Patent ID: 8025530

Claim:
An apparatus comprising: a wall portion having an opening therethrough, and having a first annular surface thereon that extends around said opening; a circuit board; an electrical connector supported on said circuit board, the electrical connector comprising: a second annular surface; a plurality of electrical contacts that each extend through said connector and have opposite ends disposed on opposite sides of said connector; and an overmold, the overmold being tightly molded around the contacts and having a coefficient of thermal expansion that is approximately equal to a coefficient of thermal expansion of the contacts, wherein: the overmold sealingly engages the contacts to prevent fluid flow therealong through said connector; a seal ring having third and fourth annular surfaces thereon that respectively engage said first and second annular surfaces; and structure cooperable with the wall portion and the connector in a manner compressing said seal ring between said first and second annular surfaces so that said seal ring effects a fluid seal between said first and second annular surfaces, said electrical connector and said seal ring preventing fluid flow through said opening from one side of said wall portion to the other side thereof, and said electrical contacts each having a portion that is accessible through said opening.
