Description

固定構造及び固定方法Fixing structure and fixing method
　本発明は、固定構造に関し、例えば、車両用灯具等の取付部に音発生装置を固定する固定構造に関する。 The present invention relates to a fixing structure, and for example, to a fixing structure for fixing a sound generating device to a mounting portion of a vehicle lamp or the like.
　ハイブリッド車や電気自動車のようにモータを走行駆動源とする車両では、低速時におけるモータ音が静粛であるため他車両や歩行者が自車両に気づき難い。そこで、モータ音とは別の疑似音を発生させ、この疑似音を他車両や歩行者に対する警告音とする技術が提案されている。 In vehicles such as hybrid cars and electric cars that use a motor as a drive source, the motor noise is quiet at low speeds, making it difficult for other vehicles and pedestrians to notice the vehicle. Therefore, a technique has been proposed in which a pseudo sound different from the motor sound is generated and the pseudo sound is used as a warning sound for other vehicles and pedestrians.
　例えば、光源と、車両用灯具を構成するアウタレンズに固定され、電気信号を受けて振動によりアウタレンズを発音させる振動子と、を備える車両用灯具が考案されている（特許文献１）。 For example, a vehicle lamp has been devised that includes a light source and a vibrator that is fixed to an outer lens constituting the vehicle lamp and that receives an electric signal and causes the outer lens to generate sound by vibration (Patent Document 1).
特開２０１３－２４１１５６号公報Japanese Patent Application Publication No. 2013-241156
　上述の振動子は、ボディの外縁部の２箇所に形成された、径方向外側に向かって突出するタブ片を有している。そして、そのタブ片に形成された挿通穴に挿通されたネジにより、車両用灯具の一部であるアウタレンズやランプボディの外側に振動子が固定されている。また、上述の振動子は、駆動コイルに交流電流を印加するためのハーネスがボディを貫通して灯室の外部に引き出されている。 The above-mentioned vibrator has tab pieces that are formed at two locations on the outer edge of the body and protrude outward in the radial direction. The vibrator is fixed to the outside of the outer lens or lamp body, which is a part of the vehicle lamp, by a screw inserted into an insertion hole formed in the tab piece. Further, in the above-mentioned vibrator, a harness for applying alternating current to the drive coil passes through the body and is drawn out to the outside of the lamp chamber.
　そのため、ハーネスの防水性を考慮すれば、音を発するユニットへの電源供給や信号通信を担うハーネスを車両用灯具の内側に配置することが一案である。その場合、ハーネス端部のコネクタとユニットを接続した状態でユニットを車両用灯具に固定する新たな固定構造が求められている。 Therefore, considering the waterproofness of the harness, one idea is to place the harness responsible for supplying power to the unit that emits sound and for signal communication inside the vehicle lamp. In this case, there is a need for a new fixing structure that fixes the unit to the vehicle lamp while the unit is connected to the connector at the end of the harness.
　本発明はこうした状況に鑑みてなされたものであり、その例示的な目的の一つは、取付部に音発生装置を固定する新たな固定構造を提供することにある。 The present invention has been made in view of these circumstances, and one of its illustrative purposes is to provide a new fixing structure for fixing a sound generating device to a mounting portion.
　上記課題を解決するために、本発明のある態様の固定構造は、音発生装置と、音発生装置を所定の位置に取り付ける取付部と、音発生装置を保持した状態で、取付部に固定される保持部材と、音発生装置に接続されるワイヤーハーネスと、を備える。音発生装置は、ワイヤーハーネスのコネクタが接続される接続部を有する。取付部は、保持部材が固定される際に接続部に接続された状態のコネクタに当接する当接面を有している。 In order to solve the above problems, a fixing structure according to an aspect of the present invention includes a sound generator, a mounting part for mounting the sound generator in a predetermined position, and a fixing structure for fixing the sound generator to the mounting part while holding the sound generator. and a wire harness connected to the sound generating device. The sound generating device has a connection portion to which a connector of the wire harness is connected. The attachment part has a contact surface that comes into contact with the connector connected to the connection part when the holding member is fixed.
　この態様によると、音発生装置を所定の位置に取り付けた状態では、音発生装置の接続部に接続されたコネクタに取付部の当接面が当接することで、振動や接続不良によってコネクタが抜けることが抑制される。 According to this aspect, when the sound generating device is installed in a predetermined position, the contact surface of the mounting portion comes into contact with the connector connected to the connecting portion of the sound generating device, and the connector may come off due to vibration or poor connection. things are suppressed.
