[0002] As a common decorative element, outdoor light strings are widely used in various occasions, such as gardens, camping, weddings, and festivals, to create a warm, romantic, or festive atmosphere. Since most of the use scenarios are outdoors and the number of lights used at a time is large, good waterproofness and easy installation are essential requirements for the widespread promotion of outdoor light strings.

[0003] The U.S. patent application number is US17469900, which discloses a light string structure, including a power cord, a plurality of light bulbs arranged at intervals along the power cord, the light bulbs including a cap assembly, a light emitting light source and a light-transmitting light bulb; the light emitting light source has an anode terminal and a cathode terminal; the light-transmitting light bulb has an upwardly open light bulb cavity formed inside; the cap assembly includes a cap core, and the cover portion is formed on the periphery of the cap core by overmolding; the cap core includes an inner core body and an inner core top cover provided at the upper end of the inner core body; the power cord is tightly clamped between the inner core body and the inner core top cover; the inner core body is provided with a main body mounting hole opening downwardly, and is provided with anode connection terminals whose lower ends extend into the main body mounting hole. anode and cathode connection terminals; upwardly protruding spike-shaped penetration portions are respectively provided at the upper ends of the anode connection terminal and the cathode connection terminal; the spike portion of the positive terminal passes through the plastic sheath of the positive lead of the power cord and is electrically connected to the wire core of the positive lead; the tip penetration portion of the cathode connection terminal passes through the plastic sheath of the negative lead of the power cord and is electrically connected to the wire core of the negative lead; the upper end of the luminous light source is embedded in the main body mounting hole of the inner core body; the anode terminal of the luminous light source is electrically connected to the anode connection terminal, and the cathode terminal of the luminous light source is electrically connected to the cathode connection terminal; the upper end of the translucent bulb is connected to the lower end of the lamp holder packaging portion, and the lower end of the luminous light source extends into the bulb cavity of the translucent bulb.

[0004] This technical solution solves the problem of manufacturing convenience to a certain extent through modular assembly, that is, the lamp holder, inner core assembly, and bulb assembly can be manufactured separately in advance and assembled on site. However, when assembling on site, this technical solution requires manual on-site puncture of the wiring terminals with the wires for electrical connection, which increases the difficulty of assembly and does not facilitate the quick installation of the light string. In addition, the wires of this technical solution pass through the lamp holder into the inner core and are electrically connected to the wiring terminals. There is no sealing structure between the wires and the lamp holder. Therefore, when used outdoors, rainwater may enter the inner core along the wires, increasing the risk of short circuits in the light string structure.

[0005] The United States Patent (application number is US17848509) discloses a novel plug-in light string structure, including a light string connecting line, a plurality of bulb assemblies arranged in sequence on the light string connecting line, each bulb assembly includes a lamp holder, a light source and a light-transmitting lampshade; the lamp holder includes a plastic inner core, the plastic inner core forms an inner core accommodating cavity, the light string connecting line is provided with positive and negative leads, the positive contact terminal of the positive lead and the negative contact terminal and the negative lead are respectively located in the inner core accommodating cavity; the lamp holder also includes a rubber coating, the rubber coating and the upper end of the plastic inner core, the outer skin of the positive lead, and the outer skin of the negative lead are injection-molded into an integral structure; the light source is provided with positive and negative pins of the light source The upper end of the luminous light source is inserted into the inner core accommodating cavity, the positive pin of the light source is in contact with the positive contact terminal and is electrically connected, and the negative pin of the light source is in contact with the negative contact terminal and is electrically connected; an insertable plastic head is provided at the upper end of the luminous light source, and the light source is plugged in and out of the inner core accommodating cavity of the plastic inner core through the insertable rubber head. The insertable plastic head can ensure the contact stability between the positive pin of the light source and the positive contact terminal, and the negative pin of the light source and the negative contact terminal; a plastic isolation column for isolating the positive lead and the negative lead is also embedded in the inner core accommodating cavity, and the plastic isolation column is located between the positive lead and the negative lead; the upper end of the plastic isolation column is injection-molded with the rubber-coated part as an integrated structure.

[0006] This technical solution is achieved by injection molding the rubber coating of the lamp holder, the upper end of the plastic core, the outer skin of the positive lead, the outer skin of the negative lead, and the plastic isolation column into an integrated structure, and by directly setting the positive and negative leads on the wires, and achieving a stable electrical connection with the light source through the plug-in plastic head and plastic isolation column, replacing the solution of achieving electrical connection between the light source and the wires by puncture, which to a certain extent solves the problem of waterproofing of the light string.

[0007] However, this technical solution uses a plug-in method instead of a puncture method to achieve electrical connection between the wires and the light source, which requires the addition of intermediate components such as plug-in plastic heads and plastic isolation columns, which will also make the overall structure of the light string more complicated.
