Description
【０００１】[0001]
本考案は、天井面などに設置される火災感知器に関し、特に火災感知器、ある いは感知器ベースに設けられる導線接続部に関する。 The present invention relates to a fire detector installed on a ceiling surface or the like, and more particularly to a fire detector or a lead wire connecting portion provided on a detector base.
【０００２】[0002]
従来、火災感知器を天井面に取り付ける場合、取付ねじによりベースの導電金 具に螺着されている接続ネジを緩め、その間に電源線や信号線となって受信機や 中継器に接続されている導線を挟み込んで締め付けた後、感知器本体を装着して いる。近年、感知器は小型化、簡素化が進められていて、上記導線接続部も例外 ではない。 Conventionally, when mounting a fire detector on the ceiling surface, loosen the connection screw that is screwed to the conductive metal fitting of the base with the mounting screw, and connect it to the receiver or repeater as a power line or signal line between them. After sandwiching and tightening the conducting wire, the sensor body is attached. In recent years, sensors have been downsized and simplified, and the above-mentioned lead wire connection is no exception.
【０００３】 導線接続部は、通常、有蓋筒状のベースの内部に設けられていて、導線の引出 口とともに蓋部の大部分を占めている。この導線接続部をベースの背面、即ち、 天井面側に設ければ、引出口も必要なくなり、特に埋込型のベースにおいて都合 がよい。The lead wire connecting portion is usually provided inside a cylindrical base with a lid, and occupies most of the lid portion together with the lead wire outlet. If this conductor connecting portion is provided on the back surface of the base, that is, on the ceiling surface side, no outlet is required, which is particularly convenient for an embedded base.
【０００４】[0004]
しかし、ベースの背面に導線接続部のような導電部分を設けると漏水や埃等に より、断線や短絡したりする種々の不都合が考えられ、導電部分が露出しないよ うに保護しない限り実用できない。 However, if a conductive portion such as a conductive wire connection portion is provided on the back surface of the base, various inconveniences such as disconnection or short circuit due to water leakage or dust can be considered, and it cannot be used unless the conductive portion is protected so as not to be exposed.
【０００５】 本体とベースに分かれていない感知器の場合には、その背面に導線接続部を設 けているものもあるが、内部の電気回路部分からリード線を引き出して、外部の 導線をテーピングする場合が多く面倒である。In the case of a sensor which is not divided into a main body and a base, there is a sensor which has a lead wire connecting portion on the back surface thereof, but a lead wire is pulled out from an internal electric circuit portion to tap an external lead wire. It is often troublesome.
【０００６】 通常のベースの内部に導線接続部が設けられている場合にも、漏水や埃等から 保護されている方が安全であり、特に導線を端子板と係止ばねとの間に挟持して いる場合にはその部分で断線しやすく重要である。Even when a conductor connecting portion is provided inside a normal base, it is safer to be protected from water leakage, dust, etc., and particularly, the conductor is clamped between the terminal plate and the locking spring. If so, it is important that the part is easily broken.
【０００７】 この考案は、上記事情に鑑み、火災感知器の導線接続部を保護するとともに導 線の着脱を容易に行なうことを目的とする。In view of the above circumstances, the present invention aims to protect the conductor connecting portion of the fire detector and to easily attach and detach the conductor.
【０００８】[0008]
この考案は、端子板と端子ばねの係止片との間に導線を挿入して挟持する導線 接続部を備えた火災感知器において、該導線接続部を、導線の挿入孔付端子カバ ーで覆うとともに、該端子カバーに前記係止片と対向する解錠穴を設けたことを 特徴とする火災感知器、により前記目的を達成しようとするものである。 This invention relates to a fire detector having a lead wire connecting portion for inserting and holding a lead wire between a terminal plate and a locking piece of a terminal spring, wherein the lead wire connecting portion is a terminal cover with a lead wire insertion hole. It is an object of the present invention to achieve the above object by a fire detector characterized in that the terminal cover is provided with an unlocking hole facing the locking piece while covering the terminal cover.
【０００９】[0009]
導線接続部を端子カバーで覆うことにより天井裏等での水滴が金具に落ちたり 、埃が金具の上に積もったりせず、メンテ作業等において、不意に金具に接触し て短絡させることもない。又、端子カバーに導線の挿入孔と解錠穴とを設けたの で、該端子カバーを外すことなく、導線の着脱を容易に行なうことができる。 By covering the conductor connection with the terminal cover, water drops on the ceiling and the like will not fall on the metal fittings, and dust will not accumulate on the metal fittings, and during maintenance work etc., it will not accidentally contact the metal fittings and cause a short circuit. . Further, since the lead wire insertion hole and the unlock hole are provided in the terminal cover, the lead wire can be easily attached and detached without removing the terminal cover.