　保持部材は、取付部に対して回転動作で所定位置に固定されるように構成されていてもよい。これにより、保持部材を取付部に対して簡易に固定できる。 The holding member may be configured to be fixed at a predetermined position by rotation with respect to the mounting portion. Thereby, the holding member can be easily fixed to the mounting portion.
　当接面は、取付部の保持部材と対向する側に設けられており、保持部材の回転動作に伴いコネクタを接続部に向けて圧入するように構成された傾斜部を有してもよい。これにより、保持部材を取付部に固定する際にコネクタを接続部に向けて圧入できる。 The abutment surface is provided on the side of the attachment portion facing the holding member, and may have an inclined portion configured to press-fit the connector toward the connection portion as the holding member rotates. Thereby, when fixing the holding member to the attachment part, the connector can be press-fitted toward the connection part.
　傾斜部は、取付部に形成された円弧状のスリットの少なくとも片側に沿って設けられていてもよい。これにより、保持部材を取付部に対して回転動作する際に、傾斜部がコネクタを接続部に向けて徐々に圧入できる。 The inclined portion may be provided along at least one side of the arcuate slit formed in the attachment portion. Thereby, when the holding member is rotated with respect to the attachment part, the inclined part can gradually press fit the connector toward the connection part.
　取付部は、傾斜部の高さが低い側の端部に形成された、コネクタが通る貫通孔を有してもよい。スリットは、貫通孔と繋がっており、ワイヤーハーネスのケーブルが通り、かつコネクタが通らない形状であってもよい。これにより、コネクタが貫通孔を通った状態で保持部材を取付部に対して回転した後は、コネクタがスリットに引っかかることで、保持部材が取付部から抜けなくなる。 The attachment part may have a through hole formed at the lower end of the inclined part, through which the connector passes. The slit may be connected to the through hole, and may have a shape through which the cable of the wire harness can pass, but not through which the connector can pass. As a result, after the holding member is rotated relative to the mounting portion with the connector passing through the through hole, the connector is caught in the slit, and the holding member cannot be removed from the mounting portion.
　本発明の別の態様は、固定方法である。この方法は、音発生装置を所定の位置に取り付ける取付部に該音発生装置を固定する固定方法であって、取付部に形成された貫通孔から該取付部の外側に引き出されたワイヤーハーネスのコネクタを、音発生装置の接続部に接続する接続工程と、コネクタが接続された音発生装置を保持した保持部材を、取付部に固定する固定工程と、を含む。固定工程は、接続部に接続された状態のコネクタを、取付部が有する当接面に当接させる工程と、当接面に当接したコネクタを保持部材の回転動作に伴い接続部に向けて圧入する工程と、を有する。 Another aspect of the present invention is a fixing method. This method is a fixing method in which a sound generator is fixed to a mounting part that is attached to a predetermined position, and a wire harness is pulled out from a through hole formed in the mounting part to the outside of the mounting part. The method includes a connecting step of connecting the connector to a connecting portion of the sound generating device, and a fixing step of fixing a holding member holding the sound generating device to which the connector is connected to the mounting portion. The fixing process includes the process of bringing the connector connected to the connection part into contact with the contact surface of the mounting part, and the process of moving the connector that has come into contact with the contact surface toward the connection part as the holding member rotates. and a step of press-fitting.
　この態様によると、音発生装置を所定の位置に取り付けた状態では、音発生装置の接続部に接続された状態のコネクタに取付部の当接面が当接することで、振動や接続不良によってコネクタが抜けることが抑制される。 According to this aspect, when the sound generating device is installed in a predetermined position, the contact surface of the mounting portion comes into contact with the connector connected to the connecting portion of the sound generating device, and the connector may be damaged due to vibration or poor connection. is suppressed from coming off.
　以上の構成要素の任意の組合せ、本発明の表現を製造方法、灯具や照明などの装置、発光モジュール、光源などの間で変換したものもまた、本発明の態様として有効である。 Arbitrary combinations of the above constituent elements and expressions of the present invention converted between manufacturing methods, devices such as lamps and lighting, light emitting modules, light sources, etc. are also effective as embodiments of the present invention.
　本発明によれば、簡易な作業で音発生装置への給電を実現できる。 According to the present invention, power supply to the sound generating device can be realized with a simple operation.

