【考案の詳細な説明】
この考案は、電気機器の動作表示装置の改良に関するも
のである。[Detailed Description of the Invention] This invention relates to an improvement of an operation display device for electrical equipment.
従来、近接スイッチ、光電スイッチ、リレー等の電気機
器の動作表示としては、ケースの表面に発光ダイオード
、ランプ等の発光素子を取付は内部の電子回路やリレー
が動作することにより発光素子を点滅させて動作確認を
行なっていた。Conventionally, to indicate the operation of electrical equipment such as proximity switches, photoelectric switches, and relays, light-emitting elements such as light-emitting diodes and lamps were attached to the surface of the case, and the light-emitting elements blinked when the internal electronic circuits and relays operated. I was checking the operation.
ところが、上記のようにケースの表面に直接発光素子を
取付付けた場合取付状態によって発光素子が壁等でかく
れたり、人間の見る方向によっては見えない状態が発生
する。However, when the light emitting element is attached directly to the surface of the case as described above, the light emitting element may be hidden by a wall or the like depending on the mounting condition, or may not be visible depending on the viewing direction of the person.
したがってケースの多方向に動作表示ができると大へん
都合がよいことになるが、発光素子をケースに複数個設
けるとなるとスペース、コスト、組立性等を考慮すると
大へんめんどうで実際には不可能であった。Therefore, it would be very convenient if the operation could be displayed in multiple directions on the case, but if multiple light-emitting elements were to be installed on the case, it would be extremely troublesome and impossible in practice, considering space, cost, ease of assembly, etc. Met.
さらに、ケースに発光素子が露出していると衝撃等で破
損することがあり寿命の点でも問題があった。Furthermore, if the light emitting element is exposed in the case, it may be damaged by impact or the like, which poses a problem in terms of service life.
この考案は、一つの発光素子で複数軸方向に動作表示が
可能で、しかも形状が大型化しないことを目的とする。The purpose of this invention is to make it possible to display motion in multiple axis directions with a single light emitting element, without increasing the size.
上記目的を遠戚するために、この考案は、電気機器本体
を内蔵した透明のケースの先端角部に凹部を形成し、こ
の凹部の内面に互いに分岐する少なくとも２個の導光路
を該ケースと一体に形成し、この導光路の分岐部に対向
させて発光素子を配設し、この発光素子の光を前記導光
路を通してケースから異方向へ導き出すようにしたこと
を特徴とする。In order to achieve the above object, this invention forms a recess at the tip corner of a transparent case that houses an electrical equipment main body, and at least two light guide paths that diverge from each other are formed on the inner surface of the recess. It is characterized in that it is integrally formed, a light emitting element is disposed opposite the branching part of the light guide, and light from the light emitting element is led out from the case through the light guide in different directions.
このような構成にすることによって、この考案は、一つ
の発光素子でケースの多方向へ動作表示が可能となり、
どの方向からでも動作確認ができ格別取付状態に配慮す
る必要がなく取付が容易で安価である。With this configuration, this invention enables operation display in multiple directions of the case with a single light emitting element.
The operation can be confirmed from any direction, there is no need to pay special attention to the installation condition, and installation is easy and inexpensive.
さらに、発光素子はケースの内部に収納するようにしで
あるのでケースの表面に露出することなく衝撃等で破損
することもない。Furthermore, since the light emitting element is housed inside the case, it is not exposed on the surface of the case and is not damaged by impact or the like.
また、導光路はケースの先端角部に凹部を形成すること
によってその内面に形成されるから、導光路がケースの
表面から突出することはなく、外形が大型化しないとと
もに、導光路がケースと一体に形成されるために、別部
材の導光路を必要とせず、安価に製作できるという効果
がある。In addition, since the light guide path is formed on the inner surface of the case by forming a recess at the tip corner, the light guide path does not protrude from the surface of the case, and the external size does not become large. Since it is integrally formed, there is no need for a separate light guide path and it can be manufactured at low cost.
以下、この考案の一実施例にもとづいて説明する。An embodiment of this invention will be described below.
第１図乃至第２図において、１０は透明なケース、１２
はケース１０の先端角部に設けた凹部、この凹部１２の
内面にはケース１０の外周肉厚部よりやや厚めの互いに
直角方向に分岐する導光路１３．１４を一体に形威し、
この導光路１３，１４の分岐部には一定の角度を有した
傾斜面１５゜１５が形威しである。In Figures 1 and 2, 10 is a transparent case, 12
is a recess provided at the tip corner of the case 10, and the inner surface of this recess 12 is integrally formed with light guide paths 13 and 14 that are slightly thicker than the outer peripheral wall thickness of the case 10 and branch in directions perpendicular to each other,
The branching portions of the light guide paths 13 and 14 feature inclined surfaces 15.degree. 15 having a certain angle.
１６は傾斜面１５．１５に対向するように配設した発光
素子、１７は発光素子１６を作動させる電気回路、１８
は外部ケーブル引出線である。16 is a light emitting element arranged to face the inclined surface 15.15; 17 is an electric circuit for operating the light emitting element 16; 18
is an external cable leader.
つぎに、作用を説明すると、発光素子１６が点灯すると
光は傾斜面１５．１５で屈折し、この先は導光路１３．
１４の壁に反射しながらケース１０の外面へ導かれ２方
向からの動作表示が可能となる。Next, to explain the operation, when the light emitting element 16 is turned on, the light is refracted at the inclined surface 15.15, and the light guide path 13.
The light is guided to the outer surface of the case 10 while being reflected on the wall 14, making it possible to display operations from two directions.
なお、導光路１３．１４の外端面１３ａ、１４ａを図示
のようにレンズ状に形成すれば光を効率的に集光でき光
量が増大する。Note that if the outer end surfaces 13a, 14a of the light guide paths 13, 14 are formed into lens shapes as shown, the light can be efficiently focused and the amount of light can be increased.
