Description

  The present invention relates to an IC card connector that allows a plurality of different types of IC cards to be attached to and detached from a card accommodation space, and that electrically connects one mounted IC card to an electronic device.

  In electronic devices such as mobile phones, telephones, PDAs (personal digital assistance), cameras, etc., for example, a central processing unit (CPU) or an MMC (multi media card) card (trademark), SD (with integrated memory circuit) secure digital) card, memory stick (trademark) and xD-Picture Card (trademark) (hereinafter referred to as "XD card"), etc., by attaching to each electronic device via an IC card connector, Various enhancements have been made.

  The IC cards described above have different shapes. Various IC card connectors have been proposed so that these IC cards can be mounted on the above-described electronic devices and each IC card can be used.

  In order to accommodate such IC cards having different shapes, the IC card connector has a common card insertion slot, and the card accommodation space following the card insertion slot is an external contact of the IC card to be mounted. A plurality of contact rows corresponding to the pads are arranged in series in the card insertion direction. When such a configuration is provided, it is necessary to prevent damage to the contact rows that are not supported by the IC card inserted from the common card insertion slot.

  The present applicant has proposed an IC card connector as disclosed in Patent Document 1 so that contact rows arranged in a plurality of rows are not damaged by an incompatible IC card.

  The proposed IC card connector is configured so that the above-described four types of IC cards can be mounted. In this IC card connector, when a memory stick with the largest overall length (length in the insertion direction) and thickness is installed, the tip of the memory stick inserted from the card insertion slot comes into contact with the slider and rotates the slider. Let me push you down. As a result, the slider moves the contact portion of the contact for the SD card having the same thickness as the memory stick but a short total length downward. As a result, the tip of the memory stick does not interfere with the SD card contact row, and the memory stick can reach the memory stick contact row disposed in the innermost part of the card accommodation space.

  Here, the case where the SD card is mounted will be briefly described with reference to FIG. FIG. 6 is a schematic cross-sectional view of the IC card connector with the SD card attached.

  As shown in FIG. 6, the SD card 600 inserted from the card insertion slot 508 into the card accommodation space formed by the base member 510 and the cover member 520 unlocks the slider 530, and the front end of the SD card 600. Abuts against the slider 530 to move the slider 530 rearward and rotate the slider 530. Thereby, each contact 560 of the contact row corresponding to the SD card 600 protrudes upward from the slit 532 formed in the slider 530, and the contact portion 562 of each contact 560 corresponds to the SD corresponding to the further insertion of the SD card 600. Each of the pads 602 as an external contact of the card 600 is electrically contacted. In FIG. 6, reference numeral 580 denotes a memory stick contact, and 570 denotes an XD card contact.

  At this time, the eject member 540 for assisting the ejection of the inserted IC card also comes into contact with the tip of the SD card 600 and moves backward (left side in FIG. 6) as the SD card 600 is inserted, as shown in FIG. Locked in the position Although not shown, the eject member 540 is biased forward (right side in FIG. 6) by a spring member, and is provided so as to be movable in the front-rear direction along one side wall of the IC card.

  Normally, when the SD card 600 is removed, the eject member 540 is unlocked by slightly pushing in the SD card, and the eject member returns to the original front position by the biasing force of the spring member. As a result, the SD card whose tip is in contact with the eject member 540 is also discharged from the card insertion slot 508. At the same time, the slider 530 also returns to the initial position in conjunction with the movement of the eject member 540, and each contact 560 (more specifically, the contact portion 562) in the contact row is accommodated in the slit 532.

Japanese Patent Application No. 2005-106769

  By the way, in the state shown in FIG. 6, the SD card 600 can be forcibly pulled out from the IC card connector, that is, forcibly removed without adopting the above-described normal removal method. FIG. 7 shows a schematic cross-sectional view of the IC card connector in a state where the SD card is forcibly removed.

  As shown in FIG. 7, after the SD card 600 is forcibly removed, the ejector member 540 remains locked. The fact that the ejector member 540 remains locked means that the slider 530 also has moved backward as shown in FIG. 7, and the SD card contact 560 thus protrudes upward from the slit 532 of the slider 530. Is in a state. In this state, for example, when a memory stick or an SD card is inserted into the card accommodation space in a normal state, a reverse state, or a reverse state, the leading ends of these cards are contact portions of the SD card contact 560. There is a risk that the contact 560 may be deformed or buckled by directly contacting the tip of 562.

