Description

本発明は、電磁波を遮蔽することができる容器に関するものである。 The present invention relates to a container capable of shielding electromagnetic waves.

従来より、例えば電子部品等を収容する容器には、電磁波を遮蔽する電磁波遮蔽性が求められている（例えば、特許文献１参照）。特許文献１の容器は、上側部材と下側部材とで構成されている。上側部材は、上壁部と下方へ延びる周壁部とを備えており、導電体で構成された導電体層が上壁部と周壁部の厚み方向中間部に設けられている。この導電体層は、周壁部の下端面を覆うようにも設けられている。また、下側部材は、下壁部と上方へ延びる周壁部とを備えており、同様に導電体層が下壁部と周壁部に設けられている。この下側部材の導電体層は、周壁部の上端面を覆うようにも設けられている。上側部材の周壁部の下端面の凸部と下側部材の周壁部の上端面の凹部とが嵌合して１つの容器を構成している。 2. Description of the Related Art Conventionally, for example, containers that store electronic components or the like have been required to have electromagnetic shielding properties that shield electromagnetic waves (see, for example, Patent Document 1). The container of patent document 1 is comprised by the upper side member and the lower side member. The upper member includes an upper wall portion and a peripheral wall portion extending downward, and a conductor layer made of a conductor is provided in an intermediate portion in the thickness direction of the upper wall portion and the peripheral wall portion. This conductor layer is also provided so as to cover the lower end surface of the peripheral wall portion. Further, the lower member includes a lower wall portion and a peripheral wall portion extending upward, and similarly, a conductor layer is provided on the lower wall portion and the peripheral wall portion. The conductor layer of the lower member is also provided so as to cover the upper end surface of the peripheral wall portion. A convex portion on the lower end surface of the peripheral wall portion of the upper member and a concave portion on the upper end surface of the peripheral wall portion of the lower member are fitted to constitute one container.

特開平６−１６９１９０号公報JP-A-6-169190

ところで、特許文献１のように上側部材と下側部材を組み合わせて１つの容器を構成する場合には、両部材の結合構造が問題となる。すなわち、上側部材と下側部材との間に、仮に隙間が生じた場合には、上側部材の周壁部下端面の導電体層と、下側部材の周壁部上端面の導電体層とが離れることになり、それらの間を電磁波が通ってしまい、電磁波の遮蔽性が低下する結果となる。 By the way, when a single container is configured by combining the upper member and the lower member as in Patent Document 1, the coupling structure of both members becomes a problem. That is, if a gap is generated between the upper member and the lower member, the conductor layer on the lower end surface of the peripheral wall portion of the upper member is separated from the conductor layer on the upper end surface of the peripheral wall portion of the lower member. As a result, electromagnetic waves pass between them, resulting in a decrease in shielding properties of the electromagnetic waves.

特に、容器を構成する部材を軽量化の観点から樹脂製とする場合には、例えば熱変形や経年変化等による変形に起因して上側部材と下側部材との間に隙間が生じやすくなる。また、容器に例えば電気自動車用のバッテリー等のような重量物を収容する場合には、その重量により容器を構成する部材が変形して上側部材と下側部材との間に隙間が生じてしまうこともある。しかしながら、特許文献１の容器では、上側部材と下側部材とが単純な凹凸嵌合であるため、両部材の開きを有効に防止できる構造とはなっていない。 In particular, when the member constituting the container is made of resin from the viewpoint of weight reduction, a gap is likely to be generated between the upper member and the lower member due to, for example, deformation due to thermal deformation or aging. In addition, when a heavy object such as a battery for an electric vehicle is accommodated in the container, a member constituting the container is deformed by the weight, and a gap is generated between the upper member and the lower member. Sometimes. However, in the container of Patent Document 1, since the upper member and the lower member are simple concave-convex fitting, it is not a structure that can effectively prevent the opening of both members.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、樹脂製の部材を含む複数の部材で電磁波遮蔽容器を構成する場合に、それら部材間に隙間が生じないようにするとともに、各部材の導電部分が離れないようにして電磁波の遮蔽性を良好に維持することにある。 The present invention has been made in view of such a point, and the object of the present invention is to prevent a gap from being formed between members when an electromagnetic wave shielding container is constituted by a plurality of members including resin members. In addition, the electromagnetic wave shielding property is maintained well so that the conductive portions of the members are not separated.

上記目的を達成するために、本発明では、複数の部材を締結部材によって締結するようにし、さらに、複数の部材の合わせ部において各部材の導電部分を接触させるようにした。 In order to achieve the above object, in the present invention, a plurality of members are fastened by a fastening member, and the conductive portions of the respective members are brought into contact with each other at a joining portion of the plurality of members.

The electromagnetic wave shielding container 1 is a large container that can accommodate, for example, a battery (article) mounted on an electric vehicle. The electromagnetic shielding container 1 may contain, for example, an electronic component that is weak against electromagnetic waves, or an electronic component that generates electromagnetic waves, in addition to the battery of the electric vehicle. Moreover, the magnitude | size of the electromagnetic shielding container 1 can be arbitrarily set according to the thing to accommodate.

