Description
【０００１】[0001]
本考案は、端子のロック機構を備えたコネクタに関し、詳しくは、電線に圧着 した端子をコネクタハウジングの端子収容室に挿入して、リテーナを用いて固定 するようにしたもので、特に、多数の電線群に取り付けた多数の端子を収容固定 する自動車用ワイヤハーネスのコネクタとして好適に用いられるものである。 The present invention relates to a connector having a terminal locking mechanism, and more particularly, to a terminal crimped onto an electric wire inserted into a terminal housing chamber of a connector housing and fixed using a retainer. It is preferably used as a connector for an automobile wire harness that accommodates and fixes a large number of terminals attached to an electric wire group.

従来、この種のコネクタにおける端子の抜け防止機構として、コネクタハウジ ングに一体に係止片を形成したもの、あるいはコネクタハウジングとは別にロッ ク手段、例えば、リテーナ等を設けたものなど多数提供されている。 Conventionally, as a mechanism for preventing the terminals from coming off in this type of connector, there have been provided a large number such as those in which a locking piece is integrally formed in the connector housing, or locking means such as a retainer provided separately from the connector housing. ing.
【０００３】 前記したコネクタハウジングに一体に形成する場合は、コネクタハウジングの 端子収容室の底面あるいは上面に係止片を切り起こして設け、該係止片を端子に 形成した孔あるいは肩部等に係止する構成としている。 しかしながら、上記係止片は比較的小さいため、係止効果が十分でなく、かつ 、端子収容室への端子の着脱により損傷が生じやすい等の問題があった。When integrally formed on the connector housing described above, a locking piece is cut and raised on the bottom surface or the upper surface of the terminal accommodating chamber of the connector housing, and the locking piece is formed in the hole or shoulder formed in the terminal. It is configured to be locked. However, since the locking piece is relatively small, the locking effect is not sufficient, and there is a problem that the terminal is easily damaged by attachment / detachment of the terminal.
【０００４】 そのため、上記コネクタハウジングに形成した係止片と併用して、端子をコネ クタハウジングに収容した状態で外部からハンジングに設けた貫通穴等からリテ ーナあるいはピン等からなるコネクタとは別体のロック手段を挿入し、該ロック 手段を端子に係止させて端子の抜け止めをはかり、二重係止機構を有するコネク タが提供されている。Therefore, in combination with the locking piece formed on the connector housing, a connector including a retainer, a pin or the like from a through hole or the like provided in the housing from the outside with the terminal accommodated in the connector housing is used. There is provided a connector having a double locking mechanism in which a separate locking means is inserted and the locking means is locked to a terminal to prevent the terminal from coming off.
【０００５】 上記二重係止機構を有するコネクタのうち、端子の嵌合面からリテーナを挿入 するタイプのものとして、図８に示すようなコネクタが提供されている。 上記コネクタは、コネクタハウジング１の筒部２に形成した端子収容室３の底 壁の一部に突出片からなるランス部４を設け、該ランス部４の先端面を端子半挿 入検知面５とすると共に、上方突起部を係合突起６としている。また、端子収容 室３の上壁の一部にリテーナ・ロック用係合穴７を形成している。 上記筒部２には、相手コネクタ嵌合側のコネクタハウジング開口部８より挿入 するリテーナ９を外嵌し、該リテーナ９に突設したロック用突起１０を上記ロッ ク用係合穴７に係合し、かつ、端子収容室３内に挿入する端子１１に形成した係 合穴１２に上記ランス部４の係合突起６を係合して２重係止する機構としている 。Among the connectors having the double locking mechanism, a connector as shown in FIG. 8 is provided as a type in which the retainer is inserted from the fitting surface of the terminal. In the above connector, a lance portion 4 formed of a protruding piece is provided on a part of a bottom wall of a terminal accommodating chamber 3 formed in the cylindrical portion 2 of the connector housing 1. At the same time, the upper protrusion is the engaging protrusion 6. Further, a retainer locking engagement hole 7 is formed in a part of the upper wall of the terminal accommodating chamber 3. A retainer 9 to be inserted from the connector housing opening 8 on the mating connector fitting side is externally fitted to the tubular portion 2, and a locking projection 10 projecting from the retainer 9 is engaged with the locking engagement hole 7. The engaging projection 6 of the lance portion 4 is engaged with the engaging hole 12 formed in the terminal 11 to be inserted into the terminal accommodating chamber 3 so as to be doubly locked.
