Abstract
A deflection yoke liner for mounting deflection coils on a cathode ray tube; the liner has at least two interconnectable sections with interengaging snap fasteners in the form of a tab and block that position and fix together the liner sections. The tab has a stop or hook adjacent a distal end for clasping over the block. The block has an inlet groove for guiding the tab and thereby positioning the liner sections relative to one another. One of the groove and tab tapers inwardly and the other is complementary and tapers outwardly. Preferably the tapering sections of the groove and tab engage near a point of full abutment of the liner sections, by way of tapered shoulders at the proximal end of the tab and a narrowing inlet taper on the block. The liner sections are positively positioned as the tab is advanced in the groove until the hook snaps over the abutment upon bringing together the liner sections. The block can be discrete or formed by a continuous ridge. The block and the tab protrude axially above a surface of the flange, the tab width being oriented along a flange of the respective liner section. This mechanism gives an accurate and quick positioning of the supporting liner parts and finds use in deflection yokes for cathode ray tube displays.
