Description

本発明は、雌端子に関する。   The present invention relates to a female terminal.

一般的に雌端子は、雄端子を挿入可能な筒部と、電線等の外部回路と接続可能な接続部とを備えている。例えば、特許第４６７８３４１号公報（下記特許文献１）に開示された雌端子は、タブ状の雄端子を挿入可能な筒部と、筒部の内側に配される板バネ状の接触片と、電線との接続部とを備えている。この雌端子では、接触片はＵ字状に湾曲されており、筒部内に雄端子が挿入されると、筒部と接触片の湾曲の頂点部分との間に雄端子が挟まれることで、雄端子と雌端子が電気的に接続される。   In general, a female terminal includes a cylindrical portion into which a male terminal can be inserted and a connection portion that can be connected to an external circuit such as an electric wire. For example, the female terminal disclosed in Japanese Patent No. 4678341 (the following Patent Document 1) includes a cylindrical portion into which a tab-shaped male terminal can be inserted, a leaf spring-like contact piece disposed inside the cylindrical portion, And a connection portion with the electric wire. In this female terminal, the contact piece is curved in a U-shape, and when the male terminal is inserted into the tubular portion, the male terminal is sandwiched between the tubular portion and the apex portion of the curved contact piece, The male terminal and the female terminal are electrically connected.

特許第４６７８３４１号公報Japanese Patent No. 4678341

特許第４６７８３４１号公報（上記特許文献１）に記載の雌端子では、接触片と筒部とで挟む込む方向（上下方向）では、接触片と筒部に挟まれた雄端子は振動しにくい構造となっているが、上下方向と交差する方向（横方向すなわちタブ状の雄端子の面の広がり方向）の振動の対策は取られていない。そのため、横方向に雄端子がずれ動くことで、接点部分で摺動が発生し、接点が摩耗する虞がある。   In the female terminal described in Japanese Patent No. 4678341 (the above-mentioned Patent Document 1), the male terminal sandwiched between the contact piece and the cylindrical portion is less likely to vibrate in the direction (vertical direction) sandwiched between the contact piece and the cylindrical portion. However, no countermeasure is taken against vibration in the direction intersecting the vertical direction (lateral direction, that is, the spreading direction of the surface of the tab-shaped male terminal). Therefore, when the male terminal is displaced in the lateral direction, the contact portion may slide, and the contact may be worn.

本明細書で開示される雌端子は、一端に挿入口を設け、その挿入口から平板状の雄端子を挿入可能な端子挿入部と、前記端子挿入部の内部に配されて、前記端子挿入部の内壁との間で前記雄端子を挟む込む板バネ状の弾性接触片と、前記弾性接触片の撓み方向と直交する方向における前記端子挿入部の側面から内側に向かって突設するビード部と、前記ビード部に対向して、前記雄端子の側面に弾性的に接触することで、前記ビード部との間で前記雄端子を挟み込む挟み込み片とを備えた。   The female terminal disclosed in the present specification is provided with an insertion opening at one end, a terminal insertion portion into which a flat male terminal can be inserted from the insertion opening, and the terminal insertion portion disposed inside the terminal insertion portion. A leaf spring-like elastic contact piece that sandwiches the male terminal with the inner wall of the portion, and a bead portion projecting inward from the side surface of the terminal insertion portion in a direction orthogonal to the bending direction of the elastic contact piece And a sandwiching piece that sandwiches the male terminal with the bead portion by elastically contacting the side surface of the male terminal so as to face the bead portion.

このような構成によると、弾性接触片の撓み方向だけでなく、撓み方向と直交する方向でもビード部と挟み込み片によって雄端子を挟み込むことで、雄端子の振動によるずれを抑制することができる。   According to such a configuration, the male terminal is sandwiched between the bead portion and the sandwiching piece not only in the bending direction of the elastic contact piece but also in the direction orthogonal to the bending direction, so that a shift due to vibration of the male terminal can be suppressed.

