(1) a bulb having a light bulb part and a plate-like base part connected to the light bulb part;
A housing having an electric wire connecting portion for electrically connecting electric wires;
A terminal portion disposed in the wire connection portion, and a pair of spring terminal portions that are elastically deformed in a direction approaching and separating from each other to sandwich the base portion of the valve and electrically connect to the valve. A bus bar mounted on the housing;
After the bus bar is mounted on the housing and an electric wire is electrically connected to the terminal portion, and before the valve is electrically connected to the spring terminal portion, the terminal portion is covered. A cover attached to the housing;
An interior lighting comprising:
The cover further includes an electrode protection portion that positions the spring terminal portion in a valve insertion space defined between the cover and the housing when the cover is attached to the housing;
The electrode protection portion is inserted when the bulb is inserted into the bulb insertion space from the base portion side and electrically connected to the spring terminal portion, and the bulb is inserted with an inclination more than a normal insertion angle. Accordingly, when the spring terminal portion is about to be excessively displaced toward the cover side, the spring terminal portion has an excessive displacement prevention portion that contacts the spring terminal portion and prevents excessive displacement of the spring terminal.

thing.
(5) The room illumination lamp having any one of the above-mentioned (1) to (4),

thing.
　上記（１）の構成の室内照明灯では、バルブがバルブ挿入空間に挿し込まれる際に、バルブが正規な挿入角度よりも傾いて挿入され、当該傾いたバルブによってバネ端子部がカバー側に押圧されて過大変位しようとした場合に、バネ端子部が電極保護部の過大変位防止部に当接することによって当該過大変位が防止される。したがって、正規な挿入角度よりも傾いた状態でバルブが挿し込まれること（換言すれば、斜め挿入。）で生じるバネ端子部の過大変形を抑制することができる。これにより、バルブのベース部とバスバーのバネ端子部との良好な導通接触状態を維持することができ、バルブとバスバーとの接続の信頼性を向上させることができる。
　上記（２）の構成の室内照明灯では、バルブがバルブ挿入空間に挿し込まれる際に、バルブが電極保護部のガイド部に摺接されることにより案内され、これによりバルブの斜め挿入が防止される。このため、正規な挿入角度よりも傾いた状態でバルブが挿し込まれる事象の発生を抑制でき、バネ端子部の過大変形を抑制することができる。
　上記（３）の構成の室内照明灯では、カバーをハウジングに装着すると、電極保護部のロック部がハウジングの係止部を係止して、カバーのハウジングへの装着状態が維持される。これにより、カバーの保持力が向上する。このため、例えば電線が引っ張られたとしても、カバーが外れるような不具合の発生を抑制することができ、バスバーの端子部と電線との接続の信頼性を向上させることができる。
　上記（４）の構成の室内照明灯では、バスバーの位置決め部がハウジング及び電極保護部の嵌合部に嵌合されることで、バスバーの移動が規制される。これにより、バスバーをハウジングの所定位置に良好に位置決めすることができ、組み付け精度が向上する。この結果、バルブとバスバーとの接続の信頼性を向上させることができる。
　上記（５）の構成の室内照明灯では、電極保護部によってバスバーにおけるバネ端子部のカバー側の全面が覆われて露出が防止されているので、バスバーのバネ端子部の絶縁性能を向上させることができる。 In the indoor illumination lamp having the above configuration (1), when the bulb is inserted into the bulb insertion space, the bulb is inserted with an inclination relative to the normal insertion angle, and the spring terminal portion is pressed toward the cover by the inclined bulb. When an excessive displacement is attempted, the spring terminal portion comes into contact with the excessive displacement prevention portion of the electrode protection portion, thereby preventing the excessive displacement. Therefore, it is possible to suppress excessive deformation of the spring terminal portion that occurs when the valve is inserted in a state inclined from the normal insertion angle (in other words, oblique insertion). Thereby, the favorable conduction contact state of the base part of a valve | bulb and the spring terminal part of a bus bar can be maintained, and the reliability of the connection of a valve | bulb and a bus bar can be improved.
In the indoor lamp having the configuration (2), when the bulb is inserted into the bulb insertion space, the bulb is guided by sliding contact with the guide portion of the electrode protection portion, thereby preventing the bulb from being inserted obliquely. Is done. For this reason, generation | occurrence | production of the event by which a valve | bulb is inserted in the state inclined rather than the regular insertion angle can be suppressed, and the excessive deformation | transformation of a spring terminal part can be suppressed.
In the indoor illumination lamp having the configuration (3), when the cover is mounted on the housing, the lock portion of the electrode protection portion locks the locking portion of the housing, and the mounting state of the cover on the housing is maintained. Thereby, the holding | maintenance force of a cover improves. For this reason, even if the electric wire is pulled, for example, it is possible to suppress the occurrence of a problem that the cover is removed, and to improve the reliability of the connection between the terminal portion of the bus bar and the electric wire.
In the indoor illumination lamp having the configuration (4), the movement of the bus bar is restricted by fitting the positioning portion of the bus bar to the fitting portion of the housing and the electrode protection portion. Thereby, the bus bar can be satisfactorily positioned at a predetermined position of the housing, and the assembling accuracy is improved. As a result, the reliability of connection between the valve and the bus bar can be improved.
In the interior illumination lamp having the configuration of (5) above, the electrode protection portion covers the entire surface of the bus bar on the cover side of the spring terminal portion to prevent exposure, thereby improving the insulation performance of the spring terminal portion of the bus bar. Can do.
