the electrical connection means of the electronics housing at the end, with which they are to be brought together with the plug one on this Matched coupling to quickly and easily the Establish electrical connection between the electronics side and the drive side to be able to.
the coupling is configured, for example, as a socket corresponding to the plug, with the coupling means are provided for sealing this coupling connection are.
the coupling of the electrical connection means and / or the corresponding counterpart on the drive side so constructively aligned with each other, that an easy and confusion-free insertion given is.
the housing and / or the electronics housing Fasteners for mutual attachment to each other.
Such fasteners can, for example, as tabs on the electrical housing and corresponding to the positions of the tabs on the electronics housing Threaded holes on the actuator housing, or vice versa, be formed, with the introduction of bores with threads the standard housing of the actuator with just a few additional steps would have to be modified.
a minor one would also be conceivable Modification of the shape for the actuator housing, for example this Bores (or tabs if there are corresponding bores on the electronics housing be provided) when casting the housing.
control and / or evaluation electronics is a further development of the invention high temperature resistant.
This has the advantage that the operation of the control unit, which is now located in the intake area of the internal combustion engine, where high Temperatures prevail, works reliably, so that additional insulation of the electronics housing can be dispensed with. Under high temperatures, that prevail in the engine compartment of the vehicle are, for example, those Understand temperatures in a range of 80 ° to 120 ° C.
the electronics housing insulated against high temperatures. This also ensures that electronics that are not necessarily resistant to high temperatures are used can what is achieved by appropriate insulation of the electronics housing becomes.
a combination of the two mentioned is of course also conceivable Measures that namely the control and / or evaluation electronics is designed to withstand high temperatures and the electronics housing against high Temperatures is isolated.
the electronics it is possible for the electronics to be cooled is, especially that their heat loss through the air flow in the intake area and / or by other measures (such as use of a fan) is dissipated.
the electronics housing is dust and / or Moisture-proof, these being dust and / or moisture-proof Training is also important for the clutch already mentioned.
dust and / or moisture-proof Training is also important for the clutch already mentioned.
contamination in the form of dust or the like or moisture in the housing of the actuator or in the electronics housing can penetrate in order to avoid malfunctions.
