Description

Technical Field

[0001] The utility model relates to the technical field of decorative lighting, in particular to a decorative lamp and a lamp string. Background Art

[0002] Decorative light strings are an important element in creating a festive atmosphere. They are also often used for lighting and decoration of outdoor landscapes, such as parks, squares, commercial streets, and residential areas, to attract tourists and residents to stop and watch, and enhance the night image of the city or region.

[0003] Decorative lights in the prior art primarily include a bulb assembly and a bulb mounted to a standard base. For example, the bulb can be mounted to a screw base configured to be threadedly connected to a complementary bulb socket or a bayonet base configured to be bayonet-connected to a complementary bulb socket. The base includes a shell that defines the negative terminal of the bulb assembly. The base also includes the positive terminal of the bulb assembly. When the shell is connected to the bulb socket, the negative and positive terminals provided by the shell mate with the respective negative and positive terminals of the bulb socket to electrically connect the bulb assembly to the bulb socket, thereby powering the wick and emitting light. However, this threaded connection can result in unstable connections. Utility Model Content

[0004] In order to overcome the deficiencies in the prior art, the utility model provides a decorative lamp and a lamp string, which have the advantages of more stable connection and the like.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A decorative lamp comprises a filament body, a wire and an electrical connector for establishing an electrical connection between the two. The decorative lamp also comprises an insulating connector injection-molded on and wrapping the electrical connector, and part of the wire is wrapped by the insulating connector.

[0007] With the aforementioned technical solution, since the insulating connector is directly embedded in the electrical connector through injection molding, it achieves all-round wrapping of the electrical connector, reducing possible gaps. This seamless wrapping can more effectively reduce moisture penetration, thereby improving the waterproof performance of the decorative lamp for outdoor use. The injection molding process enables the insulating connector to more tightly integrate the electrical connector and the wire during the molding process, enhancing the contact tightness between the wire and the electrical connector and reducing the risk of poor contact. Further, by wrapping part of the wire in the insulating connector, the support of the wire is increased, and the ability of the wire to resist external tension is improved. When pulled by external forces, the wire is less likely to be damaged, thereby protecting the integrity of the decorative lamp when it is powered on.

[0008] Furthermore, it also includes a lampshade and a connecting piece, the connecting piece is interference fit with the insulating connector, and the lampshade head is threadedly connected to the connecting piece.

[0009] The aforementioned technical solution employs an interference fit between the connector and the insulating connector, requiring the connector to overcome a certain resistance during assembly to securely engage the insulating connector. This ensures that the two components are not easily loosened after connection, provides stable support, and reduces the risk of loosening due to vibration or external forces. The lampshade head and connector utilize a threaded connection for removable installation. By rotating the lampshade head, the lampshade can be easily installed and removed, facilitating subsequent maintenance and replacement.

[0010] Furthermore, a connecting ring groove is provided on the outer periphery of the insulating connector, and a clamping portion that is clamped and matched with the connecting ring groove is provided on the connector.

[0011] By adopting the above-mentioned technical solution, when the snap-fit portion on the connector is inserted into the connecting ring groove of the insulating connector, a stable connection is formed between the two, which can resist external pulling force, prevent relative movement between the connector and the insulating connector, increase stability, and also reduce the risk of the connector falling off the insulating connector when subjected to a large external force.

[0012] Furthermore, the outer diameter of the insulating connector at one end close to the filament body is smaller than the inner diameter of the clamping ring, the outer diameter of the insulating connector at one end away from the filament body is larger than the inner diameter of the clamping portion, and the connecting ring groove is provided at the end away from the filament body.

[0013] By adopting the above-mentioned technical solution, the outer diameter of the insulating connector gradually decreases from the end away from the filament to the end close to the filament, so that during the installation process, the connector and the lampshade can be naturally connected along the insulating connector, which plays a good guiding role, reduces the difficulty of installation, and improves the installation efficiency. When the connector completely passes through the insulating connector and reaches the predetermined position, the clamping part of the connector is completely clamped into the connecting ring groove.

