Description

Card Connector {CARD CONNECTOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a card connector that enables information transfer between a card capable of recording predetermined information such as a memory card and the like, and an electronic device. It relates to a card connector.

The memory card has a small IC chip inside and can record various kinds of information. The memory card is also used in a small portable device. For example, a small memory card called a subscriber identification module (SIM) card is used as a mobile phone of a global system for mobile communication (GSM) type, and an electronic device or the like is provided via a card connector installed on a board. Information transfer is performed between them.

As a card connector used in portable devices, various types of card connectors have been devised in the past. For example, a card attachment space is provided inside the back cover of the device, and the card is attached so that the surface terminals of the memory card (hereinafter referred to as a card) come into contact with contacts in the attachment space. The thing of the structure which attaches a back cover is known. Although the card connector has such a simple configuration, it is difficult to attach or detach the card. In addition, the card connector can be attached or detached by forcibly contacting the card in a direction orthogonal to the direction in which the contact is extended. In this case, there has been a problem that there is a risk of damaging the surface terminals and contacts.

Therefore, in order to cope with the above problem, the card user does not directly handle the card to make contact with the surface terminal and the contact, but instead attaches the card to the card holder once, and swings the card holder to contact the surface terminal and the contact. The card connector is known.

FIG. 9 (a) shows an example of a card connector having such a card holder. The card holder 120 is pivotally attached to the base plate 110 on which the contact 130 is provided. In order to mount the card 80 to the card connector 100, first, the card 80 is inserted into the card insertion opening while the card holder 120 is opened, and the card holder 120 supporting the card is supported. After lying down in parallel with the plate 110, the card holder 120 is slid to the base plate 110, and the front end of the card holder 120 is engaged with the base plate 110 to lock the base plate 110. . As a result, the card 80 is brought into contact with the contact portion 132 of the contact 130 at an appropriate contact pressure so that the card 80 is engaged on the base plate 110. When the card 80 is removed, the card holder 120 is slid in the opposite direction as when the card 80 is mounted to release the lock. The card holder 120 is opened by the contact pressure of the contact, and the card 80 is turned off. I can pick it up.

9B is a second example of a card connector having a card holder. In the card connector 200, when the card holder 220 is attached to the base plate 210 so as to be swingable, and is closed, the card holder 220 into which the card 80 is inserted is closed with respect to the base plate 210. The lock release button 250 is automatically locked to avoid swinging, and the face terminal 82 of the card 80 is configured to be brought into direct contact with the contact portion 232 of the contact 230 at an appropriate contact pressure. When the card 80 is taken out, the lock release button 250 is pressed to release the lock, and the card holder 220 can be opened by the contact pressure of the contact to pick up the card 80.

In the card connectors 100 and 200 having the above-described configuration, the surface terminal 82 of the card 80 is simply flipped over while the card 80 is inserted into the card holders 120 and 220. Can be brought into direct contact with the terminals 130 and 230 of the base plates 110 and 210.

However, in the case of the card connector shown in Fig. 9 (a), it is not possible to simply hold the card holder in this position by swinging it, and to keep it locked by sliding the card holder with respect to the base plate after swinging. There is a problem that it is necessary and difficult to operate. Furthermore, there is also a problem that if the slide movement is incomplete, the lock may be released in the middle. In the case of the card connector shown in Fig. 9B, this problem is small, but there is a problem that the locking mechanism becomes complicated.

In view of the above problems, the present invention provides a card connector having a configuration such that the card holder can be held in the overturn position (closed position) simply by turning the card holder over and over, and the mechanism for retaining the lock can be simplified. It aims to do it.

