PURPOSE:To obviate giving influence to the inside despite accidental touching by hermetically closing the opening part of the exteror by the conductive rubber, inserting the connector of other electronic apparatus, pressure contacting the conductive rubber to the inside terminal by its conductor and performing electrical connection between the conductor and internal terminal. CONSTITUTION:Aconductive rubber sheet 10 consisting of pressure sensitive conductive rubber is compression bonded to the back cover at the periphery of the inside surface of a terminal opening part 5 by the ring form protrusion 11 on the movement, whereby the entry of water through the opening part is prevented. While no external apparatus is connected, the internal terminal 9 and conductive rubber 10 are kept apart. When the connectors 12 thru 14 of the external electronic apparatus are connected, its connector conducting bar 13 pressure contacts the conductive rubber 10 to the internal terminal 9, thus sufficiently lower the electric resistance between both and conducting both. The abovementioned conductive rubber 10 is pressure sensitive conductive rubber which exhibits insulation characteristic in a free state but shows conductivity of only the portion where pressure is applied. |
