Abstract
A staking nut and a grounding clamp with the staking nut are disclosed in which the clamp includes a flexible metal strap with openings through the ends of the strap. Threaded studs extend through the openings at one end of the strap to firmly attach the lug of a grounding conductor to the strap. The staking nuts are provided through the openings at the other end of the strap to prevent removal of the nuts from the strap, but permit rotation so that the nuts while held captive to the strap may be threaded upon the threaded studs to clamp the grounding clamp to a coaxial cable which is to be grounded.
Claims15
A staking nut comprising
- a block portion having a face, and at least one surface capable of being engaged by a tool to rotate the block portion;
- a passage extending into said block portion from said face, said passage being threaded to receive a threaded stud therein;
- a substantially cylindrical staking shaft on said block portion and extending from said face, said staking shaft having a given external cross-sectional dimension;
- said staking shaft being formed of a material which is capable of expansion to an external cross-sectional dimension which is greater than said given external cross-sectional dimension;
- and
- said staking shaft also including a passage which is coaxial with the passage of said block portion, said staking shaft passage having a minimum cross-sectional dimension prior to expansion which is at least as large as the maximum cross-sectional dimension of the passage in the block portion.
A grounding clamp comprising:
- a flexible elongate metal strap having first and second ends;
- an elongate threaded stud at said first end of said strap;
- a nut at said second end of said strap, said nut having a threaded passage therein aligned to threadedly receive said threaded stud into said threaded passage of said nut to attach said first and second ends together;
- and
- a coupling which couples said nut to said second end to prevent removal of said nut from said second end, but permit rotation of said nut relative to said stud while said nut is coupled to said second end to thread said nut onto said threaded stud.
