Description

本発明は、携帯電話などの内部に設けられる基板に取り付けて、基板の回路から発する電磁波を外部に漏洩することを防止し、また、外部からの妨害波が入り込むことを防止することができるシールドケース及び電磁波のシールド構造に関するものである。   The present invention is a shield that can be attached to a substrate provided inside a cellular phone or the like to prevent electromagnetic waves emitted from the circuit of the substrate from leaking to the outside, and to prevent interference waves from entering from the outside. The present invention relates to a case and an electromagnetic wave shielding structure.

電子機器に内蔵された高周波回路には、この高周波回路から電磁波が外部に漏れると他の機器への悪影響のおそれがあり、また、外部の機器などから発生した電磁波によって、回路へ悪影響のおそれがある。このため、従来より、このような高周波回路と外部との間にシールドケースを設けて、基板の回路から発する電磁波を外部に漏洩することを防止し、また、外部からの妨害波が入り込むことを防止している。   The high-frequency circuit built in the electronic device may have an adverse effect on other devices if electromagnetic waves leak from the high-frequency circuit. Also, the electromagnetic wave generated from an external device may adversely affect the circuit. is there. For this reason, conventionally, a shield case is provided between such a high-frequency circuit and the outside to prevent leakage of electromagnetic waves emitted from the circuit of the board to the outside, and interference waves from the outside can enter. It is preventing.

特許文献１には、シールドケースを用いた電磁波のシールド構造が開示されている。この電磁波のシールド構造のシールドケースは、本体部材とカバー部材から構成されている。そして、シールドケースは、天面と４つの側面とによって高周波回路を覆い、電磁波をシールドしている。
特許文献１の本体部材及びカバー部材はいずれも金属製であり、高周波回路を本体部材で囲んだ状態で高周波回路が設けられた基板などに固定し、カバー部材を本体部材に嵌め込んで、高周波回路をカバー部材によって覆っている。 Patent Document 1 discloses an electromagnetic wave shield structure using a shield case. The shield case having the electromagnetic wave shield structure includes a main body member and a cover member. The shield case covers the high frequency circuit with the top surface and the four side surfaces to shield the electromagnetic waves.
The main body member and the cover member of Patent Document 1 are both made of metal, fixed to a substrate or the like on which the high-frequency circuit is provided in a state where the high-frequency circuit is surrounded by the main body member, and the cover member is fitted into the main body member. The circuit is covered with a cover member.

そして、カバー部材を本体部材を着脱するようにしておき、使用時にはカバー部材を嵌めて電磁波のシールドを行うようにし、また、カバー部材を外して内部の高周波回路の点検・確認などを行うことができる。特許文献１には、カバー部材に本体部材に向かって押圧するように係合片を設け、カバー部材の両側から本体部材を挟むような構造や、本体部材に突起などにカバー部材の係合片を引っかけるような構造が記載されている。
特開昭５９−１５８５９４号公報 In addition, the cover member is attached to and detached from the main body member, and when used, the cover member is fitted to shield electromagnetic waves, and the cover member is removed to check and confirm the internal high-frequency circuit. it can. In Patent Document 1, an engagement piece is provided on the cover member so as to be pressed toward the main body member, and the main body member is sandwiched from both sides of the cover member, or the engagement piece of the cover member is provided on a protrusion on the main body member. A structure that hooks is described.
JP 59-158594 A

一方、シールドケースを基板上に位置決めして取り付けるには、基板に孔を設け、シールドケースに設けられた突起などを挿入して固定する方法と、シールドケースをそのまま位置決めしてはんだ付けなどで固定する方法（表面実装）がある。しかしながら、基板に孔を設けて突起を挿入して固定する方法は、基板強度の低下や、配線密度の低下（穴を空ける場所やそのための間隔を確保のため）などの問題があるので、表面実装が望ましい。   On the other hand, in order to position and attach the shield case on the board, a hole is made in the board, and a protrusion provided on the shield case is inserted and fixed, and the shield case is positioned and fixed by soldering etc. There is a method (surface mounting). However, the method of fixing holes by providing holes in the substrate has problems such as a decrease in substrate strength and a decrease in wiring density (to secure a place to make holes and a space for the holes). Implementation is desirable.

近年、高周波回路が高機能化し、薄いものや小さいものが使用されるようになっている。しかしながら、特許文献１に記載のシールド構造のように、カバー部材の両側面部を本体部材に対して挟んで使用時に固定するような構造では、カバー部材の側面部の長さ（高周波回路の厚み方向の長さ）がある程度長くないと、側面部の弾性範囲の揺動による変形量が小さいので、十分な固定力が得られない。そのため、固定力を得るために側面部の長さを長くしなければならず、高周波回路の厚みよりも厚み方向に長いシールドケースを用いなくてはならなかった。
そのため、薄い高周波回路を用いても、カバー部材の厚みが大きくなるので、電子機器の薄型化、小型化を行うことができなかった。 In recent years, high-frequency circuits have become highly functional, and thin and small ones have been used. However, as in the shield structure described in Patent Document 1, the length of the side surface of the cover member (in the thickness direction of the high-frequency circuit) is fixed in use by sandwiching both side surfaces of the cover member with respect to the main body member. If the length is not long to some extent, the amount of deformation due to the swinging of the elastic range of the side surface portion is small, so that a sufficient fixing force cannot be obtained. Therefore, in order to obtain a fixing force, the length of the side surface portion must be increased, and a shield case that is longer in the thickness direction than the thickness of the high-frequency circuit must be used.
For this reason, even if a thin high-frequency circuit is used, the thickness of the cover member increases, so that the electronic device cannot be reduced in thickness and size.

