Description

本発明は、車両の室内等に使用される照明ユニットに関する。 The present invention relates to a lighting unit used in a vehicle interior or the like.

例えば、車両には、種々の場所(ドアカーテシー照明、足元照明、マップ照明、充電口照明等)に照明ユニットが設置される。そして、照明ユニットの取付構造にも種々の構造がある。例えば、発光面となるカバーが外部より目立たない位置に配置される照明ユニットでは、照明取付部材である車体パネルに取付穴を開口し、この取付穴に取付ける構造のものがある(特許文献1参照)。 For example, in a vehicle, lighting units are installed in various places (door curtsy lighting, foot lighting, map lighting, charging port lighting, etc.). And, there are various structures in the mounting structure of the lighting unit. For example, in a lighting unit in which a cover serving as a light emitting surface is arranged at a position inconspicuous from the outside, there is a structure in which a mounting hole is opened in a vehicle body panel which is a lighting mounting member and the cover is mounted in the mounting hole (see Patent Document 1). ).

特許文献1に開示された照明ユニットは、光源等を部品収容室に収容したハウジングと、部品収容室の開口を塞ぐようにしてハウジングに装着されたカバーとを有する。このカバーには、照明取付部材の取付穴に取付けできるカバー側取付部が設けられている。カバー側取付部は、弾性係止爪を有し、取付穴を中心としてカバー側取付部を回転させることで弾性係止爪が取付穴に係止される。 The lighting unit disclosed in Patent Document 1 has a housing in which a light source or the like is housed in a component housing chamber, and a cover mounted on the housing so as to close the opening of the component housing chamber. The cover is provided with a cover-side mounting portion that can be mounted in a mounting hole of the lighting mounting member. The cover-side mounting portion has an elastic locking claw, and the elastic locking claw is locked to the mounting hole by rotating the cover-side mounting portion around the mounting hole.

カバーの取付け作業時には、弾性係止爪を弾性変形させる必要がある等の理由によって、カバーには照明取付部材からの回転反力が作用するが、カバーがハウジングの外周を被っているため、ハウジングが変形せずに、カバーが脱落することがない。 When the cover is attached, a rotational reaction force from the lighting attachment member acts on the cover because the elastic locking claw needs to be elastically deformed. However, since the cover covers the outer periphery of the housing, the housing Does not deform and the cover does not fall off.

特開2001−243829号公報Japanese Unexamined Patent Publication No. 2001-243829

ところで、照明ユニットのコンパクト化のために、カバーがハウジングの外側を被う構造ではなく、例えば、カバーをハウジングの部品収容室の開口寸法と同じ寸法にしたいという要請がある(図24(c)のような構造)。カバーがハウジングより突出しないため、その分照明ユニットのコンパクト化が可能である。 By the way, in order to make the lighting unit compact, there is a request that the cover does not cover the outside of the housing, but for example, the cover should have the same size as the opening size of the component storage chamber of the housing (FIG. 24 (c)). Structure like). Since the cover does not protrude from the housing, the lighting unit can be made more compact.

しかし、このような構造にすると、カバーがハウジングを外側から拘束しないため、ハウジングが変形し易い構造となる。すると、照明ユニットを照明取付部材の取付穴に取り付ける際の回転反力によってハウジングが変形し、カバーがハウジングより外れる恐れがある。 However, with such a structure, the cover does not restrain the housing from the outside, so that the housing is easily deformed. Then, the housing may be deformed by the rotational reaction force when the lighting unit is attached to the mounting hole of the lighting mounting member, and the cover may come off from the housing.

そこで、本発明は、前記した課題を解決すべくなされたものであり、照明取付部材の取付穴に回転によって取付けする際に、カバーがハウジングから外れるのを極力防止できる照明ユニットを提供することを目的とする。 Therefore, the present invention has been made to solve the above-mentioned problems, and provides a lighting unit capable of preventing the cover from coming off from the housing as much as possible when the cover is mounted in the mounting hole of the lighting mounting member by rotation. The purpose.

本発明は、底壁と前記底壁より立設する一対の立設壁に囲まれた部品収容室を有し、前記部品収容室に光源と前記光源から外部間の回路を構成する回路体とを収容するハウジングと、
前記ハウジングにロック手段によって装着されて前記部品収容室の開口を塞ぎ、照明取付部材の取付穴に回転で取付けできるカバー側取付部を有するカバーとを備え、
前記ハウジングの一対の立設壁には変形規制用溝が設けられ、前記カバーには前記変形規制用溝に入り込む変形規制用リブが設けられたことを特徴とする照明ユニットである。
The present invention has a component accommodating chamber surrounded by a bottom wall and a pair of erecting walls erected from the bottom wall, and the component accommodating chamber includes a light source and a circuit body constituting a circuit between the light source and the outside. Housing and
It is provided with a cover which is attached to the housing by a locking means to close the opening of the component accommodating chamber and has a cover-side mounting portion which can be rotationally mounted in a mounting hole of a lighting mounting member.
The lighting unit is characterized in that a pair of vertical walls of the housing is provided with a deformation restricting groove, and the cover is provided with a deformation regulating rib that enters the deformation regulating groove.

