この発明は、乾電池を電源として点火、出湯を行う湯沸器等の電装ボックスに関する。
【０００２】
【従来の技術】
従来、乾電池を電源として点火、出湯を行う湯沸器等にあっては、電源としての乾電池を収納する乾電池ケースＡ′と制御用基板を設置する基板ケースＢ′とを各別に設け、これらを配線６′、７′及びコネクタ８′を介して接続している（たとえば、図７参照）。
【０００３】
【発明が解決しようとする課題】
前記従来の技術では、乾電池ケースＡ′と基板ケースＢ′を接続するのに、コネクタ８′や配線６′、７′を必要とするため、接続部の接触抵抗により乾電池の電圧が有効に取り出せないし、また、配線も複雑化し、そのかみ込み等によるトラブルも多く、さらには、各別の乾電池ケースＡ′と基板ケースＢ′とを設置するのには広い設置スペースを必要とするなどの問題点があった。
【０００４】
この発明は、従来の技術の有する斯かる問題点に鑑み、配線やコネクタが不要で、しかも、コンパクト化でき、併せて、水滴等の侵入をも防止する電装ボックスの提供を目的としている。

【０００７】
上記課題を解決するこの発明の請求項２の電装ボックスは、請求項１において、乾電池ケースの端子を基板ケース内の基板に直接接続したことを特徴とする。
【０００８】
【作用】
上記構成を有するこの発明の電装ボックスは、乾電池ケースと、基板ケース及び基板ケースの蓋とが一体化されているので、配線やコネクタが不要となり、しかも、コンパクト化できる。
【０００９】
上記構成を有するこの発明の電装ボックスは、基板ケースと蓋との上部の合せ面に、段差による堰４、４’と、該堰４’を堰４側へ延長した庇状の突出部によるカバーとを設けて水滴等の侵入を防いだから、基板ケース上に水滴等が落ちてもこれが基板ケース内に侵入することはない。
【００１０】
上記構成を有するこの発明の電装ボックスは、乾電池ケース側の端子を基板ケース内の基板に直接接続したから、乾電池の電圧が有効に取り出せ、また、乾電池と基板の接続が簡単、確実に行いうる。
【００１１】
【実施例】
以下この発明による電装ボックスの一実施例について図面を参照して説明する。
【００１２】
図１〜図５はこの発明の電装ボックスの一例を示し、図６はこの発明の電装ボックスを元止式のガス湯沸器に適用した使用例を示したものであって、Ａは電源としての乾電池１を収納する乾電池ケースで、下面を開口８し上面内部には一方の端子金具６を備えた筒状のケース本体９と、上面に電池保持部１０を有し下面内部には他方の端子金具７を備えた蓋体１１とからなり、蓋体１１の電池保持部１０に挿着保持された乾電池１を蓋体１１の脱着と同時にケース本体９に対しケース本体９の下方から挿入、脱出できる構成となっている。
【００１３】
Ｃはケース本体９に対する蓋体１１の固定手段で、実施例では蓋体１１と一体の支持筒１１ａに係止凸起１２を先端一側に有し基端には操作ツマミ１３を備えた可動軸１４を左右へ所定の角度回動できるように挿設し、ケース本体９には前記係止凸起１２が係脱する係合段部１５を備えた筒体１６を設け、この筒体１６に可動軸１４を挿入して操作ツマミ１３で可動軸１４を所定の角度左右へ回動操作することで係止凸起１２が係合段部１５に係脱して、ケース本体９に対し蓋体１１の固定と固定解除とができるようになしている。３２は電装ボックスを器体に取付けるための取付け部で、前記ケース本体９と一体に設けられている。なお、実施例は２本の乾電池を用いる電装ボックスとし、前記固定手段Ｃと取付け部３２を２本の乾電池間に設けている。
【００１４】
Ｂは、機能部を制御するための基板２を取付け設置する基板ケースで、比較的浅い箱状となっており、その内壁の対向部に基板２を取付け保持する受段部１７と係合凸部１８とを備え、前記乾電池ケースＡの一側に一体に連設され、基板ケースＢに対し基板２が前記受段部１７と係合凸部１８に脱着できる構成となっている。なお、前記係合凸部１８は内面に斜面部１８ａを有しており、また、基板２には機能部品２ｅを備えている。
