A lamp socket unit including an insulating body, several insulating wires, a bottom cover, several copper contact sheets and a lamp bulb. One end of the insulating body has an opening to receive the lamp bulb. Another end of the body is combined with a bottom cover having a wire slot, a copper contact sheet insertion hole and a bottom cover passing hole. The bottom cover has a stay with a reversed hook. One end of copper contact sheet has a taper portion and the another end has a contact portion. The copper contact sheet is arranged and fixed in the insertion hole. The taper portion is fixed in the wire slot, and the contact portion extended to the opening of the body of the lamp bulb. The insulating wire is placed within the wire slot of the body. The taper portion is pierced into the insulating cover of wire and contacted with several copper wires within the wire. The bottom cover presses the wire into the wire slot and the reversed hook fixes the bottom cover on the body. When the lamp bulb is put into the opening of the body, the copper contacted portion is contacted with the conducting wire or the head of lamp bulb so as to form an electric circuit. The rectangular copper contact sheet, has a cross-section in part formed to become elliptical or rectangular shape and has several taper portions. Both ends of the insulating body have a flange, or plug configuration to strengthen the connection of electric circuit and fill a gap when combined.
