[0035] The following is a detailed explanation and description of the light strings and outdoor lights provided in this application, with reference to the accompanying drawings.

[0036] The light string provided in this application integrates the wire and the base shell into a single, sealed structure. During installation, conductive elements pierce the wires and establish an electrical connection with the circuit board. This eliminates the need for adhesive sealing between the wires and the shell during assembly, preventing any impact on product yield. Furthermore, the electrical connection between the wires and the circuit board is achieved during assembly, reducing the soldering process and simplifying the manufacturing process. Additionally, the circuit board and wires are separated at their respective positions on the base shell, with the electrical connection achieved through conductive elements passing through the wires, enhancing the sealing effect of the circuit board. The following detailed description, in conjunction with specific embodiments, further illustrates this application:

[0037] In some embodiments, this application provides a light string suitable for outdoor use, including multiple light heads and wires, with adjacent light heads electrically connected by wires, such as... Figure 1 As shown, the lamp holder includes a base shell 1, a circuit board 2, a lamp shade 3, and a conductive element 5. The circuit board 2 and the lamp shade 3 are mounted on the base shell 1. The circuit board 2 is sealed within the sealed space formed by the lamp shade 3 and the base shell 1. The wire 4 passes through the base shell 1, and the wire 4 forms a sealed contact with the base shell 1. The circuit board 2 and the wire 4 are electrically connected through the conductive element 5.

[0038] In some embodiments, the bottom shell 1 includes a bottom plate 11 and a bracket 12. The bracket 12 is disposed on the first surface of the bottom plate 11, and the circuit board 2 is disposed on the bracket 12, so that a gap is formed between the circuit board 2 and the bottom plate 1. The conductive element 5 is disposed in the gap, and the lampshade 3 is in sealed contact with the first surface of the bottom plate 11. The circuit board 2 is located inside the lampshade 3.

[0039] The wire 4 includes an insulation layer and a battery core. The insulation layer wraps around the battery core. In some embodiments, a portion of the wire 4 is integrally formed with the base plate 11 inside the base plate 11. The base shell 1 is integrally formed by injection molding, and during the injection molding process, a portion of the wire 4 is placed inside the base plate 11. During the molding process, a sealed connection can be formed between the insulation layer of the wire 4 and the base plate 11. The portion where the wire 4 is connected to the base plate 11 forms a sealed section, which is used for electrical connection with the conductive element 5. The conductive element 5 is made of conductive material and is located between the circuit board 2 and the base plate 11. A first connection end 51 is formed on the conductive element 5. The first connection end 51 is used to pass through the interior of the wire 4 and be electrically connected to the wire 4. A portion of the conductive element 5 is electrically connected to the circuit board 2, and the conductive element 5 enables the wire 4 to be electrically connected to the circuit board 2. Exemplarily, the first connection end 51 passing through the interior of the wire 4 includes the first connection end 51 piercing the insulation layer of the wire 4 to contact the battery core inside the wire 4, or it may also include the first connection end 51 completely penetrating the wire 4 and contacting the battery core.

[0040] like Figure 1 , Figure 2 As shown, in this application, a portion of the wire 4 is integrally formed inside the bottom shell 1. During the forming process, a seal can be achieved between the wire 4 and the bottom shell 1, eliminating the need for subsequent sealing of the connection between the wire 4 and the bottom shell 1. The electrical connection between the wire 4 and the circuit board 2 is completed through the conductive component 5, eliminating the need for welding between the wire 4 and the circuit board 2. This allows the electrical connection between the wire 4 and the circuit board 2 to be achieved during assembly, simplifying the overall manufacturing process of the product.

[0041] It is easily understood that the wire 4 and the base plate 11 can also be manufactured using a separate molding method. That is, a wire hole is provided on the base plate 11, the wire 4 passes through the wire control, and at least two sealing elements are provided between the wire 4 and the wire hole. The two sealing elements and the base plate 11 form a sealed cavity. The wire 4 located in the sealed cavity forms a sealed section for electrical connection with the conductive element 5. For example, the sealing element is a sealing ring, and sealing rings are provided at both ends of the wire hole. The sealing rings form a sealing contact with both the wire 4 and the wire hole. The separate molding method can reduce the manufacturing difficulty and make the base plate 11 and the wire 4 easier to process.

