In one embodiment, the temperature-sensitive color-changing layer is formed by mixing transparent silica gel or plastic and temperature-sensitive color-changing powder into a whole through injection molding.

In one embodiment, the noctilucent layer is formed by mixing silica gel or plastic and a light-storing noctilucent material into a whole through injection molding.

In one embodiment, the thermochromic layer is externally wrapped with a wear-resistant light transmitting layer.

In one embodiment, the abrasion resistant light transmitting layer is transparent PVC.

In one embodiment, the wear-resistant light transmitting layer is a woven mesh rubber.

In one embodiment, the insulating layer is a rubber wrapping.

In one embodiment, a plurality of touch accessories are arranged on the outer wall of the wear-resistant light-transmitting layer at intervals along the line body of the connecting line.

In one embodiment, the sticker is a magic tape or a double-sided tape.

To sum up, the utility model discloses for its beneficial effect of prior art is:

the utility model discloses simple structure, temperature sensing discoloration layer are transparent colourless state at normal temperature's initial condition, through set up temperature sensing discoloration layer on the connecting wire to make when taking place to transship, the connecting wire can heat up and cause temperature sensing discoloration layer to change colour, and the condition of user's accessible connecting wire outward appearance colour foresees in advance to carry out the outage of power and handles, avoids burning out of electrical apparatus. And under the state of no light at night, the position of the wire harness can be quickly identified through the luminous layer, and the luminous layer can display the brightness of the corresponding color through the color of the temperature-sensitive color-changing layer by combining with the temperature-sensitive color-changing layer under the condition that the temperature-sensitive color-changing layer is heated and changed, so that a user can know whether the electrical appliance connected with the wire harness is overloaded at night.

Detailed Description

The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:

as shown in fig. 1 to 2, an embodiment of the present invention preferably provides a safety harness, which includes a connecting line 1 and connectors 2 disposed at two ends of the connecting line 1, wherein the connecting line 1 includes a conductive layer 3, an insulating layer 4, a night light layer 8 and a temperature-sensitive color-changing layer 5, which are sequentially disposed from inside to outside, and the conductive layer 3 is electrically connected to the connectors 2. Specifically, temperature sensing discoloration layer 5 is transparent colourless state at the initial state of normal temperature, through set up temperature sensing discoloration layer 5 on connecting wire 1 to make when taking place to transship, the connecting wire can heat up and cause temperature sensing discoloration layer 5 to change colour, and the condition of user's accessible connecting wire 1 outward appearance colour foresees in advance to carry out the outage of power and handle, avoids burning out of electrical apparatus. And under the state of no light at night, the position of the wire harness can be rapidly identified through the luminous layer 8, and through combination with the temperature-sensitive color-changing layer 5, under the condition that the temperature-sensitive color-changing layer 5 is heated and changed in color, the luminous layer 8 can display the brightness of the corresponding color through the color of the temperature-sensitive color-changing layer 5, so that a user can know whether the electrical appliance connected with the wire harness is overloaded at night.

The temperature-sensing color-changing layer 5 is formed by mixing transparent silica gel or plastic and temperature-sensing color-changing powder into a whole through injection molding. The thermochromic layer 5 is in a transparent colorless state at an initial state at a normal temperature.

The luminous layer 8 is formed by mixing silica gel or plastic and a light-storing luminous material into a whole through injection molding. The light-storing luminous material can be used for storing energy in the temperature-sensitive color-changing layer 5 in a transparent and colorless state in the daytime.
