  As described above, the card connector disclosed in Patent Document 1 is not provided with the erroneous insertion prevention protrusion. Therefore, when the first card is inserted back and forth in the upper space, the rear end of the first card abuts on the card receiving portion of the slider constituting the eject mechanism and is completely mounted in the upper space. Absent. However, since the first card inserted backward and forward is allowed to advance until the slider reaches the end wall of the base member, the rear end of the first card corresponds to the front end of the corresponding first contact. There is a risk of deforming the first contact.

  Therefore, in order to prevent the deformation of the contact due to the erroneous insertion of the first card, the erroneous insertion preventing protruding piece disclosed in Patent Document 2 is adopted as the partition member of the card connector disclosed in Patent Document 1. Can be considered. However, since the protrusion for preventing erroneous insertion needs to be formed so as to be able to move in the recess where the electrode pad of the first card is provided, it must be smaller than the depth of the recess. Is limited. Therefore, when such an erroneous insertion preventing projection piece is simply employed, the erroneous insertion preventing projection piece itself is also pushed down by pushing down the partition member. Thereby, the tip end portion of the first contact is exposed in the upper space from the erroneous insertion preventing projection piece provided on the partition member. As a result, there is a possibility that the erroneous insertion preventing protruding piece moves and the rear end of the first card comes into contact with the front end portion of the first contact, causing the first contact to be deformed.

  The object of the present invention is that the contact tip is not exposed from the protective wall for preventing erroneous insertion, thereby preventing contact deformation even when the card is erroneously inserted and reducing the contact height. It is to provide a possible card connector.

  In order to achieve the above object, a card connector according to the present invention forms a card accommodation space having a card insertion slot by a base member including a front wall, left and right side walls, and a bottom wall and a cover member, and the card accommodation space. A card connector in which any one of a first card and a second card having a size different from that of the first card is selectively accommodated, and is disposed above the card accommodation space. A plurality of contacts including a plurality of first contacts for a first card and a plurality of second contacts for a second card disposed below the card accommodation space, and a plurality of first contacts 1 contact and a plurality of second contacts are vertically divided, and are formed so as to be able to move in the card accommodating space in response to the insertion and removal of the first and second cards. And an eject member provided to be movable in the front-rear direction along either one of the left and right side walls in the card connector, and the partition member accommodates the tip of each of the plurality of first contacts. The ejector member includes a main body portion that is slidable in the front-rear direction within the card connector, a first contact that is connected to the main body portion and abuts against the front end surface of the first card. A contact member and a second contact member connected to the main body portion and contacting the front end surface of the second card; the second contact member is disposed below the partition member; and the first card is When mounted, it has a flat first support surface that supports the partition member.

  The card connector of the present invention is also configured such that the first card is provided on the bottom wall of the base member, on the side of the side wall on which the ejection member moves in the front-rear direction, or on the other side of the left and right side walls opposite thereto. A support member having a second or third support surface for supporting the partition member may be formed when the is mounted.

  Furthermore, the card connector according to the present invention forms an engagement hole into which an engagement piece provided at the front end portion of the partition member is fitted below the front wall of the base member, and the height of the engagement hole. Is preferably set to be equal to the length of the second card plus the thickness of the engagement piece.

  In the card connector according to the present invention, it is preferable that a pressing protruding piece protruding upward is formed on the upper surface of the second contact member of the ejecting member.

  The present invention enables the partition member to be moved in the card housing space, and configures the card connector so that the occupied spaces of the first and second cards partially overlap in the card housing space of the card connector. It is possible to prevent two cards from being inserted at the same time and to reduce the height of the card connector. Further, by providing a protective wall on the partition member, it is possible to prevent damage such as deformation of the contact when the IC card is erroneously inserted. Further, by providing a configuration in which the first and second contacts are separated from each other vertically, when either the first or second card is mounted, the first or second card that does not contact the mounted first or second card By using the repulsive force of the second contact and pressing the partition member against the mounted card, the card can be securely held.

