Electrically insulating cage nut

摘要

An electrically insulating cage nut (10) having a nut body (12) which is held in a cage (14), in which the nut body (12) has a cylindrical attachment (16) and a broadened holding element (18), and the cylindrical attachment (16) has an internal thread (20) and extends through an opening (22) in the cage (14) to the outside, wherein the internal diameter of the opening (22) is substantially larger than the external diameter of the cylindrical attachment (16), but is smaller than the external size of the holding element (18), and an insulator apparatus (24) is arranged between the cage (14) and cylindrical attachment (16), wherein the insulator apparatus (24) is formed integrally, and in consequence the cage nut (10) consists of only three components (12, 14, 24).

主权项

1. Electrically insulating cage nut (10) comprising a nut body (12) which is contained in a cage (14), in which the nut body (12) comprises a cylindrical projection (16) and a widened holding element (18), and the cylindrical projection (16) has an internal thread (20) and extends outwards through an opening (22) in the cage (14), the internal diameter of the opening (22) being considerably larger than the external diameter of the cylindrical projection (16), but smaller than the external dimensions of the holding element (18), and an insulator device (24) being arranged between the cage (14) and the cylindrical projection (16), characterised in that the insulator device (24) is formed in one piece and therefore the cage nut (10) only consists of three components (12, 14, 24); and
the insulator device (24) comprising a hollow cylindrical body (26), by means of which said device is rigidly attached to the cylindrical projection (16) and said body comprising insulating plates (30, 32) extending outwards in a planar manner at the two ends of said body, between said insulating plates the edge (34) of the opening (22) is movably received in the cage (14) at least radially relative to the axis of rotation of the cylindrical projection (16).
