図５は、実開昭５５−３６５２９号や特願平４−２２５８０８号等に開示され ている従来のコネクタを示す縦断面図である。 該コネクタ２５は、コネクタハウジング２６の外壁に、取付パネル２７に対す る一対の可撓係止アーム２８を設け、該コネクタハウジング２６の内側に端子２ ９を係止ランス３０で一次係止させると共に、該ハウジング２６の後部開口から 合成樹脂製のリヤホルダ３１を挿着して、該リヤホルダ３１の先端３１ａで該端 子２９の後段部２９ａを二重係止させるものである。該リヤホルダ３１は係止突 起３２をコネクタハウジング２６の係合窓３３に係合させることにより係止され る。 FIG. 5 is a longitudinal sectional view showing a conventional connector disclosed in Japanese Utility Model Publication No. 55-36529, Japanese Patent Application No. 4-225808 and the like. The connector 25 is provided with a pair of flexible locking arms 28 against the mounting panel 27 on the outer wall of the connector housing 26, and the terminal 29 is primarily locked inside the connector housing 26 with a locking lance 30. A rear holder 31 made of synthetic resin is inserted from the rear opening of the housing 26, and the rear end portion 29a of the terminal 29 is doubly locked by the tip 31a of the rear holder 31. The rear holder 31 is locked by engaging the locking protrusion 32 with the engagement window 33 of the connector housing 26.
【０００３】 しかしながら、上記従来のコネクタ２５にあっては、例えば端子２９′の挿入 が不完全な場合にリヤホルダ３１の挿着も不完全になり、作業者がその異常に気 づかずにそのまま取付パネル２７に組み付けてしまうことがあった。その場合に は使用中にリヤホルダ３１の脱落や端子２９の抜けを生じて導通不良を起こすと いう不具合を生じた。However, in the above-mentioned conventional connector 25, for example, when the insertion of the terminal 29 ′ is incomplete, the rear holder 31 is also incompletely attached, and the operator attaches it as it is without noticing the abnormality. It was sometimes assembled on the panel 27. In that case, there was a problem that the rear holder 31 came off and the terminal 29 came off during use, resulting in poor conduction.
【０００４】[0004]
本考案は、上記した点に鑑み、端子の不完全挿入等に起因するリヤホルダの不 完全挿着を確実に防止し得るリヤホルダ不完全挿着防止コネクタを提供すること を目的とする。 In view of the above points, an object of the present invention is to provide a rear holder incomplete insertion preventing connector capable of reliably preventing incomplete insertion of the rear holder due to incomplete insertion of terminals and the like.

【課題を解決するための手段】 上記目的を達成するために、本考案は、嵌合固定用の可撓係止アームを有する コネクタハウジングに、該コネクタハウジングに対する仮係止部と本係止部とを 有する端子係止用リヤホルダを挿着させるコネクタにおいて、該コネクタハウジ ングに該仮係止部を係合させた状態で該可撓係止アームの撓み空間内に位置して 該可撓係止アームの撓みを防止する撓み防止突起を該リヤホルダに設けたことを 特徴とする。In order to achieve the above object, the present invention provides a connector housing having a flexible locking arm for fitting and fixing, and a temporary locking part and a main locking part for the connector housing. In a connector into which a terminal locking rear holder having is inserted, the flexible housing is positioned within the bending space of the flexible locking arm with the temporary locking portion engaged with the connector housing. The rear holder is provided with a deflection preventing projection for preventing the stop arm from deflecting.
【０００６】[0006]
リヤホルダの本係止に移行するまでの仮係止状態においてコネクタを取付パネ ルや相手コネクタに嵌合させようとしても、リヤホルダの撓み防止突起が可撓係 止アームの撓みを阻止するから、コネクタの嵌合を行うことができない。それに よりリヤホルダの不完全挿着が検知される。 Even if you try to fit the connector to the mounting panel or the mating connector in the temporarily locked state until the rear holder is fully locked, the bending prevention protrusion of the rear holder prevents the flexible locking arm from bending. Cannot be fitted. As a result, incomplete insertion of the rear holder is detected.

