Claim:
1. A package structure of a power module, the package structure comprising: an insulation frame comprising a sidewall, a first opening end, a second opening end and at least one first coupling part, wherein the at least one first coupling part is externally protruded from the sidewall, and the first coupling part comprises a first mounting structure; a first circuit substrate combined with a bottom part of the insulation frame, wherein the first opening end is covered by the first circuit substrate; an insulation cover combined with a top part of the insulation frame, wherein the second opening end is covered by the insulation cover, and an accommodation space is defined by the insulation cover, the insulation frame and the first circuit substrate collaboratively, wherein the insulation cover comprises a strut and at least one second coupling part, wherein the strut is protruded from a bottom surface of the insulation cover and located near the first circuit substrate or contacted with the first circuit substrate, wherein the at least one second coupling part is aligned with the at least one first coupling part of the insulation frame, and the second coupling part comprises a second mounting structure; plural first pins electrically connected with the first circuit substrate, wherein the plural first pins are embedded in the sidewall of the insulation frame and partially penetrated through the insulation cover; plural posts embedded in the at least one first coupling part of the insulation frame, and partially penetrated through the at least one second coupling part of the insulation cover; and at least one fastening element connected with the first mounting structure of the insulation frame and the second mounting structure of the insulation cover, so that the insulation frame and the insulation cover are combined together.
