本発明は、電線付の端子を収容するコネクタハウジングと、コネクタハウジングに取り付けられて、電線を案内しつつ外部に導出させるカバーと、コネクタハウジングに回動可能に取り付けられたレバーと、を有する回動レバー式コネクタに関する。   The present invention includes a connector housing that accommodates terminals with electric wires, a cover that is attached to the connector housing and guides the electric wires to the outside, and a lever that is rotatably attached to the connector housing. The present invention relates to a moving lever type connector.

電線付の端子を収容するコネクタハウジングと、コネクタハウジングに取り付けられて、電線を案内しつつ外部に導出させるカバーと、コネクタハウジングに回動可能に取り付けられたレバーと、を有する回動レバー式コネクタが、下記特許文献１等において、知られている。   Rotating lever type connector having a connector housing that accommodates terminals with electric wires, a cover that is attached to the connector housing and guides the electric wires to the outside, and a lever that is rotatably attached to the connector housing However, it is known in Patent Document 1 below.

図８は、この種の従来の回動レバー式コネクタの部分断面図である。図９は、図８の回動レバー式コネクタの他の部分断面図である。   FIG. 8 is a partial cross-sectional view of this type of conventional rotating lever connector. FIG. 9 is another partial cross-sectional view of the rotary lever connector of FIG.

図８及び図９に示すように、この種の回動レバー式コネクタは、電線４付の端子を収容する箱型のコネクタハウジング６０と、このコネクタハウジング６０の基部側（図中、上面側）を覆うように取り付けられて、電線４を案内しつつ外部に導出させる半ドーム状のカバー７０と、コネクタハウジング６０及びカバー７０を挟み込むようにして、コネクタハウジング６０に回動可能に取り付けられたレバー８０と、を有する。複数の電線４は、図中上方向に、コネクタハウジング６０の電線キャビティ６３から出ているが、半ドーム状のカバー７０によって、図中水平方向により緩やかに湾曲されて外部に導出される。   As shown in FIGS. 8 and 9, this type of rotating lever type connector includes a box-shaped connector housing 60 that accommodates a terminal with an electric wire 4, and a base side of the connector housing 60 (upper surface side in the figure). A semi-dome-shaped cover 70 that guides the electric wire 4 and leads out to the outside, and a lever that is rotatably attached to the connector housing 60 so as to sandwich the connector housing 60 and the cover 70. 80. The plurality of electric wires 4 protrude from the electric wire cavity 63 of the connector housing 60 in the upward direction in the drawing, but are gently bent in the horizontal direction in the drawing by the semi-dome-shaped cover 70 and led out to the outside.

コネクタハウジング６０の両側面には、レバー８０の回動軸６６が設けられている。カバー７０の上部には、レバー８０の係合部８８に係止される可撓性を有するアーム状のレバー係止部７４、及びフレーム突起７２等が設けられている。レバー８０には、ガイド孔８１、回動孔８６、その他窪み８２、及び係合部８８が設けられている。レバー８０は、コネクタハウジング６０の回動軸６６に中心部が差し込まれて、この回動軸６６を中心に回動可能となる。   A rotation shaft 66 of the lever 80 is provided on both side surfaces of the connector housing 60. On the upper portion of the cover 70, a flexible arm-like lever locking portion 74 locked to the engaging portion 88 of the lever 80, a frame protrusion 72, and the like are provided. The lever 80 is provided with a guide hole 81, a rotation hole 86, other recesses 82, and an engaging portion 88. The center portion of the lever 80 is inserted into the rotation shaft 66 of the connector housing 60, and the lever 80 can rotate about the rotation shaft 66.

このような構成において、嵌合作業時には、コネクタハウジング６０には、上記基部側とは反対側（図中、下面側）には、図示しない相手コネクタが図中下方から嵌合される。このときには、相手コネクタに設けられたガイドピン（不図示）が、レバー８０のガイド孔８１にはめ込まれて、レバー８０の回動に伴ってガイドピンが上方に引き上げられて、相手コネクタがコネクタハウジング６０に嵌合される。嵌合終了後には、図８に示すように、レバー係止部７４がレバー８０の係合部８８に係止される。   In such a configuration, at the time of fitting work, a mating connector (not shown) is fitted into the connector housing 60 from the lower side in the drawing on the side opposite to the base side (the lower surface side in the drawing). At this time, a guide pin (not shown) provided on the mating connector is fitted into the guide hole 81 of the lever 80, and the guide pin is pulled upward as the lever 80 rotates, so that the mating connector is connected to the connector housing. 60. After completion of the fitting, the lever locking portion 74 is locked to the engaging portion 88 of the lever 80 as shown in FIG.

