description The utility model provides a mechanical seal and electrical contact mounting structure of a locomotive antenna device. The structure comprises an antenna base plate, an antenna plug, an antenna mounting seat and a sealing ring. A mounting hole and a second groove are arranged on the antenna mounting seat. A first groove is arranged on the antenna base plate. When the antenna base plate and the antenna mounting seat are fastened and connected, the antenna plug passes through the mounting hole in the antenna mounting seat. The sealing ring is clamped between the first groove and the second groove. The height value of the sealing ring is greater than the sum of the groove depth values of the first groove and the second groove. According to the utility model, the electrical contact performance of the antenna device is ensured; the sealing ring is clamped between the first groove and the second groove; and upper and lower ends of the sealing ring respectively from a mechanical seal structure with the first groove and the second groove, which effectively prevents water, dust and the like coming into the antenna device.
