The partition element 4 is doing a performance 5 , z. B. a cylindrical passage such as a through hole formed. However, the invention is neither on a cylindrical implementation nor on a through hole as a passage 5 limited.

A leader 9 a first component 1 will be performing contact through the implementation 5 in the partition element 4 from one side of the partition element 4 introduced and through the implementation 5 passed through to the other side of the partition element 4 electrically with a second component 2 to be contacted.

The leader 9 is made of an electrically conductive material, such. As copper or a copper alloy. A material such as copper has the advantage that due to its good ductility or ductility by cold working as a conductor or pin with the flange 10 can be prepared as exemplified purely schematically and greatly simplified in 2 is shown. In addition to copper or a copper alloy, the conductor 9 For example, be made of aluminum, an aluminum alloy or a combination of aluminum and copper or their alloys. However, the invention is not limited to the materials and combinations of materials for the conductor 9 limited. It can be any material or material combination for the conductor 9 can be used, which allows a production of an electrically conductive conductor with a flange. The flange 10 can be in one piece with the conductor 9 be formed as in the embodiment in 2 is shown, or attached as a separate part of this. In the latter case, the separate flange may also be made of a different material or combination of materials than the remainder of the conductor.

The diameter of the bushing 5 , z. B. through-hole, is larger than the diameter of the conductor 9 or pins but smaller than the diameter of the flange 10 of the leader 9 , as in 2 is shown.

• 2. Die Passivierungsschicht 11 ist ein eigenständiges Bauteil aus einem isolierenden Material, z. B. Keramik, auf welchem die Koppelschicht 12 mit den Kontaktbahnen 13 durch ein geeignetes Verfahren, beispielsweise Siebdruck mit Einbrennen usw., aufgebracht wurde. Damit wird es möglich den Pin 9 mit seinem Flansch 10 gasdicht auf die Koppelschicht aufzulöten. Das die Passivierungsschicht ersetzende Bauteil 11 aus isolierendem Material wird dann seinerseits mittels eine geeigneten Klebers auf die Zwischenwand bzw. Trennwand 4 aufgeklebt, wobei der Kleber auch hier entsprechend eine gasdichte Verklebung gewährleistet, oder unter Zuhilfenahme einer nicht näher bezeichneten, zusätzlichen nicht leitfähigen Dichtung auf der Oberfläche der Trennwand 4 befestigt.

In addition to screen-applied glass on a partition wall element made of steel, there are also in partition wall elements made of other materials or combinations of materials such. B. following two ways:

The coupling layer 12 and, where appropriate, the at least one conductive contact track 13 can z. B. of a conductive material or a conductive material combination such as silver, palladium, a silver alloy and / or a palladium alloy, etc. may be formed. However, the invention is not limited to the materials and material combinations mentioned. Any other, in particular, conductive material may be provided for the coupling layer and a contact track which is suitable for connecting the insulation and / or passivation layer to the flange, in particular for gas-tight connection.

The implementation of the conductor according to the invention 9 through the implementation 5 in the partition element 4 has the advantage that it provides a cost effective and robust process with inert substances. The partition element 4 can be made of metal, z. As steel, aluminum or an aluminum alloy, and / or plastic, fiber reinforced plastic.

The conductor is provided such that its flange is on the side of the insulation and / or passivation layer and the coupling layer to be attached to the coupling layer, in particular gas-tight, to be attached, for example by soldering.

In the case of a passivation layer of a glass ball-filled adhesive, which ensures the insulation, can also be dispensed with the aforementioned coupling layer in step S3. Further, in one embodiment, the passivation layer is an independent component of an insulating material, e.g. B. ceramic, on which the coupling layer 12 with the contact tracks 13 by a suitable method, such as screen printing with baking, etc., is applied, this passivation layer is used as an independent component by means of a suitable adhesive to the partition or partition z.
