Description

  The present invention relates to a warning device for preventing ignition of an electric wire, and in particular, an electric wire that has a temperature-sensitive color changing function that warns a user when the electric wire of an electric product is overheated and that can be replaced when the temperature-sensitive color changing function is reduced. The present invention relates to a warning device that prevents the ignition of a fire.

  There is a close relationship between the use of electric power and the lives of modern people, and most of various electric products are connected to plugs of commercial power sources via electric wires, and supply electric power to electric products via electric wires. General electric wires have rated voltage and current capacity. When the voltage and current sent by the wires exceed the rated load, the core wire inside the wire generates heat and the insulation layer covering the outside of the core wire melts, causing the wire to ignite. There was a risk of losing life and property.

  However, general users have little knowledge about the electrical standards, and even if the load on the electric wire becomes too large or overheated, it is difficult to notice and the electric wire may ignite. The conventional technology of some manufacturers immerses or immerses temperature-sensitive discoloration ink in the insulation layer of the wire, and the core wire in the wire generates heat when the voltage and current flowing through the wire exceed the load. When the temperature changes abnormally, the color of the temperature-sensitive discoloration ink in the insulating layer changes to warn the user, and the user can visually recognize that the load or temperature of the electric wire has become too large. Therefore, it can prevent effectively that an electric wire ignites.

  However, as you can see in actual use, the method of immersing or immersing the temperature-sensitive color change ink in the insulation layer of the wire is expensive and the temperature-sensitive color change ink is used for a certain time (about 1.5 years). As time passes, the temperature-sensitive discoloration function is greatly diminished, and even if the load and temperature of the wires increase, the temperature-sensitive discoloration ink will not change color, and it can be known that the warning function has been lost. It was very inconvenient to replace the electric wire with a new one every time, and it was difficult to actually do it because of the maintenance cost.

  Therefore, the present inventor has studied based on many years of abundant design and development and actual manufacturing experience in the field in view of the conventional method of immersing or immersing temperature-sensitive discoloration ink in the wire insulation layer.・ Improved and created a more practical and valuable invention.

  An object of the present invention is to provide a warning device that prevents a wire from being ignited and has a temperature-sensitive color-changing function that warns a user when an electric wire of an electric product is overheated and that can be replaced when the temperature-sensitive color changing function is deteriorated. There is.

  According to a first aspect of the present invention for solving the above-described problem, an identification display layer is formed on one end surface of the foundation layer, and the identification display layer includes at least one identification pattern. A temperature-sensitive color-changing layer is coupled to an end surface of the base layer on which the identification display layer is formed, the temperature-sensitive color-changing layer including at least one temperature-sensitive color-changing portion, and Is covered with the temperature-sensitive discoloration part, and a warning device for preventing ignition of an electric wire is provided.

  The identification display layer includes a plurality of different identification patterns, the temperature-sensitive color-changing layer includes a plurality of temperature-sensitive color-changing portions having different color-changing temperatures, and the identification pattern is over the temperature-sensitive color-changing portion, respectively. It is preferable that the colors of the identification patterns are different from each other, and a display warning text is written beside the identification pattern of the identification display layer.

  It is preferable that the identification display layer includes a display date, and the display date includes at least one of a manufacturing date and an effective date.

  When actually using the warning device for preventing the ignition of the electric wire of the present invention, it is affixed to the electric wire or plug of an electric product, the voltage and current flowing through the electric wire exceed the rated load, or the electric wire overheats and a high temperature is generated. When the temperature reaches the temperature set in the temperature-sensitive color changing portion, the color of the temperature-sensitive color changing portion changes to transparent, and an identification pattern covered by the temperature sensitive color changing portion appears. For this reason, when the user knows that the electric wire of the electrical product is overheated visually, the electric wire can be dealt with so that it does not ignite, and when the temperature-sensitive discoloration part is altered and the temperature-sensitive discoloration function is reduced, The warning function can be easily maintained because it can be peeled off from the electric wire of the electric product and replaced with a new one.
