Description

  The present invention relates to a card connector.

  Conventionally, in electronic devices such as personal computers, mobile phones, PDAs (Personal Digital Assistants), digital cameras, video cameras, music players, game consoles, and vehicle navigation devices, SIM (Subscriber Identity Module). Card, MMC (Multi Media Card) (R), SD (Secure Digital) (R) card, miniSD (R) card, xD picture card (xD-Picture card) (R), Memory Stick (R), SmartMedia ( In order to use various memory cards such as R), a card connector is provided.

  In recent years, a card connector has a push / push structure in which a memory card is operated to be pushed in even when the memory card is inserted or removed from the viewpoint of usability. However, in the card connector having the push / push structure, the card is slid by the repulsive force of the spring when the card is ejected, so the moving speed of the card and the slide member for holding the card is increased, and the card is ejected. The slide member may collide with the stopper member and an impact may be generated. In view of this, a technique has been proposed in which a speed reduction device is used to reduce the moving speed of the card and the slide member when the card is ejected (see, for example, Patent Document 1).

  FIG. 10 is an exploded view showing a conventional card connector.

  In the figure, reference numeral 811 denotes a card connector housing made of an insulating material such as synthetic resin, and includes a plurality of connection terminals 851 made of metal. Reference numeral 861 denotes a card connector shell made of a metal plate and attached to the upper side of the housing 811. A memory card 901 is inserted into the space between the shell 861 and the housing 811, and a contact pad (not shown) of the memory card 901 comes into contact with the corresponding connection terminal 851.

  In the example shown in the figure, the card connector is a so-called push / push type connector, and has a guide mechanism for discharging the memory card 901. The guide mechanism includes a slide member 821 that engages with the memory card 901 and slides together with the memory card 901, and a coil spring 881 that biases the slide member 821 in the direction of ejecting the memory card 901.

  A guide mechanism housing groove 811h is formed on one side of the housing 811. The slide member 821 is slidably housed inside the guide mechanism housing groove 811h. Further, a cam groove 823 of a heart cam mechanism is formed on the upper surface of the slide member 821, and one end of a pin member 871 of the heart cam mechanism is engaged with the cam groove 823. The other end of the pin member 871 is locked in the vicinity of the stopper portion 811g of the guide mechanism accommodation groove portion 811h. The pin member 871 is held by being biased downward from above by a leaf spring 865 of the shell 861.

  Further, the slide member 821 includes a first engaging portion 821c that engages with the front end of the memory card 901, a protruding portion 824 that engages with the front end of the engaging convex portion 911 of the memory card 901, and an engaging concave portion of the memory card 901. The second engagement portion 821d that engages with the 912 and the contact portion 821e that contacts the stopper portion 811g and stops the slide member 821 are provided.

  When the memory card 901 is inserted into the housing 811 and pushed by the user's finger, the memory card 901 is pushed in the back direction of the housing 811 (upper right direction in the figure). Then, the front end of the memory card 901, the engaging convex portion 911 and the engaging concave portion 912 are engaged with the first engaging portion 821c, the protruding portion 824, and the second engaging portion 821d of the slide member 821, and the slide member 821 is Then, it moves to the back of the housing 811 together with the memory card 901 against the repulsive force of the coil spring 881. Then, when one end of the pin member 871 is hooked on the cam groove 823 by the action of the heart cam and the slide member 821 stops, the memory card 901 is also stopped while being inserted into the housing 811.

  Next, when the memory card 901 is pushed out by the user's finger when the memory card 901 is taken out from the housing 811, the state where one end of the pin member 871 is hooked in the cam groove 823 is released. As a result, the slide member 821 is opened and moved together with the memory card 901 by the force exerted by the coil spring 881 (to the left in the figure), so that the memory card 901 is ejected from the housing 811.

  Further, a cantilever-like braking shoe 819 having springiness is formed on the side wall of the guide mechanism housing groove 811h. Furthermore, push-up springs 852R and 852L are disposed on both sides of the plurality of connection terminals 851. The surface of the brake shoe 819 is pressed against the side surface of the projecting portion 824 of the slide member 821, and the upper surfaces of the lifting springs 852R and 852L are pressed against the lower surface of the memory card 901.

  Thus, when the memory card 901 is ejected from the housing 811, the moving speed of the slide member 821 and the memory card 901 is decelerated by the brake shoe 819 and the push-up springs 852R and 852L. It does not occur or the contact part 821e of the slide member 821 collides with the stopper part 811g and an impact does not occur.

  However, in the conventional card connector, since the push-up springs 852R and 852L need to be separately attached, the number of parts increases and the cost also increases. In recent years, with the rapid price reduction, the outer shape finishing accuracy of the memory card 901 is lowered, and the dimensional accuracy of the surface of the memory card 901 is lowered. That is, even in the same type of memory card 901, the thickness dimension varies, and the surface roughness or smoothness also varies. Therefore, when the memory card 901 has a large thickness, the pressing force of the push-up springs 852R and 852L increases, and the braking force becomes larger than expected, so that the ejection of the memory card 901 is hindered. . On the contrary, when the memory card 901 has a small thickness, the pressing force of the push-up springs 852R and 852L becomes small and the braking force becomes smaller than expected, so the memory card 901 pops out. . Similarly, when the surface of the memory card 901 is rough, the braking force becomes larger than expected and the ejection of the memory card 901 is hindered, and when the surface of the memory card 901 is smooth, the braking force becomes smaller than expected. The memory card 901 pops out.

