Description

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

従来、合成樹脂製のハウジング内にゴム栓を収容するコネクタとして、下記特許文献１に記載のものが知られている。このコネクタは、電線の端末に接続された端子と、端子を後方から収容するキャビティが設けられたハウジングと、ハウジングの後部に収容されたゴム栓とを備えて構成されている。そして、電線をゴム栓に設けられた挿通孔に液密状に挿通させることにより、キャビティ内へ後方から水などが浸入することを防いでいる。 Conventionally, a connector described in Patent Document 1 below is known as a connector for housing a rubber plug in a synthetic resin housing. This connector includes a terminal connected to the end of the electric wire, a housing provided with a cavity for receiving the terminal from the rear, and a rubber plug accommodated in the rear portion of the housing.

特開２００６−１９０５４９号公報JP 2006-190549 A

ところで、例えば、電線の芯線にアルミニウム合金を用いたアルミ電線に銅または銅合金からなる端子を圧着する場合、異種金属同士が接続された部分に電解質が介在すると、両金属の少なくとも一方が水中にイオンとして溶け込んで電気化学的反応により腐食が進行する電食が発生する。このため、ゴム栓の前後方向の長さ寸法を長くして、電線と端子との接続部分をゴム栓によって覆うことが検討されている。
ところが、ゴム栓はハウジングに比べて軟質であるため、ゴム栓が前後方向に長くなると、端子を挿入する際に、ゴム栓内において、ハウジングのキャビティに対する端子が傾いたり、端子が軸回りに回動する、いわゆるローリングしたりする虞があり、この場合には、端子がキャビティの開口縁部と当接して挿入できなくなってしまう。 By the way, for example, when crimping a terminal made of copper or a copper alloy to an aluminum electric wire using an aluminum alloy for the core wire of the electric wire, when an electrolyte is interposed in a portion where dissimilar metals are connected to each other, at least one of the two metals is in water. Electro-corrosion that dissolves as ions and undergoes corrosion by electrochemical reaction occurs. For this reason, it has been studied to lengthen the length of the rubber plug in the front-rear direction and cover the connecting portion between the electric wire and the terminal with the rubber plug.
However, since the rubber plug is softer than the housing, if the rubber plug becomes longer in the front-rear direction, when the terminal is inserted, the terminal with respect to the cavity of the housing is inclined in the rubber plug, or the terminal rotates around the axis. In this case, the terminal may come into contact with the opening edge of the cavity and cannot be inserted.

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、ハウジングのキャビティに端子が挿入可能であるか否か検知することを目的とする。 The present invention has been completed based on the above circumstances, and an object thereof is to detect whether or not a terminal can be inserted into a cavity of a housing.

上記の目的を達成するための手段として本発明は、コネクタであって、合成樹脂製のハウジングと、電線の端末に圧着された端子と、前記端子が後方から挿通されることで前記電線と前記端子とが圧着された部分を覆うゴム栓と、前記ハウジングに設けられ、前記端子を後方から収容する端子収容部と、前記ハウジングの前記端子収容部の後方に設けられ、前記ゴム栓を収容するゴム栓収容部と、前記ゴム栓収容部の前部に設けられ、前記端子が通過することで前記端子収容部に前記端子が進入可能な正規の姿勢であるか否かを検知する姿勢検知部とを備えているところに特徴を有する。
このような構成のコネクタによると、ゴム栓に挿通された端子が姿勢検知部を通過することにより端子収容部に端子が挿入可能であることを保証し、端子が姿勢検知部に当接するなど端子が姿勢保証部を通過できない場合には、端子が傾いたり、ローリングしたりするなど端子が不正な姿勢であることを検知することができる。これにより、端子が端子収容部の位置に達するまで、端子の姿勢が正規か否か不明とされる場合に比べて、雌端子を挿入する作業性を向上させることができる。 As a means for achieving the above object, the present invention is a connector, which is a housing made of synthetic resin, a terminal crimped to the end of an electric wire, and the electric wire and the electric wire by inserting the terminal from the rear. A rubber plug that covers a portion to which the terminal is crimped, a terminal accommodating portion that is provided in the housing and accommodates the terminal from the rear, and is provided behind the terminal accommodating portion of the housing and accommodates the rubber plug. A rubber plug housing portion and a posture detection portion that is provided at a front portion of the rubber plug housing portion and detects whether or not the terminal is in a normal posture that allows the terminal to enter the terminal housing portion by passing through the terminal. It has the feature in having.
According to the connector having such a configuration, it is ensured that the terminal inserted into the rubber plug passes through the posture detection unit, so that the terminal can be inserted into the terminal receiving unit, and the terminal comes into contact with the posture detection unit. If the terminal cannot pass through the posture assurance unit, it can be detected that the terminal is in an incorrect posture, for example, the terminal is tilted or rolled. Thereby, until the terminal reaches the position of the terminal accommodating portion, the workability of inserting the female terminal can be improved as compared with the case where it is unknown whether the terminal posture is normal or not.

