Description

Connector for Cards {CONNECTOR FOR CARD}

The present invention relates to a connector for a card, and more particularly to a connector for a card for a subscriber identity module (SIM) card.

Background Art Conventionally, a push-push card connector is known as a card connector for a SIM card (see Patent Document 1, for example). The locking mechanism for locking the slide member which slides together with a SIM card in an insertion direction and a discharge direction in a housing | casing in the connector for cards of patent document 1 in a mounting position is provided. The locking mechanism locks the slide member at the mounting position by pushing the SIM card, and releases the lock of the slide member by further pushing the SIM card. When the lock of the slide member is released, the SIM card is pushed back to the discharge position through the slide member by the elastic support force of the discharge spring that elastically supports the slide member in the discharge direction.

By the way, the notch for holding | maintenance for preventing the deviation | deviation from a slide member is not formed in the side surface of a SIM card. Therefore, even if the slide member is locked at the mounting position, there is a possibility that the SIM card may come out of the connector due to vibration or the like. For this reason, the structure which forms the fall prevention member for fall prevention in the mounting opening side of a card connector can be considered (for example, refer patent document 2). The fall prevention member of the connector for cards of patent document 2 moves between the fall prevention position which blocks a part of a mounting opening, and the retracted position which retracts from a fall prevention position by manual operation. The SIM card is prevented from being pulled out of the connector by moving to the pullout prevention position of the pullout prevention member, and the SIM card is allowed to be inserted into and pulled out of the connector by moving to the retracted position of the pullout prevention member.

Japanese Laid-Open Patent Publication 2003-17183 Japanese Patent Publication No. 2717349

However, in the above-mentioned conventional card connector, since the release preventing member is manually operated, there is a possibility that the operation of the release preventing member may be forgotten when the SIM card is attached, and the problem that the SIM card can not be prevented from being reliably prevented is prevented. there was. In addition, when the SIM card is inserted, it is necessary to manually remove the SIM card to prevent it from being pulled out after the SIM card is inserted. Therefore, there existed a problem that operation became complicated.

In addition, the pull-out preventing member of the above-mentioned conventional card connector moves between the pull-out prevention position and the retracted position by sliding in the width direction orthogonal to the insertion direction. A guide extending in the width direction is formed on the release preventing member, and is loosely engaged with the guide groove formed in the housing. Therefore, when there is a deviation in the size of the SIM card and the size in the insertion direction is larger than the prescribed size, the release preventing member does not have looseness in the insertion direction, so that the SIM card can be reliably removed. There was no.

The present invention has been made in view of such a situation, and even if a card having no retaining notch for preventing deviation from the slide member is used, it is possible to reliably remove the card at the time of card insertion without requiring complicated operation. It is an object to provide a connector for a card that can be prevented.

The card connector of the present invention is slidably formed in the housing together with the card in a housing forming a mounting space of the card, and in the insertion direction and the discharge direction of the card, and the card is pushed into the mounting space. The slide member held at the mounting position by the additional position from the mounting position and returned to the discharge position by the additional pushing from the mounting position, and the holding portion for preventing the card from being pulled out; And a release preventing member for moving between the retracting positions to be evacuated from the preventing position, the release preventing member being interlocked with the slide of the slide member via a connecting portion formed in the slide member, and to the mounting position of the slide member. The holding portion to the release preventing position by sliding It is characterized by moving.

According to this structure, the holding | maintenance part of a fall prevention member is moved to a fall prevention position in conjunction with the slide to a mounting position of a slide member. Therefore, at the time of card insertion, even if the operation of the release preventing member is forgotten, the holder is moved to the release prevention position, so that the card can be reliably prevented from being pulled out of the card connector by the holder. In addition, since manual operation of the release preventing member becomes unnecessary, the card mounting operation can be easily performed.

In the card connector, the release preventing member moves the holding part to the retracted position by sliding the slide member to the discharge position.

According to this configuration, in conjunction with the slide to the discharge position of the slide member, the holding portion of the release preventing member is moved to the retracted position. Therefore, at the time of ejecting the card, the holder is moved to the retracted position without operating the release preventing member, so that the ejection of the card is not impeded by the holder. In addition, since manual operation of the release preventing member becomes unnecessary, the card ejection operation can be performed simply.

The present invention further provides a delay mechanism for delaying the movement of the holding portion to the dropping prevention position with respect to the slide of the slide member to the mounting position by the release preventing member and the connecting portion in the card connector. It is characterized by.

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 prevention position of the holding, the collision between the holding portion and the card during insertion can be prevented and the card can be loaded smoothly.

Moreover, in the said card connector, the said delay mechanism has the spring part formed in the said release prevention member, and the contact part formed in the said connection part, and the contact part which can contact the said spring part, The said slide member is The holding portion is elastically supported toward the retracted position side by the spring portion in contact with the abutting portion while sliding from the discharge position by the predetermined length, thereby slowing the movement to the release preventing position of the holding portion. do.

According to this structure, the movement timing of a holding | maintenance part can be delayed by the contact of a spring part and a contact part, and a delay mechanism can be comprised with a simple structure.

Moreover, in this card connector, a coalescing part is formed in either one of the said anti-logging member and the said connection part, and the other is driven in contact with the said coalescing part, and drives the said anti-logging member. A drive surface is formed, and the said release prevention member is characterized in that the said carbon contact part and the said drive surface are firmly contacted by the slide to the said mounting position of the said slide member, and the said holding part is moved to the said removal prevention position, It is characterized by the above-mentioned.

