JP4410273B2 - Memory card connector and portable terminal equipped with the memory card connector - Google Patents

Description

  The present invention relates to a connector for a memory card such as a microSD card and a portable terminal including the memory card connector.

The memory card connector includes a housing having a storage portion that removably receives the memory card, and a slider that slides in the storage portion together with the memory card. On the bottom surface of the storage unit, there are provided a number of contacts that can be electrically connected to the terminals of the memory card inserted into the storage unit. Further, the slider is movable to a non-conductive position where the contact of the memory card and the contact of the housing are not in contact and a conductive position where the terminal and the contact are in contact.
In general, this type of connector is provided with a heart cam mechanism that maintains a conductive state between a memory card terminal and a housing contact by temporarily holding a slider in the conductive position.

The heart cam mechanism includes a cam bar, a support recess that rotatably supports one end of the cam bar, and a heart cam groove that engages the other end of the cam bar so as to be relatively movable.
Since the heart cam groove engages and traces the other end of the cam bar, the heart cam groove is preferably formed as deep as possible. However, in recent years, there is a strict demand for a low profile connector, and when the heart cam groove is formed on the slider, it is difficult to increase the depth of the heart cam groove.
Therefore, in Patent Document 1, a support recess for rotatably supporting one end portion of the cam bar is formed on the upper surface of the slider, and a heart cam groove is formed on the bottom surface of the housing so that the other end portion of the cam bar is movably engaged. Furthermore, the other end of the cam bar is lifted from the heart cam groove so that it does not fall off by pressing the cam bar to the bottom side of the housing with the free end of the leaf spring that is cut and raised in the cover member that closes the ceiling surface of the housing. So that it is not released.)
By forming the heart cam groove on the housing side in this way, the overall height of the connector can be reduced even when the heart cam groove is formed deeper than when the heart cam groove is formed on the upper surface of the slider.
JP 2006-19030 A

In order to prevent the other end of the cam bar from floating from the heart cam groove, the other end (or the vicinity of the other end) of the cam bar, which is the end near the heart cam groove, is pressed against the bottom surface of the housing by a leaf spring. Ideally.
However, in Patent Document 1, when the slider slides, the cam bar also moves relative to the housing and the cover member. Therefore, when the position of the slider changes, the relative position between the free end of the leaf spring and the cam bar changes. Therefore, depending on the position of the slider, the free end portion of the leaf spring presses the center portion or one end portion side of the cam bar.

Furthermore, when the slider is slid together with the memory card from the non-conductive position to the conductive position, the leaf spring is used to facilitate the initial operation of the slider, and to minimize the wear of the heart cam groove and the warping of the bottom surface of the housing. It is ideal to reduce the pressing force due to the pressure to such an extent that the function is satisfactory. On the other hand, to securely hold the slider in the conductive position (to engage the other end of the cam bar with the position E of the heart cam groove) or to obtain a clear click when the other end of the cam bar gets over the step of the heart cam groove For this, it is necessary to increase the pressing force by the leaf spring.
However, in Patent Document 1, regardless of the position of the slider, a substantially constant pressing force is applied from the leaf spring to the cam bar, and it cannot be said that the pressing force is appropriately applied from the leaf spring to the cam bar.

  The object of the present invention is to allow the biasing means to press the portion of the cam bar close to the heart cam groove when the slider is in either the non-conductive position or the conductive position, and to apply an appropriate biasing force to the cam bar according to the position of the slider. An object of the present invention is to provide a memory card connector capable of exerting and a portable terminal including the memory card connector.

