Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
360 words
A connector for a flat cable having a conductor, said connector comprising: a bendable metal plate, said plate being bendable along a bending line to provide a first arm portion and a second arm portion extending from said bending line; a first radially deformable tubular member of metal extending from the surface of said first arm portion which faces said second arm portion when said plate is bent, said first tubular member being disposed with its longitudinal axis substantially perpendicular to the plane of said surface and said first tubular member having a distal end surface which is engageable with said conductor with bending of said plate and having a wall thickness such that at least said distal end thereof is radially deformable inwardly upon engagement with said conductor and bending of said plate; and a second radially deformable tubular member of metal extending from the surface of said second arm portion which faces said first arm portion when said plate is bent, said second tubular member being disposed with its longitudinal axis substantially perpendicular to the plane of said surface of said second arm portion, said second tubular member having a bore of a size which is greater than the exterior size of said first tubular member by at least 1/3 the thickness of said conductor and being disposed on said second arm portion to receive said first tubular member in said bore with the wall of said bore spaced radially from the exterior surface of said first tubular member when said plate is bent and said second tubular member having a distal end which is engageable with said conductor with bending of said plate and having a wall thickness such that at least said distal end thereof is radially deformable outwardly upon engagement with said conductor and bending of said plate; whereby by bending said plate and causing said arm portions to move toward each other, the distal ends of said first and second tubular members engage said conductor and deform inwardly and outwardly, respectively, without penetrating through said conductor and the distal end of said first tubular member enters into said bore of said second tubular member.
Claim 2
Dependent Claim
360 words
A connector for a flat cable having a conductor, said connector comprising: a bendable metal plate, said plate being bendable along a bending line to provide a first arm portion and a second arm portion extending from said bending line; a first radially deformable tubular member of metal extending from the surface of said first arm portion which faces said second arm portion when said plate is bent, said first tubular member being disposed with its longitudinal axis substantially perpendicular to the plane of said surface and said first tubular member having a distal end surface which is engageable with said conductor with bending of said plate and having a wall thickness such that at least said distal end thereof is radially deformable inwardly upon engagement with said conductor and bending of said plate; and a second radially deformable tubular member of metal extending from the surface of said second arm portion which faces said first arm portion when said plate is bent, said second tubular member being disposed with its longitudinal axis substantially perpendicular to the plane of said surface of said second arm portion, said second tubular member having a bore of a size which is greater than the exterior size of said first tubular member by at least 1/3 the thickness of said conductor and being disposed on said second arm portion to receive said first tubular member in said bore with the wall of said bore spaced radially from the exterior surface of said first tubular member when said plate is bent and said second tubular member having a distal end which is engageable with said conductor with bending of said plate and having a wall thickness such that at least said distal end thereof is radially deformable outwardly upon engagement with said conductor and bending of said plate; whereby by bending said plate and causing said arm portions to move toward each other, the distal ends of said first and second tubular members engage said conductor and deform inwardly and outwardly, respectively, without penetrating through said conductor and the distal end of said first tubular member enters into said bore of said second tubular member.
Claim 3
Dependent Claim
54 words
A connector for a flat cable as set forth in claim 1 wherein said first tubular member has a peripheral surface at its distal end which lies substantially in a single first plane and said second tubular member has a peripheral surface at its distal end which lies substantially in a single second plane.
Claim 4
Dependent Claim
31 words
A connector for a flat cable as set forth in claim 2 wherein said single first plane is substantially parallel to the plane of said surface of said first arm portion.
Claim 5
Dependent Claim
31 words
A connector for a flat cable as set forth in claim 3 wherein said single second plane is substantially parallel to the plane of said surface of said second arm portion.
Claim 6
Dependent Claim
49 words
A connector for a flat cable as set forth in claim 1 wherein the height of said first tubular member above said surface of said first arm portion is at least equal to one-half the height of said second tubular member above said surface of said second arm portion.
Claim 7
Dependent Claim
30 words
A connector for a flat cable as set forth in claim 5 wherein said height of said first tubular member is greater than said height of said second tubular member.
Claim 8
Dependent Claim
31 words
A connector for a flat cable as set forth in claim 1 wherein each of said first tubular member and said second, tubular member has the cross-section of a hollow cylinder.
Claim 9
Dependent Claim

A connector for a flat cable as set forth in claim 7 wherein the inner diameter of said second tubular member is greater than the outer diameter of said first tubular member by at least 0.1 millimeter.
Claim 10
Dependent Claim
35 words
A connector for a flat cable as set forth in claim 8 wherein the wall thicknesses of said first and second tubular members is in the range from about 0.3 millimeter to about 0.8 millimeter.
Claim 11
Dependent Claim

Claim 14
Dependent Claim
253 words
In combination, a flat cable comprising at least one flat conductor having insulation on the surfaces thereof and a connector mechanically secured and electrically connected to said cable, said connector comprising: a metal plate bent intermediate its ends to provide a first arm portion and a second arm portion and disposed with said cable between said first arm portion and said second arm portion; a first tubular member extending from said first arm portion and through said insulation into conductive contact with said conductor without passing therethrough, at least the distal end of said first, tubular member being tapered and having a reduced radius as compared to the opposite end thereof at said first arm portion and said distal end deforming said conductor with respect to portions of said conductor outside said first tubular member; a second tubular member extending from said second arm portion and through said insulation into conductive contact with said conductor without passing therethrough, at least a portion of said second tubular member encircling at least a portion of said first tubular member and at least the distal end of said second tubular member being flared outwardly as compared to the opposite end thereof at said second arm portion; and said insulation being removed from said conductor at the tapered portion of said first tubular member and at the flared portion of said second tubular member to provide conductive contact between said conductor, on the one hand, and said tapered portion and said flared portion, on the other hand.
Claim 15
