Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of a card connector commonly used for two kinds of cards having lengths different from each other wherein two cards can not be inserted with almost identical insertion force because a contact for a short card is pressed down against spring force, and then the insertion force of the long card becomes large when the long card is inserted. <P>SOLUTION: A slider 12 for ejection is divided into a front side slider 10 and a backside slider 11 along a card insertion direction. The long card 3 makes the backside slider 11 follow and move alone after passing through the front slider 10, and the short card 2 makes the backside slider 11 and front side slider follow and move integrally. A lateral jointing plate 10c extended toward a lower side of the contact 6 for the short card, serving as a fulcrum of elastic movement is arranged. A sufficient spring force necessary for electrically connecting the short card to an electrode is obtained when inserting the short card, while the spring force is reduced when inserting the long card by making an effective length L of a spring for the contact 6 for the short card at the time of inserting the long card longer than that at the time of inserting of the short card. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Japanese Patent Application No. 2003-49488

本発明が解決しようとする課題は、長さの異なる２種類のカードに共用できるカードコネクタでは、長いカードを挿入した場合に、コンタクト押し下げ機構により短いカード用コンタクトを押し下げるため、長いカードの挿入力（挿入抵抗）が短いカードに比べて大きくなり、両カードを略同じ挿入力で装着することができない点にある。 The problem to be solved by the present invention is that, in a card connector that can be shared by two types of cards having different lengths, when a long card is inserted, the contact for pushing down the short card is pushed down by the contact push-down mechanism. The (insertion resistance) is larger than that of a short card, and both cards cannot be mounted with substantially the same insertion force.

課題を解決するための本発明の手段は、第１のカードと第１のカードより長さが長く横幅が狭い第２のカードとのサイズの異なる２種類のカードが挿入可能なハウジング内に、第１のカードの電極と接触させて電気的に接続させる片持ち支持の板バネからなる第１コンタクトと、第２のカードの電極と接触させて電気的に接続させる片持ち支持の板バネからなる第２コンタクトを、カード挿入方向に沿って手前側と奥側に前後２列に備えると共に、カード挿抜方向に摺動するイジェクト用のスライダを備えるカードコネクタにおいて、スライダをカード挿入方向に沿って手前側の前スライダと奥側の後スライダの２つに分割形成し、前スライダは第１コンタクトの下側に張設されてこの弾性変位支点を兼ねる横連結板により一体に連結される左右のカード挿入ガイドを有し、第２のカード挿入時には第２のカードが左右のカード挿入ガイドの間を通過して後スライダを単独で追従移動させると共に、左右のカード挿入ガイドには第１のカードの左右側部を所定長さだけ挿抜自在に嵌合させる左右のカード挿入ガイド溝が形成され、第１のカード挿入時には第１のカードが前後スライダを一体的に追従移動させるように構成し、第１コンタクトの弾性変位支点から自由端までのバネ有効長を前スライダの横連結板により第１のカード挿入時よりも第２のカード挿入時に長くすることを特徴とする。 The means of the present invention for solving the problem includes a first card and a housing into which two types of cards different in size between a first card and a second card having a longer width and a smaller width can be inserted. From a first contact made of a cantilevered leaf spring to be in contact with and electrically connected to the electrode of the first card, and from a cantilevered leaf spring to be in contact with and electrically connected to the electrode of the second card In the card connector, the second contact is provided in two rows in the front and back sides along the card insertion direction, and includes a slider for ejection that slides in the card insertion / removal direction. A front slider on the near side and a rear slider on the back side are divided into two, and the front slider is stretched below the first contact and is integrally connected by a horizontal connecting plate that also serves as an elastic displacement fulcrum. The right card insertion guide has a right card insertion guide. When the second card is inserted, the second card passes between the left and right card insertion guides, and the rear slider is independently moved. The left and right card insertion guide grooves are formed so that the left and right side portions of the card can be inserted and removed by a predetermined length, and the first card moves the front and rear sliders integrally following the insertion of the first card. The effective length of the spring from the elastic displacement fulcrum of the first contact to the free end is made longer when the second card is inserted than when the first card is inserted by the lateral connecting plate of the front slider.

本発明によれば、第１のカード挿入時には第１コンタクトのバネ有効長を縮めて第１のカードの電極との電気接続に必要な十分なバネ圧を得る一方で、第２のカード挿入時には第１コンタクトのバネ有効長を第１のカード挿入時よりも長くしてバネ圧を下げるので、両カードを略同じ挿入力で装着することができる。 According to the present invention, when the first card is inserted, the effective spring length of the first contact is shortened to obtain a sufficient spring pressure necessary for electrical connection with the electrode of the first card, while the second card is inserted. Since the spring effective length of the first contact is made longer than that when the first card is inserted and the spring pressure is lowered, both cards can be mounted with substantially the same insertion force.

