Description

本発明は、コネクタハウジング内に挿入された端子をスペーサで係止させるスペーサ付きコネクタに関するものである。   The present invention relates to a connector with a spacer for locking a terminal inserted into a connector housing with a spacer.

図８（ａ）（ｂ）は、従来のスペーサ付きコネクタの一形態を示すものである（特許文献１参照）。   8 (a) and 8 (b) show one form of a conventional connector with a spacer (see Patent Document 1).

図８（ａ）の如く、このコネクタ７６１は、絶縁樹脂製のコネクタハウジング６２の底壁のスペーサ挿入孔６３の開口から上向きに挿入される絶縁樹脂製の端子係止用のスペーサ６４を備えたものである。スペーサ６４はリテーナとも呼称される端子係止部材である。   As shown in FIG. 8A, the connector 761 includes an insulating resin terminal locking spacer 64 that is inserted upward from the opening of the spacer insertion hole 63 on the bottom wall of the insulating resin connector housing 62. Is. The spacer 64 is a terminal locking member also called a retainer.

図８（ｂ）にコネクタハウジング６２をハッチングで示し、スペーサ６４を実線で示す如く、コネクタハウジング６２は上下二段に端子収容室６５を有し、上段の中央にはコネクタ同士のロック用のロックアーム６６を有し、スペーサ６４は各端子収容室６５の位置に応じた端子係止用の突部６７を上向きに有している。   As shown in FIG. 8B, the connector housing 62 is indicated by hatching, and the spacer 64 is indicated by a solid line. The connector housing 62 has terminal receiving chambers 65 in two upper and lower stages, and a lock for locking connectors between the upper stages. The spacer 64 has an arm 66, and has a protrusion 67 for locking the terminal upward corresponding to the position of each terminal accommodating chamber 65.

スペーサ６４は左右端に側壁６８を有し、側壁６８の内側上部に係止用の爪部６９を有し、コネクタハウジング６４は、爪部６９を係合させる下側の仮係止突起７０と上側の本係止突起７１とを有している。スペーサ６４は中央の側壁７３の上部内面に係止突起７４を有し、係止突起７４はコネクタハウジング６２の中央の凹部７２の上壁面７５に係合する。図８（ｂ）はスペーサ６４の本係止状態であり、仮係止状態で中央の係止突起７４は上壁面７５の下側の空間７６内に位置する。   The spacer 64 has side walls 68 at the left and right ends, and has a locking claw portion 69 on the inner upper portion of the side wall 68. The connector housing 64 includes a lower temporary locking projection 70 for engaging the claw portion 69. It has an upper main locking projection 71. The spacer 64 has a locking projection 74 on the upper inner surface of the central side wall 73, and the locking projection 74 engages with the upper wall surface 75 of the recess 72 in the center of the connector housing 62. FIG. 8B shows the main locking state of the spacer 64, and the central locking protrusion 74 is located in the space 76 below the upper wall surface 75 in the temporary locking state.

JP 2006-100237 A (FIGS. 3 and 5)

しかしながら、上記従来のスペーサ付きコネクタ６１にあっては、スペーサ６４の中央寄りの係止突起７４がコネクタハウジング６２の上壁（符号７５で代用）を乗り越えて上壁面７５に係合する際に、スペーサ６４が矢印Ａのように下向きに反り変形を生じ、スペーサ６４の左右両側の仮係止及び本係止用の爪部６９が外向きに開き変形し、爪部６９とコネクタハウジング６４の各係止突起７０，７１との係合力が低下し兼ねないという懸念があった。   However, in the conventional connector 61 with the spacer, when the locking projection 74 near the center of the spacer 64 gets over the upper wall (represented by reference numeral 75) of the connector housing 62 and engages with the upper wall surface 75, The spacer 64 is warped and deformed downward as indicated by an arrow A, and the temporary locking and full locking claw portions 69 on both the left and right sides of the spacer 64 are opened and deformed outward, and each of the claw portion 69 and the connector housing 64 is deformed. There was a concern that the engaging force with the locking protrusions 70 and 71 could be reduced.

