  With IC cards, as seen in, for example, SIM cards and MicroSD cards, the miniaturization and thinning of the ICs are increasingly progressing. Accordingly, for example, there is a strong demand for miniaturization and thinning (hereinafter also referred to as low profile) of a card connector attached to a portable device, for example.

  By the way, for example, in a card connector provided with a push-type eject mechanism, a slide member for transporting an IC card and a lock mechanism for locking and holding the slide member when the card is mounted in the card storage space are required. Furthermore, when the lock is released when the card is ejected from the card storage space, a spring member is required to bias the slide member in the ejection direction. However, in a connector having a conventional eject mechanism, the connector structure is complicated and the number of parts is increased. For this reason, there is a limit to the miniaturization and thinning of the card connector provided with the eject mechanism. Further, it is difficult to reduce the cost of a card connector having a conventional eject mechanism.

  The present invention has been made in view of the above-described circumstances, and simplifies the structure of an ejection mechanism used for inserting / removing an IC card into / from a card accommodation space, and reduces the number of components. And it aims at making the cost reduction easy while removing the limit of size reduction and thickness reduction of a card connector provided with it.

In order to achieve the above object, a card connector according to the present invention includes a card housing space provided with a card insertion / extraction slot by a base member having a plurality of contacts and a cover member made of a leaf spring material superimposed on the base member. The card connector is provided with an eject mechanism that is used to insert and remove a card from the card accommodation space, and the eject mechanism is configured such that a part of the upper wall of the cover member faces downward toward the card accommodation space. A lock spring piece formed by cutting and raising , and made of a thin metal material, and when the card is held in the card receiving space, it is formed in a pair of facing groove walls and the tip of the lock spring piece is engaged Sula is an engaging portion is, and a receiving groove formed between the pair of groove walls mutually the opposite, reciprocates insertion direction of the card And de member, a spring member for urging the slide member in the ejection direction of the card, made of a sheet metal material, is movably disposed within the receiving groove of the sliding member, the distal end of the locking spring piece And a lock release member having a protrusion portion that is spaced apart from the engagement portion of the slide member, and the protrusion portion of the lock release member separates the tip of the locking spring piece from the engagement portion of the slide member. The sliding member and the locking spring piece are movably arranged .

  According to the present invention, in a card connector provided with an ejection mechanism, the ejection mechanism has a very simple structure. For example, the number of parts of the push type eject mechanism is reduced, and further miniaturization and thinning of the card connector are promoted. Further, the cost of the card connector having the eject mechanism can be easily reduced.

Alternatively, the presser piece 22 is provided. Here, the bent piece 21 is formed by punching a part of the cover member 12 and bending it.

A guide groove 23 is provided on the bottom wall 11 a of the base member 11. The slide member 17 slides in the guide groove 23 and linearly reciprocates in the card insertion / removal direction. Incidentally, the lock release lever 18 is then sliding fit in the slide member 17, the reciprocating motion of the slide member 17, it is hardly moved backward in the direction of card ejection. A guide groove 23 is provided on the bottom wall 11 a of the base member 11. The slide member 17 slides in the guide groove 23 and linearly reciprocates in the card insertion / removal direction. Note that the lock release lever 18 slides on the slide member 11 and hardly moves backward in the card ejection direction in the reciprocating motion of the slide member 17.

  As shown in FIG. 2A, the slide member 17 is provided with a receiving groove storage portion 17a having a U-shaped cross section in a direction orthogonal to the card insertion / removal direction. The lock release lever 18 is assembled and stored in the storage portion 17a. And the card | curd contact part 17b which the front-end part curves and contacts the front end of a card | curd is formed. The card abutting portion 17b abuts on the front end of the card to be mounted so that the card can be inserted and removed smoothly. Accordingly, the card abutting portion 17 b is provided at the front end of the slide member 17 so as to be substantially perpendicular to the card insertion / removal direction and extend into the card accommodation space 13.

  Further, the slide member 17 engages with the locking spring piece 20 described above at a predetermined position of the two groove walls 17c, 17c defining the storage portion 17a of the slide member 17 as will be described in detail later. An engaging portion 17d that is locked and held is provided.