本発明の実施の態様として、以下の構成が好ましい。
前記ハウジングおよび前記ゴム栓には、前記端子が複数挿入されるようになっており、前記姿勢検知部は、前記端子を個別に適合して挿通させる検知孔を有している構成としてもよい。
このような構成によると、検知孔によって端子毎に端子の姿勢を確認することができるので、例えば、複数の端子を一括して通過させることができる検知孔に比べて、端子の上下左右のずれを確実に検知することができる。 The following configuration is preferable as an embodiment of the present invention.
A plurality of the terminals may be inserted into the housing and the rubber plug, and the posture detection unit may have a detection hole through which the terminals are individually fitted and inserted.
According to such a configuration, since the attitude of the terminal can be confirmed for each terminal by the detection hole, for example, the vertical and horizontal shifts of the terminal compared to the detection hole that allows a plurality of terminals to pass through at once. Can be reliably detected.

前記ゴム栓は、前記端子の挿入方向と交差する方向に開口した開口部から前記ゴム栓収容部に収容されることで、前記ゴム栓収容部の前壁と前記ゴム栓収容部の後壁との間に適合して収容されるようになっており、前記ゴム栓収容部の前記前壁は、前記姿勢検知部である構成としてもよい。
このような構成によると、ゴム栓の前後方向のずれを規制する前壁を姿勢検知部として兼用することができる。これにより、ゴム栓の前後のずれを規制するずれ規制部(前壁)と姿勢検知部とを個別に設ける場合に比べて、雌ハウジングの構造を簡素化することができる。 The rubber plug is housed in the rubber plug housing portion from an opening that opens in a direction intersecting the insertion direction of the terminal, so that the front wall of the rubber plug housing portion and the rear wall of the rubber plug housing portion And the front wall of the rubber plug housing part may be the posture detection part.
According to such a configuration, the front wall that restricts the displacement of the rubber plug in the front-rear direction can also be used as the posture detection unit. As a result, the structure of the female housing can be simplified as compared with the case where the displacement restricting portion (front wall) and the posture detecting portion for restricting the displacement of the rubber plug before and after are provided separately.

前記端子を係止することで前記端子を前記端子収容部内に抜け止めするリテーナを備えており、前記リテーナには、前記開口部において前記ゴム栓に当接することで、前記ゴム栓収容部内において前記ゴム栓が前記端子の挿入方向と交差する方向にがたつくことを規制するゴム栓保持部が設けられている構成としてもよい。
ゴム栓がゴム栓収容部内において端子の挿入方向と交差する方向にがたつくと、ゴム栓に端子が挿通される際に、端子が挿入方向と交差する方向に位置ずれして不正な姿勢となってしまう。ところが、上記のような構成によると、ゴム栓保持部によってゴム栓がゴム栓収容部内でがたつくことを規制しているので、端子が挿入方向と交差する方向に位置ずれすることを抑制することができる。 The retainer is provided with a retainer for retaining the terminal in the terminal accommodating portion by locking the terminal, and the retainer contacts the rubber plug in the opening, thereby allowing the retainer to be in the rubber stopper accommodating portion. It is good also as a structure provided with the rubber stopper holding | maintenance part which controls that a rubber stopper rattles in the direction which cross | intersects the insertion direction of the said terminal.
If the rubber plug rattles in the direction that intersects the insertion direction of the terminal in the rubber plug housing, when the terminal is inserted through the rubber plug, the terminal is displaced in the direction that intersects the insertion direction, resulting in an incorrect posture. End up. However, according to the configuration as described above, the rubber plug holding part restricts the rubber plug from rattling in the rubber plug housing part, so that the terminal can be prevented from being displaced in the direction intersecting the insertion direction. it can.

前記ゴム栓保持部は、前記ゴム栓収容部の開口部から露出した前記ゴム栓の露出面全体を覆う板状に形成されている構成としてもよい。
このような構成によると、ゴム栓収容部の開口部から水などが浸入することを抑制することができ、ゴム栓内に水などが浸入することをさらに抑制することができる。 The rubber plug holding portion may be formed in a plate shape covering the entire exposed surface of the rubber plug exposed from the opening of the rubber plug housing portion.
According to such a structure, it can suppress that water etc. permeate from the opening part of a rubber stopper accommodating part, and can further suppress that water etc. permeate into a rubber stopper.