  In the present invention, by forming one or more support surfaces for supporting the partition member, the partition member can be reliably held parallel to the bottom wall, and the partition member is tilted or lowered too much. In other words, electrical contact between the mounted first card and the first contact is ensured, and a contact pressure failure is not caused.

  According to the present invention, by engaging the engagement piece with the engagement hole so as to be movable, the partition member can be reliably held in parallel even when the second card is mounted. Contact can be ensured.

  The present invention also provides a pressing protrusion on the second abutting member, so that the second card does not get over the second abutting member and prevents contact failure.

Specifically, the thickness (T ₃₇ ) of the second contact member 37 is obtained by subtracting the thickness T ₁₀ of the first card and the thickness t of the partition member 40 from the height T ₃₀ of the card accommodation space. It becomes equal to the thickness (T ₃₇ = T ₃₀ -T ₁₀ -t).

In the present embodiment, a pressing protrusion piece 38 having a rectangular horizontal cross section is further formed on the upper surface 37c of the second contact member 37 so as to protrude upward. In this embodiment, the pressing protrusion piece 38 is formed so as to extend over the entire front-rear direction of the upper surface 37 c of the second contact member 37. The pressing protrusion 38 is formed so as to be movable in the front-rear direction in a slit 47 of the partition member 40 described later. The pressing protrusion 38 is a member for preventing the second card 120 in contact with the second contact member 37 from moving forward over the second contact member 37. The length from the upper surface of the pressing protrusion 38 to the bottom surface of the second contact member 37 is set to be the same as or slightly smaller than the thickness T ₂₀ of the second card. Therefore, it is understood that the height T ₃₈ of the pressing protrusion piece is set to approximately T ₃₈ = T ₂₀ −T ₃₇ . The rear end surface of the pressing protrusion piece 38 is preferably formed flush with the vertical surface 37 a of the second contact member 37. The first and second contact members 36 and 37 can be formed integrally with the main body portion 33 of the eject mechanism 30. In addition, the bottom surface of the second contact member 37 and the bottom surface of the main body portion 33 in the card accommodation space are flush with each other so that they can slide in the front-rear direction along the top surface of the bottom wall 21 of the base member 20. Preferably it is formed.

  Next, the partition member 40 that distributes the IC cards to be attached (in the present embodiment, the first card 110 and the second card 120) will be described. As schematically shown in FIG. 2, the partition member 40 is disposed in the card storage space in front of the line connecting the partition walls 23b and 24b of the left and right side walls 23 and 24, and is large in the card storage space. Sort and guide different cards up and down. In the present embodiment, as shown in FIGS. 2 to 5, the partition member 40 divides the card accommodation space into an upper space and a lower space, and separates the plurality of first contacts 80 and the plurality of second contacts 90. Separated vertically. In the present embodiment, the partition member 40 further separates the first contact member 36 and the second contact member 37 of the eject member 32 in the vertical direction.

  In the present embodiment, as shown in FIG. 2, the partition member 40 is in a first position inclined forward and downward when the card 110 or 120 is not inserted. When the first card 110 is guided on the partition member 40 and installed in the upper space of the card accommodation space, the partition member 40 has first to third support surfaces 37c as shown in FIG. , 21a, 21b until it comes into contact. The partition member 40 finally moves to a second position that is held by the first to third support surfaces 37c, 21a, and 21b and that is parallel to the bottom wall 21 as a whole. When the second card 120 is guided under the partition member 40, as shown in FIG. 12, until the engagement piece 44 of the partition member 40 comes into contact with the upper end of the engagement hole 22b of the front wall 22. Ascend and move to a third position which is parallel to the bottom wall 21 as a whole.

