Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
See also Fig. 1, the heat abstractor 100 of one embodiment of the invention comprises a substrate 10 and is located at a fastening structure 20 on this substrate 10.This fastening structure 20 is used for this heat abstractor 100 is fixed on a circuit board with electronic component, and this substrate 10 is contacted with electronic component heat conduction on the circuit board.
Please consult simultaneously Fig. 2, offer a semicircle shape otch 14 on this substrate 10.These substrate 10 bottoms are to forming a tabular support portion 12 in otch 14 places, and the part of this support portion 12 extends beyond this substrate 10.These support portion 12 central authorities offer a substantially oblong-shaped perforation 13.The inner surface of this perforation 13 comprises two relative arc surfaces 132 and the plane 134 parallel with being arranged between two arc surfaces 132 two.Be appreciated that ground, the inner surface of this perforation 13 also can be two cambered surfaces that curvature is different of docking, or the combination of a plane and a cambered surface.
This fastening structure 20 comprises a fastener 21 and is nested with a flexible member 23 on this fastener 21.Be a spring in these flexible member 23 present embodiments, certainly can also be other elastomers such as shell fragment.Described fastener 21 comprises the operating portion 211 of a fixed part 210, a circle and a connecting portion 212 between this fixed part 210 and this operating portion 211.
Please be simultaneously with reference to Fig. 3, this fixed part 210 is column, and its outer surface is offered screw thread, is used for this heat abstractor 100 is fixed to circuit board.This connecting portion 212 is a cylindric stock.This connecting portion 212 outwards is convexly equipped with the fastening part 213 of a lengthwise near the periphery level at these fixed part 210 places.The side of this fastening part 213 comprises two relative arc surfaces 214 and is arranged on two parallel planes 215 between two arc surfaces 214.Intersect the plane at each 215 place, plane and the side of this connecting portion 212.This fastening part 213 is coupled with the structure of the perforation 13 of this substrate 10, that is to say, shape and the in the same size of the perforation 13 of the shape of this fastening part 213 and size and this substrate 10, when this fastening part 213 pierces into the perforation 13 of this substrate 10, two arc surfaces 214 of this fastening part 213 fit with two arc surfaces 132 of this perforation 13, and two planes 215 of this fastening part 213 fit with two planes 134 of this perforation 13.The sectional area of this fastening part 213 is greater than the sectional area of this connecting portion 212.This operating portion 211 extends upward formation from the other end of this connecting portion 212, and these operating portion 211 central authorities offer a cross groove 216, for cooperating with instrument this heat abstractor 100 is fixed to circuit board.This flexible member 23 is between the operating portion 211 of this fastener 21 and fastening part 213 and be sheathed on this connecting portion 212.The diameter of this operating portion 211 is greater than the internal diameter of this flexible member 23.The diameter of the diameter of this connecting portion 212 and this fastening part 213 so that this fastening part 213 passes this flexible member 23, is set on this connecting portion 212 this flexible member 23 all less than the internal diameter of flexible member 23.
