Description

The invention relates to a method for producing an electrically conductive connection between a first component and a second component, wherein the first component has an electrical insulation layer.

The invention further relates to an electronic assembly having a first component, a second component and an electrically conductive contact body, wherein the first component has an electrical insulation layer.

Such electronic assemblies are used for example in motor vehicles to realize a ground connection.

It is often necessary to produce an electrically conductive connection between a first component and a second component, although at least one component is formed from a comparatively poorly contactable material. There are, for example, metals which have an oxide-containing insulating layer on their surface, which makes the production of an electrically conductive connection considerably more difficult.

In particular, the electronic components used in motor vehicles must maintain their electrical properties over a long period of time, so that functional impairments and functional failures can be prevented.

For contacting components which have an oxide layer, inter alia coated flat contact springs are used. However, the aging process of such flat contact springs leads to an increase in the contact resistance, so that the risk of functional impairment or a functional failure is significantly increased by the aging process of the flat contact springs.

The invention was thus based on the object to provide a way to produce an electrically conductive connection between a first component, which has an electrical insulation layer, and a second component, which is inexpensive and whose electrical properties can be ensured over a long period.

The object is achieved by a method of the aforementioned type, wherein the method according to the invention comprises destroying the electrical insulation layer in a contacting region of the first component by mechanically stressing the contacting region of the first component with an electrically conductive contact body, producing an electrically conductive connection between the first Component and the electrically conductive contact body in the contacting region of the first component, and the manufacture of an electrically conductive connection between the electrically conductive contact body and the second component comprises.

The invention makes use of the finding that by destroying the electrical insulation layer in the contacting region of the first component by mechanically stressing the contacting region of the first component with the electrically conductive contact body, the need to circumvent the electrical insulation layer is overcome. Due to the destruction of the electrical insulation layer in the contacting region of the first component, an electrically conductive connection can be established by simply bringing the first component into contact with the electrically conductive contact body. Such an electrically conductive connection has a long service life, a low contact resistance and a low inductance. The first component may, for example, be formed completely or partially from aluminum and / or copper, wherein the electrical insulation layer is an oxide layer arranged on the surface of the first component. By destroying the oxide layer, its electrical insulation capability is resolved, so that a contact can take place.

In a preferred embodiment of the method according to the invention, the destruction of the electrical insulation layer in the contacting region of the first component by mechanically stressing the contacting region of the first component with the electrically conductive contact body comprises the mechanical deformation of the contacting region of the first component. The forming process results in that the electrical insulation layer is destroyed and thus an electrically conductive connection between the first component and the electrically conductive contact body is produced. The forming process can lead to an elastic and / or plastic deformation of the first component in the contacting region. In addition, the forming process can lead to elastic and / or plastic deformation of the electrically conductive contact body.

An advantageous development of the method according to the invention comprises generating a recess in the contacting region of the first component. Preferably, the recess is a through hole, which was produced by a subsequent processing of the first component, for example by chip removal. Alternatively, the recess may also be formed as a blind hole, wherein the blind hole does not extend over the entire material thickness of the first component. The generation of the recess in the contacting region of the first component preferably takes place mechanically. Alternatively or additionally, generating the recess in the contacting region of the first component comprises machining the contacting region of the first component and / or dividing the contacting region of the first component. The machining of the contacting region of the first component preferably comprises drilling or milling of the recess in the contacting region of the first component. The dividing processing of the contacting region of the first component preferably comprises shearing the recess in the contacting region of the first component by means of a punching machine.

In a further preferred embodiment of the method according to the invention, the generation of the recess in the contacting region of the first component comprises the thermal removal of material in the contacting region of the first component, the chemical removal of material in the contacting region of the first component, and / or the electrochemical removal of Material in the contacting region of the first component. The thermal removal of material in the contacting region of the first device preferably includes spark eroding, plasma etching, flame cutting, plasma cutting, laser cutting, laser drilling or electron beam of material in the contacting region of the first device. The chemical removal of material in the contacting region of the first component preferably comprises the chemical etching of material in the contacting region of the first component. The electrochemical removal of material in the contacting region of the first component preferably comprises the electroeroding, the electrochemical removal or the metal etching of material in the contacting region of the first component. Depending on the environmental conditions, some of the designated erosion methods may result in the formation of an electrical insulation layer. This electrical insulation layer can be destroyed in a further step, so that the recess can be used in the contacting region of the first component for producing an electrically conductive connection between the first component and the electrically conductive contact body.

In an advantageous development of the method according to the invention, a thread is produced on the recess in the contacting region of the first component. By means of the thread, the contact body can be screwed to the recess in the contacting region of the first component. The screwing of the electrically conductive contact body in the recess of the first component leads by the force of the screw flanks on the thread to a mechanical stress on the contacting region of the first component, whereby the electrical insulation layer is destroyed in the contacting region of the first component. Such a screw is also inexpensive to manufacture and insensitive to mechanical stress.

In another embodiment of the method according to the invention, the destruction of the electrical insulation layer in the contacting region of the first component by mechanically stressing the contacting region of the first component with the electrically conductive contact body comprises inserting the electrically conductive contact body into the recess in the contacting region of the first component and / or the production of a gas-tight connection between the first component and the electrically conductive contact body. The cutout in the contacting region of the first component preferably has at least sections substantially the same shape as the region of the electrically conductive contact body which is inserted into the cutout in the contacting region of the first component. By generating a gas-tight connection between the first component and the electrically conductive contact body, the formation of an electrical insulation layer, for example by a creeping oxidation of the surface of the recess in the contacting region of the first component, can be effectively avoided. Preferably, the electrically conductive contact body has a galvanized surface, which provides further protection against long-term influences of the environment. Alternatively or additionally, destroying the electrical insulation layer in a contacting region of the first component by mechanically stressing the contacting region of the first component with the electrically conductive contact body comprises joining the electrically conductive contact body to the first component, compressing the electrically conductive contact body with the recess in the first Contacting region of the first component and / or screwing the electrically conductive contact body with the recess in the contacting region of the first component.

