Abstract

A second measurement (H2) from a base end part of a guide part (42) to a leading end part thereof is larger than a first measurement (H1) between an O-ring (34) and a flange part (32). When passing a nut member (30) through a through hole (41), the guide part (42) hooks with a step part (35) of the flange part (32) before the O-ring (34) makes contact with the inner circumference face of the through hole (41), and initiates the guiding. Even when the O-ring (34) is disposed on the circumference face of the nut member (30), it is possible to insert the nut member (30) in an accurate site and state with respect to the through hole (41).

Description

電子機器Electronics

　本発明は、防水機能を有し、防水領域内部の電子部品と非防水領域の部品とを電気的に接続した電子機器に関するものである。 The present invention relates to an electronic device having a waterproof function and electrically connecting an electronic component inside the waterproof region and a component in the non-waterproof region.

　従来より、締結する際に回転を防止するナット部材が知られている（例えば、特許文献１参照）。
　特許文献１に記載のナット部材には、軸方向に突出する回転防止用の突起が設けられている。
　このようなナット部材を、防水領域内部の電子部品と非防水領域の部品との電気的接続に用いる場合、防水性を得るためにナット部材の側面にＯリングを設ける場合がある。 Conventionally, a nut member that prevents rotation when fastening is known (for example, see Patent Document 1).
The nut member described in Patent Document 1 is provided with a rotation-preventing protrusion that protrudes in the axial direction.
When such a nut member is used for electrical connection between an electronic component inside the waterproof region and a component in the non-waterproof region, an O-ring may be provided on the side surface of the nut member in order to obtain waterproofness.

　しかしながら、前述したように、ナット部材にＯリングを設けた場合、ナット部材が最終的な位置に収まる前に、Ｏリングが挿入孔の内周面に対して摺接を開始する場合がある。このため、Ｏリングが摺接抵抗となってナット部材を正規の位置に位置決めしにくいという問題があった。 However, as described above, when the O-ring is provided on the nut member, the O-ring may start sliding contact with the inner peripheral surface of the insertion hole before the nut member is in the final position. For this reason, there existed a problem that an O-ring became sliding contact resistance and it was difficult to position a nut member in a regular position.

　本発明は、従来の問題を解決するためになされたもので、ナット部材等の金属部材の外周面に防水のためのＯリングが設けられていても、金属部材を貫通孔に対して正規の位置、状態に挿入できる電子機器を提供することを目的とする。 The present invention has been made to solve the conventional problems. Even when an O-ring for waterproofing is provided on the outer peripheral surface of a metal member such as a nut member, the metal member is properly connected to the through-hole. An object is to provide an electronic device that can be inserted into a position and a state.

　本発明の電子機器は、防水領域と非防水領域との間に貫通孔を備えた携帯端末において、前記貫通孔に挿入され、前記防水領域内の部品と前記非防水領域内の部品とを電気的に接続する略円柱形状の金属部材と、前記金属部材の外周面に設けられ、前記貫通孔の内周面に接触するＯリングと、前記金属部材の前記防水領域側端部に設けられた鍔部と、前記金属部材の径方向に沿って前記鍔部に設けられた段差部と、前記貫通孔の開口縁部から前記防水領域に突設され、前記段差部を案内する案内部と、を備え、前記Ｏリングと前記鍔部との間の第１寸法よりも、前記案内部の基端部から先端部までの第２寸法が大きいものである。 The electronic device of the present invention is a portable terminal having a through hole between a waterproof region and a non-waterproof region, and is inserted into the through hole to electrically connect the component in the waterproof region and the component in the non-waterproof region. A substantially cylindrical metal member to be connected, an O-ring provided on the outer peripheral surface of the metal member and in contact with the inner peripheral surface of the through hole, and provided on the end of the waterproof region on the metal member A flange portion, a step portion provided in the flange portion along the radial direction of the metal member, a guide portion that protrudes from the opening edge portion of the through hole to the waterproof region and guides the step portion; The second dimension from the base end part to the tip end part of the guide part is larger than the first dimension between the O-ring and the flange part.

