Patent ID: 8393921

Claim:
A receptacle connector, comprising: a shell having an opening; and an insulative housing being enveloped in said shell and defining at least one receiving room to said opening; and a set of first principal terminals including a plurality of first principal terminals disposed in said insulative housing wherein each of said first principal terminal having a contact at front end and a soldering tail at rear end thereby arranging contacts of said first principal terminals in single row; and a set of second principal terminals including a plurality of second principal terminals disposed in said insulative housing wherein each of said second principal terminal having a contact at front end and a soldering tail at rear end thereby arranging contacts of said second principal terminals in single row; and a supplementary terminal disposed in said insulative housing wherein said supplementary terminal having a tip at front end and a soldering tail at rear end; and all said tip of said supplementary terminal and said contacts of said principal terminals being exposed in said receiving room; and as a plug connector plugging via said opening into said receiving room, a contact zone at front end of said plug terminal electrically connecting with the contact of said second principal terminal and also electrically connecting with said tip of said supplementary terminal, configuring a loop between said second principal terminal and said supplementary terminal, thereby providing a bridge between the soldering tail of said second principal terminal and said soldering tail of said supplementary terminal transmitting auxiliary signal to a host board embedded in a electric machine system.
