摘要： A package structure and its related electricity supply system are disclosed. Two substrates of the package structure are directly or indirectly served as current collectors of the electricity supply system. The sealing frame of the package structure is made of several silicone layers having high moisture-resistance and/or high gas-resistance. Hence, the package structure mentioned may not only provide a novel electrical conduction module to lower the intrinsic impedance of the electricity supply system itself but prevent the moisture and the gas outward from the electricity supply unit inside the package structure as well. Consequently, the electrical performance and safety of the electricity supply system are both improved.

摘要： To provide a fastening structure including an insulation member disposed between a fastening member and a fastened member, and having a configuration wherein the insulation member is in close contact with the fastening member and the fastened member so that an adequate sealing area is secured. According to one embodiment of the present invention for achieving the above object, a fastening structure includes: a case; a fastening member extending through a through hole formed in the case; and an insulation member disposed between the fastening member and the case. The fastening member includes an exposure portion exposed from the case, and a penetrating portion extending through the through hole. The exposure portion includes a confronting surface opposed to an outside surface of the case via the insulation member. A compression region defining a minimum distance between the confronting surface and the outside surface is provided at one location between the confronting surface and the outside surface. A projection projecting toward the outside surface from the confronting surface or projecting toward the confronting surface from the outside surface is disposed at place not overlapping with the compression region.
