Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector device mounted on a device used by inserting and removing an IC card.
In particular, the present invention relates to an eject mechanism for ejecting an inserted IC card.

[0002]

2. Description of the Related Art A connector device for an IC card is usually an IC card.
A pin header section in which a large number of pin contacts for connection to socket contacts in the card are arranged in a pin housing, a frame for guiding an IC card during insertion or removal, or an inserted IC card is detached from the pin contact. It is generally configured to include an eject mechanism for causing the pin housing and the frame to be integrally molded.

Conventionally, the eject mechanism is provided with a push rod held on the outer surface of the frame and capable of reciprocating in the IC card insertion / removal direction, and an eject lever rotatably supported by the frame or the pin housing. The one in which one end of the eject lever is engaged with a push rod is widely used. In a connector device having such an ejection mechanism,
When the push rod is pushed in while the IC card is inserted, the claw portion of the eject lever that rotates in conjunction with the push rod presses the IC card toward the near side,
The IC card can be moved in the ejection direction to a position where it can be easily removed with fingers, but since the push rod projects forward when the IC card is inserted, the push rod may be operated erroneously. There is a risk that the IC card is unexpectedly ejected due to a shock or the like. In such a case, the connection of the IC card is cut off, and a trouble such as loss of operation data occurs.

On the other hand, an IC card connector device disclosed in Japanese Utility Model Laid-Open No. 6-13072 discloses a first transmission lever and a second transmission lever for linking a push rod and a slide plate. A third transmission lever pivotally supported by the second transmission lever and capable of engaging and disengaging with the second transmission lever; and a heart-shaped cam mechanism capable of holding the push rod at a predetermined entry position and a first projection position. It is configured such that the pushing force of the push rod is selectively transmitted to the slide plate according to the protrusion amount of the push rod. That is, with the IC card inserted,
The third transmission lever is not engaged with the second transmission lever, and the push rod is held at the entry position where the push rod is pushed in a predetermined amount, but the push rod is moved to the first protruding position by the heart-shaped cam mechanism. After being protruded, if it is further pulled to the second protruding position, the third protruding position is reached at this second protruding position.
Since the transmission lever of FIG. 2 is engaged with the second transmission lever, when the push rod is pushed toward the approach position in this state,
The pushing force is transmitted to the slide plate via each transmission lever, and the slide plate presses the IC card to the near side so that the IC card can be ejected. Therefore, in this IC card connector device, the push rod is held at the entry position where the push rod does not protrude forward while the IC card is connected, and the push rod is protruded to the second protrusion position only when the IC card is ejected. Push-in operation only afterwards, IC caused by erroneous operation of push rod, etc.
It is possible to prevent a connection interruption accident of the card.

[0005]

In the IC card connector device disclosed in the above publication, the push rod can be held at a predetermined entry position while the IC card is connected, so that the push rod is erroneously operated. It is possible to prevent the connection accident of the IC card from being interrupted when the user receives a shock in the pushing direction. Also, in this IC card connector device, it is necessary to project the push rod to the second projecting position when ejecting the IC card.
If the push rod is erroneously protruded to the first protruding position irrespective of not requesting the ejection of the IC card, the push rod is not pulled to the second protruding position without pulling the push rod to the second protruding position. The push rod can be returned to the entry position again without ejecting the IC card by pushing the push rod from the front. With this configuration, an instantaneous operation error such as a case in which the push rod on the upper stage is pushed in the connector device for two IC cards and the push rod on the lower stage is pushed in is important. The ejection operation can be performed without worry.

However, such a conventional IC card connector device has three transmission levers linked between a push rod and a slide plate, and pushes the push rod in accordance with the posture of each of the transmission levers. Since the force is transmitted or interrupted to the slide plate, a large space for rotating each transmission lever is required, and there is a problem that miniaturization of the IC card connector device is hindered. Further, for such a reason, each transmission lever is inevitably arranged on the top surface or the bottom surface side of the IC card insertion slot, and in particular, a plurality of IC cards capable of inserting and removing two or more IC cards. In the case of the connector device, a plurality of sets of transmission levers must be stacked in a vertical direction while securing a sufficient space, so that there is a problem that the IC card connector device also becomes large in the height direction.

