Abstract

A coaxial cable connector includes a connector body and a coupling nut on the connector body, and a radio frequency interference shield fit to the coupling nut. The radio frequency interference shield includes a front end and a rear end, a bellows section proximate the rear end, and a concave conical section proximate the front end. The concave conical section terminating in an open mouth configured to receive a female coaxial port.

Claims

1. A coaxial cable connector comprising:

a connector body and a coupling nut on the connector body;

a radio frequency interference shield fit to the coupling nut, wherein the radio frequency interference shield comprises;

a front end and a rear end, wherein the rear end is fit to the coupling nut;

a bellows section proximate the rear end; and

a concave conical section proximate the front end, the concave conical section terminating in an open mouth configured to receive a female coaxial port.

2. The coaxial cable connector of claim 1, wherein the bellows section compresses axially in response to application of the female coaxial port through the radio frequency interference shield.

3. The coaxial cable connector of claim 1, wherein the concave conical section enlarges axially in response to application of the female coaxial port through the radio frequency interference shield.

4. The coaxial cable connector of claim 1, wherein the shield produces audible feedback in response to application of the female coaxial port through the radio frequency interference shield.

5. The coaxial cable connector of claim 1, wherein the radio frequency interference shield moves between a neutral condition and a deformed condition in response to application of a female coaxial port through the radio frequency interference shield toward the coupling nut, the deformed condition defined by the radio frequency interference shield having a shorter axial length than in the neutral condition.

6. The coaxial cable connector of claim 1, further comprising:

a convex conical section behind the concave conical section;

a constriction point between the concave conical section and the convex conical section, the constriction point having an outer diameter; and

an outer diameter of the mouth which is greater than the outer diameter of the constriction point.

7. The coaxial cable connector of claim 6, wherein the outer diameter of the constriction point increases, and the outer diameter of the mouth decreases, in response to application of the female coaxial port through the radio frequency interference shield.

8. The coaxial cable connector of claim 6, wherein:

the coupling nut has an outer diameter;

the outer diameter of the mouth is greater than the outer diameter of the coupling nut; and

the outer diameter of the constriction point is smaller than the outer diameter of the coupling nut.

9. The coaxial cable connector of claim 8, wherein the constriction point is axially spaced-apart and in front of the coupling nut.

10. A coaxial cable connector comprising:

a connector body and a coupling nut on the connector body;

a radio frequency interference shield fit to the coupling nut, wherein the radio frequency interference shield moves between a neutral condition and a deformed condition in response to application of a female coaxial port through the radio frequency interference shield toward the coupling nut;

wherein the radio frequency interference shield includes;

a front end and a rear end, wherein the rear end is fit to the coupling nut;

a bellows section proximate the rear end; and

a concave conical section proximate the front end, the concave conical section terminating in an open mouth configured to receive the female coaxial port.

11. The coaxial cable connector of claim 10, wherein, during movement of the radio frequency interference shield from the neutral condition to the deformed condition, the bellows section compresses axially.

12. The coaxial cable connector of claim 10, wherein, during movement of the radio frequency interference shield from the neutral condition to the deformed condition, the concave conical section enlarges axially.

13. The coaxial cable connector of claim 10, wherein, during movement of the radio frequency interference shield from the neutral condition to the deformed condition, the shield produces audible feedback.

14. The coaxial cable connector of claim 10, wherein in the deformed condition, the radio frequency interference shield has a shorter length than in the neutral condition.

15. The coaxial cable connector of claim 10, further comprising:

a convex conical section behind the concave conical section;

a constriction point between the concave conical section and the convex conical section, the constriction point having an outer diameter; and

an outer diameter of the mouth which is greater than the outer diameter of the constriction point.

16. The coaxial cable connector of claim 15, wherein, during movement of the radio frequency interference shield from the neutral condition to the deformed condition, the outer diameter of the constriction point increases and the outer diameter of the mouth decreases.

17. The coaxial cable connector of claim 15, wherein:

the coupling nut has an outer diameter;

in the neutral condition, the outer diameter of the mouth is greater than the outer diameter of the coupling nut; and

in the neutral condition, the outer diameter of the constriction point is smaller than the outer diameter of the coupling nut.

18. The coaxial cable connector of claim 17, wherein the constriction point is axially spaced-apart and in front of the coupling nut.

19. A female coaxial port comprising:

a body having a base, the body for receiving a coaxial cable connector;

a radio frequency interference shield fit to the body, wherein the radio frequency interference shield moves between a neutral condition and a deformed condition in response to application of the coaxial cable connector to the body through the radio frequency interference shield;

wherein the radio frequency interference shield includes;

a front end and a rear end, wherein the rear end is fit to the body;

a bellows section proximate the rear end; and

a concave conical section proximate the front end, the concave conical section terminating in an open mouth configured to receive the coaxial cable connector.

20. The female coaxial port of claim 19, further comprising:

a convex conical section behind the concave conical section;

a constriction point between the concave conical section and the convex conical section, the constriction point having an outer diameter;

an outer diameter of the mouth which is greater than the outer diameter of the constriction point;

an outer diameter of the body which is greater than the outer diameter of the body; and

in the neutral condition, the outer diameter of the constriction point is smaller than the outer diameter of the body.
