Description

雌端子Female terminal
　本明細書によって開示される技術は、雌端子に関する。 The technology disclosed in this specification relates to a female terminal.
　従来、雄端子に接続される雌端子として、例えば特開２０１３－２４３０１６号公報（下記特許文献１）に記載の雌端子が知られている。この雌端子は、雄端子の雄タブが挿入される筒部を有している。この筒部は、前後方向に開口する略角筒部をなし、底壁と、底壁の両側縁から上方に立ち上がる一対の側壁と、底壁に対向する天井壁とを備えて構成されている。底壁の前端縁には、第１基端部が前方に突出して形成されている。第１基端部は、底壁の前端縁から筒部の内方に折り返された形状をなしている。第１基端部の後端縁には、雄端子の挿入方向と交差する方向に間隔を空けて並ぶ複数の第１弾性片が筒部の内方に突出して形成されている。 Conventionally, as a female terminal connected to a male terminal, for example, a female terminal described in Japanese Patent Application Laid-Open No. 2013-243016 (Patent Document 1 below) is known. This female terminal has a cylindrical portion into which a male tab of a male terminal is inserted. The cylindrical portion is a substantially square cylindrical portion that opens in the front-rear direction, and includes a bottom wall, a pair of side walls that rise upward from both side edges of the bottom wall, and a ceiling wall that faces the bottom wall. . A first base end portion is formed on the front end edge of the bottom wall so as to protrude forward. The first base end portion has a shape that is folded back from the front end edge of the bottom wall to the inside of the cylindrical portion. A plurality of first elastic pieces arranged at intervals in the direction intersecting the insertion direction of the male terminal are formed on the rear end edge of the first base end portion so as to protrude inward of the cylindrical portion.
　この雌端子では、第１基端部を筒部の前端開口縁から前方に突出させて形成しており、この第１基端部の後端縁に連なるように第１弾性片が形成されている。このようにして第１基端部および第１弾性片を形成すると、筒部の前端開口縁から後方に向けて底壁の一部を切り欠く必要がないため、底壁の強度低下を防止することができる。なお、底壁の一部を切り欠くことで第１基端部および第１弾性片を形成するものとして、例えば特開平４－１４７６８０号公報（下記特許文献２）に記載のコネクタ端子が挙げられる。 In this female terminal, the first base end portion is formed to protrude forward from the front end opening edge of the tube portion, and the first elastic piece is formed so as to be continuous with the rear end edge of the first base end portion. Yes. When the first base end portion and the first elastic piece are formed in this way, it is not necessary to cut out a part of the bottom wall from the front end opening edge of the cylindrical portion to the rear, thereby preventing a decrease in strength of the bottom wall. be able to. In addition, as what forms a 1st base end part and a 1st elastic piece by notching a part of bottom wall, the connector terminal of Unexamined-Japanese-Patent No. 4-147680 (patent document 2 below) is mentioned, for example. .
　ところが、底壁の一部を切り欠くものでは、雌端子の母材となる金属材として板厚が大きいものを使用した場合に、金属材を打ち抜く際の最小幅寸法が大きくなるため、底壁における切り欠きの幅寸法が大きくなり、第１基端部および第１弾性片の幅寸法が小さくなってしまう。特に、大電流用の雌端子では、雄端子との接触面積を増加させて接触抵抗を少しでも下げる必要があるところ、第１基端部および第１弾性片の幅寸法を少しでも大きくすることが望ましく、第１基端部を筒部の前端開口縁から前方に突出させて形成することの技術的意義はこの点にあるといえる。 However, in the case where a part of the bottom wall is cut out, when a metal material having a large plate thickness is used as the base material of the female terminal, the minimum width dimension when punching the metal material becomes large. The width dimension of the notch becomes larger, and the width dimension of the first base end portion and the first elastic piece becomes smaller. In particular, in the case of a female terminal for large current, it is necessary to increase the contact area with the male terminal to lower the contact resistance as much as possible, but to increase the width dimension of the first base end and the first elastic piece as much as possible. It is desirable that the technical significance of forming the first base end portion to protrude forward from the front end opening edge of the tube portion is in this respect.

　このような構成によると、誤って雌端子を落とした際に、一対の保護壁によって第１基端部を保護することができる。 The female terminal disclosed in the present specification has a rectangular tube shape, a rectangular tube portion that opens forward at a front end opening edge, and a first base that protrudes forward from a part of the front end opening edge and is folded back. An end portion, a first elastic piece extending inward of the square tube portion from a rear end edge of the first base end portion, and a portion surrounding the first base end portion from both sides of the front end opening edge And a pair of protective walls provided so as to protrude forward.

