【発明の属する技術分野】
本発明は、電気部品組立体の電気接続構造に関し、特に、基体の一面側に位置決め配置される電気部品組立体に第1接続端子が突設され、前記電気部品組立体を覆いつつ前記基体の一面に取付けられるカバーに第2接続端子が設けられ、第1および第2接続端子が抵抗溶接で接合される電気部品組立体の電気接続構造の改良に関する。
【0002】
【従来の技術】
従来、このような電気接続構造は、たとえば特開2000−255415号公報で開示されており、このものでは、コイルを含むコイル組立体に一対の第1接続端子が突設され、電磁弁のソレノイド部をコイル組立体とともに構成するガイド筒が一面から突出する基体に、コイル組立体を覆うカバーが取付けられ、該カバーに設けられた一対の第2接続端子と、前記両第1接続端子とが抵抗溶接で接合されている。
【0003】
【発明が解決しようとする課題】
ところで、コイル組立体は基体の一面から突出するガイド筒を嵌合せしめることで基体の一面側に位置決め配置されるのであるが、このコイル組立体と基体の一面に取付けられるカバーとの間の公差を吸収するために、上記従来のものでは、コイル組立体を構成する部品間に比較的大きなクリアランスを設定している。すなわち上記従来のもののコイル組立体は、ガイド筒を嵌合せしめるボビンと、該ボビンに巻装されるコイルと、コイルを囲繞してボビンに装着される磁路枠とを含むのであるが、コイルの外周および磁路枠の内周間に比較的大きなクリランスを設定することで、上記組付け時の公差を吸収するようにしている。このため、コイル組立体が比較的大型化してしまうだけでなく、磁路枠のガイド筒との磁気的結合を確実とするためにボビンおよび磁路枠間にばねが必要となる。
【0004】
本発明は、かかる事情に鑑みてなされたものであり、電気部品組立体を構成する部品間で組付け公差を吸収することを不要として、電気部品組立体の小型化を可能とした電気部品組立体の電気接続構造を提供することを目的とする。
【0005】
【課題を解決するための手段】
上記目的を達成するために、請求項1記載の発明は、基体の一面側に位置決め配置される電気部品組立体に第1接続端子が突設され、前記電気部品組立体を覆いつつ前記基体の一面(15)に取付けられるカバーに第2接続端子が設けられ、第1および第2接続端子が抵抗溶接で接合される電気部品組立体の電気接続構造において、略L字状に屈曲した第2接続端子が前記カバーに設けられ、先端部を第2接続端子の幅方向中央部に対向させる第1接続端子が第2接続端子よりも幅を狭くして電気部品組立体から直線状に延出され、第1および第2接続端子のうち少なくとも第1接続端子が、打ち抜き成形時に凸曲面となる側を第2接続端子側に向けるようにして打ち抜き成形されることを特徴とする。
【0006】
このような構成によれば、第1接続端子の幅を第2接続端子よりも狭く設定することで第1接続端子の変形を可能とし、組付け時の公差を第1接続端子の変形で吸収することを可能となる。このため、電気部品組立体を構成する部品間で組付公差を吸収することが不要であり、電気部品組立体の各部品間にクリアランスを設定することを不要として電気部品組立体を小型化することができる。また第1および第2接続端子の接触面積を比較的小さくして抵抗溶接時の接触抵抗を高くし、溶接強度を高めることができ、しかも電極への各接続端子の接触点での接触抵抗よりも溶接面での接触抵抗を大きくし、溶接面を発熱し易くすることができる。
【0007】
請求項2記載の発明は、上記請求項1記載の発明の構成に加えて、前記第2接続端子に、その全幅にわたって第1接続端子側に突出した突出部が設けられ、該突出部および第1接続端子がプロジェクション溶接されることを特徴とし、かかる構成によれば、第2接続端子に対する第1接続端子の幅方向の公差ずれを吸収して突出部に第1接続端子を確実に接触させることができる。しかも溶接接合面の電流密度を高くして接合面の温度をピーク温度として確実な接合を可能とするとともに、短時間の溶接で母材への熱影響を最小限に抑えることができる。すなわち突出部が第2接続端子の幅方向の一部に設けられている場合には、溶接時の熱で突出部が軟化して潰れやすいので電流を集中させ難く、大電流を必要とし、突出部の軟化に伴って電極移動量も大きくなるので通電時間が長くなり、周辺の母材に熱影響が生じる可能性があった。それに対し、突出部が第2接続端子の全幅にわたって設けられている場合には、突出部のうち第1接続端子との接触面の両側に第1接続端子に接触していない部分があるので、電流を集中させても突出部が軟化して潰れることはなく、したがって溶接接合面の電流密度を最も高くしてピーク温度を溶接接合面に定めることができ、電極移動量も少なくして短時間の溶接が可能となるのである。
【0008】
請求項3記載の発明は、上記請求項2記載の発明の構成に加えて、前記突出部が、第1接続端子側に滑らかに彎曲した形状に形成されることを特徴とし、かかる構成によれば、プロジェクション溶接時に応力が集中して突出部が第1接続端子側に食い込まないようにして、良好な溶接状態を得ることができる。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態を、添付の図面に示した本発明の実施例に基づいて説明する。
【0011】
図1〜図9は本発明の第1実施例を示すものであり、図1は車両用ブレーキ装置のブレーキ液圧回路図、図2はブレーキ液圧制御装置の平面図、図3は図2の3−3線拡大断面図、図4は図3の4−4線に沿う第1樹脂成形体の平面図、図5は図4の5−5線断面図、図6は相互に接合された状態にある第1および第2接続端子の斜視図、図7は接続端子のプロジェクション溶接時の状態を示す断面図、図8は図7の8−8線断面図、図9は接続端子の打ち抜き成形状態を示す断面図である。
