Description

  The present invention relates to a card connector for inserting and inserting a card into a housing, and relates to a card connector provided with a lever-operated detection switch for detecting insertion of a card in the housing.

  This type of conventional card connector is provided with an insulating lever that is directly pressed by the card and rotated, and a biasing member that biases the lever in the direction of a predetermined initial posture. A wall surface standing from the bottom of the housing is provided at the front end of the housing in the card insertion direction. The lever is provided with a movable conductive portion so as to be rotatable integrally with the lever. The movable conductive portion is positioned away from the wall surface in a state where the lever is in the initial posture, and comes into contact with the wall surface as the lever is turned by the card. The wall surface includes first and second fixed conductive portions arranged at intervals in the width direction of the housing. The movable conductive portion is always in conduction with the first fixed conductive portion, and comes into contact with the second fixed conductive portion as the lever is turned by the card. That is, the lever, the urging member, the movable conductive portion, the first fixed conductive portion, and the second fixed conductive portion constitute a detection switch that detects card insertion in the housing.

  Each of the urging member and the movable conductive portion is composed of a separate conductive torsion spring. These torsion springs are arranged side by side in the longitudinal direction of the lever so as to be elastically deformed in a direction parallel to the bottom of the housing. Here, the torsion springs constituting the urging member are referred to as urging torsion springs, and the torsion springs constituting the movable conductive portion are referred to as movable torsion springs, and these torsion springs will be described.

  The urging torsion spring is provided between the housing and the lever so as to urge the lever in the direction of the initial posture, and one arm portion is held in a state of being in constant contact with the first fixed conductive portion. ing. The movable torsion spring is electrically connected to the other arm portion of the biasing torsion spring in one arm portion, and is thus always in communication with the first fixed conductive portion.

  The other end of the movable torsion spring is located away from the second fixed conductive portion in a state where the lever is in the initial posture. When the lever is pressed by the card and rotated, the lever rotates by a predetermined angle from the initial posture (rotation angle 0 °), that is, when the card is inserted to a predetermined position with respect to the housing. The other arm portion is in contact with the second fixed conductive portion, whereby the first and second fixed conductive portions are conducted through the biasing torsion spring and the movable torsion spring. That is, insertion of a card is detected. Thereafter, the movable torsion spring is elastically deformed by pressing the other arm portion against the second fixing member, thereby allowing the card to rotate the lever, that is, to move the card forward from a predetermined position. The

  As described above, in the detection switch in the conventional card connector, when the card is inserted to a predetermined position in the housing, the movable conductive portion comes into contact with the second fixed conductive portion and turns on. Then, the card is allowed to be inserted forward of a predetermined position by elastic deformation of the movable torsion spring.

  For the detection switch of the card connector, it is desired to improve the degree of freedom in setting the position for detecting the card (hereinafter referred to as “detection position”). In the above-described conventional card connector detection switch, when the detection position is changed in the direction opposite to the card insertion direction, the other end of the movable torsion spring and the second fixed conductive portion when the lever is in the initial posture. It is conceivable to extend the other end of the movable torsion spring so that the distance to In this case, the amount of movement in the card insertion direction with respect to the housing required for card insertion does not change even if the detection position is changed. Therefore, the detection position in the housing is shifted by the amount opposite to the insertion direction. The amount of card movement from to the front is longer. Along with this, as the movable torsion spring, one that can be elastically deformed to allow the amount of movement of the long card must be used, and the movable torsion spring was used before shifting the detection position. The number of windings is increased compared to the one. In order to use the movable torsion spring having an increased number of turns, it is necessary to enlarge the housing in order to secure a storage space for the movable torsion spring. This is not preferable because it is contrary to the recent trend of miniaturization of card connectors.

  The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to provide a card connector that can improve the degree of freedom in setting the detection position of the card without increasing the size of the housing. It is in.

  The present invention is configured as follows to achieve the above-described object.

