Description

本発明は、ｍｉｃｒｏＳＤカード等のメモリカード用のコネクタ及び該メモリカード用コネクタを備えた携帯端末に関する。   The present invention relates to a connector for a memory card such as a microSD card and a portable terminal including the memory card connector.

メモリカード用コネクタは、メモリカードを挿脱可能に受け入れる収納部を備えるハウジングと、収納部内をメモリカードと一緒にスライドするスライダと、を備えている。収納部の底面には、収納部に挿入したメモリカードの端子と電気的に導通可能な多数のコンタクトが設けてある。また、スライダはメモリカードの端子とハウジングのコンタクトが非接触となる非導通位置と、端子とコンタクトが接触する導通位置とに移動可能である。
この種のコネクタには一般的に、スライダを上記導通位置に一時的に保持することにより、メモリカードの端子とハウジングのコンタクトの導通状態を維持するハートカム機構が設けてある。 The memory card connector includes a housing having a storage portion that removably receives the memory card, and a slider that slides in the storage portion together with the memory card. On the bottom surface of the storage unit, there are provided a number of contacts that can be electrically connected to the terminals of the memory card inserted into the storage unit. Further, the slider is movable to a non-conductive position where the contact of the memory card and the contact of the housing are not in contact and a conductive position where the terminal and the contact are in contact.
In general, this type of connector is provided with a heart cam mechanism that maintains a conductive state between a memory card terminal and a housing contact by temporarily holding a slider in the conductive position.

ハートカム機構は、カムバーと、カムバーの一端部を回転可能に支持する支持用凹部と、カムバーの他端部が相対移動可能に係合するハートカム溝と、を備えている。
ハートカム溝はカムバーの他端部が係合しトレースするため、ハートカム溝は出来るだけ深く形成するのが好ましい。しかし、近年はコネクタに対する低背化の要求が厳しいため、スライダにハートカム溝を形成する場合はハートカム溝の深さを大きくするのが難しい。
そこで特許文献１では、スライダの上面にカムバーの一端部を回転可能に支持する支持用凹部を形成すると共に、ハウジングの底面にカムバーの他端部が移動可能に係合するハートカム溝を形成し、さらにハウジングの天井面を塞ぐカバー部材に切り起こし成形した板ばねの自由端部でカムバーをハウジングの底面側に押圧することによりカムバーの他端部がハートカム溝から浮き上がり脱落しないようにしている（係合が解除されないようにしている）。
このようにハウジング側にハートカム溝を形成すれば、ハートカム溝を深く形成しても、スライダの上面にハートカム溝を形成する場合に比べてコネクタ全体を低背化できる。
特開２００６−１９０３０号公報 The heart cam mechanism includes a cam bar, a support recess that rotatably supports one end of the cam bar, and a heart cam groove that engages the other end of the cam bar so as to be relatively movable.
Since the heart cam groove engages and traces the other end of the cam bar, the heart cam groove is preferably formed as deep as possible. However, in recent years, there is a strict demand for a low profile connector, and when the heart cam groove is formed on the slider, it is difficult to increase the depth of the heart cam groove.
Therefore, in Patent Document 1, a support recess for rotatably supporting one end portion of the cam bar is formed on the upper surface of the slider, and a heart cam groove is formed on the bottom surface of the housing so that the other end portion of the cam bar is movably engaged. Furthermore, the other end of the cam bar is lifted from the heart cam groove so that it does not fall off by pressing the cam bar to the bottom side of the housing with the free end of the leaf spring that is cut and raised in the cover member that closes the ceiling surface of the housing. So that it is not released.)
By forming the heart cam groove on the housing side in this way, the overall height of the connector can be reduced even when the heart cam groove is formed deeper than when the heart cam groove is formed on the upper surface of the slider.
JP 2006-19030 A

カムバーの他端部がハートカム溝から浮き上がらないようにするためには、ハートカム溝に近い側の端部であるカムバーの他端部（または他端部近傍）を板ばねによってハウジングの底面側に押圧するのが理想的である。
しかし、特許文献１ではスライダがスライドするとカムバーもハウジング及びカバー部材に対して相対移動するため、スライダの位置が変化すると板ばねの自由端部とカムバーの相対位置が変化してしまう。そのため、スライダの位置によっては板ばねの自由端部が、カムバーの中央部や一端部側を押圧してしまう。 In order to prevent the other end of the cam bar from floating from the heart cam groove, the other end (or the vicinity of the other end) of the cam bar, which is the end near the heart cam groove, is pressed against the bottom surface of the housing by a leaf spring. Ideally.
However, in Patent Document 1, when the slider slides, the cam bar also moves relative to the housing and the cover member. Therefore, when the position of the slider changes, the relative position between the free end of the leaf spring and the cam bar changes. Therefore, depending on the position of the slider, the free end portion of the leaf spring presses the center portion or one end portion side of the cam bar.

