Description

雌端子Female terminal
　本発明は、雄端子に接続される雌端子に関する。 The present invention relates to a female terminal connected to a male terminal.
　従来、雄端子に接続される雌端子として、特許文献１に記載のものが知られている。この雌端子は、雄端子が挿入される筒部を備える。筒部の内部には、筒部内に挿入された雄端子に弾性的に接触する弾性片が形成されている。この弾性片と、筒部の内壁面との間に雄端子が挟まれることにより、雄端子と雌端子とが電気的に接続されるようになっている。 Conventionally, the thing of patent document 1 is known as a female terminal connected to a male terminal. The female terminal includes a cylindrical portion into which the male terminal is inserted. An elastic piece that elastically contacts a male terminal inserted into the cylindrical portion is formed inside the cylindrical portion. A male terminal is sandwiched between the elastic piece and the inner wall surface of the cylindrical portion, whereby the male terminal and the female terminal are electrically connected.

　上記の構成に係る雌端子においては、雄端子及び雌端子の少なくとも一方が雄端子の筒部内への挿入方向を軸として相対的に捻回すると、弾性片と雄端子との間に隙間が発生して、雄端子に対する適正な接触圧が得られなくなるおそれがある。すると、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 female terminal according to the above configuration, when at least one of the male terminal and the female terminal is relatively twisted about the insertion direction of the male terminal into the cylindrical portion, a gap is generated between the elastic piece and the male terminal. As a result, there is a possibility that an appropriate contact pressure with respect to the male terminal cannot be obtained. Then, 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、雄端子及び雌端子の少なくとも一方が捻回した場合でも、雄端子との電気的な接続信頼性を得ることの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-described circumstances, and can provide electrical connection reliability with a male terminal even when at least one of a male terminal and a female terminal is twisted. The purpose is to provide a terminal.
　本発明は、雌端子であって、雄端子が挿入される筒部と、前記筒部の底壁から前記筒部の内方に突出すると共に、前記筒部内への前記雄端子の挿入方向と交差する方向に並ぶ複数の第１弾性片と、前記筒部のうち前記底壁と対向する天井壁から前記筒部の内方に突出すると共に、前記筒部内への前記雄端子の挿入方向と交差する方向に並ぶ複数の第２弾性片と、前記複数の第１弾性片にエンボス状に突出してそれぞれ形成された複数の第１接点部と、前記複数の第２弾性片のうち前記複数の第１接点部のそれぞれに対応する位置に配されて、前記複数の第２弾性片にエンボス状に突出してそれぞれ形成され、前記複数の第１接点部のそれぞれとの間に前記雄端子を挟む複数の第２接点部と、を備える。 The present invention is a female terminal, a cylindrical portion into which a male terminal is inserted, and an inward direction of the male terminal into the cylindrical portion while projecting inward from the bottom wall of the cylindrical portion. A plurality of first elastic pieces arranged in an intersecting direction, and protruding from the ceiling wall of the cylindrical portion facing the bottom wall inward of the cylindrical portion, and the insertion direction of the male terminal into the cylindrical portion; A plurality of second elastic pieces arranged in an intersecting direction, a plurality of first contact portions formed in an embossed manner on the plurality of first elastic pieces, and the plurality of second elastic pieces among the plurality of second elastic pieces. It is arranged at a position corresponding to each of the first contact portions, is formed to protrude in the shape of an emboss on the plurality of second elastic pieces, and the male terminal is sandwiched between each of the plurality of first contact portions. A plurality of second contact portions.
　本発明によれば、筒部内に挿入された雄端子は、第１弾性片の第１接点部と第２弾性片の第２接点部との間に進入する。第１弾性片の第１接点部が雄端子を押圧することにより、雄端子は第２接点部に適正な接触圧で押圧され、第２弾性片の第２接点部が雄端子を押圧することにより、雄端子は第１接点部に適正な接触圧で押圧される。これにより、雄端子と雌端子とが電気的に接続される。 According to the present invention, the male terminal inserted into the cylindrical portion enters between the first contact portion of the first elastic piece and the second contact portion of the second elastic piece. When the first contact portion of the first elastic piece presses the male terminal, the male terminal is pressed to the second contact portion with an appropriate contact pressure, and the second contact portion of the second elastic piece presses the male terminal. Thus, the male terminal is pressed against the first contact portion with an appropriate contact pressure. Thereby, the male terminal and the female terminal are electrically connected.
　雄端子が、雄端子の筒部内への挿入方向を軸として捻回すると、この挿入方向に交差する方向に並ぶ複数の第１弾性片は、雄端子の捻回動作に追従して弾性変形する。これにより、雄端子に対して各第１弾性片が適正な接触圧を加えることができるので、雄端子は第２接点部に適正な接触圧で押圧される。この結果、雄端子が、雄端子の筒部内への挿入方向を軸として捻回した場合でも、雄端子と雌端子との間の電気的な接続信頼性を得ることができる。 When the male terminal is twisted about the insertion direction of the male terminal into the cylindrical portion as an axis, the plurality of first elastic pieces arranged in a direction intersecting the insertion direction are elastically deformed following the twisting operation of the male terminal. . Thereby, since each 1st elastic piece can apply an appropriate contact pressure with respect to a male terminal, a male terminal is pressed by an appropriate contact pressure to a 2nd contact part. As a result, the electrical connection reliability between the male terminal and the female terminal can be obtained even when the male terminal is twisted about the insertion direction of the male terminal into the cylindrical portion.
