Detailed Description

The present application is described in further detail below with reference to the attached drawings.

The application discloses a heat sink integrated configuration.

Example 1:

a heat sink combination structure, refer to FIG. 2, comprises an upper cover 100 and a lower cover 200, wherein the upper cover 100 and the lower cover 200 are both rectangular, a female buckle plate 110 is arranged on a long edge of each side of the upper cover 100, and a male buckle plate 210 is arranged on a long edge of each side of the lower cover 200. The female buckle plate 110 and the male buckle plate 210 are perpendicular to the upper cover 100 and the lower cover 200, respectively. When the upper cover 100 and the lower cover 200 are fastened, the inner wall of the female fastening plate 110 is abutted against the outer wall of the male fastening plate 210, that is, the female fastening plate 110 is sleeved on the male fastening plate 210.

Referring to fig. 2 and 3, the female buckle plate 110 has a female buckle point 120 for being embedded into the male buckle plate 210, the male buckle plate 210 has a male buckle point 220 for being embedded into the motherboard, and both the female buckle point 120 and the male buckle point 220 have a buckle surface 300 for matching. The female fastening point 120 and the male fastening point 220 are spaced apart along the horizontal direction to form at least two sets, in this embodiment, three sets are provided, the fastening surface 300 of the middle set is vertically disposed, that is, perpendicular to the lower cover 200, and the fastening surfaces 300 of the two sets on both sides are both horizontally disposed. And the three groups are located at the same height.

Referring to fig. 4, 5 and 6, in order to achieve the locking effect, the female locking plate 110 has a circular female locking hole 123, and the male locking plate 210 has a male locking hole 223 aligned with the female locking hole 123 and also has a circular shape. In this embodiment, the female snap point 120 includes a semicircular inner concave portion 121 disposed at the edge of the snap hole, and the male snap point 220 includes a semicircular outer convex portion 221 disposed at the edge of the snap hole. The edge of the female snap-in hole 123 has a first connecting ring portion 122, the cross section of the first connecting ring portion 122 is a quarter circle, and the length of the first connecting ring portion 122 is a half arc, and is matched with the inner concave portion 121. One straight edge of the first connecting ring portion 122 is connected to the edge of the male snap hole 223, and the other straight edge is connected to the side of the female portion 121. Similarly, the edge of the male snap hole 223 has a second connecting ring portion 222, the cross section of the second connecting ring portion 222 is a quarter circle, one straight edge of the second connecting ring portion 222 is connected to the edge of the male snap hole 223, and the other straight edge is connected to the side surface of the external protrusion 221.

The straight edges of the inner concave part 121 and the outer convex part 221 are fastening surfaces 300, after the male buckle plate 210 is fastened with the female buckle plate 110, the inner concave part 121 is embedded into the male fastening hole 223, the outer convex part 221 is embedded into the female fastening hole 123, the inner concave part 121 and the outer convex part 221 form a locking round block 400, when the outer convex part 221 is embedded into the female fastening hole 123, the outer side of the female buckle plate 110 is higher than the top of the outer convex part 221, so that the outer side surface is flat, and no convex part exists. In order to facilitate the fastening and reduce the requirement of processing precision, a gap is formed between the two fastening surfaces 300. The fastening surface 300 can define the male fastening plate 210 and the female fastening plate 110 in a direction perpendicular thereto.

When the lock, will make interior recess 121 contradict on public buckle 210, and outer convex part 221 will contradict on female buckle 110, when the lock joint, will imbed to the lock joint that corresponds downthehole, in order to reduce the motion resistance of public knot point 220 and female knot point 120, the fillet face 310 of interior recess 121 for being used for with the conflict in female knot hole 123 border, the fillet face 310 of the fillet of outer convex part 221 for being used for with the conflict in public knot hole 223 border, can play the effect of direction when moving through fillet face 310.

Referring to fig. 7, in the actual installation process, the upper cover 100 may be installed reversely when being fastened, so in this embodiment, the female fastening points 120 on both sides of the upper cover 100 are symmetrically disposed, and the male fastening points 220 on both sides of the lower cover 200 are symmetrically disposed. If the installation is reversed, the box point 120 and the pin point 220 of the middle group are located in the same semicircle and cannot form a complete locking round block 400, so that the fool-proof effect is achieved. In normal fastening, the male portion 221 and the female portion 121 are located on two sides, respectively, to form a complete locking round piece 400.

The thickness of female buckle plate 110, the thickness of male buckle plate 210, the diameter of the cross section of first connecting ring portion 122, the diameter of the cross section of second connecting ring portion 222, the thickness of concave portion 121 and the thickness of convex portion 221 are the same in this embodiment, so that the whole body can be processed and finished through stamping at the moment, and the structure is simple and reliable.

In other embodiments, the male fastening hole 223 and the female fastening hole 123 can also be rectangular, and the inner concave portion 121 and the outer convex portion 221 can be two rectangular sheets corresponding to the fastening holes, and only in this embodiment, the semicircular shape is provided, and the circular arc edge can facilitate smooth fastening.

The implementation principle of the embodiment 1 of the application is as follows: when the lock joint, can be through preventing slow-witted setting, correct to upper cover 100 and lower cover 200, make female buckle 110 and male buckle 210 peg graft each other this moment, outer convex part 221 will deform with interior concave part 121, when female lock joint hole 123 and male lock joint hole 223 are right-hand member, outer convex part 221 will be embedded into female buckle 110 in, and interior concave part 121 will be embedded into in the male buckle 210. The two sets of fastening surfaces 300 are horizontally arranged to achieve upper and lower limit, and the fastening surfaces 300 are vertically arranged to achieve left and right limit.

Example 2:

the difference from embodiment 1 is that, referring to fig. 8, the distance of the middle group of box points 120 and pin points 220 from the lower cover 200 is smaller than that of the remaining two groups. At this moment, when the lock, the lock joint surface 300 is a vertically arranged group, and can be locked in advance, whether the lock joint surface is mistakenly installed or not can be judged during contact, when the error is found, the lock joint surface can be directly disassembled, and the lock joint surfaces 300 horizontally arranged on the two sides are not locked, so that the adjustment is convenient.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
