Description

本発明は、コネクタに関するものである。 The present invention relates to a connector.

図１５及び図１６は、コネクタの従来例を示したものである。
このコネクタ１は、下記特許文献１に開示されたもので、雌型端子金具３を収容する端子収容部５が設けられたコネクタハウジング７内に、雌型端子金具３を抜け止めするランス９が一体形成されている。 15 and 16 show a conventional example of a connector.
This connector 1 is disclosed in Patent Document 1 below, and a lance 9 that prevents the female terminal fitting 3 from coming off is provided in a connector housing 7 provided with a terminal accommodating portion 5 that accommodates the female terminal fitting 3. It is integrally formed.

ランス９は、雌型端子金具３の挿入方向に沿って延設された弾性片９ａ上に、端子収容部５内に突出する係止突起９ｂを設けたもので、雌型端子金具３に設けられた係止溝に係止突起９ｂが係合することで、雌型端子金具３の抜けを防止する。 The lance 9 is provided with a locking projection 9b protruding into the terminal accommodating portion 5 on an elastic piece 9a extending along the insertion direction of the female terminal fitting 3, and is provided on the female terminal fitting 3. The engagement protrusion 9b engages with the formed engagement groove, thereby preventing the female terminal fitting 3 from coming off.

また、従来のコネクタ１は、コネクタハウジング７には、保護部材１１が装着されている。この保護部材１１は、コネクタハウジング７に仮係止された図１５の状態ではランス９の撓み変位を規制しないが、コネクタハウジング７に本係止された図１６の状態ではランス９の係合解除方向への撓み変位を拘束する二重係止手段として機能して、ランス９による雌型端子金具３の固定を確実にする。 In the conventional connector 1, a protective member 11 is attached to the connector housing 7. The protective member 11 does not restrict the bending displacement of the lance 9 in the state of FIG. 15 temporarily locked to the connector housing 7, but is disengaged from the lance 9 in the state of FIG. 16 permanently locked to the connector housing 7. It functions as a double locking means for restraining the deflection displacement in the direction, and the fixing of the female terminal fitting 3 by the lance 9 is ensured.

以上のコネクタハウジング７は、樹脂の射出成形により一体形成される。 The connector housing 7 described above is integrally formed by resin injection molding.

特開２００６−１００２２７号公報JP 2006-100227 A

ところが、上記のコネクタハウジング７の場合、成形金型の型抜き構造等から、弾性変位するランス９の周囲には、比較的に大きな隙間Ｓ１を確保しなければならない。 However, in the case of the connector housing 7 described above, a relatively large gap S1 must be secured around the lance 9 that is elastically displaced due to the die-cutting structure of the molding die.

また、ランス９により係止されている雌型端子金具３を抜き出す際には、ランス９を係合解除方向に撓ませる必要がある。また、ランス９の係合解除時にはランス９上の係止突起９ｂの突出量の分だけ、ランス９を大きく撓ませる必要がある。そのため、ランス９を係合解除方向に撓ませる端子抜き用治具を差し込む抜き治具用穴１３を、比較的に大きな口径で端子収容部５に隣接して設けなければならない。 Further, when extracting the female terminal fitting 3 locked by the lance 9, it is necessary to bend the lance 9 in the disengagement direction. Further, when the lance 9 is disengaged, it is necessary to bend the lance 9 greatly by the amount of protrusion of the locking projection 9b on the lance 9. Therefore, it is necessary to provide an extraction jig hole 13 for inserting a terminal extraction jig for bending the lance 9 in the disengagement direction with a relatively large diameter adjacent to the terminal accommodating portion 5.

そして、上記の隙間Ｓ１や抜き治具用穴１３が大きいために、コネクタ１を相手側コネクタに嵌合接続する際に、相手側コネクタの雄型端子金具の先端が上記隙間Ｓ１や抜き治具用穴１３に誤挿入されて、雄型端子金具の曲げ変形という不都合が発生するおそれがあった。 Since the gap S1 and the extraction jig hole 13 are large, when the connector 1 is fitted and connected to the mating connector, the tip of the male terminal fitting of the mating connector is connected to the gap S1 or the extraction jig. There is a possibility that the inconvenience of bending deformation of the male terminal fitting may occur due to being erroneously inserted into the service hole 13.

また、ランス９を一体形成するために、コネクタハウジング７の成形金型の構造が複雑化するという問題もあった。 Further, since the lance 9 is integrally formed, there is a problem that the structure of the molding die of the connector housing 7 is complicated.

そこで、本発明の目的は上記課題を解消することに係り、相手コネクタとの嵌合接続時に相手コネクタの雄型端子金具が誤挿入により変形するという問題が発生せず、確実に相手コネクタとの接続を完了させることができ、また、端子収容部を有するコネクタハウジングの成形金型の構造を単純化することもできるコネクタを提供することにある。 Therefore, the object of the present invention is to solve the above-mentioned problems, and the problem that the male terminal fitting of the mating connector is deformed by erroneous insertion at the time of mating connection with the mating connector does not occur. An object of the present invention is to provide a connector capable of completing the connection and simplifying the structure of the molding die of the connector housing having the terminal accommodating portion.

