一种功率半导体绝缘拉杆和压紧装置及其组装方法
摘要：
本发明公开了一种功率半导体绝缘拉杆和压紧装置及其组装方法，包括绝缘拉杆主体，受力固定端，沉头通孔和螺母，绝缘拉杆主体是功率半导体绝缘拉杆的主要受力部位，受力固定端位于绝缘拉杆主体的两端，用于对功率半导体绝缘拉杆进行连接固定，至少两个沉头通孔分别位于功率半导体绝缘拉杆的两个受力固定端，用于功率半导体绝缘拉杆与功率半导体压紧装置之间的固定，至少两个螺母分别位于功率半导体绝缘拉杆的两个受力固定端，用于功率半导体绝缘拉杆与外界的安装平台之间的固定。通过应用本发明所描述的技术方案，能够满足功率半导体器件压力需求和各电压等级结构绝缘的问题，同时还能解决环境温度对绝缘拉杆造成的热胀冷缩变形量大的问题。
摘要（英）：

The invention discloses an insulated pull rod and a pressing device for a power semiconductor, as well as an assembly method of the pressing device. The insulated pull rod comprises the main body of the insulated pull rod, force-bearing fixing ends, at least two countersunk through holes and at least two nuts, wherein the main body of the insulated pull rod is a main force bearing part of the insulated pull rod for the power semiconductor; the force-bearing fixing ends are located at two ends of the main body of the insulated pull rod for fixing the insulated pull rod for the power semiconductor; the countersunk through holes are located at the force-bearing fixing ends of the insulated pull rod for the power semiconductor and used for fixing the insulated pull rod for the power semiconductor and the pressing device for the power semiconductor; and the two nuts are located at the force-bearing fixing ends of the insulated pull rod for the power semiconductor and used for fixing the insulated pull rod for the power semiconductor and an external installation platform. Due to the adoption of the technical scheme disclosed by the invention, pressure requirements of power semiconductordevices, as well as insulation requirements of each voltage grade structure can be met, and the problem of the insulated pull rod which has great deformation in the case of thermal expansion and coldcontraction, caused by ambient temperature, can be solved.
