図４は、実開昭６２−１３８２号公報に記載された従来の端子係止コネクタを 示すものである。 該コネクタ３１は、左右の端子収容室３２，３２間の隔壁３３に一対の可撓係 止片３４，３４を対称に設け、該係止片３４に対向する収容室内壁３５に、端子 ３６の後段部３７に対する係止突部３８を設けて成るコネクタハウジング３９と 、該一対の可撓係止片３４，３４の間に挿入されるクサビ状のスペーサ４０とに より構成される。 FIG. 4 shows a conventional terminal locking connector disclosed in Japanese Utility Model Laid-Open No. 62-1382. In the connector 31, a pair of flexible locking pieces 34, 34 are symmetrically provided on a partition wall 33 between the left and right terminal receiving chambers 32, 32, and a terminal 36 is provided on a wall 35 of the receiving chamber facing the locking piece 34. It is composed of a connector housing 39 provided with a locking projection 38 for the rear stage 37 and a wedge-shaped spacer 40 inserted between the pair of flexible locking pieces 34, 34.
【０００３】 該端子３６は可撓係止片３４を撓ませて収容室３２内に挿入され、後段部３７ を係止突部３８に乗り越し係合させる。その状態でスペーサ４０を可撓係止片３ ４，３４の間に挿入させることにより、該係止片３４が外側に押圧されて端子３ ６の後段部３７を係止突部３８に係止させる。The terminal 36 bends the flexible locking piece 34 and is inserted into the accommodating chamber 32, and the rear step portion 37 rides over the locking projection portion 38 and engages with it. By inserting the spacer 40 between the flexible locking pieces 34 and 34 in this state, the locking piece 34 is pressed outward and the rear stage 37 of the terminal 36 is locked to the locking projection 38. Let
【０００４】 しかしながら、上記従来の構造にあっては、端子３６を可撓係止片３４と係止 突部３８との間に挿通させる関係上、該係止突部３８の突出高さをあまり大きく できず、そのために端子後抜き方向の係止力に限界があった。また、端子半挿入 の場合にスペーサ４０を係止片３４，３４の間に無理やり押し込むことも可能で あり、端子３６の不完全挿入に対する検知性が弱いという問題もあった。However, in the above-described conventional structure, since the terminal 36 is inserted between the flexible locking piece 34 and the locking projection 38, the projection height of the locking projection 38 is too small. Since it could not be increased, there was a limit to the locking force in the terminal rear pulling direction. Further, when the terminal is half inserted, it is possible to force the spacer 40 to be pushed between the locking pieces 34, 34, and there is also a problem that the detectability for incomplete insertion of the terminal 36 is weak.
【０００５】[0005]
本考案は、上記した点に鑑み、端子の後抜き方向の係止力を増大させると共に 、端子の不完全挿入を防止し得る端子係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 terminal locking connector capable of increasing the locking force in the rearward pulling direction of the terminal and preventing incomplete insertion of the terminal.
【０００６】[0006]
上記目的を達成するために、本考案は、端子挿入方向と直交する係止突部を有 する端子と、該係止突部に対する挿通溝と、該挿通溝の終端から回転方向に切欠 された傾斜溝と、該傾斜溝の終端に連成された係止溝とを有するコネクタハウジ ングと、該傾斜溝に対する係合突部を有し、該係止溝に係合した前記係止突部に 該係合突部を当接させる前抜け防止スペーサとにより構成されることを特徴とす る。 In order to achieve the above object, the present invention has a terminal having a locking projection that is orthogonal to the terminal insertion direction, an insertion groove for the locking projection, and a notch in the rotational direction from the end of the insertion groove. A connector housing having an inclined groove and a locking groove formed at the end of the inclined groove, and an engaging protrusion for the inclined groove, and the engaging protrusion engaged with the engaging groove. And a front pull-out prevention spacer that abuts the engaging protrusion.
【０００７】[0007]
コネクタハウジングに端子を挿入する際に、端子の係止突部をコネクタハウジ ングの挿通溝に挿通させる。次いで端子に接続された電線を捻る等して該端子を 回動させ、該係止突部を傾斜溝に沿って摺動させる。該係止突部は傾斜溝から係 止溝に案内され、該係止溝に係合する。さらに該コネクタハウジングに装着した 前抜け防止スペーサの係合突部で該係止突部を押えて端子挿入方向への抜け出し を防止する。 When inserting the terminal into the connector housing, insert the locking protrusion of the terminal into the insertion groove of the connector housing. Next, the terminal is rotated by twisting the electric wire connected to the terminal, and the locking projection is slid along the inclined groove. The locking projection is guided from the inclined groove to the locking groove and engages with the locking groove. Further, the engagement protrusion of the front detachment prevention spacer mounted on the connector housing is pressed against the locking protrusion to prevent the spacer from coming out in the terminal insertion direction.