また、本発明では、前スライダの横連結板よりカード挿入方向に沿って奥側にも別の横連結板を平行に設け、第１のカード挿入時には奥側の横連結板により第１コンタクトの自由端部を支持し、第１コンタクトを手前側の横連結板とで２点支持することで、バネ圧を可変にする第１コンタクトを第１のカードの電極に確実に電気接続することができる。 Further, in the present invention, another horizontal connecting plate is provided in parallel on the back side along the card insertion direction from the horizontal connecting plate of the front slider, and when the first card is inserted, the first contact is connected by the back side connecting plate. By supporting the free end and supporting the first contact with the front lateral connecting plate at two points, the first contact that makes the spring pressure variable can be reliably electrically connected to the electrode of the first card. it can.

そして、図６〜図８に示す如く、前スライダ１０の前横連結板１０ｃは第１コンタクト６の基部６ａの下側に張設され、第１のコンタクト６の弾性変位支点を兼ねており、カード未挿入時には基部６ａの前端部下面が当接する位置（図６に示す位置）にあり、第１のカード挿入時には前スライダ１０が初期位置からカード挿入方向に押し込まれカード装着位置に移動することで、基部６ａの後端部下面が当接する位置（図７に示す位置）に移動する一方、第２のカード挿入時には前スライダ１０が初期位置から移動しないことで、カード未挿入時と同様に基部６ａの前端部下面が当接する位置（図８に示す位置）に保持されるもので、第１コンタクト６の弾性変位支点から自由端の接点６ｃまでのバネ有効長Ｌを前スライダ１０の前横連結板１０ｃにより第１のカード挿入時よりも第２のカード挿入時に長くするように構成している（Ｌ２＜Ｌ１）。 6 to 8, the front horizontal connecting plate 10c of the front slider 10 is stretched under the base 6a of the first contact 6, and also serves as an elastic displacement fulcrum of the first contact 6. When the card is not inserted, the lower surface of the front end of the base portion 6a is in a contact position (position shown in FIG. 6). When the first card is inserted, the front slider 10 is pushed from the initial position in the card insertion direction and moves to the card mounting position. Thus, while the front slider 10 does not move from the initial position when the second card is inserted, it moves to the position where the lower surface of the rear end of the base portion 6a abuts (the position shown in FIG. 7). It is held at the position where the lower surface of the front end of the base portion 6a contacts (the position shown in FIG. 8), and the effective spring length L from the elastic displacement fulcrum of the first contact 6 to the contact 6c of the free end is set in front of the front slider 10. Horizontal connecting plate Than when the first card insertion configured to increase upon insertion second cards by 0c (L2 <L1).

また、前スライダ１０の後横連結板１０ｄは第１コンタクト６の接片部６ｂの長さより長い間隔を設けて前横連結板１０ｃの後方に平行に張設され、カード未挿入時には接片部６ｂの下方位置（図６に示す位置）にあり、第１のカード挿入時には接片部６ｂの下方から後方に外れる位置（図７に示す位置）に移動する一方、第２のカード挿入時にはカード未挿入時と同様に接片部６ｂの下方位置（図８に示す位置）に保持される。 Further, the rear horizontal connecting plate 10d of the front slider 10 is stretched in parallel to the rear of the front horizontal connecting plate 10c with a longer interval than the length of the contact piece 6b of the first contact 6, and when the card is not inserted, the contact piece. 6b is located at a lower position (position shown in FIG. 6), and when the first card is inserted, it moves to a position (position shown in FIG. 7) that is disengaged from the lower side of the contact piece 6b. It is held at a lower position (position shown in FIG. 8) of the contact piece 6b as in the non-insertion.

さらに、前スライダ１０には前後横連結板１０ｃ，１０ｄ介して各第１コンタクト６の基部６ａの間に張設する複数の隔壁１０ｉを設け、各隔壁１０ｉの上面により左右カード挿入ガイド１０ａ，１０ｂの間にボディ底板４ａの上面と面一になるカード支持底面１０ｊを形成すると共に、各隔壁１０ｉの間に各第１コンタクト６の基部６ａを挿通させるコンタクト収容溝１０ｋを形成し、第２のカード挿入時に第２のカード３により各第１コンタクト６の接片部６ｂを各コンタクト収容溝１０ｋの内側に押し下げるように構成している。 Further, the front slider 10 is provided with a plurality of partition walls 10i extending between the base portions 6a of the first contacts 6 via the front and rear horizontal connecting plates 10c and 10d, and the left and right card insertion guides 10a and 10b are formed on the upper surface of each partition wall 10i. A card support bottom surface 10j that is flush with the upper surface of the body bottom plate 4a is formed, and a contact receiving groove 10k through which the base portion 6a of each first contact 6 is inserted is formed between the partition walls 10i, and the second When the card is inserted, the contact piece 6b of each first contact 6 is pushed down to the inside of each contact receiving groove 10k by the second card 3.