[1] The present invention includes a housing in which a card is inserted and a lever-operated detection switch that detects the card in the housing, and the detection switch is pressed directly or indirectly by the card. An insulating lever that is rotated, a biasing member that biases the lever in a predetermined initial posture direction, and a movable conductive member that rotates integrally with the lever and rotates along the bottom of the housing. A first fixed conductive portion that stands up with respect to the bottom of the housing at the front end of the housing in the card insertion direction and is always in conduction with the movable conductive portion, and within the rotation range of the movable conductive portion A second fixed conductive portion provided on the bottom side of the movable conductive portion, and a position adjacent to the second fixed conductive portion on the bottom side of the housing within the rotation range of the movable conductive portion. And having an insulating part to be
The arrangement of the second fixed conductive portion and the insulating portion is such that the movable conductive portion contacts the second fixed conductive portion from an off state where the detection switch contacts the insulating portion as the lever rotates. Set to change to the on state, or to change from the on state to the off state,
The card connector according to claim 1, wherein the on state or the off state is associated with a state where the card is in a predetermined position with respect to the housing.

  In the present invention described in “[1]”, the movable conductive portion rotates integrally with the lever and rotates along the bottom portion of the housing. The second fixed conductive portion and the insulating portion are located adjacent to each other on the bottom side of the housing within the rotation range of the movable conductive portion. Accordingly, it is possible to allow the movement in the card insertion direction after the card is detected without the elastic deformation of the movable conductive portion. Therefore, the degree of freedom in setting the detection position of the card can be improved without increasing the size of the housing.

[2] In the present invention according to [1], the biasing member is a conductive torsion spring, and one arm portion of the torsion spring is always electrically connected to the first fixed conductive portion. The other arm portion is electrically connected to the movable conductive portion.

  According to the present invention described in “[2]”, the torsion spring as the urging member also serves as a member for electrically connecting the first fixed conductive portion and the movable conductive portion, thereby reducing the number of parts. Can contribute.

[3] The present invention is characterized in that, in the invention described in “[2]”, the movable electric part is formed integrally with the other arm part of the torsion spring.

  According to the present invention described in “[3]”, it is not necessary to use a separate member from the torsion spring as the movable conductive portion, which can contribute to a reduction in the number of parts.

[4] In the present invention according to “[2]”, the movable conductive portion is separate from the torsion spring, and the movable conductive portion is provided with the torsion against an elastic force of the torsion spring. A locking portion for locking the other arm portion of the spring is formed.

  According to the present invention described in “[4]”, the lever does not need to be provided with a locking portion for the other arm portion of the torsion spring. Further, since the other arm portion of the torsion spring is pressed against the engaging portion of the movable conductive portion by the elastic force of the torsion spring, the movable conductive portion and the torsion spring can be reliably conducted. Furthermore, since a member for conducting the movable conductive portion and the torsion spring is not required, it is possible to contribute to the reduction of the number of parts.

[5] In the present invention according to any one of “[1]” to “[4]”, the detection switch includes a plurality of the first and second fixed conductive portions. The plurality of second fixed conductive portions and the insulating portions are alternately arranged, and the movable conductive portion is in contact with each of the plurality of second fixed conductive portions. Each is characterized by forming a different conductive path.

  According to the present invention described in “[5]”, different electrical signals can be generated in each of the ON states in which the movable conductive portion is in contact with each of the plurality of second fixed conductive portions. Therefore, the card can be detected for each of a plurality of predetermined positions of the card with respect to the housing.

[6] In the present invention according to [5], the arrangement of the plurality of second fixed conductive portions and the insulating portion includes a first conductive path associated with an initial posture of the lever, The lever is set to form a second conductive path associated with a full operation posture in which the lever is rotated from the initial posture to the limit angle in the insertion direction.

  According to the present invention described in “[6]”, since the first conductive path is formed, it can be detected that the card is not in a position to operate the lever. Further, since neither the first conductive path nor the second conductive path is formed after the first conductive path is formed, it can be detected that the card is in the initial operation position where the lever in the initial posture starts to rotate. Further, since the second conductive path is formed from the state where neither the first or second conductive path is formed, it can be detected that the card is at the insertion limit position.

  According to the present invention, as described above, the degree of freedom in setting the detection position of the card can be improved without increasing the size of the housing.

Each of the terminals of the terminal row 5 is a terminal of the terminal row of the card 40 in a state where the card 40 is located at a mounting position (a position shown in FIG. Pressed against each of the.

