Abstract
The utility model discloses a separate magnetic controlling switch, which comprises a movable contact, a static contact, a contact draw rod, a driving mechanism and a casing. The utility model is characterized in that the contact draw rod is provided with a magnet or a magnetic induction body which is fixed with the contact draw rod; a magnet (or a magnetic induction body) is fixed on the casing on the opposite side of the driving mechanism; or a magnet is fixed on the casing between the movable contact and the magnet or the magnetic induction body. Because the switch adopts the active force between the magnets, or between the magnet and the magnetic induction body, or among the magnet, the magnetic induction body and an electromagnet, the electromagnet counter force spring of the existing switch is replaced; the mechanical vibration and contact bounce are reduced; so the mechanical abrasion and electrical abrasion of the contact are reduced, as well as the phenomenon of fusion welding of the contact; the service life of the switch can be longer.
Description
The utility model belongs to contact switch, is specifically related to isolated magnetic control switch.
Existing contact switch is of a great variety, but constitutes by contact part and operation part, and existing is that example illustrates its structure with the most representative electromagnetic switch, and it mainly contains moving contact 1, fixed contact 2, contact pull bar 3, reaction spring 4, baffle plate 5, armature 6, electromagnet 7 and shell 8(see accompanying drawing 1).Fixed contact is fixed on the housing, and contact pull bar one end links to each other with moving contact, and the other end is connected with armature, also has reaction spring on the contact pull bar, reaction spring one end contacts with backstop on the contact pull bar, and the other end contacts with baffle plate on the housing, and electromagnet is fixed on housing bottom.When electromagnet gets when electric, the armature adhesive moves downward moving contact by the contact pull bar, contact closure, simultaneously, the reaction spring compressed energy-storage.When the electromagnet dead electricity, electromagnet suction disappears, and under the reaction spring effect, armature discharges, and by the contact pull bar moving contact is moved upward, and contact separately.Because this switch adopts electromagnet and the operation of reaction spring mechanism, so cause switch vibration and contact bounce in the course of the work, mechanical breakdown both having taken place easily, increased the weight of contact mechanical wear and electrical wear again, even had made contact melting welding, influence the dynamo-electric life-span of switch, simultaneously, the switching mechanism complexity, functional reliability is poor, big energy-consuming, volume and weight is big.
The purpose of this utility model provides the isolated magnetic control switch of a kind of contact stabilization, reliable operation, simple in structure, small-sized light weight, energy-saving safe.
For achieving the above object, the utility model isolated magnetic control switch has moving contact, fixed contact, contact pull bar, driving mechanism and housing, its contact pull bar is fixed with permanent magnet or magnetic induction body, and driving mechanism is fixed on housing bottom, is fixed with permanent magnet on the housing of driving mechanism offside.
Or contact pull bar one end is connected with moving contact, and the other end is fixed with permanent magnet or magnetic induction body, is fixed with permanent magnet on the housing between permanent magnet or magnetic induction body and the moving contact, and driving mechanism is fixed on housing bottom;
Or being fixed with permanent magnet on the contact pull bar, driving mechanism is fixed on housing bottom, is fixed with permanent magnet or magnetic induction body on the housing of driving mechanism offside;
Or contact pull bar one end is connected with moving contact, and the other end is fixed with permanent magnet, is fixed with permanent magnet or magnetic induction body on the housing between permanent magnet and the contact, and driving mechanism is fixed on housing bottom.
Isolated magnetic control switch, its contact partly has radome, and radome and housing are fixed.
Isolated magnetic control switch, its driving mechanism can also be fixed on the housing outer bottom.
Isolated magnetic control switch, its driving mechanism are permanent magnet, and permanent magnet slides by its handle and is fixed in the gathering sill of fixing with the housing outer bottom.
Isolated magnetic control switch also is connected with the operation electromagnet on the handle of its permanent magnet, the operation electromagnet cooperated by having contact with release on it.
Isolated magnetic control switch, have contact with in addition on its permanent magnet, have contact be fixed on housing on release cooperate.
Isolated magnetic control switch, its driving mechanism are permanent magnet, and permanent magnet slide be fixed on the fixing box body of outside in, permanent magnet has the push rod by cap to be connected with an end, by between cap and the box body back-moving spring being arranged.
Isolated magnetic control switch of the present utility model has adopted said structure, the electromagnet and the reaction spring mechanism of existing electromagnetic switch have been cancelled, combine with electromagnetism by permanent magnetism power or permanent magnetism and to realize contact deciliter, improved switch performances: because the magnetic padlock effect, can significantly alleviate the spring of contact, improve the electric life of switch; Owing to there is not reaction spring, there is not impingement phenomenon unshakable in one's determination and armature yet, can alleviate mechanical oscillation, improve the mechanical endurance of switch; Because permanent magnet system is realized Memorability work easily, can realize the energy-saving silencing operation of electrical system; Because switch operating mechanism is simple, is convenient to realize miniaturization, the lightweight of switching device, can reduce mechanical breakdown simultaneously.
