Abstract

A cable connector for counting a number of plug-in events and preventing further plug in attempts after a threshold number of plug-in events have occurred. An inner sleeve is located inside an outer sleeve, and is designed to move relative to the outer sleeve. The inner sleeve further includes a tab on an outer surface of the inner sleeve. A gear wheel is located inside the outer sleeve and perpendicular to the inner sleeve and has a number of gear teeth. A toggle plug counter rotates the gear wheel one tooth in response to a plug-in action of the cable counter. When the gear wheel rotates to a point where the tab aligns with a notch in the gear wheel an inner spring at the opposite end of the inner sleeve causes the inner sleeve to move through the gear wheel such that further plugging action becomes difficult.

First claim

What is claimed is:

1. A cable connector comprising:
an outer sleeve;
an inner sleeve disposed inside the outer sleeve, the inner sleeve configured to move relative to the outer sleeve, the inner sleeve further including a tab on an outer surface of the inner sleeve;
a gear wheel disposed inside the outer sleeve and perpendicular to the inner sleeve, the gear wheel having a plurality of gear teeth, the gear wheel configured to prevent the inner sleeve from moving until the tab of the inner sleeve aligns with a notch in the gear wheel;
a toggle plug counter configured to interact with the plurality of gear teeth on the gear wheel, the toggle plug counter configured to rotate the gear wheel one tooth in response to a plug-in action of the cable connector;
an inner spring disposed at an end of the inner sleeve opposite the gear wheel, the inner spring configured to cause the inner sleeve to move through the gear wheel in response to alignment of the tab of the inner sleeve and the notch in the gear wheel.

2. The cable connector of claim 1 further comprising:
a middle sleeve, the middle sleeve disposed between the inner sleeve and the outer sleeve; and
wherein the inner sleeve is configured to move relative to the middle sleeve.

3. The cable connector of claim 1 wherein the outer sleeve includes a track to permit the tab of the inner sleeve to move through the outer sleeve.

4. The cable connector of claim 1 wherein the plurality of teeth equal a number equal to a desired threshold number of plug-in events for the cable connector.

5. The cable connector of claim 1 wherein the gear wheel has a second notch and the inner sleeve has a second tab; and
wherein a number of teeth between the notch and the second notch is equal to a number equal to a desire threshold number of plug-in events for the cable connector.

6. The cable connector of claim 1 wherein the toggle plug counter further includes a spring configured to cause the gear wheel to advance one tooth.

7. The cable connector of claim 1 wherein the tab of the inner sleeve includes a portion that is larger than the notch disposed at a location along the tab that when the inner sleeve is moved through the gear wheel the end opposite the inner spring prevents connection of the cable connector.

8. The cable connector of claim 1 wherein the inner sleeve includes at least one feature to prevent the inner sleeve from moving in a direction towards the inner spring.

9. The cable connector of claim 8 wherein a portion of the tab is configured to expand towards the outer sleeve in response to the inner sleeve passing through the notch.

10. The cable connector of claim 8 wherein the at least one feature is a sleeve notch.

11. The cable connector of claim 1 wherein the inner spring has a spring force that is sufficient to cause the cable connector to detach from a connection.

12. A cable system comprising:
a cable including a center conductor and cable insulation;
a cable connector disposed at a first end of the cable, the cable connector having;
an outer sleeve;
an inner sleeve disposed inside the outer sleeve, the inner sleeve configured to move relative to the outer sleeve, the inner sleeve further including a tab on an outer surface of the inner sleeve;
a gear wheel disposed inside the outer sleeve and perpendicular to the inner sleeve, the gear wheel having a plurality of gear teeth, the gear wheel configured to prevent the inner sleeve from moving until the tab of the inner sleeve aligns with a notch in the gear wheel;
a toggle plug counter configured to interact with the plurality of gear teeth on the gear wheel, the toggle plug counter configured to rotate the gear wheel one tooth in response to a plug-in action of the cable connector;
an inner spring disposed at an end of the inner sleeve opposite the gear wheel, the inner spring configured to cause the inner sleeve to move through the gear wheel in response to alignment of the tab of the inner sleeve and the notch in the gear wheel.

13. The cable system of claim 12 wherein the cable connector further comprising:
a middle sleeve, the middle sleeve disposed between the inner sleeve and the outer sleeve; and
wherein the inner sleeve is configured to move relative to the middle sleeve.

14. The cable system of claim 12 wherein the outer sleeve includes a track to permit the tab of the inner sleeve to move through the outer sleeve.

15. The cable system of claim 12 wherein the plurality of teeth equal a number equal to a desired threshold number of plug-in events for the cable connector.

16. The cable system of claim 12 wherein the gear wheel has a second notch and the inner sleeve has a second tab; and
wherein a number of teeth between the notch and the second notch is equal to a number equal to a desire threshold number of plug-in events for the cable connector.

17. The cable system of claim 12 wherein the toggle plug counter further includes a spring configured to cause the gear wheel to advance one tooth.

18. The cable system of claim 12 wherein the tab of the inner sleeve includes a portion that is larger than the notch disposed at a location along the tab that when the inner sleeve is moved through the gear wheel the end opposite the inner spring prevents connection of the cable connector.

19. The cable system of claim 12 wherein the inner sleeve includes at least one feature to prevent the inner sleeve from moving in a direction towards the inner spring.

20. The cable system of claim 12 wherein the cable connector further comprising:
a second cable connector disposed at a second end of the cable, the cable connector having;
an outer sleeve;
an inner sleeve disposed inside the outer sleeve, the inner sleeve configured to move relative to the outer sleeve, the inner sleeve further including a tab on an outer surface of the inner sleeve;
a gear wheel disposed inside the outer sleeve and perpendicular to the inner sleeve, the gear wheel having a plurality of gear teeth, the gear wheel configured to prevent the inner sleeve from moving until the tab of the inner sleeve aligns with a notch in the gear wheel;
a toggle plug counter configured to interact with the plurality of gear teeth on the gear wheel, the toggle plug counter configured to rotate the gear wheel one tooth in response to a plug-in action of the cable connector;
an inner spring disposed at an end of the inner sleeve opposite the gear wheel, the inner spring configured to cause the inner sleeve to move through the gear wheel in response to alignment of the tab of the inner sleeve and the notch in the gear wheel.
