Abstract
Abstract An insulation stripping, solderless electrical connector formed of a twisted length of wire-like resilient material having the lower U shaped portion forming a conductor-engaging pressure junction to securely hold the conductor therein. In one of its embodiments, the connector includes exposed twisted, sharpened portions at the upper or entrance portion which cut and clean the insulation from a conductor. In another embodiment of the invention, the entrance portion or channel is provided with facing serrated edges to clean and strip the insulation from the conductor.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
101 words
An electrical circuit connector adapted to conductively engage an insulated conductor comprising: a connector member formed of generally rectangular metallic stock and having a pair of upwardly extending sidewalls forming a conductor-engaging junction at a portion thereof, said sidewalls having upper insulation removing inner facing portions biased toward each other, at least one of said inner facing portions having a plurality of sharpened edge portions formed by twisting said facing portion along a part of its length, said sharpened edge portions being adapted to remove the insulation from an insulated conductor as it is drawn between said walls toward said junction.
Claim 2
Dependent Claim
101 words
An electrical circuit connector adapted to conductively engage an insulated conductor comprising: a connector member formed of generally rectangular metallic stock and having a pair of upwardly extending sidewalls forming a conductor-engaging junction at a portion thereof, said sidewalls having upper insulation removing inner facing portions biased toward each other, at least one of said inner facing portions having a plurality of sharpened edge portions formed by twisting said facing portion along a part of its length, said sharpened edge portions being adapted to remove the insulation from an insulated conductor as it is drawn between said walls toward said junction.
Claim 3
Dependent Claim
35 words
The electrical connector described in claim 1 and further comprising an insulated housing of plastic-like material formed around said connector, said housing having slotted openings therein in substantial alignment with the openings in said connector.
Claim 4
Dependent Claim
26 words
An electrical connector as claimed in claim 1 wherein said sidewalls diverge above said sharpened edge portions to form an entrance opening for said insulated conductor.
Claim 5
Dependent Claim
34 words
An electrical connector as described in claim 3 wherein said entrance opening sidewalls form a cam-like surface at their lower portion for resiliently separating said sharpened edge portions as said conductor is slid therebetween.
Claim 6
Dependent Claim
32 words
The electrical connector as described in claim 1 and further comprising a plurality of like connectors fixed to each other by a link member extending between said sidewalls forming said entrance opening.
Claim 7
Dependent Claim
18 words
The electrical connectors described in claim 5 wherein said link member has an indentation therein to facilitate separation.
Claim 8
Dependent Claim
38 words
The electrical connector Described in claim 5 and further comprising an insulated housing of plastic-like material formed around said plurality of connectors, said housing having slotted openings therein in substantial alignment with said entrance openings in said connectors.
Claim 9
Dependent Claim
26 words
An electrical connector as described in claim 1 wherein each of said sidewalls are twisted to form a plurality of facing sharpened edges on each sidewall.
Claim 10
Dependent Claim
29 words
The electrical connector described in claim 8 wherein said connector is formed from resilient square stock coated with a layer of relative inert material having good electrical conductive properties.
Claim 11
Dependent Claim
35 words
An electrical connector as set forth in claim 1 wherein said sidewalls converge toward each other from said conductor-engaging portion and form, at their point of convergence, a restricted opening into said conductor-engaging junction portion.
Claim 12
Dependent Claim
36 words
An electrical connector as set forth in claim 10 wherein said point of convergence of said sidewalls operates to clean the insulation from said conductor member as it is drawn therebetween into said conductor-engaging junction portion.
Claim 13
Dependent Claim
162 words
An electrical circuit connector adapted to cut the insulation from and conductively engage an insulated conductor comprising: a conductive connector member formed of resilient generally rectangular metallic stock having a pair of upwardly extending sidewalls forming an integral, generally U-shaped conductor-engaging junction at a lower portion thereof, said sidewalls extending upwardly from said junction forming a conductor-receiving channel therebetween, said sidewalls diverging to form an entrance opening into said channel, said conductor receiving channel having insulation-removing inner facing portions biased toward each other, said inner facing portions being formed by twisting said sidewalls such that corner edges thereof face each other, at least one of said edges having a plurality of, serrated sharpened portions along a part of its length to remove the insulation from an insulated conductor as it is drawn between said sidewalls toward said junction and said upstanding sidewalls converging toward each other below said serrated inner facing portions forming a restricted entrance opening into said conductor-engaging junction portion.
Claim 14
Dependent Claim
162 words
An electrical circuit connector adapted to cut the insulation from and conductively engage an insulated conductor comprising: a conductive connector member formed of resilient generally rectangular metallic stock having a pair of upwardly extending sidewalls forming an integral, generally U-shaped conductor-engaging junction at a lower portion thereof, said sidewalls extending upwardly from said junction forming a conductor-receiving channel therebetween, said sidewalls diverging to form an entrance opening into said channel, said conductor receiving channel having insulation-removing inner facing portions biased toward each other, said inner facing portions being formed by twisting said sidewalls such that corner edges thereof face each other, at least one of said edges having a plurality of, serrated sharpened portions along a part of its length to remove the insulation from an insulated conductor as it is drawn between said sidewalls toward said junction and said upstanding sidewalls converging toward each other below said serrated inner facing portions forming a restricted entrance opening into said conductor-engaging junction portion.
Claim 15
Dependent Claim
30 words
An electrical connector as set forth in claim 12 wherein said sidewalls form, at their point of convergence, means to prevent said biased inner facing portions from contacting each other.
Claim 16
Dependent Claim
36 words
An electrical connector as set forth in claim 13 wherein said point of convergence of said sidewalls operates to clean the insulation from said conductor member as it is drawn therebetween into said conductor-engaging junction portion.
Claim 17
Dependent Claim
28 words
The electrical connector described in claim 14 wherein said connector is formed from resilient stock coated with a layer of relative inert material having good electrical conductive properties.