本発明によれば、ハウジングを回転し、照明取付部材の取付穴に回転取付けする時には、ハウジングがカバーより回転反力を受けるが、回転反力を一対の立設壁の変形規制用溝の面で受けるため、回転反力が一対の立設壁を開く方向に作用せず、カバーがハウジングから外れるのを極力防止できる。 According to the present invention, when the housing is rotated and rotationally mounted in the mounting holes of the lighting mounting member, the housing receives a rotational reaction force from the cover, but the rotational reaction force is applied to the surface of the deformation control groove of the pair of standing walls. Therefore, the rotational reaction force does not act in the direction of opening the pair of standing walls, and the cover can be prevented from coming off from the housing as much as possible.

The installation procedure is as follows.

(インナー部材)
図11等に示すように、インナー部材60は、光を透過させる部材より形成されている。インナー部材60は、ハウジング10の部品収容室11の上面開口にほぼ隙間なく入り込むサイズに形成されている。インナー部材60には、部品収容室11に収容された状態で、発光ダイオード2の真上となる位置に周囲より一段高い円形部61が設けられている。インナー部材60には、一対のバスバー抜け防止肩面62が形成されている。インナー部材60が部品収容室11に収容された状態では、一対のバスバー抜け防止肩面62は、バスバー30の把持片部39のバスバー抜け側に位置する。
(Inner member)
As shown in FIG. 11 and the like, the inner member 60 is formed of a member that transmits light. The inner member 60 is formed in a size that allows the inner member 60 to enter the upper surface opening of the component storage chamber 11 of the housing 10 with almost no gap. The inner member 60 is provided with a circular portion 61 that is one step higher than the surroundings at a position directly above the light emitting diode 2 in a state of being housed in the component storage chamber 11. The inner member 60 is formed with a pair of shoulder surfaces 62 for preventing the bus bar from coming off. In the state where the inner member 60 is housed in the component storage chamber 11, the pair of bus bar pull-out prevention shoulder surfaces 62 are located on the bus bar pull-out side of the gripping piece portion 39 of the bus bar 30.

インナー部材60の両側縁には、一対の側端自重受けリブ63が突設されている。インナー部材60の先端部には、先端自重受けリブ65が設けられている。インナー部材60が部品収容室11に収容された状態では、一対の側端自重受けリブ63が一対のインナー部材保持溝24に入り込んでその底面に載置され、且つ、先端自重受けリブ65がハウジング10のインナー部材支持台22に載置される。インナー部材60には、基板位置決め突起64が設けられている。インナー部材60が部品収容室11に収容された状態では、基板位置決め突起64が回路基板3の挿入後端面の位置決め溝3bに入り込む。 A pair of side end self-weight receiving ribs 63 are projected from both side edges of the inner member 60. A tip weight receiving rib 65 is provided at the tip of the inner member 60.

(照明ユニットの組み付け手順)
次に、照明ユニット1の組み付け手順を説明する。
(Procedure for assembling the lighting unit)
Next, the procedure for assembling the lighting unit 1 will be described.

図12に示すように、バスバー30の把持片部39をチャック治具110で把持し、バスバー30をそのタブ端子32を先端としてハウジング10の部品収容室11のバスバーガイドレール16に載せる。 As shown in FIG. 12, the gripping piece portion 39 of the bus bar 30 is gripped by the chuck jig 110, and the bus bar 30 is placed on the bus bar guide rail 16 of the component accommodating chamber 11 of the housing 10 with its tab terminal 32 as the tip.

図13に示すように、バスバーガイドレール16に載せた各バスバー30の押圧片部36を矢印方向に押す。すると、各バスバー30がバスバーガイドレール16にガイドされて部品収容室11の奥に向かって移動し、タブ端子32が仕切壁13の端子貫通孔25に進入し、コネクタ嵌合室12に入り込む。 As shown in FIG. 13, the pressing piece portion 36 of each bus bar 30 mounted on the bus bar guide rail 16 is pushed in the direction of the arrow. Then, each bus bar 30 is guided by the bus bar guide rail 16 and moves toward the back of the component accommodating chamber 11, and the tab terminal 32 enters the terminal through hole 25 of the partition wall 13 and enters the connector fitting chamber 12.

