AI Technical Summary

Technical Problem

The aluminum alloy electromagnetic shielding shell of traditional video converters is difficult to completely seal the gaps at the splicing points, allowing electromagnetic waves to penetrate and affecting the video conversion effect and stability.

Method used

The gap sealing component consists of an elastic rubber strap, a frame-shaped conductive foam board, and a conductive foam frame. Combined with an elastic compression component, it tightly seals the gaps at the joint between the aluminum alloy electromagnetic shielding shell and the end plate through double elastic force.

Benefits of technology

It effectively improves electromagnetic shielding performance, prevents electromagnetic wave penetration and signal interference, reduces problems such as screen flicker and snow, and prevents internal signal leakage, thus extending the service life and stability of the equipment.
