Description

本発明は、天井や床下配線に使用するジョイントボックスに関するものである。  The present invention relates to a joint box used for ceiling or underfloor wiring.

従来、天井や床下配線に使用するジョイントボックスにおいては、図９及び図１０に示すように器台５０に設けた複数条の分岐導体収納溝５１内に分岐導体５３を収納すると共に、複数条の電源導体収納溝５２内に両端部に鎖錠バネ５８を収納した電源導体５４を収納し、接続すべき導体相互を中間接続導体５５により電気的に接続し、蓋体５６に設けた解錠釦嵌装口５７内に前記電源導体５４の両端部に収納された鎖錠バネ５８により鎖錠された電線導体を解錠する解錠釦５９を嵌装して構成されていた。しかしながら、上記、ジョイントボックスにおいては、ジョイントボックスの器台５０に収納された電源導体５４に電線が確実に挿入され鎖錠バネ５８により抜け止めされたか否かを目視により確認することができないために、不完全接続により発熱したり、使用中に電線が抜け出る惧れがある等の問題点があった。  Conventionally, in joint boxes used for ceiling and underfloor wiring, as shown in FIGS. 9 and 10, branch conductors 53 are housed in a plurality of branch conductor housing grooves 51 provided in the instrument base 50, and A power supply conductor 54 in which locking springs 58 are housed in both ends is housed in the power conductor housing groove 52, conductors to be connected are electrically connected by an intermediate connection conductor 55, and an unlock button provided on the lid 56 An unlocking button 59 for unlocking a wire conductor locked by a locking spring 58 housed at both ends of the power supply conductor 54 is fitted in the fitting port 57. However, in the above joint box, it is impossible to visually confirm whether or not the electric wire is securely inserted into the power supply conductor 54 housed in the joint box base 50 and prevented from being pulled out by the locking spring 58. There have been problems such as heat generation due to incomplete connection and the possibility of electric wires coming out during use.

上記問題点を解決する手段として図１１に示すように、器台６０に設けた電源導体収納溝６１内に収納される電源導体６２内に、一対の電線挿入確認駒６３ａ、６３ａ間をコイルスプリング６３ｂで連結した電線挿入確認部材６３を摺動自在に嵌装すると共に、蓋体６４に確認窓孔６５を穿設し、電源導体６２に電線が確実に挿入鎖錠されたか否かを目視により確認し得るように構成されたジョイントボックスが知られている。  As a means for solving the above problem, as shown in FIG. 11, a coil spring is interposed between a pair of electric wire insertion confirmation pieces 63a and 63a in a power supply conductor 62 accommodated in a power supply conductor accommodation groove 61 provided in the instrument base 60. The wire insertion confirmation member 63 connected by 63b is slidably fitted, and a confirmation window hole 65 is formed in the lid 64 to visually check whether the electric wire is securely inserted and locked in the power supply conductor 62. A joint box configured to be confirmed is known.

また、図１２に示すように電線導体が完全に挿入された時点で、蓋体７０に設けた表示孔７１から突出した確認棒７２が蓋体７０内に嵌入するように構成されたジョイントボックスが知られている。
特開２００３−３０８９２９号公報 Also, as shown in FIG. 12, there is a joint box configured such that the confirmation rod 72 protruding from the display hole 71 provided in the lid 70 is fitted into the lid 70 when the electric wire conductor is completely inserted. Are known.
JP 2003-308929 A

