  Further, a first leaf spring member 34a as an inner shell urging member having an elongated belt-like shape extending further downward in the forward direction at the lower ends of the first tip wall portion 33c and the second tip wall portion 33d, and The second leaf spring members 34b are connected to each other. Here, the first plate spring member 34a and the second plate spring member 34b function as a cantilever having elasticity, and the tip which is a free end protrudes below the pressure receiving portion 32, and the front edge of the bottom wall portion 11a. It comes in contact with the upper surface of the side portion. Therefore, as shown in FIG. 2, in the initial state in which the inner shell 31 is attached to the housing 11, the inner shell 31 is lifted by being biased upward by the first leaf spring member 34a and the second leaf spring member 34b. Thus, the back surface of the pressure receiving portion 32 is separated from the upper surface of the portion near the front edge of the bottom wall portion 11a. In the initial state, the front end edge of the pressure receiving portion 32 is located at a height substantially equal to the rear end edge of the gate portion 22 of the changer 21. Also, in the front-rear direction, the gap between the front end edge of the pressure receiving portion 32 and the rear end edge of the gate portion 22 is extremely narrow. Further, although not shown, the lower surfaces of the first engagement piece 35a and the second engagement piece 35b are also separated from the upper ends of the notches of the inner shell first engagement portion 11i and the inner shell second engagement portion 11j. ing.

  In the initial state, the distance between the back surface of the pressure receiving portion 32 and the upper surface of the portion near the front edge of the bottom wall portion 11a is shorter than the vertical dimension of the first card 51a, and the vertical dimension of the second card 51b. Is set to be approximately equal to or slightly longer. That is, the thickness of the gap between the back surface of the pressure receiving portion 32 and the upper surface of the portion near the front edge of the bottom wall portion 11a is smaller than the thickness of the first card 51a and is substantially equal to or slightly equal to the thickness of the second card 51b. It is thick. Therefore, the second card 51b can be inserted into the gap between the back surface of the pressure receiving portion 32 in the initial state and the upper surface of the portion near the front edge of the bottom wall portion 11a. In this case, the pressure receiving part 32 functions as a top plate of the passage into which the second card 51b is inserted. The inner shell 31 is prevented from moving upward from the position shown in FIG. 2 because the upward movement is restricted by the shell 12 attached to the housing 11. That is, in the initial state, the inner shell 31 is located on the upper side.

  Further, since the inner shell 31 is lifted up and biased upward by the first leaf spring member 34a and the second leaf spring member 34b, the first leaf spring member 34a and the second leaf spring member 34b. When a downward force that overcomes the urging force is applied, it moves downward. When the inner shell 31 is located at the bottom dead center, the distance between the upper surface of the pressure receiving portion 32 and the lower surface of the top plate of the shell 12 is substantially equal to or slightly longer than the vertical dimension of the first card 51a. Is set to about. That is, the thickness of the gap between the upper surface of the pressure receiving portion 32 and the lower surface of the top plate of the shell 12 is approximately equal to or slightly thicker than the thickness of the first card 51a. Therefore, the first card 51 a can be inserted into the gap between the upper surface of the pressure receiving portion 32 moved downward and the lower surface of the top plate of the shell 12. In this case, the pressure receiving part 32 functions as a bottom plate of the passage into which the first card 51a is inserted. The first side wall 33a and the second side wall 33b are set so that the distance between them is substantially equal to or slightly wider than the width of the first card 51a, and functions as guides on both sides of the first card 51a.

  Next, the configuration of the cam slider 41 will be described in detail.

  7 is a perspective view of the cam slider according to the embodiment of the present invention as viewed from above, FIG. 8 is a perspective view of the cam slider according to the embodiment of the present invention as viewed from below, and FIG. 9 is according to the embodiment of the present invention. It is a perspective view which shows a lock terminal.

  As shown in FIG. 7, the cam slider 41 includes a slider member 42 that is integrally formed of an insulating material such as a synthetic resin, and a lock terminal 43 that is an elongated strip-shaped member made of a metal plate material. The slider member 42 has a thick first block portion 42a formed at the rear end (upper right end in FIG. 7) of an elongated rectangular plate-like main body portion extending in the front-rear direction, and the first block portion. It has the 2nd block part 42c thinner than 42a.

  The first block portion 42a is a side surface perpendicular to the upper surface of the main body portion, and is a surface that is perpendicular to the major axis direction of the main body portion and faces forward (lower left in FIG. 7). A first abutting portion 42b is provided as a first engaging portion made of a surface extending in the front oblique direction. The first butting portion 42b has a shape corresponding to the shape of the left corner at the distal end in the insertion direction of the first card 51a, and the left corner at the distal end in the insertion direction of the first card 51a inserted into the card connector 10. The front surface and the side surface of the part abut.

  The second block portion 42c is a first card as an erroneous insertion preventing surface which is a side surface perpendicular to the upper surface of the main body portion and is a surface perpendicular to the major axis direction of the main body portion and facing forward. For erroneous insertion prevention part 42d is provided. When the first card 51a is inserted upside down or in the reverse direction, the first card 51a erroneous insertion prevention protrusion 11r contacts the first card 51a and cannot move forward. Since the 1-card erroneous insertion preventing portion 42d prevents the first card 51a from moving forward, the first contact portion 15a is not damaged. It should be noted that the first card erroneous insertion preventing portion 42d is in a state in which the rear end of the slider member 42 is in contact with the rear wall portion 11b of the housing 11 and the slider member 42 cannot move further back. Or the function which prevents the advance of the 1st card | curd 51a inserted in the front-back direction is fully exhibited. Moreover, since the recessed part of the shape corresponding to the 2nd block part 42c is formed in the back surface of the left corner | angular part in the insertion direction front-end | tip of the 1st card | curd 51a, the 1st card | curd 51a was inserted in the correct direction. In this case, the second block part 42c is accommodated in the recess.

