Description

  The present invention relates to a memory card connector for connecting a memory card accommodated in a card accommodating portion to an electronic device, and more specifically, a memory card is inserted between a case main body and a cover rotatably supported by the case main body. The present invention relates to a connector for a memory card that is positioned in a receiving portion.

  Conventionally, the cover that can be rotated with respect to the case body is opened, the memory card is accommodated in the card accommodating portion of the case main body, and then the cover is closed and closed so as to cover the upper surface of the memory card accommodated in the card accommodating portion. A memory card connector that locks the rotation of the cover in a state is known. The memory card housed in the card housing part is positioned between the locked cover and the case body in such a state that the contact from the case body to the card housing part is electrically connected to the conductive pad on the bottom surface of the memory card. As a result, the memory card will not inadvertently vibrate or come out of the card compartment while being electrically connected.

  In the memory card connector having such a configuration, the cover that is closed so as to cover the upper surface of the memory card is opened with respect to the case body from the open position where the cover is rotatable with respect to the case body to insert the memory card. The cover is slid to the lock position to lock the rotation of the cover closed at the lock position (Patent Document 1).

  FIGS. 12 to 14 show a memory card connector 100 having a structure in which the cover slides, and a card frame in which a large number of contacts 102 are faced by standing side frames 101 along both sides. A case main body 103 made of an insulating resin in which a portion 103 a is formed, and a pivot 105 inserted into a bearing hole 104 drilled in front of the side frame 101 (to the right in FIG. 14) project. It consists of a hinge cover 106 that rotates.

  The bearing hole 104 has a long groove 104b whose front is the longitudinal direction and a rear side thereof is formed in a keyhole-like contour with a circle 104a. On the other hand, the pivot 105 inserted into the bearing hole 104 is as shown in FIG. The outline of the cross section is an oval shape that is loosely fitted in the long groove 104b, and the width in the longitudinal direction is slightly shorter than the diameter of the circle 104a. Therefore, the hinge cover 106 is pivotable with respect to the case body 103 at the open position (FIG. 13) where the pivot 105 is located behind the bearing hole 104, and closes the hinge cover 106 that covers the upper surface of the case body 103. In this posture, the pivot 105 can move in the long groove 104 a, and the pivot 105 can slide to the lock position (FIG. 14) at the front position of the bearing hole 104.

  On the side frame 101 of the case main body 103, an upper lock fitting 107 formed integrally with the case main body 103 protrudes from the outer surface of the side frame 101. Both side surfaces of the hinge cover 106 slide along the outer surface of the side frame 101, and a lower lock piece 108 formed in an L shape toward the front is formed. As shown in FIG. 13, the lower lock piece 108 is an open position where the hinge cover 106 is rotatable, is located behind the upper lock fitting 107, and engages below the upper lock fitting 107 at a lock position that slides forward. It is formed in the position to do.

  When the memory card 110 is inserted into the memory card connector 100, as shown in FIG. 12, the memory card 110 is inserted into the rear frame portion 106a of the hinge cover 106 opened at the open position and temporarily held. As shown in FIG. 13, the hinge cover 106 is rotated until it becomes horizontal, and is closed so as to cover the upper surface of the case main body 102.

  In this state, the pivot shaft 105 of the hinge cover 106 can be moved in the front-rear direction in accordance with the direction of the long groove 104b. Therefore, the hinge cover 106 is slid forward, and the pivot shaft 105 becomes the front end position of the bearing hole 104. Move to the lock position shown in. When the hinge cover 106 is slid forward, the lower lock piece 108 moves below the upper lock fitting 107, and both engage with each other at the lock position to restrict the rotation of the hinge cover 106. In the locked position, the contacts 102 corresponding to the respective conductive pads of the memory card 110 sandwiched between the hinge cover 106 and the case main body 103 and positioned and supported in the card accommodating portion 103a are elastically contacted to be electrically connected.

  When removing the memory card 110, the hinge cover 106 is slid rearward in the reverse order described above to the open position, and the hinge cover 106 is opened and removed.

