Claim 12
Dependent Claim
33 words
A device according to claim 1 the element (1) includes a mounting piece connected thereto and the means (12) comprises a ring having a central opening (11) therein for receiving the mounting piece.
Claim 13
Independent Claim
334 words
A device for grounded securing of an element (1) at a hole (9) in a metal plate (10) comprising: members (6, 13) movable on both sides of the plate towards each other and the plate for securing the element to the plate; means (12) adapted to establish an electrical connection between the metal plate and the element, said means (12) being arranged to enter into radial abutment on the circumferential wall (27) of the hole while establishing said electrical connection, said means (12) comprising at least one flange portion (20) arranged to be displaced radially within said hole (9) into abutment on the circumferential wall (27) of the hole; said means (12) is adapted, upon moving the securing members (6, 13) towards each other, to be urged by at least one (13) of said members in the axial direction of the hole (9) and thus cause radial displacement of one of said flange portion (20) of the means (12) located in the hole; said means (12) comprising a portion (18) being conical in an unloaded state and adapted to be arranged coaxially with respect to the hole (9) of the plate (10), the concical portion (18) is provided with a central opening (11) at the tip thereof and converges from the hole of the plate towards said one securing member (13); the at least one flange portion including a substantially axial first flange portion (20) integral with the conical portion and projecting into the hole of the plate and a second flange portion (21) facing the plate adjacent said hole, and that the means is arranged, upon moving said one securing member (13) towards the plate, by bearing against the conical portion (18) adjacent the central opening (11), to press said second portion (21) into abutment upon the plate (10) and by continued pressing causing the first flange (20) to be displaced radially in the hole and into abutment upon the circumferential wall (27) thereof by at least partially flattening the conical portion (18).
