The second side portion 33 is provided with a pair of elastic arms 331 for electrically contacting the third terminal 23 to realize the detecting function when the electronic card 2 is inserted.

[0019] The _th to the ninth to tenthth embodiment shows that the electronic card 200 is inserted in the electronic card connection 100. The electronic card 200 (such as an SD card or an MMC card) has a wide width and a narrow thickness. After entering the slot 14, the second card is located in the second guiding slot of the first side wall, and the electronic card 2GG enters After the human first guide #124, the driving portion 4" located in the first guiding groove 124 is driven to cause the foolproof portion 41 to move downward, and the anti-sliding portion 41 is moved downward to release the +-sliding member. 52 locks. Continue to insert the electronic card (4), the electronic card 2〇0 is in contact with the second playing portion 521 3 of the second sliding member 52, and then the second sliding member 52 is pushed backward to move the second sliding member 52 to drive the first sliding member 51 to the same direction. The movement until the first slider 51 is locked by the guide rod 55. The second sliding form, Α〇1〇ι, 11th page, and 33rd, the moving portion 52 is moved rearward, and the contact portion 224 of the second terminal is exposed to the upper side of the flat plate portion 5221. At the same time, the fourth guiding surface 5226 of the second sliding member 52 is inserted on the lower side of the guiding portion 2252 of the second terminal 22, and the lifting portion 2251 is lifted up by the pushing portion 5225, thereby driving the contact portion 224 upward. Lift up. The electronic card 200 can be electrically connected to the second terminal 22. When the card is retracted, the electronic card 200 can be pushed up again, the lock of the first slider 51 can be released, and the electronic card 200 can be withdrawn. After the second slider 52 is retracted, the contact portion 224 is again received. In the third receiving groove 5224. The actuating portion 225 is disposed on the front side of the contact portion 224, and the pushing portion 5225 acts on the actuating portion 225 to lift the contact portion 224 such that the force receiving point of the second terminal 22 is located at the contact portion 224 and the extending portion 223. Far away from the holding portion 221 to prevent the second terminal 22 from loosening, thereby achieving a stable connection. Moreover, the actuating portion 225 is provided with .-v.* - at the free end of the contact portion 224, so that the contact portion between the electronic card 2 and the contact portion 224 has a small frictional force, thereby providing a user with a better feel and improving market competition. force. In addition, the sliding plate 522 is provided with a guiding portion 522 2 and an abutting portion 5223 for guiding and carrying another type of electronic card insertion, and the contact portion 224 of the second terminal is accommodated when the sliding plate 522 is not pushed. The three receiving slots 5224 are provided to protect the contact portion 224 such that the entire sliding plate 522 occupies a small space in the slot, which facilitates miniaturization of the entire electronic card connector 100. [0020] In addition, if the electronic card 200 is directly pulled out when the card is withdrawn due to factors such as the user's operating habits, the first slider 51 is not driven, and the lock of the first slider 51 is not released by the guide rod 55. A sliding member 51 does not retract. At this time, the third spring 54 is provided to retract the second sliding member 52, and the elastic force of the third spring 54 is smaller than the friction of the second terminal 22 with the electronic card 2 The second slider 52 is not pushed when the electronic card 200 is inserted into the form number A0101, and the second slider 52 is separately retracted when the electronic card 200 is pulled out to prevent the cause. When the electronic card 200 is directly pulled out and the second slider 52 is not retracted, the electronic card 200 is inserted again across the second terminal, thereby effectively protecting the electronic card. [0021] When another type of electronic card (not shown, such as an MS card) having a narrow width and a thick thickness is inserted, the MS card is inserted into the slot 14 along the first and second guiding faces due to the size. The foolproof mechanism 4 is not driven because it does not enter the first guiding groove 124. After the MS card enters the trailing edge of the second sliding member 52, the guiding portion 5222 continues to penetrate and abuts the first blocking portion 511 and drives the first sliding member 51 to move backward until the guiding rod 55 locks the first sliding member 51, the MS card and the first A terminal 21 is in electrical contact. When the card is returned, it will be pushed again, and the M S card will exit the M...S: card. [0022] In summary, the creation complies with the new patent requirements, and the patent application is filed according to law. However, the foregoing is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and any equivalent modification or change made by a person familiar with the skill of the present invention in accordance with the spirit of the present invention should be It is covered by the following patent application.