JP 2008-287919 A

  In the memory card connector 100, in order to slide the lower lock piece 108 in the horizontal direction and engage with the lower surface of the upper lock fitting 107, the bearing hole 104 has a circular hole 104a at the rear and a keyhole-shaped contour with a long groove 104b at the front. The hinge cover 106 is slidable in a closed state, but there is play between the long groove 104b and the pivot shaft 105 in a flat posture, so that the hinge cover 106 is inclined slightly from the horizontal. Can be slid from the open position to the locked position.

  If the hinge cover 106 is moved to the lock position due to such an erroneous operation, the lower lock piece 108 is above the upper lock fitting 107 and they are not engaged with each other, so the hinge cover 106 is forcibly opened upward. In this case, the pivot 105 or the long groove 104b is damaged. Also, if the hinge cover 106 is forcibly closed and locked, the lower lock piece 108 may come into contact with the upper lock fitting 107 from above, and either the lower lock piece 108 or the upper lock fitting 107 may be damaged. is there.

  Therefore, the upper lock fitting 107 is formed by processing a metal plate that is not easily damaged apart from the case body 103 made of an insulating synthetic resin, but the upper lock fitting 107 protrudes from the side surface of the side frame 101. A person's finger touched it, causing injury.

  Further, in order to obtain a predetermined strength, the pivot 105 needs to have a length in the short direction of the vertical cross section of a certain length or more, and since the cross section has an oval shape, the length in the long direction is also short. It is necessary to lengthen according to the length. As a result, the inner diameter of the circular shape 104a of the bearing hole 104 is enlarged with respect to the pivotal axis of the circular cross section, which is an obstacle for reducing the height of the memory card connector 100.

  The present invention has been made in consideration of such conventional problems, and even if it is erroneously operated, the pivot support portion of the pivot shaft and the bearing hole and the lock portion that restricts the rotation of the cover may be damaged. The purpose is to provide a connector for memory cards that are not.

  It is another object of the present invention to provide a memory card connector capable of reducing the vertical width of the bearing hole and reducing the height.

In order to achieve the above object, according to the first aspect of the present invention, a card accommodating portion for accommodating a memory card is formed between side frames standing along both sides, and the card accommodating portion is opposed to the side frame via the card accommodating portion. A case body in which an oval bearing hole having a horizontal direction as a longitudinal direction is formed in a portion to be operated, a pivot shaft is inserted into the bearing hole, and an open position where the pivot shaft is located on one side of the bearing hole in the horizontal direction and the other side And a cover that can slide along the side frame across the card receiving recess. The cover is supported in an open position so as to be rotatable about the pivot axis with respect to the case body. In this position, the upper surface of the lower lock portion of the cover comes into contact with the lower surface of the upper lock portion formed on the side frame, and the rotation with respect to the case body is restricted. This is a leaky connector, and the bearing hole of the side frame is formed with a contour that allows the pivot to turn on either one side or the other side in the horizontal direction, and the upper lock part is a cover that turns in the open position. It is formed on the side frame along the movement locus of the lower lock part of the cover that slides across the card receiving recess from the open position to the lock position without interfering with the lower lock part of the cover, and from the open position to the lock position under normal operation The upper surface of the lower lock part of the cover that has been slid in a horizontal posture is brought into contact with the lower surface of the upper lock part, and the upper surface of the upper lock part of the part where the lower lock part comes into contact at the lock position It becomes an inclined surface for guiding the upper face of the locking portion to the lower surface of the upper locking portion, in an erroneous operation, open positions Luo forcibly closed by rotational operation in the direction left slide operation to cover an uncovered to lock position, the upper surface of the lower locking portion of the cover, the most major memory card connector to abut the lower surface of the upper locking portion Features.

  The bearing hole is formed with a contour that allows the pivot to turn on either the horizontal side or the other side, so the cover can turn about the pivot relative to the case body even in the locked position. Even if the cover slid to the lock position where the lower lock portion is located above the upper lock portion is rotated in the opening direction, no load is applied to the pivot and the bearing hole.

