BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card mounting device.

[0002]

2. Description of the Related Art A conventional IC card mounting apparatus will be described below.

20 to 22 show a conventional IC card mounting device. In the figure, an IC card mounting device 1 comprises an ejector 2 and a pin header 7, and the ejector 2 has an ejector body 3 and guide portions 4a, 4b integrally formed, and guide portions 4a, 4b have slider guide grooves 5 formed therein. And an IC card guide groove 9, and a slider 6 is slidably inserted into the slider guide groove 5. The slider 6 is provided on both sides of the front end of the slider 6.
Is formed at a right angle with respect to the surface. The ejector 2 is provided with an operation mechanism 8 for retracting the slider 6 together with the IC card.

A ground terminal 7c is press-fitted in the center of the pin header 7, and one end thereof is spring-biased so as to come into contact with the back surface of the IC card when the IC card is inserted. Further, a pin portion 7d that is connected to the board when the board is mounted projects from the back surface of the ground terminal 7c.

The IC card mounting apparatus 1 connects the terminal 7a of the pin header 7 to the board, mounts the pin header 7 on the board, and mounts the IC card on the guide section 4 of the ejector 2.
a, 4b, and inserts the connector of the IC card into the terminal 7a of the pin header 7.
When the IC card is taken out, the slider 6 is operated by the operating mechanism 8 of the ejector 2.
Is retracted and the IC card is taken out.

[0006]

However, in the above-mentioned conventional structure, since the hook portion 6a of the slider 6 is close to the contact portion 7b of the terminal 7a of the pin header 7,
The static electricity that flows from the human hand when the IC card is inserted
Before the C card comes into contact with the ground terminal 7c of the pin header 7, it passes through the outside of the IC card and the hook portion 6 of the slider 6
There is a problem that the circuit of the connector may be broken by dropping from a to the contact portion 7b of the terminal 7a of the pin header 7.

Further, the center portion of the pin header 7 into which the ground terminal 7c is press-fitted often has a thin mold, so that the press-fitting of the ground terminal 7c is not stable.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide an IC card mounting device which does not damage the circuit of the connector by surely discharging static electricity to the substrate side with a simple structure. To do.

[0009]

Means for Solving the Problems] IC card mounting apparatus of the present invention to achieve this object, a ground terminal, INSTALLATION
