A coaxial cable female connector for inclusion in a port of a device or outer shell of a cable connector, includes a centrally located female pin within a pin carrier, the pin has an upper portion with two opposing resilient arms configured for receiving the central pin of a mating male connector. A non-electrically conductive cap is partially covered with an electrically conductive coating, and configured for seating upon said pin carrier, and for maintaining a ground or electrical connection between a shell of a male connector mated to a shell of the female connector, even if the male connector mating to the female connector loosens.

The mechanism of claim 1, wherein said electrically conductive cover and said cap are configured to provide for said outer circumferential band to be flush with the top of said cap, and at least portions of said cover upon sidewall portion of said cap being in slidable contact with opposing inner sidewalls of said shell. 3. The mechanism of claim 2, wherein said cover further includes a semicircular ring or band and protruding outward from a bottommost portion for slideably contacting the opposing associated inner sidewall of said shell. 4. The mechanism of claim 2, wherein said cover further includes a side ring of spaced apart nibs or semicircular protrusions extending outward from a bottommost portion for slidably contacting opposing associated inner sidewalls of said shell. 5. The mechanism of claim 2, wherein said cover further includes a plurality of spaced apart flexible spring fingers around its bottommost side portion for slideably contacting the opposing associated inner sidewall of said shell. 6. The mechanism of claim 1, wherein said electrically conductive cover is configured to provide for its said outer circumferential band to extend above and have a greater diameter than the top of said cap, and at least portions of said cover upon sidewall portions of said cap being in slideable contact with opposing inner sidewalls of said shell. 7. A female coaxial cable connector comprising: an electrically conductive cylindrical shell including centrally located openings in top and bottom portions, respectively, and a centrally located cavity having inner sidewalls;a female connector mechanism configured for being securely retained within the cavity of said housing, said mechanism including: an electrically non-conductive pin carrier including two spaced apart opposing resilient arms in an uppermost portion thereof, said resilient arms each having a free end, and a lowermost portion having a centrally located through hole, said arms extending from said lowermost portion toward the top of said housing, a bottom portion being proximate the bottom portion of said housing;an electrically conductive female pin including: two spaced apart opposing spring-like arms in an upper portion configured for receiving therebetween and mechanically engaging an end of a center conductor of a coaxial cable or central pin of a mating male coaxial connector to immediately provide an electrically conductive path therebetween, a circular middle portion from which said spring-like arms extend, a circular lower portion of smaller diameter than and extending from a central portion of said middle portion, a centrally located through hole extending through said middle and lower portions;said female pin being securely retained within said pin carrier, with the outwardly flared ends of said female pin being positioned above said resilient arms, the lower portion of said pin protruding away from or out of the bottom portion of said pin carrier, and a centrally located hole in the bottom of said housing; andan electrically non-conductive circular cap having a top and bottom, configured for secure installation of its bottom portion over at least top portions of both said resilient arms of said pin carrier, and said female pin, respectively, an upper portion of said cap jutting partly out of the top opening of said housing or shell, a top of said cap including a centrally located hole configured for guiding the center conductor of a coaxial cable or male pin of a mating male connector into the central portion of said female pin, an interior of said cap being hollow with interior walls configured to permit said cap to move downward to exert an inward force on the resilient arms of said pin carrier as a mating male connector is installed onto the housing or shell of said female coaxial connector, for in turn causing said resilient arms to exert an inward force on the spring-like arms of said pin, for obtaining increased mechanical and electrical connection between said male and female pins, whereas as an installed male connector is removed from said shell, said resilient arms move outward forcing said cap to move upward;a unitary electrically conductive cover secured to top and sidewall portions of said cap, said cover being configured to form an outer circumferential band on the top of said cap spaced away from the cap's centrally located holes, said cover extending around sidewall portions of said cap for maintaining electrical and mechanical contact with said shell. 8. The connector of claim 7, wherein said cover and said cap are configured to provide for said circumferential band to be flush with the top of said cap, and at least sidewall portions of said cover being in slideable contact with opposing inner sidewalls of said shell. 9. The connector of claim 8, wherein said cover further includes a semicircular ring or band protruding outward from a bottommost portion for slideably contacting the opposing associated inner sidewall of said shell. 10. The connector of claim 8, wherein said cover further includes a side ring of spaced apart nibs or semicircular protrusions extending outward from a bottommost portion for slidably contacting opposing associated inner sidewalls of said shell. 11. The connector of claim 8, wherein said cover further includes a plurality of spaced apart flexible spring fingers around its bottommost side portion for slideably contacting the opposing associated inner sidewall of said shell. 12.

The connector of claim 7, wherein said female pin further includes a through hole in the lower portion thereof for permitting sealant to be injected into and fill the interior cavities of at least lower portions thereof, for preventing moisture from migrating from the upper portion into the middle portion, and therefrom through the lower portion, into a device associated with said connector. 14. The connector of claim 13, further including the lower portion of said female pin protruding from the bottom of said pin carrier being partially surrounded by a circular cavity formed both by the opening in the bottom portion of said housing, and by the bottom of said pin carrier, the circular cavity serving to receive sealant material for filling the cavity and surrounding an associated portion of said female pin, for preventing moisture from migrating through said housing or shell and said pin carrier into an associated device to which said connector is attached. 15. The connector of claim 7, further including a resilient locking ring about the end of the lowermost portion of said pin carrier, said locking ring being dimensioned to frictionally engage interior wall portions of the cavity of said housing, for securely retaining said pin carrier in said housing. 16. The connector of claim 7, wherein the two opposing spaced apart opposing resilient arms of said pin carrier each have interior semicircular walls for receiving said female pin. 17.
