In addition to the AV connector specifications on mobile devices, the diameter of the general AV connector configured on computer devices is also 3.5mm. The computer terminal interface is a stereo AV plug. There are three metal contacts on the wire plug, and there are two circles of insulators between the contacts as an isolation layer to prevent coupling and crosstalk. The wire plugs are arranged in the order of contacts: top - left channel; middle - right channel; low end - common end (also known as the ground end). Among them, the ground terminal is the longest contact with the largest area. The order of the arrangement of each contact in the plug corresponds to the plug.
