Description

  The present invention relates to a card connector which is interposed between a memory card capable of recording predetermined information, such as an IC chip substrate having an IC chip, and an electronic device and enables information transmission between the two.

  An IC chip substrate (referred to as an IC chip card, memory card, etc.) has a structure in which a small IC chip is mounted and can record various information, and is used in various electronic devices and mounted on electronic devices. Information is transmitted to and from the electronic device via the card connector.

  Conventionally, various types of card connectors have been devised as card connectors used in electronic devices. For example, as described in Patent Document 1, an insulating material that holds conductive contacts (contact terminals) is also disclosed. It comprises a base plate (mold) and a card holder that is swingably attached to the base plate. In such a card connector, the IC chip substrate is temporarily attached to the card holder, and the card holder is swung so that the card holder covers the IC chip substrate and holds the IC chip substrate to the contact. The terminal is brought into contact with the contact. In such a card connector of the so-called contact portion pressing method, it is necessary to surely connect the surface terminal of the IC chip substrate and the contact, so the contact is provided with the card holder with the IC chip substrate mounted. The fixed base plate is fastened and fixed with screws or is urged by a biasing means such as a spring. Alternatively, the IC chip substrate is fixed to the base plate by a method in which a fixing means is provided on the base plate without using a card holder and the surface terminal of the IC chip substrate is held by the contact by the fixing means (by the base plate itself). IC chip substrate is also fixed).

JP-A-9-270279

  However, in the method of fixing the card holder to the base plate with the IC chip substrate held against the contact by the card holder, parts such as screws and springs for fixing the card holder to the base plate are required. There is a problem that the number of points increases and the cost of the card connector increases. Further, in the method of fixing the IC chip substrate only by the base plate by providing the base plate with the fixing means without pressing by the card holder, it is necessary to make the surface terminal and the contact of the IC chip substrate conductive. There is a problem that the structure of the fixing means provided on the base plate is complicated in order to prevent the IC chip substrate from being easily detached.

  An object of the present invention is to provide a card connector that can press and hold a memory card on a base plate with a card holder with a simple configuration.

  In order to solve the above-described problems, a card connector according to the present invention includes a rectangular flat plate-like base plate, and can be attached to the base plate so as to cover the upper surface of the base plate and slide back and forth along the upper surface. A card holder to be attached; and a plurality of contacts attached to the base plate and having contact portions protruding upward from the upper surface of the base plate; and a rectangular flat memory card is placed on the upper surface of the base plate and the base plate The card holder is attached to cover the upper surface, and the card side terminal provided on the lower surface of the memory card and the contact portion of the contact are brought into contact with each other. Furthermore, the plurality of contacts are respectively fixed to the base plate, a lead portion integrally connected to one end side of the base portion and extending to the lower surface side of the base plate, and integrally formed to the other end side of the base portion. An arm portion that extends into a slot formed to open on the upper surface side of the base plate and is connected to a distal end side of the arm portion and protrudes upward from the upper surface of the base plate, and In the state where the memory card is placed on the upper surface of the base plate and the card side terminal on the lower surface of the memory card is in contact with the contact portion, the card holder is attached to cover the upper surface of the base plate and When the card holder is pushed down and the memory card is pushed down, the arm part is elastically deformed. The contact portion enters into the slot, and the contact portion is configured to be in press contact with the card side terminal by the elastic deformation force of the arm portion, and further, the plate formed on the left and right side portions of the base plate The plate-side latch in a state where the card holder, which is composed of a side latching part and a holder-side engagement part formed on the left and right side parts of the card holder and covers the upper surface of the base plate, is pushed down And a holder holding portion for locking the card holder and preventing the card holder from moving upward.

  In the card connector configured as described above, preferably, the plate-side locking portion is formed in a protruding shape extending in the front-rear direction, and has a plate-side locking surface on the lower surface, and the holder-side locking portion extends in the front-back direction. The plate-side locking portion when the memory card is mounted on the top surface of the base plate and the card holder is attached to cover the top surface of the base plate. And the holder side latching part is displaced forward and backward, the holder side latching part moves downward without interfering with the plate side latching part, and slides back and forth while pushing down the card holder. As a result, the holder side locking portion is positioned below the plate side locking portion, and when the card holder is released, the holder side locking surface is moved forward. Configured to lock held engaged with the plate side retaining surface and prevents upward movement of the card holder.

