SELF-TENSIONING CORONODE STRUCTURE (Cont'd)

Stringing the wire coronodes for corona generating devices into position between the insulating end blocks has heretofore required a degree of expertise outside the ability of most machine users. The primary difficulty in the procedure is to obtain the a propriate tension on the wire. If the tension is

uniformity. If the tension is too high, breakage of the coronode may result. It would be highly desirable to have a corona charging device with a coronode allowing stringing in a simple manner so that a moderately trained user, rather than a service representative could change or replace the coronode.

Corona charging device 10 is enerally provided with first and second end blocks 12 and 14, a shield inch

First end block 12 generally includes a main body 24 and a cover 26 hingedly mounted with main body 24. Main body 24 supports an electrical connector 30 suitable for connection to a high voltage power source driving coronode 20 to a corona producing condition, and a coronode wire guide 32 around which the double length coronode 20 will be looped and supported at the first end block. Main body 24 forms a partial enclosure around coronode wire guide 32, having walls 34, 36 and 38 extending upwardly from a base portion 40 on which coronode wire guide 32 is supported. An opening in the enclosure is provided along the side of end block 12 opposing second end block 14, through which coronode 20 extends to coronode wire guide 32. Coronode wise guide 32 is formed from a conductive metal material having a spring constant associated with it. The portion of the coronode wire guide 30 which is bent back on itself is formed at an angle which normally allows a portion of the guide to extend somewhat above walls 34,36 and 38, ta allow the coronode to be easily looped around the coronode wire guide 32, and is compressible into the enclosure with the closure of cover 26 after receiving coronode 20 thereabout. Cover 26 is provided with an extension wall 56 which extends downwardly from the cover to substantially complete the partial enclosure of the main body 24 around the coronode wire guide 32 as the cover is closed.

Second end block 14 is provided with a coronode tensioning arrangement for easily anchoring the coronode 20 and exerting the proper tension thereon. Second end block 14 includes main body 60 and cover 62, operating as a tensioning member, hingedly mounted to main body 60 for pivotal movement between open and closed positions. Cover 62 supports a pair of coronode connector anchors 68 in the form of generally C-shaped hooks. Anchors 68 are supported on an exten...
