Abstract
Abstract An electrical connector for connecting insulating wire to a round post consists of two parts, an outer powdered metal sleeve and a split insert. The insert is blanked with teeth or serrations along one edge, and is formed to the inside diameter of the outer sleeve. An insulated wire is inserted into the connector in the area provided by the split in the insert, and the connector and wire are placed over the round post and the connector is circumferentially compressed. Compression of the connector forces the serrated edge of the insert against the wire, piercing the insulation and securing the wire and the connector to the post. Electrical contact from the wire to the post is made through the insert.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
115 words
A connector for electrically and mechanically connecting an insulated conductor to a round post comprising: a crimpable body having an aperture extending therethrough for receiving a round post and an insulated wire; and an insert disposed in the aperture of said crimpable body, said insert being a split inner sleeve having an outer diameter less than the inner diameter of said crimpable body, and an inner diameter greater than the diameter of said round post, said sleeve being split for receiving the insulated wire between the split edges thereof, with said insert including at least one sharp edge along a split edge thereof for penetrating an insulated conductor upon compressive deformation of said crimpable body.
Claim 2
Dependent Claim
115 words
A connector for electrically and mechanically connecting an insulated conductor to a round post comprising: a crimpable body having an aperture extending therethrough for receiving a round post and an insulated wire; and an insert disposed in the aperture of said crimpable body, said insert being a split inner sleeve having an outer diameter less than the inner diameter of said crimpable body, and an inner diameter greater than the diameter of said round post, said sleeve being split for receiving the insulated wire between the split edges thereof, with said insert including at least one sharp edge along a split edge thereof for penetrating an insulated conductor upon compressive deformation of said crimpable body.
Claim 3
Dependent Claim
18 words
A connector as set forth in claim 1, wherein said insert is fixedly mounted within the crimpable body.
Claim 4
Dependent Claim
46 words
An electRical connector as set forth in claim 1, wherein the crimpable body is cylindrical in configuration, and wherein the insert has a serrated edge surface to provide a plurality of elongated sharp edges for penetrating the insulated conductor upon compressive deformation of said crimpable body.
Claim 5
Dependent Claim
87 words
An electrical connector for connecting an insulated conductor to a round post comprising: an annular outer sleeve; an arcuate inner sleeve disposed in the annular outer sleeve and of sufficient diameter for receiving the round post, said inner sleeve having a slit extending along the longitudinal axis thereof for receiving the insulated wire, with one edge of the inner sleeve along said slit being serrated to define a plurality of sharp edges for penetrating the conductor upon the electrical connector being compressively deformed about the round post.
Claim 6
Dependent Claim
87 words
An electrical connector for connecting an insulated conductor to a round post comprising: an annular outer sleeve; an arcuate inner sleeve disposed in the annular outer sleeve and of sufficient diameter for receiving the round post, said inner sleeve having a slit extending along the longitudinal axis thereof for receiving the insulated wire, with one edge of the inner sleeve along said slit being serrated to define a plurality of sharp edges for penetrating the conductor upon the electrical connector being compressively deformed about the round post.
Claim 7
Dependent Claim
20 words
An electrical connector as set forth in claim 4 wherein the annular outer sleeve is made of a plastic material.
Claim 8
Dependent Claim
20 words
An electrical connector as set forth in claim 4 wherein the annular outer sleeve is made of sintered powdered metal.
Claim 9
Dependent Claim
74 words
A connection electrically and mechanically connecting an insulated conductor to a round post comprising: an annular outer sleeve; an annular split inner sleeve disposed in said outer sleeve, said split inner sleeve receiving the round post in its inner cylindrical surface and receiving the insulated wire between the split edges thereof, said outer sleeve and inner sleeve being compressibly deformed with the edges of the split sleeve piercing the insulation of the insulated conductor.
Claim 10
Dependent Claim
74 words
A connection electrically and mechanically connecting an insulated conductor to a round post comprising: an annular outer sleeve; an annular split inner sleeve disposed in said outer sleeve, said split inner sleeve receiving the round post in its inner cylindrical surface and receiving the insulated wire between the split edges thereof, said outer sleeve and inner sleeve being compressibly deformed with the edges of the split sleeve piercing the insulation of the insulated conductor.
Claim 11
Dependent Claim
21 words
A connection as set forth in claim 7 wherein said split inner sleeve is fixedly mounted within said annular outer sleeve.
Claim 12
Dependent Claim
34 words
A connection as set forth in claim 7 wherein said split inner sleeve includes a serrated edge surface extending along the longitudinal axis thereof providing a plurality of sharp edges penetrating the insulated conductor.
Claim 13
Dependent Claim
19 words
A connection as set forth in claim 7 wherein said annular outer sleeve is made of a plastic material.
Claim 14
Dependent Claim
20 words
A connection as set forth in claim 7 wherein said annular outer sleeve is made of a sintered powdered metal.
Claim 15
Dependent Claim
25 words
A connection as set forth in claim 7 wherein both the annular outer sleeve and the split inner sleeve are made of sintered powdered metal.
Claim 16
Dependent Claim
37 words
A connection as set forth in claim 7 wherein said split inner sleeve includes a serrated edge surface extending along the radial axis thereof providing a plurality of sharp edges piercing the insulation of the insulated conductor.
Claim 17
Dependent Claim
45 words
A connection as set forth in claim 7 wherein the outer diameter of the split inner sleeve is less than the inner diameter of the annular outer sleeve, and the inner diameter of the split sleeve is greater than the diameter of the round post.
