Description

  The present invention provides a card ejection prevention mechanism for preventing an IC card from ejecting from a card connector when an IC card accommodated in the card connector is ejected by a card ejection mechanism (hereinafter referred to as “eject mechanism”). The present invention relates to a card connector provided.

  In an electronic device such as a mobile phone or a digital camera, the function is expanded by attaching various IC cards with a built-in CPU or memory IC. A card connector used for detachably attaching such an IC card to an electronic device is provided with an eject mechanism for facilitating attachment / detachment of the IC card to / from the card connector. In recent years, as IC cards have become smaller and thinner, there has been a risk that the IC card will jump out of the card connector when ejected from the card connector by the eject mechanism.

  Therefore, the card connector is further devised to include a card pop-out prevention mechanism as disclosed in Patent Document 1 in order to prevent such an IC card from popping out from the card connector. In the card pop-out prevention mechanism disclosed in Patent Document 1, a claw portion is formed on an ejection member that constitutes a push-push type ejection mechanism. In addition, a leaf spring that urges the claw portion of the eject member toward the card housing space side (inside the card connector) is cut and raised from the cover member constituting the card connector. Further, the eject member is slidably and rotatably attached to a base member constituting the card connector.

  The card ejection mechanism configured as described above operates as follows. When the IC card is attached to the card connector, the claw portion of the eject member is engaged with the concave portion provided in the side portion of the IC card. This prevents inadvertent disconnection from the card connector when the IC card is mounted. When the IC card is ejected, the card ejection mechanism is driven by pushing in the IC card, thereby executing the card ejection operation. At the end of the IC card ejection operation, the IC card is temporarily stopped in a state where a part of the IC card remains in the card connector because the claw portion of the eject member is engaged with the concave portion of the IC card. In other words, the IC card never pops out from the card connector. From this state, the IC card is pulled out from the card connector by grasping the portion pushed out from the card connector of the IC card. At this time, the eject member is in a rotatable state, and the engagement between the concave portion of the IC card and the claw portion of the eject member is released. At this time, the eject member is urged toward the card accommodating space by the leaf spring, so that there is a slight resistance to the disengagement between the concave portion and the claw portion, so that the user is conscious of pulling out the IC card. In this way, the IC card can be reliably removed from the card connector.

JP 2005-301983 A

  By the way, in the conventional card connector, the ejector and the member are always urged toward the card accommodating space side by a plate spring cut and raised from the cover member constituting the card connector. Therefore, even when the IC card is mounted on the card connector, the pressing force (biasing force) on the eject member of the leaf spring requires a slight force to engage the concave portion of the IC card and the claw portion of the eject member. To do. Further, when the IC card is pushed together with the eject member, the pressing force of the leaf spring acts as a braking force against the sliding of the eject member, and affects the IC card mounting operation.

  Further, in terms of design, it may be configured such that the pressing force of the leaf spring becomes zero when the eject member slides. However, precision is required at the time of manufacturing the card connector, which takes time and cost. In order to avoid this, when assembled, the leaf spring is cut and raised from the cover member so as to allow the leaf spring to press the eject member toward the card receiving space. In this case, when the cover member is incorporated into the base member, it is necessary to devise so that the leaf spring formed on the cover member does not hit the eject member, and in this case also, manufacturing time and cost are required.

  In view of such problems, the object of the present invention is to provide a card pop-out prevention mechanism that improves the card pop-out prevention function more than the conventional one and is easy to manufacture despite its simple structure. The object is to provide a card connector.

  In order to achieve the above object, a card connector of the present invention is a base member that forms a cover member and a card housing space in which an IC card is mounted together with the cover member, and is a small protrusion protruding upward from the bottom wall thereof. And a card ejection mechanism for removing a mounted IC card, and an eject member that is movable in the front-rear direction on the base member, and is a notch recess provided in the mounted IC card. An ejector member that has a claw portion that can be engaged with each other and an elongated cutout groove that accommodates the small protrusion at the end of the card discharge operation, and is formed to be rotatable at the end of the card discharge operation. Each notch groove is formed with an inclined surface that abuts when the eject member rotates.

