Abstract

A plug-jack type transfer device includes: at least seven electric terminals for connecting a mini single-head electric plug to the transfer device and exchanging an electrical signal therewith; a container body for containing and supporting the electric terminals and receiving the mini single-head electric plug; and a switch mechanism which completes electrical connection between a fourth electric terminal and a sixth electric terminal when the mini single-head electric plug is inserted into the container body. The mini single-head electric plug includes at least seven regions. A region farthest from a plug tip electrode corresponds to a first region. When the mini single-head electric plug is inserted, a first electric terminal comes in contact with the first region; a second electric terminal with a seventh region; a third electric terminal with a fifth region; the fourth electric terminal with a third region; a fifth electric terminal with the third region; and a seventh electric terminal with the first region. The first, fourth, and fifth electric terminals are coupled to a power level via respective resistors, and the sixth and the seventh electric terminals are grounded.
