Specifically, the electronic device can perform mobile communication through a Subscriber Identity Module (SIM) card. The electronic device includes a card seat for accommodating the SIM card, and detects whether the SIM card is inserted into the card seat through the card seat and the SIM card. However, in the related art, the accuracy of the electronic device detecting whether the SIM card is inserted into the card seat is not high. SUMMARY

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0039] This application provides a card holder; please refer to the specific details. Figure 1 and Figure 2 , Figure 1This is a schematic diagram of the card holder provided in an embodiment of this application. Figure 2 for Figure 1 An exploded view of the card slot shown.

[0040] The card holder 100 can be used to accommodate a Subscriber Identity Module (SIM) card. The card holder 100 may include a bracket 120, a connector 140, and a detection spring 160. Both the connector 140 and the detection spring 160 are disposed on the bracket 120. When the SIM card is not inserted into the card holder 100, the detection spring 160 is electrically connected to the connector 140. When the SIM card is inserted into the card holder 100, the detection spring 160 and the connector 140 are spaced apart. The connection status of the detection spring 160 and the connector 140 can be used to determine whether a SIM card is inserted into the card holder 100. The physical contact and separation of the detection spring 160 and the connector 140 accurately determines whether a SIM card is inserted into the card holder 100, thereby improving the accuracy of SIM card insertion detection.

[0041] It should be noted that in the relevant technology, the card slot is equipped with a detection circuit connected to the SIM card. When the SIM card is not inserted into the card slot, the detection circuit is open. When the SIM card is inserted into the card slot, the detection circuit is electrically connected to the SIM card, thus forming a loop and detecting that the SIM card is inserted into the card slot. However, if the SIM card is not properly inserted into the card slot or the SIM card is invalid, it cannot be effectively detected.

[0042] This embodiment detects whether a SIM card is inserted into the card slot 100 by detecting the physical connection between the detection spring 160 and the connector 140. When the SIM card is not inserted into the card slot 100, the detection spring 160 and the connector 140 abut against each other to achieve electrical connection. When the SIM card is inserted into the card slot 100, the detection spring 160 is squeezed by the SIM card, causing it to separate from the connector 140, so that the detection spring 160 and the connector 140 are spaced apart, and the voltage level of the detection spring 160 is no longer affected by the connector 140. For example, when the SIM card is not inserted into the card slot 100, the detection spring 160 is electrically connected to the connector 140. The connector 140 affects the voltage level of the detection spring 160. For example, if the voltage level of the detection spring 160 is low, when the SIM card is inserted into the card slot 100, the detection spring 160 is squeezed by the SIM card, causing it to separate from the connector 140. The voltage level of the detection spring 160 is no longer pulled low by the connector 140, and the detection spring 160 changes from low to high. Therefore, the voltage level change of the detection spring 160 can be used to identify whether a SIM card is inserted. The voltage level change of the detection spring 160 is determined by the physical connection or physical separation between the detection spring 160 and the connector 140. Even if the SIM card is not fully inserted into the card slot 100 or the SIM card is invalid, it does not affect the detection of the detection spring 160, and the detection of whether the SIM card is inserted into the card slot 100 can be accurately detected.

[0043] It should be noted that the first and second voltage levels can be set as needed. For example, in some other embodiments, when the SIM card is not inserted into the card slot, the detection spring is electrically connected to the connector, so that the voltage level of the detection spring is high. When the SIM card is inserted into the card slot, the detection spring is squeezed by the SIM card, causing it to separate from the connector, and the voltage level of the detection spring changes from high to low.

[0044] Please combine Figure 3 , Figure 4 and Figure 5 , Figure 3 for Figure 2 The diagram shows the structure of the bracket, connector, and detection spring in the card slot. Figure 4 for Figure 3 An enlarged schematic diagram of part A in the structure shown. Figure 5 for Figure 2 The diagram shows the structure of the connector in the card holder. The connector 140 may include a connecting portion 142 and a blocking portion 144. The connecting portion 142 is connected to the bracket 120 and is spaced apart from the detection spring 160. The blocking portion 144 protrudes from the connecting portion 142 toward the detection spring 160. When the customer identification card is not inserted into the card holder 100, the detection spring 160 abuts against the blocking portion 144; when the customer identification card is inserted into the card holder 100, the detection spring 160 separates from the blocking portion 144. The blocking portion 144, protruding from the connecting portion 142, can block the detection spring 160, thereby allowing it to abut against and electrically connect with the detection spring 160. It should be noted that when the customer identification card is not inserted into the card holder 100, the blocking part 144 abuts against the detection spring 160, causing the detection spring 160 to undergo a certain elastic deformation, thereby ensuring that the detection spring 160 and the blocking part 144 are tightly abutted, guaranteeing the stability of the electrical connection between the detection spring 160 and the blocking part 144. When the customer identification card is inserted into the card holder 100, the customer identification card will squeeze the elastic spring. Because the blocking part 144 protrudes from the connecting part 142, the elastic spring can be easily squeezed open by external force, thereby separating from the blocking part 144 and spaced apart from the connecting member 140.