離脱作業時には、基本的に、上記と逆の作用により、コネクタハウジング６０と相手コネクタが離脱される。特に、離脱作業初期には、レバー係止部７４が図９中矢印Ｂ１に示す方向に押し下げられつつ、係合部８８が図９中矢印Ｂ２、Ｂ３に示す方向に変移されて、レバー係止部７４の係止が解除される。なお、図８、９に示すコネクタは、本発明のカバー付きコネクタの特徴をより明確に理解するために例示したものであり、特許文献１に記載のコネクタではない。
特開２００３−２７２７６８号公報 At the time of the detachment work, the connector housing 60 and the mating connector are basically detached by the reverse action. In particular, at the initial stage of the disengagement operation, the lever locking portion 74 is pushed down in the direction indicated by the arrow B1 in FIG. 9, while the engaging portion 88 is shifted in the directions indicated by the arrows B2 and B3 in FIG. The locking of the portion 74 is released. The connectors shown in FIGS. 8 and 9 are illustrated in order to more clearly understand the features of the connector with cover according to the present invention, and are not the connectors described in Patent Document 1.
JP 2003-272768 A

ところで、上述のように、離脱作業初期において、係合部８８を矢印Ｂ２、Ｂ３に示す方向に変移させるためには、レバー係止部７４を矢印Ｂ１に示す方向に十分な量だけ押し下げる必要がある。このためには、レバー係止部７４の下部に、図９でＣＬ′で示すような十分なクリアランス、すなわち、レバー係止部７４の可動スペースを確保することが必要である。   By the way, as described above, in order to shift the engaging portion 88 in the direction indicated by the arrows B2 and B3 in the initial stage of the disengaging operation, it is necessary to push down the lever locking portion 74 by a sufficient amount in the direction indicated by the arrow B1. is there. For this purpose, it is necessary to secure a sufficient clearance as shown by CL ′ in FIG. 9, that is, a movable space of the lever locking portion 74 in the lower portion of the lever locking portion 74.

しかしながら、近年、コネクタ外形の小型化が求められている。補足すると、電線４は同等でありながら、コネクタ外形の小型化が求められている。この影響により、カバー７０に対しても小型化が求められ、このため、コネクタ内において電線４の占有スペースが増大して、クリアランスＣＬ′が十分確保できない場合が発生している。   However, in recent years, there has been a demand for miniaturization of the connector outer shape. Supplementally, there is a demand for downsizing of the outer shape of the connector while the electric wires 4 are equivalent. Due to this influence, the cover 70 is also required to be miniaturized. For this reason, the occupied space of the electric wire 4 increases in the connector, and the clearance CL ′ cannot be sufficiently secured.

上記クリアランスＣＬ′が十分確保できない場合には、いうまでもなく、レバー係止部７４の可動スペースに電線４が干渉してくるので、レバー係止部７４が矢印Ｂ１に示す方向に十分な量だけ押し下げることも困難になる。この結果、係合部８８を矢印Ｂ２、Ｂ３に示す方向に変移することも困難になり、レバー係止部７４の係止解除が不可能になる。   Needless to say, when the clearance CL ′ cannot be secured sufficiently, the electric wire 4 interferes with the movable space of the lever locking portion 74, so that the lever locking portion 74 has a sufficient amount in the direction indicated by the arrow B1. It becomes difficult to push down only. As a result, it becomes difficult to shift the engaging portion 88 in the directions indicated by the arrows B2 and B3, and it becomes impossible to unlock the lever locking portion 74.

よって本発明は、上述した現状に鑑み、従来と同等の電線を用いつつコネクタ外形を小型化しても、レバー係止部の係止解除作業に支障をきたすことのない回動レバー式コネクタを提供することを課題としている。   Therefore, in view of the above-mentioned present situation, the present invention provides a rotating lever connector that does not hinder the unlocking operation of the lever locking portion even if the connector outer shape is miniaturized while using the same wire as the conventional one. The challenge is to do.

