Abstract
A method for manufacturing a slipring module comprising a plurality of sliding tracks and an insulating body. The method includes: making a monolithic sliding track component preferably by a 3D printing process. The monolithic sliding track component comprises a plurality of sliding tracks, multiple connector for electrically connecting the sliding tracks, and at least one strut for mechanically interconnecting the sliding tracks and the connector to form a monolithic sliding track component; inserting the monolithic sliding track component into a mold; filling the mold with an insulating material such as a plastic material, and curing the plastic material; removing the molded product forming a slipring module from the mold, and removing the at least one strut from the slipring module.

A monolithic sliding track component comprising:
- a plurality of sliding tracks, each shaped as a hollow cylinder having an outer side, an inner side, and a center axis,
- a plurality of struts, each strut of said plurality of struts corresponding to a different sliding track of the plurality of sliding tracks and attached to an inner side of said different corresponding sliding track, and
- comprising at least one fracture element between at least one of (1a) a first strut and a second strut, (1b) a strut of the plurality of struts and a sliding track of the plurality of sliding tracks;
- and (1c) a strut of the plurality of struts and at least one connector that in electrical contact and in monolithic mechanical contact with at least one of the sliding tracks of the plurality of sliding tracks,
- wherein the first strut corresponding to a first sliding track and the second strut corresponding to a second sliding track are monolithically connected with one another such that said first and second sliding tracks of the plurality of sliding tracks are monolithically interconnected through and with said first and second struts to be held in a fixed spatial relation,
- wherein the monolithic sliding track component includes a metal or an electrically conductive material.
A monolithic sliding track component comprising:
- a plurality of sliding tracks, each shaped as a hollow cylinder having an outer side, an inner side, and a center axis,
- a plurality of struts, each strut of said plurality of struts corresponding to a different sliding track of the plurality of sliding tracks and attached to an inner side of said different corresponding sliding track,
- wherein a first strut corresponding to a first sliding track and a second strut corresponding to a second sliding track are monolithically connected with one another such that said first and second sliding tracks of the plurality of sliding tracks are monolithically interconnected through and with said first and second struts to be held in a fixed spatial relation,
- wherein struts of said plurality of struts form multiple groups of struts, each group of struts containing multiple struts and respectively corresponding to a different sliding track of the plurality of sliding tracks, a first group of struts containing said first strut, a second group of struts containing said second strut,
- wherein each of the first strut and the second strut comprises a respectively-corresponding fracture element at a respectively-corresponding end of each of the first and second strut that is distal to the respectively-corresponding sliding track from the plurality of sliding tracks,
- wherein the monolithic sliding track component includes a metal or an electrically conductive material.
