Patent number: 11936152Abstract: A method is provided for electrically conductively connecting a contact part to a conductor having a multiplicity of individual wires includes inserting the conductor into a cavity in the contact part and lowering a tool for friction stir welding onto the contact part. The tool for friction stir welding is moved on the contact part in a plane, thus giving rise to a planar cohesive connection between the contact part and the conductor. In this way, a direct cohesive connection of a stranded conductor and a contact part is produced without the need for an additional part such as a sleeve, for example, to prevent the stranded conductor from “sticking out”.Type: GrantFiled: July 23, 2020Date of Patent: March 19, 2024Assignee: NEXANSInventor: Helmut Steinberg

Patent number: 11788903Abstract: An optical temperature sensor head having an optical fibre and a sensor material, which is optically connected to a free end of the optical fibre. The free end of the optical fibre has an overmould made of a plastics material, which engages over a free end of the optical fibre and forms a protective body. A transparent window is arranged in the protective body. The window permits an optical connection with the free end of the optical fibre. Luminescence radiation from a sensor material can enter the optical fibre. The protective body has the effect that the temperature sensor head is mechanically stable and is insensitive to environmental influences.

Patent number: 10594103Abstract: A method is disclosed for moisture tight covering a connection point between an electrical conductor. The method includes exposing the conductor at its end by removing the insulation and subsequently electrically conductively connecting the end of the conductor, from which the insulation has been removed, to the contact element. After the connection point is finished, a foil of insulation material is positioned underneath the connection point, where the foil rests against the insulation of the conductor and at least partially against the contact element. Subsequently, a sealing material capable of hardening is applied from above onto the conductor, wherein the sealing material is flowable during its application and subsequently changes over by hardening into a mechanically stable state which extends beyond the insulation of the conductor and beyond the contact element and is connected tightly to the foil.Type: GrantFiled: August 26, 2013Date of Patent: March 17, 2020Assignee: NEXANSInventors: Helmut Steinberg, Thomas Noetzel, Udo Mayer