　（第１の実施の形態）
　図１は、第１の実施の形態に係る車両用灯具の概略構成を示す縦断面図である。なお、図１は一部の部品を省略して図示している。図１に示す車両用灯具としての車両用前照灯１０は、不図示の光源から出射された光が車両前方へ向けて透過するように配置されるアウタレンズ１２と、光源と車両本体とを隔てる隔壁としてのランプボディ１４と、を備える。アウタレンズ１２は、ランプボディ１４の車両前方側の開口を塞ぐように、ランプボディ１４と一体化され、光源が配置される灯室１６を構成する。 (First embodiment)
FIG. 1 is a longitudinal sectional view showing a schematic configuration of a vehicle lamp according to a first embodiment. Note that FIG. 1 shows some parts omitted. A vehicle headlamp 10 as a vehicle lamp shown in FIG. 1 includes an outer lens 12 disposed so that light emitted from a light source (not shown) is transmitted toward the front of the vehicle, and an outer lens 12 that separates the light source from the vehicle body. A lamp body 14 as a partition wall is provided. The outer lens 12 is integrated with the lamp body 14 so as to close the opening of the lamp body 14 on the vehicle front side, and forms a lamp chamber 16 in which a light source is arranged.
　このように構成された車両用前照灯１０は、車両フード１８及びバンパ２０の間の空間に配置されている。本実施の形態に係る車両用前照灯１０は、ランプボディ１４の底部１４ａの灯具外側に、車両周囲の他車両や歩行者に対する警告音を発生する音発生構造２２が設けられている。 The vehicle headlamp 10 configured in this manner is arranged in a space between the vehicle hood 18 and the bumper 20. In the vehicle headlamp 10 according to the present embodiment, a sound generating structure 22 that generates a warning sound for other vehicles and pedestrians around the vehicle is provided on the outside of the lamp body 14 at the bottom 14 a of the lamp body 14 .

FIG. 3 is a top view of the fixing structure according to the first embodiment. FIG. 4 is a side view of the fixing structure shown in FIG. 3 viewed from direction B. FIG. 5 is a top view of the fixing structure shown in FIG. 3 with illustration of the mounting portion omitted. FIG. 6 is a side view of the fixing structure shown in FIG. 5 viewed from direction C. FIG. 7 is a cross-sectional view taken along line AA of the cross-sectional structure shown in FIG. The sound generating structure 22 shown in FIG. 1 also serves as a fixed structure according to the present embodiment, and hereinafter, the sound generating structure 22 will be described as a fixed structure 23. Further, although a fixing structure fixed to a vehicle lamp will be described below as an example, a fixing structure fixed to a component other than a vehicle lamp may be used.
　図２乃至図７に示すように、固定構造２３は、音発生装置の一種であるスピーカユニット２４と、スピーカユニット２４を車両用灯具の所定の位置に取り付ける取付部２６と、スピーカユニット２４を保持した状態で、取付部２６に固定される保持部材としてのカバー２８と、スピーカユニット２４に接続されるワイヤーハーネス３０と、を備える。ワイヤーハーネス３０は、コネクタ３０ａと、コネクタ３０ａに一端が結合されているケーブル３０ｂと、を有する。 As shown in FIGS. 2 to 7, the fixed structure 23 holds a speaker unit 24, which is a type of sound generating device, a mounting portion 26 for attaching the speaker unit 24 to a predetermined position of a vehicle lamp, and a speaker unit 24. A cover 28 as a holding member that is fixed to the mounting portion 26 in this state, and a wire harness 30 that is connected to the speaker unit 24 are provided. The wire harness 30 includes a connector 30a and a cable 30b whose one end is coupled to the connector 30a.
　ランプボディ１４の外側に設けられたスピーカユニット２４は、音Ｓを発する前面２４ａが車両外部ＥＸへ向くようにスピーカボディ３２中央の所定位置に固定されている。スピーカユニット２４は、音を発するものであればよく、例えば、ボイスコイルとマグネットにより振動板を振動させることで音を発する構造であってもよい。本実施の形態に係るスピーカユニット２４は、電気信号を振動に変換する磁気回路（不図示）と、磁気回路の振動が伝わる円板状の振動板２４ｂと、を有する。 The speaker unit 24 provided outside the lamp body 14 is fixed at a predetermined position in the center of the speaker body 32 so that the front surface 24a that emits the sound S faces toward the vehicle exterior EX. The speaker unit 24 may be any device that emits sound; for example, it may have a structure that emits sound by vibrating a diaphragm using a voice coil and a magnet. The speaker unit 24 according to this embodiment includes a magnetic circuit (not shown) that converts an electric signal into vibration, and a disc-shaped diaphragm 24b that transmits the vibration of the magnetic circuit.
