Description

  The present invention relates to a card connector to which a card containing an electronic circuit is mounted, and more particularly to a card connector that can prevent insertion of a card other than a regular card.

  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 electrodes are provided on the surface of the case to be electrically connected to an electronic circuit such as an internal memory chip or IC chip.

  A card connector to which this type of electronic function card is mounted includes a slider that moves in the front-rear direction inside the casing, a biasing member that biases the slider toward the insertion slot of the casing, and a rear part of the casing. A lock mechanism for locking the slider moved to the side is provided. As described in Patent Document 1 and the like, the slider is provided with a latching member (latch) that fits into a recess formed in a side portion of the card. When a card is mounted in the housing and the hooking member is fitted in the recess, the slider is moved into the housing by the pushing force of the card and is locked by the lock mechanism. At this time, the connection terminal provided in the housing and the external connection electrode provided on the lower surface of the card are connected.

  This type of card connector is very small and determines whether or not the card is inserted with the touch of a finger. Therefore, the card is inserted in the reverse direction or the reverse direction and inserted into the back of the housing. If the slider is locked, the operator may not understand that the card has been inserted in the wrong direction even though the external connection electrode of the card is not conducted to the connection terminal.

  Therefore, in the card connector described in Patent Document 1 below, a protrusion for preventing erroneous insertion is fixed inside the housing, and the card slides with the protrusion when inserted into the housing. Grooves are provided. When the card is inserted in a normal posture, the groove and the protrusion coincide with each other, and the card can be inserted into the housing. Also, if the card is inserted in a non-normal posture, the position of the groove and the protrusion does not match, so the card cannot be sent to the inside of the housing.

Further, in the card connector described in Patent Document 2 below, when the card is inserted into the housing in a normal posture, the concave portion formed on the side of the card and the latching convex portion provided on the slider are Engage and the card and the slider are combined together to move in the back direction of the housing. On the other hand, when the card is inserted in the wrong posture and the concave portion formed on the card cannot be aligned with the latching convex portion of the slider, the slider is pushed in the direction crossing the insertion direction by the side of the card. The card is locked in the casing, and the card cannot be moved further inward of the casing.

  Since the card connector described in Patent Document 1 has a groove extending in the insertion direction on the surface of the card, it is subject to space restrictions when an IC or the like is placed inside the card connector. It is difficult to maintain design freedom. Moreover, since the groove | channel recessed in the thickness direction is formed in the surface of a card | curd, it is difficult to apply to a card | curd with a thin dimension.

  Further, the card connector described in Patent Document 2 has a structure in which when a card is inserted in the wrong direction, a slider pushed to the side of the card moves in the lateral direction, so that malfunction is likely to occur. For example, even though the card is inserted in a normal posture, the slider is locked in the casing, and the slider is likely to move.

  Moreover, as for the thing described in patent document 2, as long as the slider is not extruded to a horizontal direction, a slider can move to the back | inner side of a housing | casing. That is, the slider is not locked when the card is not inserted, and the slider can be moved into the housing at any time. For this reason, when a card having a width smaller than that of the original card or other foreign objects is inserted, there is a drawback that the slider moves together with these inside the casing.

  Furthermore, the conventional card connector is a structure intended to prevent the insertion of a card that should be received when it is inserted in a wrong posture, such as a reverse direction or a reverse direction. When there are two types of cards having similar shapes, there is no card that adopts a structure that accepts insertion of one of the cards but prevents insertion of the other card.

  The present invention solves the above-described conventional problems, and when a card different from a regular card that should be originally received is inserted, or when the regular card is inserted in an incorrect posture, the insertion is ensured. The object is to provide a card connector that is easy to prevent.

  Another object of the present invention is to provide a card connector capable of accepting insertion of one card and preventing insertion of the other card when two types of cards having similar shapes exist. It is said.

According to a first aspect of the present invention, there is provided a housing having a storage area into which a card containing an electronic circuit is inserted, a slider that is provided inside the housing and moves forward and backward in the insertion direction and the ejection direction of the card, and the slider And a locking mechanism for locking the slider that has been moved in the card insertion direction.
The slider is provided with a detection member capable of moving back and forth toward the storage area and biased in a direction protruding into the storage area.
When the slider is about to move in the card insertion direction with the detection member protruding into the storage area, a restricting portion is provided to restrict the movement of the slider against the detection member, and the storage area When the detection member is pushed into the slider by the side portion of the card inserted into the slider, the detection member can move to a position where the slider is locked by the lock mechanism without hitting the restriction portion. It is characterized by that.

  In the card connector according to the first aspect of the present invention, the slider moves only in the card insertion direction, and a detecting member is movably provided on the slider, and the slider is allowed to move depending on the operating state of the detecting member. Is locked so that it cannot move into the housing. As described above, since the moving direction of the slider is only the linear direction and the detection member mounted on the slider is operated, the moving operation of the slider and the locking operation of the slider can be reliably performed.

