Description

  The present invention relates to a card connector to which at least two types of electronic function cards having different shapes are selectively attached.

  As described in the following patent documents, a small and thin electronic function card called a memory card is mounted and used in a digital camera, a digital video camera, or a personal computer. This electronic functional card contains a memory chip, an IC chip that functions as a memory controller, and the like in a small and thin case (sometimes referred to as a housing) formed of a synthetic resin material. A plurality of external connection portions that are electrically connected to an internal electronic circuit are provided on the back surface of the case.

  There are several types of electronic function cards of this type with different case shapes. Cards with different shapes have different storage capacities of the memory chips provided in them, or have interface specifications. It is different.

  The card connector described in Patent Document 3 below is one in which two types of cards having different shapes are selectively attached. The card connector locks a slider that moves in the card insertion direction in the housing, a biasing member that biases the slider toward the insertion port, and a slider that is pushed into the housing with the card. And a locking mechanism. A contact portion is integrally formed on the slider, a stopper member that is supported by the slider and moves in a direction orthogonal to the card insertion direction, and a stopper member that is rotatably supported by the slider. And an arm member for moving the.

  When a long card with a large vertical length is inserted, the arm member is rotated at the tip of the card, and the stopper member retreats to a position where it does not touch the card. It is inserted deeper than the stopper member and comes into contact with the contact portion. If the card is pushed in as it is, the slider moves to the back side and is locked, and the external connection portion provided on the card is connected to the first connection terminal provided on the card connector.

On the other hand, a short card having a small length in the vertical direction has a defective portion facing the arm member when inserted in a normal posture. When the short card is mounted in a normal posture, the arm member does not rotate because the defect portion faces the arm member, and the leading end of the card hits the abutting portion provided on the slider. . When the card is pushed in as it is, the slider moved to the back side together with the card is locked, and the external connection portion provided on the short card is connected to the second connection terminal provided on the card connector.

  In the card connector described in Patent Document 3, a stopper member that restricts insertion of a short card is positioned closer to the insertion slot than a contact portion that a long card hits, and the stopper member can be operated freely. The guiding slide groove is also provided closer to the insertion opening than the contact portion. Therefore, the contact portion and the stopper member are arranged with a long distance in the card insertion direction in the casing, and it is necessary to increase the depth dimension of the casing. It becomes difficult to realize.

  In addition, since the leading end portion of the long card positioned by hitting the contact portion and the leading end portion of the short card positioned by hitting the stopper portion are positioned away from each other in the casing, If the difference in length between the short card and the short card is small, the rear end of the short card may protrude greatly from the insertion slot to the near side when the short card is mounted in the housing.

  Further, since the guide groove for instructing the stopper member to be movable is provided in a region through which the long card passes, the guide groove is arranged so as to overlap the long card. It becomes the cause which obstructs the thickness reduction. Further, since the guide groove and the stopper member cannot be formed long in the front-rear direction, it is difficult to make the stopper member move smoothly.

  The present invention solves the above-described conventional problems, and is a card connector to which at least two types of cards can be attached, and the two types of cards can be positioned at positions where the front end portions thereof are not separated from each other in the front-rear direction. An object of the present invention is to provide a card connector in which the movable stopper portion can be stably operated and the entire thickness can be reduced.

The present invention includes a housing having an insertion slot into which the first card and the second card are selectively inserted in a direction parallel to the surface of the card, and the first card and the second card provided in the housing. A reference stopper portion against which the second card hits, a movable stopper portion which is positioned closer to the insertion port than the reference stopper portion and against which the second card hits, A first connection terminal connected to the external connection portion and a second connection terminal connected to the external connection portion of the second card;
A guide portion extending perpendicularly to the card insertion direction is provided on the inner side of the housing with respect to the contact portion between the reference stopper portion and the first card, and the movable guide portion is guided to the guide portion. The movable guide part is movable between a restriction position where the second card hits and a restriction release position which allows the first card to move to a position where it hits the reference stopper part. The stopper surface to which the second card is formed is positioned closer to the insertion port than the contact portion,
When the first card is inserted, the movable stopper portion is moved from the restriction position to the restriction release position by the insertion force, and when the second card is inserted, the movable stopper portion is It exists in the said control position.

