As shown in FIG.

FIG. 6 is a perspective view showing the card 50, the slide member 4, and the locking mechanism 6 in a state where the card 50 is locked. As shown in this figure, the cam lever 7 engages with the 1st leg part 31 inserted in the cam groove 9 from the side. Moreover, in the locked state of the card 50, the cam lever 7 is caught by the locking part 23a formed in the cam groove structure part 23, and is hold | maintained so that the slide member 4 may not slide.

Fig. 7 shows a plan view of the card connector with the cover body 2 removed in the state where the card 50 can be taken out. As shown in this figure, in the state where the card 50 can be taken out, the card 50 is located at a position slid outward from the card storage portion 11 than in the state shown in FIG. The state of the card 50 is slid to the discharge side.

In this state, the slide member 4 is engaged with the recessed portion 51 of the card 50 while the latching portion 21 is engaged with the pressing portion 21 formed on the side opposite to the latching portion 21. 22 is elastically supported by the slide elastic support member 8 toward two directions of the recessed part 51 side direction of the card 50, and a card insertion direction.

The slide elastic support member 8 is folded in a substantially U shape from the side abutting portion 40 and the side abutting portion 40, which abuts against the inner circumferential surface of the housing 1, and is inclined toward the slide member 4 side. It consists of the spring part 41 extended in a shape, and the front-end | tip part of the spring part 41 is further bent, and is formed as the step part 42 which has the inclined surface part 42a and the front-end surface part 42b.

On the other hand, the press part 22 of the slide member 4 is formed in the shape suitable for the step part 42 of the slide elastic support member 8 substantially. Thereby, when the slide member 4 slides to the ejectable position of the card 50, the press part 22 is pressed by the step part 42 of the slide elastic support member 8, and is shown by the arrow of FIG. It is in the state pressed in the direction. This pressing force has the component force of two directions of the recessed part 51 side of the card 50, and a card insertion direction, and the slide member 4 will be in the state elastically supported toward the said two directions.

Moreover, the stopper part 15 which protrudes inward is formed in the inner peripheral surface of the housing | casing 1 in the vicinity of the bending part of the slide elastic support member 8, and the slide member 4 opposes the stopper part 15; The contact surface 24 is formed so that it may become. In the position where the slide member 4 is pressed against the slide elastic support member 8, the slide member 4 is not in contact with the stopper portion 15 but is in a spaced apart state. That is, when the slide member 4 slides by the elastic support member 5 and moves to the position which can eject the card 50, the slide member 4 will contact the slide elastic support member 8, Only the slide operation is stopped.

Thus, when the slide member 4 and the slide elastic support member 8 are comprised, when the slide member 4 slides to a discharge direction by the elastic support of the elastic support member 5, the slide member 4 will contact | abut. Before the surface 24 abuts the stopper portion 15 of the inner circumferential surface of the housing 1, the pressing portion 22 of the slide member 4 abuts against the slide elastic support member 8, whereby the slide operation is performed. In addition to being stopped, the slide member 4 is elastically supported by the slide elastic support member 8 not only in the recess 51 side of the card 50 but also in the insertion direction of the card 50. Therefore, the impact accompanying the sudden stop of the slide member 4 slid smoothly by the elastic support force of the elastic support member 5 is alleviated by the slide elastic support member 8, so that the slide of the card 50 Protruding from the housing 1 as it is without stopping can be prevented.

Next, the operation of the locking mechanism 6 in ejecting and inserting the card 50 will be described. When the card 50 is pressurized from the locked state shown in FIG. 2 to the deepest part of the housing 1 further, the lock by the locking mechanism 6 is released, and the slide member 4 slides in the discharge direction. With this, the card 50 slides in the discharge direction. When the card 50 slides to the dischargeable position, as shown in FIG. 7, the slide member 4 is stopped by the slide elastic support member 8, and the slide of the card 50 also stops. By further pulling the card 50 out of this state, the engagement state between the slide member 4 and the card 50 is released, and the card 50 can be taken out of the housing 1.

At the time of insertion of the card 50, the slide member 4 slides inside the housing 1 with the insertion of the card 50, and the card 50 is inserted to the deepest part of the housing 1 by hand. , The cam lever 7 of the locking mechanism 6 is caught by the locking portion 23a of the cam groove 9, and the card 50 is also locked as the slide member 4 is locked. . These processes will be described below.

8, the side sectional drawing in the state in which the card 50 was locked is shown. As also shown in FIG. 6, in the state in which the card 50 is locked, the cam lever 7 is caught by the locking part 23a formed in the cam groove structure part 23 of the slide member 4. As shown in FIG. Moreover, in the cover body 2, the press piece 2b bent in the substantially L shape toward the downward direction in the vicinity of the insertion direction edge part of the card 50 is formed, and the 2nd leg part 32 of the cam lever 7 ) Is pressed downward from above. As a result, the cam lever 7 can freely swing the base 30 and the first leg 31 in the vertical direction.

