Description
【発明の詳細な説明】 本発明は安定器の安全装置に係る。[Detailed description of the invention] The present invention relates to a safety device for a ballast.
一般に安定器は、螢光灯等を点灯するものであるが、安
定器自体が故障すると高温となわ、遂には発火すること
がある。Generally, ballasts are used to light up fluorescent lights, etc., but if the ballast itself malfunctions, the temperature may rise and eventually catch fire.
かかる安定器が異常時でも照明器具の本体に取付られた
ままであると、その安定器の取付場所近辺に取付られた
電気部品までも著るし＜損傷を受けるばかりか、火災等
の原因になり非常に危険である。If such a ballast remains attached to the main body of the lighting equipment even during abnormal conditions, electrical components installed near the ballast's installation location may be damaged and may even cause a fire. Very dangerous.
本発明はかかる点に鑑みて成したもので、安定器異常時
に自動的に電源を切断して上記の如き危険を防止せんと
する安全装置を提供せんとするにある。The present invention has been made in view of this problem, and it is an object of the present invention to provide a safety device that automatically cuts off the power supply in the event of an abnormality in the ballast to prevent the above-mentioned dangers.
以下、本発明を実施例につき詳述すれば、第１図におい
て、１は安定器で、その側部からは取付部２を突設して
いる。Hereinafter, the present invention will be described in detail with reference to an embodiment. In FIG. 1, reference numeral 1 denotes a stabilizer, and a mounting portion 2 is provided protruding from the side thereof.
３はネジでその頭部は照明器具本体４の上部へ突出し、
中央部は取付部２の取付孔２ａに挿入されて、下端には
ナット５を螺合している。3 is a screw whose head protrudes to the top of the lighting device body 4;
The central part is inserted into the mounting hole 2a of the mounting part 2, and a nut 5 is screwed into the lower end.
６は、スペーサーで、熱可塑性樹脂５ 例えば、アクリ
ル、ナイロン等で筒状をなし、前記ネジ３の外周に挿通
されている。A spacer 6 is made of thermoplastic resin 5, such as acrylic or nylon, and has a cylindrical shape, and is inserted around the outer periphery of the screw 3.
Ｔは下部端子で接触部Ｔａを内蔵し該接触部Ｔａにはリ
ード線８が接続されている。T is a lower terminal which has a built-in contact portion Ta, and a lead wire 8 is connected to the contact portion Ta.
９は上部端子で受部９ａを内蔵し、該受部９ａには電源
線１０１０が接続されている。Reference numeral 9 denotes an upper terminal which includes a receiving portion 9a, and a power line 1010 is connected to the receiving portion 9a.
而して、下部端子７は安定器１の上面に取付られ、上部
端子９は照明器具本体４の下面に取付られている。Thus, the lower terminal 7 is attached to the upper surface of the ballast 1, and the upper terminal 9 is attached to the lower surface of the lighting fixture body 4.
従つて、ネジ３及びナット５とで安定器１を照明器具本
体４に取付たときは、前記接触１５部７ａと、受部９ａ
とが接合するよう構成されている。また、安定器１の重
量がスペーサー６で支持されていないときは、接触部７
ａと受部９ａとの接合は分離される。いま、安定器１が
通常の状態で使用されている２０ときには、安定器１か
ら発生する熱は、安定器１と密接して取付られた照明器
具本体４に伝達されるので放熱効果がある。Therefore, when the ballast 1 is attached to the lighting fixture body 4 with the screws 3 and nuts 5, the contact 15 portion 7a and the receiving portion 9a
It is configured so that the two are connected. In addition, when the weight of the stabilizer 1 is not supported by the spacer 6, the contact portion 7
The connection between a and the receiving portion 9a is separated. Now, when the ballast 1 is used in a normal state 20, the heat generated from the ballast 1 is transferred to the lighting fixture body 4 which is attached closely to the ballast 1, so that it has a heat dissipation effect.
しかるに、安定器１に故障が生じた場合は、安定器１に
は異常電流が流れ、異常な発熱を起す。However, if a failure occurs in the ballast 1, an abnormal current flows through the ballast 1, causing abnormal heat generation.
２５従つて、ネジ３の部分も高温となるが、スペーサー
６は熱可塑性樹脂で形成されているので、その溶融点を
越えるとスペーサー６は溶融し、所期の長さを維持しえ
なくなる。25 Therefore, the screw 3 part also becomes high temperature, but since the spacer 6 is made of thermoplastic resin, if the melting point is exceeded, the spacer 6 will melt and will not be able to maintain the desired length.
安定器１は、通常鉄板やコイルによシ形成されているの
で、その重量を３０支えきれなくなると、安定器１は下

障が生じ異常に温度上昇することがあつても、スペーサ
ーが溶解して安定器は落下し、安定器への電源接続部を
分離して、安定器への電源供給を中止させることができ
る。Since the ballast 1 is usually formed of an iron plate or a coil, when the ballast 1 is no longer able to support the weight of the ballast 1, the ballast 1 moves downward. Therefore, the weight of the ballast 1 separates the connection between the contact portion 7a and the receiving portion 9a, and power supply to the ballast 1 is stopped. Therefore, the temperature of the ballast 1 is lowered, and damage 35 to the lighting fixture body 1 due to abnormal heat generation due to failure can be prevented. Thus, the safety device of the ballast of the present invention is
A screw hanging from the lower surface of the lighting equipment body is inserted into the mounting hole of the ballast, and a spacer made of thermoplastic resin is provided between the nut screwed into the lower end of the screw and the lower surface of the periphery of the mounting hole. The power connection part, which should be separated due to the weight of the ballast in the event of a ballast abnormality, is attached to the joint between the lighting equipment body and the ballast. If the temperature were to rise even further, the spacer would melt and the ballast would fall, allowing the power connection to the ballast to be disconnected and power to the ballast to be removed.
従つて、安定器故障による損傷を照明器具本体に及ぼす
ことなく安全に使用しうる効果がある。Therefore, there is an effect that the luminaire can be used safely without causing damage to the luminaire body due to ballast failure.