[0007]

SUMMARY OF THE INVENTION According to the present invention, the amount of pushing required to cause the push rod held at the entry position to project to the projecting position is determined after the push rod is pushed at the projecting position to reach the entering position. , The push rod must be set longer than necessary to discharge the IC card and hold the push rod at the entry position, and the push rod cannot be secured from the entry position because the former cannot be secured. A locking means for selecting a locked state is provided, and when the blocking means is in the locked state, the pushing amount of the latter is ensured.
In such an IC card connector device, when the IC card is inserted and the push rod is held at the entering position, the push rod can be protruded to the protruding position if the blocking means is locked. Since the IC card can no longer be discharged, the discharging operation of the IC card is prohibited, and the accident of disconnection can be avoided. Further, even if the blocking means is set to the locked state when the push rod is in the protruding position, the IC card can be ejected without any trouble if the push rod is pushed in, so that the operability is improved. In addition, the blocking means regulates the push rod pushed into the predetermined position so that it cannot be pushed further and releases the regulation, so that a complicated configuration and a wide space are not required.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a frame for supporting an IC card so as to be able to be inserted and withdrawn, a push rod which is held by the frame so as to be able to reciprocate and is elastically urged in the direction of discharging the IC card. An IC card having a number of pin contacts connected to socket contacts of an IC card;
In a state where the card is inserted, the push rod is moved toward the front side by the first push operation on the push rod held at the predetermined entry position and is held at the predetermined protrusion position, and In the IC card connector device wherein the push rod ejects the IC card by the second push operation with respect to the push rod at the position, and is held at the entry position, the push rod is moved from the entry position. Further, when the push rod is pushed to a predetermined restriction position on the rear side, the movement is restricted and the first push operation is prevented, and the push rod is movable to the rear side from the restriction position. A locking means for selecting between an unlocked state allowing the push operation of the first position and the second state;
When the push operation is performed, the push rod is held at the approach position without pushing the push rod to the regulation position.

With this configuration, when the IC card is inserted and the push rod is held at the approach position, the first push operation is prevented by blocking the blocking means so that the first push operation is prevented. Since the push rod cannot be protruded to the protruding position, the IC card cannot be ejected, so that an accident of disconnecting the IC card due to an erroneous operation or impact of the push rod can be prevented. Further, when ejecting the inserted IC card, the blocking means may be unlocked, the push rod held at the entry position may be pushed and protruded, and then the push rod may be pushed again. ,
Even if the blocking means is set to the locked state when the push rod is at the projecting position, the IC card can be ejected without any trouble if the push rod is pushed in. Therefore, the eject mechanism of the IC card connector device has good operability.

Further, in such a configuration, the blocking means restricts the push rod pushed into the predetermined position so that it cannot be pushed further and releases the restriction, so that a complicated configuration and a wide space are not required. Therefore, it is suitable for miniaturization of the IC card connector device. For example, if the blocking means has a slidable or rotatable lock lever, and the lock lever is extended and retracted to regulate or cancel the pushing amount of the push rod, the configuration of the blocking means can be simplified. And space saving. Further, if the lock lever is attached to the push rod, the space factor is improved. In particular, if a push lever is provided with a knob (operator) and the lock lever is incorporated in the knob, further space saving of the blocking means can be achieved. This is preferable because the lock lever can be operated easily. If such a blocking means has an elastic urging means so as to be automatically in the locked state when not operated, it is possible to more surely prevent the connection interruption accident of the IC card. It is also possible to provide the blocking means on a device such as a personal computer to which the IC card connector device is attached.