  In addition, a recessed portion 17e that is recessed downward is provided in the inner bottom portion of the storage portion 17a, and slides into the guide groove 23 provided in the bottom wall 11a of the base member 11 so that the slide member 17 is straight in the card insertion / removal direction. The reciprocating motion can be easily performed. Further, a spring receiving portion 17 f is provided on the rear end side of the slide member 17. The spring receiving portion 17 f is extrapolated to the coil spring 19.

  The coil spring 19 elastically expands and contracts between a spring receiving protrusion 24 fixed to the front wall 11 b of the base member 11 and a spring receiving portion 17 f of the slide member 17. The slide member 17 is constantly urged in the card ejection direction.

  As shown in FIG. 2B, the lock release lever 18 is formed with a protrusion 18a at the top of the front end region. The protrusion 18a has, for example, a first inclined surface 181a that is inclined from the tip of the lock release lever 18 to the card ejection direction. And the 2nd inclined surface 182a which inclines in the card | curd discharge direction from the vertex of the protrusion part 18a is formed.

  A push portion 18 b is provided at the rear end of the lock release lever 18. By the push operation of the push portion 18b, the protrusion 18a elastically deforms the locking spring piece 20 upward. Then, the loaded card is ejected from the card accommodation space 13 by the slide member 17 unlocked. Here, even if the lock release lever 18 becomes smaller with the miniaturization of the card connector 10, the push portion 18b is preferably formed in a structure having a certain size so that the push operability by a person does not deteriorate. .

  And the latching | locking part 18c is provided in the intermediate | middle area | region of the lock release lever 18, for example. The locking portion 18 c engages with the bent piece 21 provided integrally with the upper wall 12 a of the cover member 12. By this engagement, the backward movement of the lock release lever 18 in the card ejection direction is prevented and fixed.

  The lock release lever 18 is provided with a pressed portion 18d. The pressed portion 18d is pressed and brought into sliding contact with a pressing piece 22 provided integrally with the upper wall 12a of the cover member 12. Here, the pressed portion 18d is convex upward, for example. Further, a stopper portion 18e may be provided so as to be joined to the push portion 18b of the lock release lever 18. The stopper portion 18e can function to stop the elastic extension of the coil spring 19 during card ejection.

  Both the slide member 17 and the lock release lever 18 are made of a metal material. As the metal material, for example, stainless steel, aluminum, an alloy, or the like, which has mechanical strength and is easy to process is suitable. In addition, it is preferable that the push part 18b of the lock release lever 18 is formed with insulators, such as insulating resin. Thus, electrical damage such as destruction of the card IC due to static electricity from the human body can be easily prevented.

  The above-described slide member 17 is manufactured in accordance with the longitudinal length of the card connector 10 whose width dimension is about 10 mm to 12 mm and whose longitudinal dimension is about 12 mm to 14 mm, for example. The IC card mounted on such a connector has a width dimension and a length dimension of about 7 mm to 9 mm and about 11 mm to 13 mm, respectively, and a thickness of about 0.5 mm to 0.8 mm. Therefore, for example, a thin metal plate such as stainless steel having a thickness of about 0.4 mm is punched and subjected to bending, embossing, finishing, or the like. And the length dimension of the card insertion direction of the slide member 17 is set suitably according to the length dimension of a card | curd as mentioned above.

  In the production of the lock release lever 18 as well, a metal plate such as stainless steel having a thickness of about 0.4 mm is punched out and processed by bending, plastic working, finishing, or the like. The length of the lock release lever 18 in the rod shape and the card insertion / removal direction is set according to the size of the slide member 17. Further, the width dimension of the lock release lever 18 is manufactured to be about 0.5 mm to 1 mm, for example.

  The slide member 17 and the lock release lever 18 may have various other shapes or structures. For example, the slide member 17 has a semi-cylindrical structure in the middle region, and the rod-like lock release lever 18. May be shaped so as to be inserted into the half cylinder. The lock release lever 18 can have a required shape such as a columnar shape, an elliptical column shape, or a prism shape.

  Note that the slide member 17 and the lock release lever 18 can be made of a strong non-metallic material such as a carbon material instead of the metallic material. As described above, the slide member 17 and the lock release lever 18 are miniaturized in accordance with the card connector that is reduced in size and height, so that such a non-metallic material is excellent in mechanical strength and processability. Are preferred.

