Magnetic Ballasts for 10-40 Watt Fluorescent Lamps

摘要

The present invention relates to a magnetic ballast for 10-40W fluorescent lamp, the concave groove 103 is formed in the center of the bottom and the coupling groove 101, 102 formed on both sides and the coupling groove (2a) on the surface side Coupling pieces 201 and 202 are formed at both sides to form a coupling plate 2 having a protruding line 203 formed at the center thereof, so that the coupling grooves 101 on both sides of the iron core 1 are formed as shown in FIG. Both side engaging pieces 201 and 202 of the fixing plate 2 are coupled to the 102 so that the iron core is fixed, and the protrusion line 203 is coupled to the inlet of the central concave groove 103 so that the ventilation hole 2b is formed inward. The front wire holder device portion of the fixing plate (2) forms a fusion portion (yay) to drill the hole 205 to be in line with the protrusion line 203 to form a coupler 206 to protrude outward from the inside of the hole Protruding lines 207 and 208 are formed so that fixing grooves are formed at both sides thereof, and the fixing grooves between the protruding lines have a wire hole having a tunnel-type electric wire coupling hole 301. (3) is installed so that the coupling hole 206 is fitted into the coupling hole 302, the upper surface of the projection line 207, 208 has a coupling groove (401, 402) in the lower plate (4b) and the coupling groove in the middle of the lower plate (403) and the upper plate (4a) is configured to mount the upper and lower half-shaped wire holder (4) in which the bolt is screwed, and the protective cover (5) (6) is coated on the coil wire exposed portion, the current loss is small It is possible to obtain a highly efficient fluorescent ballast.