　また、本発明の電子機器は、前記鍔部の径方向に沿った対称位置に一対設けられた凹部を備えたものである。 Further, the electronic apparatus of the present invention includes a pair of concave portions provided at symmetrical positions along the radial direction of the collar portion.

　また、本発明の電子機器は、前記段差部が前記凹部と同形状であるものである。 Further, in the electronic device of the present invention, the step portion has the same shape as the concave portion.

　また、本発明の電子機器は、前記段差部における前記金属部材側の縁部に傾斜面が設けられたものである。 Moreover, the electronic device of the present invention is such that an inclined surface is provided at an edge of the step portion on the metal member side.

　さらに、本発明の電子機器は、前記金属部材の前記鍔部に接続された板金部材を有し、前記板金部材が、前記鍔部の前記一対の凹部に係合し、かつ、前記鍔部の天面の少なくとも一部を覆う被覆部と、前記被覆部に連結され、前記鍔部の側面の近傍において接地する接地部と、を備えるものである。 Furthermore, the electronic device of the present invention has a sheet metal member connected to the flange portion of the metal member, the sheet metal member engages with the pair of recesses of the flange portion, and the A covering portion that covers at least a part of the top surface, and a grounding portion that is connected to the covering portion and is grounded in the vicinity of the side surface of the flange portion.

　本発明は、ナット部材におけるＯリングと鍔部との間の第１寸法よりも、壁部における案内部の基端部から先端部までの第２寸法を大きくしたので、貫通孔にナット部材を挿入する際に、貫通孔の内周面にＯリングが接触するよりも先に案内部が段差部に係合する。このため、ナット部材の周面にＯリングが設けられていても、ナット部材を貫通孔に対して正規の位置、状態に挿入できるという効果を有する電子機器を提供できる。 In the present invention, since the second dimension from the base end part to the tip end part of the guide part in the wall part is larger than the first dimension between the O-ring and the flange part in the nut member, the nut member is provided in the through hole. When inserting, the guide part engages with the step part before the O-ring contacts the inner peripheral surface of the through hole. For this reason, even if an O-ring is provided on the peripheral surface of the nut member, it is possible to provide an electronic apparatus having an effect that the nut member can be inserted into a normal position and state with respect to the through hole.

The cover 22 is a rectangular plate-like member, and is attached to the upper end portion (the upper end portion in FIG. 1) of the vertical wall 24 of the case 21 in a state having water tightness.
Therefore, the internal space formed by the case 21 and the cover 22 is the waterproof region 11, and the outside of the housing 20 is the non-waterproof region 12.

　図１および図２に示すように、筐体２０の内部空間には回路基板２５が取り付けられる。回路基板２５には、回路基板２５の下面（図１中下面）から下方へ突出する板ばね状の接点部材２５１（図６参照）が設けられている。
　また、ケース２１のベースプレート２３の外面２３２には、携帯端末用のアンテナ部材２６が取り付けられる。アンテナ部材２６は、棒状のアンテナ本体２６１と、アンテナ本体２６１の基端部に設けられた板状の取付板２６２を有する。取付板２６２の中央には、ねじ孔２６３が設けられている。
　防水領域１１の回路基板２５と非防水領域１２のアンテナ部材２６とは、詳細を後述する金属部材であるナット部材３０を介して電気的に接続される。 As shown in FIGS. 1 and 2, a circuit board 25 is attached to the internal space of the housing 20. The circuit board 25 is provided with a leaf spring-shaped contact member 251 (see FIG. 6) that protrudes downward from the lower surface of the circuit board 25 (the lower surface in FIG. 1).
An antenna member 26 for a portable terminal is attached to the outer surface 232 of the base plate 23 of the case 21. The antenna member 26 includes a rod-shaped antenna main body 261 and a plate-shaped attachment plate 262 provided at the base end portion of the antenna main body 261. A screw hole 263 is provided in the center of the mounting plate 262.
The circuit board 25 in the waterproof region 11 and the antenna member 26 in the non-waterproof region 12 are electrically connected via a nut member 30 which is a metal member described in detail later.