[0045] Please continue reading. Figure 1 and Figure 2 The card holder 100 may also include a top shell 180, which is mounted on the bracket 120 and forms a receiving space 190 with the bracket 120 for receiving a customer identification card.

[0046] Please combine Figure 6 , Figure 6 for Figure 2The diagram shows the structure of the bracket in the card holder. The bracket 120 may include a base plate 122 and a side plate 124. The side plate 124 protrudes from the base plate 122, and the base plate 122 is connected to the top shell 180 through the side plate 124. The base plate 122, the side plate 124, and the top shell 180 surround to form the receiving space 190. A detection spring 160 is disposed on the side plate 124, and a connector 140 is disposed on the base plate 122. The detection spring 160 and the connector 140 are spatially offset, which can also be understood as the detection spring 160 being located above the connector 140, facilitating the contact and separation of the detection spring 160 and the connector 140.

[0047] The connecting part 142 can be disposed on the base plate 122, and the blocking part 144 protrudes towards the top shell 180. That is, the blocking part 144 is disposed between the base plate 122 and the top shell 180, facilitating the opening of the blocking part 144 when the customer's identification card is inserted into the receiving space 190 between the base plate 122 and the top shell 180. Alternatively, the connecting part 142 can be disposed on the side of the base plate 122 away from the top shell 180, or on the side of the base plate 122 facing the top shell 180. The connecting part 142 can be fixed to the base plate 122 by snap-fit, adhesive, or screw connection. The connecting part 142 can also be embedded in the base plate 122, such as by injection molding.

[0048] The blocking part 144 can be made of metal and is elastic. The blocking part 144 can be bent to connect to the connecting part 142, meaning there is a preset angle between the blocking part 144 and the connecting part 142. This preset angle can be greater than 90 degrees, such as 120 degrees, 135 degrees, or 150 degrees. The blocking part 144 can be located at the edge of the connecting member 140, and there is a gap between the blocking part 144 and the connecting part 142. The blocking part 144 can be connected to the connecting part 142 at only one end, allowing the blocking part 144 to easily undergo elastic deformation, facilitating contact with and separation from the detection spring 160. The connecting member 140 can be a metal connecting member, meaning the connecting part 142 can also be made of metal. Of course, the connecting part 142 can also be made of other materials, such as plastic.

[0049] Understandably, the top cover 180 can be made of metal. A metal top cover 180 has high hardness, which can effectively protect the SIM card underneath. Furthermore, the metal top cover 180 can serve as ground for the card slot 100, improving the stability of the SIM card signal within the card slot 100. The detection spring 160 is mounted on the bracket 120. The bracket 120 can be made of a non-conductive material such as plastic. The bracket 120 is non-conductive and will not affect the voltage level of the detection spring. The detection spring 160 and the top cover 180 are always spaced apart, and the detection spring 160 will not be pulled low by the ground of the top cover 180; that is, the top cover will not affect the detection of the detection spring 160.

[0050] Please combine Figure 7 , Figure 8 and Figure 9 , Figure 7 for Figure 2 The diagram shown is a structural schematic of the bracket, connector, and detection spring in the card holder from another angle. Figure 8 for Figure 7 An enlarged schematic diagram of part B in the structure shown. Figure 9 for Figure 2 The diagram shows the structure of the detection spring 160 in the card slot. The detection spring 160 includes a fixing part 162 and an elastic part 164. The fixing part 162 is connected to the edge of the base plate, and the elastic part 164 is elastic. When the customer identification card is not inserted into the card slot 100, the elastic part 164 abuts against the blocking part 144. When the customer identification card is inserted into the card slot 100, the elastic part 164 undergoes elastic deformation and separates from the blocking part 144. The detection spring 160 can be a metal spring, and the material of the elastic part 164 is metal. The metal elastic part 164 is both elastic and conductive. The elastic part 164 is connected to the edge of the base plate through the fixing part 162. The elastic part 164 is a free end, and the elastic part 164 is easily separated from the blocking part 144 by the SIM card. When the SIM card is removed, the elastic part 164 can easily rebound due to its elastic restoring force, thereby abutting against the blocking part 144.

