Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a card connector to which a card-shaped medium such as an SD (square digital) card or an IC card can be inserted and connected.
[0002]
[Prior art]
Conventionally, as a card connector, a card connector is configured with a connector for connection and a cover member such as a metal shell, and when the card is inserted into the container from the insertion slot, the card contacts with the contacts of the card at the insertion completed position. A connector for a card in which the terminals of the connector are engaged (for example, Japanese Patent Application Laid-Open No. 8-293006) is known.
[0003]
There is also known a card connector in which a holder (slide housing) is slidably mounted on a chassis (base housing), the card is held by the holder, and the card can be inserted with the slide of the holder (see FIG. 1). JP-A-2001-60253). A toggle spring is installed between the holder and the chassis so that the biasing direction is reversed in the middle of the slide of the holder, and the slide spring can be slid in the latter half of the slide of the holder by the elasticity of the toggle spring. A connector for connection is provided on the chassis, and when the card that slides with the holder comes to the connection position, the contact of the card and the terminal of the connector are engaged.
[0004]
In the case of a structure in which the holder is slidably installed on this chassis, a connector for connection is installed in the holder so that the contacts of the card and the terminals of the connector engage when the card is held in the holder. It has been proposed (JP-A-2001-135411). In the case where a connector for connection is provided on this holder, the connector and the chassis or the board on which the chassis is mounted are connected by a flat flexible cable such as an FPC. Therefore, when the holder slides, the flat flexible cable is routed. In addition, when the holder is slid, it is necessary to ensure that the card and the connector for connection are securely connected. Therefore, the holder is provided with a regulating member that engages with the chassis side. The restriction member was disengaged.
[0005]
[Problems to be solved by the invention]
In the conventional card connector as described above, a connector for connection is installed in the holder, and a flat flexible cable such as an FPC is connected to this connector. Since the cables are routed, it is necessary to secure a sufficient space for routing the flat flexible cable in the card connector. For this reason, when the size and height of the card connector are reduced, the space for routing is a design constraint. In addition, when the flat flexible cable is routed, a stress is applied to a connection portion with a connector for connection, that is, a soldered portion, and peeling of the soldered portion is caused, so that there is a problem that reliability is impaired. Furthermore, the installation of the restricting member for restricting the slide of the holder complicates the structure of the card connector.
[0006]
The present invention has been made in view of such a problem, and is a card connector in which a slide housing is slidably mounted on a base housing, and is easily adapted to miniaturization, reduction in height, and the like. A first object is to provide a card connector having a configuration that can improve reliability. It is a second object of the present invention to provide a card connector having a simple structure for restricting the slide of the slide housing when inserting a card.
[0007]
[Means for Solving the Problems]
The present invention made for the above purpose comprises a base housing, and a slide housing slidably mounted on the base housing between a card insertion position and a connection position,
The slide housing is provided with a card receiving cavity, a contact piece facing the card receiving cavity and capable of engaging with a contact of a card, and a terminal including a contact piece disposed outside the slide housing. Is provided,
The base housing is provided with a terminal having a contact piece that engages with a contact piece disposed outside the slide housing when the slide housing slides to the connection position,
A locking piece that engages with an engagement shoulder provided on the base housing to limit sliding of the slide housing at the insertion position toward the connection position, and that protrudes from the side into the card receiving cavity; A lock terminal having a side end surface of the card and a protrusion which can slide and contact the card,
When the card is inserted into the slide housing at the insertion position and the contacts of the card and the contact pieces that can engage with the contacts of the card are engaged, the side end surface of the card makes the protrusion of the lock terminal into the card receiving cavity. The lock connector is pushed out of the lock terminal to elastically deform the lock terminal, so that the lock piece of the lock terminal is disengaged from the engagement shoulder to release the restriction on the slide, and is a card connector.
[0008]
[Action]
According to the card connector of the present invention configured as described above, when the slide housing is slid to the connection position, the terminal provided on the slide housing and the terminal provided on the base housing engage, and the card and the base housing are connected. Circuits on a circuit board to be mounted can be electrically connected. Since there is no flat flexible cable such as FPC that is routed by the slide of the slide housing, there is no need to secure a space for routing the flat flexible cable, and it is easy to reduce the size and height. To In addition, it is possible to eliminate lack of reliability due to routing of the flat flexible cable.
[0009]
Further, the lock terminal provided on the slide housing is configured to elastically deform by interfering with the side end surface of the card and release the restriction on the slide, so that when the card is pulled out from the slide housing, the lock terminal returns elastically. The state where the slide is restricted can be set again. The sliding of the slide housing can be restricted with a simple configuration in which only one lock terminal is provided.
