Abstract
The utility model relates to an operating mechanism for permanent-magnet switches, which comprises a casing and an end cover, wherein, a transmission shaft which is arranged in the casing and passes through the end cover is installed on a permanent magnet arranged on the transmission shaft; the outside surround of the permanent magnet is provided with a pulsed coil and an iron core arranged in the pulsed coil. The utility model has the advantages of convenient operation, simple structure, low noise, action flexibility and reliability, and light weight.
Description
The utility model belongs to a kind of permanent magnet switch operating mechanism, is applicable to electric power vacuum switch, hydraulic selector.
Being used for electric power vacuum switch, hydraulic selector at present all is to be finished by mechanically actuated operation, mainly has following shortcoming with the mechanically actuated operation switch: the one, and the noise that mechanical heaviness is brought is big, operating sensitivity is poor, weight is big; The 2nd, operation inconvenience, complex structure, be prone to fault, life-span and lack.
The utility model purpose provides that a kind of noise is little, permanent magnet switch operating mechanism reliable, that the life-span is long is active in one's movements.
The utility model includes housing, end cap is equipped with at two ends at housing, it is characterized in that in housing, being provided with and pass the overhanging power transmission shaft of two end cap and two ends, on power transmission shaft, be fixed with permanent magnet, permanent magnet is set with the iron core that is fixed on the housing inner headed face outward, and the two ends of iron core respectively are tied with a pulsed coil.
The bistable state that the utility model adopts pulsed coil realizes course of action by pulse signal, need not locking and linkage, has replaced traditional mechanically actuated operation, thus simple in structure, in light weight, noise is little, be active in one's movements reliable, the life-span is long.
Accompanying drawing shows embodiment of the present utility model, wherein:
Fig. 1 is an overall diagram of the present utility model;
Fig. 2 is a profile of the present utility model.
As seen from the figure, the utility model includes housing (5), at the two ends of housing (5) end cap (2) is arranged, housing (5) is to be connected by bolt with end cap (2), housing (5) is manufactured with metal material with end cap (2), in housing (5), be provided with the copper sheathing (3) that passes on the two end cap (2), and the power transmission shaft (4) that two ends are overhanging, be fixed with permanent magnet (8) on the power transmission shaft (4), permanent magnet (8) is outer to be set with the iron core (7) that is fixed on housing (5) inner headed face, and the two ends of iron core (7) respectively are tied with a pulsed coil (6).
The course of work of the present utility model: when applying a pulse current for pulsed coil (6), coil just produces magnetic force, act on the permanent magnet (8), permanent magnet (8) is moved to the other end by an end, according to the bistable state principle, permanent magnet (8) is crossed the center, just reaches another stable state fast, and utilizes permanent magnet (8) self suction to keep stable.When needs permanent magnet (8) during to the motion of another direction, only need add a reverse impulse electric current, permanent magnet (8) just repeats said process, arrives another stable state, drives the open and close work of switch.
Claims (1)
1, a kind of permanent magnet switch operating mechanism, include housing (5), at the two ends of housing (5) end cap (2) is housed, it is characterized in that in housing (5), being provided with and pass two end cap (2), and the power transmission shaft (4) that two ends are overhanging, be fixed with permanent magnet (8) on power transmission shaft (4), permanent magnet (8) is outer to be set with the iron core (7) that is fixed on housing (5) inner headed face, and the two ends of iron core (7) respectively are tied with a pulsed coil (6).
