本発明は、±2面の面良導体に電流を負荷させ、ダイオード端子を任意の位置で差込み固定することによりダイオードランプが点滅する機能を備えた、
ダイオード端子の差込み固定式接続方法に関する。
The present invention is provided with a function that a diode lamp blinks by loading a current to a good conductor of ± 2 surfaces and inserting and fixing a diode terminal at an arbitrary position.
The present invention relates to a method of connecting and fixing diode terminals.

従来のダイオードの接続構成は、±リード線を良導体としダイオード端子と±リード線をハンダ等で接続させ点滅させる方法が一般的であった。    A conventional diode connection configuration is generally a method in which a ± lead wire is a good conductor and the diode terminal and the ± lead wire are connected with solder or the like to blink.

発明が解決しようとする課題Problems to be solved by the invention

従来のリード線連結方式では、ダイオード端子とリード線とはハンダ付けによるもので青色ダイオード等点灯色が多くなった現状では、配線が雑多となる問題点があった。    In the conventional lead wire coupling method, the diode terminals and the lead wires are soldered, and there are problems in that the wiring is miscellaneous in the present situation where the number of lighting colors such as blue diodes has increased.

本発明は、幾多のダイオード端子のハンダによる点接着を解消することを最大の目的としており、さらに、伝導パネル内部に密集して複数のダイオードが簡単に収納できる構成及び接続方法を提供することが目的である。    The present invention has the greatest object of eliminating point bonding due to soldering of a large number of diode terminals, and further provides a configuration and a connection method capable of easily storing a plurality of diodes densely inside a conductive panel. Is the purpose.

課題を解決するための手段Means for solving the problem

上記の目的を達成するために、本発明のダイオード端子の固定方法においては、±2組の面良導体を設け、更に、ダイオード端子の差込み固定板兼絶縁板に発発泡スチロール・スポンジゴム・積層綿等を面良導体の上下に挟む形で設ける。    In order to achieve the above object, in the diode terminal fixing method of the present invention, ± 2 sets of good surface conductors are provided, and further, foamed polystyrene, sponge rubber, laminated cotton, etc. are provided on the insertion fixing plate / insulator plate of the diode terminal. Are provided so as to be sandwiched between the top and bottom of the good conductor.

上記ダイオード端子の取り付ける位置は、標識板の標示に沿って字画・方向・数字等が明確に発光するよう差込み固定される。さらに、発光色の配列は計画して定める。本発明の特徴はダイオード端子を局部的に密集して差込み固定する事が可能である点である。    The position where the diode terminal is attached is inserted and fixed so that strokes, directions, numbers, and the like are clearly emitted along the markings on the sign board. Furthermore, the arrangement of emission colors is determined by planning. A feature of the present invention is that the diode terminals can be locally inserted and fixed.

上記ダイオードの±端子は、長端子と短端子が具備されており、長端子は±いずれか一方の面良導体を突き抜ける周囲を絶縁被覆され、さらに、先端を鋭利に尖らして他の一方の面良導体に突き差し固定される。短端子も、先端を鋭利に尖らし、±いずれか片方の面良導体を突き差し固定する。    The ± terminal of the diode has a long terminal and a short terminal, and the long terminal is covered with insulation around the one of the good conductors, and the other one of the good conductors is sharply pointed. It is fixed to the end. The short terminal is also sharpened at the tip, and either one of the good conductors is inserted and fixed.

上記±面良導体に具備する電極帯は、面良導体の一端に金属電極帯又は金属箔電極帯及び金属インク電極帯等が設けられる。又ダイオード発光を点滅させるために、±それぞれの面良導体に電極帯が設けられる。区分された電極帯には、それぞれ電源電流からのリード線が接続されており交互に電流を導通させ点滅させる。    The electrode band provided in the above-mentioned good surface conductor is provided with a metal electrode band, a metal foil electrode band, a metal ink electrode band or the like at one end of the surface good conductor. In addition, in order to blink the diode light emission, an electrode strip is provided on each good surface conductor.

上記面良導体は、針刺し固定が可能な発泡ウレタン又は発泡ゴムスポンジに低抵抗のカーボン塗料を含浸・乾燥したカーボン面良導体又は針刺し可能な基布に金属箔を付着した良導体が望ましい。    The above-mentioned good conductor is preferably a good conductor obtained by impregnating and drying a low-resistance carbon paint on a foamed urethane or foamed rubber sponge which can be fixed with a needle stick, or a good conductor having a metal foil attached to a base cloth capable of needle stick.

上記面良導体又は面絶縁板を順次組み立てた標識板は、冬季融雪又は凍結により遮断され不透明になるため、本発明は標識板の背面にカーボン面発熱体又は面状発熱体を設け、標識板周囲をガラス板又は樹脂板で覆い防水保温効果をもたらし、前記面発熱体を放射させることによりガラスの凍結を解凍させ鮮明にさせる。    The sign board in which the above-mentioned good conductors or the surface insulating plates are sequentially assembled is blocked by the snow melting or freezing in winter and becomes opaque.
