DETAILED DESCRIPTION

[0025] The following is combined with Figures 1 to 8 The utility model is described in detail.

A second metal wire 33, the other ends of the first metal wire 31 and the second metal wire 33 both extend through the wire hole 21 into the plug-in slot 42 to form a first conductive plug-in column 34 and a second conductive plug-in column 35; it also includes a branch power line 5, the branch power line 5 is provided with an electrical connection seat 51, and the branch power line 5 is movably sleeved with a threaded cap 52, the electrical connection seat 51 can be plugged into the plug-in slot 42, and the electrical connection seat 51 is provided with a plug-in hole 511 adapted to the conductive plug-in column; the inner wall of the threaded cap 52 is provided with an internal threaded portion, and the threaded cap 52 is threadedly connected to the waterproof threaded seat 4 through the internal threaded portion.

[0027] The utility model improves the connection method between the lamp and the power cord, and improves the traditional lamp electrical connection method through metal threaded lamp holder and metal copper sleeve into plug-in assembly of the lamp and the power cord. This assembly method saves a lot of metal raw materials and greatly reduces the preparation cost of the light string. The metal material cost that originally required about 0.6 yuan is only about 0.06 yuan after the improvement. At the same time, there is no need for rubber-coated large-volume lamp holder, and the cost of plastic materials is also reduced. Secondly, the technical scheme improves the waterproof performance of the bulb through the waterproof rubber seat 2, and injects the waterproof threaded seat 4 again on the outside of the mouth of the lampshade 1 to achieve secondary waterproofing of the lamp. After the waterproof threaded seat 4 is formed, the mouth of the lampshade 1 is completely sealed to achieve absolute waterproofing of the lamp. On the other hand, after the lamp is electrically plugged into the branch power cord 5, it is threadedly fixed and assembled through the external threaded cap 52. The assembly is firm and convenient, and the lamp can be disassembled and replaced, which makes the light string more flexible.

[0028] like Figure 1 and 2 As shown, the light source 32 of the present technical solution can be an LED light strip or an LED lamp bead. During production, the light-emitting element can be arbitrarily selected according to the use requirements, and the LED lamp bead can also be a controllable seven-color lamp bead.

[0029] In order to improve the plug-in efficiency of the waterproof threaded seat 4 and the branch power line 5, the plug-in slot 42 is provided with a positioning block 421, and the electrical connection seat 51 is provided with a positioning slot 512 adapted to the positioning block 421. When assembling the lamp, the positioning slot 512 of the electrical connection seat 51 is aligned with the positioning block 421 for assembly, and the efficiency can be significantly improved whether it is manual assembly or automatic assembly.

[0030] Preferably, the first metal wire 31 and the second metal wire 33 are composed of two parts: a conductive wire 311 and a conductive column 312, wherein the diameter of the conductive column 312 is larger than the diameter of the conductive wire 311, the conductive wire 311 is electrically connected to the light source 32, and the conductive column 312 passes through the waterproof rubber seat 2 and extends into the plug-in slot 42, and the ends of the conductive column 312 form a first conductive plug-in column 34 and a second conductive plug-in column 35 with relatively high strength, which are used to be plugged into the electrical connection seat 51. This structure can not only ensure that the first metal wire 31 and the second metal wire 33 have sufficient strength to be plugged into the electrical connection seat 51, but also save the raw materials of the metal wire, further reducing the production cost. Among them, Figure 4 As shown, the first metal wire and the second metal wire are further provided with a heat dissipation resistor 9.

[0031] As an embodiment, the electrical connection seat 51 includes an assembly portion 513 and a plug-in portion 514, and the plug-in portion 514 is plugged into the plug-in slot 42; a platform portion 515 is provided between the assembly portion 513 and the plug-in portion 514 for sealing the open end of the plug-in slot 42 to prevent external moisture from entering the interior of the plug-in slot 42.

[0032] To further improve the waterproof performance, a sealing ring 516 is further provided above the platform portion 515. When the electrical connection seat 51 is inserted into the insertion slot 42, the sealing ring 516 is squeezed, and the sealing ring 516 is deformed to further seal the connection gap between the electrical connection seat 51 and the waterproof threaded seat 4.

[0033] Preferably, a plurality of fluorescent filaments 11 are placed inside the lampshade 1, and the fluorescent filaments 11 are colorful. When the light source 32 emits light, the fluorescent filaments 11 can reflect part of the light source, and the reflection is in different directions, increasing the change of light, thereby improving the user's visual experience and optimizing the decorative effect of the lamp.

[0034] The utility model also includes a highly waterproof light string, including the above-mentioned multiple lamps, and also includes a main power line 6, a male plug 61, a female socket 62 and multiple light string connectors 7; the male plug 61 and the female socket 62 are respectively arranged at both ends of the main power line 6, which is convenient for the electrical connection between the light string and the external power supply or the electrical connection between the light strings; the multiple light string connectors 7 are evenly distributed in the middle of the main power line 6; the branch power line 5 extends into the interior of the light string connector 7 and is electrically connected to the main power line 6. The light string of the present application is mainly used in outdoor party decoration, and has all the advantages of the above-mentioned lamps such as low cost and high waterproof performance.

[0035] Preferably, the light string connector 7 is provided with a hanging ear 71 for facilitating the light string to be hung outdoors.

[0036] In order to improve the application range of the light string, the light string further includes a hook 8, one end of which is provided with an elastic clamping portion 81. When in use, the elastic clamping portion 81 can be clamped into the hanging ear 71 to form a Figure 7 The hanging structure of the light string shown. After the hanging ear 71 of the light string connector 7 is used in conjunction with the hook 8, it is transformed into another form of hanging structure, so that the light string is applicable to more outdoor scenes and has a wider range of applications.

[0037] Preferably, the branch power line 5 includes at least a first positive line 53 and a first negative line 54; the main power line 6 includes at least a second positive line 63 and a second negative line 64; the first positive line 53 is electrically connected to the second positive line 63 by welding, and the first negative line 54 is electrically connected to the second negative line 64 by welding. Compared with the traditional copper terminal-wrapped electrical connection between the pole line of the light string line and the lamp, the pole line is electrically connected to the light string line by welding, which can further ensure that the pole line is firmly connected to the lamp whether it is during the second injection molding of the light string connector 7 or during normal outdoor use, and can effectively prevent the lamp from having poor contact.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
