Abstract
Description
一方、電波暗室など遮へいされた閉鎖空間の外と内を複数の信号ケーブル等により接続するために、遮へい用の壁面等の外と内を遮蔽する構造体に複数のコネクタを個々に装着するのではなく、構造体に開口部を設け、構造体の開口部に複数のコネクタを有するコネクタパネルを装着することにより、遮蔽性(シールド性能)を担保して、構造体の内外を複数の信号ケーブル等により接続することが考えられている。
すなわち、コネクタパネルを構造体の開口部に装着した場合に遮蔽性を担保し、かつ、複数のコネクタに接続されるケーブル類のメンテナンスを行う場合に、コネクタパネルを構造体から取り外す作業、及び取り外したコネクタパネルを構造体に装着する作業が容易に行うことができることが望まれる。
実施の形態1に係るコネクタパネルを図1から図7に基づいて説明する。
コネクタパネルは、図1及び図2に示すように、パネル基体1と装着体2と中間保持体3と複数のコネクタ4を備える。
電波暗室を構成する壁の裏面に電波吸収体が装着されている。
第1のねじ部1aは雄の平行ねじである。
パネル基体1は、表面側である一面側に一方の端部が突出し、裏面側である他面側に他方の端部が突出した複数のコネクタ4が装着される。
また、図示はしていないが、パネル基体1の表面側と裏面側とを貫通する貫通管など電波暗室の内外を接続するポートがパネル基体1に実装される。
また、複数のコネクタ4それぞれは、一方の端部に設けられた第1の端子に信号ケーブル等の第1のハーネスケーブル(図示せず)が接続され、他方の端部に設けられた第2の端子に信号ケーブル等の第2のハーネスケーブル(図示せず)が接続される。
コネクタ4の数は、一例として4個としているが、4個に限るものではない。
第1の円筒部2aは、構造体の内側から構造体に設けられた開口部に外周面が密着されて挿入される。
第1のフランジ2bは、周辺に沿って等間隔に複数のねじ用貫通孔2cが形成され、構造体に設けられた開口部の縁部、つまり、構造体である壁に設けられた開口部の内面側の縁部に、ねじ用貫通孔2cを貫通したねじにより多点で固定される。
例えば、装着体2の構造体への装着は、第1の円筒部2aの内径が構造体に設けられた開口部の内径と同じにして、第1の円筒部2aが開口部と連通して構造体の外側に配置され、第1のフランジ2bが開口部の外面側の縁部に固定されるものでもよい。
第2のねじ部2dは雌の平行ねじである。
中間保持体3は、パネル基体1と装着体2との間に、パネル基体1及び装着体2それぞれと螺合されてパネル基体1を装着体2に取り付ける。中間保持体3は導電性部材であり、装着体2により接地され、パネル基体1を接地させる。その結果、パネル基体1と装着体2と中間保持体3は電気的に接続されて接地されるため、シールド性能を満足する。
第3のねじ部3cはパネル基体1の第1のねじ部1aと同じねじサイズである。
第4のねじ部3eは、図5に示すように、雄の平行ねじ3e1と平行ねじ3e1に連続する雄のテーパねじ3e2を有する雄ねじである。
各スリット3dは、第2の円筒部3aの他端面から、つまり、第4のねじ部3eの始端から終端までの連続した第2の円筒部3aに、第2の円筒部3aの外面から内面まで貫通して形成されたスリットである。
テーパねじ3e2は、ねじ山の終わり部分、つまり、平行ねじ3e1の終端から連続して第2の円筒部3aの一端までの部分に形成され、ねじの終端、つまり、第2のフランジ部3bに向かって外径が大きくなる。要するに、テーパねじ3e2は、平行ねじ3e1のサイズより徐々にねじの終端に向かって外径が大きくなるテーパ構造である。
まず、装着体2を壁に設けられた開口部に固定する。
すなわち、装着体2の第1の円筒部2aを、壁の内側から開口部に外周面を密着させて挿入し、第1のフランジ2bを、開口部の縁部である壁の内面に、ねじをねじ用貫通孔2cに貫通させてねじ止めして固定する。
すると、第4のねじ部3eの平行ねじ3e1が第2のねじ部2dに螺合し、右ねじの構造であるため、中間保持体3が図示X方向に進み、中間保持体3が装着体2に仮装着される。