  Further, in the card connector configured as described above, preferably, the holder side locking surface is formed to have a taper extending obliquely upward in the engagement slide moving direction, and the plate side locking surface is engaged slide moving. The card holder is formed with a tapered surface extending obliquely downward toward the direction, and receives the elastic deformation force of the arm portion, and the card holder receives a force in the upward movement direction through the memory card, thereby the holder side A force in a direction that strengthens the engagement between the locking portion and the plate-side locking portion is configured to act.

  Further, in the card connector configured as described above, preferably, an opening that penetrates vertically is formed in the card holder, and the card holder is placed on the upper surface side of the base plate through the opening in the state of lying down on the upper surface of the base plate. A planar adsorbing portion exposed toward the surface is formed.

  The card connector according to the present invention has a simple structure because the card holder can be fixed to the base plate without using a fixing member such as a screw or a spring. In particular, the arm portion constituting the contact extends into the slot so that it can be elastically deformed, the tip of the arm portion protrudes upward from the upper surface of the base plate, and the memory card is placed on the upper surface of the base plate to place the card on the lower surface of the memory card. With the side terminal and the contact portion in contact with each other, simply mounting the card holder covering the upper surface of the base plate, pushing it down and pushing down the memory card, the arm portion is elastically deformed and the contact portion is Since the contact portion enters the slot and presses and contacts the card side terminal due to the elastic deformation force of the arm portion, the configuration for holding the memory card and electrically connecting the terminals can be simplified. The card connector further includes locking and holding means composed of plate side locking portions formed on the left and right side portions of the base plate and holder side engaging portions formed on the left and right side portions of the card holder. The structure is such that the plate-side locking portion and the holder-side locking portion are locked with each other in a state where the card holder attached to cover the upper surface of the base plate is pushed down, and the card holder moves up. Simple.

  In the card connector configured as described above, preferably, when the card holder is attached so as to cover the upper surface of the base plate on which the memory card is placed, the plate side latching portion and the holder side latching portion are positioned so as to be displaced forward and backward. The holder side locking portion moves downward without interfering with the plate side locking portion, and the holder side locking portion is positioned below the plate side locking portion by sliding the card holder back and forth while pressing down. When the depression of the card holder is released, it is preferable that the holder side locking surface engages with the plate side locking surface to prevent the card holder from moving upward and hold the card holder. It is possible to simplify the locking and holding structure and easily perform the locking and holding operation.

  Further, in the card connector configured as described above, the holder side locking surface has a taper extending obliquely upward toward the engagement slide movement direction, and the plate side locking surface extends diagonally downward toward the engagement slide movement direction. If formed so as to have a tapered surface, the card holder receives a force in the upward movement direction via the memory card in response to the elastic deformation force of the arm portion, so that the holder side locking portion and the plate side locking portion It can be configured that the force in the direction of strengthening the engagement acts and the engagement of the cover member is difficult to be released. For this reason, it is difficult for the cover member to be released from the base plate against vibrations and impacts applied to the card connector as when the card connector is dropped. That is, the card connector according to the present invention has a simple structure, while suppressing the manufacturing cost of the card connector, the substrate such as an IC chip substrate (memory card) attached to the card connector is not easily detached. Therefore, it can be said that it is excellent in consideration of reliable continuity between the substrate and the contact while considering the cost.

  Further, the card holder constituting the card connector according to the present invention has an opening that penetrates vertically in the state of lying down, and a planar shape that is exposed through the opening in the state of lying down on the upper surface of the base plate. If the suction surface exposed through the opening is directly sucked to the automatic mounting machine with the card holder placed on the base plate in a lying posture, the card connector is connected to the wiring board. It can be mounted on the desired or arbitrary position above. As described above, according to the present invention, it is not necessary to separately attach accessory parts such as a suction pad, which has been conventionally required for automatic mounting by an automatic mounting machine. is there.

The figure is shown. In the embodiment, for convenience of explanation, description will be made by defining front and rear, left and right, and top and bottom, as indicated by coordinate axes and directions in FIG. 1. However, when explaining the shape of the card holder 20, The direction that coincides with the coordinate axes shown in FIG. 1 in the lying posture in which the holder 20 has fallen on the base plate 10 will be described by defining front and rear, left and right, and top and bottom.