  As shown in FIGS. 2 and 3, a lever-operated detection switch 10 that detects the card 40 in the housing 2 is provided at the front end in the housing 2 in the insertion direction of the card 40. The detection switch 10 includes a lever 11 that is directly pressed by the card 40 and is rotated in the insertion direction. This lever 11 is an insulator made of synthetic resin. A shaft insertion portion 11 a that forms a cylindrical surface that opens on the lower side is formed at one end portion of the lever 11 in the longitudinal direction. At the left end of the front end portion of the housing body 3, a rotating shaft portion 12 is formed so as to protrude upward from the bottom portion 3a. The lever 11 is rotatably supported with respect to the housing body 3 by inserting the rotation shaft portion 12 into the shaft insertion portion 11a. Further, the flange portion 11 b protrudes from one end portion of the lever 11. The housing main body 3 is formed with a blocking portion 13 that overlaps with the flange portion 11b from above and blocks the upward movement of the flange portion 11b. Further, the blocking portion 13 prevents the end portion of the lever 11 on the side opposite to the shaft insertion portion 11a side from rattling in the direction approaching the bottom portion 3a of the housing body 3 by blocking the upward movement of the flange portion 11b. It is preventing.

  As shown in FIGS. 4-2 and 4-3, the lever 11 is formed with a shaft portion 11c protruding downward. As shown in FIG. 5, a movable range defining portion 19 is formed on the bottom portion 3 a. The movable range defining portion 19 is an arc-shaped long hole around the rotation shaft portion 12. A shaft portion 11c is inserted into the movable range defining portion 19, and the movable range of the lever 11 is defined by defining the movable range around the rotating shaft portion 12 of the shaft portion 11c. The shaft portion 11 c is inserted into the coil portion 14 a of the conductive torsion spring 14. An arm portion 14b forming one end side of the torsion spring 14 extends from the lower portion of the coil portion 14a. As shown in FIG. 4A, the arm portion 14 b protrudes to the front side of the lever 11. The arm portion 14b is bent with its front side as a mountain fold side.

  From the upper part of the coil part 14 a, an arm part 14 c that forms the other end side of the torsion spring 14 extends along the longitudinal direction of the lever 11. A movable conductive portion 15 extends in the longitudinal direction of the lever 11 from the tip of the arm portion 14c. The movable conductive portion 15 is bent with the bottom 3a side (lower side) of the housing body 3 as a mountain fold side. The top portion 15 a of the movable conductive portion 15 is located in contact with the bottom portion 3 a of the housing body 3. The arm portion 14c and the movable conductive portion 15 as a whole constitute a cantilever-like spring whose fixed end is the end portion on the coil portion 14a side, and the top of the movable conductive portion 15 is formed by the elastic force of this spring. 15 a is pressed against the bottom 3 a side of the housing body 3.

  As shown in FIG. 4-3, a regulating portion 11 d that regulates the rotation of the torsion spring 14 around the shaft portion 11 c relative to the lever 11 is formed at the end of the lever 11 opposite to the shaft insertion portion 11 a side. Yes. This restricting portion 11 d is a recess that is recessed toward the shaft insertion portion 11 a of the lever 11, and the end of the movable conductive portion 15 opposite to the arm portion 14 c is inserted. The inner wall surface on the rear side of the restricting portion 11d locks the rearward rotation of the torsion spring 14 with respect to the lever 11. The inner wall surface on the front side of the restricting portion 11d locks the forward rotation of the torsion spring 14 with respect to the lever 11.

  As shown in FIG. 3, at the front end of the housing 2, a first fixed conductive portion 16 is provided upright with respect to the bottom portion 3 a of the housing body 3. The mountain fold side of the arm portion 14b of the torsion spring 14 is always in contact with the first fixed conductive portion 16 from the rear. As a result, the first fixed conductive portion 16 and the movable conductive portion 15 are always conductive. The first fixed conductive portion 16 is formed integrally with the external terminal 20 protruding from the front end of the housing body 3, and is fixed to the housing body 3 by insert molding.

  The torsion spring 14 is prevented from moving forward by the arm portion 14b by the first fixed conductive portion 16, and is also prevented from rotating around the shaft portion 11c relative to the lever 11 by the restricting portion 11d. It functions as an urging member that urges in the direction of a predetermined initial posture (the posture shown in FIG. 2) (see FIGS. 6-1 to 6-3).

