Screen line through wires hole interference fit on described rubber bush and matrix; And by magnet ring pressing plate, rubber bush is pressed in substrate.
The size in hole deducts the algebraic difference of the size gained of the axle matched, and is interference when this difference is for bearing.Interference fit: be exactly the cooperation with interference (comprising minimum interference to equal zero).
During use, rubber bush top is inserted the screen line through wires hole of body, then the metal platen end of magnet ring pressing plate is aimed at the bottom of rubber bush, compress, then with the screw fixed orifice of screw by metal platen, be fixed on substrate.
Ferrite wave-absorbing material particle is evenly distributed with in described rubber bush, realize the function of conducting continuity and conversion electromagnetic energy, ferrite wave-absorbing material inhales ripple filled media efficiently, can sorption enhanced electromagnetic wave energy effectively, can ensure again the conducting continuity of junction.
Implant closed flexible metal coil around the barrel of described rubber bush, in order to weaken electromagnetic-wave leakage, flexible metal coil can ensure that rubber has enough deformation, offsets the electromagnetic wave leaked according to electromagnetic induction principle simultaneously.
Described screen line and rubber bush interference closely cooperate.
Described screen line adopts double layer screen technology; each root core outer wrapping insulation course, screen layer and protective seam; the whole same wrap insulate layer of wire harness, screen layer and protective seam, wherein insulation course is high-and low-temperature resistance electrically insulating silicone rubber, and screen layer is 360 ° of flexible metal silk screens.
Beneficial effect of the present invention is:
Through wires hole of the present invention innovatively adopts dismountable encapsulating method, can realize the maintenanceability energy that rainproof function can take into account again computing machine, also facilitates production and processing to assemble simultaneously; Adopt ferrite wave-absorbing material particle, screen line employing double layer screen technology and two magnet ring filtering technique in rubber, effectively raise capability of electromagnetic shielding.
