The coil spring with a strong force, and the elastic holding piece supported on the above-mentioned sliding member in a cantilever shape. When the card is inserted, the elastic holding piece is fitted into the notch of the side edge of the card from the side to stably hold the card at the mounting position in the case (for example, refer to Patent Document 1). In addition, while the heart-shaped cam groove is formed on the slide member, a movable pin member is supported on the housing so as to be swingable along the heart-shaped cam groove, and the pin member is locked to the locking portion of the heart-shaped cam groove, thereby Lock the sliding parts in place.

In the conventional card connecting device generally constructed as above, if the card is inserted from the card insertion port of the case and pushed inwardly, the elastic holding piece held on the slide member abuts against the side portion of the card and is pushed outwardly. After the elastic deformation occurs, the card is held by the slide member via the elastic holding piece by fitting the side edge of the card from the side. At this time, although the sliding member stops, if the card is further pushed inward, the sliding member resists the elastic force of the coil spring and moves toward the device by the pressing force, and as this action proceeds, the pin member slides along the The heart-shaped cam groove of the part slides. Moreover, since the pin member can be locked in the locking portion of the heart-shaped cam groove by inserting the card by a certain amount in the housing, the slide member is locked, and the card becomes held at a predetermined mounting position, and the card is locked. The external connections on the side are connected to corresponding terminal parts on the housing side. At this time, since the elastic holding piece fits into the notch at the side edge of the card, the card is stably held at the mounting position when the card is inserted.

In addition, when ejecting the installed card, press the card held in the installed position by a certain amount in the insertion direction (device extension side), and the pin member will disengage from the locking part of the heart-shaped cam groove to release the lock of the slide member. In the locked state, the slide member moves in the discharge direction (near side of the device) by the elastic force of the coil spring. Therefore, if the operation force for pressing the card is removed, the slide member moves in the ejection direction while engaging the card. On the contrary, the elastic holding piece can be pulled out by falling off from the notch.

As will be described later, when the card 5 is inserted into the card accommodating portion 6 from the card insertion port 8, the stepped portion 5a passes under the elastic holding piece 12 and moves toward the deep side of the device, and inserts the card 5 by a predetermined amount. At this point in time, the engaging portion 12a of the elastic holding piece 12 fits into the notch portion 5b from above.

Next, the operation of the above-mentioned card connection device will be mainly described with reference to FIG. 5 .

Fig. 1 has shown the standby state before the card 5 is inserted into the card connector, in this standby state

(Card ejection state), one end portion 11a of the pin member 11 is located at the deepest part of the outgoing path of the heart-shaped cam groove 13, and the slide member 9 is held on the front side of the bottom member 2 by receiving the elastic force of the coil spring 10. At this time, as shown in FIG.

If the card 5 is inserted into the card accommodating portion 6 from the card insertion port 8 in this state, after the fitting portion 12a of the elastic holding piece 12 abuts against the upper portion of the step portion 5a and elastically deforms in the upper release portion 3d As shown in FIG. 5( b ), the card 5 is held on the slide member 9 via the elastic holding piece 12 by falling from the top of the stepped portion 5 a and fitting into the notch 5 b from above. At this time, although the sliding member 9 is stopped, after the card 5 is further pushed into the card accommodating portion 6, since the front end portion of the card 5 abuts against the receiving portion 6a of the sliding member 9, by the pressing force of the card, The slide member 9 moves toward the device extension side against the elastic force of the coil spring 10 , and as this movement proceeds, the one end portion 11 a of the pin member 11 moves toward the front side of the forward path 13 a of the heart-shaped cam groove 13 .