  In the card connector of the first aspect of the present invention, the slider is locked when the card is not inserted, and the slider can move only when the regular card is inserted in a normal posture. Therefore, when a card or a foreign object having a too small width is accidentally inserted, the slider does not move toward the back side of the housing, and it is easy to prevent the card other than the normal card from being inserted in a normal posture. .

  According to the present invention, the slider is provided with a stopper portion, and the detection member is pushed into the slider by a side portion of the card until the leading end portion of the card inserted into the storage area hits the stopper portion. It is what

  With the above structure, only when a regular card is normally inserted, the slider can be moved and locked in the rearward direction of the housing by the card insertion force.

According to a second aspect of the present invention, there is provided a housing having a storage area into which a card containing an electronic circuit is inserted, a slider which is provided inside the housing and moves forward and backward in the insertion direction and the ejection direction of the card, and the slider And a locking mechanism for locking the slider that has been moved in the card insertion direction.
The slider is provided with a detection member capable of moving back and forth toward the storage area and biased in a direction protruding into the storage area.
When the detection member is pushed toward the slider and the slider is about to move in the card insertion direction, a restricting portion is provided to restrict the movement of the slider against the detection member, and the storage When the detection member protrudes into a recess formed on the side portion of the card inserted into the area, the detection member does not hit the restricting portion and moves to a position where the slider is locked by the lock mechanism. It is characterized by being made possible.

  The card connector according to the second aspect of the present invention also has a structure in which the slider moves linearly only in the card insertion direction, so that it is difficult for the slider to malfunction. In addition, the slider can be moved to the back side of the housing together with the card only when the concave portion formed on the side portion of the card faces the detection member.

  Also in the second aspect of the present invention, the slider is provided with a stopper portion, and a recess formed in the side portion of the card until the leading end portion of the card inserted into the storage area hits the stopper portion. What the said detection member protrudes in is preferable.

In the first invention and the second invention, it is preferable that the casing has a lid for closing the storage area, and the restricting portion is formed integrally with the lid. It is preferable that a hole or a notch is formed in the lid, and a part of an edge of the hole or the notch is the restricting portion.
In the above configuration, the casing can be configured to be thin.

  Furthermore, the detection member can be configured to be provided with a switch mechanism that switches the detection output between when the detection member protrudes into the storage area and when the detection member is pushed into the slider.

  If the structure is such that the switch mechanism operates according to the position of the detection member, it can always be surely ascertained whether or not a regular card to be received has been inserted normally.

  In the present invention, when a card other than a legitimate card that should be accepted is inserted, or when a legitimate card is inserted in the wrong direction, the insertion can be prevented.

  In the first aspect of the present invention, since the slider is locked when no card is inserted, insertion of a card having a width smaller than that of a regular card or other foreign matter is prevented. It's easy to do.

  Further, according to the present invention, when two types of cards having similar shapes exist, it is possible to insert one of the cards and prevent the other card from being inserted.

Also good.

  As shown in FIGS. 12 to 14, the case 1 has a front end 1c and a rear end 1d. It also has a right side 1e and a left side 1f.

  As shown in FIG. 13, 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. 12, 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. 12, in the plan view of the case 11 viewed from the surface 1a side, the shape of the case 1 is symmetrical to the left and right via a center line OO extending in the front-rear direction.

  In the front portion of the case 1, front concave portions 6 and 6 that are recessed from the right side portion 1 e and the left side portion 1 f toward the center line OO are formed. The front recesses 6 and 6 include inner side surfaces 6a and 6a that are parallel to the right side portion 1e and the left side portion 1f and that are 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 rear 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 front concave portion 6 and the right side portion 1e and between the rear end portion of the left front concave portion 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 the inclined portions 6b and 6b are flat surfaces or curved surfaces having a curvature.

  As shown in FIG. 13, the front recesses 6 and 6 are recessed from the front surface 1 a of the case 1 toward the back surface 1 b. The distance from the front surface 1a of the case 1 to the inner bottom surface 6c of the front concave portion 6, that is, the depth dimension t1 from the front surface 1a to the rear surface 1b of the front concave portions 6, 6 is the total thickness dimension T of the first card C1. It is almost 1/2. Further, as a result of the front recesses 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 T of the first card C1.

  The front concave portions 6 and 6 are opened forward at the left and right side portions of the front end portion 1c. Therefore, as shown in FIG. 14, the thickness dimension of the front end 1c is T at most of the center thereof, but the thickness dimension is t2 on both sides. As shown in FIG. 12, the front and rear length dimensions L1 of the front recesses 6 and 6 are distances from the front end 1c of the case 1 to the rear ends of the inclined portions 6b and 6b.

  On the right side 1e and the left side 1f of the case 1, intermediate recesses 8 and 8 are formed at positions spaced a distance L2 rearward from the rear end portions of the front recesses 6 and 6. A longitudinal dimension L3 of the intermediate recesses 8, 8 is shorter than a longitudinal dimension L1 of the front recesses 6, 6.