　同様に、雄端子が、雄端子の筒部内への挿入方向を軸として捻回すると、この挿入方向に交差する方向に並ぶ複数の第２弾性片は、雄端子の捻回動作に追従して弾性変形する。これにより、雄端子に対して各第２弾性片が適正な接触圧を加えることができるので、雄端子は第１接点部に適正な接触圧で押圧される。この結果、雄端子が、雄端子の筒部内への挿入方向を軸として捻回した場合でも、雄端子と雌端子との間の電気的な接続信頼性を得ることができる。 Similarly, when the male terminal is twisted about the insertion direction of the male terminal into the cylindrical portion, the plurality of second elastic pieces arranged in the direction intersecting the insertion direction follows the twisting operation of the male terminal. Elastically deforms. Thereby, since each 2nd elastic piece can apply an appropriate contact pressure with respect to a male terminal, a male terminal is pressed by the 1st contact part with an appropriate contact pressure. As a result, the electrical connection reliability between the male terminal and the female terminal can be obtained even when the male terminal is twisted about the insertion direction of the male terminal into the cylindrical portion.
　更に、雄端子は、第１弾性片と第２弾性片との間に挟まれるので、雄端子には、第１弾性片と第２弾性片の双方から、適正な接触圧が加えられる。これにより、雄端子と雌端子との電気的な接続信頼性を確実なものとすることができる。 Furthermore, since the male terminal is sandwiched between the first elastic piece and the second elastic piece, an appropriate contact pressure is applied to the male terminal from both the first elastic piece and the second elastic piece. Thereby, the electrical connection reliability of a male terminal and a female terminal can be ensured.
　これらに加えて、第１接点部及び第２接点部はいずれもエンボス状に突出して形成されているため、雄端子との接触面が球面となり、雄端子が捻回しても雄端子との接触状態が捻回前と変わることがない。すなわち、捻回前に面接触状態にあるときは捻回後においても面接触状態に保たれ、捻回前に線接触状態にあるときは捻回後においても線接触状態に保たれ、捻回前に点接触状態にあるときは捻回後においても点接触状態に保たれるようになっている。言い換えると、捻回前に面接触状態にあったものが捻回後に線接触状態もしくは点接触状態に変化したり、捻回前に線接触状態にあったものが捻回後に点接触状態に変化したりすることがないようにされている。これにより、雄端子の捻回動作に対して第１弾性片及び第２弾性片がさらに追従しやすくなる。 In addition to these, since both the first contact portion and the second contact portion are formed to protrude in an embossed shape, the contact surface with the male terminal becomes a spherical surface, and even if the male terminal is twisted, it contacts with the male terminal. The state does not change from before twisting. That is, when in a surface contact state before twisting, it is kept in a surface contact state even after twisting, and when in a line contact state before twisting, it is kept in a line contact state even after twisting. When in a point contact state before, the point contact state is maintained even after twisting. In other words, what was in surface contact before twisting changes to line contact or point contact after twisting, or what was in line contact before twisting changes to point contact after twisting There is nothing to do. Thereby, it becomes easier for the first elastic piece and the second elastic piece to follow the twisting operation of the male terminal.
　本発明の実施態様としては以下の態様が好ましい。
　前記複数の第１弾性片は、前記筒部における前記挿入方向と交差する方向のほぼ全域に亘って等しい間隔を空けて配されていることが好ましい。 As embodiments of the present invention, the following embodiments are preferable.
It is preferable that the plurality of first elastic pieces are arranged at equal intervals over substantially the entire region in the direction intersecting the insertion direction in the cylindrical portion.
　上記の態様によれば、複数の第１弾性片は、雄端子の全体に等しい間隔を空けて接触する。これにより、各第１弾性片は雄端子の捻回動作に容易に追従できるので、雄端子と雌端子の電気的な接続信頼性を向上させることができる。 According to the above aspect, the plurality of first elastic pieces are in contact with the entire male terminal at equal intervals. Thereby, since each 1st elastic piece can follow the twisting operation | movement of a male terminal easily, the electrical connection reliability of a male terminal and a female terminal can be improved.

It is preferable.