さらに、メモリカードと一緒にスライダを非導通位置から導通位置側にスライドさせるときは、スライダの初期動作を円滑にし、さらにハートカム溝の摩耗やハウジングの底面部の反り返りを小さく抑えるために、板ばねによる押圧力を機能が満足する程度に小さくするのが理想的である。反面、スライダを導通位置に確実に保持したり（カムバーの他端部をハートカム溝の位置Ｅに係合させる）、カムバーの他端部がハートカム溝の段差を乗り越えるときに明確なクリックを得るためには、板ばねによる押圧力を大きくする必要がある。
しかし、特許文献１ではスライダの位置に拘わらず板ばねからカムバーにほぼ一定の押圧力を及ぼしており、板ばねからカムバーに適切に押圧力を及ぼしているとは言えない。 Furthermore, when the slider is slid together with the memory card from the non-conductive position to the conductive position, the leaf spring is used to facilitate the initial operation of the slider, and to minimize the wear of the heart cam groove and the warping of the bottom surface of the housing. It is ideal to reduce the pressing force due to the pressure to such an extent that the function is satisfactory. On the other hand, to securely hold the slider in the conductive position (to engage the other end of the cam bar with the position E of the heart cam groove) or to obtain a clear click when the other end of the cam bar gets over the step of the heart cam groove For this, it is necessary to increase the pressing force by the leaf spring.
However, in Patent Document 1, regardless of the position of the slider, a substantially constant pressing force is applied from the leaf spring to the cam bar, and it cannot be said that the pressing force is appropriately applied from the leaf spring to the cam bar.

本発明の目的は、スライダが非導通位置と導通位置のいずれに位置するときも付勢手段がカムバーのハートカム溝と近い部分を押圧でき、しかもスライダの位置に応じてカムバーに適切な付勢力を及ぼすことが可能なメモリカード用コネクタ及び該メモリカード用コネクタを備えた携帯端末を提供することにある。   The object of the present invention is to allow the biasing means to press the portion of the cam bar close to the heart cam groove when the slider is in either the non-conductive position or the conductive position, and to apply an appropriate biasing force to the cam bar according to the position of the slider. An object of the present invention is to provide a memory card connector capable of exerting and a portable terminal including the memory card connector.

本発明のメモリカード用コネクタは、メモリカードを挿脱可能な収納部、及び該収納部に挿入したメモリカードの端子と電気的に導通するコンタクトを有するハウジングと、上記メモリカードと一緒に上記収納部内をスライドし、上記端子と上記コンタクトが非接触となる非導通位置と、上記端子とコンタクトが接触する導通位置とに移動可能なスライダと、一端部が上記スライダに支持されると共に他端部が収納部の上記底面に形成したハートカム溝に係合し、該ハートカム溝との係合位置を変化させることにより上記スライダの上記導通位置への保持及び該保持の解除を行うカムバーと、上記スライダが上記非導通位置に位置するとき上記カムバーの上記他端部または他端部近傍を上記底面側に押圧する第１押圧部と、上記スライダが上記導通位置に位置するとき上記他端部または他端部近傍を上記底面側に押圧する第２押圧部とを有する付勢手段と、を備えることを特徴としている。   The memory card connector according to the present invention includes a housing part into which a memory card can be inserted and removed, a housing having a contact electrically connected to a terminal of the memory card inserted into the housing part, and the housing together with the memory card. A slider that slides within the section and is movable to a non-conductive position where the terminal and the contact are not in contact with each other and a conductive position where the terminal and the contact are in contact; and one end is supported by the slider and the other end Engaging with a heart cam groove formed on the bottom surface of the storage portion, and changing the engagement position with the heart cam groove to hold the slider at the conduction position and release the holding, and the slider A first pressing portion that presses the other end portion of the cam bar or the vicinity of the other end portion toward the bottom surface when the slider is located at the non-conducting position; The other end or the other end portion near when located in the conducting position is characterized in that it comprises a biasing means and a second pressing portion for pressing to the bottom side.

上記第２押圧部の付勢力が第１押圧部の付勢力より大きいのが好ましい。   The urging force of the second pressing part is preferably larger than the urging force of the first pressing part.

上記付勢手段が片持ちばねであり、上記第１押圧部が上記片持ちばねの自由端部であり、上記第２押圧部が上記片持ちばねの長手方向の中間部であるのが好ましい。   Preferably, the urging means is a cantilever spring, the first pressing portion is a free end portion of the cantilever spring, and the second pressing portion is an intermediate portion in the longitudinal direction of the cantilever spring.

上記第２押圧部が、上記板ばねの自由状態において支持端部と自由端部を結ぶ直線より上記底面側に突出する中間突出部であるのが好ましい。   It is preferable that the second pressing portion is an intermediate protruding portion that protrudes toward the bottom surface side from a straight line connecting the support end portion and the free end portion in the free state of the leaf spring.

上記ハウジングの天井面を開放し、該ハウジングの天井面を金属製のカバー部材で塞ぎ、該カバー部材に上記片持ちばねを切り起こし成形するのが好ましい。   It is preferable that the ceiling surface of the housing is opened, the ceiling surface of the housing is closed with a metal cover member, and the cantilever spring is cut and formed on the cover member.

本発明のメモリカード用コネクタは、例えば携帯端末に実装可能である。   The memory card connector of the present invention can be mounted on, for example, a portable terminal.

