[0036] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0037] like Figure 1 As shown, this is a lamp body power connection structure 10 according to an embodiment of the present disclosure, including a housing 100, an annular connector 200, a fixing plate assembly 300, and a fixing connector 400. The housing 100 has a wire passage 101. The housing 100 is hexahedral. Please refer to the attached document. Figure 2 The housing 100 has a plurality of mounting surfaces 110, each mounting surface 110 having a wire outlet 1101, each wire outlet 1101 being connected to the wire channel 101, and each mounting surface 110 having an annular embedding groove 1102 and a fixing connection hole 1103.

[0038] Furthermore, the number of the annular connector 200, the fixing piece assembly 300, and the fixing connector 400 is multiple, such as... Figure 4As shown, each of the annular connectors 200 has an annular protrusion 210 at one end, and the annular protrusion 210 is correspondingly embedded in the corresponding annular insertion groove 1102. Please refer to the attached document. Figure 2 The other end of the annular connector 200 is provided with an annular interface groove 201. The fixing plate assembly 300 is installed in the corresponding annular interface groove 201. The fixing plate assembly 300 is provided with a contact pin 310. The fixing plate assembly 300 is provided with a fixing through hole 301. The fixing connector 400 passes through the corresponding fixing through hole 301. The end of the fixing connector 400 is connected to the fixing connection hole 1103.

[0039] In this embodiment, the internal wire is led out from the wire passage 101, and then reliably connected to the rear end of the contact pin 310 on the fixing plate assembly 300 in the corresponding direction. The annular protrusion 210 of the annular connector 200 is aligned with the annular insertion groove 1102 on a mounting surface 110 of the housing 100, and the annular protrusion 210 is inserted into the annular insertion groove 1102. The fixing plate assembly 300 with the contact pin 310 is installed in the annular interface groove 201 at the other end of the annular connector 200. The fixing connector 400 is passed through the fixing through hole 301 on the fixing plate assembly 300 from the outside, and the end of the fixing connector 400 is fastened in the fixing connection hole 1103. The fixing connectors 400, fixing plate assembly 300 and annular connectors 200 in each direction are installed in sequence. The housing 100 of the lamp body power connection structure 10 is selected according to the requirements. The lamp body power connection structure 10 can provide up to six possible wire output directions. The convenient and neat wire exit 1101 can be selected according to the on-site wiring conditions.

[0040] The aforementioned lamp body power connection structure 10 is fitted with the annular protrusion 210 through the annular embedded groove 1102, and the annular connector 200 and the fixing plate assembly 300 are locked and fixed by the fixing connector 400, so that the connection between the components is stable. Multiple wire outlets 1101 of the housing 100 provide multiple wire outlet directions, so that the lamp body installation is not limited by space, improving the flexibility of multi-directional wiring, thereby improving the adaptability and ease of installation of the lamp body assembly. The annular interface grooves 201 of the annular connector 200 are distributed on various planes of the housing 100, and the shared wire passage 101 saves installation space, making the structure of the lamp body power connection structure 10 compact.

[0041] In one embodiment, such as Figure 2 As shown, the fixing plate assembly 300 includes a first fixing plate 320 and a second fixing plate 330, which are installed in the annular interface groove 201. Please refer to the attached document. Figure 3The first fixing plate 320 has a pin insertion hole 3201 and a first connection hole 3202. A portion of the stylus 310 passes through the pin insertion hole 3201. The stylus 310 has a circumferentially formed annular clamping portion 311, which is clamped between the first fixing plate 320 and the second fixing plate 330. The second fixing plate 330 has a second connection hole 3301. The first connection hole 3202 and the second connection hole 3301 communicate with each other through the fixing hole 301. In this embodiment, the annular clamping portion 311 of the stylus 310 is clamped by the first fixing plate 320 and the second fixing plate 330, enabling the stylus 310 to withstand greater axial tensile force, preventing damage during use, and improving the connection reliability of the stylus 310. The double-fixed plate structure of the first fixing plate 320 and the second fixing plate 330 increases the overall rigidity, thereby improving the overall structure's vibration and impact resistance.

[0042] like Figure 2 In one embodiment, a first receiving annular groove 202 is formed within the annular interface groove 201, and a second receiving groove 3203 is formed on the side of the first fixing piece 320 adjacent to the housing 100. The first fixing piece 320 is installed in the first receiving annular groove 202, and the second fixing piece 330 is installed in the second receiving annular groove 3203. In this embodiment, by adapting the first fixing piece 320 to the first receiving annular groove 202 and the second fixing piece 330 to the second receiving annular groove 3203, it is convenient to install the first fixing piece 320 and the second fixing piece 330, so that the installation positions of the first fixing piece 320 and the second fixing piece 330 are fixed, avoiding radial displacement of the first fixing piece 320 and the second fixing piece 330, thereby improving the coaxiality of the first fixing piece 320 and the second fixing piece 330 and the reliability of locking with the fixing connector 400.

