Abstract
Abstract An electric elbow connector includes a generally L-shaped hollow enclosing structure having a generally L-shaped conducting structure mounted therein and formed of three pieces including a contact body having formed therein a pair of angularly related contact making passages in one of which the shank end of a contact sleeve is disposed and in the other of which a contact pin is threadedly mounted in such manner that the end thereof is disposed in high pressure contact with the side of the shank of the contact sleeve. The pressure applied to the shank of the contact sleeve by the contact pin is insufficient to exceed the elastic limit of the contact body but is sufficiently great to impart deformation thereto whereby a springlike action is achieved resulting in substantially constant contact pressure between the contact body and the shank of the contact sleeve and between the contact pin and the contact body as well as between the contact pin and the side of the shank of the contact sleeve. An electric conductor is interconnected with the contact sleeve in known manner and the contact pin engages the terminal of an electric device such as a power transformer or the like.

Claim 1
Independent Claim
218 words
An electric elbow connector comprising a unitary contact body of conducting material having a base portion of substantial mass and a coupling portion of substantially less mass than said base portion, a threaded contact making passage formed in said base portion, a second contact making passage formed in said coupling portion and transversely disposed relative to said threaded contact making passage and in communication therewith, the thickness of the sides and upper portion which define said second contact making passage in a direction normal to the axis of said second passage being of a substantially smaller dimension than the length of the threaded portion of the contact making passage and the length of said second contact making passage axially thereof being substantially less than the length of said threaded contact making passage axially thereof, a contact sleeve having one end of somewhat smaller diameter than the diameter of said second contact making passage and disposed in said second contact making passage, and a contact pin in threaded engagement with said threaded contact making passage and having its inner end in high pressure contact with said one end of said contact sleeve such that said coupling portion is deformed without exceeding the elastic limit thereof but without causing any significant deformation of said base portion of said contact body.
Claim 2
Dependent Claim
218 words
An electric elbow connector comprising a unitary contact body of conducting material having a base portion of substantial mass and a coupling portion of substantially less mass than said base portion, a threaded contact making passage formed in said base portion, a second contact making passage formed in said coupling portion and transversely disposed relative to said threaded contact making passage and in communication therewith, the thickness of the sides and upper portion which define said second contact making passage in a direction normal to the axis of said second passage being of a substantially smaller dimension than the length of the threaded portion of the contact making passage and the length of said second contact making passage axially thereof being substantially less than the length of said threaded contact making passage axially thereof, a contact sleeve having one end of somewhat smaller diameter than the diameter of said second contact making passage and disposed in said second contact making passage, and a contact pin in threaded engagement with said threaded contact making passage and having its inner end in high pressure contact with said one end of said contact sleeve such that said coupling portion is deformed without exceeding the elastic limit thereof but without causing any significant deformation of said base portion of said contact body.
Claim 3
Dependent Claim
52 words
A connector according to claim 1 wherein the contact making end of said contact pin is of smaller diameter than the threaded adjacent portion thereof whereby high pressure contact is established between said contact making end of said contact pin and the outer surface of said shank end of said contact sleeve.
Claim 4
Dependent Claim
26 words
A connector according to claim 1 wherein the transverse dimension of said contact pin is substantially smaller than the length of said threaded contact making passage.
Claim 5
Dependent Claim
87 words
A connector according to claim 1 wherein a preformed housing formed at least in part of yieldable material and having angularly related intersecting cavity defining passages is disposed about said contact body and arranged with each cavity defining passage in coaxial relation with one of said contact making passages in said contact body and wherein the difference in diameter between said one end of said contact sleeve and said second contact making passage is approximately 0.005 inch and wherein said contact body is formed of aluminum alloy.
