A combination structure of a socket and a container is provided. The combination structure includes a container having an opening, and a socket includes a connecting section for being engaged with the opening, a first end extended from the connecting section for being electrically connected to an electronic equipment which is positioned outside the container, and a second end extended from the connecting section for electrically connecting to a circuit unit which is positioned inside the container, wherein a cross-section of the second end is greater than that of the opening and the cross-section of the opening is greater than that of the first end so that the first end is passed through the opening from an inside of the container and exposed to an outside of the container, and the opening blocks the second end for avoiding the second end passing therethrough and fixing the socket inside the container besides mutually fixing the connecting section.