  In this embodiment, as shown in FIGS. 6 and 7, the partition member 40 is a plate body having a substantially flat horizontal cross section and is formed of a hard plastic. The partition member 40 includes a plurality of protective walls 41 corresponding to each of the plurality of first contacts 80, a pair of guide pieces 42, 42, and a pair of drive pieces 43, 43 (in FIG. 7, only the right drive piece 43 is shown. And a plurality of engaging pieces 44.

  Each of the plurality of protective walls 41 is provided at a predetermined position on the upper surface of the partition member 40 corresponding to the arrangement position and size of each of the plurality of first contacts 80. More specifically, each of the plurality of protective walls 41 has a partition member according to the arrangement positions of the plurality of pads of the first card 110 and the shapes and sizes of the plurality of groove portions 113 provided with the plurality of pads. It is formed at a predetermined position on the upper surface of 40. The protective wall 41 is formed with a contact receiving recess 41 a so as to surround the tip 81 a of the corresponding first contact 80. In the present embodiment, the housing recess 41a is formed as a through-hole penetrating the protective wall 41 in the front-rear direction as shown in FIGS. When the first card 110 is mounted, the protective wall 41 moves in the groove 113 in which the pad 114 of the first card 110 is formed, and is accommodated in the back of the groove 113. Therefore, the dimension and position of the protective wall 41 can be appropriately set corresponding to the width (length in the left-right direction), depth (length in the up-down direction), and depth (length in the front-rear direction) of the groove 113. . The protective wall 41 does not have to correspond one-to-one with each of the plurality of first contacts 80. For example, as shown in FIG. 14, when two pads are arranged in parallel in one groove 113 of the first card 110, one protective wall 41 may be provided correspondingly. However, as shown in FIGS. 3, 6, and 8, two accommodating recesses 41 a provided in the one protective wall 41 correspond to the two first contacts 80 and are parallel to the protective wall 41. It is preferable to be formed. Alternatively, if the two first contacts are fixed to the front wall 22 of the base member 20 so as not to come into contact with each other, the housing recess 41a may be formed as a single unit.

  In the present embodiment, the protective wall 41 and the housing recess 41a formed in the protective wall 41 have a rectangular shape in the vertical cross section in the vertical and horizontal directions, but are not limited thereto. In short, it is only necessary that the tip 81a of the first contact 80 is surrounded by the receiving recess 41a in the upper, lower, left and right directions and is received in the receiving recess 41a. The bottom surface 41b of the housing recess 41a is preferably formed one step lower than the top surface of the partition member 40. As a result, the amount of vertical displacement of the first contact 80 can be increased. Moreover, the rear end surface of the protective wall 41 may be formed as an inclined surface that descends rearward (see FIG. 8).

  In the present embodiment, a slit 47 that opens toward the front of the partition member 40 is formed in front of the partition member 40 and in front of the protective wall 41. A connecting member 45 that crosses the front end portion of the partition member 40 is provided on the lower surface of the front end portion of the partition member 40 to reinforce the front end portion of the partition member 40. The height (length in the vertical direction) of the connecting member 45 is preferably set to the same height as the first to third support surfaces 37c, 21a, 21b. On the front surface of the connecting member 45, a plurality of engagement pieces 44 that engage with the plurality of engagement holes 22 b formed between the bottom wall 21 and the front wall 22 of the base member 20 described above face forward. It is formed to protrude. The size of the engaging piece 44 is set so that it can be engaged in the engaging hole 22b so as to move up and down.