  Further, the slider member 42 has a protruding portion 42e protruding forward from the front end of the main body portion. The slider member 42 is a side surface perpendicular to the upper surface of the main body portion in a cutout portion formed on the side of the projecting portion 42e, and is a surface perpendicular to the major axis direction of the main body portion and facing forward. A second abutting portion 42f as a second engaging portion is provided. The second abutting portion 42f is in contact with the lower portion of the front surface of the left corner at the leading end of the second card 51b in the insertion direction. Further, the slider member 42 is a second engaging portion which is a side surface perpendicular to the upper surface of the main body at the tip of the projecting portion 42e, and is a surface perpendicular to the major axis direction of the main body and facing forward. As a third abutting portion 42h. The third abutting portion 42h comes into contact with the inner surface of the recess formed on the back surface of the left corner at the leading end of the second card 51b in the insertion direction.

  The third abutting portion 42h also functions as a second card erroneous insertion preventing portion. When the second card 51b is inserted in the front or back direction or the front-reverse direction, when the second card erroneous insertion preventing projection 11s of the housing 11 abuts against the second card 51b, the forward movement cannot be prevented. Since the three abutting portions 42h prevent the second card 51b from moving forward, the second contact portion 15b is not damaged. Note that the third abutting portion 42h has a rear end or a front-rear reverse in a state where the rear end of the slider member 42 is in contact with the rear wall portion 11b of the housing 11 and the slider member 42 cannot move further rearward. The function of preventing the advance of the second card 51b inserted in the direction is sufficiently exhibited.

  The slider member 42 has a cam block portion 42i formed on the side of the first block portion 42a at the rear end of the main body portion. The cam block portion 42i includes a cam groove 42q formed on the upper surface, and pushes / pushes the slider member 42 that moves together with the card 51 by cooperating with the pin member 44 engaged with the cam groove 42q. It is supposed to perform the operation. The pin member 44 has one end engaged with the cam groove 42q and the other end engaged with the rear wall portion 11b of the housing 11. Further, since a cam mechanism for performing a push / push operation like the cam block portion 42i is well known in the art, description thereof is omitted. Further, a locking portion 42p for locking one end of the urging member 45 is formed at the front end of the cam block portion 42i.

  As shown in FIG. 9, the lock terminal 43 includes an elongated belt-like main body portion 43a extending in the front-rear direction, and an elongated cantilever-like first lever portion extending forward from the rear end portion of the main body portion 43a. 43b and an elongated cantilevered second lever portion 43c extending further forward from the front end portion of the main body portion 43a. The first lever portion 43b is bent so as to be substantially perpendicular to the main body portion 43a, and is parallel to the upper surface of the main body portion of the slider member 42. Further, a first locking action portion 43d that protrudes upward is formed at the front end of the first lever portion 43b, and a second protrusion that protrudes laterally, for example, in a mountain shape, at the front end of the second lever portion 43c. A lock action portion 43e is formed. In addition, since the 1st lever part 43b and the 2nd lever part 43c function as a cantilever provided with elasticity, the 1st lock action part 43d and the 2nd lock action part 43e can be elastically displaced. Further, a first press-fit protrusion 43g and a second press-fit protrusion 43f that protrude upward are connected to the rear end and the side surface of the first lever portion 43b in order to engage with the slider member 42.

  As shown in FIG. 8, a lock terminal accommodating recess 42 k is formed on the back surface of the slider member 42. The lock terminal 43 is configured such that a part of the first lever portion 43 b and the main body portion 43 a accommodate the lock terminal. The slider member 42 is attached so as to be accommodated in the recess 42k. The first block portion 42a and the second block portion 42c of the slider member 42 are respectively formed with a first press-fit recess 42m and a second press-fit recess 42n, and the lock terminal 43 includes the first press-fit projection 43g and the second press-fit projection 43g. The press-fitting protrusion 43f is fixed to the slider member 42 by being press-fitted and locked in the first press-fitting recess 42m and the second press-fitting recess 42n, respectively. Further, a lock opening 42j is formed in the main body portion of the slider member 42, and the first lock action portion 43d is accommodated in the lock opening 42j so as to protrude upward from the upper surface of the main body portion. Yes.

  Here, since the first locking action portion 43d is biased by the elastic force of the first lever portion 43b, the first card inserted into the card connector 10 can be elastically displaced in the vertical direction. It is possible to engage with an engaging recess formed at the left end near the front end in the insertion direction on the back surface of 51a. The engaging recess has an opening continuous from the back surface to the left side of the first card 51a, and the first locking action portion 43d protruding upward is engaged with the opening on the back surface of the first card 51a. It enters into the joint recess and engages. The first locking action portion 43d is engaged with the engaging recess in a state where the front surface and the side surface of the left corner at the distal end in the insertion direction of the first card 51a are in contact with the first abutting portion 42b. Yes. Thereby, the cam slider 41 can hold | maintain the 1st card | curd 51a and can move to the front-back direction with this 1st card | curd 51a.

  Further, since the second locking action portion 43e is biased by the elastic force of the second lever portion 43c, it can be elastically displaced in the left-right direction, and the second card 51b inserted into the card connector 10 is inserted. It is possible to engage with a recess for engagement formed at the left end in the vicinity of the front end in the insertion direction on the back surface. The engaging recess has an opening continuous from the back surface to the left side of the second card 51b, and the second locking action portion 43e protruding sideways extends from the opening on the left side of the second card 51b to the engaging recess. Enter and engage. The second locking action portion 43e is formed on the back surface of the left corner at the distal end in the insertion direction, with the lower part of the front surface of the left corner at the distal end in the insertion direction of the second card 51b contacting the second abutting portion 42f. The inner surface of the recessed portion is engaged with the engaging recessed portion in contact with the third abutting portion 42h. Thereby, the cam slider 41 can hold | maintain the 2nd card | curd 51b, and can move to the front-back direction with this 2nd card | curd 51b.

