Description

本発明は、複数の雌端子と複数の雄端子とを接続するコネクタの嵌合構造に関する。   The present invention relates to a connector fitting structure for connecting a plurality of female terminals and a plurality of male terminals.

複数の雌端子がそれぞれ収容される複数の端子収容室が形成された雌端子用のハウジングと、複数の雌端子に接続される複数の雄端子を保持してなる雄端子用のハウジングを分離して形成したコネクタが知られている（例えば、特許文献１）。かかるコネクタにおいては、雌端子を端子収容室に挿入し、該端子収容室と接続させる段階（第１の接続）と、端子収容室に挿入した雌端子の接点部材に雄端子を摺接させる段階（第２の接続）に分けて、雌端子と雄端子を接続させている。そして、この場合、第１の接続を行うための第１の嵌合位置（仮嵌合状態）と、第２の接続を行うための第２の嵌合位置（本嵌合状態）で雄端子ハウジングと雌端子ハウジングをそれぞれ嵌合可能な構成としている。このようなコネクタ構成とすることで、雌端子と雄端子を接続するために負荷する荷重を、仮嵌合状態とするための荷重と本嵌合状態とするための荷重に分散することができ、かかる接続における最大荷重を低減することが可能となる。   A housing for a female terminal in which a plurality of terminal accommodating chambers each accommodating a plurality of female terminals is formed is separated from a housing for a male terminal that holds a plurality of male terminals connected to the plurality of female terminals. A connector formed in this manner is known (for example, Patent Document 1). In such a connector, the step of inserting the female terminal into the terminal accommodating chamber and connecting it to the terminal accommodating chamber (first connection), and the step of sliding the male terminal on the contact member of the female terminal inserted into the terminal accommodating chamber. The female terminal and the male terminal are connected separately in (second connection). In this case, the male terminal at the first fitting position (temporary fitting state) for performing the first connection and the second fitting position (main fitting state) for performing the second connection. The housing and the female terminal housing can be fitted with each other. By adopting such a connector configuration, the load applied to connect the female terminal and the male terminal can be dispersed into the load for making the temporary fitting state and the load for making the main fitting state. The maximum load in such connection can be reduced.

その一方で、雌端子ハウジングや雄端子ハウジングの製作公差によっては、これらの嵌合部にガタツキが生じることがあり、雌端子ハウジングや雄端子ハウジングを分離して形成した場合、両ハウジングの嵌合時の耐振（ガタツキ防止）を図る必要がある。そこで、特許文献１には、嵌合させるハウジングのフードの外側面と内側面に、ガタツキ防止リブとそのガタツキ防止リブが入り込むガタ付き防止溝を形成することにより、ガタ付き防止溝の溝壁面に直交する方向のガタツキを抑えたコネクタの構成が開示されている。しかしながら、かかるコネクタ構成では、溝壁面に平行な方向のガタツキを防止することについては考慮されていない。また、ガタツキ防止リブは、ガタ付き防止溝の溝壁面に直交する方向に変形しやすい形状となっている。このように、ハウジングの製作公差の程度によっては、耐振性能が十分に得られない場合も想定される。   On the other hand, depending on the manufacturing tolerances of the female terminal housing and male terminal housing, there may be rattling in these fitting parts. If the female terminal housing and male terminal housing are formed separately, the fitting of both housings will occur. It is necessary to improve the vibration resistance (prevention of rattling). Therefore, Patent Document 1 discloses that a ratchet prevention rib and a ratchet prevention groove into which the rattle prevention rib enters are formed on the outer side surface and the inner side surface of the hood of the housing to be fitted to the groove wall surface of the ratchet prevention groove. The structure of the connector which suppressed the backlash of the orthogonal direction is disclosed. However, in such a connector configuration, no consideration is given to preventing rattling in a direction parallel to the groove wall surface. The rattle prevention rib has a shape that is easily deformed in a direction perpendicular to the groove wall surface of the ratchet prevention groove. In this way, depending on the degree of manufacturing tolerance of the housing, it may be assumed that sufficient vibration resistance performance cannot be obtained.

本発明はこれを踏まえてなされたものであり、その解決しようとする課題は、雌端子と雄端子の接続時の最大荷重（負荷）を低減しつつ、端子ハウジングの嵌合時及び嵌合後におけるコネクタの耐振性の向上を図ることにある。   The present invention has been made based on this, and the problem to be solved is to reduce the maximum load (load) at the time of connection between the female terminal and the male terminal, while fitting the terminal housing and after the fitting. The purpose is to improve the vibration resistance of the connector.

上記課題を解決するため、本発明は、接点部を有する雌端子がそれぞれ挿入されて収容される複数の端子収容室が形成された雌端子ハウジングと、前記接点部と摺接して前記雌端子に接続される複数の雄端子を保持するとともに、前記雄端子を外部導体に接続するバスバがインサート成形された雄端子ハウジングを備え、前記雌端子ハウジングと前記雄端子ハウジングを嵌合させて前記雌端子と前記雄端子を電気的に接続させるコネクタであって、前記雌端子ハウジングと前記雄端子ハウジングは、第１の嵌合位置と第２の嵌合位置で互いに嵌合され、前記第１の嵌合位置は、前記雌端子が前記端子収容室に挿入されて前記接点部を前記雄端子へ臨ませた位置であって、前記雄端子が前記接点部と摺接する位置よりも手前に設定され、前記第２の嵌合位置は、前記雄端子が前記接点部に摺接する位置に設定されており、前記雄端子ハウジングには、前記雌端子ハウジングとの嵌合方向へ延出する樹脂製のアーム部と、前記バスバと連続されて前記嵌合方向へ延出する金属製のブラケット部が設けられ、前記雌端子ハウジングには、前記第１の嵌合位置で前記アーム部に形成された溝部と係合する第１の係合突起と、前記第２の嵌合位置で前記アーム部の溝部と係合する第２の係合突起と、前記第２の嵌合位置で前記ブラケット部に形成された孔部へ嵌入される嵌入突起と、前記ブラケット部を前記嵌入突起へガイドするガイド部が設けられていることを特徴とする。   In order to solve the above-described problems, the present invention provides a female terminal housing in which a plurality of terminal accommodating chambers in which female terminals each having a contact portion are inserted and accommodated, and a sliding contact with the contact portion to the female terminal. The female terminal housing includes a male terminal housing in which a bus bar for holding a plurality of connected male terminals and connecting the male terminals to an external conductor is insert-molded, and the female terminal housing and the male terminal housing are fitted to each other. And the male terminal housing, wherein the female terminal housing and the male terminal housing are fitted to each other at a first fitting position and a second fitting position, and the first fitting The joint position is a position where the female terminal is inserted into the terminal accommodating chamber and the contact portion faces the male terminal, and is set before the position where the male terminal is in sliding contact with the contact portion, Said The male terminal housing is set at a position where the male terminal slides on the contact portion, and the male terminal housing includes a resin arm portion extending in a fitting direction with the female terminal housing, and A metal bracket portion that is continuous with the bus bar and extends in the fitting direction is provided, and the female terminal housing engages with a groove portion formed in the arm portion at the first fitting position. A first engagement protrusion, a second engagement protrusion that engages with the groove of the arm portion at the second fitting position, and a hole formed in the bracket portion at the second fitting position. An insertion protrusion to be inserted into the insertion protrusion and a guide portion for guiding the bracket portion to the insertion protrusion are provided.