  Also, if the cover that has been slid to the lock position where the lower lock part is positioned above the upper lock part is forcibly rotated in the closing direction due to an erroneous operation, the lower lock part of the cover will be inclined on the upper surface of the upper lock part. And is guided to the same locking position as in normal operation, and a large load is not applied to either the lower lock portion or the upper lock portion.

  The cover closed in the horizontal direction so as to straddle the card receiving recess in the open position is guided by the upper locking part formed along the movement locus of the lower locking part moving in the horizontal direction until it reaches the lock position. It moves and is reliably guided to a position where the upper surface of the lower lock portion comes into contact with the lower surface of the upper lock portion.

  According to the second aspect of the present invention, the side frame of the portion where the upper lock portion is formed is formed by folding the upper part of the band-shaped metal plate standing in the horizontal direction as the longitudinal direction into a downward U-shape. A character-shaped tip surface is a lower surface of the upper lock portion, and an outer surface folded back in a U-shape is an upper surface of the upper lock portion.

  Since the upper lock portion is formed by bending the metal plate, sufficient strength is obtained, and the upper end becomes a downward U-shaped curved surface, so that the cut surface of the metal plate does not appear on the upper surface of the side frame.

  In the invention according to claim 3, the side frame of the part where the bearing hole is formed is formed by folding the upper part of the band-shaped metal plate standing in the horizontal direction as a longitudinal direction into a downward U-shape. The outer surface that is folded back is an inclined surface that guides the pivot that abuts from above to the bearing hole.

  Since the side frame where the bearing hole is formed is formed by folding the upper part of the belt-like metal plate downward U-shaped, the cut surface of the metal plate does not appear on the upper surface of the side frame.

  The side frame of the part where the bearing hole is formed is formed by folding the upper part of the standing conductive metal plate downwardly into a U-shape. Therefore, when the pivot is pushed down from above, the side frame comes into contact with the outer surface of the downward U-shape. The conductive metal plate standing upright bends and the pivot is guided in the bearing hole.

  According to a fourth aspect of the present invention, an upright support piece is integrally connected to one end in the longitudinal direction of the standing band-shaped metal plate, and the upright support piece is attached to the band-shaped metal plate in which a pivot is inserted into a bearing hole. On the other hand, it is bent at right angles to the insertion direction of the pivot.

  The standing support piece is bent at a right angle with respect to the belt-like metal plate standing in the insertion direction of the pivot, so that the belt-like metal plate in which the pivot is inserted into the bearing hole is supported by the standing support piece and is not inclined in the insertion direction of the pivot. .

  The invention according to claim 5 is characterized in that the standing support piece is soldered to the ground pattern of the printed wiring board on which the case main body is arranged.

  By fixing the standing support piece to the printed wiring board on which the case main body is disposed by soldering, the band-shaped metal plate in which the bearing hole is formed is supported more firmly.

  When the upright support piece is soldered to the ground pattern, the side frame made of a band-shaped metal plate integrated with the upright support piece becomes a ground potential.

  According to the first aspect of the present invention, even when the cover is in the locked position, the cover is freely rotatable with respect to the case body. Therefore, the unlocked cover in which the lower lock portion is positioned above the upper lock portion due to an erroneous operation is provided. Even if it is rotated in the opening direction, the pivot and bearing hole will not be damaged.

  On the other hand, the cover that has been slid to the lock position in the unlocked state can be forced to rotate in the closing direction to lock the rotation of the cover in the same manner as normal operation without damaging the lock portion. Accordingly, the upper lock portion protruding from the side frame can be formed of an insulating resin that does not require relatively high strength, and there is no risk of injury.

  Further, since the pivot can be a circular cross section having a diameter shorter than the longitudinal width having an oval cross section, the longitudinal width of the bearing hole can be reduced to reduce the height of the case body.

  According to the invention of claim 2, since the side frame in which the upper lock part is formed is formed by folding the upper part of the metal plate downward U-shaped, the edge of the metal plate is not exposed and has a predetermined strength. There is no risk of injury if you touch your finger while keeping it.

