Abstract

The invention relates to a power module terminal. The terminal comprises a connection part with elasticity, a main body part and a bend part for releasing stress, wherein the three parts are arranged from top to bottom; the upper part of the main body part is provided with a wing part; or the upper part and the lower part of the main body part are both provided with wing parts. The terminal adopts the connection part with the elasticity, the main body part and the bend part for releasing the stress, and can effectively buffer suffered thermal stress and mechanical stress through the bend part, so that the thermal stress and the mechanical stress of the terminal are reduced, the service life of a power module is prolonged, and the strength of the terminal is improved; and the terminal has a reasonable structure, can solve the fault problem due to excessive deformation caused by installation of each terminal, and is convenient to maintain the power module.

Description

technical field [0001] The invention relates to a power module terminal and its connecting structure, belonging to the technical field of power module manufacturing. Background technique [0002] The power semiconductor module is used in inverter welding machines, controllers of various switching power supplies, and electric vehicle controllers, etc. Its main function is to convert the input DC power into a three-phase AC output. The power semiconductor module is a three-phase circuit composed of one or more drive units and one or more power modules. Traditional power semiconductor modules mainly include resistors, capacitors, diodes, semiconductor chips and other devices, as well as multiple electrode terminals and multiple signal terminals. Each device and multiple terminals are welded on the metal-clad ceramic substrate to form the main circuit board. The main circuit board passes through Glue filling is sealed and fixed on the shell. In order to reduce the size of the ...