上記課題を解決するためになされた請求項１記載の回動レバー式コネクタは、電線付の端子を収容するコネクタハウジングと、前記コネクタハウジングに取り付けられて前記電線を案内するカバーと、前記コネクタハウジングに回動可能に取り付けられたレバーと、前記カバーの一部に設けられ、前記レバーの一部と係合して、可撓性を有するアーム状のレバー係止部と、を有する回動レバー式コネクタであって、前記カバーの裏面から前記電線に当接可能に突設されたリブを有して、前記電線が前記レバー係止部の可動スペースに干渉するのを抑制する、ことを特徴とする。   The rotating lever connector according to claim 1, which has been made to solve the above-described problems, includes a connector housing that accommodates terminals with electric wires, a cover that is attached to the connector housing and guides the electric wires, and the connector housing. A lever that is pivotably attached to the cover, and a lever lever engaging portion that is provided on a part of the cover and engages with a part of the lever and has flexibility. A connector that has a rib projecting from the back surface of the cover so as to come into contact with the electric wire, and prevents the electric wire from interfering with a movable space of the lever locking portion. And

請求項１記載の発明によれば、カバーの裏面から電線に当接可能に突設されたリブを有して、電線がレバー係止部の可動スペースに干渉するのを抑制する。このリブによって、たとえ、当該コネクタ内において電線の占有スペースが増大しても、レバー係止部の可動スペースは確実に確保されるので、レバー係止部の係止解除作業が妨げられることがない。したがって、従来の同等の電線を用いながらも、コネクタの小型化が可能になる。   According to the first aspect of the present invention, the rib is provided so as to protrude from the back surface of the cover so as to contact the electric wire, and the electric wire is prevented from interfering with the movable space of the lever locking portion. Even if the space occupied by the electric wire in the connector is increased by this rib, the movable space of the lever locking portion is reliably ensured, so that the unlocking operation of the lever locking portion is not hindered. . Therefore, it is possible to reduce the size of the connector while using a conventional equivalent electric wire.

上記課題を解決するためになされた請求項２記載の回動レバー式コネクタは、請求項１記載の回動レバー式コネクタにおいて、前記リブは、前記レバー係止部の自由端及び固定端側に近接して突設されている、ことを特徴とする。   The rotating lever type connector according to claim 2, which has been made to solve the above-described problem, is the rotating lever type connector according to claim 1, wherein the rib is provided on a free end and a fixed end side of the lever locking portion. It is characterized by projecting in close proximity.

請求項２記載の発明によれば、リブは、レバー係止部の自由端及び固定端側に近接して突設されている。したがって、レバー係止部の可動スペースの確保が容易になる。   According to the second aspect of the present invention, the rib protrudes close to the free end and the fixed end side of the lever locking portion. Therefore, it becomes easy to secure the movable space of the lever locking portion.

請求項１記載の発明によれば、電線がレバー係止部の可動スペースに干渉するのを抑制するために電線を上から押さえつけるように、電線押えリブがカバーの裏面から突設されている。この電線押えリブによって、たとえ、当該コネクタ内において電線の占有スペースが増大しても、レバー係止部の可動スペースは確実に確保されるので、レバー係止部の係止解除作業が妨げられることがない。したがって、従来の同等の電線を用いながらも、コネクタの小型化が可能になる。   According to the first aspect of the present invention, the wire holding rib protrudes from the back surface of the cover so as to hold down the wire from above in order to suppress the wire from interfering with the movable space of the lever locking portion. Even if the space occupied by the electric wire in the connector increases, the electric wire holding rib ensures the movable space of the lever locking portion, thereby preventing the lever locking portion from being unlocked. There is no. Therefore, it is possible to reduce the size of the connector while using a conventional equivalent electric wire.

請求項２記載の発明によれば、リブは、レバー係止部の自由端及び固定端側に近接して突設されている。このため、レバー係止部の可動スペースの確保が容易になる。したがって、従来の同等の電線を用いながらも、コネクタの小型化が可能になる。   According to the second aspect of the present invention, the rib protrudes close to the free end and the fixed end side of the lever locking portion. For this reason, it becomes easy to ensure the movable space of the lever locking portion. Therefore, it is possible to reduce the size of the connector while using a conventional equivalent electric wire.

