【発明の属する技術分野】
この発明は、ミニディスクプレーヤやヘッドホンステレオなどのポータブル電子機器に設けられた開閉式の電池蓋に連動する電池用端子の構造に係り、詳しくは、導電性支持部と、導電性支持部に立設された軸部材と、軸部材に回動可能に支持される導電性接触板とを備え、導電性接触板の基端部に導電性支持部に当接するための当接部を設けることにより、例え導電性接触板の基端部の軸部材への圧入が弱くても、常に当接部の先端は導電性支持部に当接するので、電気的に良好に接続することができ、接点不良を確実に防止することができる電池用端子構造に関するものである。
【0002】
【従来の技術】
ミニディスクプレーヤやヘッドホンステレオなどのポータブル電子機器には、電池を収納する収納部を開閉する回動式の電池蓋が設けられており、この電池蓋の裏面側には収納する電池の正極端子又は負極端子に接続するための電池用端子が設けられている。
【0003】
図14はこのような電池用端子の構成例を示す概略正面図、図15はその概略平面図である。端子部材31は、ベース板32と、ベース板32に立設されたヒンジ軸33と、ヒンジ軸33に一端が軽圧入され回動可能なヒンジ35から概略構成され、すべて導電性を有する金属部材からなっている。
【0004】
ヒンジ35の基端には円筒部35aが形成され、この円筒部35aがヒンジ軸33に軽圧入される。ヒンジ35の左右方向略中央には電池36の正極端子36aに当接するための突起35bが突設されている。ベース板32はネジ38によりプリント基板39にネジ止め固定され、プリント基板39の図示せぬ接点と接続するようになっている。
【0005】
【発明が解決しようとする課題】
ところで、上述のような端子部材31では、電池36の正極端子36aからの電気は、ヒンジ35の突起35bからヒンジ軸33、ベース板32を介してプリント基板39の接点に伝達されるので、ヒンジ軸33に軽圧入されるヒンジ35の円筒部35aが、各部品の寸法公差によるばらつきや、ユーザーの使用により、軽圧入部にガタが生じると、接点不良が発生する虞があった。
【0006】
また、ヒンジ軸33の外径寸法に比してヒンジ35の円筒部35aの内径寸法がやや小さく、圧入するのにかなりの力を要する場合には、スムーズに組み立てることができず、組立性が悪いという問題があった。
【0007】
そこで、本発明は、組立性が良く、部品の寸法公差や振動等による耐久性により、ヒンジ軸とヒンジとの圧接が緩んでも、電気的に良好に接続することができ、接点不良を確実に防止することができる電池用端子構造を提供することを目的とするものである。
【0008】
【課題を解決するための手段】
本発明に係る電池用端子構造は、電池を収納する収納部を開閉する回動式電池蓋に連動する電池用端子の構造であって、前記収納部の開口近傍に設けられた導電性支持部と、この導電性支持部に立設された軸部材と、この軸部材に基端部が回動可能に支持され、先端部が前記電池の一方の極に圧接する導電性接触板とを備え、前記導電性接触板の基端部に前記導電性支持部に当接するための当接部を設けたことを特徴とするものである。
【0009】
本発明に係る電池用端子構造では、導電性接触板の基端部に導電性支持部に当接するための当接部が設けられているので、例え部品の寸法公差や振動等による耐久性により、軸部材と導電性接触板の基端部との圧接にガタが生じても、常に当接部の先端は導電性支持部に当接するので、電気的に良好に接続することができ、接点不良を確実に防止することができる。
【0010】
【発明の実施の形態】
以下、本発明に係る電池端子の実施の形態の一例について、図面を参照して詳細に説明する。図1は本発明の実施の形態としての電池端子を適用したミニディスクプレーヤの全体斜視図である。
【0011】
図1に示すように、ミニディスクプレーヤ1の装置本体2には、その後側に配設された図示せぬヒンジ部を介して開閉蓋3が開閉可能に取り付けられている。開閉蓋3の裏面側にはミニディスクの保護ケースであるカートリッジケースを収納するためのディスクホルダ5が図示せぬヒンジ部を介して装置本体2に開閉可能に支持されている。開閉蓋3の前部左右方向略中央には係止片3aが形成されており、この係止片3aに対応する装置本体2部位にはフック6が左右方向にスライド可能に設けられている。
【0012】
フック6は装置本体2の前面左右方向略中央に配置されたイジェクトボタン7に連動するように構成されている。イジェクトボタン7をスライドさせることにより、フック6もスライドし、開閉蓋3及びディスクホルダ5が開放可能となっている。更に、装置本体2の前面の右側には電池蓋9が後述するヒンジ部27を介して装置本体2に開閉可能に取り付けられている。
【0013】
図2は電池蓋9を開放した状態の斜視図である。電池蓋9はヒンジ部27を介して略90度回動し、電池蓋9が電池収納部12を閉止する状態において、左右方向にスライドするように構成されている。電池収納部12には電池13が収納される。電池蓋9はその裏面側で、電池13の正極端子13aに当接するための電池端子である正極端子部材15に左右方向にスライド可能に取り付けられている。従って、電池蓋9はヒンジ部27により回動可能であると共に、左右方向にスライド可能となっている。
【0014】