[0042] In some embodiments, such as Figure 3As shown, the conductive element 5 has a sheet-like structure and includes a first connecting end 51 and a second connecting end 52. The first connecting end 51 is used to penetrate the wire 4 and make an electrical connection with the wire 4, while the second connecting end 52 is used to make an electrical connection with the circuit board. Optionally, the first connecting end 51 is triangular to form a pointed tip. The sheet-like structure has a small thickness, making it easier to penetrate the insulation layer of the wire 4 and make contact with the battery core. The sheet-like structure can also increase the contact area between the first connecting end 51 and the battery core. In other embodiments, the first connecting end 51 can also be trapezoidal or similar, as long as it can easily penetrate the insulation layer of the wire 4. The second connecting end 52 of the conductive element 5 forms a bent section, which is perpendicular to the first connecting end 51. The second connecting end 52 contacts the circuit board 2 and makes an electrical connection. The bent section can increase the contact area with the circuit board 2, making the conductive connection more reliable. In other embodiments, the conductive element 5 can also be needle-like or other similar shapes, with a pointed tip that can penetrate the wire 4 and make contact with the circuit board 2. The following embodiment uses a sheet-like structure for the conductive element 5 as an example.

[0043] In some embodiments, such as Figure 2 As shown, the base plate 11 is a flat plate structure, and the support 12 is a ring-shaped structure. Optionally, the support 12 can be configured as an ellipse, rectangle, or other ring shape, as long as it can provide support for the circuit board 2. The circuit board 2 is supported by the support 12, so that there is a certain gap between it and the first surface of the base plate 11. Optionally, the circuit board 2 is parallel to the base plate 11. In other embodiments, the support 12 may also include multiple independent support parts, that is, the support 12 does not form a ring-shaped structure. The structure of the support 12 is not specifically limited, as long as it can provide support for the circuit board 2 and form a gap between the circuit board 2 and the base plate 11 to provide space for the installation of the conductive component 5.

[0044] Optionally, such as Figure 2 As shown, the bracket 12 is also provided with a fixing structure 121, which fixes the circuit board 2 to the bracket 12. In some embodiments, the fixing structure 121 is a locking tooth, which engages with the edge of the circuit board 2 to fix its position when the circuit board 2 is installed on the bracket 12. Further, the bracket 12 is also provided with a positioning block 122. Correspondingly, a positioning hole can be provided on the circuit board 2. During installation, the positioning block 122 is embedded in the positioning hole. The positioning block 122 and the positioning hole limit the circuit board 2 in the direction parallel to the base plate 11, and the locking tooth limits the circuit board 2 in the direction perpendicular to the base plate 11 to effectively fix the circuit board 2. In other embodiments, the circuit board 2 can also be fixed by a combination of a slot and a locking tooth. For example, a slot can be provided on the bracket 12, the circuit board 2 can be embedded in the slot, and the locking tooth engages with the edge of the circuit board 2 to restrict the circuit board 2 within the slot, thus completing the fixation of the circuit board 2.

[0045] In some embodiments, such as Figure 2 As shown, a through hole 111 is formed on the first surface of the base plate 11 for the first connecting end 51 to pass through. The through hole 111 is located in the area distributed by the bracket 12. A portion of the sealed section of the wire 4 can be exposed through the through hole 111. The first connecting end 51 of the conductive element 5 passes through the through hole 111 and pierces the insulation layer of the wire 4 to penetrate into the wire 4 and make contact with the battery core to achieve electrical connection. The through hole 111 plays a positioning role in the installation of the conductive element 5, so that it can accurately achieve electrical connection with the wire 4. At the same time, it also allows the conductive element 5 to only need to pierce the insulation layer of the wire 4 to achieve electrical connection with the battery core of the wire 4. In other embodiments, the through hole 111 may not be provided, so that the distance between the wire 4 and the first surface of the base shell 1 is closer, that is, the thickness of the portion of the wire 4 covering the first surface of the base shell 1 is thinner, so that the first connecting end 51 of the conductive element 5 can be pierced.

[0046] In some embodiments, such as Figure 1 As shown, the lamp holder also includes a mounting base 6, on which the conductive element 5 is fixed. The mounting base 6 is installed on the first surface of the base plate 11, allowing the first connecting end 51 of the conductive element 5 to be inserted into the wire 4 during installation. Optionally, the mounting base 6 is connected to the base plate 11 by means of screws, snap-fit ​​connections, or adhesive bonding.

