DETAILED DESCRIPTION

[0026] The following is combined with Figures 1 to 9 The utility model is described in detail.

[0027] The utility model is a buckle-type waterproof LED lamp, comprising a bulb shell 1, a sealing plug 2, a waterproof socket 3 and a light-emitting assembly 4; the sealing plug 2 is assembled on the inner side of the mouth of the bulb shell 1, and the sealing plug 2 is provided with at least two wire holes 21; one end of the waterproof socket 3 is used to seal the outer side of the mouth of the bulb shell 1, and the other end is provided with a clamping tongue 31; the light-emitting assembly 4 is arranged inside the bulb shell 1, and the light-emitting assembly 4 at least comprises a first metal wire 41, a light-emitting lamp body 42 and a second metal wire 43 which are electrically connected in sequence, and the first metal wire 41 and the second metal wire 43 are electrically connected to each other. The other end of each of the two terminals passes through the wire hole 21 and is electrically connected to the waterproof socket 3. The waterproof socket 3 is provided with a first conductive plug post 32 and a second conductive plug post 33. The waterproof socket 3 also includes a wiring seat 5 and a fixing seat 6. The fixing seat 6 is provided on the wiring seat 5. The fixing seat 6 is provided with a plug slot 61. A buckle position 62 is provided inside the plug slot 61. The waterproof socket 3 is plugged into the plug slot 61 and the tongue 31 is snapped into the buckle position 62. The plug slot 61 is also provided with a hole position 63 adapted to the conductive plug post. The conductive plug post is plugged into the hole position 63 to realize the electrical connection of the lamp.

[0028] 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 a snap-on assembly of the lamp and the power cord, and adopts the electrical connection between the metal pin and the hole 63 inside. This assembly method saves a lot of metal raw materials and greatly reduces the preparation cost of the light string. The original metal material cost of about 0.6 yuan is only about 0.06 yuan after the improvement, and the cost is reduced by nearly ten times. At the same time, there is no need to over-mold a large-volume lamp holder, and the cost of plastic materials is also reduced. Secondly, the technical solution improves the waterproof performance of the bulb through the sealing plug 2, and also injects the waterproof socket 3 again on the outer side of the mouth of the bulb shell 1 to achieve secondary waterproofing of the lamp. After the waterproof socket 3 is formed, the mouth of the bulb shell 1 is completely sealed to achieve absolute waterproofing of the lamp. On the other hand, the lamp and the wiring socket 5 are assembled in a snap-on manner, which is not only firm but also convenient and efficient. The lamp can be disassembled and replaced, making the light string more flexible.

[0029] As another embodiment, Figure 2 As shown, a first power-carrying wire 7 is also included, and the wiring seat 5 is electrically connected to the fixing seat 6 via the first power-carrying wire 7. This embodiment can present a hanging decoration of the lamp, and when the lamp string is hung outdoors, the decorative effect is better.

[0030] When the socket does not include the second power wire 8, the first metal wire 41 and the second metal wire 43 pass through the wire hole 21 and directly extend out of the surface of the waterproof socket 3 to form a first conductive plug post 32 and a second conductive plug post 33 with a certain strength. At this time, the first conductive plug post 32 and the second conductive plug post 33 are part of the metal wire.

[0031] In the above embodiment, if Figure 6 As shown, the first metal wire 41 and the second metal wire 43 are both composed of a conductive wire 411 and a conductive column 412. The diameter of the conductive column 412 is larger than the diameter of the conductive wire 411. At this time, the first conductive plug-in column 32 and the second conductive plug-in column 33 are arranged at the end of the conductive column 412. This structure can ensure that the first metal wire 41 and the second metal wire 43 have sufficient strength to form a plug-in connection with the fixing seat 6, and can also save the raw materials of the metal wires, further reducing the production cost. Figure 6 As shown, the first metal wire and the second metal wire are further provided with a heat dissipation resistor 11.

[0032] like Figure 3 As shown, as another embodiment, the waterproof socket 3 further includes a second power wire 8, one end of the second power wire 8 is electrically connected to the waterproof socket 3, and the other end is electrically connected to the light-emitting assembly 4. This structure can also achieve the hanging effect of the lamp and enhance the decorativeness of the lamp.

[0033] Preferably, the second current conducting wire 8 is provided with a first positive wire 81 and a first negative wire 82, the first positive wire 81 is connected to the first metal wire 41 by butt welding; the first negative wire 82 is connected to the second metal wire 43 by butt welding, and then the mouth of the bulb 1 is injection-molded and sealed. Similarly, the electrical connection between the terminal block 5 and the main power line 9 is also made by butt welding. The butt welding method here refers to the direct heating and welding of the pole wire with another pole wire after tinning, without the need to coat the copper end. Compared with the traditional light string or lamp pole wire coated with copper terminal electrical connection, the pole wire is electrically connected by butt welding, which can further ensure that the pole wire is firmly connected to the lamp whether it is during secondary injection molding or in normal outdoor use, which can effectively prevent the lamp from having poor contact, and the cost is also lower.

[0034] In the present technical solution, the surface of the waterproof socket 3 is also provided with an isolation wall 34, and the fixing seat 6 is provided with an isolation groove 64 matched with the isolation wall 34. When the waterproof socket 3 is plugged into the fixing seat 6, the isolation wall 34 and the isolation groove 64 can be used to assist in precise positioning and installation, thereby improving assembly efficiency, and the isolation wall 34 isolates the positive and negative conductive plug posts to prevent the lamp from short-circuiting due to accidental contact between the electrodes. In the present technical solution, the isolation wall 34 is asymmetrically arranged on the waterproof socket 3, that is, the isolation wall 34 is at different lengths at both ends of the waterproof socket 3, so that the isolation wall 34 can also prevent the lamp electrodes from being mistakenly plugged in, thereby improving safety.

[0035] like Figure 1 and 3As shown, the light-emitting lamp body 42 of the present technical solution can be an LED light bar 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.

[0036] The utility model also includes a buckle-type waterproof light string, including the above-mentioned lamp, and also includes a main power line 9, a male plug 91 and a female socket 92; the male plug 91 and the female socket 92 are respectively arranged at both ends of the main power line 9; the wiring socket 5 is arranged in the middle of the main power line 9 and is electrically connected to the main power line 9. The light string of the present application is mainly used in outdoor gatherings, and has the advantages of the above-mentioned lamps such as low cost, high waterproof performance, simple structure, and fast assembly.

[0037] Preferably, the wiring socket 5 is provided with a hanging ear 51 for facilitating the hanging of the light string outdoors.

[0038] In order to improve the application range of the light string, the light string further includes a hook 10, and an elastic clamping portion 101 is provided at one end of the hook 10. When in use, the elastic clamping portion 101 can be clamped into the hanging ear 51 to form a Figure 8 The hanging structure of the light string shown. After the hanging ear 51 of the light string connector is used in conjunction with the hook 10, 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.

[0039] The above contents are only preferred embodiments of the present invention. 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.