[0010]

It is possible to engage. Further, a boss 20 for engaging with a positioning hole (not shown) on the circuit board 51 side is protrudingly provided on the bottom surface of the base housing 10.
[0014]
The slide housing 30 includes an insulating housing 32 formed of an insulating resin, and a metal plate shell 33 covered by the insulating housing 32. The shell 33 includes a top plate 34 that covers the upper side of the insulating housing 32 and side plates 35 that hang down from both side edges of the top plate 34. Are united. The side plate 35 is longer than the height of the insulating housing 32, extends to the base housing 10, and an engaging edge 37 formed by bending a lower edge inwardly engages with the notch groove 19 formed in the base housing 10. (FIG. 3), the slide housing 30 can slide on the base housing 10 in the front-rear direction. The arm 31 extends from one side plate 35 of the shell 33.
[0015]
The insulating housing 32 constituting the slide housing 30 is formed in a substantially U-shape with a terminal mounting portion 38 and a pair of side walls 39 facing each other. The space between them is a card insertion slot 41. When a card 70 (here, an SD card is shown) is inserted into the insertion slot 41 through the opening 55 of the housing 50, the card 70 is guided by the inner wall of the side wall 39 and inserted into the card accommodating cavity 40. It has become.
[0016]
A terminal mounting groove 42 is formed in the terminal mounting portion 38 of the insulating housing 32 so as to correspond to the base terminal 14 on the base housing 10 side, and a slide terminal 43 is mounted in each terminal mounting groove 42. The slide terminal 43 is also formed by punching a thin metal plate, and as shown in FIG. 2, a first contact piece 45 folded in a horizontal U-shape extends from the rear end of the mounting piece 44, The second contact piece 46 also has a shape extending in a cantilever shape from the front end of 44. When the mounting piece 44 is engaged with the terminal mounting groove 42 and mounted, the first contact piece 45 is received in the contact receiving groove 47 formed on the lower surface of the terminal mounting portion 38 and is flush with the bottom surface of the insulating housing 32. The second contact piece 46 extends into the card accommodating cavity 40 so that the contact portion 48 can be engaged with the contact 71 of the card 70 inserted into the card accommodating cavity 40.
[0017]
As described above, the slide housing 30 slidably mounted on the base housing 10 is basically slid by a pushing force given via the card 70 or a pullback force given via the slider 54. However, a spring member that can bias the slide of the slide housing 30 is further provided. In this embodiment, a toggle spring 90 capable of reversing the biasing direction is used as a spring member.
[0018]
As shown in FIG. 2, a spring member accommodating recess 21 is provided near the front end 13 of the base housing 10 for the toggle spring 90, and the toggle spring 90 is accommodated therein. In order to lock the first arm 91 and the second arm 92 of the toggle spring 90, a fixed boss 93 is provided on the base housing 10 side, and a slide boss 94 is provided on the slide housing 30 side. The fixed boss 93 is provided upward in the spring member accommodating recess 21, and the slide boss 94 is provided downward on the bottom surface of the insulating housing 32. The positional relationship between the fixed boss 93 and the slide boss 94 is such that the fixed boss 93 and the slide boss 94 are aligned in a horizontal line when the slide housing 30 slides substantially at the center of the slide range (see FIG. 12).
[0019]
As shown in FIG. 1, an elongated groove-shaped lock terminal housing concave portion 60 is formed on one side wall 39 (left side in the figure) of the insulating housing 32 constituting the slide housing 30 along the side wall 39. A lock terminal 80 for restricting the slide of the slide housing 30 is provided in the lock terminal receiving recess 60. 7 to 9 are enlarged views of the installation portion of the lock terminal 80. One end (front end) of the lock terminal housing recess 60 is narrowed to form a mounting groove 61 for the lock terminal 80, and an opening 62 penetrating toward the base housing 10 is formed at the bottom at the other end. ing. A notch opening 63 communicating with the card housing cavity 40 is formed in an intermediate portion of a wall that partitions the card housing cavity 40 and the lock terminal housing recess 60.
[0020]
Like the base terminal 14 and the slide terminal 43, the lock terminal 80 is formed by punching a thin metal plate, and is formed from a mounting piece 81 which is mounted and fixed in the mounting groove 61 of the lock terminal receiving recess 60. 82 has an elongated shape. The working beam 82 has an intermediate portion corresponding to the notch opening 63 formed in an arc shape to form a projection 83, and the projection 83 projects into the card housing cavity 40 through the notch opening 63. A lock piece 84 hangs down from the tip of the working beam 82. The lock piece 84 has a length that protrudes toward the base housing 10 through the opening 62 formed in the bottom of the lock terminal receiving recess 60 and protrudes into the slide groove 22 formed in the base housing 10 (FIG. 8). reference).
