发明名称 ELECTROMAGNETIC WAVE SHIELDING CABINET, ITS MANUFACTURE AND METAL MOLD EQUIPMENT
摘要 PROBLEM TO BE SOLVED: To prevent reflection of electromagnetic wave and generation of standing wave in the shielded inside, by partly burying conductive material in a part facing a high frequency circuit, in a resin molded object including the high frequency circuit. SOLUTION: An electromagnetic wave shielding cabinet 10 consists of a lower cabinet 16 and an upper cabinet 17 which are made of plastic. A thin plate molded object 18 composed of conductive material for electromagnetic wave shielding is partly buried in the inner surface side of the lower cabinet 16. The thin plate molded object 18 and a resin molded object 19 are integrally molded in an unified body. The thin plate molded object 18 is arranged facing a high frequency circuit part 11 and is not arranged in a low frequency circuit part 12. Thereby electromagnetic wave is not reflected and standing wave is not generated in the shielded inside, so that malfunction and operation failure may not occur in the high frequency circuit part 11 and other circuit parts and noise generation can be prevented.
