Description

  The present invention relates to a card connector device that is used by mounting a card having an information storage function, and a card that can be mounted in the connector device.

  As this type of card connector device, a card receiver having a card storage space defined therein and a plurality of terminal members fixed to the card receiver, one end side of each terminal member is connected to the card storage space. It is widely known that the external connection part of the card inserted into the card storage space through the card insertion slot is in contact with the corresponding terminal member. Since the card has a rectangular shape in plan view and a plurality of external connection portions are disposed on one side thereof, the card inserted into the card storage space of the card connector device is upside down or back and forth. In such a case, a desired electrical connection cannot be obtained.

Therefore, conventionally, a notched portion as a mis-insertion preventing portion is formed at one corner of the front end portion of the card, and a leaf spring which can be slidably contacted with the notched portion by entering the card connector device from the side. There has been proposed an elastic piece such as that provided as a stopper that prevents erroneous insertion (see, for example, Patent Document 1). That is, when the card is inserted into the card storage space in a correct posture, the elastic piece slides into contact with the cutout portion of the card, so that the card can be inserted while retracting the elastic piece to the side. However, when the card is inserted into the card storage space in an undesired posture, the elastic piece abuts on a portion other than the notch of the card and cannot be retreated, so that the insertion of the card is prevented. It has become.
Japanese Patent Laid-Open No. 2001-223044 (page 3-5, FIG. 6)

  In the conventional card connector device described above, in order to prevent a predetermined card from being erroneously inserted in an undesired posture, an elastic piece that enters the card storage space from the side and functions as a stopper is provided. Since a plurality of types having different thickness dimensions and width dimensions are commercially available, cards that are not subject to attachment may be erroneously inserted with different sizes. In that case, a card thicker or wider than the card insertion slot opened in front of the card storage space will not be mistakenly inserted, but a card thinner or narrower than the card insertion slot will be mistakenly inserted. In particular, there is a high possibility that erroneous insertion of a card narrower than the card insertion slot cannot be prevented by the elastic piece. In other words, the above-described prior art has a problem in that erroneous insertion cannot be reliably prevented with respect to different types of non-target cards.

  The present invention has been made in view of the actual situation of the prior art, and a first object of the present invention is to provide a card connector that can reliably prevent not only a card to be mounted but also a different type of card that is not a target from being erroneously inserted. To provide an apparatus. A second object of the present invention is to provide a card suitable for enhancing the effect of preventing erroneous insertion of a card connector device.

  In order to achieve the first object, according to the present invention, there is provided a connector device that is used with a card having an inclined guide groove provided at a front end portion on one side, wherein the card is stored in the card from the card insertion slot. A card receiver inserted into the space; a plurality of terminal members supported by the card receiver and electrically connected to the card; and the card receiving space supported by the card receiver so as to be movable up and down. And when the card is inserted in a state where the movable restricting member is inserted into the inclined guide groove, the movable restricting member moves along the inclined surface of the inclined guide groove. It was configured to be guided to one side to allow insertion of the card.

  According to the card connector device thus configured, when a predetermined card having an inclined guide groove at the front end of one side is inserted into the card storage space in a correct posture, the movable restricting member is guided to the inclined surface of the inclined guide groove. Accordingly, since the card is retracted to the one side, insertion of the card is allowed. However, when the card is inserted in an upside-down or back-and-forth orientation, the movable restricting member abuts against a portion other than the inclined guide groove of the card and cannot be retracted. Insertion will be blocked. Further, in the case of a different type card not to be mounted, which is not provided with such an inclined guide groove, even if the thickness and width are smaller than the predetermined card, the different type card is inserted into the card storage space. Then, since there is a high possibility that the movable restricting member comes into contact with the tip of the movable restricting member in a non-retractable state, erroneous insertion can be prevented in advance. The movable restricting member also functions to hold the card mounted on the card connector device.

