Patent ID: 7479038

Claim:
A lamp base with improved structure of electric conduction, comprising: an insulating shell connecting with a luminous tube; an electric cap which electrically connects with the live wire of external power; a T-shape plastic connecting piece of the electric cap; an electric piece which electrically connects with a neutral wire of external power, a basal body of the electric piece is an annular conducting strip which forms metal fixed claws extending into the insulating shell; and a first lead disposes in the insulating shell; the electric cap inserts fixedly into the T-shape plastic connecting piece and disposes at the top of the insulating shell; the annular conducting strip covers the T-shape plastic connecting piece; the metal fixed claws of the electric piece extend into the insulating shell, the electric cap and the annular conducting strip dispose outside of the insulating shell; the electric cap is insulated with the annular conducting strip by T-shape plastic connecting piece; the first lead electrically connects with the electric cap and one electrode of commutation electrocircuit of a lamp base or a lamp base, the electric piece electrically connects with another electrode of commutation electrocircuit of the lamp base or the lamp base.