以下、本発明の実施の形態を図面に基づいて説明する。図１は、本発明の一実施形態に係る回動レバー式コネクタを示す斜視図である。図２は、図１中のコネクタハウジングを示す斜視図である。図３は、図１中のカバーを斜め下方からみた場合の斜視図である。図４は、図１中のカバーの側面図である。図５は、図１中のカバーの背面図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a rotating lever type connector according to an embodiment of the present invention. FIG. 2 is a perspective view showing the connector housing in FIG. FIG. 3 is a perspective view when the cover in FIG. 1 is viewed obliquely from below. FIG. 4 is a side view of the cover in FIG. FIG. 5 is a rear view of the cover in FIG.

図１に示すように、この実施形態に係る回動レバー式コネクタは、電線付の端子を収容するコネクタハウジング１０、コネクタハウジング１０に取り付けられて電線を案内しつつ外部に導出させるカバー２０、及びコネクタハウジング１０に回動可能に取り付けられたレバー３０を有して構成される。コネクタハウジング１０、カバー２０及びレバー３０は共に、例えば、ＰＢＴ（ポリブチレンテレフタート）等の樹脂で構成される。   As shown in FIG. 1, a rotating lever connector according to this embodiment includes a connector housing 10 that accommodates terminals with wires, a cover 20 that is attached to the connector housing 10 and guides the wires to the outside, and The connector housing 10 is configured to have a lever 30 that is rotatably attached. The connector housing 10, the cover 20, and the lever 30 are all made of a resin such as PBT (polybutylene terephthalate).

コネクタハウジング１０には、カバー２０が図中矢印Ａ２０で示す方向から取り付けられる。また、相手コネクタ（不図示）が図中矢印Ａ１０で示す方向から嵌合されるが、このときには、相手コネクタに設けられたガイドピン（不図示）が、レバー３０のガイド孔３１にはめ込まれて、図中矢印Ａ３０方向へのレバー３０の回動に伴ってガイドピンが上方に引き上げられて、相手コネクタがコネクタハウジング１０に嵌合される。なお、この固定時における、レバー３０とカバー２０との係止に係る作用に関しては、後で、図６及び図７を用いて補足する。   A cover 20 is attached to the connector housing 10 from the direction indicated by arrow A20 in the figure. Further, the mating connector (not shown) is fitted from the direction indicated by the arrow A10 in the figure. At this time, a guide pin (not shown) provided on the mating connector is fitted into the guide hole 31 of the lever 30. As the lever 30 rotates in the direction of the arrow A30 in the figure, the guide pin is pulled upward, and the mating connector is fitted into the connector housing 10. In addition, the effect | action which concerns on the latching of the lever 30 and the cover 20 at the time of this fixation is supplemented later using FIG.6 and FIG.7.

コネクタハウジング１０は、図１及び図２に示すように、基本的に箱型をしている。その上面である基部には、電線が接続された端子が収容される円筒状の複数のキャビティ１３及び円状のキャビティ１４が設けられている。各キャビティ１３には比較的太めの電線がそれぞれ導出され、各キャビティ１４には比較的細めの電線がそれぞれ導出される。また、コネクタハウジング１０の基部周縁には、側壁１９が立設されている。側壁１９は、コネクタハウジング１０の側面に連設されているため、この側面の一部であるともいえる。互いに対向する長手方向の側壁１９には、切り欠かれてスリット１２が形成されている。   The connector housing 10 is basically box-shaped as shown in FIGS. A plurality of cylindrical cavities 13 and circular cavities 14 in which terminals to which electric wires are connected are accommodated are provided on the base, which is the upper surface. A relatively thick electric wire is led out to each cavity 13, and a relatively thin electric wire is led out to each cavity 14. A side wall 19 is erected on the peripheral edge of the base of the connector housing 10. Since the side wall 19 is connected to the side surface of the connector housing 10, it can be said that the side wall 19 is a part of this side surface. The slits 12 are formed in the side walls 19 in the longitudinal direction facing each other by being cut out.