  In the card connector according to the present invention, the movable stopper portion is moved between the restriction position and the restriction release position by being guided by a guide portion provided behind the contact portion between the reference stopper portion and the first card. To do. In addition, the stopper surface of the movable stopper portion is located closer to the insertion opening than the contact portion. Therefore, the contact portion and the stopper surface can be disposed at positions close to each other in the front-rear direction, and the depth of the housing can be easily reduced. In addition, it is easy to prevent the position of the rear end portion of the normally installed first card from greatly differing from the position of the rear end portion of the normally installed second card. Further, since the guide portion is provided on the back side with respect to the abutting portion, the guide portion can be easily made relatively large in the front-rear direction, and the operation of the movable stopper portion is also stabilized.

  In addition, since the guide portion does not overlap the first card, the thickness dimension of the housing can be easily reduced.

  In the card connector of the present invention, a card having a shape other than the first card and the second card may be further selectively inserted into the housing.

  For example, the present invention is provided with a rotatable member having a rotation fulcrum on the insertion opening side of the movable stopper portion, and the rotatable member is connected to the movable stopper portion, When the first card is inserted, the rotating member is rotated by the first card, and the movable stopper portion is moved from the restriction position to the restriction release position.

  However, according to the present invention, the rotating member is not provided, and when the first card is inserted, the first card directly hits the movable stopper portion, and the first card is inserted. The movable stopper portion may be moved to the restriction release portion by a component force.

  In the present invention, the first card is formed with a groove into which a part of the movable stopper portion enters, and the second card hits a portion of the movable stopper portion into the groove. Those having a stopper surface are preferred.

  If the movable stopper portion has a portion that enters the groove of the first card, and a stopper surface is provided on this portion, the contact area between the second card and the movable stopper portion can be increased, and the second card This ensures that the movable stopper portion is pushed in.

  In the present invention, for example, the movable stopper portion is biased toward the restriction position.

In the present invention, the housing includes a slider that moves in the card insertion direction, a biasing member that biases the slider toward the insertion slot, and a position in which the slider moves in the card insertion direction. And a locking mechanism that locks with
The reference stopper portion and the guide portion are provided on the slider, and the movable stopper portion is operably mounted on the slider.

  In the present invention, the reference stopper portion, the guide portion, and the movable stopper portion may not be mounted on the slider but may be disposed at predetermined positions inside the housing.

  In the present invention, it is preferable that the upper surface of the reference stopper portion, the upper surface of the movable stopper portion, and the upper surface of the slider are located on the same surface.

  In the above configuration, since the reference stopper portion, the guide portion, and the movable guide portion can be disposed within the thickness range of the slider, the card connector can be thinned. Furthermore, the rotating member can also be arranged within the thickness range of the slider.

  In the card connector according to the present invention, the movement of the movable stopper portion can be stabilized, and the depth dimension of the housing can be reduced. Therefore, even if there is a slight difference in the longitudinal length between the first card and the second card, the rear end of the first card and the rear end of the second card are substantially at the same position. As such, the first card and the second card can be positioned.

The front surface 1a and the back surface 1b are planes parallel to each other, and the distance between the front surface 1a and the back surface 1b is the thickness dimension T1 of the first card C1. As shown in FIG. 12, a plurality (13) of external connection portions 5 are exposed in front of the back surface 1b. The surface of the external connection portion 5 is substantially flush with the back surface 1 b of the case 1.

  Here, “front surface” and “back surface” are names for convenience to distinguish between the surface having the external connection portion 5 and the surface not having the external connection portion 5, even if the front surface 1 a is attached to the card connector 20. Alternatively, it may be mounted with the back surface 1b facing upward.

  As shown in FIGS. 10 to 12, the case 1 has a front end portion 1c and a rear end portion 1d. It also has a right side 1e and a left side 1f.

  As shown in FIG. 11, the front end 1c is a plane perpendicular to the front surface 1a, and a front inclined surface 2 is formed at the corner between the front surface 1a and the back surface 1b. The rear end 1d is a plane perpendicular to the front surface 1a and the back surface 1b. The right side 1e and the left side 1f are planes perpendicular to the front surface 1a and the back surface 1b. As shown in FIG. 10, the boundary portion between the front end portion 1c and the right side portion 1e and the boundary portion between the front end portion 1c and the left side portion 1f, that is, the left and right side portions of the front end portion 1c are front portions that are part of a cylindrical surface. Corner curved surfaces 3 and 3 are formed. The rear corner curved surface 4, which is a part of the cylindrical surface, is also formed at the boundary between the rear end 1d and the right side 1e and the boundary between the rear end 1d and the left side 1f, that is, both the left and right sides of the rear end 1d. 4 is formed.

