Description

Color signal line and method for manufacturing the same

Technical Field

The present invention relates to an electrical device and a method for manufacturing the same, and more particularly to a color signal line and a method for manufacturing the same.

Background

In the conventional manufacturing technology of signal lines (signal lines for transmitting signals or power lines for transmitting current), opaque plastic material is directly molded on the wires by extrusion molding. If the color of the signal line is to be changed, the plastic material must be added with a coloring material. The signal line manufactured by the traditional manufacturing technology has monotonous or irregular color change only by the added pigment, and cannot generate crystal color change.

Recently, some signal line manufacturers use transparent plastic material to directly form the conductive wires, and add color to the transparent plastic material to change the light transmission color of the signal lines. This method can make the manufactured signal line have more glittering and translucent color. However, the color of the transparent plastic material is monotonously changed by the different coloring materials added to the transparent plastic material, and thus, the color characteristics cannot be changed in a wide range.

Some signal line manufacturers attempt to wrap a colored tape around the circumference of the main body of the conductive wire by winding. However, the thickness of the color strip is too large, so that the color signal wire formed after the transparent plastic material is extruded and molded on the color strip on the circumferential surface of the wire body has too high hardness and is not easy to bend, and the outer diameter of the manufactured color signal wire is too large, so that the color signal wire does not meet the standard specification of the signal wire. However, if the colored ribbon body with a thinner thickness is wound on the circumferential surface of the lead body, the ribbon body is easily broken in the high-speed winding process due to the thinner thickness, and the mass production efficiency and the product quality are greatly reduced. In addition, the width of the color tape body cannot be controlled within a reasonable range, so that the color tape body is easily wrinkled when being wound on the circumferential surface of the wire body during the high-speed winding process, and further the color tape body cannot be uniformly wound on the wire body, thereby causing the uneven surface of the manufactured color signal wire. Moreover, since the overlapping width between adjacent colored tapes cannot be controlled within a reasonable range, when the manufactured colored signal line is bent, the colored tape is easy to separate from the covering surface, so that the lead body is exposed, and the integrity of the appearance color of the signal line is seriously damaged.
