Patent ID: 7354286

Claim:
An adapter for establishing an electrical connection between connectors and sockets of different specifications, the adapter having an insertion side with a plurality of ports for insertion of conductive terminals of the connectors and a coupling side for insertion into the sockets, comprising: a housing trough located on the coupling side in an indented manner; and a first terminal set and a second terminal set, each set having terminals of different specifications, and each terminal having a pivotable base which moves the terminal between an open and a retracted position, whereby the pivotable bases for the first and second terminal sets are located on opposite sides of the housing trough so that the first and second terminals move in a direction crosswise to one another, whereby the terminal sets are held in the housing trough when in a retracted condition, and whereby either terminal set can be inserted into a corresponding socket when in an open position, wherein the first terminal set and the second terminal set include respectively flat parallel blade terminals and round parallel pin terminals, wherein the coupling side has a rectangular grounding terminal pivotally coupled on a desired location to allow the round parallel pin terminals to be inserted into a socket with three insertion ports, and wherein the rectangular grounding terminal is made from an insulation material.