  Since the upper part of the band-shaped metal plate that stands up with the horizontal direction as the longitudinal direction is folded downward U-shaped to form the upper lock part, the upper lock part formed on the side frame along the movement locus of the lower lock part is Can be easily formed simply by bending.

  According to the invention of claim 3, since the side frame on which the bearing portion is formed is formed by folding the upper part of the metal plate downward U-shaped, the edge of the metal plate is not exposed and maintains a predetermined strength. However, there is no risk of injury if a finger touches it.

  Since the pivot is inserted into the bearing hole simply by pressing the pivot from above the side frame on which the bearing portion is formed, the cover can be easily assembled to the case body.

  According to the fourth aspect of the present invention, the upright support piece is bent at a right angle in the insertion direction of the pivot with respect to the upright strip-shaped metal plate, and therefore the strip-shaped metal plate after the pivot is inserted into the bearing hole is supported upright. Even if the side frame receives an unintended external force, the pivot does not come out of the bearing hole.

  According to the fifth aspect of the present invention, the upright support piece is fixed to the printed wiring board on which the case main body is disposed by soldering, so that the pivot is more reliably prevented from being removed from the bearing hole.

  Since the side frame that covers the side of the memory card via the standing support piece soldered to the ground pattern is at the ground potential, the memory card has a shielding function that blocks the memory card from external noise. Further, if the cover that contacts the side frame with the pivot and the lower lock portion is formed of a conductive metal plate, the upper surface side of the memory card is also covered with the ground potential cover, so that the memory card can be shielded more reliably.

  A memory card connector 1 according to an embodiment of the present invention will be described below with reference to FIGS. In the description of each part of the memory card connector 1, in FIG. 1B, the vertical direction is the vertical direction, the right is the front, and the left is the rear. The memory card connector 1 includes a case main body 3 shown in FIG. 4A, a large number of contacts 9 attached to the case main body 3, and a cover 2 shown in FIG. Consists of

  As shown in FIG. 4A, the case main body 3 further includes a metal frame 32 formed by bending a metal plate into a rectangular frame shape surrounding the outer periphery of the memory card 110 to be mounted from above, and a metal frame. And a rectangular plate-like insulating base 31 fixedly attached to the inner side surrounded by 32. Therefore, the card accommodating portion 10 for accommodating the memory card 110 is formed between the side frames 32A standing on both sides along the front-rear direction of the metal frame 32, and the insulating base 31 is disposed on the bottom surface of the card accommodating recess 10. .

  Eight contacts 9 are integrally fixed to the insulating base 31 by insert molding, and window holes or notches are formed at the positions of the contact portions and the leg portions of the respective contacts 9. As a result, the contact portion of each contact 9 faces the card accommodating portion 10 from the window hole and elastically contacts a conductive pad (not shown) of the memory card 110 accommodated in the card accommodating portion 10. The leg portions are solder-connected to the corresponding signal patterns of the printed wiring board 15, and a window hole or a notch is formed to visually confirm the solder connection portion from above.

  In the metal frame 32, case lock portions 8 corresponding to upper lock portions are formed at two locations on both side frames 32A. The side frame 32A at the portion where the case lock portion 8 is formed is shown in FIG. (B) As shown in FIG. 4 (a), the upper part of the belt-like side plate portion that stands up in the front-rear direction is formed by folding it back outwardly in a U-shape. In this way, by folding the upper part of the belt-like side plate portion downwardly into a U-shape, the case-lock portion 8 in which the U-shaped tip surface is the lower surface 8a and the outer surface folded back in the U-shape is the upper surface 8b Formed along.

  Case lock portions 8 formed at two locations on the side frame 32A are located above the movement locus of the cover lock portion 6 that moves along the side frame 32A when the cover 2 slides from an open position to a lock position, which will be described later. Is formed at a portion where the lower surface 8a is disposed. As shown in FIG. 1B, between the case lock portions 8 formed at the front and rear of the side frame 32A, a band-shaped side plate portion on which a U-shaped band-shaped moderation piece 12 that faces downward is raised. Cantilevered integrally with the upper end.