　本発明によれば、バネ端子部における過大変位の発生を抑制可能な室内照明灯を提供できる。 According to the present invention, it is possible to provide an indoor lamp capable of suppressing the occurrence of excessive displacement at the spring terminal portion.

　図１から図３に示すように、本実施形態に係る室内照明灯１は、絶縁樹脂製のハウジング１０と、点灯及び消灯を行うためのスイッチ２０と、回路を構成する導電金属製のバスバー３０と、絶縁樹脂製の圧接カバー４０（カバー）と、光源であるバルブ５０と、スイッチ２０を保護するための絶縁樹脂製のスイッチカバー６０と、を備えている。 As shown in FIG. 1 to FIG. 3, an interior lighting 1 according to the present embodiment includes an insulating resin housing 10, a switch 20 for turning on and off, and a conductive metal bus bar 30 constituting a circuit. And a pressure contact cover 40 (cover) made of an insulating resin, a bulb 50 that is a light source, and a switch cover 60 made of an insulating resin for protecting the switch 20.
　尚、以下、本明細書中では、図１中に矢印Ｆ、Ｂ、Ｕ、Ｄ、Ｌ、Ｒで示すように前側、後側、上側、下側、左側、右側を規定して説明するが、これらは使用時における方向を限定するものではない。例えば、本実施形態に係る室内照明灯１は、車両天井部の内装材（図示せず。）に後述するハウジング１０の底板１５が対向するように取り付けられた場合、図１中の矢印における上向きが鉛直下向きとなる。即ち、本実施形態に係る室内照明灯１は、図２に示す姿勢で車両天井部の内装材に取り付けられて用いられる。 In the following description, the front side, the rear side, the upper side, the lower side, the left side, and the right side are defined as shown by arrows F, B, U, D, L, and R in FIG. These do not limit the direction in use. For example, when the interior lighting 1 according to the present embodiment is attached so that a bottom plate 15 of the housing 10 described later faces an interior material (not shown) of the vehicle ceiling, the upward direction indicated by the arrow in FIG. Is vertically downward. That is, the interior lighting 1 according to the present embodiment is used by being attached to the interior material of the vehicle ceiling in the posture shown in FIG.
　図４に示すように、ハウジング１０は、略平坦な底板１５を有し、その上側に部品を装備できるように形成されている。このハウジング１０は、前端側に、前方からバルブ５０を装着するためのバルブ装着部１１を有し、後端側に、スイッチ２０を装着するためのスイッチ装着部１３を有し、バルブ装着部１１とスイッチ装着部１３との間に、バスバー３０が配置されると共に電線７０が配索される溝状の電線接続部１２を有している。 As shown in FIG. 4, the housing 10 has a substantially flat bottom plate 15 and is formed so that components can be mounted on the upper side thereof. The housing 10 has a valve mounting portion 11 for mounting the valve 50 from the front on the front end side, and a switch mounting portion 13 for mounting the switch 20 on the rear end side. Between the switch mounting portion 13 and the switch mounting portion 13, the bus bar 30 is disposed and the groove-shaped wire connecting portion 12 in which the electric wire 70 is routed is provided.
　ハウジング１０には、前後方向におけるバルブ装着部１１と電線接続部１２との間に、嵌合溝（即ち、嵌合部。）１６が形成されている。また、ハウジング１０には、嵌合溝１６の左右両外側に、係止孔１７を有する一対の係止板部（即ち、係止部。）１８がそれぞれ立設されている。 In the housing 10, a fitting groove (that is, a fitting portion) 16 is formed between the valve mounting portion 11 and the wire connecting portion 12 in the front-rear direction. In addition, a pair of locking plate portions (that is, locking portions) 18 having locking holes 17 are erected on the housing 10 on both the left and right outer sides of the fitting groove 16.
　また、ハウジング１０には、電線接続部１２における四隅に、係止突起１９がそれぞれ形成されている。 The housing 10 is formed with locking projections 19 at the four corners of the wire connecting portion 12.
　バスバー３０は、ハウジング１０の電線接続部１２に上方から装着されるもので、前端側に、バルブ装着部１１に装着されるバルブ５０と電気的に接続する電極部３１を有している。また、バスバー３０は、後端側に、スイッチ装着部１３に装着されるスイッチ２０と電気的に接続するスイッチ端子部３３を有している。そして、バスバー３０は、電極部３１とスイッチ端子部３３との前後方向における中間部に、電線７０を圧接により電気的に接続するための圧接端子部３２（即ち、端子部。）を有している。 The bus bar 30 is attached to the electric wire connection part 12 of the housing 10 from above, and has an electrode part 31 electrically connected to the valve 50 attached to the valve attachment part 11 on the front end side. Further, the bus bar 30 has a switch terminal portion 33 that is electrically connected to the switch 20 mounted on the switch mounting portion 13 on the rear end side. And the bus-bar 30 has the press-contact terminal part 32 (namely, terminal part) for electrically connecting the electric wire 70 by press-contact in the intermediate part in the front-back direction of the electrode part 31 and the switch terminal part 33. FIG. Yes.
