However, in the configuration of the conventional card connector device, the contact (connector terminal) 52 held by the insulator (housing) 51 has a free end on which the contact 52a is formed with respect to the insertion direction of the card 20. Since the card 52 is formed so as to extend from the back to the front (in the direction of the card insertion slot), if the contact 52a is attached to the lower side of the card storage part for some reason, the card 20 is inserted. In addition, the tip of the card 20 and the tip of the contact 52a collide, and the contact 52 is buckled or deformed, resulting in poor contact.
In addition, when the tip of the contact 52 a is previously bent and protruded so as not to collide with the tip of the card 20, the contact 52 a protrudes from the insulator (housing) 51 when the card 20 is inserted. Therefore, there is a problem that the height of the insulator has to be set high so that the connector device becomes large.

  Therefore, the present invention solves the above-described problems, can prevent the contact portion of the contact terminal from buckling or deforming when the card is inserted, can improve the contact reliability of the contact portion, and downsize the connector device.

The upper case 2 is superposed on the upper side of the opening, and the housing 1a of the housing 1 is formed in the opening. In addition, a spring accommodating portion 3a that accommodates a biasing member 6 made of a coil spring that biases a slide member 10 to be described later in the card discharge direction is formed on one side of the lower case 3.

  A lock member 7 made of a metal wire slidably contacted with a heart-shaped cam groove 10b formed on one end side of a slide member 10 to be described later on the card insertion slot side on the front surface on the axis of the spring accommodating portion 3a. A shaft hole 3b whose one end is pivotally supported is formed. A support hole 3c is provided at the rear end of the lower case 3 so as to pivotally support a drive member 8 to be described later. The drive member 8 pivotally supported in the support hole 3c is rotated as the card 12 is inserted.

  As shown in FIGS. 13 and 14, the drive member 8 is made of an insulating material such as synthetic resin, and has an elongated arm portion 8 a and an operation portion 8 b provided to protrude from one end side of the arm portion 8 a. A first holding portion 8c formed of a columnar support shaft provided on the other end side of the operating portion 8b, and a hollow vertical wall-like second holding portion 8d provided at the approximate center of the arm portion are provided. Have.

  The drive member 8 is provided with a movable contact 9 made of a conductive metal wire and formed of a single torsion coil spring having two end winding portions. The movable contact 9 is formed with a first contact spring 9a and a second contact spring 9b that respectively extend from the two end turns. The movable contact 9 has a seat winding portion in which the first contact spring 9a is extended and held on a support shaft of the first holding portion 8c of the drive member 8, and a seat in which the second contact spring 9b is extended. The winding portion is held and attached within the hollow standing wall of the second holding portion 8 d of the driving member 8.

  The distal end of the support shaft of the first holding portion 8c of the drive member 8 is rotatably supported by a support hole 3c provided at the rear end portion of the lower case 3, and the support member 3c rotates. When the drive member 8 that is pivotally supported comes into contact with one end portion of the card 12 and is rotated when the card 12 is inserted, the movable contact 9 is rotated in accordance with the rotation of the drive member 8. The first and second contact springs 9a and 9b are in contact with the first and second fixed contacts 5a and 5b formed on the upper case 2.

  At this time, the drive member 8 pivotally supports the first holding portion 8c in the support hole 3c of the lower case 3 so that the first contact spring 9a is in contact with the first fixed contact 5a. The second contact spring 9b and the second fixed contact are formed so as to be urged, and hold the second holding portion 8d so as to be rotatable about the first holding portion 8c. 5b is arranged so as to be able to contact and separate.

  Thus, the drive member 8 has a first holding portion 8c that holds the end winding portion of the first contact spring 9a of the movable contact 9, and a second holding portion that holds the end winding portion of the second contact spring 9b. The holding portion 8d is provided, the first holding portion 8c is pivotally supported on the housing 1, and the first contact spring 9a is urged in contact with the first fixed contact 5a, and the second holding portion Since the second contact spring 9b and the second fixed contact 5b are arranged so as to be able to come into contact with and separated from each other, the movable contact 9 is securely attached. The first contact spring 9a and the second contact spring 9b can be urged independently of each other while being held by the drive member 8.

  Further, when the second contact spring 9b comes into contact with the second fixed contact 5b, the seat winding portion of the second contact spring 9b is twisted as the drive member 8 rotates, and this seat The second contact spring 9b is slidably contacted on the contact surface of the second fixed contact 5b by the twisting action of the winding portion.

  In this way, the second contact spring 9b is formed on the contact surface of the second fixed contact 5b by twisting the end winding portion of the second contact spring 9b as the drive member 8 rotates. Since they are in sliding contact with each other, when the contact portions are brought into contact with each other, a self-cleaning action in which the contact portions rub against each other is obtained, so that the reliability of contact can be improved.

  Further, the movable contact 9 is formed by first and second contact springs 9a and 9b having two end winding portions, and the first contact spring 9a is used to rotate the drive member 8 after the turning operation. A return spring is constituted, and the second contact spring 9b constitutes a spring for applying a contact pressure with the second fixed contact 5b.

