Abstract

An integrative fasten clipping mechanism for radiation sheets respectively presets a fasten clipper for radiation sheet materials to close to various corners. A neck bending sheet is flushed by two separated open grooves at the fasten clipper and the level extended sheet of the top end beyond the upper and the lower end edges of radiation sheet materials is bended into two separated ear parts. The neck bending sheet can bend along the internal end to the front surface of the radiation sheet materials and can cause the two side ear parts to be separated clipping arms to be clipped and to clip the neck bending sheet of the front adjacent radiation sheets, thus realizing the firm and reliable fastening and clipping.

Description

Integral buckling and clamping mechanism of radiating fin

Technical field

The relevant a kind of integral buckling and clamping mechanism of radiating fin of the utility model, You Zhike directly molds firm engagement partly easily in fin.

Background technology

With existing heat abstractor is example, its contain usually fin in a row for treat that heat sink reclines and combine, cooperate the auxiliary conduction of active cooling package and heat abstractor, can dispel the heat for various heat-producing devices.Therefore, promptly form necessary large tracts of land heat conduction member by the fin that most fin constituted.

In existing heat abstractor, though the one-body molded heat sink that can be constituted with the high thermal conductivity material is arranged, generally cost is higher.As for the synthetic mechanism of arranging of most groups of fins, then involve and must locate and the winding member in fin use in twos, not only constituent components is uneconomical for it, and follow-up assembling processing also bothers and takes a lot of trouble.Though and existing this type of heat abstractor has to dash between fin in twos and establishes relative sags and crests, for being engaged with each other the location in a row, its combined structure quite built on the sand.

The utility model content

The purpose of this utility model is promptly providing a kind of integral buckling and clamping mechanism of radiating fin, and it can establish snapping portion in the directly pre-subpunch of this fin, makes the structure of the locating engagement between fin moulding easily in twos, and forms solid and reliable clamping connection state.

For reaching above-mentioned purpose, the utility model is preset snapping portion at the lamellar body material of fin respectively near each corner, these snapping portions dash with two open slots that separate and set out the neck bent sheet, with and the top exceed the up and down horizontal-extending sheet of ora terminalis of lamellar body material, set out two ears separately for folding greater than neck bent sheet width; Above-mentioned neck bent sheet can along in it to the greatest extent end make above-mentioned both sides ear become the separately jig arm for the treatment of clamping, down to clamp the neck bent sheet of the adjacent fin in the place ahead towards the front surface bending of lamellar body material.

A kind of integral buckling and clamping mechanism of radiating fin, pre-subpunch sets out snapping portion in each corner of lamellar body material of moulding fin, this snapping portion is by the open slot of each corner upper and lower side near both sides place's punching out preseting length, and the lamellar body material horizontal-extending portion of ora terminalis is up and down slightly stretched out in formation, these extensions can be constituted to the bending of lamellar body material front surface direction treat that snapping partly, at fin in twos and when connecing, i.e. these snapping portions of pressing finish the winding location.

In possible embodiments, the lamellar body material outside above-mentioned two open slots partly all can be bent in advance and establish flanging, is provided as the spacing member.

Embodiment

Novelty of the present utility model and other characteristics will cooperate the following drawings embodiment detailed description preferably.

At first see also Fig. 1, in type fin is improved in the mechanism, establishing upper hem 11,13 and lower hem 12,14 in order to lamellar body material 10 4 corners of making this fin are curved respectively, provides the spacing effect when fin engages in twos.In contiguous other then default respectively two snapping portions 20 of jig arm forward separately of containing of lower hem 11,12,13,14 on these.

The work flow of Fig. 2～above-mentioned snapping of 5 demonstrations portion 20, as shown in Figure 2, though it only shows a corner of lamellar body material 10, same procedure all can be carried out in lamellar body material 10 4 corners.For convenience of description, the ora terminalis up and down of lamellar body material 10 is denoted as 15, and its left and right sides ora terminalis then is denoted as 16.The utility model is at first established two open slots that separate 17,18 dashing near both sides ora terminalis 16 places, to form a class such as T shape sheet vacant state, this T shape sheet is promptly in order to constitute required snapping portion 20, it comprises a neck bent sheet 21, and one is positioned at its top and the outstanding horizontal-extending portion 22 of ora terminalis 15 up and down.Above-mentioned open slot 17,18 extends inward into one section preseting length by ora terminalis 15 up and down, with the preceding folding length of decision snapping portion 20.

Then, can be in regular turn shown in the 3rd, 4 figure, respectively horizontal-extending portion 22 foldings be set out both sides ear 23,24, and dash in neck bent sheet 21 and to establish in order to increase the recessed broken line 25,26 that it is subjected to force intensity and overlap joint usefulness.Its interior 171,181 horizontal levels of holding to the greatest extent along two open slots 17,18 can be bent forward then, become the horizontal-extending portion 22 of higher position shown in Figure 5.Simultaneously, the material piece body part in open slot 17,18 outsides is along holding 171 foldings to be set as the upper hem 13 that spacing is used to the greatest extent in the open slot, and above-mentioned both sides ear 23,24 becomes the separately jig arm shape for the treatment of clamping connection.

According to above-mentioned snapping portion 20 horizontal-extending portion 22 is folded left and right sides ear 23,24, to form two jig arm width greater than its neck bent sheet 21, the lamellar body material 10,100 of fin thereby can and be connected into state shown in Fig. 6～9 in twos.At first and connect the step of two lamellar body materials 10,100, down be clipped in the neck bent sheet of the second lamellar body material 100 for the ear 23,24 that makes the first lamellar body material 10 earlier, then these ear's 23,24 formed jig arm are carried out bending process and become interior turn of bilge 230,240, so that solid and reliable buckling and clamping effect to be provided, so clamping connection can form the fin in a row shown in the 9th figure in regular turn.

Though above illustrated embodiment is converted into lower hem 11,12,13,14 with the lamellar body material in open slot 17 outsides, being provided as in twos, the retaining between fin leans on the spacing member.But it also can be shown in the 10th figure, at the curved distance flanging of setting of the lamellar body material of open slot 18 inboards.That is, directly bend the whole road lower hem 120 that spacing is used at the following ora terminalis of lamellar body material 101.

The utility model since in twos the joint between fin and spacing with member all with single lamellar body The material punch forming, it is except easy making process and need not to use the advantage of extra accessory, in twos Clamping connection structure between fin is also more solid and reliable.
