Abstract: A lamp bulb socket includes an isolator seat with a connection port, an end cover coupled with the isolator seat and having a bracket with a hole, a connection guide terminal with a first contact arm, a connection terminal, a guide terminal with a second contact arm, and a turn switch having a rod with gripping grooves at a first end and four arc notches at a second end opposite the first end. The arc notches received in the end cover and the first end held on the hold of the bracket. The turn switch further includes a terminal contact coupled to the four arc notches such that, when the rod is turned, the terminal contact opens or closes a connection between the connection terminal and guide terminal.

Abstract: Present invention disclosed a threaded lamp socket conversion connector, having the major parts of a metal shell, a metal contact point located at the top portion of said metal shell, an insulator surrounding the metal contact point, a plastic main body, a first terminal piece and a second terminal piece. By relying on the terminal pieces extending and connecting from the structure of a connection port, different power input sources pertaining to the newer generation energy-saving lights can be converted to the prevalent E26/E27 specification via the connection mechanism as disclosed in the present application.

Abstract: Present invention teaches the construction of an E26 lampholder primarily consisting of a housing, a plastic threaded ring, a plastic bracket, two electrode plates where the power lines entering into the internal accommodating space of the housing are connected to the two electrode plates, which provide the electrical connection points, instead of the full internal side walls being the electrical contact and the central point being the electrical contact, making the overall electrical contacts more solid and secure; the separate plastic bracket allows for more versatile options of the present E26 lampholder to be applied in wider possibilities of installation contexts.
