It is cumbersome so that assembling of the invention is increasingly complex.Upper magnetic conductive cylinder and projection can be integrally formed, also can be after shaping on lead
A part is cut out on magnetic cylinder to form projection.
Preferably, the projection and yoke plate of the upper magnetic conductive cylinder are by welding or riveting fixation.
Preferably, the curved setting of projection, the raised quantity at least two, projection are set in uniform intervals
Put on described on the upside of magnetic conductive cylinder.
Preferably, formed with the holding tank for accommodating upper magnetic conductive cylinder at the top of the bobbin.
Preferably, the internal diameter of the upper magnetic conductive cylinder is more than the external diameter of the dynamic iron core upper end, above led when dynamic iron core is located at
When in magnetic cylinder, formed with gap between upper magnetic conductive cylinder and dynamic iron core.Above-mentioned setting can avoid dynamic iron core from contacting institute with upper magnetic conductive cylinder
Caused frictional force.
Preferably, the bobbin upper end is formed outwards formed with inwardly projecting internal projecting ring, the dynamic iron core upper end
The outer bulge loop of protrusion, the outer bulge loop are located at the top of the internal projecting ring.
Preferably, the internal diameter of the upper magnetic conductive cylinder is more than the external diameter of the outer bulge loop.
Preferably, the groove runs through the yoke plate up and down, the raised height of the upper magnetic conductive cylinder is more than described recessed
The depth of groove.Above-mentioned setting can make the upper limb of projection be located at yoke plate, the fixed operation being easy between raised and yoke plate.
Preferably, the raised position above yoke plate is riveting at the raised riveting point at riveting point
The riveting block lid formed afterwards overlays on the yoke plate upper surface.At riveting point on the upside of yoke plate, upper magnetic conductive cylinder and yoke can be easy to
Iron plate rivets or the progress of weld job；Riveting block lid overlays on yoke plate upper surface, magnetic conductive cylinder can be avoided to depart from yoke downwards
Plate.
The present invention have can increase magnetic circuit system in the whole stroke that dynamic iron core is moved to dynamic iron core magneticaction power
The advantages of uniformity, can guarantee that movable contact and stationary contact good contact, and relay volume and production cost will not be increased.
