Perhaps, compression deformation portion 28 in also can omitting, but make the front surface of fore-end (for example cap 8) of cap 8 directly push against in second step 26.
Install in the housing 2 or after on the housing 2, just finished the assembling of electromagnetic switch shown in Figure 2 at other element with electromagnetic switch.
Shown in Figure 2ly schematically show out in Figure 10 according to the application's this electromagnetic switch and the key structure difference between the electromagnetic switch of the prior art shown in Figure 1.
Particularly, right half part shows among Figure 10 is the schematic structure at rearward end place of the housing 2 of electromagnetic switch of the prior art shown in Figure 1, wherein, cap 8, dish spring 21, electromagnetic core 4 are clamped between the step 22 and rear end flange 24 of housing 2 with certain axially preload force, dish spring 21 by axial compression fully between cap 8 and electromagnetic core 4 and do not have the ability of further axial deformation, also just without any the axial vibration damping ability.When electromagnetic core 4 was subjected to the axial impact of armature 16, impact was directly delivered to rear end flange 24 by dish spring 21 and cap 8, and this causes rear end flange 24 bigger axial deformation or play to occur.
Different therewith, left-half shows among Figure 10 is the schematic structure at rearward end place of housing 2 of the application's shown in Figure 2 electromagnetic switch, wherein, the front end periphery of cap 8 (for example locating flange 8b) is fixed on second step 26(or interior compression deformation portion 28) and rear end flange 24 between.Wavy spring 30 and electromagnetic core 4 are clamped in certain axially preload force between the step 22 of the front end face of cap 8 and housing 2.Wavy spring 30 not by complete axial compression between electromagnetic core 4 and cap 8, thereby have further axial elasticity deformation ability, this elastic deformability makes wavy spring 30 have the axial vibration damping ability.When electromagnetic core 4 is subjected to the axial impact of armature 16, the axial elasticity distortion of impact by wavy spring 30 is attenuated or absorbs, the impact that has so reduced is delivered to rear end flange 24 by electromagnetic core 4, and this makes the axial deformation of rear end flange 24 or play reduce.
Be appreciated that wavy spring 30 can be replaced by the flexible member of other form, for example dish spring, helical spring, cluster spring, rubber parts etc.
Figure 11 is the curve chart that compares electromagnetic switch cap play situation in the vehicle ignition process of prior art and the application by simulation.Wherein, abscissa is represented the vehicle ignition switch connection by the time of going through, and ordinate is represented the axial endplay of cap.Curve A is represented the cap play situation of electromagnetic switch of the prior art shown in Figure 1, and curve B is represented the cap play situation of the application's shown in Figure 2 electromagnetic switch.Can see that when armature bump electromagnetic core, according to prior art, tangible axial endplay (peak C) appears in the cap of the electromagnetic switch of prior art, and according to the application, tangible axial endplay does not appear in cap.
Figure 12 is electromagnetic switch (curve B) the transmission current situation between the binding post in the vehicle ignition process that compares prior art shown in Figure 1 (curve A) and the application by experiment.
Experiment showed, that after vehicle ignition switch is connected in the electromagnetic switch of prior art shown in Figure 1, electric current transmitted can experience be fallen (seeing the zone shown in the square frame D among Figure 12) suddenly between the binding post in uphill process, corresponding to the obvious axial endplay of cap.Different therewith, and electric current transmitted is not fallen in uphill process suddenly between the binding post of the application's electromagnetic switch.
According to prior art, when armature bump electromagnetic core, the obvious axial endplay that cap occurs may cause breaking away between contact bridge and the binding post, thereby the main circuit that causes motor takes place by opening circuit of moment.Electric current moment that this moment opens circuit in the main circuit that can cause motor falls suddenly, thereby may influence the operation of motor.Simultaneously, between contact bridge and binding post, can produce electric arc, thereby causing to produce between contact bridge and the binding post ablates and adhesion.
On the contrary, according to the application, when armature bump electromagnetic core, the obvious axial endplay that cap can not occur it is hereby ensured between contact bridge and the binding post can not break away from, thereby the main circuit that can not cause motor takes place by opening circuit of moment.Therefore, in the prior art in the motor main circuit electric current moment fall suddenly and contact bridge and binding post between ablate and the problem of adhesion is all avoided.
The application's other side relates to the electromagnetic switch with aforementioned structure and the vehicle starter that comprises this electromagnetic switch.