　スピーカボディ３２は、ワイヤーハーネス３０のコネクタ３０ａが接続される接続部３２ａを有する。また、本実施の形態に係る取付部２６は、車両用前照灯１０を構成する灯具部品としてのランプボディ１４の一部（底部１４ａ）である。灯具部品としては、ランプボディ１４そのものに限らず、ランプボディ１４と一体の他部品や、ランプボディ１４と連結される他部品であってもよい。取付部２６は、カバー２８と対向する側に、カバー２８が固定される際に接続部３２ａに接続された状態のコネクタ３０ａに当接する当接面２６ａを有している。これにより、スピーカユニット２４を所定の位置に取り付けた状態では、スピーカユニット２４の接続部３２ａに接続されたコネクタ３０ａに取付部２６の当接面２６ａが当接することで、振動や接続不良によってコネクタ３０ａが抜けることが抑制される。また、仮にカバー２８を取付部２６に固定する際に、コネクタ３０ａが半嵌合状態で接続部３２ａから多少浮いた状態であった場合、当接面２６ａがコネクタ３０ａと干渉することで取付部２６へのカバー２８の組付けが困難となり、半嵌合状態で組付けが完了することを防止できる。 The speaker body 32 has a connecting portion 32a to which the connector 30a of the wire harness 30 is connected. Further, the mounting portion 26 according to the present embodiment is a part (bottom portion 14a) of the lamp body 14 as a lamp component that constitutes the vehicle headlamp 10. The lamp parts are not limited to the lamp body 14 itself, but may be other parts integrated with the lamp body 14 or other parts connected to the lamp body 14. The attachment part 26 has a contact surface 26a on the side facing the cover 28, which comes into contact with the connector 30a connected to the connection part 32a when the cover 28 is fixed. As a result, when the speaker unit 24 is installed in a predetermined position, the contact surface 26a of the mounting part 26 comes into contact with the connector 30a connected to the connection part 32a of the speaker unit 24, and vibration or poor connection may cause the connector to 30a is prevented from coming off. Moreover, when fixing the cover 28 to the mounting part 26, if the connector 30a is in a half-fitted state and is slightly lifted from the connecting part 32a, the contact surface 26a may interfere with the connector 30a, causing the mounting part It becomes difficult to assemble the cover 28 to the cover 26, and it is possible to prevent the assembly from being completed in a half-fitted state.
　スピーカボディ３２は、円筒状の筐体３２ｂを有し、筐体３２ｂの車両外部側の開口３２ｃを閉塞するように振動板２４ｂを保持している。これにより、水や埃が筐体３２ｂを通って車両内部へ入り込むことを防止できる。 The speaker body 32 has a cylindrical housing 32b, and holds a diaphragm 24b so as to close an opening 32c of the housing 32b on the vehicle exterior side. This can prevent water and dust from entering the vehicle interior through the housing 32b.
　また、固定構造２３は、振動板２４ｂの前面２４ａを覆うカバー２８を更に備えている。カバー２８は、スピーカユニット２４が直接外部に露出しないように保護するためのものであり、スピーカユニット２４の破損や汚損が低減される。また、カバー２８は、振動板２４ｂから出た音が外部へ伝わりやすいように穴やスリット２９が形成されている。また、カバー２８は、取付部２６に固定される際に、取付部２６と結合する結合部２８ａを有する。 Furthermore, the fixed structure 23 further includes a cover 28 that covers the front surface 24a of the diaphragm 24b. The cover 28 is for protecting the speaker unit 24 from being directly exposed to the outside, thereby reducing damage and staining of the speaker unit 24. Further, the cover 28 is formed with holes or slits 29 so that the sound emitted from the diaphragm 24b can be easily transmitted to the outside. Further, the cover 28 has a coupling portion 28a that is coupled to the mounting portion 26 when the cover 28 is fixed to the mounting portion 26.
　本実施の形態に係る結合部２８ａは、カバー２８の一部が加工されたスナップフィットやローテーションフィックスである。スナップフィットとは、例えば、材料の弾性を利用してはめ込むことにより固定する方式の一つである。ローテーションフィックスとは、相対的な回転動作により一方の部品が他方の部品を押す力が増すことで最終的に互いが固定される方式の一つである。 The coupling portion 28a according to the present embodiment is a snap fit or rotation fix in which a part of the cover 28 is processed. Snap fit is one of the methods of fixing by fitting, for example, using the elasticity of the material. Rotation fixing is a method in which the force of one part pushing the other part increases through relative rotational movement, thereby ultimately fixing them together.
　本実施の形態に係るカバー２８は、筐体２８ｂの車両用灯具側の開口２８ｃの縁部２８ｄにローテーションフィックスである結合部２８ａが設けられている。これにより、スピーカユニット２４は、カバー２８を介して簡易にランプボディ１４に固定できる。 In the cover 28 according to the present embodiment, a coupling portion 28a, which is a rotation fix, is provided at the edge 28d of the opening 28c on the vehicle lamp side of the housing 28b. Thereby, the speaker unit 24 can be easily fixed to the lamp body 14 via the cover 28.
