Description

  The present invention relates to an IC card connector including a tray member on which an IC card is detachably disposed.

  In electronic devices such as mobile phones, a central processing unit (CPU) or an IC card such as a SIM (subscriber identity module) card with a built-in memory integrated circuit can be attached to and detached from each device via an IC card connector. By attaching to the device, various function expansions and the like in the electronic device are performed.

  An IC card connector on which an IC card such as a SIM card is mounted is arranged on a wiring board in the electronic device. The IC card connector includes, for example, a contact terminal group that electrically connects the IC card and the wiring board, and a tray member on which the IC card is mounted, as also disclosed in Patent Document 1 and Patent Document 2. ing. The tray member is disposed so as to be slidable with respect to the card housing portion in the IC card connector.

  At that time, when the tray member is slid with respect to the card accommodating portion and then accommodated, it is required that each contact pad of the mounted IC card abuts against the contact portion of each contact terminal. . Therefore, such a tray member is guided and positioned in the card housing portion by the concave and convex portions as positioning means formed on the tray member and the card housing portion, respectively.

  For example, as shown in Patent Document 2, the uneven portion is a guide groove formed on the outer surface of the bottom of the tray member along the thickness direction of the IC card to be mounted, that is, the thickness direction of the tray member. And a protrusion formed on the bottom wall portion forming the card accommodating portion corresponding to the guide groove.

  In an electronic device such as a cellular phone that is relatively miniaturized, the IC card connector is required to have a lower profile. The plate thickness tends to be thinner.

JP 2007-193733 A Japanese Patent No. 4138765

  As described above, when the concave and convex portion as the tray member positioning means is provided in the tray member and the card housing portion so as to protrude along the thickness direction of the tray member, the low profile of the IC card connector is reduced. It is conceivable to reduce the thickness of the tray member or the like as desired.

  However, by reducing the thickness of the tray member along the thickness direction, it is possible to reduce the height of the tray member in the case where the positioning means including the above-described uneven portions is provided. is there. Therefore, it may be difficult to further reduce the height of the IC card connector.

  In view of the above problems, the present invention is an IC card connector including a tray member on which an IC card is detachably disposed, and positioning means for contact terminals of contact pads of the IC card mounted on the tray member It is an object of the present invention to provide an IC card connector capable of further reducing the height of the IC card connector.

  FIG. 2 shows the appearance of an example of an IC card connector according to the present invention.

  The IC card connector shown in FIG. 2 includes, for example, an electrode portion of a memory card SC that is detachably accommodated in a later-described tray member and a connection terminal portion of a wiring board that is arranged inside a predetermined electronic device. It shall be electrically connected. The IC card connector is arranged inside an electronic device such as a mobile phone, a telephone, a PDA, or a camera. The thin-plate memory card SC is, for example, a SIM card, and a plurality of electrode pads are formed on one surface portion corresponding to the arrangement of contact terminals described later (see FIG. 4).

The IC card connector forms a housing part for the memory card SC and the tray member in cooperation with the base member 12 in which a plurality of contact terminals for electrical connection to the memory card SC to be accommodated are arranged Cover member 10 and a tray member 16 on which a memory card SC is detachably mounted.

  The cover member 10 is made of a metallic thin plate material, for example, a stainless steel plate, and has a plurality of through holes 10d at predetermined intervals on both side walls. Claw portions 12d (see FIG. 3) formed on both side walls of the corresponding base member 12 are engaged with the plurality of through holes 10d. Thereby, the cover member 10 and the base member 12 are integrated and combined. At that time, a card slot through which the tray member 16 and the memory card SC pass is formed at the opening end of the cover member 10.

  Further, a locking leaf spring 10LS is integrated with the cover member 10 between the through hole 10d formed at the end on the card slot side of one side wall portion of the cover member 10 and the adjacent through hole 10d. Is formed. When the tray member 16 is operated, the distal end portion of the locking leaf spring 10LS is selectively engaged with locking grooves 16Ld and 16Le as engaged portions formed on the side wall portion 16LW of the tray member 16. To do.

  A similar locking leaf spring 10LS is integrated with the cover member 10 between the through hole 10d formed at the end of the other side wall of the cover member 10 on the card slot side and the adjacent through hole 10d. Is formed. When the tray member 16 is operated, the distal end portion of the locking plate spring 10LS is selectively engaged with locking grooves 16Rd and 16Re as engaged portions formed on the side wall portion 16RW of the tray member 16. To do.

  The card / tray member accommodating portion into which the memory card SC and the tray member 16 are inserted and accommodated is formed as an internal space surrounded by the cover member 10 and the base member 12, as shown in FIG.

The base member 12 forms the bottom of the card / tray member accommodating portion described above.
The base member 12 includes a contact support 14 that supports the contact terminal 20ai (i = 1 to n, n is a positive integer), and guide groove formations that are integrally coupled to both sides of the long side of the contact support 14 respectively. And a member.