[0051] The fixing part 162 and the elastic part 164 can be directly connected, that is, the fixing part 162 and the elastic part 164 form the detection spring 160. The fixing part 162 and the elastic part 164 can also be connected through an intermediate part. The detection spring 160 can also be formed by splicing metal and non-conductive parts such as plastic, with the elastic part 164 made of metal and the fixing part 162 made of plastic. The elastic part 164 is fixedly connected to the fixing part 162, such as by partially inserting the elastic part 164 into the fixing part 162 or by splicing the elastic part 164 and the fixing part 162 through injection molding.

[0052] The base plate 122 has a first notch 1222, and a blocking part 144 is disposed in the first notch 1222. A detection spring is bent from the edge of the base plate 122 and disposed in the first notch 1222. The detection spring extends by bending, and the elastic part 164 has a large bending angle, providing a large movement distance. When the SIM card is inserted into the card holder 100, it can push the elastic part 164 to move a large distance, making its contact or separation with the connecting part 142 very obvious. Even if the SIM card is not fully inserted, the elastic part 164 and the blocking part 144 can be separated effectively. Furthermore, the fixing part 162 is connected to the edge of the base plate, and the elastic part 164 being disposed in the first notch 1222 does not increase the overall volume of the card holder 100, making the overall structure of the card holder 100 compact and small. Similarly, the blocking part 144, disposed in the first notch 1222, can effectively block the elastic part 164 while reducing its space occupation. The surface of the blocking part 144 facing the top cover 180 may not exceed the surface of the bottom plate 122 facing the top cover 180, so as not to affect the insertion and removal of the SIM card. Of course, the surface of the blocking part 144 facing the top cover 180 may also exceed the surface of the bottom plate 122 facing the top cover 180.

[0053] When the customer identification card is not inserted into the card holder 100, the elastic part 164 is disposed between the base plate 122 and the blocking part 144. The side of the elastic part 164 facing the blocking part 144 abuts against the blocking part 144, and the side of the elastic part 164 away from the blocking part 144 abuts against the base plate 122. The end of the elastic part 164 near the fixing part 162 abuts against the blocking part 144, and the end of the elastic part 164 away from the fixing part 162 abuts against the base plate 122. The blocking part 144 and the bottom are located on both sides of the elastic part 164, and cause the elastic part 164 to produce a certain elastic deformation, which can effectively restrict the elastic part 164. The elastic part 164 is disposed within the first notch 1222, and the elastic part 164 can abut against the sidewall of the base plate 122 forming the first notch 1222. The elastic part 164 also includes a portion extending beyond the sidewall, which can be squeezed and pushed open by the customer identification card.

[0054] The end of the elastic portion 164 away from the fixed portion 162 may include an abutting portion 1642 and a warping portion 1644. The warping portion 1644 is located at the end of the elastic portion 164, that is, the fixed portion 162 is connected to the warping portion 1644 through the abutting portion 1642. When the customer identification card is not inserted into the card holder 100, the abutting portion 1642 abuts against the base plate 122, and the warping portion 1644 is spaced apart from the base plate 122. The warping portion 1644 extends from the abutting portion 1642 in a direction away from the base plate 122. When the customer identification card is pulled out, the warping portion 1644 enables the elastic portion 164 to provide better elastic force, so that the elastic portion 164 returns to the state before the customer identification card is not inserted into the card holder 100.

[0055] Optionally, the connector may have a receiving structure. When the SIM card is not inserted into the card slot, the detection spring includes an elastic structure located within the receiving structure, and the elastic structure abuts against the sidewall forming the receiving structure, thereby achieving electrical connection between the detection spring and the connector. When the SIM card is inserted into the card slot, the elastic structure separates from the connector. For example, the receiving structure is a groove, and the elastic structure exits from the groove opening and separates from the connector. Another example is a receiving hole, where the elastic structure undergoes elastic deformation and bends away from one side of the receiving hole.

