[0028] The utility model provides a SIM card connector 100 .

[0029] See also Figure 1 and Figure 2 The SIM card connector 100 of the utility model includes a card holder 10 and a card tray 20 slidably connected to the card holder 10. The side of the card holder 10 facing the card tray 20 is provided with two oppositely arranged detection terminals 11 and a plurality of arranged signal terminals 12. The two detection terminals 11 are arranged on the outer side of the signal terminals 12 at the edge. The side of the card tray 20 facing the card holder 10 is recessed with a card slot 21 for placing the SIM card 200. The peripheral side of the card slot 21 is provided with a wiring terminal 22. When the card tray 20 slides into the card holder 10, the wiring terminal 22 slides between the two detection terminals 11 and connects the two detection terminals 11.

[0030] The SIM card connector 100 can be applied to communication devices such as mobile phones, tablets and telephone watches, so that the communication devices have communication functions. The embodiment of the SIM card connector 100 of the utility model includes a card holder 10 and a card tray 20. The card tray 20 is provided with a card slot 21 for placing the SIM card 200, and the card tray 20 is connected to the card holder 10 in a sliding manner. The user can apply force to the card tray 20 so as to slide the card tray 20 out of the card holder 10, thereby taking out or placing the SIM card 200. Among them, the card holder 10 is provided with a plurality of signal terminals 12 arranged in an array, and the SIM card 200 is provided with a plurality of metal contacts. When the SIM card 200 slides to a specified position with the card tray 20, each metal contact on the SIM card 200 contacts and conducts with the signal terminal 12 on the card holder 10, thereby realizing the signal interaction between the SIM card 200 and the communication device, thereby realizing the communication function of the communication device.

[0031] In order to realize the detection function when the SIM card 200 is inserted or removed, the conventional SIM card connector is usually provided with a single detection terminal on the card tray 20, and a metal terminal for contacting and conducting with the detection terminal is provided on the card holder 10. When the card tray 20 is inserted into the card holder 10, the detection terminal is in contact with the metal terminal for conduction, and when the card tray 20 is withdrawn, the detection terminal 11 is separated from the metal terminal. At present, most SIM card connectors usually insert the metal terminal for detecting the insertion or removal of the SIM card 200 between two arranged signal terminals, so that the detection terminal is easy to accidentally touch other signal terminals during the insertion or removal process, resulting in misjudgment.

[0032] Unlike the traditional SIM card connector, the SIM card connector 100 of the present invention sets the detection terminal 11 on the outside of the signal terminal 12 at the edge, and there are two detection terminals 11, and the two detection terminals 11 are arranged opposite to each other and spaced apart. At the same time, a wiring terminal 22 is arranged on the side of the card tray 20 facing the card holder 10. When the card tray 20 slides to the specified position with the SIM card 200, the wiring terminal 22 is just located between the two detection terminals 11 to connect the two wiring terminals 22, and the system of the communication device recognizes that a card is inserted. When the wiring terminal 22 slides out with the card tray 20, the two detection terminals 11 are disconnected, and the system of the communication device recognizes that the SIM card 200 is pulled out, thereby realizing the detection function when the SIM card 200 is inserted or pulled out. The SIM card connector 100 sets the detection terminal 11 and the wiring terminal 22 at the edge position, which can prevent the wiring terminal 22 from accidentally touching other signal terminals 12 during the insertion and removal process to a certain extent. On the other hand, the SIM card connector 100 determines the insertion and removal of the SIM card 200 by detecting the connection and disconnection of the two detection terminals 11. Even if the wiring terminal 22 accidentally touches the signal terminal 12 during the insertion and removal process, it will not affect the connection and disconnection status of the two detection terminals 11, thereby not affecting the detection result of the system, thereby improving the accuracy of the insertion and removal detection of the SIM card 200.

[0033] Reference Figure 3 In one embodiment of the utility model, the connection terminal 22 includes a connection portion 221 and a clamping portion 222. The connection portion 221 is a metal sheet structure, which is used to connect the two detection terminals 11. The clamping portion 222 is arranged at the edge of the connection portion 221 and is bent with the connection portion 221. The card holder 20 is provided with a clamping hole 23 adapted to the clamping portion 222. The clamping portion 222 is inserted into the clamping hole 23 to achieve the limited installation of the connection terminal 22 and the card holder 20.

[0034] At the same time, a placement groove 24 for installing the wiring terminal 22 is also recessed on the side of the card tray 20 facing the card holder 10, and the card connection hole 23 is provided on the bottom wall of the placement groove 24. The size of the placement groove 24 is at least equal to the size of the wiring portion 221, and the recessed depth of the placement groove 24 is equal to the thickness of the wiring terminal 22. The size of the card slot 21 on the card tray 20 is consistent with the size of the standard SIM card 200, the recessed depth of the card slot 21 is equal to the thickness of the SIM card 200, and the recessed depth of the placement groove 24 is equal to the thickness of the wiring terminal 22. When the SIM card 200 is placed in the card slot 21, the outer surface of the wiring portion 221 is flush with the outer surface of the SIM card 200, thereby ensuring the flatness of the sliding surface of the card tray 20 and ensuring the smooth sliding of the card tray 20.

