2. Description of the Related Art Conventionally, a card connector has been provided with an eject mechanism for removing an inserted card. The eject mechanism usually includes an actuator member that engages with the card, and an eject lever connected to the actuator member. The eject lever is provided so as to be movable in the card insertion / removal direction (for example, the See JP-A-5-8675. The eject lever extends to a side position of the card insertion slot,
A push button for eject operation was directly provided at the end. In the card connector having such a structure, when the card is removed, the push button is pushed down to a position substantially flush with the card insertion slot.
When the card was inserted, the push button protruded outward from the card slot.

A push button provided at the end of the eject lever is constructed so that it can be folded at an intermediate portion. When a card is inserted, the push button is folded so that the push button is outside the insertion slot of the card. Some things were known so that they could not protrude. In this case, when the card is inserted, it is necessary to fold the push button protruding outward, and when removing the card, it is necessary to return the folded push button to the original position before performing the eject operation. .

[0004]

As described above, the eject lever of the eject mechanism provided in the conventional card connector has a problem that the eject lever protrudes outward from the card insertion slot and becomes obstructive. In addition, if the push button can be folded, it will be necessary to perform the operation of folding and restoring it, which will complicate the operation of inserting and removing the card, and will have space for accommodating the folded part of the push button. This necessitates a problem that the space efficiency of the device is deteriorated.

The present invention has been made in view of such a problem, and a push button provided for operating an eject mechanism of a card connector can always be pushed in the card insertion direction and project outward. An object of the present invention is to provide a coupling mechanism attached to an eject lever of a card connector, which can improve the space efficiency of the device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a cam plate 1 according to a first embodiment,
The relation and operation of the push button 2 and the eject lever 3 are shown. As shown schematically in FIG. 2, the eject lever 3 is provided on the side of the case 5 constituting the card connector 4 and moves the eject lever 3 when removing the inserted card from the card insertion slot 6. The card is pushed in the card insertion direction shown in FIG. On the other hand, the cam plate 1 is provided beside the eject lever 3 and is operated via the push button 2. The card insertion direction indicated by arrow 7 or the card removal direction opposite thereto is herein referred to as the card insertion direction X. Also, the guide frame is perpendicular to the
A direction parallel to the upper surface 8A of the memory 8 is defined as an orthogonal direction Y. The cam plate 1 is supported by a guide frame 8 provided integrally with the case 5 so as to be movable in a card insertion / removal direction X and an orthogonal direction Y, and is removed by a spring member 9 in a direction opposite to the arrow 7. Biased in the direction. The push button 2 is provided so as to be movable in the direction of insertion / extraction X through the guide frame 8 and engages with the long groove 10 formed in the cam plate 1 along the orthogonal direction Y to push the cam plate 1 in the insertion / extraction direction X. The button 2 is moved integrally. In the orthogonal direction Y, the cam plate 1 can move independently of the push button 2.

On the cam plate 1, two heart cams 11, which will be described in detail below, are formed side by side. And
Pin members 13 having pins 12 at both ends for engaging with the respective heart cams 11 are installed via support brackets 14 installed so as to cover the cam plate 1.
The pins 12 are urged toward the heart cam 11 by the leaf springs 15 provided on the pin 4. An opposing portion 16 is formed on the side edge of one end of the cam plate 1 so as to protrude in the orthogonal direction Y. When the cam plate 1 moves on the upper surface 8A of the guide frame 8 in the orthogonal direction Y, the ejection is performed. The lever 3 can be engaged with the lever 3. The heart cam 11
Are formed in a plane on the other end side of the facing portion 16.