　複数の第１弾性片が形成される構成によると、各第１弾性片の剛性が低下することが懸念される。この第１弾性片に異物が衝突すると、第１弾性片が変形するおそれがある。本態様によれば、底壁の前端縁には第１基端部が位置しているので、異物が直接に第１弾性片に衝突することを抑制できる。また、第１基端部は第１弾性片に比べて剛性が大きいので、異物が衝突した場合でも変形しにくくなっている。これにより、異物の衝突により、第１弾性片の筒部内における位置がずれることが抑制されるので、雄端子に対して適正な接触圧を加えることができる。 According to the configuration in which a plurality of first elastic pieces are formed, there is a concern that the rigidity of each first elastic piece is lowered. When a foreign object collides with the first elastic piece, the first elastic piece may be deformed. According to this aspect, since the 1st base end part is located in the front-end edge of a bottom wall, it can suppress that a foreign material collides with a 1st elastic piece directly. Further, since the first base end portion has higher rigidity than the first elastic piece, it is difficult to deform even when a foreign object collides. Thereby, since the position in the cylinder part of the 1st elastic piece by the collision of a foreign material is suppressed, appropriate contact pressure can be applied to a male terminal.
　前記複数の第２弾性片は、前記筒部における前記挿入方向と交差する方向のほぼ全域に亘って等しい間隔を空けて配されていることが好ましい。 It is preferable that the plurality of second elastic pieces are arranged at equal intervals over substantially the entire region in the direction intersecting the insertion direction in the cylindrical portion.

Thereby, since each 2nd elastic piece can track easily the twisting operation | movement of a male terminal, the electrical connection reliability of a male terminal and a female terminal can be improved.
　前記天井壁の前端縁から前記筒部の内方に折り返された形状をなす第２基端部を有し、前記複数の第２弾性片は前記第２基端部から後方に延びて形成されていることが好ましい。 A second base end portion having a shape folded inward from the front end edge of the ceiling wall; and the plurality of second elastic pieces are formed to extend rearward from the second base end portion. It is preferable.
　複数の第２弾性片が形成される構成によると、各第２弾性片の剛性が低下することが懸念される。この第２弾性片に異物が衝突すると、第２弾性片が変形するおそれがある。本態様によれば、底壁の前端縁には第２基端部が位置しているので、異物が直接に第２弾性片に衝突することを抑制できる。また、第２基端部は第２弾性片に比べて剛性が大きいので、異物が衝突した場合でも変形しにくくなっている。これにより、異物の衝突により、第２弾性片の筒部内における位置がずれることが抑制されるので、雄端子に対して適正な接触圧を加えることができる。 According to the configuration in which a plurality of second elastic pieces are formed, there is a concern that the rigidity of each second elastic piece is lowered. When a foreign object collides with the second elastic piece, the second elastic piece may be deformed. According to this aspect, since the 2nd base end part is located in the front-end edge of a bottom wall, it can suppress that a foreign material collides with a 2nd elastic piece directly. Further, since the second base end portion has higher rigidity than the second elastic piece, it is difficult to deform even when a foreign object collides. Thereby, since the position in the cylinder part of the 2nd elastic piece by the collision of a foreign material is suppressed, appropriate contact pressure can be applied to a male terminal.

The female terminal 10 has a cylindrical portion 14 into which the male tab 12 of the male terminal 11 is inserted. As shown in FIGS. 2 to 4, the tube portion 14 has a substantially rectangular tube shape that opens in the front-rear direction. The cylindrical portion 14 includes a bottom wall 15, a pair of side walls 16 that rise upward from both side edges of the bottom wall 15, and a ceiling wall 17 that faces the bottom wall 15.

A locking portion 18 protrudes from the side edge of the ceiling wall 17, and the locking portion 18 is inserted into a locking hole 19 formed in the other side wall 16. The side edge of the other side wall 16 is folded on the upper surface of the ceiling wall 17. Thereby, the cylinder part 14 is hold | maintained at the square cylinder shape.

As shown in FIG. 1, a core wire 22 exposed from the insulating coating 21 at the end of the electric wire 13 is connected to the wire barrel 20. The wire barrel 20 is crimped so as to be wound around the outer surface of the core wire 22.
（第１弾性片２３）
　底壁１５の前端縁には、第１基端部２４が突出して形成されている。第１基端部２４は、底壁１５の前端縁から筒部１４の内方に（後方に）折り返された形状をなしている。図４に示すように、第１基端部２４は筒部１４の前端縁から前方にやや突出している。 (First elastic piece 23)
A first base end portion 24 protrudes from the front end edge of the bottom wall 15. The first base end portion 24 has a shape that is folded back (backward) from the front end edge of the bottom wall 15 to the inside of the cylindrical portion 14. As shown in FIG. 4, the first base end portion 24 slightly protrudes forward from the front end edge of the cylindrical portion 14.