これによれば、雌端子と雄端子を接続させるために負荷する荷重を、雌端子ハウジングと雄端子ハウジングを第１の嵌合位置に位置付けるための荷重と第２の嵌合位置に移動させるための荷重に分散させることができ、かかる接続における最大荷重を低減することができる。この場合、雌端子ハウジングの第１の係合突起で雄端子ハウジングのアーム部を係止させることで、これらハウジングを第１の嵌合位置に位置付けることができる。また、雌端子ハウジングの第２の係合突起で雄端子ハウジングのアーム部を係止させるとともに、雌端子ハウジングの嵌入突起で雄端子ハウジングのブラケット部を係止させることで、これらハウジングを第２の嵌合位置に位置付けることができる。その際には、ガイド部でブラケット部を嵌入突起までガイドすることができ、雌端子ハウジングと雄端子ハウジングのガタツキを抑える（耐振性を向上させる）ことができる。そして、雌端子ハウジングと雄端子ハウジングを第２の嵌合位置に位置付けた後は、第２の係合突起のアーム部への係合及び嵌入突起のブラケット部への嵌入により、両ハウジングの耐振性を向上させることができ、これらハウジングを第２の嵌合位置に保持し続けることができる。   According to this, in order to move the load applied to connect the female terminal and the male terminal to the load and the second fitting position for positioning the female terminal housing and the male terminal housing at the first fitting position. The maximum load in such a connection can be reduced. In this case, by locking the arm portion of the male terminal housing with the first engaging protrusion of the female terminal housing, these housings can be positioned at the first fitting position. In addition, the arm portion of the male terminal housing is locked by the second engaging protrusion of the female terminal housing, and the bracket portion of the male terminal housing is locked by the fitting protrusion of the female terminal housing, so that these housings are Can be positioned at the fitting position. In this case, the bracket portion can be guided to the insertion protrusion by the guide portion, and rattling between the female terminal housing and the male terminal housing can be suppressed (vibration resistance can be improved). Then, after the female terminal housing and the male terminal housing are positioned at the second fitting position, the vibration-proofing of both housings is achieved by engaging the second engaging protrusion with the arm portion and inserting the fitting protrusion into the bracket portion. Performance can be improved, and these housings can be kept in the second fitting position.

この場合、前記ブラケット部には、円形の孔部を形成し、前記嵌入突起は、雌端子ハウジング上の断面円径を前記孔部の開口径と略同寸に設定して前記雌端子ハウジングから凸球面状に突出させればよい。   In this case, the bracket portion is formed with a circular hole portion, and the fitting projection is formed from the female terminal housing by setting the cross-sectional circle diameter on the female terminal housing to be approximately the same as the opening diameter of the hole portion. What is necessary is just to make it protrude in a convex spherical shape.

また、前記ガイド部は、前記嵌合方向に沿って並行をなして延設された一対の鉤型のリブを備え、前記リブの間で挟持した状態で前記ブラケット部をガイドする構成とすればよい。   Further, the guide portion includes a pair of hook-shaped ribs extending in parallel along the fitting direction, and is configured to guide the bracket portion while being sandwiched between the ribs. Good.

本発明によれば、雌端子と雄端子の接続時の最大荷重（負荷）を低減することができるとともに、端子ハウジングの嵌合時及び嵌合後におけるコネクタの耐振性の向上を図ることができる。   ADVANTAGE OF THE INVENTION According to this invention, while being able to reduce the maximum load (load) at the time of a female terminal and a male terminal connection, the improvement of the vibration resistance of the connector at the time of a terminal housing fitting and after fitting can be aimed at. .

以下、本発明のコネクタについて、添付図面を参照して説明する。図１は、本発明の一実施形態に係るコネクタの全体構成を、雄端子ハウジングと雌端子ハウジングを分離させた状態（嵌合前状態）で示す斜視図である。なお、以下の説明においては、図１に示す互いに直交する３つの軸方向をＸ方向、Ｙ方向及びＺ方向という。この場合、Ｚ方向が雌端子ハウジングと雄端子ハウジングの嵌合方向（組み付け方向）に相当し、Ｘ方向が該嵌合方向と直交する方向（例えば、水平方向）、Ｙ方向がこれら方向と直交する方向（例えば、垂直方向）にそれぞれ相当する。   Hereinafter, the connector of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an overall configuration of a connector according to an embodiment of the present invention in a state where a male terminal housing and a female terminal housing are separated (pre-fitting state). In the following description, three axial directions orthogonal to each other shown in FIG. 1 are referred to as an X direction, a Y direction, and a Z direction. In this case, the Z direction corresponds to the fitting direction (assembly direction) of the female terminal housing and the male terminal housing, the X direction is perpendicular to the fitting direction (for example, the horizontal direction), and the Y direction is perpendicular to these directions. This corresponds to the direction to be performed (for example, the vertical direction).

図１に示すように、コネクタ１は、接点部（図示しない）を有する雌端子３がそれぞれ挿入されて収容される複数の端子収容室４が形成された雌端子ハウジング５と、前記接点部と摺接して雌端子３に接続される複数の雄端子７を保持するとともに、雄端子７を外部導体（一例として、接地導体）に接続するバスバ６がインサート成形された雄端子ハウジング８を備えている。そして、コネクタ１は、雌端子ハウジング５と雄端子ハウジング８を嵌合させて雌端子３と雄端子７を電気的に接続させる。   As shown in FIG. 1, the connector 1 includes a female terminal housing 5 in which a plurality of terminal accommodating chambers 4 in which female terminals 3 having contact portions (not shown) are inserted and accommodated, and the contact portions. There is provided a male terminal housing 8 in which a bus bar 6 for holding a plurality of male terminals 7 slidably connected to the female terminals 3 and connecting the male terminals 7 to an external conductor (for example, a ground conductor) is insert-molded. Yes. The connector 1 electrically connects the female terminal 3 and the male terminal 7 by fitting the female terminal housing 5 and the male terminal housing 8 together.

雌端子３は、弾性変形可能な接点部を内包して筒状に形成された接点端子部３ｂと、電線２が圧着された圧着端子部３ｃと、電線２の端部外周に装着されたリング部材（一例として、リングパッキン）２ａを備えて形成されている。雌端子ハウジング５の端子収容室４は、雌端子３の接点端子部３ｂが収容される矩形筒状の収容室（以下、矩形筒部という。）と、雌端子３の圧着端子部３ｃ及び電線２のリングパッキン２ａが収容される円筒状の収容室（同、円筒部という。）４ｂを備えて形成されている。矩形筒部は、円筒部４ｂよりも雄端子ハウジング８側に位置付けられている。なお、雌端子ハウジング５の材質は弾性を有していれば特に限定されないが、本実施形態では雌端子ハウジング５が樹脂により構成されている場合を一例として想定する。   The female terminal 3 includes a contact terminal portion 3b formed into a cylindrical shape containing a resiliently deformable contact portion, a crimp terminal portion 3c to which the electric wire 2 is crimped, and a ring attached to the outer periphery of the end portion of the electric wire 2 A member (for example, a ring packing) 2a is provided. The terminal accommodating chamber 4 of the female terminal housing 5 includes a rectangular cylindrical accommodating chamber (hereinafter referred to as a rectangular cylindrical portion) in which the contact terminal portion 3b of the female terminal 3 is accommodated, a crimp terminal portion 3c of the female terminal 3, and an electric wire. A cylindrical storage chamber (hereinafter referred to as a cylindrical portion) 4b in which two ring packings 2a are stored. The rectangular tube portion is positioned closer to the male terminal housing 8 than the cylindrical portion 4b. In addition, although the material of the female terminal housing 5 will not be specifically limited if it has elasticity, in this embodiment, the case where the female terminal housing 5 is comprised with resin is assumed as an example.

この場合、雌端子３は、弾性変形可能な接点端子部３ｂの一側面に形成された係止穴（図示しない）を端子収容室４の内壁に弾性部材により形成されたランス（図示しない）と係合させることで、端子収容室４（端的には、雌端子ハウジング５）からの抜け止めを図った構成とすることができる。例えば、ランスは、端子収容室４の矩形筒部の所定側（一例として、Ｙ方向の下側）の内壁に形成する。この場合、ランスは、雌端子ハウジング５と同一の樹脂で、雌端子３の圧着端子部３ｃ及び電線２のリングパッキン２ａが収容される端子収容室４の円筒部４ｂから、雌端子３の接点端子部３ｂが収容される矩形筒部に伸延させて片持ち状に一体成形することができる。なお、ランスは、端子収容室４に１つずつ、雌端子３の数に応じてこれと同数だけ雌端子ハウジング５に対して形成すればよい。   In this case, the female terminal 3 has a locking hole (not shown) formed on one side surface of the elastically deformable contact terminal portion 3b and a lance (not shown) formed on the inner wall of the terminal accommodating chamber 4 by an elastic member. By engaging, it can be set as the structure which aimed at the removal from the terminal storage chamber 4 (in short, the female terminal housing 5). For example, the lance is formed on the inner wall on the predetermined side (for example, the lower side in the Y direction) of the rectangular cylindrical portion of the terminal accommodating chamber 4. In this case, the lance is made of the same resin as the female terminal housing 5, and contacts the female terminal 3 from the cylindrical portion 4 b of the terminal accommodating chamber 4 in which the crimp terminal portion 3 c of the female terminal 3 and the ring packing 2 a of the electric wire 2 are accommodated. It can be integrally formed in a cantilever shape by extending to a rectangular tube portion in which the terminal portion 3b is accommodated. In addition, what is necessary is just to form the lance with respect to the female terminal housing 5 according to the number of the female terminals 3 one by one in the terminal storage chamber 4 according to the number.