前記電線の芯線を構成する金属と、前記端子を構成する金属とが異なる構成としてもよい。
線の芯線を構成する金属と、端子を構成する金属とが異なる場合、電線の芯線と端子との双方に亘って電解質が付着すると、芯線または端子に電食が発生する虞があるため、例えば、ゴム栓によって芯線と端子とが接続された部分を端子の挿入方向に大きく覆う必要がある。つまり、ゴム栓が端子の挿入方向に大きくなるとゴム栓に端子を挿入する際に、端子が傾いたり、ローリングしたりする可能性が高くなることから、異種金属(芯線と端子)が接続された部分をゴム栓によって覆う場合に、特に有効である。 It is good also as a structure from which the metal which comprises the core wire of the said electric wire differs from the metal which comprises the said terminal.
If the metal that constitutes the core of the wire is different from the metal that constitutes the terminal, if the electrolyte adheres to both the core and the terminal of the wire, there is a risk of electrolytic corrosion occurring on the core or the terminal. The portion where the core wire and the terminal are connected by the rubber plug needs to be largely covered in the insertion direction of the terminal. In other words, if the rubber plug becomes larger in the terminal insertion direction, there is a higher possibility of the terminal tilting or rolling when the terminal is inserted into the rubber plug, so dissimilar metals (core wire and terminal) are connected. This is particularly effective when the portion is covered with a rubber stopper.

前記芯線がアルミニウム又はアルミニウム合金からなる構成としてもよい。
アルミニウム又はアルミニウム合金は銅や銅合金に比べて比重が小さいから、電線を軽量化できる。一方、アルミニウム又はアルミニウム合金は比較的イオン化傾向が高いため、電食が発生した場合に溶解しやすい。ところが、上記の構成によると、芯線と端子とはゴム栓によって覆われているから、芯線がアルミニウム又はアルミニウム合金からなる場合に特に有効である。 The core wire may be made of aluminum or an aluminum alloy.
Since the specific gravity of aluminum or aluminum alloy is smaller than that of copper or copper alloy, the weight of the electric wire can be reduced. On the other hand, since aluminum or aluminum alloy has a relatively high ionization tendency, it easily dissolves when electrolytic corrosion occurs. However, according to the above configuration, since the core wire and the terminal are covered with the rubber plug, it is particularly effective when the core wire is made of aluminum or an aluminum alloy.

本発明によれば、ハウジングのキャビティに端子が挿入可能であるか否か検知することができる。 According to the present invention, it is possible to detect whether or not a terminal can be inserted into the cavity of the housing.

Compared to the case where the rubber plug is exposed from the portion, water can be prevented from entering the rubber plug housing portion 32 from the lower opening 32B.

本実施形態の雌コネクタ１０は以上のような構成であって、続いて雌コネクタ１０の組立方法を簡単に説明し、続けて雌コネクタ１０の作用効果を説明する。
まず、図７および図８に示すように、雌ハウジング３０の下方にゴム栓６０とリテーナ５０とを配置し、ゴム栓収容部３２の下側開口部３２Ｂからゴム栓６０をゴム栓収容部３２内に挿入する。 The female connector 10 of the present embodiment is configured as described above. Next, a method for assembling the female connector 10 will be briefly described, and then the operational effects of the female connector 10 will be described.
First, as shown in FIGS. 7 and 8, the rubber plug 60 and the retainer 50 are disposed below the female housing 30, and the rubber plug 60 is inserted from the lower opening 32 B of the rubber plug housing portion 32. Insert inside.

ゴム栓６０がゴム栓収容部３２内の正規の位置に収容されると、図５および図６に示すように、ゴム栓６０はゴム栓収容部３２の前壁３７および後壁３８に対して前後方向に密着した状態となる。つまり、ゴム栓６０の前後方向の移動が前壁３７と後壁３８とによって規制され、ゴム栓６０が前後方向にがたつくことなくゴム栓収容部３２内に収容される。また、ゴム栓６０のゴム栓側キャビティ６１と、ゴム栓収容部３２の前壁３７の検知孔４０と、後壁３８の端子挿入孔４１とが前後方向に連通した状態となる。 When the rubber plug 60 is housed in a proper position in the rubber plug housing portion 32, the rubber plug 60 is located with respect to the front wall 37 and the rear wall 38 of the rubber plug housing portion 32 as shown in FIGS. It will be in the state where it was stuck in the direction of order. That is, the movement of the rubber plug 60 in the front-rear direction is restricted by the front wall 37 and the rear wall 38, and the rubber plug 60 is accommodated in the rubber plug accommodation portion 32 without rattling in the front-rear direction. In addition, the rubber plug-side cavity 61 of the rubber plug 60, the detection hole 40 of the front wall 37 of the rubber plug housing portion 32, and the terminal insertion hole 41 of the rear wall 38 are in communication with each other in the front-rear direction.

