Japanese Patent Laid-Open No. 11-307191 (page 5-7, FIG. 10)

  In recent years, electronic devices in which this type of card connector device is incorporated tend to be miniaturized, and thus there is a demand for a smaller card connector device. There is a positioning presser spring that urges the card from the side. This presser spring is pushed and bent in the direction opposite to the biasing direction when the card is loaded or removed. In order to secure the installation space including the range, the width of the base member has to be widened, and this has been a factor that hinders downsizing of the entire connector device.

  The present invention has been made in view of such a state of the art, and an object thereof is to provide a card connector device suitable for miniaturization.

  In order to achieve the above object, a card connector device according to the present invention includes a base member made of a synthetic resin into which a card having a recess formed on the outer surface is loaded from above, and the card supported by the base member. And a plurality of terminal members electrically connected to each other, and the base member is provided with positioning protrusions that can be fitted into the recesses of the card.

  According to the card connector device configured as described above, since the positioning of the card can be performed by fitting the positioning protrusion of the base member into the concave portion of the card, the positioning presser spring that biases the card from the side. Is no longer necessary. Therefore, the lateral width of the base member can be reduced by an amount that can eliminate the installation space for the presser spring, and the entire connector device can be reduced in size.

  In the above configuration, when the recesses are formed at symmetrical positions on the left and right outer surfaces of the card, respectively, a pair of positioning protrusions that protrude in the opposite direction to the base member are provided. This is preferable because the card on the base member can be accurately positioned only by the positioning protrusion.

  Further, in the above configuration, when an inclined guide surface is formed on the upper edge portion of the positioning protrusion to slide the lower edge portion of the recess and guide the card downward, the card is mounted on the base member. At this time, since there is no possibility that the concave portion of the card is caught by the upper edge portion of the positioning protrusion, it is preferable that the card can be loaded smoothly.

  Further, in the above configuration, when the plurality of bulging portions for making point contact with the wall surface of the concave portion are formed on the positioning protrusion, the card mounted on the base member is accurately positioned without play. It is preferable because it becomes easy.

  In the above configuration, the base member is provided with a cover member attached to the base member so that the hinge can be opened and closed and moved back and forth in a closed position, and the cover member is locked to the base member by moving forward by a predetermined amount in the closed position. With this configuration, after the card is mounted on the base member with the cover member open, the cover member can be closed and moved forward by a predetermined amount so that the card can be locked. It can be stably held in the mounting position, improving usability. For example, the base member is provided with an engaging protrusion that protrudes from the back side of the positioning protrusion, and the cover member is provided with an elastic arm piece that extends along the side edge, and the elastic arm is moved when the cover member is advanced in a closed position. If the tip end of the piece gets over the engagement protrusion and is locked, the locked state of the cover member can be easily realized, and the positioning protrusion and the engagement protrusion formed back to back are sufficient. Since the wall thickness can be ensured, the mechanical strength of these engaging portions where a relatively large force is applied is increased and is not easily damaged.

  The card connector device of the present invention eliminates the need for a positioning presser spring that urges the card from the side by providing a positioning projection on the base member that can be inserted into the concave portion of the card loaded from above. Since the lateral width of the base member can be narrowed by the amount that the installation space for the presser spring can be omitted, downsizing of the entire connector device can be promoted.
