Abstract
Abstract A water-resistant, insulated electrical connector for maintaining a secure connection therebetween to ensure uninterrupted current flow between male and female endpieces. The male endpiece features a double cylinder base with at least one O-ring and an annular groove. Electrical prongs project from the end of the male endpiece. The female endpiece has a lip at one end and features a cylindrical base, a cylindrical enclosure and a spring-biased sleeve which slidably engages the cylindrical base. The sleeve is manually retractable. A plurality of balls are loosely retained within and protrude from respective cavities defined by the inner surface of the cylindrical enclosure in an annular formation. The female endpiece defines sockets to receive the electrical prongs in well known fashion. Coupling of the male and female endpieces enables the insertion of the prongs into their respective sockets. The sleeve is then manually displaced toward the male endpiece, ultimately causing the balls to insertably engage the annular groove and lock into place to releasably secure the male and female endpieces together. The O-ring structure of the device enables a secure water-resistant seal. The lip, having been slid over and deposed past the O-ring, further secures the male and female endpieces together. Manually displacing the sleeve in the opposite direction disengages the balls from the annular groove to uncouple the male and female endpieces.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
A water-resistant electrical connector comprising: a male endpiece comprising cylindrical first and second portions, said first portion having a smaller diameter than said second portion and integrally connected thereto in an end-to-end formation, and said first portion incorporating plug contact elements and exterior surface articulating means for establishing and maintaining a water-resistant seal; and a female endpiece comprising a cylindrical member and a cylindrical sleeve, said cylindrical sleeve slidably engaging said cylindrical member, said cylindrical member incorporating socket means for receiving said plug contact elements of said male endpiece and a lip member circumferentially engaging one end thereof, and said cylindrical sleeve comprising interior surface articulating means for establishing and maintaining a water-resistant seal with said male endpiece, wherein said female endpiece defines a substantially cylindrical enclosure, said cylindrical enclosure having dimensions as to allow the insertion of a first cylindrical member therein and a surface defining a plurality of cavities in an annular formation, said cavities loosely retaining a plurality of balls, wherein said cylindrical sleeve has an annular groove, said annular groove accommodating said balls when aligned with said cavities, thus to enable disengagement between said male and said female endpieces.
Claim 2
Dependent Claim
193 words
A water-resistant electrical connector comprising: a male endpiece comprising cylindrical first and second portions, said first portion having a smaller diameter than said second portion and integrally connected thereto in an end-to-end formation, and said first portion incorporating plug contact elements and exterior surface articulating means for establishing and maintaining a water-resistant seal; and a female endpiece comprising a cylindrical member and a cylindrical sleeve, said cylindrical sleeve slidably engaging said cylindrical member, said cylindrical member incorporating socket means for receiving said plug contact elements of said male endpiece and a lip member circumferentially engaging one end thereof, and said cylindrical sleeve comprising interior surface articulating means for establishing and maintaining a water-resistant seal with said male endpiece, wherein said female endpiece defines a substantially cylindrical enclosure, said cylindrical enclosure having dimensions as to allow the insertion of a first cylindrical member therein and a surface defining a plurality of cavities in an annular formation, said cavities loosely retaining a plurality of balls, wherein said cylindrical sleeve has an annular groove, said annular groove accommodating said balls when aligned with said cavities, thus to enable disengagement between said male and said female endpieces.
Claim 3
Dependent Claim
41 words
The water-resistant electrical connector according to claim 1, wherein said exterior surface articulating means for establishing and maintaining a water-resistant seal include at least one O-ring seal, spaced apart and circumferentially disposed on said first portion, as well as said lip.
Claim 4
Dependent Claim
39 words
The water-resistant electrical connector according to claim 1, wherein said exterior surface articulating means for establishing and maintaining a water-resistant seal include two O-ring seals, spaced apart and circumferentially disposed on said first portion, as well as said lip.
Claim 5
Dependent Claim
37 words
The water-resistant electrical connector according to claim 3, wherein said interior surface articulating means for establishing and maintaining a water-resistant seal further include means defining a circumferential groove on said first portion, located between said O-ring seals.
Claim 6
Dependent Claim
60 words
The water-resistant electrical connector according to claim 1, wherein said female endpiece further comprises an annular cavity and a cylindrical spring, said annular cavity defined by and disposed between said cylindrical sleeve and said cylindrical member, and said cylindrical spring contained within said annular cavity and oriented parallel to said cylindrical member, whereby said cylindrical spring biases said cylindrical sleeve.
Claim 7
Dependent Claim
45 words
The water-resistant electrical connector according to claim 1, further comprising electrical cords operably engaging said male endpiece and said female endpiece, with connecting means for operably securing an electrical cord to said male endpiece and for operably securing an electrical cord to said female endpiece.
Claim 8
Dependent Claim
105 words
The water-resistant electrical connector according to claim 6, wherein said connecting means for operably securing an electrical cord to said male endpiece and for operably securing and electrical cord to said female endpieces comprises a frusto-conical end comprising a large opening, a small opening and two opposing half shells with means for securing said half shells together, whereby the large opening of said frusto-conical end circumferentially engages said male or said female endpiece, and said small opening engages an electrical cord, said half shells directing current-conveying wires from an electrical cord through to said male or said female endpiece to operably engage electrical components therein.
