By the above-mentioned description to the utility model structure it is found that compared to the prior art, the utility model has following excellent
Point:
1, the utility model is for existing same size, with the transformer of scale, by setting the second pin portion
It is placed on insulation cover, winding wire must bypass coiling hook portion and insulation cover and connect with the second pin portion, not only significantly
The safety distance for increasing transformer, so that transformer, in the case where not changing volume, the safety that can meet more high standard is wanted
It asks, and overcomes traditional transformer that a large amount of manual work is needed to increase safety distance, simplify production process, reduction is produced into
This, is highly adaptable to current automated production mode, further increases production efficiency.
2, the setting of the utility model coiling hook portion, the safety distance that can not only increase transformer are outer, additionally it is possible to avoid
Conducting wire pull down when and coil contact, further increase the safety and stability of transformer.
3, the utility model can be avoided magnetic core and insulation cover directly contradict, so that magnetic core by the setting of interior step
Certain space is reserved between insulation cover, so that the work difference of core thickness be avoided to influence insulation cover and winding bobbin
Horizontal position, and then ensure that the first pin portion and the second pin portion are in same level height；The limit of trip is arranged, can
The relative position for distinguishing winding bobbin and insulation cover, thereby further ensures that the first pin portion and the second pin portion in horizontal plane
On spacing, i.e., so that the spacing between the first pin portion and the second pin portion is fixed, precisely.