本明細書に開示される雌端子の実施の態様として、以下の構成としても良い。
前記弾性接触片は、前記端子挿入部の壁部を構成する材料と別体とされており、前記挟み込み片は、前記弾性接触片と一体とされている構成としても良い。 As an embodiment of the female terminal disclosed in this specification, the following configuration may be adopted.
The elastic contact piece may be separate from the material constituting the wall portion of the terminal insertion portion, and the sandwiching piece may be integrated with the elastic contact piece.

このような構成では、弾性接触片と挟み込み片を端子挿入部とは別材料や別の厚さで作成することができる。また、弾性接触片と挟み込み片が一体となっているため、弾性接触片を端子挿入部内に組み込む際に一緒に挟み込み片も組み込むことができる。   In such a configuration, the elastic contact piece and the sandwiching piece can be made of a material different from that of the terminal insertion portion and a different thickness. Moreover, since the elastic contact piece and the sandwiching piece are integrated, the sandwiching piece can be incorporated together when the elastic contact piece is incorporated into the terminal insertion portion.

前記端子挿入部の前記弾性接触片と対向する側面には、前記雄端子の挿入方向に延びる接点部が突設されている構成としても良い。   It is good also as a structure by which the contact part extended in the insertion direction of the said male terminal is protrudingly provided in the side surface facing the said elastic contact piece of the said terminal insertion part.

このような構成では、雄端子と雌端子との接点が、接点部とビード部とになり、接点数が増えることになる。   In such a configuration, the contact between the male terminal and the female terminal becomes a contact portion and a bead portion, and the number of contacts increases.

本明細書に開示された雌端子によれば、雄端子が幅方向に振動するのを抑制することができる。   According to the female terminal disclosed in this specification, it is possible to suppress the male terminal from vibrating in the width direction.

図５及び図６に示すように、左側の側壁部５５Ａの下端部の前端縁には、保護片６５が設けられている。保護片６５は、左側の側壁部５５Ａの前端縁から板厚分前方に突出した後内側に直角に曲げられ、さらに直角に曲げられて後方に折り返すようにして形成されている。保護片６５は、雄端子８０が返し片５９の端部と当接しないようにするために設けられている。保護片６５は、返し片５９の端部の幅方向における位置と同じ位置まで内側に突出している。保護片６５の上下方向の寸法は、挟み込み片５７及び返し片５９の上下方向の寸法より若干大きくなっている。また、返し片５９の上下方向の位置は、挟み込み片５７の上下方向の位置とほぼ同じになっている。   As shown in FIGS. 5 and 6, a protective piece 65 is provided at the front end edge of the lower end portion of the left side wall portion 55A. The protective piece 65 is formed so as to protrude forward from the front edge of the left side wall portion 55A by a thickness and then bend at a right angle, and further bent at a right angle and folded back. The protective piece 65 is provided to prevent the male terminal 80 from coming into contact with the end of the return piece 59. The protective piece 65 protrudes inward to the same position as the position in the width direction of the end of the return piece 59. The vertical dimension of the protective piece 65 is slightly larger than the vertical dimension of the sandwiching piece 57 and the return piece 59. The vertical position of the return piece 59 is substantially the same as the vertical position of the sandwiching piece 57.

雄端子８０は、大電流用の太い電線に対応して比較的厚肉の導電性板材をプレス加工することにより形成されている。雄端子８０は、後部が図示しない電線に接続されており、図８及び図９に示すように、前部が平板状のタブ部８１とされている。また、雄端子８０のタブ部８１の前側には、幅方向外側に突出して位置決め片６３及び保護片６５と当接する当接部８３が設けられている。当接部８３は、タブ部８１よりも幅方向の寸法が大きくなっており、端子挿入部２３の挿入口２３Ａの幅方向の内寸法よりも大きくなっている。そして、当接部８３が位置決め片６３及び保護片６５に当接することで、雄端子８０がそれ以上後方に挿入されなくなる。   The male terminal 80 is formed by pressing a relatively thick conductive plate corresponding to a thick electric wire for large current. The rear part of the male terminal 80 is connected to a wire (not shown), and the front part is a flat tab part 81 as shown in FIGS. Further, on the front side of the tab portion 81 of the male terminal 80, a contact portion 83 that protrudes outward in the width direction and contacts the positioning piece 63 and the protective piece 65 is provided. The contact portion 83 is larger in the width direction than the tab portion 81 and larger than the inner dimension in the width direction of the insertion port 23 </ b> A of the terminal insertion portion 23. And since the contact part 83 contact | abuts to the positioning piece 63 and the protection piece 65, the male terminal 80 is no longer inserted back.

