Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
Embodiment: refer to shown in Fig. 1 ~ 4, for the preferred embodiment of the dielectric base structure of radiator fan of the present invention, only these embodiments are intended for purposes of discussion, are not limited by this structure in patent application.Described insulating base A includes:
One metal seat board 10, it has multiple air-permeating hole 11 and is positioned at a median plate portion 12 of described air-permeating hole 11 zone line, and described median plate portion 12 is provided with inlay card joint portion 20；
One plastic support 30, have a binding end 31 and and protrude out end 32, described binding end 31 combine be fixed on the inlay card joint portion 20 set by described median plate portion 12, described in protrude out end 32 effect as it is shown on figure 3, axle center 06, stator coil 07 and circuit board 08 group for blast fan 05 set and are used.
Wherein, as shown in Figure 3,4, the binding end 31 of this plastic support 30 also can be formed with an expanding section 33 and relative definition forms a shoulder 34, therefore supporting role can be formed by breasting bottom the described shoulder 34 circuit board 08 for blast fan 05, and make circuit board 08 spacing spaced apart with metal seat board 10；Also, the big I of external diameter of described expanding section 33 be Fig. 3, the state shown in 4, the median plate portion 12 with metal seat board 10 that also can be set as is equal to the embodiment of area.
Wherein, the inlay card joint portion 20 in described median plate portion 12 can be multiple to stretch, towards plastic support 30 binding end 31 direction, the dog sheet 21 set and constitute, as for the combination of plastic support 30 binding end 31 with described dog sheet 21, mould can be used to make plastic support 30 integrally extrude Overmolded with described dog sheet 21；Also, described dog sheet 21 stretch set form can the most inclined angle state；Or dog sheet 21B as shown in Figure 5, it is one vertically to tortuous angle state.
