Then, as shown in Figure 7, when card 1 the front-end edge 1a screw down step 31e of portion, operation strip 311 deflection deformations.Then, leading section 31b is pressed to than blocks 1 face more by following, and strains take place operation strip 311.Also have, in this stage, the front-end edge 1a of card 1 does not contact leading section 31d (with reference to Figure 10).Here, because operation strip 311 downward direction deflections, the leading section 31d of contact plate 31 descends, the displacement of contact 313 downward directions.At this moment, though contact 313 is configured in equal height with contact 323, owing to have horizontal gap, so become the relative position relation that is difficult to be in contact with one another.Therefore, sense switch 3 is not for detecting the off-state of card 1.
Then, as shown in Figure 8, when blocking 1 when further being inserted in the recess 21, the bight 1b of card 1 pushes leading section 31b, makes operation strip 312 deflection deformations.In addition, 1 bight 1b pushes leading section 31d by card, makes operation strip 312 deflection deformations.In this stage, because the leading section 31d of operation strip 312 is subjected to displacement in the horizontal, so contact 313 also is subjected to displacement in the horizontal.
Like this, contact 313 is through blocking 1 insertion and receive the displacement of downward direction and to horizontal displacement, thereby contacts with contact 323.And, through contact plate 31 with contacted by contact plate 32, sense switch 3 becomes status of electrically connecting (with reference to Figure 11).In addition, when extracting card 1, contact plate 31 returns to the origin-location, and contact 313 leaves from contact 323, so contact plate 31 and become the disconnected state of TURP by contact plate 32.Like this, just detected and blocked 1 have or not.
Connector 10 of the present invention, even act on the inertia force of an oriented direction, this inertia force to a direction is produced by vibration that makes the displacement of leading section 31b downward direction or impact, contact 313 can not contact with contact 323.In addition, even effect has the inertia force that leading section 31d is shifted in the horizontal, contact 313 can not contact with contact 323.Only have and make contact 313 downward directions and when the strong inertia force of strain takes place direction simultaneously to the right, just can contact with contact 323 in effect.Therefore, connector 10 of the present invention can suppress by the erroneous detection of vibrating or impacting the card that is caused.
In addition, in connector 10 of the present invention, because contact 323 inclinations, so contact 313 and its sliding contact.Can carry out so-called self-cleaning (with reference to Fig. 5).
In connector 10 of the present invention, one in a plurality of contacts 4 can be also used as contact plate 31.Through reducing the requirement of contact 4 like this, can help the reduction of manufacturing cost.
