In some embodiments, the material of insulation cover body is PS or PC.Its beneficial effect is: the insulation cover body of PS or PC material has good stability and sanction property.
In some embodiments, the thickness of insulation cover body is 0.3 ~ 1.6 millimeter.Its beneficial effect is: can reach good support strength while the insulating cover weight of this thickness alleviates, and also has simultaneously and saves material, cost-saving beneficial effect.
In some embodiments, metal conducting layer comprises the first metal layer, the second metal level and the 3rd metal level, the first metal layer is nickel dam, second metal level is layers of copper, 3rd metal level is silver layer or 18K layer gold, metal level is overlying on the external side of insulating cover, and the second metal level is overlying on the first metal layer, and the 3rd metal level is overlying on the second metal level.Its beneficial effect is: the metal conducting layer of three-decker has good spreadability, such as, desultory situation may be there is when being covered with separately one deck nickel dam, now cover the continuity that the second metal level and layers of copper just can increase metal conducting layer thereon, in order to have better conductive effect, can also be covered with 18k layer gold or silver layer in layers of copper, the product obtained can shield electromagnetism effectively.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of the radome of the utility model one execution mode;
The structural representation of the mould that Fig. 2 matches for radome shown in Fig. 1;
Fig. 3 is the structural representation after the mould matched moulds in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, the utility model provides a kind of radome, and comprise insulation cover body 1 and be arranged on the metal conducting layer 2 on outside insulation cover body 1, the thickness of metal conducting layer 2 is 0.001 ~ 0.003 millimeter.The material of its insulation cover body 1 is PS or PC.The thickness of insulation cover body 1 is 0.3 ~ 1.6 millimeter.Metal conducting layer 2 comprises the first metal layer 201, second metal level 202 and the 3rd metal level 203, the first metal layer 201 is nickel dam, second metal level 202 is layers of copper, 3rd metal level 203 is silver layer or 18K layer gold, the first metal layer 201 is overlying on outside insulation cover body 1, second metal level 202 is overlying on the first metal layer 201, and the 3rd metal level 203 is overlying on the second metal level 202.Its beneficial effect is: the metal conducting layer 2 of three-decker has good spreadability and adhesiveness, such as, desultory situation may be there is during nickel dam coating, now be covered with the continuity that the second metal level 202 i.e. layers of copper just can increase metal conducting layer 2 thereon, in order to have better conductive effect, can also be covered with 18k layer gold or silver layer in layers of copper, the product obtained can shield electromagnetism effectively.
With reference to Fig. 2 and Fig. 3, the mode of vacuum suction moulding can be adopted to prepare the insulation cover body 1 of radome.Specific as follows: to prepare the mould for the preparation of insulation cover body 1, the male model 4 that this mould comprises a master mold 3 and matches with this master mold 3, master mold 3 is provided with die cavity 302, two through holes 301 are provided with below die cavity 302, for being connected with vacuum absorption device (not shown), male model 4 is provided with the protuberance 401 matched with this die cavity 302.Insulating sheet material 5 i.e. PS plate or PC plate are close to and are placed on master mold 3 and heat, heating-up temperature is 60 ~ 130 degree, 10 ~ 15 seconds are incubated after making PS plate or PC plate become soft state, then two through holes 301 below master mold 3 die cavity 302 are vacuumized, the PS plate of soft state or PC plate are close in the profile in die cavity 302 along with the agency part of pull of vacuum, the size of pull of vacuum can be 0.8 ~ 1.5 MPa, the time vacuumized can be 1 ~ 3 second, subsequently male model 4 and the master mold 3 being equipped with PS plate or PC plate are carried out matched moulds and adopt water-cooling pattern to carry out cooling and shaping, as shown in Figure 3.After mold cools down, again male model 4 and master mold 3 are carried out die sinking, take out the first product of shaping insulation cover body 1, then carry out trimming finishing to it and obtain the cover body 1 that insulate, the thickness of insulation cover body 1 is 0.3 ~ 1.6 millimeter.