  The biasing member 45 whose one end is locked to the cam slider 41 biases the cam slider 41 in a direction opposite to the insertion direction of the card 51, that is, forward. The cam slider 41 moves the card 51 from the terminal point by the urging force of the urging member 45 when the card 51 moves in the inserting direction and reaches the terminal point by a push operation of pushing the card 51 in the inserting direction. Move in the direction opposite to the insertion direction.

  In the push operation for loading the card 51 into the card connector 10, the cam slider 41 moves with the card 51 by receiving a force applied to the card 51 by a user's finger or the like, and moves in the card connector 10. It is moved toward the rear wall portion 11b, reaches the terminal point that is the most advanced position, and enters a full stroke state. Subsequently, when the force applied to the card 51 by the user is released, the cam slider 41 and the card 51 receive the repulsive force of the urging member 45 and are separated from the rear wall portion 11b, that is, the card connector. It is moved toward 10 insertion openings. Then, the cam slider 41 and the card 51 stop at a lock position where the card 51 is held in the card connector 10 in a locked state. As a result, the card 51 is loaded at a predetermined position in the card connector 10.

  In the push operation for ejecting the card 51 from the card connector 10, the cam slider 41 receives a force applied to the card 51 by a user's finger or the like, so that the card connector together with the card 51 from the lock position. 10 is moved toward the rear wall portion 11b, reaches the terminal point that is the most advanced position, and becomes a full stroke state. Subsequently, when the force applied to the card 51 by the user is released, the cam slider 41 and the card 51 are moved toward the insertion opening of the card connector 10 by receiving the repulsive force of the urging member 45. . Then, it passes through the lock position and further moves in the direction opposite to the insertion direction of the card 51. As a result, the card 51 is ejected from the card connector 10.

  The operation of the cam slider 41 in such a push operation is the same whether the card 51 is the first card 51a or the second card 51b. That is, the cam slider 41 is a device shared by the first card 51a and the second card 51b.

  By the way, in the lock position, it is desirable to strengthen the function of the cam slider 41 to hold the card 51 so that the loaded card 51 does not deviate from the lock position, that is, the card 51 is locked.

  Here, when the card 51 is the first card 51a, strengthening the function of the cam slider 41 held by the first card 51a strengthens the elastic force of the first lever portion 43b, and the first locking action portion. This can be realized by increasing the force with which 43d is engaged with the engaging recess of the first card 51a. And strengthening the elastic force of the 1st lever part 43b is realizable by shortening the free length of the 1st lever part 43b. Therefore, a member for partially restricting the downward displacement of the first lever portion 43b at the location of the housing 11 corresponding to the back side of the first lever portion 43b when the cam slider 41 is in the locked position, for example, It is desirable to dispose a member such as a protrusion that contacts the back side of the intermediate portion of the first lever portion 43b.

  Further, when the card 51 is the second card 51b, strengthening the function of the cam slider 41 held by the second card 51b strengthens the elastic force of the second lever portion 43c, and the second locking action portion 43e This can be realized by increasing the force of engaging with the engaging recess of the second card 51b. Further, increasing the elastic force of the second lever portion 43c can be realized by shortening the free length of the second lever portion 43c. Therefore, a member for partially restricting the leftward displacement of the second lever portion 43c at the location of the housing 11 corresponding to the back side of the second lever portion 43c when the cam slider 41 is in the locked position, for example, It is desirable to dispose a member such as a protrusion that contacts the back side of the intermediate portion of the second lever portion 43c.

  Thereby, in the lock position, the function that the cam slider 41 holds the card 51 is strengthened, and the card 51 is locked. Even when the card 51 is locked, the first locking action portion 43d and the second locking action portion 43e can be displaced, so that the user can use the card 51 for the card with a stronger force than usual. When an attempt is made to pull out toward the insertion opening of the connector 10, the holding of the card 51 is released. That is, forcible removal of the card 51 is allowed. Further, when the cam slider 41 is at a position other than the lock position, the cam slider 41 always holds the card 51 with a certain holding force. That is, the temporary holding function is exhibited. Therefore, even when the card 51 is ejected from the card connector 10 by the push operation for ejecting from the card connector 10, the card 51 is held by the cam slider 41. It will not fly out. Since the ejected card 51 is only temporarily held, when the user removes the card from the card connector 10 with fingers or the like, it is not necessary to apply force and can be easily removed.

  Here, the first lever portion 43b is bent so as to be substantially perpendicular to the main body portion 43a, and the first lever portion 43b and the second lever portion 43c extend on two planes orthogonal to each other, The lock terminal 43 formed so that the protrusion direction and the displacement direction of the first lock action portion 43d and the protrusion direction and the displacement direction of the second lock action portion 43e are orthogonal to each other has been described. The first lever portion 43b and the second lever portion 43c extend on two parallel planes, the protruding direction and the displacement direction of the first locking action portion 43d, and the protruding direction and the displacement direction of the second locking action portion 43e. May be formed so as to be in the same direction. Furthermore, although the case where the lock terminal 43 is a member formed separately from the slider member 42 has been described, the lock terminal 43 may be formed integrally with the slider member 42. For example, the slider member 42 and the lock terminal 43 can be integrally formed of metal or synthetic resin.

  Next, the operation of the card connector 10 having the above configuration will be described. First, the operation when the first card 51a is inserted will be described.

  FIG. 10 is a side view showing a state before a card having a large outer dimension is inserted into the card connector in the embodiment of the present invention, and FIG. 11 is a diagram showing a card having a large outer dimension in the card connector in the embodiment of the present invention. FIG. 12 is a first side view showing a state in the middle of insertion, FIG. 12 is a second side view showing a state in the middle of inserting a card having a large external dimension into the card connector in the embodiment of the present invention, and FIG. FIG. 14 is a third side view showing a state in the middle of inserting a card having a large external dimension into the card connector in the embodiment of the invention, and FIG. 14 shows a card having a large external dimension to the card connector in the embodiment of the present invention. It is a top view which shows the state which loading was completed.

