Description

  The present invention relates to a card connector, and more particularly to a card connector for a SIM (Subscriber Identity Module) card.

  Conventionally, as a card connector for a SIM card, a push-push type card connector is known (for example, see Patent Document 1). The card connector described in Patent Document 1 is provided with a lock mechanism that locks a slide member that slides with the SIM card in the insertion direction and the ejection direction in the housing at the mounting position. The lock mechanism locks the slide member at the mounting position by pushing in the SIM card, and unlocks the slide member by further pushing in the SIM card. When the slide member is unlocked, the SIM card is pushed back to the discharge position via the slide member by the biasing force of the discharge spring that biases the slide member in the discharge direction.

  By the way, a holding notch for preventing the SIM card from coming off from the slide member is not formed on the side surface of the SIM card. Therefore, even if the slide member is locked at the mounting position, the SIM card may come out of the connector due to vibration or the like. For this reason, a configuration in which a retaining member for retaining is provided on the mounting port side of the card connector is conceivable (see, for example, Patent Document 2). The retaining member of the card connector described in Patent Document 2 is manually moved between a retaining position where a part of the mounting opening is blocked and a retracted position where the retaining member is retracted from the retaining position. The SIM card is prevented from being detached from the connector by the movement of the retaining member to the retaining position, and can be inserted into and removed from the connector by the movement of the retaining member to the retracted position.

JP 2003-17183 A Japanese Patent No. 2717349

  However, in the conventional card connector described above, since the retaining member is manually operated, there is a possibility that the operation of the retaining member may be forgotten when the SIM card is mounted, and the SIM card cannot be reliably prevented from being detached. there were. Further, when the SIM card is inserted, the retaining member is manually operated after the SIM card is inserted to prevent the retaining member. When the SIM card is ejected, the retaining member is manually operated to release the retaining member, and then the SIM card is taken out. There is a problem that the operation becomes complicated because it is necessary.

  The present invention has been made in view of such a situation, and even if a card that does not have a notch for holding to prevent detachment from the slide member is used, the card does not require a complicated operation. An object of the present invention is to provide a card connector that can reliably prevent a card from being detached when the card is mounted.

  The card connector of the present invention is formed so as to be slidable in the housing together with the card in the card insertion space and the card insertion space and in the card ejection direction, and is mounted by pushing the card into the card mounting space. A slide member that is held in position and returned to the ejection position by further pushing from the mounting position, and a holding portion that holds the card to prevent it from being removed from the retaining position that prevents the card from being removed, and the retaining position. A retaining member that moves between a retracted position and a retracted position, wherein the retaining member is interlocked with a slide of the slide member via a connecting portion provided on the slide member, and the mounting of the slide member The holding portion is moved to the retaining position by sliding to the position, and the slide member is moved to the discharging position. Wherein is brought into contact with the card in the holding section by id, characterized by moving the holding portion in the retracted position.

  According to this configuration, the retaining portion of the retaining member is moved to the retaining position in conjunction with the sliding of the sliding member to the mounting position. Therefore, when the card is mounted, even if the forgetting operation of the retaining member is forgotten, the retaining portion is moved to the retaining position, so that the retaining portion can reliably prevent the card from being removed from the card connector. Further, when the slide member slides to the discharge position, the holding portion is brought into contact with the card and moved to the retracted position. Therefore, when the card is ejected, the holding portion is moved to the retracted position without operating the retaining member, so that the card ejection is not hindered by the holding portion. Further, since manual operation of the retaining member is not required, the card mounting operation and the ejecting operation can be easily performed. Further, since the holding portion of the retaining member is moved to the retracted position by the contact of the card moved in the ejection direction, the card can be smoothly ejected, and the operability can be improved. Furthermore, when the card is ejected, the card is braked by contact with the holding portion, so that the card can be prevented from unexpectedly popping out.

  In the card connector according to the present invention, the connecting portion may include a first restricting portion that restricts movement of the holding portion to the retaining position when the slide member is in the discharge position. It is characterized by.

  According to this configuration, since the holding portion is not moved to the retaining position when the card whose slide member is at the ejection position is not mounted, the card mounting on the card connector is not hindered.

  In the card connector according to the present invention, the connecting portion may include a second restricting portion that restricts movement of the holding portion to the retracted position when the slide member is in the mounting position. Features.