  Moreover, it is preferable that the inclined surface formed in each of the small protrusion and the notch groove has an angle within a range of 30 degrees to 60 degrees with respect to a horizontal plane.

  According to the present invention, when the ejection operation is completed, the small protrusion of the base member is accommodated in the notch groove of the ejection member, so that the ejection member is rotated to disengage the nail portion of the ejection member from the notch recess of the IC card. Give resistance. Thus, the inertia provided by the IC card ejecting operation by the eject mechanism prevents the claw portion of the eject member from being easily detached from the notch recess of the IC card. In other words, the prevention of jumping out of the card connector of the IC card is made more reliable than the conventional one.

  Further, since the structure is simple and the number of manufacturing processes is small, the assembly is easy, the manufacturing time is shortened, and the manufacturing cost is reduced.

  Hereinafter, preferred embodiments of a card connector according to the present invention will be described with reference to the drawings.

That is, the base member 20 is overlapped with the cover member 30 to form a card accommodation space for accommodating the IC card 100. The rear portion of the right side wall 22 of the base member 20 is formed wide so as to protrude toward the card accommodation space via the step portion 22a.

  A plurality of groove portions 27 are formed in the bottom wall 25 of the base member 20 in parallel with each other in the front-rear direction in order to fix each of the plurality of contacts 40. A first guide hole 41 is formed in front of the right side wall 22 of the bottom wall 25 of the base member 20 in parallel with the right side wall 22. As clearly shown in FIG. 5, the first guide hole 41 accommodates a first pin 61 of an eject member 51 described later, and guides the movement of the eject member in the front-rear direction. The first guide hole 41 is formed in an ellipse having a width slightly larger than the outer diameter of the first pin 61.

  A small protrusion 26 is formed on the bottom wall 25 of the base member 20 so as to enter and exit a cutout groove 58 of an eject member 51 described later (see FIG. 7). The small protrusions 26 constitute a card pop-out preventing mechanism 70 described later.

  The cover member 30 is made of metal and maintains the rigidity of the card connector 10. The cover member 30 includes a top plate 31, a left side wall 32, a right side wall 33, and a front wall 34, and the lower and rear sides are open. When the cover member 30 is overlapped with the base member 20, the left side wall 32, right side wall 33, and front wall 34 of the sheet metal cover 30 are the left side wall 21, right side wall 22, front side of the base member 20. It is designed to cover the wall 23. Reference numeral 35 denotes a window or opening, reference numeral 36 denotes a cam lever press for holding the cam lever 54 of the ejection mechanism 50, and reference numerals 37 and 38 denote leaf springs for pressing and supporting the inserted IC card 100.

  The plurality of contacts 48 are fixed to the base member 20 in parallel with each other by press-fitting the fixing portions of the contacts 48 into the plurality of grooves 27 provided in the base member 20 as in the conventional art.

  The eject mechanism 50 is a mechanism for controlling holding or releasing of the IC card 100, and the eject mechanism in the present embodiment employs a conventionally well-known push-push mechanism. The ejection mechanism 50 includes an ejection member 51, a heart cam 52, a guide groove 53, a cam lever 54, and a coil spring 55.

  The eject member 51 slides along the right side wall 22 of the base member 20 between the front wall 23 and the step 22a of the right side wall 23 in the front-rear direction of the card connector 10 (card insertion direction and card discharge direction). It is provided as possible. The eject member 51 includes a card abutting portion 56 that abuts on the leading end portion 101 of the IC card 100 to be inserted, an inclined portion 59 corresponding to the inclined shoulder portion 102 of the IC card 100, and an approximate shape formed on the IC card 100. It includes a claw portion 57 that engages with the cutout recess 103 having a shape. The card abutting portion 56 is formed to protrude toward the card accommodation space at the distal end portion of the eject member 51 and abuts against the distal end portion of the card 100 when the IC card is inserted as described above. Helps move the ejector forward. The claw portion 57 is formed so as to protrude toward the card accommodation space at the rear end portion of the eject member 51, and constitutes a card pop-out prevention mechanism described later.

