Abstract
An isolated moving contact group comprises an installation base, a plurality of movable contacts, a plurality of compression springs and a plurality of hoops, wherein multiple groups of oval upper opening holes and multiple groups of oval lower opening holes are arranged at the front side and the rear side of the installation base at equal intervals, a large arc groove is vertically arranged at each opening hole, a small arc groove near to the large arc groove directly reaches the bottom edge of the base, the compression springs and first moving contacts are arranged in the upper opening holes, second moving contacts are arranged in the lower opening holes, the compression springs, the first moving contacts and the second moving contacts are sequentially clamped in the hoops, and the hoops are clamped in the small arc grooves of the installation base. In the moving contact group, the cylindrical moving contacts are adopted, the moving contacts enter static contacts in a rolling insertion way during use, the moving contacts and the static contacts are in line contact, thus, the contact area of the moving contacts and the static contacts is expanded, the contact resistance is reduced, the conductivity of a switch is improved, and the service life of the switch is prolonged; and since the hoops are adopted and clamped in the grooves at the two sides and grooves of the second moving contacts, the moving contact group is stable in working performance and simple in structure, and is easy to manufacture and assemble.
Description
Technical field
The present invention relates to a kind of electric elements, particularly relate 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 object of the invention is to the many disadvantages overcoming existing diverter switch moving contact group, disclose a kind of moving contact group of stable performance.
The technical solution used in the present invention 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.
