[Technical field to which the invention belongs]

 The present invention relates to a fastener for attaching a heat sink to a kind of CPU, and more particularly to a fastener for attaching a heat sink to a Celeron class CPU of Intel.

[0002]

[Prior art]

 With the rapid advancement and growth of the electronics and telecommunications industries, high computational performance has been required for most of the CPUs used, and the operating temperature has risen significantly due to the improvement in computational efficiency. At present, such a CPU with high computation efficiency is widely used in various electronic equipment, and for example, such a CPU is provided in an interface card of a computer. Although the computer case was provided with a heat radiating fan, the heat radiating of the CPU could not be performed effectively, that is, it did not meet the heat radiating demand of the CPU. When the CPU continued to work in an environment where the working temperature was too high, the overheating affected the computing function and efficiency, and even stopped the computer. For this reason, the heat radiating means to be attached to such a CPU with high operation efficiency has a design which is often seen at present.

At present, such a CPU mounting method is roughly divided into two types. One is the traditional method of directly soldering the CPU body to the computer motherboard. The other is an insertion method in a cassette type CPU. Among them, when getting off, the CPU body is soldered to one connection printed circuit board, the contacts are concentratedly arranged at the bottom end by the circuit of this connection printed circuit board (commonly called gold finger), and the outer layer is cassette. The cassette type CPU is formed by coating. When inserting the cassette type CPU, the connecting printed circuit board is inserted into a connector provided on the motherboard of the computer.

[0004] The cassette type CPU described above has been researched and developed by Intel Corporation, and is currently being actively adopted by computer manufacturers. Intel offers celeron-class CPUs for different classes of use groups, especially in the same plug-in configuration. This is a form in which the cassette case of the external packaging of the above-mentioned cassette type CPU is removed, and the CPU main body is simply soldered to the printed circuit board for connection.

[Problems to be solved by the invention]

 It is an object of the present invention to provide a kind of fastener for attaching a heat sink to a Celeron class CPU.

[0006]

[Means for Solving the Problems]

 The invention according to claim 1 is based on a rectangular main body, and has a front end and a rear end on both sides of the main body. The locking foot is curved and arcuate, and the end of the locking foot is extended downward to form a hook end for locking inward, and the two locking feet on the same side are formed. A fastener for attaching a heat sink to the CPU, characterized in that the upper ends are connected by a single interlocking plate. The invention according to claim 2 is characterized in that the surface of the interlocking plate is curved and formed in an arc shape to enhance the structural strength, and as a fastener for attaching a heat sink to a CPU according to claim 1, I have.

[0007]

[Embodiment of the invention]

 The fastener of the present invention is based on a rectangular main body, and outwardly inclined locking feet extend at both front and rear ends on both sides of the main body, and the locking feet are curved and arcuate. A hook end is provided to extend downward and lock inward, and the upper ends of two locking feet on the same side are connected by one interlocking plate.

[0008]

【Example】

 The fastener 1 of the present invention is based on a rectangular main body 11 and provided with outwardly and upwardly extending locking feet 12 at front and rear ends on both sides of the main body 11, respectively. The hook end 13 is formed in an arc shape and its end is extended downward to lock inward, and one interlocking plate 14 is connected between upper ends of two locking feet 14 on the same side. ing.

FIG. 2 is an exploded view of the combination relationship of the present invention. As shown, the fastener 1 of the present invention is used to combine a heat sink 2 with the aforementioned Intel Celeron level CPU 3. The surface of the CPU 3 is provided with one perforation 32 in a square near the outer periphery of the CPU main body 31, and the perforation 21 corresponding to the perforation 32 is also provided on the bottom surface of the heat sink 2 combined therewith. The main body of the fastener 1 is provided slightly smaller than the CPU main body 31, and enters the corresponding perforation 32 provided in the CPU 3 when the locking foot 12 is opened slightly outward.

As shown in FIGS. 3, 4 and 5, three use states of the present invention are shown. As shown in the figure, the heat sink 2 is placed on the front surface of the CPU 3 to which the CPU body 31 of the CPU 3 has been soldered in advance, and the fastener 1 is placed on the back surface of the CPU 3. At the time of fastening, first, the locking foot 12 on the same side of the fastener 1 is first passed through the corresponding hole 32 on the same side of the CPU 3, and the other locking foot 12 is further opened slightly outward. It is inserted into the perforation 32 of the corresponding CPU 3. After each locking foot 13 is passed through the perforation 32 of the CPU 3, its hook end 13 is located in a perforation 21 provided at a corresponding position on the bottom surface of the heat sink 2. Since each locking foot 12 is curved and formed in an arc shape, when the interlocking plate 14 receives pressure and slides each locking foot 12 vertically downward, the hook end 13 at the end of each locking foot 12 is formed. Expand outwardly, thereby creating an inward and upward resilient force. When each hook end 13 is passed through each perforation 21 of the heat sink 2, the hook end 13 at the end of each locking foot 12 is locked to the bottom surface of the heat sink 2 by the above-mentioned elastic force to form a fixing effect.

Meanwhile, the surface of the interlocking plate 14 is curved and formed in an arc shape, and its structural strength is enhanced. When the interlocking plate 14 receives pressure, the locking feet 12 on both sides are directed downward with sufficient strength. To slide.

[0012]

[Effect of the invention]

 As described above, the fastener 1 of the present invention is applicable to the combination of the CPU 3 and the heat sink 2 of the Celeron level of Intel Corporation, and the structure of the present invention is novel and practical. In addition, any modification or modification of details that can be made based on the present invention and which can achieve the same effect as the present invention shall fall within the scope of the claims of the present invention.