ところで、本実施形態のような前後方向に長尺なゴム栓をゴム栓収容部に対して後方からに挿入しようとすると、挿入ストロークが大きくなるため、ゴム栓収容部の内にゴム栓を挿入する途中で、ゴム栓がゴム栓収容部の内壁に引っかかるなどして、ゴム栓を挿入する作業性が低下したり、ゴム栓が前後方向に潰れた状態でゴム栓収容部内に収容されたりすることが懸念される。 By the way, if a rubber plug that is long in the front-rear direction as in the present embodiment is inserted into the rubber plug housing portion from the rear side, the insertion stroke becomes large, so the rubber plug is inserted into the rubber plug housing portion. During the process, the rubber plug is caught on the inner wall of the rubber plug housing part, so that the workability of inserting the rubber plug is lowered, or the rubber plug is housed in the rubber plug housing part in a state of being crushed in the front-rear direction. There is concern.

ところが、本実施形態によると、ゴム栓収容部３２内に前後方向に長尺なゴム栓６０を下方から収容することができるから、ゴム栓収容部内にゴム栓を後方から収容する場合に比べて、雌ハウジング３０内にゴム栓６０を収容する作業性を向上させることができる。また、ゴム栓６０が前後方向に潰れた状態でゴム栓収容部３２内に収容されることを防ぐことができる。 However, according to the present embodiment, the rubber plug 60 that is long in the front-rear direction can be accommodated in the rubber plug accommodating portion 32 from below, so that the rubber plug is accommodated in the rubber plug accommodating portion from behind. The workability of housing the rubber plug 60 in the female housing 30 can be improved. Further, the rubber plug 60 can be prevented from being housed in the rubber plug housing portion 32 in a state of being crushed in the front-rear direction.

ゴム栓６０がゴム栓収容部３２内の正規の位置に収容されたところで、リテーナ５０の抜け止め部５１を雌ハウジング３０のリテーナ挿入口３３に嵌合させる。すると、抜け止め部５１が仮係止位置に至ったところでリテーナ５０のロック片５２におけるロック爪５６が雌ハウジング３０の仮係止突起４２に対して上方から係止し、図５に示すように、抜け止め部５１が仮係止位置に保持された状態となる。 When the rubber plug 60 is housed in a proper position in the rubber plug housing portion 32, the retaining portion 51 of the retainer 50 is fitted into the retainer insertion port 33 of the female housing 30. Then, when the retaining portion 51 reaches the temporary locking position, the lock claw 56 of the lock piece 52 of the retainer 50 is locked from above with respect to the temporary locking protrusion 42 of the female housing 30, and as shown in FIG. Thus, the retaining portion 51 is held in the temporary locking position.

次に、アルミ電線Ｗの端末に接続された雌端子２０を後方から雌ハウジング３０に挿入する。
この挿入過程では、まず、ゴム栓収容部３２の後壁３８における端子挿入孔４１の誘い込み面４１Ａによって雌端子２０の先端が端子挿入孔４１に誘い込まれる。そして、雌端子２０の接続筒部２１が端子挿入孔４１を通過したところで、接続筒部２１の先端がゴム栓６０の電線密着部６４に当接し、接続筒部２１がゴム栓用リップ６４Ａと共にゴム栓密着部６４を押し退けることで接続筒部２１がゴム栓６０の覆い部６３の内部空間に配される。 Next, the female terminal 20 connected to the terminal of the aluminum electric wire W is inserted into the female housing 30 from the rear.
In this insertion process, first, the tip of the female terminal 20 is drawn into the terminal insertion hole 41 by the drawing surface 41A of the terminal insertion hole 41 in the rear wall 38 of the rubber plug housing portion 32. When the connecting tube portion 21 of the female terminal 20 passes through the terminal insertion hole 41, the tip of the connecting tube portion 21 abuts on the electric wire contact portion 64 of the rubber plug 60, and the connecting tube portion 21 together with the rubber plug lip 64A. The connecting tube portion 21 is disposed in the internal space of the cover portion 63 of the rubber plug 60 by pushing away the rubber plug close-contact portion 64.

