ABSTRACT:
A deflection yoke has a tight coupler is provided. On periphery of a neck holder of the deflection yoke of a cathode ray tube, tapered threads are formed on threaded members on which a locking nut can be throttled. Peripheral slots are provided around the threads to enable compression of the threads. As a locking nut is screwed on the tapered threads, the threads compress and tighten around the neck of the cathode ray tube, firmly securing the deflection yoke to the periphery of the neck of the cathode ray tube. Protrusions on one end of the threads act as a stop for the locking nut and also hold a magnetic ring in place on the CRT.
