Description

本発明は、カードエッジコネクタに関するものである。   The present invention relates to a card edge connector.

従来、特許文献１，２に示されるように、カードエッジコネクタが知られている。このカードエッジコネクタでは、回路基板そのものがオス端子の役割を果たし、その回路基板の端部をカードエッジコネクタに挿入することにより、回路基板の端部表面に設けられた複数の電極と、ハウジングから露出する端子の接触部とが接触して電気的な導通が図られる。   Conventionally, as shown in Patent Documents 1 and 2, card edge connectors are known. In this card edge connector, the circuit board itself serves as a male terminal, and by inserting the end of the circuit board into the card edge connector, a plurality of electrodes provided on the end surface of the circuit board and the housing Electrical contact is made with the exposed contact portion of the terminal.

特開２００３−１７８８３４号公報JP 2003-178834 A 特開２００９−１７６６２５号公報JP 2009-176625 A

これら従来のカードエッジコネクタでは、カードエッジコネクタを構成する端子の、弾性変形による反力、所謂付勢力により、回路基板の端部を固定する（保持する）構造となっている。   These conventional card edge connectors have a structure in which the end of the circuit board is fixed (held) by a reaction force caused by elastic deformation of the terminals constituting the card edge connector, a so-called urging force.

ところで、カードエッジコネクタでは、上記したように端子の接触部が回路基板の電極に接触することで電気的な導通が図られるため、端子と電極との接触圧を一定に保持できることが好ましい。しかしながら、ハウジングなどに外力が印加され、ハウジングと回路基板とが相対的に振動すると、上記した接触圧が不安定となる。従来は、回路基板に対する端子のばね力を高く設定することで、接触圧の変動を抑制していた。したがって、カードエッジコネクタに対して回路基板を挿抜する際に、端子と電極との物理的な接触による抵抗（例えば挿入時の挿入抵抗）が大きく、端子表面や電極表面のメッキ層が剥がれるなど端子や電極が損傷したり変形したりする恐れがあった。すなわち、電気的な接続信頼性が劣化する恐れがあった。   By the way, in the card edge connector, as described above, the contact portion of the terminal comes into contact with the electrode of the circuit board to achieve electrical conduction. Therefore, it is preferable that the contact pressure between the terminal and the electrode can be kept constant. However, when an external force is applied to the housing or the like and the housing and the circuit board vibrate relatively, the contact pressure described above becomes unstable. Conventionally, the fluctuation of the contact pressure is suppressed by setting the spring force of the terminal with respect to the circuit board high. Therefore, when a circuit board is inserted into or removed from a card edge connector, the resistance due to physical contact between the terminal and the electrode (for example, insertion resistance during insertion) is large, and the terminal surface and the plating layer on the electrode surface are peeled off. There was a risk of damage or deformation of the electrode. That is, the electrical connection reliability may be deteriorated.

本発明は上記問題点に鑑み、端子と電極との接触圧の変動を抑制でき、且つ、回路基板との電気的な接続信頼性を確保できるカードエッジコネクタを提供することを目的とする。   In view of the above problems, an object of the present invention is to provide a card edge connector that can suppress a change in contact pressure between a terminal and an electrode and can ensure electrical connection reliability with a circuit board.

上記目的を達成する為に請求項１に記載のカードエッジコネクタは、回路基板の端部が挿入配置される溝部を有するハウジングと、ハウジングに保持され、回路基板の電極とハーネスとを電気的に接続する部材であって、電極と接触すべく溝部の側壁から回路基板が配置される空間に露出された接触部を有し、該接触部が溝部の深さ方向及び回路基板の厚さ方向に対応する溝部の幅方向の両方向に垂直な方向に沿って配列された複数の端子と、ハウジングに設けられた軸部と、軸部に取り付けられたばね部材と、を備えている。   In order to achieve the above object, a card edge connector according to claim 1 is a housing having a groove portion into which an end portion of a circuit board is inserted, and is held by the housing to electrically connect an electrode and a harness of the circuit board. A connecting member having a contact portion exposed in a space in which the circuit board is disposed from the side wall of the groove portion to be in contact with the electrode, the contact portion being in the depth direction of the groove portion and the thickness direction of the circuit board. A plurality of terminals arranged along a direction perpendicular to both the widthwise directions of the corresponding groove portions, a shaft portion provided in the housing, and a spring member attached to the shaft portion are provided.

軸部は、配列方向において、複数の端子の接触部が間に位置するように複数の接触部の両端側であって、溝部に対し幅方向における同一側にそれぞれ設けられている。   The shaft portions are provided at both ends of the plurality of contact portions so that the contact portions of the plurality of terminals are located in the arrangement direction, and are respectively provided on the same side in the width direction with respect to the groove portion.

ばね部材は、軸部に対し、軸部周りに回動可能に取り付けられた回動部と、該回動部から延びた第１脚部及び第２脚部とを有している。そして、第１脚部及び第２脚部の両方が回路基板における軸部側の一面に接触して回路基板を固定する固定状態で、深さ方向において、第１脚部の固定部と第２脚部の固定部との間に軸部の中心が位置し、回路基板を挿入する際に、回路基板がばね部材の第１脚部に接触すると、第１脚部の固定部が回路基板における軸部側の一面上に位置するように回動部が一方向に回転し、回路基板がばね部材の第２脚部に接触すると、第２脚部の固定部が回路基板における軸部側の一面上に位置するように回動部が一方向と反対に回転するとともに、第１脚部及び第２脚部の両方が回路基板における軸部側の一面に接触して付勢力を与え、回路基板を固定するように構成されていることを特徴とする。   The spring member has a rotating portion attached to the shaft portion so as to be rotatable around the shaft portion, and a first leg portion and a second leg portion extending from the rotating portion. Then, both the first leg portion and the second leg portion are in a fixed state in which the circuit board is fixed by contacting one surface of the circuit board on the shaft portion side, and in the depth direction, the first leg fixing portion and the second leg portion are fixed. When the center of the shaft portion is located between the fixed portion of the leg portion and the circuit board contacts the first leg portion of the spring member when the circuit board is inserted, the fixed portion of the first leg portion is in the circuit board. When the rotating part rotates in one direction so as to be positioned on one surface of the shaft part side and the circuit board contacts the second leg part of the spring member, the fixing part of the second leg part is on the shaft part side of the circuit board. The rotating part rotates opposite to one direction so as to be located on one surface, and both the first leg part and the second leg part contact one surface of the shaft part side of the circuit board to give a biasing force. The substrate is configured to be fixed.

このように、ハウジングに軸部が設けられ、軸部に回路基板を固定するためのばね部材が取り付けられる。ばね部材は、軸部周りに回動可能とされた回動部と、回動部から延びる２本の脚部（第１脚部及び第２脚部）を有しており、回路基板の挿入方向（深さ方向のうち、溝部の開口から底に向かう方向）において、第１脚部の固定部が入口側、第２脚部の固定部が奥側に位置する。   Thus, the shaft portion is provided in the housing, and the spring member for fixing the circuit board is attached to the shaft portion. The spring member has a rotating portion that is rotatable around the shaft portion, and two legs (first and second legs) extending from the rotating portion, and inserting a circuit board In the direction (in the depth direction, the direction from the opening of the groove portion toward the bottom), the fixing portion of the first leg portion is located on the inlet side, and the fixing portion of the second leg portion is located on the back side.

本発明では、回路基板の挿入時において、回路基板が第１脚部に接触しても、第１脚部の固定部が回路基板の軸部側一面上に位置すべく回動部が一方向に回転するように、ばね部材が構成される。第１脚部は、回路基板と接触することで受ける挿入方向の力を、回動部を一方向に回転させる力に変換し、これにより回動部が回転する。したがって、第１脚部のみ回路基板に接触した時点では付勢力を付与しない。これにより、回路基板を奥側（溝部の底側）へスムースに挿入することができる。なお、軸部への取り付け状態によって回路基板が第１脚部に接触しない場合には、第１脚部による抵抗が生じないため、回路基板を奥側へスムースに挿入することができる。   In the present invention, when the circuit board is inserted, even if the circuit board comes into contact with the first leg part, the rotating part is in one direction so that the fixing part of the first leg part is located on the one surface side of the circuit board. The spring member is configured to rotate in the direction. The first leg converts the force in the insertion direction received by contacting the circuit board into a force that rotates the rotating part in one direction, whereby the rotating part rotates. Therefore, no biasing force is applied when only the first leg contacts the circuit board. Thereby, a circuit board can be smoothly inserted into the back side (bottom side of a groove part). In addition, when the circuit board does not contact the first leg portion due to the attachment state to the shaft portion, no resistance is generated by the first leg portion, so that the circuit board can be smoothly inserted to the back side.

また、回路基板がばね部材の第２脚部に接触すると、第２脚部の固定部が回路基板の軸部側一面上に位置すべく回動部が一方向と反対に回転するように、ばね部材が構成されている。さらに、この反対方向への回転により、第１脚部及び第２脚部が弾性変形しつつ第１脚部の固定部及び第２脚部の固定部の両方が回路基板の軸部側一面に接触し、これにより回路基板に付勢力を与えるようにばね部材が構成されている。   Further, when the circuit board comes into contact with the second leg portion of the spring member, the rotating portion rotates in the opposite direction to one direction so that the fixing portion of the second leg portion is positioned on the one surface side of the circuit board. A spring member is configured. Further, by the rotation in the opposite direction, the first leg portion and the second leg portion are elastically deformed, and both the fixing portion of the first leg portion and the fixing portion of the second leg portion are on one surface side of the circuit board. The spring member is configured to contact and thereby apply a biasing force to the circuit board.

このように、本発明では、２本の脚部が回路基板に接触した状態で、ばね部材の付勢力により回路基板を固定することができる。このばね部材は、複数の接触部の両端側にそれぞれ設けられているため、配列方向において回路基板を安定的に固定することができる。また、第１脚部の固定部及び第２脚部の固定部は、深さ方向において異なる位置で回路基板に接触するので、深さ方向においても回路基板を安定的に固定することができる。したがって、端子と電極との接触圧の変動を抑制することができる。   Thus, in this invention, a circuit board can be fixed with the urging | biasing force of a spring member in the state which two leg parts contacted the circuit board. Since the spring members are respectively provided on both end sides of the plurality of contact portions, the circuit board can be stably fixed in the arrangement direction. Moreover, since the fixing part of the first leg and the fixing part of the second leg contact the circuit board at different positions in the depth direction, the circuit board can be stably fixed also in the depth direction. Therefore, fluctuations in the contact pressure between the terminal and the electrode can be suppressed.