[0021]
When the protrusion 83 formed in the working beam 82 and projected to the card housing cavity 40 through the cutout opening 63 is pushed out of the card housing cavity 40, the working beam 82 is elastically deformed in a direction away from the card housing cavity 40, When the force for pushing the projection 83 is removed, the operating beam 83 is elastically restored, and the projection 83 projects again into the card accommodating cavity 40. The locking piece 84 moves in the opening 62 in accordance with the deformation and return of the operating beam 82.
[0022]
The slide groove 22 formed in the base housing 10 for receiving the lock piece 84 protruding from the slide housing 30 has an inverted L-shape as shown in FIG. The slide housing 30 includes a long groove portion 22a along the sliding direction of the slide housing 30 and a short groove portion 22b which is substantially perpendicular to the long groove portion 22a. The short groove portion 22b has substantially the same size as the rectangular opening 62 formed in the lock terminal receiving recess 60, and the slide housing 30 is located on the front end 13 side of the base housing 10 (card insertion position). At times, the short groove portion 22b and the opening 62 overlap each other.
[0023]
Thus, when the slide housing 30 is located on the front end 13 side of the base housing 10 and the projection 83 of the lock terminal 80 projects into the card accommodating cavity 40, the lock piece 84 of the lock terminal 80 becomes the short groove of the slide groove 22. The slide housing 30 protrudes into the portion 22b and engages with the engagement shoulder 23 formed by the inner wall of the short groove portion 22b so that the slide housing 30 can be restricted from sliding toward the rear end 11 of the base housing 10. Have been.
[0024]
Next, the operation when inserting and connecting the card 70 into the card connector configured as described above will be described with reference to FIGS. As shown in FIG. 1, when the slide housing 30 is at the insertion position on the front end 13 side of the base housing 10 and the card 70 has not yet been inserted into the card accommodating cavity 40 (the state where the card has been removed in FIG. 1), As described above, the lock piece 84 of the lock terminal 80 is engaged with the engagement shoulder 23 of the slide groove 22, and the slide of the slide housing 30 toward the rear end 11 is restricted. Further, since the slide boss 94 engaged with the arm of the toggle spring 90 is closer to the front end 13 than the fixed boss 93, the slide housing 30 is urged toward the front end 13 by the elastic force of the toggle spring 90.
[0025]
The card 70 is inserted into the card housing cavity 40 through the insertion opening 41 into the slide housing 30 in such an initial state. Since the slide of the slide housing 30 is restricted, the card 70 can be inserted securely until the front end face 72 of the card housing 70 contacts the inner end face 40 a of the card housing cavity 40. FIG. 1 shows a state where the card 70 is inserted into the slide housing 30 at the insertion position in this manner. When the card 70 is inserted until the front end surface 72 of the card 70 comes into contact with the inner end surface 40 a of the card housing cavity 40, the second contact piece 46 of the slide terminal 43 facing the card housing cavity 40 in a cantilever shape is lowered by the card 70. As a result, the contact portion 48 and the contact 71 of the card 70 are reliably engaged with an appropriate contact pressure (FIG. 2).
[0026]
FIGS. 10 and 11 show the operation of the lock terminal 80 when the card 70 is inserted into the slide housing 30 in which the slide is restricted. That is, when the card 70 is inserted until the front end surface 72 thereof comes into contact with the inner end surface 40a of the card housing cavity 40, the side end surface 73 of the card 70 pushes the projection 83 of the lock terminal 80 out of the card housing cavity 40. Act on. That is, the position at which the projection 83 projects corresponds to the final position of the portion of the side end face 73 of the card 70 near the front end. When the projection 83 of the lock terminal 80 is pushed out in this way, the working beam 82 is elastically deformed as shown in the figure, and the engagement between the lock piece 84 and the engagement shoulder 23 is released as shown in FIG. The restriction of the slide by the lock terminal 80 is released.
[0027]
After the card 70 has been inserted as described above, the card 70 can be slid rearward by further pushing the card 70 rearward with a force that overcomes the urging force of the toggle spring 90. The lock piece 84 of the lock terminal 80 moves in the long groove portion 22 a of the slide groove 22. FIG. 12 shows the middle of the sliding of the card 70 and the slide housing 30. In this process, the slide boss 94 provided on the slide housing 30 also moves rearward, so that the toggle spring 90 displaces the directions of the first and second arms 91 and 92 while accumulating a resilient force.