  Thus, the first contact spring 9a constitutes a spring for returning the drive member 8, and the second contact spring 9b constitutes a spring for applying contact pressure with the second fixed contact 5b. Therefore, since the return spring and the contact pressure applying spring are formed by different contact springs, the contact pressure can be applied reliably, and the contact reliability can be improved.

  The slide member 10 is formed in an approximately L-shape from an insulating material such as a synthetic resin, and is movable in the insertion and ejection direction of the card 12 as the card 12 is inserted and ejected into the housing portion 1a of the housing 1. It is stored in. On one end side of the base portion of the slide member 10, a spring locking portion 10 a is formed in which one end portion of the biasing member 6 made of a coil spring housed in the spring housing portion 3 a of the lower case 3 is locked. ing.

  In addition, on one end side of the upper surface of the base portion, in cooperation with the lock member 7 pivotally supported at one end side in the shaft hole 3b of the lower case 3, the urging force of the urging member 6 is resisted. Thus, a heart-shaped cam groove 10b for holding the slide member 10 at the insertion position of the card 12 is formed. Further, a card abutting portion 10 c is provided on one end side of the slide member 10 so as to protrude from the base portion in a direction orthogonal to the card insertion direction and abut one end portion (front end portion) of the card 12.

  A cover member 11 made of a metal plate is attached on the upper surface side of the upper case 2 so as to cover the upper and lower cases 2 and 3. The cover member 11 is formed so as to cover the upper surface of the connector terminal 4 disposed in the housing portion 1a of the housing 1, and serves as a shield plate for preventing intrusion of radiation noise from the outside. Also plays.

  Further, a cut window portion 11a is formed on one side of the cover member 11, and a pressing piece 11b having a spring property is formed extending from one side of the cut window portion 11a in a cantilever shape. Yes. The pressing piece 11 b biases the lock member 7 pivotally supported by the lower case 3 to the heart-shaped cam groove 10 b of the slide member 10 through the notch 2 b of the upper case 2.

  Further, as shown in FIG. 15, a hook-shaped locking step portion 11 c that is bent downward is provided at the center portion of the cover member 11 on the card insertion slot side. Further, the locking step portion 11c is formed in a long width shape in a direction orthogonal to the card insertion direction. When the cover member 11 is attached so as to cover the housing 1, the locking step portion 11 c and the engaging recess 2 c provided in the central portion of the upper case 2 on the card insertion port side are engaged. Thus, the upper case 2 is restricted from being displaced (flexed) toward the storage portion 1a of the housing 1.

  Thus, when the card 12 is inserted, the upper case 2 is accommodated in the cover member 11 and the upper case 2 as the contact portion 4a is pushed up (due to the reaction due to the spring property of the connector terminal 4). Displacement of the upper case 2 when the contact portion 4a is pressed by the cover member 11 because the locking step portion 11c and the engagement concave portion 2c for restricting displacement (bending) toward the portion 1a are formed. Therefore, since it is not necessary to increase the thickness of the upper case 2 and it is not necessary to increase the height of the housing 1, the connector device can be reduced in size.

  Further, since the cover member 11 is formed of a metal plate, and the locking step portion 11c bent downward is formed on the metal plate, the metal cover member 11 can be simply provided with the locking step portion 11c. With the structure, the displacement of the upper case 2 can be regulated.

  Moreover, since the latching step part 11c and the engagement recessed part 2c were formed in the center by the side of the card insertion port of the cover member 11 and the upper case 2, the location where the upper case 2 is most displaced can be controlled. Thus, the displacement of the upper case 2 can be reliably controlled. Further, since the locking step portion 11c and the engaging recess 2c are formed in a long width in a direction orthogonal to the card insertion direction, the width of the restricting portion with respect to the displacement direction is widened, so that the strength is strengthened. The displacement of the upper case 2 can be reliably regulated.

  The card 12 is, for example, an RS-MMC card (reduce size-multimedia card), and an integrated circuit (IC) is housed therein, and is used as a recording medium. On one surface of the card 12, a plurality of external contact portions 12a are formed on one end side, and the external contact portions 12a are contact portions of the connector terminal 4 disposed in the housing portion 1a of the housing 1. By making contact with 4a, various information processing with an externally connected electronic device is performed.

  When the card 12 is inserted into the housing portion 1 a of the housing 1, the front end portion of the card 12 comes into contact with the card contact portion 10 c of the slide member 10, so that the slide member 10 is inserted along with the insertion of the card 12. It is formed to be movable in the direction.

Next, the operation when the card 12 is inserted into the connector device will be described with reference to FIGS.
When the card 12 is inserted, first, in the initial state shown in FIGS. 3 and 4, that is, when the card 12 is not inserted, the slide member 10 is moved in the card ejection direction by the urging force of the urging member 6. It is energized.

