Abstract: A mechanical device that indicates prior mating. The device comprises a first part having a first conductive device movable from a first position to a second position and a plurality of second conductive devices, and a second mating part including a plurality of third conductive devices mateable to the plurality of second conductive devices. On initial mating of the first and second part, the second part causes the movable first conductive device to move from the first position to a second position where it is captured, while closing a circuit that causes a signal to be sent. Further mating of the first and second parts connects the plurality of second conductive devices to the plurality of third conductive devices. In subsequent unmating and remating of the first and second parts, the first conductive device, being captured in its second position, does not result in a circuit closing before the plurality of second conductive devices mate with the third conductive devices.

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.

Abstract: A generally circular plug and receptacle connector system for use with electronic systems and devices is provided. This system includes: a plug component and a receptacle component. The plug component further includes: a housing having an internal channel formed therein for receiving a length of stripped wire; a shielded conduit attached to the housing, wherein the shielded conduit further includes a chamber formed therein; a plug body disposed within the shielded chamber; and a plurality of conductive pins disposed within the plug body, wherein the conductive pins are adapted on one end to be coupled with the length of stripped wire.