次に、回路基板3をハウジング10の部品収容室11に挿入する。回路基板3の挿入完了位置では、図14及び図15に示すように、回路基板3の一対の接点部3aがバスバー30の固定接点部34とばね接点部35の間に挟持され、基板接点部31と回路基板3間が電気的に接続される。 Next, the circuit board 3 is inserted into the component storage chamber 11 of the housing 10. At the insertion complete position of the circuit board 3, as shown in FIGS. 14 and 15, a pair of contact portions 3a of the circuit board 3 are sandwiched between the fixed contact portion 34 and the spring contact portion 35 of the bus bar 30, and the substrate contact portion is formed. The 31 and the circuit board 3 are electrically connected.

次に、図16に示すように、ハウジング10の部品収容室11の上方より、一対の側端自重受けリブ63を一対のインナー部材保持溝24に位置合わせして、インナー部材60を部品収容室11に挿入する(図17参照)。 Next, as shown in FIG. 16, the pair of side end self-weight receiving ribs 63 are aligned with the pair of inner member holding grooves 24 from above the component accommodating chamber 11 of the housing 10, and the inner member 60 is placed in the component accommodating chamber. Insert into 11 (see FIG. 17).

次に、ハウジング10の部品収容室11の上方よりカバー50を組み付ける。すると、カバー50の変形規制用リブ54がハウジング10の変形規制用溝21に入り込み、且つ、カバー50の各ロック爪52が弾性変形でハウジング10の各ロック用突起20に係止される。これで、カバー50を装着した照明ユニット1の組み付けが完了する。 Next, the cover 50 is assembled from above the component storage chamber 11 of the housing 10. Then, the deformation control rib 54 of the cover 50 enters the deformation control groove 21 of the housing 10, and each lock claw 52 of the cover 50 is elastically deformed and locked to each lock protrusion 20 of the housing 10. This completes the assembly of the lighting unit 1 with the cover 50 attached.

(照明ユニットの取付穴への取付手順)
次に、カバー50を装着した照明ユニット1を照明取付部材100の取付穴101に取付ける手順を説明する。図18に示すように、照明取付部材(例えば車体パネルのトリム)100の取付穴101は、小径部101aと大径部101bが組み合わされ、小径部101aの外縁側が挟持部101cとされた変則円形の穴である。
(Mounting procedure for mounting holes of lighting unit)
Next, a procedure for attaching the lighting unit 1 to which the cover 50 is attached to the mounting hole 101 of the lighting mounting member 100 will be described. As shown in FIG. 18, the mounting hole 101 of the lighting mounting member (for example, the trim of the vehicle body panel) 100 is an anomaly in which the small diameter portion 101a and the large diameter portion 101b are combined and the outer edge side of the small diameter portion 101a is the holding portion 101c. It is a circular hole.

先ず、カバー側取付部55を大径部101bの位置に合わせ、取付穴101に円筒部53と共にカバー側取付部55を挿入し、図19(a)、(b)に示すように、カバー側取付部55が照明取付部材100の反対面側に突き出る位置まで挿入する。次に、カバー側取付部55を回転する。すると、弾性円弧アーム部55bが弾性変形し、係止爪55cが挟持部101cに載り、カバー50の回転が許容される。係止爪55cが挟持部101cを乗り越える位置まで回転する。すると、図20(a)、(b)に示すように、弾性円弧アーム部55bが弾性復帰変形し、突部55dと弾性円弧アーム部55bが挟持101cの両面間を挟み込み、且つ、カバー側取付部55の回転ストッパ壁55aと係止爪55cが挟持部101cの両端面間を挟み込む。これで、照明ユニット1が照明取付部材100の取付穴101に取り付けされ、照明ユニット1の設置が完了する。 First, the cover-side mounting portion 55 is aligned with the position of the large-diameter portion 101b, the cover-side mounting portion 55 is inserted into the mounting hole 101 together with the cylindrical portion 53, and as shown in FIGS. 19A and 19B, the cover-side mounting portion 55 is inserted. The mounting portion 55 is inserted until it protrudes to the opposite surface side of the lighting mounting member 100. Next, the cover side mounting portion 55 is rotated. Then, the elastic arc arm portion 55b is elastically deformed, the locking claw 55c is placed on the holding portion 101c, and the cover 50 is allowed to rotate. The locking claw 55c rotates to a position where it gets over the holding portion 101c. Then, as shown in FIGS. 20A and 20B, the elastic arc arm portion 55b is elastically restored and deformed, and the protrusion 55d and the elastic arc arm portion 55b sandwich the sandwiching 101c between both sides and are attached to the cover side. The rotation stopper wall 55a of the portion 55 and the locking claw 55c sandwich between both end faces of the sandwiching portion 101c. This completes the installation of the lighting unit 1 by mounting the lighting unit 1 in the mounting holes 101 of the lighting mounting member 100.