次に、雌端子１０の組み立て手順及び雄端子８０との接続手順の一例について説明する。
まず、バネ部材５０をプレス加工によって打ち抜いて、図４に示すように、折り曲げ成形する。この際に、展開状態のバネ部材５０は、挟み込み片５７が弾性接触片５３と同じ後方に延びているため、打ち抜く際の材料ロスを抑制でき、歩留まりがよくなる。 Next, an example of the assembly procedure of the female terminal 10 and the connection procedure with the male terminal 80 will be described.
First, the spring member 50 is punched out by press working, and is bent as shown in FIG. At this time, since the sandwiched piece 57 extends in the same rear as the elastic contact piece 53, the unfolded spring member 50 can suppress material loss when punching, and the yield is improved.

そして、図１及び図２に示すように、折り曲げ成形されたバネ部材５０を端子挿入部２３内に配置する。具体的には、展開状態にある端子挿入部２３の内側に、バネ部材５０を配し、その状態から幅方向に折り曲げて、端子挿入部２３を成型する。端子挿入部２３の側面部２７の立ち上げに伴って、端子挿入部２３の係止孔３３にバネ部材５０の係止片６１を進入させる。そして、係止片６１が係止孔３３の孔縁に係止されることで、前後及び上下方向に位置決めされる。また、位置決め片６３が端子挿入部２３の側面部２７の前面に当接することで、バネ部材５０が後方にずれないようになっている。そして、対向部２９が曲げられて過撓み防止片３７が曲げられることで、弾性接触片５３の下端部５３Ａの上方に過撓み防止片３７が配される。このようにして、バネ部材５０は端子挿入部２３内に位置決めされて保持されて、雌端子１０が組み立てられる。   Then, as shown in FIGS. 1 and 2, the bent spring member 50 is disposed in the terminal insertion portion 23. Specifically, the spring member 50 is arranged inside the terminal insertion portion 23 in the unfolded state, and the terminal insertion portion 23 is molded by bending in the width direction from that state. As the side surface portion 27 of the terminal insertion portion 23 rises, the locking piece 61 of the spring member 50 enters the locking hole 33 of the terminal insertion portion 23. And the locking piece 61 is positioned by the hole edge of the locking hole 33, and is positioned in the front-back direction and the up-down direction. Further, since the positioning piece 63 contacts the front surface of the side surface portion 27 of the terminal insertion portion 23, the spring member 50 is prevented from shifting backward. Then, the over-deflection preventing piece 37 is arranged above the lower end portion 53 </ b> A of the elastic contact piece 53 by bending the opposing portion 29 and bending the over-deflection preventing piece 37. Thus, the spring member 50 is positioned and held in the terminal insertion portion 23, and the female terminal 10 is assembled.

次に、雄端子８０を雌端子１０に挿入する。端子挿入部２３内にバネ部材５０が配置され、弾性接触片５３及び挟み込み片５７が自然状態にある状態で、雄端子８０が端子挿入部２３の挿入口２３Ａから挿入される。図８及び図９に示すように、雄端子８０が挿入されると、雄端子８０のタブ部８１の前端部が弾性接触片５３の下端部５３Ａと弾性的に接触し、弾性接触片５３を押し上げて撓み変形させる。そして、雄端子８０のタブ部８１が弾性接触片５３と接点部２５との間に挟み込まれる。   Next, the male terminal 80 is inserted into the female terminal 10. The male member 80 is inserted from the insertion port 23A of the terminal insertion portion 23 in a state where the spring member 50 is disposed in the terminal insertion portion 23 and the elastic contact piece 53 and the sandwiching piece 57 are in a natural state. As shown in FIGS. 8 and 9, when the male terminal 80 is inserted, the front end portion of the tab portion 81 of the male terminal 80 comes into elastic contact with the lower end portion 53 </ b> A of the elastic contact piece 53. Push up to bend and deform. Then, the tab portion 81 of the male terminal 80 is sandwiched between the elastic contact piece 53 and the contact portion 25.

