Abstract

This cable connection structure (1) connects one or more cables (20) and an electrode provided on a substrate (10), wherein the cables (20) are provided with: a core wire (21) comprising a linear electroconductive material; a tubular interior insulating body (22) comprising an insulator, said insulating body (22) covering the outer circumference of the core wire (21); a shield (23) extending in the longitudinal direction of the interior insulating body (22), the shield (23) comprising a plurality of conductors covering the outer circumference of the interior insulating body (22), and an exposure section exposing the interior insulating body (22) being formed in the shield (23); and an exterior insulating body (24) comprising an insulator for covering the outer circumference of the shield (23). The shield (23), including the formation area for the exposure section, the interior insulating body (22), and the core wire (21) are incrementally more exposed to the exterior toward the tip. The substrate (10) is provided with a first electrode (11) that is electrically connected to the core wire (21) and a second electrode (12) that is electrically connected to the shield (23).

Description

Technical field [0001] The present invention relates to a cable connection structure for connecting a cable and a substrate. Background technique [0002] In the past, digital cameras and digital video cameras have been used in various devices such as mobile phones with imaging functions and endoscopic devices for observing the inside of the organs of the subject, using boards and cables for mounting electronic components. A cable connection structure for connecting wires. [0003] Among them, the endoscope device has: a slender insertion instrument that is flexible and is inserted into the subject's body to obtain image signals inside the organ; and a signal processing unit that is connected to the insertion instrument to perform image signals Signal processing. To the tip portion of the insertion instrument, an imaging unit composed of a substrate on which imaging elements having a plurality of pixels are mounted, and a cable whose one end is connected to the signal processing ...
