  "abstract": "A rivet assembly for securing a wire in electrical communication with a substrate having a hollow cylindrical body with a first opening at a proximal end and a second opening at a distal end. The rivet assembly further includes a wire with a portion in electrical communication with the cylindrical body. The rivet assembly yet further includes a compression mechanism configured for use selectively compressing the cylindrical body along an axial direction. Compression of the cylindrical body can cause diametric expansion of an outer diameter of the cylindrical body to retain the cylindrical body within a substrate. The rivet assembly additionally includes wire retention structure configured for holding the wire in electrical contact with the compressed cylindrical body.",

    "3. The rivet assembly of claim 2, wherein the hole extending into the compression mechanism comprises a hole extending into the mandrel head.",
    "4. The rivet assembly of claim 3, wherein the wire retention structure further comprises a compression slot cut into the mandrel head and intersecting the hole, wherein the compression slot permits flexure of the mandrel head.",
    "5. The rivet assembly of claim 4, wherein the hole extends a first length into the mandrel body and the compression slot extends a second length into the mandrel body, wherein the first length is larger than the second length.",
    "6. The rivet assembly of claim 4, wherein the wire retention structure further comprises a second compression slot cut into the cylindrical body, wherein the second compression slot is aligned with the compression slot.",
    "7. The rivet assembly of claim 4, wherein the wire retention structure further comprises a plurality of compression slots cut into the mandrel head, wherein each compression slot in the plurality of compression slots intersects the hole, wherein the compression slot is in the plurality of compression slots.",
    "8. The rivet assembly of claim 2, wherein the wire is sandwiched between the mandrel body and an inner diameter of the cylindrical body, wherein the wire retention structure is further formed by interaction between the mandrel body and the inner diameter of the cylindrical body.",

  "description_excerpt": "This invention was made with Government support under Contract No. DE-NA0003525 awarded by the United States Department of Energy/National Nuclear Security Administration. The U.S. Government has certain rights in the invention.\n\nConventionally, electrically connecting a wire to a conductive substrate can be an arduous and complicated process. A surface of the substrate needs to be abraded to remove surface oxide layers, contamination, coating layers, and the like to establish a proper electrical connection between the wire and the substrate. Attaching the wire to the substrate then involves a complicated assembly process requiring thread tapping, threaded studs, bolts, nuts, washers, two-hand access, soldering, brazing, or the like to secure the wire to the substrate.\n\nThe following is a brief summary of subject matter that is described in greater detail herein. This summary is not intended to be limiting as to the scope of the claims.\n\nIn an exemplary embodiment, provided is a rivet assembly for securing a wire in electrical communication to a conductive substrate. The rivet assembly for securing the wire in electrical communication with a substrate comprises a hollow cylindrical body with a first opening at a proximal end and a second opening at a distal end. The rivet assembly can further include a wire with a portion in electrical communication with the cylindrical body. The rivet assembly yet further includes a compression mechanism configured for selectively compressing the cylindrical body along an axial direction.",
