Abstract

The utility model relates to a heating radiator fastening device used for fastening a heat radiator onto the surface of an electronic assembly, which comprises a fastening tool and two fixed pins, wherein the fastening tool comprises a connecting body and an operating body pivotally jointed to the connecting body. The connecting body comprises a body and arm parts extending downwards from both ends of the body. Each arm part is hollow, and a horizontal direction slide slot is formed at the bottom; an inlet communicated with the slide slot is formed on the side wall. When assembled, the two fixed pins passes through a back board, a circuit board and a heat radiator in sequence. The fastening tool is positioned in a groove of the heat radiator, and the fastening is horizontally moved, which makes the fixed pins stuck in the two slide slots of the fastening tool; the operating rod is wrenched, which causes a pressing part to be contacted with the surface of the heat radiator, thereby, the heat radiator is tightly pressed onto the surface of the electronic assembly.

Description

Buckling device of radiator

[technical field]

The utility model is about a kind of buckling device of radiator, refer to especially a kind of have cam gear and assemble convenient, fasten firm buckling device of radiator.

[background technology]

Along with the fast lifting of electronic building brick operating frequency, the heat that it produced is also increasing.For in time discharging the heat that electronic building brick produced, guarantee its normal operation, the volume and weight of the radiator that is adopted also increases thereupon.Thereby, cooperate high-strength spring by screw usually or by a high-intensity elastic fastener with the reliable electronic building brick heating surface that is fixed in of radiator, as United States Patent (USP) 6,373, No. 704 and 6,343, No. 015.But this class fixture needs by screwdriver or other special fixture auxiliary operation in disassembly process, causes production efficiency decline, production cost to improve, and very easily damage printed circuit board (PCB) or peripheral precision components etc. because of careless manipulation.Therefore, how to provide a kind of assemble convenient, to fasten firm buckling device of radiator be problem to be solved in the utility model.

[summary of the invention]

The purpose of this utility model is to provide a kind of buckling device of radiator convenient, that fastening is firm of assembling.

The purpose of this utility model is achieved through the following technical solutions: the utility model buckling device of radiator, be used to fasten radiator in the electronic building brick surface, and comprise a fastener and two steady pins.This fastener comprises that a connector and is articulated in the operating body on the connector, the arm that this connector has a body and extends downwards from the body two ends.Each arm all is a hollow, and the chute of a horizontal direction is formed on the bottom, and sidewall forms an inlet that is connected with chute.During combination, two steady pins pass backboard, circuit board and radiator in order, and this fastener is placed in the radiator groove, move horizontally this fastener, and steady pin is snapped in two chutes of fastener; Pull action bars, make the press section be resisted against spreader surface, thereby compress radiator in the electronic building brick surface.

Owing to adopted technique scheme, the utility model buckling device of radiator to have the advantage that assembling is convenient, fastening is firm.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 2 is the three-dimensional exploded view of the fastener of the utility model buckling device of radiator.

[embodiment]

See also Fig. 1, the utility model buckling device of radiator is to be used for a radiator 30 is fitted tightly on an electronic building brick 20 surfaces, comprises a fastener 60 and two steady pins 50.

This electronic building brick 20 is placed on the circuit board 10, and this circuit board 10 forms one second through hole 12 respectively in the both sides of this electronic building brick 20.One backboard 40 is attached at the lower surface of circuit board 10, and forms two first through holes 42 corresponding to second through hole 12 of circuit board 10.

This radiator 30 comprises a horizontal base 32 and some fins 34 of arranging from the parallel interval that horizontal base 32 extends vertically upward.Form the groove 36 of a vertical fin bearing of trend in the middle of this radiator 30, and correspond respectively to two third through-holes 38 of second through hole, 12 places formation of circuit board 10 in groove 36 bottoms.

One end of each steady pin 50 forms the bigger head of a diameter 52, and the other end forms a buckle end 56, forms an annular slot 54 near buckle end place.Steady pin 50 just can pass through first through hole 42, second through hole 12 and third through-hole 38; The diameter of the head 52 of steady pin 50 is greater than the diameter of first through hole 42.

Please consult Fig. 2 together, this fastener 60 comprises an integrally formed connector 62 and an operating body 90 that is articulated on this connector 62.This connector 62 comprises a body 64 and the linking arm 68 that extends vertically downward from the body two ends.This body forms a storage tank 70 that connects from top to bottom in about middle part, and forms the coaxial connecting hole 72 that a level connects respectively in the corresponding storage tank of dual-side 70 middle parts.This linking arm 68 is a hollow, and its horizontal bottom is a cramp 69, and this cramp forms a chute 74.Wherein the chute 74 of a linking arm 68 continues to extend a bit of distance on these linking arm 68 1 inner vertical walls, communicates with a bigger inlet 76 on this inner vertical walls.The chute 74 of another linking arm 68 continues to extend a bit of distance on these linking arm 68 1 perpendicular outer wall, communicate with a bigger inlet 76 on this perpendicular outer wall.The height of the annular slot 54 of steady pin 60 is slightly larger than chute 74 height in vertical direction.

Operating body 90 comprises a cam-like press section 94 and a self-pressing portion 94 outward extending action bars 92, near press section 94 and action bars 92 junctions one pivoted hole 96 is arranged.

During assembling fastener 60, the storage tank 70 of connector 62 is put in the press section 94 of operating body 90, make the pivoted hole 96 of operating body 90 corresponding with the connecting hole 72 of connector 62.One drive-connecting shaft 98 inserts connecting hole 72 and pivoted hole 96 successively, thereby operating body 90 pivots are connected on the connector 62.

During use, earlier radiator 30 is placed on the upper surface of electronic building brick 20, backboard 40 is placed on the lower surface of circuit board 10, and makes first through hole 42 of backboard 40, second through hole 12 of circuit board 10 and the third through-hole 38 difference correspondences of radiator 30.Two steady pins 50 pass first through hole 42, second through hole 12 and third through-hole 38 respectively in order, cross third through-hole 38 up to the annular slot 54 of steady pin 50, are arranged in the groove 36 of radiator 30.Fastener 60 is positioned in the groove 36 of radiator 30, two linking arms 68 of fastener 60 lay respectively at the same side of two steady pins 50 again, make the inlet 76 of steady pin 50 facing to immediate linking arm 68.Then, promote two linking arms 68, annular slot 54 slips of two steady pins 50 are snapped in the chute 74 of two cramps 69.At this moment, pull the action bars 92 of operating body 90 downwards, drive press section 94 and rotate, make the base 32 that compresses radiator 30 on the press section 94 from pivoted hole 96 salient point farthest downwards, thereby promote connector 62, radiator 30 closely is fastened on electronic building brick 20 surfaces.This action bars 92 can continue to pull an angle downwards, makes the salient point of press section 94 cross an angle a little, thereby prevents action bars 92 resiliences.Because connector 62 upwards promotes, and makes the buckle end 56 of steady pin 50 be close to the cramp 69 of linking arm 68 and the vertical component of linking arm 68, thereby prevents that steady pin 50 breaks away from away from the inlet of linking arm 68.

During dismounting, upwards pull action bars 92, make the fastening power absent-mindedness between linking arm 68 and the steady pin 50, mobile again connector 62 makes steady pin 50 break away from chute 74, takes off fastener 60 and steady pin 50, thereby easily radiator 30 is disassembled.
