　上記のような端子構造においては、振動を受けた場合等に、両端子が、雄端子の幅方向に沿う方向に相対的に摺動し、両端子の接触部分においてメッキが剥がれるといった、いわゆる微摺動摩耗を生じるおそれがある。これにより、雄端子と雌端子との電気的な接続信頼性が低下することが懸念される。 In the terminal structure as described above, when subjected to vibration, the two terminals slide relative to each other along the width direction of the male terminal, and the plating is peeled off at the contact portion of both terminals. May cause sliding wear. Thereby, we are anxious about the electrical connection reliability of a male terminal and a female terminal falling.
　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、雄端子との電気的な接続信頼性を確保できる雌端子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 an object thereof is to provide a female terminal that can ensure electrical connection reliability with a male terminal.

An intermediate side elastic piece arranged between the two, and a frictional force of the end side elastic piece with respect to the male terminal is designed to be larger than a frictional force of the intermediate side elastic piece with respect to the male terminal. .
　このような構成によれば、雄端子を、幅方向における両端部において、より強い保持力で保持することが可能となる。これにより、両端子が雄端子の幅方向に沿う方向に相対的に摺動し、微摺動摩耗が生じることを抑制でき、両端子の電気的な接続信頼性を確保できる。 According to such a configuration, the male terminal can be held with a stronger holding force at both ends in the width direction. Thereby, it can suppress that both terminals slide relatively in the direction along the width direction of a male terminal, and a fine sliding wear arises, and can ensure the electrical connection reliability of both terminals.
　「前記端部側弾性片の前記雄端子に対する摩擦力が、前記中間側弾性片の前記雄端子に対する摩擦力よりも大きく設計」するために、前記端部側弾性片の幅寸法が、前記中間側弾性片の幅寸法よりも大きく設計されていてもよい。 In order to “design the frictional force of the end-side elastic piece to the male terminal larger than the frictional force of the intermediate-side elastic piece to the male terminal”, the width dimension of the end-side elastic piece is set to the middle You may design larger than the width dimension of a side elastic piece.
　あるいは、前記端部側弾性片は、前記端部側弾性片の表面において前記雄端子と接触する領域の表面粗さが、前記中間側弾性片の表面において前記雄端子と接触する領域における表面粗さよりも大きくなるように粗面化されていてもよい。 Alternatively, the end-side elastic piece has a surface roughness in a region in contact with the male terminal on a surface of the end-side elastic piece, and a surface roughness in a region in contact with the male terminal on the surface of the intermediate-side elastic piece. You may roughen so that it may become larger than this.
　本発明によれば、雄端子との電気的な接続信頼性を確保できる雌端子を提供できる。 According to the present invention, it is possible to provide a female terminal that can ensure electrical connection reliability with the male terminal.

It is set small.
　筒部２１の後方には、バレル部３３が延設されている。このバレル部３３は、筒部２１における底壁２２の後端から後方に延びる底板部３４と、この底板部３４の両側縁から側方に延設された一対のワイヤーバレル３５とを備える。一対のワイヤーバレル３５は、電線Ｗの端末において絶縁被覆から露出した芯線が底板部３４に載置された状態で、芯線の外面に巻き付けられるようにして圧着される。 A barrel portion 33 is extended behind the cylindrical portion 21.