In order to achieve the above object, the present invention includes a base plate provided with a contact, a card support space having a card insertion space formed at the front end side, and a card holder whose rear end side is swingable up and down on the base plate. The card connector is constructed, and the card holder is received and supported in the card support space from the insertion outlet in the open posture position where the card holder is swinged upward with respect to the base plate. It is configured to contact the face terminal provided on the card and the contact by swinging to the closed posture closed position. The rear end side of the card holder is configured to be slidably moved forward and backward with respect to the base plate, and the base plate and the card holder are engaged with each other when the card holder is swung upside down to the closed posture, while the card holder is rolled over. A cam mechanism for sliding movement and a stopper holding means for stopping the card holder from swinging to the open position in the closed posture position, and for overturning the card holder to the closed posture position. At this time, the card holder is slidably moved forward with respect to the base plate by the cam mechanism, and held by the latch holding means in the closed posture position.

According to the card connector having such a configuration, the card holder can be held in the closed posture position simply by swinging the card holder from the open posture position to the closed posture position by using a simple configuration provided only by the cam mechanism and the retaining means. Can be. Furthermore, a card connector can be obtained which is easy to install and operate the card.

In the card connector having the above-described configuration, a locking means comprising a plate side protrusion formed on the base plate and projecting to one of the upper and lower sides and a holder side protrusion formed on the card holder and projecting to the other of the upper and lower sides is provided, and the card holder is closed. When the card holder is rolled over to the posture position and the card holder is slid forward with respect to the base plate by the cam mechanism, the plate-side protrusion engages with the holder-side protrusion and moves to the closed position in which the card holder is moved forward by the locking means. It is preferable to comprise so that it may support.

As a result, the card holder is secured to the closed posture position by the locking means when the card holder is swung from the open posture position to the closed posture position and held by the cam mechanism and the retaining means. The card holder can be held, and the card holder can be kept in the closed position even when an external force is applied, such as when the card connector is dropped.

Fig. 1 shows a preferred embodiment of the card connector 1 according to the present invention as a perspective view, and shows a plan view, a side view, and a front view of the card connector 1 in Figs. 2 (a), (b) and (c), respectively. do. In addition, the side sectional view seen from VII-VII shown by the arrow in FIG. 2 (a) is shown in FIG. 7, and the partial cross sectional view seen from VIII-VIII shown by the arrow is shown in FIG. In addition, in this specification, front and rear, right and left are defined and demonstrated so that the coordinate axis and direction may be added in FIG. 1 for convenience of description.

The card connector 1 includes a base plate 10 having a rectangular flat plate, a card holder 20 supported by the base plate so as to be able to swing and slide, and a plurality of contacts 30 press-fitted to the base plate 10. As shown in FIG. 1, the card 80 is accommodated and held in an open position in which the card holder 20 is opened with respect to the base plate 10, and covers the upper surface of the base plate 10. It is a card connector in which the surface terminal 82 provided in the card 80 and the contact 30 are brought into direct contact with each other in the closed posture position closed over.

The base plate 10 is a plate portion 11 of a rectangular flat plate, bearing portions 12 and 12 formed on the left and right sides of the rear end side of the plate portion 11, and an anterior support portion formed on the left and right sides of the front end side of the plate portion 11. 13L, 13R, 0 center elongated portions 14, 14 provided on the left and right sides of the plate portion 11, positioning pins 18a, 18b, etc., which protrude on the lower surface of the plate portion 11, For example, an electrically insulating resin material such as liquid crystal polymer (LCP), polyphenylene sulfide (PPS) polyamide imide (PAI), and the like are integrally formed into the shape shown by molding means such as injection molding.

In the center of the plate portion 11, four long slot-shaped contact slots 11a extending in the front-rear direction of the plate portion 11 are formed side by side in two rows, four contact slots 11a and the plate portion 11, respectively. An ant groove-shaped contact support groove 11b for supporting the contact 30 is formed between the front and rear side cross-sections.

The contact 30 includes a base portion 31 fixed to the contact support groove 11b, a contact arm portion 32 extending from the base portion 31 in an elongated finger shape and partially bent upwardly; A circular arc-shaped contact portion 33 formed at the distal end of the contact arm portion 32 and a lead extending downward from the base portion 31 and bent horizontally and extending in the opposite direction to the contact arm portion 32. It consists of the part 34, for example, is formed into the shape shown by carrying out the shaping | molding of thin plates of electroconductive metal materials, such as a beryllium copper and a stainless steel for springs, by shaping | molding means, such as a fine blanking press.

