Description

Technical Field

[0001] The utility model relates to the technical field of memory chip modules, and more particularly to a board-to-board connector for a dual-bit compressed solid-state storage hard disk module. Background Art

[0002] The three common module connection and assembly methods are embedded welding, connector slots, and board-to-board pin connections.

[0003] 1. Embedded welding: refers to assembly onto the device by welding, such as eMMC and UFS. The advantage is that it is small and light, but the disadvantage is that it is inconvenient to upgrade and replace;

[0004] 2. The connector slot is connected by a spring connector and fixed by screws and other structures, such as conventional memory modules and M.2 interface solid-state drives. The advantage is that upgrades and replacements are simple, but the spring pin structure and material limitations, such as defects in conductivity, length, impedance, and shielding protection, cannot meet the needs of higher frequency applications. The connector structure also takes up space, limiting the application of lightweight and thin applications. Small size and high density also weaken the seismic stability of micro storage hard drive modules, making them unable to meet the needs of next-generation technologies.

[0005] 3. Board-to-board pin connections were first used in CPUs, using tiny, high-precision spring pins. Due to their short size and highly consistent design, they are particularly well-suited for high-frequency applications. Memory modules were the first to adopt board-to-board pin connections, resulting in the LPCAMM2 (Low Power DDRV CAMM2 module) and CAMM2 (Compression Attached Memory Module). However, board-to-board pin connections are still in the exploratory stage in the flash memory storage field, and standardized modules, connectors, and other peripheral accessories for board-to-board pin connections have yet to be established.

[0006] In this regard, the utility model provides a dual-position assembly structure based on an expandable and compressed solid-state storage hard disk module, which can be applied to medium and large devices such as desktop computers, workstation servers, laptops, multimedia billboards, network terminals, etc., and can identify the interface type of the expandable and compressed solid-state storage hard disk module, expand the capacity, and optimize the user experience.

[0024] It should be noted that, in this embodiment, the first PCB main board 1 and the second PCB main board 2 are the main structures of two expandable compressed solid-state storage hard disk modules connected to the connector 3, which are used to provide mechanical support and electrical connection for the expandable compressed solid-state storage hard disk module; the connector 3 serves as a bridge connecting the first PCB main board 1, the second PCB main board 2 and the application-end PCB circuit board 4 to ensure the electrical connection between the three. Specifically, the connector 3 includes a first connecting body and a second connector body 7. The first connector body 6 is used to connect the first PCB main board 1 and the application-end PCB circuit board 4; the second connector body 7 is used to connect the second PCB main board 2 and the application-end PCB circuit board 4; further, the first connector body 6 and the second connector body 7 are both provided with a spring pin 10, a first positioning column 8 and a second positioning column 9. The design of the first positioning column 8 and the second positioning column 9 is used to identify the interface type of the expandable compressed solid-state storage hard disk module; the spring pin 10 contacts the first PCB main board 1 / the second PCB main board 2 to realize the first P The board-to-board pin connection method between the CB mainboard 1 / the second PCB mainboard 2 and the application-end PCB circuit board 4 is suitable for high-frequency products; the application-end PCB circuit board 4 is used to connect to a specific application device to complete data input and output; when the present invention is implemented, the connector 3 contacts the first PCB mainboard 1 / the second PCB mainboard 2 through the spring pin 10 to realize the board-to-board pin connection method between the two, which is more suitable for high-frequency products, and thus can be applied to medium and large devices such as desktop computers, workstation servers, notebook computers, multimedia billboards, network terminals, etc.; the dual-position connection design is adopted, which can realize that an application-end PCB circuit board 4 can be connected to two expandable compressed solid-state storage hard disk modules at the same time. Under the premise that the expandable compressed solid-state storage hard disk module itself has scalability, the number of installation of expandable compressed solid-state storage hard disk modules is increased, which can further expand the expansion capacity of the application end to meet user needs and optimize user experience; the interface type of the micro-compressed solid-state storage hard disk module is identified by the difference in size of the first positioning column 8 and the second positioning column 9, so as to meet the needs of users and optimize user experience. Taking the I ex4 protocol interface and the SATA protocol interface as examples, if the size of the first positioning post 8 is slightly larger than the size of the second positioning post 9, the interface type of the micro-compression solid-state storage hard disk module is a PC I ex4 protocol interface. If the size of the first positioning post 8 is slightly smaller than the size of the second positioning post 9, the interface type of the micro-compression solid-state storage hard disk module is a SATA protocol interface.