  The card connector 1 includes a base plate 10 having a rectangular flat plate shape, a card holder 20 supported on the base plate 10 so that a rear end thereof can swing and slide, and a plurality of contacts 30 press-fitted and fixed to the base plate 10. As shown in FIG. 1, a rectangular flat plate IC chip substrate 80 on which an IC chip 81 as shown in FIG. 2 is mounted is mounted on the base plate 10 in an unfolded posture with the card holder 20 opened with respect to the base plate 10. The surface terminal 82 provided on the IC chip substrate 80 and the contact 30 are brought into contact with each other in the closed posture in which the card holder 20 is fallen down so as to cover the upper surface of the base plate 10 and closed. It is the card connector of the form made to contact.

  The base plate 10 includes a rectangular flat plate portion 11, shaft support portions 12 and 12 formed on the left and right sides of the rear end side of the plate portion 11, and front holding portions 13 </ b> L and 13 </ b> R formed on the left and right sides of the front end side of the plate portion 11. In order to perform positioning when the card connector 1 is mounted on the circuit board which is formed to project from the lower surface of the plate part 11 and the central projecting parts 14 and 14 erected on the left and right side surfaces 17 and 17 of the plate part 11. Positioning posts 18a, 18a, etc., for example, using an electrically insulating resin material such as liquid crystal polymer (LCP), polyphenylene sulfide (PPS), polyamide imide (PAI) or the like, by the molding means such as injection molding into the shape shown in the figure. It is integrally molded.

  The plate portion 11 is formed with 22 long slot contact slots 11a extending in the front-rear direction of the plate portion 11 and arranged in four rows in the front-rear direction, and the bottom surface of the plate portion 11 is located in front of and behind the contact slot 11a. A groove-like contact holding groove 11b is formed to be recessed from the side end face and hold the contact 30. Further, the plate portion 11 has a substantially rectangular shape in a plan view for adsorbing an automatic mounting machine that is automatically mounted on the board and is located at a position where the front and rear are sandwiched by the contact slots 11a and 11a. A flat suction portion 15 is formed.

  The central overhanging portion 14 is formed so as to protrude sideways in an inverted L shape from the plate portion 11, and a portion extending in the shape of an arm in the front and rear direction and slightly obliquely below the side surface of the plate portion 11 is a holder described later. The plate side lock arm 14m which can latch the side lock arm 22m is comprised. A locking portion 16 that protrudes in a substantially rectangular shape in a side view from the side surface of the plate portion 11 is formed at the lowermost portion of the side surface of the plate portion 11 in front of the central projecting portion 14.

  Plate-side taper surfaces 13h and 13h that are inclined obliquely downward toward the rear are formed at the rear portions of the bottom surfaces of the front support portions 13L and 13R. The plate-side taper surfaces 13h and 13h are formed on a card as will be described later. The holder 20 can contact the holder-side tapered surfaces 22h and 22h formed on the upper surfaces of the protruding end portions 22L and 22R of the side surface portions 22 and 22 that are formed to extend toward the front end side.

  The contact 30 is formed at a base 31 fixed to the contact holding groove 11b, a contact arm 32 bent upward from the base 31 and once folded downward, and then extending obliquely upward, and a tip of the contact arm 32. And an upwardly projecting arc-shaped contact portion 33 and a lead portion 34 bent downward and horizontally from the base portion 31 and extending in the opposite direction to the contact arm portion 32. For example, beryllium copper or spring stainless steel A thin plate of a conductive metal material such as steel is processed and formed by a forming means such as a fine blanking press (precision punching process) to form the shape shown in the figure.

  Each contact 30 is inserted into a contact slot 11a from a contact holding groove 11b formed in the lower portion of the plate portion 11 so as to extend back and forth, and a base portion 31 is press-fitted into the contact holding groove 11b and attached to the base plate 10. When the base 31 is fixedly held in the contact holding groove 11b, the contact 30 acts like a leaf spring in which the contact arm portion 32 protruding into the contact slot 11a is cantilevered, and the contact portion 33 at the tip of the arm moves up and down. It is supported so as to be swingable and displaceable in the direction.

