Description

  The present invention relates to a card connector for connecting a card such as an IC card or a flash memory card to an electronic device, and more particularly to a card connector with a take-out mechanism provided with a card take-out mechanism.

  Conventionally, as this type of card connector, one having a take-out mechanism that can take out a card from a housing by operating a push bar is widely known (for example, Patent Document 1).

  The card connector take-out mechanism includes a turning lever that is rotatably supported on the back side in the card insertion / removal direction of the housing, and a push bar connected to one end of the turning lever. The push bar is inserted into the card. The card is slid in the direction and the one end of the pivot lever is pushed in so that the pivot lever is pivoted, and the back edge of the card is pushed out in the ejection direction at the other end of the pivot lever.

  That is, the push-in operation of the push bar is converted into a rotational force via the rotating lever, and the card is pushed out using the rotational force.

  In general, a metal plate material is used for the rotating lever used in the card removing mechanism from the viewpoint of strength.

Japanese Patent Laid-Open No. 10-189139

  However, in the conventional technology as described above, since one end of the rotation lever directly contacts the front edge of the card, the rotational force of the rotation lever is applied to the card in the pushing direction (card insertion / removal direction) and the card width direction. Therefore, there is a problem that the push-bar pushing operation cannot be efficiently transmitted to the force in the direction of pushing out the card.

  Further, in such a take-out mechanism, when the pivotable amount of the pivot lever is set to be large and one end side of the metal pivot lever reaches the contact, the pivot lever contacts the contact, There is a risk of short circuit between the contacts or between the contacts and other circuits via the rotating lever, and when the rotating lever and the contact are in contact, the direction intersecting the card insertion / removal direction with respect to the contact, that is, deformation There is a risk that the contact will buckle because a force in a direction that cannot be allowed to act acts.

  Therefore, in the prior art, the rotation amount (rotation angle) of the rotation lever is limited to avoid contact between the rotation lever and the contact. For this purpose, the card is pushed out by the rotation lever. There was a problem that the amount was also limited.

  Further, in the conventional technology, since one end of the rotating lever is in direct contact with the front edge of the card, the force accompanying the pushing operation of the push bar is directly transmitted to the card via the rotating lever. When the push bar is pushed in vigorously, the momentum is not attenuated and is transmitted to the card via the rotating lever, and the card pops out of the housing due to the momentum, and the card may be damaged.

  Furthermore, since the conventional rotating lever is not regulated in the connector thickness direction (free state), it may cause abnormal noise due to rattling or the like, and the rotating lever may contact the contact. There is a risk of contact and causing contact buckling.

  Therefore, in view of such a conventional problem, the present invention has been made for the purpose of providing a card connector with a take-out mechanism excellent in operability when a card body such as an IC card is inserted into and removed from the housing.

  In the card connector 1 configured as described above, when the card body A is inserted into the card insertion portion 2, as shown in FIG. 13 (a), the ejector 11 is at a desired card insertion position P1, and interlocked therewith. The position of the pivot lever 10 is such that the lever main body 31 is substantially parallel to the connector width direction and the pushed-in portion 32 protrudes into the push bar accommodating portion 16.

  In this state, the push bar 12 is urged by the spring body 66 and is located at the front end of the push bar housing portion 16, and the insertion portion 62 is inserted below the pushed portion 32. And is in a state where it can be pushed in.

  As shown in FIGS. 13A to 13B, when the push bar 12 is pushed from this state, the concave side surface 63a of the push bar 12 comes into contact with the push shaft 64 and further pushes the push bar 12. As shown in FIGS. 13B to 13C, the push bar 12 pushes one end of the rotating lever 10, that is, the pushed-in portion 32 to the back side.

  The pivot lever 10 whose end is pushed in this way pivots in the direction in which the ejector 11 moves to the card removal position P2 side with the pivot shaft 23 as a base axis, that is, here in the horizontal counterclockwise direction. In conjunction with this, the ejector 11 slides on the inner bottom surface of the card insertion portion 2 from the card insertion position P1 to the card removal position P2, and is pushed by the ejector 11 to push out the card body A.