  In addition, the belt-like side plates that stand near the front ends of the side frames 32A on both sides are formed with bearing holes 4 that rotatably and slidably support the cover 2, and the side frames 32A at the portions where the bearing holes 4 are formed. As shown in FIGS. 4 (a) and 4 (b), the upper part of the belt-like side plate portion is folded in a downward U-shape toward the inside. By folding the upper part downward in a U-shape, the strength of the side frame 32A at the portion where the bearing hole 4 is formed is increased. Further, as will be described later, the U-shaped outer side surface of the pivot shaft 5 of the cover 2 4 to facilitate the assembly of the cover 2 to the case body.

  The bearing hole 4 is an oval whose longitudinal direction is the front-rear direction in which both sides of the equal-width long groove are semicircular, and the lower part of the center communicates with a notch in the bottom plate portion of the metal frame 32. . The bottom plate portion of the metal frame 32 is cut out below the bearing hole 4 so that the positioning piece 11 protrudes outward from the bottom plate portion of the metal frame 32 as shown in FIG. The tip of the positioning piece 11 is bent at a right angle upward to face the substantially central position of the bearing hole 4.

  At the front end of the belt-like side plate portion in which the bearing hole 4 is formed, a rectangular upright support piece 7 is continuously provided integrally therewith in front of it. As shown in FIG. 9, the upright support piece 7 is inserted into the bearing hole 4 after the pivot shaft 5 of the cover 2 is inserted, and then the insertion direction of the pivot shaft 5 with respect to the belt-like side plate portion standing in the front-rear direction, that is, the present embodiment. Then, it is bent inward at a right angle and soldered to the ground pattern 16 of the printed wiring board 15 on which the memory card connector 1 is mounted.

  As shown in FIG. 5A, the cover 2 is formed by bending a single conductive metal plate into a U-shaped cross section, and covers the upper portion of the card housing portion 10; It consists of a pair of side covers 2b that are suspended from both sides along the front-rear direction and slide along the outside of the side frame 32A of the case body 3. The side cover 2b protrudes slightly forward from the cover body 2a, and an annular pivot 5 shown in FIG. 5 (b) is formed integrally with the protruding front part. The outer diameter of the pivot 5 is slightly shorter than the vertical width of the bearing hole 4 so as to be loosely inserted into the bearing hole 4 on the case body 3 side. Accordingly, when the pivot shaft 5 is inserted into the bearing hole 4, the pivot shaft 5 is slidable in the front-rear direction between the open position at the front end of the bearing hole 4 and the lock position at the rear end. It can be rotated around the pivot 5 at any position of the lock position.

  Cover lock portions 6 corresponding to the lower lock portions are formed at two positions of each side cover 2b. The cover lock portion 6 is formed by notching the side cover 2b in a gate-shaped U-shape and cutting and raising a rectangular piece having the notch as an outline inwardly upward. The front end surface bent in a crank shape becomes the upper surface 6 a of the cover lock portion that engages with the lower surface 8 a of the case lock portion 8. As shown in FIG. 2 (b), the cover lock portion 6 is formed at the front position of the case lock portion 8 when the cover 4 is closed at the open position where the pivot 4 is located at the front end of the bearing hole 4. Even when the cover 2 in the open position is rotated, the case lock portion 8 is formed at a portion where it does not come into contact.

  Also, bosses 13 projecting inward are formed in the middle of the cover lock portions 6 formed at two locations of each side cover 2b. The boss 13 is placed on the inner side surface of the side cover 2b that gets over the band-shaped moderation piece 12 on the side frame 32A side when the cover 2 covers and closes the card housing portion 10 and slides between the open position and the lock position. It is formed.

  The above-described cover 2 has a pair of pivot shafts 5 projecting inward from the facing position of the side cover 2b, as shown in FIG. 8, from the upper side of the side frame 32A where the bearing holes 4 are formed. It is pushed down in the direction of and assembled to the case body 3. Since the upper part of the belt-like side plate portion in which the bearing hole 4 is formed is folded back downwardly in a U-shape, the pivot 5 comes into contact with the curved outer surface and the belt-like side plate portion bends inward, whereby the pivot 5 is It is guided to be inserted into the bearing hole 4. The upright support piece 7 is on an extended surface of the belt-like side plate portion so that the belt-like side plate portion bends inward during the assembly, and after the pivot shaft 5 is inserted into the bearing hole 4, it is bent at a right angle.

