Description

Fixtures for power supplies

technical field

The utility model relates to a fixing technology, in more detail, relates to a fixing device for fixing a power supply to a housing of an electronic device.

Background technique

With the improvement of industrial technology and the division of labor, the manufacture of a single product usually goes through many different production processes, such as component manufacturing, assembly, testing, packaging, etc., especially for electronic products.

With the continuous increase of data processing volume and the higher and higher requirements of users for real-time processing, multi-processor computers such as servers are more and more widely used. Due to the use of multiple processors, the server will require internal processing when running. A pluggable power supply is installed to meet the needs. However, manufacturers of electronic equipment currently on the market, such as server chassis, manufacture various product models according to different specifications, so that each model can be installed and fixed with a pluggable power supply. The means of pulling out the power supply are different. In the fixed structure design of the chassis and the power supply box, it is more common to use screws as the fixing parts to lock the power supply box and the chassis.

However, in the fixing technology using screws, it is necessary to select a tool (screwdriver) corresponding to the size of the screw to perform the screw locking work. When installing or maintaining electronic products with many parts of different sizes, it is necessary to change the tools frequently. A lot of inconvenience, especially for the parts with dense parts, it is difficult to operate the screw lock or unscrew, etc., and even special special tools must be designed to provide operations. Therefore, the fixing technology using screws does have the disadvantages of inconvenient operation and time-consuming. Moreover, once the screws are automatically loosened due to loose fixation and fall to the circuit board in the chassis, it will definitely affect the normal operation of the circuit board. What's more, the circuit board will be short-circuited because the screws are connected to different lines, resulting in The problem of burning out the circuit board.

Furthermore, since the side walls of the chassis and the power supply box are both relatively thin, in order to fasten screws thereon, not only the cumbersome procedures of sprouting and tapping the thinner side walls are required. At the same time, the application of this existing technology also requires strict selection of screws for side wall locking, which usually need to be manufactured separately, and the length of the selected screws and the height of sprouting need to be precisely controlled; once an error occurs, it will not cause the screw to lock. If the fixing strength is not firm enough, the reason why the screw is too long will scratch the power supply inside the box through the side wall of the power supply box and affect the assembly quality. Therefore, the existing technology of using screw locks to fix the chassis and power supply is not only not conducive to processing and assembly, but also affects the assembly quality and fixing strength, and relatively increases the cost, so it is extremely inconvenient to use.

Therefore, how to design a power supply fixing technology that can eliminate screws, facilitate installation and disassembly, and improve assembly quality, so as to avoid the above-mentioned defects, is an urgent problem to be solved by operators in related fields.