  10 to 14 show a state in which the shell 12 is removed for the purpose of explanation. Moreover, FIGS. 10-13 has shown the cross section partially. FIG. 10 shows a state immediately before the first card 51a is inserted in front of the insertion opening of the card connector 10. In the illustrated example, it is assumed that the first card 51a is not in the front-back or front-reverse direction but in an appropriate direction with respect to the card connector 10. That is, the first card 51a is in such a posture that a card-side connection terminal (not shown) is positioned on the lower surface near the right end in FIG. From FIG. 10, it can be seen that a first chamfered portion 52a as a chamfered portion is formed at the lower end edge of the leading end of the first card 51a in the insertion direction. In the illustrated example, the first chamfered portion 52a is an inclined plane that is inclined rearward and downward from the distal end in the insertion direction, and extends in the width direction of the first card 51a. The first chamfered portion 52a may be a surface of any shape as long as it smooths the corner of the lower end edge at the leading end of the first card 51a extending in the width direction. A curved surface called a so-called R-plane may also be used.

  In this case, the card connector 10 is in the initial state, the shutter plate 13 (not shown in FIG. 10) is urged by the shutter spring to close the insertion opening, and the gate portion 22 of the changer 21 is changed to the changer spring 27. The pressure receiving portion 32 of the inner shell 31 is urged by the first leaf spring member 34a and the second leaf spring member 34b, and is in an initial position inclined obliquely downward toward the rear wall portion 11b of the housing 11. Thus, it is in an initial position where it is lifted to a height equal to the rear edge of the gate portion 22.

  Subsequently, the first card 51a is moved toward the rear wall portion 11b of the card connector 10, and the state in which the vicinity of the front end in the insertion direction of the first card 51a is inserted into the card housing space of the card connector 10 from the insertion opening. It is shown in FIG. In this state, the leading end of the first card 51 a in the insertion direction is located immediately before the leading edge of the gate portion 22 of the changer 21. Further, the first stopper protrusion 26a and the second stopper protrusion 26b of the changer 21 are in contact with both side surfaces of the first card 51a so that the distance between them is widened, and the card back first guide portion 11m of the housing 11 and the card The first stopper accommodating recess 11p and the second stopper accommodating recess 11q formed on the upper surface of the rear surface second guide portion 11n are displaced to the upper side. That is, the stopper is released. The back surface of the first card 51a is guided in contact with the top surfaces of the card back surface first guide portion 11m and the card back surface second guide portion 11n, and both side surfaces of the first card 51a are connected to the card side first guide wall 11t. And the card side second guide wall 11u.

  Subsequently, when the first card 51a is further moved toward the rear wall portion 11b of the card connector 10, the upper end edge of the insertion end of the first card 51a comes into contact with the gate portion 22 inclined obliquely downward, The gate portion 22 is pressed upward. In this case, since the stopper is released and the changer 21 is in a swingable state, when the pressing force applied from the first card 51a to the gate portion 22 overcomes the urging force of the changer spring 27, the changer 21 Swings and the gate part 22 moves upward, so that the first card 51a can pass under the gate part 22. The first card 51a is guided by the back surface being in contact with the top surfaces of the card back surface first guide portion 11m and the card back surface second guide portion 11n, so that the first card 51a may be lowered even if it receives a reaction force from the gate portion 22. There is no movement. Further, as the changer 21 swings, the first stopper protrusion 26a and the second stopper protrusion 26b are respectively housed in the first stopper housing recess 11p and the second stopper housing recess 11q and move downward. At this time, the upward movement of the first card 51a is restricted by the gate portion 22, and the first card 51a is urged from above.

  Subsequently, when the first card 51 a is further moved toward the rear wall portion 11 b of the card connector 10, the first chamfered portion 52 a at the distal end in the insertion direction of the first card 51 a becomes the front end of the pressure receiving portion 32 of the inner shell 31. Abut against the edge. Here, at least the upper end of the first chamfered portion 52a is at a position higher than the position of the pressure receiving portion 32 in the initial position. When the first card 51a is moved in a state where the first chamfered portion 52a is in contact with the front end edge of the pressure receiving portion 32, the first chamfered portion 52a is inclined rearward and downward. A pressing force pressing downward is generated. The first card 51a is guided by the upper surface being in contact with the back surface of the gate portion 22, so that it does not move upward even when the reaction force from the pressure receiving portion 32 is received. Then, when the pressing force applied from the first card 51a to the pressure receiving portion 32 overcomes the urging force of the first plate spring member 34a and the second plate spring member 34b, the pressure receiving portion 32 is moved as shown in FIG. The first card 51a can pass above the pressure receiving portion 32 by moving downward. That is, the gap dimension in the thickness direction of the first card 51a between the rear end edge of the gate portion 22 and the front end edge of the pressure receiving portion 32 is smaller than the thickness dimension of the first card 51a. By configuring in this way, erroneous insertion can be prevented as will be described later.

  Subsequently, when the first card 51a is further moved toward the rear wall portion 11b of the card connector 10, as shown in FIG. 13, the first card 51a has a pressure receiving portion whose back surface is moved downward. It abuts on the upper surface of 32 and is guided. In this case, a gap is formed between the back surface of the pressure receiving portion 32 and the upper surface of the housing 11 near the front edge of the bottom wall portion 11a, and the second contact portion 15b is located in the gap. However, the inner shell 31 is located at the bottom dead center, and the first engagement piece 35 a and the second engagement piece 35 b are connected to the inner shell first engagement portion 11 i and the inner shell second engagement portion 11 j of the housing 11. Since it is engaged, the pressure receiving part 32 does not move further downward. Therefore, the second contact portion 15b is not strongly pressed downward by the pressure receiving portion 32 or the first card 51a. Further, since the pressure receiving portion 32 is interposed therebetween, the second contact portion 15b does not contact the back surface of the first card 51a when the first card 51a passes over the pressure receiving portion 32. Therefore, it can prevent that the 2nd contact part 15b interferes with the back surface of the 1st card | curd 51a, and the 2nd contact part 15b is not damaged.