[0014] Furthermore, it also includes a lamp holder for hanging decorative lamps, wherein a fixing groove is provided in the lamp holder, and the insulating connector is provided with a fixing portion plugged into the fixing groove.

[0015] By adopting the above-mentioned technical solution, the decorative lamp can be firmly hung on the lamp head through the tight connection between the fixing part and the fixing groove, and is not easily shaken or fallen off due to external force, thereby improving the safety of the decorative lamp. The plug-in design simplifies the installation process of the decorative lamp, and the installation can be completed without the use of additional tools or complicated operations, thereby improving the installation efficiency and reducing the installation difficulty.

[0016] Furthermore, two avoidance holes are arranged opposite to each other on the lamp holder, and the wires include a first wire and a second wire, and the first wire and the second wire respectively pass through one of the avoidance holes.

[0017] By adopting the above technical solution, the first wire and the second wire are allowed to pass through the avoidance hole.

[0018] Furthermore, an avoidance groove is formed between the outer periphery of the fixing groove and the avoidance hole, and the avoidance groove is communicated with the avoidance hole.

[0019] By adopting the above-mentioned technical solution, the avoidance groove allows the wire to pass through the avoidance hole smoothly, while also reducing the material used in the lamp holder, saving material costs, and reducing the weight of the entire lamp holder, thereby improving overall stability.

[0020] Furthermore, the lamp holder is provided with a hook and a limiting member connected to the hook, one end of the limiting member is connected to the lower end of the hook opening, and the other end is arranged higher than the upper end of the opening and forms a wire inlet between the upper end of the opening.

[0021] By adopting the above-mentioned technical solution, when the decorative lamp is hung on a wall or other location through a hook, the limiting member will form a barrier at the opening of the hook, which can effectively prevent the decorative lamp from falling from the wall or other location when subjected to external forces (such as wind, vibration, etc.) and causing damage. One end of the limiting member is connected to the lower end of the hook opening, and the other end is set higher than the upper end of the opening and forms a wire entry hole with the hook, which can improve the stability and safety of the suspension to a certain extent.

[0022] Furthermore, chamfered surfaces are provided on both sides of the insulating connector to form avoidance surfaces on both sides. The avoidance surfaces are inclined from away from the filament body to close to the filament body and gradually shrink the insulating connector.

[0023] By adopting the above-mentioned technical solution, the beveled surface forms avoidance surfaces on both sides of the insulating connector, which provides better guiding effect when the connector and the lampshade are connected. At the same time, the beveled surface reduces the use of materials while maintaining the functionality of the insulating connector, thereby reducing production costs.

[0024] A decorative lamp string comprises a main cable and the above-mentioned decorative lamps, wherein a plurality of the decorative lamps are connected in parallel and / or in series to the main cable.

[0025] By adopting the above technical solution, multiple decorative lights are strung together into a decorative light string, which is more beautiful, can adapt to the needs of different occasions, and has a wider range of applications. The light string wires themselves have a certain connection strength and no longer require additional support. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 and Figure 2 As shown, a decorative lamp 1 includes a filament body 11, a wire 12 and an electrical connector 131 for establishing an electrical connection between the two. The decorative lamp 1 also includes an insulating connector 13 injection-molded on the electrical connector 131 and wrapping the electrical connector, and part of the wire 12 is wrapped by the insulating connector 13.

[0031] It is understandable that since the insulating connector 13 is directly embedded in the electrical connector 131 through injection molding, it achieves all-round wrapping of the electrical connector 131, reducing possible gaps. This seamless wrapping can more effectively reduce moisture penetration, thereby improving the waterproof performance of the decorative lamp 1 when used outdoors. The injection molding process enables the insulating connector 13 to more tightly combine the electrical connector 131 and the wire 12 during the molding process, thereby enhancing the contact tightness between the wire 12 and the electrical connector 131 and reducing the risk of poor contact. Further, by wrapping part of the wire 12 in the insulating connector 13, the support for the wire 12 is increased, and the ability of the wire 12 to resist external tension is improved. When pulled by external force, the wire 12 is less likely to be damaged, thereby protecting the integrity of the decorative lamp 1 when it is powered on.

