Travelling contact spring 206f shown in Fig. 7 (a), under the state that is maintained at spring maintaining part 206g, has a pair of 206j of foot, 206k to the fore-and-aft direction extension of connector 1.Along with the insertion of the 1st card A, press down parts 206 and rotate, by the 206j of foot, 206k being pressed into the expansion that is pressed on the base portion 201, contact with the 207a of fixed contact portion, 207b respectively.Thus, make to be conducting state between the 207a of fixed contact portion, 207b, the detection signal of the 1st card A becomes the signal of outside output.

The detecting unit of installation that detects the 1st card A like this is by the fixed contact 207 that is arranged on base portion 201 and remain on the travelling contact spring 206f that presses down in the parts 206 and constitute.And the insertion that this detecting unit constitutes along with the 1st card A is operated, and therefore, becoming to detect the installation of the 1st card A in linkage reliably with the installation of the 1st card A.

Below, the action during for the 1st card A of installation in the connector 1 with said structure and the 2nd card B describes.Fig. 8 and Fig. 9 are the sectional side views of the connector 1 of this implementation method.Fig. 8 is the figure that the action when the 1st card A is installed in connector 1 is described.In Fig. 8 (a), the status of processes of the 1st card is installed in expression, and in Fig. 8 (b), the state behind the 1st card A has been installed in expression.And Fig. 9 is the figure that the action when the 2nd card B is installed in connector 2 is described.The status of processes of the 2nd card B is installed in expression in Fig. 9 (a), and in Fig. 9 (b), the state behind the 2nd card B has been installed in expression.

Shown in Fig. 8 (a), when inserting the 1st card A in housing 2, the 1st card A enters on the base portion 201 rearward.And if the leading section of the 1st card A arrives the position that presses down parts 206, then its partition wall 103 abuts to the abutting part 206b that presses down parts 206.Further the 1st card is inserted rearward in this state, shown in Fig. 8 (b), like that, be accompanied by this insertion, press down parts 206 and rotate, contact terminal 205 is depressed by its lower surface.At this moment, on contact terminal 204,,, flexibly be connected on the contact site 101 of the 1st card A so therefore be not depressed owing to there is not butt abutting part 206b.

In this case, because abutting part 206b has the bigger size of size of Width than the partition wall 103 of the 1st card A, so, can reliably contact terminal 205 be depressed by abutting part 206b.Therefore, can prevent the damage of contingent contact terminal 205 under situation about contact terminal 205 being depressed effectively by partition wall 103.

And, at the lower surface that presses down parts 206, be provided with the slot part 206d of a part of taking in contact terminal 205, can prevent that therefore the offset of contact terminal 205 from also depressing contact terminal 205 reliably.Moreover, owing to pressing down the inclined plane part 104 corresponding inclined plane part 206e of partition wall 103 that are provided with on the abutting part 206b of parts 206 with the 1st card A, therefore, can be reliably by the butt between inclined plane part 104 and the inclined plane part 206e and will press down parts 206 simply and depress.

On the other hand, shown in Fig. 9 (a), when inserting the 2nd card B in housing 2, the 2nd card B and the 1st card A similarly enter on the base portion 201 rearward.And even arrive under the situation of the position that presses down parts 206 at the leading section of the 2nd card B, owing on the position of corresponding its abutting part 206b partition wall 103 is not set, the partition wall 103 of the 2nd card B does not abut on the abutting part 206b.Therefore, further block the words that B inserts rearward in this state with the 2nd, shown in Fig. 9 (b), be accompanied by this insert action, pressing down under the state that parts 206 rotate a little, contact terminal 204 flexibly is connected on the contact site 101 of the 2nd card B, and contact terminal 205 flexibly is connected on the contact site 105 of the 2nd card B.

In this case, contact site 105 is set to along the roughly the same length of the 2nd card direction of insertion of B and contact site 101.As above-mentioned card connector in the past, under the situation that forms new contact site midway of existing contact site, because unwanted contact the between the existing contact site that card may block when inserting and the contact terminal that new contact site is used, so be necessary to the reply of this contact.But, as the connector in the present embodiment 1, contact site 105 is set to along under the situation of the roughly the same length of the 2nd card direction of insertion of B and contact site 101, because can avoid such contacting with the unwanted of contact terminal, so do not need this contact is tackled, can realize connector 1 by simpler structure.

The connector 1 of such a present embodiment, have the parts of pressing down 206, to depress with the contact site 105 corresponding contact terminals 205 of the 2nd card B, when carrying out the installation of the 1st card A, can abut to by the abutting part 206b that utilization presses down parts 206 on the partition wall 103 of the 1st card A and reliably contact terminal 205 be depressed, therefore can tackle the installation of the 2nd card B that in the zone of corresponding partition wall 103, is provided with new contact site 105, and, even under the situation of inserting the 1st card that this contact site 105 is not set, also can prevent the damage of the contact terminal 205 of new contact site 105 usefulness.

In addition, the invention is not restricted to above-mentioned execution mode, can produce various variations and enforcement.In the above-described embodiment, size shown in being not limited in the accompanying drawings or shape etc. can suitably change in the scope of performance effect of the present invention.In addition, as long as in the scope that does not exceed the object of the invention, can suitably change and implement.