[0025] Reference Figure 1As shown, the dual-position assembly structure based on the expandable compressed solid-state storage hard disk module also includes a fixing bolt, and the first connector body 6 and the second connector body 7 are both provided with a fixing hole 11, and the fixing hole 11 is located on both sides of the spring pin 10; the fixing bolt passes through the fixing hole 11 and the first PCB main board 1 / the second PCB main board 2.

[0026] It should be noted that, in this embodiment, the design of the fixing holes 11 and the fixing bolts can fix the first PCB main board 1 / the second PCB main board 2, the connector 3 and the application-end PCB circuit board 4 to ensure the stability of the assembly structure.

[0027] Reference Figure 1 and Figure 3 As shown, the first connector body 6 and the second connector body 7 are further fixedly mounted with reinforcement welding feet 5 , and the reinforcement welding feet 5 are located outside the fixing holes 11 .

[0028] It should be noted that, in this embodiment, the reinforcing solder feet 5 are designed to reinforce the assembly between the connector 3 and the application-end PCB circuit board 4 .

[0029] Reference Figure 3 As shown, a solder ball matrix 15 is provided at the bottom of the first connector body 6 and the bottom of the second connector 3 , and the solder ball matrix 15 is soldered to the application-end PCB circuit board 4 .

[0030] It should be noted that, in this embodiment, the solder ball matrix 15 is designed to achieve electrical connection between the connector 3 and the application-end PCB circuit board 4, and further achieve electrical connection between the first PCB main board 1 and the second PCB main board 2.

[0031] Continue to refer to Figure 3 As shown, a third positioning column 13 and a fourth positioning column 14 are provided between the first connector body 6 and the second connector body 7. The third positioning column 13 and the fourth positioning column 14 are respectively located on both sides of the bottom of the connector 3, and the size of the third positioning column 13 is slightly smaller than that of the fourth positioning column 14.

[0032] It should be noted that, in this embodiment, the design of the third positioning column 13 and the fourth positioning column 14 can facilitate the precise assembly of the connector 3 and the application end PCB circuit board 4.

[0034] It should be noted that, in this embodiment, the design of the rectangular hollow 12 and the capacitor allows the capacitor to be directly connected to the power circuit. This layout reduces the distance between the connector 3 and the power supply, thereby reducing the inductance and resistance and improving the response speed of the power supply.

[0036] It should be noted that, in this embodiment, the circular pad matrix is ​​designed to adapt to the distribution of the spring pins 10 on the connector 3, so as to realize the point-to-point connection between the circular pad matrix and the spring pins 10, and the board-to-board pin connection between the PCB mainboard and the connector 3, thereby realizing the data transmission between the first PCB mainboard 1 / the second PCB mainboard 2 and the application end PCB circuit board 4.

[0037] It should also be noted that the spring pin 10 is C-shaped, and the part protruding from the top has deformable elastic force. The convex point stamped on the top contacts the circular pad matrix contact at the bottom of the expandable and compressed solid-state storage hard disk module to connect the circuit; the middle part of the spring pin 10 is slightly wider, and the two sides are clamped in the first connector body 6 / second connector body 7 to fix the spring pin 10; the bottom of the spring pin 10 is stamped and bent into a circular sheet for implanting solder balls for welding. The solder balls slightly protrude from the bottom surface of the first connector body 6 / second connector body 7 to improve the welding yield. After welding, the solder balls melt and solidify, and will be the same height as the bottom surface of the first connector body 6 / second connector body 7. The bottom surface of the first connector body 6 / second connector body 7 is completely consistent with the application end PCB circuit board 4. In addition, the spring pin 10 is installed at a 45° angle. The principle of longer diagonal angles is used to extend the force arm length of the spring pin 10, improve the elasticity of the spring pin 10, and secondly maximize the volume of the spring pin 10 to reduce the manufacturing difficulty.