Each contact 30 is inserted toward the contact slot l1a from the contact support groove 11b formed before and after the plate portion 11, and the base portion 31 is pressed into the contact support groove and inserted into the base plate 10. Attached. When the base part 31 is fixedly supported by the contact support groove 11b, the contact 30 acts like a plate spring in which the contact arm part 32 which protrudes into the contact slot 11a is piece-supported. The contact portion 33 at the tip of the arm is held so as to be swingable in the vertical direction.

For this reason, although the contact part 33 protrudes from the contact slot 11a to the upper surface of the plate part 11 at no load, when the contact part is pressed from the upper side, the contact arm part 32 elastically deforms and fluctuates downwards. The entire contact arm portion 32 including the contact portion 33 is received as if it is pressed into the contact slot 11a and sinks (see FIG. 7). The lead portion 34, which is bent downward and horizontally from the base portion 31, is positioned at approximately the same height as the lower surface of the plate portion 11 in the contact installation position, and has a positioning pin that protrudes from the lower surface of the plate portion ( Lead portions 34 that are aligned with the circuit patterns of the mounting substrate in 18a and 18b are solder-bonded (surface mounted) to the circuit patterns on the substrate.

The card holder 20 has a rectangular flat plate cover portion 21, rear elongated portions 22, 22 formed on the left and right sides of the rear end side of the cover portion 21, and front elongated portions formed on the left and right sides of the front end side of the cover portion 21. It consists of the parts 23 and 23, the stopper 27 and 27 ... which were protruded and formed in the center part of the rear end side of the cover part 21, etc., and is integrally formed using the same resin material as the base plate 10. As shown in FIG.

The front elongated portions 23, 23 provided on the left and right sides of the front end side of the cover part 21 are formed in the shape of "Co" opened on the left and right sides respectively when viewed from the front side, and are inserted from the card insertion hole 26 of the front end. The card 80 is configured to be guided to the side wall surfaces 23a and 23a opposite to the left and right sides and to the support edge portions 23b and 23b provided in parallel with the cover portion 21 so as to be inserted smoothly. In addition, the rear elongated portions 22, 22 provided on the left and right sides of the rear end side of the cover portion 21 are formed with side wall surfaces 22a and support edge portions 22b, like the front elongated portions 23, and the card insertion openings ( The card 80 inserted from 26 is guided to be inserted to the inside of the card holder without tilting.

Stoppers 27, 27... Protrude downward from the back of the card holder 20, and the card 80 inserted into the card holder 20 has its front end (the end of the side inserted into the card holder 20). ) Is positioned in the card holder 20 by abutting these stoppers 27 in front. In addition, as shown in FIG. 1, a corner portion of the main body portion 81 of the card 80 is provided with a taper portion 81a for clarifying the direction of the card 80. The taper portion 81a is inserted into the card holder 20 in a posture positioned at the rear right side with respect to the insertion direction of the card 80 (in this case, the surface terminal 82 on the bottom side of the card becomes the bottom side in the reverse direction).

The rear ends of the left and right rear elongated portions 22 and 22 are separated from the cover portion 21 and extend in the rear in the shape of arms, and the semi-cylindrical shaft portions 22c and 22c protrude in the left and right sides, respectively, at the distal ends thereof. Is formed.