かかるランスは、端子収容室４に挿入された雌端子３の係止穴との係合前（以下、この状態を半挿入状態という。）、該雌端子３に押圧されて弾性撓み変形され、端子収容室４に挿入された雌端子３の係止穴との係合後（以下、この状態を本挿入状態という。）、弾性撓み復帰変形される。具体的には、半挿入状態において、ランスは端子収容室４の矩形筒部から退出するように（一例として、Ｙ方向の下側に）弾性撓み変形する。そして、本挿入状態において、ランスは雌端子３の係止穴の位置で端子収容室４の矩形筒部へ進出するように（一例として、Ｙ方向の上側に）弾性撓み復帰変形し、雌端子３の係止穴と係合する。これにより、本挿入状態においては、雌端子３がランスと係止され、雌端子３の端子収容室４からの抜け止めを図ることができる。   The lance is pressed by the female terminal 3 before being engaged with the locking hole of the female terminal 3 inserted in the terminal accommodating chamber 4 (hereinafter, this state is referred to as a half-inserted state), and is elastically deformed. After the engagement with the locking hole of the female terminal 3 inserted into the terminal accommodating chamber 4 (hereinafter, this state is referred to as the main insertion state), the elastic deformation is returned and deformed. Specifically, in the half-inserted state, the lance is elastically deformed so as to be retracted from the rectangular cylindrical portion of the terminal accommodating chamber 4 (as an example, on the lower side in the Y direction). In this insertion state, the lance is elastically deformed and deformed so as to advance into the rectangular tube portion of the terminal accommodating chamber 4 at the position of the locking hole of the female terminal 3 (as an example, on the upper side in the Y direction), and the female terminal 3 is engaged with the locking hole. Thereby, in this insertion state, the female terminal 3 is latched with the lance, and the removal from the terminal accommodating chamber 4 of the female terminal 3 can be aimed at.

雄端子ハウジング８には、バスバ６がインサート成形されており、本実施形態においては、雄端子７がバスバ６に突設され、雌端子３へ挿入接続される構成となっている。図２は、バスバ６の構成を示す斜視図である。図２に示すように、雄端子７は、バスバ６と一体的に形成されている。この場合、雄端子７は、バスバ６と同一の導電材からなり、その先端が雌端子ハウジング５の端子収容室４の矩形筒部に進入し、雌端子３の接点部と摺動接続可能に形成されている。例えば、バスバ６は、金属製の導体平板を打ち抜き加工や折り曲げ加工等することによって構成することができ、雄端子７は、かかるバスバ６の加工時にバスバ本体部６ａと同時に形成することができる。そして、かかるバスバ６に対して後述する樹脂製のアーム部８０、連結部８３及び被覆部８４（図１）を一体的にインサート成形することで、バスバ６、アーム部８０、連結部８３及び被覆部８４が一体化された雄端子ハウジング８を構成することができる。   The bus bar 6 is insert-molded in the male terminal housing 8. In the present embodiment, the male terminal 7 protrudes from the bus bar 6 and is inserted and connected to the female terminal 3. FIG. 2 is a perspective view showing the configuration of the bus bar 6. As shown in FIG. 2, the male terminal 7 is formed integrally with the bus bar 6. In this case, the male terminal 7 is made of the same conductive material as that of the bus bar 6, and the tip of the male terminal 7 enters the rectangular tube portion of the terminal accommodating chamber 4 of the female terminal housing 5 so that it can be slidably connected to the contact portion of the female terminal 3. Is formed. For example, the bus bar 6 can be formed by punching or bending a metal conductor flat plate, and the male terminal 7 can be formed simultaneously with the bus bar main body 6 a when the bus bar 6 is processed. The bus bar 6, the arm portion 80, the connecting portion 83, and the cover are integrally formed by integrally molding the resin-made arm portion 80, the connecting portion 83, and the covering portion 84 (FIG. 1), which will be described later. The male terminal housing 8 with which the part 84 was integrated can be comprised.

図２に示す構成において、雄端子７は、Ｘ方向に沿った板状のバスバ本体部６ａのＹ方向両端部から突出し、雌端子３との接続方向（図１において、矢印Ａ１１で示す方向）へ向けて板状に延出している。また、バスバ本体部６ａには、雄端子７を外部導体（一例として、接地導体）に接続するための接続部６ｂ,６ｃ及び後述するブラケット部８１が連続して設けられている。この場合、バスバ本体部６ａは、被覆部８４によって被覆されてアーム部８０及び連結部８３と一体化されており、雄端子７、接続部６ｂ,６ｃ及びブラケット部８１は、かかる被覆部８４から突出して外部へ露出されている（図１参照）。なお、図２には、バスバ本体部６ａのＹ方向各端部からそれぞれ４つずつ、合計８つの雄端子７を略等間隔で配した構成を一例として示すが、雄端子７は、端子収容室４に挿入される雌端子３の数に応じてこれと同数だけバスバ６に対して形成すればよく、その数は任意に設定することが可能である。また、雌端子ハウジング５と雄端子ハウジング８の間にリング状の密封部材（例えば、防水パッキン等）を装着することで、雌端子３と雄端子７との接続部分への浸水を防止することができ、コネクタ１を防水構造とすることが可能となる。   In the configuration shown in FIG. 2, the male terminal 7 protrudes from both ends in the Y direction of the plate-like bus bar main body 6a along the X direction and is connected to the female terminal 3 (the direction indicated by the arrow A11 in FIG. 1). It extends in the shape of a plate toward The bus bar body 6a is provided with connecting portions 6b and 6c for connecting the male terminal 7 to an external conductor (as an example, a ground conductor) and a bracket portion 81 described later. In this case, the bus bar main body portion 6a is covered with the covering portion 84 and integrated with the arm portion 80 and the connecting portion 83, and the male terminal 7, the connecting portions 6b and 6c, and the bracket portion 81 are separated from the covering portion 84. It protrudes and is exposed to the outside (see FIG. 1). FIG. 2 shows, as an example, a configuration in which a total of eight male terminals 7 are arranged at substantially equal intervals, four from each end in the Y direction of the bus bar main body 6a. According to the number of female terminals 3 inserted into the chamber 4, it is sufficient to form the same number of bus terminals 6 with respect to the bus bar 6, and the number can be arbitrarily set. In addition, by attaching a ring-shaped sealing member (for example, waterproof packing) between the female terminal housing 5 and the male terminal housing 8, it is possible to prevent water from entering the connecting portion between the female terminal 3 and the male terminal 7. Thus, the connector 1 can have a waterproof structure.