  According to this configuration, since the holding portion is not moved to the retracted position when the card having the slide member in the mounting position is mounted, the card can be prevented from being forcibly removed from the card connector.

  In the card connector, the present invention further includes a stopper for restricting movement of the slide member in the discharge direction, and the connecting portion extends from the slide member in the discharge direction so as to bypass the stopper. The retaining member is interlocked with the slide of the slide member in the vicinity of the card slot.

  According to this configuration, the stopper does not restrict the interlocking between the slide member and the retaining member in the vicinity of the mounting opening.

  According to the present invention, in the card connector, a cam mechanism is formed by a cam driven surface formed on the retaining member and a cam portion formed on the connecting portion and contacting the cam driven surface. The stop member is characterized in that the slide in the insertion direction of the slide member is converted by the cam mechanism, and the holding portion is moved to the retaining position.

  According to this configuration, the slide in the insertion direction of the slide member and the movement of the holding portion to the retaining position can be linked with a simple configuration.

  According to the present invention, in the card connector, the retaining member is swingably supported on the housing, and the slide of the slide member is converted by the cam mechanism to swing the holding portion. It is characterized by that.

  According to this configuration, by swinging the retaining member, it is possible to make a large portion of the holding portion that can contact the card without increasing the width of the card connector.

  According to the present invention, in the card connector, a delay mechanism for delaying movement of the holding portion to the retaining position is formed by the retaining member and the connecting portion with respect to the slide of the slide member to the mounting position. It is characterized by that.

  According to this configuration, even when a long card is inserted in the insertion direction, by delaying the movement of the holding portion to the retaining position, the collision between the holding portion and the card being inserted is prevented, The card can be installed smoothly.

  In the card connector according to the present invention, the delay mechanism includes a spring portion provided in the retaining member and a contact portion provided in the connecting portion and capable of contacting the spring portion. And while the slide member is slid by a predetermined length in the insertion direction from the discharge position, the holding portion is biased toward the retracted position side by the spring portion that is in contact with the contact portion. The movement of the holding portion to the retaining position is delayed.

  According to this configuration, the movement timing of the holding portion can be delayed by the contact between the spring portion and the contact portion, and the delay mechanism can be configured with a simple configuration.

  According to the present invention, even when a card that does not have a notch for holding to prevent detachment from the slide member is used, the card can be reliably prevented from being detached when the card is loaded without requiring a complicated operation. can do.

  Hereinafter, a first embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following, a case where the present invention is applied to a card connector to which a SIM card is attached will be described. However, the application target of the card connector according to the present embodiment is not limited to this and can be appropriately changed.

  First, before explaining the card connector according to the present embodiment, a card to be mounted will be explained. FIG. 13 is a plan view of the card according to the first embodiment of the present invention, in which (a) shows a top view and (b) shows a rear view.

  As shown in FIGS. 13A and 13B, the card 81 is a so-called SIM card, which is a storage medium formed in a substantially rectangular shape when viewed from above and having an information storage unit. At one corner of the card 81, an inclined surface 82 that is notched and inclined at about 45 degrees is formed. The inclined surface 82 is used to identify the insertion direction of the card 81, and the side on which the inclined surface 82 is formed is the front end side in the insertion direction, and the opposite side is the rear end side in the insertion direction.

  On the back surface of the card 81, a plurality of contact pads 83 for reading or writing information in contact with the plurality of contact terminals 15 of the card connector 1 in a substantially half portion on the rear end side in the insertion direction of the card 81. Is provided. Further, the side surface of the card 81 is formed flat along the insertion direction and is in surface contact with the side surface of the slide member 6 of the card connector 1. That is, the card 81 is not held by the slide member 6 of the card connector 1 and is operated in the insertion direction and the ejection direction while being in surface contact with the slide member 6.

  Next, the overall configuration of the card connector will be described with reference to FIGS. FIG. 1 is a perspective view of a card connector according to a first embodiment of the present invention. FIG. 2 is a perspective view of the card connector with the cover removed according to the first embodiment of the present invention.

  As shown in FIGS. 1 and 2, the card connector 1 according to the present embodiment is mounted in a connector main body 2 having an upper surface and a front surface opened, and an opening in the upper surface of the connector main body 2. The connector body 2 and the cover 3 are combined to form a box-like body having the mounting opening 4. A plurality of contact terminals 15 are provided in a substantially front half portion of the bottom wall portion 11 of the connector main body 2 on the mounting opening 4 side. Each contact terminal 15 extends from the substantially front half portion of the bottom wall portion 11 toward the back wall portion 12 side.

