Description

Technical Field

[0001] This utility model belongs to the field of user identification cards, and in particular relates to an electronic device. Background Technology

[0002] Currently, cellular devices with built-in data SIM cards (such as 4G / 5G CPE, MiFi, UFi, etc.) use surface-mount SIM cards, which are standard VQFN48 (ultra-thin, four-sided pinless flat) packages, measuring 5x6mm. As an SMT component, once a SIM card becomes unusable (e.g., due to physical damage, card cancellation, or card expiration), it can only be replaced by manually soldering the surface-mount SIM card after disassembling the device. This replacement process is cumbersome and costly, resulting in poor replaceability. Disassembling and replacing a surface-mount SIM card requires soldering the device's motherboard, followed by retesting, which is time-consuming and costly, thus reducing replacement efficiency. Utility Model Content

[0026] In one embodiment of this utility model, the built-in patch-type user identification card is a patch-type SIM card or a patch-type USIM card.

[0027] In one embodiment of this utility model, the first connector 105 is a female connector, and the second connector 106 is a male connector. The first and second connectors can be male and female pin headers, or they can be other types such as wafers or USB interfaces.

[0028] In one embodiment of this utility model, the electronic device is a portable Wi-Fi device.

[0029] In one embodiment of this utility model, the portable Wi-Fi device is a MiFi device, a UFi device, or a CPE device.

[0030] During production, the built-in surface-mount user identification cards (such as SIM cards or USIM cards) are pre-soldered onto the card board using SMT (Surface Mount Technology), and then connected to the motherboard's first connector via a pluggable second connector. When the built-in surface-mount user identification card is damaged and needs to be replaced, simply remove the card board and directly insert the pre-made, batch-produced new card board into the motherboard's first connector via the card board's second connector.

[0031] In this embodiment of the utility model, the built-in patch-type user identification card is soldered onto the card board and connected to the first connector of the motherboard through a pluggable second connector. When the built-in patch-type user identification card needs to be replaced, a new card board that has been pre-made in batches can be directly replaced without manual soldering and testing, saving time and improving card replacement efficiency.

[0032] Figure 2 A structural diagram of another electronic device is provided, which includes a motherboard and a cardboard.

[0033] The motherboard includes a main control module 201, a first switch 202, a second switch 203, a third switch 205, a fourth switch 207, a first connector 206, an external card slot 204, and multiple built-in surface mount user identification cards 208. The main control module 201 is connected to the first switch 202, the third switch 205, and the fourth switch 207. The first switch 202 is connected to the second switch 203 and the external card slot 204. The second switch 203 is connected to the third switch 205 and the fourth switch 207. The third switch 205 is connected to the first connector 206. The fourth switch 207 is connected to the multiple built-in surface mount user identification cards 208.

[0034] The card board includes a second connector 209 and a plurality of built-in patch-type user identification cards 210 connected to the second connector 209. The second connector 209 of the card board is connected to the first connector 206 of the motherboard.

[0037] In another embodiment of this utility model, the electronic device is a portable Wi-Fi device.

[0038] In another embodiment of this utility model, the portable Wi-Fi device is a MiFi device, a UFi device, or a CPE device.

[0039] During production, the built-in surface-mount user identification card (such as a SIM card or USIM card) is directly soldered onto the motherboard. When the built-in surface-mount user identification card is damaged or malfunctions, it is not necessary to remove it from the motherboard. Instead, the second connector of a pre-made card board (pre-fabricated by STM) is connected to the first connector on the motherboard, with a new built-in surface-mount user identification card soldered onto the card board. After the card board is inserted, the main control module automatically switches the second switch to the third switch, prioritizing the use of the built-in surface-mount user identification card on the card board.

[0040] In this embodiment of the utility model, both the motherboard and the card board have built-in surface-mount user identification cards soldered on. When the original built-in surface-mount user identification card on the motherboard malfunctions and cannot be used, the card board is inserted. The card board and the motherboard are connected by a pluggable first connector and a second connector. When the card board is inserted, the second switching switch is automatically switched to the third switching switch. That is, the card board does not require the main control module to control it. After the card board is inserted, the hardware automatically prioritizes the use of the built-in surface-mount user identification card on the card board.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
