　例えば図７に示す状態から、第２インシュレータ３０が第１インシュレータ２０に対して相対的に前後左右方向に移動すると、コンタクト４０の第１弾性部４３は、第２インシュレータ３０の移動方向に沿って弾性変形する。コンタクト４０の第２支持部４４は、第２インシュレータ３０の前後左右方向への移動に伴う第１弾性部４３の弾性変形により、第２インシュレータ３０を所定位置に向けて付勢する。 For example, when the second insulator 30 moves in the front-back and left-right directions relative to the first insulator 20 from the state shown in FIG. 7, the first elastic portion 43 of the contact 40 moves along the moving direction of the second insulator 30. Elastically deforms. The second support portion 44 of the contact 40 urges the second insulator 30 toward a predetermined position by elastic deformation of the first elastic portion 43 accompanying the movement of the second insulator 30 in the front-rear and left-right directions.
　例えば図７に示す状態から、第２インシュレータ３０が第１インシュレータ２０に対して相対的に上方向に移動すると、コンタクト４０の第１弾性部４３は、第２インシュレータ３０の移動方向に沿って弾性変形する。コンタクト４０の第２支持部４４は、第２インシュレータ３０の上方向への移動に伴う第１弾性部４３の弾性変形により、第２インシュレータ３０を所定位置に向けて付勢する。 For example, when the second insulator 30 moves upward relative to the first insulator 20 from the state shown in FIG. 7, the first elastic portion 43 of the contact 40 is elastic along the moving direction of the second insulator 30. Deform. The second support portion 44 of the contact 40 urges the second insulator 30 toward a predetermined position by elastic deformation of the first elastic portion 43 accompanying the upward movement of the second insulator 30.
　例えば図８に示す状態から、第２インシュレータ３０が第１インシュレータ２０に対して相対的に下方向に移動すると、コンタクト４０の第１弾性部４３並びに第１金具５０の第１弾性部５４及び第２弾性部５５は、第２インシュレータ３０の移動方向に沿って弾性変形する。コンタクト４０の第２支持部４４及び第１金具５０の受け部５３は、第２インシュレータ３０の下方向への移動に伴う第１弾性部４３並びに第１弾性部５４及び第２弾性部５５の弾性変形により、第２インシュレータ３０を所定位置に向けて付勢する。 For example, when the second insulator 30 moves downward relative to the first insulator 20 from the state shown in FIG. 8, the first elastic portion 43 of the contact 40 and the first elastic portion 54 and the first elastic portion 54 of the first metal fitting 50 The two elastic portions 55 are elastically deformed along the moving direction of the second insulator 30. The second support portion 44 of the contact 40 and the receiving portion 53 of the first metal fitting 50 are elastic of the first elastic portion 43 and the first elastic portion 54 and the second elastic portion 55 due to the downward movement of the second insulator 30. Due to the deformation, the second insulator 30 is urged toward a predetermined position.
　第１インシュレータ２０の短手壁２２ａは、第１インシュレータ２０に対する第２インシュレータ３０の過剰な移動を規制する。より具体的には、例えば図８に示す状態から第２インシュレータ３０が大きく左右方向に移動すると、第２インシュレータ３０の短手壁３２ａと第１インシュレータ２０の短手壁２２ａとが互いに接触する。これにより、第２インシュレータ３０は、左右方向の外側にさらに移動しない。 The short wall 22a of the first insulator 20 regulates the excessive movement of the second insulator 30 with respect to the first insulator 20. More specifically, for example, when the second insulator 30 moves largely in the left-right direction from the state shown in FIG. 8, the short wall 32a of the second insulator 30 and the short wall 22a of the first insulator 20 come into contact with each other. As a result, the second insulator 30 does not move further outward in the left-right direction.
　第１インシュレータ２０の長手壁２２ｂは、第１インシュレータ２０に対する第２インシュレータ３０の過剰な移動を規制する。より具体的には、例えば図７に示す状態から第２インシュレータ３０が大きく前後方向に移動すると、第２インシュレータ３０の長手壁３２ｂと第１インシュレータ２０の長手壁２２ｂとが互いに接触する。これにより、第２インシュレータ３０は、前後方向の外側にさらに移動しない。 The longitudinal wall 22b of the first insulator 20 regulates the excessive movement of the second insulator 30 with respect to the first insulator 20. More specifically, for example, when the second insulator 30 moves significantly in the front-rear direction from the state shown in FIG. 7, the longitudinal wall 32b of the second insulator 30 and the longitudinal wall 22b of the first insulator 20 come into contact with each other. As a result, the second insulator 30 does not move further outward in the front-rear direction.
