Description

  The present disclosure relates to a card connector.

  2. Description of the Related Art Conventionally, electronic devices such as mobile phones have a card connector in order to use various cards such as a SIM card. In recent years, with the rapid miniaturization of electronic devices, cards and card connectors tend to be rapidly miniaturized. Therefore, it is difficult for the user to grasp the card with his / her fingers or to properly insert the card into the card connector. Therefore, a card connector in which a card is set in a card tray in advance and the card tray is inserted has been proposed (for example, see Patent Document 1).

  FIG. 10 is a view showing a conventional card connector.

  In the figure, reference numeral 811 denotes a housing of a card connector made of an insulating resin material. Reference numeral 861 denotes a shell made of a metal plate, which is attached to the housing 811 so as to cover the housing 811 from above. Reference numeral 961 denotes a card tray in which a card 901 is loaded. The card tray 961 is inserted into the space formed between the housing 811 and the shell 861 from the insertion opening 818 and accommodated in a state in which the card 901 is loaded inside. The card 901 includes an electrode pad (not shown) on the lower surface, and the electrode pad is exposed on the lower surface of the card tray 961.

  The shell 861 has a cantilever lock 875 formed therein, and the card tray 961 is accommodated in the space for the card connector, and a cutout formed in the card tray 961. 968. This prevents the card tray 961 from coming off the space of the card connector.

  Further, the housing 811 includes a push rod and an eject lever (not shown). Then, when removing the card tray 961 from the space of the card connector, the user inserts an auxiliary member such as a pin or a rod into a through hole 963a formed in a flange portion 963 of the card tray 961. Slide the push rod toward the back with the tip of the auxiliary member. Then, the eject lever operates to displace the card tray 961 from the back toward the front. As a result, the engagement between the shell 861, the lock portion 875, and the cutout portion 968 of the card tray 961 is released, and the card tray 961 is ejected from the insertion slot 818 to the front.

Japanese Utility Model Registration No. 3186801

  However, in the conventional card connector, when the card tray 961 is ejected, the engagement between the lock portion 875 and the notch portion 968 is released against the spring force of the lock portion 875, so that the card tray 961 is disengaged. It is necessary to apply a certain amount of force to the push rod for operating the eject lever for displacing the 961 toward the front and slide the push rod. Therefore, the user has to exert a relatively large force to slide the push rod despite using the fine auxiliary member, and it is difficult to discharge the card tray 961. I feel it.

  Also, when inserting the card tray 961, a certain amount of force is applied to the card tray 961 so that the lock portion 875 and the notch portion 968 are engaged with each other against the spring force of the lock portion 875. It is necessary to be displaced toward, which makes the operation difficult.

  However, if the spring force of the lock portion 875 is reduced to facilitate the operation of ejecting and inserting the card tray 961, only a small external force such as a small shock is applied to the card connector during use of the card. However, the engagement between the lock portion 875 and the notch portion 968 is released, and the card tray 961 is unnecessarily discharged.

  Here, the card module is securely held such that the lock of the card module by the rotatable locking member is released when the card module is ejected by solving the conventional problem. It is another object of the present invention to provide a highly reliable card connector capable of easily inserting and ejecting a card module.

Therefore, in the card connector, a card connector into which a card module can be inserted, a discharging mechanism for discharging the card module from the card connector, and a locking mechanism capable of locking a locked portion of the card module. A locking member for rotating the fulcrum about a fulcrum between a locking position for locking the locked portion and a release position for unlocking the locked portion. Ri rotatably der, the discharge mechanism includes an insert and a slidable eject operation member in the discharging direction of the card module, the fulcrum portion is pivotally attached to rotation receiver said eject operation member comprises The locking member includes a pressure receiving member, and when the pressure receiving member is pressed by an operation assisting member that operates the discharge mechanism, the locking member pivots from a locking position to a release position, and the discharging operation member You slide.

  In still another card connector, the locking member is further urged toward the locking position by an urging member.

  In still another card connector, the ejection operation member is a member made of a metal plate, and the urging member is a leaf spring formed integrally with the ejection operation member.

  In still another card connector, the locked portion further includes a locked edge extending in a direction intersecting the card module insertion and ejection direction, and the locking member is positioned at a locking position. , The distal end of the locking member faces the locked edge.

  In still another card connector, the locked edge portion extends in a direction inclined with respect to the insertion and ejection directions of the card module, and the arc-shaped trajectory of the tip of the locking member is Intersects with the locked edge.

  In still another card connector, the angle at which the locked edge inclines with respect to the insertion and ejection directions of the card module is different from the insertion and ejection directions of the trajectory at the release position with respect to the insertion and ejection directions of the card module. Smaller than the angle.

