Yet, because general plastic casing has the dead angle when plated film, four of the loam cake of mobile computer right angles (inner face) for example, be difficult in film-plating process complete plating conducting film in this zone, therefore, how to make coatings discontinuity zone and circuit board conducting effectively and reach the effect of ground connection, become the important topic on the anti-system of electromagnetic wave.
The utility model content
The utility model purpose promptly provides the conducting structure of anti-preparative layer of a kind of housing electromagnetic wave and circuit board ground connection.
Technological means of the present utility model is: the conducting structure of anti-preparative layer of a kind of housing electromagnetic wave and circuit board ground connection, and in first embodiment, it comprises: a housing is formed with the anti-preparative layer of an electromagnetic wave at this surface of shell, and offers one first perforate; One circuit board is formed with a ground plane at this circuit board surface; One locking conductor, by first perforate of this housing wear by and contact the ground plane of this circuit board.
In second embodiment of utility model, circuit board has a pedestal and offers one second perforate, can be for the locking of locking conductor in second perforate.
In the 3rd embodiment of utility model, second perforate directly is opened in circuit board surface and is a perforation, for the locking conductor directly by first perforate of housing wear by and be locked in second perforate of circuit board.
In the 4th embodiment of utility model, circuit board is equiped with a collar, and has the screw of a predetermined bore, can for the locking conductor by first perforate of housing wear by after be locked in the screw of the collar.
In the 5th embodiment of utility model, can accompany an elastic construction between housing and the circuit board, for example, can be a kind of conductive rubber, can for the locking conductor wear by, make the locking conductor can more firmly be incorporated between housing and the circuit board.
Via the technological means that the utility model adopted, can be incorporated into housing and circuit board via the locking conductor, the electromagnetic wave that can reach housing is prevented the purpose that the ground plane of preparative layer and circuit board electrically conducts.And then make its effect that reaches ground connection, to reach the electromagnetic purpose of control effectively.