  Subsequently, when the first card 51 a is further moved toward the rear wall portion 11 b of the card connector 10, the front and side surfaces of the left corner at the front end in the insertion direction of the first card 51 a are the first abutting portions of the cam slider 41. The engaging recess formed in the left end near the front end in the insertion direction on the back surface of the first card 51a engages with the first locking action portion 43d of the cam slider 41. As a result, the first card 51 a is temporarily held by the cam slider 41 and moves together with the cam slider 41. In this case, the first card erroneous insertion prevention projection 11r is disposed at a position immediately before the first contact portion 15a of the bottom wall portion 11a, but is inclined rearward and downward at the distal end in the insertion direction of the first card 51a. Since the first chamfered portion 52a is in contact with the first card erroneous insertion preventing projection 11r, the first card 51a can smoothly ride on the first card erroneous insertion preventing projection 11r. Can move without receiving resistance.

  Subsequently, when the first card 51a is further moved toward the rear wall portion 11b of the card connector 10, the cam slider 41 moves together with the first card 51a, reaches the terminal point that is the most advanced position, and reaches the full position. Stroke state.

  Subsequently, when the force to move the first card 51a toward the rear wall portion 11b of the card connector 10 is released, the cam slider 41 and the first card 51a receive the repulsive force of the urging member 45 and receive the rear wall. It is moved toward the direction away from the portion 11b, that is, toward the insertion opening of the card connector 10. Then, the cam slider 41 and the first card 51a are stopped at the lock position where the first card 51a is held in the card connector 10 while being locked. As a result, the first card 51a is loaded at a predetermined position in the card connector 10 as shown in FIG. In a state in which the first card 51a is loaded in the card connector 10, the first contact portion 15a of the terminal 15 contacts the card side connection terminal disposed on the back surface near the front end in the insertion direction of the first card 51a. Are electrically connected. Further, since the cam slider 41 is at the lock position, the card 51 is locked by the cam slider 41 and is prevented from moving in the front-rear direction.

  As described above, when the first card 51a is inserted into the card housing space of the card connector 10, the changer 21 swings by identifying that the inserted card 51 is the first card 51a having a large external dimension. The first card 51a is distributed to the upper side in the card accommodation space, and is passed through the upper passage of the inner shell 31. In this case, the inner shell 31 serves as the bottom plate of the upper passage, defines the passage of the first card 51a, and prevents damage to the second contact portion 15b.

  Further, when taking out the first card 51 a loaded in the card connector 10, the first card 51 a is moved toward the rear wall portion 11 b of the card connector 10. The cam slider 41 moves together with the first card 51a, reaches the terminal point that is the most advanced position, and enters a full stroke state.

  Subsequently, when the force to move the first card 51a toward the rear wall portion 11b of the card connector 10 is released, the cam slider 41 and the first card 51a receive the repulsive force of the biasing member 45, and the card The connector 10 is moved toward the insertion opening of the connector 10. Then, the cam slider 41 stops when it returns to the initial position shown in FIGS. In this case, since the first card 51a is temporarily held by the cam slider 41, the first card 51a stops together with the cam slider 41 and does not fly out of the card connector 10 due to inertia. Since the first card 51a is only temporarily held, it is not necessary to apply a force when the user pulls it out toward the insertion opening with fingers or the like and can be easily taken out from the card connector 10.

  In this case, as the first card 51a moves toward the insertion opening, the changer 21 and the inner shell 31 return to the initial position by performing the reverse operation to the case where the first card 51a is inserted. In addition, when the user forcibly pulls out the first card 51a locked by the cam slider 41 loaded in the card connector 10 from the card connector 10 with a force stronger than usual, Even when the first card 51a is forcibly removed, the changer 21 and the inner shell 31 operate in the reverse manner to the case where the first card 51a is inserted as the first card 51a moves toward the insertion opening. To return to the initial position.

  Next, the operation when the first card 51a is inserted in the front-back or front-back direction, that is, when it is erroneously inserted will be described. In addition, description is abbreviate | omitted about the operation | movement same as the operation | movement in the case of inserting the 1st card | curd 51a which has the appropriate direction mentioned above.

  Even when the first card 51a is moved toward the rear wall portion 11b of the card connector 10, the changer 21 swings and the gate portion 22 moves upward, One card 51 a can pass under the gate portion 22. However, when the first card 51 a is further moved toward the rear wall portion 11 b of the card connector 10, a surface other than the first chamfered portion 52 a, that is, a vertical surface extending in the vertical direction is formed on the inner shell 31. The pressure receiving portion 32 comes into contact with the front end edge. Therefore, the first card 51a is prevented from moving forward by the pressure receiving portion 32, and cannot move further toward the rear wall portion 11b, and the first contact portion 15a and the second contact portion 15b may be damaged. Absent. In this case, even if the force for inserting the first card 51a is strong, the entire inner shell 31 receives the force from the first card 51a in the front-rear direction, so the pressure receiving portion 32 functions as a robust erroneous insertion prevention member. . In this manner, the pressure receiving portion 32 of the inner shell 31 functions as an erroneous insertion preventing member, and erroneous insertion of the first card 51a is prevented. The front end edge of the pressure receiving portion 32 forms a curved end side 32b that is recessed with respect to both end portions so that the central portion is retracted toward the rear wall portion 11b. This is because when the pressure receiving portion 32 is deformed so as to protrude from the flat shape and protrude upward or downward, that is, when the pressure receiving portion 32 is warped, the central portion of the front end edge of the pressure receiving portion 32 is appropriately first. This is because it is considered that the card 51a may not come into contact with the card 51a.

