The present application relates to high-definition multimedia interface, particularly to a new anti-interference high-definition multimedia interface. The interface comprises a male connector and a female connector. The male connector includes a male outer plastic housing, a shield stretch rear housing and a male plastic cable clamp. The female connector includes a female outer plastic housing, an outer shield grounding housing, an inner shield grounding iron housing, a female insulator, a female signal terminal and a female plastic rear plug. The male outer plastic housing and the shield stretch rear housing together form an inner cavity after connecting to each other, in which the male terminal assembly will be received. The female outer plastic housing and the outer shield grounding housing together form an inner cavity after connecting to each other, in which the female terminal assembly is received.
