Definitions
- the invention relates to a device for contacting a circuit board electronic control device of an actuator, in particular a throttle valve an internal combustion engine of a motor vehicle, the control device and the actuator form a structural unit, with on a first Board arranged contacts and connected to a second board, contacts conductively connected to the contacts of the first circuit board.
- Throttle valves used are usually one or more electronic circuit boards Control device arranged in a pot-shaped housing.
- the housing is in one piece with a throttle body that supports the throttle valve manufactured and is closed by a lid.
- the throttle body has a flange for direct screwing to the internal combustion engine.
- connection contacts for the vehicle electrical system and for Signal lines arranged. This makes the throttle body with all components required to regulate the output, such as the circuit boards and the Lid with the connection contacts very compact.
- the circuit boards and the connection contacts of the cover are on their contacts electrically contacted with each other and with a servomotor for the throttle valve. Because the contacting in particular in the throttle body the printed circuit boards withstand high temperatures and vibrations the contacts are usually connected to each other by laser welding. However, laser welding is very complex and leads to a very high level costly assembly of the throttle body.
- the invention is based on the problem of a device of the type mentioned Art to design so that the electrical connection of the contacts designed as inexpensively as possible and that the connection then high Withstands temperatures and vibrations particularly reliably.
- the circuit board is contacted in an area in which there are no mechanical loads on the connection point. Therefore, vibrations do not cause the contacts to rub against each other and not to destroy them. Tolerances between the components and Relative movements of the components to each other are from the connecting lines balanced.
- the contact device according to the invention thus has a particularly high reliability. As for the contact device according to the invention no solder joints are required, this is especially for use suitable for internal combustion engines of motor vehicles.
- the pretensioning of the holding part could, for example, be one on the first Printed circuit board arranged bracket.
- the holding part is an additional step when joining the boards together required.
- the holding part is preloaded according to an advantageous method Further development of the invention without additional assembly effort when Assemble the boards when between the second board and the Holding part a spring element for biasing the holding part against the first Circuit board is arranged.
- the device according to the invention is particularly cost-effective, if the elastic connecting cables are printed on a foil Conductor tracks are formed.
- the manufacture of the holding part as a separate component only leads to an insignificant one Increasing the manufacturing costs of the device according to the invention, if the holding part and the second board are made of the same plastic and with each other via a thin bridge in relation to their material thickness are connected.
- the web can optionally be used as a predetermined breaking point between the second board and the holding part serve, or elastically, a relative movement the components are designed to enable each other.
- a relative movement of the holding part with respect to the first board can be according to another advantageous development of the invention, simply avoid if the holding part guide pin and the first component the guide pin has corresponding holes.
- the holding part is according to another advantageous development of the invention reliably biased against the first board when the second board has a guide element for the spring element.
- the device according to the invention is structurally particularly simple, if the spring element is a helical spring and the guide element is a sleeve is.
- the contacts could each be designed as contact plates, for example his. Opposing contact plates could be used for contacting pretension vertically against each other.
- this design requires very high preload forces to avoid friction between the contacts and a particularly precise guidance of the holding part with respect to the first Circuit board. Friction between the contacts would result in destruction of the electrically conductive connection. A friction between the contacts
- the contacts of the second board are pin-shaped and the contacts of the first board against the contacts of the second board are biased.
- the side preload can be very simple by appropriate shaping of the contacts of the first board respectively.
- FIG. 1 shows a throttle valve connector 1 with a load adjusting device 2.
- the load adjustment device 2 has a channel 3 penetrating Control shaft 4.
- On the control shaft 4 is one for controlling a free cross-sectional area of the channel 3 serving throttle valve 5 attached.
- the control shaft 4 is of a in a cup-shaped housing 6 of the throttle body 1 arranged actuator 7 pivoted. Furthermore is in the housing 6 a control device 8 for controlling an electric motor, not shown arranged.
- the actuator 7 can be driven with the electric motor and thus pivot the control shaft 4.
- the cup-shaped housing 6 of the throttle valve connector 1 is closed by a cover 9.
- the throttle valve connector 1 has two bearings 10, 11 for the actuating shaft 4 on. At the end of the control shaft 4 opposite the control gear 7 a control lever 12 attached. To the bearing 11 of this end of the control shaft 4th an emergency running spring 13 and a return spring 14 are arranged concentrically. The return spring 14 and the emergency running spring 13 are each in the form of leg springs designed and arranged in a shaft-like housing 15. The housing 15 is closed by a cover 16.
- the control device has two boards 17, 18 arranged one above the other the cover 9, a socket 19 is arranged with which the control device 8 to a vehicle electrical system, not shown, for the power supply and / or for data exchange (for example via a CAN bus) is connected.
- the two boards 17, 18 are with an inventive Device 23 electrically connected to each other.
- a holding part 20 is arranged between the two Boards 17, 18, a holding part 20 is arranged.
- the holding part 20 is one spring element 21 designed as a helical spring against upper board 18 biased and is with elastic connecting lines 22 to the lower board 17 connected.
- the device 23 according to the invention is greatly enlarged in one Partial section through the holding part 20 and a partial area of the upper board 18 shown.
- the electrical connection lines 22 are up to on the holding part 20 arranged contacts 24 out.
- the contacts 24 of the holding part 20 are connected to contacts 25 of the upper board 18.
- Figure 2 shows that the spring element 21 by a as Sleeve trained guide element 26 is guided vertically.
