【００１２】
この実施の形態のバッテリ装置１は、図１〜図５の様に、バッテリ３の状態（残電状態や劣化状態）の検知やバッテリ３の放電電圧の安定化等を行う電子ユニット５とバッテリ３とを備えるものであり、有底枠体７を車両に固設し、電子ユニット５の外装ケース５ａをバッテリ３に横付けした状態で、バッテリ３及び外装ケース５ａの双方の下部を有底枠体７内に嵌合配置させ、この状態で、有底枠体７の前面（一側面）側からバッテリ３の上面及び外装ケース５ａの上面を跨いで有底枠体７の後面（他側面）側に至る様にして有底枠体７に締付バンド９を着脱自在に取り付けて該締付バンド９によりバッテリ３及び外装ケース５ａを有底枠体７に締付固定するものである。
【００１３】
ここでは、バッテリ３は、例えば直方体状に形成される。バッテリ３の上面上の左右両端側にはそれぞれ、バッテリ端子３ｂが配設される（図１及び図５参照）。各バッテリ端子３ｂは、例えばファストン端子（即ち、板状に形成され、その基端部がバッテリ３の上面に立設され、その先端部がバッテリ３の上面に平行に屈曲された端子）に形成され、その先端部が電子ユニット５側に向いて配設される。
【００１４】
電子ユニット５は、外装ケース５ａ内に回路基板５ｂが収容配設されて構成される。
【００１５】
外装ケース５ａは、回路基板５ｂが収容配設される箱状のケース本体部５ｃと、ケース本体部５ｃの上部から後方（側方）に張り出す様に延設され、該張出部分の下面に開口部５ｄが形成されたバッテリ端子収容部５ｅとから構成される。
【００１６】
ここでは、ケース本体部５ｃは、その後面（バッテリ３と対向する面）がバッテリ３の前面と同一寸法の略直方体状の箱状に形成される。バッテリ端子収容部５ｅは、ケース本体部５ｃの上面上の左右両端側にそれぞれ形成される。各バッテリ端子収容部５ｅは、互いに所定間隔（締付バンド９の幅と同じ幅の間隔）あけて形成される。
【００１７】
又、外装ケース５ａの左右両側面及び下面にはそれぞれ、バッテリ３の左右両側面及び下面に係合する係止部５ｆ，５ｇ，５ｈが形成される。ここでは、各係止部５ｆ，５ｇにより外装ケース５ａとバッテリ３との左右方向の相対位置が位置決めされる。係止部５ｈ及びバッテリ端子収容部５ｅにより、外装ケース５ａとバッテリ３との上下方向の相対位置が位置決めされる（図３参照）。
【００１８】

【００１９】
回路基板５ｂには、図５の様に、バッテリ３のバッテリ端子３ｂと電気接続する接続端子１１が実装される。

【００２１】
接続部１１ａは、それぞれ互いに上下に対向配置されて上下方向に弾性的に変位可能な接触部１１ｃ，１１ｄを構成する一対の弾性接触片１１ｅ，１１ｆを備える。各弾性接触片１１ｅ，１１ｆはそれぞれ、それらの間に挿入されたバッテリ端子３ｂに弾性的に接触し、そのバッテリ端子３ｂの相対的な上下方向の変位に応じてそのバッテリ端子３ｂによりそれらの接触部１１ｃ，１１ｄの位置が上下方向に弾性的に変位される。これにより、接続端子１１は、バッテリ端子３ｂとの接続状態で、該接触状態を保って、バッテリ端子３ｂと前後左右方向だけでなく上下方向にも相対的に位置ずれ可能に構成される。
【００２２】
より詳細には、上側の弾性接触片１１ｅは、例えば、バネ板部材により細長板状に形成され、その先端側が端子挿入側（下側）に廻ってその基端側に折り返えされ、その折り返し部分の中間部分が端子挿入側に盛り上げられて接触部１１ｃにされて形成される。下側の弾性接触片１１ｆは、バネ部材により細長板状に形成され、その中間部分が端子挿入側に盛り上げられて接触部１１ｄにされて形成される。各弾性接触片１１ｅ，１１ｆは、互いにそれらの基端側で一体に形成される。尚、上側（下側）の弾性接触片１１ｅ（１１ｆ）の形状を下側（上側）の弾性接触片１１ｆ（１１ｅ）の形状と上下対称の同様の形状にしてもよい。
【００２３】
この接続端子１１は、図５の様に、外装ケース５ａ内では、接触部１１ａの先端側がバッテリ端子収容部５ｅの張出方向（後方）に向けられ、支持部１１ｂにより支持されて外装ケース５ａのバッテリ端子収容部５ｅ内の所定位置に収容配置される。
【００２４】
有底枠体７は、例えば平面視矩形状の上面開放の底浅状の箱状に形成される。有底枠体７の収容凹部は、横付け状態のバッテリ３と電子ユニット５との下部が嵌合する様に形成される。
【００２５】
有底枠体７の外周側面には、有底枠体７を車両に固設（締結）する為の締結部７ａが側方に突出形成される。ここでは、締結部７ａは、例えば有底枠体７の外周側面上の略対角線上の各位置にそれぞれ１つずつ（計２つ）形成される。各締結部７ａには、その上下面を貫通する様に締結用ボルトの挿通用の貫通孔７ｂが形成される。各締結部７ａは、その底面の高さが有底枠体７の底面の高さと一致する様に形成される。
【００２６】