In this embodiment, as clearly shown in FIGS. 6 and 7, a pair of guide pieces 42 and 42 are provided on both sides of the rear end portion of the partition member 40. The pair of guide pieces 42 are formed on the lower surface of the partition member 40 and project upward from the side surfaces of the pair of leg portions 46, 46 provided on both sides of the rear end portion in a symmetrical L-shape. The More specifically, the pair of guide pieces 42, 42 extend from the side surfaces of the pair of leg portions 46, 46 toward the outside on both sides of the partition member 40, and then perpendicular to the flat upper surface of the partition member 40. Thus, they are formed parallel to each other so as to extend a predetermined length upward. The height (length in the vertical direction) of the pair of guide pieces 42 and 42 is the same, and the height of the second card (T ₂₀ ) from the height of the card receiving space (T ₃₀ ). Is set equal to the length minus. In the present embodiment, the pair of guide pieces 42, 42 are vertical guides formed on the partition walls 23 b, 24 b provided on the left and right side walls 23, 24 of the base member 20 when the partition member 40 is incorporated in the card connector 1. It fits in the grooves 23d and 24d so as to be movable up and down. At this time, the pair of guide pieces 42 and 42 is also provided with a push-up spring 49 such as a coil spring between the pair of guide pieces 42 and 42 and the bottom wall 21 in the vertical guide grooves 23d and 24d. The Therefore, each of the pair of guide pieces 42 and 42 is pushed upward by the urging force of the push-up springs 49 and 49. Accordingly, the pair of guide pieces 42 and 42 are pressed against the lower surface of the top plate 11 of the cover member 10 in the vertical guide grooves 23d and 24d. The height (length in the vertical direction) of the pair of leg portions 46 and 46 is preferably set to be the same as the height of the connecting member 45.

  In the present embodiment, as shown in FIGS. 2 and 7, a pair of drive pieces 43 and 43 are provided on both sides of the rear end portion of the partition member 40. The pair of drive pieces 43 protrude from the pair of leg portions 46, 46 of the partition member 40 symmetrically on both sides of the partition member 40, in parallel to the flat upper surface of the partition member 40, and toward the rear. And they are formed parallel to each other. The pair of drive pieces 43 are formed to extend rearward by a predetermined length from the rear end surfaces of the pair of leg portions 46 and 46 so that the actuator 70 described later can be engaged with the actuator 70 when the actuator 70 rotates. Has been. With the rotation of the actuator 70, the pair of drive pieces 43 and 43 are engaged with a pair of engagement springs 49 and 49 by further rotation of the actuator 70 after engaging with a pair of engagement recesses (not shown) formed in the actuator 70. It is pushed downward against the urging force. Thereby, when the rear end portion of the partition member 40 is lowered and the first card 110 reaches the rear end of the partition member 40, the first card 110 can be guided onto the partition plate 41. Become. After that, the first card 110 is guided in the upper space of the card accommodation space by the pair of guide pieces 42 and 42, and in this embodiment, the partition member 40 that has been inclined is shown in FIG. As a result, the partition member 40 moves to a second position parallel to the bottom wall 21.

  When the partition member 40 is assembled as the card connector 1, as described above, the partition member 40 traverses the card accommodation space and is disposed at a first position inclined in a front-down manner in which the front of the partition member 40 is positioned downward. The That is, the front end portion of the partition member 40 is lowered by its own weight, and is supported by the bottom wall 21 by the lower surface of the connecting member 45 provided at the front end portion contacting the upper surface of the bottom wall 21. Further, the rear end portion of the partition member 40 is moved to a predetermined position (the upper surfaces of the pair of guide pieces 42 and 42 of the partition member 40 are brought into contact with the lower surface of the top plate 11 of the cover member 10 by the urging force of the pair of push-up springs 49 and 49. It is lifted up to the abutting position) and supported by the bottom wall 21.

  Subsequently, the insertion of a card other than the first card 110 is prevented, and when the first card 110 is inserted, the partition member 40 is lowered to guide the first card 110 into the upper space of the card accommodation space. The actuator 70 will be briefly described.

  The actuator 70 includes a shutter portion 71, a pair of protruding pins 72, 72, a pair of leg portions 75 (only the right leg portion 75 is shown in FIGS. 2 to 4), and a pair of rotating shafts (not shown). Contains. The actuator 70 is disposed across the card storage space and is rotatably arranged in the card storage space. In addition, the actuator 70 forms a passage opening having a substantially rectangular cross section through which the second card 120 can pass by the shutter portion 71 and the pair of leg portions 75.

