【発明の属する技術分野】
本体に嵌合係止される反射板を有するトラフ形器具において、反射板を嵌合取付しただけで本体と反射板の電気的な接続を可能とする本体および反射板の取付構造に関するものである。
【０００２】
【従来の技術】
従来の技術においては、略コ字形の反射板の長手両端部を折り曲げ、本体の下端のカール部または段付け部に嵌合係止する取付け方式が一般的であり、反射板と本体間の電気的な接合に関しては特に配慮されていないため、本体と反射板の保護接地（アース）の連続性が得られない問題があった。
【０００３】
【発明が解決しようとする課題】
本発明は、上記従来技術の問題点を解決するため、ソケット台の一部に１個または複数個の突起を設け、本体の両端部に嵌合係止したときに本体の側面にわずかに突出する構成とした。この状態の本体に略コ字形の反射板を嵌合係止させるだけで特に金具等を用いず容易に本体と反射板の電気的な接続を可能として、保護接地（アース）の連続性を得ることを目的とするものである。

【課題を解決するための手段】
下面を開放した本体１、本体に取り付られる点灯装置２、本体長手方向の両端面を閉じランプソケット４を保持するソケット台３、点灯装置２や内部配線を覆うとともに蛍光ランプ５からの光を有効的に反射させる反射板６とを備えた蛍光灯器具において、ソケット台３の一部に嵌合係止片３２、本体１の反射板取付部１２よりわずかに突き出る寸法の導通用突起３３を備え、本体の長手側面に嵌合部１２と嵌合係止片３２，導通用突起３３に対応する位置に嵌合穴１１を備え、略コ字形反射板６には立ち上がり部６１の内側を折り返した６２を備えた構成とした。
ソケット台３は本体嵌合穴１１に嵌合後、嵌合係止片３２を折り曲げることで本体に固定される。このとき導通用突起３３は本体の反射板取付部１２よりわずかに突き出ている。この状態で反射板６の立ち上がり部６１を本体の反射板取付部１２に挿入していくと、本体よりわずかに突き出た突起３３に反射板の折り曲げ部６２が当接しながら嵌合係止し、反射板の防錆用の塗膜が剥離され本体１と反射板６の電気的な接続が容易にかつ確実に得られる構成とした。反射板６と本体１の嵌合は反射板の立ち上がり部６１の弾発力により確実に軽視されるため、本体と反射板の保護接地の連続性が得られる蛍光灯器具を提供することができる。

ソケット台３は本体嵌合穴１１に嵌合後、嵌合係止片３２を折り曲げることで本体に固定される。このとき導通用突起３３は本体の反射板取付部１２よりわずかに突き出ている。この状態で反射板６の立ち上がり部６１を本体の反射板取付部１２に挿入していくと、本体よりわずかに突き出た突起３３に反射板の折り曲げ部６２が当接しながら嵌合係止し、反射板の防錆用の塗膜が剥離され本体１と反射板６の電気的な接続が容易にかつ確実に得られる構成とした。反射板６と本体１の嵌合は反射板の立ち上がり部６１の弾発力により確実に軽視されるため、特別な部品を必要とせず，従来と同じ反射板取付操作のみで容易にかつ確実な本体と反射板の保護接地の連続性が得られる、また、導通用突起３３は反射板６により覆われ外観上に現れないため美観を損なうことがない蛍光灯器具を提供することができる。
【０００６】
【発明の効果】
本体１のに反射板６を嵌合係止する従来と同一の組立操作のみで施工性も従来と同等で、本体側面よりわずかに突き出した導通用突起３３により、本体１と反射板６の電気的な接続が得られ、保護接地（アース）の連続性が容易にかつ確実に得られ経済的でより安全な器具を提供できる。また、導通用突起３３は反射板６により覆われ外観上に現れないため美観を損なうことがない蛍光灯器具を提供することができる。
さらに、本体と反射板の保護接地（アース）の連続性により、電子安定器化に伴う雑音端子電圧や放射ノイズの抑制効果が得られ、信頼性の高い蛍光灯器具の提供が可能となる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trough-shaped device having a reflector fitted and locked to a main body, and to a main body and a reflector mounting structure which enable electrical connection between the main body and the reflector only by fitting the reflector. .
[0002]
[Prior art]
In the prior art, a mounting method is generally used in which both longitudinal ends of a substantially U-shaped reflector are bent and fitted and locked in a curl portion or a stepped portion at the lower end of the main body. There is a problem that continuity of the protective grounding (earth) between the main body and the reflector cannot be obtained because special consideration is not given to a typical joining.
[0003]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention provides one or more projections on a part of a socket base, and slightly protrudes from a side surface of the main body when fitted at both ends of the main body. Configuration. By simply fitting and engaging a substantially U-shaped reflector to the main body in this state, electrical connection between the main body and the reflector can be easily performed without using any metal fittings or the like, thereby obtaining continuity of protective grounding (earth). It is intended for that purpose.
[0004]
[Means for Solving the Problems]
A main body 1 having an open lower surface, a lighting device 2 attached to the main body, a socket base 3 which closes both end surfaces in a longitudinal direction of the main body to hold a lamp socket 4, and covers the lighting device 2 and the internal wiring and emits light from the fluorescent lamp 5. In a fluorescent lamp device provided with a reflecting plate 6 for effectively reflecting light, a fitting locking piece 32 and a conduction projection 33 having a size slightly protruding from the reflecting plate mounting portion 12 of the main body 1 are provided on a part of the socket base 3. A fitting hole 11 is provided at a position corresponding to the fitting portion 12, the fitting locking piece 32, and the conduction projection 33 on the longitudinal side surface of the main body, and the inside of the rising portion 61 is folded back on the substantially U-shaped reflection plate 6. 62.
After the socket base 3 is fitted into the main body fitting hole 11, the fitting lock piece 32 is bent to be fixed to the main body. At this time, the conductive projection 33 slightly protrudes from the reflector attaching portion 12 of the main body. In this state, when the rising portion 61 of the reflector 6 is inserted into the reflector attaching portion 12 of the main body, the bent portion 62 of the reflector is fitted and locked while abutting on the projection 33 slightly protruding from the main body, The rust-preventive coating film on the reflector was peeled off, and the electrical connection between the main body 1 and the reflector 6 was easily and reliably obtained. Since the fitting between the reflector 6 and the main body 1 is surely neglected by the resilience of the rising portion 61 of the reflector, it is possible to provide a fluorescent lamp apparatus in which the continuity of the protective grounding between the main body and the reflector can be provided. .

