At present, the electromagnetic environment of industry spot is more abominable, if power line is not processed, will cause to the device of cabinet inside very large interference.
The utility model content
The purpose of this utility model is to provide a kind of screen protective device of enclosure power line, in order to suppress electromagnetic interference to the impact of power line EMC performance.
For achieving the above object, the utility model provides a kind of screen protective device of enclosure power line, comprising: connect some power lines of mainboard and power interface, also comprise:
Some magnet rings, it is nested on power line;
Copper foil layer, it covers power line and magnet ring, and with described power line and magnet ring and casing phase fixing;
Press strip, it is arranged on the end, two ends of described copper foil layer, in order to clamping the end, two ends of copper foil layer and power line, and by some bolts and casing phase fixing.
As further improvement of the utility model, described magnet ring is nested in the centre position of power line.
As further improvement of the utility model, described copper foil layer is the viscosity copper foil tape.
As further improvement of the utility model, the thickness of described copper foil layer is 0.1mm.
As further improvement of the utility model, the thickness of described press strip is 0.5mm.
As further improvement of the utility model, described press strip is copper.
Compared with prior art, the beneficial effects of the utility model are: in the present invention, and nested magnet ring on the power line of casing, and by covering, copper foil layer and press strip are set on power line and magnet ring.By this structure, realized the shielding processing to power line, effectively suppressed the impact of electromagnetic interference on the EMC performance of power line.
Description of drawings
Fig. 1 is the structural representation in screen protective device one embodiment of a kind of enclosure power line of the utility model.