  As shown in FIGS. 2 to 4, when the IC card is not mounted, the shutter unit 71 is orthogonal to the card insertion direction, crosses the card storage space to the left and right, and closes the upper space of the card storage space. Are arranged as follows. A pair of projecting pins 72 and 72 projecting into the left and right rear receiving grooves 23a and 24a are formed on the left and right sides of the shutter portion 71, respectively. As shown in FIGS. 3 and 4, the pair of protruding pins 72, 72 has openings 64, 64 of the corresponding pair of lock fittings 60, 60, respectively, as described above, when the IC card is not attached. Is engaged.

A pair of leg portions 75 and 75 are formed on the left and right sides of the shutter portion 71 and inside the pair of projecting pins 72 and 72, respectively. The vertical cross section is formed by the shutter portion 71 and the pair of leg portions 75 and 75. A rectangular passage opening is formed (see FIGS. 3 and 4). The shape of the vertical cross section of the passage opening is set to be substantially the same as or slightly larger than the vertical cross section of the second card 120. In other words, the interval between the pair of leg portions 75 and 75 is the same as the width W ₂₀ of the second card 120, and thereby is substantially the same as the interval between the pair of lower guide paths 27 and 27. Engagement recesses (not shown) are formed on the front surfaces of the pair of legs 75, 75, respectively. The pair of engaging recesses engages with the pair of drive pieces 43, 43 of the partition member 40 when the actuator 70 rotates, and pushes down the pair of drive pieces 43, 43. As a result, the rear end portion of the partition member 40 Press down.

  A pair of rotating shafts (not shown) project from the lower ends of the pair of leg portions 75 and 75 toward the left and right outer sides from the lower ends. The pair of rotating shafts are respectively disposed in the rear receiving grooves 23a and 24a of the left and right side walls 23 and 24, traverse the bottoms of the rear receiving grooves 23a and 24a, and are rotatably supported by the left and right side walls 23 and 24. Is done. A torsion coil spring (not shown) is wound around one or both of the pair of rotating shafts. The torsion coil spring urges the shutter portion 71 of the actuator 70 to be in an upright position, that is, a first position that closes the card accommodating space, as shown in FIGS.

  As shown in FIGS. 2 to 4, the actuator 70 is normally in a first position where the shutter portion 71 closes the upper space of the card accommodation space. As will be described later, when the first card 110 is inserted, the actuator 70 is disengaged from the lock fitting 60 and becomes rotatable about a pair of rotation shafts (not shown). When the first card 110 is further inserted, the shutter portion 71 comes into contact with the first card 110, the actuator 70 is pushed forward while rotating, and the shutter portion 71 moves over the space above the card accommodation space. It rotates to the 2nd position which opens (refer FIG. 9, 10). Further, when the second card 120 is inserted, the actuator 70 passes through the passage opening formed in the actuator 70 without rotating (see FIGS. 11 and 12).

  The card connector 1 according to the present invention has the above configuration. Hereinafter, a specific operation for selectively mounting the IC card to the card connector 1 according to the present invention will be described mainly with reference to FIGS.

  First, the operation of mounting the first card 110 on the card connector 1 according to the present invention will be described.

  As shown in FIGS. 2 and 3, when the first card 110 is not mounted, the lock fittings 60, 60, the actuator 70 and the partition member 40 forming a pair of the card connector 1 are all in the first position. is there. Specifically, the contact portions 62 and 62 forming a pair of each of the pair of lock fittings 60 and 60 are in the first closed position, and the actuator 70 has a first position in which the shutter portion 71 closes the upper space of the card accommodation space. 1 position. At this time, the openings 64, 64 forming a pair of the pair of lock fittings 60, 60 and the corresponding pair of projecting pins 72, 72 of the actuator 70 are engaged with each other. In the partition member 40, a part of the connecting member 45 provided at the front end part contacts the bottom wall 11 of the base member 20, and a pair of guide pieces 42, 42 provided on both sides of the rear end part is provided with a push-up spring 49. Therefore, the cover member 10 is in contact with the top plate 11 and is in the inclined first position. Therefore, the rear end portion of the partition member 40 is pushed up to a height substantially equal to the thickness of the second card 120.

