Abstract
An antenna for auto radio, falling into field of auto sound parts, is composed of insulation skin multistrand copper core flexible wire and an enameled wire coil wound outside the insulation skin multistrand copper core flexible wire, wherein bare wire end of the insulation skin multistrand copper core flexible wire is connected with output of the radio antenna; two end wires of the enameled wire coil are connected with the audio and positive pole of auto power supply, respectively; and a thermoplastic sleeve is sleeved at outer surface of the enameled wire coil. The utility model has simple structure and low cost, prevents radiation and various interferences via shielding effect, generated by electromagnetic field formed after the enameled wire coil on the insulation skin multistrand copper core flexible wire is powered, improves auto radio reception sensitivity, and improves auto radio reception effect.
Description
Technical field
A kind of antenna that is used for auto radio of the utility model belongs to the automobile audio fitting field.
Background technology
Existing radio aerial of cars adopts a very long coaxial shielding line usually, adds a pull bar again.This coaxial shielding line is middle soft-hearted line of plastics suitcase multiply copper, and the outside is copper-clad ground connection again, and this type antenna is not only installed trouble, and cost is high, and easy scratching car surface.Existing luxury car does not have outside antenna yet, and its inside antenna amplifier costs an arm and a leg, technical sophistication, and cost is very high.
The utility model content
The purpose of the utility model provides a kind of antenna that is used for auto radio, to improve the radio reception sensitiveness of auto radio, promotes the radio reception effect of auto radio.
The utility model is used for radio aerial of cars; Form by insulated hull multiply copper core flexible cord and enameled wire loop; Outside insulated hull copper core flexible cord, be tied with enameled wire loop; The bare terminal end of this insulated hull copper core flexible cord is connected with radio antenna output, and enameled wire loop two ends line is connected with broadcast receiver, automobile power source positive pole respectively.
The above-mentioned antenna that is used for auto radio is with the thermoplastic sleeve pipe at its enameled wire loop outer surface.
The design is simple in structure, and cost is low, but through shielding action radiation proof and various interference that the electromagnetism place that forms after the conduction of the enameled wire loop on the insulated hull copper core flexible cord produces, improves the radio reception sensitiveness of auto radio, promotes the radio reception effect of auto radio.

Embodiment
How combine accompanying drawing to illustrate the utility model implements at present:
Example 1, certain automobile interior are used broadcast receiver
The insulated hull multiply copper core flexible cord 1 of this antenna, long 220mm, one of which end are bare terminal end L; Outside insulated hull multiply copper core flexible cord 1, twine the enameled wire loop 2 of 200mm, for the orderly standard of product; Be with thermoplastic sleeve pipe 3 at the enameled wire loop outer surface; The two ends of this enameled wire loop 2, its nearly copper core bare terminal end L is inner termination N, another termination is external end head W; The inner termination N of enameled wire loop, external end head W are connected with the positive pole of broadcast receiver, automobile power source respectively, and the naked end L of internal copper heart yearn is connected with radio antenna output.
The utility model antenna size and employed auto radio coupling are not limited to by the foregoing description.
Claims (2)