続けて、雌端子２０を雌ハウジング３０内に挿入すると、接続筒部２１の先端が繋ぎ部密着部６２に当接し、接続筒部２１が繋ぎ部用リップ６２Ａと共に繋ぎ部密着部６２を押し退けることで、接続筒部２１の先端がゴム栓側キャビティ６１を通過し、接続筒部２１がゴム栓収容部３２における前壁３７の検知孔４０に進入する。また、接続筒部２１の先端が繋ぎ部密着部６２に当接するのとほぼ同じタイミングで、繋ぎ部２３の止水部材２８が電線密着部６４に当接し、止水部材２８が電線用リップ６４Ａと共にゴム栓密着部６４を押し退けることで、止水部材装着部２３Ａが覆い部６３の内部空間に配される。 Subsequently, when the female terminal 20 is inserted into the female housing 30, the tip of the connection tube portion 21 abuts on the connection portion contact portion 62, and the connection tube portion 21 pushes the connection portion contact portion 62 together with the connection portion lip 62 A. Thus, the distal end of the connection tube portion 21 passes through the rubber plug side cavity 61, and the connection tube portion 21 enters the detection hole 40 of the front wall 37 in the rubber plug housing portion 32. In addition, the water stop member 28 of the connecting portion 23 contacts the wire contact portion 64 at substantially the same timing as the tip of the connection tube portion 21 contacts the connection portion contact portion 62, and the water stop member 28 is connected to the wire lip 64A. At the same time, the water stopper member mounting portion 23 A is disposed in the internal space of the cover portion 63 by pushing the rubber plug close-up portion 64 away.

ところで、ゴム栓６０は、合成樹脂製の雌ハウジング３０などに比べると軟質であるため、本実施形態のようにゴム栓６０が前後方向に長尺であると、ゴム栓側キャビティ６１内に雌端子２０を挿入する最中で雌端子２０が傾いたり、ローリングしたりして雌端子２０が不正な姿勢となる場合がある。そして、不正な姿勢のまま雌端子２０を挿入し続けると、雌端子２０の先端がハウジング側キャビティ３５の開口縁に当接するなどして、雌端子２０をハウジング側キャビティ３５に挿入することができなくなってしまう。 Incidentally, since the rubber plug 60 is softer than the female housing 30 made of synthetic resin or the like, if the rubber plug 60 is long in the front-rear direction as in this embodiment, a female plug is formed in the rubber plug-side cavity 61. In the middle of inserting the terminal 20, the female terminal 20 may be tilted or rolled to cause the female terminal 20 to have an incorrect posture. If the female terminal 20 continues to be inserted in an unauthorized posture, the female terminal 20 can be inserted into the housing-side cavity 35 such that the tip of the female terminal 20 comes into contact with the opening edge of the housing-side cavity 35. It will disappear.

ところが、本実施形態によると、ゴム栓６０を通過した雌端子２０の接続筒部２１がゴム栓収容部３２における前壁３７の検知孔４０を通過することで、接続筒部２１の姿勢が正規の姿勢であると保証され、接続筒部２１をハウジング側キャビティ３５の開口縁に当接させることなく、接続筒部２１をハウジング側キャビティ３５に挿入することができる。
また、ゴム栓側キャビティ６１内において、雌端子２０が傾いたり、ローリングしたりするなど雌端子２０が不正な姿勢となった場合には、接続筒部２１の先端が前壁３７に当接し、雌端子２０がハウジング側キャビティ３５内に挿入できないことを予め検知することができる。これにより、雌端子２０が端子収容部３１の位置に達するまで雌端子２０の姿勢が正規か否か不明とされる場合に比べて、雌端子２０の姿勢を予め確認することができ、雌端子２０の組み付け作業性を向上させることができる。
また、本実施形態の検知孔４０は、接続筒部２１の正面形状とほぼ同じ形状とされているから、例えば、複数の端子を一括して通過させることで左右の位置ずれのみを検知することができる上下方向に大きな検知孔に比べて、雌端子２０の上下左右の位置ずれを確実に検知することができる。 However, according to the present embodiment, the connecting tube portion 21 of the female terminal 20 that has passed through the rubber plug 60 passes through the detection hole 40 of the front wall 37 in the rubber plug housing portion 32, so that the posture of the connecting tube portion 21 is normal. Thus, the connecting tube portion 21 can be inserted into the housing side cavity 35 without bringing the connecting tube portion 21 into contact with the opening edge of the housing side cavity 35.
In addition, in the rubber plug side cavity 61, when the female terminal 20 is in an incorrect posture such as tilting or rolling, the tip of the connecting tube portion 21 comes into contact with the front wall 37, It can be detected in advance that the female terminal 20 cannot be inserted into the housing-side cavity 35. Thereby, the posture of the female terminal 20 can be confirmed in advance as compared with the case where it is unknown whether the posture of the female terminal 20 is normal or not until the female terminal 20 reaches the position of the terminal accommodating portion 31. 20 assembly workability | operativity can be improved.
Moreover, since the detection hole 40 of this embodiment is made into the substantially same shape as the front shape of the connection cylinder part 21, for example, it detects only a position shift of right and left by letting a plurality of terminals pass collectively. Compared with a detection hole that is large in the vertical direction, the positional deviation of the female terminal 20 in the vertical and horizontal directions can be reliably detected.

