[0031] This utility model is a quick-positioning and assembly light string, including a power cord 1, one end of which is connected to a male plug 2 and the other end to a female socket 3, the male plug 2 being able to mate with the female socket 3; multiple lamps 4 are electrically connected to the middle of the power cord 1, each lamp 4 including a lamp holder 5 and a bulb 6 inserted into the lamp holder 5; the power cord 1 passes through the multiple lamp holders 5 in sequence, each lamp holder 5 being provided with at least two first conductors 51; the bulb 6 includes a lampshade 61, an insulating base 62, and a wick assembly 63, the lampshade 61 having an open end, the insulating base 62 being disposed outside the open end of the lampshade 61 and sealing the open end, the wick assembly 63 being disposed inside the lampshade 61, and the wick assembly 63 passing through the insulating base 62 being provided with at least two second conductors 64; the first conductors 51 and the second conductors 64 can be plugged into each other to electrically connect the lamp holder 5 and the bulb 6; it also includes an alignment device 7, used to limit the bulb 6 to be inserted and mated with the lamp holder 5 in a fixed position.

[0032] This application improves the structure by changing the threaded connection of the lamp 4 to a plug-in conductive method, thereby reducing the metal material used in the lamp 4 and significantly reducing the molding cost of a single lamp 4, which is more conducive to the production of the entire lamp string. Secondly, the lamp 4 is equipped with an alignment device 7 to guide the lamp holder 5 and the bulb 6 to be aligned and assembled, eliminating the traditional threaded connection steps and allowing for direct positioning and assembly. The assembly method is convenient, precise, and can effectively improve the assembly efficiency of the lamp 4. In addition, the lamp 4 has high water resistance. The opening of the lamp cover 61 is integrally injection molded with an insulating base 62, which completely isolates external moisture from the bulb 6 and effectively extends the service life of the lamp 4.

[0033] In this technical solution, the lamp core assembly 63 includes a sealing base 631 and a first metal conductor 632, a light source element 633, and a second metal conductor 634 that are electrically connected in sequence. The first metal conductor 632 and the second metal conductor 634 pass through the insulating base 62 and form two second conductors 64. The light source element 633 can be an LED strip, a lamp bead, or a T-shaped lamp board.

[0034] As an example, the lampshade 61 may also contain a number of fluorescent filaments 14, which are used to increase light refraction and make the bulb 6 highly decorative.

[0035] Preferably, the lamp holder 5 includes an integrally formed terminal block 52 and a connecting seat 53. The lamp holder 5 is connected to the power cord 1 via the terminal block 52, which is directly injection molded onto the outside of the power cord 1 to achieve a stable connection between the lamp holder 5 and the power cord 1.

In addition to being decorative, the longitudinal stripes also increase friction to facilitate gripping the lamp 4.

[0036] In this technical solution, the electrical connection between the lamp holder 5 and the bulb 6 can be implemented in various ways. One embodiment is as follows: Figure 2 As shown, the connector 53 is provided with at least two electrical sockets 8.

The second conductor 64 is a conductive plug-in post, and the second conductor 64 extends into the receiving position 65. The connector 53 can be inserted into the receiving position 65, so that the conductive plug-in post is inserted into the electrical socket 8 and electrically connected to the conductive terminal. In this embodiment, the lamp 4 is more suitable for hanging with the bulb 6 facing upwards, making it less likely for outdoor moisture to enter the lamp holder 5, which helps to extend the service life of the lamp 4.

[0037] To improve the connection strength between the lamp holder 5 and the bulb 6, based on the above structure, the outer wall of the connecting seat 53 is provided with an arc-shaped protrusion 9; the inner wall of the receiving position 65 is provided with a groove 10, and the arc-shaped protrusion 9 can be inserted into the groove 10, so that the bulb 6 is not easy to fall out of the lamp holder 5.

[0038] Preferably, the alignment device 7 includes an alignment post 71 disposed on the outer wall of the connecting seat 53 and a guide groove 72 disposed on the inner wall of the receiving position 65, wherein the alignment post 71 and the guide groove 72 are adapted to each other. This structure is simple and low-cost to achieve directional alignment and assembly of the lamp holder 5 and the bulb 6, thereby improving assembly efficiency.

[0039] As another embodiment, such as Figure 3As shown, this embodiment is a reverse insertion scheme of the above embodiment. The connector 53 has an insertion hole 54, the first conductor 51 is a conductive insertion post, and the first conductor 51 is disposed in the insertion hole 54; the outer end of the insulating base 62 is provided with a insertion base 66, the outer end face of the insertion base 66 is provided with at least two electrical insertion holes 8, the second conductor 64 is a conductive terminal, and the conductive terminal is installed in the electrical insertion hole 8; the insertion base 66 is inserted into the insertion hole 54, so that the conductive insertion post is inserted into the electrical insertion hole 8 and forms an electrical connection with the conductive terminal, thereby electrically assembling the bulb 6 and the lamp holder 5. The lamp 4 of this embodiment is more suitable for the bulb 6 to be suspended downwards, and even if suspended outdoors, moisture is not easily allowed to enter the lamp holder 5, thus improving safety.

[0040] Based on the above structure, the outer wall of the plug-in base 66 is provided with an arc-shaped protrusion 9; the inner wall of the plug-in hole 54 is provided with a groove 10, and the arc-shaped protrusion 9 can be inserted into the groove 10, thereby realizing the stable assembly of the lamp holder 5 and the bulb 6.

[0041] Similarly, the alignment device 7 includes an alignment post 71 disposed on the outer wall of the plug-in base 66 and a guide groove 72 disposed on the inner wall of the plug-in hole 54. The alignment post 71 and the guide groove 72 are adapted to realize the alignment and assembly of the lamp 4 and the lamp holder 5.

[0042] In this technical solution, the top of the terminal block 52 can be provided with a hanging ear 11; it also includes a hook 12, one end of which is provided with an elastic snap-fit ​​part 121, which can snap into the hanging ear 11, making it easier for the lamp 4 with the hook 12 installed to be hung outdoors.

[0043] To facilitate hanging the light string outdoors, the light string is also equipped with a mounting clip 13, such as... Figure 6 As shown, the mounting clip 13 includes a connecting main board 131. A plug-in plate 132 is provided on one side of the connecting main board 131, and a first clamping arm 133 and a second clamping arm 134 are provided on the other side. The first clamping arm 133 and the second clamping arm 134 are arranged opposite to each other and form a mounting position 135 for clamping and positioning the lamp holder 5 through a semi-circular portion. When in use, the lamp holder 5 is inserted into the mounting position 135, and the plug-in plate 132 can be inserted into the eaves, thus achieving outdoor positioning of the lamp 4. To facilitate fixing the mounting clip 13, a pressure strip 136 is also provided above the plug-in plate 132. The pressure strip 136 and the plug-in plate 132 form a clamping tendency. The cooperation between the pressure strip 136 and the plug-in plate 132 allows the mounting clip 13 to be not only inserted into the eaves for fixation but also clamped onto wooden strips, boards, etc., expanding its applicability.