　カバー２８は、筐体２８ｂの外周部の環状のフランジ部２８ｅにＯリング３４が装着されている。Ｏリング３４は、取付部２６とカバー２８との間を封止する。これにより、接着剤等を用いずに取付部２６とカバー２８との間から水や埃が車両内部へ入り込むことを防止できる。 The cover 28 has an O-ring 34 attached to an annular flange 28e on the outer periphery of the housing 28b. The O-ring 34 seals between the mounting portion 26 and the cover 28. This makes it possible to prevent water and dust from entering the vehicle from between the mounting portion 26 and the cover 28 without using adhesive or the like.
　次に、カバー２８をランプボディ１４の底部１４ａに取り付けて固定する方法の一例について説明する。図５等に示すように、本実施の形態に係る固定構造２３は、縁部２８ｄの３箇所に等間隔で結合部２８ａが設けられている。結合部２８ａは、縁部２８ｄから径方向外側に張り出したフランジ部２８ｆを有する。そして、図２や図３に示す取付部２６に形成された３箇所の開口２６ｂにフランジ部２８ｆの位置Ｐ１を合わせ、結合部２８ａを底部１４ａから灯室１６側に向けて突き出す。 Next, an example of a method for attaching and fixing the cover 28 to the bottom 14a of the lamp body 14 will be described. As shown in FIG. 5 and the like, in the fixing structure 23 according to the present embodiment, coupling portions 28a are provided at three locations on the edge 28d at equal intervals. The coupling portion 28a has a flange portion 28f that projects outward in the radial direction from the edge portion 28d. Then, the position P1 of the flange portion 28f is aligned with the three openings 26b formed in the mounting portion 26 shown in FIGS. 2 and 3, and the connecting portion 28a is projected from the bottom portion 14a toward the lamp chamber 16 side.
　図４に示すように、フランジ部２８ｆの裏側には傾斜部２８ｇが設けられている。そのため、結合部２８ａが灯室１６側に突き出した状態で底部１４ａに対してカバー２８を回転させると、傾斜部２８ｇが底部１４ａの内面１４ｃに当接しながら移動することで結合部２８ａが灯室１６側に徐々に引き込まれる。そして、結合部２８ａが位置Ｐ２まで移動することで、傾斜部２８ｇの頂点で底部１４ａの内面１４ｃがしっかり押圧され、カバー２８が底部１４ａに対してしっかり固定される。つまり、カバー２８は、ランプボディ１４に対して簡易な回転動作で所定位置に固定される。これにより、ネジを用いずにスピーカユニット２４を車両用前照灯１０に固定できる。 As shown in FIG. 4, an inclined portion 28g is provided on the back side of the flange portion 28f. Therefore, when the cover 28 is rotated with respect to the bottom part 14a with the joint part 28a protruding toward the lamp chamber 16, the inclined part 28g moves while coming into contact with the inner surface 14c of the bottom part 14a, so that the joint part 28a moves into the lamp chamber. It is gradually drawn to the 16 side. Then, by moving the coupling portion 28a to the position P2, the inner surface 14c of the bottom portion 14a is firmly pressed at the apex of the inclined portion 28g, and the cover 28 is firmly fixed to the bottom portion 14a. That is, the cover 28 is fixed at a predetermined position with respect to the lamp body 14 by a simple rotational movement. Thereby, the speaker unit 24 can be fixed to the vehicle headlamp 10 without using screws.
　以上のように、本実施の形態に係る固定方法は、スピーカユニット２４を車両や車両用灯具の所定の位置に取り付ける取付部２６にスピーカユニット２４を固定する方法である。そして、図３に示す取付部２６に形成された貫通孔２６ｃから取付部２６の外側（図３における紙面の裏側）に引き出されたワイヤーハーネス３０のコネクタ３０ａを、スピーカユニット２４の接続部３２ａに接続する。次に、コネクタ３０ａが接続されたスピーカユニット２４を保持したカバー２８を、前述の方法で取付部２６に固定する。これにより、スピーカユニット２４を所定の位置に取り付けた状態では、図７に示すように、スピーカユニット２４の接続部３２ａに接続された状態のコネクタ３０ａに取付部２６の当接面２６ａが上から当接することで、振動や接続不良によってコネクタ３０ａが接続部３２ａから抜けることが抑制される。 As described above, the fixing method according to the present embodiment is a method of fixing the speaker unit 24 to the mounting portion 26 that attaches the speaker unit 24 to a predetermined position of a vehicle or a vehicle lamp. Then, the connector 30a of the wire harness 30 pulled out from the through hole 26c formed in the mounting part 26 shown in FIG. Connecting. Next, the cover 28 holding the speaker unit 24 to which the connector 30a is connected is fixed to the mounting portion 26 by the method described above. As a result, when the speaker unit 24 is attached to a predetermined position, as shown in FIG. By making contact, the connector 30a is prevented from coming off from the connecting portion 32a due to vibration or poor connection.

