Consult Fig. 6, Fig. 7, each weldment 7 has one second connecting portion 71 and a welding board 72, second connecting portion 71 be one by plate around the latch closure that constitutes, be engaged in order to socket on the Extendible flake 521 of first connecting portion 52, welding board 72 is then by the outside horizontal-extending of the root edge of second connecting portion 71, and each weldment 7 be provided with one by second connecting portion 71 extend to the welding board 72 blocked hole 73, stuck point 522 for first connecting portion 52 is inserted, weldment 7 can be moved up and down with respect to this Extendible flake 521, avoid weldment 7 to break away from first connecting portion 52 because of gravity down drops simultaneously.

Consult Fig. 7, Fig. 8, even cover plate 51 is stressed generation plate bending deformation in carrying or assembling process, and the Extendible flake 521 that makes its front side the right and left produces and is uneven (promptly one high and one low) and can't touch circuit board 300 simultaneously the time, up and down property by two weldments 7, make the welding board 72 that is connected with Extendible flake 521 can touch on the circuit board 300 equally, and needn't be again via people's secondary adjustment of working, correct the action of cover plate 51 evenness, in addition, when tin cream is coated on the welding board 72 and when making solder joint 303 solid weldings on itself and the circuit board 300, utilize the hair crack effect of blocked hole 73, tin cream is infiltrated in the blocked hole 73 and the Extendible flake of solid welding simultaneously 521 and second connecting portion 71, and weldment 7 can't be moved up and down with respect to first connecting portion 52 again, after avoiding electric connector 3 welderings to be located on the circuit board 300, shielding cover body 5 still can produce the phenomenon of rocking.

Later consult Fig. 4, Fig. 5, except that above-mentioned member, the utility model electronic card coupler 3 more comprises an anti-read-write switch 47 and the sense switch 48 for SD card 302 usefulness.Anti-read-write switch 47 comprises one first shell fragment 471 and one second shell fragment 472, first shell fragment 471 is the first side wall 42a that are located at insulation shell 4, front and back extension again after second shell fragment 472 is then down bent by cover plate 51 left plate edge rears, and front end is slightly V-shaped and constitute one first prominent top 472a toward inner bending, the first side wall opening 422 by the first side wall 42a protrudes in the holding part 44, and corresponding with first shell fragment, 471 front ends.And this sense switch 48 comprises one the 3rd shell fragment 481 and one the 4th shell fragment 482, the 3rd shell fragment 481 is located at insulation shell 4 second sidewall 42b, front and back extension again after the 4th shell fragment 482 is then down bent by cover plate 51 right plate edge rears, and front end is slightly V-shaped and constitute one second prominent top 482a toward inner bending, one second sidewall opening 423 by the second sidewall 42b protrudes in the holding part 44, and corresponding with the 4th shell fragment 481 front ends.As for the action principle of these switches 47,48 has been the technology of the known and widespread usage of electronic card coupler dealer, so no longer giving given unnecessary details more.

Consult Fig. 9, Figure 10, it is second preferred embodiment of the utility model electronic card coupler, the electronic card coupler 3 ' of present embodiment and the first preferred embodiment difference are: first preferred embodiment is that circuit board 300 tops are located in electronic card coupler 3 welderings, present embodiment then is that circuit board 300 belows are located in electronic card coupler 3 ' weldering, so, two Extendible flakes 521 of first connecting portion 52 are up to bend extension by the left and right sides plate edge that cover plate 51 is close to the leading edge places, stuck point 522 then is arranged on each Extendible flake 521 lateral surface equally, and the structure of each weldment 7 is then identical with first preferred embodiment.

And be interfixing of reinforced insulation housing 4 and shielding cover body 5, shielding cover body 5 also has two and down bends second Extendible flake 55 that backward extends again by limit, the cover plate 51 leading edge left and right sides respectively, and the caulking groove 421 ' of insulation shell 4 two side 42a, 42b leading edge does not down run through, and plants fixing for these two second Extendible flakes 55 respectively.

In sum, the utility model electronic card coupler 3,3 ' utilizes two weldments 7 to be placed on the Extendible flake 521 of cover plate 51 left and right sides, even make the shielding cover body 5 of electronic card coupler 3 produce the plate bending deformation because of being squeezed, cause its left and right sides Extendible flake 521 to produce one high and one low and can't contact welding simultaneously with circuit board 300, also can be by the up and down adjustment of two weldments 7, and can corresponding touch on the solder joint 303 of circuit board 300 equally, and needn't be in the process of production line, again manually shielding cover body 5 is corrected leveling work, not only save manpower, and can improve the production efficiency on the production line.

But, the above only is preferred embodiment of the present utility model, when not limiting claim scope of the present utility model with this, promptly the simple equivalent of doing according to the utility model claim and description generally changes and modifies, and all still belongs in the claim scope of the present utility model.