  The intermediate 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 from the right side 1e to the inner end 8a in the right intermediate recess 8 and the width dimension W2 from the left side 1f to the front inner end 8b in the left intermediate recess 8 are the width dimension W1 of the front recesses 6 and 6, respectively. Is almost the same.

  The intermediate recesses 8, 8 have a front inner end 8b and a rear inner end 8c, and the distance between the front inner end 8b and the rear inner end 8c is the length dimension L3 of the intermediate recesses 8, 8. is there.

  As shown in FIGS. 13 and 14, the intermediate 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, 8d is the depth dimension t3 of the intermediate recesses 8, 8, and this depth dimension t3 is larger than the depth dimension t1 of the front recess 6. Since the depth dimension t3 of the intermediate recesses 8 and 8 is larger than the depth dimension t1 of the front recesses 6 and 6, the latching portion 49a of the holding leaf spring 49 provided on the slider 40, as shown in FIG. The intermediate recesses 8 and 8 are easy to enter.

  As shown in FIG. 12, 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.

(The shape of the second card)
As shown in FIG. 15, the second card C <b> 2 has a case 11, in which a memory chip and other IC chips are accommodated.

  The front recesses 16 and 16 formed in front of the right side 1e and the front of the left side 1f of the case 11 of the second card C2 are longer than the front recesses 6 and 6 on the left and right sides of the first card C1. The first card C1 and the second card C2 are the same in all other shapes. In other words, the thickness dimension T and the width dimension W0 of the case 11 of the second card C2 and the overall length of the length dimension in the vertical direction are the same as the case 1 of the first card C1. The shape, size, and position of the intermediate recesses 8, 8 formed in the case 11 of the second card C2 are the same as those of the case 1 of the first card C1. In addition, in FIG. 15, the same code | symbol is attached | subjected to the part same as the case 1 of the 1st card | curd C1, and the detailed description is abbreviate | omitted.

  The said front recessed parts 16 and 16 formed in the 2nd card | curd C2 shown in FIG. 15 have the inner surface 16a in the position approaching centerline OO. The position of the inner surface 16a, that is, the width dimension W1 of the front recesses 16 and 16 is the same as the width dimension W1 of the front recesses 6 and 6 of the case 1 shown in FIG. Further, the dimension from the surface 1a of the case 11 to the inner bottom surface 16c of the front recess 16, that is, the depth dimension of the front recesses 16, 16 is the same as the depth dimension t1 of the front recesses 6, 6 of the case 1 shown in FIG. It is. The case 11 of the second card C2 is provided with thin portions 17 and 17 on the back side of the front recesses 6 and 6, and the width and thickness dimensions of the thin portions 17 and 17 are also the first. It is the same as the thin portions 7 and 7 of the card C1.

  However, the length L11 of the front recesses 16 and 16 and the thin portions 17 and 17 of the case 11 shown in FIG. 15, that is, the rear end of the inclined portion 16b located at the rear end of the front recesses 16 and 16 from the front end 1c. The distance L11 is longer than the length L1 of the front recesses 6 and 6 and the thin portions 7 and 7 of the case 1 shown in FIG. The first card C1 and the second card C2 can be distinguished from each other only by the difference between the length dimension L1 of the front recesses 6 and 6 and the length dimension L11 of the front recesses 16 and 16.

  The length dimension L3 of the intermediate recesses 8, 8 formed in the case 11 of the second card C2 is the same as the length dimension L3 of the intermediate recesses 8, 8 of the case 1. Further, the length dimension L11 + L12 shown in FIG. 15 is the same as the length dimension L1 + L2 shown in FIG. That is, the distance from the front end 1c in the case 11 shown in FIG. 15 to the front inner ends 8b, 8b of the intermediate recesses 8, 8 is the same as the distance in the case 1 shown in FIG.

  The number, position and shape of the external connection electrodes appearing on the back surface 1b of the case 11 of the second card C2 are the same as the external connection electrodes 5 appearing on the back surface 1b of the case 1 of the first card C1 shown in FIG. Exactly the same.

  The specifications of the first card C1 and the second card C2 are different. The 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 via the external connection electrode for power supply. Alternatively, the difference in specifications is the difference in memory capacity of the memory chips housed in the cases 1 and 11.

  As shown in FIGS. 12 and 15, the case 1 of the first card C1 and the case 11 of the second card C2 are both symmetrical with respect to the center line OO, and the overall planar shape is It is a rectangle. Therefore, the space inside the cases 1 and 11 can be effectively used widely, and the internal IC chip and other circuits can be integrated and arranged while being small and thin.

  In addition, since the front recess 6 or the front recess 16 and the intermediate recess 8 are recessed only from the surface 1a side of the cases 1 and 11, it is easy to distinguish the front and back of the case. Moreover, since the front recessed part 6 or the front recessed part 16 is formed in the front area in the left and right side parts 1e and 1f, it is easy to distinguish the front and rear of the case.