電磁波遮蔽容器１は、下側部材１０と上側部材２０とが結合されてなるものであり、下側部材１０及び上側部材２０によって内部に物品の収容空間Ｒが区画形成される。下側部材（本発明の第２部材）１０は、電磁波遮蔽容器１の上下方向略中央部よりも下側部分を構成するものであり、上方に開放する凹状をなしている。凹状の部材は、下側部材１０と上側部材２０との一方であってもよい。この場合、他方の部材は蓋状に成形する。 The electromagnetic wave shielding container 1 is formed by combining a lower member 10 and an upper member 20, and an accommodation space R for articles is defined in the interior by the lower member 10 and the upper member 20. The lower member (second member of the present invention) 10 constitutes a lower portion than the substantially central portion in the vertical direction of the electromagnetic shielding container 1 and has a concave shape that opens upward. The concave member may be one of the lower member 10 and the upper member 20. In this case, the other member is formed into a lid shape.

図２に示すように、下側部材１０は、底壁部１１と、底壁部１１の周縁部から上方へ延びる周壁部１２と、周壁部１２の上端部（上側部材２０と結合される側）から収容空間Ｒの外方へ延びる第１締結部としての下側フランジ部１３とを備えている。底壁部１１、周壁部１２及び下側フランジ部１３は、非導電性を有する樹脂材を用いて一体成形されている。底壁部１１は、略平坦で、平面視で略矩形状に形成されている。周壁部１２は、上端に近づくほど水平断面が拡大するように傾斜して延びている。 As shown in FIG. 2, the lower member 10 includes a bottom wall portion 11, a peripheral wall portion 12 extending upward from a peripheral edge portion of the bottom wall portion 11, and an upper end portion of the peripheral wall portion 12 (the side coupled to the upper member 20. ) And a lower flange portion 13 as a first fastening portion extending outward from the housing space R. The bottom wall portion 11, the peripheral wall portion 12, and the lower flange portion 13 are integrally formed using a non-conductive resin material. The bottom wall portion 11 is substantially flat and has a substantially rectangular shape in plan view. The peripheral wall portion 12 extends so as to incline so that the horizontal cross section increases as it approaches the upper end.

下側フランジ部１３は、周壁部１２の周方向に連続していて略水平方向に延びている。下側フランジ部１３には、下側部材１０と上側部材２０とを締結するための締結部材としてのボルトＢ（図１に示す）を挿入する複数の孔部１３ａが周方向に互いに間隔をあけて形成されている。孔部１３ａは上下方向に延びている。下側フランジ部１３における孔部１３ａが形成された部位は、他の部位に比べて大きく延出している。孔部１３ａには、雌ネジ部材Ｃが嵌入されている。雌ネジ部材Ｃは、ボルトＢが螺合するネジ孔を有しており、孔部１３ａの内面に固定されている。 The lower flange portion 13 is continuous in the circumferential direction of the peripheral wall portion 12 and extends in a substantially horizontal direction. In the lower flange portion 13, a plurality of holes 13a for inserting bolts B (shown in FIG. 1) as fastening members for fastening the lower member 10 and the upper member 20 are spaced apart from each other in the circumferential direction. Is formed. The hole 13a extends in the vertical direction. The site | part in which the hole 13a in the lower side flange part 13 was formed has extended largely compared with another site | part. A female screw member C is fitted into the hole 13a. The female screw member C has a screw hole into which the bolt B is screwed, and is fixed to the inner surface of the hole portion 13a.

図３に示すように、下側フランジ部１３の上面１３ｄは略水平に延びており、この上面１３ｄには、シール材Ｓが嵌まるシール溝１３ｂが形成されている。シール溝１３ｂは、下側フランジ部１３の上面１３ｄにおける孔部１３ａよりも延出方向内側に位置付けられており、下側部材１０の上方の開放部分を囲む環状溝で構成されている。シール材Ｓは、下側部材１０と上側部材２０との間をシールして主に水密性を確保するためのものであり、例えばゴム等の弾性材料で構成されている。このシール材Ｓは、シール溝１３ｂの形状に対応して環状となっている。上側フランジ部２３には、下面２３ｄにシールＳが嵌まるシール溝が形成されていてもよい。 As shown in FIG. 3, the upper surface 13d of the lower flange portion 13 extends substantially horizontally, and a seal groove 13b into which the seal material S is fitted is formed on the upper surface 13d. The seal groove 13 b is positioned on the inner side in the extending direction than the hole 13 a in the upper surface 13 d of the lower flange portion 13, and is configured by an annular groove surrounding the open portion above the lower member 10. The sealing material S is for sealing between the lower member 10 and the upper member 20 to mainly ensure water tightness, and is made of an elastic material such as rubber, for example. The sealing material S has an annular shape corresponding to the shape of the sealing groove 13b. The upper flange portion 23 may be formed with a seal groove into which the seal S is fitted on the lower surface 23d.