また、図１０に示されるシールドケース１００のように、本体部材１０２とカバー部材１０３とに内側に凹んだ変形部１０４、１０５を設け、変形部１０４、１０５によって本体部材１０２とカバー部材１０３とを着脱可能に固定する構造が考えられる。   Further, like the shield case 100 shown in FIG. 10, the main body member 102 and the cover member 103 are provided with deformed portions 104 and 105 that are recessed inwardly, and the main body member 102 and the cover member 103 are connected by the deformable portions 104 and 105. A structure that can be detachably fixed is conceivable.

本体部材１０２を基板に表面実装する際には、本体部材１０２を移動して位置決めすることが必要であり、そのため、天面側の中央付近に吸着部１０６を設けている。
吸着部１０６は所定の面積を有し、ほぼ平面状である。そして、表面実装を行う装置に設けられた吸引装置を吸着部１０６に近づけて、吸引装置を操作することにより、本体部材１０２の移動、位置決めを行っている。このような吸着部１０６は、シールドケース１００が小さいなどの場合、掴む方法などの他の方法で移動等が行いにくい際には必ず設けられるものである。 When the main body member 102 is surface-mounted on the substrate, it is necessary to move and position the main body member 102. For this reason, the suction portion 106 is provided near the center on the top surface side.
The adsorption part 106 has a predetermined area and is substantially planar. Then, the main body member 102 is moved and positioned by operating the suction device by bringing the suction device provided in the surface mounting device closer to the suction unit 106. Such a suction portion 106 is always provided when the shield case 100 is small or the like, and when it is difficult to move by other methods such as a gripping method.

吸着部１０６は所定の大きさの平面が必要なため天面側に設けることになる。そのため、カバー部材１０３を本体部材１０２に取り付けた場合には、カバー部材１０３の天面部１１３と吸着部１０６とが重なり、内部の空間を同じにする場合には、シールドケース１００の厚みが増してしまう。また、吸着部１０６を避けるように内部の高周波回路の配置を変更するのは、内部の回路設計が煩雑となってしまう。
そのため、内部の空間に対してシールドケース１００の厚みが大きくなってしまうので、電子機器の薄型化、小型化を行うことができなかった。 The suction unit 106 is provided on the top surface side because a plane having a predetermined size is required. Therefore, when the cover member 103 is attached to the main body member 102, the top surface portion 113 of the cover member 103 and the suction portion 106 overlap, and when the internal space is made the same, the thickness of the shield case 100 increases. End up. Further, changing the arrangement of the internal high-frequency circuit so as to avoid the suction unit 106 makes the internal circuit design complicated.
Therefore, since the thickness of the shield case 100 is increased with respect to the internal space, the electronic device cannot be reduced in thickness and size.

さらに、基板などに取り付けた後に、シールドケース１００内を確認する際に、一旦カバー部材１０３を外すことになる。そして、再び使用する際には、再び取り付けなければならないが、シールドケース１００が小さい場合などには、一旦外されたカバー部材１０３を本体部材１０２に位置決めする作業が難しかった。   Furthermore, when the inside of the shield case 100 is confirmed after being attached to a substrate or the like, the cover member 103 is once removed. When the shield case 100 is small, it is difficult to position the cover member 103 once removed on the main body member 102 when the shield case 100 is small.

そこで、本発明は、薄型の高周波回路などの場合にも、その厚みに対して対応することが可能であり、基板などに取り付け後もカバー部材を取り外して点検等を行うことが容易である電磁波のシールド構造を提供することを課題とする。   Therefore, the present invention can cope with the thickness even in the case of a thin high-frequency circuit and the like. It is an object to provide a shield structure.

側面部２１と側面部２３は幅方向に対向し、側面部２２と側面部２４は長さ方向に対向している。４つの側面部２１、２２、２３、２４の厚み方向の長さは等しく、底面側の辺は同一平面上に位置している。そして、天面部２５に対向する底面側は金属板が設けられず開口２７となっており、この開口２７を形成する縁は所定の平面を形成し、開口２７全体を平面に対して密着させることができる。 As shown in FIG. 3, the main body member 12 is a rectangular parallelepiped member provided with a top surface portion 25 having four side surface portions 21, 22, 23, 24 and an opening portion 25 a and having an internal space 26 inside. .
The side surface portion 21 and the side surface portion 23 face each other in the width direction, and the side surface portion 22 and the side surface portion 24 face each other in the length direction. The lengths in the thickness direction of the four side portions 21, 22, 23, 24 are equal, and the sides on the bottom surface side are located on the same plane.