And a lock / unlock bracket that locks the movement of the slider, and the slider is locked by the lock / unlock bracket only when the second card is inserted. Is released, and moves backward and rotates against the second spring member to project the contact portions of the plurality of contacts of the second contact row upward from the slit, and An external contact of the second card can be electrically connected.

  In the IC card connector according to the present invention, the bottom wall of the base member corresponding to the second spring member preferably includes an inclined surface that descends as it goes forward, More preferably, the arc surface is convex downward.

  In the IC card connector according to the present invention, it is preferable that the slider is further provided with a locking claw that locks the step formed on the bottom wall.

  Further, in the IC card connector according to the present invention, when the first IC card is inserted, the slider is locked to the lock / unlock metal fitting at the plurality of the second contact rows. The contact portion of the contact is rotated while being accommodated in the slit, and the passage of the first IC card is allowed.

  In the IC card connector according to the present invention, in particular, the slider is biased forward by the second spring member, so that even if the inserted IC card is forcibly removed, the slider is in its original position and inclined posture. You can return to Therefore, even if any IC card is subsequently inserted into the IC card connector, the contacts in the second contact row are not deformed or buckled.

  Further, the bottom wall of the base member corresponding to the second spring member is provided with an inclined surface that descends toward the front, and the inclined surface is formed as a downwardly convex circular arc surface, so that the initial position of the slider and Make sure to return to the tilted position.

  Furthermore, no matter which of the plurality of IC cards having different shapes are inserted, there is no problem, and reliable electrical contact between the inserted IC card and the corresponding contact can be obtained.

FIG. 4 is an enlarged cross-sectional view of a main part taken along the axis of the second spring member corresponding to the portion surrounded by the circle A in FIG. FIG. 5 is a schematic cross-sectional view of the IC card connector at the same position as in FIG. 2, and shows a state after the SD card is forcibly removed from the state of FIG. In this specification, “front” refers to the top in FIG. 1, “rear” refers to the bottom in FIG. 1, “left” refers to the left in FIG. 1, and “right” refers to FIG. To the right. Further, “upper” refers to the upper side in FIG. 2 (the front side in FIG. 1), and “lower” refers to the lower side in FIG. 2 (the back side in FIG. 1).

  As shown in FIGS. 1 and 2, the IC card connector 1 includes a base member 10 made of an electrically insulative synthetic resin and a metal or a base member 10 that is combined with the base member 10 to form a card accommodation space. And a cover member 20 made of synthetic resin.

  A plurality of IC cards (in this embodiment, four types of IC cards) having different shapes such as length, width, or thickness can be attached to the IC card connector 1 according to the present invention. Cards cannot be installed at the same time. That is, the IC card connector 1 according to the present invention is configured such that only one of them is mounted when put to practical use. Accordingly, when another IC card is mounted on the IC card connector 1, the currently mounted IC card must be removed and then mounted.

  The base member 10 has a right side wall 12, a left side wall 14, and a rear side wall 16, and forms a card accommodation space together with the cover member 20 as described above. The card accommodation space is open at the front and forms a card insertion slot 8 into which an IC card is inserted. The card insertion slot 8 has a vertical height and a horizontal width so that any of a plurality of IC cards having different shapes can be inserted. Further, a guide groove or the like may be appropriately formed in the card insertion slot 8.

  In the base member 10, a plurality of contact rows are arranged in series corresponding to a plurality of IC cards having different shapes, particularly lengths. The first contact row is a contact row corresponding to the first IC card having the longest length such as a memory stick. The plurality of contacts 60 in the first contact row are arranged in parallel to the left and right side walls 12 and 14 with the contact portions 62 facing the card insertion slot, and the rear wall of the base member 10 is interposed via the fixing portions of the contacts 60. 16 is fixedly supported in a cantilever shape. The second contact row is a contact row corresponding to a second IC card having an intermediate length such as an SD card and an MMC card. The plurality of contacts 70 in the second contact row are arranged in parallel to the left and right side walls 12 and 14 with the contact portions 72 facing the card insertion slot, and the intermediate positions of the base member 10 via the fixing portions of the contacts 70. Thus, the bottom wall 18 is fixedly supported in a cantilever shape. The third contact row is a contact row corresponding to the third IC card having the shortest length such as an XD card. The plurality of contacts 80 in the third contact row are arranged in parallel with the left and right side walls 12, 14 with the contact portion 82 facing rearward, and the card on the bottom wall 12 of the base member 10 through the fixing portion of the contact 80. The portion forming the insertion slot 8 is fixedly supported in a cantilever shape. In addition, each contact 60, 70, and 80 has a contact part located above the fixed part, and the contact part can be displaced up and down like the conventional example. It has an elastic deformation part. Each contact 60, 70 and 80 also has a terminal portion connected to an external contact of the electronic device on the side opposite to the contact portion of the fixed portion.

