Description

[Technical field]

[0001] The utility model relates to a cable, in particular to a cable which can change color with temperature. [Background technology]

[0002] With the development of society, power cords are increasingly used in various fields. However, during use, the heat generated by the cable load operation will cause the temperature of the cable itself to be different. When the current flowing through the cable is too large, it is easy to heat up, and users cannot visually identify the current cable load from the appearance. Therefore, it cannot provide users with early warning during use, and they will only be discovered when it burns out or an accident occurs.

[0003] Therefore, it is necessary to provide a cable that can detect cable overload and heating in time and has low cost. [Contents of the utility model]

[0004] The main purpose of the utility model is to provide a cable, the color of which changes when the cable is heated.

[0005] To achieve the above-mentioned purpose, the utility model can adopt the following technical scheme: a cable, which includes a core wire, a shielding layer covering the core wire, an insulating protective layer covering the shielding layer, and an outer layer located outside the insulating protective layer, the outer layer including a color-changing yarn that can change color with temperature and a non-color-changing yarn woven together with the color-changing yarn.

[0006] Compared with the prior art, the utility model has the following beneficial effects: the outer layer of the cable of the utility model is woven by color-changing yarn and non-color-changing yarn, so that the appearance color of the cable can change due to changes in temperature, providing early warning of possible high-temperature failures during operation, making it easy for users to discover overload and heating phenomena of the cable, thereby improving the safety of cable use and lowering the cable cost.

[0015] Power inner conductor 110 Filling wire 60

[0016] Power insulation layer 111 [Specific implementation method]

[0017] See also Figure 1 As shown, a cable 100 in accordance with the present invention is shown. The cable 100 can be used to charge electronic devices such as mobile phones. The cable 100 includes a core wire 10, a shielding layer 20 covering the core wire 10, an insulating protective layer 30 covering the shielding layer 20, and an outer layer 40 located outside the insulating protective layer 30.

[0018] The core wire 10 includes a power core wire 11 and a signal core wire 12. The power core wire 11 includes a power inner conductor 110 and a power insulation layer 111 coated outside the power inner conductor 110. The material of the power insulation layer 111 is TPEE (Chinese full name: polyester rubber). The signal core wire 12 includes a pair. Each of the signal core wires 12 includes a signal inner conductor 120 and a signal insulation layer 121 coated outside the signal inner conductor 120. The material of the signal insulation layer 121 is HDPE (Chinese full name: high-density polyethylene resin). The diameter of the power core wire 11 is greater than the diameter of the signal core wire 12. The shielding layer 20 is wrapped around the outside of the core wire 10. The shielding layer 20 includes a first shielding layer 21 and a second shielding layer 22 coated outside the first shielding layer 21. The first shielding layer 21 is longitudinally coated outside the core wire 10, and the second shielding layer 22 is wrapped around the outside of the first shielding layer 21. The first shielding layer 21 includes a metal aluminum layer and a PET (Chinese full name: tetrafluoroethylene-hexachloropropylene copolymer) layer disposed on the metal aluminum layer. The insulating protective layer 30 is made of PVC (Chinese full name: polyvinyl chloride) material.

[0019] The cable 100 further includes a ground wire 50 and a filling wire 60 disposed between the core wires 10. Specifically, in this embodiment, two ground wires 50 and four filling wires 60 are included. The two ground wires 50 are separated by the power core wire 11. The diameter of the ground wire 50 is smaller than the diameter of the signal core wire 12.

[0020] The outer layer 40 is located at the outermost side of the cable 100. The outer layer 40 includes a color-changing yarn that can change color with temperature and a non-coloring yarn woven together with the color-changing yarn. The color-changing yarn is a mixture of polyester fiber and a temperature-sensitive color-changing material. The non-coloring yarn is made of polyester fiber. The color-changing yarn is only a thread of one color. Of course, the color-changing yarn can also include threads of multiple different colors. By using color-changing yarns of different materials, the basic temperature for the color change of the color-changing yarn is 31 degrees or 45 degrees, that is, the color-changing yarn begins to change color when the temperature exceeds 31 degrees or exceeds 45 degrees, and the higher the temperature, the darker the color. The color-changing yarn can change color repeatedly as the temperature rises and falls. The number of the color-changing yarn and the non-coloring yarn is the same. Of course, in other embodiments, the number of the color-changing yarn and the number of the non-coloring yarn may also be different. Since the price of color-changing yarn is higher than that of non-coloring yarn, the outer layer of the cable 100 of the utility model is composed of two colors of yarn, color-changing yarn and non-coloring yarn, which is less expensive than only color-changing yarn. The diameter size of the color-changing yarn and the non-coloring yarn is the same. The diameter size of the color-changing yarn can be between 0.08m and 0.1mm.

[0021] The new cable 100 can change color repeatedly with the rise and fall of temperature, and can change color due to the change of temperature. This intuitive and visual temperature-sensitive color-changing effect makes the potential safety hazard visible, and allows people to judge the working status of the cable according to the color status, which plays a role of early warning.
