Description

Technical Field

[0001] This utility model relates to the field of string light technology, and in particular to a string light structure. Background Technology

[0002] During holidays such as Christmas, consumers often purchase string lights to decorate and create a festive atmosphere, especially for wrapping lights around Christmas trees, making string lights an essential Christmas decoration. A string light consists of a power cord, a male connector connected to one end of the power cord, and a female connector connected to the other end of the power cord. The power cord is equipped with sequentially arranged string light bodies; each string light body includes a lamp holder and a bulb, with the power cord passing through the interior of the lamp holder and electrically connected to the bulb.

[0003] Referring to Chinese utility model patent CN219414472U, the inventor proposed a novel RGB string light structure, as detailed in the appendix of that patent. Figure 4 and attached Figure 5 The pointed end of the metal terminal 31 pierces into the power cord, and the other end is electrically connected to the bulb. The protrusion at the bottom of the edge of the metal terminal 31 abuts against the power-connecting metal head 41, which is connected to the RGB light source 42.

[0004] The technical solution has the following shortcomings: 1. The metal terminal 31 on the edge is connected to the electrical metal head 41 through the protrusion at the bottom. The lamp head body 32 needs to be provided with a dedicated terminal mounting hole 321. The internal molding of the lamp head body 32 is difficult and increases the step of alignment and insertion during assembly, resulting in high processing costs; 2. Due to the existence of the terminal mounting hole 321, there is a long strip-shaped protrusion on the outer edge of the lamp head body 32 corresponding to the position of the terminal mounting hole 321, which increases the external molding difficulty and cost of the lamp head body 32. Utility Model Content

[0013] In one embodiment, the metal skin includes an integrally formed snap-fit ​​portion and a cover portion, the inner diameter of the snap-fit ​​portion being smaller than the inner diameter of the cover portion, the snap-fit ​​portion snapping onto the lower edge of the tapered portion, and the cover portion covering the outer wall of the base.

[0014] In one embodiment, the base includes a base body, a boss, and a tapered portion arranged in sequence, wherein the outer diameter of the base body, the outer diameter of the boss, and the outer diameter of the tapered portion decrease in sequence.

[0015] The metal cap is engaged with the tapered portion and extends into the interior of the base. The metal skin includes an integrally formed engaging portion and a covering portion.

The metal head includes a protruding first contact portion and an annular second contact portion. An insulating portion is provided between the first contact portion and the second contact portion to make the first contact portion and the second contact portion spaced apart and insulated from each other.

[0018] In one embodiment, the light-emitting component is a lamp panel, which includes a light-emitting substrate and a light source disposed on the light-emitting substrate. The light-emitting substrate is inserted into the base and extends at least into the lamp housing.

[0019] The string light structure also includes a first wire and a second wire. The two opposite ends of the first wire are respectively connected to the light source and the first power receiving part, and the two opposite ends of the second wire are respectively connected to the light source and the second power receiving part.

[0024] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0025] In this embodiment of the string lamp structure, because the second metal terminal is provided with an inclined portion, when the bulb is inserted into the lamp holder, the inclined portion abuts against the top of the second electrical contact portion. The distance between the second metal terminal extending into the outer wall of the base and the inner wall of the lamp holder is short, so the lamp holder does not need to be provided with a dedicated terminal mounting hole. Furthermore, the distance from the second metal terminal to the central axis of the lamp holder is shorter, reducing the radial and axial dimensions of the lamp holder. The outer wall of the lamp holder does not need to be provided with a long strip-shaped protrusion, reducing the molding difficulty and cost of the lamp holder. Attached Figure Description

Detailed Implementation

[0053] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0055] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] Referring to Chinese utility model patent CN219414472U, the inventor proposed a novel RGB string light structure. This technical solution has the problems of difficult forming of the lamp head body, many assembly steps, and high processing cost of the string light structure.

[0057] refer to Figures 1 to 4 To address the aforementioned technical problems, this utility model provides a string light structure 10, which includes a lamp holder 100, a bulb 200, and a light-emitting component 300. The string light structure 10 can be used as a string of lights to create a festive atmosphere, or as a light for other purposes; this utility model does not limit its use in this regard.

[0058] The lamp holder 100 is provided with a first metal terminal 110 and a second metal terminal 120. The bulb 200 includes a conductive base 210 and a lamp housing 220 arranged in sequence. The base 210 is installed inside the lamp holder 100. The lamp housing 220 is provided with a light-emitting component 300. The base 210 is provided with a first contact part 211 and a second contact part 212 that are electrically connected to the light-emitting component 300 on the side near the lamp holder 100.

[0059] When the bulb 200 is plugged into the lamp holder 100, the first electrical connection part 211 is electrically connected to the first metal terminal 110, and the second electrical connection part 212 is electrically connected to the second metal terminal 120. In addition, the first metal terminal 110 and the second metal terminal 120 are respectively connected to the power line passing through the lamp holder 100 so as to realize the power line supplying power to the light-emitting component 300.