  As shown in FIG. 10, in the plan view of the case 1 viewed from the front surface 1a side, the shape of the case 1 is symmetrical to the left and right via a center line OO extending forward and backward. And the length dimension L0 of the vertical direction which is a dimension from the front-end part 1c to the rear-end part 1d is a rectangular shape longer than the width dimension W0 which is a dimension from the right side part 1e to the left side part 1f.

  In the front portion of the case 1, guide grooves 6 and 6 that are recessed from the right side 1 e and the left side 1 f toward the center line OO are formed. The guide grooves 6, 6 are parallel to the right side portion 1e and the left side portion 1f, and are located on the inner side surfaces 6a, 6a located on the inner side by a distance W1 from the right side portion 1e and the left side portion 1f toward the center line OO, and the back surface 1b. And inner bottom surfaces 6c, 6c parallel to each other. Inclined portions 6b and 6b are formed between the rear end portion of the right guide groove 6 and the right side portion 1e, and between the rear end portion of the left guide groove 6 and the left side portion 1f, respectively. . The inclined portions 6b and 6b are surfaces that gradually move away from the center line OO toward the rear, and are flat surfaces or curved surfaces having a curvature.

  As shown in FIG. 11, the guide grooves 6 and 6 are recessed from the front surface 1a of the case 1 toward the back surface 1b. The distance from the front surface 1a of the case 1 to the inner bottom surface 6c of the guide groove 6, that is, the depth dimension t1 from the front surface 1a to the back surface 1b of the guide grooves 6, 6 is the total thickness dimension T1 of the first card C1. It is almost 1/2. Further, as a result of the guide grooves 6 and 6 being formed to be recessed from the front surface 1a, thin-walled portions 7 and 7 that are sandwiched between the back surface 1b and the inner bottom surfaces 6c and 6c are formed on the back surface side. Is formed. The thickness dimension t2 of the thin portions 7 and 7 is also approximately ½ of the overall thickness dimension T1 of the first card C1.

  The guide grooves 6 and 6 are opened forward at the left and right sides of the front end 1c. Therefore, as shown in FIG. 12, the thickness dimension of the front end portion 1c is T1 at most of the center thereof, but the thickness dimension is t2 at both sides.

  On the right side 1e and the left side 1f of the case 1, latching recesses 8 and 8 are formed at a position rearward of the rear ends of the guide grooves 6 and 6. The latching recesses 8 and 8 have inner ends 8a and 8a that are located closer to the center line OO than the right side 1e and the left side 1f and are parallel to the right side 1e and the left side 1f. The width dimension W2 from the right side 1e to the inner end 8a and the width dimension W2 from the left side 1f to the front inner end 8b are substantially the same as the width dimension W1 of the guide grooves 6 and 6. Moreover, the latching recessed parts 8 and 8 have the front inner end 8b and the rear inner end 8c.

  As shown in FIGS. 11 and 12, the latching recesses 8 and 8 have inner bottom ends 8d and 8d, and the inner bottom ends 8d and 8d are parallel to the back surface 1b. The dimension from the surface 1a to the inner bottom ends 8d and 8d is the depth dimension t3 of the latching recesses 8 and 8, and this depth dimension t3 is slightly larger than the depth dimension t1 of the guide groove 6.

  When the first card C1 is attached to the card connector 20, the holding portion 53 (see FIG. 2) formed of a leaf spring passes through the guide groove 6 and fits into the latching recess 8. The first card C1 is held by the slider 41 in the card connector 20. As shown in FIG. 10, since the inclined portions 6b and 6b are formed at the rear ends of the guide grooves 6 and 6, the holding portion 53 that has passed through the guide groove 6 is guided to the inclined portions 6b and 6b. Fits smoothly into the latching recesses 8 and 8.

  Furthermore, as shown in FIG. 11, since the depth dimension t3 of the latching recesses 8 and 8 is larger than the depth dimension t1 of the guide grooves 6 and 6, the holding portion 53 that has passed through the guide grooves 6 and 6 is formed. It becomes easy to enter the latching recesses 8 and 8.

  As shown in FIG. 10, a knob recess 9 that is recessed from the surface 1 a is formed slightly inside the rear end 1 d of the case 1. As shown in FIG. 1, when the first card C <b> 1 is attached to the card connector 20, the rear end portion having the knob recess 9 protrudes from the card connector 20. The first card C <b> 1 can be pulled out from the card connector 20 by hooking a fingernail on the knob 9.

(The shape of the second card)
As shown in FIG. 8, a second card C2 can be attached to the card connector 20 in addition to the first card C1.

  The second card C2 has a plastic case 11, in which a memory chip such as a flash memory, an IC chip that functions as a memory controller, and the like are housed.

