[0032] See also Figures 1 to 7 In the specific embodiment shown, the utility model discloses a string light structure, including: a bulb component 10, a lamp holder 20, a wire 30 and a lamp cover 40, wherein the lamp holder 20 is provided with a positive spring piece 50 and a negative spring piece 60, the bulb component 10 is movably connected to the lamp holder 20, and is electrically connected to the positive spring piece 50 and the negative spring piece 60, the wire 30 is transversely passed through the lamp holder 20, and abuts against the positive spring piece 50 and the negative spring piece 60, and the lamp cover 40 is movably connected to the lamp holder 20; when the lamp cover 40 is pressed against the lamp holder 20, the lamp cover 40 squeezes the wire 30 so that the positive spring piece 50 and the negative spring piece 60 pierce the wire 30 to form a conductive state.

[0033] Specifically, the positive spring clip 50 is used to connect the live wire, and the negative spring clip 60 is used to connect the neutral wire. The traditional lamp cover 40 and the lamp holder 20 are combined together, which requires a welding process. This string light structure uses the lamp cover 40 to press the wire 30, so that the positive spring clip 50 and the negative spring clip 60 pierce the wire 30, thereby directly forming a conductive state. This method realizes a welding-free process, significantly simplifies the production process, improves overall production efficiency, reduces production costs, and is highly practical. In addition, welding not only requires specific equipment and materials, but may also require skilled workers to operate, all of which increase production costs. This technology reduces these additional costs by simplifying the production process, thereby reducing production costs.

[0034] See also Figures 2 to 5 As shown, in one embodiment, the tops of the positive electrode spring piece 50 and the negative electrode spring piece 60 are both provided with sharp protrusions 51 for piercing the wire 30 .

[0035] Specifically, the spike protrusions 51 of the positive spring clip 50 and the negative spring clip 60 are staggered, that is, one on the left and the other on the right. When the lamp cover 40 squeezes the wire 30, the positive spring clip 50 and the negative spring clip 60 pierce the outer skin of the wire 30 and form effective contact with the wire inside the wire 30, that is, form a conductive state. In other words, the staggered distribution of the spike protrusions 51 (one on the left and the other on the right) ensures that the positive spring clip 50 and the negative spring clip 60 can pierce different parts of the wire 30 respectively, thereby avoiding short circuits and ensuring correct electrical connections. This design increases the reliability and safety of the connection. In addition, due to the design of the spike protrusions 51, when the lamp cover 40 squeezes the wire 30, they can quickly and effectively pierce the outer skin of the wire 30, forming a conductive state, improving the efficiency of the connection, and reducing possible failures during the connection process. In addition, the design of the spiked protrusion 51 is also adaptable to a certain extent and can cope with the outer skin of the wire 30 of different thicknesses and materials. This flexibility enables the technology to be applied to a wider range of scenarios and product lines.

[0036] See also Figures 2 to 6 As shown, in one embodiment, the lamp holder 20 is provided with a first placement cavity 21 and a second placement cavity 22 . The first placement cavity 21 is used to install the positive electrode spring piece 50 , and the second placement cavity 22 is used to install the negative electrode spring piece 60 .

[0037] Specifically, by providing the first placement cavity 21 and the second placement cavity 22, the installation positions of the positive and negative spring clips 50 and 60 can be clearly distinguished, avoiding confusion and incorrect installation. Furthermore, these two placement cavities provide a stable installation environment for the positive and negative spring clips 50 and 60, ensuring they are properly connected to the wire 30 and the bulb assembly 10, thereby completing the circuit and illuminating the light. Furthermore, the placement cavity design makes the installation of the positive and negative spring clips 50 and 60 simple and quick, eliminating the need for complex operations or tools, thereby reducing assembly difficulty and cost.

[0038] See also Figures 3 to 6 As shown, in one embodiment, the first placement cavity 21 is provided with a first clamping groove 211 for fixing the positive electrode spring sheet 50 , and the second placement cavity 22 is provided with a second clamping groove 221 for fixing the negative electrode spring sheet 60 .

[0039] Specifically, the design of the first snap-in groove 211 and the second snap-in groove 221 enables the positive and negative spring clips 50 and 60 to be precisely positioned at predetermined positions during installation, thus avoiding displacement or misalignment during the installation process. In addition, through the fixing effect of the snap-in groove, the positive and negative spring clips 50 and 60 can be firmly fixed in the placement cavity, preventing them from loosening or falling off during use, thereby ensuring the stability and safety of the circuit. In addition, the contact between the fixed spring clips and the wire 30 is more stable, reducing circuit failures caused by poor contact, such as flickering or non-lighting of the bulb. In addition, the firm fixing method can reduce deformation or damage of the spring clips due to uneven force during use, thereby extending the service life of the lamp. In addition, the design of the snap-in groove makes the installation of the positive and negative spring clips 50 and 60 simpler and faster, without the need for additional fixing tools or steps, reducing the difficulty and cost of assembly.

[0040] See also Figures 2 to 6 As shown, in one embodiment, the lamp holder 20 is further provided with a limiting protrusion 23 , and the limiting protrusion 23 is matched with the wire 30 .