  On the back wall portion 12 of the connector main body 2, a switch portion 5 for detecting attachment of the card 81 is provided. The switch unit 5 includes a lever 21 that is swingably supported on the back wall 12 and a contact spring 22 provided on the lever 21. The switch unit 5 is opposed to the pair of fixed contacts 23 and 24 exposed on the inner surface of the back wall 12, and contacts one end of the contact spring 22 with the one fixed contact 23 when the card 81 is not attached. The other end of the spring 22 is separated from the other fixed contact 24. Then, when the switch unit 5 is pushed into the back wall 12 side by the card 81, the other end of the contact spring 22 is brought into contact with the other fixed contact 24 by the rotation of the lever 21 to detect the mounting of the card 81. .

  A slide member 6 that can slide along the side wall 13 and a coil-shaped discharge spring 7 that expands and contracts as the slide member 6 slides are provided on the side wall 13 side of the connector body 2. The discharge spring 7 has one end in contact with the back wall portion 12 and the other end in contact with the slide member 6, and biases the slide member 6 in the discharge direction. Further, a stopper 26 is provided on the mounting opening 4 side of the connector main body 2 so as to block the slide of the slide member 6 in the discharge direction. The stopper 26 abuts on the slide member 6 to restrict the slide member 6 to the discharge position.

  The slide member 6 is configured to be slidable in the insertion direction and the discharge direction while being urged by the discharge spring 7. The slide member 6 has an arm portion 31 extending from the front end side in the insertion direction toward the center of the connector main body 2. The arm portion 31 abuts on the front end surface in the insertion direction of the card 81 and causes the slide member 6 and the card 81 to operate integrally.

  A heart cam groove 39 is formed on the upper surface of the slide member 6, and the position of the slide member 6 is defined by the heart cam groove 39 and the latch pin 8 provided on the stopper 26. The latch pin 8 extends in the sliding direction of the slide member 6, and both ends are bent at a substantially right angle toward the bottom wall portion 11. One end of the latch pin 8 is rotatably supported by the stopper 26, and the other end is slid on the heart cam groove 39 of the slide member 6.

  The heart cam groove 39 is formed in a heart-shaped annular shape having a plurality of steps and slopes, and slides the other end of the latch pin 8 in one direction in accordance with the slide of the slide member 6. When the slide member 6 is pushed into the mounting position in the vicinity of the back wall portion 12, the other end of the latch pin 8 is locked to the locking portion of the heart cam groove 39, and the return of the slide member 6 due to the bias of the discharge spring 7 is restricted. The When the slide member 6 is further pushed from this state, the latched state between the latch pin 8 and the heart cam groove 39 is released, and the slide member 6 is returned by the biasing force of the discharge spring 7. Thus, the latch pin 8 and the heart cam groove 39 have a holding function at the mounting position of the slide member 6.

  Further, the slide member 6 is provided with a connecting portion 32 that passes through the side of the stopper 26 and extends to the mounting port 4 side. In the vicinity of the distal end of the connecting portion 32, a retaining member 9 that interlocks with the slide member 6 is provided. The retaining member 9 has a holding piece 44 that retains and holds the card 81. Further, the retaining member 9 is linked to the slide member 6 via the connecting portion 32 and moves the holding piece 44 between a retaining position that closes a part of the mounting opening 4 and a retracted position that is retracted from the retaining position. Let

  The cover 3 is formed by bending a metal plate, and a pin presser 35 for pressing the latch pin 8 is formed on one side of the upper plate. The pin presser 35 is a cantilever spring cut and raised toward the bottom wall 11, and presses the middle part of the latch pin 8 downward to press the other end of the latch pin 8 against the heart cam groove 39.

  Hereinafter, with reference to FIG.3 and FIG.4, the interlocking | linkage structure of a slide member and a retaining member is demonstrated. FIG. 3 is an explanatory diagram of an interlocking configuration of the slide member and the retaining member according to the first embodiment of the present invention. FIG. 4 is an explanatory view of the swinging state of the retaining member when a card having a dimensional error according to the first embodiment of the present invention is mounted. FIG. 3 shows the interlocking state between the slide member and the retaining member when the card is ejected.