[0011] In this configuration, the transmission pin is provided with a heart-shaped cam mechanism in which the transmission pin is traceably engaged with the heart-shaped cam groove. If the rod is held at the entry position, the eject mechanism can be collectively disposed on the outer surface of the frame and the push rod, so that the IC card connector device can be further miniaturized, In particular, it is suitable when applied to an IC card connector device that supports a plurality of IC cards. Moreover, if the outlet groove of the cam groove is formed longer than the inlet groove, the push rod can be prevented from coming out of the entering position when the blocking means is in the locked state, but the push rod can be pushed in from the projecting position. For example, a desired mechanism in which the IC card can be discharged without any trouble can be easily realized.

Embodiments will be described with reference to the drawings.
FIG. 1 is a plan view showing a state in which an IC card is inserted into an IC card connector device according to an embodiment of the present invention, and FIG. 2 is a plan view showing a state in which a push rod of the connector device shown in FIG. FIG. 3 is a plan view showing an eject mechanism of the connector device shown in FIGS. 1 and 2, FIG. 4 is an exploded perspective view of the eject mechanism shown in FIG. 3, FIG. 5 is an explanatory view of a heart-shaped cam groove shown in FIG. FIG. 6 is a development view showing the cam surface of the heart-shaped cam groove shown in FIG. 5, and FIG. 7 is an operation explanatory view of the ejection mechanism shown in FIGS.

As shown in FIGS. 1 and 2, the I
The C card connector device includes a pin housing 2 in which a large number of pin contacts (both not shown) for connection to socket contacts in the IC card 1 are press-fitted and fixed in a predetermined arrangement, and , A pair of frames 3 for guiding the IC card 1 during insertion and removal from both sides in the width direction with the guide grooves 3 a, a push rod 4 attached to one of the frames 3, and a pin housing 2. It is mainly constituted by a supported eject arm 5, first and second rotating arms 6, 7, an eject mechanism interposed between the push rod 4 and the eject arm 5, and the like.

A first support shaft 8 and a second support shaft 9 are provided on the pin housing 2 at a predetermined interval, and one end of the eject arm 5 is rotated on the first support shaft 8. It is freely supported. This eject arm 5 has a connecting hole 5a.
And an engaging portion 5 b are formed, and the engaging portion 5 b protrudes to the side of the frame 3. The first rotating arm 6 is also rotatably supported on the first support shaft 8.
Are formed with a claw piece 6a for pushing out the IC card 1 and a tongue piece 6b projecting into the connection hole 5a of the eject arm 5. On the other hand, the second rotation arm 7 is rotatably supported on a second support shaft 9. The rotation arm 7 has a claw 7 a for pushing out the IC card 1 and a A tongue piece 7b projecting into the connection hole 5a is formed.

The structure of the eject mechanism will be described in detail with reference to FIGS. 3 to 6. The IC card connector device according to the present embodiment comprises upper and lower two
Although two IC cards 1 can be inserted along the guide groove 3a of the step, and two push rods 4 for ejecting both IC cards 1 are provided, the function and configuration of both push rods 4 are as follows. Since they are basically the same, one push rod 4 and its eject mechanism will be described below (FIG. 4 also shows only one push rod).

