Description

本考案は、携帯情報機器や携帯電話等の携帯端末を充電するための充電装置に関し、特に、急速充電に適した充電装置に関する。   The present invention relates to a charging device for charging a portable terminal such as a portable information device or a mobile phone, and more particularly to a charging device suitable for rapid charging.

携帯情報機器や携帯電話等の携帯端末は、充電可能な充電池を内蔵し、この充電池の電力によって動作する。電池残量が少なくなれば、携帯端末を充電装置に装着し、家庭用のコンセントから充電装置を介して、携帯端末の充電池に充電している。特許文献１に示す充電装置は、携帯端末を充電装置に装着した時に、充電装置に取り付けられた板バネ製の充電装置側充電端子が、端末側充電端子の下面に沿って左右方向に往復移動して、接触表面の酸化皮膜等の絶縁性の被膜を除去してセルフクリーニングしている。しかし、特許文献１に示す従来の充電装置は、充電装置側充電端子が端末側充電端子の下面に一箇所で線接触するため、接触抵抗が不安定で、充電時の電流を大きくすることが難しいため、急速充電には適していない。   A portable terminal such as a portable information device or a mobile phone has a built-in rechargeable battery and operates with the power of the rechargeable battery. When the remaining battery level is low, the mobile terminal is attached to the charging device, and the rechargeable battery of the mobile terminal is charged from the household outlet via the charging device. In the charging device shown in Patent Document 1, when a portable terminal is attached to the charging device, the charging device-side charging terminal made of a leaf spring attached to the charging device reciprocates in the left-right direction along the lower surface of the terminal-side charging terminal. Then, an insulating film such as an oxide film on the contact surface is removed to perform self-cleaning. However, in the conventional charging device shown in Patent Document 1, since the charging device side charging terminal is in line contact with the lower surface of the terminal side charging terminal at one location, the contact resistance is unstable, and the current during charging may be increased. Because it is difficult, it is not suitable for quick charging.

図９は従来のプランジャー式の充電装置側充電端子を備えた充電装置を示し、携帯端末を充電装置に装着した状態を示す縦断面図である。図９に示すように、充電装置１００のハウジング１０１の円柱状空間１０２には、円筒状のチューブ１０３が内蔵されている。チューブ１０３の円柱状空間１０４には、プランジャー状の充電装置側充電端子１０５が上下方向に摺動可能に内嵌している。充電装置側充電端子１０５は、コイルばね１０６によって、常時上方に付勢されている。   FIG. 9 is a longitudinal sectional view showing a conventional charging device including a plunger-type charging device side charging terminal, and showing a state in which a portable terminal is mounted on the charging device. As shown in FIG. 9, a cylindrical tube 103 is built in the columnar space 102 of the housing 101 of the charging device 100. A plunger-shaped charging device side charging terminal 105 is fitted in the cylindrical space 104 of the tube 103 so as to be slidable in the vertical direction. The charging device side charging terminal 105 is always urged upward by a coil spring 106.

充電装置１００のハウジング１０１の上部に装着された携帯端末２００のハウジング２０１の下部には、底板２０２が固定されている。図９では、携帯端末２００のハウジング２０１の下端近傍だけを示している。底板２０２には、円柱状の端末側充電端子２０３が下方から挿入され、端末側充電端子２０３の下部には、大径フランジ部２０４が形成されている。端末側充電端子２０３は、携帯端末２００の図示しない充電池に電気的に接続されている。端末側充電端子２０３、充電装置側充電端子１０５は、金属等の導電性材料で形成されている。大径フランジ部２０４の上面と底板２０２との間には、防水用のＯリング２０５が挿入されている。また、ハウジング２０１と底板２０２との接合部には、防水用のＯリング２０６が挿入されている。充電装置側充電端子１０５の上端には、半球状の凸部１０７が形成され、凸部１０７の上端が大径フランジ部２０４の下面２０４Ａに点接触して、端末側充電端子２０３に電力を供給する。   A bottom plate 202 is fixed to the lower part of the housing 201 of the mobile terminal 200 mounted on the upper part of the housing 101 of the charging apparatus 100. FIG. 9 shows only the vicinity of the lower end of the housing 201 of the mobile terminal 200. A cylindrical terminal-side charging terminal 203 is inserted into the bottom plate 202 from below, and a large-diameter flange portion 204 is formed below the terminal-side charging terminal 203. The terminal side charging terminal 203 is electrically connected to a rechargeable battery (not shown) of the mobile terminal 200. The terminal side charging terminal 203 and the charging device side charging terminal 105 are formed of a conductive material such as metal. A waterproof O-ring 205 is inserted between the upper surface of the large-diameter flange portion 204 and the bottom plate 202. Further, a waterproof O-ring 206 is inserted into the joint between the housing 201 and the bottom plate 202. A hemispherical convex portion 107 is formed at the upper end of the charging device side charging terminal 105, and the upper end of the convex portion 107 is in point contact with the lower surface 204 </ b> A of the large diameter flange portion 204 to supply power to the terminal side charging terminal 203. To do.

