Description
Technical field
The present invention relates to a kind of pole, relate in particular to the structure that is flexible coupling in this pole and is connected with the moving contact of pole.
Background technology
The effect of pole is through the vacuum interrupter extinguish arcs, to reach the purpose of cut-offfing overload current, protection power consumption equipment.
What the connected mode of inner arc control device moving conductive rod of pole and following outlet was common in the prior art has two kinds, the mode that promptly is flexible coupling and the mode that is slidingly connected.
By Fig. 1 visible (common be flexible coupling): this pole 1 is embedded vacuum interrupter 2; The upper end of moved end 3 is in vacuum interrupter 2; 3 lower ends, moved end that pass vacuum interrupter 2 link to each other with 4 the end of being flexible coupling; Below this end of 4 of being flexible coupling insulated tension pole 5 is installed, 4 the other end of being flexible coupling links to each other with following outlet seat 6.
The advantage of this mode is: assembling is simple, and arc control device are had a common boundary with being flexible coupling, and contact-making surface is few, and material cost is lower.Shortcoming is because contact area is little, can only be used for the small rated currents product.
By Fig. 2 visible (being slidingly connected): these pole 11 embedded vacuum interrupters 12; The upper end of moved end 13 in vacuum interrupter 12,, 13 lower ends, moved end that pass vacuum interrupter 12 connect as one through double threaded screw 19 and moving contact 14; Moving contact 14 lower ends link to each other with insulated tension pole 15; Moving contact 14 passes down the centre bore of outlet seat 16, and moving contact 14 keeps sliding contact with spring touch finger 17 in the process of moving up and down, and spring touch finger 17 is embedded in down in the draw-in groove 18 of outlet seat 6.
The pole that adopts above-mentioned spring touch finger mode to connect; It is big that contact area becomes; Can increase the rated current of pole; But on the structural design of spring touch finger, there are a lot of problems, after circuit breaker cut-offs for several times repeatedly, draw screw thread bad easily like the moved end connecting portion of split interconnection system moving contact (conducting position) and arc control device; There is the problem of dismounting difficulty in the one interconnection system; The draw-in groove size tolerance requirements of spring touch finger and mounting spring fingertip is extremely strict, usually causes problems such as the big or contact resistance of arc control device contact counter-force is bigger than normal if both cooperations go wrong, and is installed in the divide-shut brake speed that can have influence on mechanism in the mechanism.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of pole that abnormity is flexible coupling that has, and are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
The present invention includes: the vacuum interrupter in pole; The upper end of moved end is in vacuum interrupter; The lower end that passes the moved end of vacuum interrupter links to each other with the end that an abnormity is flexible coupling; Following and the insulated tension pole of the end that this abnormity is flexible coupling links to each other; The other end that abnormity is flexible coupling combines as a whole through screw and following outlet seat; The lower end of said moved end is shaped as the external taper shape, described abnormity be flexible coupling with the junction, lower end of moved end be shaped as one internal taper arranged cylinder; The junction of the other end that described abnormity is flexible coupling through screw and following outlet seat be shaped as a binding face; On described binding face, tapped through hole is arranged; Described screw from the through hole of following outlet seat to tapped through hole.
Compared with prior art, the invention has the beneficial effects as follows: increased the moved end of arc control device and the contact area that is flexible coupling, increased through-current capacity, help the reduction of loop resistance again, and Assembly part has been few, also simple in the design than the mode of being slidingly connected.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
Visible by Fig. 3, Fig. 4: as to the present invention includes: the vacuum interrupter 22 in pole 21; The upper end of moved end 23 is in vacuum interrupter 22; A be flexible coupling end of 24 of lower end and an abnormity that passes the moved end 23 of vacuum interrupter 22 links to each other; The be flexible coupling following and insulated tension pole 25 of an end of 24 of this abnormity links to each other; Be flexible coupling 24 the other end of abnormity combines as a whole through screw 27 and following outlet seat 26; The lower end of said moved end 23 is shaped as the external taper shape, described abnormity be flexible coupling 24 with the junction, lower end of moved end 23 be shaped as one internal taper arranged cylinder 241; The be flexible coupling binding face 28 that is shaped as of 24 the other end junction through screw 27 and following outlet seat 26 of described abnormity; On described binding face 28, tapped through hole 29 is arranged; Described screw 27 is from through hole 261 to the tapped through hole 29 of following outlet seat 26.
Pole of the present invention inside comprises vacuum interrupter; The moved end of arc control device (moving conductive rod) part is in arc control device; The moved end of arc control device is flexible coupling with abnormity and links to each other, and abnormity is flexible coupling and links to each other with insulated tension pole, and the abnormity other end that is flexible coupling is connected as a single entity through screw and following outlet seat.What the part that is connected in the moved end of the abnormity built-in end that is flexible coupling and the arc control device that go out adopted is that tapering connects; Promptly require the moved end of arc control device that certain external taper is arranged; The built-in end that abnormity is flexible coupling also has certain internal taper, and there is corresponding relation in both taperings.
It is to be flexible coupling abnormity through the circular port that screw passes down the outlet seat from the outside to tighten that the applying end that abnormity is flexible coupling has the connected mode of tapped through hole and following outlet seat.Through the connected mode of ecto-entad, avoided because the pole intracavity space causes the problem that the difficulty that is flexible coupling is installed for a short time.Outside in twist screw owing to adopt, not be used in the pole inner chamber excessive die cavity is set.Practiced thrift the pole volume inside, made design more flexible, made the pole assembling simpler.
The present invention has overcome in the common connected mode that is flexible coupling because the through-current capability difference problem that contact-making surface causes for a short time; Also overcome simultaneously the big and loop resistance problem of unstable of the frictional force that is slidingly connected.