図3は端子部材15及び電池収納部12を示す平面図であり、点線は電池蓋9が開放された状態を示している。メカシャーシ16の側方に電池収納部12が形成されている。電池収納部12の内部には電池13の負極端子13bが負極端子部材17に対応し、正極端子13aが正極端子部材15に対応するように挿入される。負極端子部材17はプリント基板18にネジ止め固定されプリント基板18の接点に接続され、正極端子部材(以下、端子部材と称す)15は図示せぬプリント基板にネジ20により固定されこのプリント基板の接点に接続されている。
【0015】
図4は本発明に係る端子部材の分解斜視図である。端子部材15は、導電性支持部であるベース板22と、ベース板22に立設される軸部材であるヒンジ軸23と、ヒンジ軸23に回動可能に支持される導電性接触板であるヒンジ24と、ヒンジ24に取り付けられる弾性を有する圧接部材25から概略構成され、すべて導電性を有する金属部材からなっている。そして、ヒンジ軸23とヒンジ24からヒンジ部27が形成される。
【0016】
本発明は、電池蓋9の開閉に伴ってヒンジ24及び圧接部材25が回動しても、常に圧接部材25の一端がベース板22に当接するようにして、従来のように電池の一方の極からの電気をヒンジ軸23を介してベース板22に伝達する必要がないので、ヒンジ軸23とヒンジ24との嵌め合いが緩くても、接点不良が発生しないようにしたものである。
【0017】
ベース板22は図示せぬプリント基板にネジ20でネジ止め固定するためのバーリング加工された取付孔22aが開けられている。ベース板22を図示せぬプリント基板にネジ20でネジ止め固定することにより、ベース板22とプリント基板の接点とが導通するようになっている。
【0018】
図5はヒンジ軸23を立設したベース板22を示し、(a)はその平面図、(b)はその正面図である。ベース板22にはネジ20のネジ部を挿通するためのバーリング加工された取付孔22aが開けられている。ベース板22の片側には段差部22bが設けられ、この段差部22bにはヒンジ軸23を嵌着するための孔22cが開けられている。ベース板22の側端の孔22cの周部には圧接部材25の後述する当接部25a-1が当接しないための切欠22dが設けられている。
【0019】
ヒンジ軸23は、孔22cに挿入されるための基端部23aと、基端部23aより大径の鍔部23bと、鍔部23bより小径の軸部23cとから形成されている。ヒンジ軸23の基端部23aがベース板22の孔22cに挿入され、かしめられると共に、鍔部23bが孔22cの周部に当接するようになっている。
【0020】
図6はヒンジ24を示し、(a)はその正面図、(b)はその平面図である。ヒンジ24は横長の板形状であり、基端にヒンジ軸23の軸部23cに軽圧入されるための円筒部24aが形成され、中央より基端側には圧接部材25をかしめるための孔24bと、圧接部材25が回動しないように係止するための係止突部24cが設けられている。ヒンジ24の中央部には圧接部材25の突起部25dを進出させるための角穴24dが開けられており、ヒンジ24の先端部には電池蓋9をスライドさせるためのガイドとなるガイド爪部24eが形成されている。
【0021】
ヒンジ軸23の軸部23cにはヒンジ24の筒部24aが軽圧入され、筒部24aの一端はヒンジ軸23の鍔部23bに常に当接するようになっている。
【0022】
図7は圧接部材25を示し、(a)はその正面図、(b)はその平面図である。圧接部材25は基端に半円筒部25aが形成され、中央部から先端側はU字形に分岐し、U字形の一方には圧接部材25をヒンジ24にかしめるための孔25bと、ヒンジ24の係止突部24cと係止するための係止溝25cとが形成され、U字形の他方には、角穴24dに進出して電池13の正極端子13aに圧接するための弾性を有する突起部25dが形成されている。圧接部材25の半円筒部25aのベース板22側にはベース板22に当接するための当接部25a-1が突設されている。
【0023】
図8はヒンジ24に圧接部材25を取り付けた状態を示し、(a)はその正面図、(b)はその平面図である。ヒンジ24の円筒部24aに圧接部材25の半円筒部25aを軽圧入し、ヒンジ24の孔24bと圧接部材25の孔25bを位置合わせし、ヒンジ24の係止突部24cを圧接部材25の係止溝25cに係止させ、孔24bと孔25bをかしめ加工すると、圧接部材25の突起部25dはヒンジ24の角穴24dから突出した状態となる。
【0024】
圧接部材25を取り付けたヒンジ24をヒンジ軸23の軸部23cに軽圧入すると、圧接部材25の当接部25a-1はヒンジ軸23の鍔部23bより外側に位置し、かつベース板22の段差部22bに圧接するようになっている。
【0025】
次に、電池蓋9を開閉した場合の端子部材15の動きについて説明する。図9は電池蓋9を開いた状態の端子部材15を示す平面図である。端子部材15のヒンジ24及び圧接部材25が外側に回動して、圧接部材25の当接部25a-1はベース板22の切欠22dに進出した位置にある。図10はこの時の当接部25a-1とベース板22の切欠22dとの位置関係を示す模式図である。ここで、当接部25a-1の先端は、ベース板22の段差部22bの上面より距離D(例えば、0.3mm)だけ切欠22d内に進出するようになっている。これにより、電池蓋9を開くと、ヒンジ24及び圧接部材25も開く方向へ回動し、当接部25a-1の先端が切欠22d内に進出するので、比較的小さな力で電池蓋9及びヒンジ24及び圧接部材25を回動させることができる。
【0026】
