Insulator design for video inspection devices

摘要

A method is provided for manufacturing a remote video inspection device. The method includes: applying an insulating coating to an exterior surface of a conduit; forming an imager housing on one end of the conduit using an overmolding process, the imager housing having a cavity configured to receive a circuit board assembly having an imaging device disposed thereon; feeding wires through the conduit and electrically coupling the wires to the circuit board assembly; inserting the circuit board assembly into the cavity of the imager housing; affixing a cap over the cavity of the imager housing; sliding an insulating finger guard over an opposing end of the conduit; affixing the finger guard along the conduit at a location proximate to the opposing end of the cable, such that the finger guard extends radially outward from the cable; and attaching a connector to the opposing end of the conduit. In this way, the remote inspection device has been designed to meet certain electrical safety standards.

主权项

1. A remote inspection device, comprising:
a circuit board assembly having an imaging device disposed at an outwardly facing end of the circuit board assembly, the imaging device being operable to capture an image of a viewing area proximate to the outwardly facing end of a flexible cable and convert the image into a video signal; a display housing having an image processor adapted to receive the video signal from the imaging device and operable to convert the video signal to a video image for display on a display device residing in the display housing; the cable having a first end coupled to the circuit board assembly and a second end coupled to the display housing, the cable comprised of a metal conduit encased by an insulating material and housing a plurality of wires therein, where the wires operably connect the imaging device to the power source and the image processor, the insulating material having a first layer and a second layer, wherein the first layer extends along the cable toward the first end beyond the second layer; an imager housing encasing the circuit board assembly and encircling a portion of the first end of the cable; and a finger guard that extends radially outward from the cable and positioned along the cable at a location proximate to the display housing, wherein the finger guard has a hole passing therethrough for receiving the cable.
