PROBLEM TO BE SOLVED: To eliminate the creeping distance for insulation by locating the end of one plate conductor put between two plate insulators and a part projecting on the surface of a conductor of a connector for connecting a multilayer body made by alternately stacking plate conductors and plate insulators and an electric component, adjacently to each other, and covering the end of the plate conductor with an insulating material. SOLUTION: A multilayer conductor 5 is constituted of plate conductors 31, 32 and plate insulating materials 81-83, with the plate conductor 31 connecting the positive poles of capacitors 11, 12 to each other and the electrodes of the same polarity of a group of switches 21-23 to each other. The plate insulating materials 81-83 are located on the most upper face of the multilayer conductor 5, in the middle, and on the most lower face of the conductor 5, respectively, to insulate the plate conductors 31, 32. When tightening a connection member 55 from the most upper part of the multilayer conductor 5, the creeping distance from the end of the plate conductor 32 to the plate conductor 31 through the surface of the plate insulating material 82 becomes larger in proportion to the voltage applied between the plate conductors 31 and 32. Therefore, by covering the end of the plate conductor 32 in the inside of a hole of the conductor plate with an insulating material 9 made of such material as to stand the application voltage and in the thickness corresponding to the diameter of a connection member insertion hole, the plate conductor can be electrically insulated without necessitating the creeping distance for insulation. |