次に、上記カードコネクタ１の動作を説明する。図１，図６に示す如く、コネクタ１はカード未挿入時、イジェクト機構９は前後スライダ１０，１１がイジェクトバネ１３の付勢力により左右カード挿入ガイド１０ａ，１０ｂの前端が左右カード挿入口ガイド４ｅ，４ｆの後端に突き当たり、その左カード挿入ガイド１０ａの後端に後スライダ１１の前端が接合する初期位置に復帰保持され、左右カード挿入ガイド溝１０ｅ，１０ｆが左右カード挿入口ガイド溝４ｇ，４ｈの後端に連通接続されると共に、カム溝１７の起点部１７ａにカムピン１８の前端折り曲げ部が嵌入された初期状態（イジェクト状態）になっている。また、この初期状態では前スライダ１０の前横連結板１０ｃが第１コンタクト６の基部６ａの前端部を支えるので、第１コンタクト６は基部６ａの前端部から接片部６ｂの後端の接点６ｃまでの部分が有効になるが、このときのバネ有効長Ｌ１ではバネ機能は殆ど消失されることになる。 Next, the operation of the card connector 1 will be described. As shown in FIGS. 1 and 6, when the card is not inserted into the connector 1, the eject mechanism 9 has the front and rear sliders 10 and 11 urged by the eject spring 13 so that the front ends of the left and right card insertion guides 10a and 10b are left and right card insertion slot guides 4e. 4f hits the rear end of the left card insertion guide 10a and is held back to the initial position where the front end of the rear slider 11 is joined to the rear end of the left card insertion guide 10a, and the left and right card insertion guide grooves 10e and 10f are connected to the left and right card insertion slot guide grooves 4g, 4 h is in communication with the rear end, and an initial state (eject state) in which the bent portion of the front end of the cam pin 18 is fitted into the starting point portion 17 a of the cam groove 17. In this initial state, the front horizontal connecting plate 10c of the front slider 10 supports the front end portion of the base portion 6a of the first contact 6, so that the first contact 6 is a contact point from the front end portion of the base portion 6a to the rear end of the contact piece portion 6b. The portion up to 6c becomes effective, but the spring function is almost lost at the effective spring length L1 at this time.

