Abstract
A device for simply and precisely fixing a deflection yoke to a Braun tube in such a manner that it does not permanently affix the yoke to the Braun tube but permits the location and fixing angle of the yoke with respect to the Braun tube be easily changed as required. The device includes a holder, coupled to a separator, and a plurality of wedge type cams rotatably mounted on the holder. The holder is provided with a plurality of mounts for rotatably supporting the wedge type cams respectively, a plurality of releasable fixing members for fixing the cams at their adjusted angles, and connection bands extending between the mounts for connecting the mounts together. The wedge type cams not only adjust the yoke fixing angle for compensation of mis-alignment of electron gun but also releasably affix the deflection yoke to the Braun tube. In another embodiment, the wedge type cams may be substituted by pulley type cams which are rotatably mounted on the holder.
