Description
Technical field
The utility model relates to a kind of Vehicular charger, especially a kind of Vehicular charger EMC component individual screen structure.
Background technique
The filter circuit of motor is common following two mounting means: one is be directly installed on motherboard；It is main in this way
The electromagnetic interference generated on machine plate can go here and there to filter circuit front end (close to AC input), reduce the filtering of filter circuit
Effect；Another kind is to increase shielding case in the external of filter circuit；Although this measure can reduce electromagnetic radiation pair on motherboard
The interference of filter circuit, but since space limits, often shielding case is closer from filter coil, can generate coupling, still
It can cause the crosstalk between front stage filter network, ideal filter action, i.e., the EMC filtering unit of traditional charger is not achieved
Shield shell is that the copper sheet being fixed on PCB plate is constituted, and shield effectiveness is poor, and since the pcb board is set to radiation aluminium
In shell, assembling production is complicated, is not easy to assemble.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of Vehicular charger to solve the shortcoming in background technique
EMC component individual screen structure.
In order to achieve the above objectives, the utility model adopts the following technical solution: a kind of Vehicular charger EMC component independently shields
Shield structure, including die casting aluminum hull set PCB filtering unit, die casting aluminum hull side peripheral hardware charger connector, charging in die casting aluminum hull
Machine connector and PCB filtering unit are electrically connected, and shielding isolation cabin, the shielding isolation cabin and die casting aluminium are equipped in die casting aluminum hull
Shell is connected as one.
A kind of optimization for the utility model, shielding isolation cabin are to be isolated by the first input isolation cavity plate, the second input
Cavity plate and die casting aluminum hull inner wall enclose the metallic shield storehouse of composition.
A kind of optimization for the utility model offers installing port on die casting aluminum hull, and charger connector passes through installation
Mouth is electrically connected with PCB filtering unit.
A kind of optimization for the utility model is covered with aluminium lid, the first input separate cavities above die casting aluminum hull
Several screw holes are offered respectively on plate, the second input isolation cavity plate and die casting aluminum hull, and connecting by several screws with screw hole makes
Aluminium lid fixation is covered on die casting aluminum hull.
The utility model compared with the background art, have it is structurally reasonable, make it is convenient for production；It is set in the application die casting aluminum hull
There is shielding isolation shell, and the shielding isolation cabin is metal screen case, the radiation of generation can be absorbed by metal screen case, from
And prevent interference internal circuit and peripheral electrical equipment；Shielding isolation cabin is to be isolated by the first input isolation cavity plate, the second input
Cavity plate and die casting aluminum hull enclose the metallic shield storehouse of composition, and the shielding isolation cabin and die casting aluminum hull are the one knot of direct pouring
Structure, thus convenient for production, low manufacture cost；Aluminium lid is set on die casting aluminum hull by several screws and screw hole connection cover, thus logical
Multiple screw multipoint earthings are crossed, low cost and effective EMC shield effectiveness is realized, is easily assembled, be suitble to produce in enormous quantities.
