- This object is achieved by a machine element comprising the features of claim 8.
- Another object of the present invention is to provide a method for contacting contact pads of a machine element with respectively associated contacts of a plug, which is easy to perform and which allows a secure and accurate contacting of the individual contact pads through the individual contacts of the plug.
- the invention has the advantage that in the production of the electrical contacts between the contacts of the plug and the contact pads on the machine element only a one-time positioning of the plug is required.
- the plug and the machine element are designed such that only a single way of positioning the plug with respect to the Machine element consists.
- a secure electrical connection between the contact pads of the machine element and the contacts of the plug is made.
- the user can therefore be sure that the correct contacting of the contact pads and the contacts takes place in the plug connected to the machine element.
- Another advantage of the invention is that a release of the connection between the plug and machine element and a renewed contact is possible. This is desirable and necessary for a repair case, as this can significantly reduce the cost of a repair case.
- the present invention offers the advantage that cost-intensive, precise work steps do not take place on the individual machine elements.
- the precise contacting of the contact pads of the machine element and the contacts of the connector is achieved by using standardized connectors, thereby enabling the exact contact of the contact pads or the contacts.
- a contacting of at least one electrical element of a machine element wherein the machine element has a plurality of contact pads of the at least one electrical element.
- the plug itself has several contacts that must be connected to one of the plurality of contact pads of the machine element.

- an electrically conductive agent is introduced between the contact pads of the machine element and the contacts of the plug.
- the electrically conductive means is an electrically conductive adhesive tape or a conductive adhesive which is introduced between the contact pads of the machine element and the contacts of the plug.
- an electrically conductive adhesive tape can be introduced between the contact pads of the machine element and the contacts of the plug as an electrically conductive means only in the Z direction. This has the advantage that no electrically conductive agent must be applied to the individual contacts of the machine element or the individual contacts of the plug.

- the spring contacts have the further advantage that they can compensate for unevenness or deviating from a flat surface contours. Furthermore, it is ensured by the spring load that the electrical conductivity of the contact point over life and environmental influences, such as temperature or vibration, is only very slightly or hardly affected.
- a sealing element is provided, which is introduced between the plug and the machine element.

- the sealing element can be effected by means of a mechanical and sealing bonding between the plug and the machine element.
- the machine element according to the invention has at least one electrical element which has formed a plurality of contact pads.
- the contact pads are arranged in a mounting region for the plug on the machine element.
- the mounting area is designed such that it interacts with a positioning element on the plug.
- the interaction between the mounting area of the machine element and the positioning element of the plug is to be understood according to the key-lock principle.

First, a mounting area is provided for the exact positioning of the plug on the machine element. The plug and the mounting region of the machine element cooperate such that each contact of the plug is electrically connected to a corresponding associated contact pad of the machine element.
- the formation of a circumferential seal around the mounting area carrying the plurality of contact pads occurs when the plug is connected to the machine element.
- at least one positioning element is provided on the plug. This has the advantage that complex Justage- or positioning can be avoided to provide safe and accurate electrical contact.
- the plug itself is provided with a hold-down, which can be made robust and has the contacts of the plug to the contact pads of the at least one electrical element of the machine element.
- the hold-down z. B. by means of one or more screws on the machine nenelement be secured so that a certain contact pressure is adjusted via the tightening torque of the screws.
- a contact force acts on the adhesive tape or the conductive adhesive or the individual balls, which produce the electrically conductive contact between the contact pads of the machine element and the contacts of the plug.
- the robustness and temperature resistance of the electrical contact between the contact pads of the machine element and the contacts of the plug is made.
- the contact pressure can be achieved by the design of the distances between the mounting and contact surfaces with mechanical overlap or bias.
- the spring element can be provided as a single spring element, or the spring element can be assigned according to an embodiment of the invention each a single ball, which then makes the contact between the contact pads of the machine element and the contacts of the plug.
- connection techniques such. B. rivets, expansion dowels, press in a corresponding recess or hole or imagine the mounting area of the machine element.
- these joining techniques are to be selected, which can be solved again for repair purposes.
- the plug can be easily sealed well in a simple manner.
- the plug can be manufactured as a standardizable component in large numbers and thus cost to be mounted on individually different machine elements with electrical elements. The cost-intensive bonding to individually varying machine elements is thus reduced to the unique positioning of a standardized connector. It is also advantageous if, in case of repair, the plug can be removed and positioned again.
