【Specific embodiment】

Embodiment：

Fig. 1-Fig. 5 is refer to, the present embodiment is the error-proof structure of three-in-one card seat, which includes metal shell 1, insertion metal The Kato 2 of housing 1 and some connection terminals being fixed on metal shell 1.

Kato 2 includes the first draw-in groove plate 21 being set up in parallel in the first direction and the second draw-in groove plate 22, the first draw-in groove First draw-in groove 211 similar with TF card contour shapes is provided with plate 21.Along vertical with first direction in second draw-in groove plate 22 The second draw-in groove 221 and the 3rd draw-in groove 222 that straight second direction is set up in parallel.The shape of the second draw-in groove 221 and the 3rd draw-in groove 222 It is similar with the contour shape of NANO-SIM cards.Second draw-in groove plate 22 length in a second direction is more than the first draw-in groove plate 21 Length in a second direction.First draw-in groove plate 21 end in a second direction arranges what oriented second direction extended out Holding block 212.Gap 23 is provided between first draw-in groove plate 21 and the second draw-in groove plate 22.

On metal shell 1, correspondence is provided with the bending part 12 being housed in gap 23 with 23 position of gap.12 edge of bending part Second party sets up and at least two, wherein near the end of metal shell 1 at one, another place is located at metal shell 1 Middle part.By the design of bending part 12, the direction of insertion of Kato 2 effectively can be guided, effectively can prevent to make With the unnecessary destruction caused in the case of unfamiliar so that the three-in-one card seat reliability of structure of the present embodiment is higher.

1 end of metal shell is provided with the contact flat spring 11 supported by holding block 212.The present embodiment three-in-one card seat it is anti- Slow-witted structure also include detection eject component 3, detection eject component 3 include fixed block 31, the pin 32 being fixed on fixed block 31, The rotating shaft 33 being set on pin 32, the pull bar 34 being fixedly connected with rotating shaft 33 and be fixed on 31 end of fixed block and with contact Shell fragment 11 supports the contact chip 35 of contact.

Connection terminal include with 211 corresponding the first terminal module 41 of the first draw-in groove, with the second draw-in groove 221 corresponding second Terminal module 42 and with 222 corresponding third terminal module 43 of the 3rd draw-in groove, the first terminal module 41, Second terminal module 42 And third terminal module 43 is independently arranged each other.

1 grounding connection of metal shell is arranged, and under normality (i.e. Kato 2 is not inserted in metal shell 1), component 3 is ejected in detection In contact chip 35 turned on metal shell 1 by the contact with contact flat spring 11；After in the insertion of Kato 2 metal shell 1, 212 jack-up contact flat spring 11 of holding block in Kato 2 so that contact flat spring 11 is separated with contact chip 35, so as to detection is ejected Component 3 is disconnected with metal shell 1, detects Kato so as to realize by detecting the conducting state for ejecting component 3 and metal shell 1 In place whether 2 insertion.

There is the present embodiment the beneficial effect of the deck of independent detection module to be：Draw-in groove is rationally distributed；Kato inserts position The detection sensitivity put is higher, faster；Using split type metal shell module, processing procedure is greatly simplified, and product quality is high, and Low cost.Specifically,

Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art, On the premise of design being created without departing from this utility model, can also make some deformations and improvement, these belong to practical New protection domain.