Heart cam 11 formed on cam plate 1
Has the structure shown in FIG. 3 and FIG. That is, the cam grooves F, G, and H for projecting the push button 2 in the card removal direction, the cam groove L for pushing the eject lever 3 in the card insertion direction, and the push button 2 independent of the eject lever 3. Then, the cam grooves A, B, and C for pushing in the card insertion direction are formed substantially in parallel, and these are connected by oblique cam grooves D, E, K, and the like. A part of the cam grooves A and L are also skewed cam grooves a and l, so as to form a closed cam groove as a whole. Each cam groove A, B, C, F, G, H, L and skew cam groove D, E,
K is formed at a depth as shown in FIG. 4, and the leaf spring 15 urges the pin 12 in this depth direction. It is going to go. The cam grooves B and G have inclined bottoms, and have varying depths.

The operation of the connecting mechanism of the embodiment will be described with the state in which a card is inserted into the card connector 4 as an initial state. This initial state is as shown in FIG. 1, in which the push button 2 is pushed in the card insertion direction and the pin 1
2 is engaged with the skew cam groove E of the heart cam 11. When the push button 2 is slightly pushed in the card insertion / removal direction X, the cam plate 1 slightly moves to the eject lever 3 side in the orthogonal direction Y due to the oblique cam groove E. The pin 12 comes into engagement with the cam groove F. Here, when the force pressing down the push button 2 is removed, the cam plate 1 is urged by the spring member 9 and the pin 12 is movable along the cam grooves F, G, H. Then, the cam plate 1 and the push button 2 are pushed out in the direction X of insertion and removal with respect to the pin 12 provided fixedly. Pin 12 is skewed cam groove K
Engage when depressed.

Next, when the pushed push button 2 is pushed in, the cam plate 1 further moves toward the eject lever 3 in the orthogonal direction Y due to the oblique cam groove K, and the pin 1
2 falls into the cam groove L, and is in the state shown in FIG. When the distance between the skew cam groove E and the cam groove L moves in the orthogonal direction Y of the cam plate 1, the opposing portion 16 is just opposite to the eject lever 3 so as to be engageable. .
Then, when the push button 2 is further pushed in the direction of insertion / extraction X, the eject lever 3 is pushed through the cam plate 1, and the card inserted into the card connector 4 is ejected. The state where the ejection is completed by pushing the push button 2 is in the state of, and the pin 12 is engaged with the end of the cam groove L. The cam groove L has a length substantially equal to the stroke required for ejecting the card by the eject lever 3. When the force for pushing the push button 2 is released, the cam plate 1 urged by the spring member 9 is pushed out in the insertion / extraction direction X, and the push button 2 is in a projected state. The pin 12 moves from the cam groove L to the cam groove A, and is engaged with an end of the oblique cam groove a which forms a part of the cam groove A. Due to the oblique cam groove 1 that forms a part of the cam groove L, the cam plate 1 moves in a direction away from the eject lever 3 in the orthogonal direction Y, and
Can not be engaged with the eject lever 3.

Here, the push button 2 is pressed again.
Since the pin 12 is engaged with a part of the oblique cam groove a of the cam groove A, the cam plate 1 moves in the insertion / removal direction X while moving further away from the eject lever 3. Since it does not engage with the eject lever 3, only the cam plate 1 moves. This is the situation. The pin 12 will engage with the oblique cam groove D. When the pressing force of the push button 2 is released, since the cam plate 1 is urged by the spring member 9, as shown in the right end of FIG.
The push button 2 is slightly pushed out. Pin 12 moves from the engagement of the oblique cam grooves D the engagement of the oblique cam grooves E, initial
State .

In the above description, it is assumed that another card is inserted into the card connector 4 following the completion of the ejection of the card. When the card is inserted, the eject lever 3 is pushed out in the insertion / extraction direction X (shown in a pushed-out state in FIG. 1), but at this time, the opposing portion 16 of the cam plate 1 and the eject lever 3 are not engaged. It has become. Therefore, when the push button 2 is pushed in as in the above, the cam plate 1 is pushed in the insertion / extraction direction X independently of the eject lever 3, and even if a card is inserted, the push button 2 is pushed outward. Can not be projected. The distance between the cam groove L and the cam grooves A, B, C is wider than the length of the facing portion 16 protruding in the orthogonal direction Y.

