図3は、実施例1及び実施例2に対応し、図1のパネル回路基板1のイジェクタ側からの側面図で、枠体4、パネル7、略直方体のブロック8、及び、コネクタ本体3の基部14の各々の接続構成を示している。
図7は、図3における略直方体のブロック8に接続されるネジ11及びネジ24の螺合挿入された詳細な状態を示す拡大側面図である。
パネル回路基板1は、回路基板5と、回路基板5の回路配線(図示されていない)に接続された電気端子2を収容するコネクタ本体3と、ユニット配線ラックの挿入口を封鎖するためのパネル7と、パネル7に取付けられた導電性の枠体4と、回動することによってパネル回路基板1をユニット配線ラックから取り出すことができるイジェクタ6と、略直方体のブロック8とを具備している。
また、枠体4は、ネジ11によってパネル7及びコネクタ本体3の基部14とともに貫通されるタブ32を備える。さらに、枠体4は、コネクタ本体3の収容部13を挿通可能な開口部17を有しており、パネル回路基板1の組立の際に、収容部13は開口部17から挿入されて、枠体4の枠内にて収容部13の少なくとも一部が覆われる。
さらに、枠体4は、その開口部17の縁部から突出した爪部15を有しており、その爪部15が、コネクタ本体3の収容部13と枠体4との間の隙間に挿入されるようにパネルの開口部の縁部近傍で圧入固定されることにより、パネル回路基板1の組立前に予め枠体4とパネル7とを固定できる。
ネジ11は、枠体4のタブ32に形成された貫通孔33、パネル7に形成された貫通孔34、及び、コネクタ本体3の基部14に形成された貫通孔35を挿通し、略直方体のブロック8の面30内に形成されたネジ切り孔31内に螺合挿入されて、枠体4、パネル7、及びコネクタ本体3の基部14を固定する。
ネジ24は、上述の通り、回路基板5及びコネクタ本体3の基部14を挿通し、略直方体のブロック8の面36内に形成されたネジ切り孔39内に螺合挿入されて、回路基板5及びコネクタ本体3の基部14を固定する。
よって、略直方体のブロック8は、ネジ24とネジ11によって2箇所で所定の構成部品を固定する機能を有する。
なお、ネジ24’は、イジェクタ6の取付け側と反対の回路基板5の端縁部近傍において、コネクタ本体3の基部14と回路基板5とにそれぞれ設けられた孔を貫通してナット等によって螺合接続される。
図11では、2つの取り付けブロック511と525が設けられているのに対し、図12では、単一ブロック8のみで構成され、図11に示す取り付けブロック511が省略されている。図12では、その省略されて空いたスペースを利用して、電気端子2が配列方向に多く確保されていることがわかる。
図8は図4の斜線部28に接続されるネジ11及びネジ24の螺合挿入された詳細な状態を示す拡大側面図である。
図9は図5の斜線部27に接続されるネジ24の螺合挿入された詳細な状態を示す拡大側面図である。
また、一体部分27が導電性部材でなくても、略直方体のブロック8、パネル7、枠体のうち2つ、及び、ネジ11が不要となるため、パネル回路基板1の組立部品数を削減できて組立構成が容易なコネクタを提供できる効果を得ることができる。
実施例5でも、実施例1と同様に、回路基板5は、一体部分29の底面36内にネジ切った孔39にネジ24で固定され、枠体4及びパネル7は、一体部分29の側面内にネジ切った孔31にネジ11で固定されるので、一体部分29は2箇所で各構成部品を固定する機能を有する。
本発明の実施例1のパネル回路基板1に実装されるコネクタは、コネクタ本体3の基部14と回路基板5とをイジェクタ6の回動軸部によって固定する構成としたので、規格化された小型回路基板の小スペースの縁部にコネクタ部を取付けることができ、その結果、コネクタの電気端子数を多く確保させる等の複雑な回路構成に適応できる効果を奏する。
