Abstract

A gripping member for a coaxial cable connector is disclosed. The gripping member has a front end and a rear end opposite the front end, and an outer surface and an inner surface defining a longitudinal hole extending between the front end and the rear end. A first portion of the gripping member terminates at the front end. A second portion of the gripping member terminates at the rear end and includes at least one notch which extends from the inner surface of second portion to a certain depth from inner surface. The gripping member is configured to be forced under a body of a coaxial cable connector when driven axially forward by a shell of a coaxial cable connector to secure a coaxial cable to the connector.

Claims

1. A gripping member for a coaxial cable connector, the gripping member comprising:

a front end and a rear end opposite the front end;

an outer surface and an inner surface defining a longitudinal hole extending between the front end and the rear end;

a first portion which terminates at the front end; and

a second portion which terminates at the rear end and comprising at least one notch which extends from the inner surface of second portion to a certain depth from inner surface,

wherein the gripping member is configured to secure a coaxial cable to a coaxial cable connector, wherein the coaxial connector has a body, a shell coupled to the body and a gripping member with a notch to a certain depth from an inner surface disposed on an inner surface of the shell.

2. The gripping member of claim 1, wherein the gripping member is configured to be displaced radially inwardly when the gripping member is forced under the body of a coaxial cable connector.

3. The gripping member of claim 1, wherein the front end of the gripping member is configured to be displaced radially inwardly when the gripping member is forced under the body of a coaxial cable connector.

4. The gripping member of claim 1, wherein the rear end of the gripping member is configured to be displaced radially inwardly when the gripping member is forced under the body of a coaxial cable connector.

5. The gripping member of claim 1, wherein the first portion comprises at least one slot cut through the first portion from the inner surface through the outer surface and extending a certain length from the front end into first portion.

6. The gripping member of claim 5, wherein the first portion comprises a plurality of slots.

7. The gripping member of claim 6, wherein the plurality of slots define sections there between.

8. The gripping member of claim 7, wherein the slots and the sections are configured to facilitate an inward radial displacement of the first portion when the gripping member is driven axially forward.

9. A connector for coupling an end of a coaxial cable to a terminal, the coaxial cable comprising an inner conductor, a dielectric surrounding the inner conductor, an outer conductor surrounding the dielectric, a braided shield surrounding the dielectric, and a jacket surrounding the braided shield, the connector comprising:

a body comprising a rear end, a front end, and an internal surface extending between the rear and front ends of the body, the internal surface defining a longitudinal hole;

a shell comprising a rear end, a front end surrounding at least a portion of the body, and an inner surface defining a longitudinal hole extending between the rear and front ends of the shell, the shell being axially movable over an outside portion the body between a rearward position and a forward position;

a post disposed at least partially within the longitudinal hole of the body, the post having a rear end, an inner surface and an outer surface, and wherein the outer surface of the post and the internal surface of the post define an annular cavity therebetween; and

a gripping member disposed within the longitudinal hole of the shell between the front and rear ends thereof, the gripping member comprising a front end, a rear end, an outer surface, an inner surface defining an opening therein, a first portion adjacent the front end, and a second portion adjacent the rear end, wherein the second portion comprises at least one notch which extends from the inner surface of second portion to a certain depth from inner surface,

wherein the gripping member is configured to secure a coaxial cable to a coaxial cable connector.

10. The connector of claim 9, wherein the gripping member secures the coaxial cable to the coaxial cable connector when at least part of the gripping member is forced under the body when driven axially forward by the shell.

11. The connector of claim 9, wherein the first portion comprises a plurality of slots cut through the first portion from the inner surface through the outer surface and extending a certain length from the front end into first portion, and wherein the plurality of slots define sections there between.

12. The connector of claim 9, wherein the slots and the sections are configured to facilitate an inward radial displacement of the first portion when the gripping member is driven axially forward.

13. The connector of claim 9, wherein, in the forward position, the inner surface of the deformable gripping ring, from the rear end to the front end thereof, contacts the jacket of the cable.

14. The connector of claim 13, wherein a portion of the jacket flows into one or more of the notches in the forward position.