  Next, when the card 12 is inserted into the housing portion 1 a of the housing 1, the front end portion of the card 12 is held in contact with the card contact portion 10 c of the slide member 10. . At this time, the external contact portion 12 a of the card 12 is separated from the contact portion 4 a of the connector terminal 4. Further, the movable contact 9 which is a detecting means for detecting insertion of the card 12 is urged in the card ejection direction by the urging force of the first contact spring 9a as a return spring of the drive member 8. The first contact spring 9a and the first fixed contact 5a are in contact with each other, but the second contact spring 9b and the second fixed contact 5b are in a separated state (FIG. 5). FIG. 6).

  Next, when the card 12 is pressed in the card insertion direction, the slide member 10 can move in the insertion direction as the card 12 is inserted, and the slide member 10 resists the biasing force of the biasing member 6. Move in the card insertion direction. Then, the front end portion of the card 12 abuts on the operating portion 8b of the driving member 8 pivotally supported by the housing portion 1a of the housing 1, and the driving member 8 is applied to the biasing force of the first contact spring 9a. Rotate in the card insertion direction. At this time, as the slide member 10 moves, one end of the lock member 7 traces the heart-shaped cam groove 10b provided in the slide member 10 (see FIGS. 7 and 8).

  As described above, the connector terminal 4 has one end side extending from the card insertion port side of the upper case 2 toward the back, and the contact portion 4a is accommodated via the window hole portion 2a provided in the upper case 2. The other end is extended to the back of the upper case 2 along both side edges of the window hole portion 2a of the upper case 2 and protrudes outward of the housing 1. Since the connection terminal 4c is formed, the contact portion 4a of the connector terminal 4 can be formed extending from the card insertion opening side to the back, so that when the card 12 is inserted into the storage portion 1a, the card 12 Even if the tip comes into contact with the contact terminal 4, it bends upward (escapes) without difficulty, so that the contact part 4 a of the contact terminal 4 can be prevented from buckling or deforming, and the contact reliability of the contact part 4 a can be improved. It has become a thing.

  Further, since the contact portion 4a side of the connector terminal 4 extends from the card insertion port side of the upper case 2 toward the back, a guide piece for preventing buckling is extended to the tip of the contact portion 4a. Since there is no need to increase the height of the housing 1 because the guide piece or the like does not have to be protruded from the upper surface of the housing 1 when the card 12 is inserted, the connector device can be downsized. Become.

  Next, when the card 12 is further pressed in the card insertion direction, one end of the lock member 7 traces the heart-shaped cam groove 10b provided in the slide member 10 and is locked at the lock position. Is inserted into the card insertion position of the storage portion 1a of the housing 1. At this time, the external contact portion 12 a of the card 12 comes into contact with the contact portion 4 a of the connector terminal 4. At this time, the drive member 8 is rotated in the card insertion direction together with the insertion of the card 12, whereby the second contact spring 9b for applying contact pressure comes into contact with the second fixed contact 5b, and the movable contact 9 Then, the first and second fixed contacts 5a and 5b are electrically connected to each other, and insertion of the card 12 is detected (see FIGS. 9 and 10).

  In order to eject the card 12 from the state shown in FIGS. 9 and 10, the card 12 is further pressed once in the insertion direction, so that the lock member 7 is released from the locked position of the heart cam groove 10b, and the urging force is applied. The slide member 10 is moved in the card discharge direction by the urging force of the member 6, and the card 12 is discharged to the discharge position together with the slide member 10.

  In this way, the urging member 6 that urges the slide member 10 in the card ejection direction to the housing 1 and the slide member 10 at the card insertion position against the urging force of the urging member 6. Since the holding lock member 7 is provided, the card 12 can be easily discharged by using the urging force of the urging member 6 when the card 12 is discharged.

  In addition, detection means that is driven by one end of the card 12 to detect insertion of the card 12 includes first and second fixed contacts 5a and 5b provided in the housing 1, and the first and second The movable contact 9 is formed by a single torsion coil spring having two end winding portions, and the first fixed to the torsion coil spring. The first contact spring 9a and the second contact spring 9b are formed by forming a first contact spring 9a that contacts the contact 5a and a second contact spring 9b that contacts the second fixed contact 5b. Since each of the end portions is extended from a different end winding portion, the contact portion of the detection switch for detecting insertion of the card 12 is obtained by using different contact springs for the spring pressure for self-return of the contact spring and the contact pressure of the contact portion. So long time use Even the, will stand to the contact spring of the contact portion, the contact pressure is assumed to be enhanced contact reliability prevents decrease. Further, it is not necessary to increase the shape of the contact spring in order to increase the contact pressure, and the connector device can be miniaturized.

  In addition, the housing 1 includes the drive member 8 that rotates in contact with one end portion of the card 12, and the movable contact 9 is held by the drive member 8, so that the housing portion of the housing 1 is provided. Since it is pivotally supported by 1a, the insertion of the card 12 can be reliably transmitted to the movable contact 9 via the drive member 8, and the insertion detection of the card 12 is reliably performed. It has become something that can be.
