Micro-rectangular J29A interface intelligent power supply protection three-proofing industrial solid state drive

Abstract

The invention discloses a micro-rectangular J29A interface intelligent power supply protection three-proofing industrial solid state drive, which comprises a shell and a circuit board, wherein the shell comprises an aluminum alloy upper cover and an aluminum alloy lower cover; AB glue is added between the shell and the circuit board; the aluminum alloy lower cover is provided with a mounting cavity; the circuit board is mounted in the mounting cavity; the circuit board is provided with a micro-rectangular J29A stranded wire type interface, a power-off protection chip, a central processing unit, a crystal oscillator, a temperature sensing chip, a filtering circuit, a power supply chip, a flash memory module and a built-in intelligent power supply module; according to the micro-rectangular J29A interface intelligent power supply protection three-proofing industrial solid state drive in the invention, the stranded wire type elastic pin is adopted, so that the contact reliability is high,and hot plugging is supported; normally, when a memory disk is replaced or taken down, the user needs to close the system; however, the hard disk can be directly taken out by using the hot plugging technology, and the system can still run normally and uninterruptedly, so that the usability and the application to specific removal occasions are improved.

Description

technical field [0001] The invention discloses a micro-rectangular J29A interface intelligent power supply to protect the three-proof industrial solid-state hard disk. Background technique [0002] Solid State Drives (Solid State Drives) are hard disks made of solid-state electronic memory chip arrays. They are composed of control units and storage units (FLASH chips, DRAM chips). They have fast reading and writing, light weight, and The characteristics of low energy consumption and small size make it popular rapidly. According to relevant statistics, shipments in 2015 increased by 25.8% to 102.78 million pieces. The trend of gradually replacing traditional mechanical hard drives is obvious. However, ordinary solid-state drives have many defects. , such as the interface contact should not be firm and easy to shake, hot swapping is not supported, abnormal power failure data is easy to lose, there is no three-proof (waterproof, dustproof, shockproof) function, and the normal u...

[0002] Solid State Drives (Solid State Drives) are hard disks made of solid-state electronic memory chip arrays. They are composed of control units and storage units (FLASH chips, DRAM chips). They have fast reading and writing, light weight, and The characteristics of low energy consumption and small size make it popular rapidly. According to relevant statistics, shipments in 2015 increased by 25.8% to 102.78 million pieces. The trend of gradually replacing traditional mechanical hard drives is obvious. However, ordinary solid-state drives have many defects. , such as the interface contact should not be firm and easy to shake, hot swapping is not supported, abnormal power failure data is easy to lose, there is no three-proof (waterproof, dustproof, shockproof) function, and the normal use environment of consumer grade is between 0°C and 70°C, which cannot meet the requirements. Application requirements in military, locomotive, industrial and other fields, and the current interface types of solid-state hard drives adopt SATA interface, SAS interface, MSATA interface, PCI-E interface, NGFF interface, CFast interface and SFF-8639 interface, and these interfaces are drawer type Connection method, the connection strength is small, easy to shake, unable to withstand large mechanical vibration