  As shown in FIG. 13, the case 11 has a front surface 11 a directed to the front side of the paper in FIG. 13 and a back surface opposite to the front surface 11 a. The case 11 has a front end portion 11c, a rear end portion 11d, a right side portion 11e, and a left side portion 11e. The front end portion 11c, the rear end portion 11d, the right side portion 11e, and the left side portion 11e are all formed on the surface 11a and The end surface is perpendicular to the back surface. A plurality of external connection portions that are electrically connected to the circuit in the case 11 are provided in the front portion of the back surface.

  The longitudinal length L3 of the second card C2 is shorter than the longitudinal length L0 of the first card C1 shown in FIG. The second card C2 has a defective portion 16 formed in the front portion of the right side portion 11e, and an inclined portion 16b is formed at the rear end portion of the defective portion 16. The defect 16 is formed through the case 11 in the thickness direction. As a result, in the second card C2, the width dimension W4 of the front part where the defect part 16 is formed is shorter than the width dimension W3 behind the inclined part 16b.

  Both the width dimension W3 and the width dimension W4 are shorter than the width dimension W0 of the first card C1. Further, the difference between the width dimension W3 and the width dimension W4, that is, the width dimension of the missing portion 16 is slightly wider than the width dimension W1 of the guide groove 6 of the first card C1.

  Front corner curved surfaces 13, 13 are formed on the left and right sides of the front end portion 11c of the case 11, and rear corner curved surfaces 14, 14 are formed on the left and right sides of the rear end portion 11d.

  A latching recess 18 is formed on the right side of the second card C2 so as to be located behind the inclined portion 16b. The latching recess 18 is formed through the case 11 in the thickness direction. The longitudinal dimension L5 and the width dimension W5 of the latching recess 18 are substantially the same as the length dimension L4 and the width dimension W2 of the latching recess 8 formed in the first card C1.

  As shown in FIG. 13, a knob recess 19 is formed in the rear end portion of the surface 11 a of the case 11.

  The thickness dimension of the second card C2 is smaller than the thickness dimension T1 of the first card C1. The second card C2 has, for example, the same shape as that called “microSD card”.

  The first card C1 and the second card C2 differ not only in the shapes of the case 1 and the case 11 but also in the specifications. This difference in specifications is, for example, a difference in driving voltage, that is, a voltage to be supplied to the circuits in the cases 1 and 11 through the external connection for power. Alternatively, the memory capacity of the memory chips stored in the case 1 and the case 11 is different.

(Structure of card connector)

Further, the height dimension Ta of the storage area for guiding and storing the card is determined by the height dimension from the upper surface 28 b of the bottom wall portion 28 of the housing body 22 to the lower surface of the ceiling plate 23 a of the lid 23. The height dimension Ta is substantially the same as the thickness dimension T1 of the first card C1 or slightly larger than the thickness dimension T1.

  As shown in FIGS. 2 and 4, the inner surface of the left wall portion 27 of the housing body 22 is a guide reference surface 27b, and the left side portion 1f of the first card C1 slides on the guide reference surface 27b. However, it is inserted toward the back side ((a) side) of the housing 21. A right guide surface 24b is formed on the front wall portion 24 of the housing body 22, and the right side portion 1e of the first card C1 is guided along the right guide surface 24b.

  The distance between the guide reference surface 27b on the inner surface of the left wall portion 27 and the right guide surface 24b of the front wall portion 24 is the width dimension Wa of the storage area, and this width dimension Wa is the width dimension of the first card C1. The dimensions are approximately the same as or slightly larger than W0.

  As shown in FIG. 4, an insertion port 29 having an opening area of Ta × Wa is opened at the front end of the housing 21, and both the first card C <b> 1 and the second card C <b> 2 are from the insertion port 29. It is inserted toward the inside of the housing 21.

  As shown in FIGS. 2 and 4, an upper guide portion 31 that is formed integrally with the left wall portion 27 and extends into the storage area is provided inside the housing body 22. As shown in FIG. 4, the height dimension Tb from the upper surface 28b of the bottom wall part 28 to the lower surface of the upper guide part 31 is substantially the same as the thickness dimension t2 of the thin part 7 of the first card C1 shown in FIG. Or slightly wider than that. Therefore, as shown in FIGS. 2, 6 and 7, when the first card C1 is inserted in a normal orientation with the front end 1c facing forward and the surface 1a facing upward, The thin-walled portion 7 formed in the front enters the lower side of the upper guide portion 31, and the first card C1 can be mounted to the back of the housing 21. However, as shown in FIG. 3, when the first card C1 is inserted with its rear end 1d facing forward or inserted in the reverse direction, the housing body 22 hits the upper guide 31 and The first card C1 is not inserted to the back of the housing 21.