そして、雄端子８０をさらに進入させると、雄端子８０のタブ部８１の左側の側面が挟み込み片５７の凸部５８に接触して、挟み込み片５７を幅方向外側に撓み変形させる。同時に、雄端子８０のタブ部８１の右側の側面に、ビード部３１が接触することで、雄端子８０が挟み込み片５７とビード部３１との間に幅方向でも挟み込まれる。なお、雄端子８０が挿入口２３Ａの左側に位置ずれして挿入されても、保護片６５が挟み込み片５７を保護しているため、雄端子８０のタブ部８１の先端部が返し片５９に当たって挟み込み片５７を前方から押しつぶすことを抑制できる。また、挟み込み片５７の凸部５８が、弾性接触片５３の下端部５３Ａの後方に位置しており、雄端子８０が弾性接触片５３を撓み変形させるタイミングと、挟み込み片５７の凸部５８が撓み変形するタイミングとがずれるため、雄端子８０の挿入力を抑制することができる。   When the male terminal 80 is further advanced, the left side surface of the tab portion 81 of the male terminal 80 comes into contact with the convex portion 58 of the sandwiching piece 57, and the sandwiching piece 57 is bent and deformed outward in the width direction. At the same time, the bead portion 31 comes into contact with the right side surface of the tab portion 81 of the male terminal 80, so that the male terminal 80 is also sandwiched between the sandwiching piece 57 and the bead portion 31 in the width direction. Even if the male terminal 80 is inserted to the left side of the insertion port 23 </ b> A, the protective piece 65 protects the sandwiching piece 57, so that the tip of the tab portion 81 of the male terminal 80 hits the return piece 59. Crushing of the sandwiching pieces 57 from the front can be suppressed. Further, the convex portion 58 of the sandwiching piece 57 is located behind the lower end portion 53A of the elastic contact piece 53, the timing at which the male terminal 80 bends and deforms the elastic contact piece 53, and the convex portion 58 of the sandwiching piece 57 is provided. Since the timing of bending deformation is shifted, the insertion force of the male terminal 80 can be suppressed.

さらに後方に雄端子８０が挿入されると、当接部８３が位置決め片６３及び保護片６５に当接して、挿入が停止される。そして、位置決め片６３が当接部８３と側面部２７との前面の間に挟み込まれる。   When the male terminal 80 is further inserted rearward, the contact portion 83 contacts the positioning piece 63 and the protection piece 65, and the insertion is stopped. Then, the positioning piece 63 is sandwiched between the front surfaces of the contact portion 83 and the side surface portion 27.

このようにして、雄端子８０のタブ部８１が弾性接触片５３によって下方に（接点部２５側）に押し付けられることで、雄端子８０と接点部２５との接触が確保されて雄端子８０と雌端子１０が電気的に接続される。また、雄端子８０が弾性接触片５３と接点部２５との間に挟み込まれることで、雄端子８０が上下方向に移動することが抑制される。一方で、雄端子８０が挟み込み片５７によって右側（ビード部３１側）に押し付けられることで、雄端子８０とビード部３１との接触が確保されて、電気的に接続される接点数が増える。また、挟み込み片５７とビード部３１との間に挟み込まれることで、雄端子８０が幅方向に移動することが抑制される。   In this manner, the tab portion 81 of the male terminal 80 is pressed downward (contact point 25 side) by the elastic contact piece 53, so that the contact between the male terminal 80 and the contact portion 25 is ensured, and the male terminal 80 and The female terminal 10 is electrically connected. Further, since the male terminal 80 is sandwiched between the elastic contact piece 53 and the contact portion 25, the male terminal 80 is suppressed from moving in the vertical direction. On the other hand, when the male terminal 80 is pressed to the right side (bead part 31 side) by the sandwiching piece 57, the contact between the male terminal 80 and the bead part 31 is ensured, and the number of contacts to be electrically connected increases. Further, the male terminal 80 is suppressed from moving in the width direction by being sandwiched between the sandwiching piece 57 and the bead portion 31.

