図３～図６を参照して、端子金具１０の作用について説明する。なお、図５及び図６における部分拡大図では、説明の便宜上、曲面部５３の形状が誇張されている。 <Action of terminal fitting 10>
The operation of the terminal fitting 10 will be described with reference to FIGS. 3 to 6. FIG. 5 and 6, the shape of the
端子金具１０の弾性接触片４０は、図３に示すように、撓み変形していない状態では、支持片５０及び第２基板部３７のいずれにも接触していない。このため、弾性接触片４０が撓みやすく、タブ９１をタブ挿入空間３０に挿入するときの挿入抵抗が小さい。また、この状態では、弾性接触片４０の後側延出部４３の前端側は、支持片５０の曲面部５３に下方から対向した状態で配置され、後側延出部４３の後端部４３Ａは、第２基板部３７に下方から対向した状態で配置される。
As shown in FIG. 3, the elastic contact piece 40 of the terminal fitting 10 is in contact with neither the support piece 50 nor the second substrate portion 37 when it is not deformed. Therefore, the elastic contact piece 40 is easily bent, and insertion resistance when inserting the tab 91 into the tab insertion space 30 is small. Also, in this state, the front end side of the rear extension portion 43 of the elastic contact piece 40 is arranged in a state of facing the curved surface portion 53 of the support piece 50 from below, and the rear end portion 43A of the rear extension portion 43 is arranged in such a state as to face the curved surface portion 53 of the support piece 50 from below. is arranged to face the second substrate portion 37 from below.
端子金具１０のタブ挿入空間３０内にタブ９１が挿入されると、タブ９１が弾性接触片４０の前側延出部４２と受け部３１との間に挟まれた状態となり、前側延出部４２を上方へ押圧しながら進入する。タブ９１から押圧された弾性接触片４０は、第１固定端３６を支点として上方へ撓み変形する。タブ９１が進入するにつれて、弾性接触片４０の撓み量が大きくなり、図４に示すように、後側延出部４３の後端部４３Ａが第２基板部３７に接触する。なお、後側延出部４３の後端部４３Ａが第２基板部３７に接触し始めた段階では、後側延出部４３の前端側は、支持片５０に接触していない。このため、弾性接触片４０は、第１固定端３６と後側延出部４３の後端部４３Ａとの前後２点で支持される。これにより、弾性接触片４０がより安定した状態となる。また、弾性接触片４０の弾性力が向上する。
When the tab 91 is inserted into the tab insertion space 30 of the terminal fitting 10 , the tab 91 is sandwiched between the front extending portion 42 of the elastic contact piece 40 and the receiving portion 31 . Enter while pressing upward. The elastic contact piece 40 pressed by the tab 91 bends and deforms upward with the first fixed end 36 as a fulcrum. As the tab 91 advances, the amount of deflection of the elastic contact piece 40 increases, and the rear end portion 43A of the rear extension portion 43 contacts the second substrate portion 37 as shown in FIG. Note that the front end side of the rear extension portion 43 is not in contact with the support piece 50 at the stage when the rear end portion 43A of the rear extension portion 43 starts contacting the second substrate portion 37 . Therefore, the elastic contact piece 40 is supported at two front and rear points, namely, the first fixed end 36 and the rear end portion 43A of the rear extension portion 43 . As a result, the elastic contact piece 40 becomes more stable. Also, the elastic force of the elastic contact piece 40 is improved.
更にタブ９１が進入すると、弾性接触片４０は、第１固定端３６と後側延出部４３の後端部４３Ａとの前後２点を支点として、その内側が上方へ撓み変形する。そして、図５に示すように、弾性接触片４０の後側延出部４３の上面が、支持片５０の曲面部５３に接触する。これにより、弾性接触片４０が支持片５０に支持された状態となり、弾性接触片４０の弾性力がより一層向上する。なお、弾性接触片４０の後側延出部４３のうち支持片５０の曲面部５３に接触する部位が第１接触部位４５であり、支持片５０の曲面部５３のうち弾性接触片４０の後側延出部４３に接触する部位が第２接触部位５４である。第１接触部位４５は、支持片５０の下面の前端に最初に接触する。
When the tab 91 further enters, the inner side of the elastic contact piece 40 bends and deforms upward with two front and rear points, the first fixed end 36 and the rear end portion 43A of the rear side extension portion 43, as fulcrums. Then, as shown in FIG. 5 , the upper surface of the rear extension portion 43 of the elastic contact piece 40 contacts the curved surface portion 53 of the support piece 50 . As a result, the elastic contact piece 40 is supported by the support piece 50, and the elastic force of the elastic contact piece 40 is further improved. A portion of the rear extension portion 43 of the elastic contact piece 40 that contacts the curved surface portion 53 of the support piece 50 is the first contact portion 45 . A portion that contacts the side extension portion 43 is the second contact portion 54 . The first contact portion 45 first contacts the front end of the lower surface of the support piece 50 .