軸保持部材２８、２９の底面側には折部２８ａ、２９ａが設けられており、折部２８ａ、２９ａで側面部２１とつながっている。 Shaft holding members 28 and 29 are provided outside the side surface portion 21. A shaft portion 30 of the cover member 13 to be described later is inserted and held between the shaft holding members 28 and 29 and the side surface portion 21.
Folded portions 28a and 29a are provided on the bottom surfaces of the shaft holding members 28 and 29, and are connected to the side surface portion 21 by the folded portions 28a and 29a.

軸保持部材２８、２９の天面側の端部２８ｃ、２９ｃは、外側に向かって傾斜し、また、側面部２１から離れる方向に向かって弾性変形して移動することができる。そして、軸保持部材２８、２９の厚み方向の中間部付近には突出部２８ｂ、２９ｂが設けられて、突出部２８ｂ、２９ｂの内側と側面部２１との間に軸部３０を保持する空間が形成される。   End portions 28c and 29c on the top surface side of the shaft holding members 28 and 29 are inclined toward the outside, and can be moved while being elastically deformed in a direction away from the side surface portion 21. Protrusions 28 b and 29 b are provided in the vicinity of the intermediate portions in the thickness direction of the shaft holding members 28 and 29, and a space for holding the shaft portion 30 is provided between the inside of the protrusions 28 b and 29 b and the side surface portion 21. It is formed.

したがって、天面側からカバー部材１３の軸部３０を挿入して突出部２８ｂ、２９ｂ付近で保持することができ、また、軸部３０を挿入した後には、弾性回復により軸保持部材２８、２９の天面側が戻る。
そして、図５に示されるように、軸保持部材２８、２９と側面部２１とによって、軸部３０を囲むような状態となる。 Therefore, the shaft portion 30 of the cover member 13 can be inserted from the top surface side and can be held in the vicinity of the protruding portions 28b and 29b. After the shaft portion 30 is inserted, the shaft holding members 28 and 29 are recovered by elastic recovery. The top side of will return.
As shown in FIG. 5, the shaft holding member 28, 29 and the side surface portion 21 surround the shaft portion 30.

図３に示されるように、側面部２２、２３、２４には各３カ所の本体側変形部４５が設けられている。本体側変形部４５は外側から見ると凹んでおり内側には突出している円状に変形した部分である。   As shown in FIG. 3, three main body side deformation portions 45 are provided on the side surface portions 22, 23, and 24, respectively. The main body side deforming portion 45 is a circularly deformed portion that is recessed when viewed from the outside and protrudes inside.

カバー部材１３は、図３に示されるように、４つの側面部３１、３２、３３、３４と天面部３５が設けられ、内部に内部空間３６を有している。側面部３１と側面部３３は幅方向に対向し、側面部３２と側面部３４は長さ方向に対向している。４つの側面部３１、３２、３３、３４の厚み方向の長さは、本体部材１２の４つの側面部２１、２２、２３、２４と比較して、やや短くなっている。
また、天面部２５に対向する底面側は金属板が設けられず開口３７となっている。 As shown in FIG. 3, the cover member 13 includes four side surfaces 31, 32, 33, 34 and a top surface 35, and has an internal space 36 inside. The side surface portion 31 and the side surface portion 33 face each other in the width direction, and the side surface portion 32 and the side surface portion 34 face each other in the length direction. The lengths of the four side surfaces 31, 32, 33, 34 in the thickness direction are slightly shorter than the four side surfaces 21, 22, 23, 24 of the main body member 12.
Further, the bottom surface side facing the top surface portion 25 is not provided with a metal plate and has an opening 37.

カバー部材１３は本体部材１２よりもやや大きく、具体的にはカバー部材１３の形成に使用される金属板の厚みの分程度大きい。したがって、カバー部材１３の内側の大きさと、本体部材１２の外形の大きさとがほぼ同じであり、カバー部材１３は本体部材１２の外側をほぼ密着した状態で覆うことができる。   The cover member 13 is slightly larger than the main body member 12, and specifically, is approximately as large as the thickness of the metal plate used to form the cover member 13. Therefore, the size of the inside of the cover member 13 and the size of the outer shape of the main body member 12 are substantially the same, and the cover member 13 can cover the outer side of the main body member 12 in a substantially intimate contact state.

側面部３１には、軸部３０及び貫通孔３８、３９が設けられている。
軸部３０は、側面部３１の底面側の端部付近の折部５６が外側に折り返されて形成されたものであり、側面部３１の底面側に配置されている。軸部３０は折り返して形成されるので、この厚みは金属板の厚みの約２倍であり、折り返しの長さはこの厚みに近い長さである。したがって、軸部３０の形状は、幅方向に直線状に延びる棒状であって、側面部３１の幅と同じ長さであって側面部３１の端部に全域に設けられている。また、軸部３０の断面の縦横の長さはほぼ等しい。
貫通孔３８、３９は、本体部材１２の軸保持部材２８、２９の端部２８ｃ、２９ｃに対応する付近に設けられている。また、貫通孔３８、３９の幅は軸保持部材２８、２９の端部２８ｃ、２９ｃの幅よりやや大きい。 The side surface portion 31 is provided with a shaft portion 30 and through holes 38 and 39.
The shaft portion 30 is formed by folding a folding portion 56 in the vicinity of the end portion of the side surface portion 31 on the bottom surface side, and is disposed on the bottom surface side of the side surface portion 31. Since the shaft portion 30 is formed by folding, the thickness is about twice the thickness of the metal plate, and the length of the folding is close to this thickness. Therefore, the shape of the shaft portion 30 is a rod shape that extends linearly in the width direction, has the same length as the width of the side surface portion 31, and is provided in the entire end portion of the side surface portion 31. Moreover, the length of the cross section of the axial part 30 is substantially equal.
The through holes 38 and 39 are provided in the vicinity corresponding to the end portions 28 c and 29 c of the shaft holding members 28 and 29 of the main body member 12. Further, the widths of the through holes 38 and 39 are slightly larger than the widths of the end portions 28 c and 29 c of the shaft holding members 28 and 29.