以上のように、本実施形態では、弾性接触片５３の撓み方向だけでなく、撓み方向と直交する方向でもビード部３１と挟み込み片５７によって雄端子８０を挟み込むことで、雄端子８０の振動によるずれを抑制することができる。   As described above, in the present embodiment, the male terminal 80 is sandwiched by the bead portion 31 and the sandwiching piece 57 not only in the bending direction of the elastic contact piece 53 but also in the direction orthogonal to the bending direction. Deviation can be suppressed.

＜実施形態２＞
次に、実施形態２を図１０から図１８によって説明する。
実施形態２の雌端子１１０では、バネ部材１５０の形状が、実施形態１とは相違する。なお、実施形態１と同一機能を有する部材、部位については、同一の符号を付すことで、説明を省略しまたは簡略化する。また、上下前後方向については、実施形態１と同じ方向とする。 <Embodiment 2>
Next, Embodiment 2 will be described with reference to FIGS.
In the female terminal 110 of the second embodiment, the shape of the spring member 150 is different from that of the first embodiment. In addition, about the member and site | part which have the same function as Embodiment 1, description is abbreviate | omitted or simplified by attaching | subjecting the same code | symbol. The vertical direction is the same as that in the first embodiment.

雌端子１１０は、図１０に示すように、端子本体部２０と、端子本体部２０とは別体のバネ部材１５０とを備えている。そして、雌端子１１０は、雄端子８０と接続される。   As shown in FIG. 10, the female terminal 110 includes a terminal main body 20 and a spring member 150 that is separate from the terminal main body 20. The female terminal 110 is connected to the male terminal 80.

バネ部材１５０は、ステンレス等の強度に優れた材料を用いており、端子本体部２０よりも板厚が薄くなっている。バネ部材１５０は、バネ本体部５１と、弾性接触片１５３と、一対の側壁部５５と、左側の側壁部５５Ａの端部から延びる挟み込み片１５７とを備えている。また、バネ部材１５０には、係止片６１と位置決め片６３が設けられている。   The spring member 150 is made of a material having excellent strength, such as stainless steel, and is thinner than the terminal main body 20. The spring member 150 includes a spring body 51, an elastic contact piece 153, a pair of side wall portions 55, and a sandwiching piece 157 extending from the end of the left side wall portion 55A. The spring member 150 is provided with a locking piece 61 and a positioning piece 63.

弾性接触片１５３は、図１３及び図１５に示すように、バネ本体部５１の幅方向の中央位置に設けられており、上下方向に弾性変形可能な帯状の板バネとなっている。弾性接触片１５３の幅方向の寸法は、バネ本体部５１の幅方向の寸法より狭くなっており、雄端子８０（図１８参照）の幅方向の寸法よりも狭くなっている。なお、弾性接触片１５３の幅方向の寸法は、実施形態１の弾性接触片５３の幅寸法よりも若干大きくなっている。   As shown in FIGS. 13 and 15, the elastic contact piece 153 is provided at a central position in the width direction of the spring body 51 and is a strip-shaped plate spring that can be elastically deformed in the vertical direction. The dimension of the elastic contact piece 153 in the width direction is narrower than the dimension of the spring body 51 in the width direction, and is narrower than the dimension of the male terminal 80 (see FIG. 18) in the width direction. Note that the width dimension of the elastic contact piece 153 is slightly larger than the width dimension of the elastic contact piece 53 of the first embodiment.