[0047] Optionally, the fixing base 6 has a rectangular block structure with an inner groove formed on its bottom surface. The bottom surface contacts the first surface of the base plate 11. The first connecting end 51 of the conductive element 5 extends out from the inner groove. When the bottom surface of the fixing base 6 contacts the first surface of the base plate 11, the first connecting end 51 of the conductive element 5 is precisely inserted into the wire 4 and contacts the battery core. The second connecting end 52 of the conductive element 5 passes through the top surface of the fixing base 6 and is bent to form a bent section that fits against the top surface of the fixing base 6, facilitating electrical connection with the circuit board 2. The circuit board 2 is provided with an electrical connection part 21, which makes conductive contact with the conductive element 5, that is, the electrical connection part 21 makes conductive contact with the second connecting end 52 of the conductive element 5. Optionally, the electrical connection part 21 is a spring pin or a spring sheet, which can press the electrical connection part 21 tightly onto the second connecting end 52 of the conductive element 5 through elastic force, ensuring the reliability of the electrical connection between the two. In other embodiments, the conductive element 5 is fixedly connected to the circuit board 2, that is, the second connection end 52 is fixedly connected to the circuit board 2, and the first connection end 51 of the conductive element 5 is away from the circuit board 2. In this way, the fixing base 6 is not required, and the conductive element 5 can be installed together with the circuit board 2.

[0048] In some embodiments, such as Figure 1 As described, LED beads 22 are disposed on the circuit board 2, and the LED beads 22 are attached to the circuit board 2 to form an integral part of the circuit board 2. The LED beads 22 can emit light colors as needed. Optionally, such as Figure 4As shown, the lampshade 3 includes a side plate 31 and a top plate 32. The side plate 31 has a ring-shaped structure, and the top plate 32 is located at the first end of the side plate 31. The second end of the side plate 31 is sealed and pressed against the first surface of the base plate 11. A lens 33 is provided on the top plate 32, and the lens 33 is correspondingly arranged with the LED beads 22. The light emitted by the LED beads 22 is emitted through the lens 33. The combination of the lens 33 and the LED beads 22 can limit the light angle, making the function and application scenarios of the light string more diverse. Optionally, multiple LED beads 22 can be provided, such as two or more, and each LED bead 22 is provided with a lens 33. Different lenses 33 have different thicknesses or curvatures, so that the light emitted by different LED beads 22 can be different.

[0049] Optionally, such as Figure 1 , Figure 7 As shown, a sealing ring 7 is provided between the second end of the side plate 31 of the lampshade 3 and the first surface of the base plate 11 to form a sealed contact between the lampshade 3 and the base plate 11, thereby sealing the circuit board 2 and the conductive parts 5 inside the lampshade 3, without the need for additional sealing treatment or sealing structure.

[0050] In some embodiments, such as Figure 2 As shown, the bottom shell 1 also includes a connecting plate 13, which is disposed on the first surface of the bottom plate 11 for connection with the lampshade 3. Optionally, the connecting plate 13 forms an annular structure around the bracket 12, and a sealing ring 7 is disposed between the bracket 12 and the connecting plate 13. The sealing ring 7 can be limited by the connecting plate 13 and the bracket 12 to prevent displacement of the sealing ring 7 during installation. A first buckle 131 is formed on the connecting plate 13, and a second buckle 34 is provided on the outer wall of the side plate 31. At least a portion of the side plate 31 extends into the connecting plate 13, and the second buckle 34 engages with the first buckle 131. In other embodiments, the connecting plate 13 may also form a multi-segment structure that is independent of each other around the bracket 12, with a first buckle 131 provided on each segment.

[0051] In some embodiments, such as Figure 5 , Figure 6 , Figure 7As shown, the lamp holder also includes a housing 8, which covers the outside of the lampshade 3 and is connected to the connecting plate 13. The housing 8 is dome-shaped, with an opening 81 formed on its top wall. The lens 33 of the lampshade 3 can extend to the outside of the housing 8 through a snap-fit ​​hole. Each lens 33 corresponds to one opening 81, and the shape of the opening 81 corresponds to the lens 33, so that the edge of the opening 81 contacts the edge of the lens 33. The housing 8 covers the side plate 31 and part of the top plate 32 of the lampshade 3, while exposing the transparent part, which can provide a certain degree of protection for the lampshade 3. Optionally, a third snap 132 is provided on the outer wall of the connecting plate 13, and a fourth snap 82 is provided on the inner wall of the housing 8. The third snap 132 and the fourth snap 82 engage to complete the connection between the housing 8 and the bottom shell 1. Optionally, a fifth buckle 112 can be provided on the base plate 11, and a sixth buckle 83 can be provided on the inner wall of the outer shell 8. The fifth buckle 112 and the sixth buckle 83 are engaged to achieve a double connection between the outer shell 8 and the base shell 1, thereby improving the reliability of the connection.