According to this configuration, since the contact preventing portion and the driving surface can be moved finely while maintaining the connection, the contact preventing portion and the driving surface can be moved, thereby absorbing the dimensional deviation in the insertion direction of the card, thereby preventing the card from being removed. I can do it. In addition, even when the card connector is mounted on the vehicle, vibrations applied from the outside can be absorbed by the impact contact between the contact portion and the driving surface, thereby reducing the occurrence of noise such as rattle noise.

The present invention is also characterized in that in the card connector, the release preventing member is made of a metal plate and integrally formed with the bullet contact portion.

According to this structure, a carbon contact part can be integrally formed in the fall prevention member by bending of a metal plate, etc., and strength can be raised.

Moreover, in this card connector, the said drive surface is formed in the side surface of any one of the said release prevention member and the said connection part, It is characterized by the above-mentioned.

According to this structure, even if it uses a thin fall prevention member and a connection part, by using a side as a drive surface, the component strength with respect to the pressing force from the side can be raised. Moreover, since a thin fall prevention member and a connection part can be used, a card connector can be made thin.

Moreover, in the said card connector, the cam mechanism is formed by the cam follower surface formed in the said fall prevention member, and the cam part formed in the said connection part, and contacting the cam follower surface, The said fall prevention member, The slide in the insertion direction of the slide member is converted by the cam mechanism to move the holding portion to the release preventing position.

According to this structure, the slide to the insertion prevention position of a holding | maintenance part and a slide in the insertion direction can be interlocked with a simple structure.

In the card connector, the release preventing member is configured to convert a slide in the discharge direction of the slide member by the cam mechanism to move the holding part to the retracted position.

According to this structure, the movement to the retracted position of the slide and the holding part in the discharge direction of the slide member can be linked with a simple structure.

In the card connector, the release preventing member is supported by the housing so as to be swingable, and the slide of the slide member is converted by the cam mechanism to swing the holding part. do.

According to this structure, the part which can abut on the card of a holding | maintenance part can be taken large, without widening the width | variety of a card connector by rocking a fall prevention member.

The present invention is also characterized in that in the card connector, the cam follower surface is formed on the side surface of the fall prevention member.

According to this structure, even if a thin fall prevention member is used, the side strength of a fall prevention member is made into a cam follower surface, and the component strength with respect to the pressing force from the side can be raised. In addition, since the thin release preventing member can be used, the card connector can be thinned.

The present invention further provides a stopper for restricting movement of the slide member in a discharge direction of the card connector, wherein the connecting portion extends from the slide member in a discharge direction to bypass the stopper. And the release preventing member is interlocked with the slide of the slide member in the vicinity of a mounting hole of the card.

EMBODIMENT OF THE INVENTION Hereinafter, 1st Embodiment of this invention is described in detail with reference to an accompanying drawing. In addition, below, the case where it applies to the card connector with which a SIM card is mounted is demonstrated. However, the application object of the card connector which concerns on this embodiment is not limited to this, It can change suitably.

First, the card used as a mounting object is demonstrated before demonstrating the card connector which concerns on this embodiment. Fig. 16 is a plan view of a card according to the first embodiment of the present invention, in which (a) is a top view and (b) is a back view, respectively.

As shown in Figs. 16A and 16B, the card 91 is a so-called SIM card, and is a storage medium formed in a substantially rectangular shape when viewed from the top and having an information storage section. At one corner of the card 91, an inclined surface 92 that is cut out and inclined at about 45 degrees is formed. The inclined surface 92 is used to identify the insertion direction of the card 91, the side on which the inclined surface 92 is formed becomes the front end side in the insertion direction, and the opposite side is the rear end side in the insertion direction. do.

On the back surface of the card 91, a plurality of contact terminals 15 of the card connector 1 are read or recorded in contact with approximately half of the rear end side in the insertion direction of the card 91. A plurality of contact pads 93 are formed. In addition, the side surface of the card 91 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. In other words, the card 91 is not held by the slide member 6 of the card connector 1 but is operated in the insertion direction and the discharge direction in a state of being in surface contact with the slide member 6.

Next, with reference to FIG. 1 and FIG. 2, the whole structure of the card connector is demonstrated. 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 according to the first embodiment of the present invention removed.

As shown in FIG. 1 and FIG. 2, the card connector 1 according to the present embodiment is attached to a connector main body 2 having an upper surface and a front surface opened, and a card ( The cover 3 which forms the mounting space of 91 is provided, and the connector main body 2 and the cover 3 are combined and it forms the box-shaped body which has the mounting opening 4. As shown in FIG. A plurality of contact terminals 15 are formed in the substantially first half portion on the mounting port 4 side in the bottom wall portion 11 of the connector main body 2. Each contact terminal 15 extends from the substantially first half of the bottom wall portion 11 toward the inner wall portion 12 side.

In the inner wall portion 12 of the connector main body 2, a switch portion 5 for detecting the mounting of the card 91 is formed. The switch portion 5 has a lever 21 supported on the inner wall portion 12 so as to be swingable, and a contact spring 22 formed on the lever 21. The switch part 5 opposes a pair of fixed contacts 23 and 24 exposed to the inner side surface of the inner wall part 12, and one end of the contact spring 22 is unmounted when the card 91 is not mounted. Is made in contact with the fixed contact 23, and the other end of the contact spring 22 is separated from the other fixed contact 24. And when the switch part 5 is pushed in to the inner wall part 12 side by the card 91, the other end of the contact spring 22 is rotated to the other fixed contact 24 by the rotational motion of the lever 21. The contact of the card 91 is detected by contact.

