Abstract

An electrical connector having a mechanical mating cycle limitation that renders the connector inoperable after a predetermined number of mating cycles is disclosed. The electrical connector includes a rotating component that rotates within the connector for the predetermined number of mating cycles until the rotating component is prohibited from further rotation, which prevents the connector from further mating, thereby rendering the connector inoperable.

Claims

1. An electrical connector having a mechanical mating cycle limitation for providing an electrical connection to a receptacle assembly, comprising:

a plug housing comprising an insertion portion, a shell, and inner ramps disposed therewithin;

contacts disposed within the plug housing;

a midpiece comprising outer ramps disposed therewithin, the midpiece securely assembled to the plug housing; and

a plunger component, a rotating component, and a spring disposed within the securely assembled midpiece and plug housing;

wherein the rotating component is configured to rotate within the electrical connector when mating and unmating the electrical connector to the receptacle assembly for a predetermined number of mating cycles until the rotating component is prohibited from further rotation during a mating cycle, thereby rendering the electrical connector inoperable.

2. The electrical connector of claim 1, wherein the rotating component is urged towards the outer ramps by the plunger when the electrical connector is mated to the receptacle assembly.

3. The electrical connector of claim 1, wherein the rotating component is urged towards the inner ramps by the spring when the electrical connector is unmated from the receptacle assembly.

4. The electrical connector of claim 1, wherein a stop surface is disposed within the inner ramps that contacts a drive lug disposed on a surface of the rotating component when mating the electrical connector to the receptacle assembly so as to prohibit the plunger from being urged towards the rotating component thereby prohibiting the electrical connector from mating to the receptacle assembly after the predetermined number of mating cycles.

5. The electrical connector of claim 1, further comprising a visual indicator on the electrical connector displaying the number of mating cycles the electrical connector has performed.

6. The electrical connector of claim 1, further comprising a hole in the connector configured to provide access for a tool to engage the rotating component to prevent the rotating component from rotating within the electrical connector during a mating cycle.

7. The electrical connector of claim 1, further comprising a strain relief device.

8. A method of preventing the mating of an electrical connector after a predetermined number of mating cycles, thereby rendering the electrical connector inoperable, comprising:

providing an electrical connector comprising;

a plug housing comprising an insertion portion, a shell, and inner ramps disposed therewithin;

contacts disposed within the plug housing;

a midpiece comprising outer ramps disposed therewithin, the midpiece securely assembled to the plug housing; and

a plunger, a rotating component, and a spring disposed within the securely assembled plug housing and midpiece;

wherein the rotating component is configured to rotate within the electrical connector when mating and unmating the electrical connector to the receptacle assembly for a predetermined number of mating cycles until the rotating component is prohibited from further rotation during a mating cycle, thereby preventing the electrical connector from further mating to the receptacle assembly, thereby rendering the electrical connector inoperable; and

mating and unmating the electrical connector to the receptacle assembly for the predetermined number of mating cycles until the electrical connector is rendered inoperable.

9. The method of claim 8, wherein the rotating component is urged towards the outer ramps by the plunger when the electrical connector is mated to the receptacle assembly.

10. The method of claim 8, wherein the rotating component is urged towards the inner ramps by the spring when the electrical connector is unmated from the receptacle assembly.

11. The method of claim 8, wherein a stop surface is disposed within the outer ramps that contacts a drive lug disposed on a surface of the rotating component when mating the electrical connector to the receptacle assembly so as to prohibit the plunger from being urged towards the rotating component thereby prohibiting the electrical connector from mating to the receptacle assembly after the predetermined number of mating cycles.

12. The method of claim 8, further comprising a visual indicator on the electrical connector displaying the number of mating cycles the electrical connector has performed.

13. The method of claim 8, further comprising a hole in the connector configured to provide access for a tool to engage the rotating component to prevent the rotating component from rotating within the electrical connector during a mating cycle.

14. The method of claim 8, further comprising a strain relief device.
