It is still difficult for Mc to be in contact with the first contact member 93. That is, even if the card M is inserted into the connector 9, it is difficult to press the connection terminal Mc toward the contact of the first contact 93.

Therefore, the connector 9 is configured to use a carrier (not shown) that holds the card M. This carrier has the same width as the outer width Sw of the card S, and has a predetermined thickness equal to the thickness St of the card S, so that the card M can be detachably held. Thereby, it is achieved that the connection terminal Mc of the card M with the carrier inserted into the first recess 911 can surely contact the first contact 93. In this way, the connector 9 can be shared by a plurality of types of cards having different outer dimensions, or thicknesses, and arrangement of connection terminals.

The bottom surface Bf abuts against the insulating block 8b, and the insulating block 8b tilts the signal contact 8s and the ground contact 8g. The dumped signal contact 8s and the ground contact 8g enter the opening 8H of the casing 5 deeper than the insulating block 8b, thereby avoiding contact with the first card C1. Thereby, the signal contact 8s and the ground contact 8g do not contact the bottom surface Bf of the first card C1, and damage of the signal contact 8s and the ground contact 8g can be prevented. In the state in which the first card C1 is inserted into the concave portion 51 of the casing 5, the first connection terminal 1ct is in contact with the first contact 7 (see FIG. 29(B)).

Referring to Fig. 30(A), when the second card C2 is inserted into the concave portion 51 of the casing 5, the step of the second groove portion D2 travels toward the insulating block 8b. Referring to Fig. 30(B), in a state where the second card C2 is inserted into the concave portion 51 of the casing 5, the insulating block 8b can pass without coming into contact with the bottom surface of the second groove portion D2. Further, the insulating block 8b does not cause the signal contact 8s and the ground contact 8g to be tilted, and the signal contact 8s and the ground contact 8g can be brought into contact with the second connection terminal 2ct. Further, in a state where the second card C2 is inserted into the concave portion 51 of the casing 5, the first connection terminal 1ct is in contact with the first contact 7 (see FIG. 30(B)).

As described above, the connector 20 of the second embodiment is configured such that the insulating blocks 8b are individually provided on the intermediate portions of the plurality of second contacts 8 to be protected. In a state in which the insulating block 8b abuts against the bottom of the card inserted into the casing 1, the insulating block 8b is pressed by the bottom of the card, and the plurality of second contacts 8 are tilted so as to be separated from the bottom surface of the card. Thereby, in the contacts of the card connector 20 which can correspond to different cards (C1, C2), it is possible to avoid the necessity of the corresponding card as much as possible. Partial contact outside the part. As a result, it is possible to provide a card connector which does not have the problem of damaging the contact.

Further, since the connector 20 of the second embodiment does not need to be provided with the pair of leaf springs 4a and 4a that support the insulating rod 4b, the connector 20 has a different configuration from the connector 10 of the first embodiment. Further, since the connector 20 of the second embodiment is provided with the insulating block 8b in the contact member itself, unlike the connector 10 of the first embodiment, it is not necessary to bring the pair of leaf springs 4a, 4a toward the signal contact member 4s. The effect of the 4s bending step.

In the connector 20 of the second embodiment, the insulating block 8b is separately provided in the intermediate portion between the signal contact 8s and the ground contact 8g, even if the electrode wall of the first card C1 is broken (see ninth). In other words, since the insulating block 8b can pass between the inter-electrode walls (see Fig. 29), it is possible to prevent the signal contact 8s and the ground contact 8g from being deformed differently from the connector 10 of the first embodiment.

The invention discloses a card connector which can share two types of cards having the same outer shape and thickness but different arrangement of a part of connecting terminals, and can protect the contact member, but can protect the card as long as the technical idea of the present invention is applied.