【0012】
先ず図1において、タンデム型のマスタシリンダMは、車両運転者がブレーキペダルPに加える踏力に応じたブレーキ液圧を発生する第1および第2出力ポート1A,1Bを備えており、左前輪用車輪ブレーキ2A、右後輪用車輪ブレーキ2B、右前輪用車輪ブレーキ2Cおよび左後輪用車輪ブレーキ2Dと、前記第1および第2出力ポート1A,1Bに個別に接続された第1および第2出力液圧路3A,3Bとの間にブレーキ液圧制御装置4が設けられる。
【0013】
ブレーキ液圧制御装置4は、左前輪用車輪ブレーキ2A、右後輪用車輪ブレーキ2B、右前輪用車輪ブレーキ2Cおよび左後輪用車輪ブレーキ2Dに個別に対応した常開型電磁弁5A〜5Dと、各常開型電磁弁5A〜5Dにそれぞれ並列に接続されるチェック弁7A〜7Dと、前記各車輪ブレーキ2A〜2Dに個別に対応した常閉型電磁弁6A〜6Dと、第1および第2出力液圧路3A,3Bにそれぞれ個別に対応した第1および第2リザーバ8A,8Bと、第1および第2リザーバ8A,8Bに吸入側がそれぞれ接続されるとともに吐出側が第1および第2出力液圧路3A,3Bに接続される第1および第2ポンプ9A,9Bと、両ポンプ9A,9Bを駆動する共通1個の電動モータ10と、第1および第2ポンプ9A,9Bの吐出側がそれぞれ接続される第1および第2ダンパ11A,11Bと、各ダンパ11A,11BおよびマスタシリンダM間にそれぞれ設けられる第1および第2オリフィス12A,12Bとを備える。
【0014】
常開型電磁弁5A,5Bは、第1出力液圧路3Aと左前輪用車輪ブレーキ2Aおよび右後輪用車輪ブレーキ2Bとの間に設けられ、常開型電磁弁5C,5Dは、第2出力液圧路3Bと右前輪用車輪ブレーキ2Cおよび左後輪用車輪ブレーキ2Dとの間に設けられる。
【0015】
また各チェック弁7A〜7Dは、対応する車輪ブレーキ2A〜2DからマスタシリンダMへのブレーキ液の流れを許容するようにして、各常開型電磁弁5A〜5Dに並列に接続される。
【0016】
常閉型電磁弁6A、6Bは、左前輪用車輪ブレーキ2Aおよび右後輪用車輪ブレーキ2Bと第1リザーバ8Aとの間に設けられ、常閉型電磁弁6C,6Dは、右前輪用車輪ブレーキ2Cおよび左後輪用車輪ブレーキ2Dと第2リザーバ8Bとの間に設けられる。
【0017】
このようなブレーキ液圧制御装置4は、各車輪がロックを生じる可能性のない通常ブレーキ時には、マスタシリンダMおよび車輪ブレーキ2A〜2D間を連通するとともに車輪ブレーキ2A〜2Dおよびリザーバ8A,8B間を遮断する。すなわち各常開型電磁弁5A〜5Dが消磁、開弁状態とされるとともに各常閉型電磁弁6A〜6Dが消磁、閉弁状態とされ、マスタシリンダMの第1出力ポート1Aから出力されるブレーキ液圧は常開型電磁弁5Aを介して左前輪用車輪ブレーキ2Aに作用するとともに、常開型電磁弁5Bを介して右後輪用車輪ブレーキ2Bに作用する。またマスタシリンダMの第2出力ポート1Bから出力されるブレーキ液圧は、常開型電磁弁5Cを介して右前輪用車輪ブレーキ2Cに作用するとともに常開型電磁弁5Dを介して左後輪用車輪ブレーキ2Dに作用する。
【0018】
上記ブレーキ中に車輪がロック状態に入りそうになったときに、ブレーキ液圧制御装置4は、ロック状態に入りそうになった車輪に対応する部分でマスタシリンダMおよび車輪ブレーキ2A〜2D間を遮断するとともに車輪ブレーキ2A〜2Dおよびリザーバ8A,8B間を連通する。すなわち常開型電磁弁5A〜5Dのうちロック状態に入りそうになった車輪に対応する常開型電磁弁が励磁、閉弁されるとともに、常閉型電磁弁6A〜6Dのうち上記車輪に対応する常閉型電磁弁が励磁、開弁される。これにより、ロック状態に入りそうになった車輪のブレーキ液圧の一部が第1リザーバ8Aまたは第2リザーバ8Bに吸収され、ロック状態に入りそうになった車輪のブレーキ液圧が減圧されることになる。
【0019】
またブレーキ液圧を一定に保持する際に、ブレーキ液圧制御装置4は、車輪ブレーキ2A〜2DをマスタシリンダMおよびリザーバ8A,8Bから遮断する状態となる。すなわち常開型電磁弁5A〜5Dが励磁、閉弁されるとともに、常閉型電磁弁6A〜6Dが消磁、閉弁されることになる。さらにブレーキ液圧を増圧する際には、常開型電磁弁5A〜5Dが消磁、開弁状態とされるともに、常閉型電磁弁6A〜6Dが消磁、閉弁状態とされればよい。
【0020】
このように各常開型電磁弁5A〜5Dおよび各常閉型電磁弁6A〜6Dの消磁・励磁を制御することにより、車輪をロックさせることなく、効率良く制動することができる。
【0021】
ところで、上述のようなアンチロックブレーキ制御中に、電動モータ10は回転作動し、この電動モータ10の作動に伴って第1および第2ポンプ9A,9Bが駆動されるので、第1および第2リザーバ8A,8Bに吸収されたブレーキ液は、第1および第2ポンプ9A,9Bに吸入され、次いで第1および第2ダンパ11A,11Bを経て第1および第2出力液圧路3A,3Bに還流される。このようなブレーキ液の還流によって、第1および第2リザーバ8A,8Bのブレーキ液の吸収によるブレーキペダルPの踏み込み量の増加を防ぐことができる。しかも第1および第2ポンプ9A,9Bの吐出圧の脈動は第1および第2ダンパ11A,11Bならびに第1および第2オリフィス12A,12Bの働きにより抑制され、上記還流によってブレーキペダルPの操作フィーリングが阻害されることはない。
【0022】
図2および図3において、ブレーキ液圧制御装置4は、たとえばアルミニウム合金等によりブロック状に形成される基体15を備えるものであり、この基体15に、各常開型電磁弁5A〜5B、各常閉型電磁弁6A〜6D、各チェック弁7A〜7D、第1および第2リザーバ8A,8B、第1および第2ポンプ9A,9B、ならびに第1および第2ダンパ11A,11B等が設けられる。また基体15の一面15aには合成樹脂製のカバー16が、複数たとえば4個のボルト17…により締結され、該カバー16とは反対側で基体15の他面に電動モータ10が締結される。
