産業上の利用分野
本発明は一対のコネクタハウジングの嵌合操作
時において表示機構により過不足のない適切な嵌
合状態を外部から確認し得るようにしたものであ
る。[Detailed Description of the Invention] [Objective of the Invention] Industrial Field of Use The present invention provides a display mechanism for externally confirming the proper mating state without excess or deficiency during the mating operation of a pair of connector housings. This is what I did.
従来の技術
嵌合荷重の比較的に小さいコネクタハウジング
にあつては、雌，雄のコネクタハウジングの嵌合
操作の終了は相互の衝合時における手の感触によ
つて充分に知ることが出来るが、嵌合荷重の大き
い場合やねじ締め型のコネクタハウジングの場合
には衝合感覚がないので、嵌合の完了を確認する
ことができない。Prior Art In the case of connector housings with a relatively small mating load, the completion of the mating operation of the female and male connector housings can be sufficiently determined by the feel of the hand when they collide with each other. If the fitting load is large or if the connector housing is of a screw-tight type, there is no sense of contact, so it is not possible to confirm the completion of fitting.
そして、この場合には両コネクタハウジングに
おける端子金具の挿入力が大きい場合には、嵌合
操作の途中で嵌合終了と感違いをして中途半端な
位置で放置することがあり、他方ではねじの締め
付け等によりコネクタハウジング等を破壊するお
それもある。 In this case, if the insertion force of the terminal fittings in both connector housings is large, it is possible to mistakenly think that mating is complete during the mating operation and leave it in a halfway position. There is also a risk of damaging the connector housing etc. due to tightening.