[0032] In this embodiment, the electrical connector 131 is a PCB board, and a wire 12 is connected between the filament body 11 and the positive and negative poles of the power supply of the decorative lamp 1, and the electrical connection is achieved through the PCB board. The wire 12 has a certain hardness and can provide additional support for the overall circuit, effectively preventing the risk of poor contact or short circuit caused by vibration or external force. In terms of insulation protection, the insulating connector 13 can be made of black rubber material, which not only has good insulation performance, but can also effectively isolate current and prevent the occurrence of leakage.

[0033] In another embodiment, the positive and negative electrodes of the filament can be electrically connected to the wires through the terminal blocks, or directly connected to the wires. In this case, the terminal blocks or the connection points between the filament and the wires form an electrical connector.

[0034] Further on the basis of the above, the decorative lamp 1 further includes a lampshade 14 and a connector 15 . The connector 15 is interference-fitted with the insulating connector 13 , and the lampshade head 141 is threadedly connected to the connector 15 .

[0035] It is understood that the interference fit between connector 15 and insulating connector 13 requires a certain amount of resistance to be overcome during assembly in order for connector 15 to be tightly coupled with insulating connector 13. This ensures that the two are not easily loosened after connection, provides stable support, and reduces the risk of loosening due to vibration or external forces. The lampshade head 141 and connector 15 are threaded for removable installation. By rotating the lampshade head 141, the lampshade 14 can be easily installed and removed, facilitating subsequent maintenance and replacement.

[0036] Optionally, the lampshade 14 is generally made of heat-resistant glass, and different colors of lampshades 14 can be selected according to the needs of different scenarios; the connector 15 is made of metal in this embodiment, and the connector 15 is used to install the lampshade 14 on the insulating connector 13.

[0037] Preferably, a connecting ring groove 132 is provided on the outer periphery of the insulating connector 13 , and a clamping portion 151 that is clamped and matched with the connecting ring groove 132 is provided on the connector 15 .

[0038] It can be understood that when the snap-fit portion 151 on the connector 15 is snapped into the connecting ring groove 132 of the insulating connector 13, a stable connection is formed between the two, which can resist external pulling force, prevent relative movement between the connector 15 and the insulating connector 13, increase stability, and also reduce the risk of the connector 15 falling off the insulating connector 13 when subjected to a large external force.

[0039] Preferably, the outer diameter of the insulating connector 13 at the end close to the filament body 11 is smaller than the inner diameter of the clamping portion 151 , the outer diameter of the insulating connector 13 at the end away from the filament body 11 is larger than the inner diameter of the clamping portion 151 , and the connecting ring groove 132 is provided at the end away from the filament body 11 .

[0040] It can be understood that the outer diameter of the insulating connector 13 gradually decreases from the end away from the filament to the end close to the filament, so that during the installation process, the connector 15 and the lampshade 14 can be naturally connected along the insulating connector 13, which plays a good guiding role, reduces the difficulty of installation, and improves the installation efficiency. When the connector 15 completely passes through the insulating connector 13 and reaches the predetermined position, the clamping portion 151 of the connector 15 is completely clamped into the connecting ring groove 132.

[0041] Furthermore, chamfered surfaces are provided on both sides of the insulating connector 13 to form avoidance surfaces 134 on both sides. The avoidance surfaces are inclined from away from the filament body to closer to the filament body and gradually shrink the insulating connector.

[0042] It can be understood that the beveled surface forms avoidance surfaces 134 on both sides of the insulating connector 13, which provides better guiding when the connector 15 and the lampshade 14 are connected. At the same time, the beveled surface reduces the use of materials and reduces production costs while maintaining the functionality of the insulating connector 13.