[0056] This application also provides a card holder; please refer to the following embodiments. Figure 1 and combined Figure 10 and Figure 11 , Figure 10 for Figure 1 Another structural diagram of the bracket, connector, and detection spring in the card holder is shown. Figure 11 for Figure 10 The diagram shows an enlarged view of part C in the structure shown. The card holder 100 is used to accommodate a customer identification card. The card holder 100 includes a bracket 120, a connector 140, and a detection spring 160. Both the connector 140 and the detection spring 160 are disposed on the bracket 120. The main difference between the card holder 100 in this embodiment and the card holder 100 in the previous embodiment is that when the customer identification card is not inserted into the card holder 100, the detection spring 160 and the connector 140 are spaced apart; when the customer identification card is inserted into the card holder 100, the detection spring 160 and the connector 140 are electrically connected. The connection status of the detection spring 160 and the connector 140 can be used to determine whether a SIM card is inserted into the card holder 100. The physical contact and separation of the detection spring 160 and the connector 140 accurately determines whether a SIM card is inserted into the card holder 100, thus ensuring high accuracy in detecting whether a SIM card is inserted into the card holder 100.

[0057] It should be noted that in the relevant technology, the card slot is equipped with a detection circuit that is connected to the SIM card. When the SIM card is not inserted into the card slot, the detection circuit is open. When the SIM card is inserted into the card slot, the detection circuit is electrically connected to the SIM card to form a loop, thereby detecting that the SIM card has been inserted into the card slot.

[0058] However, if the SIM card is not properly inserted into the card slot 100 or the SIM card is invalid, effective detection is not possible. This embodiment detects whether a SIM card is inserted into the card slot 100 by detecting the physical connection between the detection spring 160 and the connector 140. When the SIM card is not inserted into the card slot 100, the detection spring 160 and the connector 140 are spaced apart, and the voltage level of the detection spring 160 is not affected by the connector 140. When the SIM card is inserted into the card slot 100, the detection spring 160 is pressed by the SIM card, causing it to abut against the connector 140, thus electrically connecting the detection spring 160 and the connector 140. The voltage level of the detection spring 160 is then affected by the connector 140. For example, when the SIM card is not inserted into the card slot 100, the detection spring 160 is spaced apart from the connector 140, and the level of the detection spring 160 is low. When the SIM card is inserted into the card slot 100, the detection spring 160 is pressed by the SIM card, making it abut against the connector 140 and electrically connected, and the level of the detection spring 160 changes from low to high. Therefore, the level change of the detection spring 160 can be used to identify whether a SIM card is inserted. The level change of the detection spring 160 is determined by the physical connection or physical separation of the detection spring 160 and the connector 140. Even if the SIM card is not fully inserted into the card slot 100 or the SIM card is invalid, it does not affect the detection of the detection spring 160, and the SIM card can be accurately detected as to whether the SIM card is inserted into the card slot 100.

[0059] It should be noted that the first and second voltage levels can be set as needed. For example, in some other embodiments, when the SIM card is not inserted into the card slot, the detection spring is spaced apart from the connector so that the voltage level of the detection spring is high. When the SIM card is inserted into the card slot, the detection spring is pressed by the SIM card so that it abuts against the connector and is electrically connected, and the voltage level of the detection spring changes from high to low.

[0060] In this embodiment, the connector 140 may include a connecting portion 142 and a blocking portion 144. The connecting portion 142 is connected to the base plate 122, and the blocking portion 144 protrudes from the connecting portion 142. When the customer identification card is not inserted into the card holder 100, the blocking portion 144 is separated from the connector 140. When the customer identification card is inserted into the card holder 100, the detection spring 160 abuts against and is electrically connected to the blocking portion 144. The blocking portion 144, which protrudes from the connecting portion 142, can abut against the detection spring 160, thereby abutting against and electrically connecting with the detection spring 160. It should be noted that when the customer identification card is inserted into the card holder 100, the detection spring 160 is squeezed by the SIM card and undergoes elastic deformation, abutting against the blocking portion 144. When the customer identification card is pulled out of the card holder 100, the detection spring 160 rebounds, thereby separating from the blocking portion 144.

[0061] The detection spring 160 in this embodiment includes a fixing part 162 and an elastic part 164. The fixing part 162 is connected to the side plate 124, and the elastic part 164 is elastic. When the customer identification card is not inserted into the card holder 100, the elastic part 164 and the blocking part 144 are spaced apart. When the customer identification card is inserted into the card holder 100, the elastic part 164 undergoes elastic deformation and abuts against the blocking part 144. The detection spring 160 can be a metal spring, and the material of the elastic part 164 is metal. The metal elastic part 164 is both elastic and conductive. The elastic part 164 is connected to the side plate 124 through the fixing part 162. The elastic part 164 is a free end, and the elastic part 164 is easily separated from the blocking part 144 by the SIM card. When the SIM card is removed, the elastic part 164 can easily rebound due to its elastic restoring force, thereby separating from the blocking part 144.

