## Abstract

An anti-torque coaxial cable connection apparatus comprising a cylindrical nut driver having a cut away portion alignable with a slot in a coaxial cylindrical wrench having a portion shaped to engage a cable adaptor having a cable adaptor portion adapted to be firmly engaged by said wrench. The alignment of the nut driver cutaway and the wrench slot forms an aperture which can be aligned over a cable inelastically joined to a cable adaptor to allow tightening in situ of a cable connector comprising a cable adaptor and a nut without interfering with said cable while the cable adaptor is firmly held to prevent damage to said inelastic joint.

## Claims

### Claim 1

A method of tightening a cable connector which is inelastically coupled to a cable, the connector being adapted to couple the cable to a mating device, said method comprising the steps of:
providing the cable connector having at least a cable adaptor and a nut, said cable adaptor being adapted to be firmly engaged by a tool, said tool having an adaptor engagement portion with a slot said adaptor engagement portion being adapted to firmly engage said cable adaptor without interferring with said cable;
furnishing a nut driver having a nut engagement portion rotatably disposed around said adaptor engagement portion of said tool and having a cutaway cylindrical portion capable of being aligned with said slot in said tool;
engaging said nut with said nut engagement portion;
passing said cable through said slot in said adaptor engagement portion, and through said cutaway cylindrical portion;
restraining said cable adaptor from rotation about said cable with said tool; and
rotating said nut driver and thereby rotating said nut to tighten said cable connector to the mating device.

### Claim 2

An apparatus for tightening a cable connector to a mating device, said cable connector having at least a cable adaptor and a nut, said cable adaptor being inelastically coupled to said cable, said cable adaptor being adapted to be firmly engaged by a tool, said apparatus comprising in combination:
a tool having a portion adapted for firmly engaging and for preventing rotation of the cable adaptor, said tool having a cylindrical portion with a slot for allowing clearance for the cable; and
a nut driver rotatably disposable around said tool for firmly tigtening the nut, said nut driver having an engagement portion shaped to allow said nut driver to firmly engage and to turn the nut, said engagement portion being capable of coaxial rotation around said portion of said tool, said nut driver having a cut away cylinrical portion coaxially arranged around and capable of being aligned with said slot in said cylindrical portion of said tool to form an aperture larger than the cable, said aperture allowing said nut driver to be axially fed and rotated around said tool while providing clearance for the cable.
