ところで、モールドケースの樹脂部分をネジの頭部とインサートナットとで挟持して固定する場合には、長期間の荷重により変形（クリープ）が生じ、樹脂部分がつぶれてネジ弛みが生ずるおそれがある。   By the way, when the resin part of the mold case is clamped and fixed between the screw head and the insert nut, deformation (creep) may occur due to a long-term load, and the resin part may be crushed and screw loosening may occur. .

本発明の課題は、このような樹脂製の部品をネジ等で固定してもクリープが生じず、ネジ弛みを防ぐことができる部品の固定構造及び電子機器を提供することである。   It is an object of the present invention to provide a component fixing structure and an electronic device that do not cause creep even when such a resin component is fixed with a screw or the like and can prevent screw loosening.

以上の課題を解決するため、請求項１に記載の発明は、第１の樹脂ケースと、第２の樹脂ケースと、ネジとからなる部品の固定構造であって、前記第１の樹脂ケースは、この樹脂ケースと一体成形され、端面がこの樹脂ケースの表面に露出した金属製のインサートナットを備え、前記第２の樹脂ケースは、この樹脂ケースの背面にインサート成形された金属プレートを備え、前記金属プレートは、取付孔を有し、前記第２の樹脂ケースは、前記取付孔と対向する位置に前記取付孔の内径よりも大きい内径の貫通孔を有し、前記ネジは、前記取付孔の内径より大きく前記貫通孔の内径より小さい外径の頭部と雄ネジ部を備え、前記ネジの雄ネジ部が前記第２の樹脂ケースの正面から前記取付孔と前記貫通孔に挿通されて前記第１の樹脂ケースのインサートナットの雌ネジ部に螺合されて前記第１の樹脂ケースと前記第２の樹脂ケースを接合することを特徴とする。 In order to solve the above-described problems, the invention described in claim 1 is a component fixing structure including a first resin case, a second resin case, and a screw, and the first resin case includes: The resin case is integrally formed with an end nut exposed on the surface of the resin case, and the second resin case includes a metal plate insert-molded on the back of the resin case . The metal plate has a mounting hole, the second resin case has a through-hole having an inner diameter larger than the inner diameter of the mounting hole at a position facing the mounting hole, and the screw has the mounting hole. And a male screw portion having an outer diameter larger than the inner diameter of the through hole and smaller than the inner diameter of the through hole, and the male screw portion of the screw is inserted into the mounting hole and the through hole from the front of the second resin case. Of the first resin case Screwed into the female screw portion of Nsatonatto characterized by bonding the second resin case and the first resin case.

請求項２に記載の発明は、電子機器であって、請求項１に記載の部品の固定構造を有することを特徴とする。 According to a second aspect of the invention, an electronic device, characterized by having a fixed structure component according to claim 1.

以下、本発明の第１の実施の形態として、携帯電話機について詳細に説明する。図１は本実施の形態に係る携帯電話機１の一部を分解した分解斜視図である。この携帯電話機１は２軸ヒンジを有する折り畳み式である。携帯電話機１は、操作部筐体２と、表示部筐体４と、操作部筐体２と表示部筐体４との端部を接続する支持筐体３と、等から概略構成されている。   Hereinafter, a mobile phone will be described in detail as a first embodiment of the present invention. FIG. 1 is an exploded perspective view in which a part of the mobile phone 1 according to the present embodiment is disassembled. The mobile phone 1 is a foldable type having a biaxial hinge. The mobile phone 1 is schematically configured from an operation unit housing 2, a display unit housing 4, a support housing 3 that connects ends of the operation unit housing 2 and the display unit housing 4, and the like. .

支持筐体３は、操作部筐体２の一端と左右２箇所で接続され、操作部筐体２に対して回転可能に設けられている。このため、表示部筐体４及び支持筐体３を操作部筐体２に対して重ね合わせることができ、携帯電話機１を折り畳み可能としている。   The support housing 3 is connected to one end of the operation unit housing 2 at two positions on the left and right sides, and is provided to be rotatable with respect to the operation unit housing 2. For this reason, the display unit case 4 and the support case 3 can be overlapped with the operation unit case 2, and the mobile phone 1 can be folded.

また、支持筐体３の左右方向の中央部には、支持筐体３と表示部筐体４と接続するヒンジ３２が設けられている。ヒンジ３２は、表示部筐体４と、支持筐体３とを回転可能とするとともに、表示部筐体４と、支持筐体３が１８０度回転した位置において面一となるような状態で安定するように保持する。   In addition, a hinge 32 that connects the support housing 3 and the display housing 4 is provided at the center in the left-right direction of the support housing 3. The hinge 32 enables the display unit housing 4 and the support housing 3 to rotate, and is stable in a state where the display unit housing 4 and the support housing 3 are flush with each other at a position rotated 180 degrees. Hold on.