[0062] The base plate 122 has a first notch 1222, and a blocking part 144 is disposed in the first notch 1222. The detection spring is bent from the edge of the base plate and disposed in the first notch 1222. The detection spring has a large bending angle, which can provide a large movement distance. When the SIM card is inserted into the card holder 100, it can push the elastic part 164 to move a large distance, and the contact or separation with the connecting part 142 is very obvious.

[0063] When the customer identification card is not inserted into the card slot 100, the elastic part 164 is disposed between the base plate 122 and the blocking part 144. The side of the elastic part 164 facing the base plate 122 abuts against the blocking part 144, while the side of the elastic part 164 away from the base plate 122 is spaced apart from and opposite to the base plate 122. When the customer identification card is inserted into the card slot 100, the elastic part 164 is pushed by the SIM card, and the end of the elastic part 164 away from the fixed part 162 can abut against the blocking part 144. It should be noted that the end of the elastic part 164 away from the fixed part 162 is a free end, which is prone to elastic deformation, and maintains abutment against the blocking part 144 according to the elastic restoring force generated by the elastic deformation. For example, during the process of the elastic part 164 being squeezed and pushed by the SIM card, after the end of the elastic part 164 away from the fixed part 162 touches the blocking part 144, it is still squeezed and pushed, thereby causing the end of the elastic part 164 away from the fixed part 162 to undergo elastic deformation. The elastic restoring force generated by the elastic deformation keeps the end of the elastic part 164 away from the fixed part 162 in contact with the blocking part 144.

[0064] The end of the elastic portion 164 away from the fixed portion 162 may include an abutting portion 1642 and a warped portion 1644. The warped portion 1644 is located at the end of the elastic portion 164, that is, the fixed portion 162 is connected to the warped portion 1644 through the abutting portion 1642. When the customer identification card is not inserted into the card holder 100, the abutting portion 1642 abuts against the base plate 122, and the warped portion 1644 is spaced apart from the base plate 122, extending from the abutting portion 1642 in a direction away from the base plate 122. When the customer identification card is inserted into the card holder 100, both the abutting portion 1642 and the warped portion 1644 are pushed and squeezed. After the warped portion 1644 touches the blocking portion 144, the abutting portion 1642 and the warped portion 1644 are still pushed and squeezed, thereby causing the warped portion 1644 to undergo elastic deformation. The elastic restoring force of the warped portion 1644 keeps it abutting against the blocking portion 144.

[0065] Other structures of the card holder in this embodiment can be found in the card holder structures described in the above embodiments, and will not be repeated here.

[0066] This application also provides an electronic device; please refer to [link / reference]. Figures 12 to 15 , Figure 12 This is a schematic diagram of the structure of the electronic device provided in the embodiments of this application. Figure 13 for Figure 12 The diagram shows a first structural representation of the circuit board in the electronic device. Figure 14 for Figure 13 A schematic diagram of the substrate structure in the circuit board shown. Figure 15 for Figure 13 The diagram shows a partial structural schematic of the card holder in the circuit board. The electronic device 1 includes a housing 12 and a circuit board 10. The circuit board 10 is mounted on the housing 12. The circuit board 10 includes a substrate 200 and a card holder 100. The card holder 100 is disposed on the substrate 200. The structure of the card holder 100 can be referred to in any of the above embodiments, and will not be repeated here.

[0067] Please combine Figures 1 to 15 When the customer identification card is not inserted into the card slot 100, the level of the detection spring 160 is the first level. When the customer identification card is inserted into the card slot 100, the level of the detection spring 160 is the second level, which is different from the first level.

[0068] Specifically, the connector 140 includes a soldering end 146, which is electrically connected to a first solder pad 210 on the substrate 200. When the customer identification card is not inserted into the card holder 100, the first solder pad 210 is electrically connected to the detection spring 160 through the connector 140, and the first solder pad 210 causes the voltage level of the detection spring 160 to be a first voltage level. The first solder pad 210 on the substrate 200 is electrically connected to the connector 140 through the soldering end 146, and the connector 140 is electrically connected to the detection spring 160, thereby causing the voltage level of the detection spring 160 to be the first voltage level.