本発明の前述した目的は、下記の構成により達成される。

前記インナーハウジングの前半部を前記アウターハウジングに挿入した仮係止位置と前記インナーハウジングの略全体を前記アウターハウジングに挿入した本係止位置との２つの位置で前記インナーハウジングと前記アウターハウジングとを結合可能なハウジング係止手段と、
を備えたコネクタであって、
前記端子収容部には、収容部下部壁の前半側に***形成されて前記雌型端子金具の抜け止め用の係止溝と係合することで前記雌型端子金具の挿抜方向の移動を規制する抜け止め突起と、前記雌型端子金具の前記端子収容部への挿入時に前記雌型端子金具の前端部が前記抜け止め突起に干渉しないように、前記雌型端子金具の側部に突設された摺動突起を案内することで前記雌型端子金具の前半部を前記収容部下部壁から浮き上がらせる傾斜案内部と、前記収容部下部壁に対向する収容部上部壁の前半部を切除した形態で設けられて前記傾斜案内部による誘導によって前記収容部下部壁から浮き上がった前記雌型端子金具の前半部が挿通可能な開口部と、が備えられ、

(1) an outer housing;
An inner housing that has a terminal accommodating portion that accommodates a female terminal fitting and is inserted into and mounted on the outer housing;
The inner housing and the outer housing are connected at two positions, a temporary locking position where the front half of the inner housing is inserted into the outer housing and a final locking position where substantially the entire inner housing is inserted into the outer housing. A connectable housing locking means;
A connector with
The terminal receiving portion is formed to be raised on the front half side of the lower wall of the receiving portion and engages with a locking groove for retaining the female terminal fitting, thereby restricting movement of the female terminal fitting in the insertion / extraction direction. A retaining projection that protrudes from the side of the female terminal fitting so that the front end of the female terminal fitting does not interfere with the retaining projection when the female terminal fitting is inserted into the terminal accommodating portion. An inclined guide portion that lifts the front half of the female terminal fitting from the lower wall of the housing portion by guiding the sliding protrusion formed, and a front half portion of the upper wall of the housing portion that faces the housing lower wall are cut off. An opening through which the front half of the female terminal fitting, which is provided in a form and is lifted from the lower wall of the housing portion by guidance by the inclined guide portion, can be inserted;
The outer housing is provided with an elastic pressing piece extending along the insertion direction of the inner housing at a position facing the opening of the inner housing at the temporary locking position,
When the front end portion of the female terminal fitting inserted into the terminal housing portion of the inner housing at the temporary locking position protrudes from the opening portion by induction by the inclined guide portion, the elastic holding piece is moved to the front end of the female terminal fitting. The connector is pushed back to the housing lower wall side so that the locking groove of the female terminal fitting is locked by the retaining protrusion.

（２）前記アウターハウジングには、前記インナーハウジングが本係止位置に移動したときに前記開口部を覆う端子押え壁が前記インナーハウジングの挿入方向に沿って固定装備され、
前記端子押え壁が、前記端子収容部に収容保持されている前記雌型端子金具の前記収容部下部壁からの浮き上がりを押さえて、前記雌型端子金具が前記抜け止め突起により係止されている状態を維持することを特徴とする上記（１）に記載のコネクタ。 (2) The outer housing is fixedly equipped with a terminal pressing wall that covers the opening when the inner housing moves to the final locking position along the insertion direction of the inner housing,
The terminal holding wall holds the female terminal fitting held and held in the terminal containing portion from the lower wall of the containing portion, and the female terminal fitting is locked by the retaining protrusion. The connector as described in (1) above, wherein the state is maintained.

（３）前記端子収容部の収容部側部壁には、前記抜け止め突起と前記係合溝とが係合するときに、前記摺動突起と係合して前記雌型端子金具の抜け方向の移動を規制する端子係止溝が備えられたことを特徴とする上記（１）又は（２）に記載のコネクタ。 (3) When the retaining projection and the engaging groove are engaged with the accommodating portion side wall of the terminal accommodating portion, the sliding direction of the female terminal fitting is engaged with the sliding projection. The connector according to (1) or (2) above, further comprising a terminal locking groove for restricting movement of the connector.

上記（１）の構成によれば、インナーハウジングがハウジング係止手段により仮係止位置に係止されている状態で、インナーハウジングの端子収容部に雌型端子金具が挿入される。雌型端子金具の挿入途中で雌型端子金具が傾斜案内部に乗り上げると、この傾斜案内部による誘導によって、雌型端子金具の前半部は収容部下部壁から浮き上がり、雌型端子金具の前端部の上部が開口部から上方に突出し、アウターハウジングの弾性押え片に当接する。 According to the configuration of (1) above, the female terminal fitting is inserted into the terminal accommodating portion of the inner housing while the inner housing is locked at the temporary locking position by the housing locking means. When the female terminal fitting rides on the inclined guide part during insertion of the female terminal fitting, the front half of the female terminal fitting is lifted from the lower wall of the housing part by the guidance of the inclined guiding part, and the front end part of the female terminal fitting is inserted. The upper part protrudes upward from the opening and comes into contact with the elastic pressing piece of the outer housing.