  In still another card connector, the ejection operation member is urged by a return spring in the ejection direction of the card module.

  The card connector is configured so that the card module is unlocked by the rotatable locking member when the card module is ejected, so that the card module is securely held and the card module is removed. A highly reliable card connector that can be easily inserted and ejected can be obtained.

Further, the card tray 160 may have a shape and dimensions suitable for being inserted into the card connector 1 and house a memory card therein. In short, the card module 102 may be any type of module as long as it can be inserted into the card connector 1 and can conduct with the electronic device through the card connector 1.

  In the present embodiment, for convenience of explanation, a case where the card module 102 is a card tray 160 as a card holding member accommodating a card (not shown) will be described. Further, the card will be described as a 4FF card, a so-called nano SIM card. According to the card standard ETSI TS 102 221 V11.00, the size of the nano SIM card is 12.3 mm in front and rear length, 8.8 mm in width, and 0.67 mm in thickness. It is prescribed.

  Note that, in the present embodiment, directions such as upper, lower, left, right, front, and rear are used to describe the configuration and operation of each part of the card connector 1, the card module 102, and the card tray 160. The representations shown are relative rather than absolute and are appropriate when the card connector 1, card module 102 and card tray 160 or their components are in the orientation shown in the figures. When the attitude of the connector 1, the card module 102, the card tray 160, or the components thereof changes, it should be interpreted as being changed according to the change in the attitude.

  The card tray 160 includes a frame portion 161 having a shape facing the side surface of the card and surrounding the side surface, and a flange plate 163 serving as a rear end plate connected to a rear end of the frame portion 161. In. The flange plate 163 is a linear rod-shaped member through which an operation assisting member 181 for operating a discharge mechanism for discharging the card tray 160 is inserted, and penetrates the flange plate 163 in the thickness direction. An operation insertion hole 163a is formed. As shown in FIG. 2, the card tray 160 is inserted into the card tray 160 such that the front end 161 f of the frame 161 faces the inner part of the card tray 160. The frame 161 and the flange plate 163 may be made of any material. For example, at least a part of the periphery of the metal member is made of resin by a molding method called insert molding or overmolding. It is a member covered with and integrated with.

  The frame part 161 is a substantially rectangular frame member surrounding four sides of a space part 166 as a card accommodating space for accommodating cards, and includes a plurality of parallel horizontal frame parts 165 extending in the width direction. And a pair of left and right side frame portions 164 connecting the left and right ends of the horizontal frame portion 165. The horizontal frame portion 165 includes a front frame portion 165a positioned at the front end, a rear frame portion 165c positioned at the rear end, and a middle frame portion 165b positioned between the front frame portion 165a and the rear frame portion 165c. Contains. A locked portion 167 is formed on one side frame portion 164 (in the example shown in the drawing, on the right side in the insertion direction of the card tray 160). The locked portion 167 is, in the example shown in the drawing, a locking projection 167c protruding outward in the width direction, and a portion of the locking projection 167c formed on the rear side in the insertion direction of the card tray 160. There is an inclined edge 167a as a locked edge extending in a direction intersecting with the insertion and ejection direction of the card tray 160, and a concave inward in the width direction formed on the rear side of the inclined edge 167a. Locking recess 167b. Preferably, the inclined edge 167a extends in a direction inclined with respect to the insertion and ejection directions of the card tray 160. Further, the locking projection 167c may be omitted.

  The space 166 of the card tray 160 in the present embodiment is divided into a first space 166a located on the front side and a second space 166b located on the rear side. The card can be accommodated in each of the first space 166a and the second space 166b, and the lower surfaces of the first space 166a and the second space 166b are openings through which the electrode pads of the card can be exposed. . The first space 166a and the second space 166b can accommodate cards one by one. Further, the card may be accommodated only in one of the first space 166a and the second space 166b, and the other may not be accommodated. Furthermore, for example, when a card connector other than the card connector 1 is mounted on the electronic device, the user may not use the card connector 1. Then, in such a case, the user can keep the card tray 160 that does not contain a card, that is, the empty card tray 160 inserted into the card connector 1.

  As shown in FIG. 1, the card connector 1 is fixed to an external member 95 provided in an electronic device (not shown). The external member 95 is a part of the housing of the electronic device to which the card connector 1 is attached, is a separate member independent of the card connector 1, and the card connector 1 may be directly fixed. Alternatively, it may be fixed via a position fixing member (not shown) so that the relative positional relationship with the card connector 1 does not change. The position fixing member is, for example, a wiring board on which the card connector 1 is mounted, a housing of an electronic device to which the card connector 1 is mounted, and the like. Here, the description will be made assuming that the external member 95 is a part of the housing of the electronic device. The outer surface of the external member 95 functions as an outer surface of a housing of the electronic device. In FIG. 2, the illustration of the external member 95 is omitted.