上述したように、コネクタ１は、雌端子ハウジング５と雄端子ハウジング８を嵌合させることで、雌端子３の接点部に雄端子７を摺接させて接続するように構成されている。この場合、雌端子ハウジング５と雄端子ハウジング８は、第１の嵌合位置と第２の嵌合位置、すなわち、２段階で嵌合される構成となっている。第１の嵌合位置は、雌端子３が端子収容室４に挿入されて接点部を雄端子７へ臨ませた位置であって、雄端子７が雌端子３の接点部と摺接する位置よりも手前に設定されている。また、第２の嵌合位置は、雄端子７が雌端子３の接点部に摺接する位置に設定されている。以下の説明においては、雌端子ハウジング５と雄端子ハウジング８が第１の嵌合位置にある状態を第１の嵌合状態、第２の嵌合位置にある状態を第２の嵌合状態という。なお、第１の嵌合状態及び第２の嵌合状態においては、上述した雌端子３の係止穴とランスとが係合された状態となっており、いずれも本挿入状態に相当する。このように、コネクタ１は、雌端子ハウジング５及び雄端子ハウジング８を第１の嵌合状態から第２の嵌合状態へ移行させる（第１の嵌合位置から第２の嵌合位置へ移動させる）ことで、雄端子７が雌端子３の接点部と摺接する構成となっている。これにより、雌端子３と雄端子７を接続させるために負荷する荷重を、第１の嵌合状態とするための荷重と第２の嵌合状態とするための荷重に分散させることができ、かかる接続における最大荷重を低減することができる。   As described above, the connector 1 is configured such that the male terminal 7 is slidably connected to the contact portion of the female terminal 3 by fitting the female terminal housing 5 and the male terminal housing 8 together. In this case, the female terminal housing 5 and the male terminal housing 8 are configured to be fitted in a first fitting position and a second fitting position, that is, in two stages. The first fitting position is a position where the female terminal 3 is inserted into the terminal accommodating chamber 4 and the contact portion faces the male terminal 7, and the male terminal 7 is in sliding contact with the contact portion of the female terminal 3. Is also set in the foreground. The second fitting position is set to a position where the male terminal 7 is in sliding contact with the contact portion of the female terminal 3. In the following description, a state in which the female terminal housing 5 and the male terminal housing 8 are in the first fitting position is referred to as a first fitting state, and a state in which the female terminal housing 8 is in the second fitting position is referred to as a second fitting state. . In addition, in the 1st fitting state and the 2nd fitting state, it is in the state which the latching hole and lance of the female terminal 3 mentioned above were engaged, and all correspond to this insertion state. Thus, the connector 1 shifts the female terminal housing 5 and the male terminal housing 8 from the first fitting state to the second fitting state (moves from the first fitting position to the second fitting position). By doing so, the male terminal 7 is in sliding contact with the contact portion of the female terminal 3. Thereby, the load applied to connect the female terminal 3 and the male terminal 7 can be dispersed into the load for making the first fitting state and the load for making the second fitting state, The maximum load in such connection can be reduced.

本実施形態において、雄端子ハウジング８には、雌端子ハウジング５との嵌合方向（図１において、矢印Ａ１１で示す方向）へ延出する樹脂製のアーム部８０と、バスバ６と連続されて嵌合方向へ延出する金属製のブラケット部８１が設けられている。   In this embodiment, the male terminal housing 8 is connected to the resin arm portion 80 extending in the fitting direction with the female terminal housing 5 (the direction indicated by the arrow A11 in FIG. 1) and the bus bar 6. A metal bracket portion 81 extending in the fitting direction is provided.

アーム部８０は、雄端子ハウジング８のＸ方向両側部から雌端子ハウジング５の外周面、具体的には、矩形筒部の外筺部４ｃのＸ方向に対する外側面４ｄへ向けて板状に延出されており、雌端子ハウジング５と雄端子ハウジング８との嵌合方向（Ｚ方向）に沿って形成された溝部（以下、係止溝という。）８２を有している。本実施形態においては、雄端子ハウジング８のＸ方向両側部からそれぞれ２つずつ、合計４つのアーム部８０が外筺部４ｃの外側面４ｄへ向けて延出された構成となっている。すなわち、雄端子ハウジング８のＸ方向各側部で２つ一組をなすアーム部８０（図１に示す８０ａ,８０ｂ、及び８０ｃ,８０ｄ）がＸ方向両端部で一対をなすように設けられた構成となっている。これにより、アーム部８０は、Ｘ方向の両側から雌端子ハウジング５の外筺部４ｃを挟み込むように、雌端子ハウジング５との嵌合方向（図１において、矢印Ａ１１で示す方向）に延出された構成をなす。また、雄端子ハウジング８のＸ方向各側部では、一組のアーム部８０が雄端子ハウジング８のＹ方向両端にそれぞれ１つずつ配されている。そして、これらのアーム部８０は、２つの連結部８３を介して連結されている。すなわち、雄端子ハウジング８の各側部においてＹ方向の一端側に配された２つのアーム部８０（一例として、８０ａ,８０ｃ）は、一方の連結部８３を介して互いに連続されている。同様に、Ｙ方向の他端側に配された２つのアーム部８０（一例として、８０ｂ,８０ｄ）は、他方の連結部８３を介して互いに連続されている。２つの連結部８３は、２つのアーム部８０の間（８０ａと８０ｃの間、及び８０ｂと８０ｄの間）へそれぞれ渡されるようにＸ方向に沿って延出されており、両端のアーム部８０（８０ａと８０ｃ、及び８０ｂと８０ｄ）と一体をなした構成となっている。   The arm portion 80 extends in a plate shape from both sides in the X direction of the male terminal housing 8 toward the outer peripheral surface of the female terminal housing 5, specifically, the outer surface 4d of the outer flange portion 4c of the rectangular cylindrical portion with respect to the X direction. It has a groove portion (hereinafter referred to as a locking groove) 82 formed along the fitting direction (Z direction) between the female terminal housing 5 and the male terminal housing 8. In the present embodiment, a total of four arm portions 80 are extended toward the outer side surface 4d of the outer flange portion 4c, two each from both sides in the X direction of the male terminal housing 8. That is, two arm portions 80 (80a, 80b, and 80c, 80d shown in FIG. 1) form a pair at each side portion in the X direction of the male terminal housing 8 so as to form a pair at both ends in the X direction. It has a configuration. Thus, the arm portion 80 extends in the fitting direction with the female terminal housing 5 (the direction indicated by arrow A11 in FIG. 1) so as to sandwich the outer flange portion 4c of the female terminal housing 5 from both sides in the X direction. The configuration is made. Further, one set of arm portions 80 is arranged at each end in the Y direction of the male terminal housing 8 at each side portion in the X direction of the male terminal housing 8. These arm portions 80 are connected through two connecting portions 83. That is, the two arm portions 80 (for example, 80 a and 80 c) arranged on one end side in the Y direction on each side portion of the male terminal housing 8 are connected to each other via one connecting portion 83. Similarly, two arm portions 80 (for example, 80b and 80d) arranged on the other end side in the Y direction are connected to each other via the other connecting portion 83. The two connecting portions 83 extend along the X direction so as to be passed between the two arm portions 80 (between 80a and 80c and between 80b and 80d). (80a and 80c, and 80b and 80d).

ブラケット部８１は、バスバ６のＸ方向一側部から雌端子ハウジング５の外周面、具体的には、バスバ本体部６ａから矩形筒部の外筺部４ｃのＸ方向に対する外側面４ｄへ向けて板状に延出されている。すなわち、ブラケット部８１は、バスバ６と一体的に連続された構成をなしている。これにより、後述するようにブラケット８１が雌端子ハウジング５の嵌入突起５２によって係止された際、バスバ６を雌端子ハウジング５に対して同時に位置決め固定することができる。この結果、例えば、バスバ６に設けられた雄端子７を雌端子３へ挿入接続させた場合に端子間の微摺動を抑止することができ、雄端子７や雌端子３の微摺動摩耗を抑制することが可能となる。   The bracket portion 81 is directed from one side portion in the X direction of the bus bar 6 to the outer peripheral surface of the female terminal housing 5, specifically from the bus bar main body portion 6a toward the outer surface 4d in the X direction of the outer flange portion 4c of the rectangular cylindrical portion. It is extended in the shape of a plate. That is, the bracket portion 81 is configured to be continuous with the bus bar 6 integrally. Thereby, when the bracket 81 is locked by the fitting protrusion 52 of the female terminal housing 5 as described later, the bus bar 6 can be simultaneously positioned and fixed with respect to the female terminal housing 5. As a result, for example, when the male terminal 7 provided on the bus bar 6 is inserted and connected to the female terminal 3, the fine sliding between the terminals can be suppressed, and the fine sliding wear of the male terminal 7 and the female terminal 3 can be suppressed. Can be suppressed.