  Further, the brake shoe 819 has a spring property and needs to be formed in a cantilever shape on the side wall of the guide mechanism accommodation groove 811h. On the other hand, in recent years, with the rapid miniaturization of electronic devices, the memory card 901 and the card connector tend to be miniaturized rapidly. For this reason, the side wall of the guide mechanism accommodation groove 811h of the housing 811 manufactured by integrally molding an insulating material such as synthetic resin stably exhibits springiness and has a cantilever-like extremely complicated shape. It is extremely difficult to form the brake shoe 819 having a very small size, and if possible, the cost becomes high.

  The present invention solves the problems of the conventional card connector, and forms a plurality of convex portions on the surface of the slide member that holds and slides the card, and a cantilever-like leaf spring member formed on the shell. Regardless of the accuracy of the card, it is possible to stably exert a braking force of an appropriate magnitude at an appropriate timing by braking the slide member by intermittently abutting against a plurality of convex portions. , The card can be reliably and stably discharged at an appropriate speed, the card will not be ejected, the structure is simple, the number of parts is not increased, and the production is easy. An object is to provide a card connector with low cost and high reliability.

For this purpose, in the card connector of the present invention, a housing for housing a card having a terminal member, a connection terminal attached to the housing and contacting the terminal member of the card, and a card inserted in the housing are held. And a urging member that urges the sliding member in a direction opposite to the insertion direction of the card, and holds the card in the locked position so that the terminal member of the card contacts the connection terminal. And when the card moves in the insertion direction by the push operation of pushing the card held in the lock position in the insertion direction and reaches the overstroke position, the biasing force of the biasing member A card guide mechanism for discharging the card by moving the card from the overstroke position in the direction opposite to the insertion direction, and the housing A card connector having at least a slide member and a cover member that covers a part of the card inserted in the housing, the cover member having a base end integrally connected to the cover member, A cantilever-like braking member having a sliding portion formed at a free end is provided, and the slide member includes a braked portion including a braking surface with which the sliding portion can come into contact. A plurality of convex portions arranged side by side in the card insertion direction are formed, and when the card is in the overstroke position, the sliding portion is inserted in the card insertion direction with respect to the convex portion located on the most front side in the braking surface. in contact with the front part of, when said card is in the locked position, you abut the surface of the convex portion positioned on the nearest side.

  In another card connector of the present invention, the braking surface also includes the surface of the convex portion, and changes from the front side to the back side in the card insertion direction in the order of low, high and low.

  In still another card connector according to the present invention, the braking force for braking the slide member generated by the sliding portion coming into contact with the braking surface is such that the slide member inserts a card from an overstroke position. When moving in the direction opposite to the direction, the direction changes from low to high to low.

  In still another card connector of the present invention, the braking member exerts a spring force, and the sliding portion is pressed against the braking surface by the spring force.

  In yet another card connector according to the present invention, the slide member abuts against a stopper portion provided in the housing when the card is ejected, and the slide member is stopped by the slide member. When stopped by coming into contact with the stopper portion, it comes into contact with the innermost portion in the card insertion direction with respect to the convex portion located on the innermost side in the braking surface, or the card insertion direction with respect to the braked portion. It is located in the back side of and does not contact the braking surface.

  In still another card connector of the present invention, when the card is in a position where the connection between the terminal member and the connection terminal is released when the card is ejected, the braking is performed. Between the convex portion located on the front side and the convex portion located on the deepest side on the surface, the surface abuts on a portion having no convex portion.

  In still another card connector of the present invention, the sliding portion further includes a position where the connection between the terminal member and the connection terminal is released when the card is ejected, and the slide member. When it is between a position where it comes into contact with the stopper provided in the housing and stops, it comes into contact with the surface of the convex portion located on the innermost side of the braking surface.

  In still another card connector of the present invention, the biasing member is a coil spring, and exerts a biasing force in a compressed state.

  According to the present invention, the card connector forms a plurality of convex portions on the surface of the slide member that holds and slides the card, and the cantilever-shaped leaf spring member formed on the shell is intermittently formed on the plurality of convex portions. It is made to contact | abut. As a result, regardless of the accuracy of the card, a braking force of an appropriate magnitude can be stably exhibited at an appropriate timing, and the card can be reliably and stably discharged at an appropriate speed. The card does not fly out, the structure can be simplified, the increase in the number of parts can be prevented, the manufacturing can be facilitated, the cost can be reduced, and the reliability can be improved.

A card 101 to be described later is inserted into the card connector 1, and the card 101 is attached to the electronic device via the card connector 1. The electronic device is, for example, a personal computer, a mobile phone, a PDA, a digital camera, a video camera, a music player, a game machine, a vehicle navigation device, or the like, but may be any type of device.

  The card 101 is, for example, a SIM card, MMC (R), SD (R) card, miniSD (R) card, xD picture card (R), memory stick (R), memory stick Duo (R), smart It is an IC card such as a media (R), T-Flash (Trans-Flash) memory card, micro SD (R) card, etc., and any type of card may be used, but in this embodiment, micro SD ( R) It is assumed that it is a card.

  In the present embodiment, the expressions indicating directions such as upper, lower, left, right, front, rear, etc. used for explaining the configuration and operation of each part of the card connector 1 are absolute. It is appropriate when the card connector 1 or its parts are in the posture shown in the figure, but when the card connector 1 or its parts change, the posture changes. It should be interpreted accordingly.

  Here, the card connector 1 is integrally formed by punching and bending a housing 11 integrally formed of an insulating material such as synthetic resin and a plate material made of a conductive material such as metal. And a shell 61 as a cover member that is molded and attached to the upper side of the housing 11. The shell 61 covers the upper part of the housing 11 and at least a part of the card 101 accommodated in the housing 11. The card connector 1 has a generally flat rectangular parallelepiped shape, is attached to the electronic device, and the card 101 is inserted from the front (upper left in the figure).

