この発明は、テーパ付碍管、例えば、遮断器等に用いら
れるテーパ付碍管に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tapered insulator tube, for example, a tapered insulator tube used in circuit breakers and the like.
従来の例えば遮断器用碍管の縦断面図を示す第２図のと
おりである。FIG. 2 is a longitudinal cross-sectional view of a conventional insulator tube for a circuit breaker, for example.

の深さを大きくすることによシ確保していた。In general, the surface leakage distance of the insulator tube (4) is determined according to the contamination specifications, and if it is particularly necessary to ensure the required surface leakage distance in the standard insulator tube shape, the body diameter portion (3) of the insulator tube (4) A hat (2) that is formed to protrude more uniformly.
This was ensured by increasing the depth.

汚損仕様がある場合には、もっばら碍管長は長くして汚
損仕様に対処していた。However, as a major factor in determining the insulator cost,
Since the volume of the insulator pipe material when it is formed into a cylindrical shape has an effect, it is better to ensure the surface leakage distance by keeping the depth of the uniformly formed cap to an appropriate size and extending the effective length of the insulator pipe. As the volume of the material tends to decrease,
When there was a dirt specification, the length of the insulator pipe length was usually increased to cope with the dirt specification.

。Since the conventional tapered insulator tube is configured as described above, if there is a stain specification, the overall length of the insulator tube must be made longer than the standard specification, and along with this, the internal parts also have to be longer. It is necessary to make significant changes, and as a result, there is a problem in that it is not easy to reduce costs.
