Abstract
The utility model provides an isolated form moving contact group, includes the mounting base, and is many to the moving contact, many compression spring, and a plurality of staple bolts, trompil and trompil down on two side equidistance are provided with the multiunit oval -shaped around the mounting base trompil department is provided with through base of the little recess of one circular arc on one big recess of circular arc next door perpendicularly, is provided with compression spring and first moving contact in last trompil, is provided with the second moving contact under in the trompil, compression spring, first moving contact, the second moving contact blocks in proper order to be put in the staple bolt, and the circular arc dell inslot at the mounting base is established to the staple bolt card, this moving contact group is owing to adopted the cylinder moving contact, its moving contact inserts as the roll when getting into the static contact in using, and move, the static contact is the line contact, make and move, the area of contact increase of static contact, contact resistance reduces, the service life of change over switch's electric conductive property with is prolonged, because it puts in the recess of the recess of two sides and second moving contact to have adopted staple bolt and staple bolt card, stable and the simple structure of working property who makes the moving contact organize, easily make and the assembly.
Description
Technical field
The utility model relates to a kind of electric elements, particularly relates to a kind of isolated form moving contact group.
Background technology
Isolating switch is a kind of conventional low-voltage electrical apparatus, and its key element is moving contact group.Traditional moving contact group adopts bridge-type list contact usually, be improved to the two contact of bridge-type afterwards, now column type moving contact group is also had to occur, the employing helical spring that spring-compressed mechanism in moving contact group has, some employing arch bridge-type springs, bridge-type moving contact group generally adopts copper sheet, it is point cantact when contacting with fixed contact, its electric conductivity and heat dispersion very poor, described arch bridge-type spring is owing to requiring very high to materials and process, difficult quality guarantee, due to the appearance of these defects, has had a strong impact on the serviceability of diverter switch.
Summary of the invention
The purpose of this utility model is the many disadvantages overcoming existing diverter switch moving contact group, discloses a kind of moving contact group of stable performance.
The technical solution adopted in the utility model is: a kind of isolated form moving contact group, comprise mounting base, multipair moving contact, many Compress Springs, multiple anchor ear, described mounting base is equidistantly provided with along side, front and back two and organizes perforate more, described perforate is made up of the upper perforate of ellipse and lower perforate, one circular arc big groove is vertically installed with at described tapping, two sides of adjacent described circular arc big groove are provided with one little groove of circular arc, two described road grooves go directly pedestal base, the top of perforate is provided with Compress Spring on described, the bottom of perforate is provided with the first moving contact on described, the second moving contact is provided with in described lower perforate, described Compress Spring, first moving contact, second moving contact successively holding in described anchor ear, and described anchor ear holding is in the little groove of the circular arc of mounting base.
Further setting, described anchor ear is rectangle, and centre is set to opening, described opening is made up of upper shed, split shed and under shed, and described upper shed is set to square, and top is provided with a convex edge, bottom is set to step, and described split shed and under shed are the circular arc of indent.
Further setting, the first described moving contact and the second moving contact are set to cylinder, the radius of described cylinder two end is larger, the radius of interlude is less, and the arc radius of interlude cylinder radius and described anchor ear under shed coincide mutually, two ends of described first moving contact and the second moving contact extend to mounting base outside, and anchor ear holding place of described second moving contact is provided with two road grooves, and the holding for anchor ear is stablized.
The beneficial effect that the isolated form moving contact group of above structure has is: owing to have employed cylinder moving contact, insert for rolling when in use its moving contact enters fixed contact, the contact position of moving contact and fixed contact is linear contact lay simultaneously, make to move, the contact area of fixed contact increases, contact resistance reduces, substantially increase electric conductivity and the useful life of diverter switch, simultaneously owing to have employed anchor ear and being set in the Compress Spring in anchor ear, and in the groove of the groove of anchor ear holding in two sides and the second moving contact, make the working stability of moving contact group and structure is simple, be easy to manufacture and assembling.