又、有底枠体７の相対する両側面（例えば前後面）にはそれぞれ、締付バンド９を着脱自在に取り付ける為の被係止部７ｃが形成される。ここでは、各被係止部７ｃはそれぞれ、先端が下方に向いた鉤状（即ち、その基端部分が有底枠体７の側面から側方に突出され、その先端部分側が下方に向けて屈曲された形状）に形成される。
【００２７】
締付バンド９は、伸縮自在の弾性部材（例えばゴム性部材）により形成された帯状のバンド部９ａと、バンド部９ａの長手方向の両端にそれぞれ取り付けられて有底枠体７の各被係止部７ｃと係合する係止部９ｂとを備えて構成される。ここでは、各係止部９ｂはそれぞれ、例えば金属性部材により例えば矩形状の環状に形成される。
【００２８】
次に、このバッテリ装置１に於けるバッテリ３及び電子ユニット５の取付手順を説明する。
【００２９】
ここでは、▲１▼バッテリ３に電子ユニット５を横付けした後、▲２▼バッテリ３及び電子ユニット５を車両に取り付ける。
【００３０】
上記▲１▼では、先ず、図７の様に、バッテリ３と電子ユニット５の外装ケース５ａとの間隔を所定間隔あけた状態で、外装ケース５ａのバッテリ端子収容部５ｅをバッテリ３の上面上に配置させて、バッテリ端子収容部５ｅの下面の開口部５ｄからバッテリ端子収容部５ｅ内にバッテリ３のバッテリ端子３ｂを収容する。そして、図８の様に、バッテリ端子収容部５ｅをバッテリ３の上面上を摺動させつつ外装ケース５ａとバッテリ３とを相対的に寄せて外装ケース５ａの後面とバッテリ３の前面とを当接させる。これにより、バッテリ端子収容部５ｅ内で、バッテリ端子３ｂの先端部が電子ユニット５側の接続端子１１の弾性接触片１１ｅ，１１ｆ間に挿入されてバッテリ端子３ｂと接続端子１１とが電気接続される。この外装ケース５ａとバッテリ３との当接状態では、外装ケース５ａの左右側面及び下面の各係止部５ｆ，５ｇ，５ｈがそれぞれバッテリ３の左右側面及び下面に係合する（図２及び図３参照）。これにより、外装ケース５ａの左右側面の係止部５ｆ，５ｇにより、バッテリ３と外装ケース５ａとの左右方向の相対的な位置ずれが防止され、外装ケース５ａの下面の係止部５ｈ及び上面のバッテリ端子収容部５ｅにより、バッテリ３と外装ケース５ａとの上下方向の相対的な位置ずれが防止される。この様にバッテリ３に電子ユニット５を横付けする。
【００３１】
上記▲２▼では、図１〜図４の様に、電子ユニット５が横付けされたバッテリ３を、電子ユニット５とバッテリ３との対向方向（前後方向）が有底枠体７の各被係止部７ｃの相対方向に一致する様にして車両に固設した有底枠体７内に嵌合配置させる。そして、締付バンド９のバンド部９ａをバッテリ３の上面及び外装ケース５ａの上面を跨がらせて外装ケース５ａの両バッテリ端子収容部５ｅの間を通し、該バンド部９ａの両端の係止部９ｂを有底枠体７の前後面の被係止部７ｂに係合させることにより、締付バンド９を有底枠体７に取り付ける。この状態では、締付バンド９のバンド部９ａは弾性的に伸長されており、その伸長に対する弾性復帰の縮みにより、電子ユニット５の上部とバッテリ３の上部とが互いに離れない様に寄せられ、電子ユニット５及びバッテリ３が有底枠体７内から抜けない様に有底枠体７に締付けられ、締付バンド９の係止部９ｂが上方に引っ張られて締付バンド９の係止部９ｂと有底枠体７の被係止部７ｃとが外れない様に係合される。この様にバッテリ３及び電子ユニット５を車両に取り付ける。
【００３２】
以上の様に構成されたバッテリ装置１によれば、有底枠体７を車両に固設し、電子ユニット５の外装ケース５ａをバッテリ３に横付けした状態で、バッテリ３及び外装ケース５ａの双方の下部を有底枠体７内に嵌合配置させ、この状態で、有底枠体７の前面（一側面）側からバッテリ３の上面及び外装ケース５ａの上面を跨いで有底枠体７の後面（他側面）側に至る様にして有底枠体７に締付バンド９を着脱自在に取り付けて該締付バンド９によりバッテリ３及び外装ケース５ａを有底枠体７に締付固定する為、バッテリ３及び電子ユニット５を一箇所にまとめて車両に取り付けることができる。
【００３３】
その際、有底枠体７の前面（一側面）側からバッテリ３の上面及び外装ケース５ａの上面を跨いで有底枠体７の後面（他側面）側に至る様にして有底枠体７に締付バンド９を着脱自在に取り付けて該締付バンド９によりバッテリ３及び外装ケース５ａを有底枠体７に締付固定する為、１つの締付バンド９により簡単な構造でバッテリ３及び電子ユニット５を車両に取り付けることができる。
【００３４】
又、締付バンド９は伸縮自在の弾性部材により形成される為、バッテリ３や電子ユニット５に寸法誤差があっても適切にバッテリ３及び電子ユニット５を有底枠体７に締付固定できる他、車両振動等が生じてもしっかりとバッテリ３及び電子ユニット５を有底枠体７に締結固定できる。
【００３５】
又、締付バンド９の両端部に係止部９ｂが設けられ、有底枠体７の前後面（側面）に被係止部７ｃが設けられ、係止部９ｂと被係止部７ｃとの係合により締付バンド９の端部が有底枠体７に取り付けられる為、簡単な構造で構成できて簡単な作業で着脱自在に締付バンド９を有底枠体７に取り付けることができる。