【００１５】
３は前記基板ケースＢの蓋で、基板ケースＢの開口側にヒンジ部１９により一体に連結され、この蓋３はヒンジ部１９を支点として片開き状に開閉できるように構成されている。なお、前記蓋３のヒンジ部１９の反対側には復元力をもつ係合フック２０を設け、この係合フック２０を基板ケースＢに設けた係止部２１に係脱することにより蓋３の閉止及び開放ができるようになしている。
【００１６】
前記蓋３の基板ケースＢとの合せ面には、段差ｈ_１、ｈ_２による堰４、４′と庇状の突出部ｌによるカバー５とを備えて基板ケースＢ内への水滴等の侵入を防いでいる。すなわち、図４に詳示されているように、基板ケースＢの接合部に該基板ケースＢの肉厚ｔ_１より高い段差ｈ_１による堰４を設け、かつ、蓋３の接合部には該蓋３の肉厚ｔ_２より高い段差ｈ_２による堰４′を設けるとともに、該堰４′を堰４側へ延長した庇状の突出部ｌによるカバー５を設けて、基板ケースＢ及び蓋３の肉厚ｔ_１、ｔ_２より一段高い堰４、４′による堰止めと、カバー５で基板ケースＢ側の堰４と蓋側の堰４′との突き合せ部の上面を覆うことで水滴等の侵入を防ぐ構成となっている。なお、前記水滴避けの堰４、４′及びカバー５は、実施例のように基板ケースＢと蓋３の上面にだけ設ければ所期の目的は達しうるが、ヒンジ部１９を除く三方のすべてに設けてもよい。
【００１７】
前記乾電池ケースＡの上面内部の端子金具６と基板２との接続手段として実施例は、基板２にハンダ付け等２ｄにより一端が固定された接続端子板２ｂと乾電池ケースＡ内の端子金具６とを接続端子板２ｂの他端に形成されたバーリングによるカシメ６ａ等により一体に連結し、乾電池ケースＡに備えた係合凸起６ｂの係合溝６ｃに接続端子板２ｂの両側縁が係合されるとともに、接続端子板２ｂを切り起して形成された係止爪２ｃが係合凸起６ｂの端面に係止されることにより、これらが取付け保持されるように設けて、基板ケースＢ内に設置される基板２と乾電池ケースＡ内の端子金具６とを直接接続した構成としている。
【００１８】
前記一体連結された接続端子板２ｂと端子金具６の組付けは、前記基板２の取付けと同時に行われる。すなわち、接続端子板２ｂと端子金具６を基板２とともに基板ケースＢ側から乾電池ケースＡ側へ接続端子板２ｂの両側縁を係合凸起６ｂの係合溝６ｃに嵌挿して移動させると、係止爪２ｃが係合溝６ｃをその復元力に抗して潜り抜けたところで係止爪２ｃがその復元力によりはね上ってこの係止爪２ｃが係合凸起６ｂの端面に係止される。したがって、接続端子板２ｂと端子金具６は、係合溝６ｃによる接続端子板２ｂの両側縁の係合保持と係止爪２ｃが係合凸起６ｂに係止されることによる保持とで位置決め固定されると同時に基板２もその側端縁２ａが受段部１７と係合凸部１８間に嵌めつけられて所定位置に取付けセットされる。
【００１９】
前記構成の乾電池ケースＡと基板ケースＢ及び基板ケースＢの蓋３は、水滴避けの堰４、４′及びカバー５とともに樹脂等で一体形成するものである。
【００２０】
図６（イ）、（ロ）において、Ｄはこの発明の電装ボックスで、器体側の取付板３４に前記取付け部３２により取付け設置される。２２は操作ボタン、２３はガス側本体、２４は水側本体、２５はメインバーナ、２６は集熱器、２７は防熱フード、２８はフレキシブル出湯管、２９はキッチンシャワー、３０はガス接続口、３１は給水接続口である。
【００２１】