[0060] Specifically, the second metal terminal 120 is provided with an inclined portion 121 at one end near the second electrical contact portion 212. When the bulb 200 is inserted into the lamp holder 100, the inclined portion 121 abuts against the second electrical contact portion 212.

[0061] In this embodiment of the utility model, since the second metal terminal 120 is provided with an inclined portion 121, when the bulb 200 is inserted into the lamp holder 100, the inclined portion 121 abuts against the top of the second contact portion 212. Therefore, the distance between the second metal terminal 120 extending into the outer wall of the base 210 and the inner wall of the lamp holder 100 is shorter. The lamp holder 100 does not need to be provided with a dedicated terminal mounting hole. Furthermore, the distance from the second metal terminal 120 to the central axis of the lamp holder 100 is shorter, reducing the radial and axial dimensions of the lamp holder 100. The outer wall of the lamp holder 100 does not need to be provided with a long strip-shaped protrusion, reducing the molding difficulty and cost of the lamp holder 100.

[0062] The specific structure of the lamp holder 100 is similar to that of the Chinese utility model patent with patent number CN219414472U previously applied for by the inventor, and will not be described in detail here.

[0063] refer to Figure 2 and Figure 3 Specifically, in this embodiment, the outer wall of the base 210 is provided with external threads, and the inner wall of the lamp holder 100 is provided with internal threads. The bulb 200 is detachably inserted into the lamp holder 100 through the threaded engagement between the lamp holder and the lamp holder 100. Of course, in other embodiments, the base 210 can also be inserted into the lamp holder 100 by means of snap-fit ​​or other methods.

[0064] refer to Figures 4-12 and Figures 15-20 The first electrical contact part 211 is a metal cap 2111, and the second electrical contact part 212 is a ring-shaped metal skin 2121. The metal cap 2111 and the metal skin 2121 are spaced apart. The metal cap 2111 is snapped onto the top of the base 210, and the metal skin 2121 is snapped onto the outer wall of the base 210.

[0065] The metal cap 2111 is located on the central axis of the base 210, and the annular metal strip 2121 is located on the outer edge of the base 210. Meanwhile, the first metal terminal 110 of the lamp holder 100 is located on the central axis of the lamp holder 100, and the second metal terminal 120 is located near the inner wall of the lamp holder 100. With this configuration, when the lamp holder is inserted into the lamp holder 100, the metal cap 2111 can be aligned with the first metal terminal 110 at any angle, and the metal strip 2121 can be aligned with the second metal terminal 120.

[0066] refer to Figure 10 and Figure 16 In one embodiment, the base 210 includes a base body 213 and a conical portion 215 arranged sequentially. A metal cap 2111 is engaged with the top end of the conical portion 215 and extends into the interior of the base 210. A metal sheet 2121 is engaged with the lower edge of the conical portion 215. The outer diameter of the conical portion 215 is smaller than the outer diameter of the base body 213 to facilitate the insertion of the inclined portion 121 against the metal sheet 2121.

[0067] Furthermore, the metal skin 2121 includes an integrally formed snap-fit ​​portion 2122 and a cover portion 2123. The inner diameter of the snap-fit ​​portion 2122 is smaller than the inner diameter of the cover portion 2123. The snap-fit ​​portion 2122 snaps onto the lower edge of the tapered portion 215, and the cover portion 2123 covers the outer wall of the base 210.

[0068] refer to Figure 12 and Figure 20 In one embodiment, the base 210 includes a base body 213, a boss 214 and a tapered portion 215 arranged in sequence. The outer diameters of the base body 213, the boss 214 and the tapered portion 215 decrease in sequence so that the inclined portion 121 can be inserted and abutted against the metal sheet 2121.

[0069] Metal cap stud 2111 is engaged with tapered portion 215 and extends into base 210. Metal skin 2121 includes integrally formed engaging portion 2122 and covering portion 2123. The inner diameter of engaging portion 2122 is smaller than the inner diameter of covering portion 2123. Engaging portion 2122 is engaged with outer wall of boss 214 to make the connection between metal skin 2121 and base 210 more secure.

[0070] Continue to refer to Figure 12 and Figure 20 Furthermore, the outer wall of the base body 213 near the boss 214 is provided with a recessed limiting groove 2131. The limiting groove 2131 extends continuously along the circumference of the base body 213. A limiting strip is provided inside the cover 2123, and at least a portion of the limiting strip is embedded in the limiting groove 2131. This arrangement prevents the metal sheet 2121 from detaching from the base 210.

[0071] refer to Figure 13 , Figure 22 and Figure 23 The string light structure 10 is provided with a metal head 400, which is sleeved on the end of the base 210 near the lamp head 100. The metal head 400 includes a protruding first contact part 211 and an annular second contact part 212. An insulating part 410 is provided between the first contact part 211 and the second contact part so that the first contact part 211 and the second contact part 212 are spaced apart and insulated.

