In the such scheme, described package casing is provided with on the limit wall of primary connection terminal at it, in the outside of whole primary connection terminals, also is arranged with the seal boss of projection.
In the such scheme, described seal boss adopts flexible insulating material to make.
In the such scheme, described package casing, insulating protective layer and seal boss adopt silicon rubber to make.
In the such scheme, described seal boss exceeds described primary connection terminal.
In the such scheme, the roof of described package casing is provided with at least one groove, and described each primary connection terminal is arranged in described groove.
In the such scheme, the quantity of described groove is identical with the quantity of primary connection terminal, and described each primary connection terminal is arranged in a corresponding groove, and the limit wall of described each groove is a seal boss.
In the such scheme, the basic configuration of described package casing is square.
In the such scheme, the bottom of described package casing is provided with the mounting panel of protrusion, and described each mounting panel is provided with installing hole.
The present invention has positive effect: among (1) the present invention, described each primary connection terminal is the binding post that is provided with screw, is arranged with insulating protective layer on the outer wall of described each binding post.The voltage transformer of this kind structure is when fitting operation, and is comparatively convenient.(2) among the present invention, described package casing is provided with on the limit wall of primary connection terminal at it, in the outside of whole primary connection terminals, also is arranged with the seal boss of projection.After product of the present invention is in place, can allows the outer ends of seal boss compacted, thereby in primary connection terminal and anti-creep electric insulation boss all be sealed in, prevent that effectively spot from entering wherein.