  As shown in FIG. 3, the connecting portion 32 extends toward the mounting opening 4 so as to bypass the stopper 26, and is formed so as to be able to contact the retaining member 9. For this reason, the slide member 6 and the retaining member 9 are not restricted from being interlocked by the stopper 26 in the vicinity of the mounting opening 4. An inclined surface 33 capable of transmitting the slide of the slide member 6 to the spring piece 43 of the retaining member 9 is formed at the distal end portion of the connecting portion 32. The inclined surface 33 is inclined so as to narrow the interval with the side wall portion 13 toward the mounting opening 4 side. The inclined surface 33 presses the spring piece 43 of the retaining member 9 by moving with the slide of the slide member 6.

  The retaining member 9 is formed by bending a metal plate, and has a flat plate portion 42 that is swingably supported by a support protrusion 41 provided on the bottom wall portion 11 of the connector main body 2. A cantilever spring piece 43 is provided on the back wall 12 side of the flat plate part 42. The spring piece 43 extends from the base end portion connected to the flat plate portion 42 toward the stopper 26, and is folded back to the base end portion in the middle of the extending direction. When the free end side of the spring piece 43 is pressed against the inclined surface 33 of the connecting portion 32, the retaining member 9 is swung around the support protrusion 41.

  A holding piece 44 that holds and holds the card 81 is provided on the mounting opening 4 side of the flat plate portion 42. The holding piece 44 extends from the base end portion connected to the flat plate portion 42 toward the mounting opening 4 side (card 81 side) and is bent toward the base end side in the middle portion. The holding piece 44 holds and holds the card 81 at a substantially half portion on the base end side. A substantially half portion on the front end side of the holding piece 44 is bent so as to avoid contact with the card 81 at the retracted position.

  Further, the vicinity of the spring piece 43 of the flat plate portion 42 is a regulating piece 45 that regulates the swing range of the retaining member 9 together with the first and second regulating portions 48 and 49 provided in the connecting portion 32. . The restricting piece 45 is positioned at the step portion 47 that is one step lower than the first and second restricting portions 48 and 49 in the connecting portion 32. The retaining member 9 is restricted from swinging in the retaining direction by the restricting piece 45 and the first restricting portion 48 when the slide member 6 is in the discharge position. Thereby, the holding piece 44 is not moved to the retaining position when the card 81 is not mounted, and the mounting of the card 81 is not hindered. Further, when the slide member 6 is in the mounting position, the retaining member 9 is restricted from swinging in the retracting direction by the restriction piece 45 and the second restriction portion 49. Thereby, the holding piece 44 is not moved to the retracted position when the card 81 is mounted, and the card 81 is reliably prevented from being detached.

  In this case, the retaining member 9 absorbs a dimensional error in the insertion direction of the card 81 by the spring piece 43. For example, as shown in FIG. 4, when a card 81 having a large dimension in the insertion direction is attached to the card connector 1, the spring piece 43 is greatly bent and the swinging amount of the retaining member 9 is adjusted and held. It is possible to prevent the card 81 from being detached by the piece 44. In this way, the amount of rocking of the retaining member 9 is adjusted by the bending of the spring piece 43. Further, even when external vibration or the like is applied to the card connector 1, vibration generated between the retaining member 9 and the slide member 6 is absorbed by the spring piece 43, so that the generation of abnormal noise can be prevented and the operation can be prevented. It becomes possible to improve the property.

  Here, with reference to FIG. 5, the swinging operation of the retaining member will be described. FIG. 5 is a transition diagram of the swinging motion of the retaining member according to the first embodiment of the present invention. 5, (a) to (c) show the swinging motion of the retaining member when the card is mounted, and (c) to (e) show the swinging motion of the retaining member when the card is ejected. ing.

  As shown in FIG. 5A, when the slide member 6 is at the ejection position, the card 81 is pushed out of the mounting opening 4 by the slide member 6. At this time, the retaining member 9 has the holding piece 44 positioned at the retracted position, and swinging in the retaining direction is restricted by the restricting piece 45 and the first restricting portion 48. When the card 81 is pushed from this state, the slide member 6 is slid in the insertion direction, and the spring piece 43 of the retaining member 9 and the inclined surface 33 of the connecting portion 32 are brought into contact with each other.