側壁１９の長手方向のやや内側には、カバー２０側に設けられた係止突起部２１に係合するように、複数の係合部１１が立設されている。係合部１１は、外側から内側に向けて係止突起部２１を受けるような形状になっている。係合部１１の形状及び数は、係止突起部２１に対応するものである。   On the slightly inner side in the longitudinal direction of the side wall 19, a plurality of engaging portions 11 are erected so as to engage with a locking projection 21 provided on the cover 20 side. The engaging portion 11 is shaped to receive the locking projection 21 from the outside toward the inside. The shape and number of the engaging portions 11 correspond to the locking projections 21.

また、コネクタハウジング１０の両側面は、回動するレバー３０の取り付け面１５にもなっている（図１、図２では片側面のみ記載）。取り付け面１５には、レバー３０の回動軸１６及びガイド溝１８が設けられている。   Further, both side surfaces of the connector housing 10 are also mounting surfaces 15 of the lever 30 that rotates (only one side is shown in FIGS. 1 and 2). The mounting surface 15 is provided with a rotating shaft 16 and a guide groove 18 of the lever 30.

一方、カバー２０は、図１及び図３〜図５に示すように、電線が導出される電線導出部２９及び取り付け面である下面が開口した細長いドーム状をしている。カバー２０は、上記コネクタハウジング１０の側壁１９の内側に沿うようにして取り付けられるような形状になっている。カバー２０は、コネクタハウジング１０の基部側に取り付けられて、電線を案内し、電線導出部２９から外部に導出させる。   On the other hand, as shown in FIGS. 1 and 3 to 5, the cover 20 has an elongated dome shape in which a wire lead-out portion 29 from which a wire is led out and a lower surface as an attachment surface are opened. The cover 20 is shaped to be attached along the inside of the side wall 19 of the connector housing 10. The cover 20 is attached to the base side of the connector housing 10 to guide the electric wire and lead it out from the electric wire outlet 29.

カバー２０の背面には、このカバー２０をコネクタハウジング１０に固定するために、係止突起部２１が設けられている。係止突起部２１は、外側から内側に向けて係合部１１に係合するような爪状をし、対向するように２対立設されている。   A locking projection 21 is provided on the back surface of the cover 20 in order to fix the cover 20 to the connector housing 10. The locking projection 21 has a claw shape that engages with the engaging portion 11 from the outside to the inside, and is provided in two opposing positions so as to face each other.

カバー２０の両側面には、このカバー２０の図１中矢印Ａ２０で示すような取り付け方向と平行に延びるように、複数のリブ２２がそれぞれ突設されている。カバー２０の両側面にはまた、カバー２０が外側に開くことによって、係止突起部２１と係合部１１との係合具合が緩むのを防止するために、側壁１９に対向するように、カバー開き防止突部２５がそれぞれ設けられている。カバー開き防止突部２５は、電線導出部２９側に進むにつれて対向する側壁１９に徐々に近づくように傾斜している。すなわち、カバー開き防止突部２５は、電線導出部２９側を頂点とする傾斜状になっている。カバー開き防止突部２５は、電線導出部２９に近い側の対になった係止突起部２１及び係合部１１よりも電線導出部２９に近接して一対設けられている。   A plurality of ribs 22 project from both side surfaces of the cover 20 so as to extend in parallel with the mounting direction of the cover 20 as indicated by an arrow A20 in FIG. On both side surfaces of the cover 20, the cover 20 faces the side wall 19 in order to prevent the engagement state between the locking projection 21 and the engaging portion 11 from being loosened by opening outward. Cover opening prevention protrusions 25 are respectively provided. The cover opening prevention protrusion 25 is inclined so as to gradually approach the opposite side wall 19 as it proceeds toward the wire lead-out portion 29 side. That is, the cover opening prevention protrusion 25 has an inclined shape with the wire lead-out portion 29 side as a vertex. A pair of cover opening prevention protrusions 25 is provided closer to the wire lead-out portion 29 than the locking projection 21 and the engagement portion 11 that are paired on the side closer to the wire lead-out portion 29.

また、カバー開き防止突部２５に隣接して、カバー２０をコネクタハウジング１０から離脱させるための治具を挿入するための、治具挿入口２６が形成されている。この治具挿入口２６は、カバー開き防止突部２５の最低部側のカバー２０の下部が切り欠かれて形成されている。   Further, a jig insertion port 26 for inserting a jig for detaching the cover 20 from the connector housing 10 is formed adjacent to the cover opening preventing projection 25. The jig insertion port 26 is formed by notching the lower part of the cover 20 on the lowest side of the cover opening preventing projection 25.