【００１３】 該スペーサ２１は図３(a) の如くコネクタハウジング１１に端子５を挿入する 前に仮係合させておく。この仮係合はスペーサ２１の係止突起２０をコネクタハ ウジング１１の仮係合突起２３に乗り越して該仮係合突起２３と本係合突起２４ との間に位置させることにより得られる。その状態で該スペーサ２１の係合突部 １２の傾斜面２５とコネクタハウジング１１の傾斜溝９の傾斜底面１７との間に 端子５の係止突片４とほぼ同じ高さの空間２７ができる。The spacer 21 is temporarily engaged before inserting the terminal 5 into the connector housing 11 as shown in FIG. This temporary engagement is obtained by riding the locking projection 20 of the spacer 21 over the temporary engagement projection 23 of the connector housing 11 and positioning it between the temporary engagement projection 23 and the main engagement projection 24. In that state, a space 27 having substantially the same height as the locking projection 4 of the terminal 5 is formed between the inclined surface 25 of the engaging projection 12 of the spacer 21 and the inclined bottom surface 17 of the inclined groove 9 of the connector housing 11. .
【００１４】 そしてコネクタハウジング１１の挿通孔７から端子５の雄タブ２と挿通溝８か ら係止突片４をそれぞれ挿入して、該雄タブ２をコネクタ嵌合室１５内に突出さ せると共に該係止突片４をスペーサ２１の係合突部１２の最低面２５ｂ（図２） に突き当てる。その状態で図３(b) の如く電線２８を手指等で矢印イの如く回転 方向に捻ると共に端子抜き方向ロに引くことにより、該係止突片４は係合突部１ ２の傾斜面２５と傾斜溝９の傾斜面１７に沿って前記空間２７内を移動する。The male tab 2 of the terminal 5 and the locking projection 4 are inserted from the insertion groove 8 through the insertion hole 7 of the connector housing 11 so that the male tab 2 is projected into the connector fitting chamber 15. At the same time, the locking projection 4 is abutted against the lowest surface 25b (FIG. 2) of the engagement projection 12 of the spacer 21. In this state, as shown in FIG. 3 (b), the electric wire 28 is twisted in the rotational direction as shown by the arrow A with a finger or the like and is pulled in the terminal withdrawing direction B, so that the locking projection 4 is formed on the inclined surface of the engaging projection 12. 25 and the inclined surface 17 of the inclined groove 9 move in the space 27.
【００１５】 そして該係止突片４は図３(c) の如く９０°回転して係止溝１０内に係入する 。最後にスペーサ２１を挿入方向に押圧して本係合させ、スペーサ２１の係合突 部１２で該係止突片４を押さえて端子５の前抜けを防止する。この本係合はスペ ーサ２１の係止突起２０をコネクタハウジング１１の本係合突起２４に乗り越し 係合させることにより得られる。Then, as shown in FIG. 3 (c), the locking projection 4 rotates 90 ° and fits into the locking groove 10. Finally, the spacer 21 is pressed in the insertion direction to be fully engaged, and the engaging projection 12 of the spacer 21 presses the locking projection 4 to prevent the terminal 5 from coming off. This main engagement is obtained by overcoming and engaging the locking projection 20 of the spacer 21 with the main engagement projection 24 of the connector housing 11.
【００１６】 ここで万一、コネクタハウジング１１への端子５の挿入が不完全であった場合 には、該スペーサ２１の係合突部１２の最低面２５ｂ（図２）が端子５の係止突 片４に突き当たって該係止突片４を挿通溝８を経て外部へ押し出すから、端子５ の不完全挿入が防止される。If the insertion of the terminal 5 into the connector housing 11 is incomplete, the lowest surface 25 b (FIG. 2) of the engaging projection 12 of the spacer 21 is locked by the terminal 5. Since the locking projection 4 is struck by the projection 4 and pushed out through the insertion groove 8, the incomplete insertion of the terminal 5 is prevented.
【００１７】[0017]
以上の如くに、本考案によれば、端子を傾斜溝に沿って端子抜き方向の係止溝 に係止させるから、端子の抜き出し方向の係止力が格段に向上し、端子の不意な 抜けが確実に防止される。また万一、端子の挿入が不完全であっても、前抜け防 止スペーサの係合突部が端子を押し出すから、端子挿入不良をなくすことができ る。 As described above, according to the present invention, since the terminal is locked in the locking groove in the terminal extracting direction along the inclined groove, the locking force in the terminal extracting direction is remarkably improved and the terminal is unexpectedly pulled out. Is reliably prevented. Even if the terminal is not completely inserted, the engaging protrusion of the front-prevention prevention spacer pushes the terminal out, so that the terminal insertion failure can be eliminated.