The cam groove constitution portion 23 of the slide member 4 has a diameter of the first leg portion 31 of the cam lever 7 in the portion of the guide portion 23b at the time of insertion and the guide portion 23c at the time of discharge. It is formed so that it may become narrower. In the state of FIG. 8, a slight gap is formed between the upper surface of the slide member 4 and the lower surface of the cover body 2, and the cam groove 9 is formed in the portion of the guide portion 23c at the time of discharge. The distance between the side wall on the slide member 4 side and the side wall on the cover body 2 side is such that the width is approximately equal to the diameter of the first leg portion 31 of the cam lever 7.

9, the side sectional drawing in the state in which the card 50 was pushed to the deepest part at the time of ejection of the card 50 is shown. As shown in this figure, when the card 50 is pushed by hand from the locked state to the deepest part, the slide member 4 slides inside the housing 1 with it, and the cam lever 7 is locked. The locked state in the part 23a is canceled and the inside of the cam groove 9 slides upward. When the hand which pushes in the card 50 in this state is released, the slide member 4 with which the latch by the cam lever 7 was canceled is discharged direction of the card 50 by the elastic support force of the elastic support member 5. Slides to. In association with this, the card 50 is also slid in the discharge direction.

When the slide member 4 slides in the discharge direction of the card 50, the cam lever 7 slides the cam groove 9 through the upper path from the state of FIG. 9. Here, since the step part 23e in which the locking part 23a side becomes high is formed in the locking part 23a side of the cam groove structure part 23, the cam lever 7 is certain It can slide through the upper path | route of the cam groove 9 similarly. In addition, as described above, when the cam lever 7 is in the locking portion 23a or the upper path, the gap is between the upper surface of the slide member 4 and the lower surface of the cover body 2. Since the width is substantially equal to the diameter of the first leg portion 31 of the cam lever 7, it can slide smoothly.

10 is a side cross-sectional view in a state where the card 50 can be taken out. This figure corresponds to the top view state shown in FIG. As shown in FIG. 10, when the slide member 4 slides from the state of FIG. 9 in the discharge direction of the card 50, the cam lever 7 passes through the path above the cam groove 9 and further guides. It passes through the part 23d part and reaches near the edge part. As described above, the slide member 4 is stopped by the slide elastic support member 8, and the slide member 4 is in a state in which the card 50 can be taken out.

11, the top view of the connector for cards which removed the cover body 2 in the state which removed the card 50 from the state shown in FIG. 7 is shown. As shown in this figure, when the card 50 is taken out by hand from the state shown in FIG. 7, the engagement state of the engagement part 21 of the recessed part 51 of the card 50 and the slide member 4 is It releases and the card 50 slides in the state which pressed the slide member 4 and the slide elastic support member 8 to the inner peripheral surface side of the housing 1 by the side surface of the card 50. Although the slide member 4 slides slightly with the card 50 being taken out, the contact surface 24 abuts against the stopper part 15 of the housing 1, and the slide member 4 does not slide further to the discharge side. Do not.

In FIG. 12, the side sectional drawing in the state of FIG. 11 is shown. As shown in this figure, as the slide member 4 slides slightly toward the discharge side with the card 50 being taken out, the cam lever 7 slides to the end of the guide portion 23d.

In FIG. 13, the side sectional drawing in the state which pushed the card 50 to the deepest part at the time of inserting the card 50 is shown. As shown in this figure, when the card 50 is pushed into the card storage part 11, the slide member 4 slides inside the housing 1 inward with it, and the cam lever 7 cams The groove 9 is slid through the lower path from the guide portion 23d and the card 50 is pushed to the deepest portion to reach the end. At this time, as shown in FIG. 5, between the guide part 23d and the discharge | release guide part 23c so that the cam lever 7 may reliably slide from the guide part 23d to the guide part 23b side at the time of insertion, A stepped portion 23f is formed in which the guide portion 23c side becomes higher during discharge.

Moreover, when the cam lever 7 slides the path | route below the cam groove 9, since the slide member 4 is pushed up by the cam lever 7, the lower surface of the slide member 4 and the housing 1 A gap is formed between the bottoms of the backplanes. Thereby, the clearance of the diameter part of the 1st leg part 31 of the cam lever 7 is ensured between the side wall of the slide member 4 which comprises the cam groove 9, and the side wall of the housing 1 side. .

When the card 50 is pushed to the deepest part and released, the slide member 4 slides in the discharge direction of the card 50 by the elastic support force of the elastic support member 5, as shown in FIG. Since the slide member 4 is provided with a stepped portion 23g in which the guide portion 23b side becomes higher than the position where the cam lever 7 is engaged in the most pushed-in state, the cam lever 7 is formed. It does not return to the guide part 23b side at the time of insertion, but slides to the locking part 23a side, and it catches on this and locks the slide member 4. This returns to the state of FIG. 2 and FIG. 8 again.

In this way, the cam groove 9 is constituted by the cam groove constitution portion 23 of the slide member 4, the bottom surface of the housing 1, and the lower surface of the cover body 2, thereby forming the slide member 4. Since it is not necessary to form all the side walls in the side wall), the slide member 4 can be made thin, whereby the body portion composed of the housing 1 and the cover body 2 can be made thinner.

Moreover, the width of the cam groove constitution part 23 of the slide member 4 is formed smaller than the diameter of the 1st leg part 31 of the cam lever 7, and the cam lever 7 passes along the path | route. By configuring the width of the cam groove 9 to be changed, the slide member 4 can be made thinner and the thickness can be further reduced.