The depth of each of the cam grooves A, B, C, F, G, H, L and the oblique cam grooves D, E, K is changed as shown in FIG. The main purpose is to accurately shift the engagement between the pin 12 and the cam groove or the oblique cam groove. However, when the pin 12 shifts to a deeper groove, a "click" sound is generated. The purpose is to acoustically inform the operator that this connection mechanism is functioning properly. Therefore, when the click sound is not particularly required, the depth of the groove may not be changed. For example, the depth of the cam groove F is
It is as simple as having the same depth as.

FIGS. 5 and 6 show a heart cam 17 formed on the cam plate 1 of the second embodiment. The heart cam 17 has cam grooves F and G for projecting the push button 2 in the card removal direction and cam grooves B and C for pushing the eject lever 3 in the card insertion direction. Are communicated by oblique cam grooves A, D, and E. The depth of each groove is as shown in FIG. The skew cam groove A has a straight cam groove a1 for connecting to the cam groove B and a straight cam groove a2 and a3 for connecting to the cam groove F, all of which have the same depth. Therefore, they are handled as one skewing cam groove A. A part of the cam groove G includes a skew cam groove g for connecting to the skew cam groove A, and a part of the skew cam groove D includes a straight cam groove d. Have been. Also in these cases, the depths of the straight portion and the oblique portion are the same.

In the initial state in which the card is inserted into the card connector 4, the push button 2 is at the position where it is pushed in the insertion / extraction direction X, and the pin 12 is engaged with the oblique cam groove E. The operation will be described as follows.
First, when the push button 2 is slightly depressed (leftward in FIG. 5), the cam plate 1 is also depressed and moves away from the eject lever 3 in the orthogonal direction Y due to the oblique cam groove E (upward in FIG. 5). Go to). The engagement of the pin 12 moves from the skew cam groove E to the straight cam groove a3 of the skew cam groove A. When the force for pushing the push button 2 is removed, the spring member 9
The cam plate 1 and the push button 2 receiving the urging force are pushed out in the card removal direction (rightward in FIG. 5). Then, the pin 12 passes through the cam grooves F and G and moves to the straight cam groove a2 of the oblique cam groove A. Due to the oblique cam groove g formed in a part of the cam groove G, the cam plate 1 moves toward the eject lever 3 in the orthogonal direction Y (downward in FIG. 5).
, But the facing portion 16 provided on the cam plate 1
Is a position where it cannot be engaged with the eject lever 3 yet.

Next, the push button 2 pushed out is pushed in. Since the pin 12 is engaged with the skewed cam groove A, the cam plate 1 is provided with the straight cam groove a2 of the skewed cam groove A.
And the orthogonal cam groove a1 is moved toward the eject lever 3 (downward in FIG. 5) in the orthogonal direction Y. This moving distance is set to a distance at which the facing portion 16 can be engaged with the eject lever 3. Since the pin 12 can move from the straight cam groove a1 of the skew cam groove a to the cam grooves B and C and further to the straight cam groove d of the skew cam groove D,
By keeping the push button 2 pressed, the eject lever 3
Is pushed in the card insertion / removal direction X, and the card is ejected. The pin 12 engages with the straight cam groove d of the oblique cam groove D.

When the pressing force of the push button 2 is released after the card is ejected, the cam plate 1 is pushed back by the urging force of the spring member 9 and returned in the direction of the insertion / extraction direction X (rightward in FIG. 5). . At this point, pin 12
Is engaged with the skewed cam groove D, the cam plate 1 moves in a direction away from the eject lever 3 in the orthogonal direction Y (upward in FIG. 5) while returning, and eventually the pin 1
2 stops when it engages with the oblique cam groove E, and the initial state is established. The cam plate 1 is separated from the eject lever 3, and the facing portion 16 is at a position where it cannot be engaged with the eject lever 3. Therefore, even if another card is mounted, the cam plate 1 and the push button 2 do not move, and the pressed state of the push button 2 can be maintained as it is.