  The first card 110 is now inserted from the card insertion slot 5 in a normal state with the surface on which the plurality of bads 114 are formed facing down. That is, the wide upper body 111 of the first card 110 is inserted from the card insertion slot 5 along the upper guide paths 25, 25 and the narrow lower body 112 along the middle guide paths 26, 26.

  When the first card 110 is inserted forward, a pair of wide upper bodies 111 project into the card accommodation space through the openings 25a, 25a formed in the upper guide paths 25, 25. The lock fittings 60, 60 come into contact with the contact portions 62, 62 forming a pair. By this contact, the paired contact portions 62 and 62 are simultaneously retracted from the card accommodation space into the rear accommodation grooves 23a and 24a, respectively. That is, the contact portions 62 and 62 that make a pair are moved to the second position. Thereby, the elastic deformation pieces 61 and 61 forming a pair of the pair of lock fittings 60 and 60 are opened (moved to the second position), and the opening 64 forming each pair of the elastic deformation pieces 61 and 61 forming the pair, 64 and the corresponding pair of projecting pins 72 and 72 of the actuator 70 are simultaneously disengaged, so that the actuator 70 becomes rotatable.

  When the first card 110 is further inserted and advanced from this state, the tip of the first card 110 comes into contact with the shutter portion 71 of the actuator 70. At this time, as described above, the actuator 70 is in a rotatable state. Accordingly, as the first card 110 advances, the actuator 60 rotates so as to be pushed forward against the biasing force of the torsion coil spring (see FIG. 9). During the rotation of the actuator 70, a pair of engaging recesses (not shown) provided in the pair of legs 75, 75 of the actuator 70 engage with the pair of left and right drive pieces 43, 43 of the partition member 40. .

  When the first card 110 is further inserted, the actuator 70 rotates to the second position where it is completely collapsed, and the upper space of the card accommodation space is opened so that the first card 110 can pass through. As a result, the first card 110 moves forward over the shutter portion 71 of the actuator 70.

  At this time, the rotation of the actuator 70 to the second position sufficiently depresses the pair of drive pieces 43 and 43 and depresses the rear end portion of the partition member 40. Therefore, the front end of the first card 110 is in a state where it can ride on the rear end portion of the partition member 40.

  When the first card 110 is further inserted from this state, the partition member 40 is positioned parallel to the upper surface of the bottom wall 21 of the base member 10 as the first card 110 advances, that is, the second position. Move up. Specifically, the partition member 40 includes an upper surface 37c of the second contact member 37 of the eject member 32 formed as the first to third support surfaces, an upper surface of the first support member 21a, and a second support member. It moves until it contacts the upper surface of 21c. Thereby, the partition member 40 is held on the first to third support surfaces so as to be parallel to the upper surface of the bottom wall 21 of the base member 10 and therefore to be parallel to the top plate 11 of the cover member 10. Is done. At this time, the plurality of first contacts 80 in which the front end portions 81a are housed in the housing recesses 41a formed in the protective wall 41 of the partition member 40 are respectively moved along with the movement (downward movement) of the partition member 40. The contact portion 81 formed so as to protrude upward is exposed upward from the corresponding protective wall 41. As a result, the plurality of first contacts 80 can contact the corresponding plurality of pads 114 of the first card 110, respectively. In this case, the tip 81a of the first contact 80 still exists in the housing recess 41a and restricts the protruding amount of each contact portion 81.