As shown in FIG. 4, the regulation elevating member 32 projects upward from a notch formed in the bottom wall portion 28, and the regulation elevating member 32 is biased toward the projecting posture by a spring member (not shown). . Moreover, the surface which faces the insertion port 29 side of the regulation raising / lowering member 32 is the inclined surface 32a. The inclined surface 32 a has a shape that gradually increases from the upper surface 28 b of the bottom wall portion 28 toward the back side ((a) side) of the housing 21.

  As shown in FIG. 5, the width dimension from the right side surface of the regulating elevating member 32 to the inner side surface 41 a of the slider 41 is Wb. The width dimension Wb is narrower than the width dimension W0 of the first card C1 shown in FIG. 10, and is substantially the same as or slightly smaller than the width dimension W3 of the rear portion of the second card C2 shown in FIG. Widely set.

  Therefore, as shown in FIG. 8, when the second card C2 is inserted from the insertion slot 29, the second card C2 passes between the regulation elevating member 32 and the inner side surface 41a of the slider 41. It is possible to enter the back of the body 21. When the first card C1 is inserted from the insertion slot 29, the front inclined surface 2 and the back surface 1b of the first card C1 ride on the inclined surface 32a of the regulating elevating member 32, and the force at that time The regulation elevating member 32 is pushed down. Thereafter, the first card C <b> 1 passes over the depressed regulation elevating member 32 and moves to the back of the housing 21.

  As shown in FIGS. 5 and 9, a holding recess 41c is formed in the upper portion of the front side ((b) side) of the slider 41, and a holding leaf spring that functions as a holding member in the holding recess 41c. 52 is provided. The holding plate spring 52 is formed of a metal plate that functions as a plate spring material, bent into a U shape, and fitted into the holding recess 41c.

  A holding portion 53 is integrally formed at the free end of the holding leaf spring 52, and the holding portion 53 protrudes to the left in the drawing from the inner side surface 41 a of the slider 41. The holding portion 53 is bent in a V shape, and a portion facing the front side ((b) side) is an inclined guide portion 53a. The inclination guide part 53a is inclined so as to gradually move away from the card toward the front side ((b) side). A portion of the holding portion 53 that faces the back side ((a) side) is a locking portion 53b, and this locking portion 53b is in a direction substantially orthogonal to the front-rear direction ((a)-(b) direction). Is formed.

  As shown in FIG. 9, the holding portion 53 protrudes leftward in the upper portion of the inner side surface 41 a of the slider 41. As shown in FIG. 4, the height dimension from the upper surface 28b of the bottom wall portion 28 of the housing body 22 to the lower edge of the holding portion 53 is set to be substantially the same as Tb or slightly wider than Tb. Has been.

  As shown in FIGS. 3 and 5, a first connection terminal 55 is provided on the back side ((a) side) of the housing body 22. The first connection terminals 55 are arranged in the same number and the same pitch as the external connection portions 5 exposed on the back surface 1b of the first card C1 shown in FIG. A terminal support plate 57 is provided on the back side of the bottom of the housing body 22, and a plurality of small holes 57 a are formed in the terminal support plate 57 so as to penetrate vertically. As shown in FIG. 3, the first connection terminals 55 are bent upward in a mountain shape, and each protrudes upward from the small hole 57a. The first connection terminal 55 is elastically deformable so that it can be retracted into the small hole 57a.

  In each of the first connection terminals 55, first external terminals 56 are continuously formed in a one-to-one relationship. As shown in FIG. 5, each first external terminal 56 protrudes rearward from the rear wall portion 25 of the housing body 22. The first connection terminal 55 and the first external terminal 56 are individually connected, and are formed of a conductive metal plate having a surface plated with a low resistance noble metal material such as gold.

  As shown in FIGS. 3 and 5, a second connection terminal 58 is provided closer to the insertion port 29 than the first connection terminal 55. The second connection terminals 58 are arranged in the same number and the same pitch as the external connection portions exposed on the lower surface of the second card C2 shown in FIG. As shown in FIG. 3, a movable support plate 61 is provided at the bottom of the housing body 22, and a plurality of small holes 61 a are formed in the movable support plate 61 so as to penetrate vertically. Each of the second connection terminals 58 is bent upward in a mountain shape and protrudes upward from the small hole 61a.