また、ばね部材によって端子と電極との接触圧の変動を抑制することができるため、回路基板に対する端子のばね力を従来よりも小さく設定することができる。そして、これにより、回路基板の挿抜にともなうメッキ層の剥がれなど端子や電極の損傷・変形を抑制することができる。すなわち、端子と電極との接触圧の変動を抑制でき、且つ、回路基板との電気的な接続信頼性を確保することができる。特に本発明では、ハウジングに軸部を設け、該軸部にばね部材を取り付けるという簡素な構成で、上記効果を奏することができる。   In addition, since the fluctuation of the contact pressure between the terminal and the electrode can be suppressed by the spring member, the spring force of the terminal with respect to the circuit board can be set smaller than the conventional one. Thereby, it is possible to suppress damage and deformation of the terminals and electrodes such as peeling of the plating layer accompanying insertion / extraction of the circuit board. That is, fluctuations in contact pressure between the terminal and the electrode can be suppressed, and electrical connection reliability with the circuit board can be ensured. In particular, in the present invention, the above effect can be obtained with a simple configuration in which a shaft portion is provided in the housing and a spring member is attached to the shaft portion.

また、本発明では、回路基板が入口側の第１脚部に接触しても付勢力を生じず、奥側の第２脚部に接触して付勢力を生じるようになっている。したがって、深さ方向において複数個所で回路基板を固定する構成でありながら、回路基板をハウジングの溝部奥側まで容易に挿入することができる。   In the present invention, no urging force is generated even when the circuit board contacts the first leg portion on the inlet side, and an urging force is generated by contacting the second leg portion on the back side. Therefore, the circuit board can be easily inserted to the back side of the groove portion of the housing while the circuit board is fixed at a plurality of positions in the depth direction.

請求項２に記載のように、第１脚部及び第２脚部は、回路基板が挿入されない初期状態での固定部から軸部までの幅方向の距離が、回路基板の固定状態での固定部から軸部までの距離よりも長く、第１脚部は、回動部との連結端から固定部までが連結端に近いほど深さ方向において軸部に近い傾斜を有するとともに、固定部から先端までが先端に近いほど幅方向おいて固定部から離れる傾斜を有する構成が好ましい。   According to a second aspect of the present invention, the first leg portion and the second leg portion are fixed in a fixed state in which the circuit board is fixed in the width direction distance from the fixing portion to the shaft portion in the initial state where the circuit board is not inserted. The first leg portion has a slope closer to the shaft portion in the depth direction as the distance from the connecting end to the rotating portion to the fixing portion is closer to the connecting end than the distance from the shaft portion to the shaft portion. A configuration having an inclination away from the fixed portion in the width direction as the tip is closer to the tip is preferable.

このような構成では、第１脚部は回路基板から挿入方向の力を受けると、第１脚部における固定部から連結端までの傾斜部分を介して回動部に上記力が伝達される。この時点で、第２脚部は変位可能な自由端状態にある。したがって、回動部は、第１脚部の固定部が回路基板の軸部側一面上に位置するように一方向に回転する。このように、第１脚部の上記傾斜部分にて、回路基板の挿入方向の力を、回動部を一方向に回転させる力に変換することができる。そして、回動部の回転により、第１脚部の固定部が深さ方向において回路基板の軸部側一面上に位置するように変位する。したがって、第１脚部に回路基板が接触しても、第１脚部により付勢力を付与せずに回路基板を奥側へスムースに挿入することができる。   In such a configuration, when the first leg portion receives a force in the insertion direction from the circuit board, the force is transmitted to the rotating portion via the inclined portion from the fixed portion to the connecting end of the first leg portion. At this point, the second leg is in a displaceable free end state. Therefore, the rotating portion rotates in one direction so that the fixing portion of the first leg portion is located on the one surface side of the circuit board. As described above, the force in the insertion direction of the circuit board can be converted into the force for rotating the rotating portion in one direction at the inclined portion of the first leg portion. Then, due to the rotation of the rotating portion, the fixed portion of the first leg portion is displaced so as to be positioned on the entire surface on the shaft portion side of the circuit board in the depth direction. Therefore, even if the circuit board comes into contact with the first leg, the circuit board can be smoothly inserted to the back without applying a biasing force by the first leg.

また、第１脚部及び第２脚部はそれぞれ、初期状態での固定部から軸部までの幅方向の距離が、固定状態での固定部から軸部までの距離よりも長くなっている。したがって、第１脚部の固定部及び第２脚部の固定部がともに回路基板の軸部側一面に接触した状態で、回路基板に付勢力を与えることができる。   The first leg portion and the second leg portion each have a longer distance in the width direction from the fixed portion to the shaft portion in the initial state than the distance from the fixed portion to the shaft portion in the fixed state. Therefore, it is possible to apply a biasing force to the circuit board in a state where both the fixing part of the first leg part and the fixing part of the second leg part are in contact with the one surface of the circuit board.

請求項３に記載のように、第２脚部は、回動部との連結端から固定部までが連結端に近いほど深さ方向において軸部に近い傾斜を有するとともに、固定部を曲げ部位として固定部よりも先端側の部位が幅方向において対応する軸部に近い構成としても良い。これによれば、回路基板の挿抜時における回路基板と第２脚部との物理的な接触による抵抗を小さくすることができる。   According to a third aspect of the present invention, the second leg portion has an inclination closer to the shaft portion in the depth direction as the distance from the connecting end to the rotating portion to the fixing portion is closer to the connecting end, and the fixing portion is bent at the site. As a configuration, a portion closer to the distal end than the fixed portion may be close to the corresponding shaft portion in the width direction. According to this, resistance due to physical contact between the circuit board and the second leg when the circuit board is inserted and removed can be reduced.

請求項４に記載のように、軸部は、複数の接触部の両端側それぞれにおいて、幅方向で溝が間に位置するように少なくとも一対設けられ、回路基板を挿入する際に、対をなすばね部材における第１脚部及び第２脚部の４つの脚部全てが回路基板に接触すると、４つの脚部により回路基板の両面側から付勢力を与えて回路基板を固定する構成が好ましい。   According to a fourth aspect of the present invention, at least a pair of shaft portions are provided so that the grooves are positioned in the width direction on each of both end sides of the plurality of contact portions, and a pair is formed when the circuit board is inserted. When all four legs of the first leg portion and the second leg portion of the spring member come into contact with the circuit board, it is preferable to apply a biasing force from both sides of the circuit board by the four legs to fix the circuit board.

回路基板の両面側にそれぞれ位置するばね部材によって回路基板を固定するので、回路基板の一面側に位置するばね部材と、回路基板の他方の面側に位置し、付勢力を付与しない支持部とで回路基板を固定する構成に比べて、幅方向における回路基板の位置調整代を大きくすることができる。例えば、反りの大きい回路基板にも対応することができる。また、反りなどにより、回路基板に過大な付勢力が付与されるのを抑制することもできる。   Since the circuit board is fixed by spring members located on both sides of the circuit board, a spring member located on one side of the circuit board, and a support part that is located on the other side of the circuit board and does not apply a biasing force, Thus, the circuit board position adjustment margin in the width direction can be increased as compared with the configuration in which the circuit board is fixed. For example, it is possible to cope with a circuit board having a large warp. Further, it is possible to suppress an excessive urging force from being applied to the circuit board due to warpage or the like.

請求項５に記載のように、幅方向で対をなすばね部材において、回路基板を固定する第１脚部の固定部同士が深さ方向で同じ位置とされ、回路基板を固定する第２脚部の固定部同士が深さ方向で同じ位置とされた構成とすると良い。   The second leg for fixing the circuit board by fixing the fixing parts of the first leg part for fixing the circuit board to each other in the depth direction in the spring member paired in the width direction as claimed in claim 5. It is good to set it as the structure by which the fixing | fixed part of the part was made into the same position in the depth direction.

これによれば、深さ方向（回路基板の挿抜方向）において、固定部同士の位置が異なる構成に比べて、回路基板の変形（付勢力によって回路基板に生じる応力）を抑制することができる。   According to this, in the depth direction (circuit board insertion / extraction direction), deformation of the circuit board (stress generated in the circuit board due to the biasing force) can be suppressed as compared with the configuration in which the positions of the fixing portions are different.

さらに請求項６に記載のように、配列方向において、第１脚部の固定部が互いに異なる位置とされ、第２脚部の固定部が互いに異なる位置とされた構成とすると、幅方向で対をなすばね部材を、互いに干渉せずに動作させることができる。   Furthermore, as described in claim 6, in the arrangement direction, when the fixing portions of the first leg portions are different from each other and the fixing portions of the second leg portions are different from each other, the pair of the fixing portions of the second leg portions is different in the width direction. Can be operated without interfering with each other.

請求項７に記載のように、配列方向において、一方のばね部材は（ｎ＋１）個［ｎは正の整数］の固定部を有し、他方のばね部材はｎ個の固定部を有し、一方のばね部材の固定部間の領域１つにつき、他方のばね部材の固定部が１つ対向配置された構成とすると良い。   As described in claim 7, in the arrangement direction, one spring member has (n + 1) [n is a positive integer] fixing parts, and the other spring member has n fixing parts, It is preferable that one fixing portion of the other spring member is arranged opposite to each other between one fixing portion of one spring member.

これによれば、配列方向において、第１脚部の固定部同士、第２脚部の固定部同士が異なる位置でありながら、回路基板の変形を抑制することができる。   According to this, the deformation of the circuit board can be suppressed while the fixing portions of the first leg portions and the fixing portions of the second leg portions are different from each other in the arrangement direction.

また、請求項８に記載のように、一方のばね部材における第１脚部の固定部と第２脚部の固定部とを結んでなる第１仮想直線と、他方のばね部材における第１脚部の固定部と第２脚部の固定部とを結んでなる第２仮想直線とが、幅方向に垂直な平面において交差する構成としても良い。   In addition, as described in claim 8, the first imaginary straight line connecting the fixing portion of the first leg portion and the fixing portion of the second leg portion in one spring member, and the first leg in the other spring member. The second virtual straight line formed by connecting the fixed portion of the portion and the fixed portion of the second leg portion may intersect in a plane perpendicular to the width direction.

このような構成としても、配列方向において、第１脚部の固定部同士、第２脚部の固定部同士が異なる位置でありながら、回路基板の変形を抑制することができる。   Even with such a configuration, the deformation of the circuit board can be suppressed while the fixing portions of the first leg portions and the fixing portions of the second leg portions are in different positions in the arrangement direction.