  When the first card 110 further advances over the partition member 40 in the second position, the card front end surface 117 and the inclined surface 116 of the first card 110 become the first contact member 36 of the eject member 32. It abuts on the formed vertical surface 36a and inclined surface 36b, respectively. The first card 110 is further advanced toward the front against the urging force of the compression coil spring 39 of the eject mechanism 30 and is pushed in until the front end surface of the eject member 32 reaches the front wall 22 of the base member 20. . At this time, the plurality of protective walls 41 formed in the partition member 40 are accommodated in the corresponding plurality of groove portions 113 in which the plurality of pads 114 of the first card 110 are formed, respectively. The card 110 is not prevented from moving forward.

  In the state where the first card 110 is pushed in as much as possible, if the pushing force is removed from the first card 110, the first card 110 is pushed back slightly by the action of the push-push type eject mechanism 30. The first card 110 is held in the card accommodation space (upper space) of the card connector 1 in a state where the first card 110 is pushed back slightly. At this time, it goes without saying that the plurality of pads 114 of the first card 110 are in contact with the corresponding first contacts 80, respectively.

  As shown in FIG. 10, the first card 110 is placed in the card accommodation space against the urging force of the pair of push-up springs 49 arranged between the partition wall 40 and the bottom wall 21. A partition member 40 is pushed down to the second position. In other words, the partition member 40 is in contact with the surface of the lower main body 112 of the first card 110 and is in a second position parallel to the bottom wall 21, and presses the first card 110 against the top plate 11. Therefore, the plurality of pads 114 of the first card 110 can make electrical contact with the corresponding plurality of first contacts 80 at an appropriate contact pressure. Note that when the first card 110 is mounted in the card housing space of the card connector 1, the lower surface side of the partition member 40 may contact the plurality of second contacts 90 for the second card 120. In this way, the back side of the partition member 40 comes into contact with the plurality of second contacts 90, so that the first card 110 is securely held between the partition member 40 and the top plate 11. Repulsive force can be used.

  When the first card 110 has the rear end surface as the front end, that is, when the first card 11 is erroneously inserted backward and forward, the rear end surface is the inclined surface 36b of the first contact member 36 or the protective wall 41. The first card 110 is prevented from moving forward to a predetermined position. Further, since the front end portion 81a of the first contact 80 is in the receiving recess 41a of the protective wall 41, even if the first card 110 is pushed over the protective wall 41, the rear end surface thereof is the first contact 80. It does not contact and damage the tip 81a. Similarly, even if an unexpected IC card having the same width as the upper main body 111 of the first card 110 is inserted into the upper guide path 25, the mounting of the unexpected IC card is prevented. That is, the unexpected IC card is not formed with the corresponding notched inclined surface 116 and the plurality of groove portions 113, so that it contacts the inclined surface 36 b of the first abutting member 36 and the protective wall 41 of the partition member 40. The advance of the first card 110 to a predetermined position is prevented. Further, the unexpected contact of the IC card over the protective wall 41 does not damage the first contact 80.

  When removing the first card 110 from the card connector 1, the first card 110 at a position slightly retracted from the state of FIG. 10 is pushed forward. Subsequently, the first card 110 is pushed in with the front end face 117 of the first card 110 abutting against the front wall 22 of the base member 20 and the first card 110 is pushed to the maximum extent. Remove the power. Thereby, the first card 110 is ejected from the card connector 1 by the action of the eject mechanism 30. Further, the lock fittings 60, 60, the actuator 70, and the partition member 40 forming a pair of the card connector 1 are returned to the first position where they were originally located.

  Next, the operation of mounting the second card 120 on the card connector 1 according to the present invention will be described.