接続筒部２１が検知孔４０を通過し、接続筒部２１がハウジング側キャビティ３５内に進入した後、さらに雌端子２０を雌ハウジング３０内に挿入する。すると、電線接続部２２のインシュレーションバレル部２５が電線密着部６４に当接し、インシュレーションバレル部２５が電線栓用リップ６４Ａと共に電線密着部６４を押し退けることで、電線接続部２２が覆い部６３の内部空間(ゴム栓側キャビティ６１の前後方向略中央部)に配される。また、繋ぎ部２３の止水部材装着部２３Ａが繋ぎ部密着部６２内に配され、電線接続部２２の後方に引き出されたアルミ電線Ｗが電線密着部６４内に配される。
つまり、繋ぎ部密着部６２の繋ぎ部用リップ６２Ａが止水部材装着部２３Ａの外周面に全周に亘って密着して繋ぎ部密着部６２の内周面と止水部材装着部２３Ａの外周面との間が液密状にシールされる。また、電線密着部６４の電線用リップ６４Ａがアルミ電線Ｗの外周面に全周に亘って密着して電線密着部６４の内周面とアルミ電線Ｗの外周面との間が液密状にシールされる。これにより、外部から浸入する水や塵埃が電線接続部２２に付着することを防止することができる。
すなわち、アルミ電線Ｗに用いられているアルミニウム又はアルミニウム合金は比較的イオン化傾向が高いため、電食が発生しやすいところ、本実施形態によると、電線接続部２２に水や塵埃が付着することを防止することができるから、アルミ電線Ｗと雌端子２０との接続部分で電食が発生することを防止することができる。また、アルミニウムまたはアルミニウム合金は、銅または銅合金よりも比重が小さいので、雌コネクタ１０を軽量化する際に、有効である。 After the connecting cylinder part 21 passes through the detection hole 40 and the connecting cylinder part 21 enters the housing side cavity 35, the female terminal 20 is further inserted into the female housing 30. Then, the insulation barrel portion 25 of the wire connection portion 22 contacts the wire contact portion 64, and the insulation barrel portion 25 pushes away the wire contact portion 64 together with the wire plug lip 64A, so that the wire connection portion 22 covers the cover portion 63. In the inner space (approximately the center in the front-rear direction of the rubber plug-side cavity 61). Further, the water stop member mounting portion 23 A of the connecting portion 23 is arranged in the connecting portion close contact portion 62, and the aluminum electric wire W drawn out behind the wire connecting portion 22 is disposed in the wire close contact portion 64.
That is, the connecting portion lip 62A of the connecting portion contact portion 62 is in close contact with the outer peripheral surface of the water stop member mounting portion 23A over the entire periphery, and the outer peripheral surface of the water stop member mounting portion 23A. The space is sealed in a liquid-tight manner. Further, the wire lip 64A of the wire contact portion 64 is in close contact with the outer peripheral surface of the aluminum wire W over the entire circumference so that the space between the inner peripheral surface of the wire contact portion 64 and the outer peripheral surface of the aluminum wire W is liquid-tight. Sealed. Thereby, it can prevent that the water and dust which permeate from the outside adhere to the electric wire connection part 22. FIG.
That is, since aluminum or aluminum alloy used for the aluminum electric wire W has a relatively high ionization tendency, electric corrosion is likely to occur. According to this embodiment, water or dust adheres to the electric wire connection portion 22. Since it can prevent, it can prevent that electric corrosion generate | occur | produces in the connection part of the aluminum electric wire W and the female terminal 20. FIG. In addition, since aluminum or aluminum alloy has a specific gravity smaller than that of copper or copper alloy, it is effective in reducing the weight of the female connector 10.

また、本実施形態によると、従来のようにアルミ電線と電線接続部とが接続された部分をモールドする必要がなく、隣り合う雌端子２０のピッチを変更する必要がない。これにより、図２０に示すように、既設の雄コネクタ７０との互換性を維持することができる。
そして、雌端子２０がハウジング側キャビティ３５の正規の位置まで挿入されると、接続筒部２１の係止部２１Ａにランス３６が係止することで、図５に示すように、雌端子２０が端子収容部３１に保持される。 Further, according to the present embodiment, it is not necessary to mold a portion where the aluminum electric wire and the electric wire connecting portion are connected as in the prior art, and it is not necessary to change the pitch of the adjacent female terminals 20. Thereby, as shown in FIG. 20, compatibility with the existing male connector 70 can be maintained.
Then, when the female terminal 20 is inserted to the proper position of the housing side cavity 35, the lance 36 is locked to the locking portion 21A of the connecting cylinder portion 21, so that the female terminal 20 is moved as shown in FIG. It is held in the terminal accommodating portion 31.