図１は、本考案に係るリヤホルダ不完全挿着防止コネクタの一実施例を示す分 解斜視図、図２〜４は同じく横断面図である。 該リヤホルダ不完全挿着防止コネクタ１は、従来同様に両外側壁２に取付パネ ル３（図３）に対する一対の可撓係止アーム４を設けた合成樹脂製のコネクタハ ウジング５と、該コネクタハウジング５内に後方から挿着される合成樹脂製のリ ヤホルダ６と、該コネクタハウジング５の端子収容室７に挿入される端子８（図 ４）とにより構成される。そして該リヤホルダ６の直立した両側壁９に、該コネ クタハウジング５の可撓係止アーム４の撓み空間１０内に臨む撓み防止突起１１ を設けたことを特徴とする。 FIG. 1 is a disassembled perspective view showing an embodiment of a rear holder incomplete insertion prevention connector according to the present invention, and FIGS. The rear holder incomplete insertion prevention connector 1 includes a connector housing 5 made of a synthetic resin in which a pair of flexible locking arms 4 for mounting panels 3 (FIG. 3) are provided on both outer side walls 2 as in the conventional case, and the connector. The rear holder 6 is made of synthetic resin and is inserted into the housing 5 from the rear, and the terminals 8 (FIG. 4) are inserted into the terminal accommodating chamber 7 of the connector housing 5. The upright side walls 9 of the rear holder 6 are provided with anti-bending projections 11 facing the flexible space 10 of the flexible locking arm 4 of the connector housing 5.
【０００８】 該撓み防止突起１１はリヤホルダ側壁９の外側面のほぼ中央に各一対設けられ る。該コネクタハウジング５の側壁２の後端方には可撓係止アーム４の撓み空間 としての切欠開口１２を設けてあり、該開口１２に対向してリヤホルダ側壁９を 位置させることにより、撓み防止突起１１が該開口１２内に位置して可撓係止ア ーム４の裏面に対向する。A pair of the anti-bending projections 11 are provided at substantially the center of the outer surface of the rear holder side wall 9. At the rear end of the side wall 2 of the connector housing 5, there is provided a cutout opening 12 as a bending space of the flexible locking arm 4, and by bending the rear holder side wall 9 so as to face the opening 12, it is possible to prevent bending. The protrusion 11 is located in the opening 12 and faces the back surface of the flexible locking arm 4.
【０００９】 該ハウジング側壁２の中間部から前端方にかけては該開口１２との間に隔壁部 １３をはさんでリヤホルダ６に対する仮係止用の係合窓１４を設け、該係合窓１ ４の内側にハウジング後端からリヤホルダ側壁９に対する挿通溝１５を設けてい る。From the middle portion of the housing side wall 2 toward the front end, an engaging window 14 for temporarily retaining the rear holder 6 is provided between the opening 12 and the partition wall 13 and the engaging window 14 is provided. An insertion groove 15 from the rear end of the housing to the rear holder side wall 9 is provided inside.
【００１０】 該リヤホルダ側壁９の前端部には該係合窓１４に対する仮係止突起１６を設け てあり、リヤホルダ側壁９と直交して水平方向に連成された櫛歯状の端子係止板 １７の基部には、該コネクタハウジング５の上下の膨出フード部１８に形成され た係合溝１９に対する本係止突起２０を設けている。該端子係止板１７はフード 部１８内に挿入され、先端で端子８の後段部８ａを係止する。該リヤホルダ側壁 ９の後端にはフード後端部に対する停止突部２１を設けている。A provisional locking projection 16 for the engagement window 14 is provided at the front end of the rear holder side wall 9, and a comb-teeth-shaped terminal locking plate is formed horizontally and orthogonal to the rear holder side wall 9. The base of 17 is provided with a main locking protrusion 20 for an engagement groove 19 formed in the upper and lower bulged hood portions 18 of the connector housing 5. The terminal locking plate 17 is inserted into the hood portion 18 and locks the rear portion 8a of the terminal 8 at the tip. At the rear end of the rear holder side wall 9, a stop projection 21 for the rear end of the hood is provided.
