Patent ID: 7811429

Claim:
Target support assembly (I), comprising a cylindrical support sleeve ( 2 ) on which is arranged a target lining formed by a cylindrical target sleeve ( 4 ) that is slidingly arranged on the support sleeve ( 2 ), wherein a plurality of elastically-active clamping elements ( 6 ) being distributed between the facing circumferences of said sleeves are each arranged in a respective recess ( 8 ) of a plurality of recesses formed in the external cylindrical surface of the support sleeve ( 2 ), each said clamping element ( 6 ) having a portion ( 6 a ) press-fitted in the therewith associated recess ( 8 ) and possessing a radially projecting portion ( 6 a, b, c ) in clamping contact with the internal cylindrical surface of the target sleeve ( 4 ) that is located opposite said clamping elements ( 6 ); the clamping elements ( 6 ) each comprising an elastically deformable and/or elastically compressible electrically and thermally conductive material; each of said clamping elements ( 6 ) being constituted of an angled leaf spring having the portion ( 6 c ) forming a base arm ( 6 d ) extending along the bottom of the therewith associated recess ( 8 ) and wherein the base arm ( 6 e ) has opposite ends wedged between the side walls of the recess ( 8 ) and a clamping arm ( 6 a ) of said clamping element extending radially angled outwardly from said recess ( 8 ), said clamping arm ( 6 a ) having a free end forming an outwardly curvilinear portion ( 6 b, c ) for clampingly contacting the oppositely located surface of the target sleeve ( 4 ); and wherein the clamping elements ( 6 ) have selectively rounded or oblique insertion edges ( 6 b , 6 c ) on both sides facing in an axial direction.