そして、図２，図３，図７に示す如く、第１のカード２が正規挿入姿勢でボディ４のカード挿入口部５における左右カード挿入口ガイド４ｅ，４ｆの左右カード挿入口ガイド溝４ｇ，４ｈの間から挿入されると、第１のカード２の先端部が前スライダ１０における左右カード挿入ガイド１０ａ，１０ｂの左右カード挿入ガイド溝１０ｅ，１０ｆの間に挿入されて行き、第１のカード２の先端が左カード挿入ガイド溝１０ｅの内側に突出している連結ピン１４の前端を通過するとき、第１のカード２の先端左角部で連結ピン１４の前端を外側に押し退けてノッチ１５ａに押し込み、第１のカード２の先端が連結ピン１４の前端を通過した以降は、第１のカード２の左側面で連結ピン１４の前端の左カード挿入ガイド溝１０ｅの内側への復帰が規制されてノッチ１５ａに係合保持され、前後スライダ１０，１１が連結ピン１４により左カード挿入ガイド１０ａの後端に後スライダ１１を接合した状態で一体連結される。また、第１のカード２はその先端が連結ピン１４の前端を通過した後、その先端左右角部が左右カード挿入ガイド溝１０ｅ，１０ｆの後端に達したとき左右の係合面１０ｇ，１０ｈに突き当たり、これ以降、前後スライダ１０，１１が一体的に第１のカード２の挿入に追従移動し、第１のカード２によるカードイジェクト機構９のプッシュイン／プッシュアウト動作を可能にする。すなわち、図２に示す状態から第１のカード２を押し込むと、左右係合面１０ｇ，１０ｈが後方へ押圧され、前後スライダ１０，１１が一体的に第１のカード２の押し込みに追従移動し、イジェクトバネ１３の付勢力に抗して初期位置からボディ４の奥側へと押し込まれ、後スライダ１１の後端がボディ後側壁４ｄに突き当たる最押し込み位置へと移動する。この時点で、第１のカード２の押し込みを解除すると、前後スライダ１０，１１は一体にイジェクトバネ１３の付勢力により最押し込み位置からイジェクト方向へ押し戻される。この前後スライダ１０，１１の初期位置からの一連の動作によりカムピン１８の前端折り曲げ部がカム溝１７の起点部１７ａから往路１７ｂを経て係止部１７ｃに導入係止され、図３に示す如く、前後スライダ１０，１１のイジェクト方向への移動が最押し込み位置より少し手前のカード装着位置で規制され、ボディ４に対して前後スライダ１０，１１が一体的にカード装着位置にてロックされる。これにより、前スライダ１０における左右カード挿入ガイド１０ａ，１０ｂの左右カード挿入ガイド溝１０ｅ，１０ｆの間に嵌め込まれている第１のカード２の先端部下面の各電極が各第１コンタクト６の接点６ｃに乗り上がり接触して電気的に接続され、カード装着状態になる。 2, 3 and 7, when the first card 2 is in the normal insertion posture, the left and right card insertion slot guide grooves 4g of the left and right card insertion slot guides 4e and 4f in the card insertion slot 5 of the body 4 are provided. When inserted from between 4h, the leading end of the first card 2 is inserted between the left and right card insertion guide grooves 10e and 10f of the left and right card insertion guides 10a and 10b in the front slider 10, and the first card When the leading end of 2 passes through the front end of the connecting pin 14 protruding inside the left card insertion guide groove 10e, the front end of the connecting pin 14 is pushed outward at the left end of the leading end of the first card 2 to the notch 15a. After the first card 2 is pushed and the front end of the first card 2 passes the front end of the connecting pin 14, the return of the front end of the connecting pin 14 to the inside of the left card insertion guide groove 10e on the left side of the first card 2 is restricted. Which is held in engagement notch 15a is, front and rear sliders 10, 11 are integrally connected in a state of bonding the rear slider 11 to the rear end of the left card insertion guide 10a by a connecting pin 14. Further, after the front end of the first card 2 passes through the front end of the connecting pin 14, when the left and right corners of the front end reach the rear ends of the left and right card insertion guide grooves 10e and 10f, the left and right engagement surfaces 10g and 10h Thereafter, the front and rear sliders 10 and 11 integrally move following the insertion of the first card 2 to enable the push-in / push-out operation of the card ejection mechanism 9 by the first card 2. That is, when the first card 2 is pushed in from the state shown in FIG. 2, the left and right engaging surfaces 10g and 10h are pushed backward, and the front and rear sliders 10 and 11 integrally move following the pushing of the first card 2. Against the urging force of the eject spring 13, it is pushed from the initial position to the back side of the body 4, and moves to the most pushed position where the rear end of the rear slider 11 abuts against the body rear side wall 4 d. At this point, when the pushing of the first card 2 is released, the front and rear sliders 10 and 11 are integrally pushed back from the most pushed position to the ejecting direction by the urging force of the ejecting spring 13. As a result of a series of operations from the initial position of the front and rear sliders 10 and 11, the bent portion of the front end of the cam pin 18 is introduced and locked to the locking portion 17c from the starting point portion 17a of the cam groove 17 through the forward path 17b, as shown in FIG. The movement of the front and rear sliders 10 and 11 in the ejecting direction is restricted at the card mounting position slightly before the most depressed position, and the front and rear sliders 10 and 11 are integrally locked to the body 4 at the card mounting position. As a result, the electrodes on the lower surface of the front end of the first card 2 fitted between the left and right card insertion guide grooves 10e and 10f of the left and right card insertion guides 10a and 10b in the front slider 10 are contact points of the first contacts 6. It rides on 6c, contacts and is electrically connected, and enters the card mounting state.

上記のカード装着時、前スライダ１０の初期位置からカード装着位置への移動に伴い、第１コンタクト６の基部６ａを支えている前横連結板１０ｃも後方に移動するので、第１コンタクト６のバネ有効長Ｌが縮められる。そして、図７に示す如く、前スライダ１０がカード装着位置に達したときには、前横連結板１０ｃが第１コンタクト６の基部６ａの後端部を支えるので、第１コンタクト６は接片部６ｂのみが有効になり、このときの有効長Ｌ２により最大のバネ圧が得られるので、各第１コンタクト６の接点６ｃは装着状態の第１のカード２の電極との電気接続に十分なバネ圧（接触圧）で接触することになる。 When the card is mounted, the front horizontal connecting plate 10c supporting the base 6a of the first contact 6 also moves rearward as the front slider 10 moves from the initial position to the card mounting position. The spring effective length L is shortened. Then, as shown in FIG. 7, when the front slider 10 reaches the card mounting position, the front horizontal connecting plate 10c supports the rear end portion of the base portion 6a of the first contact 6, so that the first contact 6 has the contact piece portion 6b. Since the maximum spring pressure is obtained by the effective length L2 at this time, the contact 6c of each first contact 6 has a spring pressure sufficient for electrical connection with the electrode of the mounted first card 2. (Contact pressure) will contact.

