Abstract
A ground rod clamp for clamping a ground rod and at least one ground wire employs a clamp body and a bolt. A transverse orifice in a first portion of the clamp body receives the ground rod and ground wire. A threaded portion of the bolt is received by a threaded axial bore in a second portion of the clamp body. The distal end of the bolt engages the ground rod and ground wires. Torquing the bolt head clamps the ground rod and ground wires within the clamp body.
Claims19
A ground rod clamp comprising:
- a clamp body having first and second portions, said first portion defining an axially elongated transverse opening, said opening having contiguous first, second and third sections, said first section having a radius R1, said second section having a radius R2, said third section having a radius R3, and wherein R1>R2>R3, said second portion defining a threaded axial bore;
- and
- bolt means having head means and shank means, said shank means having a threaded segment, said threaded segment being threadably mounted in said axial bore, said shank means being threadably displaceable into said opening.
A ground rod clamp assembly comprising:
- ground rod means;
- ground wire means comprising at least one ground wire;
- a clamp body having first and second portions, said first portion defining an axially elongated transverse opening for receiving said ground rod means and said ground wire means, said opening having contiguous first, second and third sections, said first section having a radius R1, said second section having a radius R2, said third section having a radius R3, and wherein R1>R2>R3, said second portion defining a threaded axial bore;
- and
- bolt means having head means and shank means, said shank means having a threaded segment, said threaded segment being threadably mounted in said axial bore, said shank means being threadably displaceable into said opening whereby said bolt means clamps said ground rod means and said ground wire means.

A ground rod clamp comprising:
- a clamp body having first and second portions, said first portion defining an axially elongated transverse opening, said opening having first, second and third sections, said first section having a radius R1, said second section having a radius R2, said third section having a radius R3, and wherein R1>R2>R3, said second portion defining a threaded axial bore and a partial transverse bore, said transverse bore being substantially tangential to said axial bore, said clamp body further comprising pin means disposed in said transverse bore, said pin means being comprised of polymeric material;
- and
- bolt means having head means and shank means, said shank means having a threaded segment, said threaded segment being threadably mounted in said axial bore, said threaded segment engaging said pin means whereby said pin means resists movement of said bolt means, said shank means being threadably displaceable into said opening.