The memory card connector according to the present invention includes a housing with an open ceiling surface, the housing having a housing part into which the memory card can be inserted and removed, and a contact electrically connected to a terminal of the memory card inserted into the housing part. The slider slides together with the memory card and can move to a non-conductive position where the terminal and the contact are not in contact with each other and a conductive position where the terminal and the contact are in contact; The slider is supported at the other end and engaged with the heart cam groove formed on the bottom surface of the storage portion, and the engagement position with the heart cam groove is changed to thereby hold the slider at the conduction position and release the holding. a cam bar to perform a metallic cover member for closing the ceiling surface of the housing, a single cantilever spring molded cut and raised to the cover member, the free Section is, the slider constitutes a first pressing portion that presses the other end portion or the vicinity of the other end of the cam bar to the bottom side when located in the non-conducting position, the intermediate portion in the longitudinal direction, the projecting the bottom side of the straight line connecting the free end support end in a free state of the cantilever spring, the slider is the other end or the other end portion near the first pressing portion when located in the introducing position And an urging means that constitutes a second pressing portion that presses toward the bottom surface side with a larger urging force.

  The memory card connector of the present invention can be mounted on, for example, a portable terminal.

According to the present invention, when applied to the connector ( Claim 1 or 2 ) and when applied to the portable terminal ( Claim 3 ), the first pressing portion of the urging means is applied when the slider is located at the non-conductive position. The other end of the cam bar facing the heart cam groove or the vicinity of the other end is pressed against the bottom surface of the housing, and when the slider is in the conducting position, the second pressing portion of the urging means is The other end or the vicinity of the other end is pressed toward the bottom surface of the housing. Therefore, it is possible to reliably prevent the other end portion of the cam bar from being lifted from the heart cam groove and falling off regardless of the position of the slider.
Further, since the urging means generates a stronger urging force (pressing force) in the second pressing portion than when the first pressing portion comes into contact with the cam bar, the slider is in the initial operation (from the non-conductive position to the conductive position side). (Sliding motion to the rear), it is possible to effectively prevent the heart cam groove from being shaved and the bottom surface of the housing from being warped, and to perform a smooth operation. Further, when the slider is positioned at the conducting position, the slider can be reliably held at the conducting position by the heart cam groove and the cam bar. Further, when the slider moves in the vicinity of the conduction position and the other end of the cam bar climbs over the step of the heart cam groove, a clear click feeling can be given to the operator.
Furthermore, since the distance from the support end of the cantilever spring to the first pressing portion (free end) is longer than the distance from the support end to the second pressing portion (intermediate portion), the second pressing portion contacts the cam bar. When contacting, the urging means generates a stronger urging force (pressing force) than when the first pressing portion contacts the cam bar. Therefore, an urging means having a simple structure in which the second pressing portion generates a stronger urging force than the first pressing portion can be obtained.
Furthermore, since the second pressing portion protrudes from the straight line connecting the support end and the free end of the cantilever spring to the bottom side, the portion other than the portion where the cam bar and the leaf spring abut regardless of the non-conductive position or the conductive position. However, since they are close to each other, even if the cam bar is subjected to vibration or shock due to disturbance and an unnecessary inclination occurs (even if it behaves irregularly), the cam bar can be stably pressed. Further, since the length of the cantilever spring can be increased, the spring property can be ensured even when the connector is made lighter and thinner, and the cam bar can be stably pressed.
In addition, since the single cantilever spring is integrally formed with the metal cover member, the relative position of the cantilever spring with respect to the connector is stabilized, and excellent spring properties are obtained while being a small and low-profile connector. be able to. In addition, it is possible to reduce the number of parts and manufacturing costs such as assembly.

