Detachable coupling for a remote inspection device
First Claim
1. A detachable coupling for selectively attaching first and second cables of a remote inspection device, the detachable coupling comprising:
- a first ferrule component provided over the first cable and having an end cap extending over an end of the first cable, said first ferrule component being an electrical insulator;
a first casing engaging said first ferrule component, said first casing and said first ferrule component being secured to the first cable, said first ferrule component providing a seal to inhibit fluid communication between said first casing and the first cable, said first ferrule component electrically isolating said first casing from the first cable;
a first electrical connector supported within said first casing and electrically connected to wires in the first cable;
a second ferrule component provided over the second cable and having an end cap extending over an end of the second cable, said second ferrule component being an electrical insulator;
a second casing engaging said second ferrule component, said second casing and said second ferrule component being secured to the second cable, said second ferrule component providing a seal to inhibit fluid communication between said second casing and the second cable, said second ferrule component electrically isolating said second casing from the second cable; and
a second electrical connector supported within said second casing and electrically connected to wires in the second cable, wherein said first and second casings engage and inhibit relative rotation therebetween, and said first and second electrical connectors engage and electrically connect the wires of the first and second cables.

Abstract
A remote inspection device is provided for inspecting visually obscured locations. The device is generally comprised of a imager housing and a display housing disposed on opposite ends of a modular, flexible cable. An imaging device and one or more light sources are embedded in the end of the cylindrical imager housing. A display housing is coupled to the other end of the flexible cable and configured to be grasped by a user of the device. A display device supported by the display housing receives a video signal from the imaging device and converts the video signal to a video image. The flexible cable can be removably attached to other components with a detachable coupling.