カバー側取付部55を照明取付部材100の取付穴1010への取付け時には、作業者がハウジング10を把持し、図21(a)の矢印方向にハウジング10を回転する。すると、ハウジング10がカバー50に回転力を作用し、その際にハウジング10がカバー50より回転反力を受ける。この回転反力を一対の側壁15の変形規制用溝21の垂直面21aで受けるため、回転反力が一対の側壁15を開く方向に作用しない。従って、ハウジング10は、一対の側壁15を開く方向には変形しない。 When mounting the cover-side mounting portion 55 to the mounting hole 1010 of the lighting mounting member 100, the operator grips the housing 10 and rotates the housing 10 in the direction of the arrow in FIG. 21 (a). Then, the housing 10 exerts a rotational force on the cover 50, and at that time, the housing 10 receives a rotational reaction force from the cover 50. Since this rotational reaction force is received by the vertical surfaces 21a of the deformation regulating grooves 21 of the pair of side walls 15, the rotational reaction force does not act in the direction of opening the pair of side walls 15. Therefore, the housing 10 does not deform in the direction of opening the pair of side walls 15.

より詳細には、図21(b)に示すように、カバー側取付部55を照明取付部材100の取付穴1010への取付け時には、作業者がハウジング10を把持し、ハウジング10を円筒部53の中心Oを回転中心として回転する。すると、ハウジング10の変形規制用溝21の垂直面21aでカバー50の変形規制用リブ54の垂直面54aを押圧力Fで押圧し、カバー50に回転力が伝達されてカバー50が回転する。その際に、ハウジング10は、カバー50の変形規制用リブ54の垂直面54aが変形規制用溝21の垂直面21aを押圧する反力Rを受けるが、この反力Rは、各側壁15の延設方向であり、ハウジング10の一対の側壁15を開く方向(互いに離間する方向)には作用しない。尚、実施形態とは逆方向の回転でハウジング10に取り付ける構造となっている場合には、上記動作とは反対側の垂直面21a,垂直面54aに押圧力F及び反力Rが作用し、同様に、ハウジング10の一対の側壁15を開く方向(互いに離間する方向)には作用しない。 More specifically, as shown in FIG. 21B, when the cover side mounting portion 55 is mounted on the mounting hole 1010 of the lighting mounting member 100, the operator grips the housing 10 and the housing 10 is attached to the cylindrical portion 53. It rotates with the center O as the center of rotation. Then, the vertical surface 21a of the deformation restricting groove 21 of the housing 10 presses the vertical surface 54a of the deformation regulating rib 54 of the cover 50 with the pressing force F, and the rotational force is transmitted to the cover 50 to rotate the cover 50. At that time, the housing 10 receives a reaction force R in which the vertical surface 54a of the deformation regulating rib 54 of the cover 50 presses the vertical surface 21a of the deformation regulating groove 21, and this reaction force R is applied to each side wall 15. It is an extension direction and does not act in the direction in which the pair of side walls 15 of the housing 10 are opened (directions separated from each other). When the structure is such that the housing 10 is attached to the housing 10 by rotating in the direction opposite to that of the embodiment, the pressing force F and the reaction force R act on the vertical surface 21a and the vertical surface 54a on the opposite side to the above operation. Similarly, it does not act in the direction in which the pair of side walls 15 of the housing 10 are opened (directions separated from each other).

図21(c)に示すように、変形規制用溝21と変形規制用リブ54を設けていない場合、ハウジング10を回転し、照明取付部材100の取付穴101に回転取付けする時には、ハウジング10がカバー50に回転力を作用し、その際にハウジング10がカバー50より回転反力を受けるが、回転反力を一対の側壁15の内側面15aで受けるため、回転反力が一対の側壁15を開く方向に作用し、ハウジング10が一対の側壁15を開く方向に変形する。 As shown in FIG. 21 (c), when the deformation control groove 21 and the deformation control rib 54 are not provided, when the housing 10 is rotated and rotationally mounted in the mounting hole 101 of the lighting mounting member 100, the housing 10 is mounted. A rotational force is applied to the cover 50, and the housing 10 receives a rotational reaction force from the cover 50 at that time. However, since the rotational reaction force is received by the inner side surfaces 15a of the pair of side walls 15, the rotational reaction force receives the pair of side walls 15. Acting in the opening direction, the housing 10 deforms in the opening direction of the pair of side walls 15.