On one side wall portion 13 side of the connector body 2, a slide member 6 slidable along the side wall portion 13 and a coil-shaped discharge spring 7 which is stretched with the slide of the slide member 6. ) Is formed. The discharge spring 7 has one end abutting against the inner wall portion 12, and the other end abuts against the slide member 6, and elastically supports the slide member 6 in the discharge direction. Moreover, the stopper 26 is formed in the mounting opening 4 side of the connector main body 2 so that the slide to the discharge direction of the slide member 6 may be interrupted | blocked. The stopper 26 restricts the slide member 6 to the discharge position by contacting the slide member 6.

The slide member 6 is comprised so that a slide is possible in the insertion direction and the discharge direction in the state elastically supported by the discharge spring 7. The slide member 6 has the arm part 31 extended toward the center of the connector main body 2 from the front end side of an insertion direction. The arm part 31 abuts against the front end surface of the card 91 in the insertion direction to operate the slide member 6 and the card 91 integrally.

The heart cam groove 39 is formed in the upper surface of the slide member 6, and the position of the slide member 6 is defined by the latch pin 8 formed in the heart cam groove 39 and the stopper 26. . The latch pin 8 extends in the slide direction of the slide member 6, and both ends are bent at approximately right angles 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 onto the heart cam groove 39 of the slide member 6.

The heart cam groove 39 has a plurality of steps and inclinations and is formed in a heart-shaped annular shape when viewed from above, and slides the other end of the latch pin 8 in one direction according to the slide of the slide member 6. Let's do it. When the slide member 6 is pushed into the mounting position near the inner wall portion 12, the other end of the latch pin 8 is caught by the engaging portion of the heart cam groove 39, and the elastic spring is held by the elastic support. The return of the slide member 6 is regulated. When the slide member 6 is pushed further in this state, the latching state of the latch pin 8 and the heart cam groove 39 is released, and the slide member 6 is returned by the elastic support of the discharge spring 7. do. Thus, the latch pin 8 and the heart cam groove 39 have a holding function in the mounting position of the slide member 6.

In addition, the slide member 6 is provided with a connecting portion 32 extending through the side of the stopper 26 to the mounting opening 4 side. In the vicinity of the distal end of the connecting portion 32, a release preventing member 9 which interlocks with the slide member 6 is formed. The fall prevention member 9 has the holding piece 44 which hold | maintains the card 91 with a fall prevention. Moreover, the fall prevention member 9 interlocks with the slide member 6 via the connection part 32, and is a holding piece between the fall prevention position which blocks a part of the mounting opening 4, and the retracted position withdrawn from a fall prevention position. Move (44).

The cover 3 is formed by bending a metal plate, and a pin pressing portion 35 for pressing the latch pin 8 is formed on one side of the upper plate. The pin pressing portion 35 is a cantilever spring cut off toward the bottom wall portion 11 side, and presses the middle portion of the latch pin 8 downward to lower the other end of the latch pin 8 into the heart cam groove 39. Hold down.

Hereinafter, with reference to FIG. 3 and FIG. 4, the linkage structure of a slide member and a fall prevention member is demonstrated. It is explanatory drawing of the interlocking structure of the slide member which concerns on the 1st Embodiment of this invention, and a fall prevention member. 4 is an explanatory diagram of a rocking state of the release preventing member when a card having a dimensional error according to the first embodiment of the present invention is attached. 3, the interlocking state of the slide member and the fall prevention member at the time of card discharge | emission is shown.

As shown in FIG. 3, the connecting portion 32 is formed so as to extend to the mounting opening 4 side so as to bypass the stopper 26 and to come into contact with the release preventing member 9. For this reason, the slide member 6 and the fall prevention member 9 are not restrict | limited by the stopper 26 in the vicinity of the mounting opening 4. The inclined surface 33 which can transmit the slide of the slide member 6 to the spring piece 43 of the fall prevention member 9 is formed in the front-end | tip part of the connection part 32. As shown in FIG. The inclined surface 33 is inclined so that the space | interval with the side wall part 13 may be narrowed toward the mounting opening 4 side. And the inclined surface 33 presses the spring piece 43 of the fall prevention member 9 by moving with the slide of the slide member 6. As shown in FIG.

The fall prevention member 9 is formed by bending a metal plate, and has a flat plate portion 42 supported so as to be able to swing freely on the support protrusion 41 formed on the bottom wall portion 11 of the connector body 2. . The cantilever spring piece 43 is formed in the inner wall part 12 side of the flat plate part 42. As shown in FIG. The spring piece 43 extends toward the stopper 26 from the base end connected to the flat plate part 42, and is folded back to the base end side in the middle part of an extension direction. As the free end side of the spring piece 43 is pressed against the inclined surface 33 of the connecting portion 32, the release preventing member 9 is swung around the support protrusion 41.

On the mounting opening 4 side of the flat plate portion 42, a holding piece 44 for preventing the card 91 from being pulled out is formed. The holding piece 44 extends from the base end connected to the flat plate part 42 toward the mounting opening 4 side (card 91 side), and is bent from the middle portion to the base end side. The holding piece 44 prevents the card 91 from being pulled out at approximately half of the base end side. Approximately half of the end of the holding piece 44 is bent to avoid contact with the card 91 at the retracted position.