更に、雌型端子金具の挿入を行うと、雌型端子金具の前端部が弾性押え片により雌型端子金具の前半部が収容部下部壁側に押し戻されて、雌型端子金具の係止溝が抜け止め突起により係止された状態になる。 Further, when the female terminal fitting is inserted, the front end of the female terminal fitting is pushed back to the lower wall side of the housing portion by the elastic pressing piece, so that the locking groove of the female terminal fitting is inserted. Is locked by the retaining protrusion.

そして、上記（１）の構成によれば、雌型端子金具を抜け止めするインナーハウジングの抜け止め突起は、雌型端子金具の挿入方向及びその直交方向に対して弾性変位しない剛体構造の隔壁である収容部下部壁に設けているため、雌型端子金具の挿入方向に直交する方向に弾性変位するランスによって雌型端子金具を抜け止めしていた従来のコネクタハウジングと比較すると、成形金型の型抜き構造等のための隙間を大きく設ける必要がない。 According to the configuration of (1), the retaining protrusion of the inner housing that prevents the female terminal fitting from being detached is a partition wall having a rigid structure that is not elastically displaced with respect to the insertion direction of the female terminal fitting and the orthogonal direction thereof. Since it is provided on the lower wall of the housing part, compared with the conventional connector housing in which the female terminal fitting is prevented from being detached by a lance that is elastically displaced in the direction perpendicular to the insertion direction of the female terminal fitting, There is no need to provide a large gap for a die cutting structure or the like.

また、雌型端子金具の端子収容部への装着は、仮係止位置のインナーハウジングに対して行う構成で、インナーハウジングをアウターハウジングから引き抜くと、傾斜案内部から雌型端子金具に作用する付勢力で、抜け止め突起と雌型端子金具との係合が簡単に解除可能になるため、端子抜き用治具を差し込む抜き治具用穴を比較的に大きな口径で端子収容部に隣接して設ける必要も無くなる。 In addition, the female terminal fitting is attached to the terminal accommodating portion with respect to the inner housing at the temporary locking position. When the inner housing is pulled out from the outer housing, the female terminal fitting acts on the female terminal fitting from the inclined guide portion. The engagement between the retaining protrusion and the female terminal fitting can be easily released by force, so the hole for the removal tool for inserting the removal tool for the terminal is adjacent to the terminal accommodating part with a relatively large diameter. There is no need to provide it.

従って、端子収容部の周囲等に形成される隙間や治具用穴の縮小を図ることができ、相手コネクタとの嵌合接続時に相手コネクタの雄型端子金具が端子収容部の周囲の隙間や治具用穴への誤挿入により変形するという問題を回避して、確実に相手コネクタとの接続を完了させることができる。 Therefore, it is possible to reduce the gaps and jig holes formed around the terminal accommodating portion and the like, and the male terminal fitting of the mating connector is connected to the clearance around the terminal accommodating portion and the mating connector. The problem of deformation due to erroneous insertion into the jig hole can be avoided, and the connection with the mating connector can be reliably completed.

そして、インナーハウジングには雌型端子金具の挿入方向に直交する方向に弾性変位するランスが不要になること、更に、雌型端子金具を抜け止め突起に係合させるためにアウターハウジングに装備した弾性押え片も前記インナーハウジングの挿入方向に沿って延出した単純な板状構造で良いことから、これらのインナーハウジングやアウターハウジングでは、成形金型の型抜きが困難になることがない。従って、ランスによって雌型端子金具を抜け止めしていた従来のコネクタハウジングと比較すると、各ハウジングの成形金型の型抜きが容易になり、コネクタハウジングの成形金型の構造を単純化することもできる。 In addition, the inner housing does not require a lance that is elastically displaced in a direction perpendicular to the insertion direction of the female terminal fitting, and further, an elastic provided in the outer housing for engaging the female terminal fitting with the retaining protrusion. Since the pressing piece may be a simple plate-like structure extending along the insertion direction of the inner housing, it is not difficult to remove the mold from these inner housing and outer housing. Therefore, in comparison with the conventional connector housing in which the female terminal fitting is prevented from being removed by the lance, it becomes easy to remove the molding die of each housing, and the structure of the molding die of the connector housing can be simplified. it can.

なお、アウターハウジングに仮係止位置で結合されているインナーハウジングの端子収容部に雌型端子金具の挿入作業を行った場合に、雌型端子金具が正常に端子収容部内の抜け止め突起に係止される前に、雌型端子金具の挿入操作を終えると、雌型端子金具は前半部の上端が開口部に突出した不完全挿入状態で残留する。その状態のままインナーハウジングをアウターハウジング内に押し込むと、不完全挿入状態の雌型端子金具が弾性押え片との干渉によりインナーハウジングの後方に押し出されるため、視認により、不完全挿入状態の発生を容易に検知することができ、雌型端子金具の不完全挿入の防止に有効である。 When the female terminal fitting is inserted into the terminal housing portion of the inner housing that is joined to the outer housing at the temporary locking position, the female terminal fitting is normally engaged with the retaining protrusion in the terminal housing portion. When the insertion operation of the female terminal fitting is finished before it is stopped, the female terminal fitting remains in an incompletely inserted state in which the upper end of the front half projects into the opening. If the inner housing is pushed into the outer housing in this state, the incompletely inserted female terminal fitting will be pushed to the rear of the inner housing due to interference with the elastic presser piece. It can be easily detected and is effective in preventing incomplete insertion of the female terminal fitting.