  However, it is also conceivable that the pressure receiving part 32 moves downward due to some cause and the first card 51a passes above the pressure receiving part 32. Also in this case, since the pressure receiving portion 32 is interposed therebetween, the second contact portion 15b is not damaged when the first card 51a passes above the pressure receiving portion 32. However, when the first card 51a is further moved toward the rear wall portion 11b of the card connector 10, the vertical surface extending in the vertical direction other than the first chamfered portion 52a is the first contact of the bottom wall portion 11a. The first card erroneous insertion preventing protrusion 11r disposed at a position immediately before the portion 15a will abut. Therefore, the first card 51a is prevented from moving forward by the first card erroneous insertion preventing projection 11r and cannot move further toward the rear wall portion 11b, and the first contact portion 15a and the second contact portion 15b is not damaged. In this manner, the first card erroneous insertion preventing protrusion 11r functions as an erroneous insertion preventing member, thereby preventing erroneous insertion of the first card 51a.

  However, for some reason, the first card 51a can ride on the erroneous insertion prevention protrusion 11r for the first card and further move. However, in this case, the first card erroneous insertion preventing portion 42d of the cam slider 41 prevents the first card 51a from moving forward, so that the first contact portion 15a is not damaged. In this manner, the first card erroneous insertion preventing portion 42d functions as an erroneous insertion preventing member, and erroneous insertion of the first card 51a is prevented. Note that the first card erroneous insertion preventing portion 42d has the rear end of the cam slider 41 in contact with the rear wall portion 11b of the housing 11 so that the cam slider 41 cannot be moved further rearward or front / back or front / rear. The function of preventing the advance of the first card 51a inserted in the reverse direction is sufficiently exhibited.

  As described above, the pressure receiving portion 32 of the inner shell 31, the erroneous insertion prevention protrusion 11r for the first card, and the erroneous insertion prevention portion 42d for the first card of the cam slider 41 exhibit functions for preventing erroneous insertion. It is possible to reliably prevent the inserted first card 51a from moving forward.

  Next, the operation when the second card 51b is inserted will be described.

  FIG. 15 is a side view showing a state before a card having a small outer dimension is inserted into the card connector in the embodiment of the present invention. FIG. 16 is a diagram showing a card having a small outer dimension in the card connector according to the embodiment of the present invention. 17 is a first side view showing a state in the middle of insertion, FIG. 17 is a second side view showing a state in the middle of inserting a card having a small outer dimension into the card connector in the embodiment of the present invention, and FIG. It is a side view which shows the state which loading of the card | curd with a small external dimension to the connector for cards in embodiment of invention was completed.

  15 to 18 show a state in which the shell 12 is removed for the sake of explanation, and partially show a cross section. In the illustrated example, it is assumed that the second card 51b is in an appropriate orientation with respect to the card connector 10 and not in the front-back or front-back direction. That is, the second card 51b is in such a posture that a card-side connection terminal (not shown) is positioned on the lower surface near the right end in FIG. From FIG. 15, it can be seen that a second chamfered portion 52b as a chamfered portion is formed at the lower end edge of the leading end of the second card 51b in the insertion direction. In the illustrated example, the second chamfered portion 52b is an inclined plane that is inclined rearward and downward from the distal end in the insertion direction, and extends in the width direction of the second card 51b. The second chamfered portion 52b may be a surface having any shape as long as it smooths the corner of the lower end edge at the leading end of the second card 51b extending in the width direction. A curved surface called a so-called R-plane may also be used.

  In this case, the card connector 10 is in an initial state, similar to the state shown in FIG. 10, and the shutter plate 13 is urged by the shutter spring to close the insertion opening, and the gate portion of the changer 21 Reference numeral 22 denotes an initial position which is biased by the changer spring 27 and is inclined obliquely downward toward the rear wall portion 11b of the housing 11. The pressure receiving portion 32 of the inner shell 31 is a first plate spring member 34a and a second plate spring member. It is in the initial position where it is urged by 34b and lifted to the same height as the rear edge of the gate portion 22.

  Subsequently, the second card 51b is moved toward the rear wall portion 11b of the card connector 10, and the state in which the vicinity of the front end in the insertion direction of the second card 51b is inserted into the card housing space of the card connector 10 from the insertion opening. It is shown in FIG. In this state, the leading end of the second card 51b in the insertion direction is located immediately before the leading edge of the gate portion 22 of the changer 21. The width of the second card 51b is narrower than the distance between the first stopper protrusion 26a and the second stopper protrusion 26b in the initial state. Therefore, the first stopper protrusion 26a and the second stopper protrusion 26b of the changer 21 are not in contact with both side surfaces of the second card 51b and remain in the initial state. That is, the stopper is not released. The back surface of the second card 51b is guided in contact with the upper surface of the bottom wall portion 11a near the front edge, and both side surfaces of the second card 51b are the card side first guide portion 11v and the card side surface second. Guided by the guide portion 11w.

  Subsequently, when the second card 51b is further moved toward the rear wall portion 11b of the card connector 10, the second card 51b moves without contacting the gate portion 22, and as shown in FIG. The leading end in the insertion direction is below the rear end edge of the gate portion 22 and reaches a position immediately before the front end edge of the pressure receiving portion 32 of the inner shell 31. Since the distance between the rear end edge of the gate portion 22 in the initial state and the upper surface of the portion near the front edge of the bottom wall portion 11a is substantially equal to or slightly thicker than the thickness of the second card 51b, the second card 51b It can move without contacting the gate part 22. Further, the distance between the back surface of the pressure receiving portion 32 of the inner shell 31 and the upper surface of the portion near the front edge of the bottom wall portion 11a in the initial state is substantially equal to or slightly thicker than the thickness of the second card 51b.

  However, when the second card 51b is moved relatively upward in the card accommodation space without the back surface of the second card 51b coming into contact with the upper surface of the bottom wall portion 11a, the second card The upper end edge of the leading end of 51b in contact with the gate part 22 inclined obliquely downward presses the gate part 22 upward. However, since the first stopper protrusion 26a and the second stopper protrusion 26b of the changer 21 remain in the initial state and the stopper has not been released, the first stopper protrusion 26a and the second stopper protrusion 26a and the second stopper protrusion 26a are moved upward. 2 The lower surface of the stopper projection 26b is in contact with the upper surfaces of the card back surface first guide portion 11m and the card back surface second guide portion 11n and cannot move downward any more, and the gate portion 22 cannot move upward. ing. Therefore, when the second card 51b is further moved toward the rear wall portion 11b of the card connector 10, the second card 51b in which the upper end edge at the front end in the insertion direction is in contact with the gate portion 22 inclined obliquely downward is: It is moved downward along the back surface of the gate portion 22 and reaches a position as shown in FIG. That is, the second card 51b is guided by the gate portion 22 so as to move obliquely downward.