　上記のように構成された雌端子２０を、雄端子１０と接続する際には、雄端子１０の雄タブ１１を前方から筒部２１内に挿入する。雄端子１０は、第１弾性片２８と第２弾性片３１との間に進入し、第１弾性片２８と第２弾性片３１との隙間を押し広げながら奥方へ進んでいく。雄タブ１１に押圧されることにより、第１弾性片２８は下方に弾性変形し、第２弾性片３１は上方に弾性変形する。雄タブ１１が正規位置まで押し込まれると、第１弾性片２８の第１接点部２９、および第２弾性片３１の第２接点部３２によって雄タブ１１が上下から挟み込まれた状態となる。そして、第１弾性片２８および第２弾性片３１の弾性復元力によって、第１接点部２９および第２接点部２９が適正な接触圧で雄タブ１１に押し付けられる。これにより、雄端子１０と雌端子２０とが電気的に接続される。 When the female terminal 20 configured as described above is connected to the male terminal 10, the male tab 11 of the male terminal 10 is inserted into the cylindrical portion 21 from the front. The male terminal 10 enters between the first elastic piece 28 and the second elastic piece 31, and advances toward the back while expanding the gap between the first elastic piece 28 and the second elastic piece 31. When pressed by the male tab 11, the first elastic piece 28 is elastically deformed downward, and the second elastic piece 31 is elastically deformed upward. When the male tab 11 is pushed to the normal position, the male tab 11 is sandwiched from above and below by the first contact portion 29 of the first elastic piece 28 and the second contact portion 32 of the second elastic piece 31. Then, by the elastic restoring force of the first elastic piece 28 and the second elastic piece 31, the first contact portion 29 and the second contact portion 29 are pressed against the male tab 11 with an appropriate contact pressure. Thereby, the male terminal 10 and the female terminal 20 are electrically connected.
　ここで、本実施形態の雌端子２０においては、端部側第１弾性片２８Ａおよび端部側第２弾性片３１Ａの幅寸法が、中間側第１弾性片２８Ｂおよび中間側第２弾性片３１Ｂの幅寸法よりも大きく設計されている。このため、雄タブ１１は、幅方向の両端部において、幅広に形成された端部側第１弾性片２８Ａと端部側第２弾性片３１Ａとで保持されることとなり、幅方向の両端において強い保持力で保持されることとなる。これにより、両端子１０、２０が雄端子１０の幅方向に沿う方向に相対的に摺動し、微摺動摩耗が生じることが抑制され、両端子１０、２０の電気的な接続信頼性の低下が抑制される。 Here, in the female terminal 20 of this embodiment, the width dimensions of the end-side first elastic piece 28A and the end-side second elastic piece 31A are such that the intermediate-side first elastic piece 28B and the intermediate-side second elastic piece 31B. Designed to be larger than the width dimension. For this reason, the male tab 11 is held by the end-side first elastic piece 28A and the end-side second elastic piece 31A formed wide at both ends in the width direction, and at both ends in the width direction. It will be held with a strong holding force. Thereby, both the terminals 10 and 20 are relatively slid in the direction along the width direction of the male terminal 10 and the occurrence of fine sliding wear is suppressed, and the electrical connection reliability of the both terminals 10 and 20 is reduced. Reduction is suppressed.
　以上のように本実施形態の雌端子２０は、雄端子１０を挿入可能な筒部２１と、この筒部２１の内部に設けられ、筒部２１内に挿入された雄端子１０に弾性的に接触する第１弾性片２８、第２弾性片３１を備えている。これらの第１弾性片２８、第２弾性片３１は、それぞれ、筒部２１内に挿入された状態の雄端子１０の幅方向に沿う並列方向に３本ずつ並列されている。 As described above, the female terminal 20 of the present embodiment is elastically attached to the cylindrical portion 21 into which the male terminal 10 can be inserted and the male terminal 10 provided in the cylindrical portion 21 and inserted into the cylindrical portion 21. A first elastic piece 28 and a second elastic piece 31 are provided. Each of the first elastic piece 28 and the second elastic piece 31 is arranged in parallel in a parallel direction along the width direction of the male terminal 10 inserted into the cylindrical portion 21.
