Network transformer

The invention provides a network transformer which comprises a shell, a plurality of main coils and first groups of connecting pins. The main coils are arranged in the shell, the first connecting pins are arranged on the shell, each main coil comprises an amorphous magnetic core, the first groups of connecting pins include a first group of inner pins and a first group of outer pins, the first group of inner pins are electrically connected with the main coils, the first group of outer pins are used for being connected onto an external circuit board, the first group of inner pins are integrally and conductively connected with the first group of outer pins, and each two adjacent inner pins of the first group of inner pins are spaced from each other by a first preset distance. The network transformer has the advantage that purposes of improving the galvanization strength of the network transformer and increasing transmission power are achieved.
