(1) technical field
The relevant a kind of circuit board assemblies of the utility model relates in particular to a kind of circuit board assemblies that can effectively anti-electromagnetic interference.
(2) background technology
Along with development of computer, the speed of the signal of computer transmission is more and more high, and electric connector can produce galvanomagnetic effect on its motherboard in the high-frequency circuit running, might influence the signal transmission of other electronic building brick on the circuit board.And the operate as normal of other electronic product around the high-frequency electromagnetic effect that is produced in these electric connector transmission can influence, though some electric connector on the circuit board itself is provided with the device of anti-electromagnetic interference, but still have the part electric connector that anti-electromagnetic interference device is not set, still can have described problem.
Therefore, necessary the available circuit board component is improved, to overcome described defective of the prior art.
(3) utility model content
The purpose of this utility model is to provide a kind of circuit board assemblies that can effectively prevent electromagnetic interference.
For achieving the above object, the utility model adopts following technical scheme: a kind of circuit board assemblies comprises circuit board, some electric connectors, loam cake and lower cover.Circuit board comprises the substrate that is provided with some galvanic circles, and described electric connector is assembled on this substrate; Loam cake is assembled on the surface of circuit board, goes up cap surface certainly and projects upwards the resettlement section that is formed with the described electric connector of coating, at the some frame mouths that are provided with the electric connector docking port corresponding align on some and the circuit board on the sidewall of resettlement section; Lower cover is assembled on another surface of circuit board, and the position is corresponding with loam cake, descends cap surface to be recessed to form depressed part downwards certainly.
Compared with prior art, the utility model circuit board assemblies has following beneficial effect: in the upper and lower upper and lower cover structure that is provided with respectively of circuit board, part electric connector on the circuit board can be coated, can effectively prevent the electromagnetic interference when the electronic component signal transmits on the circuit board under the high frequency environment.
For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.
(4) description of drawings
Fig. 1 is the perspective exploded view of the utility model circuit board assemblies.
Fig. 2 is the solid combination schematic diagram of the utility model circuit board assemblies.
(5) embodiment
See also shown in Figure 1ly, the utility model circuit board assemblies 1 comprises circuit board 2, some electric connectors 22,24, loam cake 3 and lower cover 4.
Circuit board 2 comprises that the surface is provided with the rectangular substrate 21 of galvanic circle (not shown), and electric connector 22,24 is assembled on this substrate 21, wherein has the pin (not shown) of part electric connector to penetrate substrate 21 and reach substrate 21 belows.The docking port 221 of some electric connectors 22 is arranged along circuit board one lateral margin.In the present embodiment, electric connector 22 can be digital visual interface (Digital Visual Interface, be called for short DVI) electric connector, compression-type can be wiped storage card (Compact Flash Card, be called for short the CF card) electric connector and serial advanced technology attachment (Serial Advanced Technology Attachment, be called for short S-ATA) electric connector etc., electric connector 24 can be flexible print wiring board (FlexiblePrinted Circuit, be called for short FPC) electric connector, peripheral parts interconnected (Peripheral ComponentInterconnect, being called for short PCI) electric connector and plate be to plate (Board To Board is called for short BTB) electric connector etc.On substrate 21, be formed with some screws 23.
During assembling, loam cake 3 is fastened on the upper surface of the substrate 21 of circuit board 2, the host cavity of its resettlement section 32 coats the some electric connectors on the described substrate 21 22 and accommodates, the described frame mouth 323 of resettlement section 32 aligns with the docking ports of these electric connectors 22 of being accommodated just, and the screw 33 on the loam cake 3 aligns one by one with screw 23 on the substrate 21 at this moment.Lower cover 4 is assembled in substrate 21 lower surfaces and loam cake 3 corresponding positions, and its depressed part 42 is positioned at the pin below of the electric connector 22 that loam cake 3 coated.Can be in advance during lower cover 4 cover in assembling with mylar or other insulating material (not shown) pin with described electric connector 22, perhaps in the depressed part 42 of lower cover 4, establish one deck insulating material (not shown) with the pin that prevents electric connector 22 between short circuit mutually.Screw 33,23 corresponding alignment of the screw 43 on the lower cover 4 and loam cake 3 and substrate 21 lock together loam cake 3, circuit board 2 and lower cover 4 by screw rod 5 then.
The utility model circuit board assemblies 1 coats the electric connector on the circuit board 2 22 by upper and lower cover 3,4, can effectively prevent the electromagnetic interference of circuit board in high-frequency transmission, and do not need respectively each electric connector to be provided with shielding casing respectively, its manufacture craft is convenient and simple.
