Please further consult Fig. 6 to shown in Figure 8; With the operation principle of introducing electronic card coupler of the present invention in detail; Electronic card coupler of the present invention preferably is applicable to the roughly rectangular structure of SIM 60 (electronic card coupler of the present invention is equally applicable to other electronic cards identical with the SIM structure), and one jiao of this SIM is provided with breach 61.

At first, be illustrated in figure 6 as SIM 60 initial insertion states, this moment, SIM 60 was in the card pushed section 331 that pushes slide block 33 on the plug-in card direction and drive slide block 33 and on the plug-in card direction, move; Simultaneously; One side of said SIM 60 is to the U-shaped card contact site 46 away from receiving space 70 directions pushing and pressing fool proof parts 40; Force U-shaped card contact site 46 in the accommodation space 258 of the installation portion 25 of insulating body 20 to outer displacement; And then force first extension 43 to producing strain away from receiving space 70 directions; The shaft 41 that makes fool proof parts 40 is that rotate at the center with the fulcrum 254 of insulating body 20; According to lever principle, the limiting section 42 that said fool proof parts 40 are positioned at fulcrum 254 opposite sides will drive backstay 32 and move to receiving space 70 directions, finally force second positioning end 323 of backstay 32 to be displaced on first chute 341 that slides conduit 34 to receiving space 70 directions.During this time; Support piece 259 in the middle of the said UNICOM mouth 252 is positioned at the U-shaped space of U-shaped card contact site 46; When electronic cards is inserted and during extruding card contact site 46, said support piece 259 be used to support fool proof parts 40 U-shaped card contact site 46 in case U-shaped card contact site 46 be crushed and damage.

Subsequently; SIM 60 as shown in Figure 7 inserts state fully; Said SIM 60 is pushed in the receiving space 70 fully, at this moment, be positioned at card contact site 46 places of fool proof parts 40 owing to the breach 61 of 60 1 jiaos of SIMs; The card contact site 46 of fool proof parts 40 is thereupon in elastic recovery to the receiving space 70; At this moment, first extension, 43 same elastic recoverys and the limiting section 42 that drives fool proof parts 40 be to resetting away from receiving space 70 directions, thus second positioning end 323 that drives backstay 32 from the end of first chute 341 that slides conduit 34 in away from receiving space 70 direction landing to the second chutes 342.

At last; After SIM 60 pintle hook lock states as shown in Figure 8, said SIM 60 are pushed in the receiving space 70 fully, unclamp said SIM 60 after; Under the elastic-restoring force of elastic component 31; Slide block 33 moves along moving back the card direction, and at this moment, second positioning end 323 of backstay 32 is in the extremely heart-shaped groove 244 of second chute, 342 interior landings automatically and locate SIM 60 in receiving space 70; The card contact site 46 of said fool proof parts 40 still is positioned at breach 61 places of SIM 60, has so far accomplished the plug-in card process of SIM 60.Simultaneously, the breach 61 of 46 pairs of SIMs 60 of card contact site of said fool proof parts 40 has the effect of maintenance, can avoid SIM in receiving space 70, to break away from.

Please further consult shown in Figure 9; With the fool proof effect of introducing electronic card coupler of the present invention in detail; Promptly when SIM 60 is in wrong insertion state; The side of said SIM 60 is outwards pushed the card contact site 46 of fool proof parts 40 all the time; The card contact site 46 of fool proof parts 40 is in the state in the accommodation space 258 of the installation portion 25 that is squeezed into insulating body 20 all the time, and promptly said first extension 43 is in the state of strain all the time, and the limiting section 42 of said fool proof parts 40 is positioned at the position near receiving space 70 all the time; The limited mouth 420 that said backstay 32 receives limiting section 42 is positioned at first chute 341 all the time to the forces of receiving space 70 directions, and can't get in second chute 342; When illustrating said SIM 60 and inserting in the receiving space 70 fully with wrong way, the limiting section 42 that second positioning end 323 of backstay 32 receives fool proof parts 40 is in the end of first chute 341 to the pressure of receiving space 70 directions and can't gets in second chute 342; When unclamping SIM 60; The slide block 33 of trip mechanism 30 moves to moving back the card direction under the restoring force of elastic component 31; Because second positioning end 323 of backstay 32 receives the restriction of limiting section 42 can't get into second chute 342, at this moment, second positioning end 323 of backstay 32 can only slide first chute, 341 reciprocating motions of conduit 34; And can't get into pintle hook lock in the heart-shaped conduit 344; Promptly when the user adopts wrong mode to insert SIM 60, said SIM 60 can't be locked in the electronic card coupler, thereby reach the effect of fool proof.

Compared to prior art; Electronic card coupler of the present invention is provided with in the middle of UNICOM's mouth 252 of installation portion 25 and supports piece 259; When SIM 60 inserted electronic card coupler, SIM 60 is the card contact site 46 of extruding fool proof parts 40 outwards, and supports piece 259 to be positioned in the middle of the U-shaped card contact site 46; Card contact site 46 is played the effect of support, can prevent that the card contact site 46 of fool proof parts 40 from being flattened and damaging by SIM 60.