In addition, the spring piece 43 vicinity of the flat plate part 42 regulates the fluctuation range of the fall prevention member 9 with the 1st, 2nd restriction parts 48 and 49 formed in the connection part 32. FIG. It is piece 45. The restricting piece 45 is located in the step portion 47 that is one step lower than the first and second restricting parts 48, 49 in the connecting portion 32. And the fall prevention member 9 is restrict | limited the fluctuation | movement to a fall prevention direction by the restricting piece 45 and the 1st restriction part 48, when the slide member 6 is in a discharge position. Thereby, the holding piece 44 does not move to the fall prevention position at the time of non-mounting of the card 91, and mounting of the card 91 is not impaired. Moreover, the fall prevention member 9 is restrict | limited the fluctuation | movement to the retracting direction by the restricting piece 45 and the 2nd restriction part 49, when the slide member 6 is in a mounting position. Thereby, the holding piece 44 does not move to a retracted position at the time of mounting of the card 91, and the removal of the card 91 is reliably prevented.

The fall prevention member 9 comprised in this way absorbs the dimension error in the insertion direction of the card 91 by the contact of the spring piece 43 and the inclined surface 33 of the connection part 32. As shown in FIG. Hereinafter, with reference to FIG. 4, the rocking state of the fall prevention member when the card which has a dimension error is mounted is demonstrated. 4 is an explanatory diagram of a rocking state of the release preventing member when a card having a dimensional error according to the embodiment of the present invention is attached. In addition, in FIG. 4, (a) has shown the state in which the card of the specified dimension was mounted in the card connector, and (b) has shown the state in which the card which has a dimension error was mounted in the card connector.

As shown in Fig. 4A, when the card 91 of the prescribed size is attached to the connector 1 for a card, the release preventing member 9 is connected to the contact between the spring piece 43 and the inclined surface 33. The holding piece 44 is moved to the fall prevention position by this. At this time, the holding piece 44 is in surface contact with the rear end surface in the insertion direction of the card 91 and prevents the card 91 from being pulled out.

On the other hand, as shown in FIG.4 (b), when the card 91 in which the dimension in the insertion direction is larger than the prescribed dimension is attached to the card connector 1, the fall prevention member 9 is a spring piece ( The holding piece 44 is moved toward the fall prevention position by the contact between 43 and the inclined surface 33. The holding piece 44 moved toward the release preventing position abuts against the rear end face of the card 91 at a position slightly ahead of the release prevention position (the angle) by the amount where the card 91 protrudes from the prescribed dimension. . At this time, the spring piece 43 is bent larger than the case where the card 91 of the prescribed size is mounted, thereby adjusting the fall prevention member 9 to an appropriate amount of swing while absorbing the error of the card 91.

In this way, when the card 91 is mounted, the spring preventing member 43 and the connecting portion 32 can be moved while keeping the connection due to the contact between the spring piece 43 and the inclined surface 33. By absorbing the dimensional deviation in the insertion direction of the 91, it is possible to reliably prevent the card 91 from being pulled out. In addition, even when the card connector 1 is mounted, the vibration applied from the outside can be absorbed by the contact between the spring piece 43 and the inclined surface 33, thereby reducing the occurrence of noise such as rattle noise. .

Here, the rocking | movement operation | movement of a fall prevention member is demonstrated with reference to FIG. 5 is a transition diagram of the rocking motion of the release preventing member according to the first embodiment of the present invention. In Fig. 5, (a) to (c) show rocking motions of the fall prevention member when the card is loaded, and (c) to (e) show rocking motions of the fall prevention member when the card is ejected, respectively. have.

As shown in FIG. 5A, when the slide member 6 is in the discharge position, the card 91 is pushed out of the mounting opening 4 by the slide member 6. At this time, the fall prevention member 9 places the holding piece 44 in the retracted position, and the fluctuation in the fall prevention direction is restricted by the restricting piece 45 and the first restricting portion 48. When the card 91 is pushed in this state, the slide member 6 slides in an insertion direction, and the spring piece 43 of the fall prevention member 9 and the inclined surface 33 of the connection part 32 contact.

As shown in FIG.5 (b), when the card 91 is further pushed in and the slide member 6 slides further in the insertion direction, the spring piece 43 will start to ride up the inclined surface 33. As shown in FIG. The fall prevention member 9 starts oscillation in the fall prevention direction centering on the support protrusion 41 by pushing in the inclined surface 33 with respect to the spring piece 43. As shown in FIG. At this time, the fall prevention member 9 is not restricted from fluctuation because the restricting piece 45 and the first restricting portion 48 are separated from each other.

As shown in Fig. 5 (c), when the card 91 is mounted to the connector 1 for the card and the slide member 6 slides to the mounting position, the spring piece 43 completely covers the inclined surface 33. Ride up The fall prevention member 9 moves the holding piece 44 to a fall prevention position by the shaking of a fall prevention direction. Thereby, the holding piece 44 of the fall prevention member 9 protrudes toward the mounting opening 4 side, and the fall of the card 91 from the card connector 1 is prevented. At this time, the fall prevention member 9 is regulated by the restricting piece 45 and the 2nd restriction part 49 and the fluctuation | variation of the retraction direction. Therefore, forcibly removing the card 91 from the card connector 1 is prevented.

In this way, in conjunction with the slide to the mounting position of the slide member 6, the holding piece 44 of the fall prevention member 9 is moved to the fall prevention position. Therefore, the removal prevention of the card 91 from the card connector 1 can be reliably prevented because the removal prevention member 9 prevents the removal of the card 91.

When the card 91 is pushed further in the state shown in FIG. 5 (c), the slide member 6 is pushed back in the discharge direction together with the card 91 to prevent the member from being pulled out by the second restricting portion 49. The fluctuation regulation in the retraction direction of (9) is canceled.

