More Information
Summary:An electronic endoscope has an insert section to be introduced into a human body cavity. A distal portion of the insert section contains a CCD and a printed circuit board to which the CCD is bonded. In the insert section, a cable bundle being a bundle of coaxial cables extends. Each coaxial cable consists of a signal line, insulation surrounding the signal line, a braided wire surrounding the insulation, and an insulating jacket. The cylindrical braided wire is stranded into a single line, and is soldered as a ground line to a ground terminal of the printed circuit board. The signal line is pulled out of the coaxial cable with a length longer than the ground line. The signal line is soldered to an input/output terminal of the printed circuit board with a larger sag than the ground line.
