Abstract

A support device for a deflection unit (10) for a picture tube comprises pins (17) which in a longitudinal direction carry a thread (19) over part of their circumferences.
The pins run in guide bores, which are constructed so as to exhibit a recess of not less than the angular circumference of the thread. Each pin is at first so aligned in relation to the associated guide bore that the thread runs in the above-mentioned recess. In this position (after the deflection unit has been aligned), each pin is pushed until it contacts the tube cone (18.K). Then each pin is turned by 90°, thus ensuring that the above-mentioned thread cuts into the non-recessed wall of the guide bore. This ensures that each pin is fixed in position, and simultaneously, due to the lead of the thread, a tension is set between deflection unit and tube. The support device thus constructed has the advantage that the tension force between deflection unit and tube cone can be set precisely.
This avoids the optimum setting be lost due to different tension forces acting at the locations of the different support elements, as was the case when conventional support elements were used.