[0028]
As shown in FIG. 12, when the card 70 is pushed further beyond the position where the slide boss 94 and the fixed boss 93 are aligned in a horizontal line, the slide boss 94 moves forward from the fixed boss 93, and at this point, the toggle spring The biasing direction of 90 is reversed. The slide housing 30 is biased rearward by the toggle spring 90. As a result, the card 70 moves rearward together with the slide housing 30 so as to be sucked.
[0029]
The toggle spring 90 slides the slide housing 30 to the connection position shown in FIGS. When the slide housing 30 slides to this connection position, the first contact piece 45 of the slide terminal 43 exposed on the bottom surface of the slide housing 30 is connected to the base terminal 14 on the base housing 10 side as shown in FIG. The contact piece 16 is lowered so as to ride on the contact piece 16, and the contact portion 18 and the second contact piece 46 are engaged with an appropriate contact pressure to be electrically connected. As a result, the circuit in the circuit board 51 to which the base terminal 14 is connected (soldered) can be electrically connected to the card 70.
[0030]
The removal of the card 70 can be performed via the slider 54. When the slide housing 30 is slid from the connection position in FIG. 13 to a position slightly beyond the intermediate position in FIG. 12, the biasing direction of the toggle spring 90 is reversed again, and the biasing force of the toggle spring 90 causes the slide housing 30 and the card 70 Can be slid to the insertion position of FIG. In the state shown in FIG. 1, the base end of the card 70 protrudes from the opening 55 of the housing 50, so that the card 70 can be taken out by holding the base end. When the card 70 is removed from the card accommodating cavity 40, the pushing force of the projection 83 of the lock terminal 80 is removed, and the operating beam 82 returns to the state shown in FIGS. Therefore, the lock piece 84 is engaged again with the engagement shoulder 23 of the slide groove 22, and the slide of the slide housing 30 is restricted.
[0031]
FIG. 15 and FIG. 16 show a second embodiment. This embodiment differs from the first embodiment only in the shape of the base terminal 14A and the slide terminal 43A. Therefore, when the slide housing 30 is at the insertion position (FIG. 15) and when the slide housing 30 is at the connection position (FIG. 16). Are only cross-sectional views. The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
[0032]
In the base terminal 14A mounted on the base housing 10, the mounting piece 15A mounted on the terminal mounting groove 12 of the base housing 10 and exposed on the upper surface also constitutes a contact piece. On the other hand, in the slide terminal 43A mounted on the slide housing 30, the first contact piece 45A folded back in a horizontal U-shape at the rear end of the mounting piece 44A extends obliquely downward and in a cantilever manner, The slide housing 30 has a shape facing downward from the lower surface.
[0033]
In the second embodiment, when the slide housing 30 slides to the connection position in FIG. 16, the first contact piece 45A of the slide terminal 43A rides on the mounting piece 15A also serving as the contact piece of the base terminal 14A. Then, the first contact piece 45A and the mounting piece 15A are electrically engaged with an appropriate contact pressure.
[0034]
Next, FIGS. 17 to 19 show a third embodiment. In this embodiment, the thickness of the base housing 10B is reduced, and a toggle spring 90 for urging the slide housing 30B is provided outside the base housing 10B, that is, on the circuit board 51. Therefore, the fixed boss 93B is provided on the circuit board 51, and the slide boss 94B is provided on the horizontal tab 49 provided on the shell 33B of the slide housing 30B.
[0035]
The base terminal 14B provided on the base housing 10B has a contact piece 16B extending in a cantilever shape along the upper surface of the base housing 10B and formed in an arc shape. It is pin-shaped so that dip soldering can be performed. The slide terminal 43B provided on the slide housing 30B is configured such that the second contact piece 46B extends substantially horizontally toward the rear, and when the slide housing 30B slides to the connection position, the second contact piece 46B is brought into contact with the contact piece 16B of the base terminal 14B. It is designed to ride on the arcuate curved part of. The other parts are substantially the same as those of the first embodiment, and therefore, the same parts are denoted by the same reference numerals and description thereof will be omitted.
[0036]
This embodiment is also the same as described above, with the contact 71 of the card 70 and the slide terminal 43B engaged with the slide housing 30B at the insertion position in the drawing, and then sliding the slide housing 30B to the connection position. Then, the card 70 and the circuit board 51 can be finally connected by engaging the slide terminal 43B and the base terminal 14B.
[0037]
【The invention's effect】
As described above, according to the present invention, when the slide housing slides to the connection position, the terminal of the slide housing and the terminal of the base housing are engaged with each other, so that the flat flexible cable routed by the slide of the slide housing.