  FIG. 3 is a perspective view of the housing 11 with the shell 61 removed for explanation.

  As shown in the figure, the housing 11 has a bottom wall portion 11b having a shape in which the front edge side (the upper left side in the figure) which is the front side in the insertion direction of the card 101 is cut into a substantially U shape or a substantially U shape. And a back wall portion 11a that extends along the edge of the back side (lower right side in the drawing) in the back portion of the bottom wall portion 11b and stands from the bottom wall portion 11b. Here, the bottom wall portion 11b includes a terminal holding portion 11e to which a terminal 51 as a connection terminal is attached on the upper surface. A plurality of terminal loading grooves formed so as to extend in the front-rear direction (the direction connecting the upper left and the lower right in the figure) are formed on the upper surface of the terminal holding portion 11e, and are connected to each terminal loading groove. A terminal 51 as a terminal is inserted and attached.

  The base 51a of the terminal 51 is mounted in the terminal loading groove, and the tip 51b extends obliquely upward toward the back wall 11a and protrudes upward from the upper surface of the bottom wall 11b. Yes. The front end portion 51 b of the terminal 51 functions as a contact portion, and is in contact with and electrically connected to a contact pad 151 as a terminal member disposed on the lower surface of the card 101. A solder tail portion 51c extending from the base portion of the terminal 51 protrudes forward from the front edge of the bottom wall portion 11b, and is formed on a signal board or contact pad formed on a wiring board or the like in the electronic device. The terminals are electrically connected to the mating terminal member by soldering or the like.

  Further, an opening portion 11i penetrating the bottom wall portion 11b in the thickness direction is formed in a portion of the bottom wall portion 11b corresponding to the lower portion of the tip portion 51b of the terminal 51. The opening 11i can be omitted as necessary.

  The housing 11 is formed on the first side wall portion 11c as an L-shaped side wall extending in the front-rear direction along one side edge of the bottom wall portion 11b, and on the other side edge of the bottom wall portion 11b. It has the 2nd side wall part 11d as a side wall extended in the front-back direction along.

  A card guide mechanism accommodating portion 11h is formed inside the second side wall portion 11d, and a card guide mechanism slide member for guiding the card 101 inserted into the card connector 1 into the card guide mechanism accommodating portion 11h. 21 is slidably attached in the front-rear direction. Here, the slide member 21 includes a card holding portion 21a for holding the card 101, a slide cam portion 21b as a moving cam member, and a braked portion 21g that receives a braking force for controlling the slide speed. Have. The card holding part 21a, the slide cam part 21b, and the braked part 21g are integrally formed of an insulating material such as synthetic resin.

  And the said card | curd holding | maintenance part 21a is provided with the 1st engaging part 21c and the 2nd engaging part 21d which were formed so that it might protrude from the inner side surface. The first engaging portion 21 c and the second engaging portion 21 d engage with an engaging portion including irregularities formed on the side surface of the card 101. The slide member 21 holds the card 101 by the first engaging portion 21c and the second engaging portion 21d of the card holding portion 21a and moves in the front-rear direction together with the card 101.

  Further, the back side surface of the card holding portion 21a functions as a biasing force receiving portion 21e that receives a biasing force of a biasing member 81 as a coil spring that exerts a biasing force in a compressed state. The urging force receiving portion 21e is formed with a locking projection 21f for locking the urging member 81, and one end of the urging member 81 is attached. The other end of the urging member 81 is attached to the back wall portion 11a. The back wall portion 11a also includes a locking projection for locking the biasing member 81. As a result, the slide member 21 is urged by the urging member 81 in the direction opposite to the insertion direction of the card 101, that is, the ejection direction of the card 101.

  The card connector 1 requires an operation of pushing the card 101 both when the card 101 is inserted into the card connector 1 and when the card 101 is taken out from the card connector 1. , A push-in push-out type, or a push / push type. Such an operation is similar to the alternate operation (position holding type, push-on / push-off type) in the field of push button switches. The slide cam portion 21b functions as a slide cam in a heart-shaped cam mechanism for performing a push / push type operation.

  Therefore, a cam groove 23 is formed on the upper surface of the slide cam portion 21b, and a free end of an elongated pin member 71 as a fixed cam member is engaged with the cam groove 23. Further, the other end of the pin member 71 is hooked on the upper surface of the hooking portion 11f formed in the portion near the back wall portion 11a in the card guide mechanism housing portion 11h of the housing 11 as a fixed end. Has been. The pin member 71 and the cam groove 23 cooperate to cause the slide member 21 that moves together with the card 101 to perform a push / push type operation. As a result, when the card 101 moves in the insertion direction and reaches the end point by a push operation for pushing the card 101 in the insertion direction, the card guide mechanism terminates the card 101 by the biasing force of the biasing member 81. It can be discharged from the point in the direction opposite to the insertion direction. The slide member 21 moving in the direction opposite to the insertion direction comes into contact with and stops at the stopper portion 11g formed near the front side end of the second side wall portion 11d.

  The pin member 71 is held by being urged downward from above by a pin pressing member 65 of the shell 61. The pin pressing member 65 is a plate-like member having a spring property formed by bending a part of the shell 61 so as to be pressed in the direction of the bottom wall portion 11 b of the housing 11. It is positioned between the pin pressing member 65 and the slide member 21 or the housing 11 and is held so as not to be detached from the slide member 21 or the housing 11.