  The memory card connector 1 with the cover 2 attached to the case body 3 is soldered to the signal land pattern on the printed circuit board 15 on which the signal land pattern for electrically connecting the memory card 110 is formed. And implement. At this time, the ground pattern 16 is printed on the surface of the printed wiring board 15 facing the upright support piece 7 bent at a right angle to the bottom plate portion of the metal frame 32, so that a plurality of places on the bottom plate portion and the upright support piece 7 are formed. Is soldered to the ground pattern 16. As a result, the metal frame 32 surrounding the card housing portion 10 and the cover 2 in which the pivot 5 and the cover lock portion 6 are in contact with the metal frame body 32 are also at ground potential, and the memory card 110 housed in the card housing portion 10. Nearly the entire periphery of the is shielded. Further, since the upright support piece 7 is fixed to the surface of the printed wiring board 15, the belt-like metal plate in which the bearing hole 4 is formed is not easily bent inward, and even if the cover 2 receives an unintended external force, the pivot 5 is The bearing hole 4 does not come off.

  Hereinafter, an operation of mounting the memory card 110 on the memory card connector 1 configured as described above will be described in the order of FIGS. When mounting the memory card 110, first, the pivot 5 of the cover 2 is moved to the front end of the bearing hole 4 to open the cover 2 in the open position as shown in FIGS. 1 (a) and 1 (b). The memory card 110 is placed in the card storage unit 10. The periphery of the memory card 110 accommodated in the card accommodating portion 10 is positioned by the metal frame 32, and each conductive pad exposed on the bottom surface comes into contact with the contact portion of the contact 9 facing inside the card accommodating portion 10.

  Since the cover 2 is pivotable around the pivot 5 at the open position, the cover 2 is then horizontally covered with the cover body 2a covering the surface of the memory card 110 as shown in FIGS. 2 (a) and 2 (b). Rotate until The pivot 5 in the open position is positioned at the front open position because the tip of the positioning piece 11 facing the bearing hole 4 from the rear is positioned at the front open position. Does not rattle back and forth. Further, when the cover 2 is in the open position, the cover lock portion 6 is formed at a position that does not interfere with the case lock portion 8 even if the cover 2 is rotated. Therefore, the cover 2 is rotated to a horizontal position. However, it does not contact the case lock portion 8 and is located in front of the case lock portion 8 (see FIGS. 2B and 7).

  With the cover 2 closed, the pivot 5 can move over the positioning piece 11 and move backward in the bearing hole 4, and the case lock portion 8 is formed immediately behind the cover lock portion 6. When the cover 2 is moved horizontally rearward, the upper surface 6a of each cover lock portion 6 is guided by the lower surface 8a of the case lock portion 8 formed behind the cover 2, and can be slid rearward while maintaining a horizontal posture. Become.

  When the cover 2 is in the open position, the boss 13 protruding from the inner side surface of the side cover 2b is positioned in front of the band-shaped moderation piece 12 that is cantilevered on the outside of the side frame 32A. When sliding backward in the posture, the boss 13 gets over the outer surface of the band-shaped moderation piece 12. As a result, a moderation similar to a click feeling was obtained while the cover 2 was slid from the open position to the lock position, and the operator switched the position between the open position and the lock position by sliding the cover 2. Can know. In particular, in the present invention, since the cover 2 rotates at both the open position and the lock position, it is possible to perform a slide operation from the open position to the lock position while the cover 2 is open (hereinafter, this operation is referred to as an erroneous operation). ) When the cover 2 is in a horizontal position, the upper surface 6a of the cover lock portion 6 is slid from the open position to the lock position along the lower surface 8a of the case lock portion 8 (hereinafter, this operation is referred to as normal operation). 13 generates a moderation over the belt-shaped moderation piece 12, and can notify the operator that a normal operation distinguished from an erroneous operation has been performed.

