Abstract
The invention relates to a card connector. Specifically, the invention provides a card connector having a detection switch for detecting the insertion and pulling-out of a card. The card connector can perform scraping motion through the vertical movement of contact parts of a contact member forming the detection switch and can shorten the length of a card along an insertion length. When the card is detected by the detection switch detecting card insertion and pulling-out to be inserted, the top end of the card abuts on a cam part of a first contact member. If the insertion of the card continues, the card makes the cam part descend and then resides thereon. A first contact part descends and performs scraping motion on a second contact part. If the insertion of the card goes farther, the top end of the card passes through the upper part of the first contact part and abuts on the second contact part. The second contact part is separated from the first contact part with the further insertion of the card.

It is spaced apart with the first contact portion 41c of the first contact 41.Therefore, switch off state is maintained, maintenance detects the insertion of card
State.
In addition, under the inlay card conjunction state, maintain ground contactor 21 contact card 60 back side setting it is earthy
The state of pad 61, in addition, maintaining the state of the signal activation signal of contact 22~26 pad 62~66.
Additionally, the contact site 41d of the first contact 41 on constituting grounding component, under the chimerism of card 60,
As shown in Figure 11 (A), the length that there is the earthy pad 61 formed at the back side of card 60 is short without contacting the earthy pad
The situation of 61 contacts.In addition, as shown in Figure 11 (B), the length that also there is the earthy pad 61 formed at the back side of card 60 is long
And the contact site 41d of the first contact 41 contacts the situation of the earthy pad 61.
On the other hand, when card 60 is extracted from card insertion space 17, temporarily along card insertion side since inlay card conjunction state
Block 60 to pushing.Then, if hand is taken away from card 60, by the effect edge card discharge side of the spring members 54 of ejecting mechanism 50
Exerted a force to card 60, thus, it is possible to card 60 is extracted from card insertion space 17.During the card 60 takes out, the first contact 41
And second contact 42 carry out the action opposite with the insertion process of card 60.
That is, if temporarily pushing card 60 along card insertion direction since the inlay card conjunction state shown in Figure 10 and Figure 11, into
Card shown in Fig. 8 and Fig. 9 is given as security and cuts state.Now, the top of card 60 makes the second contact portion 42d of the second contact 42 to card
The depths side of direction of insertion pushes movement, and the second contact portion 42d is still spaced with the first contact portion 41c of the first contact 41
Open.Thus, the off-state of switch is maintained, maintenance detects the state of the insertion of card.
Then, if taking away hand from card 60 in the case where the card is given as security and cuts state, by the spring members 54 of ejecting mechanism 50