  The movable support plate 61 is supported so as to be rotatable up and down about an axis provided on the near side ((b) side) of the second connection terminal 58. The movable support plate 61 is lifted upward by the elastic force of the second connection terminal 58.

  When the first card C1 is inserted through the insertion slot 29, the front inclined surface 2 of the first card C1 rides on the movable support plate 61, and the movable support plate 61 is moved by the back surface 1b of the first card C1. Pushed down. When the movable support plate 61 is pushed down and pivots downward, the second connection terminal 58 is pushed down by the movable support plate 61, and each second connection terminal 58 becomes a small hole in the movable support plate 61. Retreat inside 61a. Therefore, the external connection portion 5 provided on the back surface 1b of the first card C1 passes above the second connection terminal 58 and moves to the back without hitting the second connection terminal 58.

  On the other hand, when the second card C2 shown in FIG. 13 is inserted from the insertion slot 29, the second card C2 is movable with the second connection terminal 58 because the second card C2 is smaller in thickness than the first card C1. Lifted by the support plate 61, the second card C <b> 2 is pressed against the lower surface of the ceiling plate 23 a of the lid body 23. Then, each second connection terminal 58 is conducted to an external connection portion provided on the back surface of the second card C2.

  As shown in FIG. 5, each of the second connection terminals 58 is integrally formed with a second external terminal 59, and each of the second external terminals 59 is at the front of the bottom of the housing body 22. It protrudes to the side ((b) side). The second connection terminal 58 and the second external terminal 59 are integrally formed of a conductive metal plate whose surface is plated with a low resistance noble metal material such as gold.

(Normal insertion operation of the first card)
Next, the mounting operation of the first card C1 to the card connector 20 will be described.

  2, 6 and 7 show the operation when the first card C1 is mounted in the normal orientation.

  When the card is not loaded, as shown in FIG. 5, the slider 41 moves to the insertion slot 29 side ((b) side), and on the slider 41, the rotating member 44 rotates counterclockwise. The movable stopper 47 is moved to the left. At this time, the posture of the rotating member 44 is the first posture, and the movable stopper portion 47 is the restriction position.

  When the rotating member 44 is in the first posture, as shown in FIG. 4, when the inside of the housing 21 is viewed from the insertion port 29, the movable stopper portion 47 is formed on the upper right side behind the insertion port 29. The first stopper surface 48a and the second stopper surface 48b appear, and the holding portion 53 formed by the holding leaf spring 52 appears before the first stopper surface 48a and the second stopper surface 48b. In addition, an upper guide portion 31 appears on the upper left side behind the insertion port 29, and a regulation elevating member 32 appears on the lower left portion. Further, the movable support plate 61 is lifted from the upper surface 28 a of the bottom wall portion of the housing body 22, and the second connection terminal 58 protrudes upward from each small hole 61 a of the movable support plate 61.

  When the first card C1 is inserted through the insertion slot 29 in a normal posture with the front end 1c facing forward and the surface 1a facing upward, the first card C1 is placed on the right side of the casing 1 of the first card C1. The formed thin portion 7 passes below the holding portion 53 formed by the holding leaf spring 52 provided on the slider 41.

  Further, the thin portion 7 on the right side passes under the erroneous insertion preventing convex portion 44a of the rotating member 44 shown in FIG. 9, and the region of the height Tb shown in FIG. Moving. At this time, the right front corner curved surface 3 of the first card C <b> 1 hits the sliding surface 44 b positioned below the erroneous insertion preventing convex portion 44 a of the rotating member 44. When the first card C1 is pushed in, the sliding surface 44b is pushed by the front corner curved surface 3, and the turning member 44 is turned clockwise as shown in FIGS. 2 and 6, along with this. Thus, the movable stopper portion 47 on the slider 41 is moved rightward. Therefore, the tip of the thin portion 7 on the right side of the first card C1 passes under the first stopper surface 48a located on the left side of the stopper surface 48 formed on the movable stopper portion 47. Move further back. The posture of the rotating member 44 at this time is the second posture, and the movable stopper 47 is the restriction release position.

  On the other hand, the thin front portion 7 on the left front side of the first card C1 slides on the inclined surface 32a of the restriction elevating member 32 shown in FIGS. The member 32 is pushed down. And the thin part 7 on the left side enters the gap where the height dimension between the upper surface 28b of the bottom wall part 28 shown in FIG. 4 and the upper guide part 31 is Tb. As shown in FIGS. 2 and 6, the front end 1 c of the first card C <b> 1 hits a reference stopper surface 45 a of a reference stopper portion 45 provided on the back side of the slider 41.

