Description

Technical Field

[0001] The utility model belongs to the technical field of shielding covers, and in particular relates to a multi-layer shielding cover with a heat dissipation mechanism. Background Art

[0002] A shielding cover is a tool used to shield electronic signals. Its function is to shield the influence of external electromagnetic waves on internal circuits and the outward radiation of electromagnetic waves generated internally. Cable connectors also need to be electromagnetically shielded during use, and this is when a shielding cover is needed.

[0003] However, when the cable connector is exposed to the outside air, oxidation will occur at the connector, which will cause the connection between the two cables to heat up. When the cable connection interface is set inside the shielding cover, the heat cannot be dissipated, causing heat to accumulate inside the shielding cover and damage the shielding cover.