請求項９に記載のように、軸部は、深さ方向において、複数の端子の接触部の少なくとも一部と重なるように設けられると良い。これによれば、深さ方向において、第１脚部の固定部と第２脚部の固定部との間に複数の端子の接触部の少なくとも一部が位置することとなるので、端子と電極との接触圧の変動をより確実に抑制することができる。   According to a ninth aspect of the present invention, the shaft portion may be provided so as to overlap at least part of the contact portions of the plurality of terminals in the depth direction. According to this, since at least a part of the contact portions of the plurality of terminals is located between the fixing portion of the first leg portion and the fixing portion of the second leg portion in the depth direction, the terminal and the electrode The fluctuation of the contact pressure with can be more reliably suppressed.

第１脚部５２及び第２脚部５３は、図３に示す初期状態での各固定部５２ｂ，５３ｂから軸部４０までの幅方向の距離が、固定状態での固定部５２ｂ，５３ｂから軸部４０までの距離よりも長くなっている。すなわち、第１脚部５２及び第２脚部５３が回路基板１１０の一面に接触した状態で、第１脚部５２及び第２脚部５３が弾性変形するようになっている。なお、図３では、固定状態における回路基板１１０の一面の位置を二点鎖線Ｌ１で示している。   The first leg portion 52 and the second leg portion 53 are configured such that the distance in the width direction from the fixed portions 52b and 53b to the shaft portion 40 in the initial state shown in FIG. 3 is the axis from the fixed portions 52b and 53b in the fixed state. It is longer than the distance to the portion 40. That is, the first leg portion 52 and the second leg portion 53 are elastically deformed in a state where the first leg portion 52 and the second leg portion 53 are in contact with one surface of the circuit board 110. In FIG. 3, the position of one surface of the circuit board 110 in the fixed state is indicated by a two-dot chain line L1.

第１脚部５２のうち、回動部５１との連結端５２ａから固定部５２ｂまでの部分は、連結端５２ａに近いほど深さ方向において軸部４０に近い傾斜部５２ｃとなっている。また、固定部５２ｂから先端までの部分は、先端に近いほど幅方向おいて固定部５２ｂから離れる傾斜部５２ｄとなっている。より詳しくは、初期状態において、第１脚部５２全体が、深さ方向で軸部４０の中心４１よりも溝部２１の底に対して遠い位置にある。また、第１脚部５２の連結端５２ａは、幅方向で軸部４０の中心４１よりも溝部２１に近い位置にある。さらに、幅方向に沿う仮想線と傾斜部５２ｃとのなす傾斜角が、軸部４０の中心４１と連結端５２ａとを結んでなる法線と、上記幅方向に沿う仮想線とのなす角よりも小さい角度となっている。   Of the first leg portion 52, the portion from the connecting end 52a to the rotating portion 51 to the fixed portion 52b is an inclined portion 52c that is closer to the shaft portion 40 in the depth direction as it is closer to the connecting end 52a. Further, the portion from the fixed portion 52b to the tip is an inclined portion 52d that is separated from the fixed portion 52b in the width direction as it is closer to the tip. More specifically, in the initial state, the entire first leg portion 52 is located farther from the bottom of the groove portion 21 than the center 41 of the shaft portion 40 in the depth direction. Further, the connecting end 52 a of the first leg portion 52 is located closer to the groove portion 21 than the center 41 of the shaft portion 40 in the width direction. Furthermore, the inclination angle formed between the imaginary line along the width direction and the inclined portion 52c is based on the angle formed between the normal line connecting the center 41 of the shaft portion 40 and the connecting end 52a and the imaginary line along the width direction. Is also a small angle.

一方、第２脚部５３のうち、回動部５１との連結端５３ａから固定部５３ｂまでの部分は、連結端５３ａに近いほど深さ方向において軸部４０に近い傾斜部５３ｃとなっている。また、固定部５３ｂよりも先端側の部分は、固定部５３ｂを曲げ部位とした折返し部５３ｄとなっている。この折返し部５３ｄは、初期状態で、固定部５３ｂよりも軸部４０に近い側に折り返されている。より詳しくは、上記初期状態において、第２脚部５２全体が、深さ方向で軸部４０の中心４１よりも先端面２０ａ（溝部２１の開口部）に対して遠い位置にある。また、第２脚部５３の連結端５３ａは、幅方向で軸部４０の中心４１とほぼ同じ位置にある。そして、幅方向に沿う仮想線と傾斜部５３ｃとのなす傾斜角が、軸部４０の中心４１と連結端５３ａとを結んでなる法線と、上記幅方向に沿う仮想線とのなす角よりも小さい角度となっている。   On the other hand, in the second leg portion 53, the portion from the connecting end 53a to the fixed portion 53b with the rotating portion 51 is an inclined portion 53c closer to the shaft portion 40 in the depth direction as it is closer to the connecting end 53a. . Further, a portion on the tip side of the fixing portion 53b is a folded portion 53d having the fixing portion 53b as a bending portion. The folded portion 53d is folded back closer to the shaft portion 40 than the fixed portion 53b in the initial state. More specifically, in the initial state, the entire second leg portion 52 is located farther from the front end surface 20a (opening portion of the groove portion 21) than the center 41 of the shaft portion 40 in the depth direction. Further, the connecting end 53a of the second leg portion 53 is located at substantially the same position as the center 41 of the shaft portion 40 in the width direction. Then, the inclination angle formed by the imaginary line along the width direction and the inclined portion 53c is based on the angle formed between the normal line connecting the center 41 of the shaft portion 40 and the connecting end 53a and the imaginary line along the width direction. Is also a small angle.

また、本実施形態では、上記初期状態において、図２，図４，及び図６に示すように、対をなすばね部材５０ａ，５０ｂの第１脚部５２の固定部５２ｂ同士が深さ方向でほぼ同じ位置とされ、第２脚部５３の固定部５３ｂ同士が深さ方向でほぼ同じ位置となっている。なお、図６においては、ばね部材５０ａの固定部５２ｂ，５３ｂを実線で示し、ばね部材５０ｂの固定部５２ｂ，５３ｂを破線で示している。さらに、図１，図５，及び図６に示すように、対をなすばね部材５０ａ，５０ｂにおいて、第１脚部５２の固定部５２ｂが配列方向で互いに異なる位置とされ、第２脚部５３の固定部５３ｂが配列方向で互いに異なる位置となっている。そして、図６に示すように、深さ方向において、第１脚部５２の固定部５２ｂと第２脚部５３の固定部５３ｂとの間に、複数の端子３０の接触部３１と回路基板１１０の電極との接続部が位置している。なお、図６では、接触部３１と回路基板１１０の電極との接続部を、該接続部の配置領域１１１（換言すれば電極の形成領域）として二点鎖線で示している。また、本実施形態では、図２及び図４に示すように、初期状態及び固定状態のいずれにおいても、第１脚部５２の固定部５２ｂが、軸部４０の中心４１とハウジング２０の先端面２０ａ（溝部２１の開口部）との間に位置し、第２脚部５３の固定部５３ｂが、軸部４０の中心４１と溝部２１の底との間に位置する。   In the present embodiment, in the initial state, as shown in FIGS. 2, 4, and 6, the fixing portions 52b of the first leg portions 52 of the paired spring members 50a and 50b are in the depth direction. The fixing portions 53b of the second leg portion 53 are substantially the same position in the depth direction. In FIG. 6, the fixing parts 52b and 53b of the spring member 50a are indicated by solid lines, and the fixing parts 52b and 53b of the spring member 50b are indicated by broken lines. Further, as shown in FIGS. 1, 5, and 6, in the spring members 50 a and 50 b that make a pair, the fixing portions 52 b of the first leg portions 52 are located at different positions in the arrangement direction, and the second leg portions 53. The fixing portions 53b are different from each other in the arrangement direction. As shown in FIG. 6, the contact portions 31 of the plurality of terminals 30 and the circuit board 110 are arranged between the fixing portion 52 b of the first leg portion 52 and the fixing portion 53 b of the second leg portion 53 in the depth direction. The connection part with the other electrode is located. In FIG. 6, the connection portion between the contact portion 31 and the electrode of the circuit board 110 is indicated by a two-dot chain line as the arrangement region 111 of the connection portion (in other words, the electrode formation region). In this embodiment, as shown in FIGS. 2 and 4, the fixed portion 52 b of the first leg portion 52 is connected to the center 41 of the shaft portion 40 and the distal end surface of the housing 20 in both the initial state and the fixed state. 20a (the opening portion of the groove portion 21), and the fixing portion 53b of the second leg portion 53 is located between the center 41 of the shaft portion 40 and the bottom of the groove portion 21.

各軸部４０におけるばね部材５０よりも突起先端部分には、配列方向においてばね部材５０の抜けを防止するための抜け防止部材６０が、回動部５１の回動を妨げないように設けられている。この抜け防止部材６０としては例えばゴムリングを採用することができる。本実施形態では、配列方向から見た平面図（例えば図２）において、便宜上、抜け防止部材６０の図示を省略している。   In each shaft portion 40, a protrusion preventing portion 60 for preventing the spring member 50 from coming off in the arrangement direction is provided at the tip end portion of the protrusion rather than the spring member 50 so as not to prevent the turning portion 51 from turning. Yes. For example, a rubber ring can be adopted as the removal preventing member 60. In this embodiment, in the plan view (for example, FIG. 2) viewed from the arrangement direction, the illustration of the removal preventing member 60 is omitted for convenience.

このように構成されたカードエッジコネクタ１０は、回路基板１１０及びケース１２０とともに電子装置１００を構成する。本実施形態では、回路基板１１０の両面に電極が形成されており、これにより、カードエッジコネクタ１０による電気的な接続経路を効率的に増やすことができる。また、ケース１２０は袋状をなし、その空間１２１に、回路基板１１０とともにハウジング２０を深さ方向において溝部２１の底よりも深い位置まで収容する。このケース１２０は、１つの部材のみからなっても良いし、複数の部材を組み合わせて構成することもできる。   The card edge connector 10 thus configured constitutes the electronic device 100 together with the circuit board 110 and the case 120. In the present embodiment, electrodes are formed on both surfaces of the circuit board 110, whereby the electrical connection paths by the card edge connector 10 can be efficiently increased. The case 120 has a bag shape, and the housing 20 together with the circuit board 110 is accommodated in the space 121 to a position deeper than the bottom of the groove portion 21 in the depth direction. The case 120 may be composed of only one member, or may be configured by combining a plurality of members.

次に、カードエッジコネクタ１０の溝部２１に回路基板１１０を挿入配置する際の、ばね部材５０の動作を、図７〜図１１を用いて説明する。   Next, the operation of the spring member 50 when the circuit board 110 is inserted and disposed in the groove 21 of the card edge connector 10 will be described with reference to FIGS.