また、カバー２０の上面には、レバー３０側に設けられた係合部３８に係止される可撓性を有するアーム状のレバー係止部２４が設けられている。このレバー係止部２４を挟むように補強部２３が立設され、レバー係止部２４の可撓性を確保するためにレバー係止部２４の一部を囲むようにコ字状のスリット２７も設けられている（図５参照）。また、レバー係止部２４の裏面には、レバー係止部２４の補強用のリブ２８も形成されている（図５参照）。カバー２０の開口した電線導出部２９に対向する側は、電線を緩やかに曲げるために、電線の剛性が考慮されて湾曲している。   Further, on the upper surface of the cover 20, there is provided a flexible arm-like lever locking portion 24 that is locked to an engagement portion 38 provided on the lever 30 side. A reinforcing portion 23 is erected so as to sandwich the lever locking portion 24, and a U-shaped slit 27 is formed so as to surround a part of the lever locking portion 24 in order to ensure flexibility of the lever locking portion 24. Is also provided (see FIG. 5). Further, a reinforcing rib 28 of the lever locking portion 24 is also formed on the back surface of the lever locking portion 24 (see FIG. 5). The side of the cover 20 facing the open wire lead-out portion 29 is curved in consideration of the rigidity of the wire in order to gently bend the wire.

更に、特に、図６に示すように、カバー２０の裏面において、レバー係止部２４の基部近傍等、すなわち、レバー係止部２４の自由端及び固定端側に近接する箇所には、電線押えリブ２９Ｌ、２９Ｌ′が、レバー係止部２４の底面２４ａよりも下方に突き出るように突設されている。電線押えリブ２９Ｌ、２９Ｌ′は、電線４の進行方向と垂直方向に延びて電線４に当接するように突設されている。電線押えリブ２９Ｌ、２９Ｌ′は、電線４がこのレバー係止部２４の可動スペースに干渉するのを抑制するために、電線４を上から押さえつけるように十分な高さを持って突設されている。電線押えリブ２９Ｌ、２９Ｌ′によって、たとえ、当該コネクタ内において電線４の占有スペースが増大しても、レバー係止部２４の可動スペースは確実に確保されるので、レバー係止部２４の係止解除作業が妨げられることがない。   In particular, as shown in FIG. 6, on the back surface of the cover 20, there is an electric wire retainer in the vicinity of the base of the lever locking portion 24, that is, in the vicinity of the free end and the fixed end side of the lever locking portion 24. The ribs 29L and 29L ′ are provided so as to protrude downward from the bottom surface 24a of the lever locking portion 24. The wire holding ribs 29L and 29L ′ are provided so as to extend in a direction perpendicular to the traveling direction of the wire 4 and to come into contact with the wire 4. The wire holding ribs 29L and 29L ′ are provided with a sufficient height so as to hold down the wire 4 from above in order to prevent the wire 4 from interfering with the movable space of the lever locking portion 24. Yes. Even if the occupied space of the electric wire 4 in the connector is increased by the electric wire holding ribs 29L and 29L ′, the movable space of the lever locking portion 24 is surely secured. Release work is not hindered.

また、コネクタハウジング１０の両取り付け面１５を両側から挟み込むように、ハウジング１０に回動可能にレバー３０が取り付けらている。レバー３０には、中心部に回動孔３６、この回動孔３６を囲むように、相手コネクタのガイドピンを案内するためのガイド孔３１、その他窪み３２が設けられている。レバー３０は、コネクタハウジング１０の回動軸１６に中心部が差し込まれて、この回動軸１６を中心に回動可能である。レバー３０には、カバー２０側に設けられたレバー係止部２４に係合する係合部３８も設けられている。   Further, a lever 30 is attached to the housing 10 so as to be rotatable so as to sandwich the two attachment surfaces 15 of the connector housing 10 from both sides. The lever 30 is provided with a rotation hole 36 at the center, a guide hole 31 for guiding the guide pin of the mating connector, and other depressions 32 so as to surround the rotation hole 36. The lever 30 is pivotable about the pivot shaft 16 with the center portion inserted into the pivot shaft 16 of the connector housing 10. The lever 30 is also provided with an engaging portion 38 that engages with the lever locking portion 24 provided on the cover 20 side.

