Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A swivel electrical connector comprising a tubular external conductor, a tubular internal conductor located internally of said external conductor in coaxial relation with respect thereto, an insulating material separating the conductors so that each forms part of a separate electrical circuit, a first conducting lead joined to said external conductor, a second conducting lead joined to said internal conductor, the insulating material defining a body that encapsulates the connections of said conducting leads to said conductors therein, said tubular internal conductor defining a socket for receiving a male conductor prong therein and said external conductor being exposed for engagement by a spring contact, wherein said body and conductors mounted thereon are swivally movable about the male prong as received in said internal conductor, said spring contact being maintained in continuous contact with said external conductor during the swivel movement thereof.
Claim 2
Dependent Claim
140 words
A swivel electrical connector comprising a tubular external conductor, a tubular internal conductor located internally of said external conductor in coaxial relation with respect thereto, an insulating material separating the conductors so that each forms part of a separate electrical circuit, a first conducting lead joined to said external conductor, a second conducting lead joined to said internal conductor, the insulating material defining a body that encapsulates the connections of said conducting leads to said conductors therein, said tubular internal conductor defining a socket for receiving a male conductor prong therein and said external conductor being exposed for engagement by a spring contact, wherein said body and conductors mounted thereon are swivally movable about the male prong as received in said internal conductor, said spring contact being maintained in continuous contact with said external conductor during the swivel movement thereof.
Claim 3
Dependent Claim
50 words
A swivel electrical connector as claimed in claim 1, said tubular external connector being foreshortened at least at the outer end thereof relative to the adjacent end of said internal conductor, said insulating material insulating the outer ends of said internal conductor from the outer end of said external conductor.
Claim 4
Dependent Claim
28 words
A swivel electrical connector as claimed in claim 1, the outermost end of said internal conductor having a flared configuration to provide a lead-in for said male prong.
Claim 5
Dependent Claim
63 words
A swivel electrical connector as claimed in claim 1, said body including a forward portion in which the connections of said conducting leads to said conductors are encapsulated, and a rear portion being integrally molded with said forward portion and having a section the axis of which is angularly disposed relative to said forward portion, thereby providing for easy handling of said connector.
Claim 6
Dependent Claim
34 words
A swivel electrical connector as claimed in claim 1, said internal and external conductors being defined as annular sleeves, the length of the internal conductor being greater than the length of said external conductor.
Claim 7
Dependent Claim
44 words
A swivel electrical connector as claimed in claim 5, the diameter of said external conductor being sufficiently greater than the diameter of said internal conductor to define a space therebetween in which the insulating material is received to insulate the conductors from each other.
