Description

Technical Field

[0001] The utility model relates to the technical field of daily lighting equipment, and in particular to a waterproof lamp holder, an electric lamp and a light string. Background Art

[0002] Existing S14 light strings on the market use a soft-glue coating on the lamp holders to achieve waterproofing. This design requires manual injection molding of each lamp holder in the semi-finished light string, which is time-consuming, labor-intensive, and inefficient, resulting in low production capacity and directly increasing manufacturing costs. Furthermore, due to the limitations of the soft-glue coating process, repairs are extremely difficult if the lamp holders experience electrical performance problems, further increasing product maintenance costs.

[0003] The existence of soft plastic coating leads to the irreversible injection molding process in the existing lamp holder manufacturing process, which limits the possibility of product repair when electrical performance problems occur. In short, the current process and structure not only have low production efficiency, limited production capacity, and extended production cycle, but also affect the market competitiveness of the product. Therefore, developing a reversible and easy-to-repair lamp holder manufacturing process is of great significance to improving product performance and reducing costs. Utility Model Content

[0032] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0034] like Figures 1 to 6 As shown, this embodiment provides a waterproof lamp holder, which is designed to improve the waterproof performance of the lamp holder while ensuring the convenience of installation and use. The waterproof lamp holder includes a lamp holder cover 1 and a lamp holder shell 2.

[0035] The lamp housing 2 consists of an outer shell 21 and an inner shell 22. The outer shell 21 is designed as a hollow cylindrical structure, and the inner shell 22 is connected to the inner side of the outer shell 21. The lower end of the inner shell 22 forms a connecting groove 23 for connecting to the bulb housing; the upper end forms a wire groove 24. On opposite sides of the outer shell 21, corresponding to the positions of the wire groove 24, there are relief notches 25. The inner shell 22 is formed with two spaced-apart mounting holes 26 for electrical terminals, which are connected to the wire groove 24. A first connecting portion 27 is also formed on the inner shell 22.

[0036] The lamp cap 1 includes a cover body 11 and a second connecting portion 12 formed at the lower end of the cover body 11 . The second connecting portion 12 is detachably connected to the first connecting portion 27 . The cover body 11 is mounted on the upper end of the outer shell 21 .

[0037] This structural design enables the lamp holder shell 2 to stably fix the electrical terminals and wires, and facilitates connection with the light bulb, thereby improving the installation efficiency of the lamp holder and the reliability of the electrical connection.

[0038] The waterproof lamp holder is designed to improve the waterproof performance of the lamp holder, while simplifying the manufacturing process, reducing costs, and improving the convenience of maintenance. The lamp holder cover 1 and the lamp holder shell 2 are made separately in a detachable manner and can be directly installed through automated operations, thereby greatly improving production efficiency and reducing product costs. After adopting a detachable split lamp holder structure, the lamp holder can be easily disassembled and repaired without damaging the lamp holder and the light string cable, significantly improving the production process pass rate, and when a circuit fault occurs in the lamp holder, the lamp holder can be easily replaced, eliminating the trouble of replacing the entire light string, thereby facilitating after-sales maintenance and service.

[0039] Specifically, a water gap a is formed between the outer peripheral surface of the cover body 11 and the inner side wall of the corresponding outer shell 21, and a drainage hole b is formed between the outer side wall of the inner circumference 22 and the inner side wall of the outer shell 21, which passes through the water gap a and is connected to the drainage hole b. The lower end surface of the outer shell 21 is designed to form a water leakage gap c with the outer side wall of the light bulb.

[0040] The corresponding arrangement of the water-passing gap a and the drainage hole b ensures that water can drain smoothly, preventing accumulation inside the lamp holder and thus improving the waterproof performance. The lower end surface of the outer shell 21 is specially designed to form a water leakage gap c with the outer wall of the bulb. These features work together to effectively prevent rainwater from accumulating inside the lamp holder, enhancing the lamp holder's waterproof capabilities and extending its service life.

