Abstract

An end connector for connecting a coaxial cable to a port having a tubular body with front and rear end portions, a cable attachment section associated with the rear end portion for attaching the connector to the cable, and a port attachment section associated with the front end portion for attaching the connector to the port. The port attachment means includes a split ferrule defining a plurality of partially cylindrical resilient fingers, the fingers having inward arcuate projections defining a circumferential ridge adapted to engage the port. The split ferrule defines an inner surface which is inwardly tapered to enhance port to connector contact. A locking sheath is disposed about the front end portion of the tubular body and is adapted to engage an outer surface of the split ferrule so as to restrict the resiliency of the resilient fingers. The attachment section includes an interiorly threaded portion of the tubular body which is preceded by a non-threaded interior portion of the tubular body that is adjacent a rear end opening at the rear end portion of the tubular body.

Claims

1. An end connector for connecting a coaxial cable to a port, comprising:

a tubular body having front and rear end portions;

cable attachment means associated with said rear end portion for attaching said connector to said cable; and

port attachment means associated with said font end portion for attaching said connector to said port, said port attachment means comprising a split ferrule having an open end and a partially enclosed end, said split ferrule having a plurality of longitudinal slits extending from said open end to an intermediate region to thereby define a plurality of resilient fingers, said split ferrule defining an inner surface which is inwardly tapered from a first portion proximate to said intermediate region to a second portion proximate to said partially enclosed end of said split ferrule, wherein said inwardly tapered surface is configured to contact the front end portion of said port so as to prevent signal loss between said port and said end connector.

2. The end connector of claim 1, wherein said fingers include inward arcuate projections defining a circumferential ridge adapted to engage said port.

3. The end connector of claim 1, further comprising a sheath disposed about said front end portion of said tubular body, said sheath adapted to engage an outer surface of said split ferrule so as to restrict the resiliency of said resilient fingers.

4. The end connector of claim 1, wherein said cable attachment means comprises an interiorly threaded portion of said tubular body which is preceded by a non-threaded interior portion of said tubular body that is adjacent a rear end opening at said rear end portion of said tubular body.

5. An end connector for connecting a coaxial cable to a port, comprising:

a tubular body having front and rear end portions;

cable attachment means associated with said rear end portion for attaching said connector to said cable;

port attachment means associated with said front end portion for attaching said connector to said port, said port attachment means comprising a split ferrule defining a plurality of resilient fingers; and

a sheath disposed about said front end portion of said tubular body, said sheath being threadingly engaged with an outer surface of said split ferrule so as to be axially displaced along said ferrule between an unlocked position and a locked position in which said sheath contacts said fingers, wherein said sheath is adapted to restrict the resiliency of said resilient fingers when engaged in said locked position.

6. The end connector of claim 5, wherein said fingers include inward arcuate projections defining a circumferential ridge adapted to engage said port.

7. The end connector of claim 5, wherein said port attachment means comprises a split ferrule, said split ferrule including an open end and a partially enclosed end, and having a plurality of longitudinal slits from said open end to an intermediate region to thereby define said plurality of resilient fingers, said split ferrule defining a inner surface which is inwardly tapered from a first portion proximate to said intermediate region to a second portion proximate to said partially enclosed end of said split ferrule.

8. The end connector of claim 5, wherein said cable attachment means comprises an interiorly threaded portion of said tubular body which is preceded by a non-threaded interior portion of said tubular body that is adjacent a rear end opening at said rear end portion of said tubular body.

9. An end connector for connecting a coaxial cable to a port, comprising:

a tubular body having a front end portion and a rear end portion with a rear end opening;

port attachment means associated with said front end portion for attaching said connector to said port; and

cable attachment means associated with said rear end portion for attaching said connector to said cable, said cable attachment means comprising an interiorly threaded portion of said tubular body which is preceded by both a non-threaded interior tubular chamber portion of said tubular body and a tapered portion that is adjacent said rear end opening.

10. The end connector of claim 9, wherein said port attachment means comprises a split ferrule, said split ferrule including an open end and a partially enclosed end, and having a plurality of longitudinal slits from said open end to an intermediate region to thereby define said plurality of resilient fingers, said split ferrule defining an inner surface which is inwardly tapered from a first portion proximate to said intermediate region to a second portion proximate to said partially enclosed end of said split ferrule.

11. The end connector of claim 10, wherein said fingers include inward arcuate projections defining a circumferential ridge adapted to engage said port.

12. The end connector of claim 10, further comprising a sheath disposed about said front end portion of said tubular body, said sheath adapted to engage an outer surface of said split ferrule so as to restrict the resiliency of said resilient fingers.

13. The end connector of claim 12, wherein said fingers include outward arcuate projections defining a circumferential ridge adapted to engage said sheath in said locked position.