  The card connector 10 is attached with a card detection mechanism. The card detection mechanism is basically a switch, and has a switch spring piece 25 having elasticity and conductivity, and a switch facing piece 26 facing the switch spring piece 25 as a pair of switch pieces.

  Next, attachment of the ejection mechanism 16 to the card connector 10 will be described with reference to FIG. First, a contact 15 is attached to the bottom wall 11a of the base member 11, and a switch spring piece 25 and a switch facing piece 26 of the card detection mechanism are attached to the front end thereof. Then, the coil spring 19 is inserted into the spring receiving protrusion 24 along the right side wall 11 c of the base member 11. Thereafter, the slide member 17, the rod release lever 18, and finally the cover member 12 are overlapped with the base member 11 serving as the connector body in a region along the right side wall 11 c of the base member 11, and the card connector 10 is assembled.

  The slide member 17 is attached so that the recessed portion 17e fits into a guide groove 23 provided in the bottom wall 11a in a region along the right side wall 11c of the base member 11. Here, the guide groove 23 is formed in a required length along the card insertion / removal direction. At the time of attachment, the coil spring 19 is slightly compressed, and the spring receiving portion 17 f of the slide member 17 is extrapolated to the rear end side of the coil spring 19.

  Next, the lock release lever 18 is assembled so as to be fitted into the storage portion 17 a of the slide member 17. At the time of attachment, the push portion 18b of the lock release lever 18 is arranged so that the lower end thereof is combined with the rear wall 11e of the base member 11 shown in FIG.

  The cover member 12 is combined with the base member 11. The cover member 12 is overlapped with the base member 11 such that the right side wall 12c and the left side wall 12d thereof cover the outside of the right side wall 11c and the left side wall 11d of the base member 11, respectively. At that time, the protrusion 18 a of the lock release lever 18 protrudes upward through the opening 20 a of the lock spring piece 20 provided on the upper wall 12 a of the cover member 12. Further, the locking portion 18 c is disposed so as to engage with the front end of the bent piece 21 provided on the upper wall 12 a of the cover member 12. Further, the pressed portion 18d is pressed by a pressing piece 22 provided on the upper wall 12a of the cover member 12.

  In the card connector 10 assembled in this way, the lock release lever 18 will be described in detail later. When the push portion 18b comes into contact with the notch portion 12e provided in the cover member 12 shown in FIG. Forward movement in the direction is restricted. The lock release lever 18 slides on the slide member 11 and does not follow the reciprocating motion in the card insertion / removal direction along the guide groove 23 of the slide member 17. Even if the follow-up occurs, the forward movement and the backward movement of the lock release lever 18 are guaranteed to be within an allowable range by the notch 12e and the bent piece 21 described above.

  Next, the operation of the card connector 10 of this embodiment will be described with reference to FIGS. As shown in FIG. 4, for example, the IC card 100, which is smaller than a MicroSD card, is inserted into the card connector 10 from the card insertion / extraction opening 14 by pressing the rear end portion 100a. Prior to card insertion, the slide member 17 and the lock release lever 18 of the eject mechanism 16 are in their initial positions. Then, the rear end portion 100a is pressed in a state where the front end portion 100b of the IC card 100 is in contact with the card contact portion 17b of the slide member 17. By this pressing, the slide member 17 is inserted along the guide groove 23 against the urging force of the coil spring 19.

  Then, the slide member 17 is pushed to such an extent that the front end of the card abutting portion 17b is in contact with the front wall 11b of the base member 11, for example. At the same time, the switch spring piece 25 of the card detection mechanism is elastically displaced forward by the front end portion 100b of the IC card 100. In this way, the switch spring piece 25 and the switch facing piece 26 are contacted and separated, and insertion of the IC card 100 into the card accommodation space 13 is detected. When the IC card 100 is pushed, the lock release lever 18 hardly moves from the initial position.

  Thereafter, when the push of the IC card 100 is stopped, the slide member 17 is slightly retracted in the card ejection direction by the urging of the coil spring 19 to be locked. As shown in FIG. 5, the engaging portion 17 d at the front end of the slide member 17 is locked by the locking spring piece 20, and the slide member 17 is held and locked against the elastic bias of the coil spring 19. In this locked state, a contact pad (not shown) provided on the lower surface of the IC card 100 is in pressure contact with the contact 15. Further, as described above, the card detection mechanism detects card insertion. In this way, the IC card 100 inserted together with the slide member 17 is accommodated in the card accommodating space 13, and the mounting thereof is completed.

