Description

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

従来、電線の端末部に接続された端子金具が収容されるハウジングに、電線の動きを抑制する電線保持部材が組み付けられているコネクタが知られている。例えば下記特許文献１に記載されたコネクタの電線保持部材は、並設された複数のキャビティを幅方向に横切る本体部と、本体部からハウジングへの組み付け方向に延出する一対の係止アームとを有している。電線保持部材は、ハウジングの上面側に組み付けられるものであり、ハウジングには、電線保持部材が組み付けられる連通空間が形成されている。連通空間の左右両面には、一対の係止アームに設けられた係止突起が係止可能な本係止用突起が突設されている。電線保持部材を連通空間内に差し込むと、一対の係止アームが連通空間の左右両側面に接触して内側に弾性撓みし、組み付け完了時には外側に弾性復帰して本係止突起に係止するようになっている。 2. Description of the Related Art Conventionally, there is known a connector in which a wire holding member that suppresses the movement of an electric wire is assembled in a housing that accommodates a terminal fitting connected to a terminal portion of the electric wire. For example, an electric wire holding member for a connector described in Patent Document 1 below includes a main body section that traverses a plurality of cavities arranged side by side in the width direction, and a pair of locking arms that extend in the assembly direction from the main body section to the housing. have. The electric wire holding member is assembled on the upper surface side of the housing, and a communication space in which the electric wire holding member is assembled is formed in the housing. On both the left and right sides of the communication space, main locking projections that can lock the locking projections provided on the pair of locking arms are provided. When the wire holding member is inserted into the communication space, the pair of locking arms come into contact with the left and right side surfaces of the communication space and elastically bend inward.

しかしながら、上記のような構成では、本係止突起がハウジングの内面に形成されているので、係止突起と本係止突起とが正規の係止状態に至っているかを確認し難いという問題がある。また、電線が引き上げられて電線保持部材の本体部に上向きの力が加わると、一対の係止アームが内側へ変位し、係止突起が本係止突起から外れてしまう虞を生じる。 However, in the configuration as described above, since the main locking projection is formed on the inner surface of the housing, there is a problem that it is difficult to confirm whether the locking projection and the main locking projection have reached a normal locking state. . Further, when the electric wire is pulled up and an upward force is applied to the main body portion of the electric wire holding member, the pair of locking arms are displaced inward, and there is a possibility that the locking projections are detached from the main locking projections.

本発明は上記のような事情に基づいて完成されたものであって、電線保持部材とハウジングとの係止状態を容易に確認することができ、またハウジングに対する電線保持部材の係止力を向上することが可能なコネクタを提供することを目的とする。 The present invention has been completed based on the above circumstances, and can easily check the locking state between the wire holding member and the housing, and improve the locking force of the wire holding member with respect to the housing. An object of the present invention is to provide a connector that can be used.

本発明のコネクタは、電線の端末部に接続された端子金具が収容されるキャビティを有するハウジングと、前記ハウジングの一面側に開口する組付部に組み付けられる電線保持部材と、を有し、前記電線保持部材が、前記キャビティを幅方向に横切る本体部と、前記本体部から前記ハウジングへの組み付け方向に延出する一対の係止アームと、を有し、前記一対の係止アームの内側には、前記ハウジングの外面のうち前記一面側とは反対の他面側に係止する係止部が突出して設けられているものである。 The connector of the present invention includes a housing having a cavity in which a terminal fitting connected to a terminal portion of an electric wire is accommodated, and an electric wire holding member to be assembled to an assembling portion opened on one surface side of the housing, The electric wire holding member has a main body section that crosses the cavity in the width direction, and a pair of locking arms that extend in the assembly direction from the main body section to the housing, and inside the pair of locking arms. Is provided with a protruding protruding locking portion for locking to the other surface side opposite to the one surface side of the outer surface of the housing.