図３に示されるように、側面部３２、３３、３４に各３カ所のカバー側変形部５５が設けられている。カバー側変形部５５は外側から見ると凹んでおり内側には突出している円状に変形した部分であって、本体部材１２の本体側変形部４５とほぼ同様の形状である。また、カバー側変形部５５の位置は本体部材１２の本体側変形部４５に対応する位置である。   As shown in FIG. 3, three cover-side deformation portions 55 are provided on the side surface portions 32, 33, and 34, respectively. The cover-side deformed portion 55 is a circularly deformed portion that is recessed when viewed from the outside and protrudes inward, and has substantially the same shape as the body-side deformed portion 45 of the body member 12. Further, the position of the cover side deformable portion 55 is a position corresponding to the main body side deformable portion 45 of the main body member 12.

上記したように、カバー部材１３は本体部材１２の外側をほぼ密着した状態で覆うことができるが、具体的には、カバー部材１３の開口３７から内部空間３６に向かって、本体部材１２を進入させ、本体部材１２の天面部２５側をカバー部材１３により覆うことにより行われる。   As described above, the cover member 13 can cover the outer side of the main body member 12 in a close contact state. Specifically, the main body member 12 enters from the opening 37 of the cover member 13 toward the internal space 36. The top surface 25 side of the main body member 12 is covered with the cover member 13.

そして、カバー部材１３が本体部材１２を覆って、カバー部材１３と本体部材１２とが重ね合わされると、図１、図２、図５、図９に示されるような状態となって、カバー部材１３によって本体部材１２の天面部２５の開口部２５ａを覆って閉鎖状態とすることができる。この状態では、本体部材１２の内部空間２６は、天面側はカバー部材１３の天面部３５によって、また、側面側は本体部材１２の側面部２１、２２、２３、２４によって覆われており、底面側は開口２７によって開口状である。
また、シールドケース１０では、カバー部材１３の内側の大きさと、本体部材１２の外形の大きさとがほぼ同じであり、本体部材１２とカバー部材１３とのガタがほとんどない状態である。 Then, when the cover member 13 covers the main body member 12 and the cover member 13 and the main body member 12 are overlapped, the state shown in FIGS. 1, 2, 5, and 9 is obtained. 13, the opening 25a of the top surface 25 of the main body member 12 can be covered and closed. In this state, the internal space 26 of the main body member 12 is covered on the top surface side by the top surface portion 35 of the cover member 13 and on the side surface side by the side surface portions 21, 22, 23, and 24 of the main body member 12, The bottom side is open by an opening 27.
In the shield case 10, the inner size of the cover member 13 and the outer shape of the main body member 12 are substantially the same, and there is almost no backlash between the main body member 12 and the cover member 13.

この状態では、カバー部材１３の軸部３０が、本体部材１２の軸保持部材２８，２９と側面部２１との間に保持され、本体部材１２の軸保持部材２８、２９の端部２８ｃ、２９ｃ付近が、貫通孔３８、３９に入っている。そして、図５に図示されるように、軸部３０は、軸保持部材２８，２９や貫通孔３８、３９の付近で、軸保持部材２８，２９及び側面部２１によって囲まれた状態となっており、軸部３０を保持した状態で回転させることができる。
また、この状態を言い換えると、本体部材１２の軸保持部材２８，２９とカバー部材１３の軸部３０によって、本体部材１２とカバー部材１３とが回転可能に連結している状態である。 In this state, the shaft portion 30 of the cover member 13 is held between the shaft holding members 28 and 29 of the main body member 12 and the side surface portion 21, and ends 28 c and 29 c of the shaft holding members 28 and 29 of the main body member 12. The vicinity is in the through holes 38 and 39. As shown in FIG. 5, the shaft portion 30 is surrounded by the shaft holding members 28 and 29 and the side surface portion 21 in the vicinity of the shaft holding members 28 and 29 and the through holes 38 and 39. And can be rotated while the shaft portion 30 is held.
In other words, the main body member 12 and the cover member 13 are rotatably connected by the shaft holding members 28 and 29 of the main body member 12 and the shaft portion 30 of the cover member 13.

さらに、図９に示されるように、カバー部材１３の側面部３２、３３、３４に設けられているカバー側変形部５５の内側が、本体部材１２の側面部２２、２３、２４に設けられている本体側変形部４５の外側に入り込む状態となる。   Further, as shown in FIG. 9, the inside of the cover side deformable portion 55 provided on the side surface portions 32, 33, 34 of the cover member 13 is provided on the side surface portions 22, 23, 24 of the main body member 12. The main body side deformable portion 45 enters the outside.