  During this time, the holding portion 53 of the holding leaf spring 52 provided on the slider 41 passes through the inside of the guide groove 6 on the right side of the first card C1, that is, passes over the thin portion 7 and It hits the rear inclined part 6b. Since the holding portion 53 is pushed rightward by the inclined portion 6 b, the holding leaf spring 52 is deformed and the holding portion 53 is temporarily retracted into the holding recess 41 c of the slider 41. Then, when the holding portion 53 slides on the right side 1e of the first card C1 and reaches the latching recess 8, the holding portion 53 is fitted into the right latching recess 8 by the elastic return force of the holding plate spring 52. .

  At this time, since the inclined guide part 53a facing the front side of the holding part 53 slides on the inclined part 6b inclined in the same direction, the first card C1 is pushed into the housing 21 with a light force, The holding portion 53 can be fitted into the latching recess 8. After the fitting, the locking portion 53b formed in the holding portion 53 in a direction substantially orthogonal to the card insertion direction is hooked to the front inner end 8b of the locking recess 8, so that the first Card C1 is less likely to come out in the forward direction (direction (b)).

  When the first card C1 is further pushed in after the holding portion 53 is fitted in the latching recess 8, the reference stopper surface 45a formed on the slider 41 is pushed by the front end 1c of the first card C1, and the first card C1 is pushed. The one card C1 and the slider 41 move together to the back side. When the first card C1 reaches the mounting completion position shown in FIG. 7, the lock portion 42b of the groove cam 42 formed on the slider 41 is engaged with the tip portion 36b of the lock pin 36, and the slider 41 is moved. Locked in that position.

  At this time, each of the first connection terminals 55 provided on the back side of the housing main body 22 is connected to each of the external connection portions 5 exposed on the back surface 1b of the first card C1 by pressing. At this time, the movable support plate 61 is pushed down by the back surface 1b of the first card C1, and the second connection terminal 58 moves backward from the upper surface of the movable support plate 61. Therefore, the second connection terminal 58 does not contact the external connection portion 5 of the first card C1.

  When the first card C1 is detached from the card connector 20, as shown in FIG. 7, the first card C1 is pushed to the back side ((a) side) from the normally mounted state. When the slider 41 moves slightly backward together with the first card C1, the tip end portion 36b of the lock pin 36 is disengaged from the lock portion 42b of the groove cam 42, and the slider 41 is moved forward ((b ) Side). Therefore, as shown in FIGS. 2 and 6, the slider 41 returns to the initial position, and the rear end portion of the first card C <b> 1 is protruded from the insertion slot 29.

(Incorrect insertion of the first card)
FIG. 3 shows a state where the first card C1 is inserted from the insertion slot 29 with the rear end 1d facing forward.

  As shown in FIG. 4, since the erroneous insertion prevention convex portion 44a of the rotating member 44 is located on the card insertion path, the rear end portion 1d of the first card C1 is the erroneous insertion prevention convex portion. It hits 44a. If the first card C1 is pushed in as it is, the rotating member 44 rotates clockwise, and the movable stopper portion 47 moves rightward. However, also at this time, the rear end portion 1d remains in contact with the erroneous insertion prevention convex portion 44a, and the first card C1 does not advance further to the back side relative to the slider 41. Thereafter, when the first card C1 is pushed in, the slider 41 is pushed together, but the rear end 1d of the first card C1 remains in contact with the erroneous insertion prevention convex portion 44a. The card C1 cannot completely enter the housing 21.

  Further, when the slider 41 is pushed into the back side together with the first card C1, the rear end 1d of the first card C1 hits the upper guide portion 31 located on the left side of the storage area, and beyond that, The card C1 and the slider 41 cannot move to the back side.

  Therefore, the first card C1 is not inserted until the external connection portion 5 of the first card C1 and the first connection terminal 55 provided on the housing 21 are connected. At this time, since the protruding amount of the first card C1 from the insertion slot 29 is longer than that during normal mounting, the user can easily recognize that the first card C1 has been erroneously inserted.

  Also, when the first card C1 is inserted from the insertion slot 29 with the front end 1c facing forward and the back 1b facing upward, as shown in FIG. 3, the rear end 1d is inserted forward. It is the same as when

(Normal insertion of the second card)
FIG. 8 shows a state in which the second card C2 is normally attached to the card connector 20.

  The width dimension W3 of the second card C2 is smaller than the width dimension W0 of the first card C1. Therefore, when the second card C2 is inserted so as to be biased to the right with respect to the insertion slot 29, the second card C2 has a width dimension Wb between the regulation lifting member 32 and the inner side surface 41a of the slider 41. The inside of the region (see FIG. 5) is moved and inserted into the back side.