【００３６】
又、外装ケース５ａは、その上部から側方に張り出して形成されて下面に開口部５ｄが形成されたバッテリ端子収容部５ｅを有し、外装ケース５ａがバッテリ３に横付けされた状態で、バッテリ端子収容部５ｅがバッテリ３の上面上に配置してバッテリ３の上面のバッテリ端子３ｂを開口部５ｄからバッテリ端子収容部５ｅ内に収容し、バッテリ端子収容部５ｅ内でバッテリ端子３ｂと電子ユニット５の接続端子１１とを電気接続させる為、バッテリ端子３ｂと電子ユニット５の接続端子１１との電気接続部分を外部から保護でき、意匠性も向上できる。
【００３７】
又、接続端子１１は、それぞれ互いに上下方向に対向配置されてそれらの対向方向（上下方向）に弾性的に変位可能な接触部１１ｃ，１１ｄを構成し、それらの間に挿入されたバッテリ端子３ｂに弾性的に接触し、該バッテリ端子３ｂのそれらの対向方向の変位に応じて該バッテリ端子３ｂによりそれらの接触部１１ｃ，１１ｄの位置が弾性的に変位される一対の弾性接触片１１ｅ，１１ｆを備える為、バッテリ３と電子ユニット５とが車両振動等により上下方向に相対的にずれても、そのずれを弾性接触片１１ｅ，１１ｆの接触部１１ｃ，１１ｄの位置の弾性的な変位により吸収でき、これによりバッテリ３と電子ユニット５との間の電気接続部分に無理な力が掛かること無く適切な電気接続状態を確保できる。
【００３８】

As shown in FIGS. 1 to 5, the battery device 1 according to the embodiment includes an electronic unit 5 that detects the state of the battery 3 (remaining state or deterioration state), stabilizes the discharge voltage of the battery 3, and the like. 3 with the bottomed frame 7 fixed to the vehicle, and the lower part of both the battery 3 and the outer case 5a with the bottomed frame in a state where the outer case 5a of the electronic unit 5 is laid on the battery 3 sideways. In this state, the rear surface (the other side surface) of the bottomed frame 7 extends over the upper surface of the battery 3 and the upper surface of the outer case 5a from the front surface (one side surface) of the bottomed frame 7 in this state. A fastening band 9 is detachably attached to the bottomed frame 7 so as to reach the side, and the battery 3 and the outer case 5a are fastened and fixed to the bottomed frame 7 by the fastening band 9.
[0013]
Here, the battery 3 is formed, for example, in a rectangular parallelepiped shape. Battery terminals 3b are provided on both left and right sides on the upper surface of the battery 3 (see FIGS. 1 and 5). Each battery terminal 3b is formed as, for example, a Faston terminal (that is, a terminal formed in a plate shape, a base end of which is erected on the upper surface of the battery 3 and a distal end thereof is bent parallel to the upper surface of the battery 3). The front end is arranged facing the electronic unit 5 side.
[0014]
