雄タブ２４は、図５に示すように、断面Ｕ字状に形成されている。雄タブ２４は、厚み方向Ｚの厚みＴ１が縮小するように弾性変形自在となっている。雄タブ２４の弾性変形していない中立状態での厚み方向Ｚの厚みＴ１は、前述した導入口２５の厚みＤ１と等しく、弾性変形していない中立状態での一対の接触片１９間の間隔Ｄ２より大きい。   As shown in FIG. 5, the male tab 24 has a U-shaped cross section. The male tab 24 is elastically deformable so that the thickness T1 in the thickness direction Z is reduced. The thickness T1 in the thickness direction Z in the neutral state where the male tab 24 is not elastically deformed is equal to the thickness D1 of the introduction port 25 described above, and the distance D2 between the pair of contact pieces 19 in the neutral state where the male tab 24 is not elastically deformed. Greater than.

前述した構成の雄端子２３は、コネクタハウジング２と嵌合する図示しない相手側のコネクタのコネクタハウジング内に収容される。   The male terminal 23 having the above-described configuration is accommodated in a connector housing of a mating connector (not shown) that fits into the connector housing 2.

前述した構成のコネクタ１を組み立てる際には、まず、内側筒状部１７の外側に外側押圧部材１６を嵌合させる。そして、雌端子３の電線接続部１０に電線４を取り付ける。そして、雌端子３を、外側押圧部材１６即ち電気接触部１１から端子収容室５内に挿入する。すると、押圧片２８が、前述したように傾斜した先端部２８ａからコネクタハウジング２の端子収容室５内に挿入される。   When assembling the connector 1 having the above-described configuration, first, the outer pressing member 16 is fitted to the outer side of the inner cylindrical portion 17. Then, the electric wire 4 is attached to the electric wire connecting portion 10 of the female terminal 3. Then, the female terminal 3 is inserted into the terminal accommodating chamber 5 from the outer pressing member 16, that is, the electric contact portion 11. Then, the pressing piece 28 is inserted into the terminal accommodating chamber 5 of the connector housing 2 from the tip portion 28a inclined as described above.

そして、押圧片２８の中央部が端子収容室５の内面から押圧されて、一対の押圧片２８が互いに近づく方向に、該押圧片２８が弾性変形する。すると、押圧片２８は、厚み方向Ｚ即ち雄タブ２４の長手方向に直交する方向に沿って、端子収容室５の内面を押圧する。さらに、雌端子３を端子収容室５の奥に挿入すると、係止片が前述した他方に係止する。このように、全ての端子収容室５に雌端子３を挿入して、前述した構成のコネクタ１を組み立てる。   And the center part of the press piece 28 is pressed from the inner surface of the terminal accommodating chamber 5, and this press piece 28 elastically deforms in the direction where a pair of press piece 28 approaches mutually. Then, the pressing piece 28 presses the inner surface of the terminal accommodating chamber 5 along the thickness direction Z, that is, the direction orthogonal to the longitudinal direction of the male tab 24. Further, when the female terminal 3 is inserted into the interior of the terminal accommodating chamber 5, the locking piece is locked to the other described above. In this way, the female terminals 3 are inserted into all the terminal accommodating chambers 5 to assemble the connector 1 having the above-described configuration.

一方、電線接続部１０に電線４が取り付けられた雄端子２３を、図示しない相手側のコネクタのコネクタハウジングの端子収容室内に挿入する。前述した相手側のコネクタを組み立てる。   On the other hand, the male terminal 23 having the electric wire 4 attached to the electric wire connecting portion 10 is inserted into the terminal accommodating chamber of the connector housing of the mating connector (not shown). Assemble the connector on the other side.