図11は電池蓋9を閉じた状態の端子部材15を示す平面図である。電池蓋9を閉じると、端子部材15のヒンジ24及び圧接部材25が内側に回動して、圧接部材25の当接部25a-1はベース板22の切欠22dから移動して段差部22bに当接する位置にある。図12はこの時の当接部25a-1とベース板22の段差部22bとの位置関係を示す模式図である。ここで、当接部25a-1の先端は、ベース板22の段差部22bの上面に当接するので、距離Dだけ持ち上げられることになり、ベース板22の段差部22bの上面に圧接した状態となる。このため、電池蓋9が閉じた状態では、当接部25a-1の先端はベース板22と電気的に良好に接続することができる。
【0027】
従って、電池蓋9を閉じた状態では、圧接部材25の当接部25a-1がベース板22に圧接した状態にあるので、例えヒンジ24の円筒部24aのヒンジ軸23への軽圧入が弱くても、当接部25a-1の先端とベース板22を電気的に良好に接続することができ、接点不良を確実に防止することができる。
【0028】
圧接部材25に弾性を有する突起部25dが設けられているので、ミニディスクプレーヤ1が振動しても、突起部25dと電池13の正極端子13aとは接触不良となることはなく、振動に対しても確実に接触を保つことができる。
【0029】
また、電池蓋9を開く方向へ回動すると、ヒンジ24及び圧接部材25も外側に回動して、圧接部材25の当接部25a-1の先端が切欠22d内に進出するので、比較的小さな力で電池蓋9及びヒンジ24及び圧接部材25を回動させることができ、操作性を向上させることができる。
【0030】
次に、第2の実施の形態の電池端子について説明する。図13に示すように、第2の実施の形態の電池端子のヒンジ29はヒンジと圧接部材が一体に成形されている。ヒンジ29は横長の板形状であり、基端にヒンジ軸23の軸部23cに軽圧入されるための円筒部29aが形成され、円筒部29aのベース板22側にはベース板22に当接するための当接部29a-1が突設されている。更に、円筒部29aには切欠29a-2が設けられ、当接部29a-1が段差部22bに当接したとき、円筒部29aがバネ性を持ってたわむように構成されている。
【0031】
ヒンジ29の中央部には電池13の正極端子13aに圧接するための弾性を有する圧接部29bが形成され、先端部には電池蓋9をスライドさせるためのガイドとなるガイド爪部29cが形成されている。これにより、ヒンジと圧接部材を一体化することができ、部品点数の削減と、組立作業の容易化が図れる。
【0032】
なお、上述第1及び第2の実施の形態では、圧接部材25又はヒンジ29の圧接部29bが電池13の正極端子13aに当接するとしたが、これに限らず、負極端子に当接するとしてもよいことは勿論である。正面角形の電池を用いたが、これに限らず、正面円形の電池を用いてもよいことは勿論である。
【0033】
【発明の効果】
以上説明したように、本発明によれば、導電性接触板の基端部に導電性支持部に当接するための当接部が設けられているので、例え部品の寸法公差や振動等による耐久性により、軸部材と導電性接触板の基端部との圧接にガタが生じても、常に当接部の先端は導電性支持部に当接しているので、電気的に良好に接続することができ、接点不良を確実に防止することができる。
【0034】
軸部材と導電性接触板の基端部との圧接が緩くても、常に当接部の先端は導電性支持部に当接し、電気的に良好に接続することができるので、部品の寸法公差を比較的緩くすることができ、圧入するのが容易で、スムーズに組み立てることができ、組立性を向上させることができる。
【0035】
導電性接触板の先端部に電池の一方の極に圧接するための弾性を有する圧接部が設けられている場合には、電池収納部に振動が加わっても、確実に圧接部が電池の一方の極に当接し、振動による接点不良を確実に防止することができる。
【0036】
導電性支持部の導電性接触板の当接部に当接する部分に切欠が設けられている場合には、導電性接触板が開く方向に回動して電池の一方の極に当接しない位置にある時には、当接部が切欠に進出するので、比較的小さな力で電池蓋及び導電性接触板を回動させることができ、操作性の向上を図ることができる。

[0022]
FIG. 7 shows the pressure contact member 25, (a) is a front view thereof, and (b) is a plan view thereof. A semi-cylindrical portion 25a is formed at the base end of the pressure contact member 25, and a distal end side branches from the center portion into a U shape. A hole 25b for caulking the pressure contact member 25 to the hinge 24 and a hinge 24 on one side of the U shape. A locking groove 25c for locking and a locking groove 25c for locking are formed. On the other side of the U-shape, a protrusion having elasticity for advancing into the square hole 24d and press-contacting with the positive electrode terminal 13a of the battery 13 is formed. A portion 25d is formed. On the base plate 22 side of the semi-cylindrical portion 25 a of the pressure contact member 25, a contact portion 25 a-1 for contacting the base plate 22 is projected.
