Abstract

An improved stabilizing device incorporated into a socket-adapter for miniature fluorescent lamps includes a square-shaped iron core member with a coil arrangement provided therearound so as to form a required stabilizing device with a square open section defined in a middle portion for accommodating a socket seat of the socket-adapter for known miniature fluorescent lamps. The iron core member is composed of a plurality of L-shaped silicon steel laminated cores, and the coil arrangement includes a plurality of coils wound around a plurality of I-shaped coil frames, each of which has a through opening in a middle portion for being sleevingly installed around both arms of the L-shaped laminated cores so as to form a square open section in the middle of the iron core for accommodating the socket seat of the socket-adapter. Thereby, the total volume of the socket-adapter stabilizing device is substantially decreased.

Dependent claims

A stablizing device, for being incorporated into a socket-adapter for miniature fluorescent lamps comprising:

core means formed with plurality of L-shaped laminated cores for being assembled in a square configuration:
and coil means formed with a plurality of core frames respectively wound with coils and sleevingly disposed around said L-shaped laminated cores so as to form a square-shaped structure with an open section defined in a middle portion thereof for accommodating a socket seat of the socket adapter in the open section:
wherein each of said L-shaped laminated cores includes a straight end and an inclined end so that when said laminated cores are combined together, a stabilizing device is formed having a square open section in a middle portion and an annular circumference on an outer periphery thereof:
wherein each of said coil frames is formed in a l-shape with a through opening provided in a central portion thereof to receive said straight end and said and inclined end of said L-shaped laminated cores so as to effect said core means;
wherein at least one of said coil means is mounted on each side of said square configuration of said core means.
