Embodiment
Below in conjunction with accompanying drawing, just the present invention is above-mentioned is described further with other technical characterictic and advantage.
See also Fig. 1-Fig. 4, the present invention comprises armature a1 at concrete structure, permanent magnet a2, a3, and interior yoke a4, outer yoke a5, coil a6, coil rack a7, connecting rod a8 etc., armature a1 wherein, interior yoke a4, outer yoke a5 material properties is high permeability material.
Permanent magnet a2 is the magnetic shoe structure, magnetizing direction is radial magnetizing, and interior yoke a4 contacts with a face on permanent magnet a2, the a3 magnetizing direction, and outer yoke a5 contacts with another face on permanent magnet a2, the a3 magnetizing direction, at armature a1 both as touching parts, also as the iron core of coil 6.
Among the present invention, armature a1 lateral cross section is circular, and the longitudinal cross-section is designed to I-shaped; The position of permanent magnetism a2, a3 can be designed to multiple arrangement mode as required, and the selection of permanent magnet also can change various material such as neodymium iron boron, aluminium nickel cobalt, ferrite into according to designing requirement, and it provides the confining force effect of end for armature; The longitudinal cross-section structural design of interior yoke a4 is to C shape, central shaft with whole magnetic circuit is symmetry axis, be convenient to processing, symmetrical configuration has also reduced the difficulty of assembling simultaneously, when armature a1 is in upper end position, armature a1 contacts with the lower surface that interior yoke a4 goes to the bottom, and when armature a1 was in lower end position, armature a1 contacted with the upper surface of interior yoke a4 upper base; The longitudinal cross-section structural design of outer yoke a5 is to C shape, central shaft with whole magnetic circuit is symmetry axis, and when armature a1 was in upper end position, armature a1 contacted with the lower surface of outer yoke a5 upper base, when armature a1 was in lower end position, armature a1 contacted with the upper surface that outer yoke a5 goes to the bottom; Coil a6 is wrapped on the coil rack a7 of interior yoke a4 inside; Connecting rod a8 and armature a1 relative position are fixed, and the end can connect main contacts, when armature a1 moves, realize the switching of signal.
