The invention further relates to a device consisting of a series arrangement of a housing for an electronic control unit, and a consumer, in particular an electric motor, and a method for mounting such a device.

State of the art

In devices of the type mentioned, it is known to produce the electrical contact from a consumer to a circuit carrier via contact elements, which consist essentially of metal pins or lines. The lines are first encapsulated with a plastic. The resulting contact element is inserted in the manufacture of the housing or a corresponding housing part in the injection mold and molded with. The finished housing part thus contains after completion of the manufacturing process already the contact element as an integral part. The contact element corresponds in its length to the distance between the housing and the consumer, so that the contact element protrudes far beyond the housing under certain circumstances. As a result, the handling of the housing in the course of further assembly, and the transport and storage of the housing difficult.

From the DE 197 27 477 A1 is such a contact element known. It has an integrally formed body of a dielectric material which surrounds the contact lines substantially over their entire length. The ends of the contact lines on both sides of the contact element are exposed and can be contacted in each case via corresponding mating connector or contact sockets with the control circuit or the consumer.

From the EP 1 955 927 A1 is an alternative contact between an electric motor and a control unit for motor-assisted steering systems in vehicles known. As a circuit carrier, the control unit has a stamped grid, from which contact elements are formed directly. Contact lines from the electric motor are guided by a cover of the control unit to the contact elements and contacted by the formed in the contact elements spring terminals. However, this embodiment is limited to punched grid as a circuit carrier.

Disclosure of the invention

A contact element is proposed which is suitable for establishing an electrical contact between a circuit carrier arranged in a housing and a consumer arranged outside the housing. For this purpose, the contact element has at least one contact pin, which is suitable to be inserted into a corresponding contact opening of the circuit carrier and / or the consumer. Alternatively or additionally, the contact element has at least one receiving means which is suitable for receiving a contact line from the circuit carrier and / or the load in order to produce an electrical contact. The contact element is suitable to be at least partially introduced into a passage opening of the housing.

The advantage of the invention over the prior art is to provide a contact element which is designed as a separate component and can be inserted into a suitable existing opening of the housing of the control unit.

On the first side of the contact element pointing into the interior of the housing, the electrical contact to a circuit carrier is produced in the interior of the housing. At the second, facing the outer surface of the housing side of the contact element of the electrical contact to at least one contact line is made by the consumer. The contact element according to the invention is preferably formed as a flat stamped sheet metal part, which consists of a material having a high electrical conductivity, for example copper. It is thus simple, inexpensive and time-saving in the production.

In one embodiment of the invention, the contact element has at least one contact pin on its first side and / or on its second side. The contact pin can for example be inserted into a corresponding contact opening of a circuit carrier in order to produce an electrical contact from the contact element to the circuit carrier.

The contact element according to the invention is preferably inserted or plugged into the housing. The contact element is thus not integrally formed with the housing, but can in a later process step are introduced into the housing. The arrangement of the contact element in a passage opening of the housing also simplifies the assembly of an arrangement according to the invention, since the contact lines of the consumer need not be guided through an opening of the housing.

In order to ensure a secure hold of the contact element in the housing even with vibrations, shocks and temperature fluctuations, ie the conditions that prevail in a motor vehicle, the contact element preferably has one or more projections on its side surfaces. These projections engage in the insertion opening or insertion of the contact element in the passage opening of the housing in the side walls of the passage opening and thus cause a frictional connection of the contact element with the housing. In a particularly preferred embodiment, the side walls of the passage opening are provided with corresponding grooves, so that there is a latching connection between the contact element and the housing.

The contact pin on the first and / or second side of the contact element is preferably designed as a press-in contact. He has to a lateral thickening. If the contact pin is pressed into a corresponding contact opening of a circuit carrier, a plastic and / or elastic deformation of the circuit carrier and of the contact pin occurs in the region of the thickening, whereby a reliable electrical contact is established.

Particularly preferred is a clip or spring-like design of the receiving means. Due to the spring action, a contact line can be held on the one hand and electrically contacted on the other hand. Thus, no additional soldering or welding is necessary. In addition, such a connection is subsequently released again, which can be done in a simple way, an exchange or maintenance of items.

