Method for connecting a coaxial cable
A connector for coaxial cable, and a tool and method for connecting coaxial cable. The connector may have a projection configured to extend into a channel defined by an inner conductor of the coaxial cable and to engage an inner surface of the inner conductor; and a lip configured to engage an outer surface of the inner conductor when the projection extends into the channel. The lip and the projection configured to limit the movement of the inner conductor relative to the outer conductor. The tool and method may be used to displace insulation adjacent the lead end of the inner conductor or outer conductor to facilitate connection of the connector.
1. A method for connecting a connector to an exposed end of a coaxial cable having an outer conductor, an inner conductor, and insulation disposed about the inner conductor, the outer conductor having a lead end and the inner conductor defining a channel and having a lead end, the method comprising:
displacing a portion of the insulation adjacent the lead end of one of the inner conductor and the outer conductor with a tool comprising a support and a projection and at least one protrusion extending from the support, the projection having a longitudinal axis and the protrusion being arcuate about the longitudinal axis and having an arc length of less than 90 degrees, by inserting the projection into the channel so that the protrusion contacts a surface adjacent said lead end of one of the inner conductor and outer conductor and displaces the portion of the insulation; and
removing the support, projection and protrusion from the exposed end of the coaxial cable.
2. The method of claim 1 wherein the displacing of the portion of the insulation includes rotating the tool after the projection has been inserted into the channel.
3. The method of claim 1 wherein the protrusion includes a wedge surface for displacing the portion of the insulation.
4. The method of claim 1 wherein there are two protrusions for displacing the portion of the insulation.
5. The method of claim 1 further including causing relative rotation between the tool and the coaxial cable during the displacing of the portion of the insulation.
6. The method of claim 5 wherein the tool includes a reforming member, and further including reforming the lead end of the outer conductor during the relative rotation between the tool and the coaxial cable with the reforming member.
7. The method of claim 6 wherein the reforming member and the protrusion define a gap receiving the lead end of the outer conductor during the relative rotation between the tool and the coaxial cable.
8. A method for connecting a connector to an exposed end of a coaxial cable having an outer conductor, an inner conductor, and insulation disposed about the inner conductor, the outer conductor having a lead end and the inner conductor defining a channel and having a lead end, the method comprising:
displacing a portion of the insulation adjacent the lead end of one of the inner conductor and the outer conductor with a tool comprising a support and a projection and at least one protrusion extending from the support by inserting the projection into the channel so that the protrusion contacts a surface adjacent said lead end of one of the inner conductor and outer conductor and displaces the portion of the insulation, and
positioning on the exposed end of the coaxial cable a connector having a projection and a substantially annular lip so that the projection is received by the channel and the substantially annular lip of the connector engages the outside of the lead end of the inner conductor.
9. The method of claim 8 wherein the projection includes a radially resilient portion which engages the inside of the lead end of the inner conductor during the positioning of the coaxial cable.