  As shown in FIG. 5B, when the card 81 is further pushed in and the slide member 6 is further slid in the insertion direction, the spring piece 43 starts to ride on the inclined surface 33. The retaining member 9 starts swinging in the retaining direction around the support protrusion 41 by pushing the inclined surface 33 against the spring piece 43. At this time, the retaining member 9 is not restricted from swinging because the restricting piece 45 and the first restricting portion 48 are separated from each other.

  As shown in FIG. 5C, when the card 81 is mounted on the card connector 1 and the slide member 6 is slid to the mounting position, the spring piece 43 rides completely on the inclined surface 33. The retaining member 9 moves the holding piece 44 to the retaining position by swinging in the retaining direction. As a result, the holding piece 44 of the retaining member 9 protrudes toward the mounting opening 4, and the card 81 is prevented from being detached from the card connector 1. At this time, the retaining member 9 is restricted from swinging in the retracting direction by the restriction piece 45 and the second restriction portion 49. Therefore, forcible removal of the card 81 from the card connector 1 is prevented.

  In this manner, the holding piece 44 of the retaining member 9 is moved to the retaining position in conjunction with the sliding of the sliding member 6 to the mounting position. Therefore, the card 81 is prevented from being detached by the retaining member 9 during the mounting operation, so that it is possible to reliably prevent the card 81 from being detached from the card connector 1.

  When the card 81 is further pushed in from the state shown in FIG. 5C, the slide member 6 is pushed back together with the card 81 in the ejecting direction, and the second regulating portion 49 restricts the swinging of the retaining member 9 in the retracting direction. Canceled.

  As shown in FIG. 5D, when the slide member 6 is slid in the ejection direction, the holding piece 44 of the retaining member 9 is pushed in by the rear end of the card 81. The retaining member 9 starts swinging in the retracting direction around the support protrusion 41 by pushing the card 81 against the holding piece 44. At this time, since the spring piece 43 goes down the inclined surface 33, the amount of pushing of the inclined surface 33 with respect to the spring piece 43 is reduced, and the resistance of the spring piece 43 to the swinging of the retaining member 9 in the retracting direction is weakened.

  As shown in FIG. 5E, when the card 81 is ejected from the card connector 1 and the slide member 6 is slid to the ejection position, the retaining member 9 retracts the holding piece 44 by swinging in the retracting direction. Move to position. Thereby, the holding piece 44 of the retaining member 9 is retracted from the mounting opening 4 side, and the card 81 can be inserted into and removed from the card connector 1. At this time, the retaining member 9 is restricted from swinging in the retaining direction by the restricting piece 45 and the first restricting portion 48 of the connecting portion 32.

  In this way, the holding piece 44 of the retaining member 9 is moved to the retracted position in conjunction with the slide of the slide member 6 to the discharge position. Accordingly, since the retaining member 9 is released by the card 81 ejection operation, the ejection of the card 81 from the card connector 1 is not restricted.

  With reference to FIG.6 and FIG.7, the mounting operation | movement and discharge operation | movement of a card | curd connector are demonstrated. FIG. 6 is an explanatory diagram of a card mounting operation by the card connector according to the first embodiment of the present invention. FIG. 7 is an explanatory diagram of a card ejection operation by the card connector according to the first embodiment of the present invention. 6 and 7, the cover is omitted for convenience of explanation.

  First, the mounting operation of the card 81 by the card connector 1 will be described. As shown in FIG. 6A, when the card 81 is inserted into the card connector 1, the tip of the card 81 is brought into contact with the arm portion 31 of the slide member 6. At this time, since the retaining member 9 is restricted from swinging in the retaining direction by the first restricting portion 48, the retaining member 9 does not prevent the card 81 from being inserted. When the card 81 is pushed from this state, the slide member 6 slides toward the mounting position, and the swing restriction of the retaining member 9 in the retaining direction is released.

  As shown in FIG. 6B, when the card 81 is further pushed in, the slide member 6 is further slid to the mounting position side while the heart cam groove 39 slides on the other end of the latch pin 8. As the slide member 6 slides in the insertion direction, the spring piece 43 of the retaining member 9 is pushed into the inclined surface 33 of the connecting portion 32, and the retaining member 9 swings around the support protrusion 41 in the retaining direction. Is done.

