Screen layer will be added on parallel conductor layout upper and lower surface, on the line by parallel conductor layout the top line and bottom line
Attribute is changed to GND, and parallel conductor layout will not increase the hardness of product inside a shield；Bending place increases on the line
GND, so not increasing the width of parallel conductor layout, in space than narrow place, being not in that cable is more difficult passes through
Situation.Material original is saved, and realizes the purpose shielded to parallel conductor layout.
The beneficial effects of the present invention are preposition cabinet is carried out conductive spraying and will by technical scheme
The place that VGA connector and USB connector contact with preposition cabinet carries out conductive spraying, machine is formed one completely
Shield.Mounting hole carries out conductive spraying, avoids the interference of common-mode signal.
By the first contact pin pin and last contact pin pin and master of VGA connector and USB connector during motherboard design
The ground of plate（GND）Connection；Screen layer will be added on parallel conductor layout upper and lower surface, on the line by parallel conductor layout the top line and most
The attribute of lower end line is changed to GND, and parallel conductor layout will not increase the hardness of product inside a shield；Bending place is in circuit
Upper increase GND, be not in that cable is more difficult in space than narrow place so not increasing the width of parallel conductor layout
Situation about passing through.Material original is saved, and realizes the purpose shielded to parallel conductor layout.
In addition, design principle of the present invention is reliable, and it is simple in construction, there is very extensive application prospect.
As can be seen here, the present invention compared with prior art, has prominent substantive distinguishing features and significantly improved, it is implemented
Beneficial effect be also obvious.