より詳細には、カバー側取付部55を照明取付部材100の取付穴1010への取付け時には、作業者がハウジング10を把持し、ハウジング10を円筒部53の中心Oを回転中心として回転する。すると、ハウジング10の一対の側壁15の内側面15aがカバー50の外側面50aを押圧力fで押圧し、その反力rをハウジング10が受ける。この反力rは、一対の側壁15に直交する方向で回転中心Oを通る補助線Sを境として、一方側の部位と他方側の部位で互いに逆向きの力となり、ハウジング10の一対の側壁15を開く方向(互いに離間する方向)に作用し、ハウジング10が一対の側壁15を開く方向に変形する。 More specifically, when the cover side mounting portion 55 is mounted on the mounting hole 1010 of the lighting mounting member 100, the operator grips the housing 10 and rotates the housing 10 with the center O of the cylindrical portion 53 as the center of rotation. Then, the inner side surfaces 15a of the pair of side walls 15 of the housing 10 press the outer surface 50a of the cover 50 with the pressing force f, and the housing 10 receives the reaction force r. This reaction force r becomes a force in opposite directions at one side portion and the other side portion with the auxiliary line S passing through the rotation center O in the direction orthogonal to the pair of side walls 15 as a boundary, and the pair of side walls of the housing 10. It acts in the direction in which the 15s are opened (directions separated from each other), and the housing 10 is deformed in the direction in which the pair of side walls 15 are opened.

(実施形態の効果)
以上、照明ユニット1は、底壁14と底壁14より立設する一対の立設壁である側壁15に囲まれた部品収容室11を有し、部品収容室11に光源である発光ダイオード2と発光ダイオード2から外部間の回路を構成する回路体である回路基板3及びバスバー30とを収容するハウジング10と、ハウジング10にロック手段(ロック用突起20とロック爪52)によって装着されて部品収容室11の開口を塞ぎ、照明取付部材100の取付穴101に回転で取付けできるカバー側取付部55を有するカバー50とを備え、ハウジング10の一対の側壁15には変形規制用溝21が設けられ、カバー50には変形規制用溝21に入り込む変形規制用リブ54が設けられている。
(Effect of embodiment)
As described above, the lighting unit 1 has a component accommodating chamber 11 surrounded by a bottom wall 14 and a side wall 15 which is a pair of erecting walls erected from the bottom wall 14, and the light emitting diode 2 which is a light source is provided in the component accommodating chamber 11. A housing 10 that houses a circuit board 3 and a bus bar 30, which are circuits that form a circuit between the light emitting diode 2 and the outside, and a component that is mounted on the housing 10 by locking means (locking protrusion 20 and lock claw 52). A cover 50 having a cover-side mounting portion 55 that closes the opening of the accommodation chamber 11 and can be mounted in the mounting hole 101 of the lighting mounting member 100 by rotation is provided, and a deformation control groove 21 is provided on the pair of side walls 15 of the housing 10. The cover 50 is provided with a deformation regulating rib 54 that enters the deformation regulating groove 21.

従って、ハウジング10を回転し、照明取付部材100の取付穴101に回転取付けする時には、上記したように、ハウジング10がカバー50より反力を受けるが、反力を一対の側壁15の変形規制用溝21の垂直面21aで受けるため、反力が一対の側壁15を開く方向に作用せず、ロック手段(ロック用突起20とロック爪52)が外れて、カバー50がハウジング10から外れるのを極力防止できる。 Therefore, when the housing 10 is rotated and mounted in the mounting hole 101 of the lighting mounting member 100, the housing 10 receives a reaction force from the cover 50 as described above, but the reaction force is used to regulate the deformation of the pair of side walls 15. Since it is received by the vertical surface 21a of the groove 21, the reaction force does not act in the direction of opening the pair of side walls 15, and the locking means (locking protrusion 20 and lock claw 52) are disengaged so that the cover 50 is disengaged from the housing 10. It can be prevented as much as possible.

ロック手段は、ハウジング10の一対の側壁15の内面側に設けられ、内側に向かって突出するロック用突起20と、カバー50の外側面に設けられ、外側に向かって突出するロック爪52とを有する。 The locking means is provided on the inner surface side of the pair of side walls 15 of the housing 10 and has a locking protrusion 20 that projects inward, and a lock claw 52 that is provided on the outer surface of the cover 50 and projects outward. Have.

ロック手段は、ハウジング10の一対の側壁15間の幅寸法W(図2(a)、図3(a)に示す)の範囲内に配置されている。従って、照明ユニット1のコンパクト化になるロック手段であるが、ハウジング10の一対の側壁15が開く方向に変形すると、ロック用突起20とロック爪52の係止が外れる方向である。しかし、照明取付部材100の取付穴101への回転取付け時には、上記したように、一対の側壁15を開く方向回転の反力が作用しないため、カバー50がハウジング10より外れることを防止できる。従って、照明ユニット1のコンパクト化を図りつつ、照明ユニット1の回転取付け時のカバー50のはずれ防止を図ることができる。 The locking means is arranged within the width dimension W (shown in FIGS. 2A and 3A) between the pair of side walls 15 of the housing 10. Therefore, although it is a locking means for making the lighting unit 1 compact, when the pair of side walls 15 of the housing 10 are deformed in the opening direction, the locking projection 20 and the lock claw 52 are unlocked. However, when the lighting mounting member 100 is rotationally mounted in the mounting hole 101, as described above, the reaction force of the rotation in the direction of opening the pair of side walls 15 does not act, so that the cover 50 can be prevented from coming off from the housing 10. Therefore, it is possible to prevent the cover 50 from coming off when the lighting unit 1 is rotationally mounted while making the lighting unit 1 compact.