The push rod 4 has a knob (operator) 4a at a front end thereof. The push rod 4 is formed by a projection 3b or the like provided on the outer surface of the frame 3 and engaged with the knob 4a. Reference numeral 4 is held so as to be able to reciprocate along the insertion / removal direction of the IC card 1 (the directions indicated by arrows A and B in FIG. 3). Further, inside the knob 4a, a blocking means for restricting the push rod 4 pushed to a predetermined position so as not to be pushed further and releasing the regulation is provided. This blocking means is always elastically biased in the direction of arrow C in FIG. 3 by a spring member (not shown).
The lock lever 16 has a character-shaped lock lever 16 incorporated in the knob 4a. One end (front end) 16a of the lock lever 16 is exposed to the front of the knob 4a, and the other end (side end) 16b. Protrudes toward one side of the knob 4a (in the direction of arrow C), and the side end 16b can be housed in the knob 4a by sliding the lock lever 16 in the direction of arrow d in FIG. The push rod 4 is constantly urged by the coil spring 10 in the IC card ejection direction (the direction of the arrow B in FIG. 3), but the stopper piece 4b formed on the push rod 4 is fixed to the frame 3. The push rod 4 does not protrude beyond the predetermined protruding position shown in FIGS. 2 and 3 because the movement in the same direction is restricted when the mounting rod 11 comes into contact with the mounting bracket 11. The other end of the transmission pin 12 having an L-shaped operating portion 12a at its tip is pivotally supported by the hole 4c of the push rod 4 so as to be swingable, and a leaf spring 13 attached to the push rod 4 is provided. Always biases the transmission pin 12 toward the outer surface of the frame 3.

On the outer surface of the frame 3, a heart-shaped cam groove 14 is formed.
2a is engaged with this cam groove 14. As shown in FIGS. 5 and 6, the cam groove 14 has a plurality of cam surfaces A having different heights.
, And the operating portion 12a of the transmission pin 12 traces these cam surfaces A to E in the direction of the arrow in FIG. However, the operating portion 12a is provided on the frame 3 by the leaf spring 13.
The operating portion 12a can be moved smoothly without falling off from the cam groove 14, and reliable tracing can be performed. Further, since the push rod 4 that supports the transmission pin 12 is constantly urged rightward in FIG. 5 by the coil spring 10, the operating portion 12 a is positioned on the cam surface B of the cam groove 14 at the right end in the figure. Will be locked. The cam groove 14 has an outlet-side groove that allows the operating portion 12a to escape from the locking portion on the cam surface B, and an inlet-side groove that guides the operating portion 12a to the locking portion. It is longer than the groove.

A driving plate 15 is held outside the frame 3 so as to be able to reciprocate in the direction in which the IC card 1 is inserted and withdrawn. Is inserted into a long groove 3c engraved on the outer side surface. The long groove 3c and the cam surface D of the cam groove 14 are linearly continuous, and the receiving portion 15a of the driving plate 15 reciprocates along the long groove 3c and the cam surface D. Further, an engagement hole 15b is formed in the drive plate 15, and this engagement hole 15b is engaged with the engagement portion 5b of the eject arm 5.
Are engaged outside the frame 3.

In the IC card connector device configured as described above, when the IC card 1 is not inserted, the push rod 4 is held at the entry position where the push rod 4 has entered a predetermined amount in the pushing direction. In this state, as shown in FIG. 7A, the operating portion 12a of the transmission pin 12
Are locked on the cam surface B of the cam groove 14, and the push rod 4 is stably held at the entry position by the tensile force of the coil spring 10 and the transmission pin 12 locked in the cam groove 14. I have.

When the IC card 1 is inserted along the guide groove 3 a of the frame 3, the IC card 1 heading for the pin housing 2 is moved to the first and second pivot arms 6.
7, the pin contacts of the pin housing 2 are pressed into their own socket contacts while pushing the claw pieces 6a, 7a. By inserting the IC card 1 by a predetermined amount, the IC card 1 is securely connected to each pin contact. (See FIG. 1). At this time, the first rotation arm 6 and the second rotation arm 7 rotate in opposite directions about the first support shaft 8 and the second support shaft 9, respectively. , 7 are rotated by tongue pieces 6b, 7b
To the eject arm 5, the eject arm 5 rotates about the first support shaft 8 as a rotation axis, and the driving plate 15 moves forward along the frame 3 in conjunction with the rotation. As a result, as shown in FIG. 7B, the receiving portion 15a of the driving plate 15 moves from the long groove 3c to the cam groove 14c.
However, at this time, since the operating portion 12a of the transmission pin 12 is locked on the cam surface B, even if the receiving portion 15a enters the cam groove 14, the operating portion 12a moves to the operating portion 12a. Does not abut. That is, while the IC card 1 is connected, the push rod 4 is maintained in the state of being held at the entry position.