【0023】
常開型電磁弁5A〜5Dおよび常閉型電磁弁6A〜6Dは相互に平行に並んで基体15に配設される。
【0024】
常開型電磁弁5A〜5Dは、弁部18およびソレノイド部19で構成されるものであり、基体15の一面15aに開口するようにして該基体15に設けられる装着孔20に弁部18が収容、固定され、ソレノイド部19は基体15の一面15aから突出する。
【0025】
弁部18は、磁性金属により段付きの円筒状に形成される弁ハウジング21を備えるものであり、この弁ハウジング21は、基体15に設けられた装着孔20に嵌合される。装着孔20の開口端寄り内面には弁ハウジング21に係合して該弁ハウジング21の装着孔20からの離脱を阻止する止め輪22が嵌着される。また弁ハウジング21の外面の軸方向に間隔をあけた2個所にはOリング23と、チェック弁7A,7Bとして機能するカップシール24とが装着される。それらOリング23およびカップシール24間で基体15および弁ハウジング21間には環状室25が形成され、該環状室25に臨む部分で弁ハウジング21の外周にはフィルタ26が装着される。
【0026】
基体15には、第1および第2出力液圧路3A,3Bの一方に連なるとともに前記装着孔20の内端に同軸に開口する液圧路27と、前記環状室25に通じるとともに各車輪ブレーキ2A〜2Dの1つに通じる液圧路28とが設けられる。而して前記環状室25および液圧路27間に介在するカップシール24は、環状室25すなわち各車輪ブレーキ2A〜2D側から液圧路27すなわちマスタシリンダM側へのブレーキ液の流通を許容するチェック弁7A,7Bとして機能するようにして常開型電磁弁5A〜5Dの弁ハウジング21…に装着されている。
【0027】
このような弁部18は、前記液圧路27,28間の連通・遮断をソレノイド部19の消磁・励磁に応じて切換えるように作動する。
【0028】
ソレノイド部19は、前記弁部18の弁体に連動、連結される可動コア(図示せず)の移動をガイドするようにして前記弁ハウジング21に連設されるガイド筒30と、ガイド筒30を嵌合せしめる電気部品組立体としてのコイル組立体35とで構成される。
【0029】
コイル組立体35は、前記ガイド筒30を嵌合させる嵌合孔31aを中心部に有して合成樹脂により円筒状に形成されるボビン31と、該ボビン31に巻装されるコイル32と、コイル32を囲繞するとともにボビン31の両端でガイド筒30に磁気的に結合するようにしてボビン31に装着される磁路枠33とを備える。
【0030】
ガイド筒30は、弁ハウジング21の装着孔20への装着状態で、基体15の一面15aから突出されており、このガイド筒30を嵌合孔31aに嵌合せしめることで、コイル組立体35が基体15の一面15a側に位置決め配置されることになる。
【0031】
常閉型電磁弁6A〜6Dは、弁部38およびソレノイド部39で構成されるものであり、基体15の一面15aに開口するようにして該基体15に設けられる装着孔40に弁部38が収容され、ソレノイド部39は基体15の一面15aから突出する。
【0032】
弁部38は、段付きの円筒状に形成される弁ハウジング41を備えるものであり、この弁ハウジング41は、基体15に設けられた装着孔40に嵌合される。装着孔40の開口端寄り内面には弁ハウジング41に係合して該弁ハウジング41の装着孔40からの離脱を阻止する止め輪42が嵌着される。また弁ハウジング41の外面の軸方向に間隔をあけた2個所には環状のシール部材43,44が装着される。それらのシール部材43,44間で基体15および弁ハウジング41間には環状室45が形成され、該環状室45に臨む部分で弁ハウジング41の外周にはフィルタ46が装着される。
【0033】
前記環状室45は車輪ブレーキ2A〜2Dの1つに通じるものであり、基体15には、両リザーバ8A,8Bのいずれかに通じる液圧路47が、装着孔40の内端に開口するようにして設けられる。
【0034】
このような弁部38は、前記環状室45および液圧路47間の遮断・連通をソレノイド部39の消磁・励磁に応じて切換えるように作動する。
【0035】
ソレノイド部39は、前記弁部38の弁体に連動、連結される可動コア(図示せず)の移動をガイドするようにして前記弁ハウジング41に連設されるガイド筒48と、前記常開型電磁弁5A〜5Dのソレノイド部19におけるコイル組立体35と同様のコイル組立体35とで構成される。
【0036】
カバー16は、各常開型電磁弁5A〜5Dにおけるソレノイド部19…、各常閉型電磁弁6A〜6Dにおけるソレノイド部39…を収納するとともに、第1および第2リザーバ8A,8Bの一部、ならびに第1および第2ダンパ11A,11Bの一部を臨ませる収納室49を基体15との間に形成するようにして、基体15の一面15aに締結されている。しかもカバー16の基体15側端縁には、該基体15の一面15aに弾発的に接触する無端状のシール部材50が装着される。
【0037】
カバー16は、合成樹脂により横断面長方形状の筒形に形成される第1樹脂成形体51の一端に、第1樹脂成形体51の一端開口部を塞ぐ形状で合成樹脂により形成される第2樹脂成形体52が振動溶着されて成るものである。
【0038】
図4および図5を併せて参照して、カバー16における第1樹脂成形体51内の中間部には、各常開型電磁弁5A〜5Dの各ソレノイド部19…、ならびに第1〜第4常閉型電磁弁6A〜6Dの各ソレノイド部39…にそれぞれ個別に対応した矩形状の開口部53…,54……を有する平面状の壁部55が、基体15の一面15aに対向するようにして一体に形成される。
