〔発明の目的〕
（産業上の利用分野）
本発明は、例えば施設照明等に用いられる天井あるいは
壁埋込形照明器具の端子台取付手段に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a terminal block mounting means for a ceiling- or wall-embedded lighting fixture used, for example, in facility lighting.
（従来の技術）
例えばクリ１トンランプ等点灯時、高熱を伴うランプを
用いる埋込形照明器具は、器具の諸部への熱影響が大き
く、従って、様々な熱対策がなされている。ハウジング
の天板上に設けられる端子台もそのうちの一つである。(Prior Art) Recessed lighting equipment that uses a lamp that generates high heat when turned on, such as a Kurilton lamp, has a large thermal effect on various parts of the equipment, and therefore various heat countermeasures have been taken. One of them is a terminal block provided on the top plate of the housing.
ランプ点灯時ランプの熱が天板を通して端子台に伝導す

題があった。この問題の対策として、基準温度を３０℃
とすると６０℃以上の温度上昇を起すものは商品として
認可されないという規格がある（日本照明器具工業会：
技術資料１０９） 。When the lamp is turned on, when the heat from the lamp is conducted through the top plate to the terminal block, for example, the brass terminal provided in the terminal section will oxidize at about 90°C and its resistance will increase, resulting in heat generation and the connection to the terminal. There was a problem in that the insulating coating of the F cable was melted, causing a short circuit, which could result in sparks flying and causing a fire. As a countermeasure to this problem, the standard temperature was set to 30℃.
Accordingly, there is a standard that says that anything that causes a temperature rise of 60℃ or more will not be approved as a product (Japan Lighting Industry Association:
Technical data 109).

。In order to satisfy this standard, the Utility Model Sho 6 shown in Figure 10
1-39815 has been proposed. This is a downlight, and the terminal block mounting plate 82 with the terminal block 81 attached is placed against the top plate part 84 of the appliance main body 83.
The space 85 between the terminal block mounting plate 82 and the top plate portion 84 is installed in a sliding manner so as to communicate with the outside, so that the heat from the lamp is blocked by the space 85.
（従来の問題点）
しかしながらこのものは、天板部８４と端子台取付板８
５との接触部分の熱伝導を考慮していない。(Problems with the conventional method) However, in this case, the top plate part 84 and the terminal block mounting plate 8
Heat conduction at the contact portion with 5 is not taken into account.

熱樹脂を設けることが考えられるが、材料費および作業
工程が増す問題があった。As shown in FIG. 10, there are two rectangular contact portions extending in the longitudinal direction. From lamp to terminal block 81
Since most of the heat that can affect the terminal block is once absorbed by the top plate section, there is a problem that even if the space 85 is provided, the heat is conducted through the contact section and has an adverse effect on the terminal block 81. . In order to block this heat, it has been considered to provide a heat insulating resin at the contact portion, but this has the problem of increasing material costs and work steps.

部材２０に与える熱影響は極めて少ない。As the lamp 3 is turned on, the lamp 3 generates heat. A part of this heat is conducted to the housing 1 through the reflecting mirror 6, the socket base 5, etc. A portion of the heat of this housing 1 is conducted to the terminal block mounting member 20, but since the only contact parts between the top plate 2 and this terminal block mounting member are the screws 23 and the tips of the protrusions 30, it is better than the conventional one. Most of the heat of the housing is emitted from the back surface of the housing 1 as radiant heat. The radiant heat naturally reaches the terminal block mounting member 20, but due to the air layer between the projection 20 and the upper end of the terminal block mounting member 20 and the top plate 2, the thermal effect on the terminal block mounting member 20 is small. Very few.