The hole 55 is a restricting movement part 55a whose portion on the (c) side extends at a short distance from (a) to (b), and whose portion on the (d) side is at a long distance in the (a)-(b) direction. It is the insertion movement part 55b extended. At the edge of the hole 55, a stepped portion is formed at the boundary between the restriction moving portion 55 a and the insertion moving portion 55 b, and this stepped portion serves as the restriction portion 56.

  The width B1 of the restriction moving portion 55a is a size that can hit the selection convex portion 46e formed on the detection member 46. As shown in FIGS. 3A and 3B, when the detection member 46 protrudes in the (c) direction and the slider 40 moves in the (a) direction, the selection convex portion 46e of the detection member 46 becomes the restricting portion. 56, further movement of the slider 40 in the direction (a) is restricted. That is, the movement range of the slider 40 is limited to the range of the restriction movement unit 55a.

  A width dimension B2 of the insertion moving part 55b is larger than a width dimension of the selection convex part 46e. As shown in FIG. 4, when the slider 40 is moved in the (a) direction with the detection member 46 being pushed in the (d) direction, the selection convex portion 46e is elongated in the (a) direction in the insertion moving portion 55b. Can move.

  As shown in FIG. 3A, a holding recess 40b is formed on the upper surface of the slider 40 (on the (b) side), and a holding plate spring 49 is held in the holding recess 40b. Yes. The holding plate spring 49 has a latching portion 49a bent in a mountain shape, and the latching portion 49a projects from the guide surface 41 in the (c) direction. The thickness dimension of the latching portion 49 a is substantially the same as the thickness dimension ta of the guide convex portion 45, and the height position at which the latching portion 49 a projects from the guide surface 41 is the projecting position of the guide convex portion 45. It almost matches.

  As shown in FIG. 4, when the front end portion 1c of the first card C1 hits the stopper portion 44, the hook portion 49a is fitted into the intermediate recess 8 formed on the right side portion of the first card C1. Match. Similarly, as shown in FIG. 6, when the second card C2 is inserted and the front end portion 1c hits the stopper portion 44, the latching portion 49a is formed on the right side portion of the second card C2. The intermediate recess 8 is fitted.

  Between the slider 40 and the housing | casing 21, the locking mechanism 35 for locking the slider 40 in the back | inner side ((a) side) is provided. The lock mechanism 35 includes a groove cam 42 formed on the upper surface of the slider 40 and a lock pin 36 provided on the housing 21.

  The lock pin 36 has a proximal end portion 36a and a distal end portion 36b bent at a right angle. As shown in FIG. 4, the base end portion 36 a of the lock pin 36 is rotatably supported in a holding recess 24 c formed in the upper portion of the front wall portion 24 of the housing body 22. The distal end portion 36 b of the lock pin 36 is slidably inserted into the groove cam 42. As shown in FIG. 1, a lock plate spring 37 is integrally formed on the right front side of the ceiling plate 23a of the lid body 23 formed of a metal plate. The lock leaf spring 37 is a cantilever support spring formed by cutting out a part of the ceiling plate 23a. The lock pin 36 is pressed by the lock plate spring 37, and the tip 36 b is pressed against the groove bottom of the groove cam 42.

  As shown in FIG. 4, the groove cam 42 is located on the back side ((a) side) of the lock release part 42 a and on the front side ((b) side) of the lock release part 42 a. It has a lock part 42b. Between the lock release part 42a and the lock part 42b, a forward groove 42c is formed on the left side, and a return groove 42d is formed on the right side. Inside the groove cam 42, steps are formed at the boundary portions of the lock release portion 42a, the forward groove 42c, the lock portion 42b, and the return groove 42d, and the tip portion 36b of the lock pin 36 is connected to the lock release portion 42a → It is possible to slide only in the order of forward groove 42c → lock portion 42b → return groove 42d → lock release portion 42a, and the reverse process cannot be followed.

  In FIG. 4, the slider 40 is moved to the front side ((b) side) by the urging force of the compression coil spring 51 and is abutted against the front wall portion 24 of the housing body 22. At this time, the distal end portion 36 b of the lock pin 36 is located in the lock release portion 42 a of the groove cam 42. When the selection convex portion 46e moves within the insertion movement portion 55b without being restricted by the restriction portion 56 shown in FIG. 3B, the slider 40 can move to the far side ((a) side). 5, the tip 36b of the lock pin 36 passes through the forward groove 42c of the groove cam 42 and reaches the lock 42b, so that the slider 40 does not return to the front side ((b) side). Locked to.