　図５に示すように、折り返された第１基端部２４の後端縁には、雄端子１１の挿入方向と交差する方向に間隔を空けて並ぶ複数（本実施形態では３つ）の第１弾性片２３が筒部１４の内方に（後方に）突出して形成されている。第１弾性片２３は側方から見て第１基端部２４から片持ち状をなして直線状に延出されている。この第１弾性片２３の延出端部に第１接点部２５が形成され、この第１接点部２５が雄端子１１と弾性的に接触する。各第１弾性片２３の、前後方向の長さ寸法は略同じに形成されている。また、各第１弾性片２３の、雄端子１１の挿入方向と直交する方向（以下「幅方向」という）についての幅寸法は、略同じに形成されている。また、隣り合う一対の第１弾性片２３の間隔は、いずれも略同じとされている。したがって、複数の第１弾性片２３は、筒部１４における幅方向のほぼ全域に亘って等しい間隔を空けて配されている。 As shown in FIG. 5, a plurality (three in this embodiment) of the first base end portion 24 folded back are arranged at intervals in the direction intersecting the insertion direction of the male terminal 11. One elastic piece 23 is formed to protrude inward (rearward) of the cylindrical portion 14. The first elastic piece 23 is cantilevered from the first base end portion 24 as viewed from the side and extends linearly. A first contact portion 25 is formed at the extending end of the first elastic piece 23, and the first contact portion 25 is in elastic contact with the male terminal 11. The first elastic pieces 23 are formed to have substantially the same length in the front-rear direction. Further, the width dimension of each first elastic piece 23 in the direction orthogonal to the insertion direction of the male terminal 11 (hereinafter referred to as “width direction”) is formed substantially the same. Further, the interval between the pair of adjacent first elastic pieces 23 is substantially the same. Accordingly, the plurality of first elastic pieces 23 are arranged at equal intervals over substantially the entire width direction of the cylindrical portion 14.
　第１弾性片２３は、少なくとも、雄端子１１の挿入方向と交差する方向について両端部寄りの位置に一対形成されており、これら一対の第１弾性片２３については雄端子１１の両側縁寄りの部分と接触するようになっている。一方、雄端子１１の挿入方向と交差する方向について中央に位置する第１弾性片２３は、雄端子１１の中央部分と接触するようになっている。したがって、複数の第１弾性片２３は、雄端子１１のほぼ全幅に亘って均等に配されている。 A pair of first elastic pieces 23 are formed at positions near both ends in a direction intersecting at least the insertion direction of the male terminal 11, and the pair of first elastic pieces 23 are located near both side edges of the male terminal 11. It comes in contact with the part. On the other hand, the first elastic piece 23 located in the center in the direction intersecting with the insertion direction of the male terminal 11 comes into contact with the central portion of the male terminal 11.

As shown in FIG. 6, one first contact portion 25 is formed on each first elastic piece 23, and the contact surface with the male terminal 11 is a spherical surface. As shown in FIG. 5, the first contact portion 25 is formed over substantially the entire width of the first elastic piece 23, and the front-rear dimension is slightly larger than the width dimension. As a result, the contact surface with the male terminal 11 is concentrated on one point and the first contact portion 25 is avoided from being worn. The first contact portion 25 is not easily worn by the twisting operation of the terminal 11.
（第２弾性片２６）
　天井壁１７の前端縁には、第２基端部２７が突出して形成されている。第２基端部２７は、天井壁１７の前端縁から筒部１４の内方に（後方に）折り返された形状をなしている。図４に示すように、第２基端部２７は筒部１４の前端縁から前方にやや突出している。 (Second elastic piece 26)
A second base end portion 27 protrudes from the front end edge of the ceiling wall 17. The second base end portion 27 has a shape that is folded back (backward) from the front end edge of the ceiling wall 17 to the inside of the tubular portion 14. As shown in FIG. 4, the second base end portion 27 slightly protrudes forward from the front end edge of the cylindrical portion 14.
　図６に示すように、折り返された第２基端部２７の後端縁には、雄端子１１の挿入方向と交差する方向に間隔を空けて並ぶ複数（本実施形態では３つ）の第２弾性片２６が筒部１４の内方に（後方に）突出して形成されている。第２弾性片２６は側方から見て第２基端部２７から片持ち状をなして直線状に延出されている。この第２弾性片２６の延出端部に第２接点部２８が形成され、この第２接点部２８が雄端子１１と弾性的に接触する。各第２弾性片２６の、前後方向の長さ寸法は略同じに形成されている。また、各第２弾性片２６の、雄端子１１の挿入方向と直交する方向（以下「幅方向」という）についての幅寸法は、略同じに形成されている。また、隣り合う一対の第２弾性片２６の間隔は、いずれも略同じとされている。したがって、複数の第２弾性片２６は、筒部１４における幅方向のほぼ全域に亘って等しい間隔を空けて配されている。 As shown in FIG. 6, a plurality (three in this embodiment) of the second base end portion 27 that are folded back are arranged at intervals in the direction intersecting the insertion direction of the male terminal 11. Two elastic pieces 26 are formed so as to protrude inward (rearward) of the cylindrical portion 14. The second elastic piece 26 is cantilevered from the second base end portion 27 as viewed from the side, and extends linearly. A second contact portion 28 is formed at the extended end portion of the second elastic piece 26, and the second contact portion 28 elastically contacts the male terminal 11. Each second elastic piece 26 is formed to have substantially the same length in the front-rear direction. Further, the width dimension of each second elastic piece 26 in the direction orthogonal to the insertion direction of the male terminal 11 (hereinafter referred to as “width direction”) is formed substantially the same. Further, the interval between the pair of adjacent second elastic pieces 26 is substantially the same. Therefore, the plurality of second elastic pieces 26 are arranged at equal intervals over substantially the entire width direction of the cylindrical portion 14.