In the second embodiment, since the heart cam 17 is constituted by two substantially parallel cam grooves and a skewed cam groove, the heart cam 11 is formed by three substantially parallel cam grooves and a skewed cam groove. Compared to the first embodiment, the width of the cam plate 1 can be reduced, and this has the advantage of contributing to downsizing of the coupling mechanism and, consequently, the entire card connector 4. Further, when the push button 2 is protruding, it means that the card is always ejected when the button is pushed. There are cases where the card is ejected and cases where only the push button 2 is pushed without ejecting the card. There is an advantage of ease of use as compared with the first embodiment.

In each of the embodiments, two heart cams 11 and 17 are formed side by side on the cam plate 1. This is achieved by engaging the pins 12 with the respective heart cams.
This is to prevent the cam plate 1 from rotating. Therefore, the heart plate 11 and 17 can be united by providing another rotation preventing mechanism, for example, a mechanism such as engagement between a guide groove and a ridge on the cam plate 1. Combining the heart cams 11 and 17 allows the cam plate 1 to be downsized, but requires a space for a rotation preventing mechanism. This is determined in consideration of the space allowed for the connecting mechanism provided in the card connector 4. Also, the cam plates 1, 1
The biasing force of the spring member 7 in the insertion / extraction direction X is limited to a structure in which the spring member 9 is engaged with the cam plate 1 and the repulsive force of the spring member 9 is directly applied to the cam plate 1 as shown in FIG. is not. For example, the cam plate 1 can be indirectly biased by applying a tensile force or a repulsive force of the spring member to the push button 2.

X between the cam plates 1 and 17 and the pin 12
Movement in the Y direction is relative. In the embodiment described above, the pin 12 is set at the fixed position, and the cam plate 1 can be moved in the insertion / extraction direction X and in the direction Y orthogonal to the insertion / extraction direction X and parallel to the upper surface 8A of the guide frame 8. However, as in the third embodiment shown in FIG. 7 and subsequent figures, the cam plate 18 is installed at a fixed position, and the pins 19 are inserted into and removed from the cam plate 18 in the inserting and removing directions X and the inserting and removing directions. It can also be movable in a perpendicular direction Y perpendicular to X and parallel to the side wall 22A of the slider 22.

In the third embodiment, the cam plate 18 is mounted on a mounting plate 20 which is mounted along an eject lever of a card connector (not shown) via a gate-shaped cover 21 in a fixed position. The slider 22 is installed along the cam plate 18 so as to be movable in the insertion / extraction direction X. Slider 22
Constitutes the push button 23. This slider 2
2, the pin plate 25 is inserted into the plate accommodation groove 24 formed on the surface facing the cam plate 18 in the insertion and removal direction X.
The same heart cam as in each of the above-described embodiments in which a pin 19 is mounted on the cam plate 18 so as to be movable in a direction Y orthogonal to the side wall 22A of the slider 22 and protruding from the surface of the pin plate 25. In the cam groove 18a. The slider 22 is biased in the card removal direction (rightward in FIG. 7) along the insertion / extraction direction X by extending a spring member 28 between the dowel 26 at the tip and the hook 27 of the cover 21. I have. Further, the cam plate 18 is urged toward the slider 22 by a cantilever spring piece 29 formed by punching the side wall of the cover 21, and as a result, the pin 19 is urged toward the cam plate 18. An opposing portion 30 is formed at one end side edge of the pin plate 25 so as to protrude in the orthogonal direction Y. The end portion of the eject lever of the card connector is inserted through the opening 31 of the mounting plate 20 in the insertion / removal direction. It is made to be able to oppose with X.

The cam plate 1 according to the third embodiment
Also in the relationship between the pin 8 and the pin 19, the opposing portion 30 and the eject lever of the card connector are controlled so as to face each other and not to face each other, and the push button 23 is protruded to the outside when necessary for ejecting the card. At other times, it can be pushed into a position along the card connector.