  According to the sixth aspect of the present invention, it is possible to provide a portable terminal that is excellent in operation feeling and workability / stability when a memory card is inserted / removed, and that holds the memory card reliably.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Note that the front-rear and left-right directions in the following description are based on the directions of the arrows shown in FIG.
As shown in FIG. 2 and the like, the connector 10 of this embodiment is a connector for a microSD card MC and can be mounted on, for example, a mobile phone, a PDA, a personal computer, a digital camera, a digital video camera, a portable music terminal, or the like.
The connector 10 includes a housing 15, a slider 40, a cam bar 60, a cover member 70, a compression coil spring S1, and a compression coil spring S2 as large components.
The housing 15 having a substantially rectangular shape in plan view is an integrally molded product made of an insulating synthetic resin material, and a portion surrounded by the rear wall 16, the left side wall 17, and the right side wall 18 is a storage unit 19 whose front and upper surfaces are open. It has become. The housing 15 is integrally provided with a total of eight contacts 20 arranged in the left-right direction. The front half part of each contact 20 is located in the storage part 19, and the front end part of each contact 20 is a contact end part 20a. Further, the rear end portion of each contact 20 penetrates the rear wall 16 rearward, and the tail portion 21 forming the rear end portion of each contact 20 is soldered to the circuit pattern of the substrate not shown behind the rear wall 16. It is attached. Further, three engaging projections 22 project from the outer surfaces of the left side wall 17 and the right side wall 18.
In the vicinity of the right corner on the rear side of the bottom surface of the housing 15, a rear partition wall 24 is formed so as to be parallel to the right side wall 18 and whose rear end is connected to the rear wall 16. Further, a front end wall 25 connected to the front end of the right side wall 18 protrudes from the right end of the front edge of the housing 15, and the right side wall 18, the front end wall 25, the rear partition wall 24, and the rear wall 16. A portion surrounded by the right end portion of this is a spring accommodating space 26. A spring support shaft 27 and a spring support shaft 28 that are coaxial with each other protrude from the front surface of the right end portion of the rear wall 16 and the rear surface of the front end wall 25.
A slider guide groove 29 that is located on the left side of the spring accommodating space 26 and extends in the front-rear direction is recessed in the bottom surface of the housing 15. Further, a heart cam groove 30 is recessed in a portion located immediately after the slider guide groove 29 on the bottom surface portion of the housing 15. As shown in detail in FIGS. 8 and 9, the heart cam groove 30 is a groove having a number of steps recessed around the heart-shaped convex portion 31, and includes an initial engagement portion 32 that forms the front end portion thereof, A push-in passage portion 33 located on the right side of the convex portion 31, a holding portion 34 located at the rear end portion of the heart-shaped convex portion 31, and a return passage portion 35 located on the left side of the heart-shaped convex portion 31. is doing.
The mounting groove 37 that is recessed in the front-rear direction intermediate portion of the left side wall 17 has a pressed portion 38 that protrudes toward the right side in the vicinity of the rear end portion, and further has a protrusion 39a at the rear end portion of the outer surface. The second switch terminal 39 is fitted and fixed. Furthermore, a first switch terminal (detection means) 36 is integrally provided on the left side wall 17 in a manner located outside the second switch terminal (detection means) 39. Both the tail portion (not shown) of the first switch terminal 36 and the tail portion 39b of the second switch terminal 39 are soldered to the detection circuit pattern on the substrate.

