  • Publication number: 20220310310
    Abstract: A choke coil including a conductor element having a plurality of coil turns, a first terminal member adapted for electrically connecting the choke coil to a first circuit terminal of an electric circuit, and a second terminal member adapted for electrically connecting the choke coil to a second circuit terminal of the electric circuit. The first terminal member is adapted to compensate lateral dimensional variance between locations of the first circuit terminal and second circuit terminal, and the second terminal member is adapted to compensate longitudinal dimensional variance between locations of the first circuit terminal and second circuit terminal, wherein the lateral dimensional variance is perpendicular to a longitudinal direction of the choke coil extending between the first terminal member and the second terminal member, and the longitudinal dimensional variance is parallel to the longitudinal direction.

  • Patent number: 11412637
    Abstract: An apparatus for conducting heat, including a substrate for receiving one or more electric components and a thermal substance circulation system. The substrate includes a first interface for receiving a first part of the thermal substance circulation system and a second interface for receiving a second part of the thermal substance circulation system such that the substrate is, when in use, in contact with the thermal substance of the circulation system between the first and the second interface. The substrate is heat conductive for transferring heat between the one or more electric components and the thermal substance of the circulation system.

  • Patent number: 9903491
    Abstract: An explosion vent mounted to seal an opening formed on a wall of a closed space comprises a cover being dimensioned to fit on said opening and having a perimeter with an edge adapted to seal the cover against the opening with a sealing element. A spring element is arranged to hold the cover in the opening and the spring element has a direction of spring action. The cover is held by opposite retaining surfaces in the opening and the cover and he retaining surfaces are acting against the spring action of element. The sealing element is positioned against the opening so that the sealing force is directed at least partially crosswise to the direction of the spring action of the spring element.