On the other hand, the bearing portions 12, 12 on the side of the base plate 10, which accommodates and supports the left and right shaft portions 22c, 22c, show the partial cross-sectional view seen from VIII-VIII indicated by the arrow in Fig. 2A. In addition to the positional change of the holder 20, as shown in Figs. 8 (a), (b), and (c), the slide restricting surfaces 12a and 12b formed before and after, the convex cylindrical surface 12c, and 12 d of avoidance surfaces for smoothly connecting between the front slide restricting surface 12a and the cylindrical surface 12c, and the storage space 12s surrounded by their respective surfaces and opened to the lower side and the left and right outside. ) Is formed. Between the rear slide restricting surface 12b and the cylindrical surface 12c, a card holder mounting hole having a “co” shape open to the left and right in a plan view is formed (see FIG. 2 (a)), and the shaft portion on the card holder side. 22c is press-fitted above the mounting opening in a mounting position in which the card holder 20 is vertical (an attitude in which the flat surface of the shaft portion 22c abuts on the cylindrical surface 12c), and is inserted into the storage space 125. do.

In the storage space 12s, the cylindrical surface 12c convex downward and the shaft portion 22c convex upward are opposed to each other so that the cylindrical surfaces abut each other. Moreover, the space | interval of the slide control surface 12a, 12b before and after in the storage space 12s is set larger than the diameter of the shaft part 22c, and the shaft part 22c can move back and forth in this storage space 12s. have. For this reason, the card holder 20 is closed on the base plate 10 so that the open posture position opened with respect to the base plate 10, and the cover portion 21 covers the contacts 30, 30, ... from above. It can swing up and down between the closed posture positions.

In this way, the central elongated portion 14 protruding upward from the plate portion 11 between the front elongated portion 22 and the rear elongated portion 23 of the card holder 20 supported by the swingable and slidably movable. And the cutout is cut out, and the locking mechanism (lock means) is provided between the rear part of the central extension part 14 and the front part of the rear extension part 22, and the front part of the central extension part 14 A cam mechanism (guide mechanism) is provided between the rear portions of the front elongated portion 23.

The lock mechanism consists of a plate side lock arm 14m formed at the rear of the left and right center elongated portions 14 and a holder side lock arm 22m formed at the front portion of the rear elongated portion 22. The plate-side lock arm 14m is formed by forming a downwardly convex arc-shaped protrusion on the rear end side of the arm portion projecting backward from the rear upper portion of the central elongated portion 14, and the holder-side lock arm 22m is rear-loaded. An upwardly convex circular arc-shaped projection is formed on the front end side of the arm portion protruding forward from the front lower portion of the portion.

The rock arms 14m and 22m on both sides are the swing region (opening / closing swing region) until the middle of the card holder 20 when the card holder 20 swings from the open position to the closed position as described below based on FIGS. 5 and 6. In the end swing zone (cam operation zone) in which the card holder 20 is moved to the closed posture position, and slides forward while swinging by the action of the cam mechanism, and the circular arc of the holder side lock arm 22m. The projections are moved so as to cross the arc-shaped projections of the plate-side lock arm 14m and engaged with each other, and the card holder 20 is freely moved forward and backward. Further, in the engaged state, the card holder 20 is restricted from swinging in the opening direction by the arm portions which are combined up and down.

In addition, when the card holder 20 slides forward while rocking as described above, the shaft portion 22c of the card holder 20 is formed in the cylindrical space 12s in the storage space 12s of the base plate 10. It is moved up to the position which contacts the front side slide control surface 12a over (refer FIG. 8 (c)). In the state where the card 80 is attached to the card holder 20, the whole card holder 20 is urged upward by the force of the spring of the contact 30, and the shaft part 22c of the upper and lower cylindrical surfaces which contact | connect each other is carried out. It is urged forward by an action, and is positioned so that it may fit between the cylindrical surface 12c and the front slide restricting surface 12a. For this reason, the free movement of the card holder 20 in the front-rear direction is also regulated here, and firm support is made against the impact in the front-rear direction and the vertical direction.

