ELECTRICALLY CONDUCTIVE SCREW CONNECTION AND SPECIAL BUSHING FOR A SCREW CONNECTION OF SAID TYPE
First Claim
1. Electrically conductive screw connection between two parts (10, 12) which are screwed to one another by means of a screw (16), having a screw head (18) and a shank (22) with an external thread (24), and by means of a nut (28), wherein the screw (16) runs through a bore (14) in the one part (10), characterised in that the electrical contact between the other part (12) and the screw (16) is produced by teeth (27) on the workpiece-side surface of the screw head (18) and/or of the nut (28) or of a washer (30) arranged between the nut (28) and the other part (12), whereas the contact between the screw (16) and the one part (10) is produced by a bushing (34;

Abstract
An electrically conductive screw connection between two parts (10, 12) which are screwed to one another by means of a screw (16) with a screw head (18) and with a shank (22) with an external thread (24) and by means of a nut (28), wherein the screw (16) runs through a bore (14) in one part (10), wherein the electrical contact between the other part (12) and the screw (16) is produced by teeth (27) on the workpiece-side surface of the screw head (18) and/or of the nut (28) or of a washer (30) arranged between the nut (28) and the other part (12), whereas the contact between the screw (16) and one part (10) is produced by a bushing (34; 34′) which is formed so as to be radially elastic and which is arranged coaxially with respect to the shank (22) of the screw (16) in a portion (15) of the bore (14) with an enlarged inner diameter.
