摘要

A coil older (13) incorporating a recess (21) for the winding (17) is formed integrally with two closure flaps (23a,23b) pivoted (22) about its ends. The annular winding (17) is placed on four pins (16) within the holder (13), and the flaps (23a,23b) are closed and secured by means of catches (20a,20b) entering into notches (24a,24b) in their ends (25a,25b). The pins (16) are formed on the floor (14) of the coil holder within the recess (21), and in the closed position protrude through holes (27) in the flaps (23a,23b). USE/ADVANTAGE - Against health hazards from TV receiver and VDU tube deflection systems, parts count and prodn. costs are reduced.