【０００６】[0006]
上記リテーナ９には、端子１１が端子収容室３に完全に挿入していない半挿入 状態の時、それを検知して挿入を停止する手段が設けられている。 即ち、リテーナ９の端子挿通口１３の底面側に半挿入検知ピン１４を設けてお り、端子１１が半挿入状態の時、図示のように、ランス部４の係合突起６が端子 １１の係合穴１２に係合せずに押し下げられる。よって、ランス部４の先端面の 端子半挿入検知面５がリテーナの半挿入検知ピン１４に当接し、リテーナ９の挿 入を停止させる。 The retainer 9 is provided with means for detecting when the terminal 11 is in a semi-inserted state where the terminal 11 is not completely inserted into the terminal accommodating chamber 3 and stopping the insertion. That is, the half insertion detecting pin 14 is provided on the bottom surface side of the terminal insertion opening 13 of the retainer 9, and when the terminal 11 is in the half insertion state, the engaging protrusion 6 of the lance portion 4 is connected to the terminal 11 as shown in the figure. It is pushed down without engaging with the engaging hole 12. Therefore, the terminal half insertion detection surface 5 on the tip end surface of the lance portion 4 contacts the half insertion detection pin 14 of the retainer, and the insertion of the retainer 9 is stopped.
【０００７】 上記したように、端子１１が半挿入の場合、図９において、リテーナ９の半挿 入検知ピン１４の先端面１４aがランス部４の検知面５と当接して、リテーナ９ の挿入を停止されるため、端子の半挿入を検知できる。しかしながら、このよう に、検知しているにもかかわらず、リテーナ９を横方向にコジリながら過度の力 を用いて押し込むと、ランス部４が横方向へ逃げて、例えば、図８で点線で示す ようにランス部４の検知面５が横方向へ折れ、図９における実線で示す半挿入検 知ピン１４と鎖線で示す検知面５の位置になり、リテーナ９は無理に押し込み可 能となる。As described above, when the terminal 11 is half-inserted, in FIG. 9, the tip end surface 14 a of the half-insertion detection pin 14 of the retainer 9 comes into contact with the detection surface 5 of the lance portion 4, and the retainer 9 is inserted. Since it is stopped, half insertion of the terminal can be detected. However, even if the retainer 9 is detected in this way, if the retainer 9 is pushed laterally and pushed in with an excessive force, the lance portion 4 escapes laterally, and is shown by a dotted line in FIG. 8, for example. As described above, the detection surface 5 of the lance portion 4 is bent in the lateral direction to the positions of the half-insertion detection pin 14 shown by the solid line in FIG. 9 and the detection surface 5 shown by the chain line, and the retainer 9 can be forcibly pushed.
【０００８】 上記半挿入検知ピン１４およびランス部４が共に薄巾で小片からなるため、無 理な力での押し込みにより容易に変形し、よって、上記したように、端子１１が 半挿入状態のままで、リテーナ９のロック用突起１０がリテーナ・ロック用係合 穴７に係合されてリテーナ９がセットされてしまう欠点がある。Since the half-insertion detection pin 14 and the lance portion 4 are both thin and made of small pieces, they are easily deformed by pushing in with an unreasonable force. Therefore, as described above, the terminal 11 is in the half-inserted state. In addition, there is a drawback that the locking projection 10 of the retainer 9 is engaged with the retainer / lock engagement hole 7 to set the retainer 9.
【０００９】 本考案は上記した欠点を解消せんとするもので、端子が半挿入状態の場合に、 リテーナの無理な押し込みを確実に阻止して、端子を正規位置まで完全に挿入さ れている場合のみ、リテーナのセットを可能とするものである。The present invention is intended to solve the above-mentioned drawbacks. When the terminal is in the half-inserted state, the retainer is securely prevented from being forcedly pushed, and the terminal is completely inserted to the regular position. Only in this case is it possible to set the retainer.
