Abstract:
1. A plug, comprising: a first conductor formed as a bar and having a first electrode portion and a first fitting portion; a first insulator outwardly fitted with the fitting portion of said first conductor; a second conductor outwardly fitted with said first insulator and having a second electrode portion and a second fitting portion, said second conductor being isolated from said first conductor by said first insulator; a second insulator outwardly fitted with the fitting portion of said second conductor; a third conductor outwardly fitted with said second insulator and having a third electrode portion and a third fitting portion, said third conductor being isolated from said second conductor by said second insulator; a third insulator outwardly fitted with the fitting portion of said third conductor; wherein the first, second, and third electrodes of said first, second and third conductors are formed with a diameter greater than that of the fitting portions; each of said first, second and third insulators individually have the fitting portions of said second and third conductors and said fourth conductor are outwardly fitted with the small diameter sections of said first, second and third insulators, respectively, a fourth conductor outwardly fitted with said third insulation portion and having a fourth electrode portion, said fourth conductor being isolated from said third conductor by said third insulator; a fourth insulator attached at least to a portion of the outer face of said fourth conductor; wherein said fourth insulator is formed for engagement with the large diameter portion of said third insulator; and a fifth conductor attached to said fourth insulator.
