Fan frame electrical connection structure

A fan frame electrical connection structure comprising:

• a frame body having a wind incoming side and a wind outgoing side respectively disposed on two sides of the frame body, a bearing cup seat being disposed at a center of the wind outgoing side of the frame body, a static blade assembly being integrally formed between an outer circumference of the bearing cup seat and an inner circumference of the frame body, the static blade assembly including multiple static blades and an enclosure static blade, a lead pin set being integrally enclosed in the enclosure static blade, the enclosure static blade having an inner end connected with the outer circumference of the bearing cup seat and an outer end connected with the inner circumference of the frame body, the lead pin set including multiple first plug ends and multiple second plug ends, the first plug ends extending from the inner end of the enclosure static blade to a bottom side of the bearing cup seat to electrically connect with a circuit board, the second plug ends extending from the outer end of the enclosure static blade to a wall section of the frame body to electrically connect with an external lead set, the enclosure static blade having a static blade front edge and a static blade rear edge, the static blade front edge being directed to the wind incoming side and having a front edge arc, the static blade rear edge being directed to the wind outgoing side and having a rear edge arc,
• wherein a static blade upper surface and a static blade lower surface are connected between the static blade front edge and the static blade rear edge, the static blade upper surface being composed of an arcuate face and a straight face, the static blade lower surface being composed of a continuous arcuate curved face and an inclined face, the continuous arcuate curved face having a concave section and a convex section, the concave section extending from the static blade front edge, the convex section extending from the concave section to connect with the inclined face.
