A three-dimensional convertor includes a housing and a socket interior arranged inside the housing. The socket interior includes clapboards, a live wire plug bush conductive sheet, a naught wire plug bush conductive sheet and an earth wire plug bush conductive sheet. The clapboards include a first clapboard, a second clapboard, a third clapboard and a fourth clapboard which are sequentially stacked. The naught wire plug bush conductive sheet is located between the first clapboard and the second clapboard, the earth wire plug bush conductive sheet is located between the second clapboard and the third clapboard, the live wire plug bush conductive sheet is located between the third clapboard and the fourth clapboard. The housing includes at least two jack surfaces each of which is provided with a jack. The jack is corresponding to the live wire plug bush conductive sheet, the naught wire plug bush conductive sheet and the earth wire plug bush conductive sheet.
