Abstract

An improvement in the structure of a lamp base, it includes a lamp socket, a lamp, a pair of connection copper plug, a resistor sheet, a lamp base unit and a pair of wire. A lamp can be plugged into the lamp socket, and there are conductive sheets at both bottom sides of the lamp socket. Each of the conductive sheet at the bottom side of the lamp socket contacts with a connection copper plug, the upper portion of the connection copper plug is in the form of plate, and a resistor sheet can be placed in between the two connection copper plug, and a wire fixture is formed under the connection copper plug which can fix the wire, and the wire is connected to the other lamp base unit of the lamp series, then when the lamp series are turned on, the current will flow to connect copper plug under the lamp socket to light on the lamp in the lamp base of the lamp series, however, if the lamp is burn up or loosen, the resistor sheet will become short to make the lamps in other lamp base units light on as the same; the connection copper sheet is provided with a fixture to fix the resistor sheet at the determined position to prevent loosening.

Claims

1. A lamp base for use in a lamp string having a plurality of lamp bases, the lamp base comprising:

a) a lamp base unit configured to accept therein a lamp socket having a pair of electrical conductors thereon;

b) a pair of electrical wires;

c) first and second connection plugs located within the lamp base unit, each connected to one of the pair of electrical wires and each located so as to contact one of the pair of electrical conductors of the lamp socket, the connection plugs being spaced apart from each other, each connection plug having first and second spaced apart protrusions extending therefrom, the protrusions on each connection plug extending toward the other connection plug; and

,

d) a resistor sheet extending between and in contact with the first and second connection plugs, the resistor sheet located between the first and second protrusions so as to be fixed in position by the first and second protrusions on each connection plug.

2. The lamp base of claim 1 wherein the first and second protrusions are formed integrally with each connection plug.

3. The lamp base of claim 1 wherein the first and second protrusions are formed on plug located on each connection plug.