  On the upper surface of the eject member 51, a heart cam 52 and a guide groove 53 formed so as to surround the heart cam 52 are formed. A leg portion formed at the front end of the cam lever 54 is fitted into the guide groove 53 and moves along the guide groove 53.

  A dome-shaped groove (not shown) in which the coil spring 55 can be accommodated is formed in front of the lower surface of the eject member 51. The dome-shaped groove is open at the front and lower sides, and the rear and upper sides are closed by walls. One end of the coil spring 55 is supported by the front wall 23 of the base member 20, and the other end is fixed to the rear wall of the dome-shaped groove of the eject member 51. A notch groove 58 that is open toward the rear and toward the back is provided at the rear of the lower surface of the eject member 51. The notch groove 58 constitutes a card pop-out prevention mechanism 70 described later.

  Further, a first pin 61 is formed on the lower surface side in the vicinity of the card contact surface 56 of the eject member 51 (see FIG. 5) and is accommodated in the first guide hole 41 of the base member 20. Further, a second pin 63 is formed on the lower surface of the eject member 51 and in front of the notch groove 58 (see FIG. 5), and is accommodated in the second guide hole 43 of the base member 20. With these configurations, the eject member 51 can smoothly move in the front-rear direction. Further, the eject member 51 is designed to be rotatable about the first pin 61 when the coil spring 55 is fully extended, that is, at the end of the eject operation (FIG. 4A and FIG. 4). 5 (a)).

  The cam lever 54 has a substantially inverted U shape having legs at the front and rear ends, the leg formed at the front end is movably fitted in the guide groove 53, and the leg formed at the rear end is The base member 20 is rotatably supported by the right side wall 22 behind the step 22a of the right side wall 22. When assembled, the cam lever 54 is prevented from falling off by a cam lever press 36 formed on the top plate 31 of the cover member 30.

  The coil spring 55 always urges the eject member 51 toward the card insertion slot 24. Thereby, the eject member 51 maintains the state of being pressed against the step portion 22a of the berth member 20 when the IC card is not attached.

  Next, the structure of the card pop-out prevention mechanism 70 according to the present invention will be described. The card pop-out prevention mechanism 70 includes an ejection member 51 that constitutes the ejection mechanism 50. That is, the card pop-out prevention mechanism 70 includes an eject member 51 that is formed to be rotatable, a claw portion 57 that is provided at the rear portion of the eject member 51, and a cutout that is also provided at the rear of the lower surface of the eject member 51. A groove 58 is included. The card pop-out prevention mechanism 70 further includes a small protrusion 26 provided on the base member 20 corresponding to the cutout groove 58 of the eject member.

  The card pop-out prevention mechanism 70 engages with the claw portion 57 of the eject member 51 and the notch recess 103 of the IC card 100, so that the IC card 100 is removed from the card connector 10 and the IC card 100 is ejected. Prevent cards from popping out. In addition, when the ejection operation is completed, the small protrusion 26 of the base member 20 exists in the notch groove 58 of the ejection member 51, so that the ejection member 51 can be detached from the notch recess 103 of the IC card 100. Resistance is given to the operation of rotating 51. This prevents the claw portion 57 of the eject member 51 from being easily detached from the notch recess 103 of the IC card 100 due to the inertia given by the IC card ejecting operation by the eject mechanism 50. That is, it is possible to further prevent the IC card 100 from protruding from the card connector 10.

  As described above, the claw portion 57 of the eject member 51 is formed to protrude toward the card accommodation space at the rear end portion of the eject member 51. The claw portion 57 of the eject member 51 is engaged with or detached from the notch recess 103 of the IC card 100. The claw portion 57 of the eject member 51 has an inclined surface in the front-rear direction in order to be able to engage with or disengage from the notch recess 103 of the IC card 100, that is, roughly seen from above. A triangular shape is preferred.

  As shown in detail in FIG. 7, the small protrusions 26 provided on the base member 20 have a generally elongated oval shape when viewed from above, and protrude upward from the bottom wall 25. Inclined surfaces 26a and 26b are formed at the upper ends of the opposing side walls 26A and 26B of the small protrusion 26. That is, the upper tips of the two side surfaces 26A and 26B facing each other of the small protrusions are formed so as to gradually narrow toward the upper side.