  In addition, the shell 61 includes a substantially rectangular top plate portion 62 and a plurality of side plate portions 64 erected from a plurality of locations on the side edge of the top plate portion 62. A plurality of latching openings 63 are formed in the side plate portion 64, and as shown in FIG. 2, when the shell 61 is attached to the upper side of the housing 11, the rear wall portion 11a and the first side wall portion 11c of the housing 11 are provided. And the said latching opening 63 is latched by the latching protrusion 13 formed in the outer surface of the 2nd side wall part 11d, and, thereby, the shell 61 is fixed to the housing 11. FIG.

  Further, the shell 61 has a braking member 66 formed on the top plate portion 62 in addition to the pin pressing member 65. The braking member 66 is a cantilever-shaped leaf spring member formed by cutting and raising a part of the top plate portion 62, and its base end portion is integrally connected to the top plate portion 62, and its free end portion has a free end portion. A convex sliding portion 66a protruding downward is formed. The braking member 66 is formed in the vicinity of the side plate portion 64 corresponding to the second side wall portion 11d of the top plate portion 62, extends as a whole along the side plate portion 64, and the sliding portion 66a is It extends from the base end portion to the back side and obliquely downward, that is, in a direction approaching the bottom wall portion 11b.

  On the other hand, the braked portion 21g of the slide member 21 is an elongated rectangular plate-like member that is disposed on the side of the slide cam portion 21b and extends in the moving direction of the slide member 21, that is, the front-rear direction. The lower surface of the braked portion 21 g slides on the slide surface 11 j that is the upper surface of the second side wall portion 11 d of the housing 11. That is, the braked portion 21g is supported and slid by the slide surface 11j from below.

  The upper surface of the braked portion 21g can contact the sliding portion 66a of the braking member 66, and receives a braking force when the sliding portion 66a contacts and slides. Functions as a braking surface. And on the surface of the said to-be-braking part 21g, the 1st convex part 21h1 located in the near side with respect to the insertion direction of the card | curd 101 and the 2nd convex part 21h2 located in the back | inner side with respect to the insertion direction of the card | curd 101 are formed. . Each of the first convex portion 21h1 and the second convex portion 21h2 has a rectangular side surface shape, and the surface thereof is parallel to the surface of the braked portion 21g, and similarly functions as a braking surface. The first convex portion 21h1 and the second convex portion 21h2 are formed in the longitudinal direction of the surface of the braked portion 21g, that is, in the middle range in the front-rear direction. The first convex portion 21h1 and the second convex portion 21h2 are separated from each other in the insertion direction of the card 101 by a predetermined interval. Therefore, the height of the braking surface of the braked portion 21g changes from the front side to the back side in the order of low, high and low. Note that the surfaces of the first convex portion 21h1 and the second convex portion 21h2 do not necessarily have to be flat. For example, a concave portion may be formed. Only explained.

  The braking member 66 is formed such that the sliding portion 66a corresponds to the surface of the braked portion 21g in a state where the shell 61 is fixed to the housing 11. Then, when the sliding portion 66a is pressed against the surface of the braked portion 21g by the spring force of the braking member 66, a braking force for braking the slide member 21 moving in the front-rear direction is generated. Since the braking member 66 is a member formed by subjecting the top plate portion 62 of the shell 61 made of a metal plate to processing such as punching and bending, it can be formed easily and with high accuracy, Since it is made of metal and has an extremely stable spring property, a braking force having a desired magnitude can be stably generated with the sliding portion 66a in contact with the surface of the braked portion 21g. However, the sliding portion 66a does not always need to abut the surface of the braked portion 21g to generate a braking force, and depending on the position of the slide member 21 that moves in the front-rear direction, the sliding portion 21g It may be in a state where it does not contact the surface and does not generate braking force.

  Further, a card detection switch for detecting that the contact pad 151 of the card 101 and the terminal 51 are in contact with each other at the back of the housing 11 and detecting that the card 101 is loaded in the card connector 1. Is arranged. The card detection switch is formed by the first contact member 52 and the second contact member 53 attached to the back wall portion 11a and the vicinity thereof. The switch may be any switch such as a switch for detecting the connection state between the contact pad 151 of the card 101 and the terminal 51. For convenience of explanation, only the case of the card detection switch will be described.

  The first contact member 52 has a mounting portion 52a attached to the back wall portion 11a, a base end connected to the mounting portion 52a, and a cantilever extending in the lateral direction, that is, toward the first side wall portion 11c. And a contact part 52c connected to the free end of the main body part 52b. The mounting portion 52a is substantially parallel to the side surface of the back wall portion 11a, and the main body portion 52b is inclined with respect to the side surface of the back wall portion 11a when the card 101 is not inserted into the card connector 1. The abutting portion 52c is disposed so as to protrude toward the near side in the insertion direction of the card 101. Therefore, when the card 101 is inserted, the front end of the card 101 comes into contact with the contact portion 52c.

  On the other hand, the second contact member 53 has an attachment portion 53a attached to a portion of the bottom wall portion 11b near the back wall portion 11a and a base end connected to the attachment portion 53a toward the first side wall portion 11c. It has a cantilever-shaped main body portion 53b that extends and a contact portion 53c that is connected to the free end of the main body portion 53b. The second contact member 53 is disposed below the first contact member 52 and close to the back wall portion 11a.

  Therefore, in a state where the card 101 is not inserted, the first contact member 52 and the second contact member 53 are not in contact with each other, and the card detection switch is in a non-conductive state, that is, off (OFF).

