Embodiment
Fig. 1 shows the trigger mechanism 10 of the oil engine with starting relay 13 (also referred to as connecting rly.) with transverse sectional view. Such trigger mechanism 10 is mainly used in motor vehicle, and is called as starting engine, especially release formula spiral wheel trigger (Schub-Schraubtrieb-Starter). Motor 11 (especially starting engine), transmission rig 12 (especially sun and planet gear mechanism) and starting relay 13 (especially magnetic switch) belong to main assembly. Motor 11 is in the effective of machinery by means of armature shaft 14 and transmission rig 12 and is connected. Transmission rig 12 is by means of the separative element 15 adjacent with armature shaft 14, and especially covering plate or covering dish, be separated with motor 11. It is important in this that, armature shaft 14 is provided with sealing element, and sealing element forms the sealing portion of rotatable motion together with separative element 15. Sealing portion is arranged in the region surrounded by mark window 17. Thus, achieve a kind of decoration form by technical scheme here, this decoration form is protected transmission rig 12 not by the infringement of particle or medium penetrant.
In the starting process of oil engine, motor 11 temporarily is connected with oil engine by gear drive by magnetic switch. Due to the typical high rotating speed of electric motor 11 with for the moment of torsion needed for starting process, it is necessary to big transmitting ratio. Desired transmitting ratio is by the pinion(gear) (especially starting pinion(gear)) at trigger place and realizing relative to starting the bigger pinion(gear) of pinion(gear) by corresponding flywheel. Start pinion(gear) can axially infinitely move on armature shaft 14, and engaged with the portion of engagement of flywheel by magnetic switch or electromagnet. Afterwards, connecting motor or electric motor 11 followed by closed contact switch, contact switch is a part for magnetic switch or pushes away the part into magnet more precisely. Starting pinion(gear) and be equipped with freewheel, this freewheel prevents the oil engine started from too high rotating speed drive-motor 11 by the starting pinion(gear) still engaged and thus being damaged or destroying motor 11. Such starting engine generally has the electric motor of series motor or lasting excitation as motor 11.
Motor 11 is made up of immovable parts (stator) and the parts (rotor) that rotatably supported. In this case, it relates to inner rotor type motor, its rotor limits the part of the part of the inside of motor 11 and the outside of its stator restriction motor 11. Rotor has the coil with iron core, and it is also referred to as armature and can be rotated to support in the magnetic field between the pole boots of stator. In motor 11, replace so-called excitation winding by permanent magnet, i.e. permanent magnet. Due to the permanent magnet of advanced person, stator winding can be saved in for the trigger mechanism of motor vehicle. Coil, the especially armature winding of armature is manipulated by reverser. Such as, reverser realizes the connection of housing to armature winding by two fixing carbon brush (it is compressed against on the cylinder jointly rotated with armature). The surface of cylinder is divided into the section of mutually insulated. As general in direct-current machine, the winding quantity that armature has is the half of the section quantity of reverser. At this, each winding is connected with two sections relative to each other in its end. Due to the special requirement to moment of torsion and electric current, the cross section between section and the carbon brush of correspondence is especially wide. When four carbon brush, two windings can be simultaneously effective, and when six carbon brush, three windings can effectively simultaneously.
In the embodiment shown in this, contact switch comprises contact 16, and this contact is configured in case lid place in case side, or in brief, covers 18 places.

According to Fig. 2, except switch axle 21, contact device 20 comprises contact bridge shape contact pin 22 and make spring 23, and this make spring is axially pre-tight on switch axle 21 by contact bridge shape contact pin 22. Contact device 20 has and rotates stop portion 30a, and in shown diagram, this rotation stop portion 30a is integrally, that is corresponding to contact device 20 integratedly parts, i.e. switch axle 21 be configured in together. Rotation stop portion 30a is included in first in the first area of switch axle 21 and rotates asymmetric cross section 31, and switch axle is bearing in the corresponding guidance cavity 24a of magnetic core 24 (see Figure 16-18) in this region. Forming section 31a that radially stretched out from the cylindrical matrix 21a of switch axle 21 by two, square forms cross section 31, and forming section 31a is arranged on matrix 21a relatively.