本発明によると、コネクタに適用する場合（請求項１から５）も携帯端末（請求項６）に適用する場合も、スライダが非導通位置に位置するときは付勢手段の第１押圧部が、カムバーのハートカム溝と対向する部分である他端部または他端部近傍をハウジングの底面側に押圧し、かつ、スライダが導通位置に位置するときは付勢手段の第２押圧部がカムバーの他端部または他端部近傍をハウジングの底面側に押圧する。従って、スライダの位置によらずカムバーの他端部がハートカム溝から浮き上がり脱落するのを確実に防止できる。   According to the present invention, when applied to the connector (Claims 1 to 5) and when applied to the portable terminal (Claim 6), the first pressing portion of the urging means is applied when the slider is located at the non-conductive position. The other end of the cam bar facing the heart cam groove or the vicinity of the other end is pressed toward the bottom surface of the housing, and when the slider is located at the conducting position, the second pressing portion of the urging means is The other end or the vicinity of the other end is pressed toward the bottom surface of the housing. Therefore, it is possible to reliably prevent the other end portion of the cam bar from being lifted from the heart cam groove and falling off regardless of the position of the slider.

請求項２記載の発明によると、付勢手段は第１押圧部がカムバーに当接するときに比べて第２押圧部がより強い付勢力（押圧力）を発生するため、スライダの初期動作時（非導通位置から導通位置側へのスライド動作）においては、ハートカム溝の削れやハウジングの底面部の反り返りを効果的に防止できるとともに円滑な操作が可能となる。
また、スライダが導通位置に位置するときには、ハートカム溝とカムバーによってスライダを導通位置に確実に保持することが可能になる。さらに、スライダが導通位置近傍を移動しカムバーの他端部がハートカム溝の段差を乗り越えるとき、操作者に明確なクリック感を与えることが可能になる。 According to the second aspect of the present invention, the biasing means generates a stronger biasing force (pressing force) than that when the first pressing portion abuts against the cam bar. In the sliding operation from the non-conducting position to the conducting position), it is possible to effectively prevent the heart cam groove from being scraped and the bottom surface portion of the housing from being warped, and to perform a smooth operation.
Further, when the slider is positioned at the conducting position, the slider can be reliably held at the conducting position by the heart cam groove and the cam bar. Further, when the slider moves in the vicinity of the conduction position and the other end of the cam bar climbs over the step of the heart cam groove, a clear click feeling can be given to the operator.

請求項３の発明によると、板ばねの支持端部から第１押圧部（自由端部）までの距離が支持端部から第２押圧部（中間部）までの距離より長いので、第２押圧部がカムバーに当接するとき、付勢手段は第１押圧部がカムバーに当接するときに比べてより強い付勢力（押圧力）を発生する。
従って、第２押圧部が第１押圧部より強い付勢力を発生する簡単な構造の付勢手段が得られる。 According to the invention of claim 3, since the distance from the supporting end of the leaf spring to the first pressing portion (free end) is longer than the distance from the supporting end to the second pressing portion (intermediate portion), the second pressing When the portion abuts against the cam bar, the urging means generates a stronger urging force (pressing force) than when the first pressing portion abuts against the cam bar.
Therefore, an urging means having a simple structure in which the second pressing portion generates a stronger urging force than the first pressing portion can be obtained.

請求項４の発明によると、第２押圧部が板ばねの支持端部と自由端部を結ぶ直線より底面側に突出する中間突出部を有するので、非導通位置、導通位置を問わず、カムバーと板ばねは当接する部位以外の部分でも近接するため、カムバーが外乱によって振動や衝撃を受け不要な傾きが生じたりしても（イレギュラーな挙動をしても）、カムバーを安定して押圧することが可能となる。
また、板ばねの長さを長くすることができるため、コネクタが軽薄短小化されてもばね性を確保でき、安定してカムバーを押圧することが可能となる。 According to the invention of claim 4, since the second pressing portion has the intermediate projecting portion projecting to the bottom surface side from the straight line connecting the supporting end portion and the free end portion of the leaf spring, the cam bar can be used regardless of the non-conducting position or the conducting position. Since the leaf springs are close to each other than the part where they abut, even if the cam bar is subject to vibrations or shocks due to disturbances, an unnecessary tilt occurs (even if it behaves irregularly), the cam bar is stably pressed. It becomes possible to do.
Further, since the length of the leaf spring can be increased, the spring property can be ensured even when the connector is lightened, thinned, and the cam bar can be stably pressed.

請求項５記載の発明によると、片持ちばねが金属製のカバー部材に一体に形成されるため、コネクタに対する片持ちばねの相対的な位置が安定するとともに小型・低背のコネクタでありながら優れたばね性を得ることができる。また、部品点数の削減と組立等の製造コストの低減も可能となる。   According to the invention of claim 5, since the cantilever spring is integrally formed with the metal cover member, the relative position of the cantilever spring with respect to the connector is stabilized, and it is excellent in spite of being a small and low-profile connector. A springiness can be obtained. In addition, it is possible to reduce the number of parts and manufacturing costs such as assembly.

請求項６記載の発明によると、メモリカードを挿抜する際の操作感や作業性・安定性に優れ、メモリカード保持が確実である携帯端末を提供することができる。   According to the sixth aspect of the present invention, it is possible to provide a portable terminal that is excellent in operation feeling and workability / stability when a memory card is inserted / removed, and that holds the memory card reliably.

