Technical Field
The utility model discloses an anti radiation interference's motor shell of adjusting luminance relates to anti radiation interference technical field.
Background
In the prior art, no good method for reducing radiation interference exists in the electromagnetic compatibility test of the vehicle headlamp direct current motor dimmer, and an additional radiation-proof part needs to be added between a plastic shell and an internal electronic element in the prior art, so that the effect of metal shielding is achieved, the occupied space is large, the weight is large, and the light dimmer is easy to fall off after a long time.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the defect among the above-mentioned background art, provide an anti radiation interference's motor shell of adjusting luminance, it is little to have occupation space, light in weight, advantage with low costs.
In order to achieve the above object, the utility model adopts the following technical scheme: a dimming motor housing resistant to radiation interference, comprising: diapire and lateral wall, form an open-ended cavity between lateral wall and the diapire and be used for placing electronic component, set up metallic shield on one of them lateral wall and the diapire, metallic shield surface cover stainless steel layer, the diapire sets up vertically and horizontally staggered's strengthening rib, the strengthening rib separates into a plurality of regions with the diapire, and metallic shield position does not receive product self structural constraint, can set up metallic shield according to the region according to actual need, and is complete and have the selectivity, and the strengthening rib can also play the reinforcing action to shell intensity except can dividing the coating region, lateral wall edge set up the screw hole for with to the locking piece assembly.
Furthermore, the metal shielding layer material is copper coating or aluminum coating, and the material has the environmental protection, and is pollution-free, harmless, high heat conduction and electricity conduction, corrosion resistance, oxidation resistance, suitable intensity and easy machine-shaping.
Furthermore, the thickness of the metal shielding layer is 10-15 μm, and a layer of metal film is attached to the surface of the plastic material by utilizing the electrolytic action, so that the metal shielding layer is formed, the thickness of the coating film is uniform and is easy to control, and the position and the area of the coating film can be accurate.
Further, the stainless steel layer is made of 1Cr18Ni 9.
Further, the thickness of the stainless steel layer is 0.1-0.5 μm.
Further, the bottom wall and the side wall are made of one or more materials selected from PC, ABS, PS, PP and PBT.
Has the advantages that: 1. the utility model discloses need not increase extra radiation protection part between plastic casing and inside electronic component to reach the effect that has metal shielding, can effectual reinforcing anti-radiation interference ability, and product low in manufacturing cost.
2. The metal shielding layer of the utility model is very thin and is between 10 and 15 mu m, thereby achieving the characteristics of small occupied space and light weight.
3. The utility model discloses at first structural stability is high, does not drop easily like additionally increasing the part, and metallic shield layer stable in structure, and metallic shield layer surface covering stainless steel layer prevents that the metallic shield layer from by the oxidation, and the anti-interference time of preventing protecting against radiation is lasting, and the reliability is high.
