Refer to accompanying drawing.Notice, appended graphic the illustrated structure of this specification, ratio, size etc., all contents in order to coordinate specification to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this specification, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
As shown in Figure 1, the utility model provides a kind of terminal structure 100, and this terminal structure 100 is electrically connected between SIM card and pcb board, and described terminal structure 100 at least comprises: plastic cement matrix 1 and terminal 2.
On described plastic cement matrix 1, be provided with the cell body 11 of a hollow out.As shown in Figure 1, described cell body 11 can adaptation hold terminal 2.Particularly, the cell body 11 of hollow out is set in the centre position of described plastic cement matrix 1, this cell body 11 penetrates upper surface and the lower surface of described plastic cement matrix 1 from vertical direction, and the cell body 11 of hollow out directly exposes the surface of pcb board.The shape of described cell body 11 is formed by the mould of described plastic cement matrix 1 in the process of plastic cement matrix 1 described in injection moulding.
Described terminal 2 comprises the first fixed part 21, the second fixed part 22, the first cantilever 23, the second cantilever 24 and termination contact portion 25;
Described the first fixed part 21 is separately fixed on described cell body 11 both sides sidewalls with wherein one end of the second fixed part 22, the other end is all connected with termination contact portion 25; Described termination contact portion 25 is higher than described plastic cement matrix 1 upper surface; One end of described the first cantilever 23 and the second cantilever 24 is connected with described termination contact portion 25 respectively, the other end is the free terminal 231,241 lower than described plastic cement matrix 1 upper surface.
As a kind of preferred structure of the present utility model, on the two side of described cell body 11, be provided with protuberance 111 and recess 112, described the first fixed part 21 and the second fixed part 22 are fixed on protuberance 111 corresponding to cell body 11 both sides, and the free terminal 231,241 of described the first cantilever 23 and the second cantilever 24 is arranged in recess 112 corresponding to cell body 11 both sides.
It should be noted that, the lower surface of free terminal 231, the 241 a little higher than described plastic cement matrixes 1 of described the first cantilever 23 and the second cantilever 24, so that while being subject to downward active force, there is the space of compressive deformation in described termination contact portion 25.In addition, free terminal 231,241 can not be higher than the upper surface of described plastic cement matrix 1, is hooked to terminal 2 when avoiding foreign components to push or to extract, and terminal 2 is destroyed.
Also it should be noted that, described termination contact portion 25 need to be higher than the upper surface of described plastic cement matrix 1, and preferably, described termination contact portion 25 is higher than the upper surface 0.20～0.65mm of described plastic cement matrix 1.
Further, described termination contact portion 25 can not be the wedge angle of bending, can be spheroid, can ensure that like this termination contact portion 25 is not easy to scratch SIM card.The bare spot of described SIM card is that line contacts or face contact with the contact form of termination contact portion 25.Described SIM card can be Nano SIM card, can be also Micro SIM card, does not limit at this.
Further, described terminal 2 also comprises and is embedded at the inner and embedded component that is connected with described the first fixed part 21, the second fixed part 22 of described plastic cement matrix 1 and is connected with described embedded component and stretches out the weld part 26 of described plastic cement matrix 1.By terminal 2, the pcb board in mobile phone adapter and mobile phone can be electrically connected.Preferably, described weld part 26 is welded on the upper surface of described pcb board.Because described insertion part is embedded in plastic cement matrix 1, in figure, cannot mark.
Described terminal 2 adopts sheet metal to make, and can be fixed on described plastic cement matrix 1 by in-mould injection technique.
Be illustrated in figure 2 the edge frame 3 of SIM adapter, Fig. 3 is the drawer type Kato dish 4 for carrying SIM card; Fig. 5 is that external structure inserts from first direction, second direction and the third direction of terminal structure the schematic diagram of extracting respectively.When inserting while extracting not carrying the SIM adapter of SIM card or drawer type Kato dish, termination contact portion 25 is because the active force of SIM adapter and drawer type Kato dish moves downward, until move in the cell body 11 of described plastic cement matrix 1, can avoid SIM adapter and drawer type card Pallet side frame 5, in the process promoting, terminal is caused to damage, be illustrated in figure 5 SIM adapter or drawer type card Pallet side frame 5 and insert along first direction the schematic diagram that termination contact portion 25 moves downward while extracting; Be illustrated in figure 6 SIM adapter or drawer type card Pallet side frame 5 and insert along second direction the schematic diagram that termination contact portion 25 moves downward while extracting.
Please refer to accompanying drawing 7 again, for SIM card is from third direction inserted terminals structure, can see, in the time of SIM card inserted terminals, the pressure that termination contact portion 25 is subject to SIM card down moves, and finally moves to below plastic cement matrix, can avoid terminal to be hooked by SIM card and destroyed.
In sum, the utility model provides a kind of terminal structure, is electrically connected between SIM card and pcb board, and described terminal structure at least comprises: plastic cement matrix and at least one terminal; On described plastic cement matrix, be provided with the cell body of a hollow out; Described terminal comprises the first fixed part, the second fixed part, the first cantilever, the second cantilever and termination contact portion; Wherein one end of described the first fixed part and the second fixed part is separately fixed on the sidewall of described cell body both sides, the other end is all connected with termination contact portion; Described termination contact portion is higher than described plastic cement body upper surface; One end of described the first cantilever and the second cantilever is connected with described termination contact portion respectively, the other end is the free terminal lower than described plastic cement body upper surface.The terminal structure that the utility model provides, SIM adapter is in the time that insertion is extracted, and termination contact portion moves downward under the effect of frame, thereby prevents from hooking terminal in process that SIM adapter extracts in insertion and destroy terminal structure, the useful life of improving terminal.