As shown in detail in FIGS. 8 and 9, the heart cam groove 30 is a groove having a number of steps recessed around the heart-shaped convex portion 31, and includes an initial engagement portion 32 that forms the front end portion thereof, A push-in passage portion 33 located on the right side of the convex portion 31, a holding portion 34 located at the rear end portion of the heart-shaped convex portion 31, and a return passage portion 35 located on the left side of the heart-shaped convex portion 31. is doing.
The mounting groove 37 that is recessed in the front-rear direction intermediate portion of the left side wall 17 has a pressed portion 38 that protrudes toward the right side in the vicinity of the rear end portion, and further has a protrusion 39a at the rear end portion of the outer surface. The second switch terminal 39 is fitted and fixed. Furthermore, a first switch terminal (detection means) 36 is integrally provided on the left side wall 17 in a manner located outside the second switch terminal (detection means) 39. Both the tail portion (not shown) of the first switch terminal 36 and the tail portion 39b of the second switch terminal 39 are soldered to the detection circuit pattern on the substrate.

合成樹脂材による成形品であるスライダ４０の下面には、スライダ案内溝２９と同幅かつスライダ案内溝２９より前後長が短い案内突部４１が突設してある。案内突部４１はスライダ案内溝２９に摺動可能に嵌合しているので、スライダ４０はスライダ案内溝２９に沿ってコネクタ１０の底面上をスライド可能である。スライダ４０の左端部にはメモリカード係合部４２が設けてあり、メモリカード係合部４２の前端部の左側面は前後方向及び左右方向に対して略ばね支持軸４５°の角度で傾斜する傾斜面４３となっている。
一方、スライダ４０の右端部にはばね収容空間２６内に位置するばね支持部４４が設けてあり、ばね支持部４４の前面及び後面には互いに同軸をなすと共にばね支持軸２７及びばね支持軸２８とも同軸をなすばね支持軸４５とばね支持軸４６が突設してある。ばね支持軸４５とばね支持軸２７には圧縮コイルばねＳ１の前後両端部がそれぞれ嵌っており、さらにばね支持軸２８とばね支持軸４６には圧縮コイルばねＳ２の前後両端部がそれぞれ嵌っている。圧縮コイルばねＳ１の付勢力は圧縮コイルばねＳ２の付勢力より大きいので、スライダ４０に圧縮コイルばねＳ１、圧縮コイルばねＳ２以外の外力を掛けない状態においては、圧縮コイルばねＳ１と圧縮コイルばねＳ２の強さの差による前向きの付勢力（以下、「圧縮コイルばねＳ１による前向きの付勢力」と呼ぶ）によって、スライダ４０は案内突部４１の前端がスライダ案内溝２９の前端面に接触する非導通位置（図４及び図５の位置）に位置する。
また、スライダ４０の上面には平面視略Ｌ字形の取付溝４７が凹設してあり、スライダ４０の前端部には突起４８が突設してある。この取付溝４７には、前端部に弾性係合部５１を有するロック金具５０の略Ｌ字形をなす後端部５２が嵌合しており、ロック金具５０の前端部の右側面が突起４８に弾性接触している。さらに、スライダ４０の後端部の上面には支持用凹部４９が凹設してある。 A guide projection 41 having the same width as the slider guide groove 29 and a shorter front-rear length than the slider guide groove 29 is provided on the lower surface of the slider 40, which is a molded product made of a synthetic resin material. Since the guide protrusion 41 is slidably fitted in the slider guide groove 29, the slider 40 can slide on the bottom surface of the connector 10 along the slider guide groove 29. A memory card engagement portion 42 is provided at the left end portion of the slider 40, and the left side surface of the front end portion of the memory card engagement portion 42 is inclined at an angle of approximately 45 ° with respect to the front-rear direction and the left-right direction. An inclined surface 43 is formed.
On the other hand, a spring support portion 44 located in the spring accommodating space 26 is provided at the right end portion of the slider 40, and the front and rear surfaces of the spring support portion 44 are coaxial with each other, and the spring support shaft 27 and the spring support shaft 28. A spring support shaft 45 and a spring support shaft 46 that are coaxial with each other are projected. The front and rear end portions of the compression coil spring S1 are fitted to the spring support shaft 45 and the spring support shaft 27, respectively, and the front and rear end portions of the compression coil spring S2 are fitted to the spring support shaft 28 and the spring support shaft 46, respectively. . Since the urging force of the compression coil spring S1 is larger than the urging force of the compression coil spring S2, the compression coil spring S1 and the compression coil spring S2 are in a state where no external force other than the compression coil spring S1 and the compression coil spring S2 is applied to the slider 40. Due to the forward biasing force (hereinafter referred to as “forward biasing force due to the compression coil spring S1”) due to the difference in strength between the slider 40 and the slider 40, the front end of the guide protrusion 41 contacts the front end surface of the slider guide groove 29. It is located at the conducting position (position shown in FIGS. 4 and 5).
A mounting groove 47 having a substantially L-shape in plan view is formed on the upper surface of the slider 40, and a projection 48 is provided on the front end of the slider 40. The mounting groove 47 is fitted with a rear end portion 52 having a substantially L shape of a lock fitting 50 having an elastic engagement portion 51 at the front end, and the right side surface of the front end portion of the lock fitting 50 is formed on the protrusion 48. Elastic contact. Further, a support recessed portion 49 is formed on the upper surface of the rear end portion of the slider 40.

