[0019] Hereinafter, embodiments will be described with reference to the accompanying drawings, which are not intended to limit the disclosure described in the claims.
[0020] Please see Figure 1 and Figure 2 The following is combined with Figure 1 and Figure 2 A detailed description is provided of a card insertion redundancy fixing device provided in the embodiments of this application.
[0021] This application provides a card insertion redundancy fixing device, such as Figure 1 and Figure 2 As shown, specifically, the card insertion redundancy fixing device includes a circuit board body 1 and a fixing component disposed on the circuit board body 1; wherein, the fixing component includes a first fixing member 2 and a second fixing member 3, the first fixing member 2 is located inside the circuit board body 1 and is disposed on the side close to the circuit board body 1; the second fixing member 3 is disposed on the side of the circuit board body 1, the connecting end of the second fixing member 3 is connected to the side of the circuit board body 1, and the fixing end of the second fixing member 3 extends in a direction away from the circuit board body 1, and when the card to be inserted 4 is inserted into the circuit board body 1, the side of the fixing end of the second fixing member 3 abuts against the card to be inserted 4.
[0022] In this embodiment of the application, the first fixing member 2 and the second fixing member 3 are both used to fix the card to be inserted 4. Thus, by using the first fixing member 2 and the second fixing member 3, redundant fixing of the card to be inserted 4 can be achieved, thereby preventing the card from popping out of the card slot due to vibration and affecting the normal use of the device, thus improving the stability and reliability of the card insertion. Furthermore, the first fixing member 2 and the second fixing member 3 will not affect the insertion and removal of the card to be inserted 4, and facilitate the disassembly of the card to be inserted 4.
[0023] In one specific embodiment, the first fixing member 2 is used to provide basic fixation for the card to be inserted 4. Specifically, the first fixing member 2 is used to fix the card to be inserted 4 inside the circuit board body 1. The first fixing member 2 can realize the self-locking function of the card to be inserted 4. The second fixing member 3 is used to provide redundant fixation for the card to be inserted 4. When the card to be inserted 4 is inserted into the circuit board body 1, the first fixing member 2 provides basic fixation for the card to be inserted 4, and the side of the fixing end of the second fixing member 3 abuts against the card to be inserted 4, thereby realizing redundant fixation for the card to be inserted 4 and improving the stability and reliability of the card insertion.
[0024] In practical applications, the circuit board body 1 can be a PCB board or other circuit board, and the card to be inserted 4 can be a memory card. For example, the card to be inserted 4 can be a SIM card, TF card or SD card.
[0025] It should be noted that the card insertion redundancy fixing device is located inside the whole machine, so the card to be inserted 4 will not be ejected from the card slot in the circuit board body 1 by accidentally pressing the fixing end of the second fixing member 3.
[0026] In one alternative implementation, such as Figure 1 As shown, the second fixing member 3 includes an elastic fixing member 31 and a fixing structure 32; wherein, the connecting end of the elastic fixing member 31 is fixedly connected to the side of the circuit board body 1, and the fixing structure 32 is provided on the side of the fixing end of the elastic fixing member 31. When the card to be inserted 4 is inserted into the circuit board body 1, the side of the fixing structure 32 away from the elastic fixing member 31 abuts against the card to be inserted 4.
[0027] In this embodiment, the elastic fastener 31 is a deformable structure. Specifically, the elastic fastener 31 can be deformed by pressing the fixed end of the elastic fastener 31. When the pressure is released, the elastic fastener 31 can return to its original shape. For example, the material of the elastic fastener 31 can be metal or plastic, etc. The shape of the elastic fastener 31 is a sheet structure. In one embodiment, when the card to be inserted 4 is inserted into the circuit board body 1, the fixing structure 32 can abut against the card to be inserted 4. In this way, the fixing structure 32 can block the card to be inserted 4, thereby preventing the card from popping out of the card slot due to vibration and ensuring the stable operation of the electronic device.