また、下側フランジ部１３の上面１３ｄには、シール溝１３ｂよりも延出方向内側に、段部１３ｃが形成されている。この段部１３ｃは、後述する上側部材２０の突出部２３ａが収容される収容部となっており、下側フランジ部１３の周方向に連続している。段部１３ｃの底面は略水平に延びている。また、段部１３ｃの側面１３ｓは上下方向に延びている。 Further, a step portion 13c is formed on the upper surface 13d of the lower flange portion 13 on the inner side in the extending direction than the seal groove 13b. The step portion 13 c is a housing portion that houses a protruding portion 23 a of the upper member 20 described later, and is continuous in the circumferential direction of the lower flange portion 13. The bottom surface of the step 13c extends substantially horizontally. Further, the side surface 13s of the step portion 13c extends in the vertical direction.

下側部材１０の内面には、導電体層１５が設けられている。この導電体層１５は、シート材で構成されたものである。シート材は、例えば金属が蒸着されたシート、金属繊維からなるシート、多数の細孔が形成された金属シート等のような導電性を有するシートを使用することができる。導電体層１５はシート材をインサート成形することによって得られる。すなわち、下側部材１０を成形する金型の内部にシート材を配置しておき、この状態で溶融樹脂を金型内に射出して溶融樹脂の成形と同時にシート材を成形して下側部材１０に貼り付けた状態とする。 A conductor layer 15 is provided on the inner surface of the lower member 10. The conductor layer 15 is composed of a sheet material. As the sheet material, for example, a conductive sheet such as a metal-deposited sheet, a sheet made of metal fibers, or a metal sheet having a large number of pores can be used. The conductor layer 15 is obtained by insert-molding a sheet material. That is, a sheet material is placed inside a mold for molding the lower member 10, and in this state, the molten resin is injected into the mold and the sheet material is molded simultaneously with the molding of the molten resin. 10 is attached.

尚、導電体層１５の形成方法は、インサート成形に限られるものではなく、下側部材１０の成形後に作業者がシート材を手作業で貼り付けていく、いわゆる手貼り作業による形成方法であってもよい。 Note that the method for forming the conductor layer 15 is not limited to insert molding, and is a formation method by so-called manual pasting in which an operator manually pastes the sheet material after molding the lower member 10. May be.

導電体層１５は、下側部材１０の下側フランジ部１３の段部１３ｃの側面１３ｓから底面まで連続して設けられている。 The conductor layer 15 is continuously provided from the side surface 13 s to the bottom surface of the step portion 13 c of the lower flange portion 13 of the lower member 10.

図１に示す上側部材（本発明の第１部材）２０は、電磁波遮蔽容器１の上下方向略中央部よりも上側部分を構成するものであり、下方に開放する凹状をなしている。上側部材２０は、上壁部２１と、上壁部２１の周縁部から下方へ延びる周壁部２２と、周壁部２２の下端部（下側部材１０と結合される側）から収容空間Ｒの外方へ延びる第２締結部としての上側フランジ部２３とを備えている。上壁部２１、周壁部２２及び上側フランジ部２３は、非導電性を有する樹脂材を用いて一体成形されている。上壁部２１は、略平坦で、平面視で略矩形状に形成されている。周壁部２２は、下端に近づくほど水平断面が拡大するように傾斜して延びている。 The upper member (first member of the present invention) 20 shown in FIG. 1 constitutes an upper portion of the electromagnetic shielding container 1 from the substantially vertical central portion, and has a concave shape that opens downward. The upper member 20 includes an upper wall portion 21, a peripheral wall portion 22 extending downward from the peripheral edge portion of the upper wall portion 21, and a lower end portion (side coupled to the lower member 10) of the peripheral wall portion 22. And an upper flange portion 23 as a second fastening portion extending in the direction. The upper wall portion 21, the peripheral wall portion 22, and the upper flange portion 23 are integrally formed using a non-conductive resin material. The upper wall portion 21 is substantially flat and is formed in a substantially rectangular shape in plan view. The peripheral wall portion 22 is inclined and extended so that the horizontal cross section is enlarged as it approaches the lower end.

上側フランジ部２３は、下側フランジ部１３と対応しており、周壁部２２の周方向に連続して略水平方向に延びている。上側フランジ部２３には、上記ボルトＢが挿通する複数の挿通孔（図示せず）が上記下側部材１０の孔部１３ａと一致するように形成されている。上側フランジ部２３における挿通孔が形成された部位は、下側フランジ部１３と同様に大きく延出している。 The upper flange portion 23 corresponds to the lower flange portion 13 and extends in a substantially horizontal direction continuously in the circumferential direction of the peripheral wall portion 22. A plurality of insertion holes (not shown) through which the bolts B are inserted are formed in the upper flange portion 23 so as to coincide with the hole portions 13 a of the lower member 10. The portion of the upper flange portion 23 where the insertion hole is formed extends greatly similarly to the lower flange portion 13.