[0041] Specifically, the intermediate position between the limiting protrusion 23 and the wire 30 forms a limiting state, so that the wire 30 can only move along the cross-sectional direction of the wire 30. In other words, the design of the limiting protrusion 23 ensures that the wire 30 can be stably fixed in the lamp holder 20 during installation, preventing the wire 30 from shaking or moving. This stability is crucial for ensuring the normal connection of the circuit and preventing circuit failures caused by loose wire 30. In addition, the cooperation between the limiting protrusion 23 and the wire 30 can ensure a tighter and more stable connection between the wire 30 and the positive and negative spring clips 50 and 60. This tight connection helps reduce the risk of poor contact and circuit failure, thereby improving the reliability and stability of the entire circuit.

[0042] See also Figures 2 to 6 As shown, in one embodiment, connecting blocks 41 are provided on both sides of the bottom of the lamp cover 40 , and the lamp holder 20 is provided with protrusions 24 corresponding to the connecting blocks 41 .

[0043] Specifically, the connection between the connecting block 41 and the raised portion 24 allows the lamp cover 40 and the lamp holder 20 to be easily connected without requiring complex installation steps or tools, thus reducing installation difficulty and cost. Furthermore, the design of the connecting block 41 and the raised portion 24 generally provides a tight fit, ensuring a secure and reliable connection between the lamp cover 40 and the lamp holder 20, thereby preventing circuit failures or safety hazards caused by a loose connection.

[0044] See also Figures 2 to 6As shown, in one embodiment, a snap-fit ​​protrusion 411 is provided at the lower end of the connecting block 41 , and the snap-fit ​​protrusion 411 is engaged with the protruding portion 24 .

[0045] Specifically, the matching design of the snap-fit ​​protrusion 411 and the raised portion 24 can make the connection between the connecting block 41 and the lamp holder 20 tighter and more stable. This tight connection helps prevent the lamp cover 40 from loosening or falling off due to force during use, thereby improving the overall stability and safety of the lamp. In addition, through the matching of the snap-fit ​​protrusion 411 and the raised portion 24, the user can more easily install and remove the lamp cover 40 from the lamp holder 20. This design does not require additional fixing tools or steps, reduces the complexity and cost of installation, and also improves the convenience of maintenance. In addition, the design of the snap-fit ​​protrusion 411 can also make it easier to align and position the lamp cover 40 during installation. The correct position of the lamp cover 40 can be quickly determined by matching the snap-fit ​​protrusion 411 with the raised portion 24, thereby simplifying the installation process and improving the accuracy of installation.

[0046] See also Figures 2 to 5 As shown, in one embodiment, the lamp cover 40 is further provided with a limiting groove 42 corresponding to the wire 30 .

[0047] Specifically, the design of the retaining groove 42 can accurately fix the position of the wire 30, preventing it from shifting during installation or use. This stability ensures that the spike protrusion 51 can accurately pierce the outer skin of the wire 30 and form effective contact with the wire inside the wire 30. This contact is key to circuit conduction, ensuring the stable flow of current in the circuit and avoiding poor contact or circuit failure caused by the displacement of the wire 30. In addition, through the cooperation of the retaining groove 42 and the spike protrusion 51, the connection between the wire 30 and the spring can be achieved without complicated operations or additional fixing steps. This design reduces the difficulty and complexity of installation and improves installation efficiency. In addition, after the spike protrusion 51 pierces the outer skin of the wire 30, it forms a close contact with the wire inside the wire 30. This contact method has high stability and durability, can withstand certain current and voltage fluctuations, and is not prone to poor contact or circuit failure caused by long-term use or environmental factors.

[0048] See also Figures 2 to 4 As shown, in one embodiment, the lamp cover 40 is further provided with a hook portion 43 .

[0049] Specifically, the design of the hook portion 43 enables the lamp cover 40 to be easily connected to an external structure (such as a ceiling, wall, or other suspension device), thereby simplifying the installation process of the string lights. The user can quickly complete the installation of the string lights without using complex tools or performing tedious steps. At the same time, the hook portion 43 is also convenient for the user to disassemble when necessary, facilitating replacement or maintenance. In addition, the design of the hook portion 43 has a certain versatility and can adapt to a variety of different hanging environments. Whether it is a ceiling, wall, or other suspension device, the hook portion 43 can provide a reliable connection point, which allows the string lights to be flexibly used in various occasions, such as home decoration, commercial displays, festival celebrations, etc.

[0050] See also Figures 3 to 5 As shown, in one embodiment, the inner wall of the lamp holder 20 is provided with a threaded portion 25 , and the threaded portion 25 is matched with the bulb component 10 .

[0051] Specifically, threaded connection is a very stable connection method. When the bulb component 10 is tightly combined with the threaded portion 25 in the lamp holder 20 by rotation, a very strong connection point can be formed. This connection method can effectively prevent the bulb component 10 from loosening or falling off due to vibration, wind or other external forces during use, thereby ensuring the stability and safety of the lamp. In addition, the design of the threaded connection makes the installation and disassembly of the bulb component 10 very simple. The user only needs to rotate the bulb component 10 to connect or separate it from the lamp holder 20 without the use of additional tools or complicated steps. This design not only improves the convenience of installation, but also reduces maintenance costs. In addition, the design of the threaded portion 25 has a certain degree of versatility and can adapt to bulb components 10 of various specifications. This allows the same lamp holder 20 to be adapted to a variety of different lamps, thereby improving the compatibility and flexibility of the product.

[0052] See also Figure 7 As shown, the string light structure can be used alone or in combination with several lights to form a light strip string, with adjacent string lights sharing the same wire 30 .

[0053] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
