Problems solved by technology

Among them, when this kind of screw is used, the washer needs to be assembled by special tools or labor, which increases the production cost
Moreover, after the screws are pre-assembled on the fasteners, there may be large vibrations in the fixing device during transportation, which may cause the gasket to deform and fall off, causing inconvenience

Embodiment Construction

[0019] see figure 1 and figure 2 , is an electronic device 10 provided by an embodiment of the present invention, which includes a housing 13, a heat sink 20 accommodated inside the housing 13, and a fixing device for fixing the heat sink 20 inside the housing 13 50.

[0020] The housing 13 includes a rectangular bottom plate 12 and a top plate 11 opposite to the bottom plate 12 . The top plate 11 and the bottom plate 12 are parallel to each other. A corner of the bottom plate 12 extends vertically toward the direction of the top plate 11 to form a fixing column 14 . A threaded hole 140 is defined in the center of the fixing column 14 , and a plurality of internal threads are formed in the inner surface thereof. A corner of the top plate 11 is provided with a circular depression at a place facing the fixing column 14 . The plate body 110 in the recess of the top plate 11 has a relatively small thickness, and the center of the plate body 110 is provided with a through hol...

Abstract

The invention relates to a fixed element, which comprises a head part and a screw rod extending from the head part. A flange extending towards an external radial direction from an outer surface is formed at one end close to the head part of the screw rod; a neck part is arranged between the flange and the head part; and the external diameter of the flange is changed along the extending direction of the screw rod. Due to the arrangement of the flange, the fixed element is pre-assembled on an object without a gasket and other extra elements when the object is connected to another object by the fixed element, and the fixed element can be screwed with the another object during assembly. Therefore, the fixed element is convenient to install, and the material cost and the assembly cost are saved. The invention also provides a fixed device and an electric device applying the fixed element.

Description

technical field [0001] The invention relates to a fixing part, a fixing device and an electronic device using the fixing part. Background technique [0002] With the rapid development of the computer industry, the operating capabilities of central processing units and other electronic components continue to improve, and their heat generation is also increasing. Heat dissipation has become a problem that must be solved when these heat-generating electronic components are used. At present, the solution commonly adopted in the industry is to install a heat sink on the electronic components to dissipate heat. When the heat sink is installed, it needs to be fixed on the electronic components with a fixing device. The effect of this fixing device will directly affect the heat sink and The heat exchange efficiency between electronic components affects the heat dissipation effect. [0003] Among them, screws are commonly used connections and fasteners in fixing devices. The screw ...