【0039】
一方、各常開型電磁弁5A〜5Dが備える各ソレノイド部19…の先端部は前記開口部53…に挿入され、各常閉型電磁弁6A〜6Dが備える各ソレノイド部39…の先端部は前記開口部54…に挿入される。
【0040】
しかもソレノイド部19…,39…が備えるコイル組立体35…におけるボビン31…からは、コイル32に連なる一対の第1接続端子56…が、各開口部53…,54…内を上方に延びるようにして突出される。
【0041】
前記壁部55には、各常開型電磁弁5A〜5Dに個別に対応する導電金属製のバスバー57…と、各常閉型電磁弁6A〜6Dに個別に対応する導電金属製のバスバー58…と、各常開型電磁弁5A〜5Dおよび各常閉型電磁弁6A〜6Dに共通に対応する単一の導電金属製の共通バスバー59とが埋設される。
【0042】
各バスバー57…,58…,59の一端は、第2接続端子60…として形成されるものであり、開口部53…にはバスバー57…,59の第2接続端子60,60がそれぞれ対をなして突出され、また開口部54…には、バスバー58…、59の第2接続端子60,60がそれぞれ対をなして突出される。しかも第2接続端子60…は、各コイル組立体35…の第1接続端子56…に対向するようにして略L字状に形成される。
【0043】
また各バスバー57…,58…,59の他端は、壁部55の上方で第1樹脂成形体51に固定的に支持される基板61に隣接した位置で第1樹脂成形体51の表面に露出して並設され、これらのバスバー57…,58…,59の他端は、基板61上の電気回路(図示せず)にアルミワイヤーのボンディング等により電気的に接続される。
【0044】
カバー16には、基体15よりも側方に突出したカプラ部16aが一体に設けられており、このカプラ部16a内に並設される外部接続用端子(図示せず)を一端に備える複数のバスバー62…の他端も、前記基板61に隣接した位置で第1樹脂成形体51の表面に露出して並設され、基板61上の電気回路にアルミワイヤーのボンディング等により電気的に接続される。
【0045】
ところで、常開型電磁弁5A〜5Dおよび常閉型電磁弁6A〜6Dの各コイル組立体35…は、図6で示すように、それらのコイル組立体35…から一対ずつ突出される第1接続端子56…と、それらのコイル組立体35…を覆うカバー16に設けられた一対ずつ複数組(この実施例では8組)の第2接続端子60…とが、抵抗溶接たとえばプロジェクション溶接により接合されることで前記カバー16に吊持されるものである。
【0046】
図7および図8において、プロジェクション溶接時に、第1および第2接続端子56,60は一対の電極63,64間に挟まれ、両電極63,64間に矢印で示すように電流が流される。
【0047】
しかも第1接続端子56の幅W1は、第2接続端子60の幅W2よりも小さく(W1<W2)設定されている。また第2接続端子60には、その全幅にわたって第1接続端子56側に突出した突出部60aが設けられており、この突出部60aは、第1接続端子56側に滑らかに彎曲した形状に形成されており、該突出部60aが第1接続端子56にプロジェクション溶接される。
【0048】
ところで、第1および第2接続端子56,60のうち少なくとも第1接続端子56(この実施例では両方)は、図9で示すように、銅板等の導電性を有する金属板素材65を、ダイ66およびパンチ67による打ち抜き成形で形成されるものであり、この打ち抜き成形完了時に、第1および第2接続端子56,60においてダイ66とは反対側の面は凸曲面(所謂だれ面)となるものであり、第1および第2接続端子56,60は、前記凸曲面となる側が溶接面となるように配置される。
【0049】
次にこの第1実施例の作用について説明すると、常開型電磁弁5A〜5Dおよび常閉型電磁弁6A〜6Dのソレノイド部19…,39…が基体15の一面15aから突出され、各ソレノイド部19…,39…を覆って前記一面15aに取り付けられる合成樹脂製のカバー16には、各ソレノイド部19…,39…に電気的に接続されるバスバー57…,58…,59を埋設せしめた平面状の壁部55が一体に設けられるのであるが、該壁部55には、各ソレノイド部19…,39…の先端をそれぞれ挿入させる複数の開口部53…,54…が設けられている。
【0050】
したがって各ソレノイド部19…,39…の先端を壁部55の開口部53…,54…に挿入することで、基体15の一面15aから壁部55までの距離を比較的小さくし、カバー16の高さも比較的小さくすることができ、これによりブレーキ液圧制御装置4の小型化が可能となる。
【0051】
ところで、各バスバー57…,58…,59を各ソレノイド部19…,39…に電気的に接続するにあたっては、各ソレノイド部19…,39…の一部を構成するコイル組立体35…に設けられて該コイル組立体35…から突出する一対の第1接続端子56,56…と、各バスバー57…,58…,59に一体に形成された第2接続端子60,60…とが抵抗溶接で接合される。しかも各コイル組立体35…を覆って前記一面15aに取付けられるカバー16側の第2接続端子60,60…に第1接続端子56,56…が接合された状態では、各コイル組立体35…がカバー16に吊持されることになり、カバー16を基体15に取付ける際に、カバー16に吊持されたコイル組立体35…に基体15の一面15aから突出したガイド筒30,48が嵌合することになり、その組付け時の公差を吸収する必要がある。
【0052】