図３に示すように、上側フランジ部２３の下面２３ｄは、下側フランジ部１３の上面１３ｄと略平行に延びており、この下面２３ｄの延出方向内端部には、下方へ突出する突出部２３ａが形成されている。突出部２３ａは、上側フランジ部２３の周方向に連続する突条部を構成している。この突出部２３ａの鉛直方向の断面は、略矩形状とされている。突出部２３ａにおける収容空間Ｒに臨む内側面は、周壁部２２の内面と同一面を形成するように上下方向に延びている。また、突出部２３ａにおける上記内側面とは反対側の外側側面２３ｓも上下方向に延びており、段部１３ｃの側面に沿うように形成されている。さらに、突出部２３ａの突出方向先端面は、略水平に延びており、段部１３ｃの底面に沿うように形成されている。図３（ａ）に示すように、突出部２３ａの突出高さ寸法Ｈは、段部１３ｃの深さ寸法Ｄと同じであってもよいが、変形などを考慮して、突出高さ寸法Ｈは段部１３ｃの深さ寸法Ｄよりも長く設定されている。これにより、突出部２３ａを段部１３ｃに収容して突出部２３ａの突出方向先端面を段部１３ｃの底面に接触させた状態で、突出部２３ａが段部１３ｃに完全に収容されずに、突出部２３ａの基端部が段部１３ｃから出た状態となり、下側フランジ部１３の上面１３ｄと、上側フランジ部２３の下面２３ｄとの間に所定の隙間が形成されることになる。 As shown in FIG. 3, the lower surface 23 d of the upper flange portion 23 extends substantially parallel to the upper surface 13 d of the lower flange portion 13, and protrudes downward from the inner end of the lower surface 23 d in the extending direction. A portion 23a is formed. The protrusion 23 a constitutes a protrusion that continues in the circumferential direction of the upper flange portion 23. The cross section of the protrusion 23a in the vertical direction is substantially rectangular. The inner side surface facing the accommodation space R in the projecting portion 23 a extends in the vertical direction so as to form the same surface as the inner surface of the peripheral wall portion 22. Further, the outer side surface 23s opposite to the inner side surface in the protruding portion 23a also extends in the vertical direction, and is formed along the side surface of the step portion 13c. Furthermore, the protrusion direction front end surface of the protrusion 23a extends substantially horizontally and is formed along the bottom surface of the step 13c. As shown in FIG. 3A, the protruding height dimension H of the protruding portion 23a may be the same as the depth dimension D of the stepped portion 13c. Is set longer than the depth dimension D of the stepped portion 13c. Thereby, in a state where the protruding portion 23a is accommodated in the stepped portion 13c and the front end surface of the protruding portion 23a is brought into contact with the bottom surface of the stepped portion 13c, the protruding portion 23a is not completely accommodated in the stepped portion 13c. The base end portion of the protruding portion 23 a comes out of the step portion 13 c, and a predetermined gap is formed between the upper surface 13 d of the lower flange portion 13 and the lower surface 23 d of the upper flange portion 23.

上側フランジ部２３の下面２３ｄにおいて突出部２３ａが形成された部分以外は、略平坦に形成されている。この平坦な部分にシール材Ｓが接触するようになっている。 Except for the portion where the protruding portion 23a is formed on the lower surface 23d of the upper flange portion 23, the upper flange portion 23 is formed substantially flat. The sealing material S comes into contact with this flat portion.

上側部材２０の内面には、導電体層２５が設けられている。この導電体層２５は、下側部材１０の導電体層１５と同様なシート材で構成されたものである。 A conductor layer 25 is provided on the inner surface of the upper member 20. The conductor layer 25 is made of a sheet material similar to the conductor layer 15 of the lower member 10.

導電体層２５は、上側部材２０の上側フランジ部２３の突出部２３ａの内側面から突出方向先端面２３ｔ、外側側面２３ｓまで連続して設けられている。 The conductor layer 25 is continuously provided from the inner side surface of the protruding portion 23a of the upper flange portion 23 of the upper member 20 to the distal end surface 23t in the protruding direction and the outer side surface 23s.

次に、上記のように構成された電磁波遮蔽容器１に物品を収容する場合について説明する。下側部材１０に例えば電気自動車の走行用バッテリーを収容した後、そのバッテリーを上方から覆うように上側部材２０をバッテリーにかぶせる。そして、上側部材２０の上側フランジ部２３と、下側部材１０の下側フランジ部１３とを合わせるようにして、上側フランジ部２３の突出部２３ａを下側フランジ部１３の段部１３ｃに嵌めて収容した状態とする。この状態で、突出部２３ａの先端面２３ｔを覆う導電体層２５と、段部１３ｃの底面を覆う導電体層１５とが接触するとともに、突出部２３ａの外側側面２３ｓを覆う導電体層２５と、段部１３ｃの側面１３ｓを覆う導電体層１５とが接触するか又は若干の隙間を形成して隣接する。 Next, a case where an article is stored in the electromagnetic shielding container 1 configured as described above will be described. For example, after a battery for running an electric vehicle is accommodated in the lower member 10, the upper member 20 is placed on the battery so as to cover the battery from above. Then, the upper flange portion 23 of the upper member 20 and the lower flange portion 13 of the lower member 10 are matched with each other, and the protruding portion 23a of the upper flange portion 23 is fitted into the step portion 13c of the lower flange portion 13. Keep it in a housed state. In this state, the conductor layer 25 covering the tip end surface 23t of the protrusion 23a and the conductor layer 15 covering the bottom surface of the stepped portion 13c are in contact with each other, and the conductor layer 25 covering the outer side surface 23s of the protrusion 23a The conductor layer 15 covering the side surface 13s of the step portion 13c comes into contact with each other or forms a slight gap.

