Description

Heat abstractor

The utility model is a kind of heat abstractor, refers in particular to a kind of heat abstractor that is used to distribute the heat that central processing unit produces.

The prior art relevant with this case sees also United States Patent (USP) the 6th, 031, and No. 725 and 4,674, No. 811.See also shown in Figure 1, the electric connector 12 that is used to carry central processing unit 11 is positioned at circuit board 14 by the holding unit 13 of insulation, wherein group is provided with metal earthing device 15 on the holding unit 13, the radiator 16 that is used for and is installed on the central processing unit 11 electrically connects, thereby the electric charge on the radiator 16 is connected to circuit board 14.But existing earthing device 15 is unlike materials with holding unit 13 owing to them, so fit together after must making separately.So, not only be unfavorable for making and the reduction of assembly cost, make that also the whole constituent components number of this electric connector is more.In addition, the integrated designing requirement single component of electronic product has multiple function, and no matter holding unit 13 still is the function that earthing device 15 all can not provide fixing and ground connection simultaneously.

The purpose of this utility model is to provide the less and fixing effect of a kind of whole constituent components heat abstractor preferably.

The purpose of this utility model is to realize by following technical scheme: heat abstractor comprises radiator and holding body, and wherein radiator has base portion and is located at several cooling fins on the base portion.Holding body is one-body molded by metal, has diapire, by a pair of the first side wall and one second sidewall that the diapire one is extended, and this diapire, the first side wall and second sidewall surround the receiving space that is used for accommodating a radiator part jointly.The first side wall upper end forms outward-dipping guiding face, and the guiding face bottom is provided with the snapping hole.The clamping part that is used for the clamping the first side wall is extended in the second sidewall both sides.Second sidewall is provided with several louvres that is used to improve heat-sinking capability side by side.Diapire is provided with coupling hole and ground strip, and this coupling hole can pass and diapire is fixed on the circuit board for an affixed body, and ground strip contacts with radiator to discharge the electric charge on it.This heat abstractor also includes shell fragment, and its middle part forms pressure section, and the two ends of this pressure section are provided with the snapping portion of bending, and each snapping portion is provided with the snapping sheet that can be interlockingly connected with the snapping hole of holding body diapire, is used for strengthening the locating effect of heat abstractor.

Compared with prior art, advantage of the present utility model is: the whole constituent components of heat abstractor less and its have better positioning effect.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the partial exploded view of existing heat abstractor and central processing unit, electric connector and circuit board.

Fig. 2 is the partial exploded view of the utility model and central processing unit, electric connector and circuit board.

Fig. 3 is the unit assembly drawing of Fig. 2, and wherein the shell fragment of heat abstractor is still unassembled.

Fig. 4 is the three-dimensional combination figure of Fig. 2.

See also Fig. 2 and shown in Figure 3, the heat that the central processing unit 3 that the utility model is used for being fixed in the socket connector 2 is produced distributes, and wherein socket connector 2 is fixed on the circuit board 7.This heat abstractor comprises the radiator 4 that is arranged on the central processing unit 3, be used for socket connector 2 is fixed to holding body 5 and shell fragment 6 on the circuit board 7.Radiator 4 comprises the base portion 41 of level and several cooling fins 42 disposed thereon.

Holding body 5 is by the one-body molded manufacturing of metal material, have diapire 50, a pair of the first side wall 51 and one second sidewall 52, this the first side wall 51 and second sidewall 52 all extend upward and surround a receiving space 53 perpendicular to bottom surface 50, are used for accommodating the part of radiator 4.Diapire 50 punching out go out to be connected to two depression 50a of circuit board 7 one sides.Each depression 50a has coupling hole 50b, and fastener 54 can pass the through hole (not shown) on this coupling hole 50b and the circuit board 7 and holding body 5 is fixed on the circuit board 7.Further punching out goes out relative a pair of ground strip 50c on the diapire 50.The first side wall 51 upper ends have outward-dipping guiding face 51a, are used for guiding radiator 4 and shell fragment 6 insertions.The below that the first side wall 51 is positioned at guiding face 51a is provided with snapping hole 51b.Second sidewall, 52 both sides laterally extend clamping part 52a near the first side wall 51 places, and this clamping part 52a is one by the barb-like structure clamping the first side wall 51 of its end and make first,

second sidewall

51,52 fixings.Second sidewall 52 is provided with several louvre 52b that is used to increase radiating effect.

Shell fragment 6 comprises tabular pressure section 61 and extends the snapping portion 62 that the back forms bending obliquely by pressure section 61 relative both side edges that each snapping portion 62 upper punch is made snapping sheet 62a.The lateral border of pressure section 61 is provided with the extension 63 on the lateral surface that abuts in holding body 5 second sidewalls 52.

It is extremely shown in Figure 4 please to consult Fig. 2 simultaneously, during assembling, at first socket connector 2 and holding body 5 is placed on the circuit board 7, and central processing unit 3 is inserted socket connectors 2, radiator 4 is organized by the guiding of guiding face 51a to be located on the central processing unit 3 simultaneously.Because the ground strip 50c position of diapire 50 is higher, so radiator 4 contacts and do not contact with the upper surface of fastener 54 with this ground strip 50c.The pressure section 61 of shell fragment 6 is abutted against the base portion 41 of radiator 4, make snapping portion 62 abut against the outside of holding body 5 second sidewalls 52.Then push snapping portion 62 downwards it is moved along guiding face 51a, the snapping sheet 62a of snapping portion 62 is buckled in the snapping hole 51b of the first side wall 51.Rely on above-mentioned architectural feature, can guarantee closely to contact between radiator 4 and the holding body 5, so that the two mutual heat conduction and electrical conductivity.
