Abstract
A fuel injector includes first and second electrical actuators positioned within an injector body. First and second pairs of electrical conductors extend from a socket connector outside of the injector body to the first and second electrical actuators, respectively. The electrical conductors extend through an elastomeric sealing member that seals against fuel leakage from the fuel injector. The elastomeric sealing member provides annular sealing ridges in sealing contact with an access passage of the injector body and includes individual conductor seal passages that form seals around the outer surface of the individual electrical conductors. The elastomeric sealing member includes features that facilitate assembly of the fuel injector in a manner that reduces risk of damage to the sealing strategy.