このため本発明では、第1接続端子56…の幅W1が、第2接続端子60…の幅W2よりも小さく設定されている。これにより、第1接続端子56…の変形を可能とし、組付け時の公差を第1接続端子56…の変形で吸収することが可能となる。この結果、コイル組立体35…を構成する部品間で組付け公差を吸収することが不要であり、コイル組立体35…の各部品間にクリアランスを設定することを不要としてコイル品組立体35…を小型化することができる。しかもカバー16…で吊持されているコイル組立体35…に振動が作用したときに、比較的細いことで第2接続端子60…よりも強度が弱くなる第1接続端子56…がコイル組立体35…側すなわち荷重点側にあることで、第1接続端子56…に作用する力を小さく抑えることができる。また第1および第2接続端子56…,60…の接触面積を比較的小さくして抵抗溶接時の接触抵抗を高くして溶接強度を高めることができる。
【0053】
また第2接続端子60には、その全幅にわたって第1接続端子56側に突出した突出部60aが設けられており、第2接続端子60の突出部60aおよび第1接続端子56がプロジェクション溶接されるので、第2接続端子60に対する第1接続端子56の幅方向の公差ずれを吸収して突出部60aに第1接続端子56を確実に接触させることができる。しかも溶接接合面の電流密度を高くして接合面の温度をピーク温度として確実な接合を可能とするとともに、短時間の溶接で母材への熱影響を最小限に抑えることができる。すなわち突出部60aが第2接続端子60の幅方向の一部に設けられている場合には、溶接時の熱で突出部60aが軟化して潰れやすいので電流を集中させ難く、大電流を必要とし、突出部60aの軟化に伴って電極移動量も大きくなるので通電時間が長くなり、周辺の母材に熱影響が生じる可能性がある。それに対し、突出部60aが第2接続端子60の全幅にわたって設けられている場合には、突出部60aのうち第1接続端子56との接触面の両側に第1接続端子56に接触していない部分があるので、電流を集中させても突出部60aが軟化して潰れることはなく、したがって溶接接合面の電流密度を最も高くしてピーク温度を溶接接合面に定めることができ、電極移動量も少なくして短時間の溶接が可能となるのである。
【0054】
しかも前記突出部60aが、第1接続端子56側に滑らかに彎曲した形状に形成されるので、プロジェクション溶接時に応力が集中して突出部60aが第1接続端子56側に食い込まないようにして、良好な溶接状態を得ることができる。
【0055】
さらに第1および第2接続端子56,60のうち少なくとも第1接続端子56(この実施例では両方)が、打ち抜き成形されるとともにその打ち抜き成形時に凸曲面となる側を溶接面として配置されるので、電極63,64への各接続端子56,60の接触点での接触抵抗よりも溶接面での接触抵抗を大きくし、溶接面を発熱し易くすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to an electrical connection structure of an electrical component assembly, and in particular, a first connection terminal protrudes from an electrical component assembly positioned and arranged on one surface side of the base, and covers the electrical component assembly while The present invention relates to an improvement in the electrical connection structure of an electrical component assembly in which a second connection terminal is provided on a cover attached to one surface, and the first and second connection terminals are joined by resistance welding.
[0002]
[Prior art]
Conventionally, such an electrical connection structure is disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-255415. In this structure, a pair of first connection terminals protrudes from a coil assembly including a coil, and a solenoid of a solenoid valve A cover that covers the coil assembly is attached to a base body from which a guide tube that constitutes a part together with the coil assembly protrudes from one surface, and a pair of second connection terminals provided on the cover, and the first connection terminals. Joined by resistance welding.
[0003]
[Problems to be solved by the invention]
