このように箱部９外に出された接点部１３は、ハウジング３の高さ方向に対向する一対の接点部１３，１３となる。   The contact portions 13 that are thus out of the box portion 9 become a pair of contact portions 13, 13 that face each other in the height direction of the housing 3.

この一対の接点部１３，１３間には、ハウジング３の挿入部７に基板ユニット２３が挿入されることにより、基板ユニット２３の端部が挿入され、回路基板５の導体部と接点部１３，１３とが接触されて基板ユニット２３と複数の端子１１とが電気的に接続される。   By inserting the board unit 23 into the insertion portion 7 of the housing 3, the end of the board unit 23 is inserted between the pair of contact portions 13, 13, and the conductor of the circuit board 5 and the contact portion 13, 13 are inserted. 13 are brought into contact with each other to electrically connect the board unit 23 and the plurality of terminals 11.

このとき、弾性片１５の自由端側の下面が押上部１９の上面と当接し、弾性片１５の箱部９内への変位が規制されているので、弾性片１５の弾性力が高められ、接点部１３，１３と回路基板５の導体部との接触圧力を高めることができ、基板ユニット２３と複数の端子１１との接続信頼性を向上することができる。   At this time, the lower surface of the elastic piece 15 on the free end side is in contact with the upper surface of the push-up portion 19, and the displacement of the elastic piece 15 into the box portion 9 is regulated. The contact pressure between the contact portions 13 and the conductor portion of the circuit board 5 can be increased, and the connection reliability between the board unit 23 and the plurality of terminals 11 can be improved.

このようなコネクタ１において、ホルダ１７を挿入部７に挿入することにより、押上部１９の先端側の傾斜面に弾性片１５の自由端側を摺動させて弾性片１５を変位させている。   In such a connector 1, by inserting the holder 17 into the insertion portion 7, the elastic piece 15 is displaced by sliding the free end side of the elastic piece 15 on the inclined surface on the tip side of the push-up portion 19.

しなしながら、弾性片１５の自由端側の位置がある程度、箱部９の外側に変位していないと、ホルダ１７を挿入部７に挿入したときに、押上部１９の先端と弾性片１５の自由端である先端とが衝突するどつきが発生し、弾性片１５に変形が生じる恐れがあった。   However, if the position of the elastic piece 15 on the free end side is not displaced to the outside of the box part 9 to some extent, when the holder 17 is inserted into the insertion part 7, the tip of the push-up part 19 and the elastic piece 15 There is a risk that the elastic piece 15 may be deformed due to the collision of the free end with the free end.

そこで、端子１１を係止する係止ランス２１は、端子１１を係止した状態で、箱部９側の面が箱部９の上壁に形成された孔から箱部９の内部に挿入され、弾性片１５と当接して弾性片１５の押上部１９側である自由端側を押上部１９の先端より箱部９の外側に変位させる。   Then, the locking lance 21 for locking the terminal 11 is inserted into the box 9 through the hole formed on the upper wall of the box 9 with the surface on the box 9 side in a state where the terminal 11 is locked. Then, the free end side of the elastic piece 15, which is the push-up portion 19 side, is displaced from the tip of the push-up portion 19 to the outside of the box 9 by contacting the elastic piece 15.

このように係止ランス２１によって弾性片１５の自由端側を押上部１９の先端より箱部９の外側に変位させることにより、ホルダ１７を挿入部７に挿入したときに、押上部１９の先端と弾性片１５の自由端とがどつくことがなく、どつきによる弾性片１５の変形を防止することができる。   By displacing the free end side of the elastic piece 15 to the outside of the box portion 9 from the tip of the push-up portion 19 by the locking lance 21 in this manner, when the holder 17 is inserted into the insertion portion 7, the tip of the push-up portion 19 And the free end of the elastic piece 15 does not stick, and the deformation of the elastic piece 15 due to sticking can be prevented.

