Definitions

  • the invention relates to an electromagnetic adjustment device, in particular for camshaft adjustment, with the features of the preamble of patent claim 1.
  • Such an electromagnetic camshaft adjusting device is, for example, from DE 20 2009 006 940 U1 known.
  • This device has a connector housing in which a stationary coil unit and a sensor unit are located.
  • the coil unit and the sensor unit each have connections and are connected to contact pins within a plug section of the housing via electrical lines in a manner not described in detail.
  • the connector housing sits on an actuating unit with an axially movable armature which, when the coil unit is energized, is axially movable and interacts with a tappet of the camshaft adjusting device of a motor vehicle.
  • the housing has a cylindrical housing shell which surrounds a coil unit.
  • the cylindrical housing is filled with a plastic potting material in such a way that the coil unit is encapsulated. A lower end area of the coil unit still protrudes from the potting material.
  • the coil unit is connected to a connecting line which leads to contact pins that are externally accessible on the connector housing. These contact pins are located in the cavity of a plug flange that is integrally formed on the plug housing.
  • a sensor unit is attached to the housing in such a way that it is approximately half enclosed by the potting material and its lower half protrudes into a cavity in the connector housing. The sensor unit interacts with a disk-shaped permanent magnet so that when the armature moves axially, a changing permanent magnetic field can be detected by the sensor unit and this can be fed to subsequent electronic processing.
  • a particular challenge with such electromagnetic camshaft adjusting devices is the relatively complicated assembly of the individual components within the connector housing and, above all, the contacting of the coil unit and the sensor.
  • a proper sealing or tightness of the contacts must be ensured because the coils are open in the manufacturing process Oil of the motor vehicle. It is therefore necessary to make the individual contacts between the coils and the contact pins of the connector housing on the one hand and between the sensor unit and the contact pins of the connector housing on the other hand absolutely oil-tight, because the contacts that are regularly welded in such electromagnetic camshaft adjusting devices must not come into contact with oil. Such a contact of the contacts with oil would lead to unwanted copper corrosion. For this reason, these welded contacts are regularly sealed again separately by means of a further potting material after the sensor has been installed in the connector housing, in that this further potting material is applied to the contacts that are still exposed.
  • the present invention is defined in claim 1 and has the aim of avoiding the disadvantages described and developing the electromagnetic adjusting device specified at the beginning in such a way that the individual components and in particular the contacts are designed to be absolutely oil-tight.
  • the connector housing consists of a potting material in which both the coil unit and the sensor and the associated electrical lines and connections are completely embedded in the potting material.
  • This measure ensures that the critical components and contacts or electrical lines of the electromagnetic adjustment device are integrated in an absolutely oil-tight manner in the potting material of the connector housing, with the additional advantage that a finished, manageable assembly with all electromagnetic components is made available, which only needs to be placed on an actuation unit of the electromagnetic adjusting device and fastened there in order to provide a functional electromagnetic adjusting device.
  • Such an electromagnetic adjustment device is characterized by simple assembly of the electromagnetic actuator and absolute oil-tightness.
  • the electrical lines between the coil unit and the contact pins externally accessible from the connector housing and / or the electrical lines between the sensor unit and the contact pins externally accessible from the connector housing are designed as a metal stamped grid and are pre-bent and inserted into an injection mold , in which the connector housing is then produced by overmolding.
  • the main advantage of such prefabricated leadframes is that on the one hand the coil unit can already be connected to them and thus the coil unit with the leadframe forms a prefabricated structural unit that is very easy to handle and can be inserted into the injection mold.
  • This lead frame with attached and connected sensor unit also forms a pre-assembled structural unit that is easy to handle.
  • the lead frames are pre-bent accordingly and can easily be inserted into the injection molding tool of the connector housing. This also decisively simplifies the manufacturing process of the electromagnetic adjustment device.
  • two coils are provided for the coil unit. These two coils are each provided with a plus connection and a ground connection, it being possible for the two ground connections to be connected to one another.
  • the two plus connections and the common ground connection are then connected to the three mentioned lines of the lead frame. According to the invention, these three lines of the punched grid are then in turn connected to three contact pins of the plug of the electromagnetic camshaft adjusting device.
  • the electromagnetic adjusting device and in particular the camshaft adjusting device is a so-called 1-pin actuator for actuating only a single tappet
  • the coil unit can also have only a single coil. In this case only two lines (plus and ground connection) would be necessary.
  • the coil unit has at least one coil which is wound onto a coil carrier.
  • the coil carrier has an upper and a lower collar, the two collars having different axial heights.
  • the widened collar which can be the upper collar, for example, at least two contact pins are used as connections, each of which is electrically connected to the coil wire ends of a coil wire of the coil. It has proven to be beneficial to weld the contact pins to the coil wire ends.
  • other electrical connection methods are also possible, e.g. B. soldering, electrically conductive gluing or the like.
  • the armature of the actuation unit is designed as an armature pin which centrally engages at least partially in a coil of the coil unit when the connector housing is placed on the actuation unit.
  • two such anchor pins are provided.
  • the actuating unit has also been found to be expedient to provide the actuating unit with shells in the shape of a segment of a circle made of metal, which at least partially engage in a cavity of the plug housing surrounding the coil unit.
  • These circular segment-shaped shells made of metal which can also be designed as guide plates, are used to guide the electromagnetic field that is generated when the coil unit is energized and thus when the electromagnetic camshaft adjusting device is in operation.
  • the connector housing has a plate-shaped base part into which sockets are injected.
  • the openings of these sockets are aligned with corresponding fastening openings on the actuation unit, so that the plug housing can be screwed to the actuation unit in a simple manner.
  • the connector housing is closed by a cover.
  • a cover This can be a plastic cover that is attached to the connector housing by means of laser welding or other fastening methods.
  • the coil unit can have at least one coil body, the coil support collars of which are provided with circumferential sealing lips, these sealing lips being encapsulated by the sealing compound of the connector housing during manufacture of the connector housing, so that a secure and optimal seal is achieved.
  • the same reference symbols designate the same parts with the same meaning.
  • the connector housing and the integrally molded base part and the integrally molded connector flange are each shown transparently in order to make the components in the connector housing visible and to facilitate understanding of the description of the figures. It goes without saying that this connector housing does not, of course, have to be transparent in reality. Any color design of the connector housing is possible. A particularly preferred color variant of the connector housing is that it consists of black potting material.

