The system has a partition element (4) and a first component (1) which is arranged on a first face of the partition element (4). The first component (1) has at least one conductor (9), and the partition element (4) has a paired feedthrough (5) for introducing and feeding through the conductor (9) and electrically contacting the conductor (9) on a second partition element (4) face opposite the first face. The conductor (9) forms a formfitting connection with the feedthrough (5) and is pressed into the feedthrough (5). ## Claims ### Claim 1 System comprising: a partition element; and a first component which is arranged on a first side of the partition element, wherein the first component comprises at least one conductor, and the partition element comprises an associated feedthrough for inserting and feeding through the conductor and for electrically contacting the conductor on a second side of the partition element located opposite the first side, wherein the conductor forms a form-fitting connection to the feedthrough and is pressed into the feed-through. ### Claim 2 (depends on 1) System according to claim 1, wherein the feedthrough is a through-hole which forms a press fit with the inserted and fed-through conductor, the diameter of the conductor being previously shrunk by means of cooling for the insertion and feeding-through in the feedthrough. ### Claim 3 (depends on 1) System according to claim 1, wherein the conductor, at least in the region of the feedthrough of the partition element, is aluminised on the outside thereof and is preferably provided with a coating made of aluminium or an aluminium alloy or connected in a form-fitting manner to an aluminium sleeve or an aluminium tube. ### Claim 4 (depends on 3) System according to claim 3, wherein the conductor, at least in the region of the feedthrough of the partition element, is provided with an oxide layer or anodised coating, the oxide layer or anodised coating being applied to the outside of the conductor or, in the case of an aluminised conductor, being applied to the aluminised outside of the conductor with a coating made of aluminium or an aluminium alloy, an aluminium sleeve or an aluminium tube of the aluminised conductor. ### Claim 5 (depends on 1) System according to claim 1, wherein the conductor is made of an electrically conductive material or electrically conductive material combination and in particular copper, a copper alloy, aluminium and/or an aluminium alloy. ### Claim 6 (depends on 1) System according to claim 1, wherein the partition element is made of metal, a metal alloy, plastics material and/or fibre-reinforced plastics material. ### Claim 7 (depends on 1) System according to claim 1, wherein the conductor is accommodated in the feedthrough of the partition element in a tight, in particular in a liquid-tight and/or gas-tight, manner. ### Claim 8 (depends on 1) System according to claim 1, wherein the conductor is constructed and arranged to electrically contact a second component on the second side of the partition element, the first component being an electrical winding, and the second component being an electronics assembly, or vice versa. ### Claim 9 Method for producing a system, comprising the following steps: providing a partition element; providing a first component with at least one conductor; equipping the partition element with a feedthrough for inserting and feeding through the associated at least one conductor, wherein the feedthrough is configured as a press fit; shrinking the diameter of the conductor at least in a section of the conductor to be inserted into and fed through the feedthrough by cooling the conductor until the conductor can be inserted into and fed through the feedthrough; and inserting and feeding the conductor from a first side into and through the feed-through of the partition element so as to provide electrical contacting on a second side of the partition element located opposite the first side. ### Claim 10 (depends on 9) Method according to claim 9, further comprising adjusting the temperature of the at least one conductor to an operating temperature of the partition element, the at least one conductor forming a form-fitting connection to and a press fit with the feedthrough of the partition element. ### Claim 11 (depends on 9) Method according to claim 9, further comprising aluminising at least one section of the at least one conductor, the section of the at least one conductor inserted into and accommodated in the feedthrough being preferably aluminised. ### Claim 12 (depends on 9) Method according to claim 9, further comprising inserting the conductor into an aluminium sleeve or an aluminium tube and connecting the aluminium sleeve or the aluminium tube in a form-fitting manner to the conductor. ### Claim 13 (depends on 9) Method according to claim 9, further comprising applying an oxide layer or anodised coating to at least one section of the at least one conductor.