カバー50は、一対の側壁15の内面に入り込む位置でハウジング10に装着されている。つまり、カバー50は、ハウジング10の一対の側壁15間の幅寸法W(図2(a)、図3(a)に示す)の範囲内に配置される。従って、照明ユニット1のコンパクト化になるが、このようなカバー50にあって、変形規制用溝21と変形規制用リブ54を設けていない場合、上記したようにカバー50がハウジング10から外れ易い構造となる(図21(c)の説明参照)。しかし、照明取付部材100の取付穴101への回転取付け時には、上記したように、一対の側壁15を開く方向の反力が作用しないため、カバー50がハウジング10より外れることを防止できる。従って、照明ユニット1のコンパクト化を図りつつ、照明ユニット1の回転取付け時のカバー50のはずれ防止を図ることができる。 The cover 50 is attached to the housing 10 at a position where it enters the inner surface of the pair of side walls 15. That is, the cover 50 is arranged within the range of the width dimension W (shown in FIGS. 2A and 3A) between the pair of side walls 15 of the housing 10. Therefore, although the lighting unit 1 is made compact, if the cover 50 is not provided with the deformation regulating groove 21 and the deformation regulating rib 54, the cover 50 is likely to come off from the housing 10 as described above. It becomes a structure (see the explanation of FIG. 21C). However, when the lighting mounting member 100 is rotationally mounted in the mounting hole 101, as described above, the reaction force in the direction of opening the pair of side walls 15 does not act, so that the cover 50 can be prevented from coming off from the housing 10. Therefore, it is possible to prevent the cover 50 from coming off when the lighting unit 1 is rotationally mounted while making the lighting unit 1 compact.

部品収容室11の開口は、一対の側壁15の上面と側面の二面が連通した領域である。従って、部品収容室11に光源である発光ダイオード2、回路体である回路基板3及びバスバー30を挿入し易いが、ハウジング10は、一対の側壁15が開く方向に変形し易い構造となる。しかし、照明取付部材100の取付穴101への回転取付け時には、上記したように、一対の側壁15を開く方向の反力が作用しないため、カバー50がハウジング10より外れることを防止できる。従って、ハウジング10の部品収容室11への収容作業性の向上を図りつつ、照明ユニット1の回転取付け時のカバー50のはずれ防止を図ることができる。 The opening of the component accommodating chamber 11 is a region in which the upper surface and the two side surfaces of the pair of side walls 15 communicate with each other. Therefore, although it is easy to insert the light emitting diode 2 which is a light source, the circuit board 3 which is a circuit body, and the bus bar 30 into the component accommodating chamber 11, the housing 10 has a structure which is easily deformed in the direction in which the pair of side walls 15 are opened. However, when the lighting mounting member 100 is rotationally mounted in the mounting hole 101, as described above, the reaction force in the direction of opening the pair of side walls 15 does not act, so that the cover 50 can be prevented from coming off from the housing 10. Therefore, it is possible to prevent the cover 50 from coming off when the lighting unit 1 is rotationally attached, while improving the workability of accommodating the housing 10 in the component accommodating chamber 11.

インナー部材60には、一対のバスバー抜け防止肩面62と一対の側端自重受けリブ63と基板位置決め突起64が設けられている。インナー部材60を部品収容室11に収容する際に、一対のバスバー抜け防止肩面62は、バスバー30が半挿入状態であればバスバー30の把持片部39に干渉し、一対の側端自重受けリブ63は、ハウジング10の部品収容室11の適正位置に収容されていなければ、ハウジング10のインナー部品保持溝24より浮き上がり、基板位置決め突起64は、回路基板3が半挿入状態であれば、回路基板3の位置決め溝3bに入り込まず、仮に入り込んだ状態でもインナー部材60が部品収容室11に収容されずに浮き上がった状態となる。従って、インナー部材60は、バスバー30と回路基板3とハウジング10間が適正な状態で組み付けられているか否かを検知する機能(半嵌合検知機能)を有する。 The inner member 60 is provided with a pair of bus bar pull-out prevention shoulder surfaces 62, a pair of side end self-weight receiving ribs 63, and a substrate positioning protrusion 64. When the inner member 60 is accommodated in the component accommodating chamber 11, the pair of bus bar removal prevention shoulder surfaces 62 interferes with the gripping piece portion 39 of the bus bar 30 if the bus bar 30 is in the half-inserted state, and the pair of side end self-weight receivers. If the rib 63 is not accommodated in the proper position of the component accommodating chamber 11 of the housing 10, the rib 63 is lifted from the inner component holding groove 24 of the housing 10, and the substrate positioning projection 64 is a circuit if the circuit board 3 is in the semi-inserted state. The inner member 60 is not accommodated in the component accommodating chamber 11 and is in a raised state even if it is temporarily entered without entering the positioning groove 3b of the substrate 3. Therefore, the inner member 60 has a function (semi-fitting detection function) of detecting whether or not the bus bar 30, the circuit board 3, and the housing 10 are properly assembled.