The second card 120 is now inserted from the card insertion slot 5 along the lower guide paths 27 and 27 in a normal state with the surface on which the pad 123 is formed facing down. Since the insertion of the second card 120 is guided along the lower guide path 2727, it does not contact the lock fittings 60, 60, and therefore the actuator 70 is still in the first position. However, since the second card 120 can pass through the passage opening provided in the actuator 70, the second card 120 can move forward in the card accommodation space as it is. At this time, the partition member 40 has a rear end portion at a first position slightly higher than the thickness T ₂₀ of the second card 120. Therefore, the second card 120 can be inserted into the lower space below the partition member 40 that divides the card accommodation space into upper and lower portions, and can advance between the partition member 40 and the bottom wall 21 of the base member 20.

  As the second card 120 further advances between the partition member 40 and the bottom wall 21 of the base member 20, the front end portion of the partition member 40 in the first position in contact with the bottom wall 21 of the base member 20. Rises. The partition member 40 is pushed up until the plurality of engagement pieces 44 of the connecting member 45 provided at the front end abut against the upper surfaces of the corresponding plurality of engagement holes 22b provided in the front wall 22 of the base member 20. . The partition member 40 is finally in a third position parallel to the upper surface of the bottom wall 21 as a whole when the second card 120 is completely attached to the card connector 1 as shown in FIG. At this time, the partition member 40 pushes up the plurality of first contacts 80 in the plurality of receiving recesses 41 a formed in the plurality of protection walls 41.

  By the way, the second card 120 moving forward between the partition member 40 and the bottom wall 21 abuts on the vertical surface 37 a of the second abutting member 37 of the eject member 32 and the pressing protrusion piece 38. Similar to the first card 110, the second card 120 further advances toward the front against the urging force of the compression coil spring 39 of the ejection mechanism 30, and the front end surface of the ejection member 32 is the base member 20. Until the front wall 22 is reached. At this time, since the protruding portion 21c formed on the bottom wall 21 of the base member 20 is accommodated in the first groove portion 125 of the second card 120, the second card 120 is prevented from moving forward. There is nothing.

  In this state, when the pushing force from the second card 120 is removed, the second card 120 is pushed back slightly slightly by the action of the push-push type eject mechanism 30 (below the card receiving space (below the card housing 1). Held in space). At this time, the plurality of pads 123 of the second card 120 can contact the corresponding plurality of second contacts 90, respectively.

  As shown in FIG. 12, the second card 120 moves the partition member 40 to the third position against the repulsive force of the plurality of first contacts 80 pushed up by the plurality of receiving recesses 41 a of the partition member 40. It is pushed up to the position. In other words, the partition member 40 contacts the surface of the second card 120 and is in a third position parallel to the bottom wall 11, and uses the repulsive force of the plurality of first contacts 80 to make the second card 120. Is pressed against the bottom wall 21. Therefore, the plurality of pads 123 of the second card 120 can be in electrical contact with the corresponding plurality of second contacts 90 with appropriate contact pressures.

  Even if the second card 120 is mistakenly inserted along the upper guide path 16, the width of the second card 120 is small, so that the contact portions 62, 62 forming a pair of the pair of lock fittings 60, 60 are provided. Cannot be moved to the second position at the same time. Therefore, the actuator 70 is not allowed to rotate, and the second card 120 can be inserted in front of the shutter member 71 of the actuator 70. Be blocked. Thereby, the second card 120, the card connector 1, and further the electronic device connected via the card connector 1 are not damaged. Further, for example, when the second card 120 is erroneously inserted into the lower guide path 27 in the reverse direction, the rear end surface of the second card 120 is formed on the protruding portion 21 c provided on the bottom wall 21 of the base member 20. Since the contact, the advance of the second card 120 to a predetermined position is prevented. Alternatively, even when an unexpected card having the same width as that of the second card 120 is inserted into the lower guide path 27, the front end surface of the unexpected card abuts against the protrusion 21c, and an unexpected IC Advancement of the card to a predetermined position is prevented.

  Since the operation when removing the second card 120 from the card connector 1 is substantially the same as the operation when removing the first card 110, description thereof is omitted.
