Waterproof electrical connector

An electrical connector comprising:

• an electrical contact housing having a first end and a second end with at least one bore extending between said first and second ends;
• at least one electrical contact being retained within said bore of said electrical contact housing;
• an outer casing including an attachment portion fixedly coupled to said first end of said electrical contact housing and a tubular portion radially spaced from said second end of said electrical contact housing to form an annular space between an inner surface of said tubular portion and said second end of said electrical contact housing, said tubular portion of said outer casing having an inwardly extending protrusion with an abutment surface that faces away from said second end of said electrical contact housing;
• and
• an annular sealing member formed of a resilient and compressible material that is located in said annular space, said outer casing being molded about said annular sealing member to retain said annular sealing member in said tubular portion of said outer casing.

An electrical connector comprising:

• at least one electrical contact being retained within said bore of said electrical contact housing;
• an outer casing including an attachment portion fixedly coupled to said first end of said electrical contact housing and a tubular portion radially spaced from said second end of said electrical contact housing to form an annular space between an inner surface of said tubular portion and said second end of said electrical contact housing, said tubular portion of said outer casing having an inwardly extending protrusion with an abutment surface that faces away from said second end of said electrical contact housing;
• and
• an annular sealing member formed of a resilient and compressible material that is located in said annular space, said annular sealing member being an O-ring having at least half embedded in said tubular portion of said outer casing.

An electrical connector comprising:

• an electrical contact housing having a first end and a second end with at least one bore extending between said first and second ends;
• at least one electrical contact being retained within said bore of said electrical contact housing;
• an outer casing including an attachment portion fixedly coupled to said first end of said electrical contact housing and a tubular portion radially spaced from said second end of said electrical contact housing to form an annular space between an inner surface of said tubular portion and said second end of said electrical contact housing, said tubular portion of said outer casing having an inwardly extending protrusion with an abutment surface that faces away from said second end of said electrical contact housing;
• and
• an annular sealing member formed of a resilient and compressible material that is located in said annular space, said annular sealing member contacting said inner surface of said tubular portion of said outer casing and an opposed surface of said electrical contact housing.

An electrical connector comprising:

• an electrical contact housing having a first end and a second end with at least one bore extending between said first and second ends;
• at least one electrical contact being retained within said bore of said electrical contact housing;
• an outer casing including an attachment portion fixedly coupled to said first end of said electrical contact housing and a tubular portion radially spaced from said second end of said electrical contact housing to form an annular space between an inner surface of said tubular portion and said second end of said electrical contact housing, said tubular portion of said outer casing having an inwardly extending protrusion with an abutment surface that faces away from said second end of said electrical contact housing, said tubular portion of said outer casing including an inner part formed of a resilient and compressible material and a substantially rigid sleeve slideably overlying said inner part, said inner part including said inner surface of said tubular portion of said outer casing;
• and
• an annular sealing member formed of a resilient and compressible material that is located in said annular space, said annular sealing member and said inner part being formed as a one-piece, unitary member.

An electrical connector assembly comprising:

• a first electrical connector including
• a first electrical contact housing having a first end and a second end with at least one bore extending between said first and second ends and;
• at least one first electrical contact being retained within said bore of said first electrical contact housing;
• an outer casing including an attachment portion fixedly coupled to said first end of said first electrical contact housing and a first tubular portion radially spaced from said second end of said first electrical contact housing to form an annular space between an inner surface of said first tubular portion and said second end of said first electrical contact housing, said tubular portion of said outer casing having an inwardly extending first annular protrusion with an axial abutment surface that faces away from said second end of said first electrical contact housing, said outer casing including at least a substantially rigid sleeve;
• and
• an annular sealing member formed of a resilient and compressible material that is located in said annular space and fixedly coupled to said first tubular portion of said outer casing;
• and
• a second electrical connector including
• a second electrical contact housing having a body portion and a second tubular portion having a cylindrical outer surface with a second annular protrusion, said second tubular portion being dimensioned to be received within said annular space of said first electrical connector such that said first and second annular protrusions engage each other to form a snap fit connection therebetween and such that said annular sealing member is compressed by said second tubular portion;
• and
• at least one second electrical contact being retained within said body portion of said second electrical contact housing such that said second electrical contact mates with said first electrical contact when said first and second electrical contact housings are coupled together.