　筐体２０の隅部であるケース２１のベースプレート２３の内面２３１隅部には、防水領域１１と非防水領域１２とを区画する壁部４０が設けられており、壁部４０およびベースプレート２３を貫通する貫通孔４１が設けられている。
　従って、貫通孔４１の周囲は全周に亘って壁部４０により囲まれており、貫通孔４１は、防水領域１１である筐体２０の内部空間と、非防水領域１２である筐体２０の外側とを連通する。 A wall 40 that partitions the waterproof region 11 and the non-waterproof region 12 is provided at the corner of the inner surface 231 of the base plate 23 of the case 21, which is a corner of the housing 20, and penetrates the wall 40 and the base plate 23. A through-hole 41 is provided.
Therefore, the perimeter of the through hole 41 is surrounded by the wall 40 over the entire circumference, and the through hole 41 is formed between the internal space of the housing 20 that is the waterproof region 11 and the housing 20 that is the non-waterproof region 12. Communicate with the outside.

　図３に示すように、貫通孔４１の開口縁部である壁部４０の上面４０１（図３において上面）には、貫通孔４１を挟んで対称位置に、防水領域１１側（ケース２１内面側）へ突出する一対の案内部としてのガイド柱４２，４２が設けられている。
　ガイド柱４２は、例えば矩形断面の柱状部材とすることができる。ここで、ガイド柱４２の基端部４２１から先端部４２２までの高さ（第２寸法）をＨ２とする。 As shown in FIG. 3, on the upper surface 401 (upper surface in FIG. 3) of the wall portion 40 that is the opening edge of the through hole 41, the waterproof region 11 side (the inner surface side of the case 21) is located symmetrically across the through hole 41. Guide pillars 42 and 42 are provided as a pair of guide portions projecting to).
The guide column 42 may be a columnar member having a rectangular cross section, for example. Here, the height (second dimension) from the base end portion 421 to the tip end portion 422 of the guide column 42 is set to H2.

　図３に示すように、ナット部材３０は、貫通孔４１に挿通可能な外形を有する略円柱形状の本体部３１と、本体部３１の上端に設けられて貫通孔４１の外径より大きな外径の鍔部３２とを有する。
　鍔部３２には、対称位置に一対の段差部３５，３５が設けられている。段差部３５は、外周縁から径方向内側に凹んで形成されており、壁部４０に設けられているガイド柱４２に嵌合することにより、回転防止して摺動可能となっている。段差部３５におけるナット部材３０側の縁部、すなわち、鍔部３２の下面３２１における段差部３５の基端部には、傾斜面３５１が設けられている（図４参照）。 As shown in FIG. 3, the nut member 30 has a substantially cylindrical main body 31 having an outer shape that can be inserted into the through hole 41, and an outer diameter that is provided at the upper end of the main body 31 and is larger than the outer diameter of the through hole 41. And the collar portion 32.
The flange portion 32 is provided with a pair of step portions 35 and 35 at symmetrical positions. The step portion 35 is formed to be recessed inward in the radial direction from the outer peripheral edge, and is fitted to a guide column 42 provided on the wall portion 40 so as to prevent rotation and slide. An inclined surface 351 is provided at an edge of the stepped portion 35 on the nut member 30 side, that is, a base end portion of the stepped portion 35 on the lower surface 321 of the flange portion 32 (see FIG. 4).

　また、鍔部３２の外周縁には、一対の段差部３５，３５の間に、一対の凹部３６，３６を設けるのが望ましい。この凹部３６は、ナット部材３０を取り付ける際に、ナット部材３０を挟持するピンセット等の工具の先端が嵌合可能な大きさおよび形状を有する。
　なお、凹部３６の大きさおよび形状を、段差部３５と同様に形成するのが望ましい。これにより、段差部３５と凹部３６とを区別する必要がなくなり、ナット部材３０の回転向きの自由度が増すので作業性が向上する。 In addition, it is desirable to provide a pair of recesses 36, 36 between the pair of stepped portions 35, 35 on the outer peripheral edge of the flange portion 32. The concave portion 36 has a size and a shape that allow the tip of a tool such as tweezers that sandwich the nut member 30 to be fitted when the nut member 30 is attached.
It is desirable that the size and shape of the recess 36 be formed in the same manner as the stepped portion 35. Thereby, it becomes unnecessary to distinguish the step part 35 and the recessed part 36, and since the freedom degree of the rotation direction of the nut member 30 increases, workability | operativity improves.