　第１インシュレータ２０の収容部２５は、第１インシュレータ２０に対する第２インシュレータ３０の過剰な移動を規制する。より具体的には、例えば図８に示す状態から第２インシュレータ３０が上方向に移動すると、第２インシュレータ３０の位置規制部３５と第１インシュレータ２０の収容部２５とが互いに接触する。例えば、位置規制部３５の被規制面３５ｂと収容部２５の規制面２５ａとが互いに接触する。これにより、第２インシュレータ３０は、上方向にさらに移動しない。 The accommodating portion 25 of the first insulator 20 regulates the excessive movement of the second insulator 30 with respect to the first insulator 20. More specifically, for example, when the second insulator 30 moves upward from the state shown in FIG. 8, the position regulating portion 35 of the second insulator 30 and the accommodating portion 25 of the first insulator 20 come into contact with each other. For example, the regulated surface 35b of the position regulating portion 35 and the regulating surface 25a of the accommodating portion 25 come into contact with each other. As a result, the second insulator 30 does not move further upward.
　第１金具５０の受け部５３は、第１インシュレータ２０に対する第２インシュレータ３０の過剰な移動を規制する。より具体的には、例えば図８に示す状態から第２インシュレータ３０が下方向に移動すると、第１金具５０の第１弾性部５４及び第２弾性部５５が弾性変形した状態で、第２インシュレータ３０の位置規制部３５と第１金具５０の受け部５３とが互いに接触する。これにより、第２インシュレータ３０は、下方向にさらに移動しない。 The receiving portion 53 of the first metal fitting 50 regulates the excessive movement of the second insulator 30 with respect to the first insulator 20. More specifically, for example, when the second insulator 30 moves downward from the state shown in FIG. 8, the second insulator is in a state where the first elastic portion 54 and the second elastic portion 55 of the first metal fitting 50 are elastically deformed. The position regulating portion 35 of 30 and the receiving portion 53 of the first metal fitting 50 come into contact with each other. As a result, the second insulator 30 does not move further downward.
　第１インシュレータ２０の長手壁２２ｂは、第１インシュレータ２０に対する第２インシュレータ３０の過剰な回転を規制する。より具体的には、例えば図７に示す状態から、左右方向から見た側面視において第２インシュレータ３０が大きく時計回り又は反時計回りに回転すると、第２インシュレータ３０の長手壁３２ｂと第１インシュレータ２０の長手壁２２ｂとが互いに接触する。これにより、第２インシュレータ３０は、左右方向から見た側面視における時計回り又は反時計回りにさらに回転しない。 The longitudinal wall 22b of the first insulator 20 regulates the excessive rotation of the second insulator 30 with respect to the first insulator 20. More specifically, for example, when the second insulator 30 rotates largely clockwise or counterclockwise in the side view seen from the left-right direction from the state shown in FIG. 7, the longitudinal wall 32b and the first insulator of the second insulator 30 The longitudinal walls 22b of 20 come into contact with each other. As a result, the second insulator 30 does not further rotate clockwise or counterclockwise when viewed from the left-right direction.
　図９は、接続対象物７０が接続されている状態の図７に対応する断面図である。図９を参照しながら、コネクタ１０に対して接続対象物７０を接続するときの、フローティング構造を有するコネクタ１０の動作について主に説明する。 FIG. 9 is a cross-sectional view corresponding to FIG. 7 in a state where the connection object 70 is connected. With reference to FIG. 9, the operation of the connector 10 having a floating structure when the connection object 70 is connected to the connector 10 will be mainly described.