Switch axle 21 stretches out from the guidance cavity 24a of magnetic core 24 and/or arranges the accommodation section of contact bridge shape contact pin 22 at the 2nd zone in the second area, in this second area, switch axle 21 has rotationally symmetrical cross section, rotatably holds contact bridge shape contact pin 22 with the cross-section rotationally symmetrical at this. In the 2nd region of switch axle 21, it is being configured between the stopper ring 25 of convex annular shoulder and the contact bridge shape contact pin 22 held to be furnished with the make spring 23 being configured to helical pressure spring. The contact bridge shape contact pin 22 of accommodation is pressed against on the axial retention region 27 being configured to stop plate 27a by it. 3rd region or axial retention region 27 are with for cross section that is that have non-rotating symmetry with holding the 2nd rotationally symmetrical area adjacency of contact bridge shape contact pin 22 or that rotate asymmetric rectangular in form. This cross-section corresponding is in the cross section of the through hole 22a of contact bridge shape contact pin 22, and this cross-sectional configuration becomes complementary with through hole 22a, is that is configured to rectangle equally. As long as through hole 22a and stop plate 27a is correspondingly directed at, contact bridge shape contact pin 22 just can axially move across stop plate 27a by this through hole 22a. If through hole 22a correspondingly rotates about 90 �� relative to stop plate 27a, as, shown in Fig. 2 to 4, make spring 23 makes the contact bridge shape contact pin 22 of accommodation abut against on stop plate 27a, thus contact bridge shape contact pin 22 is compressed against on stop plate 27a. Contact bridge shape contact pin 22 has the part 22b of the annular being positioned at central authorities, diametrically extends radially a contact element 22c from this part 22b respectively, and contact bridge shape contact pin 22 utilizes contact element 22c to contact corresponding contact 16. At this, two contact element 22c are preferably of similar shape, and are arranged to tilt relative to the part 22b of the annular being positioned at central authorities a little.

At this, first guiding make spring 23 is crossed stop plate 27a and is arranged between stopper ring 25 and stop plate 27a for (Fig. 6 and 7) in the 2nd region holding contact bridge shape contact pin 22. Afterwards, rotating contact bridge shape contact pin 22 so that the cross section of its through hole 22a or through hole 22a is directed at matchingly or complementally with the cross section of stop plate 27a. And then, make contact bridge shape contact pin 22 axially move across stop plate 27a, wherein, make spring 23 by the axial motion of contact bridge shape contact pin 22 by compression and be thus tightly resisted against on stopper ring 25 in advance. Once contact bridge shape contact pin 22 axially moves across stop plate 27a, with regard to rotating contact bridge shape contact pin 22 so that stop plate 27a can not be crossed again and axially move. At this, it is preferable that make contact bridge shape contact pin 22 rotate 90 ��. In order to simplify correct rotation, such as, supplementary card lock section or groove are set. In the position rotated, contact bridge shape contact pin 22 is pressed against on stop plate 27a by make spring 23. Fig. 8-11 and 12-15 show step described above from different views. When so assembling is good, switch axle 21 is inserted in magnetic core 24, more properly say in insertion its guidance cavity 24a. Guidance cavity 24a is configured to pass through the center through hole of magnetic core 24. At this, this through hole is in supporting or has equally in holding the region rotating asymmetric cross section of switch axle 21 and rotates asymmetric cross section. These cross-sectional configuration become correspondingly complementary so that the rotation stop portion 30a of switch axle 21 is configured in magnetic core 24. Therefore, in such as axial motion shown in Figure 16 and 17, in the way of rotating stop, guide switch axle 21 is through magnetic core 24.
Figure 18 shows a part for magnetic core 24 with vertical view. Magnetic core 24 has the guidance cavity 24a being configured to through hole in central authorities. The cross section that the cross section that guidance cavity 24a has is configured to the first area corresponding to switch axle 21 is complementary. For this reason, this cross section has circular middle portion, and the forming part of two rectangles diametrically is arranged in this middle part. By the cross section that this rotation is asymmetric, under the acting in conjunction of the cross section asymmetric with the rotation of the switch axle 21 of corresponding and complementation, realize the rotation stop portion 30 integrally constructed. By two forming parts or forming section, only make the axial motion of switch axle 21 become possibility, and rotary motion can not be produced.
