Technical field
[000 1] The utility model relates to an SM seat connector, in particular to a clamshell SM card seat.
technical background
[0002]SIM card is the abbreviation of (subscriber identity module), also known as smart card and subscriber identity card. GSM digital mobile phone can only use this card. It stores the information of digital mobile phone customers, encryption keys and user's phone book on a computer chip, which can be used to identify GSM network customers and encrypt voice information when customers talk.
[0003] The existing clamshell SM card holder generally has eight pin terminals, which are connected with the SM card. However, after installing the SIM card, the existing flip SIM card holder is not stable enough. During use, the cover and plastic body are easy to loosen, which affects the normal use of SM card. At the same time, the flip SIM card unscrews the cover, so when the cover and the plastic body are in the open state, the cover is very easy to slide off the plastic body because there is no limit, and it needs to be reinstalled, which wastes time.

[0020] The utility model will be further described with the attached drawings.
[002 1] As shown in figure 1-6, the clamshell SM card holder includes a cover 1, a plastic body 2 and pins 3, wherein the end of the cover 1 is hinged with the end of the plastic body 2, and the plastic body 2 includes a bottom plate 4 and side edges 5 located at both sides of the bottom plate 4, and eight pins 3 are arranged on the bottom plate 4. The outer wall of the middle part of each side edge 5 is provided with a first positioning groove 6 and a second positioning groove 7 which are connected in waves, and the front end of one side edge 5 is recessed inward to form a clamping body 12. The cover I comprises a top plate 9 and clamping plates 10 located on both sides of the top plate 9, and the middle part of the clamping plate 10 is concavely provided with positioning buttons 8 which can extend into the positioning grooves on the corresponding sides. The connection position between the top plate 9 above the positioning buckle 8 and the splint 10 is set to hollow 19, which is convenient for the positioning groove of the positioning buckle 8 to cooperate.
[0022] The hook 1 1 extends downward from the bottom of the front end of the top plate 9. The hook 1 1 forms a clamping cavity 20 at a position close to the splint 10, and the hook 1 1 is opposite to the splint 10.
[0023] A first switch pin 13 and a second switch pin 14 which can contact each other are arranged at the front end of the other side 5 corresponding to the card body 12 side, and a cantilever 15 is arranged at the tail end of the second switch pin 14 which extends out of the outer wall of the other side 5. The inner wall of the clamping plate 10 on the opposite side can contact the extrusion cantilever 15, so that the first switch pin 13 and the second switch pin 14 contact each other and conduct.
[0024] The end of each side 5 is concavely provided with a splayed rotating hole 17, and the end of each splint 10 is provided with a rotating arm 16. The rotary arm 16 is inserted into the front rotary hole of the splayed rotary hole 17, and the end of each side 5 is provided with a limit boss 18. The limiting boss 18 extends into the back hole 17 of the splayed rotating hole for limiting the rotating arm 16, and the lower end of the back hole of the splayed rotating hole 17 is provided with a notch.
[0025] In the clamshell SIM card holder of the utility model, the two rotating arms 16 of the cover I enter the splayed rotating hole 17 through the gap in the back hole of the splayed rotating hole 17 and can rotate in the front hole, and the limiting boss on the splint 10 extends into the splayed rotating hole/kloc.
[0026] The utility model relates to a clamshell SM card holder. When the end of the cover I is hinged with the end of the plastic body 2, the cover I rotates and closes with the plastic body 2. The clamping cavity 20 formed by the relative positions of the hook 1 1 and the splint 10 covers the card body 12, and the bumps are used for pressing and clamping, thus ensuring the SIM card.
[0027] After the clamshell SM card holder is closed, the positioning button 8 falls into the first positioning slot 6 for positioning. In order to realize the normal operation of the SIM card, the cover I is pushed to move, so that the positioning button 8 slides into the second positioning slot 7 for positioning. Through the cooperation of the positioning button 8 with the first positioning groove 6 and the second positioning groove 7, the positioning of the SIM card holder in the front and rear direction is realized, and it is ensured that it will not move during use. At the same time, when the stopper 8 slides into the second positioning groove 7, the inner wall of the hinge plate 10 just contacts the extrusion cantilever 15, so that the first switch pin 13 and the second switch pin pin 14 contact and conduct each other.
[0028] To sum up, in the clamshell SIM card holder of this utility model, a positioning button 8 is formed in the middle of each splint 10, and the positioning button 8 is matched with the positioning groove on the side to prevent the SIM card holder from moving back and forth, and at the same time, a hook 1 1 extends downward from the bottom of the front end of the top plate 9. The hook 1 1 and the splint 10 near one side form a clamping cavity 20. The cover of the SM card holder will not rotate upward and open during use by clamping the convex points of the clamping cavity and the clamping body 12. Through the above structure, the SM card holder is fixed in the four directions of up, down, front and back, which is safer and more reliable in use. In addition, the rotary arm 16 of the utility model is inserted into the front rotary hole of the splayed rotary hole 17, and the limiting boss 18 is arranged at the end of each side 5, and the limiting boss 18 extends into the rear hole of the splayed rotary hole 17, so that when the cover I is in the open state,