　上記のようなフローティング構造を有するコネクタ１０に対して、接続対象物７０の前後位置及び左右位置を略一致させながら、互いを上下方向に対向させる。その後、第１インシュレータ２０の開口２１ａ及び第２インシュレータ３０の開口３１ａを通過させて接続対象物７０を下方に移動させる。このとき、互いの位置が例えば前後左右方向に多少ずれていても、第２インシュレータ３０の誘い込み面３６と接続対象物７０とが接触する。その結果、コネクタ１０のフローティング構造により第２インシュレータ３０が第１インシュレータ２０に対して相対的に移動する。これにより、接続対象物７０がコネクタ１０に誘い込まれる。 The connector 10 having the floating structure as described above is opposed to each other in the vertical direction while substantially matching the front-rear position and the left-right position of the connection object 70. After that, the connection object 70 is moved downward by passing through the opening 21a of the first insulator 20 and the opening 31a of the second insulator 30. At this time, even if the positions of the second insulator 30 are slightly deviated from each other in the front-back and left-right directions, the invitation surface 36 of the second insulator 30 and the object to be connected 70 come into contact with each other. As a result, the floating structure of the connector 10 causes the second insulator 30 to move relative to the first insulator 20. As a result, the object to be connected 70 is invited to the connector 10.
　接続対象物７０を下方にさらに移動させると、接続対象物７０の一部が第２インシュレータ３０の挿入部３３に挿入される。接続対象物７０は、回路基板ＣＢに対して直交する方向から所定の角度で傾斜している。このとき、コネクタ１０のコンタクト４０と接続対象物７０とが互いに接触する。より具体的には、コンタクト４０の接触部４６が接続対象物７０の信号線７１と接触する。このとき、コンタクト４０の第２弾性部４５は、後方に向けて若干弾性変形し、第１弾性部４３及び第２支持部４４との前後方向の間隔を狭める。同様に、第２インシュレータ３０の前側の長手壁３２ｂと接続対象物７０とが互いに接触する。 When the connection object 70 is further moved downward, a part of the connection object 70 is inserted into the insertion portion 33 of the second insulator 30. The connection object 70 is inclined at a predetermined angle from a direction orthogonal to the circuit board CB. At this time, the contact 40 of the connector 10 and the object to be connected 70 come into contact with each other. More specifically, the contact portion 46 of the contact 40 comes into contact with the signal line 71 of the connection object 70. At this time, the second elastic portion 45 of the contact 40 is slightly elastically deformed toward the rear, narrowing the distance between the first elastic portion 43 and the second support portion 44 in the front-rear direction. Similarly, the longitudinal wall 32b on the front side of the second insulator 30 and the object to be connected 70 come into contact with each other.
　以上により、コネクタ１０と接続対象物７０とは、完全に接続される。このとき、コンタクト４０及び信号線７１を介して、回路基板ＣＢとモジュールとが電気的に接続される。 From the above, the connector 10 and the connection object 70 are completely connected. At this time, the circuit board CB and the module are electrically connected via the contact 40 and the signal line 71.
　この状態で、コンタクト４０の接触部４６と第２インシュレータ３０の前側の長手壁３２ｂとは、コンタクト４０の第２弾性部４５による前後方向に沿った外側への弾性力により接続対象物７０を前後両側から挟持する。これにより生じる、接続対象物７０への押圧力の反作用により、接続対象物７０をコネクタ１０から抜去する場合、第２インシュレータ３０は、コンタクト４０を介して抜去方向、すなわち上方向への力を受ける。 In this state, the contact portion 46 of the contact 40 and the longitudinal wall 32b on the front side of the second insulator 30 move the connection object 70 back and forth by the elastic force outward along the front-rear direction by the second elastic portion 45 of the contact 40. Hold from both sides. When the connection object 70 is removed from the connector 10 due to the reaction of the pressing force on the connection object 70, the second insulator 30 receives a force in the removal direction, that is, in the upward direction via the contact 40. ..
　これにより、仮に第２インシュレータ３０が上方向に移動したとしても、図８に示す第１インシュレータ２０の収容部２５が、第２インシュレータ３０の第１インシュレータ２０からの上方への抜けを抑制する。より具体的には、収容部２５の規制面２５ａは、第２インシュレータ３０の位置規制部３５の被規制面３５ｂの直上に位置している。規制面２５ａと被規制面３５ｂとは、互いに上下方向に対向している。したがって、第２インシュレータ３０が上方に移動しようとすると、被規制面３５ｂが規制面２５ａと接触する。これにより、第２インシュレータ３０は、上方にさらに移動しない。 As a result, even if the second insulator 30 moves upward, the accommodating portion 25 of the first insulator 20 shown in FIG. 8 suppresses the second insulator 30 from coming out of the first insulator 20 upward. More specifically, the regulation surface 25a of the accommodating portion 25 is located directly above the regulated surface 35b of the position regulation portion 35 of the second insulator 30. The regulated surface 25a and the regulated surface 35b face each other in the vertical direction. Therefore, when the second insulator 30 tries to move upward, the regulated surface 35b comes into contact with the regulating surface 25a. As a result, the second insulator 30 does not move further upward.