そして、コネクタ１が相手側のコネクタのコネクタハウジング内に侵入するように、コネクタ１と相手側のコネクタとを徐々に近づける。すると、図９に示すように、雄タブ２４がコネクタ１の端子収容室５内に徐々に侵入し、該雄タブ２４が雌端子３の電気接触部１１の導入口２５を通って、一対の接触片１９間に侵入する。すると、一対の接触片１９が互いに離れる方向に弾性変形するとともに、厚みが減少する方向に雄タブ２４が弾性変形する。すると、一対の接触片１９は、互いに近づく方向の弾性復元力を生じて、一対の接触片１９間に雄タブ２４を挟み込む。   Then, the connector 1 and the mating connector are gradually brought closer so that the connector 1 enters the connector housing of the mating connector. Then, as shown in FIG. 9, the male tab 24 gradually enters the terminal accommodating chamber 5 of the connector 1, and the male tab 24 passes through the inlet 25 of the electrical contact portion 11 of the female terminal 3, It enters between the contact pieces 19. Then, the pair of contact pieces 19 are elastically deformed in a direction away from each other, and the male tab 24 is elastically deformed in a direction in which the thickness is reduced. Then, the pair of contact pieces 19 generate an elastic restoring force in a direction approaching each other, and the male tab 24 is sandwiched between the pair of contact pieces 19.

そして、ロックアーム６が相手側のコネクタのコネクタハウジングに嵌合する。こうして、コネクタ１は、相手側のコネクタと嵌合して、雌端子３が雄端子２３と電気的及び機械的に接続する。   Then, the lock arm 6 is fitted into the connector housing of the mating connector. Thus, the connector 1 is engaged with the mating connector, and the female terminal 3 is electrically and mechanically connected to the male terminal 23.

本実施形態によれば、押圧片２８が雄タブ２４即ち端子収容室５の長手方向に直交する方向に沿って、端子収容室５の内面を押圧する。このため、雌端子３は、端子収容室５内に収容されると、特に雄タブ２４即ち端子収容室５の長手方向に直交する方向に沿って、移動することが規制される。   According to the present embodiment, the pressing piece 28 presses the inner surface of the terminal accommodating chamber 5 along the direction perpendicular to the male tab 24, that is, the longitudinal direction of the terminal accommodating chamber 5. For this reason, when the female terminal 3 is accommodated in the terminal accommodating chamber 5, movement of the female terminal 3 is restricted particularly along the direction orthogonal to the longitudinal direction of the male tab 24, that is, the terminal accommodating chamber 5.

このため、雌端子３が、コネクタハウジング２内で該コネクタハウジング２に対して相対的に振動（移動）することを防止でき、雌端子３と雄端子２３との電気的な接続を安定させることができる。   For this reason, it is possible to prevent the female terminal 3 from vibrating (moving) relative to the connector housing 2 in the connector housing 2, and to stabilize the electrical connection between the female terminal 3 and the male terminal 23. Can do.

押圧片２８が、接点としての接触凸部２６と、雄タブ２４即ち端子収容室５の長手方向に直交する方向に沿って並設されているので、接触凸部２６が特に雄タブ２４即ち端子収容室５の長手方向に直交する方向に沿って、移動することを確実に規制できる。このため、雌端子３と雄端子２３との接点がコネクタハウジング２に対して相対的に振動（移動）することを規制でき、雌端子３と雄端子２３との電気的な接続を安定させることができる。   Since the pressing piece 28 is juxtaposed along the contact projection 26 as a contact point and the male tab 24, that is, along the direction orthogonal to the longitudinal direction of the terminal accommodating chamber 5, the contact projection 26 particularly has the male tab 24, that is, the terminal. Movement along the direction perpendicular to the longitudinal direction of the storage chamber 5 can be reliably restricted. For this reason, it is possible to restrict the contact between the female terminal 3 and the male terminal 23 from vibrating (moving) relative to the connector housing 2, and to stabilize the electrical connection between the female terminal 3 and the male terminal 23. Can do.

