Description

Cable for irradiation-free heat-resistant starting device for automobile

Technical Field

The invention belongs to the technical field of cables, and particularly relates to a heat-resistant cable for an automobile cabin.

Background

The automobile starting device part, namely the engine cabin position, has high temperature during working, and has a lot of corrosive oil, the common cable insulating layer is difficult to meet the use requirement, and the cable used in the part mostly adopts radiation cross-linked polyolefin material as the insulating layer. However, the higher the temperature resistance requirement of the material is, the more complex the production process is, the higher the cost of the cable manufactured by using the material is, and the material is not suitable for wide application.

Disclosure of Invention

In order to solve the problem that the cost of a cable using an irradiation cross-linked polyolefin material as an insulating layer is high, the invention provides a cable for an irradiation-free heat-resistant starting device for an automobile.

The technical scheme adopted by the invention for solving the technical problems is as follows: the cable for the irradiation-free heat-resistant starting device for the automobile comprises a copper core, wherein a high-temperature vulcanized silicone rubber layer is arranged outside the copper core, a polytetrafluoroethylene film is arranged outside the high-temperature vulcanized silicone rubber layer, a phenolic fiber layer is arranged outside the polytetrafluoroethylene film, an oil absorption fiber felt layer is arranged outside the phenolic fiber layer, a copper wire woven layer is arranged outside the oil absorption fiber felt layer, and a fluorine rubber layer is arranged outside the copper wire woven layer.

Adopt the mature and relatively simple high temperature vulcanized silicone rubber of manufacturing process as the insulating layer, still can guarantee fabulous structural stability and insulating nature under 200 degrees centigrade, the reliability of insulating layer has been guaranteed, the production cost is reduced, polytetrafluoroethylene film is high temperature resistant and corrosion-resistant, fabulous oil-proof liquid infiltration effect has, the phenolic fiber layer has fabulous fire resistance, and with low costs, the oil absorption fiber felt layer has the effect of absorption infiltration oil, the copper wire weaving layer further improves cable bulk strength, the wear-resisting high temperature resistance of fluororubber sheath is fabulous sheath material.

The invention has the beneficial effects that: through scientific combination of various materials, the cable with excellent stability at high temperature and under oil liquid and lower cost is obtained.

Drawings

The invention is further illustrated by the following figures and examples.

Fig. 1 is a schematic structural view of the present invention.

In the figure: 1. the oil absorption fiber composite material comprises a copper core, 2 parts of a high-temperature vulcanized silicone rubber layer, 3 parts of a polytetrafluoroethylene film, 4 parts of a phenolic fiber layer, 5 parts of an oil absorption fiber felt layer, 6 parts of a copper wire woven layer and 7 parts of a fluororubber layer.

Detailed Description

In fig. 1, a cable for a radiation-free heat-resistant starter for an automobile, wherein: 1. the oil absorption fiber composite material comprises a copper core, 2 parts of a high-temperature vulcanized silicone rubber layer, 3 parts of a polytetrafluoroethylene film, 4 parts of a phenolic fiber layer, 5 parts of an oil absorption fiber felt layer, 6 parts of a copper wire woven layer and 7 parts of a fluororubber layer. The oil absorption fiber felt is characterized in that a high-temperature vulcanized silicone rubber layer is arranged outside the copper core, a polytetrafluoroethylene film is arranged outside the high-temperature vulcanized silicone rubber layer, a phenolic fiber layer is arranged outside the polytetrafluoroethylene film, an oil absorption fiber felt layer is arranged outside the phenolic fiber layer, a copper wire woven layer is arranged outside the oil absorption fiber felt layer, and a fluororubber layer is arranged outside the copper wire woven layer.