　バスバー３０の電極部３１には、位置決め板部（即ち、位置決め部。）３４が設けられている。この位置決め板部３４は、前端部が上下に張り出した板状に形成されている。即ち、位置決め板部３４は、上下方向（即ち、バスバー３０のハウジング１０に対する装着方向。）に延びる部分を有しており、下方側の部分３４ａと、上方側の部分３４ｂとを有している。図５に示すように、位置決め板部３４の下方側の部分３４ａは、ハウジング１０の嵌合溝１６に圧入等によって挿し込まれる。これにより、バスバー３０は、ハウジング１０に位置決めされた状態に保持される。しかも、位置決め板部３４が嵌合溝１６の前後両端の壁部に突き当たることで、ハウジング１０の前後方向（即ち、図４における矢印Ａ方向。）への移動が規制され、さらに、位置決め板部３４の表裏面が嵌合溝１６の左右両側の壁面に当接することで、ハウジング１０の左右方向（即ち、図４における矢印Ｂ方向。）への移動が規制される。また、バスバー３０の電極部３１は、２つの接点部３５を有している。これらの接点部３５は、互いに近接する方向へ突出するように湾曲された部分（図９参照。）を有する上下一対のバネ端子部３６から構成されている。 A positioning plate portion (that is, a positioning portion) 34 is provided on the electrode portion 31 of the bus bar 30. The positioning plate portion 34 is formed in a plate shape with the front end portion extending vertically. That is, the positioning plate portion 34 has a portion extending in the vertical direction (that is, the mounting direction of the bus bar 30 with respect to the housing 10), and has a lower portion 34a and an upper portion 34b. . As shown in FIG. 5, the lower portion 34 a of the positioning plate 34 is inserted into the fitting groove 16 of the housing 10 by press fitting or the like. Thereby, the bus bar 30 is held in a state of being positioned in the housing 10. Moreover, when the positioning plate portion 34 abuts against the wall portions at both front and rear ends of the fitting groove 16, the movement of the housing 10 in the front-rear direction (that is, the direction of arrow A in FIG. 4) is restricted. When the front and back surfaces of 34 abut against the left and right wall surfaces of the fitting groove 16, the movement of the housing 10 in the left-right direction (that is, the arrow B direction in FIG. 4) is restricted. The electrode part 31 of the bus bar 30 has two contact parts 35. These contact portions 35 are composed of a pair of upper and lower spring terminal portions 36 having portions (see FIG. 9) curved so as to protrude in directions close to each other.
　バスバー３０のスイッチ端子部３３には、複数の接点３７が形成されており、これらの接点３７がハウジング１０のスイッチ装着部１３に配置される。 A plurality of contacts 37 are formed on the switch terminal portion 33 of the bus bar 30, and these contacts 37 are arranged on the switch mounting portion 13 of the housing 10.
　また、バスバー３０の圧接端子部３２には、複数の圧接刃３８が設けられている。これらの圧接刃３８は、電線７０が押し付けられることにより、電線７０の被覆から内部の導体を露出させ、その導体と電気的に接続する。これにより、電線７０からバスバー３０へ電力が供給可能とされる。 Further, a plurality of press contact blades 38 are provided on the press contact terminal portion 32 of the bus bar 30. When the electric wire 70 is pressed, these press contact blades 38 expose the inner conductor from the coating of the electric wire 70 and are electrically connected to the conductor. Thereby, electric power can be supplied from the electric wire 70 to the bus bar 30.
　図６に示すように、圧接カバー４０は、バスバー３０の圧接端子部３２を保護するためのものであり、電線７０の圧接後に、電線接続部１２（即ち、圧接端子部３２。）を覆うように、ハウジング１０の上方からハウジング１０に装着固定される。圧接カバー４０は、矩形状に形成されたカバー本体部４１と、前側（即ち、カバー本体部４１におけるハウジング１０のバルブ装着部１１側。）に突出する電極保護部４２とを有している。カバー本体部４１には、その前後両端における左右両側に、ハウジング１０の係止突起１９を係止するための係止爪４３が形成されている。 As shown in FIG. 6, the pressure contact cover 40 is for protecting the pressure contact terminal portion 32 of the bus bar 30, and covers the wire connection portion 12 (that is, the pressure contact terminal portion 32) after the pressure contact of the electric wire 70. The housing 10 is mounted and fixed to the housing 10 from above. The pressure-contact cover 40 includes a cover main body portion 41 formed in a rectangular shape and an electrode protection portion 42 that protrudes to the front side (that is, the valve mounting portion 11 side of the housing 10 in the cover main body portion 41). Locking claws 43 for locking the locking projections 19 of the housing 10 are formed on the left and right sides of the front and rear ends of the cover main body 41.
　図４に示すように、電極保護部４２には、前側に嵌合溝（即ち、嵌合部。）４４が形成されている。この嵌合溝４４には、圧接カバー４０をハウジング１０へ装着することで、バスバー３０の位置決め板部３４の上方側の部分３４ｂが挿し込まれる。これにより、バスバー３０は、圧接カバー４０の嵌合溝４４で保持される。位置決め板部３４が嵌合溝４４の前後両端の壁部に突き当たることで、ハウジング１０の前後方向（即ち、図４における矢印Ａ方向。）への移動が規制される。さらに、位置決め板部３４の表裏面が嵌合溝４４の左右両側の壁面に当接することで、ハウジング１０の左右方向（即ち、図４における矢印Ｂ方向。）への移動が規制される。 As shown in FIG. 4, the electrode protection portion 42 has a fitting groove (that is, a fitting portion) 44 formed on the front side. By attaching the pressure contact cover 40 to the housing 10, the upper portion 34 b of the positioning plate portion 34 of the bus bar 30 is inserted into the fitting groove 44. As a result, the bus bar 30 is held in the fitting groove 44 of the pressure contact cover 40. When the positioning plate portion 34 abuts against the wall portions at both front and rear ends of the fitting groove 44, the movement of the housing 10 in the front-rear direction (that is, the direction of arrow A in FIG. 4) is restricted. Furthermore, when the front and back surfaces of the positioning plate portion 34 abut against the left and right wall surfaces of the fitting groove 44, the movement of the housing 10 in the left-right direction (that is, the arrow B direction in FIG. 4) is restricted.