  For this reason, the contact portion 33 is positioned so as to protrude from the contact slot 11a to the upper surface of the plate portion 11 when no load is applied. However, when pressed from above, the contact arm portion 32 is elastically deformed and swings downward. The lead portion 34 bent downward and horizontally folded from the base portion 31 accommodated so that the entire contact arm portion 32 including the contact portion 33 is pushed down into the contact slot 11a is formed on the plate portion 11 in the contact mounting posture. The lead 34, which is positioned at substantially the same height as the lower surface and is aligned with the circuit pattern of the mounting board by the positioning posts 18a and 18b protruding from the lower surface of the plate part, is soldered to the circuit pattern on the board (surface mount). )

  The card holder 20 is attached to the base plate 10 so that the rear end thereof can swing up and down, and has a rectangular flat plate-shaped cover portion 21 having an opening 23 formed in a substantially rectangular shape at a substantially central portion, and the cover portion 21. The side portions 22 and 22 are bent downward from the left and right ends of the plate and extend in the form of a plate before and after, and are integrally molded by injection molding or the like using the same resin material as the base plate 10.

  A notch 26 is formed which is located slightly rearward of the substantially central portion in the front-rear direction of the side surface portion 22 and is vertically cut out in a substantially U-shaped cross section from the inner wall side to the outer wall side of the side surface portion 22. Yes. By this cutout portion 26, a thin portion 27 where the thickness of the side surface portion 22 is thinner than other portions is partially formed. In addition, the notch part 26 and the thin part 27 are formed in both the left and right side parts 22. The lower part of the rear surface of the cutout part 26 is inclined obliquely downward to the rear, and the upper part of the rear surface of the cutout part 26 extends vertically at a position retracted rearward from the lower part of the rear face. 26 is formed with a holder-side lock arm 22m that is aligned with the central overhanging portion 14 of the base plate 10 and protrudes forward of the side surface portion 22. Further, the side surface portion 22 is located slightly rearward of the notch portion 26 and the lowermost portion of the side surface portion 22 is cut out in a substantially semicircular cross section (see FIG. 9), and can be engaged with the locking portion 16. An engaging portion 28 is formed. The engaging portion 28 is formed on any of the left and right side portions 22.

  The rear end portion of the cover portion 21 is separated from the cover portion 21 and is formed with arm portions 24 and 24 extending rearward in an arm shape. Circular shaft portions 25, 25 are formed (see FIG. 6). The shaft portions 25, 25 are respectively engaged with groove portions 29 formed in the shaft support portions 12, 12 of the base plate 10, so that the card holder 20 moves up and down with respect to the base plate 10 with the shaft support portions 12, 12 as the swing center. When the card holder 20 is swung downward (in the direction of arrow A in FIG. 6) to the lying posture, the base plate 10 is covered from above.

  On the other hand, when the card holder 20 is swung upward from the state of the lying posture in the direction opposite to the arrow A with the shaft portion 25 as the rocking center, the card holder 20 has the base plate 10 as shown in FIG. Swings to an angle of 90 ° or more. By doing so, since the card holder 20 does not get in the way when the IC chip substrate 80 is placed on the base plate 10 or removed from the base plate 10, the mounting of the IC chip substrate 80 on the card connector 1 and Easy to remove.

  When the card holder 20 is in the lying posture and covers the base plate 10 from above, the suction formed on the upper surface of the plate portion 10 of the base plate 10 through the opening 23 formed in the cover portion 21 of the card holder 20. Part 15 is exposed. The suction portion 15 is formed to suck a suction member (for example, an air nozzle) that is provided in the automatic mounting machine and sucks and holds the card connector. For this reason, unlike the conventional case, if the suction member of the automatic mounting machine is directly sucked to the suction portion without separately providing a suction pad for sucking the suction member, the card connector 1 is desired on the circuit board or It can be mounted at an arbitrary position.