押圧片２８が一対設けられ、これら一対の押圧片２８間に接点としての接触凸部２６が位置付けられているので、接触凸部２６が特に雄タブ２４即ち端子収容室５の長手方向に直交する方向に沿って、移動することをより確実に規制できる。   Since a pair of pressing pieces 28 are provided and the contact convex portion 26 as a contact point is positioned between the pair of pressing pieces 28, the contact convex portion 26 is particularly orthogonal to the longitudinal direction of the male tab 24, that is, the terminal accommodating chamber 5. It is possible to more reliably regulate movement along the direction.

長手方向の両端が筒状部２７に連なり長手方向の中央部が端子収容室５の内面を押圧するので、押圧片２８が、端子収容室５の内面を、雄タブ２４即ち端子収容室５の長手方向に直交する方向に沿って、確実に押圧できる。   Since both ends in the longitudinal direction are connected to the cylindrical portion 27 and the central portion in the longitudinal direction presses the inner surface of the terminal accommodating chamber 5, the pressing piece 28 pushes the inner surface of the terminal accommodating chamber 5 into the male tab 24, that is, the terminal accommodating chamber 5. It can be reliably pressed along the direction orthogonal to the longitudinal direction.

押圧片２８の長手方向が雄タブ２４即ち端子収容室５の長手方向と平行なので、雌端子３を端子収容室５に挿入する際に、押圧片２８が端子収容室５の内面などに引っ掛かることを防止できる。このため、雌端子３を容易にコネクタハウジング２内に挿入できる。   Since the longitudinal direction of the pressing piece 28 is parallel to the longitudinal direction of the male tab 24, that is, the terminal accommodating chamber 5, when the female terminal 3 is inserted into the terminal accommodating chamber 5, the pressing piece 28 is caught on the inner surface of the terminal accommodating chamber 5. Can be prevented. For this reason, the female terminal 3 can be easily inserted into the connector housing 2.

雌端子３の導入片１８間の間隔Ｄ１が雄タブ２４の厚みＴ１と等しいので、雌端子３の内側接触部１５内に侵入した雄タブ２４が、雌端子３に対して移動することが確実に規制される。   Since the distance D1 between the introduction pieces 18 of the female terminal 3 is equal to the thickness T1 of the male tab 24, it is certain that the male tab 24 that has entered the inner contact portion 15 of the female terminal 3 moves relative to the female terminal 3. Regulated by

さらに、雄タブ２４が弾性変形自在であるので、雌端子３をコネクタハウジング２に移動することなく固定して、部材間に公差が生じても、雄タブ２４を雌端子３の電気接触部１１の筒部３２内に確実に挿入でき、雄端子２３と雌端子３とを確実に接続できる。   Furthermore, since the male tab 24 is elastically deformable, even if the female terminal 3 is fixed to the connector housing 2 without being moved and a tolerance is generated between the members, the male tab 24 is connected to the electrical contact portion 11 of the female terminal 3. The male terminal 23 and the female terminal 3 can be reliably connected to each other.

前述した実施形態では、押圧片２８を外側押圧部材１６の筒状部２７の底板２９と天井板３１との双方に設けている。しかしながら、本発明では、図１０ないし図１２に示すように、押圧片２８を外側押圧部材１６の筒状部２７の一対の側板３０に設けても良い。なお、図１０ないし図１２において、前述した実施形態と同一部分には、同一符号を付して説明を省略する。   In the embodiment described above, the pressing pieces 28 are provided on both the bottom plate 29 and the ceiling plate 31 of the cylindrical portion 27 of the outer pressing member 16. However, in the present invention, as shown in FIGS. 10 to 12, the pressing piece 28 may be provided on the pair of side plates 30 of the cylindrical portion 27 of the outer pressing member 16. 10 to 12, the same parts as those of the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

この場合においても、雌端子３は、図１０に示すように、電線接続部１０と電気接触部１１とを備え、電気接触部１１が、内側接触部１５と外側押圧部材１６とを備えている。   Also in this case, as shown in FIG. 10, the female terminal 3 includes an electric wire connecting portion 10 and an electric contact portion 11, and the electric contact portion 11 includes an inner contact portion 15 and an outer pressing member 16. .