  In the above configuration, when the movable restricting member protrudes in the center in the width direction of the card storage space, it is possible to reliably prevent erroneous insertion even when the width of a different type of non-target card is extremely small. This is preferable because it is possible.

  Further, in the above configuration, the card receiver includes a base member made of synthetic resin for fixing the plurality of terminal members, and the card storage space is defined between the base member and the base member. In the case of a card connector device having a sheet metal cover member to be formed, the movable restricting member is constituted by a cantilevered elastic piece formed by cutting and raising a part of the cover member. Since it is not necessary to attach a single movable restricting member to the card receiver, the number of parts and the number of assembly steps can be reduced, which is preferable.

  In order to achieve the second object, the present invention provides a card that can be inserted and inserted into a card housing space of a card connector device in which a vertically movable movable restricting member projects into the card housing space. In this case, the front end of one side has an inclined guide groove as an erroneous insertion preventing portion, and an inclined surface extending obliquely from the one side toward the front end is formed in the inclined guide groove, and the card connector The movable restricting member that has entered the inclined guide groove when mounted on the apparatus is guided to the one surface along the inclined surface, thereby allowing insertion into the card storage space.

  According to the card configured as described above, when this is inserted into the card storage space of the card connector device in a correct posture, the movable restricting member is guided to the inclined surface of the inclined guide groove and retracted to the one side, The card can be inserted into a predetermined mounting position. However, if the orientation of the card when inserted is upside down or back and forth, the movable restricting member cannot be withdrawn because it abuts against a portion other than the inclined guide groove of the card, and therefore the card cannot be retracted. Insertion will be blocked. Further, in the case of a different type card not provided with such an inclined guide groove, even if the thickness dimension and width dimension are small, when the card is inserted into the card storage space, the movable restriction is provided at the leading end. Since there is a high possibility that the members will come into contact with each other in a state where they cannot be retracted, erroneous insertion can be prevented in advance.

  In the above configuration, when the inclined guide groove is provided in the center portion in the width direction of the front end portion of the card, the connector device to which the card is mounted causes the movable restricting member to protrude in the center portion in the width direction of the card storage space. Therefore, even when the width dimension of a different type of card that is not a target is extremely small, the erroneous insertion can be reliably prevented, which is preferable.

  In the card connector device of the present invention, the movable restricting member that can be retracted only when it enters the inclined guide groove of the card to be mounted is protruded into the card storage space, so that the card is erroneously inserted in an undesired posture. In addition to the case where it is made, such a mis-insertion can be prevented by the movable restricting member not only when a non-target different type card not provided with the inclined guide groove is erroneously inserted. Therefore, it is possible to obtain a card connector device that has an improved effect of preventing erroneous insertion without complicating the configuration.

  Moreover, since the card of the present invention has the inclined guide groove as the erroneous insertion preventing portion at the front end portion on one side, it is suitable for enhancing the erroneous insertion preventing effect of the card connector device.

  FIG. 1 is a perspective view of a card connector device and a card according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the connector device, and FIG. FIG. 4 is a cross-sectional view showing a state in which the card is being inserted into the connector device, FIG. 4 is a cross-sectional view showing a state in which the card has been inserted into the connector device, and FIG. It is sectional drawing which shows the state by which was inserted.

  As shown in these drawings, the card connector device according to the present embodiment is made of a synthetic resin base member 2 fixing a plurality of terminal members 1 and a sheet metal covering an upper opening of the base member 2. The cover member 3 and a card discharge mechanism 4 incorporated on one side of the base member 2 are mainly configured, and a casing formed by covering the base member 2 with the cover member 3 is a card receiver. 5

  The base member 2 is a molded product formed by inserting a plurality of terminal members 1 in a mold. A card storage space 6 is defined between the bottom plate 2 a of the base member 2 and the cover member 3, and the open end serves as a card insertion slot 7.

