Embodiment 1

[0044] Embodiment 1. In this embodiment, a three-core power cord of a household appliance is taken as an example.

[0045] The rated temperature of the three-core power cord of general household appliances is 60°C. The temperature-sensitive color-changing cable of the present invention is used as the three-core power cord. The color of the coating layer of the three-core power cord is black in normal use (not overloaded). ; When the running time is too long, the load increases or the external temperature increases, causing the temperature of the three-core power cord itself to exceed its rated temperature of 60 ° C, the color of the three-core power cord coating changes from black to red.

Embodiment 2

[0046] Embodiment 2, this embodiment takes a home cable as an example.

[0047] Because most of the general home cables are exposed outdoors, they are greatly affected by the ambient temperature; at the same time, with the passage of time, their coatings will age due to the influence of the external environment (UV, high temperature, rain, etc.) phenomenon, its safety effect will be reduced. Using the temperature-sensitive color-changing cable of the present invention as the home cable, when the load exceeds the withstand temperature of the cable, the color of the coating layer changes from black or other colors to red or other colors, which plays an intuitive role in advance. The warning function enables users to know the status of the current cable in advance.

Embodiment 3

[0048] Embodiment 3, this embodiment takes a motor lead wire (power wire) as an example.

[0049] In the field of industrial applications, high-power heavy electrical equipment such as motors and compressors are used most frequently, and there are factors such as high power, high calorific value, and large current required. Since motors generally run 24 hours a day and night, adding The environment used on the machine is unknown, so the motor is the most prone to overload and even burn out among all heavy electrical equipment. When the temperature-sensitive color-changing cable of the present invention is used as the motor lead-out wire (power wire), it can increase the current of the motor before overloading, and the calorific value is prominent, and the appearance color of the coating layer can be changed in advance, which is beneficial to the user. Serve as a warning.

Abstract

The invention provides a temperature-sensing color-changing cable, comprising at least one metal lead wire and a covering layer which covers the outer layer of the metal lead wire, wherein the covering layer comprises a base material and temperature-sensing color-changing powder; the temperature-sensing color-changing powder takes the base material as a substrate; and the color of the covering layer is changed along the change of the temperature. The temperature-sensing color-changing cable has the advantages that: the workability of the cable is strong; the cable has the direct and visual temperature-sensing color-changing effect, so that the potential safety hazard is visualized; the temperature state of the cable can be easily and directly detected without any thermoelectric couple, therefore, the potential safety hazard is visualized, and a terminal user can use the cable more safely.

Description

technical field [0001] The invention relates to the technical field of cable safety, in particular to a thermochromic cable. Background technique [0002] Cables are used in electronics, home appliances, heavy electricity and construction industries. Traditional cables are only about how to ensure the safety of customers in use. Generally, it is impossible to visually identify the current operating load of cables from the appearance. Therefore, in the use It is unable to provide user early warning function, only normal use and burnt two forms exist. There is one of the most important safety current values ​​in cable safety. The temperature of the wire itself will be different due to the heat generated by the cable load operation. When the electrical appliance exceeds the safe current overload and the temperature rises, it is impossible to remind the user by changing the color of the wire itself. The safety of this wire and whether it is suitable for this occasion can only b...