これを防ぐために中央の係止突起７４を小さく形成した場合は、係止突起７４と上壁面７５との係合力が低下するという問題を生じてしまい、何れにおいてもコネクタハウジング６２へのスペーサ６４の係止力が低下し、車両の振動等によってスペーサ６４の係止外れを起こして端子７７の係止力を低下させ兼ねないという懸念があった。   In order to prevent this, if the central locking projection 74 is formed small, there arises a problem that the engagement force between the locking projection 74 and the upper wall surface 75 is reduced. There is a concern that the locking force is reduced, and the locking of the terminal 77 may be reduced by causing the spacer 64 to be unlocked due to vehicle vibration or the like.

本発明は、上記した点に鑑み、スペーサの中央寄りの係止部をコネクタハウジングに係合させる際のスペーサの反りを防ぎ、スペーサの両側の係止部及び中央側の係止部をコネクタハウジングに十分な係止力で係合させることのできるスペーサ付きコネクタを提供することを目的とする。   In view of the above-described points, the present invention prevents the spacer from warping when the locking portion near the center of the spacer is engaged with the connector housing, and the locking portions on both sides of the spacer and the locking portions on the central side are connected to the connector housing. It is an object of the present invention to provide a connector with a spacer that can be engaged with each other with a sufficient locking force.

上記目的を達成するために、本発明の請求項１に係るスペーサ付きコネクタは、コネクタハウジングの底壁のスペーサ挿入孔からスペーサを挿入してコネクタハウジング内の端子を係止するスペーサ付きコネクタにおいて、前記コネクタハウジングの左右両側の仮係止及び本係止用の被係止部の外側に係合する第一係止部が前記スペーサの左右両側に設けられ、該スペーサが中央寄りに左右一対の可撓性の上向きの係止突壁を有し、該係止突壁が第二係止部を有し、該コネクタハウジングが、中央寄りの左右の壁部に、各係止突壁を係合させる各切欠孔を有し、各切欠孔が、該係止突壁を傾斜面で摺接して内向きに撓ませつつ、該第二係止部を係合させるガイド突壁を有することを特徴とする。   To achieve the above object, a connector with a spacer according to claim 1 of the present invention is a connector with a spacer for inserting a spacer from a spacer insertion hole in a bottom wall of the connector housing and locking a terminal in the connector housing. A first locking portion that engages the outside of the locked portion for temporary locking and main locking on both the left and right sides of the connector housing is provided on the left and right sides of the spacer, and the spacer is a pair of left and right at the center. A flexible upward locking projection wall, the locking projection wall has a second locking portion, and the connector housing engages each locking projection wall with the left and right wall portions closer to the center. Each notch hole to be fitted, and each notch hole has a guide projection wall that engages the second locking portion while bending the locking projection wall in an inclining manner by sliding on the inclined surface. Features.

上記構成により、スペーサを仮係止状態からコネクタハウジング内に押し込むに伴って、例えば一対の係止突壁の上側の傾斜面がコネクタハウジングの切欠孔内のガイド突壁に当接（摺接）しつつ、一対の係止突壁が内向きに撓んでスペーサの進入を許容し、係止突壁の第二係止部がガイド突壁を乗り越えた時点で、係止突壁が外向きに弾性的に復元し、第二係止部が切欠孔内でガイド突壁に係合する。これと同時にスペーサの両側の第一係止部がコネクタハウジングの被係止部に外側から本係合する。すなわち、第一係止部が被係止部を乗り越えつつ外向きに撓み、乗り越えた時点で内向きに弾性的に復元して被係止部に係合（本係止）する。   With the above configuration, as the spacer is pushed into the connector housing from the temporarily locked state, for example, the upper inclined surfaces of the pair of locking projection walls abut (sliding contact) with the guide projection walls in the notch holes of the connector housing. However, the pair of locking projection walls bend inward to allow the spacer to enter, and when the second locking portion of the locking projection wall gets over the guide projection wall, the locking projection walls face outward. Elastically restored, the second locking portion engages with the guide protrusion wall in the cutout hole. At the same time, the first locking portions on both sides of the spacer are finally engaged with the locked portions of the connector housing from the outside. That is, the first locking portion bends outward while getting over the locked portion, and when it gets over, it is elastically restored inward and engaged (mainly locked) with the locked portion.