[0028] In one specific embodiment, the fixed end of the elastic fastener 31 can be bent toward the direction of the circuit board body 1 under the action of pressure. Specifically, when the fixed end of the elastic fastener 31 is pressed, the elastic fastener 31 drives the fixing structure 32 to tilt and move toward the direction of the circuit board body 1.
[0029] In this embodiment, when the fixed end of the elastic fastener 31 is pressed, the fixed end of the elastic fastener 31 is not connected to the side of the circuit board body 1. The fixed end of the elastic fastener 31 can be bent toward the direction close to the circuit board body 1, thereby driving the fixing structure 32 to move toward the direction close to the circuit board body 1. The fixing structure 32 tilts toward the direction close to the circuit board body 1. It can be understood that the non-contact surface between the fixing structure 32 and the elastic fastener 31 is an inclined surface. Thus, when the fixing structure 32 moves toward the direction close to the circuit board body 1, it tilts to one side, thereby leaving space for card insertion. This avoids the fixing structure 32 blocking the card 4 to be inserted into the card slot. After the card 4 to be inserted is inserted into the card slot and the elastic fastener 31 returns to its original state, it can drive the fixing structure 32 to move to a position that abuts against the card 4 to be inserted, thereby preventing the card 4 to be inserted from being removed from the card slot.
[0030] In one specific embodiment, when it is necessary to remove the card to be inserted 4, the fixing end of the elastic fixing member 31 can be pressed, thereby causing the fixing structure 32 to tilt to one side, leaving space for the card removal operation. It should be noted that when the fixing end of the elastic fixing member 31 is pressed to drive the fixing structure 32 to tilt to one side, the fixing structure 32 can also squeeze the card to be inserted 4, thereby releasing the self-locking process of the first fixing member 2 on the card to be inserted 4, and thus the card to be inserted 4 can be removed. Therefore, the fixing structure 32 is set without affecting the insertion and removal of the card to be inserted 4, and the operation process is relatively simple. While improving stability, it can also improve the convenience of operation.
[0031] In one specific embodiment, the connection between the fixing structure 32 and the side of the fixing end of the elastic fastener 31 can be welding or bonding.
[0032] In this embodiment, the fixing structure 32 is a device without signal attributes, which is only used for fixing. In one specific embodiment, the thickness of the fixing structure 32 is any value between 1mm and 4mm. Preferably, the thickness of the fixing structure 32 is any value between 2mm and 3mm. For example, the thickness of the fixing structure 32 is 2mm, 2.5mm, 2.8mm and 3mm. In one specific implementation, the fixing structure 32 is a surface mount capacitor or a surface mount diode. Since surface mount capacitors or surface mount diodes have lower costs, the production cost of the card redundancy fixing device can be reduced.
[0033] In one alternative implementation, such as Figure 1 and Figure 2 As shown, the circuit board body 1 is provided with a rectangular slot 11. The rectangular slot 11 is located near the side of the circuit board body 1, and the side of the rectangular slot 11 is exposed. The rectangular slot 11 is provided with a first fixing member 2.
[0034] In this embodiment, the rectangular card slot 11 is used to match the card 4 to be inserted, and a first fixing member 2 is provided in the rectangular card slot 11. The card 4 to be inserted can be fixed in the rectangular card slot 11 by the first fixing member 2. When the card 4 to be inserted is inserted into the rectangular card slot 11, the side of the fixing end of the second fixing member 3 abuts against the card 4 to be inserted, thereby achieving redundant fixing of the card 4 to be inserted. This can prevent the inserted card from popping out of the card slot due to vibration, which would affect the normal use of the device, and improve the stability and reliability of the inserted card.
[0035] In one alternative implementation, such as Figure 2 As shown, the first fixing member 2 includes a locking rod 21, a guide structure 22, a reset member 23, and a locking part 24; wherein, one end of the locking rod 21 is fixedly connected to the inner side of the rectangular slot 11, the other end of the locking rod 21 moves along the guide structure 22, the guide structure 22 is slidably connected to the rectangular slot 11, one end of the reset member 23 is fixedly connected to the inner side of the rectangular slot 11, the other end of the reset member 23 is connected to the guide structure 22, and the locking part 24 is fixedly connected to the guide structure 22.