　図４に示すように、本体部３１には、全周に亘って例えば矩形断面の溝３３が形成されており、溝３３には、Ｏリング３４が取り付けられる。Ｏリング３４は、一部が本体部３１の外周面３１１から外側へ突出するように取り付けられており、溝３３内部に収容されるような弾性変形が可能となっている。 As shown in FIG. 4, a groove 33 having, for example, a rectangular cross section is formed in the main body 31 over the entire circumference, and an O-ring 34 is attached to the groove 33. The O-ring 34 is attached so that a part thereof protrudes outward from the outer peripheral surface 311 of the main body 31, and can be elastically deformed so as to be accommodated in the groove 33.

　ここで、Ｏリング３４の下端部と鍔部３２の下面３２１との間の寸法である第１寸法Ｈ１を、ガイド柱４２の基端部４２１から先端部４２２までの寸法である第２寸法Ｈ２よりも小さく設定する。
　また、本体部３１の底面３１２には、アンテナ部材２６取付用のねじ孔３７が設けられている。このねじ孔３７は、鍔部３２を貫通しない長さで設けられている。 Here, a first dimension H1 that is a dimension between the lower end portion of the O-ring 34 and the lower surface 321 of the flange portion 32 is a second dimension H2 that is a dimension from the proximal end portion 421 to the distal end portion 422 of the guide column 42. Set smaller than.
A screw hole 37 for attaching the antenna member 26 is provided on the bottom surface 312 of the main body 31. The screw hole 37 is provided with a length that does not penetrate the flange portion 32.

　次に、回路基板２５とアンテナ部材２６との接続作業について説明する。なお、回路基板２５は、予めベースプレート２３に取り付けられている。
　まず、図３に示すように、ナット部材３０を筐体２０の貫通孔４１に取り付ける。このとき、ピンセット等の工具の先端で鍔部３２の凹部３６を把持して、ナット部材３０の段差部３５が、貫通孔４１の外周に設けられているガイド柱４２に対応するように、回転方向の位置決めをする。
　なお、段差部３５と凹部３６とを同形状に形成しているので、ピンセット等で段差部３５を把持し、凹部３６をガイド柱４２に対応するように位置決めすることもできる。 Next, connection work between the circuit board 25 and the antenna member 26 will be described. The circuit board 25 is attached to the base plate 23 in advance.
First, as shown in FIG. 3, the nut member 30 is attached to the through hole 41 of the housing 20. At this time, the concave portion 36 of the flange portion 32 is gripped by the tip of a tool such as tweezers, and the stepped portion 35 of the nut member 30 is rotated so as to correspond to the guide column 42 provided on the outer periphery of the through hole 41. Position the direction.
Since the stepped portion 35 and the recessed portion 36 are formed in the same shape, the stepped portion 35 can be gripped by tweezers or the like, and the recessed portion 36 can be positioned so as to correspond to the guide column 42.

　そして、ナット部材３０の本体部３１を貫通孔４１に挿嵌すると、ガイド柱４２の先端部４２２がナット部材３０の段差部３５に嵌合する。このとき、ナット部材３０におけるＯリング３４と鍔部３２との間の第１寸法Ｈ１よりも、壁部４０におけるガイド柱４２の基端部４２１から先端部４２２までの第２寸法Ｈ２のほうが大きいので、まず、ガイド柱４２が段差部３５に係合して回転方向の案内を開始する（図５に示す状態）。
　その後、ナット部材３０をさらに貫通孔４１に押し込むと、Ｏリング３４が貫通孔４１の内周面４１１に接触する。このとき、Ｏリング３４は弾性力により貫通孔４１の内面に押し付けられるので、水密性を確保できる。 Then, when the main body portion 31 of the nut member 30 is inserted into the through hole 41, the tip end portion 422 of the guide column 42 is fitted into the stepped portion 35 of the nut member 30. At this time, the second dimension H2 from the base end part 421 to the tip end part 422 of the guide column 42 in the wall part 40 is larger than the first dimension H1 between the O-ring 34 and the flange part 32 in the nut member 30. Therefore, first, the guide column 42 is engaged with the step portion 35 to start the rotation direction guidance (state shown in FIG. 5).
Thereafter, when the nut member 30 is further pushed into the through hole 41, the O-ring 34 comes into contact with the inner peripheral surface 411 of the through hole 41. At this time, since the O-ring 34 is pressed against the inner surface of the through hole 41 by elastic force, water tightness can be ensured.

