Embodiment
Applicant will describe in detail embodiment of the present utility model below by reference to the accompanying drawings; but applicant is not the restriction to technical scheme to the description of embodiment, any changing in the form rather than substance according to the utility model design all should be considered as protection range of the present utility model.
Refer to Fig. 2, Fig. 3 and Fig. 4, the utility model relates to a kind of insulated tension pole of vacuum circuit-breaker, this insulated tension pole 1 comprises housing 11, and described housing 11 adopts insulating material to make cylindricality, and its inside is provided with on the cavity for holding lining 13, outside wall body and is arranged at intervals with ring-type shirt rim.The ring-type shirt rim at interval effectively can increase the electrical insulation properties of housing 11.Described lining 13 is fitted on the inwall of housing 11 cavity, keep geo-stationary motionless to make lining 13 and housing 11, at both, respect to one another offers the plane cooperatively interacted, after lining 13 and housing 11 are fitted, the laminating of two opposite planar can make both keep geo-stationary motionless, namely also relative rotation can not can not occur.Simultaneously in order to prevent lining 13 from outwards dropping out in housing 11 vertically, the surface that lining 13 and housing 11 cooperatively interact also is respectively equipped with the concaveconvex structure of horizontal direction.Described lining 13 is metalwork, after hitting by external force, produces flow of metal, such as, adopt riveting process to order about lining 13 and be out of shape and meet installation requirement.
The centre of lining 13 described in the utility model has cylindric die cavity, and be provided with multiple video disc spring 15 in die cavity, described video disc spring 15 is the annular disc of arch in the present embodiment, obtains elastic force by strain, offers centre bore in the middle of it is axial.A upper boom 14 is provided with above housing 11, described upper boom 14 has a circular protrusion 141 in the longitudinal direction, one end is guide head 142, the other end is connector 143, and described guide head 142 inserts in the centre bore of multiple video disc spring 15 for leading to upper boom 14.Like this, when upper boom 14 is moved radially, the restriction in guide head 142 acceptor center hole and can not deflecting.Connector 143 is for connecting the movable contact rod of vacuum interrupter, the form fixing especially by screw thread completes fixing, thus insulated tension pole 1 provides contact pressure can to dynamic and static contact system, namely after moving contact and fixed contact close, video disc spring 15 in insulated tension pole 1 compresses, and the elastic force of video disc spring 15 is applied on moving contact and produces contact pressure.Circular protrusion 141 is conflicted with video disc spring 15 and is coordinated, be specially circular protrusion 141 towards the anchor ring of video disc spring 15 side and video disc spring 15 is inconsistent, towards connector 143 side anchor ring due to by be positioned at lining 13 opening part capping 16 to stop and can only be mobile at lining 13.Capping 16 is metalwork, the protruding end 162 comprising base 161 and be positioned at above base 161, and offer through hole 163 in the middle of the axis of capping 16, through hole 163 runs through base 161 and protruding end 162.Described connector 143 is through described through hole 163.Preferably, described through hole 163 is the center hole of through columned base 161 and columned protruding end 162.Base 161 is cylindric, and it coordinates with lining 13, specifically refers to: the outside of base 161 has screw thread, accordingly, also have screw thread inside the opening part of lining 13, thus base 161 can be screwed into the opening part of lining 13.The outer rim of base 161 has riveted joint pit 1611, after base 161 is screwed to position, external force hits lining 13, and the indentation, there of riveted joint pit 1611 clamp-oned by lining 13 after being out of shape, base 161 is fixed on lining 13, thus realizes being fixedly connected with of capping 16 and lining 13.Protruding end 162 offers the second pin-and-hole 1621 for coordinating with bearing pin 2, correspondingly, connector 143 offers the first pin-and-hole 1432 for coordinating with bearing pin 2, bearing pin 2 inserts in the second described pin-and-hole 1621 and the first pin-and-hole 1432, thus realizes being connected and fixed between capping 16 and upper boom 14.Connector 143 for upper boom 14 is optimized further, and in order to make connector 143 and through hole 163 not be biased, connector 143 is provided with stage portion 1431, and the external diameter of stage portion 1431 and the diameter compatible of through hole 163 close.The below of housing 11 is fixed with lower beam 12, and lower beam 12 is connected with the connecting lever of vacuum circuit-breaker.
In assembling process, first video disc spring 15 and upper boom 14 are loaded in lining 13, and use external tool that this upper boom 14 is pressed onto service position, again capping 16 is screwed into lining 13(capping 16 with lining 13 for being threaded), after position to be screwed to, the pin-and-hole 1 aimed on upper boom 14 installs bearing pin 2 with the pin-and-hole 2 1621 in capping 16, is finally riveted capping 16 and lining 13.
This kind of insulated tension pole 1, lower beam 12 is maintained static together with upper boom 14 by bearing pin 2, thus lower beam 12 can rely on upper boom 14 to keep not rotating, in the debug process of breaker mechanic property, regulate " overtravel " by turning the nut (not shown) that lower beam 12 is installed, then lower beam 12 there will not be the phenomenon of transfer.
