terminal 6 toward the second charging terminal 7. Since the short battery fitting recess 5 has an inclined bottom surface, the short battery 3 mounted here is also set in an inclined posture. The short battery fitting recess 5 is shorter than the long battery fitting recess 4, and a third charging terminal 8 that contacts the electrode of the short battery 3 is provided in the middle of the bottom surface of the long battery fitting recess 4. In the illustrated charger, the first charging terminal 6 is in contact with the + electrode of the long battery 2, so the third charging terminal 8 is a charging terminal that is in contact with the − electrode of the short battery 3.

長電池嵌着凹部４に装着される長電池２は、第１充電端子６と第２充電端子７に接触して充電され、短電池嵌着凹部５に装着される短電池３は、第１充電端子６と第３充電端子８に接続して充電される。したがって、第１充電端子６と第２充電端子７と第３充電端子８は、ケース１に内蔵される充電回路（図示せず）に接続されて、長電池２と短電池３を充電する。図の充電器は、第１充電端子６を充電回路の＋側に、第２充電端子７と第３充電端子８を充電回路の−側に接続している。   The long battery 2 mounted in the long battery insertion recess 4 is charged by contacting the first charging terminal 6 and the second charging terminal 7, and the short battery 3 mounted in the short battery insertion recess 5 is the first The battery is charged by connecting to the charging terminal 6 and the third charging terminal 8.

The short battery 3 is pressed against the first charging terminal 6 in a posture inclined with respect to the long battery 2. The first charging terminal 6 shown in FIG. 3 has a portion in contact with the electrode of the short battery 3 so that the first charging terminal 6 does not push the short battery 3 and push out from the short battery fitting recess 5. It is parallel to the electrode surface. The first charging terminal 6 having this structure presses against the electrode surface of the inclined short battery 3 in the axial direction, that is, in the vertical direction, and prevents the short battery 3 from being pushed out from the short battery fitting recess 5. The first charging terminal 6 is an elastic metal wire or an elastic metal plate, and its lower end is fixed to the case 1.

図の充電器は、第２充電端子７と第３充電端子８を１本の弾性金属線や弾性金属板で構成している。弾性金属線は、一方の端部を山形に折曲して第２充電端子７として、折曲部である第２充電端子７を長電池２の電極に接触させている。弾性金属線は他方の端部を第３充電端子８として、短電池３の電極に接触させている。弾性金属板は、途中をケース１内に配線してケース１の定位置に固定して、第２充電端子７と第３充電端子８となる部分をケース１から外部に突出させている。   In the charger shown in the figure, the second charging terminal 7 and the third charging terminal 8 are formed of one elastic metal wire or elastic metal plate. One end of the elastic metal wire is bent into a mountain shape to form the second charging terminal 7, and the second charging terminal 7, which is a bent portion, is brought into contact with the electrode of the long battery 2. The elastic metal wire is in contact with the electrode of the short battery 3 with the other end serving as the third charging terminal 8. The elastic metal plate is wired in the case 1 in the middle and fixed at a fixed position of the case 1, and the portions to be the second charging terminal 7 and the third charging terminal 8 are projected from the case 1 to the outside.

図４ないし図６は、本発明の実施例を示すものではなく、長電池と短電池を充電する充電器の参考例を示すもので、この充電器は、第１充電端子６を長電池２と短電池３の−側電極に接触させて、第２充電端子７と第３充電端子８を長電池２と短電池３の＋側電極に接触させる。これ等の図に示す充電器の第１充電端子６は、短電池３の電極に接触する部分を、短電池嵌着凹部５の底面に向かって、図６において下方に向かって、短電池３の電極面から離れる方向に傾斜させている。この構造の第１充電端子６は、短電池３が短電池嵌着凹部５から押し出されるのを防止できる。   4 to 6 do not show embodiments of the present invention, but show reference examples of a charger for charging a long battery and a short battery. In this charger, the first charging terminal 6 is connected to the long battery 2. The second charging terminal 7 and the third charging terminal 8 are brought into contact with the + side electrode of the long battery 2 and the short battery 3. The first charging terminal 6 of the charger shown in these figures is such that the portion in contact with the electrode of the short battery 3 is directed toward the bottom surface of the short battery fitting recess 5 and downward in FIG. It is made to incline in the direction away from the electrode surface. The first charging terminal 6 having this structure can prevent the short battery 3 from being pushed out of the short battery fitting recess 5.

さらに、これ等の図に示す充電器も、第２充電端子７と第３充電端子８を１本の金属線や金属板で構成している。この金属板は全体をほぼＬ字状に折曲して、上部を第２充電端子７として長電池２の電極に、下部を下方に折曲して第３充電端子８として短電池３の電極に接触させている。金属板は途中をケース１に固定している。この図の充電器は、長電池２を水平に支持するために、図において長電池嵌着凹部４の右端部の底部に、長電池２を下から支持する支持部９を設けている。この支持部９は短電池３を装着するときに邪魔にならないように、短電池３が接触しない位置に配設している。   Further, in the charger shown in these drawings, the second charging terminal 7 and the third charging terminal 8 are constituted by one metal wire or metal plate. This metal plate is generally bent in an L shape, the upper part is the second charging terminal 7 and the lower battery 2 is bent downward, and the lower part is the third charging terminal 8 and the short battery 3 is the electrode. Is in contact with The metal plate is fixed to the case 1 in the middle. In order to support the long battery 2 horizontally, the charger of this figure is provided with a support portion 9 for supporting the long battery 2 from below at the bottom of the right end of the long battery fitting recess 4 in the figure. The support portion 9 is disposed at a position where the short battery 3 is not in contact with the support portion 9 so as not to interfere with the mounting of the short battery 3.

以上の充電器は、第２充電端子７と第３充電端子８とを１本の金属線等で構成して、互いに連結しているので、充電回路を簡単にできる特長がある。ただ、第２充電端子と第３充電端子とを別々の充電端子とし、別々に充電回路に接続することもできる。この充電器は、長電池と短電池の両方を、最適な充電電流に調整して短時間で急速充電することができる。   The above charger has a feature that the charging circuit can be simplified because the second charging terminal 7 and the third charging terminal 8 are formed of a single metal wire and connected to each other. However, the second charging terminal and the third charging terminal can be separate charging terminals and can be separately connected to the charging circuit. This charger can adjust both the long battery and the short battery to an optimum charging current and can be rapidly charged in a short time.
