See also Figure 1 and Figure 2, shielding casing 1 comprises base portion 10 and at least one sidepiece 11 straight down that is extended into respectively by base portion 10 each side downwards.The snap close piece 112 (in other embodiments, snap close piece 112 also can be that sidepiece 11 bottom levels form towards the bending of card receiving space) that sidepiece 11 is provided with opening 111 and outwards is bent into from sidepiece 11 bottom levels.Protrude out one along first shell fragment 12 that moves back the card direction from sidepiece 11 front ends, the free end of this first shell fragment 12 comprises that the lower end is ramped shaped extension downwards and extends into the blocking part 121 of vertical state to work the effect of keeping out downwards with the guidance part 120 and the upper end of playing guide function.Extend the back downwards from a certain position of base portion 10 lateral margins side direction and continue along moving back second shell fragment 13 that the card direction extends into, its free end extends to grounding leg 131 downwards.Base portion 10 upper edge plug-in card directions are provided with two pressure plates 14 that extend to the card receiving space, bury with the conducting terminal (not shown) and the edge of the electronic cards that guarantees to insert to take shape in terminal module 3 interior conducting terminals 31 (being detailed later) and closely contact.
Consult Figure 1 and Figure 2, insulating body 2 comprises upper and lower surperficial 20,21 and sidewall 22.Sidewall 22 is provided with projection 221.Upper surface 20 front portions of insulating body 2 comprise depressed part 23, accommodate the receiving space of electronic cards with formation.Lower surface 21 afterbodys comprise resettlement section 24, with host side submodule group 3.
See also Figure 1 and Figure 2, terminal module 3 comprises the plurality of conductive terminals 31 that is provided with welding ends 311, contact jaw 312.Two rows relatively arranged before and after conducting terminal 31 was, and edge buries and takes shape in terminal module 3.The contact jaw 312 of described conducting terminal 3 extends into the receiving space of electronic cards with the upper surface of terminal module 3.The lower surface of terminal module 3 comprises a pair of projection that plays the role of positioning 32.
See also Figure 1 and Figure 2, the tail end of printed circuit board (PCB) 4 is provided with weld part 41, a pair of accepting hole 42 and a pair of solder side 43.The dual-side of printed circuit board (PCB) 4 is respectively equipped with at least one fixed part 44.Fixed part 44 comprise a rectangle fixed part 441 and the long and narrow fixed part 442 that extends into along the plug-in card direction by rectangle fixed part 441 right sides (in other embodiment, towards the bending of card receiving space direction, long and narrow fixed part 442 forms for being extended along the plug-in card direction by rectangle fixed part 441 left sides snap close piece 112 from sidepiece 11 bottom levels).Rectangle fixed part 441 and long and narrow fixed part 442 are perforated design all, and the upper surface of printed circuit board (PCB) 4 is directly communicated with lower surface.Also comprise the conductive pad 47 that 45,46 and lengthwises of a pair of spacing hole extend on printed circuit board (PCB) 4 sides.The straight line that the straight line at first spacing hole 45, second spacing hole, 46 line places, conductive pad 47 lengthwises extend and the straight line at long and narrow fixed part 442 places are all point-blank or be parallel to each other, to guarantee that integral body that shielding casing 1 and insulating body 2 form is when the plug-in card direction is slided, when the part that sidepiece 11 extends insulating body 2 slips into long and narrow fixed part 442, the free end of first shell fragment 12 slips into second spacing hole 46 by first spacing hole 45, and the grounding leg 131 of second shell fragment 13 conductive pad 47 that never slips away from start to finish.
Consult Fig. 3 to shown in Figure 6, during installation, at first, the welding ends 311 of the conducting terminal 31 of terminal module 3 is welded on the printed circuit board (PCB) 4, projection 32 is contained in accepting hole 42, with positioning end submodule group 3; Secondly, opening 111 on the shielding casing 1 and projection 221 corresponding matching on the insulating body 2 are so that insulating body 2 firmly is contained in the shielding casing 1; At last, integral body with shielding casing 1 and insulating body 2 compositions, be assembled on the printed circuit board (PCB) 4 together from top to bottom, terminal module 3 is contained in the resettlement section 24 of insulating body 2, at this moment, the snap close piece 112 of shielding casing 1 just arrives by rectangle fixed part 441 and a little less than the lower surface of printed circuit board (PCB) 4, the grounding leg 131 that the free end of first shell fragment 12 is limited in first spacing hole, 45, the second shell fragments 13 is connected on the conductive pad 47; When promote the integral body that shielding casing 1 and insulating body 2 are formed after by forward direction along the plug-in card direction, the part that sidepiece 11 extends insulating body 2 is slipped in the long and narrow fixed part 442 by rectangle fixed part 441, the lower surface butt of the printed circuit board (PCB) 4 on snap close piece 112 and long and narrow fixed part 442 sides, so that the retain strength on the above-below direction to be provided, simultaneously, first shell fragment 12 is under the guiding of guidance part 120, slip into second spacing hole 46 by first spacing hole 45, and because the effect of keeping out of blocking part 121, stop first shell fragment 12 to skid off second spacing hole 46 in the other direction, so that the retain strength on the fore-and-aft direction to be provided.So far, whole electronic card coupler assembling finishes.Because conductive pad 47 has certain length, so in whole assembling process, the grounding leg 131 of second shell fragment 13 presses on the top of conductive pad 47 all the time.
In the present embodiment, first shell fragment 12 moves back the card direction from sidepiece 11 front end edges and protrudes out out, second shell fragment 13 extends the back downwards from base portion 10 lateral margin side direction and continues to form along moving back the extension of card direction, in fact, in other embodiments, moving back the card direction from sidepiece 11 front end edges protrudes out and forms, protrude out along the plug-in card direction from sidepiece 11 rear ends and to form, extending the back downwards from base portion 10 lateral margin side direction continues to form along moving back the extension of card direction, or extend the back downwards from base portion 10 lateral margin side direction and continue to form along the extension of plug-in card direction, in four kinds of modes, two shell fragments 12,13 extend in above-mentioned any one mode, all are disclosed content.
Electronic card coupler of the present invention, pass the fixing of promptly having realized electronic card coupler and printed circuit board (PCB) 4 in the process that continues to move in printed circuit board (PCB) 4 backs from top to bottom in the integral body of shielding casing 1 and insulating body 2 compositions along the plug-in card direction, compare with prior art, reduced operation (screw is fixed or welded), simplify processing procedure, saved cost.
