Abstract
The utility model provides a creep distance muscle adds in insulating sheath's embedded pole piece spare tool with thermoplastic material makes, the bottom of this embedded pole piece spare of is circularly, just to be the spiral linear for the creep distance muscle of bottom, stretches into the outer wall of the module of the bottom of embedded pole piece spare is equipped with the spill helix line that is used for the interior creep distance muscle of processing, the module with be used for driving the rotatory outer drawing of patterns drive arrangement who moves simultaneously of module and be connected. The utility model discloses simplify the assembly process, effectively guarantee the radiating effect to avoid higher temperature rise.
Description
Technical field
This utility model relates to power switchgear, the processing unit (plant) of a kind of embedded pole part.
Background technology
Owing to having embedded pole part (being also called pole) the bottom conducting end of the insulating sheath that thermoplastic is made to bottom mounting surfaces distance limit, cause the surface distance inside insulant i.e. creep age distance less than normal.For increasing creep age distance, current solution and subject matter 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 the rib that the inner side of the insulating sheath self of pole is not perpendicular to axis, i.e. mould slide block surface is 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, and assembly process is numerous and diverse；Two is to seal lid to be closed by pole cavity, is easily caused pole radiating condition poor, temperature rise.
Summary of the invention
For the deficiency that the assembly process overcoming the embedded pole part with the insulating sheath that thermoplastic is made is numerous and diverse, heat dispersion is poor, this utility model provides and a kind of simplifies assembly process, the embedded pole part with insulating sheath that thermoplastic make that radiating effect avoid higher temperatures rise in creep distance muscle processing unit (plant) is effectively ensured.
This utility model solves its technical problem and be the technical scheme is that
Creep distance muscle processing unit (plant) in a kind of embedded pole part with the insulating sheath that thermoplastic is made, the bottom of this embedded pole part is rounded, and the creep distance muscle of described bottom is the most linear, the outer wall of the module stretching into the bottom of described embedded pole part is provided with the spill helix lines for processing interior creep distance muscle, and described module is connected with the demoulding driving means for driving module to rotate outer shifting.
Further, described module is provided with overhanging section, and described overhanging section is provided with worm gear, described worm gear and worm engaging, described worm screw and the output shaft linkage driving motor.It is of course also possible to use other type of drive.
The beneficial effects of the utility model are mainly manifested in: 1, simplify assembly process, radiating effect is effectively ensured avoids higher temperatures liter；2, automatic demoulding, working (machining) efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the lower lumen schematic diagram of the embedded pole part with the insulating sheath that thermoplastic is made.
Fig. 2 be insulating sheath embedded pole part in the schematic diagram of creep distance muscle processing unit (plant).
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
See figures.1.and.2, creep distance muscle processing unit (plant) in a kind of embedded pole part with the insulating sheath that thermoplastic is made, the bottom of this embedded pole part is rounded, and the creep distance muscle 4 of described bottom is the most linear, the outer wall of the module 1 stretching into the bottom of described embedded pole part is provided with the spill helix lines for processing interior creep distance muscle, and described module 1 is connected with the demoulding driving means for driving module to rotate outer shifting.
Further, described module is provided with overhanging section, and described overhanging section is provided with worm gear 2, and described worm gear 2 engages with worm screw 3, described worm screw 3 and the output shaft linkage driving motor.It is of course also possible to use other type of drive.
The work process of the present embodiment is: described module 1 is put into before moulding the bottom of described embedded pole part, after injection mo(u)lding, controls demoulding driving means and module 1 rotates from the bottom of described embedded pole part pull-out.