カムバー６０は、ハウジング１５の底面に形成したハートカム溝３０とスライダ４０を連係する部材である。即ち、カムバー６０はその前後両端部に下向きに屈曲する前端係合突部（一端部）６１と後端係合突部（他端部）６２を有しており、前端係合突部６１はスライダ４０の支持用凹部４９に回転可能に支持され、後端係合突部６２はハート形凸部３１に相対移動可能に係合している。
このようにスライダ４０、圧縮コイルばねＳ１、圧縮コイルばねＳ２及びカムバー６０を収納するハウジング１５の天井面は、金属板のプレス成形品であるカバー部材７０によって覆われている。カバー部材７０の側壁には複数の係合孔７１が形成してあり、さらにカバー部材７０の前端には下向きの嵌合突部７２が突設してある。そして、各係合孔７１にハウジング１５の対応する係合突起２２を嵌合し、嵌合突部７２をハウジング１５の前側端部壁２５に凹設した嵌合凹部２３に嵌合することにより、カバー部材７０のハウジング１５からの脱落を防止している。また、カバー部材７０の左右の側壁の下端部にはそれぞれ２つのテール部７３が突設してあり、これらテール部７３は上記基板の接地パターンに半田付けしてある。
図１、図２、図１０及び図１１に示すように、カバー部材７０の上面の後端の右側角部近傍には、上記プレス成形によってカバー部材７０の成形時に同時に成形した片持ち式の板ばね７４が設けてある。板ばね７４の中間部には、自由状態において自由端部（第１押圧部）７５と支持端部を結ぶ直線よりハウジング１５の底面側に位置する中間屈曲部（第２押圧部）７６が形成してある。この板ばね７４はカムバー６０を常にハウジング１５の底面側（下向き）に押圧する付勢手段である。 The cam bar 60 is a member that links the heart cam groove 30 formed on the bottom surface of the housing 15 and the slider 40. That is, the cam bar 60 has a front end engagement protrusion (one end) 61 and a rear end engagement protrusion (other end) 62 that are bent downward at both front and rear ends thereof. The rear end engaging projection 62 is engaged with the heart-shaped convex portion 31 so as to be relatively movable.
Thus, the ceiling surface of the housing 15 that houses the slider 40, the compression coil spring S1, the compression coil spring S2, and the cam bar 60 is covered with the cover member 70 that is a press-formed product of a metal plate. A plurality of engagement holes 71 are formed in the side wall of the cover member 70, and a downward fitting protrusion 72 is provided at the front end of the cover member 70. Then, by engaging the corresponding engaging protrusion 22 of the housing 15 in each engaging hole 71 and fitting the fitting protrusion 72 into the fitting recess 23 provided in the front end wall 25 of the housing 15. The cover member 70 is prevented from falling off from the housing 15. In addition, two tail portions 73 project from the lower end portions of the left and right side walls of the cover member 70, and these tail portions 73 are soldered to the ground pattern of the substrate.
As shown in FIGS. 1, 2, 10, and 11, in the vicinity of the right corner of the rear end of the upper surface of the cover member 70, a cantilever plate that is simultaneously formed when the cover member 70 is formed by the above press molding. A spring 74 is provided. In the intermediate portion of the leaf spring 74, an intermediate bent portion (second pressing portion) 76 is formed which is located on the bottom surface side of the housing 15 with respect to a straight line connecting the free end portion (first pressing portion) 75 and the supporting end portion in the free state. It is. The leaf spring 74 is a biasing means that always presses the cam bar 60 toward the bottom surface side (downward) of the housing 15.