FIG. 8 is a perspective view of the fixing structure according to the second embodiment. FIG. 9 is a perspective view of the mounting portion in the fixing structure shown in FIG. 8, viewed from the back side. FIG. 10 is a DD cross-sectional view of the fixing structure shown in FIG. 8. In the following description, the same components as those in the first embodiment are given the same reference numerals and names, and the description will be omitted as appropriate.
　図８乃至図１０に示すように、固定構造３６は、スピーカユニット２４と、スピーカユニット２４を車両用灯具の所定の位置に取り付ける取付部３８と、カバー２８と、スピーカユニット２４に接続されるワイヤーハーネス３０と、を備える。 As shown in FIGS. 8 to 10, the fixing structure 36 includes the speaker unit 24, a mounting portion 38 for attaching the speaker unit 24 to a predetermined position of the vehicle lamp, a cover 28, and a wire connected to the speaker unit 24. A harness 30 is provided.
　スピーカボディ３２は、ワイヤーハーネス３０のコネクタ３０ａが接続される接続部３２ａを有する。また、本実施の形態に係る取付部３８は、車両用前照灯１０を構成する灯具部品としてのランプボディ１４の一部（底部１４ａ）である。取付部３８は、カバー２８が固定される際に接続部３２ａに接続された状態のコネクタ３０ａに当接する当接面３８ａを有している。これにより、スピーカユニット２４を所定の位置に取り付けた状態では、スピーカユニット２４の接続部３２ａに接続されたコネクタ３０ａに取付部３８の当接面３８ａが当接することで、振動や接続不良によってコネクタ３０ａが抜けることが抑制される。 The speaker body 32 has a connecting portion 32a to which the connector 30a of the wire harness 30 is connected. Further, the mounting portion 38 according to the present embodiment is a part (bottom portion 14a) of the lamp body 14 as a lamp component that constitutes the vehicle headlamp 10. The attachment part 38 has a contact surface 38a that comes into contact with the connector 30a connected to the connection part 32a when the cover 28 is fixed. As a result, when the speaker unit 24 is installed in a predetermined position, the contact surface 38a of the mounting part 38 comes into contact with the connector 30a connected to the connection part 32a of the speaker unit 24, and vibration or poor connection may cause the connector to 30a is prevented from coming off.
　本実施の形態に係る当接面３８ａは、取付部３８のカバー２８と対向する側に設けられており、カバー２８の回転動作に伴いコネクタ３０ａを接続部３２ａに向けて圧入するように構成された傾斜部３８ｂを有している。傾斜部３８ｂは、取付部３８の裏面３８ｃからの高さＨ（図１０参照）が貫通孔３８ｄから円弧状のスリット３８ｅの先端に向かって徐々に大きくなる部分である。これにより、カバー２８を取付部３８に回転動作で固定する際に、コネクタ３０ａが半嵌合状態で接続部３２ａから多少浮いた状態であっても、コネクタ３０ａを接続部３２ａに向けて徐々に圧入できる。 The contact surface 38a according to the present embodiment is provided on the side of the mounting portion 38 facing the cover 28, and is configured to press-fit the connector 30a toward the connection portion 32a as the cover 28 rotates. It has a sloped portion 38b. The inclined portion 38b is a portion in which the height H (see FIG. 10) of the mounting portion 38 from the back surface 38c gradually increases from the through hole 38d toward the tip of the arc-shaped slit 38e. As a result, when fixing the cover 28 to the mounting part 38 by rotational movement, even if the connector 30a is in a half-fitted state and is slightly lifted from the connection part 32a, the connector 30a can be gradually moved toward the connection part 32a. Can be press-fitted.
　傾斜部３８ｂは、取付部３８に形成された円弧状のスリット３８ｅの両側に設けられている。これにより、カバー２８を取付部３８に対して回転動作する際に、傾斜部３８ｂがコネクタ３０ａを接続部３２ａに向けて徐々に圧入できる。なお、傾斜部３８ｂは、スリット３８ｅの少なくとも片側に沿って設けられていてもよい。 The inclined portions 38b are provided on both sides of the arc-shaped slit 38e formed in the attachment portion 38. Thereby, when the cover 28 is rotated with respect to the mounting portion 38, the inclined portion 38b can gradually press fit the connector 30a toward the connecting portion 32a. Note that the inclined portion 38b may be provided along at least one side of the slit 38e.