[0023]
FIG. 8 shows a state in which the pressure contact member 25 is attached to the hinge 24, (a) is a front view thereof, and (b) is a plan view thereof. The semi-cylindrical portion 25a of the press contact member 25 is lightly press-fitted into the cylindrical portion 24a of the hinge 24, the hole 24b of the hinge 24 and the hole 25b of the press contact member 25 are aligned, and the locking projection 24c of the hinge 24 is connected to the press contact member 25. When the holes 24b and the holes 25b are caulked by being locked in the locking grooves 25c, the protruding portions 25d of the pressure contact member 25 are projected from the square holes 24d of the hinge 24.
[0024]
When the hinge 24 to which the pressure contact member 25 is attached is lightly press-fitted into the shaft portion 23c of the hinge shaft 23, the contact portion 25a-1 of the pressure contact member 25 is positioned outside the flange portion 23b of the hinge shaft 23 and the base plate 22 It is configured to come into pressure contact with the stepped portion 22b.
[0025]
Next, the movement of the terminal member 15 when the battery cover 9 is opened and closed will be described. FIG. 9 is a plan view showing the terminal member 15 with the battery cover 9 open. The hinge 24 and the pressure contact member 25 of the terminal member 15 are rotated outward, and the contact portion 25 a-1 of the pressure contact member 25 is in a position where it has advanced into the notch 22 d of the base plate 22. FIG. 10 is a schematic diagram showing the positional relationship between the contact portion 25a-1 and the notch 22d of the base plate 22 at this time. Here, the tip of the abutting portion 25a-1 advances from the upper surface of the stepped portion 22b of the base plate 22 into the notch 22d by a distance D (for example, 0.3 mm). Thus, when the battery lid 9 is opened, the hinge 24 and the pressure contact member 25 are also rotated in the opening direction, and the tip of the contact portion 25a-1 advances into the notch 22d. The hinge 24 and the pressure contact member 25 can be rotated.
