【Specific embodiment】

Embodiment：

Fig. 1-Fig. 5 is refer to, the present embodiment is tri-fold card holder structure, which includes metal shell 1, insertion metal shell 1 Kato 2 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 is provided between first draw-in groove plate 21 and the second draw-in groove plate 22.

1 end of metal shell is provided with the contact flat spring 11 supported by holding block 212.The present embodiment tri-fold card holder structure Also include that component 3 is ejected in detection, component 3 is ejected in detection to be included fixed block 31, the pin 32 being fixed on fixed block 31, be set in Rotating shaft 33, the pull bar 34 being fixedly connected with rotating shaft 33 on pin 32 and be fixed on 31 end of fixed block and with contact flat spring 11 Support 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 terminal module, processing procedure is greatly simplified, and product quality is high, and Low cost.Specifically,

2) by contact flat spring being arranged in metal shell end, and contact chip is set on detection ejection component, while In Kato, the end of the less first draw-in groove plate of length arranges holding block, supports contact flat spring by holding block and realizes that change connects The conducting state of tactile shell fragment and contact chip, it is achieved thereby that Kato insertion whether detection in place, the detection of Kato on position Sensitivity is higher, faster；

3) adopt split-type design, connection terminal be designed to into three independent terminal modules, respectively with the first draw-in groove, Two draw-in groove and the 3rd draw-in groove correspondence so that the processing procedure of connection terminal is simpler, product quality more can guarantee that.

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.