  • the electromagnetic camshaft adjusting device 1 has a connector housing 10 made of plastic potting material, onto which a plate-shaped bottom part 11 is integrally formed.

  • the connector housing 10 is closed on its top by a cover 15, preferably also a cover made of plastic.
  • This cover 15 is placed on the connector housing 10 in a sealing manner.

  • a sensor unit 30 can be, for example, a Hall sensor which, when the electromagnetic camshaft adjusting device is in operation, is intended to detect an axial position of the aforementioned tappets 100, 101 or the armature 90 that is operatively connected to these tappets 100, 101.
  • This sensor unit 30 has, for example, three connections 31, 32, 33, which can be designed as contact pins of an integrated circuit of the sensor unit 30. These connections 31, 32, 33 are electrically connected to the lines 41, 42, 43 of the lead frame, for example again by welding.

  • This actuating unit 80 has a base plate 81 which is made of metal, for example, and which corresponds approximately to the dimensions of the base plate 11 of the plug housing 10.

  • FIG. 5 Another special feature is that the sensor completely encapsulated with the potting material of the connector housing 10, that is to say the sensor unit 30, protrudes somewhat beyond the base area of the base plate 11 by a protrusion D. This is necessary so that the sensor unit 30 is optimally arranged to be movable with the armatures 91, 92 and can optimally detect permanent magnets and their magnetic fields, which are not shown, in the figures for better clarity. It also shows Figure 5 that the sockets 13 also protrude slightly beyond the base of the base part 11. These sockets 13 can thus serve in a simple manner as an adjustment aid in that this protruding area of the sockets 13 can engage in the aforementioned openings 82 of the actuating unit 80.
