Description

Fastener of heat sink

[technical field]

The utility model is about a kind of fastener of heat sink, is meant especially that a kind of button is held conveniently, smooth operation and labour-saving fastener of heat sink.

[background technology]

Flourish along with electronic industry, the large scale integrated circuit technology is constantly progressive, the release of high-frequency high-speed processor is accelerated day by day, yet, the high-frequency high-speed operation will make the caloric value of electronic building brick increase, distribute if heat is untimely, will cause the electronic building brick internal temperature to raise, have a strong impact on the stability of electronic building brick operation.

Single now dependence electronic building brick self dispels the heat and can not satisfy practical application request fully, and industry installs a radiator additional on the electronic building brick surface and comes auxiliary heat dissipation.For radiator is firmly closely contacted with the heating electronic building brick, then adopt a fastener that radiator is pressed on heating electronic building brick surface.

In the prior art, fastener has a central pressure section usually and by these central authorities pressure section two ends upwardly extending two elastic portion that tilts respectively, each elastic portion free end bending downwards is extended with buckling parts, and the buckling parts end is provided with button hole.Be pressed on the radiator by central pressure section, button hole is fastened on the respective bump of connector, and radiator is fixed on heating electronic building brick surface.Be not difficult to find out that this fastener needs bigger button hold power owing to self rigidity when button is held, even need be by extra instrument, therefore, regular meeting is because undue force injures electronic building brick.

Therefore patent announcement No. 474425 disclosed fastener of heat sink in Taiwan just arranged.Its improvement to aforementioned fastener of heat sink is: the both side edges of central pressure section bends two tabs vertically downward, is used for articulating an operating body, and this operating body comprises an one handle and a cam-like pressure section.Rotary handle, this cam-like pressure section can push against or leave heat sink.This fastener no doubt has suitable improvement to aforementioned fastener of heat sink, but, this fastener is to rotate in by handle drive cam-like pressure section to realize buckle on the heat sink, need overcome certain frictional force, and occur the stuck phenomenon that can't rotate of operating body easily.

[summary of the invention]

The purpose of this utility model is to provide a kind of button to hold convenience, smooth operation and labour-saving fastener of heat sink.

The purpose of this utility model realizes by following technical proposal:

The utility model fastener of heat sink comprises a fastener main body, a lever and a slide bar.This lever comprises pulls arm, perk arm and fulcrum.Fulcrum place tool one roller can roll on slide bar.Perk arm end is rotatably connected on the fastener main body.Pull the arm of pulling of lever, make perk arm jack-up fastener main body, thereby fastener main body two ends are buckled on the stuck-module.

The utility model fastener of heat sink adopts lever construction to make fastener carry out buckle, adopts roller to roll on slide bar at the fulcrum place of lever simultaneously, makes the buckle of fastener laborsaving, steadily and convenient.

Fig. 2 is the stereogram of the fastening radiator of the utility model fastener of heat sink on the CPU stuck-module.

Fig. 3 is the three-dimensional view of the utility model fastener of heat sink.

Fig. 4 is another three-dimensional view of the utility model fastener of heat sink.

[embodiment]

See also Fig. 1 and Fig. 2, the utility model fastener of heat sink 70 is used for radiator 20 is fixed in central processing unit (CPU) stuck-module 10.

CPU stuck-module 10 comprises a square framework and extends four fixed legs 12 that form for four jiaos vertically upward by framework that each fixed leg 12 is provided with a fixing hole 14.

Radiator 20 is contained in the square framework interior (being the CPU top) of CPU stuck-module 10, and its four jiaos is four fixed legs 12.Radiator 20 comprises a pedestal and some radiating fins that extends on this pedestal.The two ends of this radiator 20 are two boss 22, and the height of boss 22 is lower than the height of radiating fin, in order to support fastener 70.

See also Fig. 3 and Fig. 4, fastener 70 comprises a main body 60, a lever 50 and a slide bar 30.Main body 60 comprises horizontal part 61, is formed centrally a slotted hole 64 in the horizontal part 61, and the both sides of slotted hole 64 form vertically downward on two parallel flanging 62, two flangings 62 and relatively respectively form a pivoting hole, in order to connect lever 50.The perk obliquely of the two ends of horizontal part 61 forms both wings 63.Both wings 63 further extend to form two fastener arms 65 downward vertically.Position, fastener arm 65 lower middle forms a containing hole 68, in order to hold slide bar 30.Two fastener sheets 69 are inwardly vertically turned up in the terminal both sides of fastener arm 65, on the fixed leg 12 that is buckled in CPU stuck-module 10.Wherein on the fastener arm 65, above containing hole 68, also form an elongated hole 67, can allow lever 50 pass therethrough.For strengthening the rigidity of fastener main body 60, can form flange in the both sides at positions such as horizontal part 61, both wings 63, fastener arm 65.

Lever 50 is L-shaped, comprises pulling an arm 55 and a perk arm 56 the perk arm 56 terminal pivoting holes that form.When perk arm 56 ends stretch in the slotted hole 64 of fastener main body 60 horizontal parts 61 from the below, the pivoting hole of perk arm 56 is corresponding just with the pivoting hole on two flangings 62 of horizontal part 61 belows, can utilize a pivotal axis 54 to pass these pivoting holes, lever 50 and fastener main body 60 are rotatably connected.The fulcrum of lever 50 (being lever 50 " L " shape bending part) comprises a rotating shaft 53 and sheathed plastic roller 40 on it.Rotating shaft 53 is vertically outwards formed by plane, lever 50 place.This roller 40 can roll on slide bar 30.The arm 55 of pulling of lever 50 passes from the elongated hole 67 of fastener main body 60, and its terminal bending also flattens and forms one handle 52.

Slide bar 30 is an elongated body of rod, as the roller track of lever 50 rollers 40.A projection 31 is protruded at slide bar 30 middle parts.Slide bar 30 is near two ends places, and level inwardly forms one " S " bending 32, so that the two ends of slide bar 30 can be inserted in the containing hole 68 on 60 liang of fastener arms 65 of fastener main body.Slide bar 30 two ends are driven plain, and in embedding containing hole 68, thereby guarantee that slide bar 30 is positioned between the two fastener arms 65 of fastener main body 60.

As shown in Figure 1, during fixed heat sink 20, the slide bar 30 of fastener 70 is placed on the boss 22 of radiator 20 and (also can place on other plane of radiator, but need to provide the activity space of fastener 70), the fastener sheet 69 of 70 liang of fastener arms 65 of fastener snaps in the fixing hole 14 of CPU stuck-module 10 fixed legs 12, at this moment, fastener sheet 69 is loosening buckle with the buckle of fixing hole 14.

Then, pull the handle 52 of lever 50 downwards, roller 40 is rolled on slide bar 30,, stop to pull lever 50 until its projection 31 of crossing slide bar 30.At this moment, because the horizontal part 61 of fastener 70 is by the perk arm 56 of lever 50 jack-up upwards, promptly whole fastener 70 is by jack-up upwards, the fastener sheet 69 of fastener arm 65 have upwards motion trend and with fixing hole 14 chuckings of fixed leg 12.And the barrier effect of slide bar 30 projectioies 31 can not rolled back roller 40 backward, thereby guarantees that fastener 70 firmly holds radiator 20.