カバー部材１３を本体部材１２に取り付けて覆う際の、軸部３０が軸保持部材２８、２９に進入するときの動きや、カバー側変形部５５と本体側変形部４５とが係合するときの動きは以下の通りである。   When the cover member 13 is attached to and covered with the main body member 12, the movement when the shaft portion 30 enters the shaft holding members 28 and 29, and when the cover side deformation portion 55 and the main body side deformation portion 45 are engaged. The movement is as follows.

軸保持部材２８、２９にカバー部材１３の軸部３０が入る際には、図６に示されるように、軸保持部材２８、２９が外側に向かって弾性変形して行われる。なお、このとき、端部２８ｃ、２９ｃが外側に向かって傾斜しているので、スムーズにカバー部材１３を進入させることができる。
そして、一旦、軸部３０が進入して軸保持部材２８、２９によって保持されると、軸保持部材２８、２９が元に戻って軸部の脱出を阻止し、通常の操作では抜けることはない。 When the shaft portion 30 of the cover member 13 enters the shaft holding members 28 and 29, the shaft holding members 28 and 29 are elastically deformed outward as shown in FIG. At this time, since the end portions 28c and 29c are inclined outward, the cover member 13 can be smoothly entered.
Once the shaft portion 30 enters and is held by the shaft holding members 28 and 29, the shaft holding members 28 and 29 return to the original state to prevent the shaft portion from escaping and do not come out in a normal operation. .

カバー部材１３のカバー側変形部５５の内側が本体部材１２の本体側変形部４５に入って係合する際にも、本体部材１２の側面部２２、２３、２４やカバー部材１３の側面部３２、３３、３４などが弾性変形して行われる。   Even when the inside of the cover side deformable portion 55 of the cover member 13 enters and engages with the main body side deformable portion 45 of the main body member 12, the side surface portions 22, 23, 24 of the main body member 12 and the side surface portion 32 of the cover member 13. , 33, 34, etc. are elastically deformed.

また、カバー部材１３が本体部材１２を覆った状態から軸部３０を軸として回転させて、開くことが可能である。すなわち、軸部３０は側面部２１の下端に設けられており、軸部３０を軸として回転させた場合には、軸保持部材２８、２９の端部２８ｃ、２９ｃが軸部３０の上側に配置された貫通孔３８、３９に進入することになる。   Further, the cover member 13 can be opened by rotating the shaft portion 30 as an axis from the state where the body member 12 is covered. That is, the shaft portion 30 is provided at the lower end of the side surface portion 21, and when the shaft portion 30 is rotated about the shaft, the end portions 28 c and 29 c of the shaft holding members 28 and 29 are arranged above the shaft portion 30. The penetrating through holes 38 and 39 are entered.

そして、カバー部材１３を回転させて開くと、図７、図８に示されるような状態となる。また、シールドケース１０はカバー部材１３が開いた状態から、軸部３０を軸として回転させて閉じることもできる。カバー部材１３を回転させて開閉する場合にも、上記と同様にカバー側変形部５５の内側が本体部材１２の本体側変形部４５に入り込んで係合し、また、係合を解くことができる。   When the cover member 13 is rotated and opened, the state shown in FIGS. 7 and 8 is obtained. In addition, the shield case 10 can be closed from the state in which the cover member 13 is opened by rotating the shaft portion 30 as an axis. Even when the cover member 13 is rotated to open and close, the inside of the cover side deformable portion 55 enters and engages with the main body side deformable portion 45 of the main body member 12 as described above, and can be disengaged. .

このように、シールドケース１０では、カバー部材１３を回転させて開閉が可能であるので、カバー部材１３を閉じる際に本体部材１２に対する位置決め作業が不要となり作業を行いやすい。   As described above, in the shield case 10, the cover member 13 can be rotated to open and close, so that when the cover member 13 is closed, the positioning work with respect to the main body member 12 is not necessary, and the work is easy to perform.

上記の、軸部３０の進入、カバー側変形部５５と本体側変形部４５との係合・解除は、軸保持部材２８、２９や側面部３１、３２、３３、３４などに力が加わることにより、これら部材が弾性変形して行われる。   The approach of the shaft portion 30 and the engagement / release of the cover-side deformable portion 55 and the main body-side deformable portion 45 apply a force to the shaft holding members 28, 29 and the side surface portions 31, 32, 33, 34, etc. Thus, these members are elastically deformed.