本発明によれば、電線保持部材の係止部がハウジングの外面に係止するから、電線保持部材とハウジングとの係止状態を視認しやすい。また、係止部が一対の係止アームの内側に突出しているから、電線保持部材の本体部に組み付け方向と逆向きの力が加わって一対の係止アームが内側へ変位しても、係止部が外れる虞が無い。 According to the present invention, since the locking portion of the electric wire holding member is locked to the outer surface of the housing, it is easy to visually recognize the locked state between the electric wire holding member and the housing. In addition, since the locking portion protrudes inside the pair of locking arms, even if a force in the direction opposite to the assembly direction is applied to the body portion of the wire holding member and the pair of locking arms are displaced inward, There is no risk that the stop will come off.

本発明の好ましい形態を以下に示す。 Preferred embodiments of the present invention are shown below.

本発明のコネクタは、前記一対の係止アームが、前記ハウジングへの組み付け途中では外側に弾性撓みし、組み付け完了時には内側に弾性復帰するものとされ、前記ハウジングが、前記係止アームの弾性撓みを許容する撓み許容窓を有して、前記係止アームの外側に位置する外壁部を備えているものとしてもよい。 In the connector according to the present invention, the pair of locking arms are elastically bent outward during the assembly to the housing, and are elastically returned to the inner side when the assembly is completed, and the housing is elastically bent by the locking arm. It is good also as what is provided with the outer wall part located in the outer side of the said latching arm.

このような構成によれば、電線保持部材の組み付け途中には係止アームが撓み許容窓に入って弾性撓みし、組み付け完了時には係止アームが弾性復帰して外壁部の内側に位置するから、係止アームが外側に剥き出しになることを防いで、係止アームを保護することができる。 According to such a configuration, the locking arm enters the bending allowance window during the assembly of the electric wire holding member and elastically bends, and when the assembly is completed, the locking arm is elastically restored and located inside the outer wall portion. The locking arm can be protected by preventing the locking arm from being exposed to the outside.

また、本発明のコネクタは、前記ハウジングが、前記電線保持部材の組み付け途中においては前記係止部を前記他面側から覆い、前記電線保持部材の組み付け完了時においては前記係止部を前記他面側に開放する覆壁部を有しているものとしてもよい。 In the connector of the present invention, the housing covers the locking portion from the other surface side during the assembly of the electric wire holding member, and the assembly of the locking portion when the electric wire holding member is assembled. It is good also as what has the covering wall part opened to the surface side.

このような構成によれば、電線保持部材の組み付け途中では係止部が覆壁部に隠れ、組み付け完了時には係止部が覆壁部に隠れないで他面側から見えるから、係止部が他面側から見えるか否かで、係止部の係止状態を容易に確認することができる。 According to such a configuration, the latching portion is hidden by the cover wall during the assembly of the electric wire holding member, and when the assembly is completed, the latching portion is not hidden by the cover wall and can be seen from the other surface side. The locking state of the locking portion can be easily confirmed depending on whether it can be seen from the other surface side.

また、本発明のコネクタは、前記ハウジングが、前記キャビティのうち前記電線保持部材の本体部と対向する面に、凹凸形状をなす凹凸部を有しているものとしてもよい。このような構成によれば、凹凸部の突部が電線の絶縁被覆に食い込んだ状態になるので、電線の動きを確実に規制することができる。 In the connector according to the present invention, the housing may have a concavo-convex portion having a concavo-convex shape on a surface of the cavity facing the main body portion of the wire holding member. According to such a configuration, the protrusions of the concavo-convex portions are in a state of being engulfed in the insulating coating of the electric wires, so that the movement of the electric wires can be reliably regulated.

また、本発明のコネクタは、前記電線保持部材が、前記本体部のうち前記キャビティに臨む面に設けられた弾性部を有しているものとしてもよい。このような構成によれば、弾性部が強い摩擦力を生じることによって、電線の動きをより確実に規制することができる。 In the connector according to the present invention, the electric wire holding member may have an elastic portion provided on a surface of the main body portion facing the cavity. According to such a configuration, the movement of the electric wire can be more reliably restricted by the elastic portion generating a strong frictional force.