　３本の第１弾性片２８は、並列方向の両端に配される一対の端部側第１弾性片２８Ａと、これら一対の端部側第１弾性片２８Ａの間に配される中間側第１弾性片２８Ｂとで構成される。そして、端部側第１弾性片２８Ａの幅寸法が、中間側第１弾性片２８Ｂの幅寸法よりも大きく設計されている。同様に、３本の第２弾性片３１は、並列方向の両端に配される一対の端部側第２弾性片３１Ａと、これら一対の端部側第２弾性片３１Ａの間に配される中間側第２弾性片３１Ｂとで構成される。そして、端部側第２弾性片３１Ａの幅寸法が、中間側第２弾性片３１Ｂの幅寸法よりも大きく設計されている。これにより、端部側第１弾性片２８Ａおよび端部側第２弾性片３１Ｂの雄タブ１１に対する摩擦力が、中間側第１弾性片２８Ｂおよび中間側第２弾性片３１Ｂの雄タブ１１に対する摩擦力よりも大きくなるように設計されている。 The three first elastic pieces 28 include a pair of end-side first elastic pieces 28A disposed at both ends in the parallel direction and an intermediate-side first elastic piece 28A disposed between the pair of end-side first elastic pieces 28A. 1 elastic piece 28B. The width dimension of the end-side first elastic piece 28A is designed to be larger than the width dimension of the intermediate-side first elastic piece 28B. Similarly, the three second elastic pieces 31 are arranged between a pair of end-side second elastic pieces 31A arranged at both ends in the parallel direction and the pair of end-side second elastic pieces 31A. It is comprised with the intermediate | middle side 2nd elastic piece 31B. The width of the end-side second elastic piece 31A is designed to be larger than the width of the intermediate-side second elastic piece 31B. As a result, the frictional force on the male tab 11 of the end-side first elastic piece 28A and the end-side second elastic piece 31B becomes the friction of the intermediate-side first elastic piece 28B and the intermediate-side second elastic piece 31B on the male tab 11. Designed to be greater than force.
　このような構成によれば、雄端子１０を、幅方向における両端部において、より強い保持力で保持することが可能となる。これにより、両端子１０、２０が雄端子１０の幅方向に沿う方向に相対的に摺動し、微摺動摩耗が生じることを抑制でき、両端子１０、２０の電気的な接続信頼性を確保できる。 According to such a configuration, the male terminal 10 can be held with a stronger holding force at both ends in the width direction. Thereby, it can suppress that both terminals 10 and 20 slide relatively in the direction along the width direction of the male terminal 10, and a fine sliding wear arises, and the electrical connection reliability of both the terminals 10 and 20 can be suppressed. It can be secured.
　＜変形例＞
　次に、変形例の雌端子４０について、図９を参照しつつ説明する。本変形例では、端部側弾性片の表面が粗面化された例を示す。なお、上記実施形態と同様の構成には同一の符号を付して説明を省略する。 <Modification>
Next, a modified female terminal 40 will be described with reference to FIG. In this modification, an example in which the surface of the end-side elastic piece is roughened is shown. In addition, the same code | symbol is attached | subjected to the structure similar to the said embodiment, and description is abbreviate | omitted.
　本変形例の雌端子４０は、上記実施形態と同様に、雄端子１０の雄タブ１１が挿入される筒部２１を備え、筒部２１の内部には、第１弾性片４１および第２弾性片４３が設けられている。第１弾性片４１および第２弾性片４３は、上記実施形態と同様の形状に形成されており、雄タブ１１と接触する第１接点部４２および第２接点部４４を備えている。 Similar to the above embodiment, the female terminal 40 of the present modification includes a cylindrical portion 21 into which the male tab 11 of the male terminal 10 is inserted. Inside the cylindrical portion 21, the first elastic piece 41 and the second elastic piece 41 are provided. A piece 43 is provided. The first elastic piece 41 and the second elastic piece 43 are formed in the same shape as in the above embodiment, and include a first contact portion 42 and a second contact portion 44 that contact the male tab 11.
　３本の第１弾性片４１のうち、両端に配される一対の第１弾性片４１は、端部側第１弾性片４１Ａとされ、これら一対の端部側第１弾性片４１Ａの間に配される第１弾性片４１は、中間側第１弾性片４１Ｂとされている。 Of the three first elastic pieces 41, the pair of first elastic pieces 41 arranged at both ends are the end-side first elastic pieces 41A, and between the pair of end-side first elastic pieces 41A. The arranged first elastic piece 41 is an intermediate first elastic piece 41B.