If the IC card 1 inserted in this manner is erroneously ejected, trouble such as loss of operation data may be caused. However, the side end 16b of the lock lever 16 is connected to the front end face of the frame 3 and the knob 4a. 7C, the operating portion 12a of the transmission pin 12 cannot escape from the cam surface B even if the push rod 4 is pushed further inward from the entry position as shown in FIG. 7C. . In other words, when the side end portion 16b of the lock lever 16 is protruding, the push rod 4 can be pushed in further to the restriction position farther than the entry position, but cannot be moved further back. Specifically, as shown in FIG. 7 (c), when the pushing amount of the push rod 4 required to move from the entry position to the restriction position is S, the operating portion 12a is locked on the cam surface B. The pushing amount S1 of the push rod 4 which is required at least to escape from the position is set to be longer than S. Therefore, even if the push rod 4 held at the entry position is erroneously pushed in or the impact in the pushing direction is applied to the knob 4a, the push rod 4 does not move beyond the regulation position, and therefore the push rod 4 does not move. 4 automatically returns to the entry position without performing the discharging operation of the IC card 1, and the connection state of the IC card 1 is maintained.

When the IC card 1 in the inserted state is ejected from the connector device, first, the front end 16a of the lock lever 16 exposed on the front side of the knob 4a of the push rod 4 is moved to the position shown in FIG. The user slides in the direction of arrow D to store the side end 16b in the knob 4a, and then pushes the knob 4a in the direction of arrow A in FIG. Then, as shown in FIG. 7D, the operating portion 12a of the transmission pin 12 escapes from the cam surface B of the cam groove 14 and moves to the cam surface A, and the coil spring 1
As a result of the transition from the cam surface A to the cam surface D via the cam surface E by a pulling force of 0, as shown in FIG.
The push rod 4 moves toward this side (in the direction of arrow B in FIG. 3) and projects to a predetermined projecting position. Also in this process, the operating portion 12a of the transmission pin 12 does not come into contact with the receiving portion 15a of the drive plate 15, and therefore, when the push rod 4 moves to the protruding position, the operating portion 12a is brought into contact with the receiving portion 15a within the cam surface D. You will face each other.

After the push rod 4 is protruded to the protruding position in this way, the knob 4a of the push rod 4 is pushed again in the direction of arrow A in FIG. 3 (second push operation).
As shown in FIGS. 7F and 7G, the operating portion 12a of the transmission pin 12 shifts from the cam surface D of the cam groove 14 to the cam surface B via the cam surface C. At the time of the pushing operation, it is not necessary to slide the lock lever 16 in order to store the side end portion 16b in the knob 4a.
That is, the push rod 4 extends from the projecting position to the approach position.
At the stage when the push rod 4 is pushed in, the further pushing amount S2 of the push rod 4 which is the minimum necessary to guide the operating portion 12a of the transmission pin 12 to the cam surface B and lock it is required to move the push rod 4 from the entry position to the regulation position. 7 is set shorter than the push-in amount S of the push rod 4 necessary for the push rod 4, even if the push rod 4 can be pushed only to the restricted position in the locked state in which the side end portion 16b of the lock lever 16 is protruded, FIG. As shown in (g), the operating portion 12a is reliably guided from the cam surface C to the cam surface B, and the push rod 4 is again held at the approach position as shown in (a) of FIG. In the process in which the operating portion 12a of the transmission pin 12 moves on the cam surface D with the pushing operation, the operating portion 1
2a abuts against and presses against the receiving portion 15a of the drive plate 15, so that the eject arm 5 engaged with the drive plate 15 rotates, and the first and second rotating arms are interlocked with this rotation. 6, 7a and 7a press the front ends of the IC card 1 almost straight in the detaching direction, and as shown by a two-dot chain line in FIG. The press-fit state of the contact is released. Therefore, in this state, the IC card 1 can be easily ejected from the connector device by grasping the front side of the IC card 1 with fingers and pulling it out.