  As shown in FIG. 3, each guide groove forming member is made of a metal thin plate material, for example, a stainless steel plate, and a plurality of claw portions 12 d are formed on a side wall portion formed by being bent substantially vertically from the bottom portion. Are formed at predetermined intervals. Each claw portion 12d is engaged with a corresponding through hole 10d in the cover member 10 described above. Further, a cutout portion is formed in the side wall of the cover member 10 at a position corresponding to the locking leaf spring 10LS.

  As shown in FIG. 3, the rectangular thin plate-like contact support 14 is insert-molded together with the contact terminals 20ai (i = 1 to 6), for example, with a resin material. Position regulating end faces 14ER and 14EL for positioning and guiding the peripheral edge of the opening of the tray member 16 to be described later are arranged at the end of the contact support 14 to which the end of each guide groove forming member is coupled. It is formed substantially in parallel.

  In the contact support 14, the contact terminals 20ai are arranged to correspond to the arrangement of the plurality of electrode pads of the memory card SC described above.

  The contact terminal 20ai is in contact with the electrode pad of the memory card SC and electrically connects the memory card SC and a wiring board (not shown). Each contact terminal 20ai is made of a sheet metal material and has the same structure. The contact terminal 20ai includes a movable piece portion having a contact portion that is in contact with and electrically connected to the electrode pad of the memory card SC, a soldered terminal portion that is soldered and fixed to the conductive layer of the wiring board, a movable piece portion, The fixing part is connected to the soldered terminal part. The fixing portion is fixed integrally with the contact support 14. Thereby, the contact portion of the movable piece having elasticity can be elastically displaced in a slit formed at a predetermined position on the contact support 14. For example, two rows of slits formed at a predetermined interval on a common straight line are formed in three rows corresponding to the movable piece portions of the contact terminals 20ai.

  As shown in FIG. 1, the tray member 16 is formed of, for example, a resin material, and has a card storage portion 16A in which the memory card SC is detachably stored. The card accommodating portion 16A includes a first bottom surface portion 16BR and a second bottom surface portion 16BL, and a first bottom surface portion 16BR in a bottom portion 16B slidably disposed on each guide groove forming member in the base member 12. A third bottom surface portion 16BC that connects the front end portion of the first bottom surface portion 16BL and the front end portion of the second bottom surface portion 16BL, side wall portions 16RW and 16LW respectively formed on the first bottom surface portion 16BR and the second bottom surface portion 16BL, It is surrounded by a front wall portion 16W formed on the third bottom surface portion.

  At a portion where one end of the side wall portion 16RW intersects with one end of the front wall portion 16W, a slope portion 16wa is formed to engage a chamfered portion formed at a corner portion of the end portion of the mounted memory card SC. Yes. Further, a notch portion 16wb is formed between the other end of the front wall portion 16W and the end of the side wall portion 16LW in the third bottom surface portion 16BC. A stopper portion 16wc that restricts the amount of movement of the tray member 16 relative to the cover member 10 is formed at the end of the side wall portion 16LW adjacent to the notch portion 16wb. Further, a stopper portion that restricts the amount of movement of the tray member 16 relative to the cover member 10 is formed at a position facing the above-described stopper portion 16wc in the side wall portion 16RW.

  The outer surface portion of the side wall portion 16RW is formed with recesses 16Rd and 16Re that are engaged with the pressing portion of the locking leaf spring 10LS described above at a predetermined interval. Recesses 16Ld and 16Le with which the pressing portion of the leaf spring 10LS is engaged are formed with a predetermined interval.

  Accordingly, the tray member 16 is held at the position shown in FIG. 4 by the elastic force of the pressing portion of the locking plate spring 10LS when the pressing portion of each locking plate spring 10LS is engaged with the recesses 16Rd and 16Ld. As a result, the tray member 16 is easily held without being pulled out through the card slot. Further, the tray member 16 falls out of the card / tray member accommodating portion so that the memory card SC can be easily attached and detached when the pressing portion of each locking leaf spring 10LS is engaged with the recesses 16Re and 16Le. Without being protruded to the maximum.

  The first bottom surface portion 16BR and the second bottom surface portion 16BL are formed substantially parallel to each other along the longitudinal direction of the tray member 16. An opening 16b into which the contact support 14 is inserted is formed in an inner portion surrounded by the first bottom surface portion 16BR, the second bottom surface portion 16BL, and the third bottom surface portion 16BC. As a result, the peripheral portions of the first bottom surface portion 16BR and the second bottom surface portion 16BL forming the opening 16b are positioned in the position of the contact support 14 as shown in FIG. 6 (A). It will be guided by the regulating end faces 14ER and 14EL. Therefore, the tray member 16 to be inserted is guided by the position regulating end surfaces 14ER and 14EL of the contact support member 14, so that the contact portion of the contact terminal 20ai in the contact support member 14 of the memory card SC mounted on the tray member 16 is provided. Is positioned. At that time, the electrode pad of the memory card SC comes into contact with the contact portion of the contact terminal 20ai through the opening 16b.