【００１０】[0010]
従って、本考案は、コネクタハウジングの筒部に形成した端子収容室の底壁に 突出片からなるランス部を設け、該ランス部の先端面を端子半挿入検知面とする と共に上方突出部を端子との係合突起とし、かつ、端子収容室の壁面にリテーナ ・ロック用係合穴を設ける一方、 上記端子収容室を形成した筒部に対して、相手方コネクタ嵌合側のコネクタハ ウジング開口部よりリテーナを挿入して外嵌し、該リテーナに突設したロック用 突起を上記リテーナ・ロック用係合穴に係合する構成として二重係止機構付きコ ネクタにおいて、 上記リテーナの端子挿通口の底面に端子半挿入検出部を設け、該端子半挿入検 出部の先端面が、端子半挿入時に押し下げられる上記ランス部先端の端子半挿入 検知面と互いに当接するように位置決め設定し、かつ、該端子半挿入検出部の巾 方向両側にランス部の巾より大きい巾をあけてストッパ用突条を設けていること を特徴とするコネクタ。 Therefore, according to the present invention, a lance portion, which is a protruding piece, is provided on the bottom wall of the terminal accommodating chamber formed in the cylindrical portion of the connector housing, and the tip surface of the lance portion serves as the terminal half-insertion detection surface and the upper protruding portion is the terminal While providing a retainer / locking engagement hole on the wall surface of the terminal accommodating chamber, the connector housing opening on the mating connector mating side with respect to the tubular part forming the terminal accommodating chamber In a connector with a double locking mechanism having a structure in which a retainer is inserted and externally fitted, and a locking projection protruding from the retainer is engaged with the retainer / locking engagement hole, the terminal insertion port of the retainer is A terminal half-insertion detector is provided on the bottom surface, and the terminal half-insertion detector is positioned and set so that the tip surface of the terminal half-insertion detector comes into contact with the terminal half-insertion detection surface of the tip of the lance portion that is pushed down when the terminal half is inserted. Further, the connector is characterized in that stopper ridges are provided on both sides in the width direction of the terminal half-insertion detection portion with a width larger than the width of the lance portion.
【００１１】[0011]
上記したように、リテーナに形成している端子半挿入検出部の巾方向の両側に ストッパ用突条を設けているため、端子が半挿入状態である場合、端子により押 し下げられたランス部の先端がリテーナの端子半挿入検出部の端面に当接すると 共に、その巾方向両側がストッパ用突条で挟まれる。よって、リテーナをゴジリ ながら無理に押し込んでも、ストッパ用突条の間にランス部が挟まれたままで横 方向に逃げることが出来ず、リテーナの挿入を確実に防止することが出来る。 As described above, the stopper ridges are provided on both sides in the width direction of the terminal half-insertion detection part formed on the retainer.Therefore, when the terminal is in the half-insertion state, the lance part pushed down by the terminal is pressed. The tip of the contact part comes into contact with the end face of the retainer terminal half-insertion detection part, and both sides in the width direction are sandwiched by the stopper projections. Therefore, even if the retainer is forcibly pushed in, it cannot be laterally escaped with the lance portion being sandwiched between the stopper projections, and the retainer can be reliably prevented from being inserted.

The rubber ring 25 and the retainer 28 allow the terminal 25 to accommodate the terminal 25. The inside is sealed.
【００１４】 端子収容室２６の底壁には、突出片からなり弾性的にたわむように形成したラ ンス部３０を設けている。 ランス部３０は、上面側に上方突出部からなる係合突起３０aを設けている。 該係合突起３０aは、端子収容室２６内に端子２５を完全に挿入した状態で、端 子２５の下面側に設けた係合穴２５aに係合する一方、端子２５が半挿入状態の 場合には先端部が端子２５の下面に当接し、よって、ランス部３０が弾性的に下 方へ屈曲されるようにしている。On the bottom wall of the terminal accommodating chamber 26, there is provided a lance portion 30 formed of a projecting piece and formed so as to elastically bend. The lance portion 30 is provided with an engagement protrusion 30a formed of an upward protrusion on the upper surface side. The engaging projection 30a engages with the engaging hole 25a provided on the lower surface side of the terminal 25 in the state where the terminal 25 is completely inserted into the terminal accommodating chamber 26, while the terminal 25 is in the semi-inserted state. The tip of the lance contacts the lower surface of the terminal 25, so that the lance 30 is elastically bent downward.
【００１５】 また、ランス部３０の先端面は、後述するようにリテーナ２８の端子半挿入検 出部３３の先端面と係合して端子２５の半挿入状態を検出する端子半挿入検知面 ３０bを構成している。 端子収容室２６の上壁には、後述するリテーナ２８の係合ロック用突起３２b と係合するリテーナ・ロック用係合穴２６aを設けている。The tip surface of the lance portion 30 engages with the tip surface of the terminal half-insertion detection portion 33 of the retainer 28 to detect the half-insertion state of the terminal 25, as will be described later, and the terminal half-insertion detection surface 30b. Is composed of. The upper wall of the terminal accommodating chamber 26 is provided with a retainer lock engagement hole 26a that engages with an engagement lock protrusion 32b of the retainer 28 described later.