　以上のような一実施形態に係るコネクタ１０によれば、接続対象物７０の挿入に伴うコネクタ１０の破損を抑制可能である。より具体的には、第１金具５０が受け部５３及び第１弾性部５４を有することで、接続対象物７０をコネクタ１０に挿入するときの力が強いときであっても、第１金具５０の第１弾性部５４が接続対象物７０の挿入に伴う衝撃を吸収可能である。したがって、第１金具５０は、接続対象物７０の挿入に伴う第２インシュレータ３０、より具体的には位置規制部３５の破損を抑制可能である。加えて、第１金具５０は、接続対象物７０の挿入に伴う衝撃によって第２インシュレータ３０が大きく沈み込み、回路基板ＣＢと接触することを抑制可能である。これにより、第２インシュレータ３０及び回路基板ＣＢの破損が抑制可能である。加えて、第１金具５０は、接続対象物７０の挿入に伴う衝撃によって第２インシュレータ３０が大きく沈みこむことを抑制可能であるので、コンタクト４０の変形及び破損を抑制することもできる。 According to the connector 10 according to the above embodiment, it is possible to suppress damage to the connector 10 due to insertion of the connection object 70. More specifically, since the first metal fitting 50 has the receiving portion 53 and the first elastic portion 54, even when the force when inserting the connection object 70 into the connector 10 is strong, the first metal fitting 50 The first elastic portion 54 of the above can absorb the impact caused by the insertion of the connection object 70. Therefore, the first metal fitting 50 can suppress damage to the second insulator 30, more specifically, the position regulating portion 35 due to the insertion of the connection object 70. In addition, the first metal fitting 50 can prevent the second insulator 30 from sinking significantly due to the impact caused by the insertion of the object to be connected 70 and coming into contact with the circuit board CB. As a result, damage to the second insulator 30 and the circuit board CB can be suppressed. In addition, since the first metal fitting 50 can suppress the second insulator 30 from being greatly sunk due to the impact caused by the insertion of the connection object 70, it is also possible to suppress the deformation and breakage of the contact 40.
　第１金具５０の受け部５３によって支持されている第２インシュレータ３０の回転軸の被支持面が曲面であることで、第１インシュレータ２０に対する第２インシュレータ３０の回転運動が滑らかに行われる。加えて、回転軸から受け部５３に力が加わりやすくなるため、第１金具５０が弾性変形しやすくなる。以上により、接続対象物７０の挿入に伴う第２インシュレータ３０、より具体的には位置規制部３５の破損が抑制可能である。 Since the supported surface of the rotation shaft of the second insulator 30 supported by the receiving portion 53 of the first metal fitting 50 is a curved surface, the rotational movement of the second insulator 30 with respect to the first insulator 20 is smoothly performed. In addition, since a force is easily applied from the rotating shaft to the receiving portion 53, the first metal fitting 50 is easily elastically deformed. As described above, it is possible to suppress damage to the second insulator 30, more specifically, the position regulating portion 35 due to the insertion of the object to be connected 70.
　第１金具５０の受け部５３によって支持されている第２インシュレータ３０の回転軸の被支持面の曲率半径が一定であることで、第１インシュレータ２０に対する第２インシュレータ３０の回転運動がより滑らかに行われる。加えて、回転軸から受け部５３に力がより加わりやすくなるため、第１金具５０がより弾性変形しやすくなる。以上により、接続対象物７０の挿入に伴う第２インシュレータ３０、より具体的には位置規制部３５の破損がさらに抑制可能である。 Since the radius of curvature of the supported surface of the rotation axis of the second insulator 30 supported by the receiving portion 53 of the first metal fitting 50 is constant, the rotational movement of the second insulator 30 with respect to the first insulator 20 becomes smoother. Will be done. In addition, since a force is more likely to be applied from the rotating shaft to the receiving portion 53, the first metal fitting 50 is more likely to be elastically deformed. As described above, damage to the second insulator 30, more specifically, the position regulating portion 35 due to the insertion of the object to be connected 70 can be further suppressed.
