Abstract
A coupler system (13) for mounting a projection lens (15) to a cathode ray tube (16) in a projection television (10) is provided. The system includes a first member (20) composed of a heat and chemical resistant plastic and a second member (22) composed of metal. The second member (22) is mounted to the periphery (18) of the faceplate (17) of the cathode ray tube (16) to provide a high level of heat transfer from the tube. The second member also absorbs x-rays emitted by the tube. The first member can be readily molded from high performance plastic resins and thus reduces the overall cost of the coupler system compared to couplers composed entirely of metal.
