[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] refer to Figure 1-4 A light string connection structure includes: a main line 1 having a first conductor 11 and a second conductor 12; a circuit board 2 connected to the first conductor 11 and the second conductor 12, and having a parallel circuit or a series circuit on the circuit board 2; and lamps 3 having two wiring terminals, the two wiring terminals being connected to the parallel circuit on the circuit board 2 to connect multiple lamps 3 in parallel, or the two wiring terminals being connected to the series circuit on the circuit board 2 to connect multiple lamps 3 in series. Optionally, reference Figure 1-2 The parallel circuit includes: a first welding point 21, a second welding point 22, a third welding point 23, and a fourth welding point 24 arranged at intervals, wherein the first welding point 21 is connected to the second welding point 22, and the second welding point 22 is connected to the fourth welding point 24; the first wire 11 and the second wire 12 are respectively welded to the first welding point 21 and the second welding point 22; the two terminals of the lamp 3 are respectively welded to the third welding point 23 and the fourth welding point 24. Optionally, refer to Figure 3-4The series circuit includes: a fifth welding point 25, a sixth welding point 26, a seventh welding point 27, an eighth welding point 28, and a ninth welding point 29 arranged at intervals, the sixth welding point 26 is connected to the eighth welding point 28, and the seventh welding point 27 is connected to the ninth welding point 29; the first wire 11 is welded to the fifth welding point 25, and the second wire 12 is disconnected and welded to the sixth welding point 26 and the seventh welding point 27 respectively; the two connection terminals of the lamp 3 are welded to the eighth welding point 28 and the ninth welding point 29 respectively.
[0032] As will be understood, the first and second conductors 11, 12 are conductive components of the main line 1 and may be, for example, enameled wire or copper wire with insulating colloid, but are not limited thereto. The first, second, third, fourth, fifth, sixth, seventh, and ninth solder joints 21, 22, 23, 24, 25, 26, 27, 28, and 29 are all exposed structures, such as, for example, flat metal sheets or protruding metal solder joints, but are not limited thereto. The lamp 3 is a lighting component and may be, for example, a light bulb, a lamp bead, or an LED, but is not limited thereto.
[0033] Thus, when assembling a parallel circuit, the first and second wires 11 and 12 are stripped and directly soldered to the first and second solder joints 21 and 22. The two terminal blocks on the lamp 3 are then soldered to the third and fourth solder joints 23 and 24, respectively. When assembling a series circuit, the first wire 11 is split and soldered to the fifth solder joint 25. The second wire 12 is split and disconnected to form two interface ends, which are then soldered to the sixth and seventh solder joints 26 and 27, respectively. Finally, the two terminal blocks on the lamp 3 are soldered to the eighth and ninth solder joints 28 and 29, respectively. Both structures are simple and quick to assemble. Because the solder joints are isolated from each other and the connecting wires between them are all internal to the circuit board 2, the spacing between the wires does not affect each other, eliminating the need for wrapping with insulating tape.
[0034] In some embodiments, referring to Figures 3-4, the circuit board 2 is provided with a through slot 7 between the sixth solder joint 26 and the seventh solder joint 27. Here, the second wire 12 can be cross-sectioned without cutting it and directly soldered to the fifth and sixth solder joints 26. A cutter can then be aligned with the through slot 7 to cut the second wire 12, which can speed up installation.
[0035] In some embodiments, reference Figure 5-6 The lamp 3 is connected to the third welding point 23 and the fourth welding point 24 respectively through two hanging wires 4. In this way, the hanging wires 4 extend the lamp 3, so that the lamp 3 forms a hanging state.
[0036] In some embodiments, a packaging shell 5 is also included to wrap the circuit board 2. It is understandable that the packaging shell 5 is a component that wraps and protects the circuit board 2, and can be, for example, a shell package or a colloid package, etc., but is not limited thereto. Here, taking the shell as an example, the packaging shell 5 is provided with a groove 51 for embedding the circuit board 2, and a first through hole 52 for the main line 1 to pass through is provided on the left and right sides, and a second through hole 53 for the lamp 3 to be connected is provided at the bottom. It is understandable that the groove 51 can embed and position the circuit board 2 to prevent it from loosening. The packaging shell 5 can be set into a two-half assembly structure. During installation, a colloid can be added to the groove 51 to position and seal the circuit board 2. Furthermore, a hook 6 is installed on the packaging shell 5, and the hook 6 can be used to lift and hang the main line 1 for easy use.
[0037] The present invention also provides a curtain string light, wherein a plurality of circuit boards 2 are installed at intervals on the main line 1, and a plurality of lamps 3 are connected to the plurality of circuit boards 2. In this way, a plurality of lamps 3 are installed on the main line 1 to form a string light structure.
[0038] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