A guide projection 41 having the same width as the slider guide groove 29 and a shorter front-rear length than the slider guide groove 29 is provided on the lower surface of the slider 40, which is a molded product made of a synthetic resin material. Since the guide protrusion 41 is slidably fitted in the slider guide groove 29, the slider 40 can slide on the bottom surface of the connector 10 along the slider guide groove 29. A memory card engagement portion 42 is provided at the left end portion of the slider 40, and the left side surface of the front end portion of the memory card engagement portion 42 is inclined at an angle of approximately 45 ° with respect to the front-rear direction and the left-right direction. An inclined surface 43 is formed.
On the other hand, a spring support portion 44 located in the spring accommodating space 26 is provided at the right end portion of the slider 40, and the front and rear surfaces of the spring support portion 44 are coaxial with each other, and the spring support shaft 27 and the spring support shaft 28. A spring support shaft 45 and a spring support shaft 46 that are coaxial with each other are projected. The front and rear end portions of the compression coil spring S1 are fitted to the spring support shaft 45 and the spring support shaft 27, respectively, and the front and rear end portions of the compression coil spring S2 are fitted to the spring support shaft 28 and the spring support shaft 46, respectively. . Since the urging force of the compression coil spring S1 is larger than the urging force of the compression coil spring S2, the compression coil spring S1 and the compression coil spring S2 are in a state where no external force other than the compression coil spring S1 and the compression coil spring S2 is applied to the slider 40. Due to the forward biasing force (hereinafter referred to as “forward biasing force due to the compression coil spring S1”) due to the difference in strength between the slider 40 and the slider 40, the front end of the guide protrusion 41 contacts the front end surface of the slider guide groove 29. It is located at the conducting position (position shown in FIGS. 4 and 5).
A mounting groove 47 having a substantially L-shape in plan view is formed on the upper surface of the slider 40, and a projection 48 is provided on the front end of the slider 40. The mounting groove 47 is fitted with a rear end portion 52 having a substantially L shape of a lock fitting 50 having an elastic engagement portion 51 at the front end, and the right side surface of the front end portion of the lock fitting 50 is formed on the protrusion 48. Elastic contact. Further, a support recessed portion 49 is formed on the upper surface of the rear end portion of the slider 40.

The cam bar 60 is a member that links the heart cam groove 30 formed on the bottom surface of the housing 15 and the slider 40. That is, the cam bar 60 has a front end engagement protrusion (one end) 61 and a rear end engagement protrusion (other end) 62 that are bent downward at both front and rear ends thereof. The rear end engaging projection 62 is engaged with the heart-shaped convex portion 31 so as to be relatively movable.
Thus, the ceiling surface of the housing 15 that houses the slider 40, the compression coil spring S1, the compression coil spring S2, and the cam bar 60 is covered with the cover member 70 that is a press-formed product of a metal plate. A plurality of engagement holes 71 are formed in the side wall of the cover member 70, and a downward fitting protrusion 72 is provided at the front end of the cover member 70. Then, by engaging the corresponding engaging protrusion 22 of the housing 15 in each engaging hole 71 and fitting the fitting protrusion 72 into the fitting recess 23 provided in the front end wall 25 of the housing 15. The cover member 70 is prevented from falling off from the housing 15. In addition, two tail portions 73 project from the lower end portions of the left and right side walls of the cover member 70, and these tail portions 73 are soldered to the ground pattern of the substrate.
As shown in FIGS. 1, 2, 10, and 11, in the vicinity of the right corner of the rear end of the upper surface of the cover member 70, a cantilever plate that is simultaneously formed when the cover member 70 is formed by the above press molding. A spring 74 is provided. In the intermediate portion of the leaf spring 74, an intermediate bent portion (second pressing portion) 76 is formed which is located on the bottom surface side of the housing 15 with respect to a straight line connecting the free end portion (first pressing portion) 75 and the supporting end portion in the free state. It is. The leaf spring 74 is a biasing means that always presses the cam bar 60 toward the bottom surface side (downward) of the housing 15.

