Arrangement for forming a thermal isolation point
The invention relates to an arrangement for forming a thermal isolation point, consisting of an isolation strip to which a prestressing force can be applied, an electrical means which produces thermal energy and has a contact surface, in particular in the form of an overvoltage protection element or a component of such an element, as well as an integral connection means, which changes when heated in a defined manner in the aggregate state, in particular a solder. According to the invention, an adapter part is provided between the isolation strip and the contact surface of the electrical means, wherein the adapter part can on the one hand be connected to the contact surface in a purely interlocking and/or force-fitting manner, and on the other hand is connected in a manner which can provide thermal isolation integrally to the isolation strip.
1. Arrangement for forming a thermal isolation point, consisting of an isolation strip to which a preloading force can be applied, an overvoltage protection element or a component thereof which produces thermal energy and has a contact surface and a material-closed connection means changing the aggregate state when heated in a defined manner, in particular a solder,
characterized in that
an adapter part is provided between the isolation strip and the contact surface of the overvoltage protection element or a component thereof, wherein the adapter part can on the one hand be connected to the contact surface in a purely form-closed and/or force-closed manner and, on the other hand, is connected to the isolation strip in a material-closed, thermally disconnectable manner,
wherein the isolation strip with the adapter part is fabricated in a first working step, and that after the production of the material-closed connection the form-closed and/or force-closed connection is realized in a mechanical manner in a second, separate step.
2. Arrangement for forming a thermal isolation point, consisting of an isolation strip to which a preloading force can be applied, an overvoltage protection element or a component thereof which produces thermal energy and has a contact surface and a material-closed connection means changing the aggregate state when heated in a defined manner, in particular a solder,
characterized in that
an adapter part is provided between the isolation strip and the contact surface of the overvoltage protection element or a component thereof, wherein the adapter part can on the one hand be connected to the contact surface in a purely form-closed and/or force-closed manner and, on the other hand, is connected to the isolation strip in a material-closed, thermally disconnectable manner,
wherein the adapter part comprises at least one crimp section or bent section which receives at least one connecting lug of the overvoltage protection element or a component thereof, and
wherein the adapter part comprises a stack of electrically connected crimp sections or bent sections, wherein the material-closed connection region is formed on one of the stack surfaces.