[0041] For the lamp holder, the area where the power terminal mounting hole is located is the core power connection area. If it is wetted by water, it will cause poor contact of the lamp, and in severe cases, it will cause a short circuit or scrap. The existing technology uses soft rubber coating, which limits the possibility of maintenance. The present application uses a water gap a, a drainage hole b and a leakage gap to form a drainage structure independent of the core area, ensuring that rainwater can flow directly out of the lamp holder and will not gather inside the lamp holder, which significantly improves the waterproof performance of the core area of ​​the lamp holder.

[0042] In the present application, the inner enclosure 22 includes a support plate 221 and an inner tube 222 . The support plate 221 is connected to the outer shell 21 through a plurality of connecting plates 223 distributed along the circumferential direction. The inner tube 222 is connected to the upper end of the support plate 221 , and the drainage hole b is formed between adjacent connecting plates 223 .

[0043] By setting the support plate 221 and the connecting plate 223, the stability of the inner wall 22 is enhanced, so that it can withstand more weight or pressure; the drainage holes b are formed between adjacent connecting plates 223. Such a design may help to improve drainage efficiency because water can flow out more smoothly from the gaps between the connecting plates. In addition, since the connecting plates 223 are distributed along the circumference, the amount of material required for the support plate 221 may be reduced, thereby reducing costs.

[0044] Preferably, a wire dividing barrier 241 is formed in the middle of the wire trough 24 , and the wire dividing barrier 241 divides the wire trough 241 into two wire passing channels arranged in parallel.

[0045] The two parallel wire passages can effectively accommodate the live wire and the neutral wire of the wires respectively, facilitate the arrangement of the wires, and prevent the wires from being squeezed and damaged inside the wire groove 241.

[0046] In order to facilitate the hanging of the lamp holder, the lamp holder cover 1 further includes a hook 13 , which is connected to the upper end of the cover body 11 .

[0047] In an optional embodiment of the present application, the first connecting portion 27 is a snap-fit ​​groove, and the second connecting portion 12 is a buckle that engages with the snap-fit ​​groove. Alternatively, the first connecting portion may be a buckle, and the second connecting portion may be a snap-fit ​​groove that engages with the buckle. The present application adopts the former connection method.

[0048] The outer circumference of the cover 11 forms a flange portion 111 corresponding to the avoidance notch 25 . The flange portion 111 can effectively limit the position of the wires and ensure the position stability of the wires when they extend from the avoidance notch 25 .

[0049] In order to enrich the hanging methods 111 of the lamp holder, the outer peripheral surface of the cover body 11 is staggered with the avoidance notches 25 to form a hanging rod 112. The hanging rod 112 extends outward along the cover body 11 and then bends downward.

[0050] Based on the above waterproof lamp holder, combined with Figure 7 As shown, the present application proposes an electric lamp, comprising an electric bulb 20, two power terminals (not shown in the figure) and the above waterproof lamp holder 10.

[0051] The shell of the light bulb 20 is threadedly connected to the connecting groove 23 .

[0052] The two power terminals are respectively installed in the power terminal mounting holes 26. The upper ends of the power terminals are formed with sharp parts for piercing the surface of the wire. The sharp parts of the two power terminals are staggered in the width direction of the wire groove, that is, the sharp parts of the two power terminals are used to pierce the neutral wire and the live wire of the wire respectively.

[0053] Based on the above waterproof lamp holder and electric lamp, the present application also proposes a light string, combined with Figure 7 As shown, it includes an electric wire 100 and a plurality of electric lamps 200;

[0054] The electric wire 100 connects all the electric lamps 200 into a string through the wire grooves on the electric lamps 200. The electric wire 100 includes a neutral wire and a live wire arranged in parallel in the width direction of the wire groove. The sharp parts of the two power terminals pierce the neutral wire and the live wire at the corresponding positions respectively. It can be understood that in addition to the live wire and the neutral wire of the AC, in actual use, those skilled in the art can also replace them with the positive and negative wires of the DC power.

[0055] The electric lamp and light string of the above structure have good waterproof effect due to the unique design of the above lamp holder, and are easy to maintain and can be installed directly by automated operation.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