[0035] Reference Figure 5A side of the card holder 10 facing the card tray 20 is recessed with a slide groove 13 that runs through the card tray 20 from front to back. The front and back directions here refer to the directions in which the card tray 20 slides in and out. The card tray 20 is slidably set in the slide groove 13, and a first mounting groove 14 is recessed on the bottom wall of the slide groove 13.

[0036] Reference Figure 4 The detection terminal 11 has a fixing portion 111 and a cantilever 112 cantilevered from the fixing portion 111. The fixing portion 111 is fixedly installed in the first mounting groove 14. The cantilever 112 is tilted toward the notch of the first mounting groove 14. When the card tray 20 does not slide into the slide groove 13, the free end of the cantilever 112 protrudes from the notch of the first mounting groove 14 to form a contact portion. When the card tray 20 slides into the slide groove 13, the terminal 22 contacts and presses the contact portion.

[0037] It should be noted that the detection terminal 11 is a metal terminal with conductive properties, and the fixing portion 111 and the cantilever 112 are connected as a whole, and the cantilever 112 has a certain bending performance and elastic force, and can bend with the fixing portion 111 as the center when under pressure, and return to its original shape after the pressure disappears. Among them, the fixing portion 111 is fixedly installed in the first installation groove 14, and the cantilever 112 is tilted toward the notch of the first installation groove 14, that is, the cantilever 112 gradually tilts outward from the end connected to the fixing portion 111 to the end away from the fixing portion 111, so that the free end of the cantilever 112 emerges from the first installation groove 14. When the card tray 20 has not slid into the slide groove 13 (initial state), the free end of the cantilever 112 protrudes from the notch of the first mounting groove 14 to form a contact portion. When the card tray 20 slides into the slide groove 13, the connecting terminal 22 on the card tray 20 presses down the contact portion of the cantilever 112, and the connecting terminal 22 and the detection terminal 11 press against each other, so that the connecting terminal 22 and the detection terminal 11 are in close contact, thereby ensuring the stability of the contact between the two.

[0038] Further, in Figure 4 In the illustrated embodiment, an end of the cantilever 112 away from the fixing portion 111 is formed with an arched portion 113 , and the arched portion 113 serves as a contact portion to contact and press the connection terminal 22 , thereby increasing the contact area between the detection terminal 11 and the connection terminal 22 .

[0039] At the same time, the two detection terminals 11 are symmetrically arranged, that is, the arched portions 113 of the two detection terminals 11 are relatively arranged, so that the arched portions 113 of the two detection terminals 11 are simultaneously pressed against the wiring terminal 22, thereby increasing the squeezing force on the wiring terminal 22 and further ensuring the stability of the contact between the detection terminal 11 and the wiring terminal 22.

[0040] Reference Figure 5 and Figure 6The first mounting groove 14 for mounting the detection terminal 11 includes a first sub-mounting groove 141 and a second sub-mounting groove 142. The first sub-mounting groove 141 is located at one end of the second sub-mounting groove 142 and is connected to the second sub-mounting groove 142. The depression depth of the first sub-mounting groove 141 is less than the depression depth of the second sub-mounting groove 142. The first sub-mounting groove 141 is provided with a recessed clamping groove 143 on both sides. The fixing portion 111 is provided with a protruding clamping block 114 on both sides. The protruding width of the clamping block 114 is consistent with the depression depth of the clamping groove 143. The fixing portion 111 is arranged in the first sub-mounting groove 141, the cantilever 112 is arranged in the second sub-mounting groove 142, and the clamping block 114 is embedded in the clamping groove 143, so as to realize the connection between the detection terminal 11 and the card holder 10. The cantilever 112 is cantilevered from the second sub-mounting groove 142, and the second mounting groove 17 provides space for the bending deformation of the cantilever 112.

[0041] At the same time, an end of the arched portion 113 away from the fixed portion 111 is provided with an abutment block 115 protruding outward, and a side wall of the second sub-mounting groove 142 away from the first sub-mounting groove 141 is provided with a blocking block 15 protruding. The top surface of the blocking block 15 is flush with the top surface of the card holder 10, and a movable gap 16 is formed between the bottom surface of the blocking block 15 and the bottom wall of the second sub-mounting groove 142. The abutment block 115 is movably arranged in the movable gap 16. Among them, the width of the movable gap 16 is greater than the thickness of the abutment block 115, so that the abutment block 115 can move up and down in the movable gap 16. When the arched portion 113 is pressed by the connecting terminal 22, the arched portion 113 drives the abutment block 115 to move downward. When the card holder 20 is pulled out, the pressure on the arched portion 113 disappears, and the cantilever 112 is lifted upward under the action of its own elastic force until the abutment block 115 and the blocking block 15 abut against each other. Therefore, the stopper 15 is used to limit the cantilever 112 from excessively protruding.

[0042] In the present SIM card connector 100, the card holder 10 is further provided with a second mounting groove 17 for mounting the signal terminal 12, and the structure of the signal terminal 12 is consistent with that of the detection terminal 11, and the structure of the second mounting groove 17 is consistent with that of the first mounting groove 14, which will not be repeated here.

[0043] The utility model also proposes a communication device, which can be an electronic device such as a mobile phone, a tablet, and a phone watch. The communication device includes a SIM card connector 100. The specific structure of the SIM card connector 100 refers to the above embodiment. Since the communication device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0044] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