As shown in Fig. 5 (d), when the slide member 6 slides in the discharge direction, the holding piece 44 of the release preventing member 9 is pushed in by the rear end of the card 91. The fall prevention member 9 starts rocking | fluctuation in the retracting direction centering on the support protrusion 41 by pushing out the card 91 with respect to the holding piece 44. As shown in FIG. At this time, since the spring piece 43 descends the inclined surface 33, the amount of pushing of the inclined surface 33 with respect to the spring piece 43 becomes small, and the spring to the fluctuation of the retraction direction of the fall prevention member 9 is reduced. The resistance of the piece 43 weakens.

As shown in FIG. 5E, when the card 91 is discharged from the card connector 1 and the slide member 6 slides to the discharge position, the release preventing member 9 is moved by swinging in the retraction direction. The holding piece 44 is moved to the retracted position. Thereby, the holding piece 44 of the fall prevention member 9 is withdrawn from the mounting opening 4 side, and insertion of the card 91 with respect to the card connector 1 is allowed. At this time, the fall prevention member 9 is restricted by the restriction | regulation piece 45 and the 1st control part 48 of the connection part 32 with the fluctuation | variation of a fall prevention direction.

In this way, in conjunction with the slide to the discharge position of the slide member 6, the holding piece 44 of the release preventing member 9 is moved to the retracted position. Therefore, the release prevention of the release preventing member 9 is released by the discharge operation of the card 91, so that the discharge of the card 91 from the card connector 1 is not restricted.

6 and 7, the attaching operation and the ejecting operation of the card connector will be described. 6 is an explanatory diagram of a card mounting operation by the card connector according to the first embodiment of the present invention. 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 91 by the card connector 1 will be described. As shown in FIG. 6A, when the card 91 is inserted into the connector 1 for a card, the tip of the card 91 comes into contact with the arm portion 31 of the slide member 6. At this time, since the fluctuation | movement of the fall prevention direction is restrict | limited by the 1st restriction part 48, the fall prevention member 9 does not prevent insertion of the card 91. When the card 91 is pushed in this state, the slide member 6 slides toward a mounting position, and the fluctuation | limiting of the fall prevention direction of the fall prevention member 9 is canceled | released.

As shown in FIG. 6 (b), when the card 91 is further pushed in, the slide member 6 is further slid to the mounting position side while the heart cam groove 39 is slid to the other end of the latch pin 8. . With the slide in the insertion direction of this slide member 6, the spring piece 43 of the fall prevention member 9 is pushed in the inclined surface 33 of the connection part 32, and the fall prevention member 9 is supported. It swings around the projection 41 in the fall prevention direction.

As shown in Fig. 6 (c), when the card 91 is further pushed in, the other end of the latch pin 8 is caught by the engaging portion of the heart cam groove 39, so that the card 91 is the slide member 6. Is held in the mounting position with the. And the holding piece 44 of the fall prevention member 9 is moved to the fall prevention position, and the fall of the card 91 from the card connector 1 is prevented. Moreover, the switch part 5 is pushed in by the card 91, and mounting of the card 91 is detected. The contact pad 93 of the card 91 comes into contact with the contact terminal 15 of the card connector 1 by being held at the mounting position, and thus the signal between the information storage section of the card 91 and the host device is maintained. Sorghum becomes possible.

Next, the ejection operation of the card 91 by the card connector 1 will be described. As shown in FIG. 7A, in the attached state of the card 91, the other end of the latch pin 8 is caught by the engaging portion of the heart cam groove 39, and is moved to the discharge direction of the slide member 6. The slide is regulated. At this time, the fall prevention member 9 is prevented from forcibly removing the card 91 because fluctuations in the retracting direction are restricted by the second restricting portion 49.

As shown in FIG. 7B, when the card 91 is further pushed in, the latching state of the latch pin 8 and the heart cam groove 39 is released, and the slide member 6 is discharged. Is pushed back toward the discharge position. By the slide of the slide member 6 in the discharge direction, the retaining piece 44 of the fall prevention member 9 is pushed out at the rear end of the card 91, and the fall prevention member 9 moves the support protrusion 41. It swings in the retraction direction with the center as the center.

As shown in Fig. 7 (c), when the slide member 6 slides to the discharge position, the holding piece 44 of the release preventing member 9 moves to the retracted position by pushing out by the card 91. do. In this way, the card 91 is discharged from the mounting port 4 of the card connector 1. In addition, since the pushing by the card 91 to the switch section 5 is released, the ejection of the card 91 is detected. Then, the card 91 is moved from the mounting position to the discharge position so that the contact pad 93 of the card 91 is separated from the contact terminal 15 of the connector 1 for the card.

As described above, according to the card connector 1 according to the present embodiment, the sliding member 6 is interlocked with the slide to the mounting position and is pushed onto the inclined surface 33 of the connecting portion 32 to prevent the fall out. The holding piece 44 of the member 9 is moved to the fall prevention position. Therefore, the removal prevention of the card 91 from the card connector 1 can be reliably prevented because the removal prevention member 9 prevents the removal of the card 91. In addition, in conjunction with the slide to the discharge position of the slide member 6, the holding piece 44 of the release preventing member 9 is moved to the retracted position by being pressed by the card 91. Therefore, the release prevention of the release preventing member 9 is released by the discharge operation of the card 91, so that the discharge of the card 91 from the card connector 1 is not impeded. In addition, since manual operation on the release preventing member 9 becomes unnecessary, the mounting operation and the discharge operation of the card 91 can be easily performed.

