Technical field
The utility model relates to the communications field, in particular to a kind of screening arrangement.
Background technology
Along with the development of large scale integrated circuit be extensive use of, EMI has become the problem that can't neglect.As electromagnetic anti-intrusion device spare, the use of radome is also more and more general.Radome be with shield with component, circuit, sub-assembly, the interference source of cable or whole system is surrounded, and prevents that interfere with electromagnetic field is to outdiffusion; With receiving circuit, equipment or system are surrounded with shield, prevent that they are subjected to the influence of external electromagnetic field.
It is material that the material of radome adopts thick stainless steel of 0.2mm and foreign copper-nickel alloy usually, the mode that generally adopts shielded rack and shield combination to use.Doing has so not only increased the area that takies but also increased the thickness that takies.
The utility model content
Increase the defective of area occupied and thickness for overcoming the radome shielded rack that exists in the existing radome scheme, the utility model provides a kind of screening arrangement, reduces radome shielded rack area occupied and thickness simultaneously.
To achieve these goals, according to an aspect of the present utility model, provide a kind of screening arrangement.
Comprise according to screening arrangement of the present utility model: first pcb board; Second pcb board, and parallel placement relative with first pcb board; First shielded rack and secondary shielding frame are connected with second pcb board with first pcb board, form airtight cavity; And connector, between first pcb board and second pcb board, be connected with second pcb board with first pcb board.
Further, connector is positioned within the airtight cavity.
Further, connector is positioned at outside the airtight cavity.
Further, screening arrangement also comprises: the 3rd shielded rack and the 4th shielded rack, be connected with second pcb board with first pcb board, and form the second airtight cavity; Connector is positioned within the second airtight cavity.
Further, first shielded rack, secondary shielding frame, first pcb board and second pcb board are by being welded to connect.
Further, the 3rd shielded rack, the 4th shielded rack, first pcb board and second pcb board are by being welded to connect.
Adopt screening arrangement of the present utility model, reduce radome shielded rack area occupied and thickness, reduced printed circuit board (PCB) (Printed Circuit Board abbreviates PCB as) slab integral thickness, save the area of pcb board integral body, reduced the use cost of individually shielded cover.