  The IC card connector 1 further includes a slider 30. When the first IC card that is in electrical contact with the first contact row is inserted into the slider 30, the second contact row contacts the tip of the first IC card, and the contact 70 is deformed. It is a member for protecting the second contact row so as not to buckle.

  The slider 30 has a substantially rectangular shape, and, as shown in FIG. 2, a plurality of contacts 70 arranged in the second contact row at the front base end portion 31, the rear end portion 33, and the intermediate portion. The slit 32 corresponding to is provided. The slider 30 is movable on the bottom wall 12 of the base member 10 in the front-rear direction via a support shaft 37 extending in the left-right direction at the front end of the front base end portion 31 and is rotatable on the bottom wall 12. Configured.

  The slider 30 further includes a spring member support arm 38 located on the left side (upper side in FIG. 1) located below an eject member 40 described later. The spring member support arm 38 extends in parallel with the slider 30 and is formed so as to be integrated in the middle of the rear end portion 33. A support protrusion 34 is formed at the rear end of the spring member support arm 38 (see FIG. 4), and one end of the second spring member 52 that biases the slider 30 forward is the support protrusion 34. Is fixed to the rear end of the spring support arm 38. The other end of the second spring member 52 is fixed to the rear side wall 16 so as to surround the support protrusion 17 protruding from the rear side wall 16 of the base member 10. The second spring member 52 is preferably a compression coil spring, and extends from the rear side wall 16 to the support protrusion 34 via a recess 42 formed on the lower surface of an eject member 40 described later. On the lower surface of the rear end of the spring member support arm 38, there is formed a locking claw that can be locked to a step provided on the bottom wall 12 when the slider 30 moves rearward and rotates counterclockwise in the figure. Also good. With this configuration, when the corresponding second IC card is mounted and the pad, which is the external contact, is in contact with the contact 70, the return or displacement of the slider 30 by the second spring member 52 is ensured. Can be prevented.

  When the IC card is not inserted, the slider 30 has a front base end 31 front end of the slider 30 by the biasing force of the second spring member 52 via the spring member support arm 38 as shown in FIG. The support shaft 37 is pressed against the first step portion 16 formed on the bottom wall 12 formed at a predetermined position behind the third contact row (initial position of the slider 30). Further, the slider 30 is disposed so as to be inclined from the front base end portion 31 toward the rear end portion 33 (initial posture of the slider 30). Accordingly, the rear end portion 33 is located in the card accommodation space. When the slider 30 is in this state, the contact portion 72 of the contact 70 in the second contact row is accommodated in the slit 32 of the slider 30.

  In addition, the part of the bottom wall 12 of the base member 10 corresponding to the recessed part 42 of the eject member 40 in which the second spring member 52 is arranged to be extendable / contracted is a part close to the rear side wall 16 as shown in FIG. It is preferable that the height be close to the second spring member 52. Further, the bottom wall portion 12 is preferably provided with an inclined surface 12a that descends as it goes forward. The inclined surface 12a is more preferably an inclined surface having a convex arcuate surface. By providing the inclined surface 12a, as shown in FIGS. 3 and 4, the slider 30 moves rearward against the second spring member 52 as the corresponding second IC card 100 is inserted. The slider member 30 is rotated counterclockwise in the drawing, and is easily pushed down substantially horizontally. When the second IC card 100 is detached from the IC card connector 1, the second spring member 52 rotates the slider 30 in the clockwise direction in the drawing by the biasing force. As a result, the second spring member 52 returns the slider 30 to the inclined state that is the initial posture by the biasing force (returning force), and the support shaft 37 of the slider 30 abuts on the step portion 16 of the bottom wall 12. Return to the original position.

  The slider 30 is also formed with a locking projection 36 that protrudes toward the left side wall 14 at the left end thereof and toward the front. The locking projection 36 corresponds to an engagement hole 94 formed at the free end of the lock / unlock metal fitting 90, which will be described later, and can be engaged with and disengaged from the engagement hole 94.

