Specific implementation mode
The utility model is described in detail with reference to specific embodiment.Following embodiment will be helpful to this field
Technical staff further understand the utility model.It should be noted that for those skilled in the art, do not taking off
Under the premise of conceiving from utility model, various modifications and improvements can be made, these belong to the protection model of the utility model
It encloses.
Fig. 1 is the structural schematic diagram of the utility model cabinet untethered scheme in succession, including back panel assemblies 1, air plug board group
Part 2, back card/back board 3, fixing device 4, air plug 5, fixed block 6, handle 8 and fixing screws etc..Traditional cabinet is by later
Air plug 5 is fixed on board group part 1 to be connected on bottom plate 10 by cable again, the utility model in order to realize cabinet untethered design (i.e. wirelessly
Prick design), devise the intermediate bridge that air plug board group part 2 arrives bottom plate 10 as connection back panel assemblies 1.Referring to Fig. 3, Fig. 4, originally
The specific implementation process of New Scheme is：First air plug board group part 2 is fixed in back panel assemblies 1, and tight by fixing screws 7
Gu；Each back card/back board 3 is inserted by the female of connector A in the connector A male connectors in air plug printed board 9 again；Finally by
Each back card/back board 3 is inserted into chassis component 13 and forms whole cabinet untethered design scheme by guide rail 12.This scenario-frame is simple,
The cumbersome link such as wiring is avoided, saves the time of cabinet assembly, while cabinet is up and down without cable blocks heat dissipation hole 11,
Convection current is unobstructed between heat emission hole 11 above and below cabinet, substantially increases the heat-sinking capability of cabinet, enhances the security performance of equipment.
In the implementation process for carrying out cabinet untethered connection scheme, there are several technical difficulties.
First, referring to Fig. 2, each air plug 5 is welded in air plug printed board 9 in order to realize, traditional mode is will to navigate
It inserts 5 and first passes through fixing screws 7 and be fixed in air plug printed board 9 and carry out unified welding, after being again assembled to air plug 5 after the completion of welding
On panel assembly 1.But since the thickness of 5 air plug flange (see Fig. 5) of the air plug of different model is generally inconsistent, in panel backward
Each air plug 5 is caused not to be mounted on the same horizontal plane correctly when being installed on component 1；Or even if installation is complete reluctantly,
Also air plug printed board 9 can be caused to deform, make the solder joint of air plug 5 there are stress, cause the security performance of air plug 5 drastically under
Drop.Devise fixed block 6 thus, air plug 5 is first installed on fixed block 6 by when welding, is then refilled and is fitted on air plug printed board 9
On, and fastened by fixing screws 7.The air plug 5 of different air plug flange thicknesses can make to own by adjusting the thickness of fixed block 6
The welding of air plug 5 after the completion of in the same level, so that installation is smoothed out, eliminate the stress of solder joint, improve and set
Standby safety；And fixed block 6 must make of metal material, ensure that the Electro Magnetic Compatibility of cabinet.
Furthermore referring to Fig. 4, back card/back board 3 is connect by connector B females with the male connector of connector B on bottom plate 10 in cabinet.
If the quantity of back card/back board 3 is more, during each back card/back board 3 is inserted into chassis component 13 simultaneously, due between each back card/back board 3
There are larger site errors, it cannot be guaranteed that every piece of back card/back board 3 can be accurately inserted into guide rail 12, it may appear that back card/back board 3 is not
The phenomenon being easily inserted into guide rail 12；In addition, when progress cabinet is safeguarded, 2 component of air plug plate or back card/back board 3 are often extracted into dimension
Repair detection.Since the both ends of back card/back board 3 are to insert in air plug printed board 9 respectively by the female of connector A and the female of connector B
Connector A male connectors and bottom plate 10 connector B male connectors in, when can not ensure to extract back panel assemblies 1 by handle 8, after
Plate 3 is in connector A or the disconnection at connector B, it is easy to the phenomenon for causing plug chaotic.In order to solve above-mentioned two side
Face problem devises fixing device 4, by fixing device 4 in scheme implementation process, while being fixed on air plug printed board 9 with after
On plate 3, and fastened by fixing screws 14.4 one side of fixing device reduces the mistake of the position between each back card/back board 3
Difference makes back card/back board 3 smoothly be inserted into guide rail 12, to realize the smooth assembly of cabinet；On the other hand, it ensure that board group below
When extracted, each back card/back board disconnects part 1 at connector B, avoids the phenomenon of plug confusion.And if it is intended to back card/back board 3
It is disconnected at connector A, if fixing device 4 is installed on bottom plate 10 and back card/back board 3 simultaneously, but need to be in back card/back board 3
Connector A females end installs drawing-aid device additional, is convenient for the plug and repair of back card/back board 3.It is further to note that connector A, B
Male connector and female end can be flexibly set as needed in the both ends of back card/back board 3, and such design is all common in this field
's.
The utility model solves many deficiencies of the cable connection type of equipment cabinets in railway signal industry well,
Bring following technique effect：
One, by the way that air plug board group part 2 to be fixed in back panel assemblies 1, then it is connected with bottom plate 10 by back card/back board 3, it is real
The untethered design for having showed cabinet entirety, improves reliability, the maintainability of equipment, improves the heat-sinking capability of cabinet, improve
The overall performance of equipment.
Two, fixed block 6 is devised, orientation problem when air plug board group part 2 is installed with rear panel 10 is solved, can be compatible with
The connector of different size different models is installed simultaneously, realizes the scheme compatibility of untethered design.
Three, fixing device 4 is devised, solves the orientation problem when plug simultaneously of polylith back card/back board 3, while avoiding and setting
It is standby the phenomenon of back card/back board plug confusion occur when safeguarding.
Four, more traditional cabinet cable connection type, increases air plug printed board 9 and back card/back board 3, on the one hand can will set
The standby partial function to be realized, is transferred on back card/back board 3, for example, can be put into signal acquisition circuit increases device signal
Amount of acquisition channels；On the other hand, traditional 5 port-guard function of air plug is connected on bottom plate 10 by cable by air plug 5, this
Port-guard function can be put on back card/back board 3 by place, keep protection circuit closer from 5 port of air plug, increase equipment in complicated electricity
Anti-interference under magnetic environment；And increase the autgmentability of cabinet function, it is especially limited, to be realized in Cabinet Size
When function is again more, this cabinet untethered connection scheme has more far-reaching inspiration meaning.
The foregoing is merely the preferred embodiments of technical solutions of the utility model, are not intended to limit the utility model
Protection domain.Any modification, equivalent substitution, improvement and etc. made within the spirit and principle of the present invention, should all
It is included within the scope of protection of this utility model.
