Abstract

A tool for everting a stripped portion of the braided conductive shielding of a coaxial cable in preparation for the attachment of a coaxial cable connector thereto. In order to attach a coaxial cable connector to the end of a coaxial cable, a portion of the cable jacket near the end of the coaxial cable is first stripped by a suitable stripping tool to expose a portion of the underlying braided shielding. The tool of the present invention is employed to evert the exposed portion of the braided shielding layer and fold it over the unstripped adjacent jacket. A preferred embodiment of the tool includes a handle with a circular opening therein dimensioned to receive a coaxial cable inserted thereinto. The circular opening has a plurality of bristles disposed around the circumference thereof. A fixed end of the bristles is supported by the handle. The free opposing end of the bristles extend radially inwardly toward the center of the circular opening. When the stripped end of the coaxial cable is inserted into the circular opening in a direction orthogonal to the bristles, the plurality of bristles engage the cut ends of the conductive filaments of the braided shielding and comb the filaments rearwardly to overlie the unstripped portion of jacket adjacent thereto. The cable is then removed from the circular opening by lateral motion through a slot in the circular opening.

Claims

1. A tool for flaring and everting an exposed portion of a braided shielding on a stripped end of a coaxial cable in preparation for the attachment of a coaxial cable connector thereto, the coaxial cable comprising a outer jacket, the tool comprising:

(a) a handle portion adapted to be grasped by the hand; and

(b) a working portion integral with said handle portion, said working portion comprising an aperture having a circumference; and

(c) a plurality of elastically deformable bristles, each bristle comprising said plurality of bristles having a fixed end affixed to said circumference of said aperture and a free end extending into said aperture, said free ends of said plurality of bristles collectively defining a fuzzy aperture; and

(d) a slot extending outwardly from said circumference of said aperture.

3. A method for everting the exposed portion of braided shielding on a stripped end of a coaxial cable comprising the steps of:

(a) presenting a coaxial cable having an outer jacket and a layer of braided shielding underlying said outer jacket wherein a portion of said outer jacket on an end of the coaxial cable is stripped to expose a portion of said braided shielding;

then

(b) presenting a tool in accordance with claim 1 or claim 2;

then

(c) thrusting said stripped end of said cable between said free ends of said plurality of bristles.

2. A tool for flaring and everting an exposed portion of a braided shielding on a stripped end of a coaxial cable in preparation for the attachment of a coaxial cable connector thereto, the coaxial cable comprising a outer jacket, the tool comprising:

(a) a handle portion adapted to be grasped by the hand; and

(b) a working portion integral with said handle portion, said working portion comprising a pair of parallel opposing jaws having a slot therebetween; and

(c) a plurality of elastically deformable bristles disposed within said slot, each bristle comprising said plurality of bristles having a fixed end attached to one of said pair of jaws and a free end extending into said slot, said free ends of said plurality of bristles collectively defining a fuzzy slit within said slot.