[0043] like Figure 3 As shown, in one embodiment, the second fixing piece 330 has a limiting hole 3302, and the end of the stylus 310 facing away from the pin through hole 3201 passes through the limiting hole 3302. In this embodiment, the limiting hole 3302 limits one end of the stylus 310, reducing radial wobbling of the stylus 310. Furthermore, the stylus 310 forms two-point support through the limiting hole 3302 and the pin through hole 3201, enhancing its resistance to bending and lateral forces, thereby improving the stability of the stylus 310 installation.

[0044] like Figure 3As shown, in one embodiment, the first connecting through hole 3202 is formed with a conical countersunk head structure. In this embodiment, the contact area between the conical head of the fixing connector 400 and the conical head of the first connecting through hole 3202 is large, preventing the head of the fixing connector 400 from scratching the first fixing piece 320; when the fixing connector 400 is tightened, its conical head fits against the conical countersunk head structure, making the surface of the first fixing piece 320 flat.

[0045] like Figure 1 As shown, in one embodiment, the first fixing piece 320 also has a plug-in hole 3204. In this embodiment, the plug-in hole 3204 is used to plug into the lamp body, so that the lamp body and the lamp body power connection structure 10 can be quickly and foolproofly connected, thereby improving the safety of the lamp body and the lamp body power connection structure 10.

[0046] like Figure 4 As shown, in one embodiment, the housing 100 has a plurality of flat surfaces 120. In this embodiment, the flat surfaces 120 facilitate the placement of the housing 100, prevent the housing 100 from rolling around, and facilitate operation and storage; when the lamp body power connection structure 10 is connected to the lamp body, the flat surfaces 120 are used as a planar reference for installation and connection, thereby ensuring installation accuracy and efficiency.

[0047] like Figure 4 As shown, in one embodiment, the mounting surfaces 110 and flat surfaces 120 of the housing 100 are transitioned by a rounded chamfer structure. In this embodiment, the rounded chamfer structure eliminates the sharp edges of the housing 100, preventing scratches caused by operators handling and installing it. The rounded chamfer structure is less prone to cracking upon impact, thus improving the structural strength and durability of the housing 100.

[0048] like Figures 5 to 8As shown, in one embodiment, the number of mounting surfaces 110 is two, with each of the two mounting surfaces 110 corresponding to two opposite or adjacent surfaces of the housing 100; or, the number of mounting surfaces 110 is three, with each of the three mounting surfaces 110 corresponding to any three surfaces of the housing 100; or, the number of mounting surfaces 110 is four, with each of the four mounting surfaces 110 corresponding to any four surfaces of the housing 100; or, the number of mounting surfaces 110 is five, with each of the five mounting surfaces 110 corresponding to any five surfaces of the housing 100; or, the number of mounting surfaces 110 is six, with each of the six mounting surfaces 110 corresponding to all six surfaces of the housing 100. In this embodiment, by using a housing 100 with various numbers of mounting surfaces 110, the lamp body power connection structure 10 module can be configured and plugged into different numbers of lamp bodies, improving installation flexibility and thus obtaining combined decorative lamps with different shapes.

[0049] like Figure 9 As shown, this application also provides a modular decorative lamp, including a lighting body and a lamp body power connection structure 10 as described in any of the above embodiments. The connecting end of the lighting body is inserted into the annular interface groove 201 of the lamp body power connection structure 10 to achieve electrical connection. Multiple lighting bodies and multiple lamp body power connection structures 10 are combined and connected to form a three-dimensional decorative structure. In this embodiment, the lamp body power connection structure 10 provides multiple outgoing wire directions, so that the lamp body installation is not limited by space, improving the flexibility of multi-directional wiring, and allowing the lighting bodies and lamp body power connection structures 10 to be combined and connected to form diverse three-dimensional decorative structures.

[0050] Compared with the prior art, this disclosure has at least the following advantages:

[0051] The aforementioned lamp body power connection structure 10 is fitted with the annular protrusion 210 through the annular embedded groove 1102, and the annular connector 200 and the fixing plate assembly 300 are locked and fixed by the fixing connector 400, so that the connection between the components is stable. Multiple wire outlets 1101 of the housing 100 provide multiple wire outlet directions, so that the lamp body installation is not limited by space, improving the flexibility of multi-directional wiring, thereby improving the adaptability and ease of installation of the lamp body assembly. The annular interface grooves 201 of the annular connector 200 are distributed on various planes of the housing 100, and the shared wire passage 101 saves installation space, making the structure of the lamp body power connection structure 10 compact.

[0052] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