図９に示す従来の充電装置１００は、端末側充電端子２０３と充電装置側充電端子１０５が１点で点接触しているため、接触抵抗が不安定で、充電時の電流を大きくすることが難しいため、急速充電には適していない。また、端末側充電端子２０３と充電装置側充電端子１０５が常時同一位置で接触しているため、酸化皮膜等の絶縁性の被膜を除去するセルフクリーニングができないため、接触不良が生じやすい。さらに、端末側充電端子２０３の取り付け部の防水に、２個の防水用のＯリング２０５、２０６が必要となるため、構造が複雑で、製造コストが上昇する要因となっている。   In the conventional charging device 100 shown in FIG. 9, since the terminal side charging terminal 203 and the charging device side charging terminal 105 are in point contact at one point, the contact resistance is unstable, and the current during charging may be increased. Because it is difficult, it is not suitable for quick charging. Further, since the terminal-side charging terminal 203 and the charging device-side charging terminal 105 are always in contact with each other at the same position, self-cleaning that removes an insulating film such as an oxide film cannot be performed, and contact failure tends to occur. Furthermore, since two waterproof O-rings 205 and 206 are required for waterproofing the attachment portion of the terminal-side charging terminal 203, the structure is complicated, which increases the manufacturing cost.

充電装置側充電端子３の側面３１Ａ、３１Ｂの下端は、通電板５２、５３、５４から離れているため、通電部材５から充電装置側充電端子３に電力は供給されない。従って、充電装置１に携帯端末７が装着されていない状態で、プラス側とマイナス側両方の充電装置側充電端子３の上端に金属片が誤って接触しても、短絡が生じることは無い。   Since the lower ends of the side surfaces 31 </ b> A and 31 </ b> B of the charging device side charging terminal 3 are separated from the energization plates 52, 53 and 54, power is not supplied from the energizing member 5 to the charging device side charging terminal 3. Therefore, even if a metal piece accidentally contacts the upper ends of both the positive and negative charging device side charging terminals 3 in a state where the portable terminal 7 is not attached to the charging device 1, a short circuit does not occur.

図４は、充電装置に携帯端末の装着が完了した状態を示す図１相当図、図５は、図４のＢ−Ｂ断面図、図６は、図５のＲ部拡大図である。図４〜図６に示すように、携帯端末７を充電装置１のハウジング２に装着して押し込むと、充電装置側充電端子３が圧縮コイルばね４の付勢力に抗して押し下げられる。端末側充電端子７１の下面７２Ａに線接触する左側の凸部３４は、充電装置側充電端子３の上部３２の幅Ｗ１の中央よりも左側に配置されている。従って、充電装置側充電端子３が圧縮コイルばね４の付勢力に抗して押し下げられると、充電装置側充電端子３は案内溝２１に案内されて、図５の反時計方向に揺動する。充電装置側充電端子３の揺動平面は、充電装置側充電端子３の側面３１Ａ、３１Ｂに平行である。   4 is a view corresponding to FIG. 1 showing a state where the portable terminal is completely attached to the charging device, FIG. 5 is a cross-sectional view taken along the line BB of FIG. 4, and FIG. 6 is an enlarged view of a portion R of FIG. As shown in FIGS. 4 to 6, when the portable terminal 7 is mounted and pushed into the housing 2 of the charging device 1, the charging device side charging terminal 3 is pushed down against the urging force of the compression coil spring 4. The left convex portion 34 that is in line contact with the lower surface 72 </ b> A of the terminal-side charging terminal 71 is disposed on the left side of the center of the width W <b> 1 of the upper portion 32 of the charging device-side charging terminal 3. Therefore, when the charging device side charging terminal 3 is pushed down against the urging force of the compression coil spring 4, the charging device side charging terminal 3 is guided by the guide groove 21 and swings counterclockwise in FIG. The swing plane of the charging device side charging terminal 3 is parallel to the side surfaces 31 </ b> A and 31 </ b> B of the charging device side charging terminal 3.

