Extended box type transformer module

Abstract

The provided extended box-type transformer module comprises at least a circuit board, multiple box-type transformers, multiple terminals extended out of the shell to form interface feet and coupled with the board, and the shell. Wherein, arranging multiple joints on bottom of box body to couple with the board and form at least one layer stack structure. This invention can not only improves process speed and up-to-standard rate, and decreases current product size, but also can extend freely the transform efficiency for automatic production.

Description

technical field [0001] The present invention relates to an expanded box-type transformer module, in particular to an expanded box-type transformer module with at least one layer of stacked structure. Background technique [0002] Coils are widely used in transformers and other electronic devices. Please refer to figure 1 , which shows a three-dimensional schematic diagram of a known transformer. The known transformer 100 is provided with a plurality of coils 111 and coils 112 on the circuit board 101 , wherein the coils 111 can be, for example, primary coils (Primary Coils), and the coils 112 can be, for example, secondary coils (Secondary Coils). Generally speaking, the primary coil is used to connect the external input voltage, while the secondary coil is used to output the output voltage generated by electromagnetic induction. For each coil 111 and coil 112, a predetermined number of turns of wire 119 and wire 120 are manually wound on the iron core 117 and iron core 1...

AI Technical Summary

Problems solved by technology

[0003] However, the coil manufacturing process of the known transformer has many problems to be solved

First of all, it is known that the manufacturing process of transformers is slow and the pass rate is low. Because of the known coils, the wires are manually wound on the iron core, and the other layer is wound only after one layer is wound, which makes the winding process quite time-consuming. and too complicated

In case the operator accidentally makes a mistake in the number of turns on a certain layer, the error cannot be discovered until the inspection, and the coil wires wound up unti...