また、本発明のコネクタは、前記電線保持部材が、前記電線を包み込むような形状をなして前記電線を押さえる押え部を有しているものとしてもよい。このような構成によれば、押え部が、幅方向に電線を抑え込むことによって、電線の動きをより確実に抑制することができる。 Moreover, the connector of this invention is good also as what has the holding | suppressing part which makes the said electric wire holding member the shape which wraps the said electric wire, and hold | suppresses the said electric wire. According to such a configuration, the movement of the electric wire can be more reliably suppressed by the pressing portion holding the electric wire in the width direction.

After all the terminal fittings 10 are accommodated in the terminal accommodating portion 22, the electric wire holding member 40 is inserted into the assembling portion 24 from above. Then, as shown in FIG. 9, the locking portion 47 comes into contact with the upper end corner of the terminal accommodating portion 22, the locking arm 42 is elastically bent in an oblique posture, and the locking portion 47 of the locking arm 42 is accommodated in the terminal accommodating. It rides on the side surface of the portion 22 and is displaced outward, and the stopper portion 44 is displaced inward. During the assembly of the electric wire holding member 40, the locking portion 47 and the locking arm 42 are in a state where they enter the bending-permissible window 31, and when the connector C is viewed from below, as shown in FIG. The cover wall 26 is hidden from view.

電線保持部材４０を組付部２４にさらに侵入すると、図４に示すように、押え部４５がキャビティ２１の下面との間で電線Ｗを挟み付けて、押圧部４６が電線Ｗの絶縁被覆に食い込み、この食い込み作用によって電線Ｗの前後方向への移動が制限される。このときの押圧部４６の食い込み深さは、絶縁被覆が破れない程度の寸法に設定されている。 When the electric wire holding member 40 further enters the assembling portion 24, as shown in FIG. 4, the holding portion 45 sandwiches the electric wire W between the lower surface of the cavity 21, and the pressing portion 46 serves as an insulating coating for the electric wire W. The bite and the bite action limit the movement of the electric wire W in the front-rear direction. The biting depth of the pressing portion 46 at this time is set to a dimension that does not break the insulating coating.

また、図１１に示すように、係止部４７が段差部２７の位置に至って段差部２７に入り込み、係止アーム４２が弾性復帰して、係止部４７が係止受け部２８に係止した状態になるとともに、ストッパ部４４が上枠部３２の上面に係止した状態になる。これにより、電線保持部材４０は、上下方向の移動が制限され、組付部２４に対して正規の組み付け状態に保持される。このとき、コネクタＣを下方から見ると、図１０に示すように、係止受け部２８に係止した状態の係止部４７を、覆壁部２６の内側に見ることができるので、電線保持部材４０の組み付け作業が完了したことを知ることができる。また、弾性復帰した係止アーム４２は、図１１に示すように、端子収容部２２の側面に沿って外壁部２５の内側に収容されているから、係止アーム４２に異物が接触することを防ぐことができる。
以上により、電線保持部材４０をハウジング２０に組み付ける作業が完了する。 Further, as shown in FIG. 11, the locking portion 47 reaches the position of the stepped portion 27 and enters the stepped portion 27, the locking arm 42 is elastically restored, and the locking portion 47 is locked to the locking receiving portion 28. At the same time, the stopper portion 44 is locked to the upper surface of the upper frame portion 32. Thereby, the movement of the electric wire holding member 40 is restricted, and the electric wire holding member 40 is held in a regular assembled state with respect to the assembled portion 24. At this time, when the connector C is viewed from below, the locking portion 47 locked to the locking receiving portion 28 can be seen inside the cover wall portion 26 as shown in FIG. It can be known that the assembly operation of the member 40 has been completed. Further, as shown in FIG. 11, since the locking arm 42 that has returned to elasticity is accommodated inside the outer wall portion 25 along the side surface of the terminal accommodating portion 22, the foreign matter contacts the locking arm 42. Can be prevented.
Thus, the work for assembling the electric wire holding member 40 to the housing 20 is completed.