また、押圧片２８の長手方向は、図１１及び図１２に示すように、前述した奥行き方向Ｙ即ち雄タブ２４と端子収容室５の長手方向と平行に配されている。さらに、一対の押圧片２８の外表面間の間隔Ｄ４即ち雌端子３の幅方向Ｘの幅Ｄ４は、端子収容室５の幅方向Ｘの寸法即ち幅Ｔ３より若干大きい。さらに、一対の押圧片２８は、雄タブ２４即ち端子収容室５の長手方向に直交する幅方向Ｘに沿って、接触凸部２６と並設されているとともに、互いの間に接触凸部２６を位置付けている。   Further, as shown in FIGS. 11 and 12, the longitudinal direction of the pressing piece 28 is arranged in parallel with the depth direction Y described above, that is, the longitudinal direction of the male tab 24 and the terminal accommodating chamber 5. Further, the distance D4 between the outer surfaces of the pair of pressing pieces 28, that is, the width D4 in the width direction X of the female terminal 3, is slightly larger than the dimension in the width direction X of the terminal accommodating chamber 5, that is, the width T3. Further, the pair of pressing pieces 28 are juxtaposed with the contact convex portion 26 along the width direction X orthogonal to the longitudinal direction of the male tab 24, that is, the terminal accommodating chamber 5, and the contact convex portion 26 between them. Is positioned.

これら図１０ないし図１２に示す場合においても、前述した実施形態と同様に、雌端子３を端子収容室５内に挿入すると、押圧片２８は、互いに近づく方向に弾性変形して、雄タブ２４即ち端子収容室５の長手方向に直交する方向に沿って、端子収容室５の内面を押圧する。   Also in the cases shown in FIGS. 10 to 12, as in the above-described embodiment, when the female terminal 3 is inserted into the terminal accommodating chamber 5, the pressing pieces 28 are elastically deformed in a direction approaching each other, and the male tab 24. That is, the inner surface of the terminal accommodating chamber 5 is pressed along a direction orthogonal to the longitudinal direction of the terminal accommodating chamber 5.

また、前述した図示例では、押圧片２８を一対設けている。しかしながら、本発明では、押圧片２８を少なくとも一つ備えていれば良い。要するに、本発明では、押圧片２８を底板２９と天井板３１と一対の側板３０とのうち少なくとも一つに設ければ良い。   In the illustrated example described above, a pair of pressing pieces 28 are provided. However, in the present invention, at least one pressing piece 28 may be provided. In short, in the present invention, the pressing piece 28 may be provided on at least one of the bottom plate 29, the ceiling plate 31, and the pair of side plates 30.

また、押圧片２８と接点としての接触凸部２６とを、雄タブ２４即ち端子収容室５の長手方向に直交する方向に沿って、並設している。しかしながら、本発明では、押圧片２８と接点としての接触凸部２６とを、雄タブ２４即ち端子収容室５の長手方向に直交する方向に沿って、並設しなくても良い。   Further, the pressing piece 28 and the contact convex portion 26 as a contact point are arranged side by side along a direction orthogonal to the longitudinal direction of the male tab 24, that is, the terminal accommodating chamber 5. However, in the present invention, the pressing piece 28 and the contact convex portion 26 as a contact may not be provided side by side along the direction perpendicular to the longitudinal direction of the male tab 24, that is, the terminal accommodating chamber 5.

さらに、押圧片２８の両端を筒状部２７に連ねることなく、押圧片２８の一端を筒状部２７に連ねても良い。要するに、押圧片２８を片持ちにしても良い。また、押圧片２８の長手方向を、雄タブ２４即ち端子収容室５の長手方向に交差させても良い。   Further, one end of the pressing piece 28 may be connected to the cylindrical portion 27 without connecting both ends of the pressing piece 28 to the cylindrical portion 27. In short, the pressing piece 28 may be cantilevered. Further, the longitudinal direction of the pressing piece 28 may intersect with the longitudinal direction of the male tab 24, that is, the terminal accommodating chamber 5.
