Said convex-concave mechanism comprises and is arranged on the corresponding shrinkage pool/through hole that is provided with at least one fixedly protuberance and the movable contact spring of armature top, fixedly between protuberance and the shrinkage pool/through hole through riveted joint or weld and fix.
Said clasp mechanism is arranged at least one clasp of movable contact spring or armature outer rim, and clasp can fasten the outer rim of armature or movable contact spring.
Said movable contact spring one end is connected with movable palping foot, and the downward bending of an other end is also stretched out pedestal.
The downward bending part of the corresponding movable contact spring of said yoke is provided with the second fixing protuberance, second fixedly between protuberance and the movable contact spring through riveted joint or weld and fix.
Said first fixed touching plate and second fixed touching plate are arranged on the both sides of pedestal; Its lower ends downward is stretched out pedestal, and the upper end of first fixed touching plate is connected with first and decides haptic element, and it is positioned at the below of movable palping foot; First decides haptic element and movable palping foot for often opening; The upper end of second fixed touching plate is connected with second and decides haptic element, and it is positioned at the top of movable palping foot, and second decides haptic element and movable palping foot is normally closed.
Said movable contact spring is a flexure strip.
Said base bottom also is provided with the binding post that is electrically connected with coil.
Through adopting technique scheme, adopt the fixing mode of multiple spot between armature of the present invention and the movable contact spring, make location between the two more accurate; Improve the performance of anti-vibration greatly; Movable contact spring generally adopts copper to form, and also has heat dispersion preferably, can pass through bigger electric current; Coil and yoke are fixed on the pedestal by iron core, can increase its anti-seismic performance equally.Movable contact spring of the present invention hardly can be because of vibrations produce the displacement phenomenon, and the anti seismic efficiency of electromagnetic relay is good, and the electric current that can pass through is big, and simplicity of design is reasonable, and it has vast market prospect, are fit to promoting the use of of enterprise.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Referring to Fig. 1-Fig. 4; The electromagnetic relay of this against shock comprises pedestal 1 and shell 2, is provided with yoke 3, iron core 8, coil 11, armature 4, first fixed touching plate 6, second fixed touching plate 7 and movable contact spring 5 in the cavity that both form; Its iron core 8 vertically passes coil 11 and yoke 3; And be fixed on both on the pedestal 1, even electromagnetic relay shakes, can not cause coil 11 and yoke 3 displacements yet; Armature 4 through convex-concave mechanism with (or) clasp mechanism is fixedly connected on the downside of movable contact spring 5, both unsettled tops that are arranged on iron core 8.
Convex-concave mechanism comprises and is arranged on the corresponding through hole 14 (or shrinkage pool) that is provided with at least one fixedly protuberance 13 and the movable contact spring 5 of armature 4 tops.Wherein, the fixedly protuberance 13 of present embodiment is 3, arranges finished product word shape, fixedly can be fixing through riveted joint or welding between protuberance 13 and the through hole 14 (or shrinkage pool).Clasp mechanism is arranged at least one clasp 15 of movable contact spring 5 or armature 4 outer rims, and clasp 15 can fasten the outer rim of armature 4 or movable contact spring 5, wherein, and totally two of the clasps 15 of present embodiment.As long as convex-concave mechanism and clasp mechanism satisfy the condition that movable contact spring 5 can spacing fixed armature 4, can omit one of them, be 3 like the fixedly protuberance 13 of present embodiment; Arrange finished product word shape; It just satisfies the condition of the spacing fixed armature of movable contact spring, at this moment, can omit clasp mechanism.And for example, movable contact spring three side outer rims are provided with clasp, and clasp fastens armature three side outer rims respectively, satisfy the condition that movable contact spring can spacing fixed armature equally, at this moment, just can omit convex-concave mechanism.This is that those skilled in the art all can understand, and gives unnecessary details no longer one by one.