【００１６】 リテーナ２８は、図２及び図３に示すように、略升形状であって、上記ハウジ ング２１相手方コネクタ嵌合側の開口部から挿入して、筒部２３に開口部２８a を外嵌する構成としている。 上記開口部２８aと対向する端面２８bには、相手方端子挿入口３１を設け、該 相手方端子挿入口３１の図中上下端部に、ロックアーム３２及び端子半挿入検出 部３３を設けている。As shown in FIGS. 2 and 3, the retainer 28 has a substantially box shape, and is inserted from the opening of the housing 21 on the mating connector mating side, and the opening 28 a is inserted into the cylindrical portion 23. It is configured to fit. A mating terminal insertion port 31 is provided on the end surface 28b facing the opening 28a, and a lock arm 32 and a terminal half insertion detection unit 33 are provided at the upper and lower ends of the mating terminal insertion port 31 in the figure.
【００１７】 ロックアーム３２は、弾性的にたわむ腕状部３２aの先端にロック用突起３２b を設けてなり、リテーナ２８をハウジング２１の筒部２３に外嵌した状態で端子 収容室２６のリテーナ・ロック用係合穴２６aと係合して、よって、リテーナ２ ８を筒部２８にロックするように構成している。 本実施例では、上記したように端子２５の係合穴２５aにランス部３０の係合 突起３０aを係合すると共に、リテーナ２８のロック用突起３２bを端子収容室２ ６のリテーナ・ロック用係合穴２６aに係合する構成として、二重係止機構のコ ネクタとしいる。The lock arm 32 is provided with a locking protrusion 32 b at the tip of an elastically flexible arm portion 32 a, and the retainer 28 of the terminal accommodating chamber 26 is fitted onto the tubular portion 23 of the housing 21. The retainer 28 is configured to be locked to the tubular portion 28 by being engaged with the locking engagement hole 26a. In this embodiment, as described above, the engaging projection 30a of the lance portion 30 is engaged with the engaging hole 25a of the terminal 25, and the locking projection 32b of the retainer 28 is engaged with the retainer / locking member of the terminal accommodating chamber 26. A connector of a double locking mechanism is used as a structure for engaging the dowel hole 26a.
【００１８】 上記のようにリテーナ２８の端子挿入口３１の底面に設けた端子半挿入検出部 ３３は、図４及び図５に拡大して示すように、断面略Ｔ字状であって、巾方向の 両側に薄板状のストッパ用突条３５Ａ,３５Ｂを設けた構成としている。As described above, the terminal half-insertion detecting portion 33 provided on the bottom surface of the terminal insertion opening 31 of the retainer 28 has a substantially T-shaped cross section and a width as shown in the enlarged view of FIGS. 4 and 5. Thin plate-like stopper projections 35A and 35B are provided on both sides in the direction.
【００１９】 端子半挿入検出部３３の先端面３３aは、上記ランス部３０の端子半挿入検知 面３０bと当接して端子２５がハウシジング２１の端子収容室２６内に完全に挿 入されない状態では、リテーナ２８を筒部２３に外嵌することができないような 位置に位置設定している。即ち、端子２５が半挿入であってランス部３０が下方 に屈曲した状態で、リテーナ２８を筒部２３に挿入すると、図５中二点鎖線で示 すように、ランス部３０の端子半挿入検知面３０bが先端面３３aに当接して、よ って、リテーナ２８が筒部２３に外嵌されないように位置設定している。The tip surface 33 a of the terminal half-insertion detecting portion 33 contacts the terminal half-insertion detecting surface 30 b of the lance portion 30 so that the terminal 25 is not completely inserted into the terminal accommodating chamber 26 of the housing 21, The retainer 28 is set at a position where it cannot be fitted onto the tubular portion 23. That is, when the retainer 28 is inserted into the tubular portion 23 in a state where the terminal 25 is half-inserted and the lance portion 30 is bent downward, as shown by the chain double-dashed line in FIG. The detection surface 30b is in contact with the tip end surface 33a, so that the retainer 28 is positioned so as not to be fitted onto the cylindrical portion 23.