このように、中央寄りの係止突壁が内向きに撓むことで、スペーサが従来のように第一係止部と被係止部との係合力を弱める方向に反ることが防止され、寧ろ第一係止部と被係止部との係合力を高める方向に反る傾向となるので、コネクタハウジングに対する両側の第一係止部と中央の第二係止部との両方の係止力が高く維持される。なお、傾斜面は係止突壁に代えてガイド突壁に設けてもよい。第二係止部としては、係止突壁の前後方向に設けた突起又は係止突壁の中間部に設けた孔部を採用可能であり、孔部の場合は、係止突壁の復元と同時にガイド突壁が孔部内に進入係合する。   In this way, the locking projection wall closer to the center bends inward, so that the spacer is prevented from warping in the direction of weakening the engagement force between the first locking portion and the locked portion as in the prior art. On the other hand, since it tends to warp in the direction of increasing the engagement force between the first locking portion and the locked portion, both the first locking portion on both sides and the central second locking portion with respect to the connector housing are engaged. High stopping power is maintained. The inclined surface may be provided on the guide protrusion wall instead of the locking protrusion wall. As the second locking part, a protrusion provided in the front-rear direction of the locking projection wall or a hole provided in the middle part of the locking projection wall can be adopted. At the same time, the guide protrusion wall enters and engages in the hole.

請求項２に係るスペーサ付きコネクタは、請求項１記載のスペーサ付きコネクタにおいて、前記第二係止部が前記係止突壁の上部において前及び／又は後に設けられた突起であり、前記傾斜面が該突起の上端に設けられ、前記ガイド突壁の上側に該突起を係合させる前記切欠孔の幅広部が設けられたことを特徴とする。   The connector with spacer according to claim 2 is the connector with spacer according to claim 1, wherein the second locking portion is a protrusion provided at the front and / or rear of the locking protrusion wall, and the inclined surface. Is provided at the upper end of the projection, and a wide portion of the cutout hole for engaging the projection is provided on the upper side of the guide projection wall.

上記構成により、スペーサを仮係止状態からコネクタハウジング内に押し込むに伴って、一対の係止突壁の突起の傾斜面がコネクタハウジングの切欠孔内のガイド突壁に当接（摺接）しつつ、一対の係止突壁が内向きに撓んでスペーサの進入を許容し、係止突壁の前後方向の突起がガイド突壁を乗り越えた時点で、係止突壁が外向きに弾性的に復元し、突起が切欠孔の幅広部内に進入係合する。これと同時にスペーサの両側の係止部がコネクタハウジングの被係止部に外側から本係合する。すなわち、係止部が被係止部を乗り越えつつ外向きに撓み、乗り越えた時点で内向きに弾性的に復元して被係止部に係合（本係止）する。係止突壁に前後一対の突起を設けた場合は、コネクタハウジングの前後一対のガイド突壁の上側の幅広部内に均一な力で係合し、スペーサの挿入時における前後方向の倒れが防止される。   With the above configuration, as the spacer is pushed into the connector housing from the temporarily locked state, the inclined surfaces of the protrusions of the pair of locking protruding walls come into contact (sliding contact) with the guide protruding walls in the notch holes of the connector housing. On the other hand, the pair of locking projection walls bend inward to allow the spacer to enter, and when the projection in the front-rear direction of the locking projection wall gets over the guide projection wall, the locking projection walls are elastic outward. And the protrusion enters and engages in the wide portion of the cutout hole. At the same time, the locking portions on both sides of the spacer are finally engaged with the locked portions of the connector housing from the outside. That is, the latching portion bends outward while getting over the locked portion, and when it gets over, it is elastically restored inward and engaged (mainly locked) with the locked portion. When a pair of front and rear projections are provided on the locking projection wall, they are engaged with a uniform force within the wide portion on the upper side of the pair of front and rear guide projection walls of the connector housing, preventing the front and rear from falling when the spacer is inserted. The

請求項３に係るスペーサ付きコネクタは、請求項２記載のスペーサ付きコネクタにおいて、前記傾斜面の押圧操作で前記係止突壁と前記切欠孔との係合が解除されることを特徴とする。   A connector with a spacer according to a third aspect is the connector with a spacer according to the second aspect, wherein the engagement between the locking projection wall and the notch hole is released by a pressing operation of the inclined surface.