　そして、図６に示すように、ナット部材３０の鍔部３２の下面３２１が、壁部４０の上面４０１に当接するまで、ナット部材３０を押し込む。ナット部材３０は、Ｏリング３４の弾性力により，貫通孔４１の内面に固定される。これにより、ナット部材３０の底面３１２が、回路基板２５の接点部材２５１を弾性変形させて接触する。
　次いで、固定ビス２７をアンテナ部材２６の取付板２６２のねじ孔２６３に挿通し、さらに固定ビス２７をナット部材３０のねじ孔３７に締結して、アンテナ部材２６をナット部材３０に固定する。 Then, as shown in FIG. 6, the nut member 30 is pushed in until the lower surface 321 of the flange portion 32 of the nut member 30 contacts the upper surface 401 of the wall portion 40. The nut member 30 is fixed to the inner surface of the through hole 41 by the elastic force of the O-ring 34. As a result, the bottom surface 312 of the nut member 30 contacts the contact member 251 of the circuit board 25 by elastic deformation.
Next, the fixing screw 27 is inserted into the screw hole 263 of the mounting plate 262 of the antenna member 26, and the fixing screw 27 is fastened to the screw hole 37 of the nut member 30 to fix the antenna member 26 to the nut member 30.

　これにより、非防水領域１２のアンテナ部材２６と、防水領域１１の回路基板２５とが、電気的に接続される。
　このとき、ナット部材３０の底面３１２とアンテナ部材２６の取付板２６２との間に、わずかに隙間Ｇが設けられるようにするのが望ましい。
　これにより、固定ビス２７を締め付けた際に、取付板２６２がナット部材３０側に弾性変形するので、アンテナ部材２６を確実に取り付けることができる。また、取付板２６２の弾性力が、ナット部材３０を壁部４０の上面４０１に押し付ける方向に付勢するので、ナット部材３０が貫通孔４１から脱落するのを確実に防止できる。 As a result, the antenna member 26 in the non-waterproof area 12 and the circuit board 25 in the waterproof area 11 are electrically connected.
At this time, it is desirable that a slight gap G is provided between the bottom surface 312 of the nut member 30 and the mounting plate 262 of the antenna member 26.
Thus, when the fixing screw 27 is tightened, the mounting plate 262 is elastically deformed toward the nut member 30, so that the antenna member 26 can be securely attached. Further, since the elastic force of the mounting plate 262 biases the nut member 30 in the direction of pressing the nut member 30 against the upper surface 401 of the wall portion 40, the nut member 30 can be reliably prevented from falling out of the through hole 41.

　以上、説明した本発明に係る第１実施形態の電子機器１０によれば、防水領域１１と非防水領域１２とを区画する筐体２０の壁部４０に設けられた貫通孔４１にナット部材３０を挿嵌し、固定ビス２７によりアンテナ部材２６をナット部材３０の非防水領域１２側に取り付ける。防水領域１１の回路基板２５に設けられている接点部材２５１が、ナット部材３０の防水領域１１側端部に接触するので、アンテナ部材２６は固定ビス２７、ナット部材３０および接点部材２５１を介して回路基板２５に電気的に接続される。
　このとき、ナット部材３０が略円柱形状であるため、従来の多角柱形状のナット部材のように、貫通孔４１の内面に対して食い付き等が生じず、誤挿入の虞がない。 As described above, according to the electronic apparatus 10 according to the first embodiment of the present invention described above, the nut member 30 is inserted into the through hole 41 provided in the wall portion 40 of the housing 20 that partitions the waterproof region 11 and the non-waterproof region 12. And the antenna member 26 is attached to the non-waterproof region 12 side of the nut member 30 with a fixing screw 27. Since the contact member 251 provided on the circuit board 25 in the waterproof region 11 comes into contact with the end of the nut member 30 on the waterproof region 11 side, the antenna member 26 is connected via the fixing screw 27, the nut member 30 and the contact member 251. It is electrically connected to the circuit board 25.
At this time, since the nut member 30 has a substantially columnar shape, the inner surface of the through hole 41 does not bite or the like, unlike the conventional polygonal column-shaped nut member, and there is no risk of erroneous insertion.