  The external member 95 has an insertion opening 95a formed to penetrate in the thickness direction. The insertion opening 95a has a shape and a size that allow the card tray 160 to be inserted, and the flange plate 163 of the card tray 160 can be fitted therein. The outer shape and outer dimensions of the flange plate 163 are the same as those of the insertion opening 95a. As shown in FIG. 1, the flange plate 163 can be fitted into the insertion opening 95a. Then, as shown in FIG. 1, when the insertion of the card tray 160 into the card connector 1 is completed, the rear surface of the flange plate 163 is substantially flush with the outer surface of the external member 95.

  In the present embodiment, the card connector 1 is formed by punching and bending a housing 11 integrally formed of an insulating material such as a synthetic resin and a plate made of a conductive metal. And a shell 61 as a cover member to be described later, which is integrally formed and attached to the upper side of the housing 11. The shell 61 covers at least a part of the card tray 160 inserted into the housing 11 and the card connector 1. The card connector 1 has a substantially flat rectangular parallelepiped shape, is attached to the electronic device, and the card tray 160 is inserted into the housing 11 from the rear (lower right in FIG. 1) insertion port. Specifically, the card tray 160 is inserted into a card storage space formed between the housing 11 and the shell 61.

  The housing 11 extends in the width direction along a front end portion of the housing 11 in the insertion direction of the card tray 160 in the housing 11 and a bottom wall portion 11b as a substantially rectangular flat terminal holding portion. A thicker inner wall portion 11a and a pair of side wall portions 11d extending in the insertion direction along the left and right side edges of the housing 11 and having a greater wall thickness than the bottom wall portion 11b (in the example shown in FIG. It extends in the insertion direction on the outer side in the width direction of the side wall 11d (on the right side in the insertion direction of the card tray 160), and includes an outer wall 11e thicker than the bottom wall 11b. The lower surface of the inner wall 11a, the side wall 11d, and the outer wall 11e is flush with the lower surface of the bottom wall 11b, and the upper surface is located above the upper surface of the bottom wall 11b. The rear end of the housing 11 in the insertion direction of the card tray 160 is referred to as a rear end 11r.

  Further, the bottom wall portion 11b includes a plurality of terminals as connection terminals, but the illustration of the terminals is omitted in the drawings for convenience of explanation. The terminals are arranged so as to contact each of the electrode pads of the card in the card tray 160 held in the card connector 1. Therefore, the number and arrangement of the terminals are appropriately changed so as to conform to the number and arrangement of the electrode pads of the card.

  A slide groove 12 is formed between the outer wall 11e and one side wall 11d, and a card tray 160 as the card module 102 inserted into the card connector 1 is discharged into the slide groove 12. A push rod 22 as a discharge operation member in the discharge mechanism for performing the operation is slidably mounted in the front-rear direction (in the direction of insertion and discharge of the card tray 160).

  The push rod 22 is a substantially linear rod-shaped or band-shaped member, and a guide concave portion 22c that engages with a guide convex portion 12a protruding from the side surface is formed on a side surface facing the outer wall portion 11e. I have. At the front end of the push rod 22, an engaging portion 22b is formed which engages with a power point portion 21b of the eject lever 21. The eject lever 21 is a lever-shaped member disposed near the back wall 11a and functions as a discharge lever member in a discharge mechanism. For this reason, the eject lever 21 is pivotally attached to a support shaft 11c formed on the bottom wall 11b at the fulcrum 21c. The end of the eject lever 21 opposite to the fulcrum 21b across the fulcrum 21c abuts on the tip 161f of the frame 161 of the card tray 160 inserted into the card connector 1, The card tray 160 functions as an action point 21a for applying a force in the ejection direction to the card tray 160.

  A rotation lock member 25 as a locking member is rotatably attached to the rear end of the push rod 22. The rotation lock member 25 is centered on the fulcrum 25c between a locking position for locking the locked portion 167 of the card tray 160 and a release position for releasing the locking of the locked portion 167. And can be rotated. In the example shown in the figure, the rotation lock member 25 is a substantially triangular plate-shaped member whose width decreases from the base end toward the distal end portion 25a in a plan view. A portion 25c is formed. The fulcrum 25c is rotatably attached to a rotation receiving portion 22e formed at the rear end of the push rod 22. In the present embodiment, the fulcrum 25c is a through hole that penetrates the rotation lock member 25 in the thickness direction, and the rotation receiving portion 22e is a shaft that protrudes from the push rod 22, and the fulcrum is Reference numeral 25c is rotatably fitted to the rotation receiving portion 22e.