また、上記（２）の構成によれば、雌型端子金具が端子収容部の抜け止め突起により係止された正常嵌合状態で、インナーハウジングをアウターハウジング内に更に挿入して、インナーハウジングの略全体を前記アウターハウジングに挿入した状態にすると、インナーハウジングが本係止位置でアウターハウジングに結合された本係止状態になる。 Further, according to the configuration of (2), the inner housing is further inserted into the outer housing in a normal fitting state where the female terminal fitting is locked by the retaining protrusion of the terminal accommodating portion. When the entire housing is inserted into the outer housing, the inner housing is in a final locking state where the inner housing is coupled to the outer housing at the final locking position.

この本係止状態では、アウターハウジングに装備された端子押え壁が、インナーハウジングの端子収容部の開口部を覆って、端子収容部に収容保持されている雌型端子金具の収容部下部壁からの浮き上がりを規制し、雌型端子金具が抜け止め突起により係止されている状態を維持する。 In this fully locked state, the terminal retainer wall provided in the outer housing covers the opening of the terminal accommodating portion of the inner housing, and from the accommodating portion lower wall of the female terminal fitting that is accommodated and held in the terminal accommodating portion. And the state where the female terminal fitting is locked by the retaining protrusion is maintained.

即ち、アウターハウジングの端子押え壁は、端子収容部の抜け止め突起が雌型端子金具に係合した状態を維持する二重係止手段として機能し、雌型端子金具に対する抜け止め性能を確実なものにする。 In other words, the terminal retainer wall of the outer housing functions as a double locking means that maintains the state in which the retaining protrusion of the terminal accommodating portion is engaged with the female terminal fitting, and ensures the retaining performance against the female terminal fitting. Make things.

そして、二重係止手段として機能するアウターハウジングの端子押え壁は、インナーハウジングの挿入方向に沿って固定装備された剛体構造の隔壁でよいため、当該アウターハウジングの成形金型の型抜きを困難にすることもなく、アウターハウジングの成形金型の構造の単純化に適している。 Further, since the terminal holding wall of the outer housing that functions as a double locking means may be a rigid partition wall that is fixedly installed along the insertion direction of the inner housing, it is difficult to remove the molding die of the outer housing. Therefore, it is suitable for simplifying the structure of the molding die for the outer housing.

そして、上記(３)の構成によれば、端子収容部の底部の抜け止め突起だけでなく、収容部側部壁の端子係止溝も、雌型端子金具の抜け方向の移動を規制する手段として機能するため、雌型端子金具の抜け止めをより強固にすることができる。 According to the configuration of the above (3), not only the retaining protrusion on the bottom of the terminal accommodating portion but also the terminal locking groove on the side wall of the accommodating portion regulates the movement of the female terminal fitting in the removing direction. Therefore, the female terminal fitting can be more securely prevented from coming off.

また、インナーハウジング側の端子係止溝は、例えば、端子収容部の収容部側部壁の端部に切欠溝として形成することで、成形金型の型抜き性を低下させることもない。 Further, the terminal locking groove on the inner housing side is formed as a notch groove in the end portion of the accommodating portion side wall of the terminal accommodating portion, for example, so that the mold release property of the molding die is not deteriorated.

本発明によるコネクタによれば、端子収容部の周囲等に形成される隙間や治具用穴の縮小を図ることができ、相手コネクタとの嵌合接続時に相手コネクタの雄型端子金具が端子収容部の周囲の隙間や治具用穴への誤挿入により変形するという問題を回避して、確実に相手コネクタとの接続を完了させることができる。 According to the connector of the present invention, it is possible to reduce gaps and jig holes formed around the terminal accommodating portion and the like, and the male terminal fitting of the mating connector is accommodated in the terminal housing during the mating connection with the mating connector. It is possible to avoid the problem of deformation due to erroneous insertion into the gap around the part or the jig hole, and to reliably complete the connection with the mating connector.

また、ランスによって雌型端子金具を抜け止めしていた従来のコネクタハウジングと比較すると、アウターハウジング及びインナーハウジングのいずれの場合も、成形金型の型抜きが容易になるため、コネクタハウジングの成形金型の構造を単純化することもできる。 In addition, in comparison with the conventional connector housing in which the female terminal fitting is prevented from being removed by the lance, the mold of the connector housing can be easily removed in both the outer housing and the inner housing. You can also simplify the type structure.

The inner surfaces of 37a and 37a are formed from the rear end of the outer housing 33 to the center of the housing along the insertion direction of the inner housing 37.

第１係止突起４７と第２係止突起４９とは、ガイド溝４３に嵌合するように、インナーハウジング３７の側面３７ａに同じ高さに設けられている。第１係止突起４７はインナーハウジング３７の先端付近に突設されていて、第２係止突起４９はハウジングの略中央に突設されている。 The first locking protrusion 47 and the second locking protrusion 49 are provided at the same height on the side surface 37 a of the inner housing 37 so as to fit into the guide groove 43. The first locking protrusion 47 protrudes near the tip of the inner housing 37, and the second locking protrusion 49 protrudes substantially at the center of the housing.