インナー部材60は、ハウジング10に弾性ロック構造でロックする部品ではなく、ハウジング10の部品収容室11内に単に落とし込むことで収容する部品であるため、バスバー30と回路基板3とハウジング10間が適正な状態で組み付けられているか否かを、内部に収容された部品である回路基板3やバスバー30に荷重を作用させることなく検知できる。つまり、回路基板3やバスバー30に何らのダメージを与えることなく検知できる。 Since the inner member 60 is not a component that is locked to the housing 10 by an elastic lock structure, but is a component that is accommodated by simply dropping it into the component accommodating chamber 11 of the housing 10, the space between the bus bar 30, the circuit board 3, and the housing 10 is appropriate. Whether or not it is assembled in such a state can be detected without applying a load to the circuit board 3 and the bus bar 30, which are components housed inside. That is, it can be detected without causing any damage to the circuit board 3 and the bus bar 30.

バスバー30と回路基板3が適正な状態に配置された部品収容室11にインナー部材60が収容された場合には、一対の側端自重受けリブ63が一対のインナー部材保持溝24に入り込んで載置され、且つ、先端自重受けリブ65がハウジング10のインナー部材支持台22に載置され、インナー部材62の自重をハウジング10で受ける。従って、インナー部材60をハウジング10に組み込んだ後でも、インナー部材60の自重が回路基板3や一対のバスバー30に作用しないため、インナー部材60が回路基板3やバスバー30にダメージを与えることがない。 When the inner member 60 is accommodated in the component accommodating chamber 11 in which the bus bar 30 and the circuit board 3 are arranged in an appropriate state, the pair of side end self-weight receiving ribs 63 are inserted into the pair of inner member holding grooves 24 and mounted. The tip weight receiving rib 65 is placed on the inner member support base 22 of the housing 10, and the weight of the inner member 62 is received by the housing 10. Therefore, even after the inner member 60 is incorporated into the housing 10, the weight of the inner member 60 does not act on the circuit board 3 or the pair of bus bars 30, so that the inner member 60 does not damage the circuit board 3 or the bus bar 30. ..

カバー50は、光を透過しない部材で形成され、取付穴101に配置される円筒部53を有し、円筒部53の開口を閉塞する光透過性のインナー部材60がハウジング10に収容されている。従って、カバー50の円筒部53内の開口よりハウジング10内に塵埃、水等の異物が入るのを防止できる。 The cover 50 is formed of a member that does not transmit light, has a cylindrical portion 53 arranged in the mounting hole 101, and has a light-transmitting inner member 60 that closes the opening of the cylindrical portion 53 in the housing 10. .. Therefore, it is possible to prevent foreign matter such as dust and water from entering the housing 10 through the opening in the cylindrical portion 53 of the cover 50.

インナー部材60には、一対のバスバー抜け防止肩面62が設けられている。カバー50がハウジング10に装着された状態では、バスバー30の把持片部39がバスバー抜け方向に移動するのを阻止できる。 The inner member 60 is provided with a pair of shoulder surfaces 62 for preventing the bus bar from coming off. When the cover 50 is attached to the housing 10, the gripping piece portion 39 of the bus bar 30 can be prevented from moving in the direction in which the bus bar is removed.

照明ユニット1では、回路基板3の挿入先端面の位置決め溝3bにハウジング10の基板位置決め突起26が入り込み、回路基板3の挿入後端面の位置決め溝3bにインナー部材60の基板位置決め突起64が入り込む。従って、回路基板3がハウジング10の部品収容室11内に位置決めされた状態で収容される。 In the lighting unit 1, the substrate positioning projection 26 of the housing 10 is inserted into the positioning groove 3b on the insertion tip surface of the circuit board 3, and the substrate positioning projection 64 of the inner member 60 is inserted into the positioning groove 3b on the insertion rear end surface of the circuit board 3. Therefore, the circuit board 3 is accommodated in the component accommodating chamber 11 of the housing 10 in a positioned state.