[0043] Furthermore, the decorative lamp 1 further comprises a lamp holder 16 for hanging the decorative lamp 1 . A fixing groove 161 is provided in the lamp holder 16 , and a fixing portion 133 plugged into the fixing groove 161 is provided on the insulating connector 13 .

[0044] It can be understood that, through the tight connection between the fixing portion 133 and the fixing groove 161, the decorative lamp 1 can be firmly hung on the lamp holder 16 and is not easily shaken or fallen off due to external force, thereby improving the safety of the decorative lamp 1. The plug-in design simplifies the installation process of the decorative lamp 1, and the installation can be completed without the use of additional tools or complicated operations, thereby improving the installation efficiency and reducing the difficulty of installation.

[0045] In this embodiment, the lamp holder 16 is also made of insulating black rubber material. The outer wall of the fixing part 133 has an annular first groove, and the inner groove wall of the fixing groove has an annular first rib. The first groove and the first rib are interference fit and are used to fix the fixing part in the fixing groove. In order to achieve a better fixing effect, multiple first grooves and first ribs can be arranged along the axial direction. In addition, its installation method is not specifically limited in other embodiments. The fixing part 133 and the fixing groove 161 can also be connected by a snap.

[0046] Optionally, two avoidance holes 162 are relatively arranged on the lamp holder 16, and the wire 12 includes a first wire 121 and a second wire 122, and the first wire 121 and the second wire 122 each pass through one of the avoidance holes 162, and an avoidance groove 163 is formed between the outer periphery of the fixing groove 161 and the avoidance hole 162, and the avoidance groove 163 is connected to the avoidance hole 162.

[0047] It can be understood that the first wire 121 and the second wire 122 pass through the avoidance hole 162. The avoidance groove 163 allows the wire 12 to pass through the avoidance hole 162 smoothly, while also reducing the material used in the lamp holder 16, saving material costs, and reducing the weight of the entire lamp holder 16, thereby improving overall stability.

[0048] Optionally, the lamp holder 16 is provided with a hook 164 and a limiting member 165 connected to the hook 164, one end of the limiting member 165 is connected to the lower end of the opening of the hook 164, and the other end is set higher than the upper end of the opening and forms an inlet between the upper end of the opening.

[0049] It can be understood that when the decorative lamp 1 is hung on a wall or other location through the hook 164, the limiting member 165 will form a barrier at the opening of the hook 164, which can effectively prevent the decorative lamp 1 from falling from the wall or other locations and causing damage when subjected to external forces (such as wind, vibration, etc.). One end of the limiting member 165 is connected to the lower end of the opening of the hook 164, and the other end is set higher than the upper end of the opening and forms an inlet hole with the hook 164, which can improve the stability and safety of the suspension to a certain extent.

[0050] In one embodiment, the limiter 165 can be integrally injection molded with the lamp holder 16, and the wire enters the hook 164 from the wire inlet. Since the material used has a certain elasticity, when hanging the wire, the wire inlet can adapt to different wire diameters according to the usage scenario. Because the limiter 165 and the hook 164 can undergo elastic deformation, when a thicker wire needs to pass through the wire inlet, it can smoothly enter the hook 164. After the elastic reset, the wire is stuck in the hook 164 to prevent it from falling off.

[0051] In another embodiment, the limiting member may be provided at one end of the hook wire inlet via a rotating shaft, and a torsion spring is provided on the rotating shaft. In normal state, the torsion spring drives the limiting member to be in a closed state.

[0052] Further, such as Figure 3 As shown, a decorative light string comprises a main cable 2 and the above-mentioned decorative lights 1 , wherein a plurality of the decorative lights 1 are connected in parallel and / or in series to the main cable 2 .

[0053] A plurality of decorative lamps 1 can be electrically connected in parallel or in series; or alternatively connected in parallel and in series at different positions in a lamp string as required.

[0054] It is understandable that a plurality of decorative lamps 1 strung together into a group of decorative lamp strings is more beautiful, can adapt to the needs of different occasions, and has a wider range of applications. The lamp string wires 12 themselves have a certain connection strength and no longer require additional support.
