The two ends of described elasticity transition section are not on a bellows radial section, and two elasticity transition sections at bellows body two ends and the link of welding section deviate from mutually at bellows axis direction.
Described syndeton shape on the cross section crossing bellows axis is "the" shape structure, "the" shape structure has first, second parallel edges and connects the inclined side of first, second parallel edges, first parallel edges and inclined side form elasticity transition section jointly, and the first parallel edges is connected with the end of first bending of bellows body one end.
Two angles between the inclined side of described elasticity transition section and first, second parallel edges are obtuse angle.
The vacuum interrupter that the utility model provides adopts following technical scheme:
Vacuum interrupter, comprise moving conductive rod and bellows, the syndeton for welding with corresponding connector that bellows two ends are respectively equipped with, on the cross section crossing bellows axis, described syndeton comprises welding section and elasticity transition section, described welding section is with bellows axes normal and for welding with corresponding connector, the two ends of described elasticity transition section are respectively with the corresponding end of welding section with the end of bellows body end first bending is corresponding connects, and described elasticity transition section is used for the stress when bellows uses suffered by first bending of reduction corrugated tube end.
The two ends of described elasticity transition section are not on a bellows radial section, and two elasticity transition sections at bellows body two ends and the link of welding section deviate from mutually at bellows axis direction.
Described syndeton shape on the cross section crossing bellows axis is "the" shape structure, "the" shape structure has first, second parallel edges and connects the inclined side of first, second parallel edges, first parallel edges and inclined side form elasticity transition section jointly, and the first parallel edges is connected with the end of first bending of bellows body one end.
Two angles between the inclined side of described elasticity transition section and first, second parallel edges are obtuse angle.
The syndeton at bellows two ends of the present utility model comprises welding section and elasticity transition section, welding section in the plane crossing bellows axis with the axes normal of bellows, namely welding section and connector adopt downhand welding, the elasticity transition section that syndeton comprises plays the effect of buffering between connector and bellows, make cushioned owing to welding the welding stress produced and reduce between bellows and connector, substantially reduce the impact that welding stress first bending nearest on bellows two ends distance join part causes, it is protected not to be damaged, improve the useful life of bellows.
Further, syndeton shape on the cross section crossing bellows axis is "the" shape structure, "the" shape structure has the first opposing parallel parallel edges, second parallel edges and connection first, the inclined side of the second parallel edges, first parallel edges and inclined side form elasticity transition section jointly, and the first parallel edges is connected with the end of first bending of bellows body one end, second parallel edges is welding section and for welding with connector, the inclined side of two elasticity transition sections tilts to the direction of first bending away from bellows two ends, like this after welding section welds with corresponding connector, because inclined side one end other end that to be connected with the first parallel edges is connected with the second parallel edges, certain elastic space is just there is between connector and the first parallel edges of elasticity transition section, when welding stress is applied on bellows, first there is certain distortion in this tilting section, and cushion stress by the elastic space between the first parallel edges and connector, assume responsibility for the effect of most of stress, nearest first bending of elasticity transition section of would not adjusting the distance of remaining stress produces significantly impact, thus play a protective role.
