Description

  The present invention relates to a card connector for connecting a card such as an IC card to a substrate, and relates to a card connector with a taking-out function that can take out the card by a simple operation.

  Conventionally, this type of card connector is known to have a take-out function that can take out a card-like member such as an IC card or a card tray containing the card from the housing by operating a push pin. (For example, Patent Document 1).

  For example, as shown in FIG. 10, the card connector with a taking-out function includes an extrusion arm 101 that is rotatably supported on the back side in the card insertion / removal direction of the housing 100, and one end of the extrusion arm 101 by a push pin 102. The pushing arm 101 is rotated by pushing the portion, and the other side 103 of the arm pushes the inner edge of the card tray 104 in the discharge direction.

Japanese Patent Laid-Open No. 10-189139

  However, in the conventional technology as described above, since it has a take-out mechanism consisting of an extrusion arm and a push pin for operating the extrusion arm, the entire outer shape of the connector, that is, the area occupied by the board to which the connector is attached increases. Along with that, there was a problem that the degree of freedom of design also decreased. On the other hand, if the outer shape of the pushing arm is reduced in order to reduce the size of the connector, there is a problem that the arm length necessary for discharging the card-like member with a sufficient pushing amount cannot be secured.

  Also, when pushing out the card-like member, the force applied by the operator is transmitted to the pushing arm via the push pin, so if the operator puts too much force, the card-like member will pop out vigorously and damage the card etc. There was a problem that there was a risk of inviting. Furthermore, there is a problem that a card-like member such as a tray may come out due to an impact caused by dropping or the like.

  Furthermore, since this type of connector has a take-out mechanism, there is a problem that the number of parts increases and the cost increases accordingly.