上記のカード装着状態で第１のカード２の押し込みを行うことにより、前記係合面１０ｇ，１０ｈが後方へ押圧され、前後スライダ１０，１１は一体にイジェクトバネ１３の付勢力に抗してカード装着位置から再び最押し込み位置へと移動する。この動作によりカムピン１８の前端折り曲げ部がカム溝１７の係止部１７ｃから離脱して復路１７ｄに導入され、前後スライダ１０，１１のイジェクト方向への移動規制が解除される（一体の前後スライダ１０，１１のロックが解除される）。この時点で、第１のカード２の押し込みを解除することにより、前後スライダ１０，１１は一体にイジェクトバネ１３の付勢力により最押し込み位置からイジェクト方向へ押し戻され、初期位置へと復帰し、図２に示す如く、第１のカード２がイジェクトされて挿入初期位置で保持される。挿入初期位置にイジェクトされた第１のカード２はボディ４のカード挿入口部５から突出している端部を指で摘んで引抜くことによりボディ４から抜去ることができ、図１に示す如く、コネクタ１はカード未挿入状態になる。 When the first card 2 is pushed in with the card mounted, the engagement surfaces 10g and 10h are pressed backward, and the front and rear sliders 10 and 11 are integrally resisted against the urging force of the eject spring 13. It moves from the mounting position to the push-in position again. By this operation, the bent portion at the front end of the cam pin 18 is detached from the locking portion 17c of the cam groove 17 and introduced into the return path 17d, and the movement restriction in the eject direction of the front and rear sliders 10 and 11 is released (the integrated front and rear slider 10). , 11 is released). At this time, by releasing the pushing of the first card 2, the front and rear sliders 10 and 11 are integrally pushed back from the most pushed position to the ejected direction by the urging force of the eject spring 13, and returned to the initial position. As shown in FIG. 2, the first card 2 is ejected and held at the initial insertion position. The first card 2 ejected to the initial insertion position can be removed from the body 4 by grasping the end protruding from the card insertion slot 5 of the body 4 with a finger and pulling it out, as shown in FIG. The connector 1 is not inserted into the card.

上記のカードイジェクト時、前スライダ１０のカード装着位置から初期位置への復帰に伴い、第１コンタクト６の基部６ａを支えている前横連結板１０ｃも前方に移動するので、第１コンタクト６のバネ有効長Ｌが延ばされる。そして、図６に示す如く、前スライダ１０が初期位置に復帰したときには、上記のように前横連結板１０ｃが第１コンタクト６の基部６ａの前端部を支えるので、第１コンタクト６は基部６ａの前端部から接片部６ｂの後端の接点６ｃまでの部分が有効になり、バネ機能が殆ど消失されるバネ有効長Ｌ１に戻される。また、第１のカード２がボディ４のカード挿入口部５から引抜れることにより連結ピン１４の前端がノッチ１５ａから離脱して左カード挿入ガイド溝１０ｅの内側へ復帰し、連結ピン１４による前後スライダ１０，１１の一体連結が解除され、後スライダ１１が単独で移動可能になる。 At the time of the above-described card ejection, as the front slider 10 returns from the card mounting position to the initial position, the front horizontal connecting plate 10c supporting the base portion 6a of the first contact 6 also moves forward. The spring effective length L is extended. Then, as shown in FIG. 6, when the front slider 10 returns to the initial position, the front lateral connecting plate 10c supports the front end portion of the base portion 6a of the first contact 6 as described above, so that the first contact 6 has the base portion 6a. The portion from the front end of the contact piece 6b to the contact 6c at the rear end of the contact piece 6b becomes effective, and is returned to the spring effective length L1 at which the spring function is almost lost. Further, when the first card 2 is pulled out from the card insertion slot 5 of the body 4, the front end of the connection pin 14 is detached from the notch 15 a and returns to the inside of the left card insertion guide groove 10 e. The integral connection of the sliders 10 and 11 is released, and the rear slider 11 can move independently.