  As shown in FIGS. 5 and 6-1 to 6-3, the bottom 3 a portion of the housing body 3 within the rotation range of the movable conductive portion 15 includes a plurality of, for example, two second fixed conductive portions 17 A and 17 B. , And the insulating portion 18. That is, two second fixed conductive portions 17 </ b> A and 17 </ b> B are provided for the movable conductive portion 15 and the first fixed conductive portion 16. The second fixed conductive portions 17A and 17B and the insulating portions 18 are alternately arranged. The second fixed conductive portions 17A and 17B are integrally formed with the external terminals 21 and 22 protruding from the front end of the housing body 3, and are fixed to the housing body 3 by insert molding. The insulating portion 18 is a part of the resin that forms the housing body 3. In the first ON state in which the movable conductive portion 15 is in contact with the second fixed conductive portion 17A, a first conductive path through which the external terminal 20 and the external terminal 21 are conducted is formed. In the second ON state in which the movable conductive portion 15 is in contact with the second fixed conductive portion 17B, a second conductive path through which the external terminal 20 and the external terminal 22 are conducted is formed. The first conductive path is associated with a state where the posture of the lever 11 is the initial posture (the posture shown in FIG. 2). The second conductive path is associated with a state in which the lever 11 is in the full operation posture in which the lever 11 is rotated from the initial posture (turning angle 0 °) to the limit angle as shown in FIG.

  A discharge mechanism 30 for the card 40 is provided on the right side of the housing body 3. The discharge mechanism 30 has a slider 31 slidable in the insertion direction and the discharge direction of the card 40 in the housing 2, and the direction of the slider 31 between the housing body 3 and the slider 31 in the initial position (position shown in FIG. 2). And a heart-shaped cam mechanism 33 that enables the slider 31 to be locked and unlocked by pushing the card 40.

  The slider 31 has a pressed operation portion 31 a that protrudes on the insertion track of the card 40. When the pressed operation portion 31 a is pressed by the front end portion of the card 40, the slider 31 moves in the insertion direction integrally with the card 40 against the elastic force of the return spring 32. Although not shown, the slider 31 is provided with a mechanism for suppressing movement of the card 40 in the ejecting direction with respect to the slider 31 in a state where the front end portion of the card 40 is in contact with the pressed operation portion 31a.

  The heart-shaped cam mechanism 33 has a heart-shaped cam groove 33a formed in the slider 31 and one end that moves along the heart-shaped cam groove 33a, and is rotatably supported by the housing body 3 on the other end side. And a rotation pin 33b. As shown in FIG. 1, a leaf spring portion 34 is formed on the cover member 4. The leaf spring 34 presses the rotating pin 33b from above, and presses one end of the rotating pin 33b against the bottom of the heart-shaped cam groove 33a.

  The operation of the card connector 1 according to this embodiment configured as described above will be described with reference to FIGS. 6-1 to 6-3 and FIGS. 7-1 to 7-3.

  When the user inserts the card 40 into the housing 2 through the insertion slot 2a, the front end of the card 40 comes into contact with the pressed operation portion 31a of the slider 31 at the initial position, as shown in FIG. At this time, the lever 11 is not rotated by the front end portion of the card 40. That is, in the detection switch 10, the lever 11 is in the initial posture, and as shown in FIG. 6A, the movable conductive portion 15 is in the first on state in which the movable conductive portion 15 contacts the second fixed conductive portion 17A, that is, the first fixed state. The conductive portion 16 and the second fixed conductive portion 17A are in a conductive state.

  Thereafter, the user continues to press the card 40 in the insertion direction. As a result, as shown in FIG. 7B, the card 40 and the slider 31 are integrally moved to the limit position in the insertion direction against the elastic force of the return spring 32. As described above, while the card 40 and the slider 31 move to the limit position, the lever 11 is pressed by the front end portion of the card 40 to be in the full operation posture in which the lever 40 is rotated from the initial posture to the limit angle in the insertion direction. As the posture of the lever 11 changes, the detection switch 10 moves from the first on state in which the movable conductive portion 15 contacts the second fixed conductive portion 17A as shown in FIG. In the second state when the movable conductive portion 15 is in contact with the second fixed conductive portion 17B, that is, the first fixed conductive portion 16 as shown in FIG. 6B. And the second fixed conductive portion 17B are in a conductive state.