By the way, the coil assembly is positioned and arranged on one surface side of the substrate by fitting a guide tube protruding from one surface of the substrate, but the tolerance between the coil assembly and the cover attached to the one surface of the substrate. In order to absorb this, in the above-mentioned conventional one, a relatively large clearance is set between the parts constituting the coil assembly. That is, the conventional coil assembly includes a bobbin for fitting the guide tube, a coil wound around the bobbin, and a magnetic path frame surrounding the coil and mounted on the bobbin. By setting a relatively large clearance between the outer circumference of the magnetic path and the inner circumference of the magnetic path frame, the tolerance at the time of assembling is absorbed. For this reason, not only the coil assembly becomes relatively large, but also a spring is required between the bobbin and the magnetic path frame in order to ensure magnetic coupling with the guide tube of the magnetic path frame.
[0004]
The present invention has been made in view of such circumstances, and it is not necessary to absorb assembly tolerances between the components constituting the electrical component assembly, and the electrical component assembly that enables downsizing of the electrical component assembly. An object is to provide a three-dimensional electrical connection structure.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, according to a first aspect of the present invention, a first connection terminal protrudes from an electrical component assembly positioned and arranged on one surface side of the substrate, and covers the electrical component assembly while the first connection terminal covers the electrical component assembly. In the electrical connection structure of the electrical component assembly in which the second connection terminal is provided on the cover attached to the one surface (15), and the first and second connection terminals are joined by resistance welding, the second bent in a substantially L shape. A connection terminal is provided on the cover, and the first connection terminal whose tip is opposed to the central portion in the width direction of the second connection terminal is narrower than the second connection terminal and extends linearly from the electrical component assembly. is, at least a first connection terminal of the first and second connecting terminals, the side that is convex curved when punched so as to direct the second connecting terminal side is stamped characterized Rukoto.
