[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an IC card mounting device.

[0002]

[Prior art]

 A conventional IC card mounting device will be described below.

17 to 19 show a conventional IC card mounting device. In the figure, the IC card mounting device 1 is composed of an ejector 2 and a pin header 7. The ejector 2 is integrally formed with an ejector body 3 and guide portions 4a and 4b. The slider guide groove 5 is formed in the guide portions 4a and 4b. An IC card guide groove 9 is provided, and a slider 6 is slidably inserted in the slider guide groove 5. Further, the ejector 2 is provided with an operation mechanism 8 for retracting the slider 6 together with the IC card.

Further, one end of a metal stopper 9a for preventing the IC card from jumping out is press-fitted into the IC card guide groove 9 of the guide portions 4a and 4b of the ejector 2, and the other end is spring-like. It has a shape that contacts the side of the IC card when the IC card is inserted. Further, as shown in FIG. 20, the stopper 9a may be formed integrally with the guide portions 4a and 4b of the ejector 2 by molding.

The IC card mounting device 1 connects the terminals 7a of the pin header 7 to the board to mount the pin header 7 on the board, and the IC card is mounted on the guide portions 4a and 4b of the ejector 2 using the IC card guides. It is used by inserting it into the groove 9 and connecting the connector of the IC card to the contact part 7b of the terminal 7a of the pin header 7. When the IC card is taken out, the slider 6 is retracted by the operating mechanism 8 of the ejector 2 to remove the IC card. It has been taken out.

[0006]

[Problems to be solved by the device]

 However, in the above-described conventional configuration, since the stopper 9a is press-fitted into the guide portions 4a and 4b as a separate metal part, a component tolerance between the stopper 9a and the press-fitted portions of the guide portions 4a and 4b is required, and There was a problem that the number of points increased and assembly man-hours increased, resulting in cost increase. Further, in the case where the stopper 9a is integrally molded with the guide portions 4a and 4b by molding, the spring property is weak and there is a problem that the braking function for preventing the IC card from popping out too much is not fulfilled. Was there.

The present invention solves the above-mentioned problems of the related art, does not require component tolerances, reduces the number of components, and reduces the number of assembly steps, thus reducing the cost, and also causing the IC card to pop out too much. It is an object of the present invention to provide an IC card mounting device that sufficiently fulfills the function of preventing the above.

[0008]

[Means for Solving the Problems]

 In order to achieve this object, the IC card mounting device of the present invention is mounted on the board and positioned on the inner surface of the left and right guide parts of the ejector connected to the pin header which is connected to the connector of the IC card. It has a structure in which a stopper, which is biased by a spring on the side surface of the IC card when the IC card is inserted, is projectingly provided on the edge.

[0009]

[Action]

 With this structure, the stoppers are projected on both side edges of the slider integrally with the slider, so only the component tolerances of the stopper are required and machining is easy, and no separate components are required, and the number of components is reduced to assemble. The number of man-hours is reduced, and thus the cost is reduced. Moreover, since the stopper and the slider are integrally formed of the same metal as the slider, the spring property is good and the braking function to prevent the IC card from popping out too much can be fully achieved.