  Thereafter, when the slider 40 is moved to the back side ((a) side) by a short distance, the tip end portion 36b of the lock pin 36 comes out of the lock portion 42b of the groove cam 42 and is guided toward the return groove 42d. The slider 40 is unlocked. Therefore, the slider 40 returns to the initial position shown in FIG. 4, and during this time, the tip end portion 36b of the lock pin 36 returns from the return path groove 42d to the lock release portion 42a.

  As shown in FIG. 1, a side pressure plate spring 58 is integrally formed on the left side plate 23 d of the lid body 23. As shown in FIG. 4, the side pressure plate spring 58 enters the inside of the housing 21 and is positioned at an upper portion in the storage area of the housing 21.

  As shown in FIG. 4, when the first card C1 is inserted in a normal posture, the side pressure plate spring 58 enters the front concave portion 6 on the left side of the first card C1. Since the side pressure plate spring 58 enters the front concave portion 6 and above the thin portion 7, it is possible to prevent the front portion of the card inserted into the housing 21 from floating from the bottom wall portion 28. As shown in FIG. 5, when the slider 40 is pushed and locked to the back side ((a) side) together with the first card C1, the side pressure plate spring 58 compresses the left side 1f of the first card C1. The first card C1 is pushed in the direction (d). Therefore, the detection member 46 on the slider 40 is surely pushed in the (d) direction by the first card C1, and the selection convex portion 46e provided on the detection member 46 is inadvertently provided to the restriction portion 56. It becomes easy to prevent malfunctions such as being regulated.

  FIG. 11 shows the shape of the bottom wall portion 28 of the housing body 22. A connection terminal 61 is provided on the bottom wall portion 28 on the back side ((a) side). The connection terminals 61 are arranged in the same number and the same pitch as the external connection electrodes 5 exposed on the back surface 1b of the first card C1 shown in FIG. An external terminal 62 is provided on the front side of the bottom wall portion 28. The plurality of connection terminals 61 and the plurality of external terminals 62 are electrically connected one-on-one.

  As shown in FIG. 2, the connection terminals 61 protrude upward from the bottom wall portion 28, and when the first card C <b> 1 is normally mounted to the position shown in FIG. 5, each connection terminal 61 is a first terminal. Connected to the external connection electrode 5 provided on the card C1. The external terminal 62 is soldered to an electrode portion such as a circuit board on which the card connector 20 is mounted.

  As shown in FIG. 11, a switch mechanism 65 is provided on the right side portion of the bottom wall portion 28 of the housing body 22. The switch mechanism 65 is provided with a pair of sliding electrodes 66 and 67 extending in the (a)-(b) direction on the upper surface of the bottom wall portion 28. The two arms 47a and 47b of the torsion compression spring 47 mounted on the slider 40 and biasing the detection member 46 function as contact points, respectively, and both the arms 47a and 47b are bottom wall portions. The upper surface of 28 is repressed.

  As shown in FIG. 4, when the slider 40 is positioned on the front side ((b) side), the arm portions 47 a and 47 b are both disengaged from the sliding electrodes 66 and 67. At this time, the sliding electrode 66 and the sliding electrode 67 are non-conductive. When the slider 40 is pushed and moved in the direction (a), the one arm portion 47 a contacts the sliding electrode 66 and moves on the sliding electrode 66.

  When the detection member 46 protrudes in the (c) direction in the slider 40, when the slider 40 moves in the (a) direction, the arm portion 47b moves on the left side portion away from the sliding electrode 67, and the arm portion 47b. And the sliding electrode 67 do not come into contact with each other. At this time, the sliding electrode 66 and the sliding electrode 67 do not conduct. On the other hand, when the slider 40 moves in the direction (a) while the detection member 46 is pushed in the direction (d), the arm portion 47b slides on the sliding electrode 67, and is made of metal and conductive torsionally compressed. The sliding electrode 66 and the sliding electrode 67 are electrically connected via the spring 47.

  In the control unit, by monitoring the conduction state between the sliding electrode 66 and the sliding electrode 67, when the slider 40 moves in the (a) direction, whether the detection member 46 protrudes in the (c) direction ( d) It is possible to identify whether it is pushed in the direction.

(Normal mounting operation to the card connector 20 of the first embodiment)
When nothing is attached to the card connector 20 of the first embodiment, the slider 40 moves to the insertion port 29 side ((b) side). 3A and 3B, the detection member 46 is moved in the direction (c) on the slider 40 by the urging force of the torsion compression spring 47, and the first inclined surface 46a and the second inclined surface 46a. The surface 46b protrudes from the detection surface 41 on the left side of the slider 40 to the storage area.

  Therefore, it is assumed that a card having a thickness smaller than that of the first card C1, a card having a shorter width, or a foreign object other than the card is inserted from the insertion port 29, and the stopper portion 44 integrated with the slider 40 is pushed by this foreign object. 3B, when the selected convex portion 46e of the detection member 46 moving in the (c) direction moves in the (a) direction by a limited movement range of the restriction moving portion 55a. Then, it hits the regulation part 56. Therefore, the slider 40 does not move in the (a) direction beyond that.