Press and screw connections cause a forming process and thus lead to the destruction of the electrical insulation layer in the Contacting area of the first component. In addition, press and screw without high production costs can be produced and ensure a robust electrically conductive connection, which is also mechanically strong.

In a particularly preferred embodiment of the method according to the invention, producing the electrically conductive connection between the electrically conductive contact body and the second component comprises arranging an electrically conductive compensating device between the electrically conductive contact body and the second component. Preferably, the electrically conductive contact body and / or the electrically conductive compensation device are variable in length and / or at least partially elastically deformable. The electrically conductive contact body and / or the electrically conductive compensation device may be formed, for example, as a spring-loaded contact pin or include such. Characterized in that the electrically conductive contact body and / or the electrically conductive compensation device is variable in length and / or at least partially elastically deformable, distance variations between the first component and the second component can be compensated, without causing damage to the electronic module. Such distance fluctuations can occur for example due to temperature changes or material fatigue. Because distance variations can be compensated for, the risk of interruption of the electrically conductive connection between the first component and the second component is also considerably reduced since spacing enlargements can also be compensated.

The object underlying the invention is further achieved by an electronic assembly of the type mentioned above, wherein the electrical insulation layer is destroyed in a contacting region of the first component, the first component is electrically conductively connected in the contacting region with the electrically conductive contact body and the electrically conductive contact body is electrically connected to the second component.

The electronic module according to the invention provides an electrical connection between a first component and a second component, which has a low contact resistance and a low inductance value. In addition, the electronic assembly according to the invention allows the provision of a defined potential, which is largely independent of EMC (electromagnetic compatibility) influences.

In a preferred embodiment of the electronic module, the electrically conductive contact body is arranged in a recess in the contacting region of the first component. Preferably, the electrically conductive contact body is pressed and / or screwed to the recess in the contacting region of the first component. The recess may be formed as a through hole or as a blind hole. For example, the recess has a concave, convex or cylindrical shape. By pressing and / or screwing the electrically conductive contact body with the recess in the contacting region of the first component, a robust and resistant connection is provided, which can also be designed as a gas-tight connection. If the connection is made gas-tight, the risk of the formation of an electrical insulation layer, for example due to creeping oxidation, is considerably reduced.

The electronic assembly according to the invention is further developed advantageous in that between the electrically conductive contact body and the second component, an electrically conductive compensation device is arranged. The compensation device is preferably configured to compensate for or compensate for changes in the distance between the first component and the second component. Thus, it can be avoided that a reduction in the distance between the first component and the second component leads to an excessive stress on the components of the electronic assembly, so that damage is avoided. In addition, the electrically conductive compensation device is also set up to compensate for increases in distance between the first component and the second component. Thus, the risk of disconnection due to an increase in distance is significantly reduced.

In a particularly preferred embodiment of the electronic assembly according to the invention, the electrically conductive contact body and / or the electrically conductive compensation device are designed to be variable in length. The length variability allows the electrically conductive compensation device to compensate for changes in the distance between the first component and the second component. Preferably, the electrically conductive contact body and / or the electrically conductive compensation device has a spring which biases a contact pin in the direction of the first component or of the second component. Alternatively or additionally, the electrically conductive contact body and / or the electrically conductive compensation device are formed at least partially elastically deformable. For example, the electrically conductive contact body and / or the electrically conductive compensation device on one or more elastically deformable struts. Characterized in that the electrically conductive contact body and / or the electrically conductive compensation device are formed elastically deformable, the electrically conductive contact body and / or the electrically conductive compensation device can be clamped with other components of the electronic module.

In another preferred embodiment of the electronic assembly according to the invention, the first component is at least partially formed of aluminum or copper. Alternatively or additionally, the electrical insulation layer is formed as an oxide layer. The oxide layer on the surface of aluminum and copper components complicates the contacting of such devices to a considerable extent, since to ensure an electrically conductive connection, the oxide layer must be overcome. Since in the electronic module according to the invention, the electrical insulation layer is destroyed, and aluminum or copper components can be contacted easily.

In an advantageous development of the electronic assembly according to the invention, the surface of the electrically conductive contact body is at least partially galvanized. The galvanized surface of the contact body allows protection against long-term environmental effects. Alternatively or additionally, the surface of the compensation device is partially or completely galvanized. Thus, the electrically conductive compensation device is protected against long-term environmental influences.

The electronic assembly according to the invention is further developed advantageously in that the first component and the electrically conductive contact body have a common contact surface, wherein the contact surface is preferably at least partially concave, cylindrical or convex. Concave, cylindrical and convex recesses and body can be produced without a high manufacturing cost and thus allow a secure and robust contact without a high cost.

In a further advantageous embodiment of the electronic assembly according to the invention, the connection between the first component and the electrically conductive contact body is tool-less and non-destructive reversibly detachable. Preferably, one, several or all connections between the other components of the electronic module are tool-less and non-destructive reversibly detachable. The tool-less and non-destructive reversible detachable design of the compound or the compounds, the electronic module can be disassembled without damage. This allows, for example, the maintenance of the electronic module or the replacement of individual components of the electronic module. Due to the fact that component replacement can take place in the event of a functional failure of a single component of the electronic module, the maintenance and maintenance costs are considerably reduced.
