Further improvement of the utility model is, described insulation film is arranged in described back plate main body by adhesive linkage.
Further improvement of the utility model is, described back plate main body and insulation film are provided with hollow-out parts.
Further improvement of the utility model is, described hollow-out parts is arranged at above the components and parts of described pcb board.
Further improvement of the utility model is, described hollow-out parts is respectively arranged at chip near-end filtration module and the top of chip far-end filtration module of described pcb board.
Further improvement of the utility model is, the surface configuration of described back plate main body has insulating barrier.
Further improvement of the utility model is, described back plate main body is linked together by screw and/or snap features with described pcb board.
Further improvement of the utility model is, one end of described back plate main body is provided with bending part.
Further improvement of the utility model is, described back plate main body is respectively connecting to the base plate of described pcb board and video card by bending part.
This utility model also provides for a kind of video card, and described video card includes video card backboard as above.
Compared with prior art, the beneficial effects of the utility model are: be provided with hollow-out parts for the pcb board rear-side height components and parts more than 1mm and pin positions thereof in back plate main body and insulation film, and then avoid these components and parts and pin thereof, on the basis of realizing insulation, the height that can also make back plate main body can accomplish below 2.67mm, meets industry standard, and when multiple video card is applied in combination, do not affect air channel, perfect heat-dissipating；Further; insulation film it is provided with between described back plate main body and pcb board; the surface of described back plate main body is further preferably provided with insulating barrier; and then can dual avoid because the back plate main body brought of manufacturing tolerance and components and parts pins contact on pcb board and the drawback of short circuit, the protection for video card provides one layer of protection more.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings, preferably embodiment of the present utility model is described in further detail.
As it is shown in figure 1, this example provides a kind of video card backboard, including: back plate main body 1 and insulation film 2；Described back plate main body 1 is arranged at the back side of video card 3, and is connected with the pcb board of described video card 3；Described insulation film 2 is arranged between described back plate main body 1 and pcb board.
The pcb board that back plate main body 1 described in this example is video card 3 provides protection, prevents pcb board stress deformation；Described insulation film 2 is arranged in described back plate main body 1 by adhesive linkage, and described adhesive linkage is preferably glue layer, i.e. described in state insulation film 2 be preferably arranged in described back plate main body 1 by modes such as stickups by the adhesive linkage of glue layer or other forms.
As it is shown in figure 1, be provided with hollow-out parts 4 on back plate main body 1 described in this example and insulation film 2, described hollow-out parts 4 is arranged at above the components and parts of described pcb board, and then is easy to the components and parts of pcb board and the design of circuit thereof and layout；Preferably, described hollow-out parts 4 is respectively arranged at chip near-end filtration module and the top of chip far-end filtration module of described pcb board, described chip near-end filtration module and chip far-end filtration module are respectively near-end filtration module and the far-end filtration module of main control chip, so reason of design is, the chip near-end filtration module of described pcb board and chip far-end filtration module would generally use wave filter or electric capacity etc. to filter components and parts, there is certain height, therefore, need chip near-end filtration module and the required above of chip far-end filtration module at described pcb board that hollow-out parts 4 is set.
Described in this example, the surface of back plate main body 1 is preferably provided with insulating barrier.Such as, described back plate main body 1 uses sandblasting anode processing technique so that it is surface possesses insulating barrier, and then avoid making back plate main body 1 and the components and parts pins contact on pcb board because of manufacturing tolerance, it is to avoid video card is short-circuit and affects using effect.
Described in this example, back plate main body 1 is linked together by screw and/or snap features with described pcb board.
As shown in Figure 1; described in this example, one end of back plate main body 1 is provided with bending part 5; described back plate main body 1 is respectively connecting to described pcb board and the base plate of video card 3 by bending part 5; so arrange; the bending part 5 that is forced through enabling to pcb board is transferred on the base plate of video card 3; reduce the stress of described pcb board, protect described pcb board further.
This example also provides for a kind of video card 3, and described video card 3 includes video card backboard as above.
In traditional design, pcb board back side components and parts and the pin of described video card 3 are more, also ratio comparatively dense, and the void region design difficulty of back plate main body 1 is relatively big, the more weakened also causing back plate main body 1 in void region, it is impossible to play the effect supporting pcb board.This example is by arranging insulating barrier on the surface of back plate main body 1, or, the methods such as insulation film 2 are set between pcb board and back plate main body 1, reduce the risk of pcb board short circuit, reduce the design difficulty of the hollow-out parts 4 to back plate main body 1, simultaneously, additionally it is possible to reduce the height of video card backboard 1, the requirement to manufacturing tolerance is reduced.
This example is provided with hollow-out parts 4 for the pcb board rear-side height components and parts more than 1mm and pin positions thereof in back plate main body 1 and insulation film 2, and then avoid these components and parts and pin thereof, on the basis of realizing insulation, the height that can also make back plate main body 1 can accomplish below 2.67mm, meet industry standard, and multiple video card 3 is when being applied in combination, do not affect air channel, perfect heat-dissipating；Further; insulation film 2 it is provided with between described back plate main body 1 and pcb board; the surface of described back plate main body 1 can also be preferably provided with insulating barrier; and then can dual avoid because the back plate main body 1 brought of manufacturing tolerance and components and parts pins contact on pcb board and the drawback of short circuit, the protection for video card 3 provides one layer of protection more.
The detailed description of the invention of the above is better embodiment of the present utility model; not limit with this and of the present utility model be embodied as scope; scope of the present utility model includes being not limited to this detailed description of the invention, and the equivalence change that all shapes according to this utility model, structure are made is all in protection domain of the present utility model.
