PVC electronic connection line

Abstract

The invention relates to the field of wires and cables, in particular to a PVC electronic connection line. A layer of fire-resistant mica tape is arranged between a conductor and an insulated layer, the outside of the insulated layer is provided with an outer insulated layer, and a fire-resistant oxygen separation layer is arranged between the insulated layer and the outer insulated layer. The PVC electronic connection line has the advantages that the fire-resistant mica tape is arranged between the conductor and the insulated layer, the fire-resistant mica tape is a high-performance mica insulated product and has good high-temperature-resistant performance and combustion-resistance performance, and the single-face synthesis fire-resistant mica tape has good softness and cannot volatilize harmful smoke when combusting in an open fire; the fire-resistant oxygen separation layer is arranged between the insulated layer and the outer insulated layer, and a PVC protection sleeve can be effectively prevented from generating acid gas during combustion; the fire-resistant mica tape and the fire-resistant oxygen separation layer are arranged in the PVC electronic connection line, the fire-resistant effect is good, water-resistant gauze is arranged, and accordingly the PVC electronic connection line is resistant to water and fire.

Description

technical field [0001] The invention relates to the field of electric wires and cables, in particular to a PVC electronic connecting wire. Background technique [0002] Electronic connecting wire is an abbreviation for the internal wire of electrical equipment. It is used for connecting wires inside general electronic and electrical equipment. At present, the PVC electronic connecting wires on the market generally do not exceed 70°C, the rated temperature is 105°C, and the rated voltage is 300V. It has the advantages of anti-aging, easy to open, peeling, acid and alkali resistance, oil resistance and moisture resistance. However, it has high hardness, is not easy to bend, and is inconvenient to use, and in the actual use process, there are no safety protection measures when the ambient temperature is too high. [0003] An electronic wire disclosed in Chinese Patent Application No. 201220243110.7 includes a conductor and an outer insulating layer covering the conductor. The ...

At present, the PVC electronic connecting wires on the market generally do not exceed 70°C, the rated temperature is 105°C, and the rated voltage is 300V. It has the advantages of anti-aging, easy to open, peeling, acid and alkali resistance, oil resistance and moisture resistance. However, it has high hardness, is not easy to bend, and is inconvenient to use, and in the actual use process, there is no safety protection measure when the ambient temperature is too high

[0003] An electronic wire disclosed in Chinese Patent Application No. 201220243110.7 includes a conductor and an outer insulating layer covering the conductor. The insulating layer is provided with a thermochromic layer. By setting the thermochromic layer, the temperature of the electronic wire is observed. , when the temperature rises to a certain value, the electronic wire changes color, which is convenient for the staff to observe, and a flame retardant layer is set between the conductor and the insulating layer, resulting in small adhesion between the layers of the electronic wire, which affects the use efficiency and other problems

Moreover, the operator can ensure the safety during use by observing the color change of the color-changing layer, which is prone to mistakes and also has potential safety hazards
