Description
Technical Field
The invention belongs to the technical field of cables, and particularly relates to a cable for an automobile antenna.
Background
The automobile antenna is a device for intercepting high-frequency electric waves transmitted by a transmitting station and transmitting the high-frequency electric waves to a receiver of an automobile radio, an automobile telephone or radio navigation equipment so as to demodulate carrier waves.
The cable is the important component part of car antenna, based on its service environment, assembles a cable that has softness, resistant buckling, anti-interference characteristics, is the prerequisite of guaranteeing car antenna stable work.
Disclosure of Invention
In order to meet the requirements, the invention provides the cable for the automobile antenna, wherein the cable body of the cable for the automobile antenna is soft, tensile and durable, and the normal work of the automobile antenna is ensured.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a cable for automobile antenna, includes the sinle silk, the sinle silk is formed by a plurality of wires transposition, the structure of wire is: the innermost layer is a conductor which is formed by twisting a plurality of single crystal copper wires, a chlorinated polyethylene insulating layer is arranged outside the conductor, and conductive paint is arranged outside the chlorinated polyethylene insulating layer;
the oil absorption fiber felt is characterized in that a crosslinked polyvinyl chloride layer is arranged outside the cable core, water-blocking powder is filled between the cable core and the crosslinked polyvinyl chloride layer, a polyimide fiber layer is arranged outside the crosslinked polyvinyl chloride layer, a copper wire woven layer is arranged outside the polyimide fiber layer, a polyurethane fiber layer is arranged outside the copper wire woven layer, an oil absorption fiber felt is arranged outside the polyurethane fiber layer, and a chlorosulfonated polyethylene rubber layer is arranged outside the oil absorption fiber felt.
Preferably, the number of the wires is not less than 4.
Preferably, the conductive paint is conductive silver paint or nickel conductive paint.
Preferably, the thickness of the oil absorption fiber felt is not less than 0.5 mm.
The single crystal copper has excellent electrical and signal transmission properties, good plastic workability, excellent corrosion resistance, and remarkable fatigue resistance due to elimination of grain boundaries as a resistance generation source and a signal attenuation source, and the conductor is formed by twisting single crystal copper wires and has excellent flexibility; the chlorinated polyethylene has excellent weather resistance, ozone resistance, chemical resistance and aging resistance, and also has excellent toughness, and the good toughness can be still maintained even at the low temperature of minus 30 ℃; compared with the traditional metal shielding layer, the conductive paint provides electromagnetic shielding performance for the wire under the condition of hardly influencing the flexibility of the wire.
Cross-linked polyvinyl chloride has water-fast, acidproof, alkali-proof, the nonflammable, and ozone-resistant, heat-resisting, performances such as resistant time, can effectual protection sinle silk, the polyimide fiber layer not only plays thermal-insulated effect, still has electromagnetic shielding characteristic, the copper wire weaving layer is soft and intensity is high, a bulk strength for isolated outside electromagnetic signal and increase cable, polyurethane fiber layer soft strength is high, a burr for isolating on the copper wire weaving layer, prevent to cut the oversheath, chlorosulfonated polyethylene rubber has unique ageing-resistant, heat-resisting, fire-retardant, especially resistant time, performances such as resistant ozone and resistant chemical corrosion, be fabulous oversheath material.
The invention has the beneficial effects that: through structural design and material selection, under the condition that does not influence the cable compliance, be equipped with multilayer shielding layer, obtain a tensile, durable cable for car antenna.