  When the card 40 is inserted to the limit position of the housing 2 as described above, the user stops applying the pressing force in the insertion direction to the card 40. Along with this, the slider 31 and the card 40 are pushed and moved in the discharge direction by the elastic force of the return spring 32. As a result, the slider 31 moves to the mounting position as shown in FIG. 7C, and is locked and stopped by the heart-shaped cam mechanism 33 against the elastic force of the return spring 32 at this mounting position. Along with this, the card 40 is also stopped, and the mounting of the card 40 to the housing 2 is completed. Thus, until the card 40 moves in the ejection direction and stops, the lever 11 is permitted to rotate in the initial posture direction by the movement of the card 40 in the ejection direction, and is caused by the elastic force of the torsion spring 14. Then, the card 40 is rotated in the direction of the initial posture, and then the rotation of the card 40 in the direction of the initial posture is blocked by the front end portion of the card 40 and stopped against the elastic force of the torsion spring 14. At this time, the movable conductive portion 15 is in contact with the insulating portion 18 to form an off state of the detection switch 10.

  According to the card connector 1 according to the first embodiment, the following effects can be obtained.

  In the card connector 1, the movable conductive portion 15 is configured to rotate integrally with the lever 11 along the bottom portion 3 a of the housing body 3. The second fixed conductive portions 17 </ b> A and 17 </ b> B and the insulating portion 18 are positioned adjacent to each other on the bottom 3 a side of the housing body 3 within the rotation range of the movable conductive portion 15. Accordingly, it is possible to allow the movement of the card 40 in the insertion direction after the detection of the card 40 without the elastic deformation of the movable conductive portion 15. Therefore, the degree of freedom in setting the detection position of the card 40 can be improved without increasing the size of the housing 2.

  In the card connector 1, the torsion spring 14 as an urging member also serves as a member for conducting the first fixed conductive portion 16 and the movable conductive portion 15, which can contribute to a reduction in the number of parts.

  In the card connector 1, the movable conductive portion 15 is formed integrally with the arm portion 14 c of the torsion spring 14. Thereby, since it is not necessary to use a member separate from the torsion spring 14 as the movable conductive portion, it is possible to contribute to the reduction of the number of parts.

  In the card connector 1, the detection switch 10 has two second fixed conductive portions 17A and 17B with respect to the movable conductive portion 15 and the first fixed conductive portion 16, and the second fixed conductive portions 17A and 17B and The insulating portions 18 are arranged alternately. Each of the first and second ON states in which the movable conductive portion 15 is in contact with each of the second fixed conductive portions 17A and 17B forms a different conductive path (first and second conductive paths). Thereby, a different electric signal can be generated in each of the first and second ON states. Therefore, it can be detected that the card 40 is not in a position to operate the lever 11 by the state where the first conductive path is formed. In addition, the card 40 is in the operation initial position where the lever 11 in the initial posture starts to rotate by the transition from the state where the first conductive path is formed to the state where neither the first or second conductive path is formed. It can be detected. Moreover, it can detect that the card | curd 40 exists in the limit position of insertion by the transfer from the state in which neither the 1st or 2nd conductive path is formed to the state in which the 2nd conductive path was formed.

  The present invention is not limited to the card connector 1 according to the first embodiment described above, and may be as follows.

  In the card connector 1 according to the first embodiment, the lever 11 is directly pressed by the card 40 to be rotated, but the configuration of the present invention is not limited to this. The lever may be indirectly pressed by the card, that is, the lever may be indirectly pressed and rotated by a member that operates as the card is inserted, for example, a slider of the ejection mechanism.

  Although the card connector 1 according to the first embodiment includes the two second fixed conductive portions 17A and 17B, the present invention does not limit the number of second fixed conductive portions. Only one of the second fixed conductive portions 17A and 17B may be provided. Further, the arrangement of the insulating portion 18 and the second fixed conductive portions 17A and 17B may be switched.

The top 53 a is pressed against the bottom 3 a side of the housing main body 3 by the elasticity of the movable conductive portion main body 53.

  The lever 50 has a locking protrusion 50a that protrudes downward at the end opposite to the shaft insertion portion 11a side in the longitudinal direction. At the end of the movable conductive portion main body 53 opposite to the support plate portion 52 side, a locked portion 54 adjacent to the locking protrusion 50a in the front is formed. The movable conductive portion 51 is in a state in which the backward movement around the shaft portion 11c is prevented by the backward movement of the locked portion 54 being locked by the locking protrusion 50a.

  The lever 50 has assembly protrusions 50b and 50c between the locking protrusion 50a and the shaft portion 11c. The assembly protrusion 50b is located in contact with the movable conductive portion main body 51 from the front, and the assembly protrusion 50c is inserted into the assembly hole 52a.
