Description

Technical Field

[0001] The utility model relates to the technical field of DC power modules, and specifically relates to a packaging structure of a DC-DC power module. Background Art

[0002] A power module is a power supply that can be directly mounted on a printed circuit board, and there are two types: step-down and step-up. Its characteristic is that it can supply power to application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field-programmable gate arrays (FPGAs), and other digital or analog loads.

[0003] The utility model with the existing publication number CN218416994U discloses a protection box for a DC-DC power module, which includes a packaging module, pins electrically connected to the bottom of the packaging module, and a protective cover sleeved on the surface of the packaging module. In the utility model, the pins at the bottom of the packaging module are inserted into the inside of the circuit board, and then the protective cover is sleeved on the surface of the packaging module. When the bottom of the protective cover contacts the surface of the circuit board, a tool is used to rotate the bolt, and the bolt uses the thread to push the driving plate to descend. The driving plate uses the trapezoidal block to push the pressing plate to rotate around the pin shaft inside the connecting block. When the inner side of the pressing plate contacts the surface of the packaging module, the pressing installation of the protective cover is completed, which can play a sealing and protective effect on the packaging module, and solves the problem that the existing power module is generally directly plugged on the surface of the circuit board and is prone to damage and short circuit when affected by the external environment.

[0004] In the above technical solution, the inventor at least found the following problem: When fixing the packaging module, it is necessary for the staff to use external tools to rotate the bolt to fix the packaging module, and the operation is relatively troublesome. Therefore, how to design a packaging structure of a DC-DC power module has become the problem that needs to be solved currently. Summary of the Utility Model
