Why does the Baojun 560's locking horn not sound?
1 Answers
The reasons why the Baojun 560's locking horn does not sound: 1. Contact erosion: If the horn is pressed for a long time, it can easily cause the horn contacts to erode and generate impedance. This weakens the current passing through the electromagnetic coil, reducing the electromagnetic attraction force, which fails to attract the armature to drive the diaphragm for normal vibration, resulting in a hoarse sound or even no sound at all. However, when the horn is pressed continuously, if a strong instantaneous current passes through the impedance, it can still work normally, leading to intermittent functionality. 2. Poor sealing leading to moisture: Although the interior of the horn is sealed, if the sealing is not tight, moisture can enter during car washing or water vapor can be present in the internal space. This moisture can easily cause the contacts to become damp and fail to function properly. 3. Poor contact at the electromagnetic coil terminals: Some horns have internal electromagnetic coil enameled wire terminal connections made of aluminum metal rivets pressed together rather than securely welded. If the insulation paint on the enameled wire ends is not properly removed or the rivet connections are not tight, it can easily lead to poor contact faults, resulting in malfunctioning of the horn.
