Embodiment
Below will combine accompanying drawing, the embodiment and the embodiment of the utility model specified, described specific embodiment in order to explain the utility model, is not the embodiment that is used to limit the utility model only.
A kind of double SIM card connector of the utility model, one of its embodiment, as shown in Figure 1, be arranged on the pcb board 110, comprise two card decks 120 and be embedded in a plurality of metal clipss in two card decks 120; Metal clips comprises elastic contact part 123 (or 124) and the weld part 126 (or 128) that one connects, and metal clips can be processed by the hardware punching press; The elastic contact part 123 (or 124) of metal clips is used for contacting respectively and electrically connecting the surface metal wiring board (being that Fig. 1 is positioned at the position that the last two row's square holes of SIM 130 (with 140) are illustrated) of SIM 130 (and/or 140); The weld part 126 (or 128) of metal clips be used for pcb board 110 on corresponding pad soldering be connected, constitute the electric connection structure of SIM 130 (and/or 140) and pcb board 110 with this; Wherein, an area is set and wants the first little vestibule 111 on pcb board 110 than SIM 130 (or 140); Two card decks 120 are inlaid in first vestibule 111, but SIM 130 (or 140) can not be inlaid in first vestibule 111; Simultaneously; As shown in Figure 3; The metal clips contact SIM 130 that is connected with weld part 126 one with elastic contact part 123 is an example; In two card decks 120, also be provided with second vestibule 121 of a plurality of adaptive metal clips elastic contact parts 123, it is movable at second vestibule 121 to be used for elastic contact part 123; In addition, the top of metal clips elastic contact part 123 or end face must exceed the surface of pcb board 110 upsides, to touch the surface metal wiring board that is positioned at pcb board 110 upside SIMs 130.
Different is; For the metal clips contact SIM 140 that elastic contact part 124 is connected with weld part 128 one; The metal clips that elastic contact part 124 is connected with weld part 128 one; The direction of the metal clips that is connected with weld part 126 one with elastic contact part 123 is just opposite, and the top of metal clips elastic contact part 124 or end face must exceed the surface of pcb board 110 downsides, to touch the surface metal wiring board that is positioned at pcb board 110 downside SIMs 140.
In the preferred implementation of the utility model double SIM card connector; As shown in Figure 1; First vestibule 111 is the vestibule of a complete closed preferably, can make full use of first vestibule 111 pcb board 110 wooden partitions all around thus, can effectively avoid the impact that in the mobile phone falling process sim card connector is caused; Make sim card connector more firm, prevent that devices such as SIM from dropping.
Be preferably, as shown in Figure 1, can also increase a side muscle 122 in the both sides of two card decks 120 respectively, to improve the structural strength of two card deck 120 self; Accordingly, the shape of first vestibule 111 is also wanted corresponding change on the pcb board, blocks deck 120 setting-ins wherein with the two of adaptive band side muscle 122.
Concrete, as shown in Figure 1, second vestibule, 121 preferred length directions along two card decks 120 are two rows and are provided with, and metal clips is provided with in two card decks 120 along the length direction of SIM 130 (or 140) side by side at interval; Further dwindling the areas of two card decks 120, thereby reduce the area that takies pcb board 110.Wherein, the metal clips of the metal clips of an adaptive SIM 130 and adaptive another SIM 140 is crisscross arranged.
Be preferably, as shown in Figure 2, the shape of the elastic contact part 123 (or 124) of metal clips can be inverted V-shape; Can decompose pressure along its length thus, to avoid the metal clips deformed damaged to cause and loose contact to occur with SIM.Because two card decks 120 need adaptive two SIM cards 130 (with 140); Guarantee to reduce to take the area of pcb board 110 again as far as possible; So, be positioned under the almost completely overlapping situation of pcb board 110 both sides, two SIM cards 130 (with 140), just make two card decks 120 have width smaller; Also make the width of metal clips become narrower thus, and narrower metal clips elastic contact part 123 (or 124) is difficult to form complete hemispherical or contact that taper is round table-like through the mode that stretches.In addition, the second narrower vestibule 121 of width also can be avoided wherein metal clips to receive from the pressure of side and causes deformed damaged on two card decks 120.
Further, as shown in Figure 2, the last plane of inverted V-shape elastic contact part 123 (or 124) root and the upper surface of weld part 126 (or 128) flush.Because the lower plane of metal clips weld part 126 (or 128) overlap joint is on the same surface of pcb board of first vestibule, 111 peripheries; Contact with SIM; And the thickness of weld part 126 (or 128) is equal to the thickness of elastic contact part 123 (or 124); So the last plane of elastic contact part 123 (or 124) bottom can be considered the surface of assembling back SIM surface metal wiring board, the elastic force that has produced when the inverted v-shaped height of inverted V-shape elastic contact part 123 (or 124) has determined the metal clips compressive deformation thus; The position on plane is too high on inverted V-shape elastic contact part 123 (or 124) bottom; With the deflection that increases metal clips; Cause metal clips to follow the string easily even rupture; And the position on plane is low excessively on inverted V-shape elastic contact part 123 bottoms, also causes easily and the loose contact of SIM surface metal wiring board.
Further, as shown in Figure 2, the elastic contact part 123 (or 124) of metal clips can be connected with weld part 126 (or 128) one through a junction 129; Said connecting portion 129 can be shapes such as U font or W font.To increase and two bond strengths of blocking decks.
Be preferably, as shown in Figure 3, the metal clips contact SIM 130 that is connected with weld part 126 one with elastic contact part 123 is an example, is horizontally arranged with draw-in groove 125 at the sidewall of second vestibule 121; The head 127 of inverted V-shape elastic contact part 123 extends to forward in this draw-in groove 125 on the metal clips, and movable setting.Just because of the front end of metal clips is stuck in two card decks 120 and retractable, avoided the front end perk of metal clips thus and damaged, prolonged the useful life of double SIM card connector.
Based on above-mentioned double SIM card connector, the utility model has also proposed a kind of pcb board assembly, comprises pcb board and is arranged on the double SIM card connector on the pcb board; Wherein: said double SIM card connector is like each described double SIM card connector among the above-mentioned embodiment.
Based on above-mentioned double SIM card connector, the utility model has also proposed a kind of mobile phone, comprises shell and inner pcb board thereof, and pcb board is provided with the double SIM card connector; Wherein: said double SIM card connector is like each described double SIM card connector among the above-mentioned embodiment.
Compare with pcb board assembly and double SIM card connector thereof with mobile phone of the prior art; A kind of mobile phone that the utility model provided and pcb board assembly and double SIM card connector thereof; Because two card decks are inlaid on the pcb board than in the first little vestibule of SIM; And metal clips is inlaid in elastic contact parts in two card decks and fits in second vestibule of two card decks movablely, and makes full use of the elastic contact part that metal clips exceeds the pcb board both side surface and contacts two SIMs respectively, has dwindled the area of two card decks; Thereby when saving two card deck thickness, reduced the area that takies mainboard, satisfied the designing requirement of extra small ultra thin handset.
Should be understood that; The preferred embodiment that the above is merely the utility model is not sufficient to limit the technical scheme of the utility model, concerning those of ordinary skills; Within the spirit and principle of the utility model; Can increase and decrease according to above-mentioned explanation, replacement, conversion or improvement, and all these increases and decreases, replacement, conversion or improve after technical scheme, all should belong to the protection range of the utility model accompanying claims.
