Description
Technical field
This utility model relates to power switchgear, and especially one has thermoplastic and makes
The embedded pole part of insulating sheath.
Background technology
(it is also called solid owing to having the embedded pole part of the insulating sheath that thermoplastic is made
Sealed pole) bottom conducting end to bottom mounting surfaces distance limit, cause the table inside insulant
Identity distance is less than normal from i.e. creep age distance.For increasing creep age distance, current solution and mainly asking
Topic is: additionally increase, at pole bottom cavity mouth, the sealing lid that an insulant makes,
By completely isolated with chopper metal framework for pole cavity inside.The advantage of this scheme is sealing pole
The inner side of the insulating sheath of post self be not perpendicular to the rib of axis, i.e. mould slide block surface in
Straightened condition, can conveniently realize automatic demoulding.But its shortcoming is also apparent from: one is the increase in
Sealing cover, and seal request is higher, assembly process is numerous and diverse；Two is to seal lid by pole sky
Chamber is closed, and is easily caused pole radiating condition poor, temperature rise.
Summary of the invention
In order to overcome the embedded pole part with the insulating sheath that thermoplastic is made
The deficiency that assembly process is numerous and diverse, heat dispersion is poor, this utility model provides one to be effectively ensured
Radiating effect avoids the embedded pole with the insulating sheath that thermoplastic is made that higher temperatures rises
Parts.
This utility model solves its technical problem and be the technical scheme is that
A kind of embedded pole part with the insulating sheath that thermoplastic is made, including pole portion
Part body, hardware body top, described pole is provided with conducting terminal, and the middle part of described pole parts sets
Have lower conducting terminal, bottom described lower conducting terminal and pole hardware body between inwall be provided with
Interior creep distance muscle.
Further, it is square bottom the hardware body of described pole, and at least one face of described bottom
It is provided with interior creep distance muscle.
Or: rounded bottom the hardware body of described pole, described interior creep distance muscle is the most linear.
The beneficial effects of the utility model are mainly manifested in: 1, simplify assembly process, be effectively ensured
Radiating effect avoids higher temperatures liter；2, automatic demoulding, working (machining) efficiency is higher.
