A first electrical connector half has an electrical contact proximate therewith and is surrounded by a support structure. A second electrical connector half has an electrical contact proximate therewith and has a body segment and a mating segment within which extends an outer peripheral wall. Furthermore, the second connector half outer peripheral wall has an outside surface and an inside surface which are joined by a peripheral edge therearound. The sealing member is juxtapositioned between the inside surface of the second connector half and the outside surface of the first connector half supporting structure. ## Claims ### Claim 1 An electrical connector assembly for an automotive vehicle comprising: a first connector half having an electrical contact proximate therewith and being substantially surrounded by a support structure therearound, said support structure further having an outer surface thereof; a second connector half having an electrical contact proximate therewith, said second connector half further having a body segment and a mating segment within which extends an outer peripheral wall having an outside surface, an inside surface and a peripheral edge therearound, said body segment of said second connector half having a shoulder thereon such that said inside surface of said mating portion intersects said body at said shoulder thereto; and a sealing member having a pentagonal cross sectional shape thereto with an inside surface defining an aperture centrally therein, said pentagonal cross sectional shape having a substantially straight base wall with a pair of relatively shorter end walls projecting therefrom and having a pair of angular faces extending therefrom, said pair of angular faces intersecting each other at a peaked segment, said inside surface of said second connector half peripheral wall and said outer surface of said first connector half supporting structure having said sealing member juxtapositioned therebetween such that said peaked segment is compressed therein. ### Claim 2 (depends on 1) The electrical connector assembly of claim 1 wherein: said sealing member has an elongated annular shape thereof. ### Claim 3 (depends on 1) The electrical connector assembly of claim 1 wherein: said sealing member is made from an elastomeric material. ### Claim 4 (depends on 1) The electrical connector assembly of claim 1 wherein: said first connector half disengagably locks upon a portion of said second connector half. ### Claim 5 (depends on 1) The electrical connector assembly of claim 1 wherein: said shoulder of said second connector half has one of said pair of end walls of said sealing member adjacent thereto. ### Claim 6 (depends on 5) The electrical connector assembly of claim 5 wherein: said inside surface of said second connector half has said base wall of said sealing member proximate therewith; and said outer surface of said first connector half support structure has said peaked segment of said sealing member coincident therewith such that said peaked segment of said sealing member is compressed thereagainst. ### Claim 7 (depends on 6) The electrical connector assembly of claim 6 wherein: said inner surface of said second connector half externally guides said sealing member during installation of said connector halves. ### Claim 8 (depends on 5) The electrical connector assembly of claim 5 wherein: said outer surface of said first connector half support structure has said base wall of said sealing member proximate therewith; and said inside surface of said second connector half has said peaked segment of said sealing member coincident therewith such that said peaked segment of said sealing member is compressed thereagainst. ### Claim 9 (depends on 8) The electrical connector assembly of claim 8 wherein: said outer surface of said first connector half support structure internally guides said sealing member during installation of said connector halves. ### Claim 10 (depends on 1) The electrical connector assembly of claim 1 wherein: said sealing member has a plane defined by said base wall and each of said pair of angular faces thereby forming a pair of predetermined angles therebetween, said predetermined angles each are symmetrical with one another. ### Claim 11 (depends on 10) The electrical connector assembly of claim 10 wherein: said pair of predetermined angles between said pair of angular faces and said base wall plane fall within a range of 15-30 degrees. ### Claim 12 A seal for an automotive electrical connector assembly being comprised of: a pentagonal cross sectional shape with an inside surface defining an aperture centrally therein, said pentagonal cross sectional shape having a substantially straight base wall with a pair of relatively shorter end walls projecting therefrom and having a pair of angular faces extending therefrom, said pair of angular faces intersecting each other at a peaked segment. ### Claim 13 (depends on 12) The seal of claim 12 wherein: said seal has an elongated annular shape thereof. ### Claim 14 (depends on 12) The seal of claim 12 wherein: said seal is made from an elastomeric material. ### Claim 15 (depends on 12) The seal of claim 12 wherein: said seal has a plane defined by said base wall and each of said pair of angular faces thereby forming a pair of predetermined angles therebetween, said predetermined angles each are symmetrical with one another. ### Claim 16 (depends on 15) The seal of claim 15 wherein: said pair of predetermined angles between said pair of angular faces and said base wall plane fall within a range of 15-30 degrees.