次に、上記のように構成された実施例１の作用および効果について説明する。
本実施例１のコネクタＣは、電線Ｗの端末部に接続された端子金具１０が収容されるキャビティ２１を有するハウジング２０と、ハウジング２０の上面側に組み付けられて電線Ｗの動きを抑制する電線保持部材４０と、を有している。電線保持部材４０は、キャビティ２１を幅方向に横切る本体部４１と、本体部４１からハウジング２０への組み付け方向に延出する一対の係止アーム４２と、を有し、一対の係止アーム４２の内側には、ハウジング２０の下側に係止する係止部４７が突出して設けられている。この構成によれば、電線保持部材４０の係止部４７がハウジング２０の下面に係止するから、電線保持部材４０とハウジング２０との係止状態を視認しやすい。また、係止部４７が一対の係止アーム４２の内側に突出しているから、電線保持部材４０の本体部４１に組み付け方向と逆向きの力が加わって一対の係止アーム４２が内側へ変位しても、係止部４７が外れる虞が無い。したがって、本実施例のコネクタＣによれば、電線保持部材４０とハウジング２０との係止状態を容易に確認することができ、またハウジング２０に対する電線保持部材４０の係止力を向上することができる。 Next, operations and effects of the first embodiment configured as described above will be described.
The connector C according to the first embodiment includes a housing 20 having a cavity 21 in which a terminal fitting 10 connected to a terminal portion of an electric wire W is accommodated, and an electric wire that is assembled on the upper surface side of the housing 20 and suppresses the movement of the electric wire W. Holding member 40. The electric wire holding member 40 includes a main body portion 41 that crosses the cavity 21 in the width direction, and a pair of locking arms 42 that extend in the assembly direction from the main body portion 41 to the housing 20, and the pair of locking arms 42. A locking portion 47 that locks to the lower side of the housing 20 protrudes from the inside of the housing 20. According to this configuration, since the locking portion 47 of the electric wire holding member 40 is locked to the lower surface of the housing 20, it is easy to visually recognize the locked state between the electric wire holding member 40 and the housing 20. Moreover, since the latching | locking part 47 protrudes inside a pair of latching arm 42, the force opposite to an assembly direction is added to the main-body part 41 of the electric wire holding member 40, and a pair of latching arm 42 displaces inside. Even so, there is no possibility that the locking portion 47 will come off. Therefore, according to the connector C of the present embodiment, it is possible to easily confirm the locking state between the wire holding member 40 and the housing 20 and to improve the locking force of the wire holding member 40 with respect to the housing 20. it can.

また、一対の係止アーム４２が、ハウジング２０への組み付け途中では外側に弾性撓みし、組み付け完了時には内側に弾性復帰するものとされ、ハウジング２０が、係止アーム４２の弾性撓みを許容する撓み許容窓３１を有して、係止アーム４２の外側に位置する外壁部２５を備えている。この構成によれば、電線保持部材４０の組み付け途中には係止アーム４２が撓み許容窓３１に入って弾性撓みし、組み付け完了時には係止アーム４２が弾性復帰して外壁部２５の内側に位置するから、係止アーム４２が外側に剥き出しになることを防ぐことができる。 Further, the pair of locking arms 42 are elastically bent outward during the assembly to the housing 20 and are elastically returned to the inner side when the assembly is completed, and the housing 20 is bent to allow the elastic deformation of the locking arms 42. The outer wall part 25 which has the permissible window 31 and is located outside the locking arm 42 is provided. According to this configuration, during the assembly of the wire holding member 40, the locking arm 42 enters the bending allowance window 31 and elastically bends, and when the assembly is completed, the locking arm 42 returns elastically and is positioned inside the outer wall portion 25. Therefore, it is possible to prevent the locking arm 42 from being exposed to the outside.