そして、ボルトＢを上側部材２０の上側フランジ部２３の挿通孔に挿通して下側部材１０の下側フランジ部１３の雌ネジ部材Ｃに螺合させ、上側フランジ部２３と下側フランジ部１３とを締結する。このとき、突出部２３ａの突出高さ寸法Ｈを、段部１３ｃの深さ寸法Ｄよりも長く設定して下側フランジ部１３の上面１３ｄと上側フランジ部２３の下面２３ｄとの間に所定の隙間を形成するようにしているので、突出部２３ａの先端面２３ｔを覆う導電体層２５と、段部１３ｃの底面を覆う導電体層１５とをボルトＢの締結力によって強く接触させることができる。突出部２３ａと段部１３ｃが接触していれば、隙間が若干開いているだけでもよい。 Then, the bolt B is inserted into the insertion hole of the upper flange portion 23 of the upper member 20 and screwed into the female screw member C of the lower flange portion 13 of the lower member 10, so that the upper flange portion 23 and the lower flange portion 13 are engaged. And conclude. At this time, the protruding height dimension H of the protruding portion 23a is set longer than the depth dimension D of the stepped portion 13c, and a predetermined height is provided between the upper surface 13d of the lower flange portion 13 and the lower surface 23d of the upper flange portion 23. Since the gap is formed, the conductor layer 25 covering the tip end surface 23t of the protruding portion 23a and the conductor layer 15 covering the bottom surface of the stepped portion 13c can be strongly contacted by the fastening force of the bolt B. . As long as the protrusion 23a and the step 13c are in contact with each other, the gap may be slightly opened.

下側部材１０及び上側部材２０を樹脂製にすると、熱変形や経年変化、物品の重量等によって下側部材１０と上側部材２０との間に隙間が形成される恐れがあるが、この実施形態では、下側フランジ部１３と上側フランジ部２３とを複数箇所で締結することで、下側フランジ部１３と上側フランジ部２３との開きが抑制される。その結果、突出部２３ａの先端面２３ｔを覆う導電体層２５と、段部１３ｃの底面を覆う導電体層１５とが離れるのを防止することができる。 If the lower member 10 and the upper member 20 are made of resin, a gap may be formed between the lower member 10 and the upper member 20 due to thermal deformation, aging, the weight of the article, and the like. Then, the opening of the lower flange portion 13 and the upper flange portion 23 is suppressed by fastening the lower flange portion 13 and the upper flange portion 23 at a plurality of locations. As a result, it is possible to prevent the conductor layer 25 covering the tip end surface 23t of the protruding portion 23a from separating from the conductor layer 15 covering the bottom surface of the stepped portion 13c.

以上説明したように、この実施形態に係る電磁波遮蔽容器１によれば、下側部材１０の下側フランジ部１３と、上側部材２０の上側フランジ部２３とをボルトＢにより締結し、下側部材１０の導電体層１５と上側部材２０の導電体層２５とを接触させるようにしたので、電磁波の遮蔽性を良好に維持することができる。 As explained above, according to the electromagnetic wave shielding container 1 according to this embodiment, the lower flange portion 13 of the lower member 10 and the upper flange portion 23 of the upper member 20 are fastened by the bolt B, and the lower member Since the ten conductor layers 15 and the conductor layer 25 of the upper member 20 are brought into contact with each other, the electromagnetic wave shielding property can be maintained well.

また、上側部材２０の上側フランジ部２３に突出部２３ａを形成し、この突出部２３ａの外側側面２３ｓから先端面２３ｔまで連続するように導電体層２５を内周面に設けたので、電磁波の遮蔽性をさらに良好にできる。 Further, since the protrusion 23a is formed on the upper flange portion 23 of the upper member 20, and the conductor layer 25 is provided on the inner peripheral surface so as to continue from the outer side surface 23s to the tip surface 23t of the protrusion 23a, The shielding property can be further improved.

また、下側部材１０の下側フランジ部１３に、上側部材２０の突出部２３ａを収容するための段部１３ｃを形成し、この段部１３ｃの側面１３ｓから底面まで連続するように導電体層１５を内周面に設けたので、電磁波の遮蔽性をさらに良好にできる。 In addition, a step portion 13c for accommodating the protruding portion 23a of the upper member 20 is formed on the lower flange portion 13 of the lower member 10, and the conductor layer is continuous from the side surface 13s to the bottom surface of the step portion 13c. Since 15 is provided on the inner peripheral surface, the electromagnetic wave shielding property can be further improved.