　取付部３８は、傾斜部３８ｂの高さＨが低い側の端部に形成された、コネクタが通る貫通孔３８ｄを有している。また、スリット３８ｅは、貫通孔３８ｄと繋がっており、ワイヤーハーネス３０のケーブル３０ｂが通り、かつコネクタ３０ａが通らない形状である。これにより、コネクタ３０ａが貫通孔３８ｄを通った状態でカバー２８を取付部３８に対して回転した後は、コネクタ３０ａがスリット３８ｅに引っかかることで、カバー２８が取付部３８から抜けなくなる。 The mounting portion 38 has a through hole 38d formed at the end of the inclined portion 38b on the side where the height H is lower, through which the connector passes. Further, the slit 38e is connected to the through hole 38d, and has a shape through which the cable 30b of the wire harness 30 passes, but not through which the connector 30a passes. As a result, after the cover 28 is rotated relative to the mounting portion 38 with the connector 30a passing through the through hole 38d, the cover 28 cannot be removed from the mounting portion 38 because the connector 30a is caught in the slit 38e.
　（第３の実施の形態）
　図１１は、第３の実施の形態に係る固定構造の斜視図である。図１２は、図１１に示す固定構造の上面図である。図１３は、図１１に示す固定構造のＥ－Ｅ断面図である。なお、以下の説明では、前述の各実施の形態と同様の構成には同じ符号や名称を付して説明を適宜省略する。 (Third embodiment)
FIG. 11 is a perspective view of the fixing structure according to the third embodiment. FIG. 12 is a top view of the fixing structure shown in FIG. 11. FIG. 13 is a sectional view taken along line EE of the fixing structure shown in FIG. In the following description, the same components as in each of the above-described embodiments will be given the same reference numerals and names, and the description will be omitted as appropriate.
　例えば、第１の実施の形態における固定構造２３では、回転動作によってカバー２８を取付部２６に固定する。そのため、回転動作による固定の際に、カバー２８の結合部２８ａと取付部２６との間にケーブル３０ｂが噛み込まれるおそれがある。そこで、本実施の形態に係る固定構造は、ケーブルの噛み込みを抑制する構成を採用している。 For example, in the fixing structure 23 in the first embodiment, the cover 28 is fixed to the mounting portion 26 by rotation. Therefore, there is a risk that the cable 30b may be caught between the coupling portion 28a of the cover 28 and the attachment portion 26 when the cover 28 is fixed by rotational movement. Therefore, the fixing structure according to the present embodiment employs a configuration that suppresses the cable from being caught.
　図１１乃至１３に示すように、固定構造４０は、スピーカユニット２４と、スピーカユニット２４を車両用灯具の所定の位置に取り付ける取付部４２と、スピーカユニット２４を保持した状態で、取付部４２に固定されるカバー２８と、スピーカユニット２４に接続されるワイヤーハーネス３０と、を備える。 As shown in FIGS. 11 to 13, the fixing structure 40 includes a speaker unit 24, a mounting portion 42 for mounting the speaker unit 24 in a predetermined position of a vehicle lamp, and a mounting portion 42 for attaching the speaker unit 24 to the mounting portion 42 while holding the speaker unit 24. It includes a cover 28 that is fixed, and a wire harness 30 that is connected to the speaker unit 24.
　ランプボディ１４の外側に設けられたスピーカユニット２４は、音Ｓを発する前面２４ａが車両外部ＥＸへ向くようにスピーカボディ３２中央の所定位置に固定されている。本実施の形態に係るスピーカユニット２４は、電気信号を振動に変換する磁気回路２４ｃと、磁気回路２４ｃの振動が伝わる円板状の振動板２４ｂと、を有する。 The speaker unit 24 provided outside the lamp body 14 is fixed at a predetermined position in the center of the speaker body 32 so that the front surface 24a that emits the sound S faces toward the vehicle exterior EX. The speaker unit 24 according to this embodiment includes a magnetic circuit 24c that converts an electric signal into vibration, and a disc-shaped diaphragm 24b that transmits the vibration of the magnetic circuit 24c.
