Abstract

The invention discloses an IGBT pin switching device and a power assembly. The IGBT pin switching device comprises a switching pin, the switching pin comprises a mounting part used for being connected with an IGBT pin and a free end part used for being connected with an external assembly, and the free end part is conductively connected with the mounting part. When the IGBT pin cannot be connected with the external assembly, the switching pin is installed on the IGBT pin, and the IGBT pin is conductively connected with the switching pin, so the length of the IGBT pin is increased through the switching pin, and the IGBT pin is electrically connected with the external assembly. According to the IGBT pin switching device provided by the invention, the switching pin which can be connected with the IGBT pin is arranged, so the connection length of the IGBT pin is increased, and the IGBT pin can be connected with an external assembly under the condition that the length of the IGBT pin is not enough.

Description

technical field [0001] The invention relates to the technical field of power device packaging, in particular to an IGBT pin transfer device. The present invention also relates to a power assembly comprising the above-mentioned IGBT pin switching device. Background technique [0002] In the discrete device IGBT, the surface of the IGBT is packaged in a plastic case, and the shrapnel is usually used to directly crimp the plastic case of the IGBT component. However, it is easy to cause local stress concentration on the IGBT, which may cause damage or affect the life of the IGBT. At the same time, the IGBT components extend out of the IGBT pins. Since the size of the IGBT pins is determined, they will be bent and cut according to the actual application. [0003] However, when the distance between the IGBT pins and the external components is far, the electrical connection cannot be realized. [0004] Therefore, how to extend the IGBT pin size of the IGBT component is a technica...
