## Abstract

A card connector with a card insertion detection mechanism has a first movable terminal, and a second movable terminal. An abutting portion located on the first movable terminal is engageable with a card upon insertion to displace the first movable terminal from the second moveable terminal, and is disengageable from the card upon removal. A cam portion of the first movable terminal is positioned to contact the second movable terminal, and wipe with the second movable terminal.

## Claims

### Claim 1

A card connector having a card insertion detection mechanism comprising:
a first movable terminal;
a second movable terminal;
an abutting portion of the first movable terminal being engageable with a card upon insertion to displace the first movable terminal from the second moveable terminal, and being disengageable from the card upon removal; and
a cam portion of the first movable terminal positioned to contact the second movable terminal, and wipe with the second movable terminal.

### Claim 2 (depends on 1)

The card connector according to claim 1, wherein during card insertion, the second movable terminal wipes the cam portion of the first movable terminal before displacement of the first movable terminal from contact with the second movable terminal.

### Claim 3 (depends on 1)

The card connector according to claim 1, wherein during card removal, the second movable terminal wipes the cam portion before the second movable terminal contacts the abutting portion.

### Claim 4 (depends on 1)

The card connector according to claim 1, wherein the first movable terminal is disposed on a shell covering at least a part of a housing, and the second movable terminal is disposed on the housing.

### Claim 5 (depends on 1)

The card connector according to claim 1, wherein a circuit is opened by the first movable terminal disengaging from the second moveable terminal when the card is inserted.

### Claim 6 (depends on 1)

The card connector according to claim 1, wherein a circuit is closed by the first movable terminal contacting the second moveable terminal when the card is removed.

### Claim 7

A card connector comprising:
a housing;
contacts;
a shell; and
a card insertion detection mechanism having
a first movable terminal;
a second movable terminal;
an abutting portion of the first movable terminal being engageable with a card upon insertion to displace the first movable terminal from the second moveable terminal, and being disengageable from the card upon removal; and
a cam portion of the first movable terminal positioned to contact the second movable terminal, and wipe with the second movable terminal.

### Claim 8 (depends on 7)

The card connector according to claim 7, further comprising a card ejection mechanism.

### Claim 9 (depends on 7)

The card connector according to claim 7, wherein the first moveable terminal is disposed on the shell.

### Claim 10 (depends on 7)

The card connector according to claim 7, wherein the second moveable terminal is disposed on the housing.

### Claim 11 (depends on 7)

The card connector according to claim 7, wherein a circuit is opened by the first movable terminal disengaging from the second moveable terminal when the card is inserted.

### Claim 12 (depends on 7)

The card connector according to claim 7, wherein a circuit is closed by the first movable terminal contacting the second moveable terminal when the card is removed.