  When the IC card 100 is detached from the card connector 10, the rear end of the push portion 18b of the unlocking lever 18 that extends slightly from the rear end of the base member 11 is moved forward by, for example, 0.3 mm to 0.5 mm. Push slightly to the extent. By this push, the slide member 17 is unlocked (unlocked). Then, the slide member 17 moves in the card discharge direction by the elastic force of the coil spring 19. At the same time, the IC card 100 that abuts against the card abutting portion 17 b of the slide member 17 is also discharged rearward from the card accommodating space 13. At that time, the slide member 17 is prevented from jumping out of the card accommodation space 13 by the rear wall 11 e of the base member 11.

  The IC card 100 is detached from the card connector 10 by picking up the rear end of the IC card 100 ejected rearward. After the card is attached / detached, the slide member 17, the lock release lever 18 and the like are returned to the initial positions by the action of the coil spring 19.

  Next, the lock / unlock in the eject mechanism 16 will be described in detail with reference to FIGS. As described above, when the rear end portion 100a of the IC card 100 is pressed against the bias of the coil spring 19, the groove wall 17c in the tip region of the slide member 17 inserted together with the IC card 100 is locked. The spring piece 20 is pushed upward. Furthermore, when the slide member 17 is inserted beyond the position of the engaging portion 17d, the locking spring piece 20 that has been elastically displaced upward returns to the initial position below. When the pressing of the rear end portion 100a of the IC card 100 is stopped, the slide member 17 is slightly retracted in the card ejection direction by the elastic bias of the coil spring 19. The engaging portion 17 d of the slide member 17 is locked at the tip of the locking spring piece 20 while receiving the elastic force of the coil spring 19.

  In this way, the slide member 17 and the IC card 100 are locked as shown in FIG. In this locked state, as described above, the engaging portion 17d of the slide member 17 is engaged and locked with the tip of the locking spring piece 20 while being biased in the card ejection direction by the coil spring 19. The Further, the protrusion 18 a of the lock release lever 18 protrudes upward from the opening 20 a of the locking spring piece 20.

  Next, in unlocking the slide member 17 and the IC card 100, as shown in FIG. 7, the push portion 18b of the lock release lever 18 is slightly pushed in the card insertion direction. By this push, the protrusion 18a of the lock release lever 18 moves forward, and the lock spring piece 20 is elastically displaced upward. Then, the engaging portion 17d of the slide member 17 is disengaged from the tip of the locking spring piece 20, and the locking is released. In the elastic displacement of the locking spring piece 20 by the push of the lock release lever 18, the edge of the opening 20a slides smoothly along the first inclined surface 181a.

  After the unlocking, the slide member 17 moves in the card discharge direction by the bias of the coil spring 19 as described above, and discharges the IC card 100 from the card accommodation space 13 to the rear. Then, the slide member 17, the lock release lever 18, etc. return to their initial positions by the action of the coil spring 19. Here, the lock release lever 18 returns to the initial position when the stopper portion 18e is pushed in the card discharge direction at the rear end of the coil spring 19, for example.

  In the present embodiment, in the card connector provided with the eject mechanism, the eject mechanism has a slide member that reciprocates in the insertion / extraction direction of the IC card, and a spring member that biases the slide member in the card ejection direction. A part of the upper wall of the cover member constituting the housing of the card connector is cut and raised downward to form a locking spring piece for locking the slide member. The lock of the slide member is released by elastically displacing the lock spring piece upward by the lock release member.

  For this reason, in the card connector according to the present embodiment, the lock mechanism for locking and holding the slide member in the card accommodation space becomes extremely simple. Further, the lock spring piece is formed by integral processing of the cover member, and the number of parts of the eject mechanism is reduced. The slide member and the unlocking member can be miniaturized while maintaining the strength thereof, and the eject mechanism can be easily reduced in size and height, and the card connector provided with the same can be further reduced. Miniaturization and thinning are possible. Further, the unlocking member can be easily incorporated into the slide member, and the eject mechanism can be further reduced in size and height. In this way, the conventional limitations in reducing the size and thickness of the card connector are removed.
