GROUND OF PORTABLE WIRELESS TERMINAL

摘要

PURPOSE: A ground of a portable wireless terminal is provided to prevent erroneous operation of an RF board due to high voltage by directly grounding high voltage to an inner surface of a casing frame. CONSTITUTION: A plurality of metal domes are installed at one side of a flexible printed circuit board(10). An LCD(130) is integratively installed with the flexible printed circuit board(10) by electrical connection at the upper part of the metal domes. The flexible printed circuit board(10) includes at least one or more metal ground piece(12) protruded to the outside and is fixed on a shield cover(21) of an RF board(20). The RF board(20) is mounted at a main body(100). An inner surface of the main body(100) is applied with a conductive material. If the RF board(20) is mounted on an upper casing frame(111), the metal ground pieces(12) bend by a corner of the frame(111). If the RF board(20) is completely mounted on the upper casing frame(111), the metal ground pieces(12) electrically connect to the inner surface of the casing frame(111) with regular elasticity. High-voltage static electricity flows from the outside of the terminal is grounded to the inner surface of the main body frame(111) applied with the conductive material.
