The invention provides a half-bridge module for a power converter of an electric vehicle drive system. The half-bridge module can include a thermal interface having a mating member. The half-bridge module can include a first switching device that can be provided over a first surface of the thermal interface. The half-bridge module can include a clip having a first spring arm and a second spring arm. The first spring arm can be provided next to the first switching device and the second spring arm can be provided next to a second surface of the thermal interface. The clip can include an orificeformed to receive the mating member of the thermal interface. The clip can change from a first state to a second state in response to contact from the mating member of the thermal interface to the clip that is greater than a force threshold.
本文提供了一种用于电动车辆驱动系统的功率转换器的半桥模块。该半桥模块可以包括具有配合构件的热界面。该半桥模块可以包括第一开关器件,该第一开关器件可以设置在热界面的第一表面之上。该半桥模块可以包括具有第一弹簧臂和第二弹簧臂的夹具。第一弹簧臂可以设置为靠近第一开关器件,第二弹簧臂可以设置为靠近热界面的第二表面。该夹具可以包括孔口,该孔口形成为接收热界面的配合构件。该夹具可以响应于从热界面的配合构件到该夹具的大于力阈值的接触而从第一状态改变到第二状态。