一方、図４，図５，図１１に示す如く、第２のカード３は第１のカード２より横幅が狭いので、ボディ４のカード挿入口部５における左右カード挿入口ガイド４ｅ，４ｆの間から正規挿入姿勢で挿入でき、その先端部が前スライダ１０における左右カード挿入ガイド１０ａ，１０ｂの間に挿入される。このため、第２のカード３は連結ピン１４による前後スライダ１０，１１の一体連結を解除したまま、前スライダ１０を追従移動させることなく、左右カード挿入口ガイド１０ａ，１０ｂの間を通過し、後スライダ１１の側方まで挿入され、第２のカード３の先端左側の角落とし部３ａが後スライダ１１の係合面１１ａに突き当たり、これ以降、後スライダ１１が単独で第２のカード３の挿入に追従移動し、第２のカード３によるカードイジェクト機構９のプッシュイン／プッシュアウト動作を可能にする。すなわち、図４に示す状態から第２のカード３を押し込むと、係合面１１ａが後方へ押圧され、後スライダ１１が第２のカード３の押し込みに追従移動し、イジェクトバネ１３の付勢力に抗して初期位置からボディ４の奥側へと押し込まれ、後端がボディ後側壁４ｄに突き当たる最押し込み位置へと移動する。この時点で、第２のカード３の押し込みを解除すると、後スライダ１１はイジェクトバネ１３の付勢力により最押し込み位置からイジェクト方向へ押し戻される。この後スライダ１１の初期位置からの一連の動作によりカムピン１８の前端折り曲げ部がカム溝１７の起点部１７ａから往路１７ｂを経て係止部１７ｃに導入係止され、図５に示す如く、後スライダ１１のイジェクト方向への移動が最押し込み位置より少し手前の第１のカード挿入時と同じカード装着位置で規制され、ボディ４に対して後スライダ１１がカード装着位置にてロックされる。これにより、第２のカード３の先端部下面の各電極が各第２コンタクト７の接点７ｃに乗り上がり接触して電気的に接続され、カード装着状態になる。 On the other hand, as shown in FIGS. 4, 5, and 11, the second card 3 has a narrower width than the first card 2, and therefore, between the left and right card insertion slot guides 4 e and 4 f in the card insertion slot 5 of the body 4. From the right and left card insertion guides 10 a and 10 b in the front slider 10. For this reason, the second card 3 passes between the left and right card insertion slot guides 10a and 10b without moving the front slider 10 along with the integrated connection of the front and rear sliders 10 and 11 by the connecting pin 14 being released. Inserted to the side of the rear slider 11, the corner drop portion 3 a on the left end of the second card 3 hits the engagement surface 11 a of the rear slider 11, and thereafter, the rear slider 11 alone becomes the second card 3. Following the insertion, the push-in / push-out operation of the card ejection mechanism 9 by the second card 3 is enabled. That is, when the second card 3 is pushed from the state shown in FIG. 4, the engaging surface 11 a is pushed backward, and the rear slider 11 moves following the pushing of the second card 3, and the urging force of the eject spring 13 is applied. It is pushed against the back side of the body 4 from the initial position, and moves to the most pushed position where the rear end abuts against the body rear side wall 4d. At this time, when the pushing of the second card 3 is released, the rear slider 11 is pushed back in the ejecting direction from the most pushed position by the urging force of the eject spring 13. Thereafter, a series of operations from the initial position of the slider 11 causes the front end bent portion of the cam pin 18 to be introduced and locked to the locking portion 17c from the starting portion 17a of the cam groove 17 through the forward path 17b, and as shown in FIG. 11 in the eject direction is restricted at the same card mounting position as when the first card is inserted slightly before the most depressed position, and the rear slider 11 is locked to the body 4 at the card mounting position. As a result, the electrodes on the lower surface of the front end of the second card 3 ride on and come into contact with the contacts 7c of the second contacts 7, and the card is mounted.

上記のカード装着時、図１１に示す如く、第２のカード３は前スライダ１０における左右カード挿入ガイド１０ａ，１０ｂの間を通過するとき、第２のカード３の下面で各第１コンタクト６の自由端の接点６ｃを下方に押圧して接片部６ｂを各コンタクト収容溝１０ｋの内側に押し下げながら通過し、この押し下時の摩擦力とこれ以降の第２のカード３の下面と各第１コンタクト６の接点６ｃとの摩擦力が第２のカード３の挿入抵抗になるが、第２のカード挿入時には第２のカード３の挿入に後スライダ１１のみが単独で追従移動し、前スライダ１０は追従移動することなく初期位置に保持されているので、前横連結板１０ｃも移動することなく第１コンタクト６の基部６ａの前端部を支えたままになり、第１コンタクト６のバネ有効長Ｌが初期状態のバネ有効長Ｌ１に保持される。これにより、第１コンタクト６のバネ機能は殆ど消失され、バネ圧は第２のカード３の挿入に殆ど影響を及ぼさない程度にまで極端に小さくなっているので、第２のカード３も第１のカード２と略同じ挿入力で装着でき、両カード２，３の挿入力に差を生じるのを低減又は防止できる。 When the card is mounted, as shown in FIG. 11, when the second card 3 passes between the left and right card insertion guides 10a and 10b in the front slider 10, the lower surface of the second card 3 is connected to the first contact 6 by the lower surface. The contact 6c at the free end is pressed downward to pass through the contact piece 6b while being pushed down to the inside of each contact receiving groove 10k. The frictional force between the first contact 6 and the contact 6c becomes the insertion resistance of the second card 3, but when the second card is inserted, only the rear slider 11 moves following the insertion of the second card 3 alone, and the front slider Since 10 is held at the initial position without following movement, the front end of the base 6a of the first contact 6 is supported without moving the front lateral connecting plate 10c, and the spring of the first contact 6 is effective. Length L is It is held in a spring effective length L1 phases state. As a result, the spring function of the first contact 6 is almost lost, and the spring pressure is extremely reduced to such an extent that the insertion of the second card 3 is hardly affected. The card 2 can be mounted with substantially the same insertion force as that of the card 2, and a difference in insertion force between the cards 2 and 3 can be reduced or prevented.