In addition, since the holding piece 44 is moved to the retracted position by abutting the card 91 moved in the discharge direction, the card 91 can be discharged smoothly, and the operability can be improved. In addition, since the card 91 is braked by the contact with the holding piece 44 at the time of ejection of the card 91, an unintended popping of the card 91 can be prevented. In addition, since the contact prevention member 43 and the inclined surface 33 are in contact with each other, the release preventing member 9 and the connecting portion 32 can finely move while maintaining the connection, so that the dimensions in the insertion direction of the card 91 are adjusted. By absorbing the deviation, it is possible to reliably prevent the card 91 from being pulled out. In addition, even when the card connector 1 is mounted, vibrations applied from the outside can be absorbed by the contact between the contact spring 43 and the inclined surface 33 to reduce the occurrence of noise such as rattle noise. Moreover, even if it uses the thin fall prevention member 9 and the connection part 32, by making a side surface into the inclined surface, the component strength with respect to the pressing force from the side can be raised. In addition, since the thin release preventing member 9 and the connecting portion 32 can be used, the card connector 1 can be thinned.

Next, a second embodiment of the present invention will be described. The card connector according to the second embodiment of the present invention differs only in the interlocking configuration of the card connector, the slide member, and the release preventing member according to the first embodiment described above. Therefore, only the difference is described in particular. 8 is a perspective view of the card connector with the cover according to the second embodiment of the present invention removed. 9 is an exploded perspective view of the slide member and the release preventing member according to the second embodiment of the present invention. It is explanatory drawing of the interlocking structure of the slide member which concerns on 2nd Embodiment of this invention, and a fall prevention member.

As shown in FIG. 8, the card connector 51 has the same structure as the card connector shown in 1st Embodiment except the slide member 55 and the fall prevention member 56. As shown in FIG. The slide member 55 is slidably arranged along one side wall portion 58 of the connector body 52 and is elastically supported in the discharge direction by a discharge spring (not shown). Moreover, the stopper 61 which regulates the slide of the slide member 55 is formed in the front in the discharge direction of the slide member 55. As shown in FIG. In the vicinity of the stopper 61, an anti-falling member 56 is formed in cooperation with the slide member 55 to prevent the card 91 from being pulled out.

As shown in FIG. 9, the slide member 55 is provided with the connection part 62 extended to a mounting opening side, and the connection part 62 is formed with the opening 63 which can accommodate the stopper 61. As shown in FIG. . For this reason, the sliding member 55 and the fall prevention member 56 do not restrict | limit a linkage by the stopper 61 in the vicinity of a mounting opening. In addition, since the stopper 61 is disposed in the opening 63, the connector 51 for the card can be made thin in comparison with the configuration in which the connecting portion 62 is bypassed so as to pass above the stopper 61.

At the distal end of the connecting portion 62, a connecting pin 64 protruding toward the bottom wall portion 59 side is formed. The connecting pin 64 is disposed in the cam groove 65 formed on the upper surface of the fall prevention member 56, and moves out of the cam groove 65 with the slide of the slide member 55, thereby preventing the fall prevention member 56. ). That is, the cam mechanism is formed by the connecting pin 64 which functions as a cam part, and the guide surface of the cam groove 65 which functions as a cam follower surface.

The fall prevention member 56 has the lever 66 which is substantially circular arc shape from the upper surface, and the holding part 67 formed in the front end side of the lever 66. As shown in FIG. On the back surface of the lever 66, the rocking projection 68 protrudes toward the bottom wall portion 59 side. The fall prevention member 56 is supported by the bottom wall 59 so that rocking | swinging is possible by inserting into the support hole formed in the bottom wall part 59 the rocking protrusion 68. FIG. The above-mentioned arc-shaped cam groove 65 is formed in the upper surface of the lever 66, and the opposing surface which forms the cam groove 65 is a guide surface which guides the connecting pin 64. As shown in FIG. This arc-shaped cam groove 65 is pushed by the connecting pin 64 of the connecting portion 62, so that the release preventing member 56 swings around the support hole.

As shown in Fig. 10A, when the slide member 55 is in the discharge position, the connecting pin 64 is located at one end side of the cam groove 65 near the holding part 67, and the holding part 67 is located at the retracted position. When the card 91 is pushed in this state, the slide member 55 slides in the insertion direction, and the connecting pin 64 of the connecting portion 62 moves in the cam groove 65 from one end to the other end side. do. Then, when the connecting pin 64 is brought into sliding contact with the guide surface on the other end side of the cam groove 65, the release preventing member 56 swings around the support hole in the release preventing direction.

As shown in Fig. 10 (b), when the card 91 is further pushed in and the slide member 55 slides to the mounting position, the holding portion 67 of the release preventing member 56 is moved to the release preventing position. . Thereby, the holding | maintenance part 67 protrudes to the mounting opening side, and the card 91 from the card connector 51 is prevented from being pulled out. In addition, the other end of the latch pin 57 is caught by the engaging portion of the heart cam groove 69, so that the card 91 is held together with the slide member 55 in the mounting position.

In this way, in conjunction with the slide to the mounting position of the slide member 55, the holding portion 67 of the release preventing member 56 is moved to the release preventing position. Therefore, the removal prevention of the card 91 from the card connector 51 can be reliably prevented because the removal prevention member 56 prevents the removal of the card 91.

As shown in FIG. 10 (c), when the card 91 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 connected with the card 91. It is pushed back in the discharge direction together. When the slide member 55 slides in the discharge direction, the connecting pin 64 moves inside the cam groove 65 from the other end side to the one end side. Then, when the connecting pin 64 is in sliding contact with the guide surface on the one end side of the cam groove 65, the release preventing member 56 swings around the support hole in the retracting direction.

As shown in Fig. 10 (d), when the card 91 is discharged from the card connector 51 and the slide member 55 slides to the discharge position, the holding portion 67 of the release preventing member 56 is removed. Move to the retracted position. Thereby, the holding | maintenance part 67 is retracted from the mounting opening side, and insertion of the card 91 with respect to the card connector 51 is allowed.