また、ハウジング２０が、電線保持部材４０の組み付け途中においては係止部４７を下面側から覆い、電線保持部材４０の組み付け完了時においては係止部４７を下面側に開放する覆壁部２６を有している。この構成によれば、電線保持部材４０の組み付け途中では係止部４７が覆壁部２６に隠れ、組み付け完了時には係止部４７が覆壁部２６に隠れないで下面側から見えるから、係止部４７が下面側から見えるか否かで、係止部４７の係止状態を容易に確認することができる。 Further, the housing 20 covers the locking portion 47 from the lower surface side during the assembly of the electric wire holding member 40, and the covering wall portion 26 that opens the locking portion 47 to the lower surface side when the electric wire holding member 40 is assembled. Have. According to this configuration, the latching portion 47 is hidden by the cover wall portion 26 during the assembly of the electric wire holding member 40, and when the assembly is completed, the latching portion 47 is visible from the lower surface side without being hidden by the cover wall portion 26. The locking state of the locking part 47 can be easily confirmed by whether or not the part 47 is visible from the lower surface side.

The connector 70 of the present embodiment is different from the first embodiment in that the connector 70 of the present embodiment has an elastic portion 71 on the surface (lower surface) facing the cavity 21 of the main body 41. In addition, the same code | symbol is attached | subjected to the structure similar to Example 1, and the overlapping description is abbreviate | omitted.

本実施例に係るコネクタ７０は、実施例１と同様に、電線Ｗの端末部に接続された端子金具１０が収容されるキャビティ２１を有するハウジング２０と、ハウジング２０の上面側に組み付けられて電線Ｗの動きを抑制する電線保持部材４０と、を有し、電線保持部材４０が、キャビティ２１を幅方向に横切る本体部４１と、本体部４１からハウジング２０への組み付け方向に延出する一対の係止アーム４２と、を有し、一対の係止アーム４２の内側に、ハウジング２０の下面側に係止する係止部４７が突出して設けられている。 Similar to the first embodiment, the connector 70 according to the present embodiment includes a housing 20 having a cavity 21 in which the terminal fitting 10 connected to the terminal portion of the electric wire W is accommodated, and an upper surface side of the housing 20 so that the electric wire is assembled.

各押え部８１の下面は、電線Ｗを包み込むような形状に形成されている。押え部８１の下面には、幅方向の中心から端に向かって次第に下がる（下方への突出寸法が増す）一対の傾斜面８２が形成されている。一対の傾斜面８２は、押え部８１の幅方向における中心を基準にして左右対称な形状をなしている。電線保持部材４０をハウジング２０に組み付けた状態では、押え部８１の各傾斜面８２が電線Ｗに接触し、電線Ｗを左右から押さえ込んだ状態になる。 The lower surface of each pressing portion 81 is formed in a shape that encloses the electric wire W. A pair of inclined surfaces 82 are formed on the lower surface of the pressing portion 81 so as to gradually descend from the center in the width direction toward the end (increase in the downward projecting dimension). The pair of inclined surfaces 82 has a symmetrical shape with respect to the center in the width direction of the presser portion 81. In a state where the electric wire holding member 40 is assembled to the housing 20, each inclined surface 82 of the holding portion 81 comes into contact with the electric wire W, and the electric wire W is pressed from the left and right.

以上のように本実施例においては、実施例１と同様、電線保持部材４０の係止部４７がハウジング２０の下面に係止するから、電線保持部材４０とハウジング２０との係止状態を視認しやすく、また、係止部４７が一対の係止アーム４２の内側に突出しているから、電線保持部材４０の本体部４１に組み付け方向と逆向きの力が加わって係止アーム４２が内側へ変位しても、係止部４７が外れる虞が無い。さらに、押え部８１の下面が、電線Ｗを包み込むような形状になっているから、幅方向の２点で電線Ｗを抑え込むことによって、電線Ｗの動きをより確実に抑制することができる。 As described above, in this embodiment, since the locking portion 47 of the wire holding member 40 is locked to the lower surface of the housing 20 as in the first embodiment, the locking state between the wire holding member 40 and the housing 20 is visually recognized. In addition, since the locking portion 47 protrudes inside the pair of locking arms 42, a force in the direction opposite to the assembly direction is applied to the main body portion 41 of the electric wire holding member 40 so that the locking arm 42 moves inward. Even if it is displaced, there is no possibility that the locking portion 47 comes off. Furthermore, since the lower surface of the pressing portion 81 is shaped to wrap the electric wire W, the movement of the electric wire W can be more reliably suppressed by suppressing the electric wire W at two points in the width direction.