　スピーカボディ３２は、ワイヤーハーネス３０のコネクタ３０ａが接続される接続部３２ａと、円筒状の筐体３２ｂとを有し、筐体３２ｂの車両外部側の開口３２ｃを閉塞するように振動板２４ｂを保持している。これにより、水や埃が筐体３２ｂを通って車両内部へ入り込むことを防止できる。また、本実施の形態に係るスピーカボディ３２は、結合部２８ａと取付部４２との嵌合部近傍へのケーブル３０ｂの接近を邪魔する邪魔部３２ｄを更に有する。なお、邪魔部３２ｄは、コネクタ３０ａからケーブル３０ｂが延びる方向に１箇所設けていてもよいし、複数の結合部２８ａごとに設けていてもよい。 The speaker body 32 has a connecting portion 32a to which the connector 30a of the wire harness 30 is connected, and a cylindrical housing 32b. keeping. This can prevent water and dust from entering the vehicle interior through the housing 32b. Furthermore, the speaker body 32 according to the present embodiment further includes a blocking portion 32d that prevents the cable 30b from approaching the vicinity of the fitting portion between the coupling portion 28a and the attachment portion 42. Note that the baffle portion 32d may be provided at one location in the direction in which the cable 30b extends from the connector 30a, or may be provided for each of the plurality of coupling portions 28a.
　邪魔部３２ｄは、取付部４２に形成されている円弧状のスリット４２ａから灯室１６側に突き出す円弧状のリブであり、結合部２８ａとコネクタ３０ａとの間に設けられている。邪魔部３２ｄの取付部４２からの突き出し量は、結合部２８ａの取付部４２からの突き出し量より大きい。したがって、取付部４２にカバー２８を挿入する際に、ケーブル３０ｂを持ち上げることができる。また、円弧状の邪魔部３２ｄの中心角αは、結合部２８ａの中心角βよりも大きい。そのため、コネクタ３０ａからみて結合部２８ａが邪魔部３２ｄによって隠れる。したがって、仮にケーブル３０ｂが結合部２８ａに向かって延びている場合であっても、ケーブル３０ｂと結合部２８ａとが触れにくくなり、カバー２８の結合部２８ａと取付部４２との間にケーブル３０ｂが噛み込まれることを防止できる。 The baffle portion 32d is an arc-shaped rib that protrudes toward the lamp chamber 16 from an arc-shaped slit 42a formed in the mounting portion 42, and is provided between the coupling portion 28a and the connector 30a. The amount by which the baffle portion 32d protrudes from the attachment portion 42 is greater than the amount by which the coupling portion 28a protrudes from the attachment portion 42. Therefore, when inserting the cover 28 into the attachment portion 42, the cable 30b can be lifted. Further, the central angle α of the arc-shaped baffle portion 32d is larger than the central angle β of the joint portion 28a. Therefore, the coupling portion 28a is hidden by the obstructing portion 32d when viewed from the connector 30a. Therefore, even if the cable 30b extends toward the coupling part 28a, the cable 30b and the coupling part 28a are difficult to touch, and the cable 30b is between the coupling part 28a of the cover 28 and the attachment part 42. It can prevent you from getting bitten.
　本実施の形態に係る邪魔部３２ｄは、取付部４２にカバー２８を固定する際の回転方向Ｒ（図１１参照）の先端側に傾斜部３２ｅが形成されている。傾斜部３２ｅがあることで、取付部４２の表面にケーブル３０ｂが存在していても、カバー２８の回転動作に伴いケーブル３０ｂをスムーズに邪魔部３２ｄの上に誘導することができる。 The obstructing portion 32d according to the present embodiment has an inclined portion 32e formed on the distal end side in the rotation direction R (see FIG. 11) when fixing the cover 28 to the mounting portion 42. Because of the inclined portion 32e, even if the cable 30b is present on the surface of the attachment portion 42, the cable 30b can be smoothly guided over the obstructing portion 32d as the cover 28 rotates.
　（第４の実施の形態）
　図１４は、第４の実施の形態に係る固定構造の斜視図である。なお、以下の説明では、前述の各実施の形態と同様の構成には同じ符号や名称を付して説明を適宜省略する。 (Fourth embodiment)

Specifically, the inclined portion 28h is formed in the connecting portion 28a that is farthest from the connector 30a among the three connecting portions 28a. The inclined portion 28h is formed on the distal end side in the rotation direction R of the coupling portion 28a. Further, a stopper 28k is formed on the rear end side of the coupling portion 28a in the rotation direction R to prevent the cable 30b guided onto the coupling portion 28a from falling onto the upper surface of the attachment portion 42 again.
　なお、傾斜部２８ｈは、全ての結合部２８ａに設けられていてもよいし、一つ又は一部の結合部に設けられていてもよい。また、ストッパー２８ｋは、全ての結合部２８ａに設けられていてもよいし、一つ又は一部の結合部に設けられていてもよい。あるいは、ストッパー２８ｋを設けなくてもよい。 Incidentally, the inclined portion 28h may be provided in all the coupling portions 28a, or may be provided in one or a part of the coupling portions. Further, the stopper 28k may be provided on all the joints 28a, or on one or some of the joints. Alternatively, the stopper 28k may not be provided.