Embodiment of the present invention
A main body 1 having an open lower surface, a lighting device 2 attached to the main body, a socket base 3 which closes both end surfaces in a longitudinal direction of the main body to hold a lamp socket 4, and covers the lighting device 2 and the internal wiring and emits light from the fluorescent lamp 5. In a fluorescent lamp device provided with a reflecting plate 6 for effectively reflecting light,
A part of the socket base 3 is provided with a fitting and locking piece 32 and a conduction projection 33 having a size slightly protruding from the reflector attaching portion 12 of the main body 1. The fitting holes 11 are provided at positions corresponding to the pieces 32 and the conduction projections 33, and the substantially U-shaped reflection plate 6 is provided with 62 having the inside of the rising portion 61 turned back.
After the socket base 3 is fitted into the main body fitting hole 11, the fitting lock piece 32 is bent to be fixed to the main body. At this time, the conductive projection 33 slightly protrudes from the reflector attaching portion 12 of the main body. In this state, when the rising portion 61 of the reflector 6 is inserted into the reflector attaching portion 12 of the main body, the bent portion 62 of the reflector is fitted and locked while abutting on the projection 33 slightly protruding from the main body, The rust-preventive coating film on the reflector was peeled off, and the electrical connection between the main body 1 and the reflector 6 was easily and reliably obtained. Since the fitting between the reflector 6 and the main body 1 is reliably neglected by the resilience of the rising portion 61 of the reflector, no special parts are required, and the reflector plate can be easily and reliably mounted only by the same reflector mounting operation as before. The continuity of the protective grounding between the main body and the reflection plate can be obtained, and the fluorescent lamp device which does not impair the aesthetic appearance can be provided because the conduction projection 33 is covered with the reflection plate 6 and does not appear on the external appearance.
[0006]
【The invention's effect】
Only the same assembling operation as before in which the reflection plate 6 is fitted and locked to the main body 1 has the same workability as the conventional one, and the electrical connection between the main body 1 and the reflection plate 6 is provided by the conduction projection 33 slightly protruding from the side surface of the main body. , The continuity of the protective earth (earth) can be easily and reliably obtained, and an economical and safer instrument can be provided. In addition, since the projection 33 for conduction is covered with the reflection plate 6 and does not appear on the external appearance, it is possible to provide a fluorescent lamp apparatus which does not impair the aesthetic appearance.
Furthermore, due to the continuity of the protective grounding (earth) between the main body and the reflector, the effect of suppressing the noise terminal voltage and radiation noise accompanying the electronic ballast can be obtained, and a highly reliable fluorescent lamp device can be provided.
