  "abstract": "The present invention relates to a mounting device for mounting a nut on a screw of a battery assembly, comprising a mounting body having a receptacle extending continuously in a longitudinal direction for receiving the nut, and a holding element extending radially inwardly in the receptacle for holding the nut in a pre-mounting position distanced from the screw as well as a battery assembly comprising the mounting device.",
  "claims": [
    "1. A mounting device for mounting a nut on a screw of a battery assembly, comprising a mounting body having a cylindrical receptacle extending continuously in a longitudinal direction for receiving the nut, and a holding element extending from a cylindrical inner wall of the receptacle radially inwardly in the receptacle for holding the nut in a pre-mounting position distanced from the screw when the mounting device is fitted on the screw.",
    "2. The mounting device as claimed in claim 1, comprising a connection unit extending from the mounting body for connecting to a busbar to be fixed by the nut.",
    "3. The mounting device as claimed in claim 2, wherein the connection unit has a snap hook or clip for forming an undercut connection to the busbar.",
    "4. The mounting device as claimed in claim 3, wherein the connection unit extends radially outwardly from the mounting body with respect to the longitudinal direction.",
    "5. The mounting device as claimed in claim 4, wherein the holding element has an elastic collar inclined toward a mounting side and extending in a circumferential direction with respect to the longitudinal direction.",
    "6. The mounting device as claimed in claim 5, wherein the holding element is formed by a plurality of circumferentially mutually distanced collar segments.",
    "7. The mounting device as claimed in claim 6, wherein the holding element has two collars arranged offset from one another in the longitudinal direction.",
    "8. The mounting device as claimed in claim 7, wherein the collars are each formed by a plurality of collar segments distanced from one another in the circumferential direction.",
    "9. The mounting device as claimed in claim 8, wherein a first collar and a second collar are formed such that a flange receptacle for receiving a flange of a nut with a flange is formed between the collars.",
    "10. The mounting device as claimed in claim 9, wherein the mounting device is formed in one piece.",
    "11. The mounting device as claimed in claim 1, further comprising: at least one of: a battery module and a battery cell and a busbar electrically conductively connected via a screw connection to at least one of: a terminal of the battery module and the battery cell, wherein the nut of the screw connection is surrounded by the mounting device.",
    "12. The mounting device as claimed in claim 1, wherein the nut in the mounting device is configured to be pre-positioned; wherein the mounting device is configured to be applied to a busbar of the battery assembly; and wherein the nut is configured to be mounted on the screw.",
    "13. The mounting device as claimed in claim 3, wherein the connection unit extends from the mounting body in the longitudinal direction in the direction of the busbar on a mounting side of the mounting body facing the busbar in a mounted state on the busbar.",
    "14. The mounting device as claimed in claim 8, wherein the collar segments of a first collar extend recesses of a second collar present between the collar segments of the second collar.",
    "15. The mounting device as claimed in claim 14, wherein the collar segments of the first collar and the collar segments of the second collar partially overlap in the longitudinal direction.",
    "16. The mounting device as claimed in claim 10, wherein the mounting device has an electrically insulating material.",
    "17. The mounting device as claimed in claim 16, wherein the electrically insulating material is a plastic material.",
    "18. The mounting device as claimed in claim 11, wherein the battery assembly is a vehicle battery assembly."

  "description_excerpt": "The present invention relates to a mounting device and a method for mounting a nut on a screw of a battery assembly, and to a battery assembly, such as a vehicle battery assembly.\n\nIn the field of battery assemblies, for example vehicle batteries, it is known to assemble them from a plurality of battery modules, wherein the individual battery modules can in turn have a plurality of battery cells. In order to electrically connect the individual battery modules or the battery cells to each other, it is known to use busbars, which serve as a central distributor of electrical energy.\n\nFor this purpose, it is known to provide a bore in the busbar, through which bore a threaded region of a screw is inserted, and then to fix the busbar by means of a nut which is mounted on the threaded region of the screw and thus on the screw. In this context, the term screw is understood to mean both a screw as an individual part and a threaded bolt or a threaded pin extending in one piece from a lower part, for example a battery module or a further busbar. On the one hand, a mechanical fixation of the busbar can be achieved by this screw connection. Furthermore, the screw connection can also be provided for establishing electrical contact.",
