Abstract
The utility model discloses an injection molding type electrode post which mainly comprises a shell body, an upper electric conduction member, a fixed screw, a vacuum arc-extinguishing chamber, and a lower electric conduction member. The injection molding type electrode post is characterized in that the top end of the shell body is provided with a plastic cover, the fixed screw is arranged below the plastic cover, the inner upper end of the shell body is provided with the upper electric conduction member, the vacuum arc-extinguishing chamber is placed below the upper electric conduction member, the lower part of the shell body is provided with a transverse round cylinder, the lower electric conduction member is arranged in the transverse round cylinder, and the fixed screw is connected with the vacuum arc-extinguishing chamber after pressing and running through the upper electric conduction member. The beneficial effects are that because the vacuum arc-extinguishing chamber is not an injection molding embedded member of the shell body and is placed in assembly processes, the vacuum arc-extinguishing chamber can be prevented from being damaged by pressing force generated in shell body injection molding processes and contraction force in cooling processes, and finished products are improved in qualified rate; because the shell body is shaped as a cylinder and only the upper end of the shell body is provided with an embedded member, a main cylinder body is uniform in wall thickness, plastic shrinkage deformation of the surface of the shell body can be reduced, and product quality can be improved.
Description
Technical field
The utility model relates to a kind of pole of high-pressure vacuum breaker.
Background technology
Vacuum circuit-breaker is the core component in power switch cabinet, is mainly used to distribute electric energy, and can cut off rapidly circuit when power circuit and motor such as are short-circuited at the fault, guarantees that power supply safety is reliable, guarantees that nucleus equipment is without prejudice simultaneously.Pole is vacuum circuit-breaker and the outside vitals being connected, existing pole manufacturing technology generally adopts epoxy resin Pouring note technology, once after the pole damage with epoxy resin Pouring note, epoxy resin can not decompose, the metalwork of the inside can not reclaim, the first sample long-term existence of meeting image-stone, contaminated environment, in recent years, start the exploitation of injection molding pole, for example: number of patent application 201210296334.9, the manufacturing technology that title < < injection molding pole > > introduces, be exactly by vacuum interrupter, after upper electric-conductor and the assembling of lower electric-conductor, using it as inserts, the correspondence position that packs polar pole die into, to mold heated and injection moulding, make pole, but the conforming product rate of this manufacturing technology is lower, because the powerful internal stress producing during injection moulding is easily damaged vacuum interrupter, also because the wall thickness of moulding is inconsistent, pole surface easily produces serious contraction distortion, affect product quality.
Utility model content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, proposes a kind of injection molding pole that can improve product qualified rate.
The utility model is to realize by following technical scheme: a kind of injection molding pole, mainly comprise housing, upper electric-conductor, fixed screw, vacuum interrupter, lower electric-conductor, it is characterized in that: there is individual plastic closure on housing top, below plastic closure, there is a piece fixed screw, in described housing, there is upper electric-conductor upper end, under upper electric-conductor, place vacuum interrupter, a horizontal cylinder is arranged at the bottom of housing, electric-conductor under placing in horizontal cylinder, being connected of electric-conductor and vacuum interrupter pushed down and passed to described fixed screw.
A kind of syndeton of injection molding pole: plastic closure covers in case top, under plastic closure, there is fixed screw, fixed screw is pushed down and is passed electric-conductor and is connected with the internal thread hole on vacuum interrupter top in housing, vacuum interrupter lower end is connected with the inner of lower electric-conductor, and the outer end of lower electric-conductor and upper electric-conductor is for being connected with electrical network.
Described housing is the moulding that is cylinder shape;
Described vacuum interrupter, fixed screw, upper electric-conductor and lower electric-conductor are prefabricated components;
Internal thread hole is arranged at described vacuum interrupter top, and internal thread hole and fixed screw are supporting;
Inserts when described upper electric-conductor is housing injection moulding, has a vertical direction circular hole of wearing fixed screw in upper electric-conductor;
Upper electric-conductor in described housing and the vacuum interrupter of rear placement are veneer crimping.
The beneficial effects of the utility model are:
Because vacuum interrupter is not the injection moulding inserts of housing, assembling time is placed into, and the pressure while having avoided housing injection moulding and the destruction of convergent force when cooling to vacuum interrupter have been improved the qualification rate of finished product;
Because housing is cylindrical shell, only have upper end to have inserts, so main cylinder wall thickness is even, can reduce the plastic shrink distortion of surface of shell, improve the quality of product.