ところで、雌端子２０の接続筒部２１や電線接続部２２の外周寸法は、繋ぎ部２３やアルミ電線Ｗの外周寸法よりも大きいことから、仮に、ゴム栓側キャビティの内部空間全体が繋ぎ部密着部の内部空間や電線密着部の内部空間とほぼ同じ大きさに形成されている場合には、雌端子をゴム栓側キャビティ内に挿入する際に、接続筒部や電線接続部がゴム栓側キャビティの内壁に引っかかり、雌端子の挿入抵抗が高くなってしまう。また、ゴム栓側キャビティの内壁に接続筒部や電線接続部が引っかかったまま、雌端子を挿入すると、ゴム栓収容部内においてゴム栓が前後方向に潰れた状態となってしまう虞がある。 By the way, since the outer peripheral dimension of the connecting cylinder part 21 and the electric wire connecting part 22 of the female terminal 20 is larger than the outer peripheral dimension of the connecting part 23 and the aluminum electric wire W, the entire internal space of the rubber plug side cavity is temporarily connected. When the female terminal is inserted into the rubber plug side cavity, the connecting tube part and the wire connecting part are on the rubber plug side. The insertion resistance of the female terminal becomes high due to being caught by the inner wall of the cavity. Further, if the female terminal is inserted while the connecting tube portion or the wire connecting portion is caught on the inner wall of the rubber plug side cavity, the rubber plug may be crushed in the front-rear direction in the rubber plug housing portion.

ところが、本実施形態によると、覆い部６３の内部空間は、図５に示すように、繋ぎ部密着部６２の内部空間や電線密着部６４の内部空間よりも拡幅され、さらに覆い部６３の内部空間において最も拡幅された部分の内径寸法は接続筒部２１や電線接続部２２の外径寸法とほぼ同じ大きさに設定されている。これにより、接続筒部２１や電線接続部２２が覆い部６３内を通過する際に、接続筒部２１や電線接続部２２が覆い部６３に引っかかることを抑制することができる。すなわち、ゴム栓６０内に雌端子２０を挿入する際の挿入抵抗を低減させると共に、ゴム栓収容部３２内においてゴム栓６０が前後方向に潰れることを抑制することができる。 However, according to the present embodiment, as shown in FIG. 5, the internal space of the cover portion 63 is wider than the internal space of the connecting portion close contact portion 62 and the internal space of the wire close contact portion 64. The inner diameter dimension of the widest portion in the space is set to be approximately the same as the outer diameter dimension of the connection tube portion 21 and the wire connection portion 22. Thereby, when the connection cylinder part 21 and the electric wire connection part 22 pass the inside of the cover part 63, it can suppress that the connection cylinder part 21 and the electric wire connection part 22 are caught in the cover part 63. FIG. That is, it is possible to reduce the insertion resistance when the female terminal 20 is inserted into the rubber plug 60 and to prevent the rubber plug 60 from being crushed in the front-rear direction in the rubber plug housing portion 32.

そして、同様の手順によって全ての雌端子２０が雌ハウジング３０に挿入されたところで、リテーナ５０を上方に移動させる。すると、リテーナ５０のロック片５２におけるロック爪５６が雌ハウジング３０の本係止突起４３に上方から係止することで、抜け止め部５１が本係止位置に配され、図６に示すように、雌ハウジング３０内に挿入された全ての雌端子２０がランス３６と端子係止部５５とによって二重に係止される。また、これと同時に、リテーナ５０のゴム栓保持部５３がゴム栓６０の下面に密着すると共に、ゴム栓収容部３２の下側開口部３２Ｂを覆い、雌コネクタ１０が完成する。 Then, when all the female terminals 20 are inserted into the female housing 30 by the same procedure, the retainer 50 is moved upward. Then, the locking claw 56 in the locking piece 52 of the retainer 50 is locked to the main locking projection 43 of the female housing 30 from above, so that the retaining portion 51 is disposed at the final locking position, as shown in FIG. All the female terminals 20 inserted into the female housing 30 are doubly locked by the lance 36 and the terminal locking portion 55. At the same time, the rubber plug holding portion 53 of the retainer 50 is in close contact with the lower surface of the rubber plug 60 and covers the lower opening 32B of the rubber plug housing portion 32, whereby the female connector 10 is completed.