図１１に示すように、インナーハウジング３７を、その前半部をアウターハウジング３３に挿入した仮係止位置に位置させると、第１係止突起４７がガイド溝４３の終端に係合することで、インナーハウジング３７とアウターハウジング３３とが仮の結合状態である仮係止状態となる。 As shown in FIG. 11, when the inner housing 37 is positioned at the temporary locking position where the front half of the inner housing 37 is inserted into the outer housing 33, the first locking projection 47 is engaged with the terminal end of the guide groove 43, The inner housing 37 and the outer housing 33 are in a temporarily locked state, which is a temporarily joined state.

仮係止状態から、更にインナーハウジング３７をアウターハウジング３３内に押し込むと、図１４に示すようにインナーハウジング３７の略全体をアウターハウジング３３に挿入した全挿入状態となる。このときのインナーハウジング３７の位置が本係止位置である。このときは、インナーハウジング３７上の第１係止突起４７がアウターハウジング３３の係止凹部４５に係合し、第２係止突起４９がガイド溝４３の終端に係合して、インナーハウジング３７が完全にアウターハウジング３３に装着された状態でアウターハウジング３３に結合された本係止状態となる。 When the inner housing 37 is further pushed into the outer housing 33 from the temporarily locked state, almost the entire inner housing 37 is inserted into the outer housing 33 as shown in FIG. The position of the inner housing 37 at this time is the final locking position. At this time, the first locking projection 47 on the inner housing 37 is engaged with the locking recess 45 of the outer housing 33, and the second locking projection 49 is engaged with the terminal end of the guide groove 43, so that the inner housing 37 is engaged. Is fully engaged with the outer housing 33 in a state of being completely mounted on the outer housing 33.

本実施形態の場合、インナーハウジング３７には、図１０に示すように、上下２段に、端子収容部３５が装備されている。そして、各端子収容部３５には、抜け止め突起５１と、傾斜案内部５３と、開口部５５と、端子係止溝５７とが設けられている。 In the case of this embodiment, as shown in FIG. 10, the inner housing 37 is equipped with terminal accommodating portions 35 in two upper and lower stages. Each terminal accommodating portion 35 is provided with a retaining protrusion 51, an inclined guide portion 53, an opening 55, and a terminal locking groove 57.

抜け止め突起５１は、端子収容部３５内に突出するように、収容部下部壁３５ａの前半側に***形成された突起で、図５に示した雌型端子金具２３の抜け止め用の係止溝２８と係合することで雌型端子金具２３の挿抜方向の移動を規制する。 The retaining projection 51 is a projection that is raised on the front half side of the housing lower wall 35a so as to project into the terminal housing portion 35, and is a latch for retaining the female terminal fitting 23 shown in FIG. Engaging with the groove 28 restricts the movement of the female terminal fitting 23 in the insertion / extraction direction.

傾斜案内部５３は、雌型端子金具２３の端子収容部３５への挿入時に、雌型端子金具２３の前端部が抜け止め突起５１に干渉しないように、雌型端子金具２３の前半部を収容部下部壁３５ａから浮き上がらせる傾斜面（スロープ）である。この傾斜案内部５３は、図５に示した雌型端子金具２３の摺動突起３１が乗り上げるように、収容部側部壁３５ｂに設けられている。 The inclined guide portion 53 accommodates the front half of the female terminal fitting 23 so that the front end of the female terminal fitting 23 does not interfere with the retaining protrusion 51 when the female terminal fitting 23 is inserted into the terminal accommodating portion 35. This is an inclined surface (slope) that rises from the lower part wall 35a. The inclined guide portion 53 is provided on the accommodating portion side wall 35b so that the sliding protrusion 31 of the female terminal fitting 23 shown in FIG.

開口部５５は、収容部下部壁３５ａに対向する収容部上部壁３５ｃの前半部を切除した形態で設けられて、端子収容部３５を上方に開放している。この開口部５５は、傾斜案内部５３による誘導によって収容部下部壁３５ａから浮き上がった雌型端子金具２３の前半部を上方に挿通可能にしている。 The opening 55 is provided in a form in which the front half of the housing upper wall 35c facing the housing lower wall 35a is cut out, and opens the terminal housing 35 upward. The opening 55 allows the front half of the female terminal fitting 23 that has been lifted from the housing lower wall 35 a by the guidance of the inclined guide 53 to be inserted upward.

端子係止溝５７は、図６及び図１０に示すように、端子収容部３５の収容部側部壁３５ｂの前端部に、切欠溝として形成されている。この端子係止溝５７は、仮係止状態のインナーハウジング３７の端子収容部３５に雌型端子金具２３が挿入されて、雌型端子金具２３の係止溝２８と端子収容部３５内の抜け止め突起５１とが係合するときに、雌型端子金具２３の側部に突設された摺動突起３１と係合して、雌型端子金具２３の抜け方向の移動を規制する。 As shown in FIGS. 6 and 10, the terminal locking groove 57 is formed as a notch groove in the front end portion of the accommodating portion side wall 35 b of the terminal accommodating portion 35. The terminal locking groove 57 is formed by inserting the female terminal fitting 23 into the terminal receiving portion 35 of the inner housing 37 in the temporarily locked state, and removing the locking groove 28 of the female terminal fitting 23 and the terminal receiving portion 35. When the locking projection 51 is engaged, it engages with the sliding projection 31 projecting from the side of the female terminal fitting 23 to restrict the movement of the female terminal fitting 23 in the removal direction.