本実施形態においては、バスバ６のＸ方向一側部から１つのブラケット部８１が外筺部４ｃの外側面４ｄへ向けて延出された構成となっている。この場合、ブラケット部８１は、雄端子ハウジング８のＸ方向一側部においてＹ方向両端に設けられた一組のアーム部８０（図１に示す８０ａ,８０ｂ）の間に位置付けられるように、バスバ６のＸ方向一側部に配されている。なお、ブラケット部８１は、雌端子ハウジング５と雄端子ハウジング８の嵌合を開始し、第１の嵌合状態から第２の嵌合状態へ移行させる（第１の嵌合位置から第２の嵌合位置へ移動させる）際、後述する雌端子ハウジング５の嵌入突起５２に突き当たって乗り上がり易いように、その突き当て部位（図３(ｃ)及び図４(ｃ)に示す延出先端８１ｂ）が嵌合方向（図１において、矢印Ａ１１で示す方向）へ先細り状となるように外側へ傾斜して形成されている。この場合、ブラケット部８１の延出先端８１ｂは、嵌入突起５２の傾斜に沿うように傾斜している。また、ブラケット部８１は、延出先端８１ｂがアーム部８０よりも嵌合方向（図１において、矢印Ａ１１で示す方向）へ突出して位置付けられるように、延出寸法が設定されている。そして、ブラケット部８１には、その延出先端８１ｂの近傍にＸ方向へ貫通する孔部８１ａが形成されている。図２には、孔部８１ａを円孔とした構成を一例として示す。なお、孔部８１ａは、第２の嵌合位置で後述する雌端子ハウジング５の嵌入突起５２を嵌入させるための孔であり、その構成（大きさや形状等）は嵌入突起５２の構成に応じて設定すればよい。   In the present embodiment, one bracket portion 81 extends from one side portion in the X direction of the bus bar 6 toward the outer side surface 4d of the outer flange portion 4c. In this case, the bracket portion 81 is positioned between a pair of arm portions 80 (80a and 80b shown in FIG. 1) provided at both ends in the Y direction on one side portion in the X direction of the male terminal housing 8. 6 on one side in the X direction. In addition, the bracket part 81 starts the fitting of the female terminal housing 5 and the male terminal housing 8, and shifts from the first fitting state to the second fitting state (from the first fitting position to the second fitting state). When it is moved to the fitting position), the abutting portion (the extended tip 81b shown in FIGS. 3C and 4C) is placed so as to easily hit the fitting protrusion 52 of the female terminal housing 5 described later. ) Is formed to incline outward so as to be tapered in the fitting direction (the direction indicated by arrow A11 in FIG. 1). In this case, the extending tip 81 b of the bracket portion 81 is inclined so as to follow the inclination of the fitting protrusion 52. Further, the extension dimension of the bracket part 81 is set so that the extension tip 81b is positioned to protrude from the arm part 80 in the fitting direction (the direction indicated by the arrow A11 in FIG. 1). The bracket portion 81 is formed with a hole portion 81a penetrating in the X direction in the vicinity of the extending tip 81b. FIG. 2 shows an example of a configuration in which the hole 81a is a circular hole. The hole 81 a is a hole for fitting a fitting protrusion 52 of the female terminal housing 5 described later at the second fitting position, and its configuration (size, shape, etc.) depends on the structure of the fitting protrusion 52. You only have to set it.

これに対し、雌端子ハウジング５には、第１の嵌合位置でアーム部８０に形成された係止溝８２と係合する第１の係合突起５０と、第２の嵌合位置でアーム部８０の係止溝８２と係合する第２の係合突起５１と、第２の嵌合位置でブラケット部８１に形成された孔部８１ａへ嵌入される嵌入突起５２と、ブラケット部８０を嵌入突起５２へガイドするガイド部５３が設けられている。   On the other hand, the female terminal housing 5 includes a first engagement protrusion 50 that engages with a locking groove 82 formed in the arm portion 80 at the first fitting position, and an arm at the second fitting position.

In the present embodiment, a total of four first engaging protrusions 50 project from the outer side surfaces 4d on both sides in the X direction of the outer flange portion 4c, two in total, in a substantially rectangular shape. That is, the first engaging projections 50 (for example, 50a and 50b shown in FIG. 1) that form a pair at each side portion in the X direction of the female terminal housing 5 are provided so as to form a pair at both side portions in the X direction. It is the composition which was made. Further, at each side portion of the female terminal housing 5 in the X direction, a pair of first engaging protrusions 50 are arranged one by one at both ends of the outer flange portion 4c in the Y direction. The first engaging protrusion 50 is abutted against the first engaging protrusion 50 so that the arm portion 80 can easily come into contact with the female terminal housing 5 and the male terminal housing 8 when the fitting is started. The part is formed to be inclined toward the outer surface 4d so as to be tapered in the fitting direction (the direction indicated by arrow A12 in FIG. 1).

第２の係合突起５１は、アーム部８０の係止溝８２に対応させて外筺部４ｃの外側面４ｄから突出するように設けられている。本実施形態においては、外筺部４ｃのＸ方向両側の外側面４ｄからそれぞれ２つずつ、合計４つの第２の係合突起５１が略矩形状に突出された構成となっている。すなわち、雌端子ハウジング５のＸ方向各側部で２つ一組をなす第２の係合突起５１（一例として、図１に示す５１ａ,５１ｂ）がＸ方向両側部で一対をなすように設けられた構成となっている。また、雌端子ハウジング５のＸ方向各側部では、一組の第２の係合突起５１が外筺部４ｃのＹ方向両端にそれぞれ１つずつ配されている。また、第２の係合突起５１は、雌端子ハウジング５と雄端子ハウジング８の嵌合を開始し、第１の嵌合状態から第２の嵌合状態へ移行させる（第１の嵌合位置から第２の嵌合位置へ移動させる）際、アーム部８０が突き当たって乗り上がり易いように、第２の係合突起５１の突き当て部位が嵌合方向（図１において、矢印Ａ１２で示す方向）へ先細り状となるように外側面４ｄへ向けて傾斜して形成されている。   The second engagement protrusion 51 is provided so as to protrude from the outer side surface 4d of the outer flange portion 4c so as to correspond to the locking groove 82 of the arm portion 80. In the present embodiment, a total of four second engaging protrusions 51 project from the outer side surfaces 4d on both sides in the X direction of the outer flange portion 4c, two in total, in a substantially rectangular shape. That is, the second engaging projections 51 (for example, 51a and 51b shown in FIG. 1) that form a pair at each side in the X direction of the female terminal housing 5 are provided so as to form a pair at both sides in the X direction. It is the composition which was made. Further, at each side portion of the female terminal housing 5 in the X direction, a pair of second engaging protrusions 51 are arranged one by one at both ends of the outer flange portion 4c in the Y direction. Further, the second engagement protrusion 51 starts the fitting of the female terminal housing 5 and the male terminal housing 8 and shifts from the first fitting state to the second fitting state (first fitting position). 1), the abutting portion of the second engaging protrusion 51 is in the fitting direction (the direction indicated by the arrow A12 in FIG. 1) so that the arm portion 80 can easily hit and ride up. ) To be inclined toward the outer surface 4d.

