After contact bridge 14 initially touched two binding posts 10, contact bridge 14 was prevented from and can not continues to move backward, and push rod 30 then continuation moves backward.At this moment, the compression stress of compression in the spring 22 begins to increase, so that the contact pressure between contact bridge 14 and two binding posts 10 increases gradually.After contact bridge 14 initially touches first distance (for example 0.05 to 0.1mm) that push rod 30 after two binding posts 10 continues to have moved backward a section very little; Set up initial status of electrically connecting between contact bridge 14 and two binding posts 10, the compression stress added value (being that current compression stress deducts pre-compression force) that compress in the spring 22 this moment is very little.
This initial status of electrically connecting can detect through checkout gear, thereby checkout gear obtains the initial turn-on signal.For example, begin to have electric current two binding posts 10 of flowing through, obtain the initial current signal of two binding posts 10 of flowing through by current sensor.
After the initial turn-on signal is detected, make push rod 30 further move second distance backward, this second distance is greater than first distance.For example, second distance is 0.5 to 1.5mm, preferably approximately 1mm.This second distance can be regarded as the reservation stroke, in order to guarantee contact bridge 14 with still can realize reliable the electrical connection after ablating in the contact site between two binding posts 10.
At this moment, electromagnetic switch is in position shown in Figure 4, and wherein, fastener 42 left a segment distance L (equal first distance and add second distance) in 14 minutes with contact bridge, and this distance is the displacement backward that contact bridge 14 and two binding posts 10 initially contact rear push-rod 30.
In this state, moving core 16 along the backward directions pushing, is pushed against in fixed iron core 4 until it, thereby be prevented from and further move backward.For example, the rear end face of moving core 16 pushes against on the substantial cylindrical path front end face partly of fixed iron core 4 at this moment.
Keep being in the said place of displacement backward and moving core 16 is pushed against under the state on the fixed iron core 4 at push rod 30, push rod 30 is fixed in the moving core 16.The two fixedly be through instruments such as crimping, riveted joint, welding with the 16b of fixed connection portion of moving core 16 through modes such as crimping, riveted joint, welding fixedly the periphery of push rod 30 (big footpath leading portion 30a) realize.The instruments such as crimping, riveted joint, welding that exist for of flange 16a provide bigger operating space.
In order to improve the bonding strength between push rod 30 and the moving core 16, carry out preliminary treatment on the position that can be crimped in the expection of push rod 30 or rivet, for example form roughened surface or depression, projection etc.
After push rod 30 and moving core 16 are fixed together, keeping moving core 16 to push against under the state of fixed iron core 4, in the homalocephalus portion 40 of push rod 30, process engagement windows 40a, in order to the upper end of shift fork is inserted wherein.Engagement windows 40a can form through methods such as punching press, laser processings.When processing engagement windows 40a, one or more position on the housing 2 (for example surface) can be used as positioning reference.
After processing engagement windows 40a, unclamp moving core 16, so that it is being with push rod 30 move forward (among Fig. 4 left) under compression spring 22 and 24 thrust.Push rod 30 move forward passed through afore-mentioned distance L after, fastener 42 touches contact bridge 14 and it is pulled away from two binding posts 10.Next, under the effect of compression spring 24, moving core 16 is being with push rod 30 to continue to move forward, and pushes against in the rear end of fixed iron core 4 until the anterior lip 28a of mount pad 28, for example pushes against in the groove of the rear end of fixed iron core 4.In this state, moving core 16 is being with push rod 30 to be prevented from and can not be further being moved forward.
Structure and manufacture process according to the above-mentioned electromagnetic switch of the utility model; Keep stroke and be and be detected the back at contact bridge 14 and initial status of electrically connecting between two binding posts 10 and establish through push rod 30 is further mobile backward; Therefore keep the influence that stroke does not receive Complex Dimensional Chain Analyses, thereby the tolerance that keeps stroke can be very little.
In addition, single push rod 30 is used, to replace two push rods of the prior art.In this structure, initially contact rear push-rod 30 at contact bridge 14 and two binding posts 10 and further moved a segment distance backward and kept moving core 16 to be pushed against under the state of fixed iron core 4 push rod 30 and moving core 16 are fixed together and form engagement windows 40a.Therefore, have simple dimension chain (the single push rod 30 of contact bridge 14-) between engagement windows 40a and the binding post 10, so the margin of tolerance of the size of engagement windows and location is also very little.In other words, size and alignment tolerance that engagement windows only exists finish to form, and the middle build-up tolerance that influences engagement windows size and alignment tolerance scope in the prior art is avoided.The size of the engagement windows of the utility model and the tolerance of location are much smaller than prior art, and the positioning accuracy of driven wheel can greatly improve.
Can see that the utility model improves the structure and the manufacture of electromagnetic switch with single-piece push rod, to reduce to keep tolerance and the size of engagement windows and the tolerance of location of stroke.The structure and the layout of other element relevant with the single-piece push rod, for example, the arrangement of the structure of sleeve 20, mount pad 28, fastener 42, compression spring 22,24 etc., the above-mentioned thought to the utility model does not constitute restriction.
For example, shown among Fig. 6 that the difference of electromagnetic switch is that mainly sleeve 20 has the diameter of increasing shown in itself and Fig. 2-4 according to the electromagnetic switch in the vehicle starter of another preferred implementation of the utility model.In this case, the diameter of the guide through hole of fixed iron core 4 correspondingly increases.The result; Space between the outer peripheral face of the path back segment 30b of the internal perisporium of the guide through hole of fixed iron core 4 and push rod 30 increases; So that the magnetic gap between fixed iron core 4 and the push rod 30 strengthens; Thereby the influence of the magnetic circuit that 30 pairs of solenoids of push rod 6 produce reduces, and this makes the magnetic material (for example ordinary steel) that utilizes low price process push rod 30 becomes possibility.In contrast, the push rod in the electromagnetic switch shown in Fig. 2-4 30 is processed by the nonmagnetic substance (for example copper, copper alloy, stainless steel etc.) of high price usually.
The others of the utility model relate to electromagnetic switch of processing through above-mentioned manufacturing approach with aforementioned structure and the vehicle starter that comprises this electromagnetic switch.
