发明名称 POWER SEMICONDUCTOR DEVICE
摘要 A power semiconductor device comprising a first housing having a cutout with an opening, and a second housing. The device has a load element having external and internal sections, and a feedthrough section pressing through the opening. The feedthrough section has a first outer edge region which tapers laterally towards a first outer edge thereof and a second outer edge region which tapers laterally towards a second outer edge thereof. The first and second outer edge regions face away from one another. The first outer edge is near the lateral first end of the opening and the second outer edge is near the lateral second end of the opening. A first seal is positioned between the first housing and the feedthrough section and a second seal is positioned between the second housing and the feedthrough section. The seals contact one another laterally from the first and second outer edges.

主权项 1. A power semiconductor device comprising: a housing with first and second housing parts, said first housing part having a first cutout, said first and second housing parts being configured to form an opening in said housing through said first cutout, said opening having lateral first and second ends; an electrically conductive load terminal element for permitting electrical contact with the power semiconductor device, said electrically conductive load terminal element having an external terminal section arranged outside said housing, an internal terminal section arranged inside said housing and a feedthrough section pressing through said opening, said feedthrough section having first and second outer edges, and first and second outer edge regions; a first sealing element having a first section which is arranged between said first housing part and said feedthrough section; and a second sealing element having a first section which is arranged between said second housing part and said feedthrough section; wherein said first and second sealing elements contact one another laterally from said first and second outer edges of said feedthrough section; wherein said first outer edge region tapers laterally in the direction of said first outer edge and said second outer edge region tapers laterally in the direction of said second outer edge; and wherein said first and second outer edge regions are disposed so as to face away from one another, said first outer edge is arranged proximate said lateral first end of said opening and said second outer edge is arranged proximate said lateral second end of said opening.