上記のカード装着状態で第２のカード３の押し込みを行うことにより、前記係合面１１ａが後方へ押圧され、後スライダ１１はイジェクトバネ１３の付勢力に抗してカード装着位置から再び最押し込み位置へと移動する。この動作によりカムピン１８の前端折り曲げ部がカム溝１７の係止部１７ｃから離脱して復路１７ｄに導入され、後スライダ１１のイジェクト方向への移動規制が解除される（後スライダ１１のロックが解除される）。この時点で、第２のカード３の押し込みを解除することにより、後スライダ１１はイジェクトバネ１３の付勢力により最押し込み位置からイジェクト方向へ押し戻され、前端が初期位置に保持されている前スライダ１０の左カード挿入ガイド１０ａの後端に接合する初期位置へと復帰し、図４に示す如く、第２のカード３がイジェクトされて挿入初期位置で保持される。挿入初期位置にイジェクトされた第２のカード３はボディ４のカード挿入口部５から突出している端部を指で摘んで引抜くことによりボディ４から抜去ることができ、図１に示す如く、コネクタ１はカード未挿入状態になる。 When the second card 3 is pushed in the above-described card mounting state, the engagement surface 11a is pressed backward, and the rear slider 11 is pushed again from the card mounting position against the urging force of the eject spring 13 again. Move to position. By this operation, the bent portion of the front end of the cam pin 18 is detached from the locking portion 17c of the cam groove 17 and introduced into the return path 17d, and the movement restriction of the rear slider 11 in the eject direction is released (the lock of the rear slider 11 is released). ) At this time, by releasing the pushing of the second card 3, the rear slider 11 is pushed back from the most pushed position to the ejecting direction by the urging force of the eject spring 13, and the front slider 10 whose front end is held at the initial position. The left card insertion guide 10a returns to the initial position where it is joined to the rear end, and the second card 3 is ejected and held at the initial insertion position as shown in FIG. The second card 3 ejected to the initial insertion position can be removed from the body 4 by pulling out the end protruding from the card insertion slot 5 of the body 4 with a finger, as shown in FIG. The connector 1 is not inserted into the card.

以上のように、第１のカード２と第１のカード２より長さが長く横幅が狭い第２のカード３とのサイズの異なる２種類のカードが挿入可能なハウジングであるボディ４内に、第１のカード２の電極と接触させて電気的に接続させる片持ち支持の板バネからなる第１コンタクト６と、第２のカード３の電極と接触させて電気的に接続させる片持ち支持の板バネからなる第２コンタクト７を、カード挿入方向に沿って手前側と奥側に前後２列に備えると共に、カード挿抜方向に摺動するイジェクト用のスライダ１２を備えるカードコネクタにおいて、スライダ１２をカード挿入方向に沿って手前側の前スライダ１０と奥側の後スライダ１１の２つに分割形成し、前スライダ１０は第１コンタクト６の下側に張設されてこの弾性変位支点を兼ねる横連結板１０ｃにより一体に連結される左右のカード挿入ガイド１０ａ，１０ｂを有し、第２のカード挿入時には第２のカード３が左右のカード挿入ガイド１０ａ，１０ｂの間を通過して後スライダ１１を単独で追従移動させると共に、左右のカード挿入ガイド１０ａ，１０ｂには第１のカード２の左右側部を所定長さだけ挿抜自在に嵌合させる左右のカード挿入ガイド溝１０ｅ，１０ｆが形成され、第１のカード挿入時には第１のカード２が前後スライダ１０，１１を一体的に追従移動させるように構成し、第１コンタクト６の弾性変位支点から自由端までのバネ有効長Ｌを前スライダ１０の横連結板１０ｃにより第１のカード挿入時よりも第２のカード挿入時に長くすることで、第１のカード挿入時には第１コンタクト６のバネ有効長を縮めて第１のカード２の電極との電気接続に必要な十分なバネ圧を得る一方で、第２のカード挿入時には第１コンタクト６のバネ有効長を第１のカード挿入時よりも長くしてバネ圧を下げるので、両カード２，３を略同じ挿入力で装着することができる。 As described above, in the body 4 which is a housing into which two types of cards having different sizes can be inserted, the first card 2 and the second card 3 having a longer length and a narrower width than the first card 2. A first contact 6 made of a cantilever-supported leaf spring that is brought into contact with and electrically connected to the electrode of the first card 2; and a cantilever-supported that is brought into contact with and electrically connected to the electrode of the second card 3. In a card connector provided with second contacts 7 made of leaf springs in two front and rear rows along the card insertion direction in the front and back sides, and with an eject slider 12 that slides in the card insertion / removal direction, the slider 12 A front slider 10 on the front side and a rear slider 11 on the back side are divided into two along the card insertion direction, and the front slider 10 is stretched below the first contact 6 and serves as an elastic displacement fulcrum. The left and right card insertion guides 10a and 10b are integrally connected by a connecting plate 10c. When the second card is inserted, the second card 3 passes between the left and right card insertion guides 10a and 10b and the rear slider 11 is inserted. The left and right card insertion guides 10a and 10b are respectively formed with left and right card insertion guide grooves 10e and 10f for fitting the left and right side portions of the first card 2 so as to be freely inserted and removed by a predetermined length. When the first card is inserted, the first card 2 is configured to integrally move the front and rear sliders 10 and 11 so that the effective spring length L from the elastic displacement fulcrum of the first contact 6 to the free end is set to the front slider. By using the 10 lateral connecting plates 10c, the spring effective length of the first contact 6 is reduced when the first card is inserted by making it longer when the second card is inserted than when the first card is inserted. Thus, while obtaining a sufficient spring pressure necessary for electrical connection with the electrode of the first card 2, the spring effective length of the first contact 6 is set longer than that when the first card is inserted when the second card is inserted. Since the spring pressure is lowered, both cards 2 and 3 can be mounted with substantially the same insertion force.