本実施形態では、図７に示すように、ハウジング２０の溝部２１に回路基板１１０を挿入する際、対をなすばね部材５０ａ，５０ｂにおいて、第１脚部５２の傾斜部５２ｄに回路基板１１０の挿入先端が接するように、初期状態で、上記した構成のばね部材５０ａ，５０ｂが対をなす軸部４０ａ，４０ｂにそれぞれ取り付けられる。   In the present embodiment, as shown in FIG. 7, when the circuit board 110 is inserted into the groove portion 21 of the housing 20, the spring members 50 a and 50 b that make a pair are connected to the inclined portion 52 d of the first leg portion 52. In the initial state, the spring members 50a and 50b having the above-described configuration are attached to the pair of shaft portions 40a and 40b so that the insertion tip comes into contact with each other.

回路基板１１０の先端が傾斜部５２ｄに接した状態から、回路基板１１０を溝部２１の奥側（底側）へさらに挿入すると、第１脚部５２は回路基板１１０から挿入方向の力を受ける。このとき、第２脚部５３は変位可能な自由端状態にある。また、第１脚部５２の傾斜部５２ｃを介して回動部５１に上記力が伝達される。したがって、回動部５１は、図８に示すように一方向に回転する。このように、第１脚部５２の傾斜部５２ｃにて、回路基板１１０の挿入方向の力を、回動部５１を一方向に回転させる力に変換することができる。そして、回動部５１の回転により、第１脚部５２の固定部５２ｂが深さ方向において回路基板１１０の一面上に位置するように変位する。ばね部材５０ａにおいては、固定部５２ｂが回路基板１１０における軸部４０ａ側の一面１１０ａ上に位置するように変位し、ばね部材５０ｂにおいては、固定部５２ｂが回路基板１１０における軸部４０ｂ側の一面１１０ｂ上に位置するように変位する。したがって、回路基板１１０は、傾斜部５２ｄとの接触位置を固定部５２ｂに近づけながら溝部２１の底方向へ移動することとなる。また、回路基板１１０は、対をなすばね部材５０ａ，５０ｂの傾斜部５２ｄに接することで、深さ方向において位置が矯正される。   When the circuit board 110 is further inserted into the back side (bottom side) of the groove portion 21 from the state where the tip of the circuit board 110 is in contact with the inclined portion 52d, the first leg portion 52 receives a force in the insertion direction from the circuit board 110. At this time, the second leg 53 is in a displaceable free end state. Further, the force is transmitted to the rotating portion 51 through the inclined portion 52 c of the first leg portion 52. Therefore, the rotation part 51 rotates in one direction as shown in FIG. As described above, the force in the insertion direction of the circuit board 110 can be converted into the force for rotating the rotating portion 51 in one direction by the inclined portion 52 c of the first leg portion 52. Then, due to the rotation of the rotating part 51, the fixing part 52b of the first leg part 52 is displaced so as to be positioned on one surface of the circuit board 110 in the depth direction. In the spring member 50a, the fixed portion 52b is displaced so as to be positioned on the one surface 110a on the shaft portion 40a side of the circuit board 110, and in the spring member 50b, the fixed portion 52b is one surface on the shaft portion 40b side in the circuit board 110. It displaces so that it may be located on 110b. Therefore, the circuit board 110 moves toward the bottom of the groove portion 21 while bringing the contact position with the inclined portion 52d closer to the fixed portion 52b. Further, the position of the circuit board 110 is corrected in the depth direction by contacting the inclined portions 52d of the paired spring members 50a and 50b.

そして、図９に示すように、回路基板１１０の一面に第１脚部５２の固定部５２ｂが乗りあがり、固定部５２ｂが回路基板１１０の一面上に位置するまで、回路基板１１０の挿入にともない回動部５１が一方向に回転する。このように、第１脚部５２に回路基板１１０が接触しても、第１脚部５２により付勢力を付与せずに回路基板１１０を奥側へスムースに挿入することができる。なお、図９では、回路基板１１０の一面１１０ａにばね部材５０ａにおける第１脚部５２の固定部５２ｂが乗り上げた状態で、該固定部５２ｂが回路基板１１０の一面１１０ａと離れた状態を例示している。また、回路基板１１０の一面１１０ｂにばね部材５０ｂにおける第１脚部５２の固定部５２ｂが乗り上げた状態で、該固定部５２ｂが回路基板１１０の一面１１０ｂと離れた状態を例示している。   Then, as shown in FIG. 9, as the circuit board 110 is inserted until the fixing portion 52 b of the first leg portion 52 rides on one surface of the circuit board 110 and the fixing portion 52 b is positioned on one surface of the circuit board 110. The rotating part 51 rotates in one direction. Thus, even if the circuit board 110 contacts the first leg portion 52, the circuit board 110 can be smoothly inserted to the back without applying an urging force by the first leg portion 52. 9 illustrates a state in which the fixing portion 52b of the first leg portion 52 of the spring member 50a is mounted on the one surface 110a of the circuit board 110, and the fixing portion 52b is separated from the one surface 110a of the circuit board 110. ing. Further, the state in which the fixing portion 52b of the first leg portion 52 of the spring member 50b rides on the one surface 110b of the circuit board 110 and the fixing portion 52b is separated from the one surface 110b of the circuit board 110 is illustrated.

図９に示す状態から、回路基板１１０を溝部２１の奥側へさらに挿入すると、回路基板１１０の先端は第２脚部５３の傾斜部５３ｃに接触する。この接触状態から、回路基板１１０を溝部２１の奥側へさらに挿入すると、第２脚部５３は回路基板１１０から挿入方向の力を受ける。このとき、第２脚部５３の傾斜部５３ｃを介して回動部５１に上記力が伝達されるため、回動部５１は、図１０に示すように反対方向に回転する。このように、第２脚部５３の傾斜部５３ｃにて、回路基板１１０の挿入方向の力を、回動部５１を反対方向に回転させる力に変換することができる。   When the circuit board 110 is further inserted into the back side of the groove portion 21 from the state shown in FIG. 9, the tip of the circuit board 110 comes into contact with the inclined portion 53 c of the second leg portion 53. When the circuit board 110 is further inserted into the back side of the groove portion 21 from this contact state, the second leg portion 53 receives a force in the insertion direction from the circuit board 110. At this time, since the force is transmitted to the rotating portion 51 via the inclined portion 53c of the second leg portion 53, the rotating portion 51 rotates in the opposite direction as shown in FIG. As described above, the force in the insertion direction of the circuit board 110 can be converted into the force for rotating the rotating portion 51 in the opposite direction at the inclined portion 53 c of the second leg portion 53.

そして、図１１に示すように、回路基板１１０の一面に第２脚部５３の固定部５３ｂが乗りあがり、固定部５３ｂが回路基板１１０の一面上に位置するまで、回路基板１１０の挿入にともない回動部５１が反対方向に回転する。このとき、上記したように、幅方向における固定部５２ｂ，５３ｂから軸部４０までの距離が、固定状態よりも初期状態で長いため、第１脚部５２及び第２脚部５３が弾性変形状態となる。したがって、第１脚部５２の固定部５２ｂ及び第２脚部５３の固定部５３ｂの両方が回路基板１１０の一面に接触すると、図１１に示すように、回路基板１１０に付勢力が与えられ、回路基板１１０が固定される。本実施形態では、図１１に示すように、ばね部材５０ａから紙面下向きの付勢力が回路基板１１０に作用し、ばね部材５０ｂから紙面上向きの付勢力が作用することで、回路基板１１０が固定（保持）される。   Then, as shown in FIG. 11, as the circuit board 110 is inserted until the fixing portion 53 b of the second leg portion 53 rides on one surface of the circuit board 110 and the fixing portion 53 b is positioned on one surface of the circuit board 110. The rotating part 51 rotates in the opposite direction. At this time, as described above, since the distance from the fixed portions 52b and 53b to the shaft portion 40 in the width direction is longer in the initial state than in the fixed state, the first leg portion 52 and the second leg portion 53 are in an elastically deformed state. It becomes. Therefore, when both the fixing portion 52b of the first leg portion 52 and the fixing portion 53b of the second leg portion 53 come into contact with one surface of the circuit board 110, an urging force is applied to the circuit board 110 as shown in FIG. The circuit board 110 is fixed. In the present embodiment, as shown in FIG. 11, the downward biasing force from the spring member 50a acts on the circuit board 110, and the upward biasing force from the spring member 50b acts on the circuit board 110, thereby fixing the circuit board 110 ( Retained).

なお、カードエッジコネクタ１０から回路基板１１０を引き抜く際には、第１脚部５２及び第２脚部５３のいずれも折返し構造となっているので、物理的な接触による抵抗を低減することができる。また、第２脚部５３が回路基板１１０から外れて自由端となるとともに、第１脚部５２の弾性変形エネルギーを開放するように回動部５１が一方向に回動する。これにより回路基板１１０に作用している付勢力がなくなり、回路基板１１０を容易に引き抜くことができる。   When the circuit board 110 is pulled out from the card edge connector 10, since both the first leg portion 52 and the second leg portion 53 have a folded structure, resistance due to physical contact can be reduced. . Further, the second leg portion 53 is detached from the circuit board 110 to become a free end, and the rotating portion 51 is rotated in one direction so as to release the elastic deformation energy of the first leg portion 52. As a result, the urging force acting on the circuit board 110 is eliminated, and the circuit board 110 can be easily pulled out.

次に、本実施形態に示したカードエッジコネクタ１０の特徴部分の効果について説明する。   Next, the effect of the characteristic part of the card edge connector 10 shown in this embodiment will be described.

本実施形態では、回路基板１１０の挿入時にばね部材５０の第１脚部５２に接触しても、第１脚部５２は、回路基板１１０から受ける挿入方向の力を、固定部５２ｂを含む第１脚部５２全体が回路基板１１０の一面上に位置するように回動部５１を一方向に回転させる力に変換することができる。したがって、回路基板１１０が第１脚部５２に接触しても、ばね部材５０は回路基板１１０に付勢力を付与しない。このため、回路基板１１０を溝部２１の奥側へスムースに挿入することができる。   In the present embodiment, even if the first leg portion 52 of the spring member 50 contacts the first leg portion 52 when the circuit board 110 is inserted, the first leg portion 52 includes the fixing portion 52b. This can be converted into a force that rotates the rotating portion 51 in one direction so that the entire leg portion 52 is positioned on one surface of the circuit board 110. Therefore, even if the circuit board 110 contacts the first leg portion 52, the spring member 50 does not apply a biasing force to the circuit board 110. For this reason, the circuit board 110 can be smoothly inserted into the back side of the groove 21.