  Further, when the selected convex portion 46 e hits the restricting portion 56, the lock portion 42 b of the groove cam 42 provided on the slider 40 does not reach the position where it is hooked on the tip end portion 36 b of the lock pin 36, and the slider 40 Are not locked by the lock mechanism 35. Therefore, if a card having a thickness smaller than that of the first card C1, a card having a shorter width, or a foreign object other than the card is taken out, the slider 40 is moved in the direction (b) by the urging force of the compression coil spring 51 and is initially Return to position.

  As shown in FIG. 3A, the detection member 46 is provided with a first inclined surface 46a facing in the (b) direction and a second inclined surface 46b facing in the (a) direction. Therefore, when a card or a foreign object having a different shape is inserted or pulled out, the card or the foreign object and the first inclined surface 46a or the second inclined surface 46b slide, so that the card or the foreign object is caught by the detection member 46. There is no.

  As shown in FIG. 11, when the card is not inserted and the slider 40 moves to the (b) side and is in the initial position, the arm portion 47a and the arm portion 47b of the torsion compression spring 47 mounted on the slider 40 are provided. However, both are located on the (b) side of the sliding electrode 66 and the sliding electrode 67 provided on the bottom wall portion 28, and the sliding electrode 66 and the sliding electrode 67 are not conductive.

  As shown in FIG. 3B, when the slider 40 is slightly moved in the direction (a) and the selected convex portion 46e hits the restricting portion 56, the arm portion 47a shown in FIG. The sliding electrode 66 and the sliding electrode 67 are not electrically connected to each other. Therefore, when the card thinner than the first card C1, a card having a shorter width, or other foreign matter is inserted and the stopper portion 44 is pushed, the first card C1 is normally mounted from the switch mechanism 65. Can prevent the same detection output from being generated.

4 and 5 show the operation when the first card C1 is mounted in the normal orientation.
As shown in FIGS. 2 and 4, 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 thin-walled portion 7 formed on the right side of the case 1 of the card C1 passes under the latching portion 49a of the holding leaf spring 49 provided on the near side of the slider 40 shown in FIG. Further, it passes below the detection member 46 and the guide protrusion 45 that protrude into the storage area. The latching portion 49a of the holding leaf spring 49 slides on an inclined portion 6b formed at the rear end of the front concave portion 6 on the right side of the first card C1, and is deformed in the (d) direction. Furthermore, the latching part 49a slides on the right side 1e of the first card C1, and when the front end 1c of the first card C1 hits the stopper part 44, the latching part 49a is in contact with the first card C1. And the first card C1 and the slider 40 are temporarily fixed.

  Further, immediately before the front end portion 1c of the first card C1 hits the stopper portion 44 of the slider 40, the first inclined surface 46a of the detection member 46 slides the inclined portion 6b behind the front concave portion 6 of the first card C1. As shown in FIG. 4, when the front end portion 1c hits the stopper portion 44, the right side portion 1e of the first card C1 presses the detection member 46 in the direction (d), and the detection member 46 It is pushed into the slider 40 against the torsion compression spring 47.

  As shown in FIG. 4, when the first card C1 is pushed into the housing 21 in a state where the first card C1 is temporarily fixed to the slider 40 by the latching portion 49a, the first card C1. The stopper portion 44 is pushed by the front end portion 1c, and the slider 40 moves in the direction (a). At this time, since the detection member 46 is pushed in the (d) direction, the selection convex portion 46e provided on the detection member 46 moves to the insertion movement portion 55b side of the hole 55 shown in FIG. ing. Therefore, when the slider 40 moves in the (a) direction, the selection convex portion 46 e moves in the (a) direction within the insertion moving portion 55 b without hitting the restricting portion 56.

  Therefore, as shown in FIG. 5, the first card C <b> 1 and the slider 40 are moved to the depth direction of the housing 21, and the lock portion 42 b of the groove cam 42 formed on the slider 40 is the tip of the lock pin 36. The slider 40 is locked to the position 36b and locked at that position.

  At this time, as shown in FIG. 11, each of the connection terminals 61 provided on the back side of the housing body 22 is exposed to the back surface 1b of the first card C1, as shown in FIG. Repressed and connected to each of the.

  When the first card C1 is inserted in a normal posture, the detection member 46 shown in FIG. 11 is pushed in the (d) direction, so that the arm portion 47b of the torsion compression spring 47 is pushed in the (d) direction. Therefore, when the slider 40 moves in the direction (a) together with the first card C1, one arm portion 47a of the torsion compression spring 47 comes into contact with and slides on the sliding electrode 66 at the bottom of the housing 21. The other arm portion 47 b also slides in contact with the sliding electrode 67. Therefore, the sliding electrode 66 and the sliding electrode 67 are electrically connected by the torsion compression spring 47, and the control unit recognizes that the first card C1 is normally loaded.