The cam mechanism is formed on the front edges of the left and right central elongated portions 14, and the first cam surface (guide) having an inclined shape that descends obliquely from the upper end surface of the central elongated portions 14 toward the base plate 10. Cotton, 14f). On the card holder 20 side, a second cam surface (slide surface) 23f having a slope is formed on the rear edge portion of the front elongated portion 23 downward, and on these first and second cam surfaces 14f and 23f. This constitutes a cam mechanism. Therefore, when the card holder 20 is swung upside down to the closed posture, the second cam face 23f abuts on the first cam face 14f and slides on this face, and the card holder 20 rolls over and shakes the base. Guide the slide to move forward of the plate (10). In addition, the operation | movement at this time is mentioned later.

The front support part 13L, 13R is provided in the front-end part of the base plate 10, and the front support part 13L, 13R is protruded, and each bottom face part protrudes the support edge part 23b, 23b which protruded and extended in the front-end side of the card holder 20. Supporting grooves 13h and 13h are formed to receive the ends 23h and 23h. As can be seen from this, the locking holding means for preventing the card holder 20 from swinging in the open posture position (upward direction) by the protruding ends 23h and 23h and the support grooves 13h and 13h is constituted. do. In this way, the support holder 13h on the base plate 10 side and the protruding end 23h on the card holder 20 side overturn the card holder 20, and the card holder 20 has the first cam surface 14f. The projecting end 23h of the card holder is guided and inserted into the support groove 13h of the base plate while being slid and moved in front of the base plate 10 while being continuously guided. As a result, the card holder 20 is reliably supported so as to not swing in the opening direction together with the above-described locking mechanism.

The left front support part 13L of the left and right front support parts 13L and 13R is provided with a card support wall 13La which faces the front end surface of the card 80 supported in the closed posture, and the right front support part 13R. ) Is provided with a card support wall 13 (Ra) which opposes the tapered portion 81a formed at the right angled portion of the card 80 supported by the card holder 20. These card support walls 13L and 13R support the card 80 in the front-rear direction between the stoppers 27, 27 on the rear end of the card holder in the closed posture position where the card holder 20 is closed. When the impact force acts in the direction, the card 80 sliding and sliding at the reaction force is abutted to prevent the card 80 from falling off.

In addition, the cover portion 21 positioned directly above the contact portion 33 of the contact in the closed posture position of the card holder 20 has a long hole shape penetrating the front and back corresponding to each contact 30, 30. The hole parts 21a, 21a ... are provided (see FIG. 1). For this reason, for example, when the card connector 1 is attached to the board | substrate of an electronic device, and a functional test is carried out, the card holder 20 is closed and the card holder 20 is closed, without inspection. The inspection probe can be inspected by contacting the contact portions 33, 33... Through the hole portion 21a from the upper portion, and, for example, the contact 30 is press-fitted exactly as the number of pins according to the specification. It is possible to optically inspect whether or not the card is installed or whether the card 80 is mounted.

Next, the order and operation of each part when the card 80 is installed in the card connector 1 configured as described above will be described with reference to FIGS. 3 to 6. 3 (a) and 3 (b) show a procedure until the card 80 is inserted into and supported by the card holder 20 in the state in which the card holder 20 is opened. 3 (b), the mounting procedure after the card holder 20 supporting the card 80 is overturned on the base plate 10 is shown. 4 and 5, the description of the card 80 is omitted.

When installing the card 80, first, the front end portion of the card 80 is inserted in parallel with the cover portion 21 at the card insertion opening 26 in the open posture position in which the card holder 20 is opened upward (Fig. 3). (a)). The card 80 is guided to the side wall surfaces 23a and 23a and the support edge portions 23b and 23b of the left and right front elongated portions to be guided smoothly into the card holder, and furthermore, the side wall surfaces 22a and 22a and the support edges of the rear elongated portion. Guided to (22b, 22b) so as not to be inclined to the inside of the card holder, the front end surface of the card 80 is supported by the card holder 20 at a position abutting the guides 27, 27 (Fig. 3 (b) )).

