Kim in view of Huang does not disclose wherein the second accommodating groove is extending in the longitudinal direction from the object side to the image side on the inner peripheral surface of the side wall and both the first accommodating groove and the second accommodating groove form a gap between the outer peripheral surface of the lens and the inner peripheral surface of the lens barrel for electrical wiring to pass through, an image-side end of the second accommodating groove opening axially toward an outside of the lens barrel. Kim in view of Huang and Liu are related because both disclose lens units.
Liu discloses a lens unit (see Fig 9) wherein the second accommodating groove is extending in the longitudinal direction from the object side to the image side on the inner peripheral surface of the side wall (see Fig 9; Para [0029-0031]; a second longitudinal section of the conductive traces 132b extend along the inner peripheral sidewall) and both the first accommodating groove and the second accommodating groove form a gap between the outer peripheral surface of the lens and the inner peripheral surface of the lens barrel for electrical wiring to pass through, an image-side end of the second accommodating groove opening axially toward an outside of the lens barrel (see Fig 9-12; Para [0029-0031]; a groove 132b formed between the outer peripheral surface of the lens units (not shown in Figs) and the inner surface of the lens barrel; at the end of the lens barrel conductive traces continue axially out of the lens barrel, which examiner takes to be the section which holds lenses in 122)
Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date to modify Kim in view of Huang wherein the second accommodating groove is extending in the longitudinal direction from the object side to the image side on the inner peripheral surface of the side wall and both the first accommodating groove and the second accommodating groove form a gap between the outer peripheral surface of the lens and the inner peripheral surface of the lens barrel for electrical wiring to pass through, an image-side end of the second accommodating groove opening axially toward an outside of the lens barrel of Liu for the purpose of minimizing the size of electrical components and integrating seamlessly onto the device (Para [0029])
Regarding claim 42, Kim in view of Huang and Liu disclose a camera module including the lens unit according to claim 41 (Kim: see Fig 1; Para [0040]; a camera module is illustrated having said lens unit).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Hong (US 2021/0199953) discloses a lens unit with electrical conduits through a lens barrel.
