この相手コネクタ３５は、露出された回路基板３９側の端部が基板ハウジング３７の外周に設けられた一対のガイドリブ（図示略）とハウジング３に設けられた一対のガイド溝４３，４３とを介してハウジング３のフード部１７内に挿入され、基板ハウジング３７とハウジング３とに設けられた係止部４７（基板ハウジング側の係止部は図示略）を介して係止される。   The mating connector 35 is connected to a pair of guide ribs (not shown) provided on the outer periphery of the substrate housing 37 and a pair of guide grooves 43, 43 provided in the housing 3. Are inserted into the hood portion 17 of the housing 3 and locked through a locking portion 47 (the locking portion on the substrate housing side is not shown) provided in the substrate housing 37 and the housing 3.

このように相手コネクタ３５の回路基板３９側の端部をハウジング３のフード部１７内に収容することにより、相手コネクタ３５の回路基板３９がホルダ１１を挿通して一対の接触部３１，３１間に挿入される。これにより、一対の接触部３１，３１が回路基板３９の導体部に接続され、相手コネクタ３５と複数の端子７とが導通される。   Thus, by accommodating the end of the mating connector 35 on the circuit board 39 side in the hood 17 of the housing 3, the circuit board 39 of the mating connector 35 is inserted through the holder 11 and between the pair of contact portions 31, 31. Inserted into. As a result, the pair of contact portions 31, 31 are connected to the conductor portion of the circuit board 39, and the mating connector 35 and the plurality of terminals 7 are electrically connected.

なお、ハウジング３と相手コネクタ３５との間には、ハウジング３のフード部１７内に収容配置され、ハウジング３と基板ハウジング３７とに密着してハウジング３と相手コネクタ３５との間を防水するパッキン４９が配置される。   In addition, between the housing 3 and the mating connector 35, it is accommodated in the hood part 17 of the housing 3, and is tightly attached to the housing 3 and the substrate housing 37 to waterproof between the housing 3 and the mating connector 35. 49 is arranged.

このようなコネクタ１において、複数の押上部１３は、端子７の接続部５側に向けて延設された延設長さが２種類の長さＬ１，Ｌ２に設定されている。詳細には、複数の押上部１３は、ホルダ１１の幅方向において、隣り合う押上部１３，１３が異なる延設長さＬ１，Ｌ２を有するように交互に配列され、ホルダ１１の高さ方向において、上下に対向する押上部１３，１３が異なる延設長さＬ１，Ｌ２を有するように配置されている。   In such a connector 1, the plurality of push-up portions 13 are set to have two lengths L <b> 1 and L <b> 2 that extend toward the connection portion 5 side of the terminal 7. Specifically, the plurality of push-up portions 13 are alternately arranged so that adjacent push-up portions 13 and 13 have different extending lengths L1 and L2 in the width direction of the holder 11, and in the height direction of the holder 11 The upper and lower push-up portions 13, 13 are arranged to have different extending lengths L1, L2.

この延設長さＬ１，Ｌ２は、長い延設長さＬ１を有する押上部１３が接点部９を最大に変位させた後、短い延設長さＬ２を有する押上部１３が接点部９の先端と当接して接点部９の変位を開始させるように設定されている。   The extended lengths L1 and L2 are such that after the push-up portion 13 having the long extended length L1 displaces the contact portion 9 to the maximum, the push-up portion 13 having the short extended length L2 becomes the tip of the contact portion 9. Is set so as to start displacement of the contact portion 9.

このように複数の押上部１３の延設長さＬ１，Ｌ２を設定することにより、押上部１３によって接点部９を変位させる変位力のピークに到達するタイミングを延設長さＬ１を有する押上部１３と延設長さＬ２を有する押上部１３とで分けることができる。   By setting the extension lengths L1 and L2 of the plurality of push-up portions 13 in this way, the push-up portion having the extension length L1 at the timing when the peak of the displacement force that displaces the contact portion 9 by the push-up portions 13 is reached. 13 and the push-up portion 13 having the extended length L2.