携帯端末７を充電装置１のハウジング２に所定距離Ｌ１だけ押し込むと、充電装置側充電端子３は図５の反時計方向に角度θだけ揺動し、右側の凸部３５の上端も端末側充電端子７１の下面７２Ａに線接触する。左側の凸部３４の上端は、下面７２Ａに接触したまま距離Ｌ２だけ左方に移動し、下面７２Ａとの接触面をセルフクリーニングする。従って、充電装置１のハウジング２に対して携帯端末７の装着が完了すると、左側の凸部３４の上端と右側の凸部３５の上端の両方が端末側充電端子７１の下面７２Ａに線接触する。   When the portable terminal 7 is pushed into the housing 2 of the charging device 1 by a predetermined distance L1, the charging device side charging terminal 3 swings counterclockwise in FIG. 5 by an angle θ, and the upper end of the right convex portion 35 is also charged on the terminal side. Line contact is made with the lower surface 72A of the terminal 71. The upper end of the left convex portion 34 moves to the left by a distance L2 while being in contact with the lower surface 72A, and self-cleans the contact surface with the lower surface 72A. Accordingly, when the mobile terminal 7 is completely attached to the housing 2 of the charging device 1, both the upper end of the left convex portion 34 and the upper end of the right convex portion 35 are in line contact with the lower surface 72 </ b> A of the terminal side charging terminal 71. .

図４に示すように、充電装置１のハウジング２に対して携帯端末７の装着が完了すると、充電装置側充電端子３の側面３１Ａ、３１Ｂの下端が、通電板５２、５３、５４に線接触する。その結果、通電部材５から充電装置側充電端子３に電力が供給され、携帯端末７の図示しない充電池が充電される。左側の凸部３４と右側の凸部３５の両方が端末側充電端子７１に線接触し、充電装置側充電端子３の下端が、通電部材５の複数箇所に線接触するため、接触抵抗が安定し、充電時の電流を大きくすることができるため、急速充電が可能となる。   As shown in FIG. 4, when the mobile terminal 7 is completely attached to the housing 2 of the charging device 1, the lower ends of the side surfaces 31 </ b> A and 31 </ b> B of the charging device side charging terminal 3 are in line contact with the current-carrying plates 52, 53 and 54. To do. As a result, electric power is supplied from the energizing member 5 to the charging device side charging terminal 3, and a rechargeable battery (not shown) of the portable terminal 7 is charged. Since both the left convex portion 34 and the right convex portion 35 are in line contact with the terminal side charging terminal 71 and the lower end of the charging device side charging terminal 3 is in line contact with a plurality of locations of the energization member 5, the contact resistance is stable. And since the electric current at the time of charge can be enlarged, rapid charge is attained.

携帯端末７の充電が完了したら、携帯端末７を充電装置１のハウジング２から取り外す。すると、充電装置側充電端子３が圧縮コイルばね４の付勢力によって押し上げられる。その結果、充電装置側充電端子３の側面３１Ａ、３１Ｂの下端が、通電板５２、５３、５４から離れるため、通電部材５から充電装置側充電端子３に電力は供給されなくなる。また、充電装置側充電端子３は図５の時計方向に角度θだけ揺動し、右側の凸部３５の上端が端末側充電端子７１の下面７２Ａから最初に離れる。次に、左側の凸部３４の上端が端末側充電端子７１の下面７２Ａから離れる。   When charging of the mobile terminal 7 is completed, the mobile terminal 7 is removed from the housing 2 of the charging device 1. Then, the charging device side charging terminal 3 is pushed up by the urging force of the compression coil spring 4. As a result, the lower ends of the side surfaces 31A and 31B of the charging device side charging terminal 3 are separated from the energizing plates 52, 53, and 54, so that no power is supplied from the energizing member 5 to the charging device side charging terminal 3. Further, the charging device side charging terminal 3 swings by the angle θ in the clockwise direction of FIG. 5, and the upper end of the right convex portion 35 is first separated from the lower surface 72 </ b> A of the terminal side charging terminal 71. Next, the upper end of the left convex portion 34 is separated from the lower surface 72 </ b> A of the terminal-side charging terminal 71.

左側の凸部３４の上端は、下面７２Ａに接触したまま距離Ｌ２だけ移動してから端末側充電端子７１の下面７２Ａから離れるため、下面７２Ａとの接触面をセルフクリーニングする。右側の凸部３５の上端は、左側の凸部３４の上端よりも後に端末側充電端子７１の下面７２Ａに接触し、左側の凸部３４の上端よりも先に端末側充電端子７１の下面７２Ａから離れる。従って、右側の凸部３５の上端には火花が発生しないため、右側の凸部３５の上端の接触部分の損傷や炭化物による接触不良を防止することができる。   Since the upper end of the left convex portion 34 moves by a distance L2 while being in contact with the lower surface 72A and then moves away from the lower surface 72A of the terminal-side charging terminal 71, the contact surface with the lower surface 72A is self-cleaned. The upper end of the right convex portion 35 is in contact with the lower surface 72A of the terminal side charging terminal 71 after the upper end of the left convex portion 34, and the lower surface 72A of the terminal side charging terminal 71 is ahead of the upper end of the left convex portion 34. Get away from. Therefore, since no spark is generated at the upper end of the right convex portion 35, it is possible to prevent damage to the contact portion at the upper end of the right convex portion 35 and poor contact due to carbide.
