Generally, electromagnetic waves can adversely affect the operation of various electronic devices such as a mobile phone, a telephone, a navigation system, and MP3. Such phenomenon is referred to as EMI (Electro Magnetic Interference) phenomenon, But also harmful to human body.

Therefore, in recent years, an electronic part such as a memory chip mounted on a printed circuit board (PCB) built in an electronic device is covered with a shield case to shield EMI generated from the electronic part, So that it does not affect the operation of other electronic devices.

In order to cover the electronic parts, the shield case is fixed to the printed circuit board by soldering or the like to the printed circuit board. In order to fix the shield case to the printed circuit board, A fixture is required to be fixedly installed.

According to Korean Utility Model Registration Utility Model No. 20-437540, a shielding case fixing mechanism for a printed circuit board is provided so as to facilitate the fixing operation of a shielding case installed on a printed circuit board for shielding electromagnetic interference.

The shielding case fixing mechanism is configured such that a plurality of fixing mechanisms having a plurality of clamping portions along the periphery of the shielding case are installed on the printed circuit board, and then the side walls of the shielding case are inserted into the clamping portion and fixed.

However, such a conventional shielded case fixing mechanism is disadvantageous in that it is difficult to keep the mounting position constant since a plurality of fixing mechanisms must be provided at certain positions on the printed circuit board on which the shielding case is located.

In addition, there is a problem that the shielding rate may be lowered by forming a gap by separating the lower part of the shielding case from the printed circuit board by the fixing mechanism installed on the printed circuit board for fixing the shielding case.