　詳細には図示しないが、第２弾性片２６は、少なくとも、雄端子１１の挿入方向と交差する方向について両端部寄りの位置に一対形成されており、これら一対の第２弾性片２６については雄端子１１の両側縁寄りの部分と接触するようになっている。一方、雄端子１１の挿入方向と交差する方向について中央に位置する第２弾性片２６は、雄端子１１の中央部分と接触するようになっている。したがって、複数の第２弾性片２６は、雄端子１１のほぼ全幅に亘って均等に配されている。 Although not shown in detail, a pair of the second elastic pieces 26 are formed at positions near both ends in at least the direction intersecting the insertion direction of the male terminal 11, and the pair of second elastic pieces 26 are male. The terminal 11 is in contact with portions near both side edges. On the other hand, the second elastic piece 26 located in the center in the direction intersecting the insertion direction of the male terminal 11 comes into contact with the central portion of the male terminal 11. Therefore, the plurality of second elastic pieces 26 are evenly arranged over substantially the entire width of the male terminal 11.
　第２接点部２８はエンボス状をなし、雄端子１１との接触面側に叩き出されて形成されている。この第２接点部２８は、図６に示すように、各第２弾性片２６に一つずつ形成されており、雄端子１１との接触面が球面とされている。また、第２接点部２８は、図１及び図７に示すように、第２弾性片２６のほぼ全幅に亘って形成され、幅寸法よりも前後寸法がわずかに大きく形成されている。これにより、雄端子１１との接触面が一点に集中して第２接点部２８が摩耗することを回避し、雄端子１１の捻回動作に対して広範囲で雄端子１１と接触する結果、雄端子１１の捻回動作によって第２接点部２８が摩耗しにくくなっている。 The second contact portion 28 has an embossed shape and is formed by being knocked out toward the contact surface with the male terminal 11. As shown in FIG. 6, one second contact portion 28 is formed on each second elastic piece 26, and the contact surface with the male terminal 11 is a spherical surface. As shown in FIGS. 1 and 7, the second contact portion 28 is formed over substantially the entire width of the second elastic piece 26, and the front-rear dimension is slightly larger than the width dimension. As a result, the contact surface with the male terminal 11 is concentrated on one point and the second contact portion 28 is avoided from being worn, and the male terminal 11 contacts the male terminal 11 in a wide range with respect to the twisting operation of the male terminal 11. The second contact portion 28 is hardly worn by the twisting operation of the terminal 11.
　図１、図６及び図７に示すように、第１基端部２４及び第１弾性片２３と、第２基端部２７及び第２弾性片２６とは、上下対称に形成されている。これにより、第１弾性片２３の第１接点部２５と、第２弾性片２６の第２接点部２８とは、それぞれ対向して配されている（図７参照）。 As shown in FIGS. 1, 6 and 7, the first base end portion 24 and the first elastic piece 23, and the second base end portion 27 and the second elastic piece 26 are formed vertically symmetrically. Thereby, the 1st contact part 25 of the 1st elastic piece 23 and the 2nd contact part 28 of the 2nd elastic piece 26 are each arrange | positioned facing each other (refer FIG. 7).
（本実施形態の作用、効果）
　続いて、本実施形態の作用、効果について説明する。図６に示す状態から雄端子１１が筒部１４内に挿入されると、雄端子１１は、第１弾性片２３と第２弾性片２６との間に進入する。すると、雄端子１１に押圧されることにより、第１弾性片２３は下方に弾性変形し、第２弾性片２６は上方に弾性変形する。更に雄端子１１が筒部１４の後方に進入すると、図８に示すように、雄端子１１は、第１弾性片２３の第１接点部２５と、第２弾性片２６の第２接点部２８との間に進入する。第１弾性片２３の弾発力により雄端子１１が押圧されることにより、雄端子１１は第２接点部２８に適正な接触圧で押圧される。一方、第２弾性片２６の弾発力により雄端子１１が押圧されることにより、雄端子１１は第１接点部２５に適正な接触圧で押圧される。これにより、雄端子１１と雌端子１０とが電気的に接続される。 (Operation and effect of this embodiment)
Then, the effect | action and effect of this embodiment are demonstrated. When the male terminal 11 is inserted into the cylindrical portion 14 from the state shown in FIG. 6, the male terminal 11 enters between the first elastic piece 23 and the second elastic piece 26. Then, when pressed by the male terminal 11, the first elastic piece 23 is elastically deformed downward, and the second elastic piece 26 is elastically deformed upward. When the male terminal 11 further enters the rear of the cylindrical portion 14, the male terminal 11 is connected to the first contact portion 25 of the first elastic piece 23 and the second contact portion 28 of the second elastic piece 26 as shown in FIG. 8. Enter between. When the male terminal 11 is pressed by the elastic force of the first elastic piece 23, the male terminal 11 is pressed against the second contact portion 28 with an appropriate contact pressure. On the other hand, when the male terminal 11 is pressed by the elastic force of the second elastic piece 26, the male terminal 11 is pressed against the first contact portion 25 with an appropriate contact pressure. Thereby, the male terminal 11 and the female terminal 10 are electrically connected.