　このように、圧接カバー４０をハウジング１０へ装着すると、図７及び図８に示すように、バスバー３０の位置決め板部３４は、その下方側の部分３４ａ及び上方側の部分３４ｂがハウジング１０及び電極保護部４２の嵌合溝１６，４４によって保持される。これにより、ハウジング１０の前後方向（即ち、矢印Ａ方向。）及び左右方向（即ち、矢印Ｂ方向。）への移動が規制される。 Thus, when the pressure contact cover 40 is attached to the housing 10, as shown in FIGS. 7 and 8, the positioning plate portion 34 of the bus bar 30 has a lower portion 34a and an upper portion 34b formed of the housing 10 and the electrode. It is held by the fitting grooves 16 and 44 of the protection part 42. Thereby, the movement of the housing 10 in the front-rear direction (that is, the arrow A direction) and the left-right direction (that is, the arrow B direction) is restricted.
　図９に示すように、電極保護部４２（後述するガイド部４８。）の左右両側部には、ロック爪（即ち、ロック部。）４５が形成されている。図１０に示すように、ロック爪４５は、圧接カバー４０をハウジング１０へ装着することで、ハウジング１０の係止板部１８（即ち、係止部。）の係止孔１７に入り込んで係止板部１８を係止する。これにより、電極保護部４２がハウジング１０の電線接続部１２における前側で保持される。そして、この圧接カバー４０がハウジング１０に装着されることで、カバー本体部４１によって、電線７０が配設されたバスバー３０の圧接端子部３２の上方が覆われて保護される。 As shown in FIG. 9, lock claws (that is, lock portions) 45 are formed on the left and right sides of the electrode protection portion 42 (a guide portion 48 described later). As shown in FIG. 10, the lock claw 45 is inserted into the locking hole 17 of the locking plate portion 18 (that is, the locking portion) of the housing 10 and locked by attaching the pressure contact cover 40 to the housing 10. The plate portion 18 is locked. Thereby, the electrode protection part 42 is hold | maintained in the front side in the electric wire connection part 12 of the housing 10. FIG. When the pressure contact cover 40 is attached to the housing 10, the cover main body 41 covers and protects the upper side of the pressure contact terminal portion 32 of the bus bar 30 on which the electric wires 70 are disposed.
　また、圧接カバー４０がハウジング１０に装着されると、図１１に示すように、電極保護部４２がバスバー３０の電極部３１の上部を覆うように配置され、電極部３１が保護される。これにより、バスバー３０の電極部３１は、その接点部３５の上下が、ハウジング１０の底板１５と圧接カバー４０の電極保護部４２とで囲われた状態となり、この接点部３５のバネ端子部３６が囲われた空間部分が挿入空間Ｓ（即ち、バルブ挿入空間。）とされる。即ち、電極保護部４２は、圧接カバー４０がハウジング１０に装着された際に、ハウジング１０の底板１５との間に画成される挿入空間Ｓにバネ端子部３６を位置付ける。 Further, when the pressure contact cover 40 is attached to the housing 10, as shown in FIG. 11, the electrode protection part 42 is arranged so as to cover the upper part of the electrode part 31 of the bus bar 30, and the electrode part 31 is protected. As a result, the electrode portion 31 of the bus bar 30 is in a state where the upper and lower sides of the contact portion 35 are surrounded by the bottom plate 15 of the housing 10 and the electrode protection portion 42 of the pressure contact cover 40, and the spring terminal portion 36 of the contact portion 35. A space portion surrounded by is an insertion space S (that is, a valve insertion space). That is, the electrode protection part 42 positions the spring terminal part 36 in the insertion space S defined between the pressure contact cover 40 and the bottom plate 15 of the housing 10 when the pressure contact cover 40 is attached to the housing 10.
　電極保護部４２は、図１１に示すように、基端側に、バネ端子部３６の上方を覆う過大変位防止部４６を有し、先端側に、当該過大変位防止部４６に連設されたガイド部４８を有している。これら過大変位防止部４６及びガイド部４８の機能については、後述する。ガイド部４８の内面には、図１１に示すようにＲ字状に湾曲した湾曲部４８ａが形成されている。 As shown in FIG. 11, the electrode protection part 42 has an excessive displacement prevention part 46 covering the upper side of the spring terminal part 36 on the base end side, and is connected to the excessive displacement prevention part 46 on the distal end side. The guide portion 48 is provided. The functions of the excessive displacement prevention unit 46 and the guide unit 48 will be described later. As shown in FIG. 11, a curved portion 48 a that is curved in an R shape is formed on the inner surface of the guide portion 48.
　バルブ５０は、いわゆるウェッジベース型の光源であり、電球部５１と、電球部５１に連設された板状のベース部５２と、ベース部５２の表面に設けられて電球部５１と電気的に接続するバルブ接点部５３とを有している。このバルブ５０は、バルブ接点部５３に給電されることで、電球部５１が発光する。 The bulb 50 is a so-called wedge base type light source, and is electrically connected to the light bulb portion 51 by providing the light bulb portion 51, a plate-like base portion 52 connected to the light bulb portion 51, and the surface of the base portion 52. And a valve contact portion 53 to be connected. The bulb 50 emits light when the bulb 50 is supplied with power to the bulb contact portion 53.