上記構成により、作業者が傾斜面を内向きに摘んで、あるいは傾斜面を鉛直に治具棒等で押圧して内向きの押圧力を作用（操作）させて、係止突壁を弾性的に撓ませることで、突起が切欠孔の幅広部から離脱し、そのままスペーサを抜き出すことで係止突壁の係止解除がスムーズ且つ容易に行われる。   With the above configuration, the operator picks the inclined surface inward, or presses the inclined surface vertically with a jig bar or the like to apply (operate) the inward pressing force, thereby elastically engaging the locking projection wall. The protrusion is detached from the wide portion of the notch hole and the spacer is extracted as it is, so that the locking projection wall can be unlocked smoothly and easily.

請求項１記載の発明によれば、コネクタハウジングにスペーサを挿入する際におけるスペーサの両側の第一係止部と中央寄りの係止突壁との撓み方向が逆であるので、スペーサに有害な反りを生じることがなく、コネクタハウジングに対する両側の第一係止部と中央寄りの第二係止部との両方の係止がしっかりと確実に行われ、車両の振動等によりスペーサの不意な係止外れを起こすことがなく、端子の係止が経時的にしっかりと行われ、コネクタ相互の電気的接続の信頼性が向上する。   According to the first aspect of the present invention, since the bending directions of the first locking portions on both sides of the spacer and the locking projection walls closer to the center when inserting the spacer into the connector housing are reversed, it is harmful to the spacer. There is no warping, and both the first locking part on both sides and the second locking part near the center of the connector housing are securely and securely engaged. The terminal is securely locked over time without causing a detachment, and the reliability of electrical connection between the connectors is improved.

請求項２記載の発明によれば、例えば係止突壁の前後一対の突起がコネクタハウジングの切欠孔の幅広部内に均一に係合することで、スペーサの前後方向の倒れが防止され、これにより、コネクタハウジング内へのスペーサの挿入がスムーズに行われ、コネクタハウジングの被係止部への両側の係止部の係止もスムーズ且つ確実に行われる。   According to the second aspect of the invention, for example, the pair of front and rear projections of the locking projection wall are uniformly engaged in the wide portion of the cutout hole of the connector housing, thereby preventing the spacer from collapsing in the front-rear direction. The spacer is smoothly inserted into the connector housing, and the locking portions on both sides to the locked portion of the connector housing are smoothly and reliably engaged.

請求項３記載の発明によれば、傾斜面に内向きの押圧力を作用させることで、切欠孔からの係止突壁の係止解除すなわちスペーサの係止解除をスムーズ且つ容易に行うことができる。   According to the third aspect of the present invention, it is possible to smoothly and easily perform the unlocking of the locking projection wall from the notch hole, that is, the unlocking of the spacer, by applying an inward pressing force to the inclined surface. it can.

The spacer insertion hole 18 is opened horizontally in the transverse direction of the housing as shown in FIG. 3B in the middle of the front-rear direction (connector fitting / removing direction) of the connector housing 2 and orthogonal to the upper and lower terminal accommodating chambers 22. Communicate. Each terminal accommodating chamber 22 is partitioned by upper, lower, left and right partition walls 33. A flexible locking lance (not shown) is provided in the terminal accommodating chamber portion 2a in front of the spacer insertion hole 18 of the connector housing 2. At the rear end of the connector housing 2, a hook part 34 for fitting / removing operation is provided.

