1. A connection device of a portable terminal, the connection device comprising:
- one or more coupling slots provided on a lateral side of the portable terminal;
one or more metal pads mounted on a bottom of the one or more coupling slots; and
a plug including magnets corresponding to the one or more metal pads and a plurality of connection pins between the magnets at a predetermined side,wherein the magnets are arranged to protrude away from the predetermined side of the plug, and inserted into the one or more coupling slots by an attractive force produced between the one or more metal pads and the magnets, thereby coupling the plug to the lateral side of the portable terminal,wherein the connection pins protrude between ends of the magnets and the predetermined side,wherein the connection pins include at least one power pin and at least one ground pin and an end of the ground pin is positioned between the ends of the magnets and an end of the power pin, andwherein an end face of each of the magnets has an asymmetrical shape.
