Abstract
Abstract An electric elbow connector comprises an L-shaped hollow housing structure formed of insulating material and of semi-conducting material which contains an elongated contact sleeve having a hollow sleeve portion at one end and an integral shank at the other end, the shank having an outer end portion of substantially larger transverse dimension than its inner portion and the outer portion of the shank being of a hardness considerably greater than the hardness of the inner portion of the shank and of the hollow end portion of the contact sleeve, and a contact pin in electric contact with the hard outer end portion of the shank of the contact sleeve and disposed within the housing.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
104 words
An electric elbow connector comprising an elongated contact sleeve having a hollow sleeve portion at one end and an integral shank at the other end, said shank having an outer end portion and an inner portion, said inner portion of said shank being of a substantially smaller transverse dimension than said outer portion whereby said inner portion of said shank is rendered more readily deformable than said outer end portion, an electric conductor having an end portion disposed within said sleeve portion of said contact sleeve and secured therein, and a contact pin in electric contact with said outer end portion of said shank.
Claim 2
Dependent Claim
104 words
An electric elbow connector comprising an elongated contact sleeve having a hollow sleeve portion at one end and an integral shank at the other end, said shank having an outer end portion and an inner portion, said inner portion of said shank being of a substantially smaller transverse dimension than said outer portion whereby said inner portion of said shank is rendered more readily deformable than said outer end portion, an electric conductor having an end portion disposed within said sleeve portion of said contact sleeve and secured therein, and a contact pin in electric contact with said outer end portion of said shank.
Claim 3
Dependent Claim
79 words
An electric elbow according to claim 1 wherein a contact body having formed therein a pair of angularly related intersecting contact making passages in one of which the shank end of said contact sleeve is disposed and in the other of which an end of said contact pin is threadedly mounted in such manner that the end of said contact pin is in high pressure contact with the outer end portion of said shank end of said contact sleeve.
Claim 4
Dependent Claim
32 words
An electric elbow connector according to claim 1 wherein said outer end portion of said shank includes a transverse threaded aperture in which an end of said contact pin is threadedly mounted.
Claim 5
Dependent Claim
25 words
An electric elbow connector according to claim 1 wherein said contact sleeve is formed of aluminum and wherein said contact pin is formed of copper.
Claim 6
Dependent Claim
51 words
An electric elbow connector according to claim 1 wherein said contact sleeve is formed of substantially homogenous metal and wherein the hardness of said outer end portion of said shank is substantially greater than that of said inner portion of said shank and of said sleeve portion of said contact sleeve.
Claim 7
Dependent Claim
23 words

Claim 9
Dependent Claim
96 words
An electric elbow connector comprising an elongated contact sleeve having a hollow sleeve portion at one end and an integral shank at the other end, said shank having an outer end portion and an inner portion, said inner portion of said shank being of a substantially smaller transverse dimension than said outer end portion, and said contact sleeve being formed of substantially homogenous metal and the hardness of said outer end portion of said shank being substantially greater than that of said inner portion of said shank and of said sleeve portion of said contact sleeve.
Claim 10
Dependent Claim
96 words
An electric elbow connector comprising an elongated contact sleeve having a hollow sleeve portion at one end and an integral shank at the other end, said shank having an outer end portion and an inner portion, said inner portion of said shank being of a substantially smaller transverse dimension than said outer end portion, and said contact sleeve being formed of substantially homogenous metal and the hardness of said outer end portion of said shank being substantially greater than that of said inner portion of said shank and of said sleeve portion of said contact sleeve.
Claim 11
Dependent Claim
115 words
A contact sleeve for an electric elbow connector, said contact sleeve comprising an elongated cylindrical structure formed of aluminum and having a hollow sleeve portion at one end and an integral coaxial shank at the other end, said shank having an outer end portion and an inner portion, said inner portion of said shank being of a substantially smaller diameter than said outer end portion whereby said inner portion of said shank is rendered more readily deformable than said outer end portion, the minimum hardness of said outer end portion of said shank being approximately Rh70 and the maximum hardness of said inner portion of said shank and of said sleeve portion being approximately Rh45.
Claim 12
Dependent Claim
115 words
A contact sleeve for an electric elbow connector, said contact sleeve comprising an elongated cylindrical structure formed of aluminum and having a hollow sleeve portion at one end and an integral coaxial shank at the other end, said shank having an outer end portion and an inner portion, said inner portion of said shank being of a substantially smaller diameter than said outer end portion whereby said inner portion of said shank is rendered more readily deformable than said outer end portion, the minimum hardness of said outer end portion of said shank being approximately Rh70 and the maximum hardness of said inner portion of said shank and of said sleeve portion being approximately Rh45.
Claim 13
Dependent Claim
