  • Patent number: 11955257
    Abstract: A join is provided that has an electrically insulating component and two joining partners secured to one another and electrically insulated from one another by the electrically insulating component. The electrically insulating component has a surface that extends between the two joining partners. The surface defines a structure selected from a group consisting of an elevation, a depression, and any combinations thereof. The structure elongates a direct path along the surface. The structure completely surrounds at least one of the two joining partners. The electrically insulating component and/or the structure includes a glass that is at least partially crystallized.