　また、ナット部材３０の防水領域１１側端部には鍔部３２が設けられており、この鍔部３２には，ナット部材３０の径方向に沿って段差部３５が設けられている。さらに、ナット部材３０の外周面３１１には、壁部４０の貫通孔４１の内周面４１１に接触するＯリング３４が設けられている。
　一方、壁部４０には、段差部３５を案内するガイド柱４２が、貫通孔４１の開口縁部から防水領域１１に突設されている。 A flange 32 is provided at the end of the nut member 30 on the waterproof region 11 side, and a step 35 is provided in the flange 32 along the radial direction of the nut member 30. Further, an O-ring 34 that contacts the inner peripheral surface 411 of the through hole 41 of the wall portion 40 is provided on the outer peripheral surface 311 of the nut member 30.
On the other hand, a guide column 42 for guiding the stepped portion 35 is provided on the wall portion 40 so as to protrude from the opening edge portion of the through hole 41 to the waterproof region 11.

　そして、ナット部材３０におけるＯリング３４と鍔部３２との間の第１寸法Ｈ１よりも、壁部４０におけるガイド柱４２の基端部から先端部までの第２寸法Ｈ２のほうを大きく設定している。このため、貫通孔４１にナット部材３０を挿入する際に、貫通孔４１の内周面４１１にＯリング３４が接触するよりも先に、ガイド柱４２が段差部３５に係合して案内を開始することになる。
　これにより、従来のように、ナット部材３０の外周面３１１にＯリング３４が設けられていても、ナット部材３０を貫通孔４１に対して正規の位置、状態に挿入できる。 Then, the second dimension H2 from the proximal end portion to the distal end portion of the guide pillar 42 in the wall portion 40 is set larger than the first dimension H1 between the O-ring 34 and the flange portion 32 in the nut member 30. ing. For this reason, when the nut member 30 is inserted into the through hole 41, the guide column 42 engages with the step portion 35 and guides before the O ring 34 contacts the inner peripheral surface 411 of the through hole 41. Will start.
Thereby, even if the O-ring 34 is provided on the outer peripheral surface 311 of the nut member 30 as in the prior art, the nut member 30 can be inserted into the normal position and state with respect to the through hole 41.

　また、本発明の電子機器１０では、鍔部３２の径方向に沿った対称位置に設けられた凹部３６に、ピンセット等の工具の先端を嵌合して容易にナット部材３０を挟持でき、貫通孔４１に挿入および回転等して取り付けることができる。 Moreover, in the electronic device 10 of the present invention, the nut member 30 can be easily sandwiched by fitting the tip of a tool such as tweezers into the recess 36 provided at a symmetrical position along the radial direction of the flange 32. The hole 41 can be inserted and rotated.