In a particularly preferred embodiment of the invention, the contact element has on its first side a contact pin which is suitable to be inserted into a corresponding contact opening of the circuit carrier in order to establish an electrical contact with the circuit carrier. On its second side, the contact element on a receiving means which is adapted to receive a contact line from the consumer and to make electrical contact. This embodiment has the advantage that a particularly simple contacting is achieved in which no additional lines or connector elements are needed. It can also be made a solid and secure contact with the circuit carrier inside the housing via the contact pin, while the contact line is received by the consumer in a simple manner by the receiving means.

Furthermore, the invention relates to a device consisting of a housing for an electronic control unit, and a consumer, wherein the electrical contact between the load and the housing is made via a contact element according to one of the embodiments described above. The device according to the invention has a housing with at least one circuit carrier arranged therein and a consumer. The consumer has at least one contact line which is suitable for electrical contacting of the circuit carrier arranged in the housing. According to the invention, the housing has at least one leadthrough opening into which a contact element is introduced. An electrical contact is made between the first, in the interior of the housing facing side of the contact element and the circuit carrier. The contact line from the consumer is in electrical contact with the second, facing the outer surface of the housing side of the contact element. As a result, the electrical contact is made by the consumer to the circuit carrier.

The advantage of such a device is that it is easy to install, since no complex additional parts, such as contact sockets, in the control unit and / or in the consumer are required for contacting. Furthermore, the invention, due to the reliable electrical connection in a. Environment with high demands on stability, such as can be used in a motor vehicle.

The axial length of the contact element is preferably dimensioned so that it is flush with the outer surface of the housing. This simplifies the handling of the housing during assembly, since no protruding contacts must be considered.

In a preferred embodiment of the device according to the invention, at least one contact element has on its first side facing the interior of the housing a contact pin which is inserted into a corresponding contact opening of the circuit carrier, whereby the electrical contact to the circuit carrier is established.

The circuit carrier is designed, for example, as a printed circuit board or as a stamped grid. The contact opening can, for example, as a through hole be educated. The contact opening may be metallized on its inner surface or have a hollow cylindrical metal sleeve.

The contact element has a receiving means on its second side facing the exterior of the housing. At least one contact line of the consumer engages with its end in the receiving means of the contact element, whereby an electrical contact is made by the consumer to the circuit carrier in the housing. This embodiment has the advantage that no additional lines or connector elements are necessary for contacting.

Preferably, the housing consists of a bottom part and a cover part, wherein the bottom part contains the at least one passage opening into which the contact element according to the invention is introduced.

The contact element preferably has a contact pin which projects into the interior of the housing. The circuit carrier is received in the bottom part. Preferably, the circuit carrier has at least one contact opening, which is arranged after the mounting of the circuit carrier in the bottom part of the housing in the region of the passage opening of the housing, so that the contact pin of the contact element can be inserted into the contact opening of the circuit carrier. The cover part can be placed on the bottom part and thus closes the housing.

Further advantages of the use of a contact element according to the invention arise when mounting a device according to the invention by the following method.

First, the contact element is introduced into a passage opening of the housing. If a plurality of contact elements are provided, first all contact elements are introduced into the corresponding passage openings.

Then the circuit carrier is mounted in the housing. In this step, the electrical contact between the contact element or the contact elements and the circuit carrier is already made. This is done, for example, by inserting a contact pin on the first side of a contact element into a corresponding contact opening. Thereafter, the housing, in the case where it is constructed in several parts, be closed.

In the next step, one or more contact lines are guided by the consumer to the corresponding second side of the respective contact element and contacted there. If, for example, a contact element on its second side has a forceps-like or spring-contact-type receiving means, the end of the corresponding contact line is inserted into the receiving means and the electrical contact is established by the spring action.

This mounting method has the advantage that the contact lines themselves do not have to be guided through openings in the housing, but are contacted directly with the second side of the contact element, ie on the outside of the housing. This makes it possible to contact the leads coming from the consumer "blind" in the housing, which considerably simplifies the assembly process, since the housing can be prefabricated.