スペーサ挿入孔１８におけるスペーサ１の仮係止状態で電線付きの雌端子（図示せず）がコネクタハウジング２の後部開口（図示せず）から端子収容室２２内に挿入され、雌端子の矩形筒状の電気接触部の孔部等が係止ランス（図示せず）で一次係止され、次いでスペーサ１が上向きに押し込まれて本係止されると同時に、スペーサ１の係止用の突部１６（図１）で雌端子の電気接触部の後段部等が二次（二重）係止される。スペーサ１は端子挿入方向（コネクタ嵌合方向）に直交してコネクタハウジング２内に挿入される。   A female terminal (not shown) with an electric wire is inserted into the terminal accommodating chamber 22 from the rear opening (not shown) of the connector housing 2 in a temporarily locked state of the spacer 1 in the spacer insertion hole 18 and is a rectangular tube of the female terminal. A hole or the like of the electric contact portion is primarily locked by a locking lance (not shown), and then the spacer 1 is pushed upward to be fully locked, and at the same time, a protrusion for locking the spacer 1 At 16 (FIG. 1), the rear portion of the electrical contact portion of the female terminal is secondary (double) locked. The spacer 1 is inserted into the connector housing 2 perpendicular to the terminal insertion direction (connector fitting direction).

図３（ａ）の如く、コネクタハウジング２の左右端に一対の縦長矩形状の型抜き用の孔部３５が設けられ、孔部３５内に下側の仮係止突起３６と上側の本係止突起３７とが隣接して外向きに設けられている。仮係止突起３６は下側の緩勾配の傾斜面３６ａと上側の水平な仮係止面３６ｂとを有し、本係止突起３７は上下の急勾配の傾斜面３７ａ，３７ｂを有している。   As shown in FIG. 3A, a pair of vertically elongated rectangular punching holes 35 are provided at the left and right ends of the connector housing 2, and the lower temporary locking projections 36 and the upper main hooks are provided in the holes 35. A stop projection 37 is provided adjacent and outward. The temporary locking projection 36 has a lower gentle inclined surface 36a and an upper horizontal temporary locking surface 36b, and the final locking projection 37 has upper and lower steep inclined surfaces 37a and 37b. Yes.

図１のスペーサ１の左右の側壁５の内面側の水平な係止爪２０が下側の仮係止突起３６を乗り越えて上下の係止突起３６，３７の間に係合して仮係止され、爪２０が上側の本係止突起３７を乗り越えて本係止される。鍔状の爪２０は上下方向の可撓性を有しており、それによって仮係止・本係止が小さな操作力でスムーズに且つ大きな係止代でしっかりと確実に行われる。爪２０は各突起３６，３７に外側から係合する。   The horizontal locking claw 20 on the inner surface side of the left and right side walls 5 of the spacer 1 in FIG. 1 gets over the lower temporary locking protrusion 36 and engages between the upper and lower locking protrusions 36 and 37 to temporarily lock. Then, the claw 20 gets over the upper main locking projection 37 and is finally locked. The hook-like claw 20 has flexibility in the vertical direction, so that temporary locking and main locking can be performed smoothly with a small operating force and securely with a large locking margin. The claw 20 engages with the projections 36 and 37 from the outside.

図４の如く、スペーサ１の本係止状態で、スペーサ１の中央（中央寄り）の一対の係止突壁９がコネクタハウジング２の各切欠孔２７に大きな係止代で係合して、スペーサ１が左右端の係止爪２０（図１）と中央の一対の係止突壁９との計四箇所でコネクタハウジング２にしっかりと係止される。コネクタハウジング２とスペーサ１と端子とでコネクタ３が構成される。   As shown in FIG. 4, when the spacer 1 is fully locked, a pair of locking projection walls 9 at the center (near the center) of the spacer 1 are engaged with the notch holes 27 of the connector housing 2 with a large locking margin. The spacer 1 is firmly locked to the connector housing 2 at a total of four locations, that is, a locking claw 20 (FIG. 1) at the left and right ends and a pair of locking projection walls 9 at the center. The connector housing 2, the spacer 1, and the terminals constitute a connector 3.