【００２０】 一方、端子半挿入検出部３３の上面３３bの位置は、端子収容室２６内に端子 ２５が完全に挿入された状態でリテーナ２８を筒部２３に外嵌すると、図５中一 点鎖線で示すように、ランス部３０の端子半挿入検知面３０bが、上記先端面 ３４aと当接せず、該上面３３bの上方を通過することができるように設定してい る。On the other hand, the position of the upper surface 33b of the terminal half-insertion detecting portion 33 is one point in FIG. 5 when the retainer 28 is fitted onto the tubular portion 23 while the terminal 25 is completely inserted into the terminal accommodating chamber 26. As shown by the chain line, the terminal half-insertion detecting surface 30b of the lance portion 30 is set so as to be able to pass above the upper surface 33b without abutting on the tip surface 34a.
【００２１】 上記ストッパ用突条３５Ａ,３５Ｂは、その先端面３５Ａ−１,３５Ｂ−１が上 記端子半挿入検出部３３の先端面３３aよりもリテーナ２８の挿入方向に僅かに 突出するように設けている。また、ストッパ用突条３５Ａ,３５Ｂの間隔Ｗは、 上記したハウジング２１のランス部３０の巾よりも大きく設定している。The stopper projections 35A, 35B have their tip surfaces 35A-1, 35B-1 slightly projected in the inserting direction of the retainer 28 than the tip surface 33a of the above-mentioned terminal half-insertion detecting portion 33. It is provided. The distance W between the stopper protrusions 35A and 35B is set to be larger than the width of the lance portion 30 of the housing 21 described above.
【００２２】 本実施例では、上記のようにリテーナ２８挿入方向の位置及び巾を上記のよう に設定したストッパ用突条３５Ａ、３５Ｂを設けているため、ランス部３０の端 子半挿入検知面３０aが端子半挿入検出部３３の先端面３３aに当接する状態で、 リテーナ２８を過度の力で押し込んだ場合に、端子半挿入検知面３０aが先端面 ３３aから横方向にずれようとしても、これらストッパ用突条３５Ａ,３５Ｂに横 方向のずれが拘束され、端子半挿検知面３０aはストッパ用突条３５Ａ,３５Ｂに 挟まれた状態で先端面３３aからずれることがない。In this embodiment, since the stopper protrusions 35A and 35B having the positions and widths in the inserting direction of the retainer 28 set as described above are provided, the terminal half insertion detection surface of the lance portion 30 is provided. When the retainer 28 is pushed in with excessive force while the terminal 30a is in contact with the tip surface 33a of the terminal half-insertion detecting portion 33, even if the terminal half-insertion detection surface 30a is displaced laterally from the tip surface 33a, The stopper protrusions 35A, 35B restrain the lateral displacement, and the terminal half-insertion detection surface 30a is not displaced from the tip surface 33a while being sandwiched between the stopper protrusions 35A, 35B.
【００２３】 次に、上記した構成の本実施例に係るコネクタの組立てについて説明する。 図６に示すように、矢印Ａ方向に端子２５を端子収容室２６に挿入する。 ランス部３０は、突起部３０aが端子２５の下側部と当接するため図面中下方に 屈曲した状態となるが、端子２５を完全に端子収容室２６に挿入すると、端子の 係合穴２５aに嵌まり込んで係合し、よって、ランス部３０は端子２５の挿入方 向に対して真直な状態となる。Next, the assembling of the connector according to this embodiment having the above-mentioned configuration will be described. As shown in FIG. 6, the terminal 25 is inserted into the terminal accommodating chamber 26 in the direction of arrow A. The lance portion 30 is bent downward in the drawing because the protrusion 30a abuts the lower portion of the terminal 25. The lances 30 are fitted and engaged with each other, and thus the lance portion 30 is in a straight state with respect to the insertion direction of the terminals 25.
【００２４】 この状態で、リテーナ２８を筒部２３に挿入していくと、ランス部３０の端子 半挿入検知面３０aは端子半挿入検出部３３の上面３３b側を通過するため、リテ ーナ２８を挿入していくことができる。リテーナ２８のロック用係合突起３２b が端子収容部２６のロック用係合穴２６aに係合し、よって、リテーナ２８を筒 部２３に外嵌し、端子収容室２６内の端子２５をロックすることができる。When the retainer 28 is inserted into the tubular portion 23 in this state, the terminal half-insertion detecting surface 30 a of the lance portion 30 passes through the upper surface 33 b side of the terminal half-insertion detecting portion 33, so that the retainer 28 is inserted. Can be inserted. The locking engagement projection 32b of the retainer 28 engages with the locking engagement hole 26a of the terminal accommodating portion 26, so that the retainer 28 is fitted onto the cylindrical portion 23 and the terminal 25 in the terminal accommodating chamber 26 is locked. be able to.
