Abstract

The present invention discloses a production method for micro-transformers, and the method includes the following steps: an iron core, which has magnetic properties, is provided with a gap for fixing on a mould; the iron core is positioned into the mould; plastic is injected into the mould and is solidified so as to closely wrap the periphery of the iron core. A micro-transformer is provided, which comprises an iron core and a rolling spindle, wherein, the iron core is produced with magnetic material and is provided with a gap for fixing on the mould, and the rolling spindle closely wraps the periphery of the iron core. The rolling spindle is directly molded to bundle the periphery of the iron core by dint of a single mould. The present invention adopts the model of integrative forming to make the rolling spindle wrapped onto the periphery of the iron core, thereby simplifying manufacturing procedures, reducing the cost of production and assembly, avoiding the wanting in the process of assembling electronic components, and improving the reliability and the good yield of products.

Description

technical field [0001] The invention relates to a micro-transformer structure used in optical equipment such as cameras or small electronic equipment and a manufacturing method thereof. Background technique [0002] In the prior art, in some miniaturized or miniaturized digital products, it is necessary to use a transformer to boost the low voltage of the power supply battery to a high voltage in order to realize its functions, such as charging and flashing. Due to the size of digital products Small, so the volume of the transformer is very small and cannot take up too much space. The structure of the existing transformer, as shown in Fig. 1 and Fig. 2, adopts two independent base bodies 7, 8 and the iron core to form after assembly, it has the following disadvantages, the two independent base bodies 7, 8 and the iron core The assembly is inconvenient, the production process is complicated and the cost is high, and the characteristics of the finished product made with this ...