  As shown in FIG. 6C, when the card 81 is further pushed in, the other end of the latch pin 8 is locked to the locking portion of the heart cam groove 39, and the card 81 is held in the mounting position together with the slide member 6. Then, the holding piece 44 of the retaining member 9 is moved to the retaining position, and the card 81 is prevented from being detached from the card connector 1. Further, the switch unit 5 is pushed in by the card 81, and attachment of the card 81 is detected. The contact pad 83 of the card 81 comes into contact with the contact terminal 15 of the card connector 1 by being held in the mounting position, and signals can be exchanged between the information storage unit of the card 81 and the host device. Become.

  Next, the discharging operation of the card 81 by the card connector 1 will be described. As shown in FIG. 7A, in the mounted state of the card 81, the other end of the latch pin 8 is locked to the locking portion of the heart cam groove 39, and the sliding of the slide member 6 in the discharge direction is restricted. . At this time, the retaining member 9 is prevented from forcibly removing the card 81 because the second restricting portion 49 restricts swinging in the retracting direction.

  As shown in FIG. 7B, when the card 81 is further pushed, the latched state between the latch pin 8 and the heart cam groove 39 is released, and the slide member 6 is pushed back toward the discharge position by the discharge spring 7. As the slide member 6 slides in the ejecting direction, the holding piece 44 of the retaining member 9 is pushed out to the rear end of the card 81, and the retaining member 9 is swung in the retracting direction around the support protrusion 41.

  As shown in FIG. 7C, when the slide member 6 is slid to the discharge position, the holding piece 44 of the retaining member 9 is moved to the retreat position by the pushing out by the card 81. In this way, the card 81 is ejected from the mounting port 4 of the card connector 1. Further, since the pushing of the card 81 into the switch unit 5 is released, the ejection of the card 81 is detected. Then, when the card 81 is moved from the mounting position to the ejection position, the contact pad 83 of the card 81 is separated from the contact terminal 15 of the card connector 1.

  As described above, according to the card connector 1 according to the present embodiment, the retaining member 9 is pushed by being pushed into the inclined surface 33 of the connecting portion 32 in conjunction with the slide of the slide member 6 to the mounting position. The holding piece 44 is moved to the retaining position. Therefore, the card 81 is prevented from being detached by the retaining member 9 during the mounting operation, so that it is possible to reliably prevent the card 81 from being detached from the card connector 1. Further, in conjunction with the slide of the slide member 6 to the discharge position, the holding piece 44 is moved to the retracted position by being pressed by the card 81. Accordingly, since the retaining member 9 is released from the retaining operation by the ejection operation of the card 81, the ejection of the card 81 from the card connector 1 is not hindered. Further, since manual operation with respect to the retaining member 9 is not required, the card 81 can be easily mounted and ejected. Further, since the holding piece 44 is moved to the retracted position by the contact of the card 81 moved in the discharging direction, the card 81 can be discharged smoothly, and the operability can be improved. Furthermore, since the card 81 is braked by the contact with the holding piece 44 when the card 81 is ejected, the card 81 can be prevented from unexpectedly popping out.

  Next, a second embodiment of the present invention will be described. The card connector according to the second embodiment of the present invention is different only in the interlocking configuration of the card connector, slide member, and retaining member according to the first embodiment described above. Therefore, only the differences will be particularly described. FIG. 8 is a perspective view of the card connector with the cover removed according to the second embodiment of the present invention. FIG. 9 is a plan view of a slide member and a retaining member according to the second embodiment of the present invention. FIG. 10 is an explanatory diagram of the interlocking configuration of the slide member and the retaining member according to the second embodiment of the present invention.

  As shown in FIG. 8, the card connector 51 has the same configuration as the card connector shown in the first embodiment, except for the slide member 55 and the retaining member 56. The slide member 55 is slidably disposed along one side wall portion 58 of the connector main body 52, and is urged in the discharge direction by a discharge spring (not shown). In addition, a stopper 61 that restricts sliding of the slide member 55 is provided in front of the slide member 55 in the discharging direction. In the vicinity of the stopper 61, a retaining member 56 for retaining the card 81 is provided in conjunction with the slide member 55.