In the above embodiment, the lock lever 16 is always urged in the direction of arrow C in FIG. 3 so that the lock means is set to the locked state when not operated.
It is also possible to employ blocking means for manually switching between the locked state and the unlocked state. However,
In the case of manual operation, it is conceivable to forget to set the lock state. Therefore, in order to surely avoid the accident of disconnection of the IC card, it is preferable to use the blocking means that automatically locks when not operated.

FIG. 8 is an explanatory view showing a blocking means according to another embodiment of the present invention. The lock lever 16 incorporated in the knob 4a of the push rod 4 rotates around the support shaft 17 in the directions of arrows E and F. And the spring member 18 constantly resiliently biases the lock lever 16 in the direction of the arrow, so that the side end 16b of the lock lever 16 is not operated when it is not operated.
Is set in a locked state in which the knob 4a projects to one side of the knob 4a so that the knob 4a can be pushed only to a predetermined regulating position. When the IC card needs to be pushed farther than the regulating position, the knob 4a is unlocked by rotating the lock lever 16 in the direction of arrow E against the resilience of the spring member 18 when ejecting the IC card. Push the knob 4a in the locked state.

In the above embodiment, a connector device into which two IC cards can be inserted has been described as an example. However, the present invention is applied to a connector device into which one or three or more IC cards can be inserted. Can be similarly applied.

[0027]

The present invention is embodied in the form described above and has the following effects.

When the push rod is held at the approach position, the blocking means is set in a locked state,
The push rod, which cannot be pushed in by the required amount, cannot be protruded to the protruding position, so that the IC card cannot be ejected. Therefore, it is possible to prevent a connection interruption accident of the IC card due to an erroneous operation or impact of the push rod. . Further, when ejecting the inserted IC card, the blocking means may be unlocked, the push rod held at the entry position may be pushed and protruded, and then the push rod may be pushed again. Even if the blocking means is set to the locked state when the push rod is in the protruding position, the IC card can be ejected without any trouble if the push rod is pushed in. Therefore, the eject mechanism of the IC card connector device has good operability.

In addition, the blocking means regulates the push rod pushed into the predetermined position so that it cannot be pushed any further, or cancels the regulation.

For example, if the blocking means has a slidable or rotatable lock lever, and the lock lever is extended and retracted to regulate or cancel the pushing amount of the push rod, the configuration of the blocking means can be simplified. And space saving.
Further, if the lock lever is attached to the push rod, the space factor is improved. In particular, if a push lever is provided with a knob (operator) and the lock lever is incorporated in the knob, further space saving of the blocking means can be achieved. This is preferable because the lock lever can be operated easily. If such a blocking means has an elastic urging means so as to be automatically in the locked state when not operated, it is possible to more surely prevent the connection interruption accident of the IC card.

Also, a heart-shaped cam mechanism having a transmission pin traceably engaged with the heart-shaped cam groove is provided, and the transmission rod is locked at a predetermined position of the cam groove so that the push rod can enter the heart-shaped cam groove. If it is held at the position, the eject mechanism can be collectively arranged on the outer surface of the frame and the push rod, so that the IC card connector device can be further downsized, and particularly, a plurality of IC card connectors can be supported. It is suitable when applied to the IC card connector device. In addition, if the exit groove of the cam groove is formed longer than the entrance groove, the push rod can be prevented from coming out of the entrance position when the blocking means is in the locked state, but the push rod can be pushed in from the projecting position. For example, a desired mechanism in which the IC card can be discharged without any trouble can be easily realized.
