Definitions
- the invention relates to a relay, in particular for a starting device of an internal combustion engine, according to the preamble of the independent claim.
- Relays for starting devices of internal combustion engines are e.g. known from DE 411 72 42 Cl.
- the known relay comprises a relay coil with a magnet armature that passes through
- This known relay has the disadvantage, inter alia, that the magnet armature can be lost, which makes the handling of the relay during assembly to the starting device difficult.
- Another disadvantage is that only a contact return spring releases the contact element from the mating contacts and this to open the circuit of the Starter motor is not sufficient for so-called contact welding under adverse conditions.
- the relay according to the invention with the features of the independent claim, it is possible on the one hand to design the relay so that the magnet armature is captive and on the other hand to use the vibrational energy of the magnet armature after switching off the relay coil to open the circuit of the circuit of the starter motor.
- a coupling element is provided which connects the shift rod and the magnet armature with one another to a limited extent.
- the coupling element is arranged such that the magnet armature can be displaced to a limited extent in the return direction with respect to the shift rod. This makes it possible for the magnet armature to take the selector rod with it via the coupling element and thus to open the starter motor switch, in particular under unfavorable circumstances, for example during contact welding.
- the shift rod has one free end face, which serves as a stop for a plunger attached to the magnet armature. This makes it possible for the armature to press on the plunger on the switching rod during the switching-on process and thus press the contact element against the counter-contacts to close the starter motor switch.
- the coupling element partially surrounds the shift rod and the plunger. This is particularly advantageous if the coupling element is connected to the shift rod by means of a snap connection, since the coupling element can then be pushed more easily onto the shift rod.
- a simple and inexpensive variant of a connection between the coupling element of the switching rod and the plunger is given in that the coupling element surrounds the switching rod and the plunger in a sleeve-like manner.
- a sleeve-shaped coupling element is particularly advantageous if the coupling element consists of a sleeve-shaped sheet. This also makes it easier to slide it over the shift rod or tappet.
- the coupling element engages behind either a corresponding counter-projection on the plunger or a corresponding counter-projection on the magnet armature. If the magnet armature does not have a plunger, the only way to attach a projection is the magnet armature itself. If, on the other hand, the magnet armature has a plunger, it is advantageous to attach the protrusion to the plunger since this does not make the coupling element too large.
- the coupling element is designed such that the shift rod is guided through the magnet armature in a through opening.
- the coupling element is designed in sections in such a way that it leads the shift rod in a through opening through the magnet armature, then the resulting or existing collar can be used to ensure that a spring element is attached to it supports and presses a contact element into a position remote from the coupling element.
- FIG. 1 shows a first exemplary embodiment of a relay according to the invention in a longitudinal sectional view
- Figure 2 shows a second embodiment of a relay according to the invention in a longitudinal sectional view.
- FIG. 1 shows a first embodiment of a relay 10 according to the invention, in particular for a starting device of an internal combustion engine.
- the relay 10 has a relay coil 13 on which a magnetic core 16 is arranged.
- the relay coil 13 is inserted into a housing 19.
- a movable magnet armature 22 is associated with the relay coil 13, with which a plunger 25 is firmly connected.
- a switching rod 31 In a through opening 28 of the magnetic core 16 is a switching rod 31 by means of a sleeve
- Elements 34 axially made of insulating material, which also serves as a receptacle for a contact element 37.
- the contact element 37 With the switching rod 31, the contact element 37 is also axially displaceable in the through opening 28. When the contact element 37 reaches an end position, it comes into contact with Mating contacts 40 of the relay. The contact of the contact element 37 with the mating contacts 40 closes a circuit of a starter motor, not shown, so that the starter motor can be energized by a battery via the contact element 37.
- the magnet armature 22 is drawn into the relay coil 13 by a magnetic field which extends over the housing 19 and the magnet core 16 and the magnet armature 22 until it rests against an end face of the magnet core 16. This retraction movement determines a switch-on direction.
- the plunger 25 is thus moved in the direction of the switching rod 31 and finally comes into contact with a free end face 43 of the switching rod 31 and thus exerts a pushing force on the switching rod 31 and the contact element 37 connected to it, see FIG. 2.