  Further, at the base end of the rotation lock member 25, a pressure receiving member 25b is formed as a force point portion which is pushed in the insertion direction of the card tray 160 by the distal end 181a of the operation assisting member 181. In the example shown in the figure, the pressure receiving member 25 b is a plate-shaped member extending in a direction substantially perpendicular to the insertion and ejection directions of the card tray 160, and is integrated with the rotation lock member 25. Is formed. In a plan view, the position where the tip 181a of the operation assisting member 181 in the pressure receiving member 25b abuts, that is, the point of force is defined by a straight line that passes through the center of the fulcrum 25c and extends in the insertion direction of the card tray 160. Are also located inside the housing 11 in the width direction. Therefore, when the pressure receiving member 25b is pushed in the insertion direction of the card tray 160 by the tip 181a of the operation assisting member 181, the rotation lock member 25 rotates clockwise around the fulcrum 25c in plan view. The distal end portion 25a is displaced outward in the width direction of the housing 11.

  Further, the rotation lock member 25 is rotated counterclockwise about the fulcrum 25c in plan view by the urging member 24, and the distal end 25a is displaced inward in the width direction of the housing 11. And so on. In the example shown in the figure, the biasing member 24 is a leaf spring bent in a substantially rectangular shape, and has a main body 24a extending in the insertion direction of the card tray 160, and a main body 24a. And a cantilever-shaped operating portion 24b that is bent and extends in a direction inclined with respect to the insertion direction of the card tray 160. The main body portion 24a is fixed to the push rod 22, and the tip of the operating portion 24b presses the side surface of the rotation lock member 25 on the outer side in the width direction of the housing 11, whereby the rotation lock member 25 is urged. Therefore, the distal end portion 25a of the rotation lock member 25 enters the locking concave portion 167b of the card tray 160 inserted into the card connector 1, faces the inclined edge portion 167a, and moves the locked portion 167. It becomes possible to lock.

  The rotation range of the rotation lock member 25 is defined by the inner limiter 22a and the outer limiter 22d that can abut the widthwise inner side surface and the outer side surface of the housing 11 of the rotation lock member 25, respectively. The inner limiter 22a and the outer limiter 22d are formed on the push rod 22. Therefore, when the pressure receiving member 25b is pushed by the operation assisting member 181, the rotation lock member 25 rotates from the locked position to the release position, and the push rod 22 slides. When the insertion of the card tray 160 into the card connector 1 is completed and the frame portion 161 is at a predetermined position in the card connector 1 as shown in FIG. 1, the inner limiter 22a rotates. It does not come into contact with the lock member 25.

  Next, the operation of the card connector 1 having the above configuration will be described. First, the operation for discharging the card tray 160 will be described.

  FIG. 3 is a plan view showing the operation of ejecting the card tray from the card connector according to the first embodiment. FIG. 4 is the rotation in ejecting the card tray from the card connector according to the first embodiment. FIG. 5 is a first diagram illustrating the operation of the lock member, and FIG. 5 is a second diagram illustrating the operation of the rotation lock member when the card tray is ejected from the card connector according to the first embodiment. 3 (a) to 3 (d) are views showing each stage, and in FIGS. 4 and 5, (a) is a plan view and (b) is an enlarged view of a portion A in (a).

  Here, it is assumed that the card tray 160 has been inserted into the card connector 1 and the frame portion 161 is at a predetermined position in the card connector 1 as shown in FIG. For convenience of illustration, it is assumed that the shell 61 has been removed and no cards are stored in the card tray 160.

  As shown in FIG. 3A, when the insertion of the card tray 160 into the card connector 1 is completed, the rotation lock member 25 is moved inward in the width direction of the housing 11 by the urging member 24. The rotation lock member 25 is in the locked position, and the tip end 25a of the rotation lock member 25 enters the locking recess 167b of the card tray 160 inserted into the card connector 1, and the inclined edge portion The locked portion 167 is locked opposite to the locked portion 167a. Therefore, for example, even when an external force such as an impact received when the electronic device on which the card connector 1 is mounted falls on the floor is applied to the card connector 1, the locked portion by the rotation lock member 25 is applied. Since the lock of the card tray 167 is not released, the card tray 160 is securely held in a state of being accommodated in the card connector 1, and does not detach from the card connector 1.