　また、本発明の電子機器１０では、凹部３６をピンセット等の工具で挟持し、段差部３５に壁部４０のガイド柱４２を嵌合させてナット部材３０を貫通孔４１に取り付ける。この際に、ピンセット等がガイド柱４２に干渉しないので、容易にナット部材３０を取り付けることができる。
　また、段差部３５と凹部３６とが同形状であるので、ピンセット等で段差部３５を挟持し、凹部３６に壁部４０のガイド柱４２を嵌合させて案内することもできる。このため、ナット部材３０の回転位置にかかわらず，ナット部材３０を容易に貫通孔４１に取り付けることができる。 Further, in the electronic device 10 of the present invention, the recess 36 is sandwiched with a tool such as tweezers, the guide column 42 of the wall 40 is fitted to the step 35 and the nut member 30 is attached to the through hole 41. At this time, since the tweezers and the like do not interfere with the guide pillar 42, the nut member 30 can be easily attached.
Further, since the stepped portion 35 and the recessed portion 36 have the same shape, the stepped portion 35 can be sandwiched with tweezers or the like, and the guide pillar 42 of the wall portion 40 can be fitted into the recessed portion 36 and guided. For this reason, the nut member 30 can be easily attached to the through hole 41 regardless of the rotational position of the nut member 30.

　さらに、本発明の電子機器１０では、段差部３５におけるナット部材３０側の縁部に傾斜面３５１が設けられているので、貫通孔４１の形状に応じて筐体２０の壁部４０に係合しやすくなる。 Furthermore, in the electronic device 10 of the present invention, since the inclined surface 351 is provided at the edge of the step portion 35 on the nut member 30 side, the wall portion 40 of the housing 20 is engaged according to the shape of the through hole 41. It becomes easy to do.

（第２実施形態）
　次に、本発明に係る第２実施形態の電子機器について、図面を用いて説明する。
　なお、前述した第１実施形態に係る電子機器１０と共通する部位には同じ符号を付して、重複する説明を省略することとする。
　図７および図８に示すように、本発明に係る第２実施形態の電子機器１０Ｂでは、ナット部材３０の鍔部３２に、板金部材５０が取り付けられて接続される。 (Second Embodiment)
Next, an electronic apparatus according to a second embodiment of the invention will be described with reference to the drawings.
In addition, the same code | symbol is attached | subjected to the site | part which is common in the electronic device 10 which concerns on 1st Embodiment mentioned above, and the overlapping description is abbreviate | omitted.
As shown in FIGS. 7 and 8, in the electronic device 10 </ b> B according to the second embodiment of the present invention, a sheet metal member 50 is attached to and connected to the flange portion 32 of the nut member 30.

　図９にも示すように、板金部材５０は、アンテナ部材２６を固定するとともに電気的に接続される金属部材であるナット部材３０と、回路基板２５とを電気的に接続するとともに、回路基板２５等を接地するための部材である。
　図１０（Ａ）に示すように、板金部材５０は、ナット部材３０に取り付けられる被覆部５１と、ナット部材３０と回路基板２５を電気的に接続する接続部５２と、接地する接地部５３とを有する。 As shown in FIG. 9, the sheet metal member 50 electrically connects the nut member 30, which is a metal member to which the antenna member 26 is fixed and is electrically connected, and the circuit board 25, and the circuit board 25. It is a member for grounding etc.
As shown in FIG. 10A, the sheet metal member 50 includes a covering portion 51 attached to the nut member 30, a connection portion 52 for electrically connecting the nut member 30 and the circuit board 25, and a grounding portion 53 for grounding. Have

　被覆部５１は、鍔部３２の天面３２２の少なくとも一部を覆う天板５１１と、天板５１１から折曲げ形成されて、鍔部３２の凹部３６に嵌合して位置決めおよび固定するための一対の脚部５１２を有する。
　なお、段差部３５を凹部３６と同様に形成することにより、脚部５１２を段差部３５に嵌合することもできる。これにより、ナット部材３０の組み込み時に方向規制がなくなるので、組み立て効率の向上を図ることができる。 The covering portion 51 is formed by bending the top plate 511 that covers at least a part of the top surface 322 of the collar portion 32 and the top plate 511, and is fitted to the concave portion 36 of the collar portion 32 for positioning and fixing. A pair of legs 512 is provided.
Note that the leg portion 512 can be fitted to the stepped portion 35 by forming the stepped portion 35 in the same manner as the recessed portion 36. Thereby, since the direction restriction is eliminated when the nut member 30 is assembled, the assembly efficiency can be improved.

