Description

  The present invention relates to a card connector for connecting a card such as an IC card to a board, and a card connector with a take-out mechanism capable of taking out the card with a simple operation and detecting the card insertion / removal state associated therewith. About.

  Conventionally, in this type of card connector with a take-out mechanism, a card-like body such as a card tray containing a card can be taken out from the housing by operating a push pin (for example, Patent Document 1), or a so-called push A device that can take out a card-like body from a housing by an in-push-out method (for example, Patent Document 2) is known.

  On the other hand, this type of card connector is known to have a detecting means for detecting the insertion / removal state of the card-like body with a switch that is switched in conjunction with the movement of the card-like body in the insertion / extraction direction (for example, Patent Document 3), this detection means is used for switching control of the live / inactive state of the signal transmission contact with respect to the signal transmission terminal of the card.

  For example, as shown in FIG. 11, the detection means includes an operation side switch contact 101 disposed in the connector width direction on the back side of the card insertion unit 100, and the card-like body insertion direction back side of the operation side switch contact 101. And the operated switch contacts 102 and 103 arranged on the front side, respectively, and the operating switch contact 101 operates in conjunction with the movement in the insertion / removal direction of the card-like body 104 composed of a card or a card tray containing the card. Then, the switch contacts 102 and 103 to be operated are brought into contact with or separated from each other, that is, the switches are switched, and the insertion / removal state of the card-like body 104 can be detected step by step by the switch switching operation.

  That is, this detection means is in a state where the operation side switch contact 101 shown in FIG. 11A is in contact with only the operated side switch contact 102 (initial state), and in contact with the card-like body 104 shown in FIG. However, the operating side switch contact 101 is pushed into the card-like body 104 shown in FIG. 11C when the operating side switch contact 101 is detached from the operated side switch contacts 102 and 103 (first detection state) and FIG. The state (second detection state) in contact with the operated switch contact 103 can be detected.

  It should be noted that the time (timing) in switching the switch is performed in conjunction with the movement of the card-like body 104 in the insertion / removal direction, so the distance between the operated switch contacts 102 and 103 and the card-like body It is determined by the insertion / extraction speed of 104.

Japanese Patent Laid-Open No. 10-189139 JP 2000-251025 A JP 2004-235160 A

  However, in the conventional technology as described above, if the time (timing) in switching the switch is short, there is a possibility that the switch is not accurately detected, for example, from the first detection state to the second detection state described above. In the operation up to, the timing of switching from the first detection state to the second detection state, that is, the operation side switch contact 101 is separated from the operation side switch contact 102 and then contacts the operation side switch contact 103. If the time until is short, the first detection state cannot be detected, and it may be erroneously detected that the initial detection state has been switched directly to the second detection state.

  Therefore, in such a card connector, it is necessary to provide a sufficient margin for the switching timing of the switch or to perform processing by a logic circuit in consideration of the above-mentioned problems. Had to rely on complicated circuits, and there was a problem that the cost increased accordingly.

  On the other hand, in order to provide a sufficient margin for the switch switching timing, since the insertion / extraction speed is an unstable parameter that changes depending on the force of the person performing the card insertion / extraction operation, etc., the switch contact on the operated side Therefore, there is a problem in that the overall distance between the connectors is increased, which leads to an increase in the size of the entire connector.

  Furthermore, when hot-plugging the card-like body with respect to the connector (equipment to which the connector is attached), switching between live and non-live lines between the signal transmission terminal of the card and the signal transmission contact of the connector is as described above. Since the detection switch operates in conjunction with the movement in the card insertion / removal direction, the position of the signal transmission terminal relative to the signal transmission contact when the detection switch operates is performed based on the detection signal obtained from the detection means. Also changes.

  Therefore, if the operation of the detection switch is slightly delayed from the timing of detachment of the signal transmission contact with respect to the signal transmission terminal of the card, the card is taken out even though the card and the connection board are still in the live state. There is a possibility that troubles such as erasing information stored on the card may occur.

When the card tray 1 is further pushed in, the rotation lever 26 is rotated by being pushed by the card tray 1, and the operation rod 20 starts moving toward the front side in the insertion / removal direction in conjunction therewith. At this time, as in the initial state, the insertion / extraction direction detection switch 40 is still on and the width direction detection switch 41 is off.

  Then, when the card tray 1 is further pushed in to reach a predetermined position, the rear edge portion of the card tray 1 or the card A accommodated in the card tray 1 contacts the contact portion 47 of the insertion / extraction direction operation side switch contact 42, By pushing the insertion / removal direction operation side switch contact 42, the insertion / removal direction operation side switch contact 42 operates toward the rear side in the insertion / removal direction, whereby both contact portions 48 and 51 are separated and the insertion / removal direction detection switch 40 is moved. It becomes an off state (first detection point).