また、第２脚部５３は、第２脚部５３が回路基板１１０から受ける挿入方向の力を、固定部５３ｂを含む第２脚部５３全体が回路基板１１０の一面上に位置するように、回動部５１を反対方向に回転させる力に変換することができる。そして、この回転により、第１脚部５２及び第２脚部５３は、ともに弾性変形状態で回路基板１１０の一面に接触する。したがって、第１脚部５２及び第２脚部５３が回路基板１１０に接触した状態で回路基板１１０に付勢力を与え、回路基板１１０を固定することができる。ばね部材５０は、複数の端子３０の接触部３１の両端側にそれぞれ設けられているため、配列方向において回路基板１１０を安定的に固定することができる。また、各固定部５２ｂ，５３ｂは、深さ方向において異なる位置で回路基板１１０に接触するので、深さ方向においても回路基板１１０を安定的に固定することができる。したがって、端子３０と電極との接触圧の変動を抑制することができる。   Further, the second leg portion 53 is configured so that the second leg portion 53 receives the force in the insertion direction that the second leg portion 53 receives from the circuit board 110 so that the entire second leg portion 53 including the fixing portion 53b is positioned on one surface of the circuit board 110. It can convert into the force which rotates the rotation part 51 in the opposite direction. By this rotation, both the first leg portion 52 and the second leg portion 53 come into contact with one surface of the circuit board 110 in an elastically deformed state. Therefore, the circuit board 110 can be fixed by applying a biasing force to the circuit board 110 in a state where the first leg 52 and the second leg 53 are in contact with the circuit board 110. Since the spring members 50 are respectively provided on both end sides of the contact portions 31 of the plurality of terminals 30, the circuit board 110 can be stably fixed in the arrangement direction. Moreover, since each fixing | fixed part 52b and 53b contacts the circuit board 110 in a different position in the depth direction, the circuit board 110 can be stably fixed also in the depth direction. Therefore, fluctuations in contact pressure between the terminal 30 and the electrode can be suppressed.

また、ばね部材５０によって端子３０と電極との接触圧の変動を抑制することができるため、回路基板１１０に対する端子３０のばね力を従来よりも小さくすることができる。そして、これにより、回路基板１１０の挿抜にともなうメッキ層の剥がれなど端子３０や電極の損傷・変形を抑制することができる。すなわち、端子３０と電極との接触圧の変動を抑制でき、且つ、回路基板１１０との電気的な接続信頼性を確保することができる。   In addition, since the fluctuation of the contact pressure between the terminal 30 and the electrode can be suppressed by the spring member 50, the spring force of the terminal 30 with respect to the circuit board 110 can be made smaller than before. Thereby, damage / deformation of the terminal 30 and the electrode such as peeling of the plating layer accompanying the insertion / extraction of the circuit board 110 can be suppressed. That is, fluctuations in contact pressure between the terminal 30 and the electrode can be suppressed, and electrical connection reliability with the circuit board 110 can be ensured.

特に本実施形態では、ハウジング２０に軸部４０を設け、該軸部４０にばね部材５０を取り付けた簡素な構成で、上記効果を奏することができる。また、固定状態で、同じ回動部５１に連結された第１脚部５２及び第２脚部５３の固定部５２ｂ，５３ｂ間に、端子３０の接触部３１と回路基板１１０の電極との接続部、換言すれば、複数の端子３０の接触部３１、が位置する。したがって、配列方向両端に位置するばね部材５０の４つの脚部５２，５３により、端子３０の接触部３１と回路基板１１０の電極との接続部を取り囲み、リジッドに拘束することができる。このため、端子と電極との接触圧の変動をより効果的に抑制することができる。   In particular, in the present embodiment, the above effect can be achieved with a simple configuration in which the shaft portion 40 is provided in the housing 20 and the spring member 50 is attached to the shaft portion 40. Further, in the fixed state, the contact portion 31 of the terminal 30 and the electrode of the circuit board 110 are connected between the fixed portions 52 b and 53 b of the first leg portion 52 and the second leg portion 53 connected to the same rotating portion 51. Part, in other words, the contact parts 31 of the plurality of terminals 30 are located. Accordingly, the four leg portions 52 and 53 of the spring member 50 located at both ends in the arrangement direction can surround the connection portion between the contact portion 31 of the terminal 30 and the electrode of the circuit board 110 and can be restrained rigidly. For this reason, the fluctuation | variation of the contact pressure of a terminal and an electrode can be suppressed more effectively.

また、回路基板１１０が溝部２１入口側の第１脚部５２に接触しても付勢力を生じず、奥側の第２脚部５３に接触して付勢力を生じるようになっている。したがって、深さ方向において複数個所で回路基板１１０を固定する構成でありながら、回路基板１１０をハウジング２０の溝部２１奥側まで容易に挿入することができる。   Further, no urging force is generated even when the circuit board 110 contacts the first leg portion 52 on the inlet side of the groove portion 21, and an urging force is generated by contacting the second leg portion 53 on the back side. Therefore, the circuit board 110 can be easily inserted to the back side of the groove portion 21 of the housing 20 while the circuit board 110 is fixed at a plurality of positions in the depth direction.

また、本実施形態では、ばね部材５０の第２脚部５３において、回動部５１との連結端５３ａから固定部５３ｂまでの部分が、連結端５３ａに近いほど深さ方向において軸部４０に近い傾斜部５３ｃとなっている。また、固定部５３ｂを曲げ部位として固定部５３ｂよりも先端側の部分が折返し部５３ｄとなっている。したがって、回路基板１１０の挿抜時における回路基板１１０と第２脚部５３との物理的な接触による抵抗を小さくすることができる。   Moreover, in this embodiment, in the 2nd leg part 53 of the spring member 50, the part from the connection end 53a with the rotation part 51 to the fixing | fixed part 53b becomes the axial part 40 in the depth direction, so that it is near the connection end 53a. It is a close inclined portion 53c. Further, with the fixed portion 53b as a bending portion, a portion closer to the tip than the fixed portion 53b is a folded portion 53d. Therefore, the resistance due to physical contact between the circuit board 110 and the second leg portion 53 when the circuit board 110 is inserted and removed can be reduced.

また、本実施形態では、対をなすばね部材５０ａ，５０ｂにより、回路基板１１０の両面１１０ａ，１１０ｂ側から付勢力を与えて回路基板１１０を固定する。したがって、回路基板１１０の一面側にばね部材５０が位置し、回路基板１１０の他方の面側に付勢力を付与しない支持部が位置し、ばね部材５０ａと支持部（後述する図２６及び図２７参照）とにより回路基板１１０を固定する構成に比べて、幅方向における回路基板１１０の位置調整代を大きくすることができる。例えば、反りの大きい回路基板１１０にも対応することができる。また、本実施形態では、対をなすばね部材５０ａ，５０ｂの付勢力のバランスのとれた位置に回路基板１１０が保持されるので、反りなどにより回路基板１１０に過大な付勢力が付与されるのを抑制することもできる。   In the present embodiment, the circuit board 110 is fixed by applying a biasing force from the both sides 110a and 110b of the circuit board 110 by the paired spring members 50a and 50b. Therefore, the spring member 50 is located on one surface side of the circuit board 110, and a support portion that does not apply a biasing force is located on the other surface side of the circuit board 110, and the spring member 50a and the support portion (FIGS. 26 and 27 described later). Therefore, the position adjustment allowance of the circuit board 110 in the width direction can be increased compared to the configuration in which the circuit board 110 is fixed. For example, it is possible to deal with a circuit board 110 having a large warp. In the present embodiment, since the circuit board 110 is held at a position where the urging forces of the paired spring members 50a and 50b are balanced, an excessive urging force is applied to the circuit board 110 due to warpage or the like. Can also be suppressed.

また、本実施形態では、対をなすばね部材５０ａ，５０ｂにおいて、第１脚部５２の固定部５２ｂの深さ方向の位置が固定状態でほぼ同じであり、第２脚部５３の固定部５３ｂの深さ方向の位置が固定状態でほぼ同じである。したがって、深さ方向において、固定部５２ｂ同士、固定部５３ｂ同士の位置が異なる構成に比べて、回路基板１１０の変形を抑制することができる。一方、配列方向において、第１脚部５２の固定部５２ｂが互いに異なる位置とされ、第２脚部５３の固定部５３ｂが互いに異なる位置とされているため、対をなすばね部材５０ａ，５０ｂを、互いに干渉せずに動作させることができる。   In the present embodiment, in the spring members 50a and 50b that make a pair, the position in the depth direction of the fixing portion 52b of the first leg portion 52 is substantially the same in the fixed state, and the fixing portion 53b of the second leg portion 53 is the same. The position in the depth direction is substantially the same in the fixed state. Therefore, the deformation of the circuit board 110 can be suppressed as compared with the configuration in which the positions of the fixing portions 52b and the fixing portions 53b are different in the depth direction. On the other hand, in the arrangement direction, the fixing portions 52b of the first leg portions 52 are at different positions, and the fixing portions 53b of the second leg portions 53 are at different positions. Can be operated without interfering with each other.

また、本実施形態では、軸部４０が、配列方向に沿って延び、外形輪郭が真円状の円柱形状をなしている。このような軸部４０を設けることで、ばね部材５０の回動部５１を回動しやすくすることができる。   Moreover, in this embodiment, the axial part 40 has extended along the arrangement | sequence direction, and has comprised the cylindrical shape whose outer shape outline is a perfect circle shape. By providing such a shaft portion 40, the rotation portion 51 of the spring member 50 can be easily rotated.

また、本実施形態では、ばね部材５０の回動部５１が、中心角１８０度より大きい範囲で軸部４０周りに延びている。したがって、別途抜け防止部を設けなくとも、軸部４０周りにおいて回動部５１を軸部４０に保持することができる。   In the present embodiment, the rotating portion 51 of the spring member 50 extends around the shaft portion 40 in a range larger than the central angle of 180 degrees. Therefore, the rotation part 51 can be held on the shaft part 40 around the shaft part 40 without providing a separate prevention part.

なお、本実施形態では、回路基板１１０の挿入時に、回路基板１１０が第１脚部５２の傾斜部５２ｄに接触する例を示した。しかしながら、図１２に示すように、回路基板１１０が第１脚部５２に接触しない場合でも、第２脚部５３に回路基板１１０が接触し、回動部５１が反対方向に回転することで、第１脚部５２及び第２脚部５３により回路基板１１０に付勢力を与えて回路基板１１０を固定することができる。   In the present embodiment, the example in which the circuit board 110 contacts the inclined portion 52d of the first leg 52 when the circuit board 110 is inserted is shown. However, as shown in FIG. 12, even when the circuit board 110 does not contact the first leg portion 52, the circuit board 110 contacts the second leg portion 53, and the rotating portion 51 rotates in the opposite direction. The circuit board 110 can be fixed by applying a biasing force to the circuit board 110 by the first leg 52 and the second leg 53.