  Further, a bent portion 16Ba is formed as a pressing means on a part of the periphery forming the opening 16b in the first bottom surface portion 16BR. The bent portion 16Ba is bent at a predetermined angle along the oblique line 16a toward the bottom surface of the guide groove forming member. The oblique line 16a is inclined at a predetermined angle with respect to the peripheral edge forming the opening 16b from the rear end of the first bottom surface part 16BR. Thereby, when the tray member 16 is not inserted into the card / tray member accommodating portion, as shown in FIG. 7, the end surface 16Be of the bent portion 16Ba is not the other portion of the first bottom surface portion 16BR, the second The bottom surface portion 16BL and the third bottom surface portion 16BC protrude below the common plane by a predetermined height DH.

  Therefore, as shown in FIG. 8, when the tray member 16 loaded with the memory card SC is inserted into the card / tray member accommodating portion, the end surface 16Be and the back surface 16BB of the bent portion 16Ba resist the elastic force. Then, it is pressed toward the bottom surface of the guide groove forming member, and is pressed toward the memory card SC so that the end surface 16Be coincides with the position regulating end surface 14ER of the contact support 14 described above. Thereby, the memory card SC and the tray member 16 are pressed against the inner peripheral surface of the cover member 10 by the reaction force generated in the tray member 16, so that the play of the memory card SC and the tray member 16 with respect to the cover member 10 is absorbed. It becomes.

  Further, when the locking grooves 16Rd and 16Ld of the tray member 16 in which the memory card SC is mounted are respectively engaged with the locking leaf spring 10LS, the first force is generated by the elastic force in the locking leaf spring 10LS. A part of the inner edge of the bottom surface portion 16BR and the second bottom surface portion 16BL is pressed along the lateral width (short side) direction of the tray member 16 against the position regulating end surfaces 14ER and 14EL of the contact support 14.

  On the other hand, in the case of the tray member 16 ′ that does not have the bent portion 16Ba as described above, the tray member 16 ′ is formed relatively thin as shown in an enlarged view in FIG. When the bottom portion is provided, play with respect to the cover member 10 of the memory card SC and the tray member 16 is not absorbed, so that the second bottom surface portion rides on the contact support 14, and the memory card SC and the tray member 16 'can be smoothly attached and detached. May become difficult.

  Therefore, in the example of the IC card connector according to the present invention, the tray member can be attached and detached with a relatively small operation force in the configuration having the bent portion 16Ba, and is mounted on the tray member. Since it is not necessary to provide the concave and convex portions as positioning means for the contact terminals of the contact pads of the IC card in the tray member and the card accommodating portion, it is possible to employ the tray member 16 having a relatively thin bottom. Further reduction in the height of the IC card connector can be achieved.

  In such a configuration, when the tray member 16 loaded with the memory card SC is inserted into the card / tray member accommodating portion, the inner edge of the opening 16b of the tray member 16 is positioned at the end surface 14ER for position regulation of the contact support 14 and After being aligned with 14EL, one end is inserted through the card slot. At that time, the tray member 16 is inserted to a predetermined position so that the electrode pad in the memory card SC faces the contact terminal 20ai. Thereby, the memory card SC is urged toward the cover member 10 by the elastic force of the movable piece portion of each contact terminal 20ai.

  On the other hand, when the memory card SC is taken out from the tray member 16, the memory card SC is pulled out against the elastic force of the two locking leaf springs 10LS, and then the memory card SC is inserted into the card accommodating portion 16A of the tray member 16. Taken from.

  In the tray member 16 described above, the shape of the bent portion 16Ba is a substantially triangular shape extending halfway in the longitudinal direction of the first bottom surface portion 16BR. However, the present invention is not limited to such an example. For example, FIG. ) And (B), the shape of the bent portion extends to the end of the first bottom surface portion, or the shape of the bent portion is formed at the rear end of the first bottom surface portion. It may be a substantially isosceles triangle. That is, the shape of the bent portion described above is to suppress the size of the IC card and the IC card connector, the gap (play) between the outer peripheral portion of the tray member and the inner peripheral portion of the cover member, and the gap. It can be appropriately changed according to other factors such as the required reaction force due to the bent portion and the size of the friction coefficient due to the difference in the material of the tray member or the like. As a result, even in other similar IC card connectors, the tray member can be attached and detached with a relatively small operating force in the configuration having the bent portion, and the bottom surface portion of the tray member as described above. The climbing onto the contact support is avoided.
