1, conducting block production is complicated, at high price, and increases pole cavity and shape complexity；
2, conducting block and copper bar, which are flexible coupling, assembles complexity, time-consuming and laborious；
3, conducting block and copper bar, which are flexible coupling to exist, installs hidden danger of not generating heat tightly；
4, conducting block exposes connector boss, and on-insulated protection, there are insulation hidden danger.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of low in cost, easy to assembly, safe
Stable pole moved end joint structure.
In order to achieve the above objectives, the technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of sealing pole
Column moved end joint structure, including pole cavity, the pole cavity is interior to be equipped with vacuum interrupter, and the vacuum interrupter end is set
There is movable end of arc extinguishing chamber, is corresponded on the pole cavity wall and offer joint protective cover at movable end of arc extinguishing chamber, the joint protective
Cover is in semi-cylindrical, and the joint protective cover inner wall convexes to form positioning convex platform, the positioning convex platform end face and movable end of arc extinguishing chamber
Between be connected with copper bar and be flexible coupling, the copper bar be flexible coupling in connection positioning convex platform one end be connected with circuit copper bar, the copper bar
It is flexible coupling and is anchored on positioning convex platform end face by the way that several bolt assemblies pressure is attached with circuit copper bar, the circuit copper bar, which stretches out connector, is protected
Shield port.
Preferably, the pole cavity and joint protective cover are integrally formed.
Preferably, on the positioning convex platform at joint protective cover port recessed formation end slot.
Preferably, the number of the bolt assembly is 2.
Due to the application of the above technical scheme, the utility model has following compared with prior art
The utility model has the advantages that
1, production cost is reduced, pole cavity processing efficiency is improved；
2, component is reduced, structure is simplified, improves pole assembly efficiency；
3, it avoids conducting block and copper bar from being flexible coupling not generate heat tightly hidden danger in the presence of installation；
4, exposed conduct piece is abandoned, insulation performance is improved.