従来の図５の中央の係止突起に較べて、本発明のスペーサ１の係止突壁９は前後一対の矩形ブロック状の突起１１で切欠孔２７の幅広部２８に大きな係止代でしっかりと係合するから、係止力が高く、車両等の振動等によっても不意な係止外れが起こらないと共に、スペーサ１の反りが矯正されて、正規な端子係止力が確実に発揮される。   Compared to the conventional central locking projection of FIG. 5, the locking projection wall 9 of the spacer 1 of the present invention is a pair of front and rear rectangular block-shaped projections 11 and is firmly attached to the wide portion 28 of the notch hole 27 with a large locking allowance. Since the engaging force is high, the locking force is high, and the unexpected locking failure does not occur due to the vibration of the vehicle or the like, and the warp of the spacer 1 is corrected, and the normal terminal locking force is reliably exhibited. .

係止突壁９の延長壁１０は切欠孔２７の幅狭部２９に係合し、前後の突起１１は切欠孔２７の幅広部２８に係合し、幅広部２８の上下端と縁２８ｃに当接して係止される。傾斜面１２は、スペーサ挿入時に前後のガイド突壁２９の下端面に摺接しつつ可撓性の係止突壁９を内向きに撓ませて切欠孔２７にスムーズに係合させる。傾斜面１２は幅広部２８内に露出して位置する。   The extension wall 10 of the locking projection wall 9 engages with the narrow portion 29 of the notch hole 27, and the front and rear projections 11 engage with the wide portion 28 of the notch hole 27, and the upper and lower ends of the wide portion 28 and the edge 28c. Abutted and locked. The inclined surface 12 slidably contacts the lower end surface of the front and rear guide projecting walls 29 when the spacer is inserted, and bends the flexible locking projecting wall 9 inward to smoothly engage with the notch hole 27. The inclined surface 12 is exposed and positioned in the wide portion 28.

スペーサ１の係止解除に際しては、一対の係止突壁９の上側の傾斜面１２を二本の指で摘んで内向きに押すことで、あるいは傾斜面１２を治具棒等で下向きに押すことで内向きの分力（押圧力）が発生し、そられにより、各係止突壁９が内向きに撓んで切欠孔２７との係合が解除される。   When releasing the locking of the spacer 1, the upper inclined surface 12 of the pair of locking projection walls 9 is picked with two fingers and pushed inward, or the inclined surface 12 is pushed downward with a jig bar or the like. As a result, an inward component force (pressing force) is generated, whereby each locking projection wall 9 bends inward and the engagement with the cutout hole 27 is released.

その状態でスペーサ１の底板部４の左右両側の操作部２１を下向きに引くことで、スペーサ１の左右端の係止爪２０の本係止が解除され、スペーサ１がコネクタハウジング２のスペーサ挿入孔１８から下向きに引き出されつつ左右端の係止爪２０で仮係止される。仮係止の解除はスペーサ１の鍔部２１を引き下げることで容易に行われる。   In this state, by pulling the operation portions 21 on both the left and right sides of the bottom plate portion 4 of the spacer 1 downward, the main locking of the locking claws 20 on the left and right ends of the spacer 1 is released, and the spacer 1 is inserted into the spacer of the connector housing 2. While being pulled downward from the hole 18, it is temporarily locked by the locking claws 20 at the left and right ends. The temporary locking is easily released by pulling down the flange portion 21 of the spacer 1.

以下に図５〜図７を用いてスペーサ１をコネクタハウジング２に仮係止から本係止させる際の作用を説明する。図５はスペーサ１の仮係止状態、図６はスペーサ１の押し込み途中の状態、図７はスペーサ１の本係止状態をそれぞれ示す。   The operation when the spacer 1 is temporarily locked to the connector housing 2 from the temporary locking will be described below with reference to FIGS. 5 shows a temporarily locked state of the spacer 1, FIG. 6 shows a state in which the spacer 1 is being pushed in, and FIG. 7 shows a fully locked state of the spacer 1.