図6には図示していないが、パネル基体1に装着された複数のコネクタ4それぞれには、他方の端部に設けられた第2の端子に第2のハーネスケーブルが接続されている。
また、パネル基体1の他端側である裏面側に、構造体である壁の面に設けられている電波吸収体と同じものが装着されている。
パネル基体1の装着に際してパネル基体1を回転させないので、複数のコネクタ4それぞれに接続された第2のハーネスケーブルが捻じられることはない。
この状態を図7に示す。
図7に示されるように、パネル基体1の一端面である表面が中間保持体3の第2のフランジ部3bの一端面と面一にされ、中間保持体3における第4のねじ部3eの平行ねじ3e1に連続したテーパねじ3e2の一部が装着体2の第2のねじ部2dに螺合される。また、中間保持体3の第2のフランジ部3bの他端側の面が構造体である壁の裏面と面一にされる。
装着体2の第1のフランジ2bと中間保持体3の第2のフランジ部3bとにより、壁の両面に密着して壁を挟持するため、シールド性能が高い。
従って、中間保持体3のみを回転させることにより、パネル基体1が中間保持体3を介して装着体2に取り付けられるため、取り付け作業が容易である。
その結果、テーパねじ3e2が形成された中間保持体3の部分が、中間保持体3における第4のねじ部3eが形成された第2の円筒部3aの部分に形成された複数のスリット3dにより、図示矢印Y方向に弾性変形し、中間保持体3は装着体2に強固に密着される。
導電性部材で構成されたパネル基体1と装着体2と中間保持体3によるシールド性能が、装着体2と中間保持体3との間、及び中間保持体3とパネル基体1の間が強固に密着されるため、さらにシールド性能が向上する。
パネル基体1の装着体2からの取り外し方は、基本的には、上記で説明した装着体2へのパネル基体1の取り付け方と逆になる。
パネル基体1の一端側である表面は露出された面になっているため、第1のハーネスケーブルのコネクタ4の第1の端子からの取り外しは容易である。
第1のハーネスケーブルの必要最小限の取り外しでも、後の作業に支障をきたすことはない。
すると、図7に示す状態から、パネル基体1が図示矢印X方向とは逆方向に進み、同時に、中間保持体3が図示X方向とは逆方向に進む。
従って、第2のハーネスケーブルのコネクタ4の第2の端子からの取り外しが可能になり、第2のハーネスケーブル及び複数のコネクタ4のメンテナンス作業が行える。
中間保持体3は、装着体2に仮装着されたままでもよく、また、中間保持体3を反時計廻りに回転させて装着体2から取り外してもよい。
中間保持体3における第4のねじ部3eとして、ねじ山の始まり部分が雄の平行ねじ3e1であり、ねじ山の終わり部分が終端に向かって大きくなる雄のテーパねじ3e2としたので、テーパねじ3e2により、第2のねじ部2dと第4のねじ部3eとの密着性及び第1のねじ部1aと第3のねじ部3cの密着性が高まり、シールド性能が良くなる。
さらに、第4のねじ部3eが形成された第2の円筒部3aの部分にスリット3dを複数設けることにより、テーパねじ3e2が弾性変形するため、さらにシールド性能が向上する。
実施の形態2に係るコネクタパネルを図8に基づいて説明する。
実施の形態2に係るコネクタパネルは、実施の形態1に係るコネクタパネルが、パネル基体1における第1のねじ部1aと中間保持体3における第3のねじ部3cの螺合が装着体2における第2のねじ部2dと中間保持体3における第4のねじ部3eの螺合と逆向きであるのに対して同じ向き、つまり、左ねじか右ねじの一方のねじ構造にした点が異なり、その他の点は同じである。
なお、図8中、図1から図7に示した符号と同一符号は同一又は相当部分を示す。
まず、装着体2を構造体である壁に設けられた開口部に固定する。固定の仕方は、実施の形態1に係るコネクタパネルと同じである。
この時、パネル基体1は回転させず、中間保持体3のみを時計廻りに回転させる。第1のねじ部1aが第3のねじ部3cに螺合し、右ねじの構造であるため、パネル基体1が図示Z方向に進み、パネル基体1が中間保持体3に仮装着される。