　図９には、雄端子１１が、筒部１４内への雄端子１１の挿入方向を軸として捻回した状態を示す。図８に示す正規の挿入状態から雄端子１１を反時計回り方向に捻回させていくと、雄端子１１と各接点部２５、２８の接点位置は、各接点部２５、２８の接触面に沿って反時計回り方向にわずかに移動しながら、図９に示す姿勢に至る。このため、各接点部２５、２８に対して雄端子１１が一点に集中して接触することを回避できる。 FIG. 9 shows a state in which the male terminal 11 is twisted around the insertion direction of the male terminal 11 into the cylindrical portion 14 as an axis. When the male terminal 11 is twisted counterclockwise from the normal insertion state shown in FIG. 8, the contact position between the male terminal 11 and each contact portion 25, 28 is on the contact surface of each contact portion 25, 28. 9 and moves slightly in the counterclockwise direction to reach the posture shown in FIG. For this reason, it can avoid that the male terminal 11 concentrates on one point with respect to each contact part 25 and 28, and contacts.
　また、雄端子１１は、捻回動作の前後において各接点部２５、２８に対して同じように点接触状態あるいは線接触状態を保持しているため、雄端子１１と各接点部２５、２８の接触状態が急激に変化することはなく、いずれの接触箇所においても十分な接圧が確保されている。すなわち、捻回前に雄端子１１が各接点部２５、２８に対して線接触している場合には、捻回後においても雄端子１１が各接点部２５、２８に対して線接触しており、捻回目に雄端子１１が各接点部２５、２８に対して点接触している場合には、捻回後においても各接点部２５、２８に対して点接触していることになる。 Further, since the male terminal 11 maintains the point contact state or the line contact state with respect to the contact portions 25 and 28 before and after the twisting operation, the male terminal 11 and the contact portions 25 and 28 The contact state does not change abruptly, and a sufficient contact pressure is ensured at any contact location. That is, when the male terminal 11 is in line contact with the contact portions 25 and 28 before twisting, the male terminal 11 is in line contact with the contact portions 25 and 28 even after twisting. In addition, when the male terminal 11 is in point contact with the contact portions 25 and 28 at the twisting time, it is point contact with the contact portions 25 and 28 even after twisting.
　また、複数の第１弾性片２３は、雄端子１１の挿入方向に交差する方向に等しい間隔を空けて並んで形成されているので、各第１弾性片２３は、雄端子１１の捻回動作に追従して弾性変形する。これにより、雄端子１１に対して各第１弾性片２３が適正な接触圧を加えることができるので、雄端子１１は第２接点部２８に適正な接触圧で押圧される。 Further, since the plurality of first elastic pieces 23 are formed side by side at equal intervals in the direction intersecting the insertion direction of the male terminal 11, each first elastic piece 23 is twisted by the male terminal 11. It will elastically deform following. Thereby, since each 1st elastic piece 23 can apply an appropriate contact pressure with respect to the male terminal 11, the male terminal 11 is pressed by the 2nd contact part 28 with an appropriate contact pressure.
　同様に、雄端子１１が、雄端子１１の挿入方向に交差する方向に等しい間隔を空けて並ぶ複数の第２弾性片２６も、雄端子１１の捻回動作に追従して弾性変形する。これにより、雄端子１１に対して各第２弾性片２６が適正な接触圧を加えることができるので、雄端子１１は第１接点部２５に適正な接触圧で押圧される。 Similarly, the plurality of second elastic pieces 26 in which the male terminals 11 are arranged at equal intervals in the direction intersecting the insertion direction of the male terminals 11 are also elastically deformed following the twisting operation of the male terminals 11. Thereby, since each 2nd elastic piece 26 can apply an appropriate contact pressure with respect to the male terminal 11, the male terminal 11 is pressed by the 1st contact part 25 with an appropriate contact pressure.