　このバルブ５０は、ベース部５２を挿入空間Ｓへ向けて前方側から挿し込むことで、ハウジング１０のバルブ装着部１１に装着される。これにより、ベース部５２が接点部３５のバネ端子部３６で挟持されてバルブ接点部５３にバネ端子部３６が導通接触される。即ち、一対のバネ端子部３６は、互いに接近する方向及び離反する方向に（即ち、上下方向において。）弾性変形してバルブ５０のベース部５２を挟持し、バルブ５０に電気的に接続する。 The valve 50 is mounted on the valve mounting portion 11 of the housing 10 by inserting the base portion 52 toward the insertion space S from the front side. As a result, the base portion 52 is clamped by the spring terminal portion 36 of the contact portion 35, and the spring terminal portion 36 is brought into conductive contact with the valve contact portion 53. That is, the pair of spring terminal portions 36 are elastically deformed in a direction approaching and separating from each other (that is, in the vertical direction) to sandwich the base portion 52 of the valve 50 and to be electrically connected to the valve 50.
　図１２に示すように、スイッチ２０は、絶縁樹脂製のスライダー２１と、このスライダー２１に形成された貫通孔２２に収容されるボール２３と、このボール２３の上部に配置されるスプリング２４と、スライダー２１に対して上方から組み付けられて装着される導電金属製のコンタクト２５とを備えている。スイッチ２０は、ハウジング１０におけるスイッチ装着部１３に形成されたスライド溝１３ａに収容され、ハウジング１０の左右方向（即ち、図４における矢印Ｂ方向。）において移動可能とされる。スライダー２１には、上方へ突出するつまみ部２６が形成されており、使用者は、このつまみ部２６を把持し、ハウジング１０に対してスイッチ２０を左右方向へ移動させることができる。 As shown in FIG. 12, the switch 20 includes an insulating resin slider 21, a ball 23 accommodated in a through hole 22 formed in the slider 21, a spring 24 disposed on the ball 23, A conductive metal contact 25 is mounted and mounted on the slider 21 from above. The switch 20 is accommodated in a slide groove 13a formed in the switch mounting portion 13 in the housing 10 and is movable in the left-right direction of the housing 10 (that is, in the direction of arrow B in FIG. 4). The slider 21 is formed with a knob portion 26 that protrudes upward. The user can hold the knob portion 26 and move the switch 20 in the left-right direction with respect to the housing 10.
　このスイッチ２０の上方には、バスバー３０のスイッチ端子部３３に設けられた複数の接点３７が配列されており、これら接点３７の上方側から絶縁樹脂製のスイッチカバー６０がハウジング１０のスイッチ装着部１３を覆うように組み付けられる。このとき、スイッチカバー６０は、スプリング２４を縮めた状態で組み付けられる。これにより、スイッチカバー６０が、コンタクト２５とスプリング２４とボール２３とを、スイッチ装着部１３との間に挟持した状態となる。 A plurality of contacts 37 provided on the switch terminal portion 33 of the bus bar 30 are arranged above the switch 20, and a switch cover 60 made of insulating resin is provided above the contacts 37 from the switch mounting portion of the housing 10. 13 so as to cover 13. At this time, the switch cover 60 is assembled in a state where the spring 24 is contracted. As a result, the switch cover 60 is in a state in which the contact 25, the spring 24, and the ball 23 are sandwiched between the switch mounting portion 13.
　このようなスイッチ２０では、つまみ部２６を把持してハウジング１０に対して左右方向へ移動させることで、コンタクト２５によって、左右のいずれかの接点３７と中央の接点３７とが導通される。図１２に示したスイッチ２０によれば、コンタクト２５とハウジング１０との間にスプリング２４による弾性反発力が作用するが、これらの間にボール２３が介されているため、スイッチ２０を左右に移動させる際にスライダー２１に作用する摩擦力を低減することができる。このため、使用者は小さい力で円滑にスイッチ２０を左右方向へ移動させることができる。 In such a switch 20, the left and right contacts 37 and the center contact 37 are electrically connected by the contact 25 by gripping the knob portion 26 and moving it in the left-right direction with respect to the housing 10. According to the switch 20 shown in FIG. 12, an elastic repulsion force is exerted between the contact 25 and the housing 10 by the spring 24, but since the ball 23 is interposed between them, the switch 20 is moved to the left and right. It is possible to reduce the frictional force that acts on the slider 21 during the operation. Therefore, the user can smoothly move the switch 20 in the left-right direction with a small force.
　次に、上記の室内照明灯１を組み立てる場合について説明する。図１３（ａ）～（ｄ）は、室内照明灯の組み立て工程を説明する図である。 Next, the case of assembling the above-described room illumination lamp 1 will be described. 13 (a) to 13 (d) are diagrams for explaining an assembly process of an indoor lamp.
　図１３（ａ）に示すように、ハウジング１０のスイッチ装着部１３に設けられたスライド溝１３ａに、スイッチ２０を収容する。 As shown in FIG. 13A, the switch 20 is accommodated in the slide groove 13 a provided in the switch mounting portion 13 of the housing 10.
　図１３（ｂ）に示すように、ハウジング１０の電線接続部１２に、その上方側からバスバー３０を装着すると共に、スイッチ装着部１３に、スイッチカバー６０を装着してバスバー３０の接点３７をスイッチカバー６０で覆う。 As shown in FIG. 13B, the bus bar 30 is mounted on the electric wire connecting portion 12 of the housing 10 from above, and the switch cover 60 is mounted on the switch mounting portion 13 to switch the contact point 37 of the bus bar 30 to the switch. Cover with a cover 60.
