Abstract

The invention relates to a fixing structure of switching devices and relates to a power conversion device. The fixing structure comprises a bottom plate, a switching device positioning plate and a cover plate; the bottom plate and the switching device positioning plate are assembled together; the switching device positioning plate comprises a plurality of spacers; the spacers are located on the side, away from the bottom plate, of the switching device positioning plate; a plurality of switching device pin accommodating grooves are formed in the main body part of the switching device positioning plate between two adjacent spacers and are used for accommodating pins of switching devices; the cover plate is pressed on the switching device positioning plate so as to press the pins of the switching device in the switching device pin accommodating grooves, and therefore, a plurality of switching devices form a switching device module.

Description

technical field [0001] The invention relates to a power module, in particular to a fixing structure of a switching device. Background technique [0002] With the development of the automobile industry, the requirements for the miniaturization of auto parts are getting higher and higher, and the integration of parts is required to be higher and higher, so modular installation has become a common method. [0003] However, as an important power device of a charger in an automobile, switching devices are numerous in number and generate a large amount of heat. Therefore, the stable installation and heat dissipation of the switching device are important indicators of the charger. In addition, the installation position of the switch device needs to be controlled more accurately, otherwise problems such as too close distance or uneven pressing force may easily occur. [0004] see figure 1 , figure 1 It is a schematic diagram of a fixed structure of a switching device in the prio...