【００１１】 そして図２の如くリヤホルダ６をコネクタハウジング５に挿入し、仮係止突起 １６をハウジング側壁２の係合窓１４に係止させる。この仮係止状態においてリ ヤホルダ６の撓み防止突起１１はハウジング５の可撓係止アーム４の後端部寄り に対向して位置する。そのため図３の如くリヤホルダ６が仮係止（不完全挿着） の状態でコネクタハウジング５を取付パネル３に嵌合させようとしても、可撓係 止アーム４が撓み防止突起１１に突き当たりそれ以上撓むことができず、それに よりコネクタハウジング５の嵌合が阻止される。リヤホルダ６の仮係止状態は端 子８の不完全挿入によっても引き起こされ、リヤホルダ６の挿着不完全の検知に より端子６の挿入不良も発見できる。Then, as shown in FIG. 2, the rear holder 6 is inserted into the connector housing 5, and the temporary locking projection 16 is locked to the engagement window 14 of the housing side wall 2. In this temporarily locked state, the flexure prevention projections 11 of the rear holder 6 are positioned to face the rear end portion of the flexible locking arm 4 of the housing 5. Therefore, even if the connector housing 5 is fitted to the mounting panel 3 with the rear holder 6 temporarily locked (incompletely inserted) as shown in FIG. It cannot be bent, which prevents the connector housing 5 from being fitted. The provisionally locked state of the rear holder 6 is also caused by the incomplete insertion of the terminal 8, and the defective insertion of the terminal 6 can be found by detecting the incomplete insertion of the rear holder 6.
【００１２】 リヤホルダ６における撓み防止突起１１の位置と高さは、仮係止突起１６が隔 壁部１３を離れて本係止突起２０が係合溝１９に係入する間において、すなわち 図４の本係止状態に移行するまでの間において可撓係止アーム４に干渉するよう に設定される。リヤホルダ６の本係止状態で撓み防止突起１１はハウジング５の 隔壁部１３に接して可撓係止アーム４の撓みを許容する。また端子８はリヤホル ダ６の仮係止状態でハウジング５内に挿入され、本係止状態で端子係止板１７の 先端部１７ａとハウジング５の係止ランス２２（図３）とにより二重係止される 。The position and height of the bending prevention protrusion 11 in the rear holder 6 are determined while the temporary locking protrusion 16 leaves the partition wall 13 and the main locking protrusion 20 engages with the engagement groove 19, that is, as shown in FIG. It is set so as to interfere with the flexible locking arm 4 before the shift to the main locking state. When the rear holder 6 is in the fully locked state, the bending prevention protrusion 11 contacts the partition wall portion 13 of the housing 5 to allow the bending of the flexible locking arm 4. The terminal 8 is inserted into the housing 5 with the rear holder 6 temporarily locked, and in the fully locked state, the terminal 8 is doubled by the tip 17a of the terminal locking plate 17 and the locking lance 22 (FIG. 3) of the housing 5. Be locked.
【００１３】[0013]
以上の如くに、本考案によれば、リヤホルダの不完全挿着状態において撓み防 止突起がコネクタハウジングの可撓係止アームの撓みを阻止するから、コネクタ 自体を取付パネルや相手コネクタに嵌合させることができず、これによりリヤホ ルダの不完全挿入が検知され、端子の挿入不良も合わせて確認される。それによ り使用中のリヤホルダの脱落や端子の抜けによる導通不良等が未然に防止される 。 As described above, according to the present invention, when the rear holder is incompletely inserted, the bending prevention projections prevent the flexible locking arm of the connector housing from bending, so that the connector itself is fitted to the mounting panel or the mating connector. As a result, incomplete insertion of the rear holder is detected, and defective insertion of terminals is also confirmed. As a result, it is possible to prevent the rear holder from falling off during use, and poor continuity due to the terminals coming off.
