Independent Claim
61 words
A contact member for a solderless connector, comprising a thin resilient flat plate having at least one pair of parallel extended legs defining an open-ended wire-receiving slot, at lest one of said legs having a perforation laterally spaced from the wire-receiving slot for partial relief of stress at the wirecontacting edge during forceful insertion of a wire into said wire-receiving slot.
Claim 2
Dependent Claim
61 words
A contact member for a solderless connector, comprising a thin resilient flat plate having at least one pair of parallel extended legs defining an open-ended wire-receiving slot, at lest one of said legs having a perforation laterally spaced from the wire-receiving slot for partial relief of stress at the wirecontacting edge during forceful insertion of a wire into said wire-receiving slot.
Claim 3
Dependent Claim
24 words
The contact member of claim 1 having three extended legs defining two wire-receiving slots and wherein the central leg is perforated for stress relief.
Claim 4
Dependent Claim
16 words
The contact member of claim 1 wherein each of said legs is perforated for stress relief.
Claim 5
Dependent Claim
25 words
The contact member of claim 1 wherein said legs extend a distance sufficient to permit insertion of at least two wires into said wire-receiving slot.
Claim 6
Dependent Claim
