The lower bottom surface of a flange of the guide sleeve is provided with four concave pits; and correspondingly, the fixed ring is internally provided with four overturning claws assembled in the concave pits of the guide sleeve. In the anti-twisting structure adopted by the utility model, the structure is simple and effective, no any auxiliary tool is needed for fixing the movable conducting rod when the vacuum arc extinguishing chamber is installed, the rotation of the movable conducting rod is prevented, a corrugated pipe is protected from being born by radial force, and the product quality and the production efficiency are improved.
Description
Technical field
The utility model relates to the anti-kink in the moved end structure of vacuum interrupter in a kind of vacuum circuit-breaker technical field, the especially vacuum circuit-breaker.
Background technology
Vacuum interrupter is the core component of vacuum circuit-breaker, and it is sealed by an insulation crust and dynamic/static contact and forms.Moving contact is linked to each other with moving conductive rod by bellows and constitutes, the thin-walled ripple struction of bellows has determined to bear certain axial force, and the ability of bearing radial force is very little, if moving conductive rod rotation, can give bellows with bigger radial load, will make bellows bursts, the vacuum state of arc control device is damaged, vacuum circuit-breaker just can't operate as normal.At present, the vacuum interrupter of compound inslation is limited because of installing space, can't adopt fixedly moving conductive rod of aid when causing installing, conducting rod rotates during installation, makes the bellows torsional deformation, can cause gas leakage, destroy the vacuum performance of arc control device, influence product quality and production efficiency.
The utility model content
The purpose of this utility model is to provide the anti-kink in a kind of vacuum interrupter moved end structure, when realizing that vacuum interrupter is installed, does not use fixedly moving conductive rod of any aid, prevents its rotation, and the protection bellows is not subjected to radial load, improves product quality and production efficiency.
The technical solution of the utility model is: the anti-kink in a kind of vacuum interrupter moved end structure, comprise moving conductive rod, fairlead, retainer ring, wherein, retainer ring is fixed on the moved end cover plate of arc control device, fairlead is fixed in the retainer ring, and moving conductive rod is in the fairlead endoporus, and moving conductive rod is symmetrical arranged two keyways in the axial direction, be symmetrically arranged with two keys on the endoporus of fairlead is axial, two keys of described fairlead endoporus are assemblied in two keyways of described moving conductive rod.
Described moving conductive rod keyway both sides are provided with chamfering.
The bottom surface of described fairlead flange is provided with four pits.
The inside of described retainer ring is provided with four and turns over pawl.
It is simple in structure that the utility model adopts; be applied in the installation process of vacuum interrupter; need not adopt aid that moving conductive rod is fixed, under twisting force, utilize four of retainer rings to turn over pawl; the fixed guide cover; by the fixing moving conductive rod of fairlead double bond structure, reach and prevent the moving conductive rod rotation, the purpose of protection bellows; improve product quality and production efficiency, reduced production cost.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a cutaway view of the present utility model;
Among the figure: 1-moving conductive rod, 2-fairlead, 3-retainer ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1 and Fig. 2, the anti-kink in the vacuum interrupter moved end that the utility model provides structure comprises moving conductive rod 1, fairlead 2, retainer ring 3, wherein, retainer ring 3 is fixed on the moved end cover plate of arc control device, fairlead 2 is fixed in the retainer ring 3, moving conductive rod 1 is in fairlead 2 endoporus, and moving conductive rod 1 is symmetrical arranged two keyways in the axial direction, is symmetrically arranged with two keys on the endoporus of fairlead 2 is axial, key and keyway match, and key can slide in keyway.Four of four pits of the bottom surface of fairlead 2 flanges and retainer ring 3 inside are turned over pawl and match.
When the assembling arc control device, with retainer ring 3 solderings on the cover plate of the moved end of arc control device, again fairlead 2 is enclosed within on the moving conductive rod 1, allow two keys of fairlead 2 endoporus enter in two keyways of moving conductive rod 1, in order to prevent that keyway acute angle on the moving conductive rod 1 from causing damage to the key of fairlead 2 endoporus, requirement is carried out rounding or chamfering with the both sides of keyway, fairlead 2 is assemblied in the retainer ring 3, four of requirement retainer ring 3 inside are turned over pawl and enter in four pits of fairlead 2 bottom surfaces, retainer ring 3 oral areas are fixed fairlead 2 by the spinning flange, and assembling is finished.
In the vacuum interrupter installation process, utilize retainer ring 3 fixed guide cover 2, and the keyway of two keys of fairlead 2 and moving conductive rod 1 is fastened, and prevents the moving conductive rod rotation like this.This structure has reached under twisting force prevents the fixedly effect of moving conductive rod of kink structure by arc control device self, finally protects bellows not to be damaged.
What the utility model adopted is simple in structure effective, easy for installation.Need not adopt aid that moving conductive rod is fixed in the installation process of vacuum interrupter, directly assemble, it prevents that turning round ability can satisfy installation requirements, reaches the purpose of protection bellows.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