[0069] The substrate 200 includes a second pad 220, which is electrically connected to the detection spring 160. When a customer identification card is inserted into the card holder 100, the second pad 220 causes the detection spring 160 to have a second voltage level. For example, the second pad 220 may be electrically connected to the end of the fixing portion 162 of the detection spring 160 that is away from the top shell.

[0070] When the customer identification card is inserted into the card slot 100, the detection spring 160 separates from the connector 140, and the second pad 220 on the substrate 200 sets the voltage level of the detection spring 160 to the second voltage level. The voltage level of the second pad is equal to the voltage level of the detection spring. Since the detection spring has no other circuit connections besides the second pad, the voltage level of the second pad on the circuit board is high, therefore the voltage level of the detection spring is also high.

[0071] When the customer identification card is not inserted into the card slot 100, the detection spring 160 is electrically connected to the connector 140. The voltage level of the detection spring is affected not only by the circuit connected to the second pad on the circuit board, but also by the circuit connected to the connector, thus making the voltage level of the detection spring the first voltage level. For example, if the first pad is low or grounded, it can pull down the voltage levels of the connector and the detection spring that are electrically connected to it.

[0072] For example, the voltage of the first level can be lower than the voltage of the second level. For instance, the first level provided by the first pad 210 is a low level, such as less than 0.3V or 0.5V, while the second level provided by the second pad 220 is a high level, such as greater than 1.5V or greater than 3V. When the customer identification card is not inserted into the card slot 100, the detection spring 160 is electrically connected to the connector 140, and the level of the detection spring 160 is pulled low by the connector 140, which is electrically connected to the first pad 210. When the customer identification card is inserted into the card slot 100, the detection spring 160 is separated from the connector 140, and the level of the detection spring 160 is provided by the second pad 220, which is electrically connected to it.

[0073] Please combine Figure 16 , Figure 16 for Figure 12 The diagram shows a second structural representation of the circuit board in the electronic device. The circuit board 10 also includes a controller 300, which is mounted on the substrate 200. The controller 300 is electrically connected to the detection spring 160, and can determine whether the card holder 100 contains a customer identification card or not by detecting the voltage level of the detection spring 160.

[0074] The controller 300 can be a chip that identifies whether a customer identification card is present in the card slot 100. When the controller 300 detects whether a customer identification card is present or absent in the card slot 100, it can obtain the corresponding instruction and then send the instruction to other functional components such as a processor or modem. The controller 300 can also be a modem, which, after identifying whether a customer identification card is present in the card slot 100, can perform corresponding operations, such as mobile communication via the customer identification card.

[0075] Please combine Figure 17 , Figure 17 for Figure 12 The diagram shows a third structure of the circuit board in the electronic device. The circuit board 10 also includes an embedded customer identification chip 400 (Embedded-SIM, eSIM) disposed on the substrate 200, which is electrically connected to the controller 300. The controller 300 is also capable of controlling one of the customer identification card in the card holder 100 and the embedded customer identification chip 400 to work in conjunction with the controller 300.

[0076] eSIM embeds the traditional SIM card directly into the device's chip, rather than adding it as a separate removable component, eliminating the need for a physical SIM card. The controller 300 can control the customer identification card or embedded customer identification chip 400 within the card slot 100 to work in conjunction with the controller 300 as needed. The circuit board 10 simultaneously houses both the SIM card and the eSIM. If the user wants to communicate using the SIM card, the controller 300 can control communication via the SIM card; similarly, if the user wants to communicate using the eSIM, the controller 300 can control communication via the eSIM.

[0077] For example, the controller can be a modem. Both the SIM card and eSIM are electrically connected to the modem via a connection cable. The modem is electrically connected to the card slot and uses a detection spring in the card slot to determine whether a SIM card is inserted. If the modem determines through the detection spring that no SIM card is inserted, the modem works with the eSIM to communicate via the eSIM. If the modem determines through the detection spring that a SIM card is inserted, the modem works with the SIM card to communicate via the SIM card.

[0078] In another example, the controller can be a modem or a processor. The SIM card and eSIM are electrically connected to the modem via a switch. If the controller detects no SIM card inserted in the slot via a spring, it works in conjunction with the eSIM; that is, the controller controls the switch to electrically connect the modem to the eSIM, and communication is established via the eSIM. If the controller detects a SIM card inserted in the slot via the spring, it works in conjunction with the SIM; that is, the controller controls the switch to electrically connect the modem to the SIM, and communication is established via the SIM.