　第１金具５０が異なる位置に形成されている一対の第１弾性部５４を有することで、第１金具５０が弾性変形するときの形状バランスが安定する。したがって、接続対象物７０の挿入に伴う第２インシュレータ３０、より具体的には位置規制部３５の破損がさらに抑制可能である。 By having the pair of first elastic portions 54 formed at different positions of the first metal fitting 50, the shape balance when the first metal fitting 50 is elastically deformed is stable. Therefore, damage to the second insulator 30, more specifically, the position regulating portion 35 due to the insertion of the connection object 70 can be further suppressed.
　第１金具５０が第１弾性部５４と連結している第２弾性部５５を有することで、第１金具５０の弾性変形がより容易になる。したがって、第１金具５０が接続対象物７０の挿入に伴う衝撃をより効果的に吸収可能であるので、接続対象物７０の挿入に伴う第２インシュレータ３０、より具体的には位置規制部３５の破損がより効果的に抑制可能である。 By having the second elastic portion 55 in which the first metal fitting 50 is connected to the first elastic portion 54, the elastic deformation of the first metal fitting 50 becomes easier. Therefore, since the first metal fitting 50 can more effectively absorb the impact caused by the insertion of the connecting object 70, the second insulator 30 accompanying the insertion of the connecting object 70, more specifically, the position regulating unit 35 Damage can be suppressed more effectively.
　第１金具５０が異なる位置に形成されている一対の第２弾性部５５を有することで、第１金具５０が弾性変形するときの形状バランスが安定する。したがって、接続対象物７０の挿入に伴う第２インシュレータ３０、より具体的には位置規制部３５の破損がさらに抑制可能である。 By having the pair of second elastic portions 55 formed at different positions of the first metal fitting 50, the shape balance when the first metal fitting 50 is elastically deformed is stable. Therefore, damage to the second insulator 30, more specifically, the position regulating portion 35 due to the insertion of the connection object 70 can be further suppressed.
　受け部５３、第１弾性部５４、及び第２弾性部５５の全体形状がコ字状となるように形成されていることで、第１弾性部５４及び第２弾性部５５の弾性変形が容易となる。したがって、第１金具５０が接続対象物７０の挿入に伴う衝撃をより効果的に吸収可能であるので、接続対象物７０の挿入に伴う第２インシュレータ３０、より具体的には位置規制部３５の破損がより効果的に抑制可能である。 Since the receiving portion 53, the first elastic portion 54, and the second elastic portion 55 are formed so as to have a U-shape as a whole, the first elastic portion 54 and the second elastic portion 55 can be easily elastically deformed. It becomes. Therefore, since the first metal fitting 50 can more effectively absorb the impact caused by the insertion of the connecting object 70, the second insulator 30 accompanying the insertion of the connecting object 70, more specifically, the position regulating unit 35 Damage can be suppressed more effectively.
　第２弾性部５５が受け部５３よりも回路基板ＣＢ側に位置することで、受け部５３が上方から受けた力を第１弾性部５４と共に第２弾性部５５による弾性変形によって下方から受け止めることが可能となる。したがって、第１金具５０が接続対象物７０の上方からの挿入に伴う衝撃をより効果的に吸収可能である。 Since the second elastic portion 55 is located closer to the circuit board CB than the receiving portion 53, the force received by the receiving portion 53 from above is received from below by the elastic deformation by the second elastic portion 55 together with the first elastic portion 54. Is possible. Therefore, the first metal fitting 50 can more effectively absorb the impact caused by the insertion of the connection object 70 from above.