  As shown in FIG. 9, the slide member 55 is provided with a connecting portion 62 that extends toward the mounting opening, and the connecting portion 62 has an opening 63 that can accommodate the stopper 61. For this reason, the slide member 55 and the retaining member 56 are not regulated by the stopper 61 in the vicinity of the mounting opening. Further, since the stopper 61 is disposed in the opening 63, the card connector 51 can be made thinner than the configuration in which the connecting portion 62 is bypassed so as to pass over the stopper 61.

  A cam portion 64 that protrudes toward the bottom wall portion 59 is formed at the distal end portion of the connecting portion 62. The cam portion 64 is formed with a space that can accommodate the lever 66 of the retaining member 56 between the cam portion 64 and the side wall portion 58. The cam portion 64 drives the retaining member 56 by slidingly contacting the side surface 65 of the lever 66 as the slide member 55 slides. That is, a cam mechanism is formed by the cam portion 64 and the side surface 65 of the lever 66 that functions as a cam driven surface.

  The retaining member 56 includes a lever 66 having a substantially arc shape when viewed from above, and a holding portion 67 provided on the distal end side of the lever 66. On the back surface of the lever 66, a swinging protrusion 68 protrudes toward the bottom wall 59. The retaining member 56 is swingably supported by the bottom wall portion 59 by inserting the swing protrusion 68 into a support hole provided in the bottom wall portion 59 of the connector main body 52. The side surface 65 of the lever 66 extends in a substantially arc shape, and is a sliding contact surface that is in sliding contact with the cam portion 64. When the arc-shaped side surface 65 of the lever 66 is pressed by the cam portion 64, the retaining member 56 is swung around the support hole.

  As shown in FIG. 10A, when the slide member 55 is in the discharge position, the cam portion 64 is in contact with one end side of the lever 66 on the holding portion 67 side, and the holding portion 67 is located in the retracted position. . When the card 81 is pushed from this state, the slide member 55 is slid in the insertion direction, and the cam portion 64 slides on the side surface 65 of the lever 66 from one end side to the other end side. Then, when the cam portion 64 is in sliding contact with the other end of the side surface 65 of the lever 66, the retaining member 56 is swung in the retaining direction around the support hole.

  As shown in FIG. 10B, when the card 81 is further pushed in and the slide member 55 is slid to the mounting position, the holding portion 67 of the retaining member 56 is moved to the retaining position. As a result, the holding portion 67 protrudes toward the mounting opening side, and the card 81 is prevented from being detached from the card connector 51. Further, the other end of the latch pin 57 is locked to the locking portion of the heart cam groove 69, and the card 81 is held in the mounting position together with the slide member 55.

  Thus, in conjunction with the slide of the slide member 55 to the mounting position, the holding portion 67 of the retaining member 56 is moved to the retaining position. Therefore, the card 81 is prevented from being detached by the retaining member 56 in the mounting operation of the card 81, so that it is possible to reliably prevent the card 81 from being detached from the card connector 51.

  As shown in FIG. 10C, when the card 81 is further pushed in, the latching state of the latch pin 57 and the heart cam groove 69 is released, and the slide member 55 is pushed back together with the card 81 in the ejecting direction. When the slide member 55 is slid in the ejecting direction, the holding portion 67 of the retaining member 56 is pushed out to the rear end of the card 81, and the retaining member 56 is swung in the retracting direction around the support hole.

  As shown in FIG. 10D, when the card 81 is ejected from the card connector 51 and the slide member 55 is slid to the ejection position, the holding portion 67 of the retaining member 56 is moved to the retracted position. Thereby, the holding part 67 of the retaining member 56 is retracted from the mounting opening side, and the card 81 can be inserted into and removed from the card 81 connector.

  Thus, in conjunction with the slide of the slide member 55 to the discharge position, the holding portion 67 of the retaining member 56 is moved to the retracted position. Accordingly, the card 81 is ejected, so that the retaining member 56 is unlocked, and the card 81 is not restricted from being ejected from the card connector 51.

  As described above, according to the card connector 51 according to the present embodiment, it is possible to reliably prevent the card 81 from being removed from the card connector 51, as in the first embodiment, and to remove the card 81. The stop member 56 does not prevent the card 81 from being discharged. Further, since manual operation with respect to the retaining member 56 is not required, the card 81 can be easily mounted and ejected. Further, since the holding portion 67 is pushed out to the retracted position by the card 81 when the card 81 is ejected, it is possible to prevent the card 81 from being smoothly ejected and unexpectedly popped out. Furthermore, by using the side surface 65 of the lever 66 as a cam driven surface, it is possible to increase the component strength against the pressing force from the cam portion 64 even when the thin retaining member 56 is used. Further, since the strength of the parts is enhanced, the retaining member 56 can be formed thin, and the card connector 51 can be thinned.