挟み込み片１５７は、図１４及び図１８に示すように、左側の側壁部５５Ａの下端部の前端縁から後方に折り返された片が内側に入り込むことで形成されている。挟み込み片１５７は、幅方向に撓み変形可能となっている。挟み込み片１５７の最も内側に入り込んだところには、幅方向内側（雄端子８０に近接する側）に向かってＵ字状に突出した凸部１５８が設けられている。挟み込み片１５７の上下方向の寸法は、側壁部５５の上下方向の寸法の略半分程度となっており、雄端子８０の上下方向の寸法と同じ程度となっている。挟み込み片１５７の端子挿入部２３における上下方向の位置は、ビード部３１の上下方向の位置とほぼ同じになっている。挟み込み片１５７の凸部１５８は、ビード部３１の前後方向の寸法内に配されており、弾性接触片１５３の下端部１５３Ａよりも後方に位置している。そして、挟み込み片１５７の凸部１５８とビード部３１との間の寸法は、自然状態では、雄端子８０の後記するタブ部８１の幅方向の外寸よりも小さくなっている。   As shown in FIGS. 14 and 18, the sandwiching piece 157 is formed by a piece folded back from the front end edge of the lower end portion of the left side wall portion 55 </ b> A entering the inside. The sandwiching piece 157 can be bent and deformed in the width direction. A convex portion 158 that protrudes in a U shape toward the inner side in the width direction (side close to the male terminal 80) is provided at the innermost portion of the sandwiching piece 157. The vertical dimension of the sandwiching piece 157 is approximately half of the vertical dimension of the side wall 55 and is approximately the same as the vertical dimension of the male terminal 80. The vertical position of the sandwiching piece 157 in the terminal insertion portion 23 is substantially the same as the vertical position of the bead portion 31. The convex portion 158 of the sandwiching piece 157 is arranged within the dimension in the front-rear direction of the bead portion 31 and is located behind the lower end portion 153A of the elastic contact piece 153. And the dimension between the convex part 158 of the pinching piece 157 and the bead part 31 is smaller than the external dimension of the width direction of the tab part 81 which the male terminal 80 mentions later in a natural state.

次に、雌端子１１０の組み立て手順及び雄端子８０との接続手順の一例について説明する。
まず、バネ部材１５０をプレス加工によって打ち抜いて、図４に示すように、折り曲げ成形する。この際に、展開状態のバネ部材１５０は、挟み込み片１５７が弾性接触片５３の延び方向とは異なる方向（前方）に延びている。そのため、挟み込み片１５７の寸法に係らず、弾性接触片１５３の幅寸法を決めれるため、弾性接触片１５３の幅寸法を大きくすることができ、弾性接触片１５３の弾性力を実施形態１に比べて向上することができる。 Next, an example of the assembly procedure of the female terminal 110 and the connection procedure with the male terminal 80 will be described.
First, the spring member 150 is punched out by press working, and is bent as shown in FIG. At this time, the unfolded spring member 150 has the sandwiching piece 157 extending in a direction (forward) different from the extending direction of the elastic contact piece 53. Therefore, since the width dimension of the elastic contact piece 153 can be determined regardless of the size of the sandwiching piece 157, the width dimension of the elastic contact piece 153 can be increased, and the elastic force of the elastic contact piece 153 is larger than that of the first embodiment. Can be improved.

そして、図１０及び図１１に示すように、折り曲げ成形されたバネ部材１５０を端子挿入部２３内に配置にする。実施形態１と同様に、バネ部材１５０は端子挿入部２３内に位置決めされて保持されて、雌端子１１０が組み立てられる。   Then, as shown in FIGS. 10 and 11, the bent spring member 150 is disposed in the terminal insertion portion 23. As in the first embodiment, the spring member 150 is positioned and held in the terminal insertion portion 23, and the female terminal 110 is assembled.

次に、雄端子８０を雌端子１１０に挿入する。端子挿入部２３内にバネ部材１５０が配置され、弾性接触片５３及び挟み込み片５７が自然状態にある状態で、雄端子８０が端子挿入部２３の挿入口２３Ａから挿入される。図１７及び図１８に示すように、雄端子８０が挿入されると、雄端子８０のタブ部８１の前端部が弾性接触片１５３の下端部１５３Ａと弾性的に接触し、弾性接触片１５３を押し上げて撓み変形させる。そして、雄端子８０のタブ部８１が弾性接触片１５３と接点部２５との間に挟み込まれる。   Next, the male terminal 80 is inserted into the female terminal 110. The spring member 150 is disposed in the terminal insertion portion 23, and the male terminal 80 is inserted from the insertion port 23A of the terminal insertion portion 23 in a state where the elastic contact piece 53 and the sandwiching piece 57 are in a natural state. 17 and 18, when the male terminal 80 is inserted, the front end portion of the tab portion 81 of the male terminal 80 is in elastic contact with the lower end portion 153A of the elastic contact piece 153, and the elastic contact piece 153 is moved. Push up to bend and deform. The tab portion 81 of the male terminal 80 is sandwiched between the elastic contact piece 153 and the contact portion 25.