また、図４に示す変形例１のように、下側部材１０の下側フランジ部１３の段部１３ｃの底面に溝部１３ｅを設けてもよい。溝部１３ｅは下側フランジ部１３の全周に亘って連続している。溝部１３ｅの内面には、導電体層１５が設けられている。下側フランジ部１３の下面には、溝部１３ｅの形成により、膨出部１３ｆが形成されている。変形例１の上側部材２０の上側フランジ部２３の下面２３ｄには、溝部２３ｅが形成されている。溝部２３ｅは上側フランジ部２３の全周に亘って連続している。溝部２３ｅは、突出部２３ａよりも上側フランジ部２３の延出方向外側に位置しており、突出部２３ａと溝部２３ｅとは上側フランジ部２３の延出方向に隣接している。また、上側フランジ部２３の上面には、溝部２３ｅの形成により、膨出部２３ｆが形成されている。 Moreover, you may provide the groove part 13e in the bottom face of the step part 13c of the lower side flange part 13 of the lower side member 10 like the modification 1 shown in FIG. The groove portion 13e is continuous over the entire circumference of the lower flange portion 13. A conductor layer 15 is provided on the inner surface of the groove 13e. A bulging portion 13 f is formed on the lower surface of the lower flange portion 13 by forming a groove portion 13 e. A groove portion 23e is formed on the lower surface 23d of the upper flange portion 23 of the upper member 20 of the first modification. The groove 23 e is continuous over the entire circumference of the upper flange portion 23. The groove part 23e is located on the outer side in the extending direction of the upper flange part 23 relative to the protruding part 23a, and the protruding part 23a and the groove part 23e are adjacent to each other in the extending direction of the upper flange part 23. Further, a bulging portion 23f is formed on the upper surface of the upper flange portion 23 by forming the groove portion 23e.

溝部１３ｅ、２３ｅを設けることによって、導電体層１５、２５を手作業で貼る時に、導電体層１５、２５の端末部分を溝部１３ｅ、２３ｅに挿入することによってはがれにくくすることができるし、端末処理作業が容易になる。 By providing the groove portions 13e and 23e, when the conductor layers 15 and 25 are pasted manually, the terminal portions of the conductor layers 15 and 25 can be made difficult to peel off by inserting them into the groove portions 13e and 23e. Processing work becomes easy.

また、図５に示す変形例２のように、上側部材２０の上側フランジ部２３の下面２３ｄにおける延出方向中間部に突出部２３ｇを設けてもよい。突出部２３ｇは、上側フランジ部２３の周方向に連続している。導電体層２５は、突出部２３ｇの側面から突出方向先端面２３ｔまで設けられている。下面２３ｄにおける突出部２３ｇの形成部分よりも上側フランジ部２３の延出方向内側は、水平方向に延びる平坦面２３ｈで構成されている。導電体層２５は、平坦面２３ｈにも設けられている。 Further, as in Modification 2 shown in FIG. 5, a protruding portion 23 g may be provided at the intermediate portion in the extending direction on the lower surface 23 d of the upper flange portion 23 of the upper member 20. The protruding portion 23g is continuous in the circumferential direction of the upper flange portion 23. The conductor layer 25 is provided from the side surface of the protrusion 23g to the front end surface 23t in the protrusion direction. The inner side in the extending direction of the upper flange portion 23 is formed by a flat surface 23h extending in the horizontal direction with respect to the formation portion of the protruding portion 23g on the lower surface 23d. The conductor layer 25 is also provided on the flat surface 23h.

また、変形例２の下側部材１０の下側フランジ部１３の上面１３ｄには、上記突出部２３ｇが収容される収容部としての凹部１３ｇが形成されている。導電体層１５は、凹部１３ｇの側面から底面まで設けられている。上面１３ｄにおける凹部１３ｇの形成部分よりも下側フランジ部１３の延出方向内側は、水平方向に延びる平坦面１３ｈで構成されている。導電体層１５は、平坦面１３ｈにも設けられている。 In addition, a concave portion 13g is formed on the upper surface 13d of the lower flange portion 13 of the lower member 10 of the modified example 2 as an accommodating portion for accommodating the protruding portion 23g. The conductor layer 15 is provided from the side surface to the bottom surface of the recess 13g. The inner side in the extending direction of the lower flange portion 13 than the portion where the concave portion 13g is formed on the upper surface 13d is constituted by a flat surface 13h extending in the horizontal direction. The conductor layer 15 is also provided on the flat surface 13h.

図５（ｂ）に示すように、下側部材１０と上側部材２０とを結合した状態で、突出部２３ｇが凹部１３ｇに嵌まって収容された状態となる。さらに、突出部２３ｇを覆う導電体層２５と凹部１３ｇを覆う導電体層１５とが接触するとともに、平坦面２３ｈを覆う導電体層２５と平坦面１３ｈを覆う導電体層１５とが接触する。 As shown in FIG. 5B, in a state in which the lower member 10 and the upper member 20 are coupled, the protruding portion 23g is fitted and accommodated in the concave portion 13g. Furthermore, the conductor layer 25 covering the protruding portion 23g and the conductor layer 15 covering the recess 13g are in contact with each other, and the conductor layer 25 covering the flat surface 23h and the conductor layer 15 covering the flat surface 13h are in contact with each other.