  Since the second card C <b> 2 has the missing part 16 on the right side, the tip of the card does not hit the erroneous insertion preventing convex part 44 a of the rotating member 44. Therefore, the rotating member 44 remains in the first posture rotated counterclockwise, and the movable stopper portion 47 remains moved to the left side. Then, the front end portion of the second card C2 hits the first stopper surface 48a and the second stopper surface 48b (see FIGS. 4 and 9) of the movable stopper portion 47, and at this time, the holding portion of the holding leaf spring 52 53 fits into a recess 18 that vertically penetrates the right side of the case of the second card C2.

  As shown in FIG. 9, the stopper surface 48 of the movable stopper portion 47 has a first stopper surface 48a and a second stopper surface 48b. The first stopper surface 48a extends to a position where it overlaps with the thin portion 7 of the first card C1 when the first card C1 is inserted. Thus, when the second card C2 is inserted, the front end portion 11c of the first stopper surface 48a extends to the left to the position where it overlaps with the first card C1. It can hit both the surface 48a and the second stopper surface 48b. That is, the area where the front end portion 11c of the second card C1 and the movable stopper portion 47 meet can be ensured as wide as the first stopper surface 48a is provided. Therefore, after that, when the second card C2 is pushed in, the slider 41 is surely pushed into the back side together with the second card C2.

  When the slider 41 is pushed into the housing 21 together with the second card C2, the left side of the second card C2 is inserted to the back of the housing 21 without hitting the upper guide portion 31, as shown in FIG. Is done. Therefore, the front end portion 36b of the lock pin 36 is hooked on the lock portion 42b of the groove cam 42, and the slider 41 is locked.

  Since the thickness dimension of the second card C2 is smaller than the thickness dimension of the first card C1, the movable support plate 61 is not pushed down by the second card C2, and a small hole in the movable support plate 61 is provided. The second connection terminals 58 protruding from 61a are individually connected to external connection portions provided on the lower surface of the second card C2.

(Incorrect insertion of second card)
If the second card C2 is inserted in a direction reverse to the front and rear direction shown in FIG. 8, that is, with the rear end portion 11d oriented toward the insertion slot 29, the first card C1 shown in FIG. Similarly to the time, the rear end portion 11 d of the case 11 hits the erroneous insertion preventing convex portion 44 a provided on the rotating member 44. Therefore, the second card C2 is prevented from entering the inside of the housing 21. At this time, since the protrusion amount of the second card C2 from the insertion slot 29 becomes long, the user can easily recognize that the insertion is in the wrong direction. At this time, when the second card C2 inserted in the wrong posture without recognizing the erroneous insertion is further pushed into the housing 21, the card is more than the erroneous insertion preventing convex portion 44a. Since it does not go into the back, the amount of protrusion from the insertion port 29 remains long, and it becomes easy to recognize erroneous insertion.

  Even when the second card C2 is inserted with the front end portion 11c facing the insertion slot 29, but with the front surface 11a facing downward, the left side portion 11f and the front end portion of the second card C2 are reversed. Since the vicinity of the boundary with 11c hits the erroneous insertion prevention convex portion 44a, it is easy to recognize erroneous insertion as well.

  That is, in the second card C2, the external connection portion of the second card C2 is connected to the second connection terminal 58 unless the missing portion 16 is inserted in a normal direction facing the erroneous insertion prevention convex portion 44a. It is not inserted until.

  In this type of card connector, when the control unit detects that the external connection portion 5 of the first card C1 is in contact with the first connection terminal 55, the first card C1 is mounted in a normal posture. It is recognized that That is, in this type of card, since any one of the external connection portions 5 is short-circuited in the card, the first card C1 is monitored by monitoring whether or not the predetermined first connection terminals 55 are short-circuited. It can be detected whether or not is mounted in a normal position. The same applies to the second card C2, and whether or not the second card C2 has reached the normal mounting position by monitoring whether or not the predetermined second connection terminals 58 are short-circuited. Can be detected.

  Here, as shown in FIG. 3, when the first card C1 was inserted in the wrong posture and when the second card C2 was inserted in the wrong posture, both were provided on the card. The external connection portion is not normally connected to the first connection terminal 55, or the external connection portion provided on the card is not normally connected to the second connection terminal 58. Therefore, when the first card C1 is inserted in the wrong direction and when the second card C2 is inserted in the wrong direction, the control unit does not determine that the card has been normally inserted.
