Abstract
The utility model discloses a connector assembly of an insulating pull rod. The connector assembly comprises a cylindrical installing portion. A connector is disposed on the front end of the installing portion and is provided with a pin hole. A wearing ring is embedded in the pin hole along the internal diameter of the pin hole. A boss is disposed on the front end portion of the connector. A buffering sleeve is sleeved on the boss. A conductive contact is installed on the front end of the buffering sleeve. A Belleville spring is connected with the back side of the conductive contact in the buffering sleeve. The conductive contact is connected with the boss of the connector via the Belleville spring. The connector assembly of an insulating pull rod has advantages of simple and reasonable structure and convenient installation and debugging, and enhances the wear-resistant performance of the pin hole. The design of arranging the elastic conductive contact on the front end of the connector effectively guarantees the stability of the connection of the connector and a movable contact, prevents partial discharge influence caused by poor contact of the connector, prolongs the service life of the connector, prevents the connector from fracturing, and guarantees the use security of a vacuum circuit breaker.
Description
Technical field
The utility model relates to field of circuit breakers, is specially a kind of adapter assembly of insulated tension pole.
Background technology
Insulated tension pole is the critical component of vacuum circuit-breaker, is determining the speed of cut-offfing and the connecting-disconnecting function of vacuum circuit-breaker.The joint module structure of existing insulated tension pole is reasonable not, after long-time use, the pin-and-hole gap of joint increases, while easily causing breaker operator, moving contact motion is not in place, dynamic/static contact loose contact during combined floodgate, and then making joint corroded by partial discharge, mechanical strength declines, and when serious, may cause joint breaking, straight pin is come off, have potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of adapter assembly of insulated tension pole, joint module structure with insulated tension pole traditional in solution prior art is reasonable not, after long-time use, the pin-and-hole gap of joint increases, while easily causing breaker operator, moving contact motion is not in place, dynamic/static contact loose contact during combined floodgate, and then make joint corroded by partial discharge, mechanical strength declines, when serious, may cause joint breaking, straight pin is come off, have the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of adapter assembly of insulated tension pole, it is characterized in that: include cylindricality installation portion, described installation portion front end is provided with joint, described joint is provided with pin-and-hole, in described pin-and-hole, along internal diameter, is embedded with wear ring, and described joint front end end is provided with boss, on described boss, cover has cushion collar, described cushion collar front end is provided with conductive contact, and the inherent conductive contact dorsal part of described cushion collar is connected with butterfly spring, and described conductive contact is connected on the boss of joint by butterfly spring.
The adapter assembly of described a kind of insulated tension pole, is characterized in that: the contact-making surface of described conductive contact is arranged to hemisphere.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, Installation and Debugging are convenient, improved the anti-wear performance of pin-and-hole, employing is provided with flexible conductive contact design at joint front end, effectively guaranteed the stability that joint is connected with moving contact, prevented that joint from affecting because loose contact is subject to partial discharge, extended the useful life of joint, easy fracture not, has guaranteed the use safety of vacuum circuit-breaker.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