また、シールドケース１０では、カバー部材１３を本体部材１２に取り付けて覆った状態では、本体部材１２とカバー部材１３とのガタがほとんどないので、本体部材１２にカバー部材１３を取り付けて覆った状態でカバー部材１３を移動させて本体部材１２の位置決めすることができる。
特に、本実施形態のシールドケース１０では、本体部材１２の側面部２１、２３の外側と、カバー部材１３の側面部３１、３３の内側との間にできるガタを小さくすることが可能である。これは、本体側変形部４５やカバー側変形部５５が側面部２３、側面部３３側にしか設けられていないので、ガタを小さくしても開閉が可能となるからである。 Further, in the shield case 10, there is almost no backlash between the main body member 12 and the cover member 13 in a state where the cover member 13 is attached to the main body member 12, so that the cover member 13 is attached to and covered with the main body member 12. Thus, the cover member 13 can be moved to position the main body member 12.
In particular, in the shield case 10 of the present embodiment, it is possible to reduce the backlash generated between the outside of the side surfaces 21 and 23 of the main body member 12 and the inside of the side surfaces 31 and 33 of the cover member 13. This is because the main body side deformable portion 45 and the cover side deformable portion 55 are provided only on the side surface portion 23 and the side surface portion 33 side, so that it can be opened and closed even if the backlash is reduced.

さらに、カバー部材１３を本体部材１２に取り付けて覆った状態では、軸部３０等のよって保持が確実であるので、カバー部材１３を本体部材１２に取り付けた状態で梱包などが可能となり、別々で梱包するよりもコンパクトとなる。   Further, in the state where the cover member 13 is attached to the main body member 12 and covered, the shaft portion 30 and the like are surely held, so that the cover member 13 can be packaged with the cover member 13 attached to the main body member 12 and separately. It becomes more compact than packing.

シールドケース１０の本体部材１２とカバー部材１３は、上記したように、金属板を折り曲げ加工して製造される。具体的には、本体部材１２は、金属板を図４（ｂ）に示されるような形状に切断し、折部２８ａ、２９ａ、４１、４２、４３、４４で折り曲げ、軸保持部材２８、２９と本体側変形部４５の変形加工を行う。そして、加工後は、折部２８ａ、２９ａ、４１、４２、４３、４４や軸保持部材２８、２９及び本体側変形部４５以外の部分は平面状となっている。   As described above, the main body member 12 and the cover member 13 of the shield case 10 are manufactured by bending a metal plate. Specifically, the main body member 12 cuts a metal plate into a shape as shown in FIG. 4B, and bends it at the folding portions 28a, 29a, 41, 42, 43, 44, and the shaft holding members 28, 29. The main body side deformation portion 45 is deformed. After processing, the portions other than the folding portions 28a, 29a, 41, 42, 43, 44, the shaft holding members 28, 29, and the main body side deforming portion 45 are flat.

カバー部材１３は、金属板を図４（ａ）に示されるような形状に切断し、折部５１、５２、５３、５４、５６で折り曲げ、カバー側変形部５５の変形加工を行う。そして、加工後は、折部５１、５２、５３、５４、５６及びカバー側変形部５５以外の部分は平面状となっている。   The cover member 13 cuts the metal plate into a shape as shown in FIG. 4A and bends the folded portions 51, 52, 53, 54, and 56 to perform deformation processing of the cover side deformable portion 55. And after processing, parts other than folding part 51,52,53,54,56 and the cover side deformation | transformation part 55 are planar.

本体部材１２の金属板の形状は、長方形の枠状の天面部２５の外側の４辺にそれぞれ折部４１、４２、４３、４４を介して側面部２１、２２、２３、２４が配置されており、さらに、側面部２１には折部２８ａ、２９ａを介して軸保持部材２８、２９が設けられている。軸保持部材２８、２９の付け根の折部２８ａ、２９ａの両側には、切り欠き６０が設けられ、折部２８ａ、２９ａで折り曲げを容易にして、折り曲げた状態で底面側に突出することを防止する。
天面部２５の内側に長方形の開口部２５ａがある。 The shape of the metal plate of the main body member 12 is such that the side surface portions 21, 22, 23, 24 are arranged on the four sides outside the rectangular frame-shaped top surface portion 25 via the folding portions 41, 42, 43, 44, respectively. Further, shaft holding members 28 and 29 are provided on the side surface portion 21 via folding portions 28a and 29a. Notches 60 are provided on both sides of the folds 28a and 29a at the bases of the shaft holding members 28 and 29 so that the folds 28a and 29a can be easily folded and prevented from protruding to the bottom side in the folded state. To do.
There is a rectangular opening 25 a inside the top surface portion 25.

カバー部材１３の金属板の形状は、長方形の天面部２５の外側の４辺にそれぞれ折部５１、５２、５３、５４を介して側面部３１、３２、３３、３４が配置されている。さらに、側面部３１には貫通孔３８、３９と折部５６が設けられている。   As for the shape of the metal plate of the cover member 13, the side surface portions 31, 32, 33, and 34 are arranged on the four outer sides of the rectangular top surface portion 25 via the folding portions 51, 52, 53, and 54, respectively. Further, the side surface portion 31 is provided with through holes 38 and 39 and a folding portion 56.

本体部材１２の折り曲げの方向や角度は、折部４１、４２、４３、４４を同じ方向にほぼ直角に曲げ、折部２８ａ、２９ａを逆にほぼ１８０°折り曲げる。そして、底面側に開口２７が形成される。
カバー部材１３の折り曲げの方向や角度は、折部５１、５２、５３、５４を同じ方向にほぼ直角に曲げ、折部５６を逆にほぼ１８０°折り曲げる。そして、底面側に開口３７が形成される。 The folding direction and angle of the main body member 12 are such that the folding portions 41, 42, 43, and 44 are bent at substantially right angles in the same direction, and the folding portions 28a and 29a are bent at approximately 180 °. An opening 27 is formed on the bottom side.
As for the direction and angle of bending of the cover member 13, the folding parts 51, 52, 53, 54 are bent almost at right angles to the same direction, and the folding part 56 is bent almost 180 °. An opening 37 is formed on the bottom side.

