AI Technical Summary
Technical Problem
Existing transformers require a large installation space, which is not conducive to miniaturization design, and involve many processing steps, resulting in high production costs.
Method used
A planar transformer frame with high space utilization is designed. The bent part of the PIN pin abuts against the solder pad, reducing the encroachment on the edge position. It is produced by one-piece injection molding, which simplifies the processing steps.
Benefits of technology
This achieves efficient utilization of transformer installation space, reduces production costs, and improves production efficiency and equipment space utilization.
