Method and apparatus for lightweight corona device shield mounting

摘要

A lightweight easily installed shield for a corona generating device. A frame to support the end blocks and provide a structural member for a corona generating device is provided. The shield for the corona generating device is made of a lightweight, thin conductive material such as stainless steel and are formed so that they have a generally bowed out cross section prior to installation in the frame. To install the shield in the frame it is squeezed together and inserted in the frame. Once released the resilient bias of the steel causes the shield to be restrained within the frame and can be accurately located and retained by using a locating pin or ridge formed in the frame. The shield described allows easy and accurate assembly of the corona generating device.