一方、アウターハウジング３３には、図９及び図１１に示すように、仮係止位置のインナーハウジング３７の開口部５５と対向する位置に、インナーハウジング３７の挿入方向（図９の矢印Ａ方向）に沿って延出した弾性押え片６１が備えられている。 On the other hand, in the outer housing 33, as shown in FIGS. 9 and 11, the insertion direction of the inner housing 37 (in the direction of arrow A in FIG. 9) at a position facing the opening 55 of the inner housing 37 at the temporary locking position. An elastic presser piece 61 extending along the line is provided.

弾性押え片６１は、インナーハウジング３７の挿入方向と直交する方向に撓み変形する板ばね状になっている。 The elastic pressing piece 61 has a leaf spring shape that bends and deforms in a direction orthogonal to the insertion direction of the inner housing 37.

アウターハウジング３３に仮係止状態のインナーハウジング３７の端子収容部３５に雌型端子金具２３を挿入して行くと、図１１に示すように、雌型端子金具２３の摺動突起３１が傾斜案内部５３の始端に乗り上げる。そして、更に雌型端子金具２３を挿入すると、図１２に示すように、摺動突起３１が傾斜案内部５３を上るに従って、雌型端子金具２３の前半部が収容部下部壁３５ａから浮き上がり、雌型端子金具２３の前端が開口部５５から突出して、弾性押え片６１に当接する。 When the female terminal fitting 23 is inserted into the terminal housing portion 35 of the inner housing 37 that is temporarily locked to the outer housing 33, the sliding protrusion 31 of the female terminal fitting 23 is inclined and guided as shown in FIG. Get on the beginning of part 53. When the female terminal fitting 23 is further inserted, as shown in FIG. 12, the front half of the female terminal fitting 23 is lifted from the housing lower wall 35a as the sliding protrusion 31 rises up the inclined guide portion 53, The front end of the mold terminal fitting 23 protrudes from the opening 55 and comes into contact with the elastic holding piece 61.

その状態で、雌型端子金具２３を更に挿入すると、弾性押え片６１は、当接した雌型端子金具２３の前端部を収容部下部壁３５ａ側に押し戻して、図１３に示すように、雌型端子金具２３の係止溝２８が抜け止め突起５１により係止された状態にする。 In this state, when the female terminal fitting 23 is further inserted, the elastic holding piece 61 pushes the front end portion of the contacted female terminal fitting 23 back toward the accommodating portion lower wall 35a, and as shown in FIG. The locking groove 28 of the mold terminal fitting 23 is locked by the retaining protrusion 51.

また、本実施形態の場合、アウターハウジング３３には、図９に示すように、弾性押え片６１の基端側から、インナーハウジング３７の挿入方向に沿ってアウターハウジング３３の先端側に延びる端子押え壁６３が固定装備されている。 In the case of this embodiment, the outer housing 33 has a terminal retainer extending from the proximal end side of the elastic retainer piece 61 to the distal end side of the outer housing 33 along the insertion direction of the inner housing 37, as shown in FIG. A wall 63 is fixedly equipped.

この端子押え壁６３は、図１４に示したように、インナーハウジング３７が本係止状態となる本係止位置に移動したときに開口部５５を覆って、端子収容部３５に収容保持されている雌型端子金具２３の収容部下部壁３５ａからの浮き上がりを押さえる。これにより、端子押え壁６３は、雌型端子金具２３が抜け止め突起５１により係止されている状態を維持する二重係止手段として機能する。 As shown in FIG. 14, the terminal pressing wall 63 covers the opening 55 when the inner housing 37 moves to the final locking position where the inner housing 37 is in the final locking state, and is accommodated and held in the terminal accommodating portion 35. The floating of the female terminal fitting 23 from the accommodating portion lower wall 35a is suppressed. Thereby, the terminal pressing wall 63 functions as double locking means for maintaining the state in which the female terminal fitting 23 is locked by the retaining protrusion 51.

以上に説明した一実施形態のコネクタ２１では、インナーハウジング３７がハウジング係止手段により仮係止位置に係止されている状態（仮係止状態）で、インナーハウジング３７の端子収容部３５に雌型端子金具２３が挿入される。雌型端子金具２３の挿入途中で雌型端子金具２３の摺動突起３１が傾斜案内部５３に乗り上げると、この傾斜案内部５３による誘導によって、雌型端子金具２３の前半部は収容部下部壁３５ａから浮き上がり、雌型端子金具２３の前端部の上部が開口部５５から上方に突出し、アウターハウジング３３の弾性押え片６１に当接する。 In the connector 21 according to the embodiment described above, the terminal housing portion 35 of the inner housing 37 is female with the inner housing 37 locked in the temporary locking position by the housing locking means (temporary locking state). The mold terminal fitting 23 is inserted. When the sliding projection 31 of the female terminal fitting 23 rides on the inclined guide portion 53 during the insertion of the female terminal fitting 23, the front half of the female terminal fitting 23 is guided by the inclined guide portion 53 so that the lower wall of the housing portion is accommodated. The upper part of the front end of the female terminal fitting 23 protrudes upward from the opening 55 and comes into contact with the elastic pressing piece 61 of the outer housing 33.