[0079] In another example, the controller can be a control switch. Both the SIM card and eSIM are connected to the modem via the controller. If the controller detects that no SIM card is inserted in the card slot via a detection spring, the controller works in conjunction with the eSIM, that is, the controller electrically connects the eSIM to the modem so that the modem can communicate via the eSIM. If the controller detects that a SIM card is inserted in the card slot via the detection spring, the controller works in conjunction with the SIM, that is, the controller electrically connects the SIM to the modem so that the modem can communicate via the SIM.

[0080] Please combine Figure 18 , Figure 18 for Figure 12 The diagram shows a fourth structure of the circuit board in the electronic device. The circuit board 10 may further include a pull-down resistor 260, one end of which is connected to the detection spring 160, and the other end is grounded. The detection spring 160 is grounded through the pull-down resistor 260, which stabilizes the voltage level of the detection spring 160. Adding the pull-down resistor 260 ensures that the voltage level tends to be stable, preventing the voltage level of the detection spring 160 from being directly pulled to ground.

[0081] The controller 300 may include a detection pin 320 and an input / output pin 340, both of which are electrically connected to the detection spring 160. When the controller 300 is started, it acquires the voltage level of the detection spring 160 through the detection pin 320 to determine whether a customer identification card is present in the card slot 100. The voltage level of the detection spring 160 can be one of a first voltage level and a second voltage level. For example, when no SIM card is inserted into the card slot 100, the voltage level of the detection spring 160 is low; when a SIM card is inserted into the card slot 100, the voltage level of the detection spring 160 is high. The specific method for determining whether a SIM card is present in the card slot 100 by the voltage level of the detection spring 160 can be found in the above embodiments and will not be repeated here. After the controller 300 is started, it outputs a preset voltage level through the input / output pin 340 to keep the detection pin 320 at the preset voltage level until the controller 300 restarts. The preset voltage level is the previously acquired voltage level of the detection spring 160.

[0082] When the electronic device powers on (or when the device starts up), input / output pin 340 does not output a level or is open-circuited. Detection pin 320 connects to detection spring 160 and uses the level of detection spring 160 to identify whether a SIM card is present in card slot 100. Then, it selects one of the two for communication: the SIM card or the eSIM. If a SIM card is present in card slot 100, it selects SIM card communication; otherwise, it selects eSIM communication. After the electronic device starts up, input / output pin 340 outputs a preset level to maintain the level of detection spring 160. At this time, the level of detection pin 320 is provided by input / output pin 340. Regardless of whether a SIM card is detected being inserted or removed, the level of detection pin 320 will not change. That is, it will not check whether a SIM card is inserted in card slot 100, and it will not affect the selection of SIM card or eSIM. In other words, after the electronic device selects one of the two for communication when it powers on, it will only select one again after the electronic device restarts.

[0083] Understandably, electronic devices can select between a SIM card and eSIM for communication upon power-on, maintaining this selection until the controller restarts. A controller restart can be achieved via a restart button. Controller restart can also be controlled remotely via an interface, allowing other devices to remotely control the electronic device and send a restart command. Upon receiving the command, the controller will restart. During the controller restart process, the power module and other components within the electronic device do not necessarily need to restart.

[0084] In some embodiments, the circuit board also includes a switch. The controller connects to the SIM card and eSIM via the switch. The switch is electrically connected to a detection spring, and the switch can select either the SIM card or the eSIM to communicate with the controller based on the voltage level of the detection spring. When the circuit board is powered on, the detection spring outputs different voltage levels depending on whether a SIM card is inserted in the card slot. The switch selects either the SIM card or the eSIM to communicate with the controller based on the voltage level of the detection spring. For example, when a SIM card is in the card slot, the switch selects the SIM card to communicate with the controller; when no SIM card is inserted, the switch selects the eSIM to communicate with the controller. Input / output pins are also electrically connected to the switch. After the switch selects a SIM card, the input / output pins provide a stable voltage level to the switch, maintaining the switch in its current state. Whether a SIM card is subsequently inserted into the card slot or removed from the card slot will not affect the operation of the switch.