  Each terminal member 1 has a contact portion 1a whose one end can be in contact with the external connection portion 10a of the card 10, and a terminal portion 1b whose other end is soldered to a printed circuit board (not shown). An adhering portion 1 c between 1 a and the terminal portion 1 b is embedded in the bottom plate portion 2 a of the base member 2. The contact portion 1a is supported elastically so as to be movable up and down, and the tip portion of the contact portion 1a is disposed at a position protruding slightly above the upper surface of the bottom plate portion 2a on which the card 10 is mounted. For this reason, the contact portion 1a is in elastic contact with the lower surface of the card 10 inserted into the card storage space 6.

  The cover member 3 is formed by pressing a metal plate such as stainless steel, and has a flat plate portion 3a disposed to face the bottom plate portion 2a of the base member 2, and is provided on both the left and right sides and the rear end excluding the front end of the flat plate portion 3a. Is formed with a bent piece 3b. Each bent piece 3 b of the cover member 3 is fixed to the base member 2 by means such as snap coupling or caulking, and the flat plate portion 3 a covers the card storage space 6. In addition, the cover member 3 is provided with a movable restricting piece 8 formed by cutting and raising a part of the flat plate portion 3a. It protrudes. Since the movable restricting piece 8 is an elastic piece supported in a cantilever manner on the flat plate portion 3a, the tip end portion 8a is movable in the vertical direction.

  The card discharge mechanism 4 includes a slide member (not shown), a coil spring, and a slide pin, and these members are disposed on the bottom plate portion 2 a on the side of the card storage space 6. Here, the slide member is movable in the insertion / ejection direction of the card 10, and a heart-shaped cam groove is formed in the inner bottom portion of the slide member. The coil spring constantly biases the slide member toward the front side of the apparatus, and the slide pin is slidably engaged with the heart-shaped cam groove. When the slide member moves integrally with the card 10 inserted into the card storage space 6, the slide pin moves along the heart-shaped cam groove. However, since the configuration of the card ejection mechanism 4 is known, a detailed description thereof will be omitted.

  A card 10 used in this card connector device has a rectangular shape in a plan view, and a plurality of external connection portions 10 a are arranged on the lower surface side corresponding to each terminal member 1. The thickness and width of the card 10 are set to be slightly smaller than those of the card insertion slot 7, and an inclined guide groove 10 b is provided as an erroneous insertion prevention portion at the center in the width direction of the front end portion of the upper surface of the card 10. ing. An inclined surface 10c extending obliquely downward from the upper surface of the card 10 toward the front end side is formed in the inclined guide groove 10b, and the front end of the inclined surface 10c is continuous with the inner bottom surface of the inclined guide groove 10b. The left and right sides of the bottom surface and the inclined guide groove 10b are side walls of the inclined guide groove 10b. When the card 10 is inserted into the card insertion slot 7 in the posture shown in FIG. 1, the leading end 8a of the movable restricting piece 8 enters the inclined guide groove 10b, and when the card 10 is pushed in as it is, the movable restricting piece 8 moves upward. In order to evacuate, insertion of the card 10 into the card storage space 6 is allowed. And if the card | curd 10 is inserted to a predetermined mounting position, each external connection part 10a will contact with the contact part 1a of the corresponding terminal member 1. FIG.

  Next, the operation of the card connector device described above will be described.

