Therefore, be necessary to provide the new electronic card coupler and the fit system of printed circuit board (PCB),, thereby improve product competitiveness with the utilance of raising printed circuit board (PCB).

[summary of the invention]

The object of the present invention is to provide a kind of electronic card connector assembly that uses printed circuit board (PCB) of saving.

The technical scheme that realizes purpose of the present invention is: a kind of electronic card connector assembly, it comprises the plastic casing with electronic cards receiving space, cover the shielding casing on the plastic casing, insulating body, be housed in plurality of conductive terminals in the above-mentioned insulating body and the printed circuit board (PCB) that is assembled into above-mentioned plastic casing, the insulating body that contains conducting terminal is placed on the printed circuit board (PCB), be assembled into plastic casing with printed circuit board (PCB), wherein, described plastic casing is provided with a breach that connects with the electronic cards receiving space, conducting terminal partly sees through described breach and extends into the electronic cards receiving space, and printed circuit board width is less than the plastic casing width.

Compared with prior art, the present invention has following beneficial effect: the printed circuit board width of electronic card connector assembly of the present invention is less than the plastic casing width, thus minimizing printed circuit board (PCB) usable floor area, and then reduce the production manufacturing cost.

[embodiment]

Please refer to Fig. 1 to shown in Figure 2, electronic card connector assembly 100 of the present invention comprises shielding casing 1, plastic casing 2, insulating body 3, conducting terminal 4, printed circuit board (PCB) 5 and flexible switching circuit board 6.

Shielding casing 1 covers on the plastic casing 2, shielding casing 1 and plastic casing 2 both sides be provided with the holding part (not label) that can fasten mutually with by holding part (not label).Form electronic cards receiving space 21 between shielding casing 1 after the assembling and the plastic casing 2.Shielding casing has a rectangular body portion 11, and the main part two ends are respectively front end 12 and rear end 13, and the main part 11 of close rear end 13 is provided with a pair of shell fragment 110.Shell fragment 110 has free end (not label) to electronic cards receiving space 21 intrinsic deflections.Front end 12 is the electronics card insert opening of electronic card coupler 100.

Please refer to shown in Figure 2, conducting terminal 4 is contained in insulating body 3, conducting terminal 4 comprises the first conducting terminal group 41 and the second conducting terminal group 42, the first conducting terminal group 41 includes weld part 410, elastic portion 411 and connects the connecting portion (not label) of weld part 410 and elastic portion 411, weld part 410 extends out from body 3 one end faces that insulate, elastic portion 411 is from body 3 upper surfaces that insulate extensions that be inclined upwardly, and elastic portion 411 is arranged setting for being two.The second conducting terminal group 42 is positioned at the first conducting terminal group, 41 rear ends, the second conducting terminal group 42 is a pair of detecting terminal, be used to detect the electronic cards and the first conducting terminal group 41 and whether be positioned at correctly and connect, guarantee that with this electronic cards and 41 of first conducting terminals electrically conduct.

The insulating body 3 that contains conducting terminal 4 is placed on the printed circuit board (PCB) 5, and the weld part 410 of the first conducting terminal group 41 and the weld part of the second conducting terminal group 42 (not label) all are welded on the corresponding conductive path of printed circuit board (PCB) 5.Printed circuit board (PCB) 5 is provided with some perforation 51, and perforation 51 is distributed in around the insulating body 3.Flexible switching circuit board 6 also is welded on the printed circuit board (PCB) 5, is used for electronic card coupler 100 and other electric equipment are electrically conducted.

Please refer to Fig. 2 to shown in Figure 3, plastic casing 2 has bottom surface 22, offers a breach 210 on the bottom surface 22, and breach 210 connects with electronic cards receiving space 21.Have carrier 220 around the breach 210, carrier 220 is stepped with bottom surface 22 formation, and carrier 22 is provided with the column 221 of some and above-mentioned perforation 51 corresponding settings.The printed circuit board (PCB) 5 that is provided with insulating body 3 is by plastic casing 2 upwards assemblings of bottom surface 22, and printed circuit board (PCB) 5 is contained in the aforementioned carrier 220, makes the perforation 51 of printed circuit board (PCB) 5 cooperate with the column 221 of carrier 220.Assembling is finished rear column 221 and is cooperated with hot melting way between 51 with perforation, and after the cooperation, printed circuit board (PCB) 5 and plastic casing 2 are assembled into one behind the hot melt.The breach 210 that the conducting terminal 4 that is contained in insulating body 3 sees through bottom surface 22 extends in the electronic cards receiving space 21.The electronic cards of inserting electronic cards receiving space 21 promptly can electrically conduct with the first conducting terminal group 41, whether the second conducting terminal group 42 is used to detect electronic cards inserts in the electronic cards receiving space 21 fully, judges with this whether the electronic cards and the first conducting terminal group 41 reach stable the butt joint.
