SHIELD STRUCTURE OF WIRELESS COMMUNICATION DEVICE

摘要

PURPOSE: A shield structure of a wireless communication device is provided to avoid deterioration of shield effect by stably connecting a chassis and a circuit board with a lead pattern. CONSTITUTION: A shield structure of a wireless communication device comprises a circuit board(100) and a chassis. A lead pattern(110) is formed along the outer boundary of the circuit board(100). The circuit board(100) includes four via-holes(120) near its four corners. Only some part of each of the via-holes(120) is overlapped with the lead pattern(110). The chassis is mounted on the circuit board(100) for shielding. The chassis is connected to the circuit board(100) with the lead pattern(100) and has four legs to be inserted into the via-holes(120). The legs have L type cross sectional shapes so as to avoid connection failure with the lead pattern(110) at joint between the circuit board(100) and the chassis.
