Abstract
A kind of antidetonation solid state hard disc mounting structure, includes daughter board PCB and motherboard PCB9, it is characterised in that：There are daughter board pad and motherboard pad respectively on daughter board PCB and motherboard PCB, the daughter board pad and motherboard pad add hemispherical to agree with (toothed edge of interlaced adaptation) structure using stamp hole, there is thermally conductive insulating layer between daughter board PCB and motherboard PCB, daughter board pad and motherboard pad solder are fixed, and are also fixed on daughter board PCB and motherboard PCB with fixing bolt.Its advantage is to realize accurate docking, the contact area of increase joint face, reduction impedance and signal attenuation, while substantially overcomes the big signal attenuation of contact point impedance, oxide etch, vibration that the original electric board golden finger way of contact easily occurs and loosen, dock the problem of inaccurate.Electric board and computer card are combined into a rigid body, have stronger shock resistance.
Description
Technical field
It the utility model is related to for record or reproducing apparatus and the device about equipment collaboration operation, be related to for depositing
Record structure member, parts or the annex of carrier, espespecially a kind of antidetonation solid state hard disc mounting structure.
Background technology
The SSD memory of prior art such as MSATA, 2.5 inches of SATA/SAS, M.2, U.2, PCI-E etc. do not consider to tackle
The adverse circumstances such as high temperature, low temperature, high-intensity magnetic field, strong static discharge, moisture, mould, salt fog, shock and vibration.In some extreme environments
Application in reliability cannot ensure, some of reinforcement measure can only be relied on to be made up the day after tomorrow, often produced little effect.
Industrial electronics manufacturer generally carries out the Design of Reinforcement of storage system by the following method both at home and abroad at present：Design
Based on the single product (or even onboard SSD chips on function mainboard) such as XMC, VPX, PMC, advantage is the congenital reinforcing in part
Layout board fixture has certain protection to impact shock for wide temperature, by three proofings coat measure possess certain salt spray resistance,
Damp and hot, mould characteristic, the disadvantage is that, volume is bigger, space-consuming is more, or even take independent groove position, high-low temperature resistant degree scope
Limited, vibration and shock resistant characteristic dependent on structural member, connector and particular design PCB costs it is higher, three proofings measure with
The effect of time gradually reduces barrier propterty decline, effectively protects the life-span to be usually no more than 10 years.Partly domestic outer portion manufacturer
Consider reinforcement measure using direct onboard SSD method is just synchronous when board designs, consolidation effect is preferable, but there is also account for
With pcb board space, increase board cost, the problem of maintenance difficulty is increased, storage medium can not during especially for secrecy-involved apparatus
Dismounting often adds maintenance difficulty.Directly onboard SSD media also constrain following upgrade expanding of storage product in addition, especially
It is the fields such as track traffic, radar communication, navigation, unmanned plane, intelligence analysis.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of antidetonation solid state hard disc mounting structure.
Technical scheme is used by the utility model solves its technical problem：A kind of antidetonation solid state hard disc installation knot is provided
Structure, include daughter board PCB and motherboard PCB, it is characterised in that：There are daughter board pad and motherboard weldering on daughter board PCB and motherboard PCB respectively
Disk, the daughter board pad and motherboard pad add hemispherical to agree with (toothed edge of interlaced adaptation) structure using stamp hole, son
There is thermally conductive insulating layer between plate PCB and motherboard PCB, daughter board pad and motherboard pad solder are fixed, and are gone back on daughter board PCB and motherboard PCB
Fixed with fixing bolt.
Further：SATA or SAS signals, power-supply wiring to PCB edge are passed through zigzag half by electric board daughter board PCB
Eyelet welding disk is drawn.Facilitate edge to weld, enhancing welding contact area and reliability, in addition this mounting means also allow for design and
Radome is installed, good electromagnetic shielding is provided when electric board signal is upgraded to 12G by current 6G.Entirety possesses good
Detachability, it is easy to upgrading.
The beneficial effects of the utility model are：Electric board daughter board PCB and computer card motherboard PCB9 are agreed with, and are used
Stamp hole adds hemispherical to agree with (toothed edge of interlaced adaptation) structure, realizes accurate docking, the contact of increase joint face
Area, impedance and signal attenuation are reduced, while substantially overcome the contact that the original electric board golden finger way of contact easily occurs
The big signal attenuation of point impedance, oxide etch, vibration loosen, dock the problem of inaccurate.Electric board and computer card are combined into
One rigid body, there is stronger shock resistance.

Embodiment
Referring to accompanying drawing, a kind of antidetonation solid state hard disc mounting structure of the utility model, include daughter board PCB 3 and motherboard PCB
9, it is characterised in that：There are daughter board pad 5 and motherboard pad 7, the He of daughter board pad 5 on daughter board PCB 3 and motherboard PCB 9 respectively
Motherboard pad 7 adds hemispherical to agree with (toothed edge of interlaced adaptation) structure, daughter board PCB 3 and motherboard PCB using stamp hole
There is thermally conductive insulating layer 2 between 9, daughter board pad 5 and motherboard pad 7 are welded and fixed, and fixation is also used on daughter board PCB 3 and motherboard PCB 9
Bolt 1 is fixed.
Electric board daughter board PCB 3 and computer card motherboard PCB 9 are agreed with, and are employed stamp hole and are added hemispherical to agree with
(toothed edge of interlaced adaptation) structure, realize that accurate docking, the contact area of increase joint face, reduction impedance and signal decline
Subtract, while substantially overcome the big signal attenuation of contact point impedance, oxidation that the original electric board golden finger way of contact easily occurs
Burn into vibration loosens, docks the problem of inaccurate.Electric board and computer card are combined into a rigid body, have stronger resist
Vibration performance.
In embodiment of the present utility model, electric board daughter board PCB 3 is by SATA or SAS signals, power-supply wiring to PCB sides
Edge, by half bore pad, by using zigzag half bore pad structure, edge is facilitated to weld, enhancing welds contact area and can