  When the first card C1 is detached from the card connector 20, as shown in FIG. 5, the first card C1 is pushed to the back side ((a) side) from the normally mounted state. When the slider 40 moves slightly back together with the first card C1, the distal end portion 36b of the lock pin 36 is disengaged from the lock portion 42b of the groove cam 42, and the slider 40 is moved forward ((b ) Side). Therefore, as shown in FIG. 2, the slider 40 returns to the initial position, and the rear end portion of the first card C <b> 1 is protruded from the insertion slot 29.

(Abnormal mounting operation to the card connector 20 of the first embodiment)
As shown in FIGS. 12 to 14, the first card C1 and the second card C2 are substantially the same in overall shape and size. However, when the drive voltages of the first card C1 and the second card C2 are different, the dedicated card connector 20 of the first card C1 and the dedicated card connector 70 of the second card C2 are used separately. May be necessary. In this case, it is necessary to prevent a different card from being inserted into the card connector.

  As described above, the card connector 20 of the first embodiment is mounted only for the first card C1, and has a function of preventing the second card C2 from being mounted. Yes.

  FIG. 6 shows an operation when the second card C2 shown in FIG. 15 is inserted into the card connector 20 of the first embodiment. In FIG. 6, the second card C2 is inserted in such a posture that the front end 1c is directed to the back side of the housing 21 and the surface 1a is directed upward. At this time, the thin portion 17 provided on the right front side of the second card C2 can enter under the guide convex portion 45 shown in FIG. 3A, and the front end portion 1c of the second card C2 is the stopper. The latching portion 49 a hits the portion 44 and fits into the intermediate recess 8, so that the second card C 2 is temporarily secured to the slider 40.

  However, since the second card C2 has a length L11 from the front end 1c of the front recess 16 longer than that of the first card C1, when the front end 1c hits the stopper portion 44, the detection member 46 is detected. Is a state protruding into the front recess 16.

  Therefore, when the second card C2 is pushed into the back side of the housing 21 from the state of FIG. 6 and the slider 40 is moved, the selection provided on the detection member 46 is shown in FIG. The convex part 46e moves in the regulation movement part 55a of the hole 55, the selection convex part 46e hits the regulation part 56, and it can prevent that the slider 40 and the 2nd card | curd C2 are inserted further back.

  Since the slider 40 is not locked by the lock mechanism 35 when the selected convex portion 46e hits the restricting portion 56, when the pressing force to the second card C2 is released, the biasing force of the compression coil spring 51 causes the first The second card C2 and the slider 40 are returned to the insertion slot 29.

  Therefore, when the user mistakenly installs the second card C2 instead of the first card C1, the second card C2 cannot be pushed into the housing 21 and protrudes from the insertion slot. Therefore, it can be easily recognized that the second card is erroneously inserted.

  When the first card C1 is inserted into the card connector 20 in the reverse direction or the reverse direction, the side portion of the tip portion on the insertion side hits the guide convex portion 45 of the slider 40, and the first card Since the card C1 cannot be inserted to the position where it hits the stopper portion 44, the user can easily understand that the card C1 is erroneously inserted.

(Structure of the card connector 70 of the second embodiment)
FIG. 7 shows a part of the card connector 70 according to the second embodiment.

  In the card connector 70 of the second embodiment, the shape of the hole (or notch) 155 opened on the slider 40 in the ceiling plate 23a of the lid 23 is shown in FIG. This is different from the shape of the hole 55 of the card connector 20 of the first embodiment. However, except for the structure of the hole portion 155, the structure of each part of the card connector 70 of the second embodiment is exactly the same as the structure of each part of the card connector 20 of the first embodiment. Therefore, in the card connector 70 of the second embodiment shown in FIGS. 7 to 10, the same reference numerals as those used in the description of the card connector 20 of the first embodiment are attached to the components other than the hole 155. Detailed description thereof will be omitted.

  As shown in FIG. 7, the shape of the hole 155 formed in the ceiling board 23a is bilaterally symmetric with the hole 55 shown in FIG. The regulation moving portion 155a having the width dimension Ba is formed on the (d) side, and the insertion moving portion 155b having the width dimension Bb is formed on the (c) side, that is, the storage area side. A restriction portion 156 is provided at the boundary between the restriction movement portion 155a and the insertion movement portion 155b.

  The length of the restriction moving portion 155a in the (a)-(b) direction is the same as the length of the restriction moving portion 55a shown in FIG. 3B, and the length of the insertion moving portion 155b is also shown in FIG. It is the same as the length of the insertion moving part 55b shown.

  In the card connector 70 of the second embodiment, as shown in FIG. 8, when the detection member 46 protrudes from the slider 40 in the direction (c), the selection convex portion 46e provided on the detection member 46 is The inside of the insertion movement part 155b of the hole part 155 can be moved. Therefore, the slider 40 moves to the back of the housing 21 and is locked by the lock mechanism 35.