In this way, in conjunction with the slide to the discharge position of the slide member 55, the holding portion 67 of the release preventing member 56 is moved to the retracted position. Therefore, the release prevention of the release preventing member 56 is released by the discharge operation of the card 91, so that the discharge of the card 91 from the card connector 51 is not restricted.

As described above, according to the card connector 51 according to the present embodiment, like the first embodiment, it is possible to reliably prevent the card 91 from being removed from the card connector 51 and to be removed. The prevention member 56 does not inhibit the ejection of the card 91. In addition, since manual operation on the release preventing member 56 is no longer necessary, the mounting operation and the discharge operation of the card 91 can be easily performed. Moreover, the interlocking structure of the slide member 55 and the fall prevention member 56 can be formed with a simple structure.

Next, a third embodiment of the present invention will be described. The card connector according to the third embodiment of the present invention differs only in the interlocking configuration of the card connector, the slide member, and the release preventing member according to the first and second embodiments described above. Therefore, only the difference is described in particular. Fig. 11 is a perspective view of the card connector with the cover according to the third embodiment of the present invention removed. 12 is a plan view of the slide member and the release preventing member according to the third embodiment of the present invention. It is explanatory drawing of the interlocking structure of the slide member and pull-out prevention member which concerns on 3rd Embodiment of this invention.

As shown in FIG. 11, the card connector 71 has the same configuration as the card connector shown in the first and second embodiments except for the slide member 75 and the release preventing member 76. The slide member 75 is slidably arranged along one side wall portion 78 of the connector main body 72 and is elastically supported in the discharge direction by a discharge spring (not shown). Moreover, the stopper 81 which regulates the slide of the slide member 75 is formed in the front in the discharge direction of the slide member 75. As shown in FIG. In the vicinity of the stopper 81, an anti-falling member 76 is formed in cooperation with the slide member 75 to prevent the card 91 from being pulled out.

As shown in FIG. 12, the slide member 75 is provided with the connection part 82 extended to a mounting opening side, and the connection part 82 is formed with the opening 83 which can accommodate the stopper 81. As shown in FIG. . For this reason, the slide member 75 and the fall prevention member 76 do not restrict | limit a linkage by the stopper 81 in the mounting opening vicinity. Moreover, since the stopper 81 is arrange | positioned in the opening 83, compared with the structure which bypasses the connection part 82 so that the stopper 81 may pass upward, the card connector 71 can be made thin.

The cam part 84 which protruded toward the bottom wall part 79 side is formed in the front-end | tip part of the connection part 82. As shown in FIG. The cam part 84 is formed at intervals which can accommodate the lever 86 of the fall prevention member 76 between the side wall part 78. The cam part 84 drives the fall prevention member 76 by sliding contact with the side surface 85 of the lever 86 with the slide of the slide member 75. That is, the cam mechanism is formed by the cam part 84 and the side surface 85 of the lever 86 which functions as a cam follower surface.

The fall prevention member 76 has the lever 86 which is a substantially circular arc shape from the upper surface, and the holding part 87 formed in the front end side of the lever 86. As shown in FIG. On the back surface of the lever 86, the rocking projection 88 protrudes toward the bottom wall portion 79 side. The fall prevention member 76 is supported by the bottom wall 79 so that the rocking protrusion 88 is rotatably inserted by the support hole formed in the bottom wall 79 of the connector main body 72. The side surface 85 of the lever 86 extends in substantially circular arc shape, and is a sliding contact surface in sliding contact with the cam portion 84. As the circular arc side surface 85 of this lever 86 is pressed by the cam part 84, the fall prevention member 76 is rocked centering around a support hole.

As shown in FIG. 13A, when the slide member 75 is in the discharge position, the cam portion 84 is in contact with one end of the lever 86 on the holding portion 87 side, and the holding portion 87 Is located in the retracted position. When the card 91 is pushed in this state, the slide member 75 slides in an insertion direction, and the cam part 84 slides the side surface 85 of the lever 86 from one end side to the other end side. And the cam part 84 slides to the other end side of the side surface 85 of the lever 86, and the fall prevention member 76 is rocked in a fall prevention direction centering around a support hole.

As shown in FIG. 13 (b), when the card 91 is further pushed in and the slide member 75 slides to the mounting position, the holding part 87 of the release preventing member 76 is moved to the release preventing position. . Thereby, the holding part 87 protrudes toward the mounting opening side, and the card 91 from being removed from the card connector 71 is prevented. In addition, the other end of the latch pin 77 is caught by the engaging portion of the heart cam groove 89, so that the card 91 is held together with the slide member 75 in the mounting position.

In this way, in association with the slide to the mounting position of the slide member 75, the holding portion 87 of the release preventing member 76 is moved to the release preventing position. Therefore, the removal prevention of the card 91 from the connector 71 for the card can be reliably prevented because the removal prevention member 76 prevents the removal of the card 91.

As shown in FIG. 13 (c), when the card 91 is further pushed in, the latching state of the latch pin 77 and the heart cam groove 89 is released, and the slide member 75 is connected with the card 91. It is pushed back in the discharge direction together. When the slide member 75 slides in the discharge direction, the holding portion 67 of the fall prevention member 56 is pushed out at the rear end of the card 91 so that the cam portion 84 moves the side surface 85 of the lever 86. It moves from the other end side toward one end side. And the cam part 84 makes sliding contact with the one end side of the side surface 85 of the lever 86, and the fall prevention member 76 is rocked in a retraction direction centering on a support hole.