（変形例）
本実施形態では、幅方向において、主として軸部４０の中心４１よりも溝部２１に近い側に第１脚部５２及び第２脚部５３が位置し、主として軸部４０の中心４１よりも溝部２１から遠い側に回動部５１が位置する例を示した。しかしながら、図１３に示すように、幅方向において、主として軸部４０の中心４１よりも溝部２１に近い側に、第１脚部５２及び第２脚部５３とともに回動部５１が位置するばね部材５０を採用することもできる。なお、図１３に示す回動部５１は、１８０度よりも大きい中心角θｃを有している。 (Modification)
In the present embodiment, in the width direction, the first leg portion 52 and the second leg portion 53 are mainly located closer to the groove portion 21 than the center 41 of the shaft portion 40, and mainly the groove portion 21 than the center 41 of the shaft portion 40. The example which the rotation part 51 is located in the side far from is shown. However, as shown in FIG. 13, in the width direction, the spring member in which the rotating part 51 is located together with the first leg part 52 and the second leg part 53 mainly on the side closer to the groove part 21 than the center 41 of the shaft part 40. 50 can also be adopted. 13 has a central angle θc larger than 180 degrees.

本実施形態では、回動部５１の一端に第１脚部５２が連結され、他端に第２脚部５３が連結される例を示した。しかしながら、例えば図１４（ａ），（ｂ）に示すように、回動部５１における端部とは異なる部位に第１脚部５２の連結端５２ａが連結された構成としても良い。同様に、回動部５１の端部とは異なる部位に第２脚部５３の連結端５３ａが連結された構成としても良い。これによれば、回動部５１の軸部４０に沿う長さを長くして軸部４０からの抜けを防止するとともに、連結端５２ａ，５３ａの位置を深さ方向において溝部２１からより離れた位置として、回路基板１１０から挿入方向の力を受けて回動部５１を回動しやすくすることができる。   In the present embodiment, an example is shown in which the first leg 52 is connected to one end of the rotating part 51 and the second leg 53 is connected to the other end. However, for example, as shown in FIGS. 14A and 14B, the connecting end 52 a of the first leg portion 52 may be connected to a portion different from the end portion of the rotating portion 51. Similarly, the connection end 53 a of the second leg portion 53 may be connected to a portion different from the end portion of the rotating portion 51. According to this, the length along the shaft part 40 of the rotating part 51 is lengthened to prevent the shaft part 40 from coming off, and the positions of the connecting ends 52a, 53a are further away from the groove part 21 in the depth direction. As a position, the rotation part 51 can be easily rotated by receiving a force in the insertion direction from the circuit board 110.

本実施形態では、第２脚部５３のうち、回動部５１との連結端５３ａから固定部５３ｂまでの部分が、初期状態で連結端５３ａに近いほど深さ方向において軸部４０に近い傾斜部５３ｃとされ、固定部５３ｂよりも先端側の部分が、幅方向において軸部４０に近い折返し部５３ｄとされる例を示した。しかしながら、例えば図１５に示すように、折返し部５３ｄのないばね部材５０を採用しても良い。ただし、折返し部５３ｄを有さないと、特にカードエッジコネクタ１０から回路基板１１０を抜く際の物理的な接触による抵抗が大きくなる。また、連結端５３ａから固定部５３ｂまでを繋ぐ部分についても、上記傾斜部５３ｃに限定されるものではない。第２脚部５３としては、回路基板１１０が接触して挿入方向の力を受けると、該力を回動部５１を反対方向に回転させる力に変換して、固定部５３ｂを含む第２脚部５３全体が回路基板１１０の一面上に位置できるように、連結端５３ａの位置、回動部５１から延びる方向、及び長さが設定されれば良い。また、第１脚部５２についても、回路基板１１０が接触して挿入方向の力を受けると、該力を回動部５１を一方向に回転させる力に変換して、固定部５２ｂを含む第１脚部５２全体が回路基板１１０の一面上に位置できるように、連結端５２ａの位置、回動部５１から延びる方向、及び長さが設定されれば良い。   In the present embodiment, in the second leg portion 53, the portion from the connecting end 53a to the fixed portion 53b with the rotating portion 51 is inclined closer to the shaft portion 40 in the depth direction as it is closer to the connecting end 53a in the initial state. An example is shown in which the portion 53c is a folded portion 53d that is closer to the shaft portion 40 in the width direction than the fixed portion 53b. However, for example, as shown in FIG. 15, a spring member 50 without the folded portion 53 d may be employed. However, if the folded portion 53d is not provided, resistance due to physical contact particularly when the circuit board 110 is pulled out from the card edge connector 10 increases. Further, the portion connecting the connecting end 53a to the fixed portion 53b is not limited to the inclined portion 53c. As the second leg portion 53, when the circuit board 110 contacts and receives a force in the insertion direction, the second leg portion 53 converts the force into a force for rotating the rotating portion 51 in the opposite direction, and includes the second leg including the fixing portion 53b. The position of the connecting end 53a, the direction extending from the rotating portion 51, and the length may be set so that the entire portion 53 can be positioned on one surface of the circuit board 110. In addition, when the circuit board 110 comes into contact with the first leg portion 52 and receives a force in the insertion direction, the first leg portion 52 converts the force into a force for rotating the rotating portion 51 in one direction, and includes the fixing portion 52b. The position of the connecting end 52a, the direction extending from the rotating portion 51, and the length may be set so that the entire leg portion 52 can be positioned on one surface of the circuit board 110.

本実施形態では、柱状の軸部４０として外形輪郭が真円の例を示した。しかしながら、軸部４０の外形輪郭は上記例に限定されるものではない。例えば図１６に示すように、外径輪郭が鼓状の軸部４０を採用することもできる。外周面として弧面の部分を有すると回動部５１が回動しやすい。さらには、配列方向に沿って延びる柱状に限定されるものでもない。回動部５１が回動できる形状であれば良い。   In the present embodiment, an example in which the outer contour is a perfect circle is shown as the columnar shaft portion 40. However, the outer contour of the shaft portion 40 is not limited to the above example. For example, as shown in FIG. 16, it is possible to employ a shaft portion 40 whose outer diameter contour is a drum shape. When the arc surface portion is provided as the outer peripheral surface, the rotating portion 51 is easy to rotate. Furthermore, it is not limited to a columnar shape extending along the arrangement direction. Any shape that allows the rotation part 51 to rotate can be used.

深さ方向における第１脚部５２の固定部５２ｂ及び第２脚部５３の固定部５３ｂの配置としては、固定状態で、固定部５２ｂと固定部５３ｂの間に少なくとも軸部４０の中心４１が位置すれば良い。これにより、深さ方向において回路基板１１０を安定的に固定することができる。好ましくは、深さ方向において、複数の端子３０の接触部３１の少なくとも一部と重なるように、軸部４０が設けられると良い。これによれば、深さ方向において、第１脚部５２の固定部５２ｂと第２脚部５３の固定部５３ｂとの間に、端子３０の接触部３１と回路基板１１０の電極との接続部の少なくとも一部が位置することとなり、端子と電極との接触圧の変動を効果的に抑制することができる。さらには、本実施形態に示したように、深さ方向において、第１脚部５２の固定部５２ｂと第２脚部５３の固定部５３ｂとの間に、複数の端子３０の接触部３１と回路基板１１０の電極との接続部が位置すると、端子と電極との接触圧の変動をより効果的に抑制することができる。   As the arrangement of the fixing portion 52b of the first leg portion 52 and the fixing portion 53b of the second leg portion 53 in the depth direction, at least the center 41 of the shaft portion 40 is between the fixing portion 52b and the fixing portion 53b in the fixed state. It only has to be located. Thereby, the circuit board 110 can be stably fixed in the depth direction. Preferably, the shaft portion 40 is provided so as to overlap at least a part of the contact portions 31 of the plurality of terminals 30 in the depth direction. According to this, in the depth direction, a connecting portion between the contact portion 31 of the terminal 30 and the electrode of the circuit board 110 between the fixing portion 52b of the first leg portion 52 and the fixing portion 53b of the second leg portion 53. Thus, at least a part of is located, and the fluctuation of the contact pressure between the terminal and the electrode can be effectively suppressed. Furthermore, as shown in the present embodiment, the contact portions 31 of the plurality of terminals 30 are arranged between the fixing portion 52b of the first leg portion 52 and the fixing portion 53b of the second leg portion 53 in the depth direction. If the connection part with the electrode of the circuit board 110 is located, the fluctuation | variation of the contact pressure of a terminal and an electrode can be suppressed more effectively.

また、本実施形態では、図６に示すように、同じ回動部５１に連結された２つの脚部５２,５３の固定部５２ｂ，５３ｂが、配列方向においてほぼ同じ位置とされ、対をなすばね部材５０ａ，５０ｂにおいて、一方のばね部材５０ａの固定部５２ｂ，５３ｂと他方のばね部材５０ｂの固定部５２ｂ，５３ｂとが配列方向においてずれて設けられる。そして、配列方向における両端部において、一方の端部ではばね部材５０ａが外側、他方の端部ではばね部材５０ｂが外側に位置する例を示した。しかしながら、配列方向における両端部において、両端部でばね部材５０ａ（又は両端部でばね部材５０ｂ）が外側に位置するようにしても良い。   Further, in the present embodiment, as shown in FIG. 6, the fixed portions 52b and 53b of the two leg portions 52 and 53 connected to the same rotating portion 51 are set at substantially the same position in the arrangement direction to form a pair. In the spring members 50a and 50b, the fixing portions 52b and 53b of one spring member 50a and the fixing portions 52b and 53b of the other spring member 50b are provided so as to be shifted in the arrangement direction. In the both end portions in the arrangement direction, the example is shown in which the spring member 50a is located outside at one end and the spring member 50b is located outside at the other end. However, at both ends in the arrangement direction, the spring members 50a (or the spring members 50b at both ends) may be located outside at both ends.

（第２実施形態）
本実施形態に係るカードエッジコネクタ１０は、ばね部材５０における回動部５１の回動範囲を規制するストッパをハウジング２０が有する点を特徴とする。 (Second Embodiment)
The card edge connector 10 according to the present embodiment is characterized in that the housing 20 has a stopper that regulates the rotation range of the rotation portion 51 of the spring member 50.