　端部側第１弾性片４１Ａの上面（雄タブ１１と対向する側の面）において、第１接点部４２の周辺領域は、粗面化処理が施されることにより粗面化されている。一方、中間側第１弾性片４１Ｂの表面は、粗面化処理が施されていない平滑な表面となっている。これにより、端部側第１弾性片４１Ａは、その表面において第１接点部４２の周辺領域（雄端子１０と接触する領域）の表面粗さが、中間側第１弾性片４１Ｂの表面において第１接点部４２の周辺領域（雄端子１０と接触する領域）における表面粗さよりも大きくされている。 On the upper surface of the end-side first elastic piece 41A (the surface on the side facing the male tab 11), the peripheral region of the first contact portion 42 is roughened by a roughening process. On the other hand, the surface of the intermediate side first elastic piece 41B is a smooth surface that is not subjected to the roughening treatment. As a result, the end-side first elastic piece 41A has a surface roughness of the peripheral area (area in contact with the male terminal 10) of the first contact portion 42 on the surface thereof, on the surface of the intermediate-side first elastic piece 41B. It is larger than the surface roughness in the peripheral region of the one contact portion 42 (region in contact with the male terminal 10).
　同様に、３本の第２弾性片４３のうち、両端に配される一対の第２弾性片４３は、端部側第２弾性片４３Ａとされ、これら一対の端部側第２弾性片４３Ａの間に配される第２弾性片４３は、中間側第２弾性片４３Ｂとされている。 Similarly, of the three second elastic pieces 43, the pair of second elastic pieces 43 arranged at both ends are end side second elastic pieces 43A, and the pair of end side second elastic pieces 43A. The second elastic piece 43 disposed between the two is an intermediate second elastic piece 43B.
　端部側第２弾性片４３Ａの上面（雄タブ１１と対向する側の面）において、第２接点部４４の周辺領域は、粗面化処理が施されることにより粗面化されている。一方、中間側第２弾性片４３Ｂの表面は、粗面化処理が施されていない平滑な表面となっている。このように、端部側第２弾性片４３Ａは、その表面において第２接点部４４の周辺領域（雄端子１０と接触する領域）の表面粗さが、中間側第２弾性片４３Ｂの表面において第２接点部４４の周辺領域（雄端子１０と接触する領域）における表面粗さよりも大きくされている。 On the upper surface of the end-side second elastic piece 43A (the surface facing the male tab 11), the peripheral area of the second contact portion 44 is roughened by a roughening process. On the other hand, the surface of the intermediate second elastic piece 43B is a smooth surface that has not been subjected to roughening treatment. As described above, the end-side second elastic piece 43A has a surface roughness of the peripheral area of the second contact portion 44 (area in contact with the male terminal 10) on the surface of the intermediate-side second elastic piece 43B. The surface roughness in the peripheral area of the second contact portion 44 (area in contact with the male terminal 10) is made larger.
　これにより、端部側第１弾性片４１Ａおよび端部側第２弾性片４３Ａの雄タブ１１に対する摩擦力が、中間側第１弾性片４１Ｂおよび中間側第２弾性片４３Ｂの雄タブ１１に対する摩擦力よりも大きくなるように設計されている。 As a result, the frictional force of the end side first elastic piece 41A and the end side second elastic piece 43A on the male tab 11 becomes the friction of the intermediate side first elastic piece 41B and the intermediate side second elastic piece 43B on the male tab 11. Designed to be greater than force.
　このような構成によれば、雄タブ１１は、幅方向の両端部において、雄タブ１１に対する摩擦力が大きくされた端部側第１弾性片４１Ａと端部側第２弾性片４３Ａとで保持されることとなり、幅方向の両端において強い保持力で保持されることとなる。これにより、両端子１０、４０が雄端子１０の幅方向に沿う方向に相対的に摺動し、微摺動摩耗が生じることを抑制でき、両端子１０、４０の電気的な接続信頼性を確保できる。 According to such a configuration, the male tab 11 is held by the end-side first elastic piece 41A and the end-side second elastic piece 43A in which the frictional force against the male tab 11 is increased at both ends in the width direction. As a result, both ends in the width direction are held with a strong holding force. Thereby, it can suppress that both terminals 10 and 40 slide relatively in the direction along the width direction of the male terminal 10, and a fine sliding wear arises, and the electrical connection reliability of both terminals 10 and 40 can be suppressed. It can be secured.