加えて、ホルダ１７を挿入部７に挿入するときには、弾性片１５の自由端側が押上部１９の先端より箱部９の外側に変位されているので、押上部１９の先端を弾性片１５の自由端側の下面に挿入することができ、押上部１９によって確実に弾性片１５を変位させて接点部１３を確実に箱部９の外部に露出させることができる。   In addition, when the holder 17 is inserted into the insertion portion 7, the free end side of the elastic piece 15 is displaced from the tip of the push-up portion 19 to the outside of the box portion 9. It can be inserted into the lower surface on the end side, and the elastic piece 15 can be reliably displaced by the push-up portion 19 so that the contact portion 13 can be reliably exposed to the outside of the box portion 9.

しかも、弾性片１５の自由端側を押上部１９の先端より箱部９の外側に変位させる係止ランス２１は、端子１１を係止する部材であるので、弾性片１５を変位させる別部材を追加する必要がなく、部品点数の増加や配置スペースの確保によるハウジング３の大型化を引き起こすことがない。   In addition, since the locking lance 21 for displacing the free end side of the elastic piece 15 from the tip of the push-up portion 19 to the outside of the box portion 9 is a member for locking the terminal 11, another member for displacing the elastic piece 15 is required. There is no need to add them, and there is no increase in the size of the housing 3 due to an increase in the number of components and an arrangement space.

このようなコネクタ１では、係止ランス２１が、端子１１の箱部９内に挿入され弾性片１５と当接して弾性片１５の押上部１９側を押上部１９の先端より箱部９の外側に変位させているので、ホルダ１７をハウジング３の挿入部７に組付けるときに、ホルダ１７の押上部１９の先端と端子１１の弾性片１５の先端とが衝突することがなく、弾性片１５の変形を防止して所望の接触荷重を得ることができる。   In such a connector 1, the locking lance 21 is inserted into the box portion 9 of the terminal 11 and comes into contact with the elastic piece 15 so that the push-up portion 19 side of the elastic piece 15 is located outside the box portion 9 from the tip of the push-up portion 19. When the holder 17 is assembled to the insertion portion 7 of the housing 3, the tip of the push-up portion 19 of the holder 17 does not collide with the tip of the elastic piece 15 of the terminal 11. , And a desired contact load can be obtained.

従って、このようなコネクタ１では、ホルダ１７をハウジング３の挿入部７に組付けるときのホルダ１７の押上部１９の先端と端子１１の弾性片１５の先端とのどつきを防止でき、ホルダ１７の組付けによる弾性片１５の変形を防止することができる。   Therefore, in such a connector 1, it is possible to prevent the tip of the push-up portion 19 of the holder 17 and the tip of the elastic piece 15 of the terminal 11 from being throbbed when the holder 17 is attached to the insertion portion 7 of the housing 3. Deformation of the elastic piece 15 due to assembly can be prevented.

また、押上部１９は、弾性片１５の自由端と当接し弾性片１５の箱部９内への変位を規制しているので、弾性片１５の接点部１３における接触圧力を高めることができ、電気的な接続信頼性を向上することができる。   Further, since the push-up portion 19 is in contact with the free end of the elastic piece 15 and regulates the displacement of the elastic piece 15 into the box portion 9, the contact pressure at the contact portion 13 of the elastic piece 15 can be increased, Electrical connection reliability can be improved.

なお、本発明の実施の形態に係るコネクタでは、ハウジングの幅方向に複数列配置された複数の端子が２段配置されているが、これに限らず、４段以上配置させるなど、基板ユニットの端部が挿入される挿入部を複数設けてもよい。   In the connector according to the embodiment of the present invention, a plurality of terminals arranged in a plurality of rows in the width direction of the housing are arranged in two stages. However, the present invention is not limited to this. A plurality of insertion portions into which the ends are inserted may be provided.

また、端子の接点部は、端子を上下対称に配置させることによって一対の接触部となっているが、これに限らず、１つの端子に一対の接点部を設けてもよい。   Further, the contact portions of the terminals are formed as a pair of contact portions by arranging the terminals vertically symmetrically. However, the present invention is not limited to this, and a pair of contact portions may be provided for one terminal.

この場合には、例えば、端子収容室内に箱部に係合される係止ランスを一対設け、それぞれの係止ランスによって接点部が設けられた弾性片を変位させればよい。   In this case, for example, a pair of locking lances to be engaged with the box portion may be provided in the terminal receiving chamber, and the respective elastic lances provided with the contact portions may be displaced by the respective locking lances.