図１７に示すストッパ７０は、主として反対方向に回転する回動部５１の回動範囲を規制するものである。図１７では、ストッパ７０が、第１脚部５２の傾斜部５２ｃに対し、反対方向側に設けられている。このため、回動部５１が反対方向に回転し、第１脚部５２の傾斜部５２ｃがストッパ７０に接触すると、回動部５１がそれ以上回転できなくなる。したがって、回路基板１１０を挿入する前や回路基板１１０を抜いた後の初期状態での、ばね部材５０の過大な位置ズレを抑制し、回路基板１１０挿入時にばね部材５０により回路基板１１０を確実に固定することができる。例えば回路基板１１０を溝部２１に挿入する際に、回路基板１１０の先端を第１脚部５２の傾斜部５２ｄに接触させることができる。   The stopper 70 shown in FIG. 17 regulates the rotation range of the rotation unit 51 that rotates mainly in the opposite direction. In FIG. 17, the stopper 70 is provided on the opposite direction side with respect to the inclined portion 52 c of the first leg portion 52. For this reason, if the rotation part 51 rotates in the opposite direction and the inclined part 52c of the 1st leg part 52 contacts the stopper 70, the rotation part 51 cannot rotate any more. Therefore, excessive displacement of the spring member 50 in an initial state before the circuit board 110 is inserted or after the circuit board 110 is pulled out is suppressed, and the circuit board 110 is reliably secured by the spring member 50 when the circuit board 110 is inserted. Can be fixed. For example, when the circuit board 110 is inserted into the groove part 21, the tip of the circuit board 110 can be brought into contact with the inclined part 52 d of the first leg part 52.

このようなストッパ７０は、軸部４０と同様に構成することができる。本実施形態では、軸部４０同様、ハウジング２０の一部として側面２０ｂから突起してストッパ７０が形成されている。なお、図１７では、第１脚部５２に接触して回動部５１の反対方向の回転を規制するようにストッパ７０が設けられる例を示した。しかしながら、第２脚部５３の傾斜部５３ｃに対し、反対方向側にストッパ７０を設けることで、ストッパ７０に第２脚部５３が接触し、回動部５１の反対方向の回転が規制されるようにしても良い。   Such a stopper 70 can be configured similarly to the shaft portion 40. In the present embodiment, like the shaft portion 40, a stopper 70 is formed as a part of the housing 20 so as to protrude from the side surface 20b. FIG. 17 shows an example in which the stopper 70 is provided so as to contact the first leg portion 52 and restrict the rotation of the rotating portion 51 in the opposite direction. However, by providing the stopper 70 on the opposite direction side with respect to the inclined portion 53c of the second leg portion 53, the second leg portion 53 comes into contact with the stopper 70, and the rotation of the rotating portion 51 in the opposite direction is restricted. You may do it.

図１８に示すストッパ７１は、主として一方向に回転する回動部５１の回動範囲を規制するものである。図１８では、ストッパ７１が、第２脚部５３の傾斜部５３ｃに対し、一方向側に設けられている。このため、回動部５１が一方向に回転し、第２脚部５３の傾斜部５３ｃがストッパ７１に接触すると、回動部５１がそれ以上回転できなくなる。したがって、初期状態でのばね部材５０の過大な位置ズレを抑制し、回路基板１１０挿入時にばね部材５０により回路基板１１０を確実に固定することができる。例えば回路基板１１０を溝部２１に挿入する際に、回路基板１１０の先端を第２脚部５３の傾斜部５３ｃに接触させることができる。   The stopper 71 shown in FIG. 18 regulates the rotation range of the rotation unit 51 that rotates mainly in one direction. In FIG. 18, the stopper 71 is provided on one side with respect to the inclined portion 53 c of the second leg portion 53. For this reason, when the rotation part 51 rotates in one direction and the inclined part 53c of the 2nd leg part 53 contacts the stopper 71, the rotation part 51 cannot rotate any more. Therefore, an excessive positional shift of the spring member 50 in the initial state can be suppressed, and the circuit board 110 can be reliably fixed by the spring member 50 when the circuit board 110 is inserted. For example, when the circuit board 110 is inserted into the groove portion 21, the tip of the circuit board 110 can be brought into contact with the inclined portion 53 c of the second leg portion 53.

なお、図１８では、第２脚部５３に接触して回動部５１の一方向の回転を規制するようにストッパ７１が設けられる例を示した。しかしながら、第１脚部５２の傾斜部５２ｃに対し、一方向側にストッパ７１を設けることで、ストッパ７１に第１脚部５２が接触し、回動部５１の反対方向の回転が規制されるようにしても良い。また、このストッパ７１についても、ストッパ７０同様設けることができる。   FIG. 18 shows an example in which the stopper 71 is provided so as to contact the second leg portion 53 and restrict the rotation of the rotating portion 51 in one direction. However, by providing the stopper 71 on one direction side with respect to the inclined portion 52c of the first leg portion 52, the first leg portion 52 comes into contact with the stopper 71, and the rotation of the rotating portion 51 in the opposite direction is restricted. You may do it. Further, the stopper 71 can be provided similarly to the stopper 70.

図１９（ａ）に示す例では、上記した２つのストッパ７０，７１を有している。このように２つのストッパ７０，７１を有すると、一方向及び反対方向の両方向の回転について、回動部５１の回転範囲を規制することができる。すなわち、回動部５１の回動可能範囲をより狭い範囲に規制することができる。したがって、例えば図１９（ａ）に示すように、中心角が１８０度以下の回動部５１を有するばね部材５０を採用しても、軸部４０周りにおいて軸部４０からばね部材５０が抜け落ちるのを防ぐことができる。   The example shown in FIG. 19A has the two stoppers 70 and 71 described above. When the two stoppers 70 and 71 are provided in this way, the rotation range of the rotating portion 51 can be restricted with respect to the rotation in both the one direction and the opposite direction. That is, the pivotable range of the pivoting part 51 can be restricted to a narrower range. Therefore, for example, as shown in FIG. 19A, even if a spring member 50 having a rotating portion 51 having a central angle of 180 degrees or less is employed, the spring member 50 falls off from the shaft portion 40 around the shaft portion 40. Can be prevented.

また、図１９（ｂ）に示すように、ストッパ７０，７１両方の機能を有する兼用のストッパ７２を採用することができる。このストッパ７２は、軸部４０の外周面と略平行に、所定範囲にわたって軸部４０周りに設けられている。すなわち、軸部４０とストッパ７２の間に回動部５１が配置されている。このストッパ７２によっても、中心角が１８０度以下の回動部５１を有するばね部材５０が軸部４０から抜け落ちるのを防ぐことができる。なお、図１９（ａ）に示すストッパ７０，７１と、図１９（ｂ）に示すストッパ７２をいずれも有する構成を採用することもできる。   Further, as shown in FIG. 19B, a combined stopper 72 having both functions of the stoppers 70 and 71 can be employed. The stopper 72 is provided around the shaft portion 40 over a predetermined range substantially parallel to the outer peripheral surface of the shaft portion 40. That is, the rotating part 51 is arranged between the shaft part 40 and the stopper 72. This stopper 72 can also prevent the spring member 50 having the rotating portion 51 having a central angle of 180 degrees or less from falling off the shaft portion 40. It is also possible to employ a configuration having both the stoppers 70 and 71 shown in FIG. 19A and the stopper 72 shown in FIG.

図２０に示す例では、第１実施形態の図１３に示したばね部材５０に、図１９（ｂ）に示すストッパ７２を組み合わせている。これによれば、ストッパ７２により回動部５１の回動範囲を規制することができる。また、中心角が１８０度以下の回動部５１を有するばね部材５０を採用し、且つ、軸部４０に対して回動部５１が鉛直下方に位置しても、ばね部材５０が軸部４０から抜け落ちるのを防ぐことができる。   In the example shown in FIG. 20, the stopper 72 shown in FIG. 19B is combined with the spring member 50 shown in FIG. 13 of the first embodiment. According to this, the rotation range of the rotation part 51 can be regulated by the stopper 72. Further, even if the spring member 50 having the rotation part 51 having a central angle of 180 degrees or less is employed, and the rotation part 51 is positioned vertically downward with respect to the shaft part 40, the spring member 50 remains in the shaft part 40. Can be prevented from falling off.

（第３実施形態）
本実施形態に係るカードエッジコネクタ１０は、対をなすばね部材５０ａ，５０ｂにおいて、各固定部５２ｂ，５３ｂの配置に特徴がある。 (Third embodiment)
The card edge connector 10 according to the present embodiment is characterized by the arrangement of the fixing portions 52b and 53b in the spring members 50a and 50b that make a pair.

第１実施形態では、図６に示すように、同じ回動部５１に連結された２つの脚部５２,５２の固定部５２ｂ，５３ｂが、配列方向においてほぼ同じ位置とされ、対をなすばね部材５０ａ，５０ｂにおいて、一方のばね部材５０ａの固定部５２ｂ，５３ｂと他方のばね部材５０ｂの固定部５２ｂ，５３ｂとが配列方向においてずれて設けられる例を示した。   In the first embodiment, as shown in FIG. 6, the fixed portions 52 b and 53 b of the two leg portions 52 and 52 connected to the same rotating portion 51 are at substantially the same position in the arrangement direction, and form a pair of springs. In the members 50a and 50b, an example is shown in which the fixing portions 52b and 53b of one spring member 50a and the fixing portions 52b and 53b of the other spring member 50b are shifted in the arrangement direction.

これに対し、図２１（ａ）に展開図を示すばね部材５０は、展開状態でクランク形状となっている。そして、固定状態で、図２１（ｂ）に示すように、ばね部材５０ａの固定部５２ｂ，５３ｂ（ともに実線で図示）を結んでなる第１仮想直線と、ばね部材５０ｂの固定部５２ｂ，５３ｂ（ともに破線で図示）を結んでなる第２仮想直線とが、幅方向に垂直な平面（深さ方向及び配列方向に沿う平面）において交差する。   On the other hand, the spring member 50 shown in a developed view in FIG. 21A has a crank shape in the developed state. In the fixed state, as shown in FIG. 21B, the first imaginary straight line connecting the fixing portions 52b and 53b (both shown by solid lines) of the spring member 50a and the fixing portions 52b and 53b of the spring member 50b. A second virtual straight line formed by connecting both (shown by broken lines) intersects in a plane perpendicular to the width direction (a plane along the depth direction and the arrangement direction).

このようなばね部材５０（５０ａ，５０ｂ）を採用すると、配列方向において、固定部５２ｂ同士を異なる位置、固定部５３ｂ同士を異なる位置としながらも、回路基板１１０の変形を抑制することができる。   When such a spring member 50 (50a, 50b) is employed, deformation of the circuit board 110 can be suppressed while the fixing portions 52b are located at different positions and the fixing portions 53b are located at different positions in the arrangement direction.