The electronic unit 5 is configured by housing and disposing a circuit board 5b in an outer case 5a.
[0015]
The outer case 5a extends in a box-shaped case main body 5c in which the circuit board 5b is housed and arranged, and extends rearward (sideward) from the upper portion of the case main body 5c. And a battery terminal accommodating portion 5e having an opening 5d formed therein.
[0016]
Here, the rear surface (the surface facing the battery 3) of the case main body 5c is formed in a substantially rectangular parallelepiped box shape having the same dimensions as the front surface of the battery 3. The battery terminal accommodating portions 5e are respectively formed on the left and right ends on the upper surface of the case main body 5c.

[0017]
Locking portions 5f, 5g, and 5h are formed on the left and right sides and the lower surface of the outer case 5a so as to be engaged with the left and right sides and the lower surface of the battery 3, respectively. Here, the relative positions of the outer case 5a and the battery 3 in the left-right direction are determined by the locking portions 5f and 5g.

[0019]
As shown in FIG. 5, a connection terminal 11 electrically connected to the battery terminal 3b of the battery 3 is mounted on the circuit board 5b.
[0020]
For example, as shown in FIG. 6, the connection terminal 11 is formed by extending a support portion 11b fixedly connected to the circuit board 5b from the base end side of the connection portion 11a connected to the battery terminal 3b.

Each of the elastic contact pieces 11e and 11f elastically contact the battery terminal 3b inserted between them, and the battery terminal 3b contacts the battery terminal 3b in accordance with the relative vertical displacement of the battery terminal 3b. The positions of the portions 11c and 11d are elastically displaced in the vertical direction. Thus, the connection terminal 11 is configured to be relatively displaceable not only in the front-rear and left-right directions but also in the vertical direction while maintaining the contact state in the connection state with the battery terminal 3b.
[0022]