第１の係合突起５０及び第２の係合突起５１は、略同一の大きさ及び形状をなして構成され、いずれも外側面４ｄのＸ方向に対して雄端子ハウジング８側に位置付けられている。具体的には、雄端子ハウジング８との嵌合方向（図１において、矢印Ａ１２で示す方向）に対して第１の係合突起５０が手前側（第１の嵌合位置に相当）、第２の係合突起５１が奥側（第２の嵌合位置に相当）となるように位置付けられている。すなわち、第１の係合突起５０と第２の係合突起５１の配設間隔は、雌端子ハウジング５と雄端子ハウジング８を第１の嵌合位置から第２の嵌合位置へ移動させる際の移動距離に相当する。換言すれば、第１の係合突起５０と第２の係合突起５１は、雌端子ハウジング５と雄端子ハウジング８を第１の嵌合位置から第２の嵌合位置へ移動させる際の嵌合方向（Ｚ方向）に対する相対移動距離に相当する間隔を外側面４ｄのＺ方向に沿って空けて、外筺部４ｃのＹ方向両端にそれぞれ配すればよい。   The first engagement protrusion 50 and the second engagement protrusion 51 are configured to have substantially the same size and shape, and both are positioned on the male terminal housing 8 side with respect to the X direction of the outer surface 4d. Yes. Specifically, the first engaging protrusion 50 is on the near side (corresponding to the first fitting position) with respect to the fitting direction with the male terminal housing 8 (the direction indicated by arrow A12 in FIG. 1), the first The two engaging protrusions 51 are positioned so as to be on the back side (corresponding to the second fitting position). That is, the arrangement interval between the first engagement protrusion 50 and the second engagement protrusion 51 is determined when the female terminal housing 5 and the male terminal housing 8 are moved from the first fitting position to the second fitting position. It corresponds to the movement distance. In other words, the first engaging protrusion 50 and the second engaging protrusion 51 are fitted when the female terminal housing 5 and the male terminal housing 8 are moved from the first fitting position to the second fitting position. What is necessary is just to distribute | arrange the space | interval equivalent to the relative movement distance with respect to a matching direction (Z direction) along the Z direction of the outer surface 4d, respectively, at the Y direction both ends of the outer collar part 4c.

嵌入突起５２は、ブラケット部８１の孔部８１ａに対応させて外筺部４ｃの外側面４ｄから突出するように設けられている。本実施形態においては、外筺部４ｃのＸ方向片側の外側面４ｄから嵌入突起５２が凸曲状（一例として、凸球面状）に突出された構成となっている。この場合、嵌入突起５２は、外筺部４ｃのＸ方向片側においてＹ方向両端に設けられた一組の第１の係合突起５０（図１に示す５０ａ,５０ｂ）及び第２の係合突起５１（同図に示す５１ａ,５１ｂ）の略中間部位で、Ｘ方向に対して第１の係合突起５０及び第２の係合突起５１とは反対側の端部に位置付けられるように、Ｘ方向片側の外側面４ｄに配されている。また、嵌入突起５２は、外筺部４ｃのＸ方向片側に設けられた後述するガイド部５３のリブ５３ａ,５３ｂに対し、Ｙ方向及びＺ方向の双方の略中間部位に位置付けられるように、Ｘ方向片側の外側面４ｄに配されている。   The fitting protrusion 52 is provided so as to protrude from the outer side surface 4d of the outer flange portion 4c in correspondence with the hole portion 81a of the bracket portion 81. In the present embodiment, the insertion protrusion 52 protrudes from the outer side surface 4d on one side in the X direction of the outer flange portion 4c into a convex curve (for example, a convex spherical shape). In this case, the fitting protrusions 52 are a set of first engaging protrusions 50 (50a and 50b shown in FIG. 1) and second engaging protrusions provided at both ends in the Y direction on one side in the X direction of the outer flange portion 4c. 51 (51a, 51b shown in the figure) at an approximately intermediate position so as to be positioned at the end opposite to the first engaging protrusion 50 and the second engaging protrusion 51 with respect to the X direction. It is arranged on the outer side surface 4d on one side in the direction. Further, the insertion protrusion 52 is positioned so as to be positioned at a substantially intermediate portion in both the Y direction and the Z direction with respect to ribs 53a and 53b of the guide portion 53 described later provided on one side in the X direction of the outer flange portion 4c. It is arranged on the outer side surface 4d on one side in the direction.

なお、嵌入突起５２は、第２の嵌合位置でブラケット部８１の孔部８１ａへ嵌入される突起であり、その構成（大きさや形状等）は孔部８１ａの構成に応じて設定すればよい。一例として、本実施形態において、嵌入突起５２は、雌端子ハウジング５上、具体的には外側面４ｄ上の断面円径を孔部８１ａの開口径と略同寸に設定して雌端子ハウジング５の外側面４ｄから凸曲状（凸球面状）に突出させている。これにより、雌端子ハウジング５と雄端子ハウジング８を第１の嵌合位置から第２の嵌合位置へ移動させた際、嵌入突起５２を孔部８１ａの開口縁と密着した状態で孔部８１ａへ嵌入させることができる。そして、嵌入後は、外側面４ｄ上の全方向に対するガタツキを抑制すること、つまり耐振性の向上を図ることができ、かかる嵌入状態を保持することが可能となる。すなわち、コネクタ１に対し、これら嵌入突起５２と孔部８１ａでスライドロック（スルーロック）構造を持たせることができる。また、ブラケット部８１は、金属製であるため樹脂製等とするよりも剛性が高く、孔部８１ａへの嵌入突起５２の嵌入後において、外側面４ｄ上の全方向（例えば、Ｙ方向及びＺ方向）に加えて、外側面４ｄに垂直な方向（Ｘ方向）に対してもガタツキ抑制（耐振性向上）効果を高めることができる。   The insertion protrusion 52 is a protrusion that is inserted into the hole 81a of the bracket portion 81 at the second fitting position, and the configuration (size, shape, etc.) may be set according to the configuration of the hole 81a. . As an example, in the present embodiment, the insertion protrusion 52 is formed on the female terminal housing 5 by setting the cross-sectional circle diameter on the female terminal housing 5, specifically, the outer diameter of the outer surface 4 d to be approximately the same as the opening diameter of the hole 81 a. It protrudes from the outer side surface 4d into a convex curved shape (convex spherical shape). Accordingly, when the female terminal housing 5 and the male terminal housing 8 are moved from the first fitting position to the second fitting position, the hole 81a is in a state where the fitting protrusion 52 is in close contact with the opening edge of the hole 81a. Can be inserted. Then, after the insertion, it is possible to suppress rattling in all directions on the outer surface 4d, that is, to improve the vibration resistance, and to maintain such an insertion state. That is, the connector 1 can be provided with a slide lock (through lock) structure by the fitting protrusion 52 and the hole 81a. In addition, since the bracket portion 81 is made of metal, it has higher rigidity than that made of resin or the like. After the insertion protrusion 52 is inserted into the hole portion 81a, the bracket portion 81 is omnidirectional (for example, the Y direction and the Z direction) on the outer surface 4d. In addition to (direction), the backlash suppression (vibration resistance improvement) effect can be enhanced also in the direction (X direction) perpendicular to the outer surface 4d.

ガイド部５３は、雌端子ハウジング５と雄端子ハウジング８の嵌合方向（Ｚ方向）に沿って並行をなして延設された一対の鉤型のリブ５３ａ,５３ｂを備え、これらリブ５３ａ,５３ｂの間で挟持した状態でブラケット部８１をガイドする。換言すれば、ガイド部５３は、外筺部４ｃの外側面４ｄに所定間隔を空けて対向配置された鉤型のリブ５３ａ,５３ｂと、これらリブ５３ａ,５３ｂの間に形成される空間（以下、ガイド溝という。）５３ｃで構成されている。本実施形態において、リブ５３ａ,５３ｂは、外筺部４ｃのＸ方向片側の外側面４ｄ、つまり嵌入突起５２が設けられた外側面４ｄに設けられている。この場合、リブ５３ａ,５３ｂは、ブラケット部８１のＹ方向に対する幅と略同寸の間隔を空けてかかる外側面４ｄから突出した後、該間隔を狭めるように互いにＹ方向に対して逆向きに屈曲した構成となっている。また、リブ５３ａ,５３ｂは、ブラケット部８１のＸ方向に対する肉厚と略同寸の高さで外側面４ｄから突出している。これにより、リブ５３ａ,５３ｂの間にブラケット部８１を収容可能な空間を形成することができ、かかる空間がガイド溝５３ｃとして構成されている。   The guide portion 53 includes a pair of bowl-shaped ribs 53a and 53b extending in parallel along the fitting direction (Z direction) of the female terminal housing 5 and the male terminal housing 8, and the ribs 53a and 53b. The bracket portion 81 is guided while being sandwiched between the two. In other words, the guide portion 53 is a space formed between the ribs 53a, 53b and the ribs 53a, 53b disposed opposite to the outer surface 4d of the outer flange portion 4c at a predetermined interval (hereinafter referred to as the ribs 53a, 53b). This is referred to as a guide groove.) 53c. In the present embodiment, the ribs 53a and 53b are provided on the outer side surface 4d on one side in the X direction of the outer flange portion 4c, that is, the outer side surface 4d provided with the fitting protrusions 52. In this case, after the ribs 53a and 53b protrude from the outer surface 4d with an interval substantially equal to the width of the bracket portion 81 in the Y direction, the ribs 53a and 53b are opposite to each other in the Y direction so as to reduce the interval. It has a bent configuration. The ribs 53a and 53b protrude from the outer surface 4d at a height approximately the same as the thickness of the bracket portion 81 in the X direction. Thereby, a space capable of accommodating the bracket portion 81 can be formed between the ribs 53a and 53b, and the space is configured as a guide groove 53c.