  The IC card connector 1 further includes an eject member 40. The eject member 40 constitutes an eject mechanism that assists the ejection of the IC card inserted into the card housing space of the IC card connector 1, and the first spring member 50 causes the card ejection direction, that is, the card insertion slot 8 side. It is energized. The eject member 40 includes an abutting portion that abuts on the tip of each IC card to be inserted. In FIG. 1, the abutting portion 48 that abuts on the tip of the memory stick as the longest first IC card is provided. It is shown. In other IC cards, the contact portion is formed as a step portion in a groove for guiding each IC card formed in the eject member 40 (refer to Patent Document 1 for details).

  A heart cam 54 and a lever guide groove 56 surrounding the heart cam 54 are formed on the upper surface of the rear portion of the eject member 40. The other end of the cam lever 58 whose one end is rotatably supported by the rear wall 16 of the base member 10 slides in the lever guide groove 56 as a cam follower. The operation of the ejection mechanism composed of the ejection member 40, the first spring member 50, the heart cam, the lever guide groove 56, and the cam lever 58 has been well known before the filing of the present application. Therefore, the description is omitted here.

  The IC card connector 1 further includes a lock / unlock fitting 90. The lock / unlock metal fitting 90 normally locks the slider 30 so that it cannot move when an IC card (in this embodiment, the first card and the third card) is inserted. The lock / unlock fitting 90 is a slider only when an intermediate and wide second IC card such as an SD card or MMC card is inserted into the card housing space of the IC card connector 1. It operates to release the 30 lock state.

  The lock / unlock fitting 90 includes an elastic deformation portion 92 having an engagement hole 94 that engages with the locking projection 36 of the slider 30 at the tip portion, and a curved portion 96 that protrudes toward the card accommodation space at the intermediate portion, and A fixing portion 98 extending substantially parallel to the elastic deformation portion 92 is included. The elastic deformation portion 92 and the fixed portion 98 are connected in a substantially U shape. The lock / unlock metal fitting 90 is fixed to the left side wall 14 of the base member 10 via a fixing portion 96. The elastic deformation portion 92 of the lock / unlock metal fitting 90 is formed not only to be elastically deformed in the horizontal direction (vertical direction in FIG. 1) but also to be elastically deformable in the vertical direction (perpendicular to the paper surface in FIG. 1). The With this configuration, the slider 30 can be rotated when locked.

  The operation of the slider 30, the lock / unlock fitting 90, and the ejector member 40 accompanying the mounting of the IC card to the IC card connector 1 will be described.

  As described above, in the lock / unlock metal fitting 90, as shown in FIG. 2, the engagement hole 94 formed at the distal end portion of the elastically deforming portion 92 is normally engaged with the locking projection 36 of the slider 30. When the slider 30 is locked, the backward movement of the slider 30 is locked. However, the slider 30 can always be rotated counterclockwise.

  First, in the case of the memory stick which is the largest first IC card, this is the same as the conventional one. This will be briefly described below.

  The memory stick has a smaller width than an SD card or MMC card, which is a second IC card having an intermediate size. Therefore, even when the memory stick is inserted into the card receiving space from the card insertion slot 8 of the IC card connector 1, the side wall of the memory stick does not contact the curved portion 96 of the lock / and-lock fitting 90, and the slider 30 Remains locked. The memory stick that has pushed down the contact portion 82 of each contact 80 in the third contact row and has advanced backward contacts the front base end portion 31 of the slider 30 and rotates the slider 30 counterclockwise in FIG. When the slider 30 rotates and the rear end portion 33 of the slider 30 is pushed down, the contact 70 contacts the rear end portion 33. Therefore, the contact portion 72 of each contact 70 in the second contact row is also pushed downward while being positioned in the slit 32 of the slider 30. The memory stick reaches the first contact row without being obstructed by the second contact row, and a pad which is an external contact of the memory stick comes into contact with the contact portion 62 of the corresponding contact 60.

  On the other hand, with the insertion of the memory stick as the first IC card, the tip of the memory stick comes into contact with the contact portion 48 of the eject member 40, and the eject member 40 is moved backward against the first spring member 50. Move. When the pad of the memory stick comes into contact with the contact 60, the eject member 40 is locked with the other end of the cam lever 58 engaged with the heart cam 54.