更にタブ９１が進入すると、弾性接触片４０の撓み量が次第に大きくなる。弾性接触片４０の撓み量が大きくなるにつれて、弾性接触片４０の第１接触部位４５が支持片５０の曲面部５３に沿って第２固定端３８側に変位する。このため、支持片５０が弾性接触片４０を下方へ押し返す力は、弾性接触片４０の撓み量が大きくなるにつれて大きくなる。よって、弾性接触片４０の弾性力がより一層向上する。タブ９１が正規挿入位置まで到達すると、図６に示すように、第１接触部位４５は、支持片５０の下面の前端よりも第２固定端３８側の位置に接触した状態となる。
When the tab 91 enters further, the deflection amount of the elastic contact piece 40 gradually increases. As the amount of deflection of the elastic contact piece 40 increases, the first contact portion 45 of the elastic contact piece 40 is displaced along the curved surface portion 53 of the support piece 50 toward the second fixed end 38 . Therefore, the force with which the support piece 50 pushes the elastic contact piece 40 downward increases as the amount of deflection of the elastic contact piece 40 increases. Therefore, the elastic force of the elastic contact piece 40 is further improved. When the tab 91 reaches the normal insertion position, the first contact portion 45 comes into contact with the second fixed end 38 side of the front end of the lower surface of the support piece 50 as shown in FIG.
つまり、弾性接触片４０は、曲面部５３の第１位置Ｐ１に接触する第１状態（図５参照）と、第１状態よりも撓み量が大きい状態であって且つ曲面部５３における第１位置Ｐ１よりも第２固定端３８側の第２位置Ｐ２に接触する第２状態（図６参照）とに順次移行する。第１位置Ｐ１は、支持片５０の下面の前端である。第２位置Ｐ２は、支持片５０の下面の前端よりも第２固定端３８側の位置である。
That is, the elastic contact piece 40 is in a first state (see FIG. 5) in which the elastic contact piece 40 contacts the first position P1 of the curved surface portion 53, and in a state where the elastic contact piece 40 is bent more than in the first state and is in the first position on the curved surface portion 53. The second state (see FIG. 6) of contacting the second position P2 closer to the second fixed end 38 than P1 is sequentially changed. The first position P1 is the front end of the lower surface of the support piece 50 . The second position P2 is a position closer to the second fixed end 38 than the front end of the lower surface of the support piece 50 .
＜端子金具１０の効果＞
以上のように、端子金具１０では、本体部２０にタブ９１が挿入されて弾性接触片４０が撓み変形する場合、弾性接触片４０の撓み量が大きくなるにつれて、第１接触部位４５が支持片５０の曲面部５３に沿って第２固定端３８側に変位する。このため、タブ９１の挿入時の挿入抵抗を小さく抑えつつ、弾性接触片４０の撓み量が大きくなるにつれてタブ９１に対する弾性接触片４０の接圧を大きくすることができる。従って、端子金具１０によれば、タブ９１に対する弾性接触片４０の必要な接圧を確保しやすくなる。 <Effects of terminal fitting 10>
As described above, in the terminal fitting 10, when thetab 91 is inserted into the main body portion 20 and the elastic contact piece 40 is flexurally deformed, the first contact portion 45 becomes the support piece as the amount of deflection of the elastic contact piece 40 increases. It is displaced along the curved surface portion 53 of 50 toward the second fixed end 38 side. Therefore, the contact pressure of the elastic contact piece 40 against the tab 91 can be increased as the deflection amount of the elastic contact piece 40 increases while the insertion resistance at the time of insertion of the tab 91 is kept small. Therefore, according to the terminal fitting 10 , it becomes easier to ensure the necessary contact pressure of the elastic contact piece 40 against the tab 91 .
以上のように、端子金具１０では、本体部２０にタブ９１が挿入されて弾性接触片４０が撓み変形する場合、弾性接触片４０の撓み量が大きくなるにつれて、第１接触部位４５が支持片５０の曲面部５３に沿って第２固定端３８側に変位する。このため、タブ９１の挿入時の挿入抵抗を小さく抑えつつ、弾性接触片４０の撓み量が大きくなるにつれてタブ９１に対する弾性接触片４０の接圧を大きくすることができる。従って、端子金具１０によれば、タブ９１に対する弾性接触片４０の必要な接圧を確保しやすくなる。 <Effects of terminal fitting 10>
As described above, in the terminal fitting 10, when the
更に、端子金具１０によれば、第１接触部位４５が設けられる後側延出部４３と、第２接触部位５４が設けられる支持側延出部５２とが互いに平行又は略平行であるため、第１接触部位４５が曲面部５３に沿って支持片５０の第２固定端３８側に変位するように調整しやすい。
Furthermore, according to the terminal fitting 10, since the rear-side extension 43 provided with the first contact portion 45 and the support-side extension 52 provided with the second contact portion 54 are parallel or substantially parallel to each other, It is easy to adjust so that the first contact portion 45 is displaced along the curved surface portion 53 toward the second fixed end 38 of the support piece 50 .