  Subsequently, when the second card 51b is further moved toward the rear wall portion 11b of the card connector 10, the pressure receiving portion 32 of the inner shell 31 is positioned higher than the upper surface of the second card 51b. Enters below the pressure receiving portion 32. Here, since the gap between the front end edge of the pressure receiving portion 32 and the rear end edge of the gate portion 22 is extremely narrow, the second card 51b is guided to move obliquely downward by the gate portion 22. Even so, it is possible to smoothly enter the pressure receiving portion 32 below. Further, when the second card 51b passes below the pressure receiving portion 32, the upper surface of the second card 51b is guided in contact with the back surface of the pressure receiving portion 32, so that the pressure receiving portion 32 moves upward from the second card 51b. It may receive a pressing force. However, since the upward movement of the inner shell 31 is restricted by the shell 12 attached to the housing 11, the inner shell 31 does not move upward from the position in the initial state.

  Subsequently, when the second card 51b is further moved toward the rear wall portion 11b of the card connector 10, the lower portion of the front surface of the left corner portion at the front end in the insertion direction of the second card 51b and the rear surface of the left corner portion. The surface on the back side of the formed recess is in contact with the second butting portion 42f and the third butting portion 42h of the cam slider 41, and is formed at the left end near the leading end in the insertion direction on the back surface of the second card 51b. The combined recess engages with the second locking action portion 43 e of the cam slider 41. As a result, the second card 51 b is temporarily held by the cam slider 41 and moves together with the cam slider 41. In this case, the second card erroneous insertion prevention protrusion 11s is disposed at a position immediately before the second contact portion 15b of the bottom wall portion 11a, but is inclined rearward and downward at the distal end in the insertion direction of the second card 51b. Since the second chamfered portion 52b is in contact with the second card erroneous insertion preventing projection 11s, the second card 51b can smoothly ride on the second card erroneous insertion preventing projection 11s. Can move without receiving resistance.

  Subsequently, when the second card 51b is further moved toward the rear wall portion 11b of the card connector 10, the cam slider 41 moves together with the second card 51b, reaches the terminal point that is the most advanced position, and reaches the full position. Stroke state.

  Subsequently, when the force to move the second card 51b toward the rear wall portion 11b of the card connector 10 is released, the cam slider 41 and the second card 51b receive the repulsive force of the urging member 45 and receive the rear wall. It is moved toward the direction away from the portion 11b, that is, toward the insertion opening of the card connector 10. Then, the cam slider 41 and the second card 51b are stopped at a lock position where the second card 51b is held in the card connector 10 while being locked. Thus, the second card 51b is loaded at a predetermined position in the card connector 10 as shown in FIG. Further, since the cam slider 41 is at the lock position, the card 51 is locked by the cam slider 41 and is prevented from moving in the front-rear direction.

  In a state where the second card 51b is loaded in the card connector 10, the second contact portion 15b of the terminal 15 contacts the card side connection terminal disposed on the back surface near the front end in the insertion direction of the second card 51b. Are electrically connected. In this case, the second contact portion 15b itself functions as a cantilever having elasticity, and is elastically pressed against the card side connection terminal of the second card 51b. Note that the pressure at which the second contact portion 15b comes into contact with the card side connection terminal, that is, the contact pressure is received by the pressure receiving portion 32 with which the upper surface of the second card 51b is in contact, so the second contact portion 15b and the card Contact can be reliably maintained with the side connection terminals.

  Note that the distance from the front end of the card connector 10 to the rear end in the insertion direction of the second card 51b when the second card 51b is in the locked position, that is, from the insertion opening of the card connector 10 of the second card 51b. The protruding amount is equal to the protruding amount from the insertion opening of the card connector 10 of the first card 51a in a state where the first card 51a is in the locked position. In other words, when inserted into the card connector 10, the leading end of the first card 51a having a large outer dimension reaches the depth of the card housing space, and the leading end of the second card 51b having a small outer dimension is inserted. The card does not reach the back of the card accommodation space and stops at a position close to the front.

  As described above, when the second card 51b is inserted into the card housing space of the card connector 10, the changer 21 swings by identifying that the inserted card 51 is the second card 51b having a small outer dimension. First, the second card 51b is distributed to the lower side in the card accommodation space, and is passed through the lower passage of the inner shell 31. In this case, the inner shell 31 serves as a top plate of the lower passage, demarcates the passage of the second card 51b, receives the contact pressure of the second contact portion 15b, and connects the second contact portion 15b and the card side. Maintain contact with the terminals.

  Further, when taking out the second card 51b loaded in the card connector 10, the second card 51b is moved toward the rear wall portion 11b of the card connector 10. The cam slider 41 moves together with the second card 51b, reaches the terminal point that is the most advanced position, and enters a full stroke state.

  Subsequently, when the force to move the second card 51b toward the rear wall portion 11b of the card connector 10 is released, the cam slider 41 and the second card 51b receive the repulsive force of the urging member 45, and the card The connector 10 is moved toward the insertion opening of the connector 10. Then, the cam slider 41 stops when it returns to the initial position shown in FIGS. In this case, since the second card 51b is temporarily held by the cam slider 41, the second card 51b stops together with the cam slider 41 and does not fly out of the card connector 10 due to inertia. Since the second card 51b is only temporarily held, it is not necessary to apply force when the user pulls it out toward the insertion opening with fingers or the like, and can be easily taken out from the card connector 10.