  At that time, since the ejector 11 is connected to the tip of the rotating lever 10 so as to be relatively movable, the rotational movement of the rotating lever 11 is efficiently converted into a force in the card pushing direction, and the card body A can be pushed out. .

  Further, the rotating lever 10 is supported by the housing 3 via the ejector 11, and is always held at a position H2 higher in the connector thickness direction than the protruding height H1 of the elastic contact piece 50 of the contact 5, and contacts the rotating lever 10 5 is not in contact with the rotation lever 10 so that the rotation angle of the rotation lever 10 does not need to be limited, and the rotation lever 10 can reach the contact 5. 5 can be overlapped.

  In addition, the card body A can be pushed out in a large amount, and the card body A can be suitably taken out.

  Further, in this card connector 1, the insulating portion 42 is interposed between the contact 5 and the rotation lever 10, and the contact 5 and the rotation lever 10 are reliably insulated, so that the rotation lever 10 is placed on the contact 5. It is possible to prevent an unintended short circuit even when the rotary lever 10 is overlapped with the contact 5.

  Further, even when the rotation lever 10 and the contact 5 are overlapped, the rotation lever 10 and the contact 5 are not in contact with each other, and the ejector 11 (insulating portion) that may be in contact with the contact 5 is also possible. 20) always moves only in the card insertion / removal direction, so that an unintended force, that is, a force in the connector width direction does not act on the contact 5, so that the contact 5 can be prevented from buckling.

  Further, by providing the pressing portion 46 on the lower surface of the insulating portion, when the ejector 11 moves on the contact 5, the pressing portion 46 of the insulating portion 42 is in front of the elastic contact piece 51. Further, the inclined portion 46a comes into contact with the inclined surface, the lower end surface portion of the pressing portion 46 is guided to the contact portion 54, and is pushed down by the insulating portion 42, whereby the elastic contact piece portion 51 is elastically deformed.

  At this time, the contact 11 is elastically contacted with the insulating portion 42 in the ejector 11, thereby causing a resistance in the card insertion / removal direction. The resistance exerts a damper effect on the momentum of the rotation lever 10, and the rotation lever 10 The momentum during the push-in operation of the push bar 12 transmitted through the card can be preferably alleviated and the card body A can be prevented from popping out.

  On the other hand, when the removal of the card body A is completed, the push bar 12 is urged by the spring body 66 to return to the original position as shown in FIG.

  As described above, the push bar 12 is arranged so as to be detachable from the rotating lever 10 and the spring body 66 for urging the push bar 12 in a direction to be detached from the rotating lever 10 is provided. Since the push bar 12 is at the origin position where the push bar 12 can always be pushed regardless of the position of the rotation lever 10, it is possible to cope with an erroneous operation.

  In the above-described embodiment, the example in which the card as shown in FIG. 5 is used as the card body A has been described. However, the configuration of the card body is not limited to the above-described embodiment, and other cards such as a flash memory card are used. The card may be accommodated in a card tray or a card adapter.

  In the above-described embodiment, the example in which the ejector 11 is integrally provided with the insulating portion interposed between the contact 5 and the rotation lever 10 has been described. However, the form of the ejector 11 is not limited to this, for example, If the rotating lever 10 is held at a position H2 higher than the protruding height H1 of the elastic contact piece 50, the insulating portion 42 may not be provided, and the pressing portion 46 is not provided on the insulating portion 42, and Even if the insulating portion 42 is interposed between the moving lever 10 and the contact 5, the contact 5 may not be contacted.

  Further, the shapes of the contacts 4 and 5 are not limited to those shown in the above-described embodiments. For example, the contact 5 may be a cantilever spring like the contact 4, and all the same as the contact 5. It may have a U-shaped elastic contact piece.
