Abstract
Abstract This invention relates to electrical connectors, and in one embodiment comprises a "split bolt" type connector having a pressure pad member interposed between the bolt head and the nut, the conductor contacting surfaces of which are characterized by being V-shaped with alternating lands and grooves oriented substantially transverse to the axis of conductors residing therein; the land on one side of each receptacle surface being interlaced with lands on the other side of the receptacle surface.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
105 words
In apparatus for effecting clamping retention of elongated objects, at least one object contacting surface characterized by the fact that said surface is in the form of an elongated concavity having more than one set of lands with grooves therebetween, said lands and said grooves being oriented substantially transverse to the longitudinal axis of said concavity, along which elongated objects are oriented when clampingly retained therein, the ends of the lands of one of said sets being aligned with the ends of the grooves in the other of said sets and in proximity to the ends of the lands in said other of said sets.
Claim 2
Dependent Claim
105 words
In apparatus for effecting clamping retention of elongated objects, at least one object contacting surface characterized by the fact that said surface is in the form of an elongated concavity having more than one set of lands with grooves therebetween, said lands and said grooves being oriented substantially transverse to the longitudinal axis of said concavity, along which elongated objects are oriented when clampingly retained therein, the ends of the lands of one of said sets being aligned with the ends of the grooves in the other of said sets and in proximity to the ends of the lands in said other of said sets.
Claim 3
Dependent Claim
24 words
The surface described in claim 1 wherein the lands of said sets at their facing ends form an angle of less than 180 degrees.
Claim 4
Dependent Claim
34 words
The surface described in claim 2 wherein the tops of the lands of each of said sets describe a plane in the region of juxtaposition with the lands of the other of said sets.
Claim 5
Dependent Claim
12 words
The surface described in claim 3 wherein the planes are substantially flat.
Claim 6
Dependent Claim
16 words
The surface described in claim 3 or claim 4 wherein said angle is approximately 120 degrees.
Claim 7
Dependent Claim
139 words
A cable clamp comprising a split-bolt, a pressure pad member, and a nut with an associated nut rider wherein at least one among the surfaces comprising the end of this slot in said bolt next to the bolt head, the surface of said nut-rider facing said pad member, and the top and bottom of said pad member, is in the form of an elongated concavity having more than one set of lands with grooves therebetween, said lands and said grooves being oriented substantially transverse to the longitudinal axis of said concavity along which cables are oriented when clampingly retained therein, the ends of the lands of one of said set being aligned with the ends of the grooves of the other of said sets and in proximity to the ends of the lands in the other of said sets.
Claim 8
Dependent Claim
139 words
A cable clamp comprising a split-bolt, a pressure pad member, and a nut with an associated nut rider wherein at least one among the surfaces comprising the end of this slot in said bolt next to the bolt head, the surface of said nut-rider facing said pad member, and the top and bottom of said pad member, is in the form of an elongated concavity having more than one set of lands with grooves therebetween, said lands and said grooves being oriented substantially transverse to the longitudinal axis of said concavity along which cables are oriented when clampingly retained therein, the ends of the lands of one of said set being aligned with the ends of the grooves of the other of said sets and in proximity to the ends of the lands in the other of said sets.
Claim 9
Dependent Claim
24 words
The clamp described in claim 6 wherein the lands of said sets at their facing ends form an angle of less than 180 degrees.
Claim 10
Dependent Claim
34 words
The clamp described in claim 7 wherein the tops of the lands of each of said sets describe a plane in the region of juxtaposition with the lands of the other of said sets.