[0036] In this embodiment, one end of the locking rod 21 is used to match the guide structure 22. Specifically, during the process of inserting or removing a card, one end of the locking rod 21 can move according to the guide groove in the guide structure 22. The locking part 24 is used to match the card slot on the card to be inserted 4, thereby locking the card to be inserted 4. The reset member 23 is used to eject the card to be inserted 4. For example, the reset member 23 can be a reset spring.
[0037] In practical applications, the locking part 24 is linked with the guide structure 22. That is, when the guide structure 22 slides relative to the rectangular card slot 11, the guide structure 22 can carry the locking part 24 to move until the locking part 24 matches the card slot on the card to be inserted 4.
[0038] In one specific embodiment, the guide structure 22 includes a first guide groove and a second guide groove, and there is a guide step between the first guide groove and the second guide groove.
[0039] In this embodiment, the guide step is used to limit the movement trajectory of one end of the locking rod 21. When the card to be inserted 4 is inserted, one end of the locking rod 21 can move strictly according to the guide trajectory of the first guide groove. When one end of the locking rod 21 moves to the connection between the first guide groove and the second guide groove, the card to be inserted 4 can be locked. When the card to be inserted 4 is removed, one end of the locking rod 21 can move strictly according to the guide trajectory of the second guide groove. When one end of the locking rod 21 moves out of the second guide groove, the card to be inserted 4 can be unlocked.
[0040] It should be noted that a guide step is also provided in the first guide groove. The guide step in the first guide groove can restrict one end of the locking rod 21 from moving according to the guide trajectory of the first guide groove during the insertion process, thereby ensuring the stability of the lock.
[0041] In one specific implementation, the depth of the first guide groove is different from the depth of the second guide groove.
[0042] In this embodiment, the depth of the first guide groove is greater than the depth of the second guide groove. Therefore, when the card to be inserted 4 is inserted, due to the obstruction of the second guide groove, one end of the locking rod 21 will not move according to the guide trajectory of the second guide groove, thereby ensuring the stability of the locking.
[0043] In practical applications, when it is necessary to insert the card 4, the fixed end of the elastic fixing member 31 can be pressed, thereby tilting the fixing structure 32 to one side to leave space for the card insertion operation. During the insertion of the card 4, the card 4 pushes the guide structure 22 to move in the direction of the locking rod 21. At this time, one end of the locking rod 21 moves according to the guide trajectory of the first guide groove. After the insertion is completed, one end of the locking rod 21 moves to the groove where the first guide groove and the second guide groove are connected. Since the reset member 23 is connected to the guide structure 22, but one end of the locking rod 21 is located in the groove, the reset member 23 cannot be reset. At this time, the card slot of the card 4 matches the locking part 24, and the card 4 is in a fully inserted state.
[0044] Furthermore, when it is necessary to remove the card to be inserted 4, the fixed end of the elastic fixing member 31 can be pressed, thereby tilting the fixing structure 32 to one side to leave space for card removal. The tilting movement of the fixing structure 32 can drive the card to be inserted 4 to move towards the inside of the rectangular card slot 11. At this time, one end of the locking rod 21 moves according to the guide trajectory of the second guide groove. The locking part 24 and the guide structure 22 are reset to the initial position under the action of the reset member 23, thereby realizing the removal of the card to be inserted 4.
[0045] The above embodiments of this application have the following beneficial effects: This application provides a first fixing member and a second fixing member. The first fixing member is located inside the circuit board body and is positioned on the side closest to the circuit board body. The second fixing member is positioned on the side of the circuit board body, with its connecting end connected to the side of the circuit board body and its fixing end extending away from the circuit board body. When a card to be inserted is inserted into the circuit board body, the side of the fixing end of the second fixing member abuts against the card. Thus, the first and second fixing members can redundantly fix the card, preventing the card from popping out of the card slot due to vibration and affecting the normal use of the device, thereby improving the stability and reliability of the inserted card.