【００２５】 一方、図７で示すように、端子２５が完全に端子収容室２６内に挿入されてい ない場合には、ランス部３０は突起部３０aが端子２５の下側に当接した状態の ままであり、ランス部３０は図中下方に屈曲した状態のままである。そのため、 リテーナ２８を挿入していくと、ランス部３０の端子半挿入検知面３０aが端子 半挿入検出部３３の先端面３３aと当接して、リテーナ２８が挿入されるのを阻 止する。 この時、リテーナ２８に過度の力を加えて横方向にコジリながら押し込んだ場 合にもランス部３０の先端は、ストッパ用突条３５Ａ、３５Ｂの間に挟まれるた め、端子半挿入検出面３０aと先端面３３aは、横方向にずれることがなく、端子 ２５が半挿入状態でリテーナ２８が筒部２３が外嵌、ロックするのを確実に防止 することができる。On the other hand, as shown in FIG. 7, when the terminal 25 is not completely inserted into the terminal accommodating chamber 26, the lance portion 30 has a state in which the protrusion 30 a is in contact with the lower side of the terminal 25. Therefore, the lance portion 30 remains bent downward in the figure. Therefore, as the retainer 28 is inserted, the terminal half-insertion detecting surface 30a of the lance portion 30 abuts on the tip end surface 33a of the terminal half-insertion detecting portion 33 to prevent the retainer 28 from being inserted. At this time, even if the retainer 28 is pushed in laterally while being bent excessively, the tip of the lance portion 30 is caught between the stopper protrusions 35A and 35B, so that the terminal half-insertion detection surface is detected. The tip 30a and the tip surface 33a do not shift laterally, and it is possible to reliably prevent the retainer 28 from externally fitting and locking the tubular portion 23 when the terminal 25 is half inserted.
【００２６】 本考案は上記実施例に限定されるものではなく、種々の変形が可能である。例 えば、ハウジングやリテーナの形状等は上記のものに限定されず、ハウジング側 にランス部を設けると共に、リテーナ側の端子半挿入部検出部を設けた構成とし たものであればよい。 また、上記実施例に係るコネクタは単極式であるが、本考案は多極式コネクタ にも適用することができる。The present invention is not limited to the above embodiment, but various modifications can be made. For example, the shapes of the housing and the retainer are not limited to those described above, and any configuration may be used as long as the housing has the lance portion and the retainer-side terminal half-insertion portion detection portion is provided. Further, although the connector according to the above embodiment is a single pole type, the present invention can be applied to a multipole type connector.
【００２７】[0027]
以上の説明から明らかなように、本考案に係るコネクタでは、端子が半挿入状 態のままリテーナを挿入する場合に、ハウジング側のランス部の先端面である端 子半挿入検知面と当接するリテーナ側の端子半挿入検出部の巾方向の両側にスト ッパ用突条を設けているため、端子半挿入状態でリテーナをコジリながら無理に 押し込もうとしても、ランス部の先端はこれらストッパ用突状に挟まれて上記先 端面と端子半挿入検知面が横方向にずれるを防止することができる。 As is clear from the above description, in the connector according to the present invention, when the retainer is inserted while the terminal is in the half-inserted state, it comes into contact with the terminal half-insertion detection surface which is the tip surface of the lance portion on the housing side. Since the stopper ridges are provided on both sides in the width direction of the terminal half-insertion detection part on the retainer side, even if you try to force the retainer while twisting the retainer with the terminal half-inserted state, the tip of the lance part will stop with these stoppers. It is possible to prevent the front end face and the terminal half-insertion detecting face from being laterally displaced by being sandwiched in a projecting shape.
【００２８】 そのため、本考案に係るコネクタでは、端子が半挿入状態の場合に、リテーナ をハウジングに挿入してロックしてしまうのを確実に防止することができ、作業 性の確実性を向上することができる。Therefore, in the connector according to the present invention, it is possible to reliably prevent the retainer from being locked by being inserted into the housing when the terminal is in the half-inserted state, and the reliability of workability is improved. be able to.