  As shown in detail in FIG. 7, the cutout groove 58 provided in the eject member 51 corresponding to the small protrusion 26 is provided at the rear of the lower surface of the eject member 51 and is opened rearward and downward. It is a long and narrow groove and has opposite side surfaces 58A and 58B. The side surfaces 58 </ b> A and 58 </ b> B are formed with inclined surfaces 58 a and 58 b that widen toward the lower surface of the eject member 51.

  The width of the notch groove 58, that is, the interval between the opposing side surfaces 58A, 58B is slightly larger than the width of the small protrusion 26, that is, the interval between the opposing side surfaces 26A, 26B. Further, the height of the inclined surfaces 58a, 58b of the side surfaces 58A, 58B facing each other of the notch groove 58 from the lower surface of the eject member 51 is the bottom wall of the base member 2 of the side surfaces 26A, 26B facing each other of the small protrusion 26. 25 may be set equal to or slightly lower than the height from the top surface. In this case, when the IC card 100 is pulled out from the card connector 10, the IC card 100 is slightly inclined with respect to the thickness direction by the leaf springs 37 and 38 of the cover member 30. Therefore, an upward force is generated on the eject member 51, whereby the inclined surfaces 58 a and 58 b of the notch groove 58 can ride on the inclined surfaces 26 a and 26 b of the corresponding small protrusions 26. Further, the inclined surfaces 58a and 58b of the notch groove 58 and the inclined surfaces 26a and 26a of the small protrusions 26 formed on the base member 20 have substantially the same angle with respect to the horizontal plane, and the angle is 30 °. It is preferably between ˜60 °. If the angle is 30 ° or less, the interference between the inclined surfaces (58a and 26a) is weakened, and the eject member 51 can easily rotate and the IC card 100 may be ejected. Further, when the angle is 60 ° or more, the interference between the inclined surfaces (58a and 26a) becomes strong, and the ejector member 51 or the base member 20 may be damaged when the IC card 100 is pulled out.

  Note that the small protrusions 26 and the cutout grooves 58 are not limited to the structure described above, and for example, the opposing side surfaces may not be formed only with the inclined surfaces. The small protrusions 26 are elongated and oval, but may be cylindrical or conical.

  As described above, the component parts constituting the card pop-out prevention mechanism 70 utilize the component parts included in the conventional card connector, and therefore can be formed at the same time when the conventional component parts are manufactured. In addition, since the structure is simple, the assembly is easy, and the manufacturing time is reduced as compared with the conventional card connector as a whole, and the manufacturing cost is also reduced.

  The operation of removing the IC card 100 attached to the card connector 10 from the card connector 10 having the above-described configuration will be described in detail below with reference to FIGS.

  FIG. 3A shows a state where the IC card 100 is attached to the card connector 10. In the state shown in FIG. 3A, the tip 101 of the IC card 100 is located in the vicinity of the front wall 23, and the card recognition switch 28 is in the on state. A plurality of pads (not shown) as external contacts of the IC card 100 are electrically connected to the corresponding contacts 40. Further, the eject member 51 constituting the eject mechanism 50 resists the urging force of the coil spring 55 in accordance with the insertion operation of the IC card 100 when the tip portion 101 of the IC card 100 abuts against the card abutment portion 56. It is pushed forward and reaches the vicinity of the front wall 23. Similarly, a leg portion provided at the front end of the cam lever 54 constituting the ejection mechanism 50 is engaged with a concave portion of the hard cam 52, whereby the ejection member 51 is held in this position. Further, the claw portion 57 of the eject member 51 constituting the card pop-out prevention mechanism 70 is engaged with the notch recess 103 of the IC card 100. Therefore, the IC card 100 is held at the position shown in FIG. Further, the small protrusions 26 provided on the base member 20 constituting the card pop-out prevention mechanism 70 are formed in the elongated cutout grooves 58 provided on the eject member 51 as shown in FIGS. 3 (a) and 3 (b). And is not located in the notch groove 58.