  Next, when a wide second IC card 100 such as an SD card or an MMC card is inserted, the curved portion of the lock / unlock fitting 90 is formed on the side of the inserted second IC card 100. 96 contacts. As a result, the elastically deforming portion 92 of the lock / unlock metal fitting 90 is deformed, and the engagement hole 94 formed at the tip portion thereof is disengaged from the locking projection 36 of the slider 30 to release the locked state of the slider 30. The unlocked slider 30 is configured such that the tip of the IC card 100 to be inserted comes into contact with the front base end portion 31 thereof, so that the second spring member is directed rearward as the second IC card 100 is inserted. While moving against the urging force of 52, the second IC card 100 inserted is rotated counterclockwise in FIG. 2 and pushed down (see FIGS. 3 and 4). Thereby, the contact portion 72 of the contact 70 constrained by the rear end portion 33 of the slider 30 protrudes upward from the slit 32 of the slider 30 by the elastic force of the contact 70 itself, and is inserted as shown in FIG. The second IC card 100 is electrically contacted with a pad which is an external contact. At this time, as described above, a latching claw is formed at the rear end of the spring member support arm 38 of the slider 30, and the latching claw is configured to be locked to a step portion formed on the bottom wall 12. In this case, the forward movement of the slider 30 by the second spring member 52 is reliably prevented.

  On the other hand, in the eject member 40, the SD card or MMC card as the second IC card to be inserted comes into contact with the step formed in the corresponding guide groove, and the eject member 40 is the same as in the case of the memory stick. Is moved backward against the first spring member 50. When the SD card or MMC card pad comes into contact with the contact 70, the eject member 40 is locked with the other end of the cam lever 58 engaged with the heart cam 54.

  Finally, when inserting the XD card as the third IC card which is the smallest IC card, the XD card inserted from the card insertion slot 8 moves rearward as it is and is an external contact of the XD card. The pad contacts the contact portion 82 of the contact 80 of the third contact row arranged in the forefront.

  On the other hand, as in the case of the SD card or MMC card, the eject member 40 has the tip of the XD card as the third card inserted into contact with a step formed in the corresponding guide groove, and the eject member 40 It moves backward against the first spring member 50. When the pad of the XD card comes into contact with the contact 80, the eject member 40 is locked with the other end of the cam lever 58 engaged with the heart cam 54.

  As described above, IC cards of different sizes can be attached to the IC card connector 1. When removing the mounted IC card, the mounted IC card is usually pushed slightly backward to disengage the cam lever 58 from the heart cam 54. As a result, the eject member 40 returns to the original position by the biasing force (returning force) of the twenty-first spring member 50. As a result, the IC card whose tip is in contact with the eject member 40 is removed from the card insertion slot 8. Discharged. Further, the slider 30 also returns to the initial position while being in an inclined state as the initial posture by the urging force (returning force) of the second spring member 52.

  By the way, the operation according to the present invention in the case where the mounted IC card is forcibly removed in the state where the SD card or the MMC card is mounted as shown in FIG. 3 will be described.

  As shown in FIG. 3 and more specifically in FIG. 4, when the second IC card 100 such as an SD card is mounted, the second spring member 52 is moved backward by the slider 30. Compressed. Further, the slider 30 side of the second spring member 52 is inclined along the inclined surface 12 a of the bottom wall 12 of the base member 10 by the rotation of the slider 30. In other words, the second spring member 52 in the state of FIG. 4 is attached to the bottom wall 12 via the support protrusion 34 and the spring member support arm 38 so as to return to the original horizontal state as shown in FIG. The slider member 30, which is tilted substantially horizontally along, is biased forward and upward.

  In this state, if the second IC card 100 is forcibly pulled out from the IC card connector 1 by hand, it is released from the force pressing the slider 30 horizontally against the restoring force of the second spring member 52. Will be. Therefore, as shown in FIG. 5, the slider 30 that is biased upward and forward by the second spring member 52 is in an inclined state that is the initial posture, and the contact portion 72 of the contact 70 is placed in the slit 32. It returns to its original position while being housed. At this time, the eject member 40 remains locked because the eject mechanism is operating.

  As described above, in the present invention, even when the second IC card 100 is forcibly removed from the card housing space of the IC card connector 1, the slide member 30 does not depend on the position of the eject member 40. Then, it returns to the predetermined position in the inclined state which is the initial posture. Therefore, since the contact 70 located in the second contact row does not protrude into the card accommodation space, the tip of the IC card abuts against the contact 70, particularly the contact portion, no matter which IC card is inserted again. The contact 70 is not deformed or buckled.
