Technical field
The utility model is related to a kind of solid sealed pole of vacuum circuit breaker, belongs to vacuum circuit breaker technical field.
Background technology
More than the pole that vacuum circuit breaker is used in currently available technology using epoxy resin by vacuum circuit breaker once
All sealing is integral for the current carrying element such as current-carrying part vacuum interrupter and upper and lower leading-out terminal, makes the insulation shape of vacuum interrupter
State is completely free from the influence of the external environment, improves weatherability.But the problem of such pole has more：Temperature rise, easily
Cracking, difficult degradation, quality are big, and after the rim charge and product rejection produced during molding for epoxy resin, waste material can not be reused, and
Degradation cycle is long, it is impossible to meet environment-friendly requirement.
In order to solve the above problems, prior art is occurred in that by the use of thermoplastic is used as pole instead of epoxy resin
Insulation shell technical scheme.Compared with traditional epoxy resin pole, the technical scheme can reduce pole weight
Amount about 35%, dielectric strength improves about 50%, and mechanical strength improves 300%-400%, and due to being subtracted using Shooting Technique
Few solidify afterwards program, improves production efficiency.But during injection compression molding, vacuum interrupter is because meeting is by huge note
Modeling filling impulsive force and plastic shrink pressure, the silastic cord breaker of its outer surface cladding are insufficiently resistant to, and vacuum interrupter is deposited
The risk of failure is even damaged in deformation.
The content of the invention
The purpose of this utility model is：A kind of use thermoplastic is provided as the vacuum breaker fixing-sealing of insulation crust
Pole, sets shock resistance protective layer, it is to avoid mould filling between the cushion and pole shell inner surface of vacuum interrupter
Pressure causes product vacuum interrupter to deform, it is ensured that thermoplastic insulation crust uniform force, reduces fraction defective.
The utility model takes following technical scheme：
A kind of solid sealed pole of vacuum circuit breaker, including vacuum interrupter 7, the outside of the vacuum interrupter 7 cladding cushion
8, it is characterized in that：The outside of the cushion 8 cladding high-temperature insulation anti-impacting layer 9, the high-temperature insulation anti-impacting layer 9 with it is outer
The pole housing 1 of the thermoplastic material in portion is connected as a single entity.
Further, the top and the bottom of pole housing 1 be respectively equipped with upper wire outlet seat 2 that thermoplastic connects as one, under
The location structure positioned with mould is respectively provided with wire outlet seat 3, the upper and lower wire outlet seat 2,3.
Further, the location structure is one group of dowel hole or locating slot.
Further, the quantity of the dowel hole 4 is 2-4, and is angularly set.
Further, high-temperature insulation anti-impacting layer 9 is made of high-temperature insulation engineering plastics.
Further, the cushion 8 is made of silastic material.
The beneficial effects of the utility model are：Pass through the cushion in vacuum interrupter and pole shell inner surface
Between be provided with shock resistance protective layer, cause product to become because of too high injection pressure to ensure to be unlikely in process of producing product
Shape；Meanwhile, location structure is set in upper and lower wire outlet seat outer surface, it is ensured that during injection compression molding, upper and lower wire outlet seat positioning is simultaneously
It is not subjected to displacement, and then realizes that the insulation crust thickness of upper and lower leading-out terminal outer surface cladding is uniform.