  In this case, as the second card 51b moves toward the insertion opening, the changer 21 and the inner shell 31 perform an operation reverse to the case where the first card 51a is inserted, and maintain the initial position. Note that when the user forcibly pulls out the second card 51b locked by the cam slider 41 loaded in the card connector 10 from the card connector 10 with a force stronger than usual, that is, the first card Even when the second card 51b is forcibly removed, the changer 21 and the inner shell 31 operate in the reverse manner to the case where the second card 51b is inserted as the second card 51b moves toward the insertion opening. To maintain the initial position.

  Next, the operation when the second card 51b is inserted in the front or back direction or the front-back direction, that is, when it is erroneously inserted will be described. In addition, description is abbreviate | omitted about the operation | movement same as the operation | movement in the case of inserting the 2nd card | curd 51b in the suitable direction mentioned above.

  Even when the second card 51b is moved toward the rear wall portion 11b of the card connector 10 even when inserted in the front-back or front-back direction, the second card 51b passes below the gate portion 22 and receives the pressure receiving portion. 32 can be entered below. However, when the second card 51b is further moved toward the rear wall portion 11b of the card connector 10, a surface other than the second chamfered portion 52b, that is, a vertical surface extending in the vertical direction is the bottom wall portion 11a. Will come into contact with the second card erroneous insertion preventing protrusion 11s disposed at a position immediately before the second contact portion 15b. Therefore, the second card 51b is prevented from moving forward by the second card erroneous insertion preventing projection 11s and cannot move further toward the rear wall portion 11b, and the second contact portion 15b is damaged. There is no. In this manner, the second card erroneous insertion preventing protrusion 11s functions as an erroneous insertion preventing member, thereby preventing erroneous insertion of the second card 51b.

  However, for some reason, the second card 51b can ride on the second card erroneous insertion prevention protrusion 11s and may move further. However, in this case, the third contact portion 42h of the cam slider 41 prevents the second card 51b from moving forward, so that the second contact portion 15b is not damaged. In this way, the third abutting portion 42h functions as a second card erroneous insertion preventing portion, and erroneous insertion of the second card 51b is prevented. The third abutting portion 42h is face-to-face or reverse in the front-rear direction with the rear end of the cam slider 41 abutting against the rear wall portion 11b of the housing 11 so that the cam slider 41 cannot move further rearward. The function of preventing the inserted second card 51b from moving forward is sufficiently exhibited.

  As described above, the second card erroneous insertion preventing protrusion 11s and the third abutting portion 42h of the cam slider 41 perform the function of preventing the erroneous insertion, so that the erroneously inserted second card 51b is reliably advanced. Can be prevented.

  As described above, in the present embodiment, in the housing 11 of the card connector 10, the first card 51a is inserted in the front or back direction or the front-rear reverse direction at a position closer to the insertion opening than the first contact portion 15a as the first connection terminal. The second card 51b is inserted in the front or back direction or in the front-rear reverse direction at a position closer to the insertion opening than the second contact portion 15b serving as the second connection terminal and the first card misinsertion prevention protrusion 11r. The card guide mechanism of the card connector 10 includes a first abutting portion 42b that engages with the first card 51a, including a bottom wall portion 11a having a second card erroneous insertion preventing projection 11s that prevents the second card from being inserted. In addition, a second abutting portion 42f and a third abutting portion 42h that engage with the second card 51b at a position closer to the insertion opening than the first abutting portion 42b are provided. Than the first engagement portion 42d for preventing the insertion of the first card 51a at the position closer to the insertion opening than the first engagement portion, or the first card erroneous insertion prevention portion 42d for preventing the first card 51a from being inserted in the reverse direction. A third abutting portion 42h for preventing the second card 51b from being inserted in the front or back direction or the front-rear reverse direction at a position near the insertion opening is provided, and a slider member 42 that slides in the insertion direction and the direction opposite to the insertion direction is provided. Contains.

  The first card misinsertion preventing projection 11r and the second card misinsertion preventing projection 11s are respectively inserted at the leading ends of the first card 51a and the second card 51b inserted in the reverse direction. Abut.

  Further, the first card misinsertion preventing portion 42d and the second card misinsertion preventing portion abut on the leading ends of the first card 51a and the second card 51b inserted in the front-back or front-reverse direction, respectively. When the slider member 42 moves in the insertion direction and stops at the end point, the first card 51a and the second card 51b are stopped.

  Further, the card connector 10 is swingably attached to the housing 11 at a position closer to the insertion opening than the second contact portion 15b. The card connector 10 identifies the first card 51a and the second card 51b, and sets each to the upper side. A changer 21 that distributes to the lower side, a bottom plate of the passage of the first card 51a, and a passage of the second card 51b, which are attached to the housing 11 so as to be vertically movable at a position closer to the insertion opening than the changer 21 of the housing 11. And an inner shell 31 that prevents the first card 51a from being inserted in the front or back direction or in the front-rear reverse direction.

  Furthermore, the inner shell 31 is urged upward in the initial state, and the edge on the insertion opening side comes into contact with the front end of the first card 51a inserted in the reverse direction.

  Therefore, it is possible to reliably prevent the first card 51a and the second card 51b from being erroneously inserted, and the components inside the card connector 10 such as the first contact portion 15a and the second contact portion 15b are damaged. There is no. In particular, in the case of the first card 51a, the first card 51a inserted in the front-back or front-reverse direction first comes into contact with the inner shell 31, so that erroneous insertion is reliably prevented. Thereby, the 1st card | curd 51a and the 2nd card | curd 51b can be loaded easily and appropriately.

  In the present embodiment, for convenience of explanation, the first card 51a and the second card 51b have been described as being a memory stick (R) and a memory stick Duo (R), respectively. Those skilled in the art can easily understand that 51a and the second card 51b may be other types of cards. For example, even when the first card 51a and the second card 51b are an SD (R) card and a miniSD (R) card, respectively, the shape, size, arrangement, and the like of each member described in the present embodiment are adjusted. Thus, the present invention can be applied without changing the essence.
