The remarkable result of the present invention is: realize pilfer-proof closure, nameplate, secondary by interface arrangment embedding
The installation of part is fixed, and improves production efficiency, reduces cost of labor；Use transparent pilfer-proof closure
And installed by pressing clamping, not only increase installation effectiveness, and be easy to butted line situation and enter
Row checks；Secondary inserts is provided with pressuring line groove, effectively prevent the end of a thread and burr occurs, have
Effect avoids the potential safety hazard such as high-voltage breakdown or the short circuit of wire short；By four, fixed block is installed
Can realize the fixing of transformer, compared to traditional fixed form, raw-material utilization rate is more
Height, grafting need not position after installing fixed block, and the fixed installation of transformer more saves time faster
Prompt.
