<p>A mounting clip used for fitting a heat sink to a CPU or MPU. Conventional clips involve problems that they tend to come off due to drop or vibration, the CPU or MPU may break internally due to heat expansion, and the total cost of a double-sided type is inevitably high. In order to solve such problems, a detachment preventing clip has been developed. Since this clip is obliquely attached along a diagonal line to a heat sink and simultaneously fixes the fin section of the heat sink in four directions with fixing claws (1-d) in such a way as to hold the whole body of the sink from above, the clip can prevent detachment of any heat sink regardless of its size, if the size of the fin section is equal to that of the claws. In addition, the fixing forces of the claws (1-d) are strong, since the upper sections of clip slightly curve upward. Since foreign matters are inserted into the voids of mounting holes (see fig. 2) after mounting a heat sink, coming off of the clip can be prevented. Using this, a coming off preventing pin (1-a) has been devised. The pin (1-a) can be automatically inserted into the mounting holes, when a small hook (1-c) is used at the central part of the clip and holes (3-a) or bracing guides (3-b) are provided at both ends of the clip (see fig. 3).</p> |