つまり、雌コネクタ１０が完成した際には、ゴム栓収容部３２内にゴム栓６０が上下方向にがたつくことなく収容され、ゴム栓収容部３２の下側開口部３２Ｂからゴム栓６０が露出しないようにゴム栓６０がゴム栓保持部５３によって覆われた状態となる。これにより、ゴム栓６０が上下方向にがたつくことに起因して雌端子２０が上下方向に位置ずれすることを抑制することができると共に、下側開口部３２Ｂから水や塵埃などがゴム栓収容部３２内に浸入することを抑制することができる。 That is, when the female connector 10 is completed, the rubber plug 60 is accommodated in the rubber plug accommodating portion 32 without rattling in the vertical direction, and the rubber plug 60 is not exposed from the lower opening 32B of the rubber plug accommodating portion 32. Thus, the rubber plug 60 is covered with the rubber plug holding portion 53. Accordingly, the female terminal 20 can be prevented from being displaced in the vertical direction due to the rubber plug 60 rattling in the vertical direction, and water, dust and the like can be removed from the lower opening 32B. It is possible to suppress intrusion into 32.

以上のように、本実施形態によると、ゴム栓６０のゴム栓側キャビティ６１内に雌端子２０を挿入すると、雌端子２０の電線接続部２２が覆い部６３に覆われる。また、電線接続部２２の前側において繋ぎ部密着部６２が繋ぎ部２３の止水部材装着部２３Ａに密着すると共に、電線接続部２２の後側において電線密着部６４がアルミ電線Ｗに密着するから、外部から侵入した水や塵埃などが電線接続部２２に付着することを防止することができる。
また、本実施形態によると、アルミ電線Ｗと電線接続部２２とが接続された部分をモールドする必要がなく、隣り合う雌端子２０のピッチを変更する必要がないから、既設の雄コネクタ７０との互換性を維持しつつ、アルミ電線Ｗと雌端子２０との接続部分の電食を防ぐことができる。 As described above, according to the present embodiment, when the female terminal 20 is inserted into the rubber plug-side cavity 61 of the rubber plug 60, the wire connecting portion 22 of the female terminal 20 is covered with the cover portion 63. In addition, the connecting portion contact portion 62 is in close contact with the water stop member mounting portion 23 A of the connecting portion 23 on the front side of the wire connecting portion 22, and the wire contact portion 64 is in close contact with the aluminum electric wire W on the rear side of the wire connecting portion 22. In addition, it is possible to prevent water, dust, and the like that have entered from the outside from adhering to the wire connection portion 22.
Moreover, according to this embodiment, since it is not necessary to mold the part to which the aluminum electric wire W and the electric wire connection part 22 were connected, and it is not necessary to change the pitch of the adjacent female terminal 20, the existing male connector 70 and The electrical corrosion of the connecting portion between the aluminum wire W and the female terminal 20 can be prevented while maintaining the compatibility.

また、本実施形態によると、ゴム栓６０を通過した雌端子２０の接続筒部２１がゴム栓収容部３２における前壁３７の検知孔４０を通過することで、端子収容部３１のハウジング側キャビティ３５に対して接続筒部２１が挿入可能であることを保証することができる。これにより、雌端子２０が端子収容部３１の位置に達するまで、雌端子２０の姿勢が正規か否か不明とされる場合に比べて、雌ハウジング３０に雌端子２０を組み付ける作業性を向上させることができる。
さらに、本実施形態によると、ゴム栓収容部３２内においてゴム栓６０が前後方向に位置ずれすることを規制する前壁３７に検知孔４０を設けることで、前壁３７を姿勢検知部として兼用させることができる。これにより、前壁３７とは別に姿勢検知部を別途設ける場合に比べて、雌ハウジング３０の構造を簡素化することができる。 In addition, according to the present embodiment, the connecting cylinder portion 21 of the female terminal 20 that has passed through the rubber plug 60 passes through the detection hole 40 of the front wall 37 in the rubber plug housing portion 32, so that the housing side cavity of the terminal housing portion 31. It can be assured that the connecting tube portion 21 can be inserted into 35. Thereby, until the female terminal 20 reaches the position of the terminal accommodating part 31, compared with the case where it is unknown whether the attitude | position of the female terminal 20 is regular, the workability | operativity which attaches the female terminal 20 to the female housing 30 is improved. be able to.
Furthermore, according to the present embodiment, the front wall 37 is also used as the posture detection unit by providing the detection hole 40 in the front wall 37 that restricts the positional displacement of the rubber plug 60 in the front-rear direction in the rubber plug housing part 32. Can be made. As a result, the structure of the female housing 30 can be simplified as compared with a case where a posture detection unit is provided separately from the front wall 37.
