AI Technical Summary

Technical Problem

Existing passive device housings are prone to deformation and cracking when subjected to external mechanical stress, and the limited internal space of the housing makes it difficult to miniaturize the devices.

Method used

Design a passive device housing with reinforcing ribs, including a housing body and reinforcing ribs, setting an expansion cavity and a main mounting cavity, and forming a heat dissipation channel through a through connection hole. Use conductive coating and corrugated surface structure to improve housing strength and heat dissipation performance.

Benefits of technology

It achieves miniaturization and improved stability of passive components, enhances the deformation resistance and anti-interference performance of the housing, and improves heat dissipation and aesthetics.