次に以上構成のコネクタ１０にｍｉｃｒｏＳＤカードＭＣを挿脱するときの動作について説明する。
図１に示すようにコネクタ１０にｍｉｃｒｏＳＤカードＭＣを挿入していない状態においては、図５に示すようにスライダ４０は上記非導通位置に位置しており、カムバー６０の後端係合突部６２はハートカム溝３０の初期係合部３２に係合している（図４及び図５参照）。
この状態でｍｉｃｒｏＳＤカードＭＣをコネクタ１０の前面開口部から収納部１９内に挿入し後方に押し込むと、ｍｉｃｒｏＳＤカードＭＣの右側縁部の後部に形成した係合突部ＭＣ１がロック金具５０の弾性係合部５１を弾性変形させながら乗り越える。すると、図４及び図５に示すように係合突部ＭＣ１の前面をなす当接傾斜面ＭＣ２がスライダ４０の傾斜面４３に当接し、かつロック金具５０の弾性係合部５１がｍｉｃｒｏＳＤカードＭＣの右側縁部に凹設した係合凹部ＭＣ３に弾性係合するので、ｍｉｃｒｏＳＤカードＭＣがスライダ４０と一体化する。
図１０に示すように、スライダ４０が非導通位置に位置するときは、板ばね７４の自由端部７５がカムバー６０の後端部近傍を下向きに押圧しているので、自由端部７５がカムバー６０の前端部（または前端部近傍）を下向きに押圧する場合に比べて後端係合突部６２の初期係合部３２からの浮き上がりを確実に防止できる（後端係合突部６２と初期係合部３２を確実に係合させることができる）。
その一方で、板ばね７４の支持端部から自由端部７５までの距離は比較的長いので（支持端部から中間屈曲部７６までの距離より長いので）、このとき自由端部７５がカムバー６０に及ぼす付勢力はそれほど大きくはない。そのため、ｍｉｃｒｏＳＤカードＭＣをそれほど大きな力で後方に押し込まなくても、圧縮コイルばねＳ１による前向きの付勢力に抗してスライダ４０及びｍｉｃｒｏＳＤカードＭＣを後方に円滑にスライドさせることができる。さらに、このときの後端係合突部６２と初期係合部３２の間に生じる摩擦抵抗力は小さいので、初期係合部３２が摩耗したりハウジングの底面部が反り返るのを効果的に防止できる。 Next, an operation when the microSD card MC is inserted into and removed from the connector 10 having the above configuration will be described.
As shown in FIG. 1, when the microSD card MC is not inserted into the connector 10, the slider 40 is located at the non-conducting position as shown in FIG. Is engaged with the initial engagement portion 32 of the heart cam groove 30 (see FIGS. 4 and 5).
In this state, when the microSD card MC is inserted into the storage portion 19 from the front opening of the connector 10 and pushed backward, the engagement protrusion MC1 formed at the rear portion of the right edge of the microSD card MC becomes the elastic engagement of the lock fitting 50. Get over the joint 51 while elastically deforming it. Then, as shown in FIGS. 4 and 5, the contact inclined surface MC2 forming the front surface of the engaging projection MC1 contacts the inclined surface 43 of the slider 40, and the elastic engaging portion 51 of the lock fitting 50 is connected to the microSD card MC. Therefore, the microSD card MC is integrated with the slider 40.
As shown in FIG. 10, when the slider 40 is located at the non-conduction position, the free end portion 75 of the leaf spring 74 presses the vicinity of the rear end portion of the cam bar 60 downward. As compared with the case where the front end portion 60 (or the vicinity of the front end portion) is pressed downward, the rear end engaging protrusion 62 can be reliably prevented from being lifted from the initial engaging portion 32 (the rear end engaging protrusion 62 and the initial position). The engaging portion 32 can be reliably engaged).
On the other hand, the distance from the support end portion of the leaf spring 74 to the free end portion 75 is relatively long (since it is longer than the distance from the support end portion to the intermediate bent portion 76). The urging force exerted on is not so great. Therefore, the slider 40 and the microSD card MC can be smoothly slid rearward against the forward biasing force of the compression coil spring S1 without pushing the microSD card MC backward with such a large force. Further, since the frictional resistance force generated between the rear end engaging protrusion 62 and the initial engaging portion 32 at this time is small, it is possible to effectively prevent the initial engaging portion 32 from being worn and the bottom surface portion of the housing from warping. it can.

ｍｉｃｒｏＳＤカードＭＣとスライダ４０が一緒に後方にスライドし、カムバー６０の後端係合突部６２が押し込み時通過部３３を通ってハート形凸部３１の後方に位置した後にｍｉｃｒｏＳＤカードＭＣに対する後方への押圧力を解除すると、圧縮コイルばねＳ１による前向きの付勢力によりスライダ４０及びｍｉｃｒｏＳＤカードＭＣが前方に押し戻され、後端係合突部６２が保持部３４に係合することによりスライダ４０が図６及び図７に示す導通位置に保持される。スライダ４０が導通位置に位置すると、ｍｉｃｒｏＳＤカードＭＣの下面に形成した各端子（図示略）が対応するコンタクト２０の接触端部２０ａと接触し電気的に導通する。さらに、ｍｉｃｒｏＳＤカードＭＣの前端部の左側面が第２スイッチ端子３９の被押圧部３８を左側に押圧するので、突起３９ａが第１スイッチ端子３６の右側面の前端部に接触する。すると、上記基板に形成した検知用回路パターンを通してコネクタ１０を実装した電子機器（携帯電話、パーソナルコンピュータ、デジタルカメラ等）の制御部に検知信号が送られるので、該制御部がｍｉｃｒｏＳＤカードＭＣとコンタクト２０が電気的に導通したことを検知する。
図１１に示すようにスライダ４０が導通位置あるいはその近傍に位置するとき、板ばね７４の中間屈曲部７６がカムバー６０の後端部近傍を下向きに押圧するので、カムバー６０の前端部または前端部近傍を押圧する場合に比べて後端係合突部６２の初期係合部３２からの浮き上がりを確実に防止できる。
さらに、板ばね７４の支持端部から中間屈曲部７６までの距離は支持端部から自由端部７５までの距離より短いので、このとき中間屈曲部７６がカムバー６０に及ぼす付勢力はスライダ４０が非導通位置に位置するときに自由端部７５がカムバー６０に及ぼす付勢力より大きい。そのため、後端係合突部６２が押し込み時通過部３３と保持部３４の段差、あるいは保持部３４と戻り時通過部３５の段差を乗り越えるとき、操作者に明確なクリック感を与えることができる。しかも、後端係合突部６２と保持部３４は強い力で確実に係合することになるので、後端係合突部６２と保持部３４によりスライダ４０は導通位置に確実に保持される。 The microSD card MC and the slider 40 slide rearward together, and the rear end engaging projection 62 of the cam bar 60 passes through the passage portion 33 when pushed in and is positioned behind the heart-shaped convex portion 31 and then rearward with respect to the microSD card MC. When the pressing force is released, the slider 40 and the microSD card MC are pushed back forward by the forward biasing force of the compression coil spring S1, and the rear end engaging projection 62 is engaged with the holding portion 34, so that the slider 40 is shown in FIG. 6 and the conductive position shown in FIG. When the slider 40 is located at the conduction position, each terminal (not shown) formed on the lower surface of the microSD card MC comes into contact with the corresponding contact end portion 20a of the contact 20 and is electrically conducted. Furthermore, since the left side surface of the front end portion of the microSD card MC presses the pressed portion 38 of the second switch terminal 39 to the left side, the protrusion 39a contacts the front end portion of the right side surface of the first switch terminal 36. Then, since a detection signal is sent to the control unit of the electronic device (mobile phone, personal computer, digital camera, etc.) on which the connector 10 is mounted through the detection circuit pattern formed on the substrate, the control unit makes contact with the microSD card MC. It is detected that 20 is electrically conductive.
As shown in FIG. 11, when the slider 40 is positioned at or near the conducting position, the intermediate bent portion 76 of the leaf spring 74 presses the vicinity of the rear end portion of the cam bar 60 downward, so that the front end portion or front end portion of the cam bar 60 As compared with the case where the vicinity is pressed, it is possible to reliably prevent the rear end engaging protrusion 62 from being lifted from the initial engaging portion 32.
Further, since the distance from the support end portion of the leaf spring 74 to the intermediate bent portion 76 is shorter than the distance from the support end portion to the free end portion 75, the urging force exerted by the intermediate bend portion 76 on the cam bar 60 at this time is determined by the slider 40. The free end portion 75 is larger than the urging force exerted on the cam bar 60 when positioned at the non-conduction position. Therefore, when the rear end engaging projection 62 gets over the step between the passing portion 33 and the holding portion 34 when pushed in, or the step between the holding portion 34 and the passing portion 35 when returning, a clear click feeling can be given to the operator. . In addition, since the rear end engaging projection 62 and the holding portion 34 are reliably engaged with each other with a strong force, the slider 40 is reliably held at the conducting position by the rear end engaging projection 62 and the holding portion 34. .

