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