Abstract
The utility model discloses a selective switch with a magnetic arc-extinguishing device, comprising an upper cover, a lower cover and at least one switch box positioned between the upper cover and the lower cover, wherein the upper cover, the at least one switch box and the lower box are stacked from top to bottom, each switch box comprises a box body part and a plurality of pairs of contacts arranged on the box body part, and each pair of contacts comprises a movable contact and a stationary contact and is characterized in that magnetic sheets are respectively arranged on the upper and the lower sides of each pair of contacts, the direction of magnetic poles of the magnetic sheets is vertical to the moving direction of the movable contact of the pair of contacts, the magnetic sheets arranged on the upper sides of the pair of contacts and the magnetic sheets arranged on the lower sides of the pair of contacts are arranged in opposite, and the polarity arrangement directions are the same. The selective switch with the magnetic arc- extinguishing device can play the role of arc absorption when the contacts are disconnected, so that the contacts can be protected from being burnt out.
Description
Technical field
The utility model relates to electric switch.
Background technology
Along with industrial expansion, in the operation of electric equipment, increasingly high for fail safe, the reliability requirement of switch.The internal structure of existing selector switch please refer to Fig. 4 and Fig. 5, and it comprises loam cake, lower cover (loam cake and lower cover are not shown) and at least one switch enclosure 8 between loam cake and lower cover.The situation of three switch enclosures has been shown among the figure, and loam cake, these three switch enclosures 8 and lower cover pile up from top to bottom.Each switch enclosure 8 includes box body portion 81 and is arranged on some to contact in the box body portion 81, and every pair of contact comprises a moving contact 83 and a fixed contact 85.Because in the box body portion 81 arc-control device is not set, the switch that has has spark phenomenon, causes poor contact of contacts, serious meeting burns out the contact, and switch damages, and the equipment that makes can't normally move.
Summary of the invention
The utility model technical problem to be solved is to provide a kind of selector switch of carrying magnetic arc-control device, and it has the arc of suction function when breaking off in the contact.
The technical scheme that the utility model adopted is: a kind of selector switch of carrying magnetic arc-control device; Comprise loam cake, lower cover and at least one switch enclosure between loam cake and lower cover; Said loam cake, at least one switch enclosure and lower cover pile up from top to bottom; Each switch enclosure comprises box body portion and is arranged on some to contact in this box body portion that every pair of contact comprises a moving contact and a fixed contact, is characterized in; Each upper and lower both sides to contact is respectively equipped with magnetic sheet; The pole orientation of this magnetic sheet is perpendicular to this direction of motion to the moving contact of contact, and the magnetic sheet of the magnetic sheet of this a pair of contact upside and this a pair of contact downside is oppositely arranged, and the polarity orientation is identical.
Above-mentioned selector switch, wherein, the box body portion of each switch enclosure be positioned at every pair of contact in this switch enclosure box body portion above be provided with magnetic sheet; Said lower cover is being provided with magnetic sheet with the corresponding position of the magnetic sheet of bottom switch enclosure.
Above-mentioned selector switch, wherein, the quantity of said switch enclosure is three.
After adopting technique scheme, when the rotary switc turn-off current, the moving contact of contact separates with fixed contact, causes arcing.Owing to the polarity orientation of the magnetic sheet that is positioned at contact upside and downside is identical, play and inhale the arc effect, can prevent that the contact from being burnt out, thereby improve the fail safe and the reliability of switch.

Embodiment
Below in conjunction with accompanying drawing the utility model is made and to be further specified.
With reference to figure 1 and Fig. 2.The selector switch of the utility model; Comprise loam cake 1, lower cover 3 and at least one switch enclosure 2 between loam cake and lower cover; Loam cake 1, at least one switch enclosure 2 and lower cover 3 pile up from top to bottom; Each switch enclosure 2 comprises box body portion 21 and is arranged on some to contact in this box body portion that every pair of contact comprises a moving contact 23 and a fixed contact 25.Only show the situation of three switch enclosures among the figure, yet the quantity of switch enclosure can change according to the needs that reality is used.
In conjunction with shown in Figure 3.In the utility model, each upper and lower both sides to contact is respectively equipped with magnetic sheet 4, and the pole orientation of magnetic sheet 4 is perpendicular to this direction of motion to the moving contact 23 of contact.And the magnetic sheet 4 of this a pair of contact upside and the magnetic sheet 4 of this a pair of contact downside are oppositely arranged, and the polarity orientation is identical.In Fig. 3, the direction of motion of moving contact 23 is horizontal direction, and the pole orientation of magnetic sheet 4 is a vertical direction.The polarity orientation that is positioned at the magnetic sheet 4 of contact top is the N utmost point down, and the S utmost point is last, and is same, and the polarity orientation that is positioned at the magnetic sheet 4 of contact below also is the N utmost point down, and the S utmost point is last.A pair of fixed contact 25 is arranged on the contact bridge 27.
In a kind of preferred embodiments, the box body portion 21 of each switch enclosure be positioned at every pair of contact in this switch enclosure box body portion 21 above be provided with magnetic sheet, lower cover 3 is being provided with magnetic sheet with the corresponding position of the magnetic sheet of bottom switch enclosure.Because loam cake, switch enclosure and lower cover are stacked, the magnetic sheet 4 in each layer switch enclosure also becomes the magnetic sheet of the contact downside of last layer switch enclosure, thereby the upper and lower both sides that formed every pair of contact are provided with the layout of magnetic sheet.The magnetic sheet of the contact downside of basecoat switch enclosure then is arranged in the adjacent with it lower cover 3.
When the rotary switc turn-off current, the moving contact 23 and the fixed contact of contact were opened in 25 minutes, caused arcing.Owing to the polarity orientation of the magnetic sheet that is positioned at contact upside and downside is identical, play and inhale the arc effect, can prevent that the contact from being burnt out, thereby improve the fail safe and the reliability of switch.
The description of this embodiment has combined certain embodiments, but it should be understood by one skilled in the art that the utility model is not limited to embodiment described here, and can carry out various modifications and variation and do not deviate from the spirit and the scope of the utility model.
