Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to an IC fin mounting mechanism which can be easily mounted and removed.

[0002]

2. Description of the Related Art In order to cool an IC that generates a large amount of heat, a fin having a large surface area is attached to the IC. Since the IC may be removed due to a failure or the like, a structure that can remove the IC with the fin is required.

Next, a conventional fin mounting mechanism will be described with reference to FIG. In FIG. 4, 10 is an IC, 11 is a block, 12 is a fin, and 13 is a male screw. Block 11
Has a plurality of female threads 11A, and the fin 12 has a hole 1
A plurality of 2A are opened.

In FIG. 4, a block 11 is adhered to an IC 10 with an adhesive having good heat conductivity, and a fin 12 is attached to the block 11.
And fix it with the male screw 13. To remove the IC 10, the male screw 13 is removed, the fin 12 is taken, a soldering iron is applied to the lead of the IC 10, and the IC 10 is removed.

[0005]

FIG. 4 shows the fins 12 to be solved.
Is fixed with a plurality of male screws 13, and it takes time to attach and remove the fins. An object of the present invention is to provide an attachment mechanism that allows a fin to be attached to and detached from an IC with a single male screw.

[0006]

In order to achieve this object, according to the present invention, a plate-like stopper 1 attached to an IC 10 and a cylindrical projection 2 formed with a female screw 2A and attached to the stopper 1 are provided. And a fin 3 having a hole 3A into which the projection 2 enters, and a presser 4 formed in an L-shape and having a hole 4A into which the male screw 5 enters.

[0007]

Next, an IC fin mounting mechanism according to the present invention will be described with reference to FIG. 1 is a stopper, 2 is a protrusion,
3 is a fin, 4 is a presser, and 5 is a male screw.

The plate-shaped stopper 1 is attached to the IC 10. As a method of attaching the stopper 1 to the IC 10, for example, the stopper 1 is bonded with a heat conductive adhesive to reduce contact thermal resistance. The cylindrical projection 2 is attached to the stopper 1. A female screw 2 </ b> A is formed on the projection 2. The stopper 1 and the projection 2 can be integrally formed. The presser 4 is formed in an L-shape, and has a hole 4A into which the male screw 5 is inserted.

Next, the relationship between the projections 2 and the fins 3 in FIG. 1 will be described with reference to FIG. 3A is a hole. The fin 3 is provided with a hole 3A into which the projection 2 enters.

The projection 2 is inserted into the hole 3A of the fin 3, and the fin 3 is placed on the stopper 1. At this time, the holding tool 3 is
Then, the fin 3 is placed so as to hit the side surface of the screw, the male screw 5 and the female screw 2A are screwed together, and the fin 3 and the presser 4 are fixed. When the presser 4 contacts the side surface of the stopper 1, the stopper 1 serves to stop the rotation of the presser 4.

To remove the IC 10, the male screw 5 is removed, the retainer 4 and the fin 3 are removed, and the IC 10 is removed by applying a soldering iron to the lead of the IC 10.

Next, the assembly drawing of FIG. 1 will be described with reference to FIG. 3A is a plan view, FIG. 3A is a sectional view taken along line AA of FIG. 3A,
FIG. 3C is a sectional view taken along line BB of FIG. 3A.

[0013]

According to the present invention, the fin can be assembled and removed with one male screw. In addition, since the presser contacts the side surface of the stopper, the stopper stops rotation of the presser.
