ABSTRACT:
An inflator (26) provides inflation fluid for inflating an inflatable vehicle occupant protection device (24). The inflator (26) comprises an electrically conductive container (64) defining a chamber (66) for holding fluid at a first pressure. An electrically actuatable device (48) is located in the chamber (66) for effecting a change in the pressure of the fluid in the chamber to a second pressure greater than the first pressure. A first surface (206) defines a tapered portion (202) of a passage (200) extending through the container (64). An electrical conduit (220) extends through the tapered portion (202) to deliver electrical energy to the electrically actuatable device (48). The electrical conduit (220) has opposite connector ends (224, 226) and a tapered body (222) contacting the first surface (206) to provide a fluid seal. One connector end is located in the chamber (66) and is electrically connectable with the electrically actuatable device (48). The other connector end (226) is located outside of the chamber (66) and is electrically connectable with a source of electrical power (42). Anodic coating (240) is located on at least one of the first surface (206) and the tapered body (222) to provide electrical insulation between the container (64) and the electrical conduit (220).
