The receiving portion of yoke, the mandatory guidance in the locking element to first position is caused so as to described accommodation section.Such as there is provided oblique
Face, on the inclined-plane, the locking element hoists sliding in the case where releasing locking.By interrupting excitation, the locking
Element is slid and returned in first position in being due to gravity.
The reason for symmetrical is preferably based on, the electronic mechanical relay has at least two locking elements.
A kind of preferable application field is in the high pressure onboard power system of motor vehicle.
Brief description of the drawings
Hereafter the present invention is specifically explained according to preferred embodiment.Wherein：
Fig. 1 is electromagnetic relay（Background technology）Schematic presentation,
Fig. 2 is the schematic local displaying of the electromagnetic relay in first embodiment, and
Fig. 3 is the schematic local displaying of the electromagnetic relay in second embodiment.
Embodiment
Electromagnetic relay 1 is illustrated in Fig. 1, wherein should explain basic structure and basic work side by means of the figure
Formula.The electromagnetic relay 1 includes two fixed contacts 2 and a moveable contact bridge as current collector 3.Electromagnetism relay
Device 1 also has yoke 4, magnet exciting coil 5 and ferromagnetic magnetic armature 6.The magnetic armature 6 is connected with engagement shaft 7, and the engagement shaft relies on
Contact stage clip 8 under current collector 3 works.Return spring 9 is arranged on engagement shaft 7.What dotted line was drawn is symmetry axis
Line 10 and subregion 11.There is air gap 13 between the magnetic armature 6 and the yoke 4.
In order to establish the contact between two fixed contacts 2, it is powered to magnet exciting coil 5.The magnet exciting coil establishes magnetic
, so as to magnetic current occur in yoke 4 and ferromagnetic magnetic armature 6.Cause the magnetic armature 6 in this case towards yoke 4
The movement in direction, to reduce magnetic resistance, so as to reduce air gap 13.The mobile magnetic armature 6 as a result, the engagement shaft 7
Extruded towards return spring 9 and the contact stage clip 8 extrudes current collector 3 towards two fixed contacts 2.If the connection
It is again turned on, then just disconnect the electric current by magnet exciting coil 5, and the return spring 9 extrudes the magnetic armature 6 and is returned to
In initial position.In this case, current collector 3 can be moved towards the direction of fixed contact 2 by the power of outside.For
Avoid this point, then just size design correspondingly must be carried out to the return spring 9, so that avoid not being expected to connects
Touch.
