Description

本発明は、レバーの回動による低挿入力でコネクタ嵌合を行うことができるレバー式コネクタに関する。 The present invention relates to a lever type connector capable of fitting a connector with a low insertion force due to rotation of the lever.

この種のレバー式コネクタとして、特許文献１に開示されたものがある。このレバー式コネクタは、カムピンを突設した雌ハウジングと、このカムピンに係合されるカム溝を有したレバーを軸ピンにより回動可能に支持する雄ハウジングと、を備えている。レバーのカム溝の左右両周面には、カムピンの入り口をなす真直面の奥側に該カムピンによって押圧可能な傾斜面（湾曲面）が設けられている。 As a lever type connector of this kind, there is one disclosed in Patent Document 1. The lever-type connector includes a female housing in which a cam pin is projected, and a male housing in which a lever having a cam groove engaged with the cam pin is rotatably supported by a shaft pin. On both the left and right peripheral surfaces of the cam groove of the lever, an inclined surface (curved surface) that can be pressed by the cam pin is provided on the back side of the face facing the entrance of the cam pin.

そして、両ハウジングを正規の仮嵌合深さまで嵌合するのに伴って、カムピンによってカム溝の傾斜面が押圧されることで、レバーに対して回動方向に沿った分力が付与され、レバーが初期位置から嵌合位置側へ回動変位する。従って、レバーの回動変位の有無に基づいて両ハウジングが正規の仮嵌合深さに達したか否かを検知することができる。 Then, as both housings are fitted to the regular temporary fitting depth, the inclined surface of the cam groove is pressed by the cam pin, so that a component force along the rotation direction is applied to the lever. The lever is rotationally displaced from the initial position to the fitting position side. Therefore, it is possible to detect whether or not both housings have reached the normal temporary fitting depth based on the presence or absence of the rotational displacement of the lever.

Then, when the male housing 11 is inserted into the hood portion 23 of the female housing 21, the convex portion 14 of the male housing 11 is housed in the recesses 23b on both sides of the flange portion 23a of the hood portion 23 of the female housing 21. It is supposed to be guided. Further, the lever 30 is rotated from the temporary locking position to the rotation completion position, and the locking projection 33 of the lever 30 is locked to the receiving portion 25b of the lock arm portion 25 of the female housing 21 to restrict rotation. Is held in. At this time, the temporary locking projection 37a of the temporary lock arm portion 37 provided on the arm portion 32 of the lever 30 is recessed from the lower edge 26a of the notch portions 26 on both sides of the hood portion 23 of the female housing 21. It is adapted to move and be accommodated in the square recess 27a of the portion 27. Further, the electric wire 50 and the female terminal 51 are sealed by a rubber stopper 52.

以上実施形態のレバー式コネクタ１によれば、図４に示すように、電線カバー４０を雌ハウジング２１に組付ける際に、電線カバー４０の係止アーム４３の係止突起４３ａが雌ハウジング２１のガイド部２２ｅに接触する。そして、図５に示すように、係止アーム４３が拡開されてスライドしながら挿入され、図８に示すように、その係止突起４３ａが係止穴２２ｆに係止される。この際、図６に示すように、係止アーム４３のテーパ面４３ｂがレバー３０のアーム部３２の切欠き部３６の切欠き面３６ａに接触し、電線カバー４０の挿入と同時にレバー３０が図６中矢印Ａ方向に回動し、レバー３０が仮係止状態となる。 According to the lever type connector 1 of the above embodiment, as shown in FIG. 4, when the electric wire cover 40 is assembled to the female housing 21, the locking projection 43a of the locking arm 43 of the electric wire cover 40 is the female housing 21. It comes into contact with the guide portion 22e. Then, as shown in FIG. 5, the locking arm 43 is expanded and inserted while sliding, and as shown in FIG. 8, the locking projection 43a is locked in the locking hole 22f. At this time, as shown in FIG. 6, the tapered surface 43b of the locking arm 43 comes into contact with the notch surface 36a of the notch 36 of the arm 32 of the lever 30, and the lever 30 is shown at the same time as the wire cover 40 is inserted. 6 Rotates in the direction of the middle arrow A, and the lever 30 is temporarily locked.

雌ハウジング２１の端子収容室２２ａに雌端子５１を挿入する作業時に、図３に示すように、レバー３０が持ち上がった状態で保持されるため、レバー３０が雌端子５１の挿入の妨げになることはなく、雌端子５１の挿入作業性を向上させることができる。 As shown in FIG. 3, when the female terminal 51 is inserted into the terminal accommodating chamber 22a of the female housing 21, the lever 30 is held in a lifted state, so that the lever 30 hinders the insertion of the female terminal 51. However, the insertion workability of the female terminal 51 can be improved.

また、図８、図９に示すように、電線カバー４０の係止アーム４３の係止突起４３ａが雌ハウジング２１の係止穴２２ｆに係止されるため、レバー３０の本係止移行時の際に電線カバー４０がレバー３０に接触することはない。つまり、カバー装着に連動したレバー３０の仮係止状態への移行の後で、雄ハウジング１１のフード部１１ａを雌ハウジング２１のフード部２３に更に押し込む。そして、雄ハウジング１１の解除部１３の先端１３ａで雌ハウジング２１の切欠き部２６の下縁２６ａと仮ロックアーム部３７の仮係止突起３７ａの仮係止状態を解除し、図９に示すように、レバー３０を矢印Ｂ方向へ回動することで、雄コネクタ１０と雌コネクタ２０の嵌合が可能となる。 Further, as shown in FIGS. 8 and 9, since the locking projection 43a of the locking arm 43 of the electric wire cover 40 is locked in the locking hole 22f of the female housing 21, the lever 30 is locked at the time of the main locking transition. At that time, the electric wire cover 40 does not come into contact with the lever 30. That is, after shifting to the temporarily locked state of the lever 30 linked to the cover attachment, the hood portion 11a of the male housing 11 is further pushed into the hood portion 23 of the female housing 21. Then, the temporary locking state of the lower edge 26a of the notch 26 of the female housing 21 and the temporary locking projection 37a of the temporary lock arm portion 37 is released by the tip 13a of the releasing portion 13 of the male housing 11, and is shown in FIG. As described above, by rotating the lever 30 in the direction of arrow B, the male connector 10 and the female connector 20 can be fitted.
