Summary of the invention
The technical problem that the utility model will solve will provide a kind of convenient installation exactly; And the roughness to piece surface is less demanding; Movable contact spring assembly contact contacts effective electromagnetic relay with the static contact contact, and the technical scheme that solves the problems of the technologies described above is achieved in that electromagnetic relay, and its structure comprises housing, electromagnet coils assembly, magnet steel assembly, movable contact spring assembly, static contact, slide, stator; Has draw-in groove on the housing; Said parts are arranged on enclosure interior, also comprise raised line, and raised line is arranged in the draw-in groove.
Through employing these parts of raised line are set, the contact-making surface that makes raised line and movable contact spring assembly is that line contacts, and can reduce the contact area of movable contact spring assembly and draw-in groove, can reduce the frictional resistance when the movable contact spring assembly is installed, and guarantees the product structure accuracy.
Further the cross section of raised line is semicircle, and the Width along the movable contact spring assembly in draw-in groove extends, and becomes the rail mounted close-fitting.
Further raised line is positioned at the same side of movable contact spring assembly contact.
Adopt such structure, raised line Width along the movable contact spring assembly in draw-in groove extends, and raised line can be arranged at the both sides of movable contact spring assembly; Also can be arranged at a side of movable contact spring assembly, preferably this raised line is positioned at the same side of movable contact spring assembly contact, wherein; The movable contact spring assembly is with draw-in groove, and raised line and movable contact spring assembly cooperate with the mode of rail mounted close-fitting, adopts rail mounted close-fitting mode quality of fit high; Simple in structure, be easy to install.
Further said magnet steel assembly is fixed on the stator with fixed axis, and the cross section of said magnet steel assembly fixed axis is circular; On stator, be provided with the fixing hole that is complementary with this magnet steel assembly fixed axis, said fixing hole is a square hole, and the length of side of fixing hole is greater than the diameter of fixed axis.
Through the fit system of this structure, can reduce the contact area between stator and the magnet steel assembly fixed axis, to realize reducing the pivoting friction resistance of magnet steel assembly fixed axis.
Further said magnet steel assembly core is a rubidium iron boron magnet steel, has permanent magnetic, and remainder is the pure iron material; Making magnetic sheet motion spacing is 2.05mm; To guarantee that moving contact breaks off spacing >=1mm, withstand voltage more than 3500V when guaranteeing to break off, the pressure stroke degree of depth >=0.6mm during connection; Avoiding the generation of relay loose contact, and increased the motion radian of the contact of movable contact spring assembly.
Further the contact on the movable contact spring assembly is an alloy silver composite contact, and the contact on the static contact is the fine silver composite contact.
Because alloy silver composite contact is harder, the fine silver composite contact is softer, adopts such structure, can increase contact-making surface, reduces resistance value, reduces carbon distribution, realizes more high-power.
After assembling, through movable contact spring assembly, static contact and electromagnet coils assembly are carried out sealing, make the overall fixed of movable contact spring assembly, static contact and electromagnet coils assembly be guaranteed, can't at high temperature be out of shape.Movable contact spring assembly, static contact and electromagnet coils assembly stationarity and precision have been strengthened.
