The invention discloses a mining intrinsic safety type Ethernet signal conversion device, and the device comprises a hot plug protection circuit which is used for accessing a first electric signal through a power interface of the mining intrinsic safety type Ethernet signal conversion device and outputting a second electric signal; the energy limiting circuit is used for limiting the numerical value of the accessed second electric signal; the DC/DC voltage stabilizing circuit is used for adjusting the DC power supply voltage of the second electric signal through a converter to obtain the required voltage so as to provide a power supply for the signal conversion core unit; and the signal conversion core unit is used for realizing signal conversion of BR Ethernet signals accessed by the two-core physical layer interface chip and 100M or gigabit Ethernet signals accessed by the four-core physical layer interface chip under the working condition of the power supply. According to the invention, by reducing Etherne