(カバー側取付部の変形例)
図22には、変形例のカバー側取付部55を適用したカバー50Aが示されている。カバー側取付部55は、前記実施形態のものと同様に、円筒部53の180度対向位置に設けられ、円筒部53の外周より突出する一対の回転ストッパ壁55aを有する。前記実施形態のものは、各回転ストッパ壁55aの一方側にのみ弾性円弧アーム55b、係止爪55c及び突部55dが設けられていたが、この変形例では、各回転ストッパ壁55aの両側に弾性円弧アーム55b、係止爪55c及び突部55dが設けられている。
(Modification example of the cover side mounting part)
FIG. 22 shows a cover 50A to which the cover-side mounting portion 55 of the modified example is applied. The cover-side mounting portion 55 is provided at a position 180 degrees opposite to the cylindrical portion 53, and has a pair of rotation stopper walls 55a protruding from the outer circumference of the cylindrical portion 53, as in the above embodiment. In the above embodiment, the elastic arc arm 55b, the locking claw 55c and the protrusion 55d are provided only on one side of each rotation stopper wall 55a, but in this modified example, both sides of each rotation stopper wall 55a are provided. An elastic arc arm 55b, a locking claw 55c, and a protrusion 55d are provided.

前記実施形態と同一構成箇所には、図面に前記実施形態のものと同じ符号を付して重複説明を省略する。 The same components as those in the embodiment are designated by the same reference numerals as those in the embodiment in the drawings, and duplicate description will be omitted.

このカバー50Aでは、左右どの方向の回転でも照明取付部材100の取付穴101に取付けできる。従って、左右対称位置に照明取付部材100が配置され、左右の取付穴101に左右同じ向きで照明ユニット1を取付ける場合に、互いに逆回転方向で照明ユニット1を取付けでき、取付け作業性が良い。例えば、車体の左右ドアに対し、左右同じ取付位置で照明ユニット1を取付けする場合に、右ドアでは右回転(左回転)で、左ドアでは左回転(右回転)で取付けできる。 With this cover 50A, it can be mounted in the mounting hole 101 of the lighting mounting member 100 by rotating in any of the left and right directions. Therefore, when the lighting mounting members 100 are arranged symmetrically and the lighting units 1 are mounted in the left and right mounting holes 101 in the same directions on the left and right, the lighting units 1 can be mounted in opposite directions to each other, and the mounting workability is good. For example, when the lighting unit 1 is mounted on the left and right doors of the vehicle body at the same mounting position on the left and right, the lighting unit 1 can be mounted by rotating clockwise (clockwise) at the right door and rotating counterclockwise (clockwise) at the left door.

(その他の変形例)
前記実施形態では、ハウジング10にコネクタ嵌合室12が設けられ、バスバー30にタブ端子32が設けられ、バスバー30と外部から導かれた電線との間の電気的接続をコネクタ接続によって行うよう構成されているが、コネクタ接続以外で接続しても良い。例えば、バスバー30に圧接刃端子を設け、バスバー30と外部から導かれた電線との電線的接続を圧接接続によって行っても良い。
(Other variants)
In the above embodiment, the housing 10 is provided with the connector fitting chamber 12, the bus bar 30 is provided with the tab terminal 32, and the electrical connection between the bus bar 30 and the electric wire guided from the outside is made by the connector connection. However, it may be connected by other than the connector connection. For example, the bus bar 30 may be provided with a pressure welding blade terminal, and the bus bar 30 may be connected to an electric wire guided from the outside by pressure welding.

前記実施形態では、回路体は、回路基板3とバスバー30より構成されているが、これに限定されるものではない。例えば、電子部品が搭載されたバスバー回路体より構成しても良い。この場合には、バスバー回路体に一体にタブ端子や圧接刃端子を設けることが好ましい。 In the above embodiment, the circuit body is composed of the circuit board 3 and the bus bar 30, but is not limited thereto. For example, it may be composed of a bus bar circuit body on which electronic components are mounted. In this case, it is preferable to provide a tab terminal and a pressure welding blade terminal integrally with the bus bar circuit body.

前記実施形態では、カバー50を装着する場合には、ハウジング10内にインナー部材60を収容するよう構成されているが、カバー50の円筒部53内に光透過性部材を例えば二色成形によって設けた構成としても良い。 In the above embodiment, when the cover 50 is mounted, the inner member 60 is accommodated in the housing 10, but a light transmitting member is provided in the cylindrical portion 53 of the cover 50 by, for example, two-color molding. It may be configured as a new type.

ハウジング10には、キャップ用ロック突起29が設けられている。従って、カバー50の円筒部53を外側から覆い、円筒部53からの光を外部に出射するキャップ(図示せず)が装着可能である。照明ユニット1は、キャップを装着することにより、発光形態のバリエーションを増やすことができる。又、キャップの種類を増やすことによっても発光形態のバリエーションを増やすことができる。 The housing 10 is provided with a cap lock protrusion 29. Therefore, a cap (not shown) that covers the cylindrical portion 53 of the cover 50 from the outside and emits light from the cylindrical portion 53 to the outside can be attached. By attaching a cap to the lighting unit 1, variations in light emitting form can be increased. Further, the variation of the light emitting form can be increased by increasing the types of caps.