  However, when the card 101 is inserted and reaches the position where the contact pad 151 and the terminal 51 come into contact, the contact portion 52c of the first contact member 52 is pushed toward the back wall portion 11a by the front end of the card 101. As a result, the contact portion 52 c contacts the contact portion 53 c of the second contact member 53. As a result, the first contact member 52 and the second contact member 53 come into contact with each other, and the card detection switch is turned on, that is, turned on.

  Next, the card 101 will be described.

  4A and 4B are diagrams showing a card according to an embodiment of the present invention. FIG. 4A is a bottom view, and FIG. 4B is a top view.

  As described above, in the present embodiment, the card 101 is a micro SD® card, and has a substantially rectangular plate shape as shown in FIG. 4 is 15.0 [mm], and the width (left and right in FIG. 4) is 11.0 [mm]. A plurality of contact pads 151 are arranged along one edge at a position near the front end of the first surface.

  Next, the operation of the card connector 1 having the above configuration will be described. First, the operation when the card 101 is inserted will be described.

  First, the user inserts the card 101 from the front of the card connector 1 with fingers or the like. Note that the front end of the card 101 faces the inner wall 11a of the housing 11, the lower surface on which the contact pad 151 is disposed faces the bottom wall 11b, and the upper surface on which the contact pad 151 is not disposed is a shell. 61 is inserted in such a posture as to face the top plate 62 of 61. As a result, the card 101 has a side surface on which the convex concave portion flat portion as the engaging portion is formed along the second side wall portion 11 d of the housing 11, and the other side surface on the first side wall portion 11 c of the housing 11. Proceed along.

  Subsequently, when the user pushes the card 101 further into the card 101, the first engagement portion 21c and the second engagement portion 21d of the slide member 21 engage with the engagement portions on the side surface of the card 101, and the card 101 is securely held by the slide member 21 and moves toward the back wall portion 11 a together with the slide member 21. At this time, the pressing force exerted by the user's fingers and the like is transmitted from the engaging portion of the card 101 to the slide member 21 via the first engaging portion 21c and the second engaging portion 21d. Since the slide member 21 compresses the biasing member 81 formed of a coil spring, the slide member 21 and the card 101 receive the repulsive force of the biasing member 81, and the repulsive force is exerted by the user's fingers and the like. Since it is smaller than the pressing force to move, it moves against the repulsive force. In this case, the slide member 21 slides along the second side wall portion 11 d, and the card 101 advances together with the slide member 21. Then, the slide member 21 and the card 101 reach an overstroke position, which is a position advanced from the lock position, and enter an overstroke state.

  Subsequently, when the user stops pushing the card 101 and releases the pressing force on the card 101, the slide member 21 and the card 101 move in a direction away from the back wall portion 11 a by the repulsive force of the urging member 81. Be made. Then, the slide member 21 and the card 101 stop at the lock position where the card 101 is held in the card connector 1 while being locked. This is because the free end of the pin member 71 engaged with the cam groove 23 formed on the upper surface of the slide cam portion 21b of the slide member 21 is hooked on a part of the cam groove 23, and the movement of the slide member 21 is performed. This is because the slide member 21 is stopped at the lock position by stopping the movement.

  And the card | curd 101 will be in the state which can transmit / receive data between the calculating means etc. of an electronic device provided with the board | substrate with which the card | curd connector 1 was mounted by being hold | maintained in a locked position. When the card 101 is held in the locked position, the contact pad 151 of the card 101 is in contact with the tip 51b of the terminal 51 and is conductive. Further, the contact portion 52 c of the first contact member 52 of the card detection switch is pushed and displaced to the back side by the front end of the card 101 and is in contact with the contact portion 53 c of the second contact member 53. Thereby, the 1st contact member 52 and the 2nd contact member 53 contact, and the card detection switch is set to ON.

  Next, an operation for ejecting the card 101 from the card connector 1 will be described.

  FIG. 5 is a side view showing a state in which the side plate portion of the shell is removed when the slide member of the card connector in the embodiment of the present invention reaches the overstroke position, and FIG. 6 is a card in the embodiment of the present invention. The side view which shows the state which removed the side-plate part of the shell when the slide member of the connector for connectors reaches | attains a locked position, FIG. 7: the slide member of the card connector in embodiment of this invention reached the terminal discharge position FIG. 8 is a side view showing a state in which the side plate portion of the shell is removed, and FIG. 8 is a shell when the card connector slide member reaches between the terminal discharge position and the card temporary holding position in the embodiment of the present invention. FIG. 9 is a side view showing a state in which the side plate portion is removed, and FIG. 9 is a plan view when the slide member of the card connector in the embodiment of the present invention reaches the temporary card holding position. It is a side view showing a state in which Remove the side plate portion of the Le.

  First, when the user pushes and pushes the card 101 with fingers or the like, the slide member 21 and the card 101 are moved from the lock position toward the back wall portion 11a. When the user pushes the card 101 and pushes it further, the slide member 21 and the card reach the overstroke position, which is a position advanced from the lock position, as shown in FIG. It becomes.

  When the slide member 21 is in the overstroke position, the sliding portion 66a of the braking member 66 is in contact with the surface of the braked portion 21g. That is, it is in contact with a low part of the braking surface. Therefore, the slide member 21 receives a weak braking force at the overstroke position and in the vicinity thereof. However, when the slide member 21 is in the overstroke position and the sliding portion 66a is not in contact with the surface of the braked portion 21g, the slide member 21 exerts braking force in the overstroke position and in the vicinity thereof. You will not receive it.

  Subsequently, when the user stops pushing the card 101 and releases the pushing force against the card 101, the urging force of the urging member 81 causes the slide member 21 and the card 101 positioned at the overstroke position to It is moved in a direction away from the back wall 11a and moved in the direction opposite to the insertion direction. In this case, as described above, since the slide member 21 receives only a weak braking force from the braking member 66 or no braking force is generated, the urging force of the urging member 81 is caused by the braking force from the braking member 66. Almost never diminished.