なお、第１仮想直線と第２仮想直線とが交差するようなばね部材５０としては、例えば図２２（ａ）〜（ｃ）に示すコイル状のばね部材５０ａ，５０ｂを採用しても良い。コイル状のばね部材５０とは、回動部５１が中心角３６０度より大きい範囲で軸部４０周りに延びたものである。このようなばね部材５０を採用すると、中心角が３６０度未満のばね部材５０に比べてばね力を稼ぐことができる。また、回動部５１に対する脚部５２，５３の連結端５２ａ，５３ａ位置の自由度を向上することができる。   In addition, as the spring member 50 in which the first virtual line and the second virtual line intersect, for example, coiled spring members 50a and 50b shown in FIGS. 22A to 22C may be employed. The coiled spring member 50 is a member in which the rotating portion 51 extends around the shaft portion 40 in a range where the central angle is larger than 360 degrees. If such a spring member 50 is employ | adopted, a spring force can be earned compared with the spring member 50 whose center angle is less than 360 degree | times. Moreover, the freedom degree of the connection ends 52a and 53a position of the leg parts 52 and 53 with respect to the rotation part 51 can be improved.

また、配列方向において、ばね部材５０ａが（ｎ＋１）個［ｎは正の整数］の固定部を有し、ばね部材５０ｂがｎ個の固定部を有する。そして、ばね部材５０ａの固定部間の領域１つにつき、ばね部材５０ｂの固定部が１つ対向配置される構成としても、回路基板１１０の変形を抑制できる。例えば図２３（ａ），（ｂ）に示す例では、ばね部材５０ａは、深さ方向において互いにほぼ同じ位置であり、配列方向においてずれて設けられた２本の第１脚部５２を有している。同様に、深さ方向において互いにほぼ同じ位置であり、配列方向においてずれて設けられた２本の第２脚部５３を有している。したがって、ばね部材５０ａは２個の固定部５２ｂと２個の固定部５３ｂを有している。一方、ばね部材５０ｂは、ばね部材５０ａの２つの固定部５２ｂ間の領域に、固定部５２ｂが対向配置され、ばね部材５０ａの２つの固定部５３ｂ間の領域に、固定部５３ｂが対向配置されるように構成されている。   Further, in the arrangement direction, the spring member 50a has (n + 1) [n is a positive integer] fixing portions, and the spring member 50b has n fixing portions. The deformation of the circuit board 110 can be suppressed even in a configuration in which one fixing portion of the spring member 50b is disposed opposite to each other between the fixing portions of the spring member 50a. For example, in the example shown in FIGS. 23A and 23B, the spring member 50a has two first leg portions 52 that are located at substantially the same position in the depth direction and are shifted in the arrangement direction. ing. Similarly, it has two second leg portions 53 that are substantially the same position in the depth direction and are shifted in the arrangement direction. Therefore, the spring member 50a has two fixing portions 52b and two fixing portions 53b. On the other hand, in the spring member 50b, the fixed portion 52b is disposed to face the region between the two fixed portions 52b of the spring member 50a, and the fixed portion 53b is disposed to face the region between the two fixed portions 53b of the spring member 50a. It is comprised so that.

なお、図２３（ａ），（ｂ）においては、ばね部材５０ａが（ｎ＋１）個の固定部５２ｂと（ｎ＋１）個の固定部５３ｂを有し、ばね部材５０ｂがｎ個の固定部５２ｂとｎ個の固定部５３ｂを有する例を示した。しかしながら、例えば図２４（ａ）に示すように、ばね部材５０ａが２個の固定部５２ｂと１個の固定部５３ｂを有し、ばね部材５０ｂが１個の固定部５２ｂと２個の固定部５３ｂを有する。そして、図２４（ｂ）に示すように、ばね部材５０ａの２つの固定部５２ｂ間の領域に、ばね部材５０ｂの固定部５２ｂが対向配置され、ばね部材５０ｂの２つの固定部５３ｂ間の領域に、ばね部材５０ａの固定部５３ｂが対向配置される構成としても良い。   In FIGS. 23A and 23B, the spring member 50a has (n + 1) fixing portions 52b and (n + 1) fixing portions 53b, and the spring member 50b has n fixing portions 52b. The example which has n fixing | fixed part 53b was shown. However, as shown in FIG. 24A, for example, the spring member 50a has two fixing portions 52b and one fixing portion 53b, and the spring member 50b has one fixing portion 52b and two fixing portions. 53b. Then, as shown in FIG. 24 (b), the fixed portion 52b of the spring member 50b is disposed opposite to the region between the two fixed portions 52b of the spring member 50a, and the region between the two fixed portions 53b of the spring member 50b. In addition, the fixing portion 53b of the spring member 50a may be arranged to face each other.

以上、本発明の好ましい実施形態について説明したが、本発明は上述した実施形態になんら制限されることなく、本発明の主旨を逸脱しない範囲において、種々変形して実施することが可能である。   The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

本実施形態では、溝部２１がハウジング２０における基板側部２２の側面２０ｂに開口する例を示した。しかしながら、例えば図２５に示すように、回路基板１１０が挿入配置される溝部（収納空間）が、側面２０ｂに開口せず先端面２０ａのみに開口する有底孔２４であり、該有底孔２４の壁面に軸部４０が設けられた構成を採用することもできる。すなわち、有底孔２４内に少なからずばね部材５０が配置される構成を採用することもできる。図２５に示す有底孔２４は、ハウジング２０における複数の端子３０を保持する中央部分で回路基板１１０の厚さに応じた幅とされ、配列方向において中央部分を挟む両端部分で中央部分よりも幅が広くなっている。そして、両端部分における壁面から、軸部４０（４０ａ，４０ｂ）が配列方向に沿って突起している。図２５では、ハウジング２０の中央部分側の壁面に軸部４０が設けられている。そして、各軸部４０（４０ａ，４０ｂ）にばね部材５０（５０ａ，５０ｂ）が取り付けられている。この構成では、回路基板１１０の端部を、ハウジング２０の有底孔２４の空間内に収容することができる。なお、図２５では、軸部４０をハウジング２０の中央部分側の壁面に設ける例を示したが、該壁面と対向する壁面に設けることもできる。また、ハウジング２０を、例えば図２５に破線で示す位置での分割構造とすると、有底孔２４の内壁に軸部４０を有し、有底孔２４内にばね部材５０が収容された構成を形成しやすくなる。   In the present embodiment, an example in which the groove portion 21 opens on the side surface 20 b of the substrate side portion 22 in the housing 20 has been shown. However, for example, as shown in FIG. 25, the groove portion (storage space) in which the circuit board 110 is inserted and disposed is a bottomed hole 24 that does not open on the side surface 20 b but opens only on the front end surface 20 a. It is also possible to adopt a configuration in which the shaft portion 40 is provided on the wall surface. That is, it is possible to employ a configuration in which the spring member 50 is arranged in the bottomed hole 24. The bottomed hole 24 shown in FIG. 25 has a width corresponding to the thickness of the circuit board 110 in the central portion that holds the plurality of terminals 30 in the housing 20, and is wider than the central portion at both end portions sandwiching the central portion in the arrangement direction. The width is wide. And the axial part 40 (40a, 40b) protrudes along the sequence direction from the wall surface in both ends. In FIG. 25, the shaft portion 40 is provided on the wall surface on the central portion side of the housing 20. And the spring member 50 (50a, 50b) is attached to each axial part 40 (40a, 40b). In this configuration, the end of the circuit board 110 can be accommodated in the space of the bottomed hole 24 of the housing 20. In addition, although the example which provides the axial part 40 in the wall surface of the center part side of the housing 20 was shown in FIG. 25, it can also be provided in the wall surface facing this wall surface. Further, when the housing 20 has a divided structure at a position indicated by a broken line in FIG. 25, for example, the shaft portion 40 is provided on the inner wall of the bottomed hole 24 and the spring member 50 is accommodated in the bottomed hole 24. Easy to form.

本実施形態では、複数の端子３０の接触部３１の両端側において、一対のばね部材５０ａ，５０ｂがそれぞれ設けられる例を示した。しかしながら、両端それぞれにおいて複数対のばね部材５０ａ，５０ｂが設けられる構成としても良い。その際、配列方向において複数対のばね部材５０ａ，５０ｂが配置されても良いし、深さ方向において複数対のばね部材５０ａ，５０ｂが配置されても良い。   In the present embodiment, an example in which a pair of spring members 50 a and 50 b are provided on both end sides of the contact portions 31 of the plurality of terminals 30 has been described. However, it is good also as a structure by which multiple pairs of spring members 50a and 50b are provided in each of both ends. At that time, a plurality of pairs of spring members 50a and 50b may be arranged in the arrangement direction, or a plurality of pairs of spring members 50a and 50b may be arranged in the depth direction.

ばね部材５０（軸部４０）は、配列方向において複数の端子３０の接触部３１（接触部３１と回路基板１１０の電極との接続部）が間に位置するように、複数の接触部３１の両端側であって少なくとも溝部２１に対し幅方向における同一側にそれぞれ設けられれば良い。したがって、例えば図２６に示すように、回路基板１１０の一面側のみに軸部４０及びばね部材５０を設け、回路基板の他方の面側を、ハウジング２０に一体的に設けた支持部２５にて支持する構成を採用することもできる。この構成では、支持部２５に回路基板１１０が接触すると、深さ方向において回路基板１１０の位置が決定される。このような支持部２５は、図２５に示す有底孔２４にも適用することができる。   The spring member 50 (shaft portion 40) includes a plurality of contact portions 31 such that contact portions 31 (connection portions between the contact portions 31 and the electrodes of the circuit board 110) of the plurality of terminals 30 are positioned in the arrangement direction. It is only necessary to provide both ends on at least the same side in the width direction with respect to the groove 21. Therefore, for example, as shown in FIG. 26, the shaft portion 40 and the spring member 50 are provided only on one surface side of the circuit board 110, and the other surface side of the circuit board is provided by the support portion 25 provided integrally with the housing 20. A supporting structure can also be adopted. In this configuration, when the circuit board 110 comes into contact with the support portion 25, the position of the circuit board 110 is determined in the depth direction. Such a support part 25 can also be applied to the bottomed hole 24 shown in FIG.

また、図２７に示す例では、回路基板１１０の一面側のみに軸部４０及びばね部材５０を設け、回路基板の他方の面側を、ケース１２０に一体的に設けた支持部１２２にて支持する構成となっている。なお、図２７に示す構成は、ハウジング２０に溝部２１が設けられ、ハウジング２０の外に、軸部４０及びばね部材５０が設けられる構成において採用することができる。   In the example shown in FIG. 27, the shaft portion 40 and the spring member 50 are provided only on one surface side of the circuit board 110, and the other surface side of the circuit board is supported by the support portion 122 provided integrally with the case 120. It is the composition to do. The configuration shown in FIG. 27 can be adopted in a configuration in which the groove portion 21 is provided in the housing 20 and the shaft portion 40 and the spring member 50 are provided outside the housing 20.