図６に示す変形例３のように、下側部材１０の下側フランジ部１３の上面１３ｄに、凹部１３ｉ及び凸部１３ｊを設けてもよい。凹部１３ｉは、段部１３ｃよりも下側フランジ部１３の延出方向外側に位置づけられている。導電体層１５は、凹部１３ｉの内面にも設けられている。 As in Modification 3 shown in FIG. 6, the concave portion 13 i and the convex portion 13 j may be provided on the upper surface 13 d of the lower flange portion 13 of the lower member 10. The recessed portion 13i is positioned on the outer side in the extending direction of the lower flange portion 13 with respect to the step portion 13c. The conductor layer 15 is also provided on the inner surface of the recess 13i.

変形例３の上側部材２０の上側フランジ部２３には、凹部１３ｉに収容される凸部２３ｉが設けられるとともに、凸部１３ｊが収容される凹部２３ｊが設けられている。導電体層２５は、凸部２３ｉの外面にも設けられている。 The upper flange portion 23 of the upper member 20 of Modification 3 is provided with a convex portion 23i that is accommodated in the concave portion 13i and a concave portion 23j that accommodates the convex portion 13j.

図６（ｂ）に示すように、下側部材１０と上側部材２０とを結合した状態で、凸部２３ｉが凹部１３ｉに嵌まって収容された状態となる。 As shown in FIG. 6B, in a state where the lower member 10 and the upper member 20 are coupled, the convex portion 23i is fitted into the concave portion 13i and accommodated.

また、図７に示す変形例４は、上記変形例１で示した形状の下側部材１０の下側フランジ部１３に、インサート部材５０をインサート成形するようにしてもよい。インサート部材５０は、複数用いられて導電体層２５となるシート材Tを成形時の金型内で所定位置に断続的に保持するための保持部材である。すなわち、図８（ａ）に示すように、下側部材１０を成形する金型として、第１型１００及び第２型１０１を用意する。第２型１０１には、インサート部材５０を挿入保持するための保持孔１０１ａを形成する。また、第１型１００には、溝部１３ｅを成形するための凸部１００ａを形成する。導電体層１５となるシート材Ｔは、キャビティ内に配置し、また、インサート部材５０は、保持孔１０１ａに保持しておく。この状態で、シート材Ｔをインサート部材５０と凸部１００ａとで挟んでおく。そして、図８（ｂ）に示すように溶融樹脂材Ａをキャビティに射出すると、シート材Ｔが樹脂の流動圧によって押されて第１型１００の内面に沿うように変形して成形されるとともに、樹脂材と一体化する。シート材Ｔが第１型１００の内面に沿うように変形する際、シート材Ｔは、インサート部材５０と凸部１００ａとの間を滑るようにして移動していくので、段部１３ｃに樹脂材が射出圧によって圧入され、更にフランジ部端末に圧入される。よって、成形性が悪化することはない。 In the fourth modification shown in FIG. 7, the insert member 50 may be insert-molded in the lower flange portion 13 of the lower member 10 having the shape shown in the first modification. The insert member 50 is a holding member for intermittently holding the sheet material T used as a conductor layer 25 in a predetermined position in a mold during molding. That is, as shown in FIG. 8A, a first mold 100 and a second mold 101 are prepared as molds for molding the lower member 10. A holding hole 101a for inserting and holding the insert member 50 is formed in the second mold 101. Further, the first mold 100 is provided with a convex portion 100a for forming the groove portion 13e. The sheet material T to be the conductor layer 15 is disposed in the cavity, and the insert member 50 is held in the holding hole 101a. In this state, the sheet material T is sandwiched between the insert member 50 and the convex portion 100a. When the molten resin material A is injected into the cavity as shown in FIG. 8B, the sheet material T is pressed by the flow pressure of the resin and deformed along the inner surface of the first mold 100 and molded. Integrate with resin material. When the sheet material T is deformed so as to be along the inner surface of the first mold 100, the sheet material T moves so as to slide between the insert member 50 and the convex portion 100a. Is press-fitted by the injection pressure, and is further press-fitted into the flange end. Therefore, the moldability does not deteriorate.