  At the time when the slide member 21 and the card 101 start to move in the direction opposite to the insertion direction from the overstroke position, that is, at the first time of the process of discharging the card 101, the static friction is Since it is larger than the dynamic friction, it is necessary to apply a force large enough to overcome the static friction to the slide member 21 and the card 101 as a discharge force.

  For this reason, if the braking force from the braking member 66 is too strong at the beginning of the step of discharging the card 101, the urging force of the urging member 81 is greatly reduced, and a sufficiently large discharging force is generated by the slide member. 21 and the card 101 are not given, and the process of discharging the card 101 is not started. That is, the discharge property of the card 101 is lowered, and in the worst case, the card 101 is not discharged.

  However, in the present embodiment, since the slide member 21 receives only a weak braking force from the braking member 66 as described above at the beginning of the step of ejecting the card 101, the urging force of the urging member 81 Is not greatly reduced, and a sufficiently large discharging force is applied to the slide member 21 and the card 101. As a result, the surface of the card 101 is rubbed (rubbed) with the inner surface of the housing 11 and / or the shell 61, so that even if the friction received by the card 101 is large, the large amount applied to the slide member 21 and the card 101. Since the discharging force overcomes the friction, the card 101 is surely moved in the direction opposite to the insertion direction and discharged. That is, the discharge property of the card 101 is not lowered.

  When the process of discharging the card 101 is started, the slide member 21 and the card 101 move toward the near side by the urging force of the urging member 81, and pass through the lock position as shown in FIG. , Further moves in the direction opposite to the insertion direction of the card 101.

  When the slide member 21 is in the locked position and before and after that, the sliding portion 66a of the braking member 66 is in contact with the surface of the first convex portion 21h1. That is, it is in contact with a high part of the braking surface. Therefore, the slide member 21 receives a strong braking force in a predetermined range before and after the lock position, that is, in a range where the first convex portion 21h1 exists. Since the urging force of the urging member 81 is greatly reduced by the braking force from the braking member 66, the moving speed of the slide member 21 and the card 101 is effectively reduced. Thereby, it is possible to prevent the card 101 from jumping out of the card connector 1 vigorously.

  As described above, the first convex portion 21h1 and the second convex portion 21h2 are formed in an intermediate range in the front-rear direction of the surface of the braked portion 21g, and the height of the braking surface of the braked portion 21g is the near side. It changes from low to high and low to high from the side to the back side. And the position of the 1st convex part 21h1 located near this side is a little away from the sliding part 66a of the braking member 66 in the time of the slide member 21 being in an overstroke position, as FIG. 5 shows. Therefore, for a short period after the step of discharging the card 101 is started, the sliding portion 66a contacts the surface of the braked portion 21g and does not contact the surface of the first convex portion 21h1. That is, it abuts on a low part of the braking surface and does not abut on a high part. Therefore, the slide member 21 does not receive a strong braking force until the slide member 21 is accelerated by the urging force of the urging member 81 and reaches a certain speed. Then, as shown in FIG. 6, when the sliding portion 66a comes into contact with the surface of the first convex portion 21h1, the sliding member 21 and the card 101 have already moved, so that the received friction. Is changed to a dynamic friction smaller than the static friction, and inertia is generated, so that it does not stop even when a strong braking force is applied. That is, the discharge property of the card 101 is not lowered.

  By the way, when the part where the sliding part 66a abuts on the braking surface changes from the surface of the braked part 21g to the surface of the first convex part 21h1, that is, the sliding part 66a is on the front side of the first convex part 21h1. When contacting the end (the left end in FIGS. 5 and 6), the braking force increases stepwise, so the slide member 21 is considered to receive a very strong braking force. However, as described above, at this point of time, the friction is changed to a small dynamic friction, and in addition to the inertia being generated, the urging member 81 made of a coil spring is in a state of being greatly compressed. A large urging force is generated. Therefore, even if the slide member 21 receives a very strong braking force from the slide portion 66a, the slide member 21 and the card 101 do not stop. Furthermore, by appropriately changing the front side end of the first convex portion 21h1 and / or the shape of the sliding portion 66a, for example, by making the front side end of the first convex portion 21h1 into a curved surface or an inclined surface, Further, for example, by reducing the inclination of the outer shape of the sliding portion 66a or increasing the curvature, the braking force when the sliding portion 66a contacts the front side end of the first convex portion 21h1 is reduced. You can also.

  Then, after the slide member 21 and the card 101 pass through the lock position toward the near side by the biasing force of the biasing member 81, the slide member 21 and the card 101 further move and pass through the terminal discharge position as shown in FIG. Move in the direction opposite to the insertion direction. When the card 101 reaches the terminal discharge position, the contact between the contact pad 151 of the card 101 and the tip 51b of the terminal 51 which has been maintained until then is released, and the contact pad 151 and the terminal 51 become non-conductive. . Further, the contact portion 52c of the first contact member 52 of the card detection switch is returned to the original position by the spring property of the main body portion 52b. Therefore, since the first contact member 52 and the second contact member 53 are not in contact with each other, the card detection switch is turned off.

  When the slide member 21 is at the terminal discharge position and before and after the terminal discharge position, the sliding portion 66a of the braking member 66 contacts the surface of the braked portion 21g between the first convex portion 21h1 and the second convex portion 21h2. . That is, it is in contact with a low part of the braking surface. Therefore, the slide member 21 receives a weak braking force in a predetermined range before and after the terminal discharge position, that is, in a range between the first convex portion 21h1 and the second convex portion 21h2.