[0026]
FIG. 11 is a plan view showing the terminal member 15 with the battery cover 9 closed. When the battery cover 9 is closed, the hinge 24 and the pressure contact member 25 of the terminal member 15 rotate inward, and the contact portion 25a-1 of the pressure contact member 25 moves from the notch 22d of the base plate 22 to the stepped portion 22b. It is in the position to contact. FIG. 12 is a schematic diagram showing the positional relationship between the contact portion 25a-1 and the step portion 22b of the base plate 22 at this time. Here, since the tip of the contact portion 25a-1 contacts the upper surface of the step portion 22b of the base plate 22, it is lifted by a distance D, and is in a state of being in pressure contact with the upper surface of the step portion 22b of the base plate 22. Become. For this reason, when the battery cover 9 is closed, the tip of the contact portion 25a-1 can be electrically connected to the base plate 22 in an excellent manner.
[0027]
Therefore, when the battery lid 9 is closed, the contact portion 25a-1 of the pressure contact member 25 is in pressure contact with the base plate 22, so that light press-fitting into the hinge shaft 23 of the cylindrical portion 24a of the hinge 24 is weak. However, the tip of the contact portion 25a-1 and the base plate 22 can be electrically connected well, and contact failure can be reliably prevented.
[0028]
Since the pressure contact member 25 is provided with an elastic protrusion 25d, even if the mini disc player 1 vibrates, the protrusion 25d and the positive terminal 13a of the battery 13 do not cause poor contact, and the vibration is not affected. However, contact can be reliably maintained.
[0029]
Further, when the battery cover 9 is rotated in the opening direction, the hinge 24 and the pressure contact member 25 are also rotated outward, and the tip of the contact portion 25a-1 of the pressure contact member 25 advances into the notch 22d. The battery lid 9, the hinge 24, and the pressure contact member 25 can be rotated with a small force, and the operability can be improved.
[0030]
Next, the battery terminal of 2nd Embodiment is demonstrated. As shown in FIG. 13, the hinge 29 and the pressure contact member of the battery terminal hinge 29 of the second embodiment are integrally formed. The hinge 29 has a horizontally long plate shape, and a cylindrical portion 29a is formed at the base end to be lightly press-fitted into the shaft portion 23c of the hinge shaft 23. The cylindrical portion 29a contacts the base plate 22 on the base plate 22 side. A contact portion 29a-1 for projecting is provided. Further, the cylindrical portion 29a is provided with a notch 29a-2, and the cylindrical portion 29a is configured to bend with a spring property when the contact portion 29a-1 contacts the stepped portion 22b.
[0031]
An elastic pressure contact portion 29b is formed at the center of the hinge 29 so as to be pressed against the positive electrode terminal 13a of the battery 13, and a guide claw portion 29c serving as a guide for sliding the battery lid 9 is formed at the tip. ing. Thereby, the hinge and the pressure contact member can be integrated, and the number of parts can be reduced and the assembling work can be facilitated.
[0032]
In the first and second embodiments described above, the pressure contact member 25 or the pressure contact portion 29b of the hinge 29 is in contact with the positive electrode terminal 13a of the battery 13. However, the present invention is not limited thereto, and may be in contact with the negative electrode terminal. Of course it is good. Although a front square battery is used, the present invention is not limited to this, and it is needless to say that a front circular battery may be used.
[0033]
【The invention's effect】
As described above, according to the present invention, since the contact portion for contacting the conductive support portion is provided at the base end portion of the conductive contact plate, durability due to, for example, dimensional tolerance of components or vibrations. Even if there is a backlash in the pressure contact between the shaft member and the base end of the conductive contact plate, the tip of the contact portion is always in contact with the conductive support portion. And contact failure can be reliably prevented.
[0034]
Even if the pressure contact between the shaft member and the base end of the conductive contact plate is loose, the tip of the abutting part always abuts the conductive support part and can be connected electrically well. Can be made relatively loose, can be easily press-fitted, can be assembled smoothly, and can be assembled.
[0035]
When the pressure contact part having elasticity for pressing the one electrode of the battery is provided at the tip of the conductive contact plate, even if vibration is applied to the battery housing part, the pressure contact part is surely connected to one side of the battery. The contact failure due to vibration can be surely prevented.
[0036]
The position where the conductive contact plate rotates in the opening direction and does not come into contact with one of the battery poles when a portion of the conductive support portion that comes into contact with the contact portion of the conductive contact plate is provided. In this case, since the contact portion advances into the notch, the battery lid and the conductive contact plate can be rotated with a relatively small force, and the operability can be improved.