  In this state, it is desirable that the tip portion 25a and the inclined edge portion 167a are in contact with each other as shown in FIG. Thereby, the card tray 160 is stably held in the card connector 1. As shown in FIGS. 1 and 4A, if the flange plate 163 is fitted into the insertion opening 95a of the external member 95 and cannot be displaced forward in the insertion direction of the card tray 160, the card tray 160 is The rattling in the insertion direction is prevented. If the side frame portion 164 of the card tray 160 opposite to the locking projection 167c is in contact with the side wall portion 11d of the card connector 1 opposite to the slide groove portion 12, the card tray 160 will not be moved. Rattling in the width direction of the connector 1 is also prevented.

  Further, in plan view, the trajectory of the distal end portion 25a of the rotation lock member 25 is an arc centered on the fulcrum portion 25c as shown by a dotted line C in FIG. It is desirable that the point abutting on the portion 167a intersects a dotted line F which is a straight line representing the surface of the inclined edge 167a. In this case, if a straight line extending in the insertion direction of the card tray 160 is located outside of the card connector 1 in the width direction from a position where the leading end portion 25a and the inclined edge portion 167a are in contact with each other, an arc is shown. The angle α2 at which the dotted line C intersects the straight line D is greater than the angle α1 at which the dotted line F representing the surface of the inclined edge 167a intersects the straight line D (α2 <90 degrees and α1 <90 degrees). That is, the angle α1 at which the inclined edge 167a is inclined with respect to the insertion and ejection direction of the card tray 160 is smaller than the angle α2 of the trajectory of the leading end 25a at the release position with respect to the insertion and ejection direction of the card tray 160. Further, it is preferable that, of the two intersections of the dotted line C and the dotted line F indicating the arc, the intersection closer to the release position is on the surface of the inclined edge 167a. Therefore, as shown in FIG. 5B, the distal end 25a is separated from the inclined edge 167a in a range outside the card connector 1 in the width direction from the position where the distal end 25a and the inclined edge 167a contact. The tip 25a approaches the inclined edge 167a as it approaches the position where the tip 25a and the inclined edge 167a come into contact with each other.

  Then, when ejecting the card tray 160 from the card connector 1, the user grips the operation assisting member 181 with his / her finger or the like, and adjusts the posture and position of the operation assisting member 181 by the tip 181 a of the operation assisting member 181. It faces forward and is located immediately behind the operation insertion hole 163a of the flange plate 163.

  Subsequently, the user advances the operation assisting member 181 to insert the distal end 181a into the rotation lock attached to the rear end of the push rod 22 through the operation insertion hole 163a as shown in FIG. The member 25 is brought into contact with the pressure receiving member 25b. When the user pushes the operation assisting member 181, the pressure receiving member 25 b is pushed in the insertion direction of the card tray 160, and the rotation lock member 25 is fulcrumd against the urging force of the urging member 24. It rotates clockwise around the portion 25c. Then, as shown in FIG. 3B, the distal end portion 25a of the rotation lock member 25 is displaced outward in the width direction of the housing 11, and the rotation lock member 25 is located at the release position and locked. The locking of the protrusion 167c is released.

  As described above, assuming that the trajectory of the distal end portion 25a is an arc as shown by a dotted line C in FIG. 4B, the card connector 1 is located at a position higher than the position at which the distal end portion 25a and the inclined edge 167a abut. In the range outside in the width direction, the distal end portion 25a is separated from the inclined edge portion 167a, so that the rotation lock member 25 can smoothly rotate clockwise, and the locked portion 167 is locked. , Will be released smoothly.

  Subsequently, when the user further advances the operation assisting member 181, the rotation locking member 25 is in a non-rotatable state since the outer side in the width direction of the housing 11 abuts against the outer limiter 22 d and the housing 11 cannot rotate. As shown in (c), the push rod 22 is advanced. Then, the force point portion 21b of the eject lever 21 which engages with the engaging portion 22b of the push rod 22 is displaced forward, so that the front frame portion 165a is pushed by the action point portion 21a of the eject lever 21 and the card tray is pushed. 160 is displaced rearward from a predetermined position.

  As a result, the flange plate 163 of the card tray 160 projects sufficiently rearward from the insertion opening 95a of the external member 95. Therefore, the user can pull out and eject the card tray 160 from the card connector 1 by gripping the flange plate 163 with fingers or the like. When the user retracts the operation assisting member 181, the rotation lock member 25 rotates counterclockwise by the urging force of the urging member 24, and as shown in FIG. Contacts the side surface of the side frame portion 164 of the card tray 160. However, in the range of the side frame portion 164 in front of the locked portion 167, no irregularities are formed, so that the front end portion 25a does not catch on the side frame portion 164, and the card tray 160 It can be displaced smoothly backward.