  As shown in FIG. 10, when the detection member 46 is pushed into the slider 40, the selection convex portion 46 e provided on the detection member 46 moves into the restriction moving portion 155 a of the hole portion 155. Therefore, when the slider 40 moves a little in the direction (a), the selected convex portion 46e hits the restricting portion 156, and the slider 40 cannot move to a position where it can be locked by the lock mechanism 35.

(Normal mounting operation to the card connector 70 of the second embodiment)
The card connector 70 of the second embodiment is dedicated to the mounting of the second card C2, and has a function of preventing the mounting of the first card C1.

  As shown in FIG. 8, when the second card C2 is inserted in a normal posture with the front end portion 1c facing forward and the surface 1a facing upward, the right thin portion 17 is located below the latching portion 49a. , And further enters the lower guide portion 41a below the detection member 46 and the guide convex portion 45. When the front end portion 1c of the second card C2 hits the stopper portion 44 integral with the slider 40, the latching portion 49a of the holding leaf spring 49 is fitted into the intermediate recess 8 of the second card C2.

  However, as shown in FIG. 8, since the second card C2 has a large length L11 of the front recess 16, the detection member 46 projects into the front recess 16 when the front end 1c hits the stopper 44. ing. Therefore, as shown in FIG. 7, when the selection convex part 46e provided in the detection member 46 is located in the insertion movement part 155b of the hole 155, the slider 40 is pushed together with the second card C2. The selection convex portion 46e moves in the insertion moving portion 155b and is moved to a position where the slider 40 is locked by the lock mechanism 35 as shown in FIG.

  When the slider 40 is locked, the connection terminal 61 provided on the bottom wall portion 28 of the housing body 22 is connected to the external connection electrode provided on the back surface of the second card C2.

(Abnormal mounting operation to the card connector 70 of the second embodiment)
FIG. 10 shows a state in which the first card C1 is inserted into the card connector 70 of the second embodiment.

  When the first card C1 is mounted in a normal posture with the front end portion 1c facing forward and the surface 1a facing upward, the first card C1 comes into contact with the stopper portion 44 of the slider 40 when the first card C1 hits the stopper portion 44. The detection member 46 is pushed in the direction (d) by the right side 1e of C1. Therefore, the selection convex portion 46e provided on the detection member 46 moves into the restriction moving portion 155a of the hole portion 155. Therefore, when the slider 40 is pushed in the direction (a) together with the first card C1, the selection convex portion 46e hits the restricting portion 156, and the slider 40 cannot be inserted to the position locked by the lock mechanism 35.

  Therefore, when the first card C1 is mistakenly inserted into the card connector 70 to which the second card C2 is to be attached, the erroneous insertion can be easily understood immediately.

  Even when the second card C2 is mounted on the card connector 70 in the reverse direction or the reverse direction, the detection member 46 is pushed in the direction (d) by the side portion of the card, so that the slider 40 (a ) Can be prevented from being inserted to the back in the direction and locked by the lock mechanism 35.

  A switch mechanism 65 shown in FIG. 11 is mounted on the card connector 70 of the second embodiment. However, in the second embodiment, it is preferable that the sliding electrode 66 and the sliding electrode 67 extend slightly longer in the (b) direction than in the first embodiment.

  In this case, when the slider 40 is moved in the (b) direction and is in the initial position, the arm portion 47a and the arm portion 47b of the torsion compression spring 47 are both (b) more than the sliding electrode 66 and the sliding electrode 67. The sliding electrode 66 and the sliding electrode 67 are in a non-conductive state.

  As shown in FIGS. 8 and 9, when the second card C2 is normally mounted, when the slider 40 moves in the direction (a), one arm portion 47a of the torsion compression spring 47 slides. While sliding on the moving electrode 66, the other arm 47b does not hit the sliding electrode 67 but moves on the left side. Therefore, when the second card C2 is normally mounted, the sliding electrode 66 and the sliding electrode 67 are in a non-conductive state.

  On the other hand, as shown in FIG. 10, when the first card C1 is inserted into the card connector 70 or the second card C2 is inserted in a reverse orientation or a reverse orientation, the detection member 46 (d ) Direction, the selected convex portion 46e hits the restricting portion 56, and the movement of the slider 40 in the (a) direction is restricted. In this case, when the slider 40 moves to a position where the selected convex portion 46 e hits the restricting portion 56, the arm portion 47 a contacts the sliding electrode 66 and the arm portion 47 b contacts the sliding electrode 67. In this way, the sliding electrode 66 and the sliding electrode 67 are electrically connected via the torsion compression spring 47 only when the card connector 70 malfunctions and the movement of the slider 40 is restricted. In the control unit, when the sliding electrode 66 and the sliding electrode 67 are conductive, it can be recognized that an erroneous insertion operation has been performed, and for example, the current supply to the voltage unit of the connection terminal 61 can be stopped. It becomes possible.
