Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
70 words
A spring compression reserve wire-connector contact, comprising a pair of spaced planar interconnected resilient contact elements having multiple wire-receiving slots defined by parallel extended legs, each slot in one element being aligned with a slot in the other element, and the portion interconnecting the contact elements being relieved at both ends, each relief extending inward from the end to alignment with the outer edge of the first wire receiving slot.
Claim 2
Dependent Claim
70 words
A spring compression reserve wire-connector contact, comprising a pair of spaced planar interconnected resilient contact elements having multiple wire-receiving slots defined by parallel extended legs, each slot in one element being aligned with a slot in the other element, and the portion interconnecting the contact elements being relieved at both ends, each relief extending inward from the end to alignment with the outer edge of the first wire receiving slot.
Claim 3
Dependent Claim
20 words
The wire-connector contact of claim 1 wherein each contact element is formed with four legs defining three wire receiving slots.
Claim 4
Dependent Claim
27 words
The wire-connector contact of claim 2 wherein the two internal legs of each contact element are internally perforated to provide stress relief along the wire-contacting edges thereof.
Claim 5
Dependent Claim
15 words
The wire-connector contact of claim 3 wherein each wire receiving slot is 0.046 inch wide.
Claim 6
Dependent Claim
57 words
The wire-connector contact of claim 1 wherein the portion interconnecting the contact elements is relieved at both ends in smooth arcs and wherein the end portions of the contact elements adjacent the interconnecting portion are formed with smoothly arcuate curves reverse that of the adjacent relief, which reverse curves are blended into the curvature of the relief.
Claim 7
Dependent Claim
30 words
The wire-connector contact of claim 1 wherein each leg internal of the two end legs of each contact element is perforated to provide stress relief along the wire-contacting edges thereof.