前記構成において、電池交換時はケース本体９に対し蓋体１１を固定手段Ｃの操作ツマミ１３を所定の方向へ所定の角度回動操作して係止凸起１２と係合段部１５の係合を外して蓋体１１を下方へ脱出開放すると、蓋体１１の電池保持部１０に保持されている乾電池１も蓋体１１の開放と同時に取り出される。そこで、新しい乾電池１を電池保持部１０に挿着保持した後、この乾電池１を蓋体１１とともにケース本体９内に下方から所定の位置まで挿入し、操作ツマミ１３を所定の方向へ所定の角度回動操作して係止凸起１２を係合段部１５に係合すれば、乾電池１はそれぞれの端子金具６、７に確実に接して乾電池ケースＡ内に収納される。
【００２２】
基板ケースＢに対し基板２を取付けるときは、基板ケースＢの蓋３を開いて基板２を基板ケースＢ内に入れ、その両側端縁２ａを基板ケースＢの対向内壁部の係合凸起１８の斜面部１８ａに沿って滑らせて押し込めば、基板ケースＢの内壁が係合凸部１８の高さだけその復元力に抗して外方に変形し基板２は係合凸部１８を押しのけて受段部１７と係合凸部１８間に嵌めつけ保持される。このとき、基板２と一体の接続端子板２ｂと端子金具６も前述の理により所定の位置に取付け保持される。また、基板ケースＢから基板２を取外すときは、基板ケースＢの内壁をその復元力に抗して外方へ押して変形すれば、係合凸部１８による基板２の係合が解かれるため、受段部１７と係合凸部１８間から基板２を外すことができる。このとき、基板２と一体の接続端子板２ｂと端子金具６も、係合凸起６に対する係止爪２ｃの係止を外して基板２とともに取外すものである。
【００２３】
基板ケースＢに基板２を取付けた後、その蓋３を閉めると、基板ケースＢの堰４と蓋３の堰４′の対向内面が気密に当接し、しかも、この突き合せ部の上面をカバー５で覆うため、基板ケースＢ上に水滴等が落ちても堰４、４′及びカバー５により水滴等が基板ケースＢ内へ侵入するのを確実に防止する。
【００２４】
以上この発明の実施例について説明したが、この発明はこうした実施例に何等限定されるものではなく、この発明の要旨を逸脱しない範囲において、種々なる態様で実施し得ることは勿論である。たとえば、実施例では２本の乾電池を用いる電装ボックスを例示しているが、１本又は２本以上の乾電池を用いる電装ボックスにも適用できる。
【００２５】
【発明の効果】
以上説明したこの発明の電装ボックスによれば、乾電池ケースと基板ケース及び基板ケースの蓋とが一体化されているから、配線やコネクタが不要で、しかも、コンパクト化できるために器体への設置スペースは狭くてすみ、構造的にも簡略化される。
【００２６】
また、基板ケースと蓋との上部の合せ面に堰とカバーによる水滴避けを設けたので、基板ケース内への水滴等の侵入による基板の機能低下、故障等はなくなり、特に、この発明の電装ボックスを湯沸器に使用した場合に有益である。
【００２７】
さらに、この発明の電装ボックスによれば、乾電池ケース側の端子を基板ケース内の基板と直接接続したから、接触抵抗の影響がなく乾電池の電圧が有効に利用できる。また、乾電池と基板との接続が簡単、確実に行いうるから、余分な配線等が省略でき経済的である。

Even if water drops fall on the substrate case B, the weirs 4 and 4 'and the cover 5 reliably prevent the water drops from entering the substrate case B.
[0024]
Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention. For example, in the embodiment, an electrical box using two dry batteries is illustrated, but the present invention can be applied to an electrical box using one or two or more dry batteries.