図５のスペーサ１の仮係止状態で、スペーサ１の左右一対の係止突壁９の上部の傾斜面１２の上端１２ａはコネクタハウジング２の前後各一対のガイド突壁２９の下端面２９ｂの内端に当接し、各係止突壁９は上向きに真直に位置する。係止突壁９の前後の突起１１を含む上端部は、コネクタハウジング２の中央の凹部２３の底壁３０の下側の幅広部３８（切欠孔２７の下部）の外側に隣接して位置する。図５で符号１３はスペーサ１の端子係止用の上側の水平壁、１４は下側の水平壁、２４はコネクタハウジング２のロックアームをそれぞれ示す。   In the temporarily locked state of the spacer 1 of FIG. 5, the upper end 12 a of the upper inclined surface 12 of the pair of left and right locking projection walls 9 of the spacer 1 is the lower end surface 29 b of each pair of front and rear guide projection walls 29 of the connector housing 2. Abutting on the inner end, each locking projection wall 9 is positioned straight upward. The upper end portion including the front and rear projections 11 of the locking projection wall 9 is positioned adjacent to the outside of the lower wide portion 38 (the lower portion of the notch hole 27) of the bottom wall 30 of the concave portion 23 at the center of the connector housing 2. . In FIG. 5, reference numeral 13 denotes an upper horizontal wall for locking terminals of the spacer 1, 14 denotes a lower horizontal wall, and 24 denotes a lock arm of the connector housing 2.

図６の如く、仮係止状態からスペーサ１を押し込むことで、各係止突壁９の上端の傾斜面１２が各ガイド突壁２９の下端面２９ｂの内端を摺接しつつ、各係止突壁９が高さ方向中間部から内向きに撓んで略くの字状に変形し、コネクタハウジング２の切欠孔２７の下側の幅広部３８から外部に突出して、各ガイド突壁２９の内側に位置する。   As shown in FIG. 6, by pushing the spacer 1 from the temporarily locked state, the inclined surface 12 at the upper end of each locking projection wall 9 is in sliding contact with the inner end of the lower end surface 29 b of each guide protruding wall 29. The protruding wall 9 bends inward from the intermediate portion in the height direction and deforms into a substantially U shape, protrudes to the outside from the wide portion 38 below the notch hole 27 of the connector housing 2, and Located inside.

その状態からさらにスペーサ１を押し込むことで、図７の如く、各係止突壁９の前後の突起１１が各ガイド突壁２９を上向きに通過した時点で、各突起１１がガイド突壁２９を乗り越えて弾性的に外向きに復元して、各突起１１が各ガイド突壁２９の上側の各切欠孔２７の幅広部２８に係合する。各突起１１の水平な下面（係止面）１１ｃが各ガイド突壁２８の水平な上面２８ａに当接して、スペーサ１の下方向への抜け出しが阻止され、係止突壁９がガイド突壁２９に係止される。それと同時にスペーサ１の両側の内向きの係止爪（第一係止部）２０（図１）がコネクタハウジング２の外向きの各係止突起（被係止部）３６，３７に本係止される。   When the spacer 1 is further pushed in from this state, as shown in FIG. 7, when the projections 11 on the front and back of each locking projection wall 9 pass upward through the guide projection walls 29, the projections 11 pass through the guide projection walls 29. The projections 11 are elastically restored outwards by overcoming, and the projections 11 engage with the wide portions 28 of the cutout holes 27 on the upper side of the guide projection walls 29. The horizontal lower surface (locking surface) 11c of each protrusion 11 abuts against the horizontal upper surface 28a of each guide protrusion wall 28, and the downward protrusion of the spacer 1 is prevented, so that the locking protrusion wall 9 becomes the guide protrusion wall. 29 is locked. At the same time, inwardly engaging claws (first locking portions) 20 (FIG. 1) on both sides of the spacer 1 are finally locked to the outward locking protrusions (locked portions) 36 and 37 of the connector housing 2. Is done.

