Abstract: A cable for a lamp string is provided herein. The cable may include a number of wires arranged in parallel and aligned in a planar manner, or in a V- or W-like manner. One or more of the wires may be flexible wires or tensile wires. The flexible wire has a core made of a bendy material capable of retaining a new shape, and the tensile wire has a core made of a nonconductive and tensile material.

Abstract: The connector has a base with hooked side boards for joining a top cap. A partition board is placed between the side boards so as to form two slots for housing two metallic plates and two supporting pieces with slant top faces. The metallic plates have two upwardly extended conducting pins. Wires of exposed cores are placed on the supporting pieces. When the top cap is joined to the base, the wires are tightly locked by the top cap and the partition board while the conducting pins firmly contact with the cores. The connector can be quickly configured on a string of lamps and can be conveniently used to cascade multiple strings of lamps.

Abstract: The present invention relates to a series of connected light bulbs for water-tube decoration, characterized in that the serial connection of light bulb is accomplished by stamping a metallic board into a serial connection of conductive legs for the light emitting diode as a whole. After wrapping and fixing the light emitting plate in position by plastic material, it only needs to directly pull the conductive legs apart with appropriate intervals, and the series of connected light bulbs according to the present invention is formed. Such connection of the conductive legs of the bulb gives a whole piece structure with conductivity of high precision and enhances the stability of the light emission to extend the life of its usage and to show its industrial practicability and value.
