Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Such as Fig. 1-3, the car electromagnetic switch of the utility model, including shell 1, the bobbin being set in shell 12 and
The enameled wire 21 being wound on bobbin 2.
Bobbin 2 is detachably set in shell 1, and stage casing is tubular structure, is inside installed with static iron core 3 and pull rod closes
Part.Pull rod component includes dynamic iron core 4 and pull rod 5, and dynamic iron core 4 is hollow structure 41 inside one end far from static iron core 3 to mitigate
Pull rod component weight, and then the impact force in electromagnetism work is reduced, have the function that vibration and noise reducing.The opposite side of dynamic iron core 4 is in
Frustum cone structure 42 along close to 3 direction of static iron core gradually extends to form, is inside provided in the axial direction with slot 43 from the coarse to fine.Wherein,
The internal diameter of hollow structure 41 is more than the internal diameter of slot 43.5 one end of pull rod is arranged in slot 43, and the other end is pierced by static iron core successively
3 and shell 1.Pull rod 5, which is penetrated on the body of rod of static iron core 3, is arranged with spring 6, and 6 one end of spring connection dynamic iron core 4, the other end abuts
Static iron core 3.
Static iron core 3 is axial in the middle part of a side end face of dynamic iron core 4 to offer one section of cone tank 31, along 31 end of cone tank
The first cylindrical groove 32, the second cylindrical groove 33 and third cylindrical groove are axially offered, wherein third cylindrical groove internal diameter is more than the first column
The internal diameter of shape slot 32, the internal diameter of the first cylindrical groove 32 are more than the internal diameter of the second cylindrical groove 33.Bushing is embedded in third cylindrical groove
35, bushing 35 is sheathed on pull rod 5
Spring 6 can be class Pagoda-shaped spring, and tail end doubling-up, one section of connection dynamic iron core 4 is the first cylindrical segment 61, intermediate
For conical section 62, abut static iron core 3 another section is the second cylindrical segment 63, and the diameter of conical section 62 is cylindrical from first
63 head end of section 61 ends to the second cylindrical segment becomes larger.61 outer sheath of the first cylindrical segment of spring 6 is equipped with damped ring 7,
6 inner ring of spring coordinates with pull rod 5, and outer ring and 7 location fit of damped ring, the second cylindrical segment 63 of spring 6 are located at the first column
It in shape slot 32, and holds out against in the slot bottom of the first cylindrical groove 32, outer ring and 3 inner wall location fit of static iron core so that 6 both ends of spring are equal
