[0033] At present, most of the general circuit board systems include a main chip and a memory chip, in which the main chip is used as a central processing unit to execute instructions, and the memory chip stores software instructions and data. Generally, when a circuit motherboard system is powered on for the first time for debugging, engineers need to first burn the software instructions and data to the memory chip through a burner, then solder the memory chip to the circuit motherboard, and then power on the circuit motherboard so that the circuit motherboard system can work normally. In this process, if there is a problem with the software instructions and data, the motherboard system cannot work normally. At this time, the memory chip needs to be unsoldered from the circuit motherboard, and then the updated software instructions and data are burned again with a burner, and then the memory chip is re-soldered to the circuit motherboard. If there is a problem again, the above actions need to be repeated. In the process of designing and developing the circuit motherboard, this problem of repeatedly soldering the memory chip often occurs. The process of repeatedly soldering the memory chip not only increases the workload of engineers and affects work efficiency, but also may damage the circuit motherboard.

[0034] To this end, the utility model provides a memory chip holder for debugging, which can allow the memory chip to be disassembled and assembled multiple times for testing without repeated welding.

[0035] Reference Figures 1 to 4According to an embodiment of the utility model, a debugging memory chip seat includes a mounting portion and an elastic connection portion, wherein the mounting portion is configured as a structure for detachably connecting the memory chip, so that the memory chip can be repeatedly disassembled and assembled on the mounting portion. The elastic connection portion is arranged on the peripheral side of the mounting portion, and the elastic connection portion is configured as a structure for detachably connecting the circuit main board, and is used to elastically press the mounting portion onto the circuit main board, and realize the electrical connection between the memory chip and the circuit main board. The elastic connection portion can realize the detachable installation of the mounting plate on the circuit main board by detachably connecting the circuit main board. When testing and debugging are required, it is only necessary to install the elastic connection portion on the circuit main board so that the mounting portion is in the chip installation position on the circuit main board, and then install the memory chip on the mounting portion to realize the solder-free connection between the memory chip and the circuit main board. When debugging finds that there is a problem with the burning content and needs to be re-burned, the memory chip can be removed from the mounting portion and re-burned, or the entire debugging memory chip seat can be removed and the memory chip can be taken out for burning. The elastic connection portion elastically presses the mounting portion onto the circuit main board, which can effectively ensure the stable connection between the memory chip and the circuit main board, while avoiding damage to the pins.

[0036] Therefore, the debugging memory chip seat in the utility model utilizes the mounting portion to detachably fix the memory chip, and presses the mounting portion onto the circuit main board through the elastic connecting portion, so as to realize the electrical connection between the memory chip and the circuit main board, and the memory chip can be tested. When the memory chip needs to be re-burned, it is only necessary to remove the memory chip from the mounting portion, and then install it into the mounting portion again after burning, without the need for welding, which can effectively improve work efficiency, effectively avoid the workload of repeated welding and avoid possible damage to the circuit main board, and greatly facilitate the debugging and research and development work of the circuit main board system.

[0037] Reference Figure 1In some embodiments of the utility model, the elastic connection part includes an annular support and an elastic member 106, the annular support is arranged on the peripheral side of the mounting part, and the annular support is provided with an adjustment guide rod around the mounting part. One end of the elastic member 106 is connected to the adjustment guide rod, and the other end is provided with a hook 1061, and the hook 1061 is configured as a structure that can clamp the edge of the circuit main board, so as to be hung on the edge position of the circuit main board. The elastic member 106 can be moved and adjusted along the length direction of the adjustment guide rod. With the structural setting of this embodiment, the annular support can be used to install the elastic member 106, so that the circumferential force of the mounting part is uniformly and stably fixed on the circuit main board. The elastic member 106 and the circuit main board are hung by the hook 1061, which is convenient for disassembly and assembly. The elastic member 106 can be moved and adjusted along the adjustment guide rod, which is convenient for adjusting the relative angle between the elastic member 106 and the mounting part, thereby changing the position and angle between the mounting part and the circuit main board, and ensuring that the storage chip is in the installation position on the circuit main board. It can be understood that the elastic member 106 can be wound around the adjustment guide rod to ensure that the circumferential force of the mounting portion is uniform.

[0038] Specifically, refer to Figure 1 In some embodiments of the present invention, the annular support member includes a ring body 101, and the annular support member forms an adjustment guide rod through the ring body 101. In this embodiment, by setting the annular support member as a ring structure, it is convenient for the elastic member 106 to move and adjust to change the angular orientation of the mounting portion, and it is also beneficial to ensure that the circumferential force of the mounting portion is uniform.

With the structural setting of this embodiment, one end of the elastic member 106 is hooked to the edge of the circuit main board, and the other end is hooked to the adjustment guide rod, which is convenient to install and has a simple structure. The elastic deformation of the connecting section 1062 can apply an elastic pressing force to the mounting portion toward the circuit main board to ensure the docking of the storage chip with the circuit main board.

[0042] Furthermore, the surfaces of the hook 1061 and the hook 1063 are both provided with an insulating layer to avoid short circuit. It is understandable that the connecting section 1062 and the annular body 101 may also adopt an insulating structure.
