Description

Technical Field

[0001] The utility model belongs to the technical field of computer components, and more specifically, particularly relates to an anti-detachment backplane installation structure for a CPU radiator. Background Art

[0002] As the operation and control core of a computer system, the CPU generates a large amount of heat during operation. If the heat is not dissipated in time, it will affect the normal operation and smoothness of the computer system. Therefore, a separate radiator needs to be set for the CPU to dissipate heat.

[0003] When installing the existing CPU radiator, it is usually fixed by means of a backplane and fasteners; when installing the backplane, the studs at its four corners are usually aligned and inserted into the installation through holes on the motherboard, and then the isolation posts and fasteners are sequentially sleeved on the protruding ends of the studs from the other side of the motherboard, and then nuts are screwed onto the tops of the studs to tighten the fasteners; since the isolation posts and studs are directly sleeved and connected, that is, during actual installation, the isolation posts are prone to displacement or even separation from the screw rods, resulting in the separation of the screw rods and the backplane from the motherboard, affecting the overall installation efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an anti-detachment backplane installation structure for a CPU radiator is provided, in order to achieve a more practical value purpose. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides an anti-detachment backplane installation structure for a CPU radiator, which is achieved by the following specific technical means:

[0006] An anti-detachment backplane installation structure for a CPU radiator includes a backplane and isolation posts. Anti-detachment buckles are installed at the four corners of the backplane. Studs are vertically and fixedly installed at the tops of the anti-detachment buckles. The tops of the studs penetrate through the installation through holes of the motherboard. External thread one is provided on the outer side of the top of the studs, and external thread two is provided on the outer side of the middle section of the studs; a threaded hole is vertically penetrated through the isolation post, and the threaded hole can be matched and connected with the external thread two.

[0007] Further, the stud is divided into upper and lower sections, and the diameter of the upper section is smaller than that of the lower section; the external thread one is provided on the outer side of the top of the upper section, and the external thread two is provided on the outer side of the top of the lower section.

[0008] Further, the nominal diameter of the external thread two is larger than that of the external thread one.

[0009] Further, multiple groups of anti-slip grooves are equiangularly arranged on the outer side of the isolation post.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] By arranging a threaded hole in the isolation column that matches the external thread two on the outer side of the stud, the utility model can achieve stable connection of the isolation column to the outer side of the stud during installation and press the main board tightly, preventing displacement and detachment of the isolation column and the stud when installing the buckle, enabling users to install the buckle and radiator more easily and conveniently, and effectively improving the overall installation efficiency. At the same time, setting the nominal diameter of the external thread two to be larger than that of the external thread one facilitates the rapid passing of the isolation column through the external thread one and connection with the external thread two, thereby improving the installation efficiency of the isolation column and having high usability.
