To shown in Figure 8, during installation, at first, with conducting terminal 2 and the 10 one-body molded settings of insulating body 1 diapire, conducting terminal 2 contact sites 21 are positioned at the top of diapire 10 through holes 101 with reference to Fig. 3.Secondly, with the first detecting terminal 31, the second detecting terminal 32 and anti-writing in the accepting groove that terminal 4 is installed on insulating body 1 the first side wall 11 respectively.Then, the slide block 51 of trip mechanism 5 is installed in insulating body 1 second sidewall 12, wherein, at first the end with elastomer 52 cooperates fixing with the accepting hole 513 of slide block 51, and the other end of elastomer 52 cooperates fixing with the post 131 that protrudes out of insulating body 1.Subsequently, first kink 532 of connecting rod 53 is inserted in the location hole 123 of second sidewall 12, and second kink 533 is inserted in the chute 511 of slide blocks 51, and can moving forward and backward and chute 511 in, move with slide block 51.Then, the holding part 542 of shell fragment 54 interlocked with slide block 51 holding holes 512 hold, at this moment, the base portion 541 of shell fragment 54 is positioned between the medial surface (not label) of second sidewall, 12 sides 121 and slide block 51, the insertion section 543 of shell fragment 54 is positioned at slide block 51 recesses 515, and the support division 544 of shell fragment 54 contacts with slide block 51 medial surfaces.At last, shielding casing 6 is installed on the insulating body 1, the lug 612 of shielding casing 6 inserts in the support slot 132 of insulating body 1 rear wall 13, and the breach 621 of shielding casing 6 sides 62 and the hangnail 124 on insulating body 1 the first side wall 11 and second sidewall 12 interlock and hold.The electronic card coupler 100 that assembles is installed on the circuit board (not shown), with the conducting portion 622 of shielding casing 6, conducting terminal 2, detecting terminal 3 and anti-ly write terminal 4 and weld mutually with circuit board respectively.

With reference to Fig. 6 and shown in Figure 8, during use, the electronic cards 7 that will have recess 70 is inserted in the electronic card coupler 100, in the use, electronic cards 7 can not contact with the base portion 541 or the support division 544 of shell fragment 54, and can push the protuberance 546 of shell fragment 54 insertion sections 543, thereby force the horizontal part 545 of shell fragment 54 and protuberance 546 to move laterally, at this moment, shell fragment 54 base portions 541 and support division 544 are resisted against the medial surface of slide block 51, between slide block 51 and the shell fragment 54 interaction force are arranged, thereby, during plug electronic cards 7, shell fragment 54 is outwards pushed by electronic cards 7, simultaneously, electronic cards 7 also is subjected to a reaction force, trip mechanism 5 can provide enough big contact engaging and separating force, the convenience that order plug electronic cards 7 becomes, and electronic cards 7 can slippage.When electronic cards 7 contacts the rear end of trip mechanisms 5 slide blocks 51, electronic cards 7 recesses 70 are positioned at a side of the protuberance 546 of shell fragment 54 insertion sections 543, the base portion 541 of shell fragment 54 restores to the original state and level moves inward, the protuberance 546 of shell fragment 54 insertion sections 543 also level moves inward and inserts in the recess 70 of electronic cards 7, thereby can prevent that electronic cards 7 is former thereby the generation of problem such as drop out in the electronic card coupler 100 because of vibrations etc.Further ejection electronic cards 7, trip mechanism 5 slide blocks 51 are subjected to ejection and move along the plug-in card direction, elastomer 52 is compressed, when holding front position (not label) when sliding in the chute 511 of second kink 533 at slide block 51 of described connecting rod 53 to chute 511, thereby trip mechanism 5 can not be pushed, and at this moment, shielding casing 6 fastening pieces 613 are pressed on the electronic cards 7, shielding casing 6 buttons are held the connecting rod 53 that sheet 614 compresses trip mechanism 5, can prevent that connecting rod 53 from skidding off in chute 511.So electronic cards 7 is stable to be contained in the receiving space of electronic card coupler 100, the contact site 21 of the conductive path of electronic cards 7 (not shown) contact conducting terminal 2, and detecting terminal 3, anti-ly write terminal 4 and also be subjected to the extruding of electronic cards 7 and realize corresponding function.

When taking out electronic cards 7, once more along plug-in card direction ejection electronic cards 7, second kink 533 of connecting rod 53 breaks away from the front position of slide block 51 chutes 511, and elastomer 52 discharges elastic force, force trip mechanism 5 to move along pulling out the card direction, when elastomer 52 restores to the original state fully, connecting rod 53 second kinks 533 move to the back position (not label) of slide block 51 chutes 511, at this moment, slide block 51 is got back to original position, exert oneself a little, the protuberance 546 of shell fragment 54 insertion sections 543 is skidded off in electronic cards 7 recesses 70, the mutual button that can remove between electronic cards 7 recesses 70 and shell fragment 54 insertion sections 543 is held and smoothly electronic cards 7 is extracted in receiving space.

Really, described shell fragment 54 also can with slide block 51 one-body molded manufacturings.Compared with prior art, the shell fragment 54 of the trip mechanism 5 of the utility model electronic card coupler 100 is provided with insertion section 543 and slopes inwardly and extends the certain flexible base portion 541 that has that forms, can realize the pintle hook lock purpose, and need not to be provided with separately in addition parts that provide the made shell fragment 54 of elastic force to move horizontally, simplified the structure of trip mechanism 5, reduce the operation of making and assembling trip mechanism 5, saved production cost.In addition, during plug electronic cards 7, shell fragment 54 is pushed by electronic cards 7 and outwards moves, the base portion 541 of shell fragment 54 and support division 544 butt slide blocks 51, thereby trip mechanism 5 can provide enough big contact engaging and separating force, and convenience and electronic cards 7 that order plug electronic cards 7 becomes can slippages.