　さて、図２に示すように、一対の側壁１６の前端縁１６０には、一対の保護壁２９が前方に突出して形成されている。これらの保護壁２９は、角筒部１４の前端開口縁１４０のうち第１基端部２４および第２基端部２７を左右両側から囲む位置に配されている。図１および図４に示すように、左右一対の保護壁２９の前端は、第１基端部２４および第２基端部２７の前端よりも前方に位置している。詳細には、各保護壁２９は、第１基端部２４および第２基端部２７のうち互いに対向する領域、すなわち雄端子１１の雄タブ１２が接触可能とされる領域を左右両側から囲むように形成されている。具体的には、各保護壁２９は、第１基端部２４の上半分と第２基端部２７の下半分を左右両側から囲んでいる。したがって、誤って雌端子１０を落下させた場合に、第１基端部２４および第２基端部２７が地面に衝突して損傷することを回避できる。 Now, as shown in FIG. 2, a pair of protective walls 29 project forward from the front end edges 160 of the pair of side walls 16. These protective walls 29 are arranged at positions that surround the first base end portion 24 and the second base end portion 27 from the left and right sides of the front end opening edge 140 of the square tube portion 14. As shown in FIGS. 1 and 4, the front ends of the pair of left and right protective walls 29 are positioned in front of the front ends of the first base end portion 24 and the second base end portion 27. Specifically, each protection wall 29 surrounds the first base end portion 24 and the second base end portion 27 opposite to each other, that is, the region where the male tab 12 of the male terminal 11 can be contacted from both the left and right sides. It is formed as follows. Specifically, each protective wall 29 surrounds the upper half of the first base end portion 24 and the lower half of the second base end portion 27 from the left and right sides. Therefore, when the female terminal 10 is accidentally dropped, the first base end portion 24 and the second base end portion 27 can be prevented from colliding with the ground and being damaged.
　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が角筒部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。さらに雄端子１１が角筒部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。 Subsequently, the operation and effect of this embodiment will be described. When the male terminal 11 is inserted into the rectangular tube 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 side of the rectangular tube 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 of the second elastic piece 26 as shown in FIG. 8. Enter 28. 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、角筒部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 rectangular tube 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、捻回前に雄端子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 the case where the male terminal 11 is in point contact with the contact portions 25 and 28 before twisting, the contact is in 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 arranged at equal intervals in the direction crossing the insertion direction of the male terminal 11 are also elastically deformed following the twisting operation of the male terminal 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の雌端子１０は、角筒状をなし、前端開口縁１４０において前方に開口する角筒部１４と、前端開口縁１４０の一部から前方に突出して後方に折り返された第１基端部２４と、第１基端部２４の後端縁２４０から角筒部１４の内方に延出された第１弾性片２３と、前端開口縁１４０のうち第１基端部２４を両側から囲む部分から前方に突出して設けられた一対の保護壁２９と、を備えた構成としたから、誤って雌端子１０を落とした際に、一対の保護壁２９によって第１基端部２４を保護することができる。 As described above, the female terminal 10 of the present embodiment has a rectangular tube shape, and protrudes forward from the rectangular tube portion 14 that opens forward at the front end opening edge 140 and a part of the front end opening edge 140 and is folded back. The first base end 24, the first elastic piece 23 extending from the rear end edge 240 of the first base end portion 24 to the inside of the square tube portion 14, and the first base end of the front end opening edge 140 And a pair of protective walls 29 provided so as to project forward from the portions surrounding the portion 24 from both sides. Therefore, when the female terminal 10 is accidentally dropped, the pair of protective walls 29 causes the first base The end 24 can be protected.
　また、一対の保護壁２９の前端は、第１基端部２４の前端よりも前方に位置している構成としたから、誤って雌端子１０を落とした際に、一対の保護壁２９が第１基端部２４よりも先に地面に衝突することになるため、第１基端部２４を確実に保護することができる。 Further, since the front ends of the pair of protective walls 29 are positioned forward of the front end of the first base end portion 24, when the female terminal 10 is accidentally dropped, the pair of protective walls 29 are Since the first base end 24 collides with the ground before the first base end 24, the first base end 24 can be reliably protected.
　また、前端開口縁１４０のうち第１基端部２４と対向する部分から前方に突出して後方に折り返された第２基端部２７と、第２基端部２７の後端縁から角筒部１４の内方に延出された第２弾性片２６と、を備えた構成としたから、誤って雌端子１０を落とした際に、一対の保護壁２９によって第２基端部２７を保護することができる。 Further, the second base end portion 27 that protrudes forward from the portion facing the first base end portion 24 of the front end opening edge 140 and is folded back backward, and the rectangular tube portion from the rear end edge of the second base end portion 27. 14 and the second elastic piece 26 extending inwardly, the second base end portion 27 is protected by the pair of protective walls 29 when the female terminal 10 is accidentally dropped. be able to.