[0085] A connection interface can be reserved on the circuit board corresponding to the detection spring, which can be used for functional expansion. For example, this interface can be connected to the GPIO of other functional components or the input of a trigger to determine whether a SIM card is inserted into the card slot. The interface can also be connected to an analog-to-digital converter (ADC) to obtain the accurate voltage level of the detection spring. The interface can also be connected to other functional circuits, which are electrically connected to the detection spring. The functional circuit can be selected as needed, such as a delay circuit, a voltage regulator circuit, or a filter circuit. The delay circuit can be used by other functional components to delay the acquisition of the detection spring's voltage level; the voltage regulator circuit can be used to stabilize the voltage level of the detection spring, such as making the voltage change curve of the detection spring closer to a square wave; and the filter circuit can filter out some interference signals. It should be noted that this interface can be connected to one or more functional components or functional circuits. This application does not limit the functional components or functional circuits connected to the interface.

[0086] It should be noted that the card holder in any of the above embodiments may further include multiple data conductive elements. These multiple data conductive elements are mounted on a bracket, soldered to pads on the substrate via corresponding soldering ends, and electrically connected to pins on the SIM card via corresponding contacts, thereby enabling data interaction between the SIM card and the modem. After the top cover of the card holder is installed on the card holder, it is also electrically connected to multiple grounding pads on the substrate; that is, the top cover can serve as the overall ground of the circuit board.

[0087] Electronic devices can be customer pre-installed equipment (CPE), mobile terminal devices such as mobile phones and tablets, or devices that communicate via SIM cards, such as gaming devices, augmented reality (AR) devices, virtual reality (VR) devices, in-vehicle computers, laptops, data storage devices, audio playback devices, video playback devices, and wearable devices. Wearable devices can include smart bracelets, smart glasses, etc.

[0088] Among them, the customer front-end device is a mobile signal access device that receives mobile signals and forwards them as wireless WIFI signals. The customer front-end device is also a device that converts high-speed 4G or 5G signals into WiFi signals and can support multiple mobile terminals to access the Internet at the same time.

[0089] Please continue reading. Figure 12The electronic device 1 can be a Customer Premise Equipment (CPE), or other devices, without specific limitations. The Customer Premise Equipment 1 is used to implement network access functionality, converting the operator's public network (WAN) to the user's home local area network (LAN). Current internet broadband access methods can be categorized as FTTH (Fiber to the Home), DSL (Digital Telephone Line), Cable (Cable TV Line), and Mobile (i.e., wireless CPE). The Customer Premise Equipment 1 is also a mobile signal access device that receives mobile signals and forwards them as wireless Wi-Fi signals. It can convert 4G or 5G signals into Wi-Fi signals, supporting multiple terminal devices such as mobile phones and tablets to access the network.

[0090] In one embodiment, the customer front-end device 1 includes a housing 12, a circuit board (not shown), and an radio frequency (RF) system disposed on the housing 12, the RF system being electrically connected to the circuit board. The housing 12 forms a mounting cavity, in which the circuit board and the RF system are mounted, and the housing 12 provides support, positioning, and protection. Figure 12 In the illustrated embodiment, the housing 12 is generally cylindrical, and the appearance of the customer front-end device 1 is primarily represented by the housing 12. In other embodiments, the housing 12 may have other shapes, such as prisms. The circuit board may have multiple interfaces 13 exposed to the housing 12, and these interfaces 13 are electrically connected to the circuit board. Figure 12In the illustrated embodiment, interface 13 includes a power interface 131, a USB interface 133, a network cable interface 135, and a telephone interface 136. The power interface 131 is used to connect to an external power source to power the customer front-end device 1. The USB interface 133 is used for data transmission between the customer front-end device 1 and external devices. The telephone interface 136 is used to connect an external landline telephone. Of course, the USB interface 133 and the power interface 131 can be integrated into one unit to simplify the layout of interface 13 on the customer front-end device 1. The network cable interface 135 may further include a wired network access port and a wired network output port. The customer front-end device 1 can connect to the network through the wired network access port and then connect to other devices through one or more wired network output ports. Of course, in some embodiments, the network cable interface 135 and the telephone interface 136 can be integrated into one unit to simplify the layout of interface 13 on the customer front-end device 1. Of course, in some implementations, the wired network output can be omitted. That is, after the customer front-end device 1 connects to the network using a wired network input, it uses a radio frequency system to convert the wired network into a wireless network (e.g., WiFi) for external devices to access the network. Alternatively, both the wired network input and output can be omitted. In this implementation, the customer front-end device 1 can connect to a cellular network (also known as a mobile network) via a radio frequency system and then convert it into a WiFi signal for external devices to access the network. The circuit board can also have a card slot 100 exposed to the housing 12, which can be used for users to insert and remove SIM cards.