これらの切断や折り曲げは、プレス機などを用いて行うことができる。
また、本体部材１２やカバー部材１３の切断や折り曲げなどの加工の順は特に限定されるものではない。また、切断、折り曲げ、変形などの複数の加工を同時にして一つの工程で行ってもよい。 These cutting and bending can be performed using a press machine or the like.
The order of processing such as cutting and bending of the main body member 12 and the cover member 13 is not particularly limited. Moreover, you may perform several processes, such as a cutting | disconnection, bending, and a deformation | transformation, simultaneously in one process.

そして、製造された本体部材１２やカバー部材１３を嵌め合わせて、カバー部材１３を本体部材１２に取り付けて、図１に示すような状態にしてシールドケース１０が完成する。
この状態では、本体部材１２の内部空間２６は、カバー部材１３の天面部３５と、本体部材１２の側面部２１、２２、２３、２４によって覆われており、底面側は開口２７によって開放されている。 Then, the manufactured main body member 12 and the cover member 13 are fitted together, the cover member 13 is attached to the main body member 12, and the shield case 10 is completed in the state shown in FIG.
In this state, the internal space 26 of the main body member 12 is covered by the top surface portion 35 of the cover member 13 and the side surface portions 21, 22, 23, and 24 of the main body member 12, and the bottom surface side is opened by the opening 27. Yes.

なお、シールドケース１０の大きさや形状は、高周波回路８１の大きさに応じて選定される。したがって、天面側から見た外形が長方形状以外の形状でもよい。また、本実施形態では、開口部２５ａに図１０に示されるような吸着部１０６が設けられていないので、カバー部材１３の天面部３５の内側まで高周波回路８１を配置することができ、シールドケース１０の全体の厚みを小さくすることができる。言い換えると、本体部材１２の開口部２５ａの厚みの部分によってできる空間まで高周波回路８１の配置が可能である。   The size and shape of the shield case 10 are selected according to the size of the high frequency circuit 81. Therefore, the outer shape seen from the top surface side may be a shape other than the rectangular shape. Further, in the present embodiment, since the suction portion 106 as shown in FIG. 10 is not provided in the opening 25a, the high frequency circuit 81 can be disposed up to the inside of the top surface portion 35 of the cover member 13, and the shield case The total thickness of 10 can be reduced. In other words, the high frequency circuit 81 can be arranged up to a space formed by the thickness of the opening 25a of the main body member 12.

次に、シールドケース１０を基板８０に取り付ける。シールドケース１０の位置は、高周波回路８１がシールドケース１０によって覆われるような位置である。
このときの位置決めは、本体部材１２やカバー部材１３を取り付けて覆った状態で、カバー部材１３を移動させることによって行われる。そして、本体部材１２にカバー部材１３を取り付けて覆った状態でのガタが少ないために、カバー部材１３の移動による本体部材１２の位置決めが精度よくできる。
具体的には、カバー部材１３の天面部３５を用いて、図示しない吸引装置によってシールドケース１０を移動させるものであり、図１０に示されるようなシールドケース１００ののように、本実施形態の本体部材１２の天面側には吸着部１０６を設ける必要がない。 Next, the shield case 10 is attached to the substrate 80. The position of the shield case 10 is such a position that the high-frequency circuit 81 is covered by the shield case 10.
The positioning at this time is performed by moving the cover member 13 with the main body member 12 and the cover member 13 attached and covered. And since there is little backlash in the state which attached and covered the cover member 13 to the main body member 12, the positioning of the main body member 12 by the movement of the cover member 13 can be performed accurately.
Specifically, the shield case 10 is moved by a suction device (not shown) using the top surface portion 35 of the cover member 13, and like the shield case 100 as shown in FIG. It is not necessary to provide the suction portion 106 on the top surface side of the main body member 12.

そして、開口２７側を基板８０側として所定の位置に移動させ、本体部材１２と基板８０とをはんだ付けによって表面実装を行う。このとき、開口２７を形成する縁は所定の平面を形成しているので、開口２７と基板８０と密着させやすいので作業が行いやすく、また、シールド効果が高い。   Then, the opening 27 side is moved to a predetermined position with the substrate 80 side, and the body member 12 and the substrate 80 are surface-mounted by soldering. At this time, since the edge forming the opening 27 forms a predetermined plane, the opening 27 and the substrate 80 are easily brought into close contact with each other, so that the operation is easy and the shielding effect is high.

はんだ付けの方法は、基板８０のシールドケース１０が配置される位置にはんだペーストを塗布してシールドケース１０を配置し、高温の熱風炉に通してはんだを溶かして行われる。なお、はんだ付けの方法は他の方法であってもよい。   The soldering method is performed by applying the solder paste to the position where the shield case 10 of the substrate 80 is disposed, placing the shield case 10, and passing the solder case through a high-temperature hot air oven. The soldering method may be other methods.

