  Hereinafter, embodiments of the present invention will be described with reference to the drawings showing examples. The radio wave shielding cases for portable electronic devices of the present invention shown in Examples 1 to 4 (FIGS. 1 to 9) and Examples 9 to 10 (FIGS. 25 to 29) basically store mobile communication devices one by one. Main body 1 having a storage opening that can be closed, lid body 2 that can be fitted to the storage opening of main body 1 and closed, and an annular shield member that is interposed between the fitting contact portion of main body 1 and lid body 2 3 and a holding mechanism 4 that maintains the closed state. And on the lid back side of the lid body 2, there is a lid body 2 having an inner lid portion 22 that fits and protrudes into the storage port of the main body 1, and is made of a conductive material along the storage port or the inner lid portion 22. An annular shield material 3 is arranged. In the closed state, the shield material 3 is compressed to at least 10 volume% or more, preferably 20 to 30 volume% or more, thereby forming a sealed housing space S that fills a gap through which radio waves pass. Is done. Further, the holding state 4 is maintained reliably by the holding mechanism 4 that maintains the closed state of the main body 1 and the lid body 2.

  In addition, the radio wave blocking locker for portable electronic devices of the present invention shown in Embodiments 5 to 8 (FIGS. 10 to 24) basically collects a plurality of boxes 53 that can store portable communication devices one by one. It is comprised from the main body 1 opened and accommodated in one accommodation port, and the cover body 2 which can be fitted to the accommodation port of the main body 1, and can be closed. The lid 2 has a lid 2 having an inner lid portion 22 that fits and protrudes into the storage port of the main body 1 on the back side of the lid body 2, and is electrically conductive around the storage port or the inner lid portion 22. An annular shield material 3 made of a material is disposed. In the closed state, the shielding material 3 is compressed to 10% by volume or more, so that a sealed accommodation space S in which a gap through which radio waves pass is filled is formed. Further, the holding state 4 is reliably maintained by the holding mechanism 4 that maintains the closed state of the box 5 and the lid 2.

  In both the radio wave shielding case for portable electronic devices and the radio wave blocking rocker for portable electronic devices, the sealed housing space S is composed of only a conductive material surface on the inner surface of the case and the back surface of the lid 2 with no gaps. In addition, the boundary between the inner surface of the case and the lid 2 is a closed space that is blocked by a shield material. As a constituent material, any material can be used as long as it is a conductive material such as a conductive metal, conductive resin, conductive fiber, etc., but it has electromagnetic shielding properties such as aluminum and stainless steel, and A metallic material excellent in workability is used.

  For example, the inner surface of the case and the back surface of the lid body 2 can be integrally formed by the constituent surfaces of the conductive material, and the outer member exposed to the case outer eyes and the outer surface of the lid body 2 can be composed of a nonconductive material. As another form, the entire main body 1 or the entire lid body 2 may be integrally formed of a conductive material.

  The shield member is made of an annular conductive material, and is provided in one of the concave portions of the main body 1 or the lid body 2 or on the other convex portion. It is arranged on one of the peripheral surfaces and is sealed and compressed to ensure sealing performance. This compression ratio is required to be at least 10% or more at the time of release in volume ratio, and is preferably designed to be a compression ratio in the range of 20 to 30%. When the compression ratio is less than 10%, a minute gap is generated between the surface of the shield member 3 and the contacted target surface due to the fine protrusions on the surface. If the compression rate exceeds 50%, an excessive elastic reaction force is generated. Therefore, considering the workability at the time of closing, the compression rate is preferably 40% or less, more preferably 30% or less.

  Various shapes can be selected as the shape of the sealed housing space by the main body 1 and the lid body 2 or the box body 53 and the lid body 2, and a partition or an impact buffering material may be provided inside. The surface may be constituted by a radio wave shielding material.

  When forming a half or a box of the accommodation space S by bonding of conductive materials, a conductive shielding material is placed along the bonding boundary, and a conductive adhesive or a conductive welding material is used. It is preferable to fix. When the half of the housing space S or the box is integrally formed by molding of the conductive material instead of bonding of the conductive material, a piece of material made of a material having extensibility, such as a metal having high electrical conductivity, is used. The plate-shaped raw material can be obtained by deep drawing into a cube, a polygonal column, or a cylindrical shape. In particular, the molding by deep drawing can surely suppress the generation of gaps, and can maximize sealing performance and shielding effect.

The cylindrical outer peripheral side surface of the inner lid portion 22 is tapered so as to be slightly reduced in diameter in the protruding direction (downward), and the cylindrical inner peripheral side surface of the outer lid portion 21 is slightly toward the lower end. A taper is formed to increase the diameter. These tapers are formed with inclined surfaces within 1 degree in the direction of the axis opposite to each other along the inner and outer surfaces of the opening tip 11E that is gently curved, so that the opening tip 11E is securely fitted into the lid groove 2D. In addition, the inner and outer peripheral surface contact portions are reliably ensured in the fitted state.

  An elastic shield member 3 that is in contact with the lower surface of the top plate 210 and is connected in an annular shape is embedded in the lid groove 2D. The shield member 3 is formed of an annular body in which the circumference of an elastic core member having a circular cross section made of neoprene or silicon elastomer resin is covered with a metal net material made of iron, copper, or tin alloy. For example, a material having a compressibility of 30% at 20 psi and 50% at 40 psi can be used.