すなわち、ブラケット部８１をリブ５３ａ,５３ｂに沿って移動させることで、かかるブラケット部８１をガイド溝５３ｃへ進入させて雌端子ハウジング５の嵌入突起５２までガイドすることができる。その際、ブラケット部８１がリブ５３ａ,５３ｂの間で挟持された状態でガイド部５３によってガイドされるため、雌端子ハウジング５と雄端子ハウジング８を第１の嵌合位置から第２の嵌合位置へ移動させる際、これらハウジング５,８のＹ方向へのガタツキを抑制することができる。また、リブ５３ａ,５３ｂは、第１の嵌合状態においてブラケット部８１の延出端部８１ｂの近傍をガイド溝５３ｃへ収容可能で、第２の嵌合状態において延出端部８１ｂの近傍を含む、ブラケット部８の略半分程度の部分をガイド溝５３ｃへ収容可能となるように、Ｚ方向（雌端子ハウジング５と雄端子ハウジング８の嵌合方向）に対する寸法を設定すればよい。   That is, by moving the bracket portion 81 along the ribs 53 a and 53 b, the bracket portion 81 can be guided into the guide groove 53 c and guided to the fitting protrusion 52 of the female terminal housing 5. At this time, since the bracket portion 81 is guided by the guide portion 53 while being sandwiched between the ribs 53a and 53b, the female terminal housing 5 and the male terminal housing 8 are second fitted from the first fitting position. When moving to the position, the backlash in the Y direction of these housings 5 and 8 can be suppressed. The ribs 53a and 53b can accommodate the vicinity of the extended end portion 81b of the bracket portion 81 in the guide groove 53c in the first fitted state, and the vicinity of the extended end portion 81b in the second fitted state. The dimension with respect to the Z direction (the fitting direction of the female terminal housing 5 and the male terminal housing 8) may be set so that a substantially half portion of the bracket portion 8 can be accommodated in the guide groove 53c.

ここで、雌端子ハウジング５と雄端子ハウジング８を嵌合させて相互に組み付ける場合の手順の一例を示す。かかる組み付けは、雌端子３を端子収容室４へ挿入して本挿入状態（つまり、雄端子７と接続可能な状態）とするべく、雌端子ハウジング５に雄端子ハウジング８を嵌め合わせて第１の嵌合状態とする段階と、雄端子７を雌端子３の接点部に摺接させ、雄端子７と雌端子３を電気的に接続させる第２の嵌合状態とする段階の２段階で行う。図３には、雌端子ハウジング５と雄端子ハウジング８を第１の嵌合位置に位置付けた状態（第１の嵌合状態）を示しており、同図(ａ)は斜視図、同図(ｂ)は側面図、同図(ｃ)は同図(ｂ)の矢印Ａ３部分における横断面を矢印方向から示す図である。また、図４には、雌端子ハウジング５と雄端子ハウジング８を第２の嵌合位置に位置付けた状態（第２の嵌合状態）を示しており、同図(ａ)は斜視図、同図(ｂ)は側面図、同図(ｃ)は同図(ｂ)の矢印Ａ４部分における横断面を矢印方向から示す図である。なお、図３(ａ),(ｃ)及び図４(ａ),(ｃ)において、雌端子３は図示を省略している。   Here, an example of a procedure when the female terminal housing 5 and the male terminal housing 8 are fitted and assembled to each other will be shown. Such assembly is performed by fitting the male terminal housing 8 to the female terminal housing 5 so that the female terminal 3 is inserted into the terminal accommodating chamber 4 to be in the fully inserted state (that is, a state where it can be connected to the male terminal 7). And the second fitting state in which the male terminal 7 is brought into sliding contact with the contact portion of the female terminal 3 and the male terminal 7 and the female terminal 3 are electrically connected. Do. FIG. 3 shows a state in which the female terminal housing 5 and the male terminal housing 8 are positioned at the first fitting position (first fitting state). FIG. 3 (a) is a perspective view, FIG. FIG. 4B is a side view, and FIG. 5C is a diagram showing a cross section taken along the arrow A3 in FIG. FIG. 4 shows a state in which the female terminal housing 5 and the male terminal housing 8 are positioned at the second fitting position (second fitting state). FIG. 4 (a) is a perspective view. FIG. 2B is a side view, and FIG. 2C is a diagram showing a cross section taken along the arrow A4 in FIG. In FIGS. 3A and 3C and FIGS. 4A and 4C, the female terminal 3 is not shown.

第１の嵌合状態とするにあたって、第１の係合突起５０とアーム部８０を正対させるように雌端子ハウジング５と雄端子ハウジング８を位置付ける。そして、アーム部８０の延出先端を第１の係合突起５０と当接させる。この状態で所定の押込力（図１におけるＡ１１方向への力）を作用させると、アーム部８０は、かかる押込力に抗してＸ方向に対して外側へ広がるように弾性撓み変形し、第１の係合突起５０へ乗り上げる。そして、アーム部８０が第１の係合突起５０を完全に乗り越えると、該アーム部８０が内側へ狭まるように弾性撓み復帰変形する。この結果、第１の係合突起５０がアーム部８０の係止溝８２内に入り込んで係止溝８２と係合され、アーム部８０を係止する。換言すれば、雌端子ハウジング５と雄端子ハウジング８が第１の嵌合位置となる。そして、雌端子３を端子収容室４に挿入し、雌端子３の係合穴をランスに係止させて抜け止めする。これにより、雌端子ハウジング５及び雄端子ハウジング８は、第１の嵌合状態となる（図３に示す状態）。このように第１の嵌合状態となると、雌端子ハウジング５と雄端子ハウジング８との嵌合を解除するには、アーム部８０を反らせて係止溝８２と第１の係合突起５０との係止を解除することになるが、板状のアーム部８０を反らすだけの解除力で済む。   In the first fitting state, the female terminal housing 5 and the male terminal housing 8 are positioned so that the first engagement protrusion 50 and the arm portion 80 face each other. Then, the extended tip of the arm portion 80 is brought into contact with the first engagement protrusion 50. When a predetermined pushing force (force in the A11 direction in FIG. 1) is applied in this state, the arm portion 80 is elastically bent and deformed so as to spread outward in the X direction against the pushing force. It rides on the first engaging protrusion 50. When the arm portion 80 completely gets over the first engagement protrusion 50, the arm portion 80 is elastically bent and deformed so as to narrow inward. As a result, the first engaging protrusion 50 enters the locking groove 82 of the arm portion 80 and engages with the locking groove 82 to lock the arm portion 80. In other words, the female terminal housing 5 and the male terminal housing 8 are in the first fitting position. Then, the female terminal 3 is inserted into the terminal accommodating chamber 4, and the engagement hole of the female terminal 3 is locked to the lance to prevent the female terminal 3 from coming off. Thereby, the female terminal housing 5 and the male terminal housing 8 are in the first fitting state (the state shown in FIG. 3). In this way, in the first fitting state, in order to release the fitting between the female terminal housing 5 and the male terminal housing 8, the arm portion 80 is bent and the locking groove 82 and the first engaging protrusion 50 are However, a release force that only warps the plate-like arm portion 80 is sufficient.