　第１金具５０において、第２弾性部５５が実装部５７よりも回路基板ＣＢの反対側に位置し、かつ、回路基板ＣＢと間隔を空けて配置されていることで、第２弾性部５５が弾性変形したときであっても、第２弾性部５５と回路基板ＣＢとの間の接触が抑制可能である。したがって、第２インシュレータ３０及び回路基板ＣＢの破損が抑制可能である。加えて、回路基板ＣＢと第２弾性部５５との間の空間により、第２弾性部５５が弾性変形したときの弾性変形量が十分に得られる。 In the first metal fitting 50, the second elastic portion 55 is located on the opposite side of the circuit board CB from the mounting portion 57, and is arranged at a distance from the circuit board CB, so that the second elastic portion 55 is arranged. Even when elastically deformed, the contact between the second elastic portion 55 and the circuit board CB can be suppressed. Therefore, damage to the second insulator 30 and the circuit board CB can be suppressed. In addition, the space between the circuit board CB and the second elastic portion 55 provides a sufficient amount of elastic deformation when the second elastic portion 55 is elastically deformed.
　第１金具５０が受け部５３から連続しながら回路基板ＣＢ側に向けて屈曲する先端部５６を有することで、例えば第２インシュレータ３０が左右方向に沿って移動したときであっても、第１金具５０における第２インシュレータ３０側の先端による第２インシュレータ３０の削れが抑制可能である。したがって、第２インシュレータ３０の破損が抑制可能である。 Since the first metal fitting 50 has a tip portion 56 that bends toward the circuit board CB side while being continuous from the receiving portion 53, for example, even when the second insulator 30 moves along the left-right direction, the first It is possible to suppress scraping of the second insulator 30 by the tip of the metal fitting 50 on the side of the second insulator 30. Therefore, damage to the second insulator 30 can be suppressed.
　コンタクト４０が弾性係数の小さい金属材料によって形成されていることで、コネクタ１０は、第２インシュレータ３０にかかる力が小さい場合であっても、必要とされる第２インシュレータ３０の移動量を確保できる。第２インシュレータ３０は、第１インシュレータ２０に対して滑らかに移動することができる。これにより、コネクタ１０は、接続対象物７０とコネクタ１０との間の位置ずれを容易に吸収できる。コネクタ１０では、何らかの外的要因によって発生する振動をコンタクト４０の第１弾性部４３が吸収する。これにより、実装部４２に大きな力が加わることがないので、コネクタ１０は、回路基板ＣＢとの接続部分が破損することを抑制できる。したがって、コネクタ１０は、接続対象物７０と接続されている状態であっても、接続信頼性を維持することができる。 Since the contact 40 is made of a metal material having a small elastic modulus, the connector 10 can secure the required movement amount of the second insulator 30 even when the force applied to the second insulator 30 is small. .. The second insulator 30 can move smoothly with respect to the first insulator 20. As a result, the connector 10 can easily absorb the misalignment between the connection object 70 and the connector 10. In the connector 10, the first elastic portion 43 of the contact 40 absorbs the vibration generated by some external factor. As a result, a large force is not applied to the mounting portion 42, so that the connector 10 can prevent the connection portion with the circuit board CB from being damaged. Therefore, the connector 10 can maintain the connection reliability even when it is connected to the connection object 70.
　第１金具５０及び第２金具６０が第１インシュレータ２０に圧入されて、実装部５７及び実装部６３が回路基板ＣＢにそれぞれはんだ付けされることで、第１金具５０及び第２金具６０は、第１インシュレータ２０を回路基板ＣＢに対して安定して固定できる。第１金具５０及び第２金具６０により、回路基板ＣＢに対する第１インシュレータ２０の実装強度が向上する。 The first metal fitting 50 and the second metal fitting 60 are press-fitted into the first insulator 20, and the mounting portion 57 and the mounting portion 63 are soldered to the circuit board CB, respectively. The first insulator 20 can be stably fixed to the circuit board CB. The first metal fitting 50 and the second metal fitting 60 improve the mounting strength of the first insulator 20 on the circuit board CB.

　例えば、第１金具５０の受け部５３によって支持されている回転軸の被支持面は、曲面でなく、平面等の任意の形状の面であってもよい。 For example, the supported surface of the rotating shaft supported by the receiving portion 53 of the first metal fitting 50 may be a surface having an arbitrary shape such as a flat surface instead of a curved surface.
　例えば、第２インシュレータ３０は、位置規制部３５が回転軸を含まず、第１インシュレータ２０に対して回転しないように形成されていてもよい。 For example, the second insulator 30 may be formed so that the position regulating unit 35 does not include the rotation axis and does not rotate with respect to the first insulator 20.
