Description

Fan connector with mechanism for positioning chip circuit board

The invention relates to a fan connector, and in particular, to a fan connector in which a chip circuit board with a control chip can be placed, and the chip circuit board can also be resisted by at least one resisting block.

In the current information technology environment, with the continuous development of the information industry and the continuous advancement of cloud technology and big data computing, the demand for data calculation and transmission has gradually increased. Therefore, various electronic devices (such as desktop Computers, laptops, servers, etc.) are all committed to improving their computing and storage capabilities to meet this challenge. However, the heat generated during the operation of the aforementioned electronic equipment has also become a technical problem to be solved, especially the high-performance central processing unit (CPU), which will generate a large amount of heat during operation. If it cannot be quickly and efficiently Efficiently dissipating heat may cause overheating of itself or adjacent components, thereby reducing service life and even causing damage or malfunction of electronic equipment.

In view of this, most electronic devices have adopted the method of installing fans inside to ensure that the electronic devices can operate normally at a stable temperature. Specifically, for desktop computer hosts, the fans configured inside are mainly Used to assist the CPU in cooling. However, this type of fan can only disperse the heat to the inside of the case but cannot completely discharge it to the outside. To solve this problem, most manufacturers will install additional fans on the front, back or side of the case to keep the CPU and motherboard The heat generated by the electronic components can be smoothly discharged to the outside, thereby ensuring the stability of the host during operation. In addition, cloud equipment (such as high-density servers) generates much more heat than ordinary electronic equipment due to its continuous operation and high computing requirements. Therefore, such equipment is usually equipped with a fan tray. It can generate strong air flow to quickly discharge the heat generated by internal components (such as hard drives, CPUs, graphics processing units (GPUs), memory modules, control boards, etc.) to the outside.

Although the existing technology has achieved certain results in heat dissipation, it still needs to be further optimized. The main reason is that the current operating mode of the fan needs to be adjusted according to the usage status of the electronic device. Therefore, the fan speed must be different in different situations. change. In addition, since the temperatures detected by fans at different locations may be different, the speed adjustment of each fan must be relatively independent. In this case, the applicant has developed a fan connector technology with a control chip. However, in actual operation, if the control chip is not pressed accurately, contact problems may occur, causing the fan connector to fail to transmit correctly. control signal; conversely, if the control chip is over-stressed, it may be damaged. It can be seen from this that the current fan connector technology is still insufficient, so how to propose an improved fan connector with a complete structure has become an important topic of this creation.

In view of the fact that the structure used in the existing fan connector still has room for improvement, the creators relied on years of practical experience to optimize the detailed structure of each part of the fan connector and after many experiments and research Finally, they finally designed a fan connector with a chip circuit board positioning mechanism, hoping to improve their market competitiveness.