このようにスペーサ１の本係止に際して、中央側の左右一対の係止突壁９が内向きに撓み、それと同時に外側の左右一対の爪２０が外向きに撓むことで、すなわち中央と外側の各係止部材９，２０が相互に逆向きに撓むことで、スペーサ１の反り（スペーサ１の左右両側が下向きに反ること）が防止され、寧ろスペーサ１の左右両側が上向きに反る傾向となるので（この場合でも係止突壁９は中央寄りに位置するので反りの影響は受けない）、外側の爪２０と各係止突起３６，３７との係止力の低下が防止され、且つ中央の係止突壁９の各突起１１とガイド突壁２９とが大きな係止代すなわち大きな係止力でしっかりと確実に係止される。   In this way, when the spacer 1 is fully locked, the pair of left and right locking projection walls 9 on the center side bend inward, and at the same time the pair of outer left and right claws 20 bend outward, that is, the center and the outside. Since each of the locking members 9 and 20 bends in opposite directions, the spacer 1 is prevented from warping (the left and right sides of the spacer 1 are warped downward), and rather the left and right sides of the spacer 1 are warped upward. (In this case as well, the locking projection wall 9 is located closer to the center and is not affected by the warp), so that a reduction in the locking force between the outer claw 20 and the locking projections 36 and 37 is prevented. In addition, the projections 11 of the central locking projection wall 9 and the guide projection wall 29 are securely and reliably locked with a large locking allowance, that is, a large locking force.

なお、上記実施形態においては、スペーサ１の左右端の係止爪２０に対してコネクタハウジング２に仮係止突起３６と本係止突起３７を設けたが、例えば本係止突起３７を排除し、中央の係止突壁９のみ本係止を行わせることも可能である。また、仮係止突起３６や係止爪２０も排除して中央の係止突壁９で本係止のみ行わせることも可能である。この場合、スペーサ未挿入で雌端子の挿入を行い、スペーサ１の挿入で雌端子を係止する。   In the above embodiment, the connector housing 2 is provided with the temporary locking projections 36 and the final locking projections 37 with respect to the locking claws 20 at the left and right ends of the spacer 1. It is also possible to perform the main locking only on the central locking projection wall 9. It is also possible to eliminate the temporary locking projections 36 and the locking claws 20 and perform only the main locking with the central locking projection wall 9. In this case, the female terminal is inserted without inserting the spacer, and the female terminal is locked by inserting the spacer 1.

また、上記実施形態においては、コネクタハウジング２の上部中央の凹部２３内にロックアーム２４を設けたが、例えばロックアーム２４に代えてアース用等の他の端子（図示せず）を収容する端子収容室（図示せず）と、この端子収容室を覆う壁部（図示せず）を設けることも可能である。   Moreover, in the said embodiment, although the lock arm 24 was provided in the recessed part 23 of the upper center of the connector housing 2, it replaces with the lock arm 24 and the terminal which accommodates other terminals (not shown) etc. for earth | grounds, for example It is also possible to provide a storage chamber (not shown) and a wall (not shown) that covers the terminal storage chamber.

However, instead of the front and rear pair, one projection 11 is provided at the front or rear, and a pair of front and rear guide projection walls 29 on the connector housing 2 side. It is also possible to provide one before or after instead of a pair of front and rear.

また、上記実施形態においては、係止突壁９の上端に外向きの傾斜面１２を設けたが、例えばコネクタハウジング２のガイド突壁２９の下端にも内向きの傾斜面（図示せず）を設け、あるいはガイド突壁２９の下端に内向きの傾斜面を設け、係止突壁９の傾斜面１２は排除することも可能である。   Further, in the above embodiment, the outwardly inclined surface 12 is provided at the upper end of the locking protruding wall 9. However, for example, an inwardly inclined surface (not shown) is also formed at the lower end of the guide protruding wall 29 of the connector housing 2. Alternatively, an inwardly inclined surface may be provided at the lower end of the guide protruding wall 29, and the inclined surface 12 of the locking protruding wall 9 may be eliminated.

また、上記実施形態においては、ガイド突壁２９を切欠孔２７の前後両側に設けたが、例えば切欠孔２７の幅方向中央にガイド突壁（図示せず）を外側から水平に突出させ、係止突壁９に突起１１ではなく幅方向中央の孔部（図示せず）を設け、ガイド突壁に係止突壁９の上端の傾斜面１２を摺接させつつ係止突壁９を内向きに撓ませ、復元時に孔部（図示せず）にガイド突壁（図示せず）を進入係合させるようにすることも可能である。   In the above embodiment, the guide protrusion walls 29 are provided on both the front and rear sides of the notch hole 27. For example, a guide protrusion wall (not shown) is projected horizontally from the outside in the center of the notch hole 27 in the width direction.
