□ About Insulation and Non-Insulation
Panel-mounted RCA pin jacks, phi 3.5 jacks, etc. are divided into "insulated" and "non-insulated" types. Insulated or non-insulated means "whether the GND terminal of the connector contacts the panel" when the connector is attached to the panel.
For insulated types, the GND terminal of the connector does not connect (contact) with the panel.
The non-insulated type will be electrically connected if the panel is metallic.
Insulated connectors are used when you don't want to create a "GND (ground) loop."
*What is a GND loop?
A loop of wiring, especially a GND line loop, is called a GND loop. When the magnetic flux interchains with the loop, current flows through the GND line, creating a voltage that becomes noise. In such cases, breaking the loop can prevent noise caused by interlocking magnetic flux.