そして、雄端子８０をさらに進入させると、雄端子８０のタブ部８１の左側の側面が挟み込み片１５７の凸部１５８に接触して、挟み込み片１５７を幅方向外側に撓み変形させる。同時に、雄端子８０のタブ部８１が弾性接触片１５３と接点部２５との間に挟み込まれる。また、雄端子８０のタブ部８１の右側の側面に、ビード部３１が接触することで、雄端子８０が挟み込み片１５７とビード部３１との間に幅方向でも挟み込まれる。なお、挟み込み片１５７の凸部１５８が、弾性接触片１５３の下端部１５３Ａの後方に位置しており、雄端子８０が弾性接触片１５３を撓み変形させるタイミングと、挟み込み片５７の凸部５８が撓み変形するタイミングとがずれるため、雄端子８０の挿入力を抑制することができる。   When the male terminal 80 is further advanced, the left side surface of the tab portion 81 of the male terminal 80 comes into contact with the convex portion 158 of the sandwiching piece 157, and the sandwiching piece 157 is bent and deformed outward in the width direction. At the same time, the tab portion 81 of the male terminal 80 is sandwiched between the elastic contact piece 153 and the contact portion 25. Further, the bead portion 31 is in contact with the right side surface of the tab portion 81 of the male terminal 80, so that the male terminal 80 is also sandwiched between the sandwiching piece 157 and the bead portion 31 in the width direction. Note that the convex portion 158 of the sandwiching piece 157 is located behind the lower end portion 153A of the elastic contact piece 153, the timing at which the male terminal 80 bends and deforms the elastic contact piece 153, and the convex portion 58 of the sandwiching piece 57. Since the timing of bending deformation is shifted, the insertion force of the male terminal 80 can be suppressed.

さらに後方に雄端子８０が挿入されると、当接部８３が位置決め片６３に当接して、挿入が停止される。そして、位置決め片６３が当接部８３と側面部２７との前面の間に挟み込まれる。   When the male terminal 80 is further inserted rearward, the contact portion 83 contacts the positioning piece 63 and the insertion is stopped. Then, the positioning piece 63 is sandwiched between the front surfaces of the contact portion 83 and the side surface portion 27.

このようにして、雄端子８０のタブ部８１が弾性接触片１５３によって下方に（接点部２５側）に押し付けられることで、雄端子８０と接点部２５との接触が確保されて雄端子８０と雌端子１０が電気的に接続される。また、雄端子８０が弾性接触片１５３と接点部２５との間に挟み込まれることで、雄端子８０が上下方向に移動することが抑制される。一方で、雄端子８０が挟み込み片１５７によって右側（ビード部３１側）に押し付けられることで、雄端子８０とビード部３１との接触が確保されて、電気的に接続される接点数が増える。また、挟み込み片１５７とビード部３１との間に挟み込まれることで、雄端子８０が幅方向に移動することが抑制される。   In this manner, the tab portion 81 of the male terminal 80 is pressed downward (contact point 25 side) by the elastic contact piece 153, so that the contact between the male terminal 80 and the contact portion 25 is ensured, and the male terminal 80 and The female terminal 10 is electrically connected. Further, since the male terminal 80 is sandwiched between the elastic contact piece 153 and the contact portion 25, the male terminal 80 is suppressed from moving in the vertical direction. On the other hand, when the male terminal 80 is pressed to the right side (bead part 31 side) by the sandwiching piece 157, the contact between the male terminal 80 and the bead part 31 is ensured, and the number of contacts to be electrically connected increases. Further, the male terminal 80 is suppressed from moving in the width direction by being sandwiched between the sandwiching piece 157 and the bead portion 31.