カムバー６０の後端係合突部６２と保持部３４によってスライダ４０を導通位置に保持した状態で、スライダ４０を再度圧縮コイルばねＳ１による前向きの付勢力に抗してさらに後方に押し込み、さらにｍｉｃｒｏＳＤカードＭＣに対する後方への押圧力を解除すると、圧縮コイルばねＳ１による前向きの付勢力により後端係合突部６２が保持部３４から離れて戻り時通過部３５側に移動し、戻り時通過部３５を通って初期係合部３２の前端まで自動的に移動する。従って、スライダ４０は非導通位置に復帰し、ｍｉｃｒｏＳＤカードＭＣの端子と各コンタクト２０の接触が解除される。さらに、ｍｉｃｒｏＳＤカードＭＣの前端部の左側面が第２スイッチ端子３９の被押圧部３８から離れ、第２スイッチ端子３９の突起３９ａが第１スイッチ端子３６の右側面の前端部から離れるので、ｍｉｃｒｏＳＤカードＭＣとコンタクト２０が非導通状態になったことを上記電子機器の制御部が検知する。
このようにスライダ４０が非導通位置に復帰した後に、係合突部ＭＣ１がロック金具５０の弾性係合部５１を乗り越えるまでｍｉｃｒｏＳＤカードＭＣを前方に引き出せば、ｍｉｃｒｏＳＤカードＭＣをコネクタ１０から前方に取り出すことができる。 With the slider 40 held in the conducting position by the rear end engaging protrusion 62 and the holding portion 34 of the cam bar 60, the slider 40 is pushed back further against the forward biasing force of the compression coil spring S1, and further microSD When the rearward pressing force on the card MC is released, the rear end engaging projection 62 moves away from the holding portion 34 to the return passage portion 35 side by the forward biasing force of the compression coil spring S1, and the return passage portion. It moves automatically through 35 to the front end of the initial engaging portion 32. Accordingly, the slider 40 returns to the non-conducting position, and the contact between the terminals of the microSD card MC and each contact 20 is released. Further, the left side surface of the front end portion of the microSD card MC is separated from the pressed portion 38 of the second switch terminal 39, and the protrusion 39a of the second switch terminal 39 is separated from the front end portion of the right side surface of the first switch terminal 36. The control unit of the electronic device detects that the card MC and the contact 20 are in a non-conductive state.
After the slider 40 returns to the non-conducting position in this way, the microSD card MC is pulled forward from the connector 10 by pulling the microSD card MC forward until the engagement protrusion MC1 gets over the elastic engagement portion 51 of the lock fitting 50. It can be taken out.

