Description

Technical Field

[0001] The utility model relates to the technical field of memory chip modules, and more particularly to an assembly structure based on a micro-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 an assembly structure based on a micro-compressed solid-state storage hard disk module, which can be applied to miniaturized devices such as Mini PCs, thin and light notebooks, tablets, all-in-one computers, game consoles, etc., and can identify the interface type of the micro-compressed solid-state storage hard disk module, thereby improving strength and reducing costs.

The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0023] Reference Figure 1-3As shown, the utility model discloses an assembly structure based on a micro-compressed solid-state storage hard disk module, and the assembly structure based on the micro-compressed solid-state storage hard disk module includes a PCB mainboard 1, a connector 2 and an application-end PCB circuit board 3; the connector 2 is fixedly installed between the PCB mainboard 1 and the application-end PCB circuit board 3; the connector 2 includes a rubber core 9, a reinforcing rib 12, a first positioning column 10, a second positioning column 11 and a spring pin 8; the reinforcing rib 12 is welded to both sides of the rubber core 9; the first positioning column 10 and the second positioning column 11 are respectively fixedly installed at the corners of the reinforcing rib 12, and the size of the first positioning column 10 is slightly smaller than / slightly larger than the size of the second positioning column 11; the spring pin 8 is fixedly installed on the top of the rubber core 9 and contacts with the PCB mainboard 1.

[0024] It should be noted that, in this embodiment, the PCB mainboard 1 serves as the basic structure of the micro-compressed solid-state storage hard disk module, and is used to provide circuit connection and mechanical support for the entire micro-compressed solid-state storage hard disk module; the connector 2 serves as a bridge connecting the PCB mainboard 1 and the application-end PCB circuit board 3 to ensure electrical connection between the two. Specifically, the connector 2 includes a rubber core 9, a reinforcing rib 12, a first positioning column 10, a second positioning column 11 and a spring pin 8, wherein the rubber core 9 serves as the main structure of the connector 2, and is used to provide structural support for the arrangement of the reinforcing rib 12, the first positioning column 10, the second positioning column 11 and the spring pin 8; the reinforcing rib 12 is used to enhance the strength of the connector 2 to avoid damage caused by vibration or impact during use.
