Detailed Embodiments
[0020] The utility model will be further described below in conjunction with the accompanying drawings.
[0021] As shown in Figure 1-6, a clamshell SM card holder includes a cover 1, a plastic body 2 and a contact PIN pin 3. The end of the cover 1 is connected to the plastic body 2 The ends are hinged, and the plastic body 2 includes a bottom plate 4 and sides 5 located on both sides of the bottom plate 4. Eight contact PIN feet 3 are provided on the bottom plate 4, and a wavy pattern is provided on the outer wall in the middle of each side 5. The first positioning groove 6 and the second positioning groove 7 are connected in a shape, and the front end of one of the sides 5 is recessed inward to form a card body 12. The cover body 1 includes a top plate 9 and a snap plate 10 located on both sides of the top plate 9. A positioning buckle 8 that can extend into the positioning groove on the corresponding side for positioning is formed in the inwardly recessed middle of each engaging plate 10. The connection position between the top plate 9 and the engaging plate 10 above the positioning buckle 8 is set to a hollow 19, which is hollow. 19 facilitates the matching of the positioning buckle 8 and the positioning groove.
[0022] A hook 11 extends downward from the bottom of the front end of the top plate 9. The hook 11 is opposite to the engaging plate 10 on one side to form a clamping cavity 20. Between the hook 11 and the clamping plate 10, a clamping cavity 20 is formed. Protrusions are respectively provided on the inner surfaces of the plywood 10 at opposite positions. The card body 12 can extend into the clamping cavity 20 . The clamping cavity 20 contacts and clamps the outer surface of the card body 12 through the corresponding protrusions.
[0023] A first switch PIN pin 13 and a second switch PIN pin 14 that can contact each other are provided on the front end of the other side 5 corresponding to the side of the card body 12. On the second switch The tail end of the PIN pin 14 is provided with a cantilever 15 extending out of the outer wall of the other side 5. The inner wall of the engaging plate 10 on the opposite side can contact and squeeze the cantilever 15, so that the first switch PIN pin 13 and the second switch PIN pin 14 are in contact with each other and connected.
[0024] A figure-eight rotating hole 17 is formed inwardly at the end of each side 5, and a rotating arm 16 is provided at the end of each engaging plate 10. The rotating arm 16 is inserted into the figure-eight rotating hole. In the front rotating hole of the hole 17, a limiting boss 18 is provided at the end of each side 5. The limiting boss 18 extends into the rear hole 17 of the figure-eight rotating hole for limiting the rotating arm 16. A notch is provided at the lower end of the rear hole of the eight-shaped rotating hole 17.
[0025] In the flip-type SIM card holder of the present utility model, the two rotating arms 16 of the cover body 1 enter the figure-eight rotating hole 17 through the gap in the rear hole of the figure-eight-shaped rotating hole 17, and can be inserted into the figure-eight-shaped rotating hole 17. Rotate in the front hole, and the limiting boss on the engaging plate 10 extends into the rear hole 17 of the eight-shaped rotating hole to limit the position of the rotating arm 16 to prevent the cover 1 from plastic when the clamshell SM card holder is opened. The main body 2 is detached, making it safer and more convenient to use.
[0026] In the flip-type SM card holder of the present invention, after the end of the cover 1 is hinged with the end of the plastic body 2, the cover 1 is rotated and closed with the plastic body 2, and the hook 11 is opposite to the engaging plate 10 The clamping cavity 20 formed in the position covers the card body 12 and is compressed and clamped by friction between the protrusions and the side of the card body. This ensures that the SIM card holder will not move randomly in the up and down direction.
[0027] After the clamshell SM card holder of the present utility model is closed, the positioning buckle 8 falls into the first positioning groove 6 for positioning. In order to realize the normal operation of the SIM card, the cover body 1 is pushed to move, so that the positioning buckle 8 slides into the second positioning slot 7 for positioning, and the positioning buckle 8 cooperates with the first positioning slot 6 and the second positioning slot 7 to realize the positioning of the SIM card holder in the front and rear directions, ensuring that it will not move during use. . At the same time, when the buckle 8 slides into the second positioning groove 7, the inner wall of the plywood 10 just contacts and squeezes the cantilever 15, so that the first switch PIN pin 13 and the second switch PIN pin 14 are in contact with each other and connected.
[0028] In summary, the flip-type SIM card holder of the present invention has a positioning buckle 8 formed by an inward recess in the middle of each engaging plate 10. The positioning buckle 8 is connected to the positioning groove on the side. Cooperate so that the SIM card holder will not move in the front and rear directions. At the same time, a hook 11 extends downward from the front end and bottom of the top plate 9. The hook 11 is opposite to the engaging plate 10 on one side to form a clamping cavity 20. The clamping between the protrusions of the clamping cavity and the card body 12 prevents the cover of the SM card holder from rotating upward during use. Through the above structure, the SM card holder is fixed in the up, down and front and rear directions. During use, , safer and more reliable. In addition, the rotating arm 16 of the utility model is inserted into the front rotating hole of the figure-eight rotating hole 17, and a limiting boss 18 is provided at the end of each side 5. The limiting boss 18 extends into the rear hole of the figure-eight rotating hole 17, so that When the cover 1 is in the open state, due to the limitation of the limiting boss 18 at its rear end, the cover 1 will not slip out of the eight-shaped rotating hole 17, and the design is more ingenious.