[0006]
According to such a configuration, the first connection terminal can be deformed by setting the width of the first connection terminal to be narrower than that of the second connection terminal , and the tolerance during assembly is absorbed by the deformation of the first connection terminal. It becomes possible to do. For this reason, it is not necessary to absorb the assembly tolerance between the components constituting the electrical component assembly, and it is not necessary to set a clearance between the components of the electrical component assembly, thereby reducing the size of the electrical component assembly. be able to. Further, the contact area of the first and second connection terminals can be made relatively small to increase the contact resistance at the time of resistance welding, so that the welding strength can be increased , and moreover from the contact resistance at the contact point of each connection terminal to the electrode. In addition, the contact resistance at the welding surface can be increased, and the welding surface can be easily heated.
[0007]
According to a second aspect of the present invention, in addition to the configuration of the first aspect of the present invention, the second connection terminal is provided with a protrusion that protrudes toward the first connection terminal over the entire width thereof. One connection terminal is projection-welded, and according to such a configuration, a tolerance shift in the width direction of the first connection terminal with respect to the second connection terminal is absorbed, and the first connection terminal is reliably brought into contact with the protruding portion. be able to. In addition, it is possible to increase the current density of the welded joint surface to make sure that the temperature of the joint surface is the peak temperature, and to perform reliable joining, and to minimize the influence of heat on the base metal by short-time welding. That is, when the protruding portion is provided in a part of the width direction of the second connection terminal, the protruding portion is softened and easily crushed by heat during welding, so that it is difficult to concentrate current, requires a large current, and protrudes. Since the amount of electrode movement increases with the softening of the part, the energization time becomes longer, and there is a possibility that the surrounding base material is affected by heat. On the other hand, when the protrusion is provided over the entire width of the second connection terminal, there are portions of the protrusion that are not in contact with the first connection terminal on both sides of the contact surface with the first connection terminal. Even if the current is concentrated, the protrusion does not soften and collapse, so that the current density on the weld joint surface can be maximized to determine the peak temperature on the weld joint surface, and the amount of electrode movement can be reduced for a short time. It becomes possible to weld.
[0008]
According to a third aspect of the present invention, in addition to the configuration of the second aspect of the invention, the protruding portion is formed in a shape that is smoothly bent toward the first connection terminal side. For example, a stress can be concentrated during projection welding so that the protruding portion does not bite into the first connection terminal side, and a good welding state can be obtained.
[0010]

The check valves 7A to 7D are connected in parallel to the normally open solenoid valves 5A to 5D so as to allow the flow of brake fluid from the corresponding wheel brakes 2A to 2D to the master cylinder M.
[0016]
The normally closed solenoid valves 6A and 6B are provided between the left front wheel brake 2A and the right rear wheel brake 2B and the first reservoir 8A. The normally closed solenoid valves 6C and 6D are the right front wheel wheels. Provided between the brake 2C and the left rear wheel brake 2D and the second reservoir 8B.

Such a brake fluid pressure control device 4 communicates between the master cylinder M and the wheel brakes 2A to 2D and between the wheel brakes 2A to 2D and the reservoirs 8A and 8B during normal braking in which each wheel is not likely to be locked. Shut off. That is, the normally open solenoid valves 5A to 5D are demagnetized and opened, and the normally closed solenoid valves 6A to 6D are demagnetized and closed, and output from the first output port 1A of the master cylinder M. The brake hydraulic pressure acts on the left front wheel brake 2A via the normally open solenoid valve 5A, and acts on the right rear wheel brake 2B via the normally open solenoid valve 5B.

[0018]
When the wheel is about to enter the locked state during the brake, the brake fluid pressure control device 4 moves between the master cylinder M and the wheel brakes 2A to 2D at a portion corresponding to the wheel about to enter the locked state.

A plurality of pairs (eight pairs in this embodiment) of second connection terminals 60 provided on the cover 16 covering the coil assemblies 35 are joined by resistance welding, for example, projection welding. As a result, the cover 16 is suspended.

[0048]
By the way, at least the first connection terminal 56 (both in this embodiment) of the first and second connection terminals 56 and 60 is made of a metal plate material 65 having conductivity, such as a copper plate, as shown in FIG. 66 and the punch 67 are formed by punching, and when the punching is completed, the surfaces of the first and second connection terminals 56 and 60 opposite to the die 66 are convex curved surfaces (so-called drooping surfaces). The first and second connection terminals 56, 60 are arranged such that the side that forms the convex curved surface is a welding surface.