すると、第4のねじ部3eの平行ねじ3e1が第2のねじ部2dに螺合し、右ねじの構造であるため、中間保持体3が図示Z方向とは逆のX方向に進み、中間保持体3が装着体2に装着され、同時に、パネル基体1が図示Z方向に進み、パネル基体1が中間保持体3に装着される。
従って、中間保持体3のみを回転させることにより、パネル基体1が中間保持体3を介して装着体2に取り付けられ、取り付け作業が容易である。
取り付け作業中、パネル基体1は回転させず、中間保持体3のみを時計廻りに回転させるだけであるので、第2のハーネスケーブルが捻じられることはない。
次に、パネル基体1は回転させず、中間保持体3のみを、取り付け時とは逆回転である反時計廻りに回転させる。
中間保持体3の第4のねじ部3eが装着体2の第2のねじ部2dとの螺合が解かれ、中間保持体3が装着体2から取り外せ、その後、パネル基体1の第1のねじ部1aが第3のねじ部3cとの螺合が解かれ、パネル基体1は中間保持体3から取り外せる。
実施の形態2に係るコネクタパネルは、実施の形態1に係るコネクタパネルと同様の効果を奏する。
実施の形態3に係るコネクタパネルを図9から図12に基づいて説明する。

第3のねじ部3cは、図11に示すように、雌のテーパねじ3c1とテーパねじ3c1に連続する雌の平行ねじ3c2を有する雌ねじである。
テーパねじ3c1の終端は、第2の円筒部3aの一端より他端側に位置する。
中間保持体3は、特に、図11に実線により示すように、第4のねじ部3eが形成された第2の円筒部3aの部分に、第2の円筒部3aの中心軸に平行なスリット3dを円周方向に沿って等間隔に複数有する。
つまり、第2の円筒部3aに位置する第3のねじ部3cの部分にスリット3dが形成される。
第4のねじ部3eは、雄の平行ねじである。第4のねじ部3eは、装着体2の第2のねじ部2dと同じねじサイズである。
この仮装着した状態で、中間保持体3の他端側の開口端と装着体2の一端側の開放端とを中心軸を一致させて対向させ、中間保持体3の第4のねじ部3eを装着体2の第2のねじ部2dに押し当て、中間保持体3を時計廻りに回転させる。
この状態でメンテナンス作業等の作業を行ってもよい。
さらに、中間保持体3を反時計方向に回転させると、パネル基体1を中間保持体3から取り外せる。
実施の形態3に係るコネクタパネルは、実施の形態1に係るコネクタパネルと同様の効果を奏する。
実施の形態4に係るコネクタパネルを図13に基づいて説明する。
実施の形態4に係るコネクタパネルは、装着体2の第2のねじ部2dと中間保持体30の第4のねじ部3eのねじ構造が実施の形態1に係るコネクタパネルにおける装着体2の第2のねじ部2dと中間保持体30の第4のねじ部3eのねじ構造と異なり、その他の点は同じである。
なお、図13中、図1から図7に示した符号と同一符号は同一又は相当部分を示す。
この仮装着した状態で、中間保持体3の他端側の開口端と装着体2の一端側の開放端とを中心軸を一致させて対向させ、中間保持体3の第4のねじ部3eを装着体2の第2のねじ部2dに押し当て、中間保持体3を時計廻りに回転させる。
この状態でメンテナンス作業等の作業を行ってもよい。
さらに、中間保持体3を反時計方向に回転させると、パネル基体1を中間保持体3から取り外せる。
実施の形態4に係るコネクタパネルは、実施の形態1に係るコネクタパネルと同様の効果を奏する。
実施の形態5に係るコネクタパネルを図14及び図15に基づいて説明する。
実施の形態5に係るコネクタパネルは、実施の形態1に係るコネクタパネルにおける装着体2の第2のねじ部2dが第1のフランジ2bと反対側に位置する第1の円筒部2aの内周面の一端部に形成されているのに対し、第2のねじ部2d及び第1のフランジ2bが第1の円筒部2aの一端に位置する点が異なり、その他の点は同じである。
なお、図14及び図15中、図1から図7に示した符号と同一符号は同一又は相当部分を示す。
パネル基体1及び中間保持体3は、装着体2の第1のフランジ2bが位置する一端側から、実施の形態1に係るコネクタパネルと同様に装着される。
