Abstract
A support and tensioning device for an elongated corona generating electrode includes a corona charger shield member that includes a first set of wall members for serving as a shield for a corona generating electrode. The shield member includes a second set of wall members shaped to define a recess formed at one end of the shield member for receiving therein a plunger member and a spring. The recess includes an inner positioned land for engaging a head end of the spring. The second set of wall members define the recess and include walls located to define a key slot opening which extends in a longitudinal direction of the shield member. A spring resides in the recess and engages the land to restrict movement of the spring within the recess. A hollow plunger member has a generally cylindrical sidewall for supporting the plunger for rotational movement in the recess and a land on or near a head end portion of the plunger member engages a tail end of the spring. The plunger member includes a wall having a slug receiving opening for receiving a slug formed on one end of the corona electrode and a slot extends from the slug receiving opening in the wall towards the head end portion of the plunger member. A key extends radially from the generally cylindrical sidewall and is located within the key slot opening for sliding movement therein to permit tensioning of the corona electrode. The recess receives the plunger member to permit rotation of the plunger member about the axis of rotation of the generally cylindrical wall to locate the key in the key slot opening to lock the plunger member into the corona charger shield member.
