AI Technical Summary
The existing magnetic switches are fixedly connected to the starter through only a set of screws. The tightness is relatively average and the screws are easily loosened and fall off due to bumps and jitters of the car, resulting in poor contact between the magnetic switches and unavailable to use them normally.
A car magnetic switch is designed, which uses two fixed structures: the first is formed by connecting the screw hole A of the screw A and the shell; the second is a conflict between the lock ring A and the lock ring B and the lock plate E, combined with screws, combined with screws The fixed connection between B and lock board B and lockboard D enhances the connection tightness between the magnetic switch and the starter.
By setting up two fixed structures, the connection tightness between the magnetic switch and the starter is significantly enhanced to avoid the problem of loosening the screw and falling off, and ensure the normal use of the magnetic switch.

Description
Technical Field
[0001] The utility model relates to the technical field of magnetic switches, in particular to an automobile magnetic switch. Background Art
[0002] The magnetic switch is one of the starter components.