　このようにバスバー３０をハウジング１０の電線接続部１２に装着すると、バスバー３０の位置決め板部３４の下方側の部分３４ａがハウジング１０の嵌合溝１６に挿し込まれる。これにより、バスバー３０が位置決めされるとともに、ハウジング１０に対して前後左右方向への移動が規制された状態に保持される。 When the bus bar 30 is thus attached to the electric wire connection portion 12 of the housing 10, the lower portion 34 a of the positioning plate portion 34 of the bus bar 30 is inserted into the fitting groove 16 of the housing 10. Accordingly, the bus bar 30 is positioned and held in a state in which movement in the front-rear and left-right directions with respect to the housing 10 is restricted.
　図１３（ｃ）に示すように、ハウジング１０の電線接続部１２に装着されたバスバー３０の圧接端子部３２上に電線７０を配置させると共に、ハウジング１０に、その上方側から圧接カバー４０を組み付ける。 As shown in FIG. 13C, the electric wire 70 is arranged on the press contact terminal portion 32 of the bus bar 30 attached to the wire connection portion 12 of the housing 10, and the press contact cover 40 is assembled to the housing 10 from the upper side. .
　このように圧接カバー４０をハウジング１０に組み付けると、圧接カバー４０のカバー本体部４１によって電線７０がバスバー３０の圧接端子部３２に押し付けられる。これにより、電線７０が圧接刃３８に押し付けられて電線７０の導体が被覆から露出され、この電線７０の導体が圧接刃３８と接触する。これにより、所定の電線７０と所定のバスバー３０とが導通され、電線７０からの電力供給が可能とされる。また、圧接カバー４０のカバー本体部４１によってバスバー３０及び電線７０がハウジング１０に保持される。この状態で、カバー本体部４１は、その係止爪４３がハウジング１０の係止突起１９を係止する。これにより、カバー本体部４１がハウジング１０における電線接続部１２の上方を覆った状態に保持される。 When the pressure contact cover 40 is assembled to the housing 10 in this manner, the electric wire 70 is pressed against the pressure contact terminal portion 32 of the bus bar 30 by the cover main body portion 41 of the pressure contact cover 40. As a result, the electric wire 70 is pressed against the press contact blade 38 to expose the conductor of the electric wire 70 from the coating, and the conductor of the electric wire 70 comes into contact with the press contact blade 38. Thereby, the predetermined electric wire 70 and the predetermined bus bar 30 are electrically connected, and power supply from the electric wire 70 is enabled. Further, the bus bar 30 and the electric wire 70 are held in the housing 10 by the cover main body portion 41 of the pressure contact cover 40. In this state, the cover claw 43 of the cover main body 41 locks the locking projection 19 of the housing 10. Thereby, the cover main body 41 is held in a state of covering the upper portion of the wire connecting portion 12 in the housing 10.
　圧接カバー４０をハウジング１０に組み付けると、圧接カバー４０の電極保護部４２がハウジング１０におけるバルブ装着部１１の上部に配置される。これにより、ハウジング１０のバルブ装着部１１には、ハウジング１０の底板１５と電極保護部４２とで囲われた挿入空間Ｓが形成され、バスバー３０の接点部３５の上方及び下方が覆われる。 When the pressure contact cover 40 is assembled to the housing 10, the electrode protection part 42 of the pressure contact cover 40 is arranged on the upper part of the valve mounting part 11 in the housing 10. Thus, an insertion space S surrounded by the bottom plate 15 of the housing 10 and the electrode protection portion 42 is formed in the valve mounting portion 11 of the housing 10, and the upper and lower portions of the contact portion 35 of the bus bar 30 are covered.
　また、電極保護部４２の嵌合溝４４に、バスバー３０の位置決め板部３４の上方側の部分３４ｂが挿し込まれる。これにより、バスバー３０が位置決めされるとともに、ハウジング１０に対して前後左右方向への移動が規制された状態に保持される。 Further, the upper portion 34 b of the positioning plate portion 34 of the bus bar 30 is inserted into the fitting groove 44 of the electrode protection portion 42. Accordingly, the bus bar 30 is positioned and held in a state in which movement in the front-rear and left-right directions with respect to the housing 10 is restricted.
　また、電極保護部４２のロック爪４５がハウジング１０の係止板部１８の係止孔１７に入り込んで係止板部１８を係止する。これにより、電極保護部４２がハウジング１０の電線接続部１２におけるバルブ装着部１１側に確実に保持される。 Further, the lock claw 45 of the electrode protection part 42 enters the locking hole 17 of the locking plate part 18 of the housing 10 and locks the locking plate part 18. Thereby, the electrode protection part 42 is reliably hold | maintained at the valve | bulb mounting part 11 side in the electric wire connection part 12 of the housing 10. FIG.
