Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker, and more particularly, it relates to a kind of anti-loose vacuum circuit-breaker.
Background technology
Traditional high-pressure vacuum breaker, comprise three vacuum circuit breaker main and corresponding operating mechanism, each vacuum circuit breaker main comprises vacuum interrupter, be arranged in the insulated tension pole that the moving contact of vacuum interrupter is connected with fixed contact, with moving contact, the bottom of described insulated tension pole is connected with operating mechanism, in the time of work, described insulated tension pole in the vertical direction under the drive of operating mechanism moves and then drives fixed contact contact or separate.
The coupling part of general vacuum circuit-breaker and circuit is all with Access Division, be used for being connected with plug, but it is all larger to be conventionally arranged on Access Division on vacuum circuit-breaker, is used for the plug of clamping also larger, be not easy clamping or clamping is insecure, the bad problem such as easily get loose.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of anti-loose vacuum circuit-breaker, by this anti-loose vacuum circuit-breaker, can fine solution due to the Access Division on vacuum circuit-breaker and the bad problem such as the plug that is attached thereto is all not easy compared with the clamping bringing greatly or clamping is insecure and easily get loose.
For achieving the above object, the utility model provides following technical scheme:
A kind of anti-loose vacuum circuit-breaker, comprise vacuum circuit breaker body, described vacuum circuit breaker body is provided with Access Division, affiliated Access Division comprises insulating case, in described insulating case, be equipped with contact cylindraceous, one end of described contact is connected with claw, described claw is provided with support ring, described catch jacket is provided with insulation lock sleeve, the inwall of the other end of the relative insulating case of described insulation lock sleeve is provided with taper seat, the large end that described taper seat agrees with claw and one end of relative insulating case is taper seat, the inwall of the other end of the relative insulating case of described insulation lock sleeve removably connects with relative one end of insulating case.
By adopting technique scheme, after plug is inserted to Plug Division, operation lock sleeve, be arranged on the taper seat extruding claw on insulation lock sleeve inwall, make claw compress contact, contact will be extruded and apply thrust and plug and Plug Division are formed is firmly connected adding plug, thereby avoid because the Access Division of general vacuum circuit-breaker brings clamping to be not easy or the unstable series of problems of clamping with the plug being attached thereto is excessive.
The utility model is further set to: another part inwall of the relative insulating case of described insulation lock sleeve is provided with screwed hole, and one end of the insulating case matching with described screwed hole is made as thread head.
By adopting technique scheme, after plug inserts Plug Division, can realize by rotating insulated lock sleeve the motion of lock sleeve, thereby drive the extruding of taper seat and claw, and then band moving contact compresses plug, and can be easily the number of turns by rotation and angle realize the size of thrust, prevent that contact and plug from spending being connected of pine or tension, the useful life of prolongation contact.
The utility model is further set to: described insulating case outer wall is close to described thread head and is provided with Dang ring.
By adopting technique scheme, when insulation lock sleeve is in rotary course, can be encircled by Dang the screw-in displacement of spacing insulation lock sleeve, thereby avoid because the phenomenon that the excessive screw-in of insulation lock sleeve makes claw damage contact by pressure occurs.
The utility model is further set to: it is characterized in that, described contact runs through vertically and is provided with some vertical slots and makes its entirety be flap.By adopting technique scheme, make the contraction process of contact become more smooth and easy, make claw apply very little extruding force to contact and just can make contact generation deformation, reduce the extrusion stress between them, thereby extend the useful life of contact and claw.
The utility model is further set to: described contact is provided with stopper slot, and described claw is provided with pressure head, and described pressure head is spacing in stopper slot.
By adopting technique scheme, by the spacing pressure head mode in stopper slot, when insulation lock sleeve is in the process of motion, can not make claw separate with the pressing part of contact, make the process of work more stable.
Compared with prior art, the utility model has the advantage of: can fine solution due to the Access Division on vacuum circuit-breaker and the bad problem such as the plug that is attached thereto is all not easy compared with the clamping bringing greatly or clamping is insecure and easily get loose.