  As described above, the slide member 21 receives a strong braking force while the sliding portion 66a is in contact with the surface of the first convex portion 21h1 at and before and after the locked position. On the other hand, the contact pad 151 of the card 101 receives friction from the tip 51b because the tip 51b of the terminal 51 is in contact therewith. That is, the card 101 receives a relatively large dynamic friction, although the dynamic friction is smaller than the static friction. Furthermore, since the biasing member 81 made of a coil spring is slightly extended and the degree of compression is low, the generated biasing force is slightly reduced. Therefore, the difference between the urging force received from the urging member 81 and the friction is reduced. Therefore, if the slide member 21 continues to receive a strong braking force, the moving speed of the slide member 21 and the card 101 is excessively decelerated, and the card 101 may be discharged.

  Therefore, in the present embodiment, the braking force received from the braking member 66 is reduced between the first convex portion 21h1 and the second convex portion 21h2, thereby preventing the card 101 from being discharged. Yes.

  Subsequently, the slide member 21 and the card further move to reach between the terminal discharge position and the card temporary holding position as shown in FIG. The temporary card holding position is a position where the slide member 21 stops, as will be described later.

  When the slide member 21 is in the position as shown in FIG. 8, the sliding portion 66a of the braking member 66 is in contact with the surface of the second convex portion 21h2. That is, it is in contact with a high part of the braking surface. Therefore, the slide member 21 receives a strong braking force in a range where the second convex portion 21h2 exists.

  After passing through the terminal discharging position, the contact pad 151 of the card 101 is not in contact with the tip 51b of the terminal 51, and therefore is not subjected to friction from the tip 51b. Therefore, since the difference between the urging force received from the urging member 81 and the friction is slightly large, the moving speed of the slide member 21 and the card 101 may become too high.

  Therefore, in the present embodiment, the sliding portion 66a of the braking member 66 is brought into contact with the surface of the second convex portion 21h2 disposed on the back side of the first convex portion 21h1, and the slide member 21 is made to be the braking member. The braking force received from 66 is increased, thereby effectively reducing the moving speed of the slide member 21 and the card 101 and preventing the card 101 from jumping out of the card connector 1. Yes.

  By the way, when the part where the sliding part 66a abuts on the braking surface changes from the surface of the braked part 21g to the surface of the second convex part 21h2, that is, the sliding part 66a is on the front side of the second convex part 21h2. When contacting the end (the left end in FIG. 8), the braking force increases stepwise, so the slide member 21 may receive a very strong braking force. However, as described above, at this time point, the dynamic friction is small and the inertia is generated, and the biasing member 81 formed of a coil spring generates a certain level of biasing force. Therefore, even if the slide member 21 receives a very strong braking force from the slide portion 66a, the slide member 21 and the card 101 do not stop. Further, by appropriately changing the front side end of the second convex part 21h2 and / or the shape of the sliding part 66a, for example, by making the front side end of the second convex part 21h2 into a curved surface or an inclined surface, Further, for example, by reducing the inclination of the outer shape of the sliding portion 66a or increasing the curvature, the braking force when the sliding portion 66a abuts on the near side end of the second convex portion 21h2 is reduced. You can also.

  Then, after the slide member 21 and the card 101 are further moved toward the front side by the biasing force of the biasing member 81, the slide member 21 comes into contact with the stopper portion 11g formed on the second side wall portion 11d. It stops at the card temporary holding position as shown in FIG. Since the posture of the slide member 21 changes at the temporary card holding position, the engagement between the first engagement portion 21c and the second engagement portion 21d of the slide member 21 and the engagement portion of the card 101 becomes loose. . Therefore, although the card 101 is temporarily held by the slide member 21, if the user pulls the card 101 with fingers or the like, the holding by the slide member 21 is released even if a strong pulling force is not applied. It is in a state to be.

  When the slide member 21 is in the card temporary holding position, the sliding portion 66a of the braking member 66 is not in contact with the surface of the braked portion 21g. That is, the rear side end (the right side end in FIG. 9) of the braked portion 21g is positioned on the near side of the sliding portion 66a. Even when the length of the braked portion 21g is extended and the slide member 21 is in the card temporary holding position, the rear side end of the braked portion 21g is positioned on the back side of the sliding portion 66a. The sliding portion 66a can be in contact with the surface of the braked portion 21g. That is, when the slide member 21 is in the card temporary holding position, the sliding portion 66a is not in contact with the braking surface or is in contact with a lower portion of the braking surface.

  Therefore, the slide member 21 does not receive a braking force or receives a weak braking force even if it is received in the card temporary holding position and the vicinity thereof. Therefore, the urging force of the urging member 81 is not attenuated at all or almost by the braking force from the braking member 66.

  When the slide member 21 is in the card temporary holding position and the range in the vicinity thereof, the biasing member 81 made of a coil spring is hardly compressed and has a length close to the free length. Has not occurred.

  Therefore, if the braking force from the braking member 66 is large, the slide member 21 and the card 101 may stop. That is, the discharge property of the card 101 is lowered, and in the worst case, the card 101 may not be discharged.

  For example, in the conventional card connector described in the “Background Art” section, the braking force exerted by the braking shoe 819 is when the memory card 901 is ejected from the housing 811, that is, the slide member 821 reaches the closest side. When the contact portion 821e contacts the stopper portion 811g, the maximum is achieved. In this case, since the coil spring 881 has a length close to the free length and its repulsive force is minimum, the braking force exerted by the brake shoe 819 overcomes the repulsive force of the coil spring 881, and the memory card 901. Is not likely to be discharged from the housing 811.