　図１３（ｄ）に示すように、ハウジング１０の底板１５と圧接カバー４０の電極保護部４２とで囲われた挿入空間Ｓにベース部５２を挿し込むことで、バルブ５０をバルブ装着部１１に装着させる。このように、バルブ５０をバルブ装着部１１に装着させると、バルブ５０のベース部５２のバルブ接点部５３に、バスバー３０のバネ端子部３６が導通接触される。これにより、電線７０からバスバー３０を介してバルブ５０へ給電されることで、バルブ５０の電球部５１が発光することとなる。 As shown in FIG. 13 (d), the valve portion 50 is inserted into the valve mounting portion 11 by inserting the base portion 52 into the insertion space S surrounded by the bottom plate 15 of the housing 10 and the electrode protection portion 42 of the pressure contact cover 40. Install it. Thus, when the valve 50 is mounted on the valve mounting portion 11, the spring terminal portion 36 of the bus bar 30 is brought into conductive contact with the valve contact portion 53 of the base portion 52 of the valve 50. Thus, power is supplied from the electric wire 70 to the bulb 50 via the bus bar 30, so that the light bulb portion 51 of the bulb 50 emits light.
　ところで、バルブ５０のベース部５２を挿入空間Ｓへ挿し込む際に、バルブ５０が挿入空間Ｓへの正規な挿入角度よりも上下方向（即ち、図１１における矢印Ｃ方向。）に傾いた状態で挿入されることがある。即ち、バルブ５０の斜め挿入が発生する場合がある。このように、バルブ５０がベース部５２側から挿入空間Ｓに挿入されてバネ端子部３６に接続される際に、バルブ５０が正規な挿入角度よりも傾いていると、ベース部５２等がバネ端子部３６に当接して当該バネ端子部３６を上方側（即ち、圧接カバー４０側。）に過大変位させてしまう虞がある。バネ端子部３６が過大変位すると、バネ端子部３６が塑性変形することによって、バルブ５０とバスバー３０との良好な導通接触状態が損なわれてしまう虞がある。 By the way, when the base portion 52 of the valve 50 is inserted into the insertion space S, the valve 50 is inclined in the vertical direction (that is, in the direction of arrow C in FIG. 11) with respect to the normal insertion angle into the insertion space S. May be inserted. In other words, the valve 50 may be inserted obliquely. Thus, when the valve 50 is inclined from the normal insertion angle when the valve 50 is inserted into the insertion space S from the base portion 52 side and connected to the spring terminal portion 36, the base portion 52 and the like are spring-loaded. There is a risk that the spring terminal portion 36 may be excessively displaced upward (ie, on the pressure contact cover 40 side) by contacting the terminal portion 36. If the spring terminal portion 36 is excessively displaced, the spring terminal portion 36 may be plastically deformed, so that a good conductive contact state between the valve 50 and the bus bar 30 may be impaired.
　これに対して、本実施形態では、圧接カバー４０が電極保護部４２を有し、当該電極保護部４２が基端側に過大変位防止部４６を有している。このため、バルブ５０がベース部５２側から挿入空間Ｓに挿入されてバネ端子部３６に接続される際に、バルブ５０が正規な挿入角度よりも所定の角度だけ傾いており、これによりベース部５２等がバネ端子部３６に当接して当該バネ端子部３６を上方側に過大変位させようとした場合には、過大変位防止部４６が過大変位しようとしたバネ端子部３６に当接して当該過大変位を防止する。即ち、本実施形態では、過大変位防止部４６によってバネ端子部３６の過大変位領域への変位が規制されている。したがって、バルブ装着部１１へバルブ５０を装着させる際におけるバネ端子部３６の上方側への過大変位が防止されている。このため、バルブ５０のベース部５２のバルブ接点部５３と、バスバー３０のバネ端子部３６との良好な導通接触状態を維持することができ、バルブ５０とバスバー３０との接続の信頼性を向上させることができる。
　尚、バネ端子部３６の下方側への過大変位は、ハウジング１０の底板１５によって防止されている。 On the other hand, in this embodiment, the press-contact cover 40 has the electrode protection part 42, and the electrode protection part 42 has the excessive displacement prevention part 46 on the proximal end side. For this reason, when the valve 50 is inserted into the insertion space S from the base portion 52 side and connected to the spring terminal portion 36, the valve 50 is inclined by a predetermined angle from the normal insertion angle. When 52 or the like abuts against the spring terminal portion 36 and excessively displaces the spring terminal portion 36 upward, the excessive displacement preventing portion 46 contacts the spring terminal portion 36 about to be excessively displaced. The excessive displacement is prevented in contact. In other words, in the present embodiment, the displacement of the spring terminal portion 36 to the excessive displacement region is regulated by the excessive displacement prevention portion 46. Therefore, excessive displacement of the spring terminal portion 36 to the upper side when the valve 50 is mounted on the valve mounting portion 11 is prevented. For this reason, the favorable contact state between the valve contact portion 53 of the base portion 52 of the valve 50 and the spring terminal portion 36 of the bus bar 30 can be maintained, and the reliability of the connection between the valve 50 and the bus bar 30 is improved. Can be made.
An excessive displacement of the spring terminal portion 36 in the downward direction is prevented by the bottom plate 15 of the housing 10.
　また、本実施形態のハウジング１０は、バルブ装着部１１の上方が開放されているため、バルブ５０は、電球部５１がベース部５２に対して上方に傾いた状態で挿入空間Ｓへ挿し込まれ易い。このように電球部５１がベース部５２に対して上方に傾いた状態でバルブ５０が挿入空間Ｓへ挿し込まれた場合には、バネ端子部３６の上方側への過大変位が発生し易い。
　これに対して、本実施形態では、バネ端子部３６の上方側に過大変位防止部４６が配置されているために、正規な挿入角度よりも所定の角度だけ電球部５１がベース部５２に対して上方側に傾いた状態でバルブ５０が挿入空間Ｓに挿入され、これによりバネ端子部３６が上方側に過大変位しようとした場合に、過大変位防止部４６がバネ端子部３６に当接して当該過大変位が防止される。 Further, since the housing 10 of the present embodiment is open above the bulb mounting portion 11, the bulb 50 is inserted into the insertion space S with the bulb portion 51 tilted upward with respect to the base portion 52. easy. Thus, when the bulb 50 is inserted into the insertion space S in a state where the bulb portion 51 is tilted upward with respect to the base portion 52, excessive displacement of the spring terminal portion 36 to the upper side is likely to occur. .