[0049]
Next, the operation of the first embodiment will be described. Solenoid portions 19... 39 of the normally open solenoid valves 5A to 5D and the normally closed solenoid valves 6A to 6D are projected from the one surface 15a of the base body 15, and each solenoid is Bus bars 57, 58, 59, which are electrically connected to the solenoid parts 19, 39, 39, are embedded in the synthetic resin cover 16, which covers the parts 19, ..., 39 ... and is attached to the one surface 15a. The planar wall portion 55 is integrally provided, and the wall portion 55 is provided with a plurality of openings 53, 54, for inserting the tip ends of the solenoid portions 19,. Yes.
[0050]
Therefore, the distance from the one surface 15a of the base body 15 to the wall portion 55 is made relatively small by inserting the tips of the solenoid portions 19... 39 ... into the openings 53. The height can also be made relatively small, whereby the brake fluid pressure control device 4 can be miniaturized.
[0051]
By the way, when electrically connecting each bus bar 57 ..., 58 ..., 59 to each solenoid part 19, ..., 39 ..., it provides in the coil assembly 35 ... which comprises a part of each solenoid part 19 ..., 39 .... The pair of first connection terminals 56, 56, which are projected from the coil assemblies 35, and the second connection terminals 60, 60, which are integrally formed with the bus bars 57, 58, 59, are resistance welded. Are joined together. In addition, in a state where the first connection terminals 56, 56... Are joined to the second connection terminals 60, 60... On the cover 16 side that covers the respective coil assemblies 35. When the cover 16 is attached to the base 15, the guide cylinders 30 and 48 protruding from the one surface 15 a of the base 15 are fitted into the coil assemblies 35. It is necessary to absorb the tolerance at the time of assembly.
[0052]
Therefore, in the present invention, the width W1 of the first connection terminals 56 is set smaller than the width W2 of the second connection terminals 60. Accordingly, the first connection terminals 56 can be deformed, and the tolerance at the time of assembly can be absorbed by the deformation of the first connection terminals 56. As a result, it is not necessary to absorb assembly tolerances between the components constituting the coil assemblies 35... And it is unnecessary to set a clearance between the components of the coil assemblies 35. Can be miniaturized. In addition, when vibration is applied to the coil assemblies 35 that are suspended by the covers 16, the first connection terminals 56 that are relatively thin and weaker than the second connection terminals 60 are the coil assemblies. By being on the 35... Side, that is, on the load point side, the force acting on the first connection terminals 56. Further, the contact area of the first and second connection terminals 56, 60,... Can be made relatively small, the contact resistance during resistance welding can be increased, and the welding strength can be increased.
[0053]
The second connection terminal 60 is provided with a protrusion 60a that protrudes toward the first connection terminal 56 over the entire width thereof, and the protrusion 60a of the second connection terminal 60 and the first connection terminal 56 are projection welded. Therefore, it is possible to absorb the tolerance shift in the width direction of the first connection terminal 56 with respect to the second connection terminal 60 and to bring the first connection terminal 56 into contact with the protruding portion 60a. In addition, it is possible to increase the current density of the welded joint surface to make sure that the temperature of the joint surface is the peak temperature, and to perform reliable joining, and to minimize the influence of heat on the base metal by short-time welding. That is, when the protruding portion 60a is provided in a part of the width direction of the second connection terminal 60, the protruding portion 60a is softened and easily crushed by heat during welding, so that it is difficult to concentrate current and a large current is required. In addition, since the amount of electrode movement increases with the softening of the protrusion 60a, the energization time becomes longer, and there is a possibility that the surrounding base material is affected by heat. On the other hand, when the protrusion 60a is provided over the entire width of the second connection terminal 60, the protrusion 60a is not in contact with the first connection terminal 56 on both sides of the contact surface with the first connection terminal 56. Since there is a portion, even if the current is concentrated, the protruding portion 60a is not softened and crushed. Therefore, the current density of the weld joint surface can be maximized to determine the peak temperature on the weld joint surface, and the amount of electrode movement This makes it possible to perform welding in a short time.
[0054]
In addition, since the protrusion 60a is formed in a smoothly curved shape on the first connection terminal 56 side, stress is concentrated during projection welding so that the protrusion 60a does not bite into the first connection terminal 56 side. A good welding state can be obtained.
[0055]
Furthermore, since at least the first connection terminal 56 (both in this embodiment) of the first and second connection terminals 56 and 60 is stamped and disposed, the side that becomes a convex curved surface at the time of the punch molding is disposed as a welding surface. The contact resistance at the welding surface can be made larger than the contact resistance at the contact point of each connection terminal 56, 60 to the electrodes 63, 64, and the welding surface can be easily heated.