Although the card 5 is further pushed in and the one end portion 11a of the pin member 11 reaches the frontmost part of the outgoing path 13a, the movement of the slide member 9 above it is restricted by the pin member 11, but here, if the pushing force to the card 5 is removed, Since the sliding member 9 returns to the front side of the device by a certain amount under the elastic force of the coil spring 10, the one end 11a of the pin member 11 is locked on the locking portion 13c of the heart-shaped cam groove 13 (see FIG. 4 ). . Thereby, the slide member 9 is locked and the card 5 is held at a predetermined mounting position. The card insertion is completed, and the external connection portion 14 of the card 5 is connected to the terminal portion 1 a of the corresponding terminal member 1 . During this period, the elastic holding piece 12 supported on the sliding member 9 also moves to the deep side of the device. As shown in FIG. The notch portion 5b of the card 5 is located, so the card 5 is stably held at the installation position in the card accommodating portion 6 .

In addition, in the state where the card insertion is completed, since the engaging portion 12a of the elastic holding piece 12 moves to the position directly below the discharge hole 3e of the cover member 3, the movement of the free end side of the elastic holding piece 12 passes through the position behind the discharge hole 3e. The lower surface of the flat plate portion 3a of the cover member 3 (the portion marked with reference numeral 3A) is restricted, so this portion functions as a restricting portion 3A that restricts movement in a direction away from the notch portion 5b of the fitting portion 12a. In addition, if the card 5 in the inserted state is to be forcibly pulled out, as shown by the dotted line in Figure 5(c), since the fitting part 12a is elastically deformed and moves in the discharge hole 3e, it is possible to prevent the fitting part 12a from contacting the cover. The parts 3 are butted and deformed.

Fig. 3 has shown the insertion completion state that card 5 is inserted on the card connecting device, and under this card insertion completion state, if card 5 is pushed into the deep side of the device (card insertion direction) by a certain amount, then One end portion 11a of the pin member 11 disengages from the lock portion 13c of the heart-shaped cam groove 13 and moves toward the circuit 13b, thereby releasing the locked state of the slide member 9 by the pin member 11 . Therefore, after the pushing force against the card 5 is removed, the coil spring 10 applies a force to the slide member 9 so that the slide member 9 moves to the front side of the device (card ejection direction). 9a The docked card 5 is moved from the card insertion port 8 to the protruding discharge position. As mentioned above, since the engaging portion 12a of the elastic holding piece 12 is located directly under the releasing portion 3d of the cover member 3 at the card ejecting position, in this state, after the card 5 is pulled out in the ejecting direction, the engaging portion 12a is elastically deformed in the upper release portion 3d and separated from the notch portion 5b, so the holding force by the elastic holding piece 12 can be released and the card 5 can be pulled out from the card insertion port 8.

In the card connecting device of the present embodiment constituted as described above, since the card 5 with the notch 5b formed on the side edge can be inserted into the case 7, a While applying the sliding member 9 to the force of the ejection direction, the elastic retaining piece 12 is fixed in a cantilever shape in such a way that it plane overlaps with the moving path of the card 5 on the sliding member 9, and the elastic holding piece 12 is formed in a state where the card insertion is completed. The fitting portion 12a on the free end side of the holding piece 12 is fitted into the notch 5b from above the card 5, so that the lateral width dimension due to the installation space of the elastic holding piece 12 can be prevented from becoming large, and the card connection can be facilitated like this. Miniaturization of the whole device. In addition, since there is a stepped portion 5a on the upper side edge of the card 5, and a notch portion 5b is formed in the middle of the stepped portion 5a, the elastic holding piece 12 can be arranged using the space divided by the stepped portion 5a of the card 5. Therefore, the overall height dimension of the card connecting device can also be reduced.

In addition, since the base member 2 made of synthetic resin for supporting the terminal member 1 that can be in contact with the external connection portion 14 under the card 5, and the cover member 3 made of metal integrated with the bottom member 2 constitute an insertable The housing 7 of the card 5 is provided with a restricting portion 3A and a release portion 3d on the flat plate portion 3a of the cover member 3, so the card 5 can be reliably held at the insertion completion position by the elastic holding piece 12, wherein the above-mentioned restricting The part 3A is used to limit the movement of the fitting part 12a of the elastic holding piece 12 from the notch part 5b of the card 5 at the card insertion completion position, and the release part 3d is used to allow the fitting part 12a to slip out of the notch part 5b at the card ejection position.