As shown in FIG. 13 (d), when the card 91 is discharged from the card connector 71 and the slide member 75 slides to the discharge position, the holding portion 87 of the release preventing member 76 is moved. Move to the retracted position. Thereby, the holding part 87 of the fall prevention member 76 is withdrawn from the mounting opening side, and insertion of the card 91 with respect to the connector for cards 91 is permitted.

In this way, in conjunction with the slide to the discharge position of the slide member 75, the holding portion 87 of the release preventing member 76 is moved to the retracted position. Therefore, the release prevention of the release preventing member 76 is released by the discharge operation of the card 91, so that the discharge of the card 91 from the card connector 71 is not restricted.

As described above, according to the card connector 71 according to the present embodiment, it is possible to reliably prevent the card 91 from being removed from the card connector 71 similarly to the first and second embodiments. At the same time, the ejection of the card 91 is not inhibited by the release preventing member 76. In addition, since manual operation on the release preventing member 76 is unnecessary, the card 91 can be easily attached and discharged. In addition, since the holding part 67 is pushed out to the retracted position by the card 91 at the time of discharging the card 91, it is possible to prevent the card 91 from being discharged smoothly and unintentionally popping out. Moreover, by making the side surface 85 of the lever 86 into a cam follower surface, even if the thin fall prevention member 76 is used, the component strength with respect to the pressing force from the cam part 84 can be raised. In addition, since the component strength increases as compared with the second embodiment in which the connecting pin 64 is disposed in the cam groove 65, the release preventing member 76 can be formed thin, and the card connector 71 can be made thin. You can do it.

Further, the card connector according to the first, second, and third embodiments described above may be provided with a delay mechanism for delaying the movement of the holding portion to the fall prevention position relative to the slide to the mounting position of the slide member. Here, the delay mechanism will be described with reference to FIGS. 14 and 15. 14 is an explanatory diagram of a delay mechanism according to an embodiment of the present invention. 15 is an explanatory diagram of a delay operation by the delay mechanism according to the embodiment of the present invention. In addition, in FIG.14 and FIG.15, the connection structure different from 1st, 2nd embodiment is demonstrated and demonstrated for convenience of description.

As shown in FIG. 14, the protrusion part 102 which protrudes toward the bottom wall part side of the connector main body 95 is formed in the front-end | tip part of the connection part 94. As shown in FIG. The protruding portion 102 is formed at intervals that can accommodate the lever 98 of the fall prevention member 97 between the side wall portion 96 of the connector main body 95. The protruding portion 102 extends in the slide direction of the slide member 103 and functions as a cam portion for driving the release preventing member 97, and fits into the spring portion 101 of the release preventing member 97 described later. It functions as a contact part which slows the drive of the fall prevention member 97. FIG.

The fall prevention member 97 is formed of the metal plate, and has the substantially 98 arc shaped lever 98 and the holding part 99 formed in the front end side of the lever 98 from the upper surface. The lever 98 is supported so that it can rock freely to the support protrusion 100 formed in the bottom wall part. The rear end side of the side surface 104 of the lever 98 serves as an abutting surface that abuts against the protrusion 102. The rear end side of the side face 104 of the lever 98 is pressed against the protruding portion 102 so that the release preventing member 97 swings around the support hole in the release preventing direction.

In addition, the lever 98 is provided with a cantilever spring portion 101 which abuts against the protrusion 102 at the discharge position of the card 91. The spring portion 101 elastically supports the release preventing member 97 in the retracted direction by abutting the protruding portion 102. In this case, the protruding portion 102 abutting against the spring portion 101 extends from the tip of the connecting portion 94 by a predetermined length in the insertion direction. Therefore, the spring part 101 resists the fluctuation | movement to the fall prevention direction of the fall prevention member 97 by the predetermined length from the front-end | tip of the connection part 94 at the time of the slide to the mounting position of the slide member 103. FIG.

Therefore, the fall prevention member 97 is delayed in the fall prevention direction with respect to the slide of the slide member 103 only while the spring part 101 and the protrusion part 102 contact. In addition, it is preferable to adjust the delay amount by the extension length in the slide direction of the protrusion part 102, and to adjust to the length which absorbs the dimension error in the insertion direction of the card 91, for example.

As shown in FIG. 15A, when the slide member 103 is in the discharge position, the card 91 is pushed out of the mounting opening together with the slide member 103. At this time, the fall prevention member 97 has positioned the holding part 99 in the retracted position. When the card 91 is pushed in this state, with the slide in the insertion direction of the slide member 103, the protrusion 102 is moved in the insertion direction.

As shown in FIG. 15 (b), when the card 91 is further pushed in and the slide member 103 slides further in the insertion direction, the protrusion 102 is placed on the rear end side of the side face 104 of the lever 98. Abuts and presses the fall prevention member 97 to a fall prevention direction. At this time, the fall prevention member 97 is elastically supported in the retracting direction by the abutment of the spring portion 101 and the protruding portion 102, so that the fluctuation in the fall prevention direction is suppressed.

As shown in FIG. 15 (c), when the card 91 is further pushed in and the slide member 103 is further slid in the insertion direction, the spring portion 101 deviates from the protrusion 102 and the fall prevention member 97 Starts swinging in the direction of release. Such a configuration makes it possible to delay the fluctuation of the release preventing member 97 in the release prevention direction with respect to the slide direction to the mounting position of the slide member 103. Therefore, even when the long card 91 is mounted in the insertion direction, the movement of the holding portion 99 to the release preventing position is delayed, thereby preventing the holding portion 99 from colliding with the card 91 during insertion. Thus, the card 91 can be mounted smoothly.