  When the cover 2 is slid rearward to a position where the pivot 5 becomes the lock position of the rear end of the bearing hole 4 under normal operation, the distal end of the positioning piece 11 comes into contact with the pivot 5 from the front. Positioned at the lock position. Accordingly, the cover 2 is positioned at the lock position shown in FIGS. 3A and 3B unless an external force of a certain level or more is applied so that the pivot 5 gets over the positioning piece 11.

  In the locked position, as shown in FIG. 6, the upper surface 6 a of the cover lock portion 6 abuts on the lower surface 8 a of the case lock portion 8, and the rotation of the cover 2 in the opening direction is restricted and received in the card storage portion 10. The upper surface of the memory card 110 is pressed by the cover body 2a, and the contact 9 comes into elastic contact with the conductive pad.

  As described above, the memory card connector 1 according to the present embodiment can slide the cover 2 from the open position to the lock position even if it is erroneously operated. As shown in FIG. 10, the cover lock portion 6 and the case lock portion 8 are in an unlocked state where they are not engaged. In this erroneous operation, the boss 13 does not have a moderation over the belt-shaped moderation piece 12, so that an operator who has noticed an erroneous operation can slide the cover 2 forward and close the cover 2 at the lock position to perform a normal operation. However, in the present embodiment, the cover 2 that has been slid to the lock position by an erroneous operation can be forcibly closed, and the cover lock portion 6 can be engaged with the case lock portion 8 to be locked.

  That is, when the erroneously operated cover 2 is closed at the lock position, as shown in FIG. 11, the crank-like downward slope of the cover lock portion 6 is formed on the upper surface 8b that curves outwardly of the case lock portion 8 that is folded back downward. The surfaces abut. Further, when an operating force in the closing direction is applied to the cover 2, the cover lock portion 6 is guided downward along the inclined upper surface 8 b of the case lock portion 8 while the metal cover lock portion 6 and the case lock portion 8 are bent. Then, when over the case lock portion 8, the upper surface 6a of the cover lock portion 6 and the lower surface 8a of the case lock portion 8 face each other and engage with each other as shown in FIG. As a result, the cover 2 is locked to the case body 3 at the lock position as in the normal operation.

  When the memory card 110 is removed from the memory card connector 1, the cover 2 at the lock position shown in FIGS. 3 (a) and 3 (b) is slid forward with an operating force such that the pivot 5 gets over the positioning piece 11. . Similarly to the reverse direction, the cover 2 that slides from the lock position to the open position is guided in the lower surface 8a of the case lock portion 8 formed behind the cover lock portion 6 while maintaining a horizontal posture. During the sliding, a moderation occurs in which the boss 13 rides over the band-shaped moderation piece 12.

  When the cover 2 reaches the open position, the cover lock portion 6 is released from the case lock portion 8 and can be rotated. Therefore, the cover 2 is opened as shown in FIGS. 1A and 1B, and the memory card 110 is removed.

  In the above-described embodiment, the bearing hole 4 and the case lock portion 8 are formed in the side frame 32A made of the metal frame 32. However, the side frame is not necessarily made of metal, and is made of the same synthetic resin as the insulating base 31. It can also be formed.

  Moreover, although the side cover 2b of the cover 2 was demonstrated in the example which slides along the outer side of the side frame 32A, it may slide along an inner side. In this case, of course, the case lock portion 8 is formed inside the side frame 32A, and the cover lock portion 6 is formed outside the side cover 2b.

  Further, the memory card may be temporarily held on the cover 2 side until the cover 2 moves to the lock position, like the conventional memory card connector 100.

  Further, the side frame 32A of the portion where the bearing hole 4 is formed is folded in a downward U-shape with the upper part of the belt-like side plate portion inwardly, but the direction is arbitrary, and the downward direction is downwardly U-shaped. It may be folded.

  Suitable for memory card connectors that connect memory cards to electronic devices such as mobile phones.