　脚部５１２の少なくとも一つは、下端部から上方へＵ字状に折り返されて、接地部５３が形成されている。接地部５３は、先端（上端）が外側へ開くように形成されており、ばね状に形成されている。図１０（Ｂ）に示すように、接地部５３は、ナット部材３０の鍔部３２の側面３２３に対向する位置にあり、鍔部３２の側面３２３の近傍において接地する（図１１参照）。
　図１０（Ｂ）に示すように、板金部材５０は、鍔部３２の天面３２２に板金部材５０の板厚Ｔを加えた位置Ｐよりも上方に突出しないように設けられる。
　これにより、図１１に示すように、板金部材５０がカバー２２側に当接しないので、カバー２２の取付けを阻害しない。 At least one of the leg portions 512 is folded upward in a U shape from the lower end portion to form a grounding portion 53. The grounding portion 53 is formed so that the tip (upper end) is opened outward, and is formed in a spring shape. As shown in FIG. 10B, the grounding portion 53 is at a position facing the side surface 323 of the flange portion 32 of the nut member 30, and is grounded in the vicinity of the side surface 323 of the flange portion 32 (see FIG. 11).
As shown in FIG. 10B, the sheet metal member 50 is provided so as not to protrude upward from a position P where the sheet thickness T of the sheet metal member 50 is added to the top surface 322 of the flange portion 32.
As a result, as shown in FIG. 11, the sheet metal member 50 does not abut against the cover 22 side, so that attachment of the cover 22 is not hindered.

　以上、説明した本発明に係る第２実施形態の電子機器１０Ｂによれば、板金部材５０は、鍔部３２の一対の凹部３６に係合し、かつ、鍔部３２の天面３２２の一部を覆う被覆部５１を有する。このため、板金部材５０をナット部材３０の所定位置に確実に取り付けることができる。
　また、板金部材５０には、被覆部５１に連結されて、鍔部３２の側面３２３の近傍において接地する接地部５３を設けたので、ナット部材３０の軸方向寸法を従来よりも小さくすることができ、電子機器１０Ｂの小型化・薄型化を図ることができる。 As described above, according to the electronic apparatus 10B according to the second embodiment of the present invention described above, the sheet metal member 50 is engaged with the pair of concave portions 36 of the flange portion 32 and a part of the top surface 322 of the flange portion 32. A covering portion 51 is provided. For this reason, the sheet metal member 50 can be reliably attached to the predetermined position of the nut member 30.
Further, since the sheet metal member 50 is provided with the grounding portion 53 that is connected to the covering portion 51 and grounds in the vicinity of the side surface 323 of the flange portion 32, the axial dimension of the nut member 30 can be made smaller than before. Thus, the electronic device 10B can be reduced in size and thickness.

　なお、本発明の電子機器は、前述した各実施形態に限定されるものでなく、適宜な変形，改良等が可能である。
　例えば、前述した各実施形態においては、ナット部材３０の鍔部３２に、径方向内側に凹んだ段差部３５と凹部３６とを設けた場合を例示した。これに代わって、図１２に示すナット部材３０Ｂのように、鍔部３２Ｂに、段差部として径方向外側へ突出する一対の突出部３８，３８を設けることができる。そして、案内部４３として、柱状の案内柱４３１と、逆Ｌ字形状の係止部４３２とを設ける。 The electronic device of the present invention is not limited to the above-described embodiments, and appropriate modifications and improvements can be made.
For example, in each embodiment mentioned above, the case where the level | step-difference part 35 and the recessed part 36 which were dented in radial inside were provided in the collar part 32 of the nut member 30 was illustrated. Instead, like the nut member 30B shown in FIG. 12, the flange portion 32B can be provided with a pair of projecting portions 38, 38 projecting radially outward as stepped portions. And as the guide part 43, the column-shaped guide pillar 431 and the latching | locking part 432 of an inverted L shape are provided.

　このように構成することにより、金属部材であるナット部材３０Ｂを取り付ける際には、まず、突出部３８を案内柱４３１に沿って矢印Ａ方向に挿入する。そして、壁部４０の上面４０１に沿って突出部３８を矢印Ｂ方向へ移動させて突出部３８を係止部４３２で係止する。