図１では、表示部筐体４が分解されている。表示部筐体４は、ヒンジ３２が固定される背面ケース４０と、背面ケース４０に固定される前面ケース５０と、前面ケース５０を背面ケース４０に固定するネジ６０と、等を備える。なお、前面ケース５０は枠状の樹脂ケース５３の背面側にプレート５２が一体となるように設けられ、図示しない表示装置が収納される収納凹部５１が形成されている。プレート５２は図２に示すように、ネジ６０が挿入される取付孔５４の位置まで延在し、樹脂ケース５３に設けられた孔５５から露出されている。
背面ケース４０には表示装置と操作部筐体２内の電子回路とを接続する図示しないＦＰＣ等が収納される。 In FIG. 1, the display unit housing 4 is disassembled. The display unit housing 4 includes a rear case 40 to which the hinge 32 is fixed, a front case 50 fixed to the rear case 40, a screw 60 that fixes the front case 50 to the rear case 40, and the like. The front case 50 is provided on the back side of the frame-shaped resin case 53 so that the plate 52 is integrated, and a storage recess 51 for storing a display device (not shown) is formed. As shown in FIG. 2, the plate 52 extends to the position of the mounting hole 54 into which the screw 60 is inserted, and is exposed from a hole 55 provided in the resin case 53.
The rear case 40 accommodates an FPC (not shown) that connects the display device and the electronic circuit in the operation unit housing 2.

図２は図１のII−II矢視断面図である。前面ケース５０は、樹脂ケース５３と内部の金属製のプレート５２とが一体となるようにインサート成形してなるモールドケースである。プレート５２は前面ケース５０の強度を保つとともに、電磁的なシールド、さらに電気的なグラウンドとしても機能する。樹脂ケース５３は外部からの衝撃を吸収する役割を果たす。   2 is a cross-sectional view taken along the line II-II in FIG. The front case 50 is a mold case formed by insert molding so that the resin case 53 and the internal metal plate 52 are integrated. The plate 52 maintains the strength of the front case 50 and also functions as an electromagnetic shield and further as an electrical ground. The resin case 53 serves to absorb external impacts.

図１、図２に示すように、プレート５２には、ネジ６０が挿通される取付孔５４が設けられている。樹脂ケース５３には、取付孔５４よりも内径が大きく、取付孔５４の周囲においてプレート５２を露出させる孔５５が設けられている。   As shown in FIGS. 1 and 2, the plate 52 is provided with a mounting hole 54 through which the screw 60 is inserted. The resin case 53 is provided with a hole 55 having an inner diameter larger than that of the mounting hole 54 and exposing the plate 52 around the mounting hole 54.

図３はネジ６０による前面ケース５０と背面ケース４０との接合部の断面図である。図３に示すように、背面ケース４０は、樹脂ケース４３の内部にインサートナット４２が一体となるように設けられている。   FIG. 3 is a cross-sectional view of a joint portion between the front case 50 and the rear case 40 by the screw 60. As shown in FIG. 3, the back case 40 is provided in the resin case 43 so that the insert nut 42 is integrated.

前面ケース５０と背面ケース４０とをネジ６０により接合するには、ネジ６０のネジ部６１を取付孔５４に挿通し、インサートナット４２に螺合させる。このとき、図３に示すように、ネジ６０の頭部６２とインサートナット４２との間にプレート５２が挟持される。プレート５２は金属製であるため、ネジ６０の頭部６２とインサートナット４２とで長期間挟持されても、クリープが生じない。このため、ネジ弛みを防ぐことができる。   In order to join the front case 50 and the rear case 40 with the screw 60, the screw portion 61 of the screw 60 is inserted into the mounting hole 54 and screwed into the insert nut 42. At this time, as shown in FIG. 3, the plate 52 is sandwiched between the head 62 of the screw 60 and the insert nut 42. Since the plate 52 is made of metal, creep does not occur even if it is sandwiched between the head portion 62 of the screw 60 and the insert nut 42 for a long period of time. For this reason, screw loosening can be prevented.

なお、本実施の形態においては、インサートナット４２にモールドケースを固定する場合について説明したが、例えば、図４に示すように、金属製のヒンジ３２に前面ケース５０を固定する場合に、ネジ６０の頭部６２とヒンジ３２との間でプレート５２を挟持させてもよい。また、ネジの代わりにリベットやＥ形止め輪を用いてもよい。   In the present embodiment, the case where the mold case is fixed to the insert nut 42 has been described. For example, when the front case 50 is fixed to the metal hinge 32 as shown in FIG. The plate 52 may be sandwiched between the head 62 and the hinge 32. A rivet or E-shaped retaining ring may be used instead of the screw.

また、上記実施形態においては、携帯電話機について説明したが、本発明はこれに限らず、カメラ、ＰＤＡ、ノートパソコン、ウェアラブルパソコン、電卓、電子辞書等の電子機器の筐体にも適用可能である。さらに、自動車等に用いられるパネルの固定にも応用することができる。この場合には、プッシュリベットにより固定する構造としてもよい。   In the above embodiment, a mobile phone has been described. However, the present invention is not limited to this, and the present invention is also applicable to a housing of an electronic device such as a camera, a PDA, a notebook computer, a wearable computer, a calculator, and an electronic dictionary. . Furthermore, it can be applied to fixing panels used in automobiles and the like. In this case, it is good also as a structure fixed with a push rivet.