このため、ハウジング３とホルダ１１との挿入範囲において、従来のような全ての接点部９を変位させる変位力のピークが同時に到達される押上部１３に比較して、複数の押上部１３による接点部９の変位力を分けることができ、ハウジング３とホルダ１１との挿入抵抗を軽減することができる。   For this reason, in the insertion range of the housing 3 and the holder 11, as compared with the push-up unit 13 where the peak of the displacement force for displacing all the contact units 9 as in the prior art is reached simultaneously, the contact points by the plurality of push-up units 13 The displacement force of the part 9 can be divided, and the insertion resistance between the housing 3 and the holder 11 can be reduced.

このようなコネクタ１では、複数の押上部１３が端子７の接続部５側に向けて延設された延設長さが２種類の長さＬ１，Ｌ２に設定されているので、ハウジング３とホルダ１１との組付において、押上部１３による接点部９を変位させるタイミングが２段階に分けられ、ハウジング３とホルダ１１との挿入抵抗を軽減することができる。すなわち、複数の押上部１３の延設長さを変えているため、押上部１３による接点部９を変位させるタイミングをずらすことができる。これにより、ハウジング３に対するホルダ１１の挿入力を軽減することができる。   In such a connector 1, the extension lengths of the plurality of push-up portions 13 extending toward the connection portion 5 side of the terminal 7 are set to two types of lengths L 1 and L 2. In the assembly with the holder 11, the timing of displacing the contact portion 9 by the push-up portion 13 is divided into two stages, and the insertion resistance between the housing 3 and the holder 11 can be reduced. That is, since the extending length of the plurality of push-up portions 13 is changed, the timing for displacing the contact portion 9 by the push-up portions 13 can be shifted. Thereby, the insertion force of the holder 11 with respect to the housing 3 can be reduced.

従って、このようなコネクタ１では、端子７が多極化した場合に、ハウジング３とホルダ１１との挿入抵抗を２段階に分けることができ、端子７の多極化におけるハウジング３とホルダ１１との挿入抵抗を軽減でき、組付性を向上することができる。   Therefore, in such a connector 1, when the terminal 7 is multipolar, the insertion resistance between the housing 3 and the holder 11 can be divided into two stages, and the insertion resistance between the housing 3 and the holder 11 when the terminal 7 is multipolar is reduced. It can be reduced and the assemblability can be improved.

また、短い延設長さＬ２を有する押上部１３は、長い延設長さＬ１を有する押上部１３が接点部９を最大に変位させた後、接点部９の先端と当接して接点部９の変位を開始させるので、長い延設長さＬ１を有する押上部１３による接点部９の変位を終えた後に、短い延設長さＬ２を有する押上部１３によって接点部９を変位させることができ、複数の押上部１３による接点部９を変位させるタイミングを確実に分けることができる。   The push-up portion 13 having a short extension length L2 is brought into contact with the tip of the contact portion 9 after the push-up portion 13 having a long extension length L1 displaces the contact portion 9 to the maximum. Therefore, after the displacement of the contact portion 9 by the push-up portion 13 having the long extension length L1, the contact portion 9 can be displaced by the push-up portion 13 having the short extension length L2. And the timing which displaces the contact part 9 by the several pushing-up part 13 can be divided reliably.

さらに、押上部１３は、接点部９の先端との当接を開始させる部分が傾斜面１５で形成されているので、押上部１３による接点部９の変位をスムーズに行うことができ、さらに組付性を向上することができる。   Further, since the push-up portion 13 is formed with the inclined surface 15 at the portion where contact with the tip of the contact portion 9 is started, the displacement of the contact portion 9 by the push-up portion 13 can be smoothly performed. Adhesiveness can be improved.

なお、本発明の実施の形態に係るコネクタでは、複数の押上部の延設長さが２種類に設定されているが、これに限らず、延設長さを２種類以上設定してもよい。この場合には、延設長さが長い押上部が接点部を最大に変位させた後、延設長さが短い押上部が接点部の先端と当接して接点部の変位を開始させるように延設長さを設定することが好ましい。   In the connector according to the embodiment of the present invention, the extension lengths of the plurality of push-up portions are set to two types, but not limited to this, two or more types of extension lengths may be set. . In this case, after the push-up portion with the long extension length displaces the contact portion to the maximum, the push-up portion with the short extension length comes into contact with the tip of the contact portion to start the displacement of the contact portion. It is preferable to set the extended length.