以上説明したように本実施形態では、スライダ４０が非導通位置と導通位置のいずれに位置するときも、板ばね７４からカムバー６０の後端部近傍に押圧力を及ぼすので、カムバー６０の後端係合突部６２のハート形凸部３１からの浮き上がりを確実に防止できる。
しかも、スライダ４０が非導通位置に位置するときは自由端部７５からカムバー６０に比較的弱い押圧力を及ぼし、スライダ４０が導通位置に位置するときは中間屈曲部７６からカムバー６０に強い押圧力を及ぼしているので、スライダ４０の位置に応じて板ばね７４からカムバー６０に最適な強さの押圧力を及ぼすことが出来る。 As described above, in the present embodiment, a pressing force is applied from the leaf spring 74 to the vicinity of the rear end portion of the cam bar 60 when the slider 40 is located at either the non-conductive position or the conductive position. The lifting of the engaging protrusion 62 from the heart-shaped convex portion 31 can be reliably prevented.
Moreover, when the slider 40 is located at the non-conducting position, a relatively weak pressing force is exerted on the cam bar 60 from the free end portion 75, and when the slider 40 is located at the conducting position, a strong pressing force is exerted on the cam bar 60 from the intermediate bent portion 76. Therefore, it is possible to apply a pressing force having an optimum strength from the leaf spring 74 to the cam bar 60 according to the position of the slider 40.

本発明は本実施形態に限定されるものではなく、様々な変形を施しながら実施可能である。
例えば、板ばね７４の全長、板厚、幅、材質、中間屈曲部７６の位置等を変えることにより、板ばね７４からカムバー６０に及ぼす押圧力を調整することが可能である。
また、板ばね７４をカバー部材７０と一体的に形成せず別部材としてもよい。
さらに、板ばね７４を樹脂製のばねとしてもよい。この場合は、例えば、カバー部材７０を樹脂製とし、このカバー部材７０に切り起こしにより板ばね７４を一体的に設けてもよい。 The present invention is not limited to this embodiment, and can be implemented with various modifications.
For example, the pressing force exerted on the cam bar 60 from the leaf spring 74 can be adjusted by changing the overall length, the plate thickness, the width, the material, the position of the intermediate bent portion 76, and the like of the leaf spring 74.
Further, the leaf spring 74 may not be formed integrally with the cover member 70 but may be a separate member.
Further, the plate spring 74 may be a resin spring. In this case, for example, the cover member 70 may be made of resin, and the leaf spring 74 may be integrally provided by cutting and raising the cover member 70.

また、本実施形態では板ばね７４の自由端部７５と中間屈曲部７６でカムバー６０の後端部近傍を押圧しているが、自由端部７５や中間屈曲部７６でカムバー６０の後端部（後端係合突部６２の直上部分）を押圧するようにしてもよい。
さらに、板ばね７４を下方に向かって湾曲する側面視円弧状とし（中央部が最も下方に位置し、円弧状部の前端と後端を除く中間部全体が中間突出部を構成する）、スライダ４０の位置に応じて板ばね７４が前端部近傍部（第１押圧部）から後端部近傍部（第２押圧部）に位置を変えながらカムバー６０の後端部（または後端部近傍）を押圧するようにしてもよい。
さらに、板ばね７４の中間部の複数箇所に自由状態において自由端部７５と支持端部を結ぶ直線よりハウジング１５の底面側に位置する中間屈曲部を形成してもよい。図１２は板ばね７４の中間部の２箇所に２つの中間屈曲部７７、７８を形成した例である。この変形例では、スライダ４０が非導通位置に位置するとき（図１２のとき）は自由端部７５がカムバー６０の後端部近傍（または後端部）を押圧し、スライダ４０が非導通位置と導通位置の間に位置したときは中間屈曲部７７がカムバー６０の後端部近傍（または後端部）を押圧し、スライダ４０が導通位置に位置したときは中間屈曲部７８がカムバー６０の後端部近傍（または後端部）を押圧する。
また、本実施形態のコネクタ１０はｍｉｃｒｏＳＤカードＭＣ用のものであるが、その他のメモリカード（ＳＤカード、ｍｉｎｉＳＤカード、ｍｉｃｒｏＳＤカード、メモリースティック、ｘＤピクチャーカード、ＭＭＣ等）用のコネクタとして実施することは勿論可能である。 Further, in the present embodiment, the vicinity of the rear end portion of the cam bar 60 is pressed by the free end portion 75 and the intermediate bent portion 76 of the leaf spring 74, but the rear end portion of the cam bar 60 is pressed by the free end portion 75 and the intermediate bent portion 76. You may make it press (the part right above the rear-end engagement protrusion 62).
Further, the leaf spring 74 has a circular arc shape in a side view that curves downward (the central portion is located at the lowest position, and the entire intermediate portion excluding the front and rear ends of the arc-shaped portion constitutes an intermediate protrusion), and slider The rear end portion (or the vicinity of the rear end portion) of the cam bar 60 while the leaf spring 74 changes its position from the vicinity of the front end portion (first pressing portion) to the vicinity of the rear end portion (second pressing portion) according to the position 40. You may make it press.
Furthermore, intermediate bent portions positioned on the bottom surface side of the housing 15 from a straight line connecting the free end portion 75 and the support end portion in a free state may be formed at a plurality of locations in the intermediate portion of the leaf spring 74. FIG. 12 shows an example in which two intermediate bent portions 77 and 78 are formed at two locations in the intermediate portion of the leaf spring 74. In this modification, when the slider 40 is located at the non-conduction position (in FIG. 12), the free end portion 75 presses the vicinity of the rear end portion (or the rear end portion) of the cam bar 60 and the slider 40 is in the non-conduction position. The intermediate bent portion 77 presses the vicinity (or the rear end portion) of the cam bar 60 when it is positioned between the conductive position and the intermediate bent portion 78 of the cam bar 60 when the slider 40 is positioned at the conductive position.