  Next, when the card tray 1 is inserted to a predetermined storage position, that is, a position where the signal transmission terminal 3 of the card A and the signal transmission contact 4 exposed in the card-like body insertion portion 15 are in contact with each other, FIG. As shown in FIG. 3, the operating rod 20 is pushed by the turning lever 26 and the slide guide protrusion 23 moves to a position where the vertical groove 24b and the horizontal groove 24a intersect with each other, and the return spring 25 and the width direction operation side. When pressed by the switch contact 55, the operating rod 20 rotates inwardly in the connector width direction (card tray 1 side) with the rotation shaft 21 as a base, and as shown in FIG. 8 fits into the engagement recess 9 of the card tray 1, and the operation switch switch 55 for the width direction operates toward the inner side in the connector width direction by its own elasticity, so that the contact portions 62 and 64 are brought into contact with each other. Direction inspection Switch 41 is turned on (second detection point).

  The time until switching from the first detection point to the second detection point, that is, the switching timing is the time until the trailing edge of the card tray 1 contacts the operated switch contact and moves to a predetermined storage position. And the time during which the operating rod 20 is rotating (the time during which the slide guide protrusion 23 moves from one end to the other end of the lateral groove 24a), it is possible to ensure a time that can be reliably detected. it can.

  Further, the rotation of the operation rod 20 toward the inner side in the connector width direction is not linked to the movement of the card tray 1 in the insertion / removal direction, and the time depends only on the length of the lateral groove 24a and the urging force by the return spring 25. So it is stable.

  On the other hand, in order to take out the card tray 1 from the card connector, at the second detection point shown in FIG. 9A, first, when the operation pin 11 is inserted from the insertion hole 10, the tip of the operation pin 11 is moved. It contacts the guide taper portion 29. At this time, the slide guide protrusion 23 is inserted into the lateral groove 24a, and the movement of the operation rod 20 in the insertion / extraction direction is restricted. Acting outwardly in the connector width direction with respect to the guide taper portion 29, the operating rod 20 rotates around the rotation shaft 21 toward the outer side in the connector width direction.

  Then, as shown in FIG. 9B, when the operation rod 20 is rotated, the outer surface of the operation rod 20 comes into contact with the contact portion 60 of the operation switch switch 55 for the width direction, and the operation for the width direction is performed. The side switch contact 55 is pushed toward the outer side in the connector width direction, whereby both contact portions 62 and 64 are separated from each other, and the width direction detection switch 41 is turned off (first detection point).

  At this time, if the detection switch 41 for the width direction can be switched without moving the card tray 1 in the insertion / extraction direction, and the control of the hot insertion / extraction is performed based on the signal, the switching timing of the live line / non-hot line However, the timing at which the signal transmission terminal 3 is detached from the signal transmission contact 4 is not delayed.

  Further, the rod 11 is guided by the guide taper portion 29 by pushing in the operation pin 11, the tip portion of the operation pin 11 is inserted between the operation rod 20 and the guide wall 16, and separated from the engagement recess 9. At the same time, the slide guide protrusion 23 moves to the outer end of the lateral groove 24a, and the operation rod 20 is movable in the insertion / removal direction.

  Then, by further pushing the operation pin 11, the operation rod 20 slides toward the back in the insertion / removal direction while guiding the rotation shaft 21 into the slide groove 22 and the slide guide protrusion 23 into the vertical groove 24b. Accordingly, one end portion 26 a of the rotation lever 26 is pushed toward the back side in the insertion / removal direction, the rotation lever 26 rotates about the pivot shaft 28, and the other end portion 26 b of the card tray 1. Press the trailing edge toward the exit direction.

  In conjunction with the movement of the card tray 1 in the removal direction by the turning lever 26, the insertion / extraction direction operation side switch contact 42 operates in the extraction direction by its own elasticity, and when it moves to a predetermined position, both contact portions 48 are provided. , 51 come into contact with each other, the insertion / extraction direction detection switch 40 is turned on, and the initial state is restored.

  Instead of the above-described embodiment, the operating rod 20 is urged toward the front side in the insertion / removal direction of the card tray 1 by an urging means such as a return spring (not shown), and the initial state is shown in FIG. That is, both the insertion / extraction direction detection switch 40 and the width direction detection switch 41 may be turned on.

  In this case, when the card tray 1 is inserted, the engaging protrusion 8 is pushed by the inclined portion formed at the rear edge of the card tray 1, so that the operation rod 20 rotates outward in the connector width direction. In conjunction with this, the width direction detection switch 41 is turned off, and the state shifts to the state shown in FIG.

  When the card tray 1 is taken out, the operation pin 11 and the card tray 1 are removed from the housing 2 from the state shown in FIG. The operating rod 20 is returned to the initial position shown in FIG.

  In the above-described embodiment, an example in which a rotating lever is used as the take-out means has been described. However, the take-out means is not limited to the above-described embodiment. For example, the take-out means moves in the housing direction together with the card-like member. It has a slider, a return spring that urges the slider in the pushing direction, and a lock mechanism that restricts the movement of the slider at a predetermined storage position. In addition, the slider may be such that the card-like member is pushed out in the direction of withdrawal.

  Moreover, although the above-mentioned Example demonstrated the example using the card tray which accommodates a card | curd inside as a card-shaped object, the card | curd may be made to insert directly in a connector without using a tray. .