また、変形例４では、上側部材２０の上側フランジ部２３に、インサート部材４０をインサート成形している。インサート部材４０は、導電体層１５となるシート材を金型内で所定位置に保持するための保持部材である。すなわち、図９（ａ）に示すように、上側部材２０を成形する金型として、第１型１０２及び第２型１０３を用意する。第１型１０２には、インサート部材４０を挿入保持するための保持孔１０２ａを形成する。また、第２型１０３には、溝部２３ｅを成形するための凸部１０３ａを形成する。導電体層２５となるシート材Ｔは、キャビティ内に配置し、また、インサート部材４０は、保持孔１０２ａに保持しておく。この状態で、シート材Ｔをインサート部材４０と凸部１０３ａとで挟んでおく。そして、図９（ｂ）に示すように溶融樹脂材Ａをキャビティに射出すると、シート材Ｔが樹脂の流動圧によって押されて第２型１０３の内面に沿うように変形して成形されるとともに、樹脂材と一体化する。シート材Ｔが第１型１０３の内面に沿うように変形する際、シート材Ｔは、インサート部材４０と凸部１０３ａとの間を滑るようにして移動していくので、成形性が悪化することはない。 In the fourth modification, the insert member 40 is insert-molded in the upper flange portion 23 of the upper member 20. The insert member 40 is a holding member for holding the sheet material to be the conductor layer 15 in a predetermined position in the mold. That is, as shown in FIG. 9A, a first mold 102 and a second mold 103 are prepared as molds for molding the upper member 20. In the first mold 102, a holding hole 102a for inserting and holding the insert member 40 is formed. Further, the second mold 103 is provided with a convex portion 103a for forming the groove portion 23e. The sheet material T to be the conductor layer 25 is disposed in the cavity, and the insert member 40 is held in the holding hole 102a. In this state, the sheet material T is sandwiched between the insert member 40 and the convex portion 103a. When the molten resin material A is injected into the cavity as shown in FIG. 9B, the sheet material T is pressed by the flow pressure of the resin and deformed along the inner surface of the second mold 103 and molded. Integrate with resin material. When the sheet material T is deformed along the inner surface of the first mold 103, the sheet material T moves so as to slide between the insert member 40 and the convex portion 103a, so that the formability is deteriorated. There is no.

各々のシート材Ｔは、上側フランジ部２３の下面２３ｄと下側フランジ部１３の上面１３ｄのシール材Ｓが設けられる部分に貼り付けないようにする必要がある。その理由は、シール材Ｓを嵌める溝部１３ｂの底面にシート材Ｔが挟まっていたり、シール材Ｓの上側端部が当接する上側フランジ部２３の下面２３ｄにシート材Ｔが貼り付けられていると、シール性を保証できなくなる恐れがあるからである。 Each sheet material T needs to be not attached to a portion where the seal material S is provided on the lower surface 23 d of the upper flange portion 23 and the upper surface 13 d of the lower flange portion 13. The reason is that the sheet material T is sandwiched on the bottom surface of the groove 13b into which the seal material S is fitted, or the sheet material T is attached to the lower surface 23d of the upper flange portion 23 with which the upper end of the seal material S abuts. This is because the sealing performance may not be guaranteed.

その対策として、シート材Ｔをインサート成形する場合、インサート部材４０，５０を用いてシート材Ｔの端末近傍を金型と共に挟むことによって、シート材Ｔが捲れ上がることを防止でき、かつ、突出部２３ａの突出方向先端面２３ｔと段部１３ｃの底面とが確実に覆われるようになるので、突出部２３ａの先端面２３ｔを覆うシート材Ｔ（導電体層２５）と、段部１３ｃの底面を覆うシート材Ｔ（導電体層１５）とを接触させることができるようになり、確実に電磁波シールドできる。 As a countermeasure, when the sheet material T is insert-molded, the sheet material T can be prevented from rolling up by sandwiching the vicinity of the end of the sheet material T with the mold using the insert members 40 and 50, and the protruding portion. Since the front end surface 23t in the protruding direction of 23a and the bottom surface of the stepped portion 13c are reliably covered, the sheet material T (conductor layer 25) covering the front end surface 23t of the protruding portion 23a and the bottom surface of the stepped portion 13c are covered. The covering sheet material T (conductor layer 15) can be brought into contact with each other, and the electromagnetic wave can be reliably shielded.

An insert member 50 similar to that of the modified example 4 may be insert-molded in the side flange portion 13.

また、図１１に示す変形例６のように、下側部材１０を、導電性を有する金属材料で構成してもよい。この場合、上側部材２０の上側フランジ部２３にシール材Ｓを挿入する溝２３ｋを形成する。図１１（ｂ）に示すように、下側部材１０と上側部材２０とを結合した状態で、突出部２３ｃを覆う導電体層２５と、下側部材１０の導電性を有する部分とが接触する。また、下側部材１０と上側部材２０とはボルト（図示せず）で締結する。 Moreover, you may comprise the lower member 10 with the metal material which has electroconductivity like the modification 6 shown in FIG. In this case, a groove 23 k into which the sealing material S is inserted is formed in the upper flange portion 23 of the upper member 20. As shown in FIG. 11B, in a state where the lower member 10 and the upper member 20 are coupled, the conductor layer 25 covering the protruding portion 23c and the conductive portion of the lower member 10 are in contact with each other. . The lower member 10 and the upper member 20 are fastened with bolts (not shown).

Further, the conductor layer 25 of the upper member 20 may be provided on the outer surface of the upper member 20.