  The card connector according to the first and second embodiments can be provided with a delay mechanism that delays the movement of the holding portion to the retaining position with respect to the slide to the mounting position of the slide member. is there. Here, the delay mechanism will be described with reference to FIGS. FIG. 11 is an explanatory diagram of the delay mechanism according to the embodiment of the present invention. FIG. 12 is an explanatory diagram of a delay operation by the delay mechanism according to the embodiment of the present invention. In FIG. 11 and FIG. 12, for the sake of convenience of explanation, a connection configuration different from the first and second embodiments will be exemplified and described.

  As shown in FIG. 11, a protruding portion 79 that protrudes toward the bottom wall portion of the connector main body 72 is formed at the distal end portion of the connecting portion 71. The protruding portion 79 is formed between the side wall portion 73 of the connector main body 72 with a space that can accommodate the lever 75 of the retaining member 74. The projecting portion 79 extends in the sliding direction of the slide member 84 and functions as a cam portion for driving the retaining member 74, and also comes into contact with a spring portion 78 of the retaining member 74 described later to drive the retaining member 74. It functions as an abutting portion that delays.

  The retaining member 74 is formed of a metal plate, and includes a lever 75 having a substantially arc shape when viewed from above, and a holding portion 76 provided on the distal end side of the lever 75. The lever 75 is swingably supported by a support protrusion 77 provided on the bottom wall portion. The rear end side of the side surface 85 of the lever 75 is a contact surface that contacts the protrusion 79. When the rear end side of the side surface 85 of the lever 75 is pressed by the projecting portion 79, the retaining member 74 is swung in the retaining direction around the support hole.

  In addition, the lever 75 is provided with a cantilevered spring portion 78 that abuts against the protruding portion 79 at the ejection position of the card 81. The spring portion 78 abuts against the protruding portion 79 to urge the retaining member 74 in the retracting direction. In this case, the protruding portion 79 that is in contact with the spring portion 78 extends from the tip of the connecting portion 71 by a predetermined length in the insertion direction. Therefore, the spring portion 78 resists the swinging of the retaining member 74 in the retaining direction by a predetermined length from the tip of the connecting portion 71 when the sliding member 84 slides to the mounting position.

  Therefore, the retaining member 74 is delayed in the retaining direction with respect to the slide of the slide member 84 only while the spring portion 78 and the projecting portion 79 are in contact with each other. The delay amount can be adjusted by the extension length of the protruding portion 79 in the sliding direction. For example, the delay amount is preferably adjusted to a length that absorbs a dimensional error in the insertion direction of the card 81.

  As shown in FIG. 12A, when the slide member 84 is in the ejection position, the card 81 is pushed out from the mounting opening together with the slide member 84. At this time, the retaining member 74 positions the holding portion 76 at the retracted position. When the card 81 is pushed from this state, the projecting portion 79 is moved in the insertion direction as the slide member 84 slides in the insertion direction.

  As shown in FIG. 12B, when the card 81 is further pushed in and the slide member 84 is further slid in the insertion direction, the projecting portion 79 comes into contact with the rear end side of the side surface 85 of the lever 75, and the retaining member 74 is pressed in the retaining direction. At this time, the retaining member 74 is urged in the retracting direction by the contact between the spring portion 78 and the protruding portion 79, so that swinging in the retaining direction is suppressed.

  As shown in FIG. 12C, when the card 81 is further pushed in and the slide member 84 is further slid in the insertion direction, the spring portion 78 is detached from the protruding portion 79, and the retaining member 74 is swung in the retaining direction. Start moving. With such a configuration, it is possible to delay the swinging of the retaining member 74 in the retaining direction with respect to the sliding direction of the slide member 84 toward the mounting position. Therefore, even when the long card 81 is inserted in the insertion direction, the movement of the holding unit 76 to the retaining position is delayed to prevent the holding unit 76 and the card 81 being inserted from colliding, The card 81 can be installed smoothly.
