Abstract

In addition to the single molded part incorporating features of the conventional nut, sealing member and body, the connector includes a post and a hollow compression sealing ring. The post includes an integrally formed stem and flange portions, with the compression ring axially movable upon the body and including a tapered surface which applies a radially inward force to the body, compressing the cable and providing tight frictional engagement of the connector and cable. When in its fully installed position, the axial length of the ring is sufficient to entirely enclose the unitary body and nut, preferably having an interference fit with the outer surface of the nut portion, thus locking and sealing the connector threads to the equipment port. The compression ring is preferably of metal to shield the internal plastic parts of the connector from UV rays.

Claims

1. The method of connecting a coaxial cable to a port of a piece of electrical equipment, said method comprising:

a) first threadedly engaging a first end of a coaxial cable connector having first and second ends, to a threaded shaft surrounding said port;

b) then inserting a terminal end of said cable, previously prepared by removing specified axial lengths of individual layers of said cable, into said second end of said connector and advancing said terminal end to a predetermined position with respect to said connector wherein said terminal end is surrounded by a body portion of said connector; and

c) then applying a radially compressive force to said body portion and to said terminal end within said body portion.

2. The method of claim 1 and further comprising forming said body portion as a unitary plastic molding which includes said first and second ends.

3. The method of claim 2 wherein said first end includes a first inner surface wherein threads are formed in the molding of said body portion and a first outer surface concentrically surrounding said threads.

4. The method of claim 3 wherein said radially compressive force is applied by moving a hollow ring having second inner and outer surfaces from a first to a second position wherein said ring surrounds said body portion including said first outer surface.

5. The method of claim 4 wherein said first outer surface is formed with a diameter greater than the portion of said second inner surface, whereby movement of said ring to said second position applies a radially compressive force to said threads.

6. The method of claim 5 wherein said ring has an axial length at least as great as the axial length of said body portion, whereby said body portion is substantially fully enclosed by said ring in said second position thereof.

7. The method of claim 6 and further comprising applying visible indicia to said cable prior to insertion thereof into said second end of said connector, said indicia indicating the proper extent of axial insertion of said terminal end into said connector.

8. The method of claim 7 wherein said ring is formed of metal.