また、アーム部８０の延出先端を第１の係合突起５０と当接させた状態で前記押込力を作用させると、ブラケット部８１がガイド部５３のリブ５３ａ,５３ｂに沿ってガイドされつつ、ガイド溝５３ｃへ進入する。そして、第１の係合突起５０がアーム部８０を係止し、雌端子ハウジング５と雄端子ハウジング８が第１の嵌合位置となると、ブラケット部８１は、延出先端８１ｂの近傍がガイド溝５３ｃへ収容された状態となる。換言すれば、第１の嵌合位置において、ブラケット部８１は、延出先端８１ｂが雌端子ハウジング５の嵌入突起５２にかかった状態となる（図３(ｃ)に示す状態）。   Further, when the pushing force is applied in a state where the extended tip of the arm portion 80 is in contact with the first engaging protrusion 50, the bracket portion 81 is being guided along the ribs 53 a and 53 b of the guide portion 53. Then, it enters the guide groove 53c. Then, when the first engaging protrusion 50 locks the arm portion 80 and the female terminal housing 5 and the male terminal housing 8 are in the first fitting position, the bracket portion 81 is guided in the vicinity of the extended tip 81b. It will be in the state accommodated in the groove | channel 53c. In other words, at the first fitting position, the bracket portion 81 is in a state where the extended tip 81b is engaged with the fitting protrusion 52 of the female terminal housing 5 (the state shown in FIG. 3C).

かかる第１の嵌合状態から第２の嵌合状態へ移行させるにあたっては、第１の嵌合状態となっている雄端子ハウジング８に対して前記押込力を作用させ、アーム部８０の延出先端を第２の係合突起５１と当接させる。この状態でかかる押込力をさらに作用させると、アーム部８０は、該押込力に抗してＸ方向に対して外側へ広がるように弾性撓み変形し、第２の係合突起５１へ乗り上げる。そして、アーム部８０が第２の係合突起５１を完全に乗り越えると、該アーム部８０が内側へ狭まるように弾性撓み復帰変形する。この結果、第２の係合突起５１がアーム部８０の係止溝８２内に入り込んで係止溝８２と係合され、アーム部８０を係止する。換言すれば、雌端子ハウジング５と雄端子ハウジング８が第２の嵌合位置となる。これにより、雌端子ハウジング５及び雄端子ハウジング８は、第２の嵌合状態となる（図４に示す状態）。かかる第２の嵌合位置においては、第１の係合突起５０もアーム部８０の係止溝８２と係合された状態に保たれている。そして、第２の嵌合状態においては、雄端子７を雌端子３の接点部に摺接させることができ、雄端子７と雌端子３を電気的に接続させることができる。なお、第２の嵌合状態となると、雌端子ハウジング５と雄端子ハウジング８との嵌合を解除するには、アーム部８０を反らせて係止溝８２と第２の係合突起５１との係止を解除することになるが、板状のアーム部８０を反らすだけの解除力で済む。   In shifting from the first fitting state to the second fitting state, the pushing force is applied to the male terminal housing 8 in the first fitting state, and the arm portion 80 is extended. The tip is brought into contact with the second engagement protrusion 51. When this pushing force is further applied in this state, the arm portion 80 is elastically deformed so as to spread outward in the X direction against the pushing force, and rides on the second engagement protrusion 51. When the arm portion 80 completely gets over the second engagement protrusion 51, the arm portion 80 is elastically bent and deformed so as to be narrowed inward. As a result, the second engaging projection 51 enters the locking groove 82 of the arm portion 80 and is engaged with the locking groove 82 to lock the arm portion 80. In other words, the female terminal housing 5 and the male terminal housing 8 are in the second fitting position. Thereby, the female terminal housing 5 and the male terminal housing 8 are in the second fitting state (the state shown in FIG. 4). In the second fitting position, the first engagement protrusion 50 is also kept engaged with the locking groove 82 of the arm portion 80. And in the 2nd fitting state, the male terminal 7 can be slidably contacted to the contact part of the female terminal 3, and the male terminal 7 and the female terminal 3 can be electrically connected. In the second fitting state, in order to release the fitting between the female terminal housing 5 and the male terminal housing 8, the arm portion 80 is bent and the locking groove 82 and the second engaging protrusion 51 are separated. The locking is released, but a release force that only warps the plate-like arm portion 80 is sufficient.

一方、第１の嵌合状態となっている雄端子ハウジング８に対して前記押込力を作用させると、ブラケット部８１がガイド部５３のリブ５３ａ,５３ｂに沿ってガイドされつつ、ガイド溝５３ｃへさらに進入し、嵌入突起５２と当接する。この状態でかかる押込力をさらに作用させると、ブラケット部８１は、該押込力に抗してＸ方向に対して外側へ広がるように弾性撓み変形し、嵌入突起５２へ乗り上げるとともに、リブ５３ａ,５３ｂと当接する。そして、ブラケット部８１は、嵌入突起５２及びリブ５３ａ,５３ｂに対して摺動し、孔部８１ａの全体が嵌入突起５２上に位置付けられるまでガイド溝５３ｃへ進入する。このように孔部８１ａの全体が嵌入突起５２上に位置付けられると、ブラケット部８１は、嵌入突起５２の突出面（凸曲面）に沿って内側へ狭まるように弾性撓み復帰変形し、孔部８１ａへ嵌入突起５２を嵌入させる。この結果、ブラケット部８１が嵌入突起５２によって係止され、雌端子ハウジング５と雄端子ハウジング８が第２の嵌合位置、すなわち第２の嵌合状態となる（図４に示す状態）。   On the other hand, when the pushing force is applied to the male terminal housing 8 that is in the first fitting state, the bracket portion 81 is guided along the ribs 53a and 53b of the guide portion 53, and into the guide groove 53c. It further enters and comes into contact with the fitting protrusion 52. When this pressing force is further applied in this state, the bracket portion 81 is elastically bent and deformed so as to spread outward in the X direction against the pressing force and rides on the fitting protrusion 52 and the ribs 53a and 53b. Abut. The bracket portion 81 slides relative to the insertion protrusion 52 and the ribs 53a and 53b, and enters the guide groove 53c until the entire hole portion 81a is positioned on the insertion protrusion 52. Thus, when the whole hole 81a is positioned on the insertion protrusion 52, the bracket part 81 is elastically bent and restored and deformed so as to narrow inward along the protruding surface (convex curved surface) of the insertion protrusion 52, and the hole 81a. The fitting projection 52 is inserted. As a result, the bracket portion 81 is locked by the fitting protrusion 52, and the female terminal housing 5 and the male terminal housing 8 are in the second fitting position, that is, the second fitting state (the state shown in FIG. 4).

なお、第２の係合突起５１が係止溝８２と係合され、アーム部８０を係止した状態、及び嵌入突起５２が孔部８１ａへ嵌入され、ブラケット部８１を係止した状態、つまり第２の嵌合状態は、雌端子３と雄端子７の電気的な接続状態と同期して生ずる。そして、第２の嵌合状態により、雌端子３と雄端子７の電気的な接続状態が維持される。また、雌端子３と雄端子７を電気的に切断させる場合には、上述した接続手順と逆の手順を順次行えばよい。   The second engaging projection 51 is engaged with the locking groove 82 and the arm portion 80 is locked, and the fitting projection 52 is fitted into the hole 81a and the bracket portion 81 is locked. The second fitting state occurs in synchronization with the electrical connection state between the female terminal 3 and the male terminal 7. And the electrical connection state of the female terminal 3 and the male terminal 7 is maintained by the 2nd fitting state. Further, when the female terminal 3 and the male terminal 7 are electrically disconnected, a procedure reverse to the connection procedure described above may be sequentially performed.

以上、本実施形態に係るコネクタ１によれば、雌端子３と雄端子７の接続時の最大荷重（負荷）を低減することができるとともに、雌端子ハウジング５と雄端子ハウジング８の嵌合時及び嵌合後におけるコネクタ１の耐振性の向上を図ることができる。   As described above, according to the connector 1 according to the present embodiment, the maximum load (load) when the female terminal 3 and the male terminal 7 are connected can be reduced, and the female terminal housing 5 and the male terminal housing 8 can be fitted together. In addition, the vibration resistance of the connector 1 after fitting can be improved.
