Abstract
The utility model provides an insulating casing's solid utmost point post that seals with make by thermoplastic material, is including the utmost point post body and square base, the body is located square base, the upper portion of body sets up conductive terminal, the middle part of body sets up down conductive terminal, and the outer wall that is located down the utmost point post body between conductive terminal and the base is equipped with lower rib form rib, the bottom surface four corners of square base is equipped with the mounting hole respectively the bottom surface of base is equipped with the three dimensional structure of fretwork, and this three dimensional structure makes the wall thickness of base be even. The utility model provides a do not lose the insulating casing's solid utmost point post that seals with make by thermoplastic material of mechanical rigidity under the prerequisite of guaranteeing homogenizing wall thickness.
Description
Technical field
This utility model relates to pole, especially a kind of pole with the insulation crust being made up of thermoplastic.
Background technology
Under normal circumstances, the installation dimension of pole, spacing and lower conducting end such as upper and lower conducting end have become standard size with the spacing installing bottom surface.But in pole use procedure, due to the steam in air and dust pollution, still have the possibility causing that its insulant surface produces electric leakage, it is therefore desirable to increase the surface distance of insulant, i.e. creep age distance between upper and lower conducting end；Pole, when closing of circuit, must have certain pressure between the dynamic and static contact of vacuum interrupter, could form electrical connection reliably；And this pressure acts on pole insulating sheath top by vacuum interrupter and upper conducting end, constitute pulling force vertically with the bottom mounting surfaces being installed on circuit breaker frame.
The pole of the insulation crust being made up of thermoplastic, is provided with ribbed rib between lower conducting terminal and pedestal, for improving creep age distance between the two；But, at base part, in order to realize uniform wall thickness, outer wall is provided with L-shaped three dimensional structure；This structural penalties mechanical stiffness；Furthermore, the supernumerary structure increasing creep age distance is not set between upper and lower conducting terminal.
Summary of the invention
The deficiency that when in order to overcome the pedestal of existing pole to ensure uniform wall thickness again, mechanical stiffness is less, this utility model provides a kind of pole with the insulation crust being made up of thermoplastic not losing mechanical stiffness under the premise ensureing uniform wall thickness.
This utility model solves its technical problem and be the technical scheme is that
A kind of pole with the insulation crust being made up of thermoplastic, including pole body and square base, described body is positioned on square base, the top of described body arranges conducting terminal, the middle part of described body arranges lower conducting terminal, the outer wall of the pole body between lower conducting terminal and pedestal is provided with lower ribbed rib, the corner, bottom surface of described square base is respectively equipped with installing hole, be provided with the three dimensional structure of hollow out in the bottom surface of described pedestal, this three dimensional structure makes the wall thickness of pedestal be uniform.
Further, the outer wall of the pole body between described upper conducting terminal and lower conducting terminal is provided with ribbed rib.
Further, described upper conducting terminal and lower conducting terminal are positioned at the side of pole body, and the outer wall at the opposite side of pole body is provided with vertical ribbed rib.
Further, described lower ribbed rib, upper ribbed rib all take the shape of the letter U structure, and are perpendicular to the axially arranged of pole body.
The beneficial effects of the utility model are mainly manifested in: 1, do not lose mechanical stiffness under the premise ensureing uniform wall thickness；2, there is longer creep age distance between two electric terminals, and there is higher mechanical strength.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the pole with the insulation crust being made up of thermoplastic.
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
See figures.1.and.2, a kind of pole with the insulation crust being made up of thermoplastic, including pole body and square base, described body is positioned on square base, the top of described body arranges conducting terminal, the middle part of described body arranges lower conducting terminal, the outer wall of the pole body between lower conducting terminal and pedestal is provided with lower ribbed rib 4, the corner, bottom surface of described square base is respectively equipped with installing hole, be provided with the three dimensional structure 3 of hollow out in the bottom surface of described pedestal, the wall thickness that this three dimensional structure 3 makes pedestal is uniform.
Further, the outer wall of the pole body between described upper conducting terminal and lower conducting terminal is provided with ribbed rib 1 so that have bigger creep age distance between the two.
Further, described upper conducting terminal and lower conducting terminal are positioned at the side of pole body, and the outer wall at the opposite side of pole body is provided with vertical ribbed rib 2.Whole pole body is made to have higher mechanical stiffness.
Further, described lower ribbed rib, upper ribbed rib all take the shape of the letter U structure, and are perpendicular to the axially arranged of pole body.This is a kind of conventional arrangement, naturally it is also possible to adopt other modes.
In the present embodiment, the residual wall thickness of at least base part being arranged so that insulation crust of three dimensional structure 3 is uniform, and this makes to save material when not losing mechanical strength energy.Described three dimensional structure is strengthen variable cross-section at lower section pedestal mounting screw holes muscle, it is also possible to be other structures.