　以上のように本実施形態によると、筒部１４内に挿入された雄端子１１は、第１弾性片２３の第１接点部２５と第２弾性片２６の第２接点部２８との間に進入する。第１弾性片２３の第１接点部２５が雄端子１１を押圧することにより、雄端子１１は第２接点部２８に適正な接触圧で押圧され、第２弾性片２６の第２接点部２８が雄端子１１を押圧することにより、雄端子１１は第１接点部２５に適正な接触圧で押圧される。これにより、雄端子１１と雌端子１０とが電気的に接続される。 As described above, according to this embodiment, the male terminal 11 inserted into the cylindrical portion 14 is between the first contact portion 25 of the first elastic piece 23 and the second contact portion 28 of the second elastic piece 26. enter in. When the first contact portion 25 of the first elastic piece 23 presses the male terminal 11, the male terminal 11 is pressed against the second contact portion 28 with an appropriate contact pressure, and the second contact portion 28 of the second elastic piece 26. When the male terminal 11 is pressed, the male terminal 11 is pressed against the first contact portion 25 with an appropriate contact pressure. Thereby, the male terminal 11 and the female terminal 10 are electrically connected.
　雄端子１１が、雄端子１１の筒部１４内への挿入方向を軸として捻回すると、この挿入方向に交差する方向に並ぶ複数の第１弾性片２３は、雄端子１１の捻回動作に追従して弾性変形する。これにより、雄端子１１に対して各第１弾性片２３が適正な接触圧を加えることができるので、雄端子１１は第２接点部２８に適正な接触圧で押圧される。この結果、雄端子１１が、雄端子１１の筒部１４内への挿入方向を軸として捻回した場合でも、雄端子１１と雌端子１０との間の電気的な接続信頼性を得ることができる。 When the male terminal 11 is twisted with the insertion direction of the male terminal 11 into the cylindrical portion 14 as an axis, the plurality of first elastic pieces 23 arranged in a direction crossing the insertion direction are used for the twisting operation of the male terminal 11. Follow and elastically deform. Thereby, since each 1st elastic piece 23 can apply an appropriate contact pressure with respect to the male terminal 11, the male terminal 11 is pressed by the 2nd contact part 28 with an appropriate contact pressure. As a result, even when the male terminal 11 is twisted with the insertion direction of the male terminal 11 into the cylindrical portion 14 as an axis, electrical connection reliability between the male terminal 11 and the female terminal 10 can be obtained. it can.
　同様に、雄端子１１が、雄端子１１の筒部１４内への挿入方向を軸として捻回すると、この挿入方向に交差する方向に並ぶ複数の第２弾性片２６は、雄端子１１の捻回動作に追従して弾性変形する。これにより、雄端子１１に対して各第２弾性片２６が適正な接触圧を加えることができるので、雄端子１１は第１接点部２５に適正な接触圧で押圧される。この結果、雄端子１１が、雄端子１１の筒部１４内への挿入方向を軸として捻回した場合でも、雄端子１１と雌端子１０との間の電気的な接続信頼性を得ることができる。 Similarly, when the male terminal 11 is twisted with the insertion direction of the male terminal 11 into the cylindrical portion 14 as an axis, the plurality of second elastic pieces 26 arranged in a direction crossing the insertion direction are twisted of the male terminal 11. Elastically deforms following the turning motion. Thereby, since each 2nd elastic piece 26 can apply an appropriate contact pressure with respect to the male terminal 11, the male terminal 11 is pressed by the 1st contact part 25 with an appropriate contact pressure. As a result, even when the male terminal 11 is twisted with the insertion direction of the male terminal 11 into the cylindrical portion 14 as an axis, electrical connection reliability between the male terminal 11 and the female terminal 10 can be obtained. it can.
　更に、雄端子１１は、第１弾性片２３と第２弾性片２６との間に挟まれるので、雄端子１１には、第１弾性片２３と第２弾性片２６の双方から、適正な接触圧が加えられる。これにより、雄端子１１と雌端子１０との電気的な接続信頼性を確実なものとすることができる。 Further, since the male terminal 11 is sandwiched between the first elastic piece 23 and the second elastic piece 26, the male terminal 11 can be properly contacted from both the first elastic piece 23 and the second elastic piece 26. Pressure is applied. Thereby, the electrical connection reliability of the male terminal 11 and the female terminal 10 can be ensured.
　これらに加えて、第１接点部２５及び第２接点部２８はいずれもエンボス状に突出して形成されているため、雄端子１１との接触面が球面となり、雄端子１１が捻回しても雄端子１１との接触状態が捻回前と変わることがない。これにより、雄端子１１の捻回動作に対して第１弾性片２３及び第２弾性片２６がさらに追従しやすくなる。 In addition to these, since both the first contact portion 25 and the second contact portion 28 are formed to protrude in an embossed shape, the contact surface with the male terminal 11 becomes a spherical surface, and even if the male terminal 11 is twisted, the male contact is made. The contact state with the terminal 11 does not change from that before twisting. Thereby, it becomes easier for the first elastic piece 23 and the second elastic piece 26 to follow the twisting operation of the male terminal 11.