はんだ付けが終わると、基板８０と本体部材１２とが完全に固定される。上記したように、カバー部材１３を上向きに引き離して取り外したり、或いは、軸部３０を軸として回転させることにより、本体部材１２の開口部２５ａが開放して、内部の高周波回路８１の点検、確認をすることができる。   When the soldering is finished, the substrate 80 and the main body member 12 are completely fixed. As described above, the cover member 13 is pulled upward and removed, or the shaft member 30 is rotated around the shaft 30 to open the opening 25a of the main body member 12, and the internal high-frequency circuit 81 is inspected and confirmed. Can do.

このカバー部材１３による開放操作は、軸部３０の設けられた側面部３１とは反対側の側面部３３側を引き上げて行われる。
特に、本実施形態のシールドケース１０では、軸部３０を保持したままカバー部材１３を回転させることにより本体部材１２の開口部２５ａの開放が行われるので、カバー部材１３を引き離して取り外して再び取り付ける場合に行われる嵌め合わせ作業が無く、開閉作業を行いやすい。 The opening operation by the cover member 13 is performed by pulling up the side surface portion 33 side opposite to the side surface portion 31 on which the shaft portion 30 is provided.
In particular, in the shield case 10 of the present embodiment, the opening 25a of the main body member 12 is opened by rotating the cover member 13 while holding the shaft portion 30, so that the cover member 13 is pulled apart and removed and reattached. There is no fitting work performed in some cases, and it is easy to perform opening and closing work.

また、軸部３０は幅方向の全域に設けられているので、強度が高く、カバー部材１３の開閉作業を繰り返して行っても破損しにくい。   Further, since the shaft portion 30 is provided in the entire region in the width direction, the strength is high, and the shaft portion 30 is not easily damaged even when the cover member 13 is repeatedly opened and closed.

上記の実施形態のシールドケース１０の本体部材１２及びカバー部材１３は、放熱の用の孔が設けられていなかったが、必要に応じて外部とつながる放熱用の孔を設けることができる。ただし、かかる孔の大きさや形状は、電磁波のシールドを行うために必要な範囲とすることが必要である。   The main body member 12 and the cover member 13 of the shield case 10 of the above embodiment are not provided with holes for heat dissipation, but can be provided with holes for heat dissipation connected to the outside as necessary. However, the size and shape of the hole needs to be in a range necessary for shielding electromagnetic waves.

本体部材１２は、天面側に開口部２５ａを設け、天面側に折部４１、４２、４３、４４が設けて折り曲げたものであったが、天面側及び底面側が開口を有していればよい。そしてこの開口は、金属板によってあらかじめ開口を設けたものでも良く、組立によって開口としたものでも良い。
例えば、本体部材１２を上記実施例とは逆向きに配置して、底面側に開口部２５ａを設け、底面側を折り曲げて天面側を開口状としてもよい。 The main body member 12 was formed by providing an opening 25a on the top surface side and bending portions 41, 42, 43, and 44 on the top surface side, but the top surface side and the bottom surface side have openings. Just do it. The opening may be provided in advance with a metal plate, or may be opened by assembling.
For example, the main body member 12 may be disposed in the opposite direction to the above embodiment, the opening 25a may be provided on the bottom surface side, the bottom surface side may be bent, and the top surface side may be opened.

側面部２２、２３、２４には本体側変形部４５が、側面部３２、３３、３４にはカバー側変形部５５が設けられているが、この形状は上記した実施形態以外の形状であってもよい。また、本体部材１２とカバー部材１３とを密着させて取り付けて覆った状態を維持できれば、本体側変形部４５及びカバー側変形部５５を設けなくてもよい。   The side surface portions 22, 23, and 24 are provided with main body side deformation portions 45, and the side surface portions 32, 33, and 34 are provided with cover side deformation portions 55, but this shape is a shape other than the embodiment described above. Also good. Further, the main body side deformable portion 45 and the cover side deformable portion 55 may not be provided as long as the main body member 12 and the cover member 13 can be kept in close contact with each other.

上記した実施形態では、一旦、軸部３０が進入して軸保持部材２８，２９によって保持されると、軸保持部材２８，２９が元に戻って軸部の脱出を阻止し、通常の操作では抜けないものであったが、カバー部材１３が本体部材１２に取り付けて覆った状態から、カバー部材１３を天面側に移動させて取り外すことができるようにしてもよい。
この場合には、軸部３０は軸保持部材２８，２９から離脱して、軸保持部材２８，２９による軸部３０の保持を解除し、カバー側変形部５５と本体側変形部４５とがはずれて、係合を解くことができるようにする。 In the above-described embodiment, once the shaft portion 30 enters and is held by the shaft holding members 28 and 29, the shaft holding members 28 and 29 return to the original state to prevent the shaft portion from escaping. The cover member 13 may be removed by moving the cover member 13 to the top surface side from the state where the cover member 13 is attached to and covered with the main body member 12.
In this case, the shaft portion 30 is detached from the shaft holding members 28 and 29 to release the holding of the shaft portion 30 by the shaft holding members 28 and 29, and the cover side deformation portion 55 and the main body side deformation portion 45 are disconnected. So that the engagement can be released.