Next, an operation when the microSD card MC is inserted into and removed from the connector 10 having the above configuration will be described.
As shown in FIG. 1, when the microSD card MC is not inserted into the connector 10, the slider 40 is located at the non-conducting position as shown in FIG. Is engaged with the initial engagement portion 32 of the heart cam groove 30 (see FIGS. 4 and 5).
In this state, when the microSD card MC is inserted into the storage portion 19 from the front opening of the connector 10 and pushed backward, the engagement protrusion MC1 formed at the rear portion of the right edge of the microSD card MC becomes the elastic engagement of the lock fitting 50. Get over the joint 51 while elastically deforming it. Then, as shown in FIGS. 4 and 5, the contact inclined surface MC2 forming the front surface of the engaging projection MC1 contacts the inclined surface 43 of the slider 40, and the elastic engaging portion 51 of the lock fitting 50 is connected to the microSD card MC. Therefore, the microSD card MC is integrated with the slider 40.
As shown in FIG. 10, when the slider 40 is located at the non-conduction position, the free end portion 75 of the leaf spring 74 presses the vicinity of the rear end portion of the cam bar 60 downward. As compared with the case where the front end portion 60 (or the vicinity of the front end portion) is pressed downward, the rear end engaging protrusion 62 can be reliably prevented from being lifted from the initial engaging portion 32 (the rear end engaging protrusion 62 and the initial position). The engaging portion 32 can be reliably engaged).
On the other hand, the distance from the support end portion of the leaf spring 74 to the free end portion 75 is relatively long (since it is longer than the distance from the support end portion to the intermediate bent portion 76). The urging force exerted on is not so great. Therefore, the slider 40 and the microSD card MC can be smoothly slid rearward against the forward biasing force of the compression coil spring S1 without pushing the microSD card MC backward with such a large force. Further, since the frictional resistance force generated between the rear end engaging protrusion 62 and the initial engaging portion 32 at this time is small, it is possible to effectively prevent the initial engaging portion 32 from being worn and the bottom surface portion of the housing from warping. it can.

The microSD card MC and the slider 40 slide rearward together, and the rear end engaging projection 62 of the cam bar 60 passes through the passage portion 33 when pushed in and is positioned behind the heart-shaped convex portion 31 and then rearward with respect to the microSD card MC. When the pressing force is released, the slider 40 and the microSD card MC are pushed back forward by the forward biasing force of the compression coil spring S1, and the rear end engaging projection 62 is engaged with the holding portion 34, so that the slider 40 is shown in FIG. 6 and the conductive position shown in FIG. When the slider 40 is located at the conduction position, each terminal (not shown) formed on the lower surface of the microSD card MC comes into contact with the corresponding contact end portion 20a of the contact 20 and is electrically conducted. Furthermore, since the left side surface of the front end portion of the microSD card MC presses the pressed portion 38 of the second switch terminal 39 to the left side, the protrusion 39a contacts the front end portion of the right side surface of the first switch terminal 36. Then, since a detection signal is sent to the control unit of the electronic device (mobile phone, personal computer, digital camera, etc.) on which the connector 10 is mounted through the detection circuit pattern formed on the substrate, the control unit makes contact with the microSD card MC. It is detected that 20 is electrically conductive.
As shown in FIG. 11, when the slider 40 is positioned at or near the conducting position, the intermediate bent portion 76 of the leaf spring 74 presses the vicinity of the rear end portion of the cam bar 60 downward, so that the front end portion or front end portion of the cam bar 60 As compared with the case where the vicinity is pressed, it is possible to reliably prevent the rear end engaging protrusion 62 from being lifted from the initial engaging portion 32.
Further, since the distance from the support end portion of the leaf spring 74 to the intermediate bent portion 76 is shorter than the distance from the support end portion to the free end portion 75, the urging force exerted by the intermediate bend portion 76 on the cam bar 60 at this time is determined by the slider 40. The free end portion 75 is larger than the urging force exerted on the cam bar 60 when positioned at the non-conduction position. Therefore, when the rear end engaging projection 62 gets over the step between the passing portion 33 and the holding portion 34 when pushed in, or the step between the holding portion 34 and the passing portion 35 when returning, a clear click feeling can be given to the operator. . In addition, since the rear end engaging projection 62 and the holding portion 34 are reliably engaged with each other with a strong force, the slider 40 is reliably held at the conducting position by the rear end engaging projection 62 and the holding portion 34. .