On the other hand, in this embodiment, since the excessive displacement prevention part 46 is disposed above the spring terminal part 36, the light bulb part 51 is attached to the base part 52 by a predetermined angle from the normal insertion angle. On the other hand, when the valve 50 is inserted into the insertion space S in a state of being inclined upward, the excessive displacement preventing portion 46 is moved to the spring terminal portion 36 when the spring terminal portion 36 is about to be excessively displaced upward. The excessive displacement is prevented by contact.
　また、電極保護部４２は、過大変位防止部４６に連設された、湾曲部４８ａが形成されたガイド部４８を更に有している。このため、バルブ５０が正規な角度よりも傾いて挿入空間Ｓに挿入されようとした際に、ベース部５２の先端がガイド部４８（特に、湾曲部４８ａ。）に摺接されることにより案内され、これによりバルブ５０の挿入角度が正規なものとされる。この結果、バルブ５０の斜め挿入が防止される。このため、正規な挿入角度よりも傾いた状態でバルブ５０が挿入空間Ｓに挿し込まれる事象の発生を抑制でき、バネ端子部３６の過大変形を抑制することができる。 The electrode protection part 42 further includes a guide part 48 formed with a curved part 48 a that is connected to the excessive displacement prevention part 46. For this reason, when the valve 50 is about to be inserted into the insertion space S at an angle more than a normal angle, the tip of the base portion 52 is guided by being brought into sliding contact with the guide portion 48 (particularly, the curved portion 48a). Thus, the insertion angle of the valve 50 is made normal. As a result, the oblique insertion of the valve 50 is prevented. For this reason, it is possible to suppress the occurrence of an event in which the valve 50 is inserted into the insertion space S in a state tilted from the normal insertion angle, and it is possible to suppress excessive deformation of the spring terminal portion 36.
　以上説明したように、本実施形態に係る室内照明灯１によれば、バネ端子部３６における過大変位の発生を抑制できる。 As described above, according to the indoor lamp 1 according to the present embodiment, it is possible to suppress the occurrence of excessive displacement in the spring terminal portion 36.
　以下では、実施形態に係る室内照明灯１について纏める。 In the following, the interior lighting 1 according to the embodiment will be summarized.

It further includes a bus bar 30 that has a pair of spring terminal portions 36 that are sandwiched and electrically connected to the valve 50 and that is attached to the housing 10. In addition, the interior lighting lamp 1 includes a pressure contact terminal portion after the bus bar 30 is mounted on the housing 10 and the electric wire 70 is pressure connected to the pressure contact terminal portion 32 and before the bulb 50 is connected to the spring terminal portion 36. Further, a pressure contact cover 40 attached to the housing 10 is further provided so as to cover 32. The pressure contact cover 40 has an electrode protection portion 42 that positions the spring terminal portion 36 in an insertion space S (valve insertion space) defined between the pressure contact cover 40 and a part of the housing 10 when the pressure contact cover 40 is attached to the housing 10. It has further. When the bulb 50 is inserted into the insertion space S from the base portion 52 side and connected to the spring terminal portion 36, the electrode protection portion 42 is inserted with an inclination of a normal insertion angle (oblique insertion).

　例えば、本実施形態では、電極保護部４２のうちのガイド部４８に、ロック爪４５（即ち、ロック部。）が形成されている構成としたが、電極保護部４２のうちの過大変位防止部４６に形成されている構成としても構わない。但し、ガイド部４８にロック爪４５を形成した方が、他の圧接カバー４０のハウジング１０に対する係止機構である、係止爪４３と係止突起１９との係止部分からの距離を長くすることができ、圧接カバー４０をハウジング１０に対して確実に装着することができる。特に、電極保護部４２に上向きの力が作用した場合における保持力を向上することができる。 For example, in this embodiment, the lock claw 45 (that is, the lock portion) is formed in the guide portion 48 of the electrode protection portion 42, but excessive displacement prevention of the electrode protection portion 42 is performed. The structure formed in the portion 46 may be used. However, when the locking claw 45 is formed on the guide portion 48, the distance from the locking portion between the locking claw 43 and the locking projection 19, which is a locking mechanism for the other pressure contact cover 40 to the housing 10, is increased. The pressure contact cover 40 can be securely attached to the housing 10. In particular, the holding force when an upward force is applied to the electrode protection part 42 can be improved.
　また、本実施形態では、バスバー３０が、電線７０と接続するための端子部として圧接端子部３２を備え、バスバー３０と電線７０とが圧接接続される構成としたが、タブ端子を用いた接続やコネクタ接続等の他の接続方法によりバスバー３０と電線７０とが電気的に接続される構成としても構わない。 Further, in this embodiment, the bus bar 30 includes the press contact terminal portion 32 as a terminal portion for connecting to the electric wire 70, and the bus bar 30 and the electric wire 70 are connected by press contact. However, the connection using the tab terminal is used. Alternatively, the bus bar 30 and the electric wire 70 may be electrically connected by other connection methods such as connector connection.
