Embodiment

For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing embodiment of the present utility model is described.

For convenience of explanation, the lower-left side in accompanying drawing is expressed as to " front end " herein, the upper right side in accompanying drawing is expressed as to " end ".

Fig. 1 is the three-dimensional exploded view of the utility model card connector, and together with reference to shown in other each figure, as can be clearly seen from the figure, card connector of the present utility model is mainly by forming the insulating base 1 in plug-in card space and cover the housing 2 on insulating base 1, and the swingle 4 that is positioned at plug-in card space end coordinates one to be located at plug-in card space side and the push rod 3 of mutual interlock, and the pallet 5 that can carry electronic cards A forms, described electronic cards A can be inserted in described plug-in card space after tray 5 carryings, as shown in Figure 5, wherein the electronic cards A of the present embodiment is Mirco SIM.

On insulating base 1, be embedded with terminal group 11, this terminal group 11 is consisted of conducting terminal 111 and detection terminal 112, the electronic cards A or the detected electrons card A that with telecommunications, connect after inserting have or not grafting correct, insulating base 1 side edge is concaved with the groove 12 that can move forward and backward in default track for push rod 3, in groove 12 adjacent places, is convexly equipped with a projection 13.

Housing 2 can be covered in insulating base 1 to form plug-in card space, at least comprise a roof and the sidewall extending from roof two lateral bucklings, described sidewall mid portion is provided with the shell fragment 21 to the tilted extension in plug-in card space, described roof is provided with two spacing holes 22 using for stuck point 41 location on swingle 4, and described two spacing holes 22 are respectively relative to being located at the curved default track Shang Chu rotating of this stuck point 41 and Xia Chu (as Fig. 3).

Push rod 3 ends form uses the convergence part 31 for described swingle 4 interlocks, push rod 3 front ends are bent to form the withstanding part 32 of using for outside thimble 6 pushing and pressing, the shaft main body 30Xiang plug-in card space center direction of push rod 3 protrudes out an elastic arm 33, wherein described in the present embodiment, elastic arm 33 extends (as Fig. 2) from shaft main body 30 to push rod 3 front end withstanding part 32 direction bifurcateds, described elastic arm 33 also can extend (as Fig. 9) to push rod 3 end convergence part 31 direction bifurcateds from shaft main body 30, the outside bifurcated of elastic arm 33 protrudes out and forms a bend 331, these bend 331 both sides approach and are a pushing and pressing inclined-plane 332 to shaft main body 30 respectively, 30 formation of the bend 331 of described elastic arm 33 and shaft main body can be for the accommodating projection accommodation space 333 of projection 13 on insulating base 1.

Swingle 4, can be articulated on insulating base 1, and the plug-in card space end forming with respect to insulating base 1 and housing 2, swingle 4 one end can be embedded in the convergence part 31 of push rod 3 and form interlock with push rod 3, swingle 4 another ends also can be inserted in pallet 5 in plug-in card space interfere swing, and be provided with stuck point 41 in this end.

Pallet 5, as shown in Figure 4, has the accepting groove 52 that can accommodate electronic cards A, and is provided with in pallet 5 sides the draw-in groove 51 caving inward.

Fig. 6 is that the utility model is pulled out after housing 2, the view of tray 5 and card connector, road as we know from the figure, when inserting tray 5 (for ease of watching, on pallet 5, do not carry electronic cards A), tray 5 sides hold respectively, shell fragment 21 on compressing housing 2 and the elastic arm 33 on push rod 3, and make shell fragment 21 and elastic arm 33 that elastic deformation outwards occur, and bend 331 and the shell fragment 21 on housing 2 on elastic arm 33 are moved respectively gradually to the draw-in groove 51 of tray 5 dual-sides, finally fall within 5 liang of side bayonet slots of pallet 51 (as Fig. 7), and reach, inserted, stuck point 41 on swingle 4 falls within on housing 2 spacing holes 22 and locates at the same time, swingle 4 another ends are interlock push rod 3, now 332 inner sides, pushing and pressing inclined-plane on elastic arm 33 are subject to holding of insulating base 1 upper protruding block 13, cannot there is outside elastic deformation, cause the bend 331 on elastic arm 33 to be really limited to draw-in groove 51, thereby the pallet that can lock, be difficult for making pallet 5 come off by external force.

Fig. 8 is that the utility model card connector utilizes thimble to exit the view of pallet, when the withstanding part 32 on utilizing outside thimble 6 stamp push rods 3 exits pallet 5, on push rod 3 elastic arm 33 can be when push rod 3 be pressed into inside interlock simultaneously, pushing and pressing inclined-plane 332 on elastic arm 33 is because losing the active force of projection 13, and make bend 331 on elastic arm 33 be vulnerable to that pallet 5 is pushed and outwards deformation, and make the shell fragment 21 on this bend 331 and housing 2 depart from gradually 5 liang of side bayonet slots 51 of pallet, in order to exiting pallet 5, at the same time, swingle 4 has one end of stuck point 41 to eject pallet 5 to plug-in card spatial extrapolation, pallet 5 is discharged, stuck point 41 on last swingle 4 falls within housing 2 spacing hole and locates for 22 times.

Indulge the above, the utility model card connector, on insulating base and with respect to the projection at the default motion track of push rod place, while passing in can be in pallet to plug-in card space, the elastic arm that this projection is held on push rod makes it be difficult for elastic deformation occurs, and reaches the effect of a locking pallet, when pressing push rod and make pallet exit with interlock swingle, elastic arm on push rod departs from holding of projection simultaneously, in order to exiting pallet, therefore no matter in function, in assembling be all simple and easy compared with existing structure, facilitate.

The foregoing is only the schematic embodiment of the utility model, not in order to limit scope of the present utility model.Any those skilled in the art, is not departing from equivalent variations and the modification of doing under the prerequisite of design of the present utility model and principle, all should belong to the scope of the utility model protection.And it should be noted that, each part of the present utility model is not limited in above-mentioned overall applicability, each technical characterictic of describing in specification of the present utility model can select one to adopt separately or select the multinomial use that combines according to actual needs, therefore, the utility model has naturally been contained other combinations relevant with this case innovative point and specifically application.
