发明名称 Device for demagnetizing a picture tube.
摘要 <p>The device comprises a demagnetization coil (1) wound from electrically conducting insulated wire (5) and surrounded by an electrically insulating sheath (7). A connection member (17) is connected to the two ends of the wire (5). The connections (19) between the connection member (17) and the wire (5) are surrounded by an electrically insulating envelope constituted by a sheet (21) of electrically insulating foil, which is folded so that the connections (19) and the adjoining parts of the sheath (7) are disposed between the facing parts of the sheet (21). The edges of the sheet (21) conducting each other are connected to each other by means of a welding connection (23). The sheet is further connected by means of a welding connection (23) to the sheath (7) and to an envelope of the connection member (17). The sheet 21 constitutes an envelope for the connections (19), which is tight but for one lead-through opening for the connection member (17). &lt;IMAGE&gt;</p>