  As shown in FIG. 1, when the card 10 is inserted into the card insertion slot 7 in the correct posture, as shown in FIG. 3, the distal end portion 8a of the movable restricting piece 8 enters the inclined guide groove 10b. The portion 8a is in sliding contact with the inclined surface 10c. Thereafter, when the card 10 is pushed in the insertion direction, the leading end 8a is guided to the inclined surface 10c and moves to the upper surface of the card 10, and the movable restricting piece 8 is retracted upward. The insertion of the card 10 is not hindered by the movable restricting piece 8, and the card 10 can be inserted into the card storage space 6 as it is. When the card 10 is inserted into the card storage space 6 in this manner, the front end of the card 10 pushes the slide member of the card ejection mechanism 4 against the urging force of the coil spring toward the back of the device, so that the sliding pin is Reach the forefront of the heart-shaped cam groove. When the pushing force to the card 10 is removed in this state, the slide member is slightly returned to the front side of the apparatus by the biasing force of the coil spring, and the slide pin is locked to the lock portion of the heart-shaped cam groove. The member is locked and the card 10 is held in a predetermined mounting position (see FIG. 4). In this state, the external connection portion 10a on the lower surface side of the card 10 contacts the contact portion 1a of the corresponding terminal member 1. . Since the movable restricting piece 8 retracted upward is in elastic contact with the upper surface of the card 10, the card 10 is sandwiched between the movable restricting piece 8 and the bottom plate portion 2a. It is not necessary to separately provide a holding member such as a leaf spring in order to prevent 10 from falling off.

  Further, when the card 10 in the mounted state is ejected, if the card 10 held at a predetermined mounting position is slightly pushed into the back of the apparatus, the sliding pin of the card ejecting mechanism 4 locks the heart-shaped cam groove. Since the slide member is released from the lock and the lock of the slide member is released, when the pushing force against the card 10 is removed, the slide member moves to the front side of the device by the elastic force of the coil spring, and accordingly the card 10 also moves through the slide member. Move to the front side of the device. As a result, the card 10 is discharged outward from the card insertion slot 7, and the leading end portion 8a of the movable restricting piece 8 is guided from the upper surface of the card 10 into the inclined guide groove 10b in the discharging process.

  However, when the card 10 is inserted in the card insertion slot 7 in the upside down direction or the front and back direction, the tip 8a of the movable restricting piece 8 is located at a place other than the inclined guide groove 10b of the card 10. Since it abuts, it cannot be retracted, and thus erroneous insertion of the card 10 is prevented.

  In addition, as shown in FIG. 5, when a different type of card 20 that is not to be mounted and is not provided with the inclined guide groove 10b is inserted into the card storage space 6 from the card insertion slot 7, the thickness dimension and the width dimension are different. Even if it is extremely small compared to the predetermined card 10, the tip 8 a of the movable restricting piece 8 protruding at the center in the width direction of the card storage space 6 can not be retracted by contacting the tip of the different card 20. Incorrect insertion can be reliably prevented. Needless to say, if the different card 20 has a size that cannot be inserted into the card insertion slot 7, it cannot be erroneously inserted.

  As described above, in the present embodiment, the inclined guide groove 10b is provided in the card 10 to be mounted with the card connector device, while the connector device side has the card storage space 6 corresponding to the inclined guide groove 10b. Since the protruding movable restricting piece 8 is provided and retracted only when the movable restricting piece 8 enters the inclined guide groove 10b of the card 10, the card 10 is erroneously inserted in an undesired posture. In addition to the case, even when a different type of card not subject to the inclined guide groove 10b is erroneously inserted, such erroneous insertion can be reliably prevented by the movable restricting piece 8. In addition, the movable restricting piece 8 is formed by cutting and raising a part of the cover member 3 made of sheet metal, and is not attached separately to the card receiver 5, so that it does not increase the number of parts and the number of assembly steps. . Therefore, the effect of preventing erroneous insertion of the card connector device can be remarkably enhanced without complicating the configuration.

  In the present embodiment, an inclined guide groove 10b is formed at the front end portion of the upper surface of the card 10, and the movable restricting piece 8 is formed so as to protrude into the card storage space 6 from above in the card connector device. Although provided, the inclined guide groove 10b may be formed at the front end of the lower surface of the card 10. In this case, the card connector device is provided with a movable restricting piece 8 so as to protrude into the card storage space 6 from below. What is necessary is just to provide.

  Further, when the card receiver 5 of the card connector device does not have a cover member made of sheet metal, a single movable restricting member that protrudes into the card storage space 6 and can move up and down similarly to the movable restricting piece 8 is used as the card. You may make it the structure attached to the receptor 5. FIG.
