Embodiment
Refer to 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, for this heat abstractor 100 is fixed on the circuit board that has electronic component, makes this substrate 10 and the electronic component thermal conductive contact on circuit board.
Please refer to Fig. 2, this substrate 10 is offered a semicircle shape otch 14.To forming the support portion 12 of a tabular in otch 14 place bottom this substrate 10, a part for 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 two that are arranged between two arc surfaces 132.Understandably, the inner surface of this perforation 13 also can be the cambered surface that two curvature of docking is different, 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.Being a spring in this flexible member 23 the present embodiment, can also be other elastomers such as shell fragment certainly.Described fastener 21 comprises a fixed part 210, circular operating portion 211 and a connecting portion 212 between this fixed part 210 and this operating portion 211.
Referring to Fig. 3, this fixed part 210 is in column, and its outer surface offers screw thread, for this heat abstractor 100 is fixed to circuit board.This connecting portion 212 is a cylindric stock.The fastening part 213 of the periphery of this connecting portion 212 near this fixed part 210 place horizontally outward projection lengthwise.The side of this fastening part 213 comprises two relative arc surfaces 214 and is arranged on the parallel plane 215 of between two arc surfaces 214 two.The plane at each plane 215 place is crossing with 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, the shape of the perforation 13 of the shape of this fastening part 213 and size and this substrate 10 and in the same size, 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 upwards extends to form from the other end of this connecting portion 212, and these operating portion 211 central authorities offer a cross groove 216, for coordinating with instrument, this heat abstractor 100 is fixed to circuit board.This flexible member 23 is between the operating portion 211 and fastening part 213 of this fastener 21 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 this connecting portion 212 and the diameter of this fastening part 213 are all less than the internal diameter of flexible member 23, so that this fastening part 213 is through this flexible member 23, this flexible member 23 are set on this connecting portion 212.
Referring to Fig. 4, during installation, this flexible member 23 is set on the connecting portion 212 of this fastener 21, the fastening part 213 of this fastener 21 aims at the perforation 13 of this substrate 10, the fastening part 213 of this fastener 21, through the perforation 13 on this substrate 10, makes described fastening part 213 and flexible member 23 be placed in the both sides, support portion 12 of substrate 10 respectively.Then this fastening part 213 is horizontally rotated certain angle, such as 90 degree, make this fastening part 213 be stuck in the bottom surface of the support portion 12 of this substrate 10.Now flexible member 23 is compressed between the operating portion 211 of this fastener 21 and the support portion 12 of this substrate 10, flexible member 23 applies strong a, elastic force upwards to this operating portion 211, limit fastener 21 to move relative to perforation 13, thus this fastening structure 20 is arranged on this substrate 10 securely.
During dismounting, this fastener 21 rotates to an angle relative to the perforation 13 of this substrate 10, make this fastening part 213 aim at the perforation 13 of this substrate 10, this flexible member 23 recovers deformation makes this fastener 21 depart from this substrate 10, completes and is dismantled from this substrate 10 by this fastening structure 20.Understandably, the angle that this fastener 21 rotates relative to this substrate 10 is not limited to 90 degree, also can be other angles.
Compared with prior art, fastening structure 20 compact conformation of heat abstractor 100 of the present invention is firm, is convenient to installing/dismounting, and there is not the risk come off from heat abstractor 100 in the processes such as transport.In addition, the fastener 21 of this fastening structure 20 is formed with fastening part 213 to replace the circular gasket of prior art, decreases the quantity of the part of fastening structure 20, in the process of production, reduce the human cost of assembling circular gasket.
Be understandable that, for the person of ordinary skill of the art, other various corresponding change and distortion can be made by technical conceive according to the present invention, and all these change the protection range that all should belong to the claims in the present invention with distortion.