Subsequently, the card holder supporting the card 80 is rolled over so as to cover the surface of the base plate 10 with the shaft portion 22c as the swinging center, as shown by the arrow in FIG. 3 (b). In the overturning process, first, as shown by ① to ⑦, the card holder 20 is in a closed position in a state located behind the axial support space 12s in the axial support space 12s (Fig. 8 (a)). Rolled over to the position. At this time, the movement trace A of the front end position of the card holder 20 and the movement trace B of the holder-side lock arm 22m are shown in Fig. 6, and the first and second cam surfaces are shown in this swing region. 14f and 23f are separated, and the locus | trajectory which swings around the shaft part 22c of the substantially fixed state is drawn, and this is called an opening / closing swing area | region.

As shown in detail in FIG. 5, when the card holder 20 swings open and close to the position shown in (8), the second cam surface 23f contacts the first cam surface 14f, and at this time, the card holder 20 is opened. The pushing force acts in the abutment normal direction of both the cam faces 14f and 23f, and the card holder 20 slides forward. As a result, the front end position of the card holder 20 and the position of the holder side lock arm 22m are slid forward while swinging downward as shown by lines A and B in FIG. The swinging region to which the slide is moved is called a cam operating region).

As a result, when the card holder 20 is rocked to the fully closed position as shown in FIG. 9, the protruding end 23h of the card holder 20 enters the support groove 13h of the base plate 10. As shown in FIG. The plate side lock arm 14m and the holder side lock arm 22m are engaged, and the card holder 20 is firmly supported in this closed position. At this time, the shaft portion 22c moves forward in the shaft support space 12s.

As can be seen from this, only the card holder 20 is pushed down from the open posture position to the closed posture position, and the card holder 20 is moved downward by the action of the cam mechanism. The slide moves forward while rocking toward the front, the front and rear slides are blocked by the locking mechanism, and the protruding end 23h of the card holder 20 enters the support groove 13h of the face plate 10 to stop the swinging up and down. do.

In addition, when removing the card 80 mounted in this way, the card holder 20 is pushed downward to slide backward to release the lock holding by the left and right locking mechanisms, and to support the projecting end 23h. The engagement of the groove 13 is released. When the engagement of the protruding end 23h and the support groove 13 is released, the card holder 20 rises upward by the spring force of the contact 30. Next, the card holder 20 swings upward to expand. The card 80 may be removed quietly.

Although preferred embodiments of the present invention have been described so far, the scope of the present invention is not limited to the above-described examples. For example, in the above embodiment, the swinging point of the card holder is slidably moved back and forth with respect to the base plate, and the shaft portion 22c provided in the card holder 20 is provided in the storage space 12s provided in the base plate 10. Although the form to be supported was illustrated, on the contrary, the structure which provides the shaft part in the base plate side, and the groove part which supports the shaft part so that a slide movement can be provided in the card holder side may be sufficient.

Moreover, although the cam mechanism which slides a card holder forward and slides forward is comprised by the base plate and the 1st and 2nd cam surface formed in the middle part of the card holder, the cam mechanism which has the same function is provided in the shaft part 22c. You may also do it.

Further, as an example of the locking means, the locking mechanism of the form in which the plate-side lock arm 14m provided in the base plate 10 and the holder-side lock arm 22m provided in the card holder 20 are combined up and down is exemplified. The lock mechanism of the form combined in the left-right direction may be sufficient. Moreover, although the structure by which the protrusion (protrusion end 23h) provided in the card holder 20 was penetrated into the puddle (supporting groove 13h) provided in the base plate 10 was illustrated, the card holder 20 is reversely opposed to this. The puddle provided in the) may be configured to penetrate the projection provided on the base plate 10.

In addition, in the present specification, for convenience of description, the front and rear, left and right directions are defined as illustrated in FIG. 1 for adding the coordinate axes. However, these directions define the orientation of the card connector body and the installation posture when installed on the board. Instead of changing the attitude of looking at the connector, even if the names of the front, rear, left and right have been changed, it is not affected. In the embodiment, the SIM card is exemplified as an example of the card-shaped recording medium. However, the format and size of the card are not limited to the card, but other types of card-shaped recording media can be similarly configured to obtain the same effect. .