  A shaft support space for receiving the shaft portions 25, 25 is formed in the shaft support portions 12, 12 on the side of the base plate 10 that receives and supports the left and right shaft portions 25, 25 by groove portions 29, 29. The shaft portions 25, 25 can be moved back and forth as guided by the groove portions 29, 29 in the shaft support space (the state located rearward in FIG. 6 is indicated by a dotted line and is located frontward). Is indicated by a chain line). For this reason, the card holder 20 pivotally supported by the pivotal support portion 12 is moved forward in a lying posture with respect to the base plate 10, so that the card holder 20 is moved to the base plate 10 while remaining in the lying posture. It is possible to move it forward. That is, the card holder 20 can swing up and down (open and close) between an unfolded posture opened with respect to the base plate 10 and a lying posture closed on the base plate 10 so as to cover the contacts 30, 30,. In addition, the card holder 20 is slidable back and forth in a lying posture substantially parallel to the base plate 10.

  In order to mount the IC chip substrate 80 on the card connector 1 under the configuration of the card connector 1 as described above, first, the IC chip substrate 80 is mounted on the base plate 10 in an unfolded posture in which the card holder 20 is unfolded upward. Let me put it. Next, the card holder 20 is laid down so as to cover the upper surface of the base plate 10 with the shaft portion 24 as the swing center. As shown in FIG. 6, the card holder 20 swings downward (in the direction of arrow A) from the state extending substantially perpendicular to the base plate 10 with the shaft portion 25 as the base end side, as shown in FIG. It becomes a lying posture that extends substantially parallel to.

  Further, the card connector 1 is provided with a locking and holding means for preventing the card holder 20 from swinging upward from the lying posture and locking and holding the card holder 20 in the lying posture. The latch holding means is engageable with the plate-side lock arm 14m formed on the left and right central projecting portions 14 and the plate-side lock arm 14m, and on the holder side formed in the notch portion 26 of the left and right side surface portions 22. The lock arm 22m includes forward holding portions 13L and 13R of the plate portion 10 and protruding end portions 22L and 22R that are formed on the left and right sides of the front end side of the card holder 20 and are locked to the front holding portions 13L and 13R.

  When the card holder 20 is swung from the unfolded position to the lying position, both the lock arms 14m and 22m are located apart from each other in the swing area (open / close swing area) until the card holder 20 is tilted. In the end swing region, the card holder 20 is slid forward, the holder side lock arm 22m and the plate side lock arm 14m are engaged with each other, and the card holder 20 is restricted from swinging upward. . In addition, the card holder 20 slides forward, and the engaging portion 28 of the card holder 20 and the engaging portion 16 of the base plate 10 are engaged, whereby the card holder 20 moves freely in the front-rear direction. regulate.

  Furthermore, in the present invention, the upward swing of the card holder 20 is reliably regulated as follows. As described above, the plate-side tapered surfaces 13h and 13h that are inclined obliquely downward toward the rear are formed on the rear portions of the bottom surfaces of the front support portions 13L and 13R of the base plate 10, respectively. Further, holder-side tapered surfaces 22h and 22h that are inclined obliquely downward toward the rear are formed on the upper surfaces of the projecting end portions 22L and 22R of the side surface portions 22 and 22 that are formed to extend to the front end side of the card holder 20. Has been.

  When the card holder 20 is slid forward in the lying posture, the holder-side tapered surfaces 22h and 22h of the projecting ends 22L and 22R are formed on the front support 13L and the front support portions 13L and 13R and the projecting ends 22L and 22R. It abuts on the plate-side tapered surfaces 13h and 13h of 13R and moves forward so as to be guided by the plate-side tapered surfaces 13h and 13h. In this manner, the front support portions 13L and 13R and the protruding end portions 22L and 22R are engaged with each other with the plate-side tapered surfaces 13h and 13h and the holder-side tapered surfaces 22h and 22h in contact with each other, and the card holder 20 Is controlled to swing in the opening direction.

  As described above, the front support portions 13L and 13R of the base plate 10 and the protruding end portions 22L and 22R of the card holder 20 are slid and moved forward of the base plate 10 while the card holder 20 is swung. The tapered surfaces 22h and 22h are configured to engage with each other so as to be guided by the holder-side tapered surfaces 22h and 22h. Accordingly, the card holder 20 is combined with the above-described locking and holding means including the holder-side lock arm 22m and the plate-side lock arm 14m, and the side surface holding means including the engaging portion 28 of the card holder 20 and the locking portion 16 of the base plate 10.