更に、雌型端子金具２３の挿入を行うと、雌型端子金具２３の前端部が弾性押え片６１により雌型端子金具２３の前半部が収容部下部壁３５ａ側に押し戻されて、雌型端子金具２３の係止溝２８が抜け止め突起５１により係止された状態になる。 Further, when the female terminal fitting 23 is inserted, the front end portion of the female terminal fitting 23 is pushed back by the elastic pressing piece 61 to the housing lower wall 35a side, and the female terminal fitting 23 is pushed back. The locking groove 28 of the metal fitting 23 is locked by the retaining protrusion 51.

そして、上記一実施形態のコネクタ２１の構成によれば、雌型端子金具２３を抜け止めするインナーハウジング３７の抜け止め突起５１は、雌型端子金具２３の挿入方向及びその直交方向に対して弾性変位しない剛体構造の隔壁である収容部下部壁３５ａに設けられているため、雌型端子金具の挿入方向に直交する方向に弾性変位するランスによって雌型端子金具を抜け止めしていた従来のコネクタハウジングと比較すると、成形金型の型抜き構造等のための隙間を大きく設ける必要がない。 According to the configuration of the connector 21 of the above embodiment, the retaining protrusion 51 of the inner housing 37 that retains the female terminal fitting 23 is elastic with respect to the insertion direction of the female terminal fitting 23 and the orthogonal direction thereof. A conventional connector in which the female terminal fitting is retained by a lance that is elastically displaced in a direction perpendicular to the insertion direction of the female terminal fitting because it is provided on the housing lower wall 35a that is a rigid structure partition wall that does not displace. Compared to the housing, there is no need to provide a large gap for the die-cutting structure of the molding die.

また、雌型端子金具２３の端子収容部３５への装着は、仮係止状態のインナーハウジング３７に対して行う構成であり、インナーハウジング３７をアウターハウジング３３から引き抜くと、傾斜案内部５３から雌型端子金具２３に作用する付勢力で、抜け止め突起５１と雌型端子金具２３との係合が簡単に解除可能になるため、端子抜き用治具を差し込む抜き治具用穴を比較的に大きな口径で端子収容部３５に隣接して設ける必要も無くなる。 In addition, the female terminal fitting 23 is attached to the terminal accommodating portion 35 with respect to the inner housing 37 in a temporarily locked state. When the inner housing 37 is pulled out from the outer housing 33, the female guide fitting 23 is removed from the inclined guide portion 53. Since the engagement between the retaining projection 51 and the female terminal fitting 23 can be easily released by the urging force acting on the mold terminal fitting 23, the removal jig hole for inserting the terminal removal jig is relatively It is not necessary to provide a large aperture adjacent to the terminal accommodating portion 35.

従って、端子収容部３５の周囲等に形成される隙間や治具用穴の縮小を図ることができ、相手コネクタとの嵌合接続時に相手コネクタの雄型端子金具が端子収容部３５の周囲の隙間や治具用穴への誤挿入により変形するという問題を回避して、確実に相手コネクタとの接続を完了させることができる。 Accordingly, the gaps and jig holes formed around the terminal accommodating portion 35 can be reduced, and the male terminal fitting of the mating connector can be disposed around the terminal accommodating portion 35 during the mating connection with the mating connector. The problem of deformation due to erroneous insertion into the gap or the jig hole can be avoided, and the connection with the mating connector can be reliably completed.

そして、インナーハウジング３７には雌型端子金具２３の挿入方向に直交する方向に弾性変位するランスが不要になること、更に、雌型端子金具２３を抜け止め突起５１に係合させるためにアウターハウジング３３に装備した弾性押え片６１も前記インナーハウジング３７の挿入方向に沿って延出した単純な板状構造で良いことから、これらのインナーハウジング３７やアウターハウジング３３では、成形金型の型抜きが困難になることがない。従って、ランスによって雌型端子金具を抜け止めしていた従来のコネクタハウジングと比較すると、各ハウジングの成形金型の型抜きが容易になり、コネクタハウジングの成形金型の構造を単純化することもできる。 The inner housing 37 does not require a lance that is elastically displaced in a direction orthogonal to the insertion direction of the female terminal fitting 23, and further, the outer housing is used to engage the female terminal fitting 23 with the retaining protrusion 51. Since the elastic pressing piece 61 provided in 33 may have a simple plate-like structure extending along the insertion direction of the inner housing 37, in these inner housing 37 and outer housing 33, the molding die can be removed. It will not be difficult. Therefore, in comparison with the conventional connector housing in which the female terminal fitting is prevented from being removed by the lance, it becomes easy to remove the molding die of each housing, and the structure of the molding die of the connector housing can be simplified. it can.

