Abstract

A handgrip device for a coaxial cable includes a first longitudinal section having an inner wall defining a first channel extending therethrough for receiving a connector of a coaxial cable. The first channel has generally a first diameter. A second longitudinal section is generally adjacent to the first longitudinal section for receiving a coaxial cable. The second longitudinal section has an inner wall defining a second channel extending therethrough and communicates with the first channel. The second channel has generally a second diameter which is greater than the first diameter of the first channel such that a space is maintained between the inner wall of the second channel and a coaxial cable when disposed in the second channel, whereby the space protects the coaxial cable adjacent to the connector from damage when fastening or unfastening the connector.

Claims

1. A handgrip device for a coaxial cable, comprising:

a first longitudinal section having an inner wall defining a first channel extending therethrough for receiving a connector of a coaxial cable, the first channel having generally a first diameter, and the inner wall being configured for abutting against a connector of a coaxial cable; and

a second longitudinal section generally adjacent to the first longitudinal section for receiving a coaxial cable, the second longitudinal section having an inner wall defining a second channel extending therethrough and communicating with the first channel, the second channel having generally a second diameter which is greater than the first diameter of the first channel such that a space is maintained between the inner wall of the second channel and a coaxial cable when disposed in the second channel whereby the space protects the coaxial cable adjacent to the connector from damage when fastening or unfastening the connector.

2. A handgrip device for a coaxial cable as defined in claim 1, wherein the first longitudinal section defines at least one hole extending from an outer surface to the inner wall for receiving a fastener therethrough for coupling the handgrip device to a connector of a coaxial cable.

3. A handgrip device for a coaxial cable as defined in claim 1, wherein the first longitudinal section defines two holes disposed generally at opposite sides of the first longitudinal section relative to each other, and each of the two holes extends from an outer surface to the inner wall for receiving a fastener therethrough for coupling the handgrip device to a connector of a coaxial cable.

4. A handgrip device as defined in claim 2, wherein the fastener is a set screw.

5. A handgrip device as defined in claim 1, wherein at least one radial portion of the inner wall of the first longitudinal section is shaped for engaging a similarly shaped portion of a connector of a coaxial cable to prevent the coaxial cable from rotating relative to the handgrip device.

6. A handgrip device as defined in claim 1, wherein at least one radial portion of the inner wall of the first longitudinal section is generally flat to engage a similarly shaped radial portion of a connector of a coaxial cable in order to prevent the coaxial cable from rotating relative to the handgrip device.

7. A handgrip device as defined in claim 1, wherein two radial portions disposed generally at opposite sides of the inner wall of the first longitudinal section are each shaped to engage a similarly shaped radial portion of a connector of a coaxial cable in order to prevent the coaxial cable from rotating relative to the handgrip device.

8. A handgrip device as defined in claim 1, who two radial portions disposed generally at opposite sides of the inner wall of the first longitudinal section are each generally flat to engage a similarly shaped radial portion of a connector of a coaxial cable in order to prevent the coaxial cable from rotating relative to the handgrip device.

9. A handgrip device as defined in claim 1, further including a third longitudinal section adjacent to an opposite longitudinal end of the second longitudinal section relative to the first longitudinal section for engaging a strain relief grommet for a coaxial cable, the third longitudinal section having an inner wall defining a third channel extending therethrough and communicating with the second channel, the third channel having generally a third diameter which is less than the second diameter of the second channel.

10. A coal cable assembly, comprising:

a coaxial cable including at least one connector coupled to a longitudinal end thereof; and

a handgrip device including;

a first longitudinal section having an inner wall defining a first channel extending therethrough for receiving the connector of the coaxial cable, the first charnel having generally a first diameter, and the inner wall being configured for abutting against the connector of the coaxial cable; and

a second longitudinal section generally adjacent to the first longitudinal section for receiving the coaxial cable, the second longitudinal section having an inner wall defining a second channel extending therethrough and communicating with the first channel, the at least one connector of the coaxial cable having an outer wall to oppose the inroad wall of the first longitudinal section and the coaxial cable having an outer wall to be spaced inwardly from the inner wall of the second longitudinal section, the second channel having generally a second diameter which is greater than the first diameter of the first channel such that a space is maintained between the inner wall of the second channel and the coaxial cable when disposed in the second channel, whereby the space protects the coaxial cable adjacent to the connector from damage when fastening or unfastening the connector.

11. A coaxial cable assembly as defined in claim 10, wherein the first longitudinal section defines at least one hole extending from an outer surface to the inner wall for receiving a fastener therethrough, and wherein an outer wall of the at least one connector defines a recess to coincide with the at least one hole for engaging an end of a fastener to thereby couple the handgrip device to the connector of the coaxial cable.

12. A coaxial cable assembly as defined in claim 10, wherein be first longitudinal section defines two holes disposed generally at opposite sides of the first longitudinal section relative to each other, each of the two holes extending from an outer surface to the inner wall for receiving a fastener therethrough and wherein an outer wall of the at least one connector defines two recesses at opposite sides of the connector relative to each other, each recess to coincide with a respective one of the two holes for coupling the handgrip device to a connector of the coaxial cable.

13. A coaxial cable assembly as defined in claim 11, wherein the fastener is a set screw.

14. A coaxial cable assembly as defined in claim 10, wherein at least one radial portion of the inner wall of the first longitudinal section and at least one portion of the connector of the coaxial cable are shaped for engaging one another to prevent the coaxial cable from rotating relative to the handgrip device.

15. A coaxial cable assembly as defined in claim 10, wherein at least one radial portion of the inner wall of the first longitudinal section is generally flat, and at least one radial portion of the connector of the coaxial cable is generally flat to enable the radial portions to engage one another and thereby prevent the coaxial cable from rotating relative to the handgrip device.

16. A coaxial cable assembly as defined in claim 10, wherein two radial portions disposed on generally opposite sides of the inner wall of the first longitudinal section are each shaped to engage a similarly shaped radial portion of the connector of the coaxial cable to prevent the coaxial cable from rotating relative to the handgrip device.

17. A coaxial cable assembly as defined in claim 10, wherein two radial portions disposed on generally opposite sides of the inner wall of the first longitudinal section are each generally flat to engage a similarly shaped radial portion of the connector of the coaxial cable to prevent the coaxial cable from rotating relative to the handgrip device.