- a coupling element 46 which connects the switching rod 31 and the armature 22 to one another to a limited extent.
- the coupling element 46 is arranged in such a way that the magnet armature 22 can be displaced to a limited extent in relation to the switching rod 31 in a reset direction which is opposite to the switch-on direction.
- this is achieved in that, on the one hand, the coupling element 46 is not displaceably connected to the shift rod 31 and, on the other hand, the coupling element 46 has a projection 49 which engages behind a corresponding counter-projection 52 on the plunger 25.
- the counter projection 52 can be freely displaced between the projection 49 and the free end face 43.
- the shift rod 31 is connected to the coupling element 46 by means of a snap connection 55.
- the coupling element 46 surrounds the shift rod 31 and the plunger 25 partly in each case and due to the essentially cylindrical shape of the coupling element 46, the coupling element 46 surrounds the shift rod 31 and the plunger 25 in a sleeve-shaped manner.
- a spring element 58 is provided which is supported on an end section 61 of the coupling element 46, which faces away from the magnet armature 22, and presses the contact element 37 into a position remote from the coupling element 46. Before the contact element 37 electrically connects the two mating contacts 40, this removed position is determined by a stop 64 which is fixedly connected to the switching rod 31, see also FIG. 1. On the other hand, if the switching rod 31 is in the switched-on position, the position removed from the coupling element 46 becomes the counter contacts 40 determined.
- the spring element 58 is supported on an inside of the sleeve-shaped element 34 and on the other hand on an end face of the end section 61 of the coupling element 46.
- the spring element 58 in the exemplary embodiment according to FIG. 2 is supported on a collar 67 of the coupling element 46.
- the coupling element 46 can guide the switching rod 31 in the through opening 28 of the magnetic core 16, the end section 61 of the coupling element 46 is in its
- the coupling element 46 is expanded in a sleeve-shaped manner, that on the one hand the spring element 58 is received within a sleeve-shaped extension 70 and on the other hand the sleeve-shaped extension 70 has a suitable outer diameter, so that there is a suitable guidance of the coupling element 46 in the through opening 28 results.
- the magnet armature 22 is drawn into the relay coil 13 and presses with its plunger 25 onto the switching rod 31.
- the coupling element 46 connected to the switching rod 31 presses the contact element 37 against the two mating contacts 40 via the spring element 58 and the sleeve-shaped element 34
- welding can occur between the contact element 37 and the mating contacts 40. This welding is among the most unfavorable
- the starter motor is energized unnecessarily long, which can lead to overloading and ultimately to failure of the starter motor.
- the start switch is opened in the relay 10 according to the invention, the energization of the relay coil is initially ended 13, as in the known relay 10.
- the magnet armature 22 is then pressed into its starting position by a restoring force.
- the restoring force can be generated, for example, as shown in both exemplary embodiments, by a restoring spring 73 within the magnet armature 22.
- the mangetanker 22 which is finally accelerated by the restoring force, takes the switching rod 31 in the relay 10 according to the invention via the coupling element 46 and this, via the stop 64, the contact element 37 and finally tears it free from the two mating contacts 40.
- the plunger 25 has a plunger collar 76 which, when the magnet armature 22 moves in the reset direction
- Coupling element 46 takes along its projection 49. A pulse is thus transmitted via the coupling element 46 and the snap connection 55 to the switching rod 31 and then via the stop 64 to the contact element 37 and thus this contact element 37 suddenly torn away from the mating contacts 40.
- the coupling element 46 it is also possible for the coupling element 46 to have a radially outwardly directed projection 49 which engages behind a counter-projection 52 which is equivalent to the counter-projection 52 of the plunger 25 in a recess 79 of the magnet armature 22.
- the restoring force can be generated, for example, in that a spring element generates this restoring force outside the magnet armature 22.
- the coupling element 46 according to FIG. 1 represents an injection molded part made of plastic.
- the coupling element 46 according to FIG. 2 is a variant made of sheet metal, which is produced by rolling a sheet metal strip.