なお、アウターハウジング３３に仮係止状態にあるインナーハウジング３７の端子収容部３５に雌型端子金具２３の挿入作業を行った場合に、雌型端子金具２３が正常に端子収容部３５内の抜け止め突起５１に係止される前に、雌型端子金具２３の挿入操作を終えると、雌型端子金具２３は前半部の上端が開口部５５に突出した不完全挿入状態で残留する。その状態のままインナーハウジング３７をアウターハウジング３３内に押し込むと、不完全挿入状態の雌型端子金具２３が弾性押え片６１との干渉によりインナーハウジング３７の後方に押し出されるため、視認により、不完全挿入状態の発生を容易に検知することができ、雌型端子金具２３の不完全挿入の防止に有効である。 When the female terminal fitting 23 is inserted into the terminal accommodating portion 35 of the inner housing 37 that is temporarily locked to the outer housing 33, the female terminal fitting 23 is normally removed from the terminal accommodating portion 35. When the insertion operation of the female terminal fitting 23 is finished before being locked to the stop protrusion 51, the female terminal fitting 23 remains in an incompletely inserted state in which the upper end of the front half projects into the opening 55. If the inner housing 37 is pushed into the outer housing 33 in this state, the female terminal fitting 23 in an incompletely inserted state is pushed out to the rear of the inner housing 37 due to interference with the elastic holding piece 61. The occurrence of the insertion state can be easily detected, and is effective in preventing incomplete insertion of the female terminal fitting 23.

また、上記一実施形態のコネクタ２１によれば、雌型端子金具２３が端子収容部３５の抜け止め突起５１により係止された正常嵌合状態で、インナーハウジング３７をアウターハウジング３３内に更に挿入して、インナーハウジング３７の略全体を前記アウターハウジング３３に挿入した状態にすると、インナーハウジング３７が本係止位置でアウターハウジング３３に結合された本係止状態になる。 Further, according to the connector 21 of the above-described embodiment, the inner housing 37 is further inserted into the outer housing 33 in the normal fitting state in which the female terminal fitting 23 is locked by the retaining protrusion 51 of the terminal accommodating portion 35. Then, when substantially the entire inner housing 37 is inserted into the outer housing 33, the inner housing 37 is in a final locking state where the inner housing 37 is coupled to the outer housing 33 at the final locking position.

この本係止状態では、アウターハウジング３３に装備された端子押え壁６３が、インナーハウジング３７の端子収容部３５の開口部５５を覆って、端子収容部３５に収容保持されている雌型端子金具２３の収容部下部壁３５ａからの浮き上がりを規制し、雌型端子金具２３が抜け止め突起５１により係止されている状態を維持する。 In this fully locked state, the terminal holding wall 63 provided in the outer housing 33 covers the opening 55 of the terminal accommodating portion 35 of the inner housing 37 and is accommodated and held in the terminal accommodating portion 35. 23, and the female terminal fitting 23 is kept locked by the retaining protrusion 51.

即ち、アウターハウジング３３の端子押え壁６３は、端子収容部３５の抜け止め突起５１が雌型端子金具２３に係合した状態を維持する二重係止手段として機能し、雌型端子金具２３に対する抜け止め性能を確実なものにする。 That is, the terminal pressing wall 63 of the outer housing 33 functions as a double locking means for maintaining the state in which the retaining projection 51 of the terminal housing portion 35 is engaged with the female terminal fitting 23, and Secure the retaining performance.

そして、二重係止手段として機能するアウターハウジング３３の端子押え壁６３は、インナーハウジング３７の挿入方向に沿って固定装備された剛体構造の隔壁でよいため、当該アウターハウジング３３の成形金型の型抜きを困難にすることもなく、アウターハウジング３３の成形金型の構造の単純化に適している。 Since the terminal pressing wall 63 of the outer housing 33 that functions as a double locking means may be a rigid partition wall that is fixedly installed along the insertion direction of the inner housing 37, the molding die of the outer housing 33 is provided. It is suitable for simplification of the structure of the molding die of the outer housing 33 without making it difficult to perform die cutting.

また、上記一実施形態のコネクタ２１では、端子収容部３５の底部の抜け止め突起５１だけでなく、収容部側部壁３５ｂの端子係止溝５７も、雌型端子金具２３の抜け方向の移動を規制する手段として機能するため、雌型端子金具２３の抜け止めをより強固にすることができる。 Further, in the connector 21 of the above-described embodiment, not only the retaining protrusion 51 on the bottom of the terminal accommodating portion 35 but also the terminal locking groove 57 on the accommodating portion side wall 35b is moved in the removing direction of the female terminal fitting 23. Therefore, the female terminal fitting 23 can be more securely prevented from coming off.

また、インナーハウジング３７側の端子係止溝５７は、上記実施形態に示したように端子収容部３５の収容部側部壁３５ｂの端部に切欠溝として形成することで、成形金型の型抜き性を低下させることもない。 Further, the terminal locking groove 57 on the inner housing 37 side is formed as a notch groove in the end portion of the housing portion side wall 35b of the terminal housing portion 35 as shown in the above embodiment, so that the mold of the molding die is formed. There is no reduction in punchability.

また、上記一実施形態のコネクタ２１では、傾斜案内部５３上を摺動する摺動突起２９の弾性力を適度な強さに設定しておくことで、弾性押え片６１が雌型端子金具２３の前半部を収容部下部壁３５ａ側に押し戻す際の抵抗力を加減することができ、雌型端子金具２３の装着時の操作性を向上させることができる。 Further, in the connector 21 according to the above-described embodiment, the elastic pressing piece 61 is set to the female terminal fitting 23 by setting the elastic force of the sliding projection 29 sliding on the inclined guide portion 53 to an appropriate strength. Thus, the resistance force when pushing the front half portion back toward the accommodating portion lower wall 35a can be adjusted, and the operability when the female terminal fitting 23 is attached can be improved.
