Abstract

An automatically disconnecting plug has a rotatable drive member with a threaded central aperture. A threaded shaft extends through the central aperture. An electrically conductive coupling member is carried by the shaft. Upon rotation of the drive member, the coupling member is disconnected by being carried by the shaft into the interior cavity of the housing.

Claims (6)

1. An automatically disconnecting plug, comprising:
a housing having an interior cavity with an access opening;
a drive member rotatably mounted within the interior cavity, the drive member having a central aperture defined by a threaded circumferential sidewall having interior threads;
a threaded shaft having exterior threads, a first end and a second end, the shaft extending through the central aperture of the drive member with the exterior threads engaging the interior threads of the threaded circumferential sidewall, such that rotation of the drive member in a first rotational direction causes axial movement of the threaded shaft in a first direction toward the access opening and rotation of the drive member in a second rotational direction causes axial movement of the threaded shaft in a second direction away from the access opening;
an electrically conductive first coupling member carried by the first end of the threaded shaft, the first coupling member being adapted to mate with an external mating second coupling member;
a drive mechanism for selectively rotating the drive member upon a selected triggering event occurring, whereby the first coupling member is carried by the shaft in the second direction away from the access opening and into the interior cavity of the housing and out of engagement with the second coupling member; and a stop on the housing which is adapted to prevent the second coupling member from being drawn into the housing along with the first coupling member.
2. The automatically disconnecting plug as defined in Claim 1, in combination with a selected electrical circuit from an electrical system of a motor vehicle, such that energizing of the selected electrical circuit serves to trigger disconnection by the automatically disconnecting plug, the selected electrical circuit remaining dormant upon an engine of the motor vehicle being started without being placed in motion, a further step being required by an operator of the motor vehicle in order to energize the selected electrical circuit and thereby trigger disconnection by the automatically disconnecting plug.
3. A method of triggering disconnection of an automatically disconnecting plug, comprising the step of:
coupling the automatically disconnecting plug to a selected electrical circuit from an electrical system of a motor vehicle, such that energizing of the selected electrical circuit serves to trigger disconnection by the automatically disconnecting plug, the selected electrical circuit remaining dormant upon an engine of the motor vehicle being started without the vehicle being placed in motion, a further step being required by an operator of the motor vehicle in order to energize the selected electrical circuit and thereby trigger disconnection by the automatically disconnecting plug.
4. The method as defined in Claim 3, the further step by the operator involving the operator sitting in a driver's seat of the motor vehicle.
5. The method as defined in Claim 3, the further step by the operator involving the operator sitting in a driver's seat of the motor vehicle and doing up a seat belt associated with the driver's seat.
6. The method as defined in Claim 3, the further step by the operator involving moving a gear shift lever to a selected triggering position.