With the slider 40 held in the conducting position by the rear end engaging protrusion 62 and the holding portion 34 of the cam bar 60, the slider 40 is pushed back further against the forward biasing force of the compression coil spring S1, and further microSD When the rearward pressing force on the card MC is released, the rear end engaging projection 62 moves away from the holding portion 34 to the return passage portion 35 side by the forward biasing force of the compression coil spring S1, and the return passage portion. It moves automatically through 35 to the front end of the initial engaging portion 32. Accordingly, the slider 40 returns to the non-conducting position, and the contact between the terminals of the microSD card MC and each contact 20 is released. Further, the left side surface of the front end portion of the microSD card MC is separated from the pressed portion 38 of the second switch terminal 39, and the protrusion 39a of the second switch terminal 39 is separated from the front end portion of the right side surface of the first switch terminal 36. The control unit of the electronic device detects that the card MC and the contact 20 are in a non-conductive state.
After the slider 40 returns to the non-conducting position in this way, the microSD card MC is pulled forward from the connector 10 by pulling the microSD card MC forward until the engagement protrusion MC1 gets over the elastic engagement portion 51 of the lock fitting 50. It can be taken out.

As described above, in the present embodiment, a pressing force is applied from the leaf spring 74 to the vicinity of the rear end portion of the cam bar 60 when the slider 40 is located at either the non-conductive position or the conductive position. The lifting of the engaging protrusion 62 from the heart-shaped convex portion 31 can be reliably prevented.
Moreover, when the slider 40 is located at the non-conducting position, a relatively weak pressing force is exerted on the cam bar 60 from the free end portion 75, and when the slider 40 is located at the conducting position, a strong pressing force is exerted on the cam bar 60 from the intermediate bent portion 76. Therefore, it is possible to apply a pressing force having an optimum strength from the leaf spring 74 to the cam bar 60 according to the position of the slider 40.

The present invention is not limited to this embodiment, and can be implemented with various modifications.
For example, the pressing force exerted on the cam bar 60 from the leaf spring 74 can be adjusted by changing the overall length, the plate thickness, the width, the material, the position of the intermediate bent portion 76, and the like of the leaf spring 74.
Further, the leaf spring 74 may not be formed integrally with the cover member 70 but may be a separate member.
Further, the plate spring 74 may be a resin spring. In this case, for example, the cover member 70 may be made of resin, and the leaf spring 74 may be integrally provided by cutting and raising the cover member 70.

Further, in the present embodiment, the vicinity of the rear end portion of the cam bar 60 is pressed by the free end portion 75 and the intermediate bent portion 76 of the leaf spring 74, but the rear end portion of the cam bar 60 is pressed by the free end portion 75 and the intermediate bent portion 76. You may make it press (the part right above the rear-end engagement protrusion 62).
Further, the leaf spring 74 has a circular arc shape in a side view that curves downward (the central portion is located at the lowest position, and the entire intermediate portion excluding the front and rear ends of the arc-shaped portion constitutes an intermediate protrusion), and slider The rear end portion (or the vicinity of the rear end portion) of the cam bar 60 while the leaf spring 74 changes its position from the vicinity of the front end portion (first pressing portion) to the vicinity of the rear end portion (second pressing portion) according to the position 40. You may make it press.
Furthermore, intermediate bent portions positioned on the bottom surface side of the housing 15 from a straight line connecting the free end portion 75 and the support end portion in a free state may be formed at a plurality of locations in the intermediate portion of the leaf spring 74. FIG. 12 shows an example in which two intermediate bent portions 77 and 78 are formed at two locations in the intermediate portion of the leaf spring 74. In this modification, when the slider 40 is located at the non-conduction position (in FIG. 12), the free end portion 75 presses the vicinity of the rear end portion (or the rear end portion) of the cam bar 60 and the slider 40 is in the non-conduction position. The intermediate bent portion 77 presses the vicinity (or the rear end portion) of the cam bar 60 when it is positioned between the conductive position and the intermediate bent portion 78 of the cam bar 60 when the slider 40 is positioned at the conductive position. The vicinity of the rear end (or the rear end) is pressed.
In addition, the connector 10 of the present embodiment is for the microSD card MC, but may be implemented as a connector for other memory cards (SD card, miniSD card, microSD card, memory stick, xD picture card, MMC, etc.). Of course it is possible.
