Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
A solderless connector for supporting and making electrical contact with an insulated wire, comprising: a rigid block having a short leg and a parallel extended leg defining a narrow groove therebetween, said short leg having a flat fully exposed terminal surface generally perpendicular to said extended leg, and said extended leg being bifurcate and defining a narrow wire-accepting slot; and a thin bifurcate conductive resilient contact plate fitting tightly within said groove and substantially against said extended leg and defining a deep narrow slot in line with saiD slot in said leg, for receiving and making resilient permanent spring compression reserve contact with a wire forcefully inserted into said slots and against said terminal surface.
Claim 2
Dependent Claim
115 words
A solderless connector for supporting and making electrical contact with an insulated wire, comprising: a rigid block having a short leg and a parallel extended leg defining a narrow groove therebetween, said short leg having a flat fully exposed terminal surface generally perpendicular to said extended leg, and said extended leg being bifurcate and defining a narrow wire-accepting slot; and a thin bifurcate conductive resilient contact plate fitting tightly within said groove and substantially against said extended leg and defining a deep narrow slot in line with saiD slot in said leg, for receiving and making resilient permanent spring compression reserve contact with a wire forcefully inserted into said slots and against said terminal surface.
Claim 3
Dependent Claim
13 words
Connector of claim 1 wherein said block is of rigid electrical insulation material.
Claim 4
Dependent Claim
23 words
Connector of claim 2 wherein said contact plate is extended from the bifurcate wire-contacting portion to form at least one additional contact member.
Claim 5
Dependent Claim
18 words
Connector of claim 3 wherein a said additional contact member is in the form of a contact post.
Claim 6
Dependent Claim
18 words
Connector of claim 3 wherein a said additional contact member includes at least one additional bifurcate wire-contacting portion.
Claim 7
Dependent Claim
20 words
Connector of claim 3 wherein a said additional contact member is in the form of a flat plate spring contact.
Claim 8
Dependent Claim
22 words
Connector of claim 3 wherein a said additional contact member is in the form of at least one resilient tubular contact member.
Claim 9
Dependent Claim
33 words
Connector of claim 3 wherein one said additional contact member is a second thin bifurcate contact plate and another said additional contact member is in the form of a flat plate spring contact.
Claim 10
Dependent Claim
27 words
A telephone connecting block including a flat base for attachment to a supporting structure, and integral therewith, a plurality of solderless connectors as defined in claim 6.