  On the other hand, in the present embodiment, the slide member 21 does not receive a braking force when it is in the temporary card holding position and the vicinity thereof, or even receives a weak braking force even if it is received. The urging force of the urging member 81 is not reduced at all or almost. Thereby, even if the urging force received from the urging member 81 is small, the slide member 21 and the card 101 can reach the temporary card holding position without stopping. That is, the discharge property of the card 101 is not lowered.

  As described above, when the slide member 21 is immediately before reaching the temporary card holding position and the range in the vicinity thereof, that is, at the lock position and before and after the lock position, the sliding portion 66a of the braking member 66 is the second convex portion. Since the upper surface of 21h2 is in contact with the high portion of the braking surface, the moving speed of the slide member 21 and the card 101 is effectively reduced. Therefore, when the slide member 21 is in the card temporary holding position and the vicinity thereof, the card 101 jumps out of the card connector 1 even if it receives no braking force or only receives a weak braking force. There is no end to it.

  Also, when the slide member 21 comes into contact with the stopper portion 11g and stops, the moving speed is effectively decelerated, so that a large impact does not occur.

  In the present embodiment, the braking member 66 is formed on the top plate portion 62 of the shell 61, the upper surface of the braked portion 21g functions as a braking surface, and the upper surface of the braked portion 21g. Although only the example in which the first convex portion 21h1 and the second convex portion 21h2 are formed has been described, the braking member 66 is formed on the side plate portion 64 of the shell 61, and the side surface of the braked portion 21g functions as a braking surface. And the 1st convex part 21h1 and the 2nd convex part 21h2 may be formed in the side surface of the to-be-braking part 21g.

  Further, in the present embodiment, only the case where there are two convex portions formed on the braked portion 21g, the first convex portion 21h1 and the second convex portion 21h2, has been described. For example, the number may be any number, for example, three or four.

  Further, in the present embodiment, the description of the change in the braking force applied from the braking member 66 to the braked portion 21g when the card 101 is inserted into the card connector 1 is omitted. This is because the card 101 is almost affected by the braking force because the force with which the user inserts the card 101 with a finger or the like is sufficiently larger than the braking force or the urging force of the urging member 81. It is because it is inserted in the connector 1 for cards, without. Therefore, even when a braking force is applied from the braking member 66 to the braked portion 21g, the operability when the card 101 is inserted into the card connector 1 is not deteriorated.

  Thus, in the card connector 1 according to the present embodiment, the shell 61 is a cantilever-like braking member 66 in which the base end is integrally connected to the shell 61 and the sliding portion 66a is formed at the free end. The slide member 21 includes a braked portion 21g including a braking surface with which the sliding portion 66a can come into contact, and a first convex portion 21h1 and a second convex portion 21h2 are formed on the braking surface. As a result, an appropriate magnitude of braking force can be stably exerted at an appropriate timing regardless of the external finishing accuracy of the card 101. Therefore, the card 101 can be reliably and stably discharged at an appropriate speed. Further, the card 101 does not fly out. Furthermore, the structure is simple and the number of parts does not increase. Therefore, manufacture is easy, cost can be reduced, and reliability can be improved.

  Further, when the card 101 is in the overstroke position, the sliding portion 66a abuts on the front side of the braking surface in the insertion direction of the card 101 with respect to the first convex portion 21h1, and when the card 101 is in the locked position. , Abuts on the surface of the first convex portion 21h1. Thereby, at the initial point of the step of discharging the card 101, the slide member 21 only receives a weak braking force, so that the discharging property of the card 101 does not deteriorate. Further, when the slide member 21 is in the locked position, the urging force of the urging member 81 is greatly reduced by the braking force, so that the moving speed of the slide member 21 and the card 101 is effectively reduced, and the card 101 is moved to the card 101. It can prevent jumping out from the connector 1 for power.

  Further, when the slide member 21 ejects the card 101, the slide member 21 comes into contact with the stopper portion 11g of the housing 11 and stops, and the slide portion 66a stops when the slide member 21 comes into contact with the stopper portion 11g and stops. Abutting on the rear side of the card 101 in the insertion direction of the card 101 relative to the second convex portion 21h2 on the braking surface, or abutting on the braking surface located on the rear side of the card 101 in the insertion direction of the card 101. do not do. As a result, when the slide member 21 is in contact with the stopper portion 11g and stopped, the slide member 21 does not receive the braking force, or even if it receives, the biasing member 81 receives only a weak braking force. The urging force is not attenuated at all or hardly by the braking force. Therefore, the discharge property of the card 101 is not lowered.

  Further, when the card 101 is ejected, the sliding portion 66a is in a position where the connection between the contact pad 151 and the terminal 51 is released, and the first convex portion 21h1 and the second convex portion on the braking surface. It is in contact with the portion between the portion 21h2 and without the first and second convex portions 21h1 and 21h2. Thereby, when the contact pad 151 of the card 101 is in contact with the terminal 51 and is subjected to friction, the braking force can be reduced, so that the discharging property of the card 101 does not deteriorate.

  Further, when the card 101 is ejected, the sliding part 66a comes into contact with the stopper part 11g provided in the housing 11 and the position at which the card 101 is disconnected from the contact pad 151 and the terminal 51. The second projection 21h2 comes into contact with the surface of the second projection 21h2. Accordingly, when the contact between the contact pad 151 of the card 101 and the terminal 51 is released and no friction is applied, the braking force can be increased, so that the card 101 jumps out of the card connector 1 vigorously. This can be prevented.

  In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.

  The present invention can be applied to a card connector.