　複数の第１弾性片２３は、筒部１４における前記挿入方向と交差する方向のほぼ全域に亘って等しい間隔を空けて配されていることが好ましい。この態様によれば、複数の第１弾性片は、雄端子１１の全体に等しい間隔を空けて接触する。これにより、各第１弾性片２３は雄端子１１の捻回動作に容易に追従できるので、雄端子１１と雌端子１０の電気的な接続信頼性を向上させることができる。 It is preferable that the plurality of first elastic pieces 23 are arranged at equal intervals over substantially the entire region in the direction intersecting the insertion direction in the cylindrical portion 14. According to this aspect, the plurality of first elastic pieces are in contact with the entire male terminal 11 at an equal interval. Accordingly, each first elastic piece 23 can easily follow the twisting operation of the male terminal 11, so that the electrical connection reliability between the male terminal 11 and the female terminal 10 can be improved.
　底壁１５の前端縁から筒部１４の内方に折り返された形状をなす第１基端部２４を有し、複数の第１弾性片２３は第１基端部２４から後方に延びて形成されていることが好ましい。複数の第１弾性片２３が形成される構成によると、各第１弾性片２３の剛性が低下することが懸念される。この第１弾性片２３に異物が衝突すると、第１弾性片２３が変形するおそれがある。本態様によれば、底壁１５の前端縁には第１基端部２４が位置しているので、異物が直接に第１弾性片２３に衝突することを抑制できる。また、第１基端部２４は第１弾性片２３に比べて剛性が大きいので、異物が衝突した場合でも変形しにくくなっている。これにより、異物の衝突により、第１弾性片２３の筒部１４内における位置がずれることが抑制されるので、雄端子１１に対して適正な接触圧を加えることができる。 The first base end portion 24 has a shape folded back from the front end edge of the bottom wall 15 to the inside of the cylindrical portion 14, and the plurality of first elastic pieces 23 are formed to extend rearward from the first base end portion 24. It is preferable that According to the configuration in which the plurality of first elastic pieces 23 are formed, there is a concern that the rigidity of each first elastic piece 23 is lowered. When a foreign object collides with the first elastic piece 23, the first elastic piece 23 may be deformed. According to this aspect, since the 1st base end part 24 is located in the front-end edge of the bottom wall 15, it can suppress that a foreign material collides with the 1st elastic piece 23 directly. Moreover, since the first base end portion 24 has higher rigidity than the first elastic piece 23, it is difficult to deform even when a foreign object collides. Thereby, since the position in the cylinder part 14 of the 1st elastic piece 23 is suppressed by the collision of a foreign material, an appropriate contact pressure can be applied to the male terminal 11.
　複数の第２弾性片２６は、筒部１４における挿入方向と交差する方向のほぼ全域に亘って等しい間隔を空けて配されていることが好ましい。この態様によれば、複数の第２弾性片２６は、雄端子１１の全体に等しい間隔を空けて接触する。これにより、各第２弾性片２６は雄端子１１の捻回動作に容易に追従できるので、雄端子１１と雌端子１０の電気的な接続信頼性を向上させることができる。 It is preferable that the plurality of second elastic pieces 26 are arranged at equal intervals over almost the entire region in the direction intersecting the insertion direction in the cylindrical portion 14. According to this aspect, the plurality of second elastic pieces 26 are in contact with the entire male terminal 11 at an equal interval. Thereby, each second elastic piece 26 can easily follow the twisting operation of the male terminal 11, so that the electrical connection reliability between the male terminal 11 and the female terminal 10 can be improved.
　天井壁１７の前端縁から筒部１４の内方に折り返された形状をなす第２基端部２７を有し、複数の第２弾性片２６は第２基端部２７から後方に延びて形成されていることが好ましい。複数の第２弾性片２６が形成される構成によると、各第２弾性片２６の剛性が低下することが懸念される。この第２弾性片２６に異物が衝突すると、第２弾性片２６が変形するおそれがある。本態様によれば、底壁１５の前端縁には第２基端部２７が位置しているので、異物が直接に第２弾性片２６に衝突することを抑制できる。また、第２基端部２７は第２弾性片２６に比べて剛性が大きいので、異物が衝突した場合でも変形しにくくなっている。これにより、異物の衝突により、第２弾性片２６の筒部１４内における位置がずれることが抑制されるので、雄端子１１に対して適正な接触圧を加えることができる。 A second base end portion 27 having a shape folded from the front end edge of the ceiling wall 17 to the inside of the cylindrical portion 14 is formed, and the plurality of second elastic pieces 26 are formed to extend rearward from the second base end portion 27. It is preferable that According to the configuration in which the plurality of second elastic pieces 26 are formed, there is a concern that the rigidity of each second elastic piece 26 is lowered. When a foreign object collides with the second elastic piece 26, the second elastic piece 26 may be deformed. According to this aspect, since the second base end portion 27 is located at the front end edge of the bottom wall 15, it is possible to suppress foreign matter from directly colliding with the second elastic piece 26. Further, since the second base end portion 27 has higher rigidity than the second elastic piece 26, it is difficult to deform even when a foreign object collides. Thereby, since the position in the cylinder part 14 of the 2nd elastic piece 26 is suppressed by the collision of a foreign material, an appropriate contact pressure can be applied to the male terminal 11.