このような構成の本回動レバー式コネクタにおける、嵌合作業時及び離脱作業時の作用について、図６及び図７を用いて説明する。図６は、実施形態の回動レバー式コネクタの部分断面図である。図７は、図６の回動レバー式コネクタの他の部分断面図である。   With reference to FIGS. 6 and 7, the operation at the time of the fitting operation and the detaching operation in the rotating lever type connector having such a configuration will be described. FIG. 6 is a partial cross-sectional view of the rotary lever connector according to the embodiment. FIG. 7 is another partial cross-sectional view of the rotary lever connector of FIG.

まず、嵌合作業時には、カバー２０が、コネクタハウジング１０の側壁１９の内側に沿うようにして、図１中矢印Ａ２０で示す方向からコネクタハウジング１０の基部に取り付けられる。このとき、カバー２０側の係止突起部２１がコネクタハウジング１０側の係合部１１に係合する。次に、相手コネクタ（不図示）が図中矢印Ａ１０で示す方向からコネクタハウジング１０の下部に嵌合される。この後、相手コネクタに設けられたガイドピン（不図示）が、レバー３０のガイド孔３１にはめ込まれて、図１中矢印Ａ３０方向へのレバー３０の回動に伴ってガイドピンが上方に引き上げられて、相手コネクタがコネクタハウジング１０に嵌合される。そして、最終的に、図６及び図７に示すように、アーム状のレバー係止部２４の可撓性を利用して、レバー係止部２４がレバー３０の係合部３８に係止されて、コネクタハウジング１０と相手コネクタとの嵌合が完了する。   First, during the fitting operation, the cover 20 is attached to the base of the connector housing 10 from the direction indicated by the arrow A20 in FIG. At this time, the locking projection 21 on the cover 20 side engages with the engagement portion 11 on the connector housing 10 side. Next, a mating connector (not shown) is fitted to the lower part of the connector housing 10 from the direction indicated by the arrow A10 in the drawing. Thereafter, a guide pin (not shown) provided on the mating connector is fitted into the guide hole 31 of the lever 30, and the guide pin is pulled upward as the lever 30 rotates in the direction of arrow A30 in FIG. Then, the mating connector is fitted into the connector housing 10. Finally, as shown in FIGS. 6 and 7, the lever locking portion 24 is locked to the engaging portion 38 of the lever 30 using the flexibility of the arm-shaped lever locking portion 24. Thus, the fitting between the connector housing 10 and the mating connector is completed.

これに対して、離脱作業は、レバー係止部２４を図７中の矢印Ａ１の方向へ押すことにより、レバー３０の係合部３８との係合を解除する。次に、レバー３０を、反矢印Ａ３０方向へ回動させることにより、コネクタハウジング１０と相手コネクタが離脱される。なお、レバー係止部２４を押す際、レバー係止部２４の下面と電線４との間には、電線押えリブ２９Ｌ、２９Ｌ′により、クリアランスＣＬが確保されているため、レバー係止部２４と電線との干渉を防止し、離脱作業が容易に行われる。   On the other hand, in the disengagement operation, the lever locking portion 24 is pushed in the direction of arrow A1 in FIG. Next, the connector housing 10 and the mating connector are detached by rotating the lever 30 in the direction of the arrow A30. When the lever locking portion 24 is pushed, the clearance CL is secured between the lower surface of the lever locking portion 24 and the electric wire 4 by the wire holding ribs 29L and 29L ′. And the wire are prevented from interfering with each other.

以上説明したように、本発明の実施形態によれば、カバー２０の裏面から突設された電線押えリブ２９Ｌ、２９Ｌ′によって、たとえ、当該コネクタ内において電線の占有スペースが増大しても、レバー係止部２４の可動スペースは確実に確保されるので、レバー係止部２４の係止解除作業が妨げられることがない。したがって、従来の同等の電線を用いながらも、コネクタの小型化が可能になる。   As described above, according to the embodiment of the present invention, even if the occupied space of the electric wire in the connector is increased by the electric wire holding ribs 29L and 29L ′ protruding from the back surface of the cover 20, the lever Since the movable space of the locking portion 24 is ensured, the unlocking operation of the lever locking portion 24 is not hindered. Therefore, it is possible to reduce the size of the connector while using a conventional equivalent electric wire.