しかしながら、図１１に示す従来のジョイントボックスにおいては、一対の電線挿入確認駒６３ａ、６３ａ間をコイルスプリング６３ｂで連結した電線挿入確認部材６３を電源導体６２内に収納する際、コイルスプリング６３ｂを押し縮めて収納しなければならないため、コイルスプリング６３ｂに撓みが生じ電源導体６２内への装着が面倒なばかりでなく、コイルスプリング６３ｂの反発バネ力により電線挿入確認部材６３が電源導体６２から飛び出したり、電線挿入確認駒６３ａが飛ばされる等、作業性が極めて悪いという問題点があった。  However, in the conventional joint box shown in FIG. 11, when the electric wire insertion confirmation member 63 in which the pair of electric wire insertion confirmation pieces 63a and 63a are connected by the coil spring 63b is housed in the power supply conductor 62, the coil spring 63b is pushed. Since the coil spring 63b has to be retracted and stored, the coil spring 63b is bent and not easily installed in the power supply conductor 62, and the wire insertion confirmation member 63 jumps out of the power supply conductor 62 due to the repulsive spring force of the coil spring 63b. There is a problem that workability is extremely poor, such as the wire insertion confirmation piece 63a being skipped.

また、図１２（特開２００３−３０８９２９号公報参照）に示すジョイントボックスにおいては、蓋体７０から外方に確認棒７２が突出しているために機械的外力等により確認棒７２が損傷し役目をなさない等の問題点があった。  Further, in the joint box shown in FIG. 12 (see Japanese Patent Application Laid-Open No. 2003-308929), since the confirmation rod 72 protrudes outward from the lid 70, the confirmation rod 72 is damaged due to mechanical external force or the like. There were problems such as not doing.

本発明は従来の問題点を解決するためになされたもので、製造が容易で、且つ、電線の差込状態及び誤配線が目視により極めて容易に確認し得るジョイントボックスを提供することを目的とする。  The present invention has been made to solve the conventional problems, and it is an object of the present invention to provide a joint box that is easy to manufacture and in which the inserted state of a wire and erroneous wiring can be confirmed very easily by visual observation. To do.

最後に、図１に示すように器台１に、透明樹脂からなる解錠釦４０を嵌装した蓋体２０を螺子止め或いは加締付け固定する。  Finally, as shown in FIG. 1, the lid body 20 fitted with the unlocking button 40 made of transparent resin is screwed or fastened to the table 1.

図８はバネ部材１０と確認部材１５の動作説明図で、電線導体Ｃの先端部が確認部材１５の底板１５ａに当接すると確認部材１５がバネ部材１０に設けたバネ片１１ｃの反発バネ力に抗して回動し、電線導体Ｃが確実に挿入鎖錠された時点で確認部材１５に設けた表示部１５ｂが、蓋体２０に穿設した確認窓孔２２に位置するので、電線導体Ｃが確実に挿入鎖錠されたことが目視により極めて簡単に確認することができる。また、電線導体Ｃが引き抜かれた際には、確認部材１５はバネ部材１０に設けたバネ片１１ｃの反発バネ力により元の状態に復帰する。  FIG. 8 is an explanatory view of the operation of the spring member 10 and the confirmation member 15. When the tip end portion of the wire conductor C abuts against the bottom plate 15 a of the confirmation member 15, the repulsive spring force of the spring piece 11 c provided on the spring member 10 is confirmed by the confirmation member 15. Since the display portion 15b provided in the confirmation member 15 is positioned in the confirmation window hole 22 formed in the lid body 20 when the wire conductor C is securely inserted and locked, the wire conductor C is rotated. It can be very easily confirmed by visual observation that C is securely inserted and locked. When the wire conductor C is pulled out, the confirmation member 15 returns to the original state by the repulsive spring force of the spring piece 11c provided on the spring member 10.

上述のように、本発明によれば組み立て作業が容易で、電線導体の挿入鎖錠状態が目視により確認し得るばかりでなく、本発明に接続される電線が配線ダクト内に収納されている場合であっても電線被覆の色識別が目視により確認し得ることから誤配線を確実に防止し得る。  As described above, according to the present invention, the assembly work is easy and not only the insertion lock state of the electric wire conductor can be visually confirmed, but also the electric wire connected to the present invention is housed in the wiring duct. Even so, since the color identification of the wire coating can be confirmed by visual observation, erroneous wiring can be reliably prevented.