また、スライダ１２を第１のカード２の挿入に追従移動する前スライダ１０と第２のカード３の挿入に追従移動する後スライダ１１の二つに分割形成したが、これら前後スライダ１０，１１と単一のイジェクトバネ１３と単一のロック機構１６により両カード２，３に共用できるプッシュイン／プッシュアウト型のカードイジェクト機構９を構成しているので、すなわち、両カード２，３ごとに独立したプッシュイン／プッシュアウト型のカードイジェクト機構を備える必要がないので、サイズの異なる２種類のカード２，３に共用できるカードコネクタ１の構造を簡潔にでき、コストも低減できる。 The slider 12 is divided into two parts, a front slider 10 that moves following the insertion of the first card 2 and a rear slider 11 that moves following the insertion of the second card 3. The push-in / push-out type card eject mechanism 9 that can be shared by both the cards 2 and 3 is constituted by the single eject spring 13 and the single lock mechanism 16, that is, each card 2 and 3 is independent. Since it is not necessary to provide the push-in / push-out type card ejection mechanism, the structure of the card connector 1 that can be shared by the two types of cards 2 and 3 having different sizes can be simplified and the cost can be reduced.

図９〜図１１に示す如く、第１コンタクト６の接片部６ｂに接点６ｃからさらに後方に延設する延長部６ｅを設け、第１のカード挿入時に第１コンタクト６の接片部６ｂの下方より後方に外れる位置に移動する後横連結板１０ｄにより前記延長部６ｅの端部を支え、基部６ａの後端部を支えている前横連結板１０ｃとで第１コンタクト６の接片部６ｂを前後端２点で支持するように構成している。すなわち、カード未挿入時及び第２のカード挿入時に前スライダ１０の後横連結板１０ｃにより１点支持される第１コンタクト６を第１のカード２が挿入されてカード装着位置に達したときに２点支持に切り替えて支持するように構成している。 As shown in FIGS. 9 to 11, the contact piece 6b of the first contact 6 is provided with an extension 6e extending further rearward from the contact 6c, and the contact piece 6b of the first contact 6 is inserted when the first card is inserted. The contact portion of the first contact 6 is supported by the front horizontal connecting plate 10c that supports the end of the extension 6e by the rear horizontal connecting plate 10d that moves to a position that deviates backward from below, and supports the rear end of the base 6a. 6b is configured to be supported at two front and rear ends. That is, when the first card 2 is inserted through the first contact 6 supported at one point by the rear lateral connecting plate 10c of the front slider 10 when the card is not inserted and when the second card is inserted, the card mounting position is reached. It is configured to support by switching to two-point support.

上記のように前スライダ１０の前横連結板１０ｃよりカード挿入方向に沿って奥側にも別の後横連結板１０ｄを平行に設け、第１のカード挿入時には奥側の後横連結板１０ｄにより第１コンタクト６の自由端（延長部６ｅの端部）を支持し、第１コンタクト６を手前側の前横連結板１０ｃとで２点支持することで、前スライダ１０の前横連結板１０ｃによりバネ圧を可変にする第１コンタクト６を第１のカード２の電極に確実に電気接続することができる。 As described above, another rear horizontal connecting plate 10d is provided in parallel on the back side along the card insertion direction from the front horizontal connecting plate 10c of the front slider 10, and when the first card is inserted, the rear side rear connecting plate 10d is provided. To support the free end of the first contact 6 (the end of the extension 6e), and the first contact 6 is supported at two points by the front lateral coupling plate 10c on the front side, thereby the front lateral coupling plate of the front slider 10 The first contact 6 that makes the spring pressure variable by 10 c can be reliably electrically connected to the electrode of the first card 2.