[0072] In this embodiment, the inner wall of the metal head 400 is provided with an internal thread, and the outer wall of the base 210 is provided with an external thread. The metal head 400 is detachably sleeved onto the base 210 through threaded engagement.

[0073] In this embodiment of the utility model, the metal cap stud 2111, the metal skin 2121 and the metal head 400 are all made of copper, which has good conductivity and low cost. Of course, if conductivity and cost are not considered, conductive materials such as silver, aluminum and iron can also be used.

[0074] refer to Figures 3 to 5 In some embodiments, the light-emitting component 300 is a lamp board 310, which includes a light-emitting substrate 311 and a light source 312 disposed on the light-emitting substrate 311. The light-emitting substrate 311 is inserted into the base 210 and extends partially into the lamp housing 220. The string lamp structure 10 also includes a first wire 510 and a second wire 520. The two opposite ends of the first wire 510 are respectively connected to the light source 312 and the first power connection part 211, and the two opposite ends of the second wire 520 are respectively connected to the light source 312 and the second power connection part 212.

[0075] refer to Figures 6-23 Specifically, the light-emitting component 300 includes a light strip 320.

[0076] refer to Figures 6-14 In some embodiments, the light strip 320 has a first pin 321 and a second pin 322 at both ends, and the base 210 has a first hole 216 adapted to the first power receiving part 211 and a second hole 217 adapted to the second power receiving part 212. The first pin 321 passes through the first hole 216 and is connected to the first power receiving part 211, and the second pin 322 passes through the second hole 217 and is connected to the second power receiving part 212.

[0077] refer to Figures 15-23 In some embodiments, the light-emitting component 300 includes a lamp holder 330 and a light strip 320 located on the lamp holder 330. One end of the lamp holder 330 is inserted into the base 210, and the other end extends into the lamp housing 220. By providing the lamp holder 330, the light strip 320 can be made more stable.

[0078] Specifically, in this embodiment, there are two light strips 320, which are respectively disposed on both sides of the lamp holder 330 and electrically connected. Each of the two light strips 320 is provided with a first pin 321 and a second pin 322. The first pin 321 passes through the first hole 216 and is connected to the first power receiving part 211, and the second pin 322 passes through the second hole 217 and is connected to the second power receiving part 212.

[0079] It is understood that in other embodiments, the number of light strips 320 on the light holder 330 can also be set to one, three, four, etc., and this utility model does not limit this.

[0080] Furthermore, Figure 23 The light-emitting component 300 also includes a resistor 340, which is disposed on the first pin 321.

[0081] In this embodiment of the utility model, the light strip 320 is a ceramic light strip. Ceramic light strips have good heat dissipation performance and stable working characteristics. It can be understood that when heat dissipation performance is not a concern, the ceramic light strip can be replaced with other materials.

[0082] refer to Figures 3-8 In some embodiments, the outer diameter of the base 210 is smaller than the outer diameter of the lamp housing 220. The base 210 and the lamp housing 220 are connected in a sealed manner, and there is a connecting line 600 between the base 210 and the lamp housing 220. The sealed connection can achieve a waterproof effect. That is to say, the base 210 and the lamp housing 220 are molded separately and then welded into a sealed whole.

[0083] Because the bulb 200 is generally a transparent plastic shell formed by blow molding, the size of the opening in the blow molding process affects the processing difficulty and cost. In the case of a one-piece bulb 200, the opening is set at the top of the base 210 during blow molding. In this embodiment, the base 210 and the bulb shell 220 are formed separately. During blow molding, the opening is set between the base 210 and the bulb shell 220, that is, at the position of the connecting line 600. The diameter of the opening is larger, which reduces the processing difficulty of the bulb shell 220. The mature connection process is fast and low-cost, which makes the total cost of the separately formed bulb 200 lower and the molding quality better.

[0084] In this embodiment, the base 210 and the lamp housing 220 are connected together by ultrasonic welding. Of course, the manufacturer can also use other connection methods as needed.

[0085] Reference 15- Figure 23 Specifically, the base 210 is provided with a filler position 700, which is located at the end of the pin or wire near the base 210. The filler position 700 is filled with waterproof glue to prevent the light-emitting component 300 from coming into contact with external water.

[0086] Specifically, the bulb 200 also includes a waterproof rubber ring 800, which is snapped onto the inner wall of the base 210 to prevent moisture from entering the lamp housing 220 from the inner wall of the base 210 and contacting the light-emitting component 300.

[0087] Understandable, except Figure 3 and Figure 15 The illustrated lamp housing 220, the string light structure 10 can also be configured with other lamp housings 220 of various shapes, such as... Figure 24 The schematic diagram shows multiple string light structures with different shaped lamp housings 220.

[0088] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
