Abstract
Abstract A high-voltage wiring connection structure having first and second insulating members fitted with one another and protecting an electrical connection portion disposed within at least one of the first and second insulating members. A layer of a soft elastic silicone resin is provided on a surface of at least the two insulating members in contact with a mating surface of the other of the insulating members. An improved sealing effect, with reduced arcing and improved reliability, is thereby attained.
