Description

A CPU backplane structure

Technical field:

The utility model relates to the technical field of computer accessories, in particular to a CPU backboard.

Background technique:

When the CPU is installed on the PCB main board, a backplane needs to be attached to the back of the PCB main board to meet the installation requirements of the CPU and its cooling components. Traditional CPU backplanes have the following problems: either they are bulky and expensive to manufacture; or they are not strong enough in structure and easily distorted, so it is necessary to improve them.

In view of the lack and inconvenience of the above-mentioned conventional CPU backplane structure, the applicant adheres to the spirit of research, innovation and excellence, and uses his professional vision and professional knowledge to develop a CPU that has a wide range of applications and meets the value of industrial utilization. backplane.

Invention content:

The purpose of the utility model is to provide a CPU backboard structure with good structural strength, light and small body shape and convenient installation.

In order to achieve the above object, the utility model adopts the following technical solutions:

A CPU backplane structure, the backplane is formed with concavo-convex parts in the form of ribs, and the concavity and convexity directions of the concavo-convex parts are corresponding on the front and back surfaces of the backplane.

Several screw holes are also provided on the back plate, and a boss is protruded from one end of the screw hole to adapt to the installation of the PCB main board. The boss is circular and is integrally stamped and formed with the back plate.

The backplane is installed on the back of the PCB mainboard, and an insulating rubber pad is embedded between the backplane and the PCB mainboard. The bosses on the backplane are correspondingly inserted into the through holes of the PCB mainboard, and the bosses are covered with rings; It is made by stretching and forming the insulating rubber pad, which is inserted into the through hole of the PCB main board after being socketed with the boss.

The utility model can enhance the structural strength of the backboard by forming concave-convex parts in the form of ribs on the backboard, which is not easily deformed, and can effectively reduce the thickness of the backboard, save production costs, and improve the usability and durability of the backboard. economy.

Another advantage of the utility model is that a boss is provided on one end of the screw hole of the back plate to adapt to the installation of the PCB main board, and has the function of positioning and installation, improving the convenience and accuracy of installation.

Detailed ways:

In order to enable the review committee to have a further understanding of the purpose, features and functions of the present utility model, the preferred embodiments are hereby given in detail with the accompanying drawings as follows:

First please refer to Fig. 1, which is a schematic structural view of a preferred embodiment of the present invention. The present invention is related to the CPU backplane structure. The backplane 10 is formed with concave-convex parts 11, and the concave-convex parts 11 are in the form of ribs. , in the middle of the backboard 10, the design is parallel, and the concave-convex direction of the concave-convex part is corresponding on the front and back of the backplane. The structure of the concavo-convex part 11 can relatively increase the structural strength of the backplane, making it less likely to be twisted and deformed, improving the usability of the backplane, thereby meeting the installation strength requirements of the CPU and its cooling components. By designing the concavo-convex part 11, when the required structural strength is achieved, the thickness of the backboard can be relatively reduced, saving materials and reducing manufacturing costs, and the backboard is compact and light.

As shown in FIG. 1 , several screw holes 12 are also provided on the back plate to cooperate with the CPU bracket screw installation, and a boss 13 is protruded from one end of the screw hole 12 to adapt to the installation of the PCB main board 20 . The boss 13 is circular and is integrally punched and formed with the back plate.

As shown in Figures 2, 3 and 4, during implementation, the backplane 10 is installed on the back of the PCB mainboard 20, and the CPU bracket 50 is installed on the front of the PCB mainboard 20, and an insulating rubber pad is embedded between the backplane 10 and the PCB mainboard 20 30 , the boss 13 on the backplane 10 is correspondingly inserted into the through hole 21 of the PCB main board 20 , and the boss 13 is covered with a collar 40 to form a good positioning fit with the through hole 21 . In this embodiment, the ring sleeve 40 is directly stretched and formed by the insulating rubber pad 30 , which not only saves cost effectively, but also optimizes the assembly structure to achieve the effect of convenient assembly.

After assembly, the backplane 10 is closely attached to the back of the PCB main board 20 to match the installation of the CPU and its heat dissipation components. The concave and convex parts 11 on the backplane strongly enhance the structural strength of the backplane, which can withstand a large load and is not easy to twist Deformation, the backboard is light and small in size, and the installation is quite convenient, which improves the usability and economy of the backboard.
