First, after first contact, the first power contact 2
By contacting the SIM card surface, the switch is turned off and the detection circuit is powered on.

On the other hand, when the card is removed, the first power supply contact 2 moves above the signal contact 3, so that the second contact is removed before the signal contact 3 is separated from the pad 21. The switch is turned on by contacting the power contact 4, the power of the detection circuit is cut off, and after the power is turned off, the contact between the signal contact 3 and the pad 21 is released.

In the above explanation, the contact portion 2 of the first power source contact 2 has a dimensional difference with respect to the card insertion direction.
Although the height of a is set to be lower than the height of the contact portion 3a of the signal contact 3, the contact portion 2a,
Even if the height of 3a is the same, the pad 21 of the SIM card
By increasing the thickness of the card, a dimensional difference with respect to the card insertion direction can be provided in the same manner as described above.

In the above, when the card is inserted,
First power contact 2 and second power contact 4
However, the first power contact 2 and the second power contact 4 may be in contact with each other when the card is inserted. In short, the signal contact and the card pad at the time of insertion are the first. If the power of the detection circuit is turned on after the contact with and the power of the detection circuit is turned off when the card is removed and the contact between the signal contact and the pad of the card is released, It is not limited to the configuration.

[0030]

As described above, according to the present invention, the signal contact and the switch circuit including the first and second power contacts are provided in a relatively small space, and further, the signal contact is provided. Since the contact and the first power supply contact are common parts, space saving of the device, cost reduction, and protection of the card are realized.

Further, the present invention has a structure for preventing the card from being inserted or removed while the power is still on by shifting the timing of contacting the card between the switch terminals for general signals, contacts and detection. A connector can be provided.
