Problems solved by technology

However, since the rod antenna is installed outside the vehicle, and the antenna support rod generally has a certain length, it is often affected by the environment during the daily driving of the motor vehicle, for example, strong winds, etc., will cause the antenna to The shaking of the support rod, and the shaking of the antenna support rod is bending deformation in all directions, which increases the mutual extrusion and wear between the terminal part 110 and the antenna element 120; seriously causes the winding between the antenna element 120 and the terminal part The antenna lead wire at the junction of 110 breaks, which makes the electrical conduction between the antenna element 120 and the terminal part 110 fail, and finally makes the rod antenna fail
Moreover, due to the limitation of the mechanical properties of the flat copper wire used as the antenna lead wire, it cannot resist the fatigue damage caused by extrusion wear between the antenna element 120 and the terminal portion 110

Description

technical field [0001] The present invention relates to a vehicle antenna used for mobile services, in particular to a vehicle antenna used to prevent an antenna element from breaking with a connecting part, thereby causing conduction failure. Background technique [0002] Motor vehicles are often provided with radio equipment that requires an antenna to receive radio signals, such as FM / AM radios, telephones, and the like. Although some antennas are built into the windshield or other parts of the vehicle, the most effective and least expensive antennas are rod antennas, which are usually mounted on the fender of the motor vehicle and are operatively connected to radio equipment to provide radio signals. [0003] In general, such as figure 1 As shown, the rod antenna installed on the fender of the motor vehicle includes a terminal part 110 fixed on the fender and an antenna element 120 connected to the terminal part 110 . The antenna element includes an antenna support ro...
