The invention relates to the field of electric connectors, in particular to an environment-resistant socket and an electric connector component with the environment-resistant socket. The front end of the socket is a plugging end. The socket comprises a socket shell, a socket insulator and a socket contact component, wherein a floating insulator which floats front and back is arranged in the front of the socket insulator in the socket shell; an adapting contact component corresponding to the socket contact component is fixedly arranged on the floating insulator; the inner wall surface of the socket shell and the peripheral surface of the floating insulator are hermetically matched; the adapting contact component and the floating insulator are hermetically matched; a pushing spring is arranged behind the floating insulator in the socket shell; and the push spring forwards pushes against the floating insulator and separates the adapting contact component from the corresponding socket contact component. Even in case of rainy day and a fire disaster, mutual short circuit occurs only between adapting contact components but not between socket contact components. By the environment-resistant socket, the problem that environment resistance of the current electric connector is poor is solved.