  Next, in the state of FIG. 3A, the IC card 100 is fully pushed forward. Thereby, the eject member 51 also moves forward. Accordingly, the leg portion provided at the front end of the cam lever 54 is guided by the guide groove 53 and the engagement with the concave portion of the heart cam 52 is released. Immediately after that, when the pushing into the IC card 100 is released, the eject member 51 moves toward the initial position shown in FIG. 4A by the urging force of the coil spring 55. Finally, the eject member 51 is returned to a position where the rear end of the eject member 51 which is the initial position contacts the step portion 22a of the right side wall 22 of the base member 20, and the eject operation is completed. At this time, as described above, the eject member 51 is in a rotatable state with the first pin 61 as the center of rotation (see also FIG. 5).

  At the same time, the IC card 100 is also positioned at an intermediate position shown in FIG. 4A (a position where about half of the length of the IC card 100 protrudes backward from the card insertion slot 24 through the card abutting portion 56 of the eject member 51. ). However, since the claw portion 57 of the eject member 51 is engaged with the cutout recess 103 of the IC card 100, the IC card 100 is braked and stops at this intermediate position. Therefore, the IC card 100 does not jump out of the card insertion slot 24 due to inertial force. Even if the inertial force applied to the IC card 100 is large, the brake force described later further acts, so that the IC card 100 is surely stopped once at this position.

  In the state shown in FIG. 4A, when the eject member 51 returns to the initial position, the small protrusion 26 is positioned in the elongated notch groove 58 of the eject member 51 as shown in FIG. 4B. .

  For example, after the IC card 100 in a stopped state as shown in FIG. 4A is gripped by the fingertip of the rear end portion of the IC card 100, the IC card 100 is pulled out from the card connector 10. At this time, since the front of the claw portion 57 of the eject member 51 is formed as an inclined surface, the pulling force to the rear of the IC card 100 rotates the eject member 51 clockwise with the other end of the coil spring 55 as the rotation center. Acts as a force to cause Thereby, as shown in FIG. 6A, the claw portion 57 of the eject member 51 can be detached from the notch recess 103 of the IC card 100.

  By the way, as shown in FIG. 6B, the small protrusions 26 of the base member 20 in the elongated notch groove 58 of the eject member 51 abut on the elongated notch groove 58 by the rotation of the eject member 51, and the eject member Interfering with the rotation of 51. More specifically, the clockwise rotation of the eject member 51 causes the side surface 58A of the notch groove 58 to contact the side surface 26A of the small protrusion 26, and the inclined surface 58a of the side surface 58A rides on the inclined surface 26a of the side surface 26A. Thus, the rotation of the eject member 51 is braked. Thereby, the claw portion 57 of the eject member 51 is prevented from being easily detached from the cutout recess 103 of the IC card 100.

  As described above, the card pop-out preventing mechanism 70 is configured to prevent the IC card 100 from being easily popped out of the card connector 10 by the inertial force applied by the eject mechanism 50. Furthermore, the IC card 100 can be reliably removed from the card connector by causing the user to consciously pull out the IC card 100 from the card connector 10.

  When the IC card 100 is completely removed from the card connector from the state shown in FIG. 6A, the eject member 51 is kept on the small protrusion 26. Therefore, when the IC card 100 is next inserted, the IC card 100 inserted from the card insertion slot 24 can be easily kept until the tip 101 of the IC card 100 contacts the card contact portion 56 of the eject member 51. Can be inserted into. Then, when the tip 101 of the IC card 100 abuts against the card abutting portion 56 and the card abutting portion 56 is pushed, the eject member 51 rotates counterclockwise around the first pin 61 as the center of rotation. To do. Thereby, the claw portion 57 of the eject member 51 is engaged with the notch recess 103 of the inserted IC card 100. Subsequently, the IC card 100 is pushed into the card housing space against the urging force of the coil spring 55 together with the eject member 51 and brought into the state shown in FIG. To do.

The card connector which concerns on this invention is shown, (a) is a top view of a card connector in the state from which the cover member was removed, (b) is a top view of a cover member. It is a top view of the card connector in a state where an IC card is mounted.
