AI Technical Summary

Technical Problem

Existing camera devices are susceptible to electrostatic discharge (ESD) that can cause current to flow inside the case, potentially affecting the substrate, especially due to the unstable shape of the insulating adhesive, which fails to stably reduce the influence of static electricity.

Method used

The camera device is constructed with a conductive lens barrel and case, using a conductive portion to provide electrical connection between the lens barrel and the case, and an insulating adhesive to seal the space, ensuring current flows through conductive paths instead of air, minimizing impact on the substrate.

Benefits of technology

This configuration effectively minimizes the impact of electrostatic discharge on the substrate by directing current through conductive pathways, stabilizing the adhesive curing, and maintaining the optical axis alignment.

Abstract

Even if electrostatic discharge occurs in the lens, the effect of static electricity on the substrate enclosed in the case is reliably reduced. [Solution] The camera device comprises a case made of a conductive material that encloses a substrate, and a lens barrel made of a conductive material. The camera device comprises a peripheral portion provided along the outer circumference of the lens barrel, and an insulating adhesive that bonds the case and the peripheral portion and is located on the inner circumference side of the peripheral portion. The camera device comprises a conductive portion that provides electrical connection between the outer circumference side of the peripheral portion and the case. The conductive portion is formed integrally with the case or the lens barrel.