　例えば、第１金具５０の受け部５３によって支持されている回転軸の被支持面の曲率半径は一定でなくてもよい。 For example, the radius of curvature of the supported surface of the rotating shaft supported by the receiving portion 53 of the first metal fitting 50 does not have to be constant.
　例えば、上述した第１金具５０の機能を実現可能であれば、第２弾性部５５は、受け部５３よりも回路基板ＣＢと反対側に位置してもよい。 For example, if the function of the first metal fitting 50 described above can be realized, the second elastic portion 55 may be located on the side opposite to the circuit board CB with respect to the receiving portion 53.

　図１６は、第７変形例に係る第１金具５０単体を上面視で示した外観斜視図である。第１金具５０は、図６Ａ及び図６Ｂに示すような形状に代えて、図１６に示すような形状で形成されていてもよい。第７変形例では、第１金具５０は、上述した構成部に加えて、規制部５８を有してもよい。規制部５８は、受け部５３の前後両端において第１弾性部５４と反対側の縁部から屈曲しながら回路基板ＣＢ側に向けて延出してもよい。規制部５８は、第１弾性部５４が弾性変形したときに受け部５３が斜め下方に傾いて、第２弾性部５５の上面に接触してもよい。これにより、規制部５８は、第１弾性部５４の弾性変形に伴う受け部５３の過剰な変位を抑制可能である。 FIG. 16 is an external perspective view showing the first metal fitting 50 unit according to the seventh modification in a top view.

In the regulating portion 58, when the first elastic portion 54 is elastically deformed, the receiving portion 53 may be tilted obliquely downward and may come into contact with the upper surface of the second elastic portion 55. As a result, the regulating portion 58 can suppress excessive displacement of the receiving portion 53 due to elastic deformation of the first elastic portion 54.
　コンタクト４０は、弾性係数の小さい金属材料によって形成されているとして説明したが、これに限定されない。コンタクト４０は、必要とされる弾性変形量を確保できるのであれば、任意の弾性係数を有する金属材料によって形成されていてもよい。 The contact 40 has been described as being formed of a metal material having a small elastic modulus, but the contact 40 is not limited to this. The contact 40 may be formed of a metal material having an arbitrary elastic modulus as long as the required amount of elastic deformation can be secured.
　以上のようなコネクタ１０は、電子機器に搭載される。電子機器は、例えば、カメラ、レーダ、ドライブレコーダ、又はエンジンコントロールユニット等の任意の車載機器を含む。電子機器は、例えば、カーナビゲーションシステム、先進運転支援システム、又はセキュリティシステム等の車載システムにおいて使用される任意の車載機器を含む。電子機器は、例えば、パーソナルコンピュータ、コピー機、プリンタ、ファクシミリ、又は複合機等の任意の情報機器を含む。その他、電子機器は、任意の産業機器を含む。 The connector 10 as described above is mounted on an electronic device. Electronic devices include, for example, any in-vehicle device such as a camera, radar, drive recorder, or engine control unit. Electronic devices include any in-vehicle device used in in-vehicle systems such as car navigation systems, advanced driver assistance systems, or security systems. Electronic devices include any information device such as, for example, personal computers, copiers, printers, facsimiles, or multifunction devices. Other electronic devices include any industrial device.
　このような電子機器では、接続対象物７０の挿入に伴うコネクタ１０の破損を抑制可能であるので、電子機器の組み立て作業における作業性及び電子機器の製品としての信頼性が向上する。加えて、コネクタ１０の良好なフローティング構造により、コネクタ１０と接続対象物７０との位置ずれが吸収されるので、電子機器の組み立て作業における作業性が向上する。以上により、電子機器の製造が容易になる。コネクタ１０により回路基板ＣＢとの接続部分の破損が抑制されるので、電子機器の製品としての信頼性がさらに向上する。 In such an electronic device, damage to the connector 10 due to insertion of the connection object 70 can be suppressed, so that workability in the assembly work of the electronic device and reliability as a product of the electronic device are improved. In addition, the good floating structure of the connector 10 absorbs the misalignment between the connector 10 and the object to be connected 70, so that the workability in the assembly work of the electronic device is improved. As described above, the manufacture of electronic devices becomes easy. Since the connector 10 suppresses damage to the connection portion with the circuit board CB, the reliability of the electronic device as a product is further improved.
